BUNG-BORING AND BUSH-SETTING MACHINE.

Specification of Letters Patent.

Application filed January 31, 1912. Serial No. 674,510.

f/ '0 all whom it may concern Be it known that I, EDWIN F. BEUGLER, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Bung-Boring and Bush- Setting Machines, of which the following is a specification.

This invention relates to a machine for boring bung holes in barrels and setting in said holes metal bushings which receive the bungs or stoppers. Machines for this purpose as heretofore constructed contained but one spindle to which the bung hole boring tool and the bush setting tool were successively attached for the purpose of first boring the bung hole in the barrel and then driving the bushing in said hole. Such interchanging of the tools on the same spindle not only involves a loss of time but also incurs the liability of inaccuracy in the work on account of the constant removal of the tools from the spindle and the attachment of the same thereto for successive boring and setting operations.

It is the object of this invention to pro vide a machine of this character in which separate spindles are provided for the boring and setting tools and which can be brought alternately to the working position without necessitating the removal of the tools from their spindles, thereby enabling the work of boring bung holes in the barrels and the setting of the bushings in the same to be effected more expeditiously, conveniently and accurately.

In the accompanying drawings consisting of 3 sheets: Figure 1 is a front elevation of a machine embodying my invention. Fig. 2 is a vertical transverse section taken centrally through the machine. Fig. 3 is a fragmentary end view taken from the right hand end of the machine. Fig. 4 is a horizontal section of the machine taken in line 4%, Fig. 1, looking upwardly. Fig. 5 is a horizontal section taken in line 55, looking downwardly. Fig. 6 is a fragmentary trans verse section taken in line 6'6, Fig. 1, and showing the construction of the clutch for connecting and disconnecting the machine with the driving shaft. Fig. 7 is a vertical longitudinal section taken in line 77, Fig. 6. Fig. 8 is a fragmentary top plan View of the lower cross piece of the frame showing part of the means for locking the spindle bilge of the barrel supporting yoke in either one or the other of its operative positions. Fig. 9 is a fragmentary top plan view showing part of the means for operating the driving clutch. Fig. 10 is a fragmentary horizontal section taken in line 10-10, Fig. 1.

Similar characters of reference indicate corresponding VleVVS.

The main frame of this machine may be variously constructed but that shown in the drawings is suitable and comprises two uprights or standards 1, 2 arranged at opposite ends of the machine and adapted to rest on the floor, and upper and lower longitudinal girts 3, 4 connecting the upper and lower parts of the standards.

Means are provided for supporting a barrel on the lower part of the frame in positron to be operated upon by the boring and setting tools, this barrel being indicated by dot-ted lines 5, in Figs. 1 and 2, the same having its axis arranged horizontally and lengthwise of the machine so that the boring and setting tools may operate upon the at the top thereof. Although various means may be provided for supporting the barrel in its working position the means shown in the drawings are preferred and are constructed as follows:

In its general organization the barrel support comprises two saddles each of which comprises an upright end wall or web 6, a seat 7 projecting horizontally inward from the lower edge of the web and constructed of downwardly dished or V-shaped form and a supporting arm 8 projecting horizontally and lengthwise outwardly from the upper end of the web. These two saddles are arranged horizontally in line with their seats and webs opposing each other and the same are so adjusted relatively to each other that the underside of the barrel at opposite ends thereof rests 011 the V-shaped seats of the saddles and the ends of the barrel fit loosely between the opposing webs of the saddles. For the purpose of enabling these saddles to be adjusted vertically and also horizontally for enabling the same to support barrels varying in length and diameter each of these saddles is secured to the main frame by means which are preferably constructed as follows :9 represents adjusting blocks slidable vertically on the lower front parts throughout the several side of each of the standards and provided 11 on its rear side with a feather 10 engaging with the outer part of a vertical T-shaped or undercut slot 11 in this standard while its front side is provided with a horizontal groove 12 which receives the adjusting arm 8 of the adjacent saddle. 13 represents a clamping bolt passing through the adjusting block, the horizontal slot in the saddle arm and arranged with its head in the undercut or T-shaped slot or groove of the standard while its nut bears against the front side of the saddle arm through the medium of a washer 14- interposed between this nut and said arm. By moving the adjusting block and saddle vertically on the standard the saddle may be adjusted to barrels of different diameters and by shifting the arm of the saddle horizontally on the adjusting block this saddle may be adapted to barrels varying in length. After adjusting the block and the saddle to the desired position these parts are securely heldin place by tightening the nut of the clamping bolt. After the two saddles have been adjusted to suit the size of the barrel which is to be 0perated upon by the machine these saddles may be further braced for strengthening the same by means of two horizontal tie rods or bolts 15 passing throughcorresponding lugs 16 depending from the front and rear ends of their webs and seats, as shown in Figs. 1, 2 and 5. The tie rods and lugs also serve to support the skids whereby the barrels are guided to and from the machine.

17, 18 represent two upright rotary operating spindles which are arranged parallel and side by side above the barrel when the same rests on the saddles and one of which is provided at its lower end with a boring tool 19 for forming a bung hole in the barrel and reaming the same while the other has'secured thereto a setting tool 20 for turning or screwing a bushing in the bung hole of the barrel after the same has been bored and reamed. These boring and setting tools are of the usual and well known construction and a detail description of the same is therefore not deemed necessary. As shown in the drawings, the boring tool is arranged at the lower end of the left hand operating spindle while the setting tool is mounted on the lower end of the right hand operating spindle.

21 represents a horizontally movable yoke or carrier which supports both of the operating spindles and whereby either of these spindles may be brought vertically in line with the working position relatively to the barrel which is to be operated upon. This yoke is preferably mounted to oscillate horizontally and is pivoted at its rear end between the upper and lower girts of the frame by means of an upright master shaft 22 which is journaled in suitable bearings on said girts. At its front end this yoke is provided with two upper bearings23, 25 and two lower bearings 24, 26, the corresponding two upper and lower bearings being arranged vertically in line with each other and forming a pair and receiving one of the operating spindles. The distance from the axis of rotation of the yoke to the centers or axes of both operating spindles is the same so that upon swinging the yoke about its axis the operating tools of the spindles r travel on the same circle and either of these tools may be brought exactlyto the same operating position. Inaddition to being capable of turning in a horizontal plane in its bearings 011 the yoke each operating spindle is also capable of moving vertically thereon.

While a barrel is being placed on the saddles or removed therefrom both of the'opcrating spindles are elevated. After the barrel has been placed on the saddles the yoke is first turned horizontally until the boring tool is in the working position after which the boring spindle is lowered for causing this tool to form a hole in the barrel and then raised into its inoperative position after the forming of the hole is completed. The yoke is then turned horizontally so as to carry the boring tool away from the working position and bring the setting tool into the working position, after which the respective operating spindle is depressed for causing its tool to screw a bushing into the hole of the barrel and then the operating spindle of the setting tool is again raised to its inoperative position. The raising and lowering of the spindles may be effected by any suitable means but preferably by the means which are shown in the drawings and which are constructed as follows: 27, 28 represent two vertically swinging shifting levers which are pivoted on rearward extensions of the yoke and each of which has its front arm operatively connected with one of the spindles while its rear arm is provided with a counterbalancing weight 29, as shown, or equivalent means for normally causing the front arm of this lever and the operating spindleconnected therewith to be yieldingly held in an elevated position. The preferred means for connecting the front 115 arm of each shiftinglever-with its spindle and still permit the latter to rotate independently of this lever comprises a shifting sleeve 30 mounted on the operating spindle between upper and lower collars 31, 120 32 secured to this spindle and provided on opposite sides with trunnions'33 and longi-x tudinal slots 34 formed in a divided or bifurcated part of the front arm of theshifting lever and receiving the trunnions of the its end portions diverge spindle without interfering with the rotation of the same. Inasmuch as the shift-ing levers are mounted on the horizontally rockin g yoke which carries the operating spindles these parts are always in a definite relation to each other which permits the operator to raise and lower a spindle regardless of the particular position of the yoke.

The upward movement of the spindles under the action of the weighted levers may be limited by any suitable means, for instance, by means of collars 37 secured to these spindles'and engaging with the lower ends of the lower bearings 24, 26, as shown in Fig. 1.

A stop device isprovided for the purpose of arresting the oscillating movement of the yoke so that when the same reaches either extreme of this movement one or the other of the operating spindles is in the working position. This stop device preferably comprises two stop screws 38, 39 arranged on the lower girt of the frame, one in position to be engaged by the lower bearing of the left hand or boring spindle when the yoke is swung toward the left and the setting spindle is in the working position while the other stop screw is arranged to be engaged by the lower bearing of the setting spindle when the yoke is swung toward the right and the boring spindle is in the working position.

Means are provided for locking the yoke when the same is shifted so that either one of its operating spindles is in the working position and the spindle is depressed while in such position. The means for this purpose are preferably designed to automatically lock and unlock the yoke upon lowering and raising the operating spindle while the latter is in the working position. This automatic action of locking and unlocking the yoke may be produced by various means but preferably by the means which are shown in the drawings and which are constructed as follows: 40 represents a verti cally movable locking pin or bolt which is guided in an upright way 41 formed on the front part of the yoke below the spindle shifting levers and adapted to engage with one or the other of two locking openings 42, 43 formed in a lug 44 projecting forwardly from the lower girt, these openings being so arranged that the locking pin is vertically in line with the one at the left when the right hand operating spindle-is in the working position while the other is arranged vertically in line with the locking pin when the left hand operating spindle is in the working position. 45 represents a flexible shifting member consisting, for example, of a cord, as shown in Figs. 1 and 2, which passes with its central part through an eye at the upper end of the locking pin while upwardly from the locking pin and are connected respectively with the front arms of the two shifting levers 27, 28. When both these shifting levers are elevated together with their companion operating spindles both ends of the shifting cord are likewise raised, thereby lifting the locking pin so that its lower end clears the locking lug 44 in which position of these levers this pin is incapable of engaging with either of the locking openings, whereby the yoke may be turned freely about its vertical axis. Upon lowering either one of the shifting levers for moving the companion spindle toward the barrel after the yoke has been shifted to either extreme of its oscillating movement, one end of the shifting cord will be slackened and lowered by the depression of. the respective shifting lever, whereby the locking pin is permitted to drop by gravity into the adjacent locking opening of the lug 44, thereby holding the yoke positively against horizontal displacement while the tool of the particular operating spindle is performing its work on the barrel. Upon again raising this shifting lever for withdrawing the tool of the respective spindle from the barrel that end of the shifting cord connected with this lever is again raised and the locking pin is wit-hdrawn from the locking lug leaving the yoke again free to be turned horizontally. This action occurs regardless of whether one or the other of the shifting levers is lowered and raised so that the yoke is locked either when depressing the boring spindle or when depressing the setting spindle and the yoke is only free to turn horizontally when both the shifting levers and their operating spindles are elevated. By this means either of the tools while operating upon the barrel is held reliably in position and caused to operate accurately on the barrel.

Any suitable means maybe provided for rotating the operating spindles these means being preferably so constructed that these spindles rotate continuously. The preferred means shown in the drawings for thus operating these spindles are constructed as follows z-The lower part of each of the operating spindles is preferably journaled directly in its lower bearing on the yoke but the upper parts of these spindles are journaled in the upper bearings of the yoke by passing these spindles through hubs 47, 48 which are journ'aled in the upper bearings 24, 26 and which are provided respectively at their upper ends with gear wheels 49, 50. Each of these hubs and its companion gear is pre vented from moving vertically by engaging the respective gear with the upper end of the companion bearing and providing the lower end of its hub with a collar 51 which bears against the lower end of this bearing, as shown in Fig. 1. Each of the spindles is compelled to turn with the hub of its gear but is capable of sliding axially through the same by means of a spline 52. The gear wheel 49 of the boring spindle is comparatively small and forms a pinion which meshes with a larger gear wheel 53 on the upper part of the master shaft, and the gear wheel 50 of the setting spindle is comparatively large and meshes with a smaller gear wheel or pinion 54: mounted on the master shaft below the gear wheel 53. By this relative timing of the gearing the boring spindle which operates upon wooden staves of barrels is rotated at a comparatively high speed from the master shaft while the setting spindle is rotated at a comparatively slow speed from the master shaft, such slow speed being required for setting the bushing in the bung hole, thereby rotating these spindles differentially from the same source to suit the Work which the respective tools must perform.

The master or intermediate shaft 22 is rotated by means of a horizontal driving shaft 55 journaled lengthwise in hearings on the upper ends of the standards and provided with a bevel gear pinion 56 which meshes with a bevel gear wheel 57 mounted on the upper end of the master shaft. By this means motion is transmitted from the driving shaft to the spindles which permits the latter to rotate continuously while the yoke is being shifted horizontally and while the spindles are being moved vertically toward and from the barrel.

Various means may be employed for driving the shaft 55 and connecting or disconnecting the same from the prime motor or source of power. The means shown in the drawings are preferred and constructed as follows :58 represents a spider secured to the driving shaft and provided with a plurality of radial clutch shoes 59 the outer ends of which are beveled so that together they form a conical clutch surface. 60 represents a driving pulley which is adapted to be engaged on its periphery by means of a driving belt and which is provided on the inner side of the front edge of its rim with a conical clutch face which is adapted tobe engaged with or disengaged from the inclined faces of the clutch shoes upon moving the driving pulley lengthwise on the driving shaft and thereby either cause the driving shaft to turn with the driving pulley or cause the latter to turn idly while the driving shaft is at rest. 62 represents a coupling spring surrounding the driving shaft and bcaring'at its rear end against a coller 63 secured to the driving shaft while its front end bears against a presser disk 64 which is mounted loosely on the driving shaft and engages with the adjacent rear end of the hub of the driving pulley. When unrestrained the spring 62 causes this pulley to engage its clutch face with the clutch shoes and thereby couple'the driving shaft with the prime motor. When, however, the pressure disk 64 is moved rearwardly and the spring 6.2 is compressed an auxiliary or uncoupling spring 65 interposed between the front side of the driving pulley and the rear side of the clutch spider, as shown in Fig. 7, operates to move the driving pulley slightly rearward sufliciently to disengage the clutch face of the driving pulley from the clutch shoes, thereby disconnecting the driving shaft from the prime motor. The pressure disk at this time is moved a sufficient distance rearwardly from the hub of the driving pulley so that the same does not engage with the hub of this pulley, thereby eliminating the frictional contact between these parts which otherwise would occur while the machine is at' rest, thereby avoiding undue wear. The movement of the pressure disk rearwardly from the driving pulley is preferably effected by means which comprise a horizontal shipper rod 66 guided lengthwise in ways on the upper part of the main frame, a fork 67 mounted on the front end of the shipper rod and arranged so that its prongs straddle the rear end of the hub of the driving pulley and stand in front of the pressure disk, a thrust or bearing collar 68 secured to the rear end of the shipper rod adjacent to the outer side of the right hand standard and provided with inwardly facing bearing lugs 69 on its diametrically opposite sides, and a vertically swinging shipper lever 7 0 pivoted on the outer side of the right hand standard and provided on its upper arm with a curved slot 71 which receives the rear end of the shipper rod and with cam faces 72 on opposite sides of this slot which are adapted to engage with the bearing lugs of the thrust collar. As shown in Figs. 8 and 9 the shipper lever is so turned that the low part of its cam faces are out of engagement from the bearing lugs of the thrust collar and when this lever is in this position the shipper fork occupies the position shown in Figs. 1, f and 7 in which it does not engage with the front side of the pressure disk, thereby permitting the coupling spring 62 to press the driving pulley against the clutch shoes and couple the driving shaft with the driving mechanism. Upon turning the shipper lever in the direction of the arrow its cam faces engage the bearing lugs of the thrust collar, thereby moving the shipper rod rearwardly or toward the right, whereby the shipper fork pushes the presser disk away from the driving pulley so that the latter is free to be disengaged from the clutch shoes by the uncoupling spring 65 and cause the machine to be stopped.

It will be noted that the boring and set-' ting tools in this machine are always ready for use and that the same are not applied to and removed from the machine for performing the bung hole boring and bush setting operations on successive barrels, thereby enabling the out put of the Workman to be materially increased Without any increased effort on his part.

This machine as a whole is very strong, durable and compact in construction, it has no delicate parts which are liable to get out of order, and the same can be easily, quickly and conveniently operated.
