SWAGING- MACHINE.

SPECIFICATION forming part of Letters Patent No. 585,151, dated June 22, 1897.

Application filed May 14,1896. Serial No. 591,455. No model.)

To all whom, it may concern.-

Be it known that I, J OHN T. KENNEDY, a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Swaging Hachinery, of which the following, when taken in connection with the drawings accompanying and forming a part hereof, is a full and complete description,sufficient to enable those who understand the art. to make and use the same.

The invention relates to machines designed to swage a portion of the length of a spoke composed of wire for bicycles or carriages. Such machines may of course be used to swage other materials, as tubes, wires for other purposes, and the like.

In the accompanying drawings, composed of two sheets, Figure 1 is a plan view of a swaging-machine embodying my invention. Fig. 2 is a sectional view of such machine on line 2 2 of Fig. 1, Viewedin the direction indicated by the arrows; Fig. 3, a sectional View on line 3 3 of Fig. 1, viewed in the direction indicated by the arrows; Fig. 4, an enlarged View of the gripping mechanism of the machine; Fig. 5, a rear elevation of a cam forming an element in the mechanism illustrated in Fig. 4; Fig. 6, an elevation of the lever and nut thereon engaging with the revolving screw, (shown in cross-section,) by means of which the spoke is drawn through the swaging-dies of the machine; Fig. 7, an elevation of engaging gear-wheels by means of which the rotation of the spoke as it is drawn through the swaging-dies is effected and controlled with relation to its longitudinal movement; and Fig. 8, a sectional view on line 8 8 of Fig. 1, viewed in the direction indicated by the arrows.

A letter of reference applied to a given part is used to designate such part throughout the several figures of the drawings wherever the same appears.

A is the base of the machine.

a a are uprights secured to base A.

B is the driving-shaft of the machine, rotatably mounted in j ournal-bearings C C on uprights a a, respectively.

D is an eccentric on driving-shaft B.

.E F are levers forming what is termed a knuckle-joint, and G is a link connecting the coupling II of levers E F and the eccentric D on shaft B. The rotation of the shaft B is thus made to produce reciprocatory rectilinear movement of coupling H.

I is a stationary head between uprights a a, and J is a recess in the lower side of head I, suitably journaled to receive the upper end of lever E. For reasons about to be given I desire to make the head I vertically adjust-v able, and this is effected by interposing wedge K between head I and cross-bar L, such crossbar being rigidly secured to uprights o; a. To maintain head I in its adjusted position, I use set-screws M N.

O is an adjusting set screw extending through lip or lug P on wedge K and against the face of cross-bar L.

Q is a swaging-die firmly secured to base A, as by screws q q.

R is a swaging-die vertically movable between uprights a a on guides S S.

T is a shaft extending through die R and through the lower end of lever F, such shaft being journaled in lever F or die R (or both of them) and connecting them together.

Lever E being journaled to block I and levers E F being coupled together and to connecting-bar G, with such connecting-bar G on eccentric D on shaft B, the rotation of the driving-shaft B produces a vertical movement of the die R, and die R can be (and is) so adjusted with reference to die Q by means of wedge K, as hereinbefore described, that a wire spoke or other article placed between the dies is properly swaged by the movement of die R.

- I will now proceed to describe the mechanisms by means of which the spoke or other article being swaged is moved longitudinally between the dies Q R to determine the place and amount of swaging thereof.

A is a journal-bearing secured on base A, and B is a shaft rotatably mounted in such journal-bearing. Shaft B can also move longitudinally in j ournal-bearing A.

C is a journal-bearing through which the shaft B extends and in which it is rotatable.

D D are collars rigidly secured on shaft B on each side of the journal-bearing C to prevent longitudinal movement of shaft B in such journal. It occurs, therefore, that when it is desired to move shaft B longitudinally in the journal-bearing A it is merely necessary that journal-bearing C be correspondingly moved. So that such journal-bearing C may at all times constitute the proper and desired support for shaft B, I place the dovetailed part E of such bearing 0 in groove F in base A.

G is a lever pivotally mounted on journalbearing 0 by pin II.

I is a half-nut on one end of lever G, engaging with the screw-threads on rotatable screw-shaft J.

K is a gear-wheel rigidly secured on shaft J and engaging with gear L on shaft B. Shaft J is rotatably journaled in journalsj M is a driving-pulley secured to gear-wheel L.

\Vheels L M are mounted loosely on shaft B, so that such shaft may move longitudinally through the hubs thereof, but with feather b interposed between such hubs and the shaft, so that such wheels will be rotated by the shaft.

0 is a pulley on driving-shaft B, and P is a belt or cord extending over pulley O, idlers Q and R, and pulley M.

S is the standard, secured to base A, on which idlers Q R are rotatably mounted. Shaft B and screw-shaft J are thus rotated by driving-shaft B through pulley O, belt P, pulley M, feather Z), and gears K L. \Vhen lever G is in position so that half-nut I is in engagement with screw-shaft J, the shaft B (through journal-bearing C) is moved longitudinally away from dies Q R. So that the longitudinal movement of shaft B away from dies Q R shall rotate and at the same time draw through such dies the wire X or other material I mount gripping-jaws T T, connected by tie U, on the end of such shaft adjacent to such dies and arrange such grippingjaws to properly grasp such wire or other material.

A is a sleeve longitudinally movable on shaft B and fitting between the rear end of gripping-jaws T T at its forward and beveled end.

B is a spring mounted on shaft B, so that its rear end shall thrust against bearing C and its forward end against sleeve U, thus tending to force the sleeve between the jaws T T and so force such jaws upon the wire spoke or other material between them, such jaws T T turning on pivots C C D is a spring tending to turn the jaws T T on pivots C C and so hold the jaws open when the sleeve A is forced back against the spring B E is a rod, one end whereof is mounted in journal-bearing O and the other end whereof projects beyond the front of the machine and has thereon handle F The rod E can be partially turned by the handle F. G is a cam rigidly secured to rod E Cam G2 has cam II on the rear face thereof with which the circular flange I on sleeve A engages by being forced against it by spring 13". J is a peripheral cam also secured on shaft E Cam J is in engagement with lever G, (see Fig. 6,) that is, lever G is held against peripheral cam J by spring K (See Figs. 2 and 3.)

L is the drivingwheel of the machine, loosely mounted 011 shaft B, and M is a clutch arranged to be forced into and moved out of contact with wheel L I of course make no claim for the particular form of clutch employed.

\Vhatever clutch is employed the construction and arrangement thereof should be such as will obtain an automatic stopping of the machine when the proper part of the spoke to be swaged has been extended through between the dies. In order to explain the mechanism by which I obtain the automatic stopping of the machine, a brief description of the clutch is given.

N is a bolt longitudinally movable in groove 0 in shaft B, and P is a spring tending to force bolt N into engagement with aperture Q in drivingwheel L The rear end of spring P is against annular flange R on shaft B.

S is a beveled cut in bolt N Clutch M is movable in guides on m and is yieldingly forced forward into engagement with the beveled edge of cut S in bolt N by spring T U is a cord extending from clutch or fork M over the pulleys a 11?, and W is a hook on the end of cord U which can be engaged with the spoke X when spring P is retracted, so that clutch or fork )1 is released from engagement with bolt N lVhen the machine is started, the hook is put over spoke X, between guides Y Y and the machine will continue to run until the spoke passes on, so that such spoke goes out from under such hook \V Spring I then forcesthe clutch or fork M up into the path of pin N and as such pin is rotated against the clutch or fork the beveled edge of the cut S in the bolt coming against the inclined or beveled edge of the clutch or fork M such bolt is withdrawn from engagement with driving-wheel L and the machine stops.

To be sure that the machine will stop, so that the dies Q R are separated to permit the spoke to be inserted between them and into the gripping-jaws T T, I pivotally mount the pawl A on pivot B connect pawl 13 by connection 0" with abutment D and put abutment E on ring F Abutment D is rigidly secured to clutch or form M so that when the clutch is retracted from engagement with bolt N the pawl A is retracted from engagement with abutment E and when such clutch or fork M is in engagement with such bolt N the pawl A is in the path of such abutment E and will arrest such abutment (and so the machine) when the abutment is brought in contact therewith.

The operation of the machine is: Handle F is grasped and turned so as to disengage nut or half-nut I from the screw-threaded shaft J by means of peripheral cam J 2 and brought forward, thereby bringing forward the journal-bearing O, shaft B, and gripping-jaws T Handle F is turned so as to open gripping-jaws T T by cam H forcing sleeve A through peripheral flange 1 against spring B and out of the rear end of jaws T T. 'A wire spoke is then inserted between dies Q R and into position between gripping-jaws T '1" and handle F turned so as to release cam G from flange 1 thereby permitting spring B to force sleeve A between the rear end of such jaws T T, and also releasing "peripheral cam J from lever G, permitting spring K to raise the end of the lever G in contact with the peripheral cam J thus forcing nut or half nut into engagement with the screwthreads on screw-shaft J. Driving-wheel L rotates continuously while the machine is being operated. Clutch M is forced into engagement with driving-wheel L and the machine is started. The revolution of shaft B produces continuous and rapid vibratory movement of die R on die Q and the interposed spoke X. Pulley M is rotated by belt or cord P, extending thereover and over pulley O on shaft B, and consequent rotation of shaft B, gripping-jaws T T, and spoke X is produced. Gear-wheel L on pulley M rotates gear K, and gear K being rigidly secured to screw-shaft J such shaft is thereby rotated, thus moving nut or half-nut I away from the dies Q R. Nut 1 being mounted on lever G and such lever secured to journalbearing 0 the movement of the nut I produces longitudinal movement of the shaft B away from the dies Q R, thus drawing the spoke X longitudinally through between the dies as they vibrate and at the same time rotating the spoke. As the spoke passes out from guidesY Y hook W is released, as hereinbefore described, and the machine stopped. Handle F is again turned slightly, brought forward, the spoke which has been swaged released, and the operation repeated with another spoke.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
