ARTHUR J. MORSE, OF SALISBURY, CONNECTICUT, ASSIGNOR TO THE MORSF-KEEFER CYCLE SUPPLY COMPANY, OF SAME PLACE. A

SLOTTING AND SLABBING MACHINE.

SPECIFICATION forming part ofA Letters Patent No. 628,410, dated July 4, 1899.

Application led August 10, 1897. `Serial No. 647,746. (No model.) a

To all whom. t may concern.'

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 Slotting and Slabbing Machines, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to slotting and slabbing machines for use in manufacturing nipples for bicycle-spokes or other similar devices; and the object is to provide a machine that will operate on several nipples or other articles at once, producing a somewhat different operation on each, and that will operate upon said nipples successively.`

, To this end my invention consists in theA combination, in a nipple-slabbing machine, of

a disk provided with chambers to hold the nipples, means to rotate the disk intermit-` tently, a sliding bar carrying a rotatable spindle on one .end extending parallel with a face of the disk, two sets of cutters on the spindle to operate simultaneously on a pair of nipples, and suitable means to reciprocate the sliding bar; and my invention consists in certain other 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 l is the top plan view of my invention. Fig. 2 is the front side elevation. Fig. 3 is the rear side elevation. Fig. l is an end elevation looking from right to left of Fig. l.- Fig. 5 is an end view of some of the important movable parts in the opposite position from that indicated in Fig. 4. Fig. 6 is an end View of the machine, looking from left to right of Figs, l and 2. Fig. 7 is a side elevation of the spindle or spindles carrying the slabbing-cutters. Fig. S is a section of the presser-plate which holds the nipples in the disk, and Fig. 9 shows a nipple before and after it is slabbed.

Referring specifically to the drawings, A is the frame of the machine, having forward extensions aand a for the sliding bar B to move on and rearward extensions b b for the sliding bar C to move on. Another pair of extensions c c and c" are above the extensions h and b to provide bearings for the drivingshaft D, which carries a cam-wheel D' to move the sliding bar C below it, and a cog-wheel E, which meshes with a cog-,wheel E on a short shaft F, turning in bearings over the center of the frame A. The shafts D and F are parallel with each other and lie with their axes in the same horizontal plane. The shaft F also carries a camavheel F', which engages a roller B on the inside of the sliding bar B t-o move the bar toward the disk G, which carries thenipples to be and in the process of being slabbed and slotted.

The disk G is secured on one end of a horizontal shaft G, which turns in bearings g g in a bracket G", secured to the front side of the frame A.

D is the driving-wheel on the shaft D.

The cam-wheel F' is designed to move the bar B longitudinally toward the disk G once during each revolution, and a coil-spring d, connected between the said bar and the extension, serves to retract the bar or draw it away from the disk. The disk G is provided with a circular series of holes which extend through it near its periphery to hold the nipples. 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 have the appearance of rivets, and are countersunk slightly to partly receive the heads. In order to hold the nipples in and to prevent them from turning while they are being operated upon, I provide a bracket H, having a curved arm secured by screws to a segment of a disk h, which carries a curved tension-plate h on the side next the disk in' the path of the heads of the nipples. The tension-plate 72. is curved outward at the receiving end to allow the heads to pass easily between it and the disk. The construction of this segment h is shown clearly in Fig. 8 of the drawings. This view shows the plate h held in a groove in the segment h by apair of curved strips h" 7L", screwed to the segment. A curved plate t' is in the bottom of the groove to form a bearing for the ends of a series of adj Listing-screws 7l' rbc., which pass through the segment to increase the tenthe plate 7L and the plate i. The bracket I-I extends horizontally and lies against the'rear side of the frame Aand is adjustable toward and from the disk G by means of screwsgl j, passing through short slots in the bracket.

The nipples are inserted by hand .in the disk, which revolves in the direction of the arrow. (Shown in Fig. 6.) When-a nipple reaches a point forty-five degrees above a horizontal plane extending through the axis of the shaft G, it is slabbed or made flat on a portion of two opposite sides, after which it is carried by the disk a distance of ninety degrees, during which it is turned over onefourth, allowing cutters mounted on the same spindle as the other cutters to slab or flatten the other two sides, thus forming a square section on the shank of the nipple for the application of a Wrench when it is turned on a spoke. the disk about fifty degrees, more or less, farther it is then in position to have its head slotted or recessed for receiving a screwdriver, as usual, and when it has been carried a few degrees fartherit is pushed out of the disk by a pusher L automatically with the other operations.

A brief description of the operations has been given before the parts have been fully specifically described to prepare for a clear understanding of the operation of said parts, which will be hereinafter fully described.

The end of the sliding bar B nearest the disk is made broad and is provided with a pair of bearings c k for the spindle I of the slabbing-cutters I I, which are arranged in pairs for the purpose of slabbing two sides at once. The cutters are of the usual formnamely, disks with serrated peri pheries--and they are suitably mounted to turn with the spindle, and they are separated to allow the ends of the Anipples to pass between them.

I is a pulley in the center of the spindle and between the bearings k 7c for the beltv which drives the spindle. The cutters I I rotate continuously, and when the disk is stationary the cutters aremade to approach the disk and slab two sides of a pair of nipples. Then the bar B, carrying the cutters, is retracted by the spring d, after which the disk is revolved the distance between two nipples, which brings two other nipples in position to be slabbed, when the bar and cutters are forced toward thedisk as before. The spindle for the cutters is divided in the center, so that one or the other end may be removed without removing the other. The inner ends of the spindle are lapped over each other with' a flat bar Z between, which bar extends diametrically through the pulley, as shown in Fig. 7 of the drawings. I do not limit myself to this form of connection, however, as it may be made in various ways. The spindles are held in place and in' their bearings by angular arms m m, secured to the bar and extending outward opposite the ends of the spindles, and ad justing-scrcws fm' 011/, passing After the same nipple is carried by through the ends of the arms and bearing with their ends on the ends of the spindle I', as shown clearly in Fig. l of the drawings.

.The shaft G is rotated intermittently by means of a ratchet-wheel J on he end opposite that carrying the disk G.- The ratchetwheel is 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 of the ratchet-wheel are shown square and are preferably made square in order that the disk may be held positively against movement in either direction during the slabbing and slotting operations.

J is the pawl for turning the ratchet-wheel.

Said pawl is connected at one end with an upwardly-extending arm of a bell-crank lever K, pivoted to the frame. The pawl J is adj ustable universally in a vertical plane by slots and screws. (Not necessary to be specified.) The other arm of the bell-crank lever is connected by a coil-spring n with the base of the machine to carry the pawl longitudinally when released.

The pawl J is operated to turn the ratchetwheel by means of a roller t, carried on a short arm or projection 7o, extending from a sleeve 7.2" on the drivingshaft,striking during each revolution ofthe shaft the upwardlyextending arm of the lever K. A stop-screw '0 is shown extending through the frame'to engage 'the horizontal arm of the lever K and ver too far. Another cam p on the sleeve operates a pawl or detentp, pivoted intermediate its length,which holds the ratchet-wheel against'movement during each operation by means of a square lug on its free end entering the square recesses in the ratchet-wheel J. The pawl p is seated by a spring p".

M is the spindle, carrying the single cutter N on one end for slotting the 1heads of the nipples after they have been slabbed. This spindle turns in bearings q q'on the broad end of the sliding bar C before referred to. The cutter N is on the opposite side of the disk from the slabbing-cutters.

Q is the pulley on the spindle M for driving the spindle. The head of a nipple is slotted while two other nipples are being slabbed and, of course,while the disk is stationary. Therefore the sliding bars B and C are moved by their cams simultaneously in opposite directions, the disk only turning when the said bars are receding from it. A bifurcated spring-plate N is secured on the end of the bracket I-Ito bear upon the head of the nipple while it is being' slotted by the cutter N to hold it stationary, as clearly shown in Figs. 3 and 6 of the drawings.

The pusher L (shown in Fig. 2 of the draw-` IOO IIO

adapted to strike the end of a nipple and push it out of its aperture in the disk.

I do not wish to be limited to the precise construction of parts shown, as it will be obvious that they may be changed Widely Without departing from my invention.
