Patented Dec. 3, 1895.
UNITED STATES PATENT OFFICE.
IVILLIAM CASE, OF CHICAGO, ILLINOIS, ASSIGNOR TOY-THE NATIONAL MALLEABLE CASTINGS COMPANY, OF CLEVELAND, OI-IIO.
SPRING-PLANK FOR CAR-TRUCKS.
SPECIFICATION forming part of Letters Patent No. 550,907, dated December 3, 1895.
Application filed March 2 8, l 8 9 5.
T0 all whom it may concern:
Be it known that I, WILLIAM CASE, of Ghicago, Illinois, have invented certain new and useful Improvements in Spring-Planks for Car-Trucks, of which the following is a specifcation.
The object of my invention is to provide a simple, economical, and efficient springplank; and the invention consists in the features and combinations hereinafter described and claimed.
In the drawings, Figure 1 is a plan view of my improved spring-plank, looking at it from the betteln; Fig. 2, a plan view of the same, looking at it from the top; Fig. 3, an enlarged transverse section taken on line 3 of Fig. 2, and Fig. 4 a side View of Fig. 3.
In constructing my improved spring-plank I use two spring-plates A, of the desired form and size, formed, preferably, of malleable iron and provided With several ribs a on the bottom of the recess for the purpose of giving the plates the requisite strength to withstand ordinary working stress and also to provide pockets for the reception of the connectingrods.
I connect the spring -plates together by means of two iron rods B, having their ends Z) bent at right angles to iit in the pockets above referred to in the lower side of the spring-plates, and I secure these rods B together, preferably in an X shape, by means of a metallic clamp C, formed, preferably, in two portions and bolt or rivet them together at c.
I provide transom-columns D, U -shaped in cross-section, as shown on line 3 of Fig. 2, and reduce the size of the end d so that it will snugly iit the socket cast for it in the spring-plate. These transom-columns have a iianged inner surface d', and an interior chamber which is provided with four ribs d2, that t loosely around the bolt E that joins the transom-columns, arch-bars, and springplat-e together, as hereinafter described. The upper and lower ends of the transom-columns are bored out to snugly iit the bolt and prevent any lateral motion thereon.
To securely bind all the parts of the springplank together and with the arch-bars, I provide the upper end of the transom-column, as at d3, with a groove or slot adapted to receive the arch-bar G, and the lower surface Serial No. 543,440. (No model.)
of the spring-plates with ribs, as at a', lto form a slot or groove a2, that will receive the arch-bar I-I. I then join these arch-bars, transom-columns, and spring-plates together by means of the bolts E, which are provided at their upper ends with a head c and at their lower ends with lock-nuts e.
While I have described these connectingrods as round bars, I do not desire to be limited to such bars, as I contemplate using different shapes of rods in cross-section-as, for instance, T-rods or channel-shaped rods.
I claiml. A spring plank for car trucks composed of two metallic plates forming spring seats provided with pockets on the under side to receive connecting rods, a Vrod or rods connecting the spring plates together, and means for rigidly securing the lplates and rod or rods together, substantially as described.
2. A spring plank for car trucks composed of two metal plates forming spring seats provided with pockets on the under side to receive connecting rods, two connecting rods provided with angular ends fitted in the pockets of the plates, and means for rigidly securing the rods and plates together, substantially as described.
3. A spring plate for car trucks composed of two metal plates forming spring seats provided with ribs on one of its surfaces forming pockets for the reception of connecting rods and slots for an arch bar, transom columns removably secured to the spring plates, connecting rods fitted in the pockets of the plates, and bolts to secure the arch bars, transom column, spring plates and connecting rods together, substantially as described.
4.. A spring plate for car trucks composed of two metal plates forming spring seats provided with ribs on its under surface forming pockets for the reception of connecting rods and slots for an arch bar, transom columns removably secured to the spring plates, substantially X-shaped connecting rods fitted in the pockets of the plates, and bolts to secure the arch bars, transom columns, spring plates and connecting rods together, substantially as described.
