Application filed August 8, 1906. 'Serial No. 329,749.
Be it known that we, JOHN J. OONOLLY and Jol-IN HERRON, citizens of the United States, residing in the city and county of Marquette, State of Michigan, have invented certain new and useful Improvements in Machines for Setting Locomotive-Valves, of which the following is a specification.
Our invention relates ,to valve-setting machines, and has for its object to provide an improved mechanism of this type which maf." be easily and quickly operated with less expenditure of time and labor than is now required.
To this end our invention consists in the combinations and details hereinafter described and claimed.
In the accompanying drawings, Figure 1 is a plan view of our improved valve-setting machine. Fig. 2 is a side elevation of the machine in operative position. Fig. 3 is a longitudinal section through one of the rollerboxes. Figs. 4 and 5 are sectional detail views.
In the operation of setting locomotivewheels of the` locomotive upon what are known as Farrington rollers, the Farrington rollers consisting of pairs of rollers mounted upon shafts and bolted together, so as to be placed under the driving-Wheels of a locomotive on opposite sides thereof, so that the wheels may be raised from the rail by the pressure of the rollers. These rollers are operated by hand so as to turn the rollers, and consequently the driving-Wheels of the locomotive, enabling the operator` to set the valves so as to time the operation thereof properly.
As ordinarily employed, the Farrington rollers require from two to four men to operate them in addition to the setter. It is desirable to provide some means whereby the Farrington rollers may be operated with less labor, thus dispensing with the services of so many employees. To this end we provide the mechanism shown in the accompanying drawings, in which the letters a and b indicate parallel shafts having mounted upon the opposite ends thereof rollers a b, respec` tively. These rollers are mounted in boxes h h', adapted to rest upon the rails, bringing the rollers beneath the driving-wheel of the locomotive on opposite sides thereof, as
clearly shown in Fig. 2. The boxes are `connected together by parallel rods h2, screw threaded at their opposite ends and provided with nuts 71,, securing the rods and boxes together. By the ressure of the rollers a b the driving-wheelDs are raised slightly from the track, so that by rotating the rollers a b the driving-wheels may be correspondingly rotated.
In order to provide an efficient means for operating the rollers, we mount upon the shaft l) a fluid-lnessure cylinder d, this Huid-pressure cylinder being suspended from two boxes (Z4, hung upon the shaft, thus allowing the shaft to revolve and the cylinder to oscillate to conform to different angles when the machine is working. This cylinder is provided with a feed d2 and exhaust d. The piston-rod da of the cylinder is connected at its opposite end to a lever c, having forked end portions c loosely mounted upon the shaft c. Itigidly secured to the shaft a between the forked portions of the lever is a ratchet c2, and between the forked portions of the lever we mount a double awl c2 upon a crosspin c3. The lower' end o the lever is pivotally secured upon a cross-pin d5 between forked end portions d of the piston-rod. It will be readily understood that when one end of the pawl c2 is in engagement with the ratchet and the piston-rodd3 is reci rocated it will cause the rotation of the sha t c, and consequently of the rollers a carried thereby. This will in turn cause the rotation of the driving-wheel of the locomotive and the roller b', thus enabling the valve-setter to adjust the valves, as will be readily understood. The Huid-pressure cylinder is controlled by throttling the exhaust, and in order to provide means, for doing this within easy reach of the operator We connect to the exhaust d of the cylinder a flexible hose or pipe g, a section of this hose leading from the exhaust to each side of the locomotive.. At the ends of the hose-pipes we provide a valve f, which controls the exhaust. The construction of this valve is indicated in Fig. 5. The valvechamber f contains a partition f3, provided with a passage-way controlled by a valve f4, mounted upon a valve-stem f, supported by a spring f, the partition ja forming passagel waysf2 through the-valve-chamber.
In operating our device the valve-setter holds the valve in one hand. When he wishes to revolve the drivers, he presses the valve f4 from its seat, allowing the motive IIO tluid to escape from the exhaust of the cylinder. This in turn allows the piston to move and .revolves the drivers through the medium of the lever, ratchet, and rollers. When he Wishes to stop the machine, he closes the exhaust-valve, and this allows the Huid-pressure to equalize on both sides of the piston and stops the machine instantly. In order to reverse the motion of the machine, the position of the paWl c2 is reversed through the medium of rods c4, connected by a universal joint c5 to the pin c3, one of these rods extending to each side of the machine, so that the machine may be operated from either side of the locomotive.
lt Willbe understood that we may use any suitable form of fluid-pressure cylinder provided With suitable valves. Ve have found the steam end of a l/Vestinghouse pump to be efficient for this purpose. We preferably use compressed air as the motive fluid, though of course it Will be understood that We do not intend to limit ourselves to this speci'lic fluid.
With the aid of this machine We have found that one man can set the valves of a locomotive in less time than could be done formerly With the aid of at least four helpers.
We claim 1. In a machine forsetting valves, the coinbination of a plurality of load-sustaining rollers, a Huid-pressure cylinder connected with the rollers to operate the rollers, and means for controlling the exhaust from the cylinder to control the operation of the machine.
2. In a machinefor setting valves, the combination of a plurality of load-sustaining rollers, fluid-pressure cylinder mechanism for operating the rollers, an exhaust-pipe connected to the cylinder, and means in the pipe to connect the exhaust and thereby the operation of the machine.
3. ln a machine for setting valves, the combination of parallel shafts, load-sustaining rollers mounted thereon, llui(l-pressun.` operating mechanism comprising a cylinder having a piston and piston-rod mounted upon one shaft, and a connection between the end of the piston-rod and the other shaft whereby the rollers are operated by the operation of the Huid-pressure means.
4. 1n a machine for setting valves, the combination of shafts, rollers thereon, Huid-pressure operating means, a lever loosely mounted on one shaft connected to the fluid-pressure operating means, a pawl pivot ally mounted on the lever, and a ratchet rigidly secured to the shaft and engaged by the pawl.
5. ln a machine for setting valves, the eombination of a plurality of load-sust ainin g rollers, means for operating the rollers, 1n x,ans for controlling the operating means, and means for reversing the direction of rotation of the rollers.
6. In a machine for setting valves, the com bination of shafts, load-sustaining rollers mounted thereon, a {luid-pressure operating mechanism, and a ratchetand-pawl m echanism connecting the operating mechanism with. one shaft and reversing mechanism.
7. In a machine for setting valves, the combination of shafts, rollers supported thereon, an operating device, a ratchet secured to one shaft, a lever loosely mounted on the shaft, a double pawl pivoted on the lever, and means for throwing either one of the pawls in en,- ga gement with the ratchet.
