DOWELING-NIACHINE.

SBEClFICATION forming part of Letters Patent No. 705,657', dated July 29, 1902.

Application filed March 14, 1902. Serial No. 98,170. (N0 Infidel-3 To all whom, it may conceru Beit known that we, WILLIAM J. EDWARDS and WILLIAM M. VVAUTERS, citizens of the United States, residing at Bayonne, county of Hudson, State of New Jersey, have jointly invented a certain new and ImprovedDoweling-Machine, of which the following is a speciiication.

This invention is primarily intended for Ause in the manufacture of wooden boxes and bar reis, but is applicable to other uses; and its object is to provide a machine by which the sections of a barrel-head or two pieces `of board designed to form an end or side of a box may be securely united by dowels.

The form in which we have elected to disclose our invention is that of a machine for doweling sections of box ends or sides. Experience has demonstrated'that this embodiL ment of the invention is a practical and eiiicient one, and it is the form now best known to us. Nevertheless the invention may be embodied in other forms, and some features may be used without others and in machines otherwise differing from that herein shown.

In the accompanyingdrawings, Figure 1 is a sideelevation; Fig. 2, an end elevation; Fig. 3, a plan, on an enlarged scale, with some of the `parts broken away and some omitted; Fig. 4, a view, on the same scale as Fig. 3, of the upper part of the machine, partly in side elevation and partly in section, on the lines 4 4 and 4 4; Fig. 5, a detail View on an enlarged scale, showing part of the main crankshaft and the connection for actuating the sliding head that `forces the boards together. Figs. 6, 7, 8, 9,10,11, and 12 are detail'views of different parts of the machine; Fig. 13, a detail section showing the dowel-hopper and one ot' the channeled arms in which it is pivoted; Fig. 14, aplan View of the hopper; Fig. 15, a section on the line 15 lef Fig. 14; Fig. 1G, a section on the line 1G `1G of Fig. 14; Fig.- 17, a section on the line :17 17 of Fig. 14; Figs. 1S, 19, and' 2O are diagram views illustrating the doweling of twosboards, and Fig. 2l a detail sectional view showing two boards united by dowels and lying between the dowel-holders.

ordinarily employed by mechanicians, although in some minor features there maybe novelty in details of structure.V

ln this machine two pieces, which together form a symmetrical part or whole of a box side or end or barrel-top and the abutting edges of which have preferably been drilled previously in any suitable way to receive the dowels or securing-pieces, are placed upon the bed of the machine on opposite sides of appropriately-located dowel-holders. Then while appropriately held the edges of the pieces are forced together and upon the dowels which unite them, however irregular or whatever may be the angular position of the joint. The dowel-holders are automatically supplied with dowels for the next pair of pieces to be united, and the dowels are automatically fed for this purpose from a hopper.

The bed-plate A of the machine is appropriately supported by anysuitable frame, and on one end thereof is mounted a sliding head `B,which receives its motion from a rockinghead arm B, as hereinafter described. .That part of the bed-plate to the right of the sliding head forms the table upon which the pieces to be united are placed, and at the rear edge thereof asuitable gage or stopplate A' is mounted. On opposite sides of this part of the bed-plate are mounted sliding dowelholder frames, each constructed as follows: There is an angled plate C, constituting the slide and formed with or carrying a yoke which, Fig. 3, first extends outwardly, then to the right `parallel with the bed-plate, then upwardly and to the left, overlyingits lower part, and the two ends of the yoke terminate oppositeeach other, being, formed with hubs or tubular parts C2, whose axes are vertical and coincident. These hubs carry opposed dowel `holders or clamps D, having stems (Z, fitted to slideinrthe hubs and guided by pins d', work-ing in slots therein, and are urged toward eachother yieldingly by springs conn tained within the hubs, and the upper one of which is shown in Fig. 4. The right and left hand edges of the dowel-holders are beveled inwardly, Figs. l and 21, and their contiguous faces are formed with opposite grooves cl3, parallel with the line of reciprocation of the IOO slide B and in which the double pointed dowels Z are held and clamped. A pin c projects from the inner face of each dowel-frame slide C through an elongated slot c in the vertical wall of the bed-plate and is engaged by the forked end of a rocking arm E, loosely mounted on a rock-shaft E and connected by a coiled spring B2 with the rocking arm B, that actuates the sliding head. The mode of operating the arms E is hereinafter described. At the moment it is sufficient to know that they may rock independently on their shaft E and also that they can be positively moved together to the right for the following purpose: Atk the right-hand end of the table and on each side thereof, opposite the dowelholders, is mounted a radial receptacle F, to which the dowels are automatically fed, as hereinafter described, and from the bottom of which, lthrough an aperture in the projecting edge or base f of the receptacle, dowels are at the proper time, by means of an automatically-actuated plunger f, forced out of the receptacle and into position between the dowel-holders D, as indicated, for instance, in Fig. 4. The lever G, pivoted at G at the extreme right of the bed-plate, extends to the left over the bed-plate and has pivotally mounted in its end a presser-plate (El2 for bearing upon and holding the pieces of board deposited upon the bed-plate. A spring G3, Figs. 1 and 6, tends normally to draw the arm downwardly and is permitted to do so at the proper time, as hereinafter described.

We will first describe the operation of doweling two pieces and then the mechanism by which the parts of the machine thus far referred to are actuated.

The dowel-holders D being in the position indicated in Fig. 1 and dowelsZ being clamped between them two pieces .of board Y Y, the edges of which, preferably, as indicated at y, have been drilled, are laid upon the table A on opposite sides of the dowelholders. The presserplate G2, the leading edge of which is above or turned upwardly, descends. The sliding head B advances, carrying the adjacent board Y with it and presenting its edge or the drilled holes therein to the dowels held in the holders D. If this edge of the board is of irregular contour or is at an angle other than ninety degrees to the front and rear edges of the board, one of the dowelholders will be pushed ahead of the other until finally the edges of both pieces of the board are forced against the dowels in the two holders. As the slide advances and the dowels enter the apertures in the edges of the boards the holders D D, being beveled, are forced apart by the strain, and the opposite edges of the board are pressed together. At this time the projecting edge or basefof the dowel-receptacles forms an abutment against which the pressure is exerted. The operation is shown in Figs. 18 to 21, inclusive. The slide B recedes, the presser G2 rises, and the operator now withdraws the united boards from between the dowel-holders D, and these holders are then positively advanced to the position indicated in Fig. 4, whenthe plungers f are operated and dowels are again forced into position between them. During this action the presser-plate G2 has been raised and the sliding head B'has been retracted. The dowel-holders, each carrying a new dowel, are now returned to the initial position (indicated in Fig. 1) and the operator may place upon the table A another pair of boards to be united. We prefer that the machine should come to rest in the initial or normal position shown in Fig. 1 and be set into operation at the will of the operator to perform the general operations described, and we have accordingly so shown it.

At one end of the frame is a driving-shaft 1, having at one end a pulley 2, driven by a belt 3, and at the other end, keyed to it, a pinion 4, meshing with and driving a gear 5. The pinion and gear are shown as inclosed in a casing 6. The main shaft 7 of the machine is to be driven intermittently at the will of the operator, and this may be accomplished by any appropriately controlled clutch devices. Those shown are as follows, Figs. 1, 2, 11, and 12: The shaft 7, lying within the hub of the wheel 5, has formed in it a longitudinal segmentary groove 8, in which fits a correspondingly-shaped part 9 of a locking key or clutch 10, that rocks in a bearing on a sleeve 11, surrounding a shaft. The outer face of thepart 9 of the key is formed or cut so as to be coincident with the periphery of the shaft. At one or more points the bearing-hub of the wheel is formed with internal recesses 12. Fast on one end of the part 10 is a radially-projecting arm or tailpiece 13, to which one end of a coiled IOO spring 13 is attached, the opposite end of the spring being secured to the sleeve 11, Fig. 11. The arm 13 is normally held by a stop 14 in such position that the wheel 5 revolves freely Without actuating the shaft. The stop 14 is shown as a straight arm attached to the end of a rock-shaft 15, arranged at right angles to the shaft?. From the opposite end of the shaft 15 projects a radial arm 16, connected by a link 17 with a treadle 18, hinged to the frame at 19. A spring 20, attached at one end to the stop-arm 14 and at the other end to the frame, serves to hold the parts in the normal position. (Indicated in Figs. 2 and 1l.) When the operator depresses the treadle, the stop 14 is moved out of engagement with the arm 13, the spring 13 partially rotates the clutch-piece 10, and one of the angular edges of the part 9 thereof engages one of the recesses 12 in the hub of the wheel. The foot of the operator being removed from the treadle the shaft 7 will be rotated through one revolution, when the parts are restored to normal position by abutment of the arm 13 against the stop 14. On the movement of the shaft 7 the centrally-located crank 21 thereof actuates an arm or pitman 22, Figs. l and 5, jointed IIO to the rocking arm or lever B', the upper end of whichis connected by a link b with the underside of the sliding headB. The connection between the crank and rocking arm B is composed of two pieces one sliding in the other and provided with a spring 23, which cushions the pressure of the sliding head on the abutmcnts in the operation already described, andwith a collar 24, which positively connects the two parts on thereturn motion. started forward, the presser-plate G2 is allowed to descend, and this may be conveniently accomplished as follows: A sprocketwheel 25 on the rear end of the shaft 7 carries a drive-chain 25,running over a sprocketwheel 26, having a double number of teeth and mounted in bearings, as shownin Fig. 1, at the right side of the machine. The shaft 27, to which the latter sprocket-wheel is fast, carries a double cam 2S, the two portions of which are of corresponding contour and project, respectively, on opposite sides of the shaft.` This sprocket-wheel and shaft will make one half-revolution for each full revolution of the main shaft 7. The horizontal arm of a right-angle lever 29, Figs. 1 and 6, rocks loosely upon a shaft 30, and its downwardly-extending vertical arm carries a roller that bears upon the sections of the double cam 28. At the angle of the lever 29 is jointed a rod 31, which passes upwardly through volve in the direction of the arrow the rod 31` will be permitted under the stress of its spring tomove downwardly quickly until the presserplate G2 bears upon the boards lying on the bed-plate, and ,when the half-revolution of the shaft 27 has been` completed obviously the presser-plate will have been again raised to its normal position. y

In the operation of doweling, the two boards having been completed, the operator withdraws them from between the dowel-holders D,'and a cam 32, Figs. 1l, 2, and 10, located near the rear end of the main shaft 7, acts upon a roller 33 in the end of a horizontal arm 34, which is supported by an upright pivoted arm 35, mounted on a frame and the other end of which is connected to a radial arm 35, (indicated by dotted lines in Fig.` 1,) on the rear end of the rock-shaft E. Keyed to this shaft, Figs. 8 and 9, is a radially-projecting arm 36, having a cross-head 37, in the ends of which are mounted two set-screws that bear, respectively, upon the two arms E E, :that actuate the sliding dowel holder frames. Consequently the dowel holders are moved to the right by a positive motion VVheu the sliding head B is,

into proper juxtaposition, Fig. 4, to the dowelreceptacles F F, and the plunger f thereof being actuated dowels are ejected and forced between the holders, as shown in Fig. 4. Vhen this operation has been completed, Jdie roller 33 passes from the high point of the cam 32, and under the stress of the springs B2 the two arms E E are quickly retracted to bring the dowel-holders into their normal central position. While the dowel-holders were in proper juxtaposition to the dowel-receptacles the Vcam 39 acted upon the roller 40, mounted on the pivoted uprightarm orlink 4l, and moved to the right the horizontal arm 42, connected with the upper end of the arm 41. This arm slides in a bearing 43 in a bracket bolted to one of the uprights in the frame, and between said bearing and a collar 44, fast on the rod, is placed a coiled spring 45, that serves to return the rod to the left into normal position as the roller` 4l runs upon the fall of the cam 39. Beyond the bearing 43 the rod is extended and passes through the lower end of a radial arm 46, extending from the rock-shaft30, having bearings in brackets mounted on the right-hand side of the frame. A collar 48 is applied fast to the rod outside of the arm 46, and between the end of that arm and the bearing 43 is interposed a compressible coiled spring 49. As the rod moves to the right the arm 4G is yieldingly acted upon. On the rock-shaft are two upwardly-extending arms 50, which` extend into apertures 51, Figs. 1 and 7, of the re- IOO spective heads of the reciprocating plungers f', which are mounted to slide in bearings in the right-hand end of the frame. `The plungers are therefore moved to the left to eject dowels from the `receptacles F into the opposed dowel-holders D. The spring 49 is provided to cushion the action of the plungers in the event of any obstruction to the free discharge of the dowels fromthe receptacles.

Extending upwardly andoutwardly from each dowel-receptacle are arms or brackets 52, formed with dowel-channels 53 in their upper faces, and the dowels Z, Fig. 4, descending by gravity through this channel fall one upon another in the vertical dowel-receptacle F. In the upper ends of the`brackets 52 is hinged a hOppel?, Which is preferably of the construction shown in Figs. 13 to 17, inelusive-that is to say, it has an oblong receptacle having parallel sides 54, inwardlyinclined ends 55, and on each side of the lon- IIO gitudinal center `of the hopper the bottom fall through the slots 58,1ie end to end in the i In rear orto the right of the pivotal axis shaft 63 has its bearings.

channels 59, and these channels communicate with the channels 53 in the brackets or arms 52, so that the dowels slide downwardly into the receptacles F, Fig. 4. Their passage, however, down through the channels 53 in the brackets 52 is controlled in the following manner: Mounted upon each bracket 52 is a block or part 62, in the upper ends of which a rock- A radial arm 64 on this rock-shaft is connected by a link 65 with the rocking arm or lever G. On each end of the rock-shaft 63 is a cross-head 66, in the opposite ends of which two feed-regulating plungers 67 68 work, coiled springs 69 being applied around them. These feed-plungers are in line with the channels 53 in the brackets 52 and work in guideways or apertures in the block 62, Figs. 1 and 13. As,

therefore, the arm or lever G rises the lower feed-plunger 68, or that to the left, is raised and the other one, 67, is lowered, this condition being indicated in Fig. 13. The interval between the two feed-plungers is approximately equal to the length of the dowel, and consequently when the feed-plunger 67 descends it arrests or blocks the dowel above it, while the dowel immediately below it and which previously had been arrestedby the feed-plunger 68 is allowed to slide downwardly into the dowel-receptacle F, Fig. 4. In this way the receptacles are kept supplied with dowels. v

The dowel-hopper is manipulated as follows in order to insure a supply of dowels for the channel-ways 58 and 53. The hopper is pivoted at 61 6l in the upper ends of the arms or brackets 52, with the center of gravity materially to the right of the pivotal axis. A suitable number of dowels Z are placed in the hopper, and in the operation of the machine the following action occurs: The shaft 27, as before stated, is rotated through half a revolution during one revolution of the main shaft 7, and from the front end of the shaft 27 projects a radial arm 70, Fig. 1. From its end a cord or chain 7l` extends to the hopper to the left of its axis of oscillation. During one half-revolution of the shaft 27 nthe lefthand end of the hopper is drawn downwardly into the position shown in Fig. 13 and on the next half-revolution it is allowed to rock into the position shown in Fig. l. When in the position shown in Fig. 13, the dowels naturally fall to the front, as indicated, and when rocked back, as in Fig. 1, the dowels shift or slide to the right and in so doing they are by the action of inclined sides 56 57 caused to arrange themselves in line and fall through the slots 5S into the channels 59, from whence by gravity they descend into the continuations 53 of such channels, formed in the brackets 52. It is contemplated that when the rope or chain 7l rises the right-hand end of the hopper will rock downwardly without being specially weigh ted for that purpose, the weight of the bars 60, in which the channels 59 are formed, being sufficient to produce this action. However, the same result may be accomplished by properly apportioning the relative length to the right of and to the left of the axis on which the hopper rocks, or, if desired, an adjustable weight 72 may be attached to the bottom of the hopper near its right-hand end.
