STEAM-FITTING FOR RAILWAY-CARS.
SPECIFICATION forming part of Letters Patent No. 398,620, dated February 26, 1889.
Application filed December 14:, 1888. Serial No.Z93,616. N0 model) To all whom it 71mg; concern:
Be it known that l, LESLIE .I). JOBES, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented certain new and useful Improvements in SteanrFit ti ngs for Railway- Cars; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to st cam-fittings for railway-cars; and it consists in improvements in the construction of the universal joint in the steam-conduits at the ends of the cars,as will be hereinafter fully d escribed, and poi nted out in the claims.
My invention is illustrated in the accompanying drawings as follows:
Figure 1 is a longitudinal section through the joint. Fig. 2 is a perspective view of the joint and its connections. Fig. is a transverse section through one of the joints on the line at w in 1.
Like letters of reference designate like parts in all the figures.
The construction and operation of the de- Fig. 2 shows the position of all the parts 1 when the pipes are all in place. C marks the pipe which connects with the service-pipes of the car. D marks the pipe which connects with a like pipe on the adjoining car by means of a coupler. The slip-joint and coupler are not shown, as they form no part of my invention. A is an elbow having screwthreaded joint-sockets a a at its ends andpivot'lugs a" a, which set at right angles to each other and in an extension of the axial line of the joint-sockets a a 'l T are tierods, which are journaled on the pivots a a and are adj ustahly secured at their opposite ends to lugs 25 on the elbows b b' 011 the pipes i G and D. The elbow A. has its arms extending at right angles to the tierods, one arm I being horizontal and the other vertical, and j the two elbows b 6* have their arms, which are not connected with. the pipes C and D, arranged so that the one on the pipe 0 lies horizontal and. parallel with the horizontal;
3 inner end.
arm of the elbow A and the one on the pipe D stands vertical and parallel with the vertical arm of the elbow A. In the sockets a a of the elbow A are swiveled goose necks, which may be of one pipe, or made, as shown, of the pipes B B [-3 and elbows l) I). These goose-necks have their ends B fixed in the elbows 12 19 respectively. \Vhen the whole device shown in Fig. 2 is in place on a car, the end D will be the free or movable end, and the end C will be the fixed end. It will be seen that the pipe I) can he moved in any direction desiredhorizontalIv, vertically, or in a circle.
In Figs. 1 and the construction of the stuifing-boxes by which the pivoted ends of the goose-necks are packed is shown, as follows: The pipe B has a flange, If, at its lower or The packing P is put. in as commonly. The gland or follower G has on its outer lower side a spline, g, and the socket a. has on its inner wall a groove to receive the spline g, and the nut H goes over the socket a and grapples with the follower G by an internal flange, 71. This form of stuiiing-box is particularly desirable for the place on account of its compactness and because it will keep dustoff of the working-faces. The object of the spline and groove is to keep the follower from turning with the pipe B and working the nutI-l loose.
I am aware of the constructions shown in the following patents: English Patent No. 5,839 of 1882; United States Patents Nos. 193,679, of July 81, 1877; 210,159,0f Dccember3, 1878; 276,186, of April 2t, 1883; 289,120, of November 27, 1883; 331,806, of December 8, 1885, and 393,908, of December l, 1888.
While my present construction embraces many primary features which are found in some or all of the constructions cited, such features do not constitute my present invention.
What I claim as new is 1. The elbows A, having sockets with stuff ing=boxes at the ends of its arms and pivot lugs 0/ at its angle in axial line with said sockets, in combination with two goose-necks swiveled and packed in said sockets and the tie-rods T, journaled on said pivot-lugs a.
and adjnstably connected with lugs on the said pivot-lugs and ad j ustably c0nnected \\"ith swinging ends of said goose-necks. the swinging end of the goose-neck, which is 2.
