CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 624,556, dated. May 9, 1899.

Application filed March 11 1899- Serial No. 707,265. (No model.)

To (0Z5 whom it may concern:

Be it known that 1, JOHN W. SMITH, a citizen of the United States, residing at Columbia, in the county of Columbia and State of Florida, have invented a new and useful Car- Truck, of which the following is a specification.

This invention relates to car-trucks; and the object of theinvention is to providealight and strong device of this character and which can be manufactured at a low cost and from standard and not special or pressed metal work.

With these ends in View the invention consists in the novel combination of elements and in the construction and arrangement of parts, which will be hereinafter fully described and claimed.

To enable others to understand the invention, I have illustrated the preferred embodiment thereof in the accompanying drawings, forming a part of this specification, and in which Figure l is a plan View of a portion of a cartruck constructed in accordance with the invention. Fig. 2 is a side elevation of the same. Fig. 3 is a cross-sectional elevation,the section being taken on the line 3 3 of Fig. 1 and looking in thedirection of the arrow. Fig. 4 is a sectional elevation, the section being taken on the line 4 4 of Fig. 1 and looking in the direction of the arrow.

Like characters denote like and corresponding parts in each of the several figures of the drawings.

In the drawings I have deemed it necessary to simply show one-half of the truck constituting the invention, and said truck includes in its construction a side frame A, having at its opposite ends pedestal-spaces 2, of box-like formation, in which the usual axle-boxes are disposed, and the pedestal-frames,hereinafter more particularly described, entirely surround said journal-boxes (not shown) and are braced in such a manner as to produce a thoroughly staple structure capable of withstanding the severe strains to which apparatus of the present character are ordinarily subjected.

The side frame A includes inits construction a longitudinal channel beam or iron 3,

constituting the main member thereof and of these braces are riveted at different points,

as at 9, to the under side of the web of said channel or beam at points adjacentto the opposite end of the latter.

The rivets 9, which connect the U-shaped braces and main channel-iron, also extend through the longitudinal flat plate 10, which extends from one'pedestal-frame to the other, as will be obvious, and which tends to further strengthen the structure, and this plate has an inward extension 12, against which and substantially at its middle the outer end of the transorn plate 13 fits, said plate being secured in place by aseries of rivets, as 14, in alinement with each other and passing through the two parts.

The pedestal-frames are further strengthened by a brace 15, of channel-iron, which is located above the lower ends of the interior, braces 6 and 7 and which is bent downwardly at its opposite ends, as at 16 and 17, respectively, and at right angles tothe main body thereof. These downwardly-bent portions fit against theinner legs of the U -shaped braces 6 and 7, the parts being secured together by rivets, as 18, passing through the web of the brace or channel iron 15. A flat plate is shown at 19, this being com plemental to and in parallelism with the upper plate 10, and said plate 19 fits against the upper face of the web of the cross-brace 15, a series of rivets, as 20, passing through the two parts, and the ends of this plate sustain the T-

shaped coupling members

21 and 22, which are secured by rivets, as 23, atdifferent points in the height thereof to the inner legs or branches of the U-shaped braces 6 and 7. A series of rivets, as 24, connect the flanges of these coupling members with the 'right-angularly-

bent ends

25 and 26, respectively, of the channel-beams or

cross-girders

28 and 29, the flanges of the latter fitting against the inner faces of the upper and lower parallel plates 10 and 1!), respectively, and being secured together by rivets, as 30. The plate 13 is secured along its opposite edges to the upper flanges of the channel-

beams

28 and 29 by rivets, as 31, and to the lower flanges of these beams a similar plate 32 is secured by rivets, as 34, which pass through the two parts, and these upper and lower plates 13 and 32 overlap the plates 10 and 19.

It is apparent that instead of employing T- shaped coupling members other-shaped devices could be substituted therefor without departing from the spirit of the invention, and it is likewise obvious that other devices than rivets might be employed to hold the parts in assembled relation.

A cartrucl constructed as aforesaid is strong and light and is capable of withstanding the strains and shocks generally present, and it can be manufactured from standard metal shapes, thereby obviating the necessity of constructing special beams and the like for its formation.

Changes in the form, proportion, size, and the minor details of construction within the scope of the appended claims may be resorted to without departing from the spirit orsacrificing any of the advantages of this invention.

Having thus described the invention, what I claim is- 1. In a car-truck, the combination with a main beam having right-angular downward extensions, of inverted-U-shaped braces the outer legs or branches of which are secured to said downward extensions, a longitudinal brace secured to the inner branches of said U shaped braces, coupling members connected with the inner branches of said U- shaped braces, cross-beams having right-angular extensions at their ends secured to said coupling members, upper and lower plates secured to said cross-beams, and a second pair of plates disposed in the spaces between said first-mentioned plates and the cross-beams and overlapped by said first-mentioned plates, substantially as described.

2. In a car-truck, the combination with a main beam having right-angular downward extensions at its opposite ends, of inverted- U shaped braces the outer legs or branches of which are secured to said downward extensions, a longitudinal brace having right-angular downwardly-extendin g portions secu red to the inner branches of said U -shaped braces, coupling members connected with the inner branches of said U shaped braces,cross-beams having right-an gular extensions at their ends secured to said coupling member, upper and lower plates secured to said cross-beams, and a second pair of plates disposed between said first-mentioned plates and the cross-beam, and overlapped by said first-mentioned plates, substantially as described.

3. In a car-truck, the combination with a main channel-beam having right-angular, downward extensions, of'inverted-U-shaped braces the outer legs or branches of which are secured to said downward extensions and the cross portions of which are secured to the main portion of said beam, a longitudinal channel-brace having downwardly-bent rightangular portions secured to the inner branches of said U -shaped braces, cross channel-beams having angular extensions at their ends, T- shaped coupling members secured respec: tively to the inner ends of said cross-beams and to the inner branches of the U-shaped braces, upper and lower flat plates secured to the flanges of said cross-beams, and a second pair of plates disposed between said first-mew tioned plates and the cross-bars and overlapped by said first-mention ed plates,substantially as described.

In testimony that Iclaim the foregoing as my own I have hereto affixed my signature i the presence of two witnesses.

JOHN WV. SMITH.
