RUBBER-TlRE-SETTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 697,056, dated April 8, 1902.

Application filed October 14, 1901. Serial No. 78,824. (No model.)

To aZZ whom, it may concern: 1

Be it known that 1, JOHN K. WILLIAMS, a citizen of the United Statesn'esidin g at Akron, in the county of Summit and State of Ohio, have invented a certain new and useful Improvement in Rubber-Tire-Setting Machines, of which the following is a specification.

My invention has relation to improvements in machines for lacin or settin solid.

rubber vehicle-tires in channeled metallic tires.

The object of my invention is to produce a new and improved machine of the class named in which the line of draft of the wires shall be between the clamping-arms and which shall be simple in construction, efficient in operation, and in which the number of parts shall be reduced to a minimum.

To the aforesaid object my invention consists in the peculiar and novel construction, arrangement, and combination of parts hereinafter described, and then specifically pointed out in the claims, reference being had to the accompanying drawings, forming a part of this specification.

In the accompanying drawings, in which similar reference-numerals indicate like parts in the different figures, Figure 1 is a front elevation; Fig. 2, a section at the line 00; Fig. 3, a section at the line y; Fig. 4, a rear elevation; Fig. 5, a section at the line a, and Fig.

. 6 a view of the winding-crank and pinion.

7 Referring to the figures, 1 is a metallic casting of the general form shown, being a plate with a lateral extension to permit of its being bolted for support to a post 2. In the lower edge is an upwardly-extended curved notch 3, for a purpose to be stated, from one side of which depends an arm 4, from the front face of which extends an integral horizontal foot 5, having near its outer end a screw-threaded opening in which runs a screw 6, provided at its lower end with a hand-wheel 7, by which it may be turned, and at the top a freelymounted cap 8, having a curved top to adj ustably support a wheel-felly 9 during the process of setting the rubber tire.

The cap 8 has a rearwardly-projecting blade 10, the outer end of which runs freely in a vertical channel 11 in the arm 4,and thus holds the cap against turning with the screw.

In the lower front face of the plate 1, on opposite sides of the notch 3, are pivots 12 13, screw-threaded at the outer ends, on which are freely mounted the wire-clamps 14, between which extends a connecting-bar 15, the

ends of which are perforated and fit on the pivots 12 13 and are retained by the nuts 16 17.

Each wire-cla1np consists of an inner bar 18, that rests against the plate 1, and an outer jaw 19, having pivotally mounted in a notch in its upper end a handle-cam 20, arranged to bear against the bar 18 and when the handle of the cam is rocked down to force the lower end of the jaw 19 toward the lower end of the bar 18.

Between the lower ends of the bar 18 and jaw 19 and supported by the pivot 12 or 13 is an intermediate plate 21 of like width.

The outer lower ends of the bar 18 and jaw 19 are reduced toward their inner faces, and the adjacent faces of these parts and the plate have corresponding oppositely-disposed grooves to grasp the tire-wires.

To the upper ends of each of the bars 18 is pivotally connected one end of a flat link bar 22, their opposite ends being freely mounted on a screw 23, having a hand-wheel which passes through a slot 24 in the plate 1 and en ters a nut 25 at the back of the plate 1.

By raising or lowering the screw 23 in the slot 24 the wire-clamps can be brought pew pendicular to the tangent of the wheel-rim and locked at any desired point, thus adapting the machineto wheels of different dian1- eter.

Through the plate 1 are bored two holes to receive winding-shafts 26 27, having bosses at each end.

Back of the plate 1 0n the shafts 26 27 are splined-like gear-wheels 28 29, respectively, provided with pawls 3O 31, respectively. The shafts 26 27 are free to slide lengthwise in their openings and are held until it is desired to draw them backward by a plate 32, retained to the pivot-shaft of the pawl 29 by a set screw 33.

In the front end of each shaft 26 27 is a notch like those in a screw-head, in which to place the wires for winding.

In the back of the plate 1 are three like socket-holes, the upper and lower, 34 and 35, respectively, shown in Fig. 4, the central one being obscured by the pinion. Each hole has bosses at the rear of the plate to give additional bearing length, similar to those about the holes for the shafts 26 27. A shaft 36 is fitted to accurately enter these holes and has at its outer end a crank arm and handle and bears a pinion 37, adapted to mesh in the gears 28 29.

In operation the rubber tire 38, with the wires 39 4O inclosed, is placed about the wheel in the channeled metallic tire and secured at one end in the right wire-clamp 14. The opposite ends of the wires are then brought between the members of the left wire-clamp 14 and the end of one, 39, placed in the notchin the shaft 27, and the other is brought under the shaft 27 and up into the notch in the shaft 26. The crank-shaft is then placed in one of the holes 34 35, and for the purpose of illustration it will be assumed in 34, and the wheel 28 and shaft 26 turned, winding the wire on the front end of the shaft until it is tight. The operation is then repeated with the wheel 29 until the wire 39 is drawn correspondingly tight by the shaft 27, the gears 28 29 being held by the pawls 3O 31. The crank-shaft 36 is then placed in the intermediate socket-hole, with the pinion 3'7 meshing in both gears 28 29 and turned simultaneously,

winding the wires on both shafts 26 27 until the required tension is secured. In this operation the wire coils close to the boss on the face of the plate 1 in a spiral, forcing or drawing the shaft on which it is winding to the front, and thus always causing the wire to draw in the same relative position. The left wire-clamp 14 is then tightened on the wires and the wires out between the clamps 14 at suitable distances for forming a joint, the notch 3 permitting a file or like tool to pass for that purpose. The shafts 26 27 are then pushed into the plate 1 until their ends are flush with the face of the bosses, thus removing them out of the way of the workman in making the joint and stripping the coiled wire off from the shafts. The ends of the wires are then brazed together, the clamps 14 released, and the wheel removed to have the ends of the rubber brought together in any approved manner.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-- I 1.
