TIRE BOLTER AND CUTTER.

SPECIFICATION forming part of Letters Patent No. 388,778, dated August 28, 1888. Application filed May 10,1988. Serial No. 273,396. (No model.)

To aZZ whom it may concern.-

Be it known that .l, XVILLIAM A. JOHNSON, a citizen of the United States, residing at Aurora, in the county of Kane and State of Illinois, have invented new and useful Improvements in Tire-Bolters and Gutters,of which the following is a specification.

My invention relates to an improvement in machines for bolting the tires to vehiclewheels and cutting the projecting ends of the tire-bolt; and it consists in the peculiar construction and combination of devices that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a tire-bolter and cuttinginaehine embodying my improvement. Fig. 2 is a similar view of the opposite side of the same. Fig. 3 is a top plan view. Fig. 4. is a front elevation.

A represents abasc-plate, which is adapted to be bolted to a suitable bench or horse on the upper side thereof, and is provided with a pair of vertical standards, 13. To one end of the 2 5 base-plate is bolted a sigmoidalshaped arm,O, which extends forward and laterally therefrom.

D represents a pair of rearwarddiverging arms, which extend from the rear side of one 0 of the standards B, at a suitable distance above the base-plate, and connecting the rear ends of the said arms is a loop or keeper, E.

F represents a shaft, which is journaled in openings near the lower ends of the standards 5 B, and is arranged in a horizontal plane. The outer or front end of the said shaft is tapered and squared, as at G, to enable the same to be secured in the socket of an ordinary bit-stock, such as are employed by carpenters, wheel- 0 Wrights, and other workers in wood,andwhereby the shaft F may be rotated, as will be readily understood.

A spur-wheel, H, is arranged between the standards B, and is feathered or splined on 5 the shaft F, so that the latter is free to slide longitudinally in its bearings and through the wheel H. To the rear end of the shaft F is swiveled a socket or head, which is formed on the front end of a rack-bar, I, that is arranged in the lower end of the loop or keeper E.

K represents a shaft, which is similar to the shaft F and is shorter than the same, and is jonrnaled in openings near the upper ends of standards B. On this shaft K is feathered or splined a wheel, L, which is arranged between the standards 13, the said shaft K being adapted thereby to slide longitudinally through said standards and through said wheel. The front end of the shaft K is provided with a movable head, M, that is seen red thereto by a set-screw, N, and has a socket, O, in its front end adapted to receive a nut to be applied to the spindle of a tire-bolt. To the rear end of the said shaft K is swiveled a socketcd head for the rack-bar P, which is ar- 6 ranged in the upper end of the guide orloop E.

R represents an idle-whecl, which is journaled in the loop or keeper 1? and engages the rack-bars, and is thereby adapted to cornmunicate longitudinal motion from one shaft to the other.

On the outer end of the arm C is pivoted the lower end of a link, S, which has its upper end provided with a pair of cars, T, and has a recess, U, in its front side, at its upper end, in which recess is arranged a lower cutting jaw or blade, V, the upper edge of which is beveled on opposite sides, the said jaw or blade being held into position in the link by a set-screw, W.

X represents a lever-arm, which is pivoted at its lower end, between the ears T, on a bolt,

Y, and has a handle, Z, at its outer end. At the lower end of the arm X is formed a shoulder or abutment, A, which is adapted to be en- 8 gaged by the head of an adjustable stop or bolt, B, which is screwed to the upper end of the link, so as to limit the motion of the arm X. A cutting jaw or blade, 0, is secured to the outer side of the arm X, and is similar to the lower jaw or blade, V.

The operation of mylnvention is as follows:

' The vehicle-wheel is journaled temporarily on a vertical spindle, a, that projects from the upper side of the bench or horse, so that the said wheel is disposed in a horizontal plane and is adapted to be rotated. My improved machine projects up between two spokes of the wheel, with the shaft K on the level of the tire-bolt. of the tire-bolt by hand until the nut is started, and the operator then attaches a bit-stock to A nut is applied to the inner end 1C0 the outer end of the lower shaft, presses inward against the same so as to cause said shaft, by reason of the rack-bars and the idle gearwheel, to force the upper shaft outward until the socket-head of the latter receives the nut, and the operator then rotates the lower shaft by means of the bit-stock, and consequently imparts rotary motion to the upper shaft by reason of the gear-wheels, before described,

which connect the said shaft, and thereby drives the nut home on the bolt, as will be readily understood. Having secured the bolt, the operator then draws outwardly on the lower shaft, so as to cause the upper shaft to move inward from and disengage the nut, the wheel is partly turned so as to bring the bolt in the same vertical plane with the link, and the handle-leverX is then grasped and swung upward and turned on its pivoted bolt, so as to cause the cutting-blades to open and receive the projecting ends of the bolt between them, and the operator then draws outward on the upper end of the handle-lever, and con sequently exerts such leverage on the cutting blades or jaws as to cause the same to completely sever the projecting end of the bolt.

Having thus described my invention, I c1aim- 1. The combination, in a machine for bolting tires, of the frame, the two shafts sliding longitudinally therein and oppositelymovable, and gearing between the same to impart a rotary motion from one to the other, one of said shafts having a socket adapted to receive the nut of a bolt, substantially as described.

2. The combination of the base or frame having the standards 13, the shafts F K, journaled in said standards and movable longitudinally in their bearings, said shafts having the rackbars, and one of said shafts being provided with the socketed head, for the purposeset forth, the gear-wheel journaled in a suitable support and meshing with the rack-bars, and,

the gear-Wheels feathered or splined on the shafts and meshing with each other, substantially as described.

3. The combination of the frame or base,the link S, having one end pivotally connected to the frame and the other provided with a cutting jaw or blade and an adjustable stop, and the lever X, pivoted to the free end of the link and having a cuttingjaw or blade, substantially as described.

4. The combination of the base plate or frame, the link S, pivoted or hinged thereto and having the adjustable stop D on one side and the cutting jaw or blade V on the opposite side at its free end, and the lever X, pivoted to the free end of the link, adapted to be engaged by the adjusting stop or bolt, and having the cutting blade or jaw 0, adapted to operate in conjunction with the blade V,-

substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

WILLIAM A. JOHNSON.
