Description
STATES naca ' PATENT GFFIcn GEORGE WESTINGHOUSE, JR., OF PITTSBUR l, FENNSYLVANIA.
Specifica-tion forming part of Letters Patent No. 116,655, dated July 4, 1871.
To all 'whom t may concern:
` Be it known that I, GEORGE Wns'riNG-Housn, J r., of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in. Valve Device for Steam- Power Air-Brake Couplings 5 and I do hereby declare the following to be a full, clear, and exact description thereof, reference being' had to the accompanying drawing making a part of this spec` iiication, in which- I Figure 1 is a longitudinal section of the male and female parts of a pipe-coupling fitted with my improvement, the valve being in the male part; and Fig. 2 is a like view of the same, except that the valve is in the female part and the stem by which it is unseated is in. the male part.
Like letters of reference indicate like parts of each.
My presentinvention relates to the construction of valve devices for the coupling-pipes of steam-power air-brakes of railway cars, of the same classas is described in Letters Patent a-lready granted to me, April 13, 1869, and November 29, .1870, and consists in a conibination of devices somewhat modified from any of the forms heretofore patented tome, and in which modifi ed form a valve arranged in one part of the coupling is unseated by a fixed inflexible stem in the other part, the valve in all other respects operating' in the manner heretofore described.
To enable others skilled in the art to make and use my invention, l will proceed to describe its construction and manner of use.
The male and female parts A and B of the coupling are made of any suitable form. They are attached to the iiexible pipes by their corrugated ends A' B', and are iitted with packing a, fastening spring-hooks b, and adjustable rings c in the usual way. In Fig. l the male part A has a valve-chamber,A d', in which is arranged the valve c, having' guiding-win gs c', or other equivalent devices, by which it is guided in its motion to and from its seat c. "When the two parts `of the coupling are disconnected the pressure ofthe air back of the valve c will always press it to its seat, so that in such ease it will be practically a pipe having a closed end, and the air will be prevented from escalfiing. ln the female part, a-nd across the opening at an`y suitable point, is iiXed a bar, f, from which a rigid inflexible stem, f projects ioiuvard far enough, and in such posi tion as that, when the couplings are united, it will engage some part, say the stem j' of the valve c, and force it' back from its seat far eiiough to lleave an open passage-way around for the fiow of air. In Fig. 2 the same combination is shown, except that the valve c is arranged in a suitable wtlve-chamber of the female part of the coul'iling, and the cross-bar j' and stem j" in the male part ofthe coupling.
ln furnishing cars with such couplings the female parts may be placed on the corresponding ends of all the cars of any one road, andthe male parts on the opposite ends; or, what is a better arrangement, two coupling pipes may be employed at each end of each car, such pipes of each pair meeting at er short of the brake-cylinder. Then, on all the cars of the road, and on both ends of each car, the right-hand coupling-pipe should be fitted with a male or female coupling, and the left-hand coupling-pipe with the corresponding female or male coupling, the arrange ment of the valve in the male or female parts being uniform in all the couplings, and likewise that of the bar and stem. This latter arrangement, however, will constitute a part of the subj ect-matter of a separate application. Then, when the cars are coupled together, an open iminterrupted passa ge-wa-y will be openthrough the entire train for the iiow of the air, which for this purpose is to be compressed by steam-power into a suitable reservoir, and the pipes of the rear end of the last car may be coupled together. This construction an d arrangement, however, will form the subj ect-1 natter ofa separate application The stems fl prefer to make of such length that if two couplings, both lifted with cross-bars j' and stemsj", happen to come together, they will not prevent the uniting of the couplings. combination set forth any other suitable form of valve may take the place of the valve c, the only essential points being that it shall be free to close by pressure from behind, and shall be unseated, when the couplings are united, by means of a rigid stem, j', engaging it, or some part of it, or some device connected therewith.
l/Vhat l claim as my invention, and desire to secure by Letters Patent, is-
ln the' Aiigid inexible ste1n, f, arranged in one part VVESTiNGHOUsE, Jr., have hereunto set my of a pipe-coupling, in Combination with zt valve in hand. the other part, the tWo being` so arranged that GEO. WESTINGHOUSE, JR. when the couplings are united the Valve shall be nnseftted by being` brought in Contact with the Witnesses: stein7 substantially as described. A. S. NICHOLSON,-
In testimony whereof I7 the said GEORGE R. C. VRENSHALL.
