- and to transmit. to the car framing the stresses of draft and bufiing. .Thes e arms are of especial value in connection with cars having wooden underframing, and may be applied to either old or new cars.-

The principal object of the invention is to provide a draft arm formed of wrou ht metal, to which is secured a bufling ug adapted to bear against the body bolster of the car.

The embodiments of the invention are hereinafter described, and illustrated in the accompanying drawings in which Figure 1 is a detail longitudinal section of the car frame showing the draft arm in elevation.

Fig. 2 is a plan view of the arm shown in Fig. 1;

Fig. 3 is a detail section on the line 33 of Fig. 1;

Fig. 4 is a view similar to Fig. 1, showing a modified form of construction.

Fig. 5 is a plan view of the arm shown in Fig. 4:; and

Fig. 6 is a detail section on the line 6-6 of Fig. 4:.

One of the center sills of the car is represented at 10 and as being of wood, and the end sill is shown at 11. The draft arm is of wrought metal pressed into form, and comprises a body portion 12 adapted to bear against the inner face of the sill 10 and extend over and beyond the body bolster 13 of the car. The body portion 12 of the arm is provided along its upper margin with an instanding stiffening flange 14:, and may be of less height forward of the bolster than in the portion extending over and beyond the bolster. Forward of the bolster, however, the body portion extends downwardly, as shown at 15. this downward extension preferably abutting against the bolster 13 and extending forwardly under the end sill 11.

' An angle bar 16 is riveted to the outer face of the arm section 15; in such position that its outstanding leaf bears against the under face of the sill 10. From the rear end of the section 15 the body portion 12 is provided with an outwardly turned flange 17, which engages the lower face of the sill 10. Bolts, as 18, 19,'are passed vertically through the sill 10 and the angle bar 16 and flange 17,*for securing the arm to the sill.

Draft and bufiing lugs 20, 21,preferably of cast metal, are applied to the inner face of the arm section 15 and are securely riveted thereto. The .bufling lug 21 extends backwardly to and abuts against the bolster 13. .Bufling stresses are transmitted through the lug 21 in part to the draft arm section 15 but largely directly to the bolster 13,

The construction shown in Figs. 1, 2 and 3 y is applicable to cars having the present standard sill spacing. In cars in which the sills are spaced a less distance than the present standard, the arm is modified in construction as shown in Figs. 4, 5 and 6, to

provide for the use of draft mechanism of standard width. To this end the depending portion 22 of the arm, forward of the body bolster, is offset outwardly, there being formed between it and the body portion 12 an outstanding shelf 23, which fits against the under face of the sill 10 and through which the attaching bolts 18 pass, thus dispensing with the angle bar 16. When this form of construction is followed the draft and bufiing lugs are located directly below the sill.

In both forms of construction the depending section 15, 22, of the arm is flanged outwardly at its lower margin, as shown at 24, 25, for the purpose of increasing the rigidity of the member. The arm is provided with a shoulder for abutting against the rearward face of the bolster, and preferably this shoulder is provided by securing to the lower face of the outstanding flange 17 a plate 26.

The bolster may be of any desired form of construction, as may also be the draft and buffing lugs, it being important only as toone feature of the invention that the bufiing lug be prolonged and have a bearing against the bolster. The structure may be otherwise modified as to detail without departing from the scope of the invention.

I claim as my invention- 1. A draft arm formed of wrought metal and having a body portion adapted to bear against the inner face of a car center sill and to extend from the end sill of the car over and beyond the car bolster, and being provided with a depending portion extending below the car sill and located forward of the bolster and being ofl'set outwardly to form a horizontal shelf for engaging the lower face of the sill, the upper margln of the body portion being flanged inwardly and the lower margin of the depending ortion being flanged outwardly, and a bu ng lug secured to the inner face of the depending portion of the arm and adapted to bear against the car bolster.

2. A draft arm formed of wrought metal and having a body portion adapted to bear against the inner face of a car center sill and to extend from the end sill of the car over and beyond the car bolster, and being provided with a depending portion extending below the car-sill andlocated forward of the bolster and being offset outwardly to form a horizontal shelf for engaging the ing below the car sill and located forward of the bolster and bein offset outwardly to form a horizontal she f for engaging the lower face of the sill and havlng an instandin flange at its upper margin and an outstan ing flange at its lower margin.
