TRIMMING AND DRILLING IVIIACHINE.

' SPECIFICATION forming part of Letters ratent No. 601,379, dated March 29, 1898. Application filed August 10, 1897. Serial No. 647,747. (No model.)

To aZZ whom it may concern: I

Be it known that I, ARTHUR J. MORSE, of Salisbury, in the county of Litchfield, in the State of Connecticut, have invented new and useful Improvements in Trimming and Drilling Machines, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to machines for trimming the ends and drilling nipples for bicyclespokes or analogous or similar devices; and the, object is to provide a machine that will operate on several nipples or other articles simultaneously, producing a somewhat different operation on each, and that will operate upon a series of nipples successively.

To this end my invention consists in the combination, in a nipple-finishing machine, of a disk provided with chambers to hold the nipples, means to rotate the disk intermittently,a longitudinally-movable bar, the driving-shaft, a cam-wheel on the driving-shaft to move the bar, a spindle adapted to be reciprocated in bearings by the said bar, a chuck on the end of the spindle to hold a tool to operate upon the nipples, and a pulley on the spindle for rotating the same; and my invention consists in certainother combinations of parts, hereinafter described, and specifically set forth in the claims.

In the drawings hereto annexed and forming a part of this specification, Figure 1 is a top plan view of my invention. Fig. 2 is a front side elevation. Fig. 3 is the rear side elevation. Fig. at is anend elevation looking from right to left of Fig. 1. Fig. 5 is the same end view of some of the important movable parts shown in their operative position or the reverse of that indicated in Fig. 4:. Fig. 6 is an end view of the machine, looking from left to right of Figs. 1 and 2. Figs. 7 to 9, inclusive, show different views of the trimming-chuck. Fig. 10 shows an end and side view of the trimming knife or cutter, and Figs. 11 and 12 show side and sectional views of a nipple. I

Referring specifically to the drawings, A is the frame of the machine, having forward extensions a and ct for the pair of spindles B and C to turn in, and rearward extensions 1) b for the driving-shaft D to turn in. The spindles B of the sliding bars.

and C are parallel with each other and lie with their axes in the same horizontal plane.

The drivingshaft D carries a 'pair of cam wheelsD and D, the cam-surface of each being on one side of the rim and on the sides facing each other. These cam-wheels operate upon a pair of longitudinally-movable ,bars E and E, sliding in a guideway E, ar-

ranged on the top of the frame A, parallel with the driving-shaft D, through a pair of small rollers d and d, turning on one side The right-hand end of bar E slides in another bearinge on the frame.

The sliding bars E and E are in line with each other and are carried toward each other by the cam-wheel's simultaneously, as hereinafter explained. The bar E is connected by a forwardly and horizontally extending bar F with the right-hand ends of the spindles B and C to reciprocate them in their bearings while they are being rotated by con tinuously-running belts (not shown) on their pulleys B and C. The sliding bar E and the spindles B and C are threaded where they pass through the bar F, so that nuts f f and f. f on said bars and spindles on opposite sides of the bar F may properly adjust the bar F. The nutsf f do not bind on the sides of the bar F, but are separated sufficiently to allow the spindles B and C to rotate. The left-hand ends of the spindles are shown provided one with a trimmer-chuck c and the other with a drill-chuck a, so that both operations may be effected on a pair of nipples at once; but, if preferred, both chucks maybe either trimmer-ch11 cks or drill-chucks, and if both are drill-chucks the chuck on spindle B may carry the drill for the smaller hole in the nipple, as indicated in Fig. 12 of the drawings, while the other chuck may carry the larger drill for the unthreaded portion of the spoke to enter. It becomes necessary in this case, as is obvious, to extend one drill farther than the other, and this may be efhold the nipples.

the nipples, and is provided with adjustable screws 9 and 9', extending through it in line f with the spindles B and O on the opposite side of the disk G, which are for the purpose of bearing on theheads of the pair of nipples being operated upon by the trimming-cutters or the drills. The ends. of the screws 9 and g serve to hold the heads of the nipples firmly drills begin to act on the nipples,'and said screws are moved from the heads after such operation is completed, when the disk G again turned.

Ooilsprings h and 71. areconnected with the sliding bars by pins projecting through slots,

in the guideways to retract the bars.

' X is the-driving-pulley on the driving-shaft. The disk G, carrying the nipples to be operated upon, is secured upon one end of a horizontal shaft G, which turns in bearings g" and g in a bracket G, secured to the front side of the frame A. The disk G is provided with a circular and concentric series of holes or chambers w 00, the, which extend.

through it near its periphery to receive and Twenty holes are shown in the disk in the'drawings, and these holes are just large enough to admit the shanks of the nipples, which before they are trimmed resemble common rivets and are countersunk slightly to receive the heads. Countersinking the holes 00 helps the screws g and g to hold the nipples from turning. The nipples are inserted-by hand in the lower part of the disk, which revolves in the direction of the arrows shown in Figs. 1 and at. \Vhen a nipple reaches a point forty-five degrees above a horizontal plane extending through the axis of the shaft G, it is trimmed and centered by the knives in the trimming-chuck, as indicated in Fig. 11 of the drawings, after which it is carried step by step-a nipple being trimmed at each step by the same chucka distance of ninety degrees, when it is in position to be drilled by thedrill in the chuck 0. After the same nipple is carried by the disk to nearly its lowest point it is in position to be removed by the rod H, extending horizontally near the lower part of the frame. The said rod is in line with one of the nipples in the disk when the trimmer and drill are operating upon other nipples, and as the rod H, which may be termed a pusher, is connected to and operated by the bar Fit pushes a nipple out of the disk every time the spindles B and G are moved toward the disk.

The pusher H is reciprocated in an aperture in the end of a depending arm 2', secured by a bolt to the web below the bearing g. The end of the pusher farthest removed from the disk is secured adjustably in the lower end of an angular armll, secured to the barF.

The shaft G is rotated intermittently by means of a ratchet-wheel J on the end oppositeithat carrying thedisk G. The ratchetwheelis provided with as many teeth as there are holes for nipples in the disk, the number in this case being twenty. The recesses in the periphery or thespaces between the teeth are shown square-and are preferably made so in order that the disk may be held positively against movement in either direction during the trimmingand drilling operations.

J is the pawl forturning the ratchet-wheel J. Said pawl is connected at one. end with a lever K, which is pivoted at its lower end to a projection Z, extending from the angle of a bell-crank lever L, which is inturn pivoted at'its angle to the frame A. One armof the bellecrank lever extends horizontally to and below the ratchet-whee1, audit-send is adapt ed to enter the recessestherein and forms the detent ofsaid wheel, and the other arm extends vertically, and is in position to be im-.

pinged by an adjustable screw 70, passing through the lever K.

' A coil-spring m connects the pawl J with the detent-arm of thelever L and serves to draw them toward each other. Another coilspring nis connected between the pawl J and a bracket I, secured to the frame to operate on the pawl to turn the ratchet-wheel J. The pawl J is moved in theopposite direction and the detent removed from the ratchet-wheel by means of a cam or, as shown in the drawings, a projection 19, carrying a small roller 19, extending from a sleeveton the drivingshaft D. As the said projection 19 revolves around the shaft the roller strikes the lever K, which carries the pawl J forward to enter another recess in the ratchet-wheel. Just before the pawl reaches the end of its movement the screw It strikes the vertical arm of the bellcrank lever L, which throws the detent out of the recess in the wheel. As the roller 13 moves out of engagement with the lever K the spring n draws the pawl back, turning the ratchetwheel and allowing the detent to fall into the next recess to hold the wheel against movement while other operations are performed on the nipples in the disk G.

The usual form of drill-chuck is employed. The trimming-chuck is fiat, with a recess q in one side. 0 is the aperture to admit the nipple, r is the centering bit or cutter to prepare the nipple for the drilling operation, and sis the trimming-cutter, which reduces the diameter of the end of the nipples, as shown in Fig. 11. Both of these cutters are provided with adjusting or set screws to hold them in place in the chuck.
