SPECIFICATION forming part of Letters Patent N 0. 726,968, dated May 5, 1903.

Application filed May 31, 1901.

To all whom, it may concern:

Be it known that I, LAURENT MORIN, a sub ject of His Majesty the King of Great Britain, residing at Maisonneuve, county of Hochelaga, Province of Quebec, Canada,.have invented certain new and useful Improvements in Woodworking-Machines; and I do hereby declare that the following is afull, clear, and

exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in combination woodworking-machines; and one object in view is the provision of a powerdriven machine by which a variety of operations may be performed on one and thesame machine under the condition that a change (which may be easily and quickly effected) in the position of one or more working devices shall be performed.

A further object is to providea primary tool-shaft with means for adj 'ustably supporting it in place, whereby said shaft may be used in connection with planing, sawing, boring, or pattern-molding mechanisms.

A further object is to equip the machine with an adjustable work-bed and feed mechanism for the purpose of feeding the stock or material to the planing or dressing mechanism from above or below the same to allow adjustment of said bed while retaining its necessary horizontal alinement and to apply or exert pressure on thematerialduring the operation of advancing the latter.

A further object isto allowv certain of the tables tov be used in connection with the sawing and boring mechanisms and to'secure adjustment of the main table so as to clear the primary tool shaft when the position'of the latter is changed and to permit of sawing or cutting the work at, an angle.

With these ends in view the invention consists in the combination, construction, and arrangement of parts, which will be hereinafter fully described'a'nd claimed.

In the drawings hereto annexed, forminga part of this specification, Figure 1 is a side elevation of my combination woodworkingmachine. Fig. 2 is a vertical cross-section on the line 2 2 of Fig. 1 looking in the direc-- tion of the arrow. Fig. 3 is a vertical longitudinal section on the line 3 3 of Fig. 2 look- Serial No. 62,454.

Fig. 7 is a vertical detail cross-section through a front part of the machine in the plane indicated by the dotted line 7 7 on Fig. 1 and looking in the direction of the arrow. Fig. 8 is an enlarged vertical section through a part of the machine adjacent to the revoluble cutter-head on the primary tool-shaft when the latter is adjusted to serve as a means for planing or dressing the stock, said view showing a yieldable counterpoised shield, which is adapted to serve as a chipbreaker. Fig. 9 is a transverse section through a part of the machine, illustrating the primary tool-shaft adjusted to a vertical position and equipped with a cutter-head adapted to operate on the Work for making moldings or cutting grooves. Fig. 10 is a detail sectional plan view, the. plane of the section being indicated by the dotted line 10 10 on Fig. 9. Fig. 11 is a partial end view of the machine, representing the primary toolshaft adapted for the actuation of a boringtool, which is adapted to operate on work placed upon the shiftable auxiliary table of the machine. Fig. 12 is a detail view illustrating themain table equipped with means for supporting the same in inclined positions. Fig. 13 is a plan view of one of the tables equipped with an adjustable metallic plate and adapted to be used in connection with a horizontal cutter-head. Fig--14 is a crosssection through said table on the line 14 14 of Fig. 13. Fig. 15 is a detail perspective View of the counterpoised shield, which may be used under some conditions and in operative relation to a horizontal cutter-head, as in Fig. 8. Fig. 16 is an enlarged detail sectional view of the boring'head. Fig. 17 is a detail-vertical section through a removable bearing adapted to support one extremity of the primary tool-shaft when the latter is adjusted to workin a horizontal position. Fig.

18 is a detail fragmentary view of one of the means employed to hold the horizontal workbed in a fixed position, the same having a section on the line 18 18 of Fig. 1. Fig. 19 is a detail cross-section on the line 19 19 of Fig. 1, illustrating the means for clamping the adjustable rear table in position.

The same numerals of reference denote like parts in each of the several figures of the drawings.

The main frame 5 of the machine may be divided into a right-hand portion 5 and a left-hand portion 5 viewed in Figs. 2, 5, 6, 7, and 9, each portion adapted to support some of the operating mechanisms, which will be hereinafter described. It will of course be understood that the detailed construction of this framework may be varied within wide limits, and the form of said framework herein shown being only one embodiment of the means by which the operating mechanisms are sustained in positions for service.

6 designates a horizontal work-bed, which is arranged longitudinally of the left-hand portion 5 of the framework, Within the latter. This horizontal framework lies between pairs of slotted standards 7 7 7 and one or more other frame-standards 7, the slots in the standards 7 7 7 being indicated at S 8 8. A series of transverse rods 9 9 9 are secured in the bed in positions to extend through the slots in the series of standards, each rod be ing provided at one end with a head 10 (see Figs. 4c and 17) and having its other end threaded for the reception of the hand-wheel 11, a washer 10 being interposed between the head of the rod and the slotted standard, whereby the rods may be tightly clamped against the posts of the framework, so as to solidly support the work-bed in its adjusted position.

I will now proceed to describe the means for adjusting the work-bed in a vertical direction While maintaining the same in a horizontal position at all points of its movement, reference being had to Figs. 1, 2, 3, 5, 6, and 7, inclusive. At the front rear end of the left-hand portion 5 of the frame are provided the stationary frame-rails 13 13, each having a vertical passage la and supporting one of the fixed plates or nuts 15 15, each of the latter being secured firmly to the cross-rail in position for the female threaded opening in the nut to lie in the vertical plane of the passage 14 of the cross-rail. (See Fig. 3. With the nuts (which are maintained in stationary positions by the cross-rails) engage the vertical screw-spindles 16 16, the same passing through the passages 14in the crossrails and arrangedfor the threads of said spindles to engage with the threads of the nuts. The upper ends ofthe spindles bear against thrust-plates 17, which are provided on the under side of the work-head near the end portions thereof, and these spindles are adapted to freely rotate in order to raise or lower them and impart a corresponding adjustment to the horizontal bed. The screwspindle 16 at the front portion of the machine is equipped with a bevel gear-pinion 18, the same arranged to have intermeshing engagement with beveled gear-teeth 19 on a compound gear 19, the latter having an annular series of spur-gear teeth 19", whereby the compound gear 19 is provided with two series of gear-teeth, which are formed by the series of beveled teeth 19 and by the series of straight spur-teeth 19 This compound gear is secured firmly to the end portion of the bed-adjusting shaft 20, the latter arranged in a horizontal position underneath the bed and extendinglongitudinally thereof, (see Fig. 3,) said shaft being journaled near its end portions in hangers 21, which are secured firmly to the under side of the bed, whereby the shaft 20 is journaled on the bed, so as to be carried thereby in its up-and-down movements Within the frame. The rear portion of this bed-adjusting shaft is provided with a bevel-gear 22, which is arranged to have intermeshingengagementwith a beveled gear 23, the latter being secured fast to the screwspindle 16 at the rear of the machine. By reference to Fig. 7 it will be seen that the spur-gear teeth 19 of the compound gear 19 on the bed-adjusting shaft 20 have intermeshing engagement with a spur gear-pinion 25, that is secured firmly to a short horizontal shaft 26, thelatter being suitably journaled in abearing'27 on the under side of the bed 6 at the front portion thereof, said handshaft being provided with a hand-wheel 28, which is adapted to be rotated by the hand of the operator. This hand-shaft 26 provides the means whereby the shaft 20 may be rotated with ease and convenience, and said I shaft 20 through the described chain of gearing is adapted to simultaneously rotate the screw-spindles 16 16, so as to raise or lower them in the nuts 15 5*, whereby the horizontal bed may be raised or lowered and be retained in a horizontal position at all points of its adjustment. It will be observed that it is necessary to loosen the series of handwheels 11 previous to rotating the hand-shaft for the adjustment of the work-bed, that the series of rods 9 9 9 are adapted to travel in the slots of the standards on the adjustment of the bed, so as to limit the latter to vertical movement, and after the bed has been given the desired adjustment these handwheels 11 may be tightened in order to clamp the rods and the bed firmly in their adjusted positions. This work-bed carries a series of idle feed-rolls 29. (Shown by Fig. 3 as consisting of two rolls arranged to protrude through suitable slots in a face-plate 30, although the number of rolls is not material.) Each roll is journaled in a pair of plates 31, which is let into recesses inthe sides of the bed, as shown by Figs. 5 and 6, and with these bearings engage theupper ends of vertical adjusting-screws 32, the latter being suitably mounted in the bed and engaging with the lower ends of the roller-bearings,

whereby the roller may be raised or lowered,

as desired. The plates 31 for the roller shown by Fig. 6 are provided with longitudinal slots '33, through which pass the clamping-bolts 34, whereby the roller-bearings may be clamped laterally against the edges of the bed, and the adjusting-screws 32 are made to assist in holding the hearings in their adjusted positions.

'35 designates an idle upper feed-roll which is arranged practically in the same plane as the rear lower feed-roll 29 in order that it may codperate therewith; but this upper roll 35 is held under yielding pressure in order that it may have normally a tendency to move toward the lower idle feed-roll. The roll 35 has its trunnions slidably fitted in the slots 36, which are provided in the stationary bearing-plates 37, that are fastened to the lefthand portion of the framework 5 (see Fig. 6,) and with the roll-trunnions are engaged the hooked-shaped upper ends of the tensionrods 38, the latter being provided in pairs on opposite sides of the framework-section 5 as shown by Fig. 6, and the lower ends of said tension-rods being engaged with the pairs of springs 39, which are connected by the hookbolts 40 to the bottom portion of the framework.

41 designates a driven feed-roll, the same being arranged in the same horizontal plane as the upper idle feed-roll 35 and disposed substantially in the vertical plane of the front lower roll 29. (See Figs. 3 and 5.) This driven roll 41 consists of a shaft 42 and a plurality of disk-like members 43, the latter being of corresponding diameter, threaded on the shaft, so as to occupy parallel relation, and provided with roughened peripheries, with a View to producing a working surface on said driven feed-roll which will properly engage with the lumber or other piece of wood' desired to be planed. One end portion of the roll-shaft 42 is fitted loosely in a slot 44 of one of the pair of bearing-plates 45. Through the slot in the other bearing-plate of the pair passes the other end portion of the roll-shaft, as shown by Fig. 5. With thisshaft of the driven feed-roll engage the upper hooked ends of the tension-rods 46, the lower ends of which are engaged by the springs 47, that are fastened to the frame, whereby the rods and springs draw the roll 41 downwardly toward the front lower roll 29. the feed-roll shaft passes through a slot 48, which is provided in one of the horizontal rails of the frame, (see Fig. 5,) and to this end of the shaft is secured a spur gear-wheel 49. (See Figs. 4 and 5 and clotted lines in Fig. 3.) This gear-wheel has iutermeshing engagement with an intermediate idler-gear 50, which is loosely mounted on a stub-axle 52, that is'secured to the frame within the section 5 thereof, and said'idler-gear 50 furthermore has intermeshing engagement with a gear-pinion 53 on the hub of a large master- The inner portion of gear 54, the latter being mounted on another stub-axle 55, -secured to a stationary post 56, forming a part of the frame. This mastergear has intermeshing engagement with a gear-pinion 57, which is fast with the hub of a belt-pulley 58, the latter being journaled on a stub-axle 59, also attached to the post 56. tutes a train of reducing-gearing from the belt-wheel to the feed-roll shaft 42, said parts arranged and adapted to propel the feed-roll 41 in the proper direction and to impart a Very slow speed thereto as compared with the speed of the belt-wheel 58. An endless driving-belt 6O encompasses the belt pulley or wheel and is itself driven from the shaft of a motor or from a counter-shaft, (not shown,)v

the train of feed-gearing into and out of serv-v ice by simply adjusting'the treadle-lever 62.

. til

All the before-described gearing consti The horizontal bed and the two series of feed-rolls heretofore described constitute one of the means for presenting work to a primary tool-shaft, which series of work-presenting means are employed in a convertible woodworking-machine contemplated by this invention. My machine also contemplates the employment of a single tool-shaft, which is operatively supported by shiftable devices arranged to present the tool-shaft in horizontal or vertical positions, and with this single tool-shaft I have associated a series of revoluble tools, one or more of which are applied to the shaftin either of its adjusted positions. This primary tool-shaft is indicated by the numeral 65, the same being journaled at points intermediate of its length in proper bearings 66 67, which are provided on the shiftable bed 68,said bearings being arranged at the'end portions of the bed, so as to leave an intermediate space 011 the shaft sufficient to accommodate the wide belt-pulley 69, the latter having a rim 69 at one end, whereby the belt-pulley is secured to the shaft at about the middle thereof, and it is adapted to operate said shaft when adjusted to assume either the horizontal or vertical positions. (Shown more clearly. by Figs. 2and 9.) The end portions of the tool-shaft are exteriorly threaded, as indicated at.70 71 in Fig. 9, whereby said shaft is adapted to receive the rotary tools. I have herein shown the machine equipped with a planer-head,a mold ing cutter-head, a circular saw, and a boringtool head; but I would have it understood that these heads are used interchangeably with the end portions of the tool-shaft and according to the position which the latter may assume in the machine.

The right-hand portion 5 of the frame is provided near the middle portion of the machine with a wide vertical frame-plate 72, the latter having'the' vertical flanges 73, through shown by Fig. 9.

which are bolted the plates 74, said parts arranged, as shown by Figs. 9 and 10, to form the guideways for a vertically-slidable carriage 76. This carriage 76 is arranged to slide up or down in the ways on the stationary frame-plate and any lost motion of the carriage is taken up by the set-screws 77, the latter being screwed into suitable openings provided in the flange of the frame-plate and arranged in a position to engage with an edge of the carriage. (See Fig. 10.)

The tool-shaft bed 68 is connected adjustably or shiftably to the vertically-slidable carriage 76, said bed being movable with the carriage when the latter is raised or lowered and being also capable of a shiftable adj ustment on the carriage independently of any motion thereof. The bed is provided at its middle portion with a transverse slot 78, (see Fig. 5,) in which slot is snugly fitted the beveled head of a bolt 79, (see Fig. 10,) said bolt passing through an opening 80 in the upper portion of the carriage 76 and receiving a clamp-nut 81 at its rear end. Thisbed is shiftable on the carriage by moving it on the axis afforded by the bolt 79, and it will be evident that the bed and the tool-shaft may be turned'to assume the horizontal position shown more clearly by Figs. 2 and 11, or said parts may be turned to the vertical position When the bed 68 and the tool-shaft are in their horizontal positions, the bed is held securely in place by suitable bolts, which are inserted from the rear through apertures 82,provided in the slidable carriage 76, said bolts entering suitable tapped openings in the tool-shaft bed 68. The left-hand end of the primary tool-shaft 65 when the latter and the bed are in the horizontal. positions of Fig. 2 is adapted to be partially supported in a shaft-bearing 83, the latter being provided at the upper portion of a bearingplate 84, which is secured by one or more bolts 85 to the framework portion 5, and this bearing-plate 84 and its associated parts are adapted to be entirely removed from the frame in order to release the tool-shaft 65 and permit it to be adjusted with its bed to the vertical position.

The bed 68 is of a length somewhat less than the width of the slidable carriage in order that it may lie across the latter whenin the horizontal position indicated by Fig. 2; but when the bed is shifted so that it assumes the vertical position of Fig. 9 it is adapted to be held in place by means of bolts (not shown) inserted from the rear through openings 86, which are provided in the lower portion of the slidable carriage 76, as shown by Fig. 2, said bolts being received in suitable tapped openings provided in the bed. It will be'observed that the bed may be turned around on the axis afforded by the bolt 79, that the bed is adapted to be moved across the carriage because the bolt 79 is received within the slot 78, and that the bed may be held securely in either of its adjusted positions by suitable fasteners, which engage with the carriage and with the bed.

87 designates a driving-belt which is operatively fitted to the pulley 69 of the tool-shaft. This belt is adapted to drive the tool-shaft in either of its adjusted positions, because it may be fitted to the pulley 69. In Fig. 4 this belt is shown as encompassing the pulley when the shaft is in its horizontal position; but said belt is adapted to occupy a like relation to the pulley when the tool-shaft is moved to an upright position. The belt 87 may be propelled from a motor or a line shaft, and it serves to drive the tool-shaft independently of the means for propelling the feed mechanism.

Any suitable means may be provided for adjusting the carriage 76 and its contained parts; but in the drawings I have shown a vertical carriage-adj usting shaft 88, having a swiveled connection at 89 with the lower portion of the carriage. (See Figs. 2 and 4.) This shaft is externally screw-threaded for a part of its length in order that it may have engagement with a stationary feed-nut 90, which is provided by a lip or flange on the lower edge of the vertical frame-plate 72, the lower portion of said carriage-adjusting shaft 88 being confined in a suitable bearing 91 at the bottom of the framework. A beveled gear-pinion 92is keyed or splined to the lower portion of this threaded shaft 88 and is arranged to baveintermeshing engagement with a similar pinion 93 on a hand-operated shaft 94, the latter being-journaled in bearings at the lower portion of the machine, as shown by Fig. 4, and provided with a hand-wheel 95, whereby the shaft 88 may be rotated for the purpose of raising or lowering the carriage 76.

When the tool-shaft 65 is adjusted to its horizontal position, its left-hand end portion is adapted to sustain and operate a cutterhead 96 as one of the revoluble tools, while the right-hand portion of the shaft has a circular saw 97 clamped thereto in any of the usual ways familiar to those skilled in the art. This cutter-headand the saw are removable from the shaft, so that other revoluble tools may be secured thereto-such, for example, as the molding cutter-head 98, which is represented by Fig. 9. This last-mentioned cutter-head has two large members 98 clamped thereon and adapted to support the bits 98, although the head members 98 and the bits may be detached, so that provision may be made for the attachment of the smaller head members 98, which are recessed to receive certain other similar bits. (Not shown.) It is evident that any desired size and shape of bits may be clamped to the threaded end 71 of the tool-shaft when in its vertical-position, as shown by Fig. 9, thus enabling the cutter-head 98 to perform a variety of work on the stock, which may rest upon the main table 99, the latter arranged to direct the stock to the cutter-head 98. This disposed in the slot so as to be flush with the top face of the plate. (See Fig. 14'.)

In connection with the circular saw 97 I employ an auxiliary slidable table 125, (see Fig. 2,) said table being of a length equal to that of the machine and arranged at one side of the main table, preferably in the same horizontal plane therewith, although this auxiliary table is adapted to be moved from the position shown by Fig. 2 and placed in the position shown by Fig. 11. The auxiliary table is supported by a table-frame 126, the same having at its end portions the inwardlyextending arms 127, the latter being slidably received in the loops 128, which are fastened to the right-hand portion 5 of the framework, (see Fig. 4,) whereby the table-frame 126 may be moved outwardly from the frame 5, so as to withdraw the arms 127 from the loops 128. The auxiliary table is provided on its under side with the guide-plates 129, which are ar ranged to have underlapping relation to the guide-plates 130, which are fastened on the frame 126 so as to extend longitudinally thereof, the operative relation of the two sets of guide-plates being clearly indicated by Fig. 2. The guide-plates 129 extend lengthwise of the table 125, so that they will embrace the guide-plates 130 in a manner to hold the auxiliary table against crosswise displacement and at the same time permit said auxiliary table to be adjusted in an endwise direction along the frame 126 and close to the position of the circular saw 97. This auxiliary table is thus adapted to serve as a means for feeding a log or other piece of stock to the circular saw, and said auxiliary table may be equipped with any of the usual appliances for holding the log and adjusting the same.

131 designates a saw-gage which is supported on the main table 99 close to the position of the circular saw, and this gage is held adjustably in place byarms, one of which is indicated at 132 in Fig. 2, said arm being fastened adjustably to the table 99 by a clamping-screw 133.

The auxiliary table may be withdrawn from the position shown by Fig. 2 and arranged in the position *shown by Fig. 11, wherein the table occupies a horizontal position below the outer right-hand-threaded portion of the tool-shaft. The table is supported in its underneath position by having its arms 127 fitting in the spaces or ways formed by and between pairs of bars 134, one'pair of which are secured to each end of the right-hand portion 5 of the frame, as'indicated byFig. 11. The bars 127 may be slid to any desired extent into the ways formed by the stationarybars 134, so as-to support the auxiliary table 125 and permit it to be adjusted in a horizontal direction toward and from the frame 5,where by the work supported by the auxiliary table may be forced up to theboring-tool 135.

This tool has its shank fitted in a socket 136 of a boring-head 137, so as to be held therein by the clamping-screw 138, and this boringhead is provided with an internally-threaded socket 139, whereby it may be screwed upon the threaded extremity 70 ofthe tool-shaft when the latter is adjusted to the horizontal position shown by Fig. 11.

When the machine is adjusted for planing work on the bed 6 by raising the latter to the close relation to the cutter-head 96 shown by Fig. 8 and by removing the table 108 from the front portion of the framework, I employ the yieldable chip-breaker 140. (See Figs. 8 and 15.) This chip-breaker is curved in crosssection and tapered to an edge, as at 141, and it is provided with the curved arms 142, the same arranged parallel and having the eyes 143, through which may be passed the pivotal bolts 144, that serve to pivotally connect the chip-breaker to the frame at points above the horizontal plane of the cutter-head 9b and in rear of the latter. The chip-breaker is provided with an outwardly-extending stem 145, on which is shiftably fitted a weight 146, that is clamped adjustably on the stem by a set-screw147, and this weight is arranged to normally press the pivoted chip-breaker toward the bed, whereby the curved device 140 is arranged to intercept the chips and slivers which are cut from the logby the rotary action of the cutter-head 96. The chip-breaker is free to yield or give in an upward direction away from the bed and laterally with respect to the cutter-head, because it is pivoted in themanner shown and described; but the weight 146 normally holds the chip-breaker to its operative position. The downward movement of the chip-breaker, however, is limited by the provision of a set-screw 148, which is screwed into a threaded opening of a lug 149, that is provided on one edge of the chi p-breaker, (see Fig. 15,) and this screw is arranged to rest upon an ear 150 of a stopplate 151, the latter being secured adj ustably to the upper portion 5 of the framework and disposed in the path of the set-screw 148, which is carried by the chip-breaker. The bolts 144 may easily be withdrawn from the frame, so as to permit removal of the chipbreaker, and thus the. entire device may be applied to the machine or removed therefrom, according as it is desiredto plane the work by feeding it to the cutter-head and the bed and through the agency of a feed mechanism.

This being the general and detailed c011- struction of my machine, the operation may be described briefly as follows: With the bed 68 adjusted tothe horizontal position (shown by Figs. 2, 3, 4, 8, and 11) the tool-shaft 65 may be'used for either of the following purposes, to wit: The head 96 is adapted to dress the stock or material which may be fed from the rear to the front on the plate 112 of the rear table, thus presenting the material in the path of the cutter-head 96, at the upper portion thereof, and allowing the material to pass to and upon the plate 109 of the front table 108. The bed Gmay be adjusted in op erative relation to the cutter-head for the purpose'of planing or otherwise treatingalog or other piece of timber adapted to be fed along the bed by the feed mechanism, the driven roll 41 of which is propelled by the train of reducing-gearing. The circular saw 97 may be propelled by the shaft and adapted to operate on a log which is advanced to the saw by sliding the auxiliary table 125 on its supporting-frame 126, or theboring-head 137 may be applied to the shaft 65 in lieu of the circular saw, which adaptation of the machine requires the table 125 to be supported below the boring-tool in the position shown by Fig. 11. The cutter-head 96 and the tool at the other end of the tool-shaft 65 may be dismounted, after which the table 99 may be raised, the bed 68 turned on the pivot adorde'd by the bolt 79, and the threaded end 71 of said shaft 65 may be passed through the openings 101 103 in the table 99 and the plate 102 thereon. This allows the cutter-head 98 to be attached to the upper end of the shaft 65, and the machine may now be operated to produce a desired pattern of molding or for tonguing and grooving purposes.

In using the machine for planing lumber I- prefer to dismount the front table 108 and to pivotally connect the chip-breaker L10 to the frame in a position to overhang the cutterhead 96, as shown by Fig.- 8.

From the foregoing description, taken in connection with the drawings, it will be seen that I have provided a convertible. machine which may be usedfor the performance of a variety ofwork on wood, and, furthermore, it is evident that the change in the machine from one of the revoluble tools to another maybe easily and quicklyperformed, whereby a machine-shop may be equipped with one single machine which will satisfactorily perform the work heretofore required to be done by a number of different pieces of expensive machinery. 7

Changes within the scope of the appended claims may be made in the form and proportion of some of the parts while their essential features are retained and the spirit of the invention'is embodied. Hence I do not desire to be limited to the precise form of all the parts as shown, reserving the right to vary therefrom.

Having thus described my invention, What I claim as new is 1.
