BAND AND TIRE SETTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 444,547, dated January 13, 1891.

Application filed March 28, 1890. Serial No, 345,789 (No model.)

To all whom it may concern:

Be it known that I, JONATHAN H. SAMUELS, a citizen of the United States, residing at Moline, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Hydrostatic Band and Tire Setters for Vagon-Wheels and other Purposes, of which the following is a specification, reference being had therein to the accompanying drawings, making part of this specification.

The present invention has for its object to provide a band and-tire setting machine operated by hydrostatic pressure against a vertical piston, by which a series of pivoted clamps or encircling sections are made to converge or approach each other in consequence of being forced longitudinally within the interior ofa frustum of a cone.

Figure 1 is a vertical section of my improved band and tire setting machine in complete working order setting one of the middle bands on a wagon-hub. Fig. 2 is a top view of the same parts, except that thehub and center standard are omitted. Fig. 3 is a section of the machine not in operation with the piston down to the lower end of its stroke and the clamps or encircling sections thrown together to receive the band and the hub on which the band is to beset. Fig. at is a section of the operating part-s shown in Fig. 1 in the act of setting one of the end bands on a hub, a few of the minor details being omitted. Fig. 5 is an interior view of one of the series of pivoted clamps or encircling sections as viewed from the center standard. Fig. 6

. is a section, and Fig. 7 a view, of the under side of the annular packing-ring a on an enlarged scale and having a coil-spring u embedded in its fold.

A represents the hub of the wheel on which the. bands are to be set.

B is preferably a frustum of a hollow cone or zone of a sphere.

O is a hydrostatic piston; D, the cylinder surrounding it; E, the base-plate.

F F F F are four vertical standards supporting the part B.

his one of the pivoted converging clamps.

dis a slotted bracket, to which the lower ends of the clamps are pivoted, and is bolted to the upper end of the piston.

j andj are removable steel dies that encircle the band which is being setupon a hub, and are adapted to fit and be fastened in a seat provided for them in the upper ends of the clamps 71, where they are held by the countersunk bolts 7t.

Z is a center standard passing upward" in the center of the hub, and is made firm to the upper end of the piston C, and having a screwthread out upon it.

m is an adjustable plate made to be raised and lowered by means of athread cut through it, so that it can be turned up or down upon the center standard Z to any height necessary to accommodate the different lengths of hubs, and is then made fast by the lock-nut n, Fig. 3.

0 is one of the middle bands of the hub being operated upon, as shown in Fig. 1; r, the end band being set, as shown in Fig. 4.

s is the inlet to the cylinderD, and through which the water or other fluid is to be forced for operating the piston O.

u is an annular packing-ring seated in a groove formed by the packing-ring t and the upper end of the cylinder, as shown.

a is an annular coil-spring embedded in the packing-ring a. The clamp-brackets '6 are each secured to the top of the piston by the cap-screws c and o, as shown in Fig. 1, or may be secured thereto by any other suitable means, or they may, if desirable, be cast integral with the piston itself.

A simple metallic ring cl, Fig. 4, encircling the center screw-standard Z, serves as a hitching device for one end of the coil draw-springs f, which act between said ring and the pivoted clamps to draw them inwardly until their upper ends impinge against each other and form a continuous circle. The object of these coil-springs is to keep the upper ends of the pivoted clamps drawn inwardly as far as they can move, so that an iron band which it is proposed to set upon a hub or rim ofa wheel may be forced down into its seat, as

shown in Figs. 1. and 4:, the rounded upper ends of the clamps causing the pivoted clamps to yield outwardly as the band or tire is pressed down between them, the elastic bearings holding it in position during the process of upsetting it to fit the hub or rim of the wheel.

The object of the toilspring u is to constan'tly crowd the flanges of the packing-ring l the tires on the rims of said wheels.

the packing-ring, consequent upon the first rush of water into the cylinder, is by this coilspring checked or stayed until the full pressure of water is-exerted upon the hollow of the packing-ring.

No force pumping apparatus is shown in the drawings, as almost any of the usual make of force-pumps can be used, there being no peculiarity of pump required with this mal chine. used.

Instead of employing a frustum of a cone, as described in the drawings, a zone of a sphere may be used or any other form that will not interfere with the general functions sought to be accomplished.

Having now sufiiciently illustrated the mechanical features of my said improved hand and tire setting machine, its operation is as follows: The piston (J being down to the lowermost end of the stroke, as shown in Fig. 3 of the drawings, and the pivoted clamps 7t 71, &c., being slightly drawn inwardly at the top ends, so as not to touch the surrounding inclined surface of the hollow cone I the band is then to be forced down into its seat in the'jaws of the clamps, the latter yielding outwardly to receive it. The hub is then to be dropped down over the center standard and rest upon the adjustable plate m. Now the force-pump is set in operation, forcing the water or other fluid into the cylinder through the inlet 5, and the raising of the piston causes the upper ends of the clamps h h 71, &c., to draw inwardly by the converging form of the hollow cone-shaped rim B, thus upsetting or shortening the band to the required size to bind the hub as tightly as desired. As soon as the band is properly set. the force-pump is made to cease working and the water or other fluid, as the case may be, is allowed to escape out of the cylinder through any ordinary stop-valve into a cistern below, the piston having settled down into the cylinder, as before. The hub, with the It preferred, stored pressure can be band properly set, may now be removed and the machine put in readiness to receive another band and hub.

Although the machine as represented in the drawings is seemingly fitted to set bands 011 hubs only on wheels of vehicles, still it is evident that by enlarging the diameter of the machine the same would be equally applicable, and it is my desire to use it for setting In order to accommodate the same machine to setting bands of different sizes within certain limits, I have provided the pivoted clamps h h, 850., with removable steel dies or jaws of different thicknesses, as shown atj, Fig. 1, and j, Fig. l, the purpose being to extend inwardly a little farther or not so far, as the case may be, to accommodate different diameters of bands. In the drawings I have shown and illustrated six of these pivoted clamps h; but, inasmuch as the same result may be substantially accomplished with some other number, I do not wish to be limited by that exact number. I have chosen. that number merely from preference.

It will be seen that by myplan of construction the middle bands may be set upon a hub so as to be a little smaller of diameter on the side next to the spokes, thereby offering additional resistance against their coming off when the hub has become thoroughly seasoned and shrunken, and in like manner also the end bands on the hub can be slightly contracted on the inner side of the band as a further security against slipping off.

I claim- 1. In a band'and tire setting machine, the combination of a series of pivoted clamps h 72 7a, consisting of two or more such clamps, the hydrostatic piston O, and the converging or cone-shaped ring B, substantially as and for the purpose set forth.

2. In a band and tire setting machine, the combination of the piston 0, center standard Z, and pivoted clamps h h 71, substantially as and for the purpose set forth.

3. In a band and tire setting machine, the combination of the center standard I, adj ust able plate at, lock-nut 'n, pivoted clamps h h h, and movable dies j, substantially as described.

4-. In a band and tire setting machine, the combination of the pull-springs f, annular ring (Z, and pivoted clamps 71 as and for the purposes set forth.

5. In a band and tire setting machine, the combination of the annular packing-ring 'u, and the inclosed coil-spring to, as and for the purposes set forth.
