.To, dllwwhofir it concern:

- StateofiIowa, have. invented certain Improvements in Machines for Securing Spokes in WheeLHubs, of 'which the following is a s'pecification'.

. There is now known-in the art a class of metal wheels in which the spokes are secured by inserting theiri-nner ends through mortises into the central opening of ahlib, and then upsetting them to head their inner ends and also -form' collars or enlargements at the outer surfaceof the hub. I v v My machine is intended to perform this upsetting operation rapidly and with. uniform results. v

In the'accompanying drawings, Figure 1 is a side elevation of the machine with aportion 'of the main gearwheel atdnesser-nnvmg rod-broken awayto expose other parts to view. Fig. 2 is a top plan view of the same. Fig. 3

- is an elevation of the spoke-clamping devices.

Figs. 4, 5,'a'nd 6 are elevations showing-modifications in the header-driving devices.- 7 and 8 are detail views. 1 I

The machine embraces as its principal parts a device to sustain and adjust the hub, avibratory header acting within the hub t0 encured to a slide, B, mounted on a 'guid'efB. Theslide is sustained by a lifting-spring, 13,-

B is an annular and connected by a pitman, B, to a foot;lever, 13 by which'it may be depressed at the will of the attendant in order to lower the support B and the 'hub therei'n in properrelation to'the heading devices.

I connect thesupport B to the slide byhorizont'al sliding rods B, one of which is pro? vided with a spring, 13*, urging it backward,

A sliding The jawH is jointed at its lower \Vhen the rod Kmoves rearward,it causes the pitman to approximate a position at right angles thereto, and in so doing to close the clamp. The rearward movement of the rod to close the aws is initiated by an angular footlever, K, pivoted to the frame and jointed to the collar which carries the pitman, as shown in Fig. 3. The action is completed, however, and the jaws forcibly closed by a cam-wheel, L, fixed on the main shaft and acting on-a roller in the end of rod K. Apin, K, on the rod K enters an opening in the rear end ofa lever, K pivoted on the frame and connected with the driving-clutch D to throw the same out of action. The opening has its forward side oblique to' the axis of the rod K, so that when the rod is moved by the foot-lever to close the spokeclamp the pin actuates the le-' ver and engages the clutch, thus bringing into act-ion the cam to hold the clamp and also the eccentric to operate the header. The opening is of such size as to allow considerableplay of the pin therein and at the rear side its edge is inclined laterally that .it may actuate the lever and disengage the clutch at the proper time.

The action ofthe machine is as follows: The clutch being disengaged, the clamp open, and the hub-support and heading-tool retracted, the hub is seated in an upright position in the support B. A spoke is then inserted at one end through the hole or mortise in the hub until its extremity extends into the central opening. The foot-lever B is then actuated to lower the support and the hub until the spoke enters the clamp outside of the hub and presents its inner end opposite the header 0,

as shown in Fig. 7. The foot-lever K is then actuated,-closing the clamp and bringing into play the clamp-confining cam and the header operating eccentric. While the clamp holdsthe spoke immovabl y in place, the header advances, first upsetting and enlarging the end within the hub and then carrying the hub forward toward the outer end of the spoke, so that the metal is upset and enlarged between the outer surface of the hub and the inner face of the clamp, as shown in Fig. 8. At the completion of the operation the header is retracted by the eccentric; but before it moves any considerable distance the cam, which is made of irregular form, releases the rod K and permits the spring to open the clamp,thus releasing the spoke, so that the header may not, when used in'a hub with a small axle-hole, pull the hub from the end of the spoke. At the proper time the camvallows the rod to retreat until its pin throws the driving-clutch out of action.

When the machine is required to operate on very heavy spokes, I recommend the adoption of devices such as shown in Figs. 4, 5, and 6 to operate the heading-tool, as they are better adapted than those before described to withstand heavy strains. In Fig. 4 the cccentrio-rod is connected to one end of a lever, M,

middle, connected at its upper end to the 00- centric-rod, and connected at its lower end by an adjust-able pivot'to the rod which operates the header-arm. In this instance the header carrying arm is fulcrumed near the headingtool.

In Fig.6 the lever M is fulerumed, as inthe previous example, near the heading-tool, and is jointed at its lower end adjustably to the eccentriorod. In each case the header-arm is slotted to admit of the operating-arm being adjusted, in order to change the length of movement of the heading-tool. NVhcn operating on iron of large diameter, the tool requires a longer movement than when operating on smaller metal.

Having thus described my invention, what I claim is- 1. In a spoke-fastening machine, a spokeholding clamp, in combination with the pivoted header-carrying arm, the eccentric, the rod connecting the eccentric and arm, and the yielding hub-support.

2. In a spoke-fastening mechanism, the pivoted arm providedrwith a heading-tool to enter a hub, in combination with an eccentric and a connecting-rod mounted at one end around the eccentric and pivoted at the other end to the header-carrying arm, as shown.

3. In a spoke-fastening machine, in combibination with a heading-tool to enter the hub,

the hub-sustaining device, in combination with a supporting spring and a depressinglever.

4. In combination with the vibratory headingtool, the hub'support, the vertically-sliding head having a horizontal sliding connection with the support, the spring to retract the support, the spring to lift the head, and the lever to depress the same.

5. In combination with the connected clamp- I to levers, their operatingpitman, the reciprocating rod connected to the latter, its actuating.- cam, and the retracting-spring.

6. In a spokefastening machine, the clamping-levers, their actuating-pitman, the reciprocating rod, the lever for starting said rod, its actuating-cam, the cam-driving clutch, and the elutchcontrol1ing lever operated by the rod, as shown, whereby the initial closing .of the jaws is caused to set the cam in motion.
