SPECIPICALION Iorming part of Letters Patent No. 372,548, dated November 1, L887.

Application filed May 17, 1887. Serial No. 238,558. (No model.)

T 0 all whom it may concern.-

Be it known that l, PETER MAT'rHnws, a citizen of the United States, residing at Escanaba, in the county of Delta and State of Michigan, have invented a new and Improved Car-Frame, of which the following is a specification.

My invention relates to improvements in locomotivetender frames.

The object of my invention is to provide a strong and inexpensive frame which will effectively resist longitudinal transverse strains of both tension and concussion, and in which the timbers may be strongly jointed or united inexpensively without having to mortise or cut away the main longitudinal timbers of the frame.

The improvement consists in certain coustructions-and combinations of parts, hereinafter particularly described and claimed.

In the accompanying drawings, Figure l is a plan of my improved cat-frame, and Fig. 2 a transverse sectional elevation in line to a: of Fig. 1.

The outsidelongitudinal sills, A, are united to form a rectangular outside frame, A, by end sill, A in any well-l nown or preferred manner. A draw-head, B, at one end and a similar head, B, at the other end of said frame are secured thereto and connected with each other by draw-rods O G", arranged parallel with each other, and extending the entire length of the frame upon opposite sides ofits central longitudinal line, and are drawn and held taut in place by bolt-heads a" and nuts 0, to thoroughly brace the frame and receive the pulling-strain of the engine and train.

Longitudinal timbers D D D D D are mortised at their ends to the end sills, A of the frame, and are all located parallel with each other and in the same plane, slightly below the plane of the outside and end sills.

The longitudinal sills A are united to the outer timbers, D D of the frame by blocks E, bolted to said sills and timbers to securely connect them at suitable equal distances along the length of the l'rame,and the said longitudinal timbers are bound together transversely by truss-transoms F, located each a suitable distance from the ends of the frame, and also by central transverse braces, G, located intermediately of the transom-bracesiu the central part of the frame.

The trusstransoms consist of transverse base-platesf, placed beneath the longitudinal timbers D D D D" D and diagonal tie-plates f, which pass over the central timber, D

and through the intermediate timbers, D D, to the lower inner sides of the outer timbers, D D, and are secured by bolts f at their ends to the base-plate f of the transom. Boltsf also pass through the intermediate and central timbers and through the tie-plates f,and bolts f" pass through the outer longitudinal timbers and through the baseplate f and securely unite the truss-transoms to the longitudinal timbers of the frame.

The various parts of the frame are thus securely united without materially weakening the timbers and sills by mortise-joints, and a substantial structure is thus obtained at a minimum cost of construction, which will be braced laterally by transverse braces and trussed transoms, and will be especially fortified against concussion and longitudinal strains.

Pivot-blocks H and hangers I are securely bolted to the trnss-transoms to connect with the truck-bolsters in any well-known or preferred manner, to support the frame upon the trucks in a vertical plane with the truss transoms.

I claim as my invention and desire to secure by Letters Patent 1. In a locomotive-tender frame, the combination, with the longitudinal timbers, of the outside frame having end sills supported upon the ends of said longitudinal timbers, drawheads secured to the end sills, and parallel draw-bars extending the entire length of the frame and coupled to the draw-heads, substantially as described.

2. In a locomotive-tender frame, the combi nation, with the outside frame, of a series of longitudinal timbers extending the entire length of the frame and below the plane thereof, transverse braces connecting the longitudinal timbers, and a series of block-castings, E, secured to and interposed between the outside longitudinal timbers and the side sills ofthe outside frame, substantially as described.

3. In a locomotivetender frame, the combination, with the outside frame, of the longitudinal timbers secured to transverse braces G tending from end to end thereof, united by IO beneath the same, and trussed transoms F, transverse braces and truss-transoms and sup having base-plate f, located beneath said-timported partly below the plane of the outside bers, and a tie-plate, f, passing over the cenframe, substantially as described. 7
