JDRAFT RIGGlNG FOR o-AR FR -M Es.zff

SPECIFIGATIQN forming part of Letters Patent No. 592,171, dated October 19, 1897;, ApplicationflledDe0em'be123,1396. -Seria1No.616,' 747. .(Nomodela To all whom it may concern.-

Be it'known' that we, EDWARD M. ROBERTS and EUGENE O. SPALDING, citizens of the United States, residing at Atlanta, Fulton county, Georgia, have invented certain new and useful: Improvements in Draft-Rigging for Tubular or other Metallic Frames for Cars, of p which the following is a specification.

Our invention relates more particularly to improvements in the draft-rigging of cars where the: draft-arms join with the center'- plate-and the center-plate'with the sub-sill, whereby the strain produced 'by" buffing shocks is distributed at those points, and also to the manner of securing the draft-frame at its forward end to the metal end sill.

Our invention also consists in novel fea-' tures of construction that will be hereinafter described, and pointed out in the claims.

In order that our invention may be fully understood, we will proceed to describe the same with reference to the accompanying drawings, in Which Figure 1 is a plan view of the draft-arms attached to center-plate. Fig. 2 is a side elevation of the same. Fig. 3 is an end elevation of the metal end sill of a car and showing the manner of securing the draft-arms at that point. Fig. 4 is a detail sectional view of one of the draft-arms. Fig. 5 is a detail side elevation of the draft-arms, showing a modification which is particularly advantageous on hopper cars when the subsill cannot be applied. Fig. 6 is aplan .view of the form shown in Fig. 5.

In the said drawings, 1 represents the draftarms, 2 the center-plate to which the draftarms are secured by the

bolts

3, and 4 the body-bolster, which consists of a channel of metal with wood fillings. The center-plate is secured to the bolster by means of the bolts 8.

9 represents the heel-plate, bent as shown and having one end 10 bent over the bodybolster, so as to afiord a bearing therefor, and the other end 11 bent under the subsill12, as shown. The object of these plates is to protect the ends of the subsills.- They also remove the entire strain of buffing shocks from the center-plates and bolts and impart it to the subsill, which extends between the two body-bolsters of the car and is connected draft arms at that end of the car, so that the subsill prevents any bending or buckling'ot' the body-bolsters.

13 represents a bolt for securing the heelplate to the subsill 12'. 16 represents the cap of the metal end sill of a car, and 14 the usual arch in which the ends .of the draft-arms fit and are secured.

The arms are secured in the arch by means of the. bolts 15, which pass through'the sillcaplfi and the ppenings 17, preferably elongated, in the arms 1 and held by the nuts 18.

Near the ends of the draft-arms which are held in the arch, lugs or projections 18 are provided on the top and bottom thereof. These projections or lugs are cut out or reat its other end in as'imilar manner with the cessed at 18 to permit the'adjacent edges of the arch to fit against the endof the recess, while the projecting portions 18 of the top lugs or projections fit over the top 'of'the arch, and the portions 18 of the lower lugs or projections fit under the arch; With this arrangement for the ends of the draft-arms the end sill and arch are better able to withstand construction it will be seen that the several parts at this point are so arranged and held that they brace each other and form practically one piece, and no parts project beyond the arch (see Fig. 1) to become broken by the coupler-head coming against them when cars are coupled. This arrangement also permits of a free space for the coupler-head to move in when the cars are coupled, so that the springs of the coupler-head will take up the shock of coupling. 20 represents the coupler, and 21 the follower. This arrangement also does away with all obstructions-such as washers, nuts,and ends of bolts-which would ordinarily come in contact with the coupler when it is placed under severe buffing shocks.

In Figs. 5 and 6 we have shown a modification. In this form we provide'straps 23, lo-

cated on the inside of the body-bolster, and pass bolts 25 over the body-bolster, as shown, and through the straps and draft-arms. These straps are secured at their lower ends by the bolts 24:, which secure the draft-arms to the center-plate. By this arrangement the pulling strain is placed on the body-bolster in addition to the center-plate and the center-plate bolts. In this form the arrangement of heelplate is the same as that in the other form.

Having thus described our invention, what we claim as new therein, and desire to secure by Letters Patent, is

1. The combination of the draftarms, the center-plate carrying the body-bolster, the subsill, and a heel-plate placed between the subsill and body-bolster, and bent to have a bearing on each substantially as shown and described.

2. The combination of the draft-arms, the subsill, the center-plate and body-bolster carried thereby, bolts passing over the bodybolster and passing through the draft-arms and straps located on the inside of the bodybolster, said straps being secured at their lower ends by bolts which pass through the draft-arms and center-plate, and the heelplate, located between the subsill and bodybolster, substantially as shown and described.

3. The combination of the sill-cap at the end of a car, the arch, the draft-arms, each having an end fitting in the arch, alug or projection formed on the top and bottom of each arm near the end thereof, said lugs or projections being recessed or cut out to receive the adjacent edges of the arch, bolts passing through the sill-cap, arch and ends of draftarms, and spools or blocks interposed between the sill-cap and arch; substantially as described.

4. The combination of a sill-cap at the end of a car, the arch, the draft-arms each having an end in the arch, a lug or projection formed on the top or bottom of each arm near the end thereof, said lugs or projections being recessed or cut out to receive the adjacent edges of the arch, bolts passing through the sill-cap, arch and ends of draft-arms, and spools or blocks interposed between the sillcap and arch and'adapt-ed to have the ends of the lugs or projections at thetop of the draft-arms bear against them; substantially as described.
