Speccaton of Letters Patent.
Patented Apr. 20, 1915i.
Application liled February 14, 1912. Serial No. 677,450.
To all whom 'it may concern Be it known that I, CHARLES J. NASH, a citizen of the United States, and resident of Chicago, county of Cook, and State of. Illinois, have invented certain new and useful Improvements in Draft-Arms for Railway-Cars, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.
The invention relates to the draft arms for railway cars with which the draft gear and coupler bar coperate; and it consists of a pair of draft arms adapted for attachment to the sills of a car and so shaped as to form a suitable housing for the gear, suitable draft lugs for receiving the pulling and bufling stresses transmitted through the gear, and for providing proper flanges and shoulders for engaging the sills of the car.
An exemplification of the invention is fully hereinafter described and is illustrated in the accompanying drawings, in which- Figure 1 is a detail plan view of the draft mechanism of a car, partly in section and some portions being broken away; Fig. 2 is a transverse section on the line 2-*2 of Fig. 1; Fig. 3 is a detail longitudinal section showing some parts of the car and showing the outer face of one of the draft arms in elevation; and Fig. 4 is a perspective of one of the draft arms showing its inner face, some portions being broken away.
The draft arms are designated, generally, by the numerals 10, 11, and the center sills of a railway car are indicated at 12, 13.
The two draft arms are alike in form eX- cept that their faces are oppositely directed. rIhat is to say, they are made as rights and lefts. But one need therefore be described in detail. Each of the arms is provided with a horizontal flange 14 adapted to bear against the lower face of one of the sills. as 12, 13, and to be bolted thereto. It is also provided with an upstanding flange 15 adapted to bear against the inner face of the sill. The body portion 16 of the draft arm depends from the flange 14 and is formed with a rearward forwardly directed shoulder 17 and a forward rearwardly directed shoulder 18 against which, respectively, these rearward and forward followers 19, 20 of a draft gear take their bearing.
The rearward shoulder 17 is reinforced by means of ribs 21, 22 at its top and bottom instanding from the body portion 16 of the draft arm and it is further reinforced by a hollow rib or inward fold 23 of the body portion 16 shown as being on the median line thereof. Y
The forward shoulder 18 is reinforced by a plurality of ribs 24, 25, 26 and 27. The forward end of the arm projects to the front face of the dead plate 28 of the car which is located immediately forward of the end sill 29, this end of the arm being folded inwardly as shown at 30 to form one side of the throat for the coupler bar 31. The draft shoulders 17, 18, are provided with upward extensions 32, 33, reaching to the upper edge of the flange 15 and united by an instanding flange 34. The draft arm is provided with a tail-piece or plate 25 to which may be secured, as by means of rivets, a connecting plate 36 which extends to the opposite end of the car and is similarly attached to one of the draft arms there located.
The upstanding end 33 of the draft lugv 18 forms a shoulder which takes a bearing against the end sill 29. A tie plate 37 is riveted upon the flanges 34 of the two draft arms at one end of the car, rigidly-uniting and substantially strengthening them. By this arrangement the several draft arms of the car become a unit and are firmly braced to the center sills and between the end sills.
There is shown in connection with the draft arms as represented, a friction draft gear of the Cardwell type which comprises a transverse bolt 38 extending through the draft arms and carrying as a part of the shockabsorbing mechanism a pair of springs 39, 40. rllhe body portion 16 of each of the draft arms is shown as having a commodious oblong aperture for the accommodation of these springs, an outstanding shelf or flange 41 being located immediately below this aperture and forming a support for the springs. A stirrup 42 unites the members of each pair of draft 100 arms at their bottoms and upon it rests and diate of the shoulders, and an outwardly exslides the yoke 43 which enoircles the gear tending shelf at the loWer edge of the ap- 10 proper. erture.
