Application filed April 15, 1918. Serial No. 228,686.

To all whom it may concern:

Be it known that I, WILLIAM: N. BOOTH, a citizen of the United States offjAmerica, residing at Detroit, in the county of Wayne and State of Michigan, have invented cer tain new and useful Improvements in Machines for Assembling Spoked -Wheels, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to the manufacture of wheels comprising a series of wooden spokes and wooden felly sections which are pressed into engagement with a metallic rim. It is the object of the present invention to obtain a machine in which the work of assembly is expeditiously and accurately performed and which has various features of advantage as hereinafter set forth.

In the drawings:

Figure 1 is a central section through the machine partly in elevation;

Fig. 2 is a side elevation thereof;

Fig. 3 is a sectional plan View; and

Figs. 4, 5, 6 and 7 are diagrams showing the several steps in the operation of the machine.

A is the frame of a mechanical press, B is the bed or table -therefor, C is a reciprocatory plunger, D a cross head for carrying .the plunger, E pitman rods on opposite sides of the machine for actuating the cross head, F cranks for actuating the pitman rods and G the cranl ,-shaft,all of any suitable construction. Upon the bed B is mounted a frame member H centrally recessed to receive the wheel to be assembled and provided with a series of radial guides H for clamping jaw members I. The latter are preferably positioned to aline with the spokes of the wheel to be assembled and have their inner ends arc-shaped to engage the periphery of the felly. The members I are simultaneously actuated in a radial direction by an intermittently which as shown comprises a. master gearwheel J arranged below the bed, a ser es of pinions K in mesh therewith and a series of shafts L on which said pinions are mounted, passing upward through 7 member H and provided at their upper ends with a cam or eccentric L engaging a trans; versely-slidable bearing block- M in the aw member I.' The arrangement is such that whenever the gear-wheel J is in rotation the pinions K will be simultaneously and correoperating mechanism,

bearings L in the spondingly revolved, effecting a revolution of the shafts L, which in turn, actuating through the medium of the transverselysliding blocks M will actuate the jaw members I radially.

It is essential to the operation of the machine that the jaw members I, after being moved radially inward to clamp the felly and spokes, should dwell in this position during the operation of pressing the felly into the rim. This result is accomplished by providing an intermittently operating mechanism for the gear-wheel J, so timed as to impart to each of the pinions a onelialf revolution and carry the cam or eccentric from its outer to its inner limit of thrust. I preferabl employ a well-known Geneva movement or intermittently actuating the gear-wheel J, and, as shown, N is a star-wheel rotating with the gear-wheel J, having radial slots N therein and concave bearings N in its periphery intermediate said slots. 0 are cranks mounted on vertical shafts O journaled in bearings onopposite sides of the frame, said shafts being actuated through Wheels P P from the mainshaft G. The cranks'O are provided with roller crankpins 0 for fitting within the radial slots N and are further provided with locking segments 0 for engaging the peripheral notches N of the star-wheel. In the operation of this mechanism the continuous rotation of the cranks 0 will cause the roller crank-pins O to engage the radial slots N and actuate the star-wheel N. through a segment equal to the throw of the crank. As

the roller 0 leaves its engagement from the slot N, the segment 0 interlocks with the concave bearingN thereby holding the star-wheel stationary while the crank is passing through one-half a revolution and into engagement with the next succeeding slot N. Thus during the continuous rotation of the crank the star-wheel is ,moving substantially one-half the time and is Sta-- tionary the other half.

Arranged centrally within the recess in the frame member H is a worksu-pporting table or platen Q. This is provided with a shank Q vertically, slidably mounted in a bearin in the bed B and connected by a rod R having a slotted yoke R embracing the shaft G to a iston R in a pneumatic cylinder R. A similar pneumatic cylinder S is mounted upon the cross-head D, the piston S being connected to .a rod Swhich passes centrally through the plunger C. At the lower end of the rod S is a flat bearing head S with a central downwardly-project pm S at the inner end thereof. At the completion of theinward movement the cranks O and roller pinsO are in a position to disengage ,from the star-wheel, whilethe lock- 65 ing segments will engage with notches N,

locking said star-wheel from movement in any direction. During all of the movements thus far described the cranks F are rotating and through the medium of the pitman'rods ing pin S en'gageable with an aperture Q E are actuating the cross-heads D and plunin the platen Q'. The parts are 'so arranged ger C in a downward direction. Suflicient that the pressure upon the pistons S and R clearance is provided between the flange C is in opposite directions so that the work of the head C andthe work, so that all of will be clamped between the plate S and the movements thus far described can take 10 platen Q, but the pressure in the cylinder R place before the flange'C? comes in contact which is of greater diameter, will be in eX- with the felly of the Wheel.- When, however cess of that in the cylinder S, so that the this occurs, the further downward movement parts will normally be heldwith the platen of the plunger will press the telly sections Q in its raised position. out of engagement with the jaws I and into 15 Theplunger C has mounted thereon a engagementpwith the metallic rim which is head C with a depending annulanflange C in registration therewith. Thus without reiforbearing upon the felly of the wheel. leasing the radial clamping pressure the Thus, whenevefthe'cross head D 15 lowered felly sections are foreed into engagement by the operation of the cranks F and pitma-n with the rim.

20 rods E, the head-C and flange C Wlll press 'It is very essential to hold the spokes in the wheel downward a-gain t h .I' l their proper plane during the. movements of the platen Q and the pneumatic pressure above described so as to prevent forming an in the cylinder R. In the complete operaimproperly dished wheel. This is effected tion of the machine the parts are initially 'inby the opposed pressures of the pneumatic 25 the position shown in Fig. 1, where thecylinders R and S, which press the head S platen Q is at the upper limit of Its moveand platen Q a ainst opposite sides of the ment. The operator first places the metallic spoks' with su icient force to hold them wheel rim in' the recess in ,the member-H, straight.- During the downward movement where it will engage the guide bearings H of the plunger 0 the cylinder S is carried 30 for holding it concentric with the axis of the downward therewith, but this will not displunger. The wheel sections are then placed 'tur'b the clamp, for the piston S is free to upon the platen Q, these preferably comprlstravel in the cylinder and the pneumatic ing two semi-circular, felly sections with rapressure against the piston Rbeing in excess dial spokes in enga ement therewith, and the of that against the piston S, the position of 35 position of the wor sup orted on the platen the platen is undisturbed. ,When the flange is such as to bring the elly sections 1n the C comes in contact with the felly-the downplane of the clamping jaws I. Pneumatlc ward mechanical pressure is sufficient to pressure is then supplied to the cylinder S overcome the pneumatic pressure in the cylso as to move the rod S downward carrying inder R so that the platen will be forced 40 the head S into contact with the upper face downward, the same pneumatic clamping of the inner end portions of the spokes, pressure on opposite sides of the spokes bewhile the pin S, which is sli htl tapered, ing maintained. At the completion of the will be forced into engagemen Wit the ends downward movement and when the telly is of the spokes. The operating mechanism for fully engaged with the metallic rim, pneu- 45 the ress is then tripped, which will start the maticv pressure in the cylinder R is exsha G in rotation. During the initial hausted, this being accomplished automatimovement of this shaft the cranks O, which cally or by the manual operation of a relief, are driven through the medium of the bevel valve. As a consequence when the plunger gear-wheels P P and shafts 0, will actuate C and head C are elevated the platen Q will 50 the star-wheel N, thereby rotating the gearremain in its lowered position, but may be wheel J and all of the pinions K in mesh raised to disengage the completed wheel by therewith.
