DRAW-BAR STO P.

SPECIFICATION forming part of Letters Patent No. 609,737, dated August 23, 1898.

Application filed July 8, 1897. .Serial No. 643,905. (No model.)

T 00% whom it may concern.-

Be it known that I, CHARLES H. EMERSON, of Marshalltown, in the county of Marshall and State of Iowa, have invented certain new and useful Improvements in Draw-Bar Stops and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. I

This invention relates to draw-bar stops for freight-cars, and which for convenience I call the Emerson common sense draw-bar stop. These stops consist of castings about nine inches long, about siX inches wide, two inches thick at the front end, and one inch thick at the back end, provided with a rib or lug at the back end on one side.

The purpose of the invention is to angm ent the strength and durability of draft attachments. I y

The invention consists in the combination, with the draft-timbers of a railroad-car, of draw-bar stops, each having a single rib at its outer end and having four bolt-holes arranged in pairs, the pairs being in line with each other, and a guide-strap-bolt hole about the middle of the stop and between the pairs of bolt-holes.

In the drawings, Figure 1 is a plan showing the draft-timbers of a railroad-car with my invention applied thereto, the upper guidestraps for holding the follower-plates in position being removed. Fig. 2 is a perspective showing one of the draft-timbers with my improved stops applied thereto and with the guide-straps in position.

l 1 are the draft-timbers, of usual form and character. v

2 2 are my improved stops connected with the draft-timbers by means of bolts 3 3, four of them being used for each casting that is to say, two bolts on either side of the guidestrap bolt and in line with each other, so that the timbers will be mutilated as little as possible, and that in line of the grain in order to avoid weakening the timber by reason of a multiplicity-of holes, each in a different plane from that of the other.

In my improved stop the guide-straps at are connected with the stop by bolts, which pass through the middle of the length of the stop,

thus giving a pair of bolts for fastening the stop to the draft-timber 011 opposite sides of the guide-strap bolt. By forming the guidestrap-bolt hole as far as possible from the face of the stop against which the followerplate abuts the strengthof the face of such stop is greatly increased and the danger of breakage is largely eliminated and to a cor that the guide-straps and bolts are thus relieved from any strain whatever.

The casting 2, which constitutes the principal feature of my invention, is provided with a single rib or projection 5 for interlocking with the draft-timbers, and that at the end farthest from the follower-plates, so that the draft-timbers are out at a distance from the bolt-holes, and thus there is left a maximum of strength in such timbers where the greater strength of the timbers is required. Recesses or channels 6 6 are formed in the manner shown in the drawings for purposes of lightening the castings and to form channels for the heads of the bolts to prevent them from turning as the nuts are tightened up in fastening the stops. to the draft-timbers. The draw-bar 7 and the follower-plates 8 8 are of any usual or approved form or character.

Having thus described the invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A draw-bar stop consisting of a casting provided with guidestrap-bolt holes at about the middle of the length of said stops, and bolt-holes for securing the stop to the draft timbers on opposite sides of the guide-strap hole, substantially as described.

2. A draw-bar stop consisting of a casting provided with a single rib or projection at the back end, guide-strap-bolt holes about the middle of the length of said stops, and boltholes for securing the stop to the draft-timbers on opposite sides of the guide-strap-bolt hole, substantiallyas described.

3. The combination of the draft-timbers of a railroad-car, draw-bar stops each having a single rib at the back end, a guid e-strap-bolt hole through the middle of said stop, a pair of bolt-holes for securing the stop to the tin1- her on either side of the guide-strap bolt,

guide straps, and follower plates, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscrib- 1c ing Witnesses.

CHARLES H. EMERSON.
