LOUIS, MISSOURI, A CORPQRATION OF MISSOURI.

DRAFT MEcHANIsM.

1'0 all 'whomz't may concern.'

Be it known that LTI-IARRY E. DoERR, a citizen of the United States, residing at St. Louis, in the county of St. Louis and State 5 of Missouri, have invented certain new and useful Improvements in Draft Mechanism, of which the following is a specification.

This invention relates to draft mechanism.

In most draft arm constructions used nowadays there is an offset at the body bolster, the draft arms running straight from the front end of the car back to the body bolster and then inclining upwardly and over the bolster, the arms usually being secured to either the sides or bottoms of thc sills. This type of draft arm has the disadvantage of transferring the impact of the blow on the coupler through the draft arm to the top member or portion of the body bolster. This should be obviated.

Accordingly, one object of my invention is to overcome this and other disadvantages and to provide a simple, durable and compact draft mechanism wherein the draft arms and the body bolster are connected in an improved manner to meet all the requirements under service conditions.

This and other objects are accomplished by means of the mechanism shown on the accompanying sheets of drawings, in which- Figure 1 is a plan view of draft mechanism embodying my invention;

Fig. 2 is a fragmentary longitudinal sectional view of the same arrangement, the draft arms being shown in full lines and the body bolster and connecting parts shown in dot and dash lines;

Fig. 8 is a fragmentary e'nd view of the draft arms showing their association with the body bolster and means for connecting said parts together; and

Fig. 4 is a sectional view taken in the plane of line 4-4 of Fig. 1.

VThe various novel features of my invention will be apparent from the following de-V Specifcaticn of Letters Patent. Ptgnd. S91}1; 21, 15;.;2()

inclining upwardly land passing over the same, are reduced vertically at the body bolster in order that the draft arms may passin arstraight line through and extend beyond said bolster. ably pass through spaced openings 14 in the body bolster 13 and are secured to adjacent vertical flanges 15 of the body bolster by rivets 15 which may pass through holes 16 in said flanges. Not only are the draft arms 10 secured to the body bolster at the flanges 15, but they are also rigidly connected tothe body bolster by gusset plates 17 at the rear of the body bolster and 'gusset plates 18 in front of the body bolster. These gusset platesk connect the upper and

lower flanges

25 and 26 of the draft arm to the upper and lower flanges 19 and 2O of the body bolster, said parts being secured together by suitable rivets 24. These draft arms are secured beneath the center sills 21 of the car which overlie the body bolster. A reinforcing plate 22 also is interposed between the upper surface of the reduced rear portion of the draft arm and the overlying portion of the car center sills, said plate 22 being These draft arms v10 prefer-V secured to the draft arms and body bolster by suitable rivets 23.

By means of this construction the impact of the blow on the coupler is not transferred through the draft arms to the top of the body bolster, but properly distributed throughout the depth of the bolster. Furthermore, the construction is simple, compact and rigid, and adapted to meet all the requirements under service conditions.

It is my intention to cover all modifications of the invention falling within the spirit and scope of the following claims.

' I claim:

1.y In draft mechanism, the combination of a bolster having openings therein, integrally formed draft arms extending through the said openings' and being secured to said bolster, and gusset members connecting said draft arms and bolster.

2. In draft mechanism, the combination of a bolster having openings therein, integrally formed draft arms extending through said openings and being secured to said bolster, said bolster and draft arms having flanges, and gusset plates secured to the flanges of said arms and bolster.

3. In draft mechanism, the combination of a body bolster having openings therein and adjacent flanges, single piece draft arms extending through said openings and being secured to said flanges, and gusset plates connecting said draft arms with said bolster.

4. In draft mechanism, the combination' of a body bolster having openings therein and associated vertical flanges, said bolster also having upper and lower laterally extending flanges, draft arms extending through said openings and being secured to said vertical flanges, .said draft arms having upper and lower laterally extending flanges, and gusset plates connecting the upper and loWer flanges respectively of said draft arms and bolster.

5. In draft mechanism, the combination of an integrally formed bolster having an opening therein, an integrally formed draft arm having a reduced portion extending bolster at the reduced portion of the draft arm.
