DRAWBAR FOR STREET-CARS.
SPECIFICATION forming part of Letters Patent No. 498,334, dated May 30, 1893.
applicati@ ined sammy 21, 1893. sain No. 463,245. (No model.)
To all whom it may concern.-
Be it known that I, JAMES A. TRIMBLE, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, haveinvented certain new and useful Improvements in Drawbars and` Springs, of which the following is a specification.
The invention relates to improvements in cars, and pertains particularly to an improved buer and means for coupling 'the cars together or securing the Whittle-tree of the team thereto.
The object of my invention is to improve the construction of the car, to dispense with the customary draft bar connected with the same, and to provide durable means which will serve as a buer `and as a yielding coupling either to receive the link for connecting ing a part of the harness of car horses.
In accordance with my invention the line of draft on moving the car is elevated to about the upper level of the car floor and the force is exerted against a yielding cross-head, thus relieving the strain on both the horses and the car and facilitating the starting of the latter.
The invention will be more fully understood from the detailed description hereinafter presented, reference being had to the accompanying drawings, in which- Figure l is a side elevation of the buffer and coupling constructed in accordance with the invention and applied to the platform of a car, the latter being in section. Fig. '2 is a top view of same, the vertical front guard of the platform being in section. Fig. 3 is a vertical section of same on the dotted line 3 3 of Fig. 2. Fig. et isadetached longitudinal section of same on the dotted line 4-4 of Fig. 2.
In the drawings A designates the platform of a car; B the vertical guard for said platform; C the buffer; D the yielding cross-head and E an ordinary coupling link.
The buffer C is a casting composed of the plate F having the ange G and supporting at its center the hollowframe H, within which are secured the longitudinal pins or guide rods I, I. Upon the guide rods I, I, are the coiled springs J and cross-head D, the latter being a casting having the central longitudinal opening K for thelink E, the vertical aperture L for the removable pin M, and the circular end recesses N, N, centrally through which the guide rods I, I, pass and which receive and form a bearing for the inner ends of the springs J. The outer ends of the springs J are retained within the circular flanges O, O, formed on the inner face of the front of the frame H at opposite sides of the opening O for the link E.
The buffer C is secured to the end of the platform of thecar by means of bolts or tie rods P, P, extending entirely through 'the beam Q, and also by means of bolts R, rivets Sand angle-plate T, the latter being upon the platform A, as shown in Figs. l and 2. The bolts R pass downward through the plate T, beam Q and flange G, and the rivets S through the plate F, guard B and plate T. The buffer is thus very securely supported, and being a substantial casting it is durable and entirely capable of withstanding any usual strain to which it may be subjected. The rods I, I, are rigid and pass through apertures at the inner ends of the recesses N so as to form guides for the lcross-head D. The springs J encompass the rods I and to an appropriate degree snugly t the recesses N and circular flanges O.
When it is desiredl to couple the cars together a linkEmay extend from the opening K of the crosshead D of one car through the buerC to the like opening of the adjoining car, the ends of the link being held by the pins M, and when it is simply desired to attach the draft horseor team to the car the Whittie-tree will be connected by means of a link with the cross-head D.
Upon the application of power either through the coupled cars or by the horses to a single car the strain is exerted on the crosshead D and through said head on the springs .,I, which will yield sufficiently to relieve the car from shock .and strainv and facilitate the starting of the car.l While the carsV are in use the springs .I will in great measure prevent any material irregularity or sudden ness of motion in the car and thus promote the ease and comfort of passengers.
The buer and coupling above described arev particularly advantageous for the attachment of a horse or team to the car, since the draft line instead of extending to a point be- ICO 10W the platform is about on aplane with the upper level of the platform, and hence the horses may pull with greater ease and advantage and the whiffle-tree may be readily attached to and detached from the coupling. The fact that the horses instead of pulling against a solid portion of the car exert their force against the springs J is also an advan tage both to the horses and the car.
Without limiting myself to any special style or character of oar, what I claim as my invention, and desire `to secure by Letters Patent, is
1. The car and the buer secured thereto and having the guide rods I I combined with the cross head D moving on said rods and having at opposite ends thereof the receiving recesses N, N and springs J, J encompassing said rods and entering said recesses; substantially as and for the purposes set forth.
2. The car, and the buffer secured thereto and having the guide rods I and ilanges O, combined with the cross-head D on said rods and having the recesses N, and the springs J held in said recesses and flanges; substantially as and for the purposes set forth.
8. The car, and the buffer secured thereto and composed of the plate F, flange G and frame H, combined with the guide rods I, the springs J on said rods, and the cross-head D on said rods, the saidcross-head having the recesses N, opening K and pin M; substantially as and for the purposes set forth.
4. The car, and the butter secured thereto and composed of the plate F, flange G and frame IfLcombined with the angle-plate T, the guide rods I secured in said frame, the springs J on said rods, and the cross-head D on said rods, the said cross-head having the recesses N and opening Kgl substantiallyas and for the purposes set forth.
Signed at New York, in the county of New York and State of New York, this 18th day of February, A. D. 1893.
