TRIPLE-VALVE CLAMP.
Specification of Letters Patent.
Patented Sept. 26, 1905.
Application and March 15,1905 Serial No. 250,157.
T at whom it may concern.-
Be it known that I, OVID L. WRIGHT, a citizen of the United States,residi'ng at Richmond, in the county of Contra Costa and State of California, have invented new anduseful Improvements in Triple-Valve Clamps, of which the following is a specification.
\ My invention relates to a device which is especially designed for holding the triple valve of an air-brake mechanism in place upon the inspecting and repair table.
air-brake mechanism it is found expedient to remove the casing containing these valves from its operative position upon the car and or connections 6 from the plunger or piston to place it upon a table or support where it can be fixed so that it. can be taken apart, inspected, and reassembled. For the purpose of holding such valves various clamps with screws operated by hand have been used. My invention is designed to provide a rapid, convenient, and secure holder for these peculiarlyshaped valve-casings while the inspection or.
repalrs are going on.
As shown in the drawings, A represents a work bench or table of any suitable description having upon one side anupwardly-projecting standard 2. To this standard is fulcrumed a lever 3, having a forked or'other suitably-formed end, as at 4, adapted to fit a part of the valveecasing and to hold it against the standard 2. This standard has certain openings made through it to coincide with the working openings of the valve-casing, and a washer or gasket, as at 5, is fitted at this point,
. so that when the face of the valve-casing is placed against this washer it may, under compression, form a tight joint. In order to operate this lever, I have shown a plunger-rod of a cylinder 7, which is suitably located, preferably beneath the bench, so that the plungerrod may extend up through an opening in the bench and connect with the longer arm of the lever 3, as shown. The cylinder 7 is connected by a pipe with a reservoir containing air under pressure, as at 8, and a suitable controlling-valve 7is so disposed that by moving of the valve air is admitted into the cylinder 7, and the pressure .thus acting upon the piston or plunger in the cylinder will force the plunger-rod 6- upward, so that, acting upon the lever 3, it will cause the end 4 to firmly clamp the valve-casing against the gasket 5. thus making a tight joint and holding the device in position while the necessary inspection and testing goes on.
In order totest the working of the valve, the
pipe, as at 9, connects with an auxiliary cylinder, and another pipe, as at 10, connects with the brake-cylinder, these parts being located with regard to the testing-bench and to the valve when in place so that all the operations ofthese parts may be carried out in the same manner that they would be when in working position upon the train, and the inspector can readily determine the eflicacy of the valve.
By means of this simple air-pressure clamp I am enabled to rapidly place the valve-casing in position and hold it firmly with relation to the connections through which the testing is i to be done without any mechanically-operated clamps. By this means a great deal of time is saved in bolting or otherwise fastening the parts in place. I
The plug-cock serves to retain the air in the reservoir when the valve is cut ofl'..
Having'thus described my invention, What I claim, and desire to secure by Letters Patent, 1s
1. A testing-machine comprising a work bench or table having upon one side an upwardly-projecting standard, said standard having a gasket against which a removed valve-casing is fitted and having openings for pipe connections, a bent lever fulcrumed to the table-standard, having one end forked to straddle the valve-casing and having the opposite end extended over the table, and an aircylinder and piston foroperating the lever. 2. A ,triple-valve-testing stand having a standard fixed thereon, pipe connections from a brake-cylinder and auxiliary air-pressure reservoir through the face of said standard, said connections coinciding with similar passages, of a triple-valve casing, a gasket fixed In testimony whereof I have hereunto set my hand 1n presence of two subscrlblng witnesses.
