STOP-CASTING'.

Specification of Letters Patent.

Patented Aug. 26, 1919.

Application led January 20, 1919. Serial No. 271,950.

T o all whom t may concern:

Be it known that I, lVILLIAM A. Galena, a citizen. of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Stop-Castings, 0f which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to improvements in stop castings.

The object of the invention is to provide a strong and durable stop casting or cheek plate for railway draft riggings and more particularly one which may be easily manufactured without the use of the usual cores, and wherein the riveting area is uniformly disposed.

In the drawing forming a part of this specification, Figure 1 is a side elevation of a stop casting of the tandem form embodying my improvements. Fig. 2 is a horizontal, sectional view, taken substantially on the line 2--2 of Fig. 1. And Figs. 3, 4, 5 and 6 are vertical, sectional views taken on the lines 3--3, Ll-Jl, 5 5 and 6-6, respectively, of Fig. 1 looking in the direction of the respective arrows.

In said drawing, the improved cheek plate or stop casting is shown as comprising a main back wall or plate 10 which is adapted to fit against the draft sill to which the cheek plate is riveted. The plate 10 is provided at each end thereof with an inwardly extended vertical convolution 11-11, and at the center with a wider vertical convolution 12, said convolutions 11 and 12Jforming the front and rear main stop shoulders 13 and 14 and the front and rear intermediate main stop shoulders 15 and 16. At each end, beyond the main stops 11-11, the plate proper is provided with a series of rivet holes 17-17, as clearly shown in Fig. 1 and for strength, an inwardly extended flange 18 is formed, the upper and lower horizontal portions thereof being tapered inwardly to merge with the outer faces of the end stops as indicated at 19-19.

Intermediate each end stop and the central post 12, the casting is provided with two inwardly extended ribs 20 and 21. The ribs 20 and 21 extend from the upper corner of one post to the lower corner of the next post and said ribs cross on the median line of the casting so as to form an X-braeing between each pair of main stop shoulders. This construction leaves four riveting areas 22, 23, 2li and 25 between each pair of stop shoulders, said riveting areas being symmetrically arranged and forming in effeet al Maltese cross, it being understood that the casting has inwardly extending upper and lower flanges 2G and 27 intermediate each pair of stop shoulders. The respective riveting areas are provided with a substantially centrally located rivet hole, as indicated at 28.

At each intersection of the Xribs the casting is extended inwardly beyond the inner faces of the ribs but to a distance less than the depths of the main stops so as to form hollow limiting Stops, as indicated at 29-29. Each of these limiting stops 29 has two vertical faces forming limiting stop shoulders 30-30 corresponding to the nearest main stop shoulder. The upper and lower faces of each limiting stop 29 conform to the slope of the ribs 2() and 21, as will be apparent from an inspection of Fig. 1.

The casting is made of substantially uniform thickness throughout so as to eliminate as far as possible all casting and annealing strains, all T-seetions being eliminated. Furthermore, it is evident from an inspection of the casting as shown in the drawing, that the same can be molded without the use of the usual cores, thus presenting a casting that can be cheaply manufactured in quantity. It will also be noted that the riveting areas are uniformly distributed so as to provide series of rivet holes arranged in three horizontal lines, one centrally of the casting and one above and one below.

Although I have herein shown and described what I now consider the improved manner of carrying out my invention, the same is merely illustrative and I contemplate all changes and modifications that come within the scope of the claims appended hereto.

I claim:

1. As an article of manufacture, a stop casting for railway draft riggings comprising, a plate having the main portion thereof in the outer plane adapted to fit against a draft sill, said plate having formedthcrein a plurality of vertically arranged, lougitudinally spaced, convolutions extending in wardly and forming the main stop shoulders,

Copies of this patent may be obtained for Vthereof' in the outer plane adapted tozit against a draft sill for riveting thereto, Said plate having formedtherein three vertically arranged, longitudinally spaced convolu-V tions extending inwardly and'forming the Washington, DQ C.

main, end'and intermediate stop Shoulders7 said plate having also a pair of ribs hetween each Set of mainy end and-intermediate stop shoulders, each set of ribs being of X forn'iation and extending inwardly from the main portion of the plate7 the point of intersection of each Set of ribs being located substantially midway betweeneach `eet of main Y end and intermediate stop shoulders, the

casting being provided with a hollow boss at the intersection of each X-formation of ribs to provide` limiting stops.' In witness that I Claim the. foregoing I have hereunto -subscribed my name this 2nd 4' day of Jan.v 1919. p
