BICYCLE-TIRE MACHINE.

SPECIFICATION forming part of Letters B a'tent No. 367,721. dated August 2, l857.

Application filed November 26, 1856. Serial No. 219,990. (No model.)

To all whom it 17mg concern:

Be it known that l, VILLIAM A. MCCOOL, a citizen of the United States, residing at Perrysville, Ashland county, State of Ohio, have invented a new and useful Improvement in Bicycle-Tire Machines, of which the following is a specication.

The object of my invention is to provide a machine in which strips of metal are properly bent and formed into tires over a revolving drum or wheel made of the desired size to correspond to the wheel actually used in the bicycle, and adapted to have said drum replaced by other drums of varying sizes, so that one machine is capable of producing any sized bicycle-tires that may be desired. One means of accomplishing this result is shown in the accompanying drawings, in which*A Figure l represents a side view of the 1na chine, the part of the revolving drum which penetrates below the floor not being shown.

Fig. 2 is a top plan.

Similar letters indicate similar parts in both of the iigures.

A is the frame of the machine.

B is the revolving wheel or drum.

G represents the pulleys for driving the machine connected by belting with the source of power. (Not shown.) These pulleys are mounted on the shaft a, the outer end of which is journaled in the grooved arm b and the inner end of which is journaled in the framework.

Upon the shaft a is the pinion c, which gears with the gear-wheel D, mounted upon the shaft d, journaled in the frame-work aud carrying the beveled gear e, which in turn engages the beveled gear E, which is mounted upon the main shaft of the machine, f. This main shaft fis mounted in journal-boxes g y upon the frame of the machine, and carries upon its outer end the drum or wheel B, before mentioned. On the shaft f is a set of pulleys, G, connected by belts with a corresponding set of pulleys, H, upon secondary shaft l1., mounted in journal-boxes i z', secured to the framework of themachine. On the outer end ot this shaft 7L is the pulley l, connected by a belt toa pulley on the shifter J. The object of this shifter J is to move the entering-*die gradually across the surface of the drum B, as hereinafter eX- plained.

Mounted loosely upon av shaft, 71 are the arms K K, which support the entering-die L, through which the rod is fed tothe drum, and which by its inclined surface j holds the rod firmly to Athe surface of the drum to make it take the shape of the drum, and therefore cling to the same during its revolution.

Auxiliary support to the die L is furnished by the arm M, pivoted at 7s to the rod N, the other end of which is pivoted to the frame. work at Z.

The slotted guide O is provided` for enabling this swinging support for the die L, com posed of the arms K K, M, and N, to be raised or lowered to bring it into close contact with the differentsized drums employed. This slotted guide is a grocved piece rigidlysecured at its upper end to the arm K, and provided with a long longitudinal slot moving upon a set screw or pin, m, threaded into the framework of the machine; It is readily seen that by loosening` the grip of this screw m the whole arrangement of the die, with its.

supporting-arms, may be lowered from the position shown in Fig. 1', full lines, to that shown by dotted lines, wlere it is held by turning in the screw; or it may be held at any intermediate division that is desired.

The plate l?, Fig.2, which holds the entering.- die, is constructed as follows: Acentralislot, a,

runs nearly the whole width of this plate P,

and the platform o is mounted over this slot in such a way that when the pulley on the adj nster J revolves this platform is fed along over this slot a away from the pulley. In one corner of this platform are the two rollers p, between which the rod is fed to the drum through the die q and back under the inclined surface j, above mentioned. form o, with the die, rollers, and inclined surA face, has been fed through the fulllength of the slot n, the machine is stopped, the tires that have been formed are removed from the drum B, and the platform 0, Src., are thrown back to their starting-point by the handle and handwheel R.

The operation of the machine may be read ily understood, and is as follows: The end of a long strip of metal capable of making a large number of tires is inserted between the rollers p andthe machine started by the revolution of the pulleys C, which, acting through Vhen the platand thereby the rotation of the druni draws the rest of the rod th rough the die and rollers and winds it around the surface of the drum. By the time the drum has made one revolution the shifter has so changed the position of the entering rollers and die, with their aecompanying devices, that the rod is fed alongside of the tire formed by the first revolution without overlapping. This is continued until the whole rodsurface of the drum is covered with tires, and the machine is then stopped, the tires cut apart and removed from the drum, and the drum replaced. lf desired, the drum,

with its encircling tires, may be removed and a new drum substituted, so that the individual tires may bc removed and sprung into shape as convenience permits.

l. The above-described bicycle-tire maehi ne provided with a revolving` drum for forming the tires, and an entering-die mounted on a vertically-adjustable'support for conveying and shaping the tire to and about said drum.

2. A bicycletire machine provided with a revolving druni capable of forming and holding a large number of tires, an entering-die and its supporting-platform arranged on a Verticallyadjustable frame, and an adjuster arranged and adapted to move said platform and die gradually across the surface of said drum.

8. In a bicycle-tire machine, an adjustable support for holding the entering-die rollers and folding-edge, which consists of the arms M K K, rod N, and slotted arm O, arranged and adjusted substantially as described, and for the purposes speciiied.
