DRAFT-RIGGING.

SPECIFICATION forming part of Letters Patent No. 669,843, dated March 12, 1901.

Application filed May 7,1900.

To aZZ whom it may concern:

Be it known that I, GEORGE S. MARSHALL,

'a citizen of the United States, residing at the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in Draft-Rigging, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is avertical sectional view through a portion of a car-body, showing myimproved draft-rigging in position thereon. Fig. 2 is a plan view, the flooring being removed and the end and draft sills being shown partly in section. Fig. 3 is a vertical cross-sectional view on line 3 3, Fig. 1. Fig. 4. is afront elevational view of the casting employed in connection with the draft-rigging. Fig. 5 is an elevational view of the follower-plate, and Fig. 6 is a side elevational view of the casting shown lll Fig. 4.

This invention relates to a new and useful improvement in draft-rigging, the object being to construct the parts in such manner that a short cross-key may be employed in connection with the continuous draft-rods, said draft-rods being short-coupled, so that the liability of bending the cross-key is reduced to a minimum. The timbers are also left intact to a greater extent than is usual with the ordinary form of continuous draftrigging.

With this object in view the invention consists in the construction, arrangement, and combination of the several parts, all as will hereinafter be described, and afterward pointed out in the claims. i

In the drawings, A indicates the end sill, B the draft-sills, and G the floor, of the car, such parts being of the usual construction.

D indicates the coupler shank, which is provided with a cross-key E at its rear end.

It is usual in that type of draft-rigging known as continuous to have the crosskey to which the draft-rods F are connected pass through the casting or castings in which the rigging is mounted or through the wooden draft-sills of the car. It is of course obvious that to the extent that the material is re- Serial No. 15,785. (No model.)

moved from these castings or draft-sills, (unless the parts are reinforced,) Whether made of wood or metal, such parts are proportionately weakened. It is one of the prime objects of my invention to preserve the integrity of the sills as far as possible, and to effect this the'cross-key E is make comparatively short-that is, its ends project later ally but a short distance beyond the side walls of the coupler-shank and are received in pockets or recesses a, provided therefor in the inner faces of the draft-sills. These pockets accommodate the movement of the cross-key, and in order to effect repairs easily without dismantling the entire rigging I prefer to extend one of the pockets entirely through the draft-sill in which it is formed, in order to insert or remove the cross-key through the opening thus provided. By this construction it is possible to arrange the continuous draft-rods F close to the couplershank and between the draft-sills, as shown in Figs. 2 and 3, instead of on the outside of the draft-sills, as is usually done.

9 indicates the tail-bolt of the coupler, and G the draft-springs surrounding the same and bearing at their forward ends against the coupler-shank, while the rear ends of said springs are seated against the follower-plate H, whose construction is best seen in Fig. 5. This follower-plate is recessed at its side edges, as at h, to receive the continuous draftrods, as will be readily understood.

1 indicates a divided casting secured between the draft-sills and forming an abutment for the follower-plate H. This divided casting, as shown in Figs. 2 and 3, consists of an upper portion J, provided with upwardly-extending marginal flanges j, while lugs or cars j extend laterally from these marginal flanges and are received in seats provided therefor in the draft-sills. These seats are in the form of channels opening at their bottoms, and the casting J is introduced in position from beneath, being secured in place by suitable securing-bolts 7' The bottom wall of this upper casting is formed with a slotj in alinement with the tail-bolt of the coupler, which slot receives a key g, passing through said tail-bolt. By this arrangement the iongitndinal movement of the tail-bolt is limited by the distance this key is permitted to travel forwardly or backwardly in-the slot j and in the event that the continuous rods are stretched or broken or the springs disarranged or for any other reason the rigging is rendered inoperative in respect to certain of its parts the strain of the push or pull is communicated from the coupler-shank through the tail-bolt to this key g, which cooperates with the marginal flanges of the casting J.

K indicates a bottom casting which forms, primarily, a companion piece to the casting J in that it is provided with marginal flanges 70, from which project lateral lugs which are received in the seats in the draft-sills. Securing-bolts k are also employed to secure this bottom casting to the draft-sills, while a slot 1& receives the tail-bolt key 9, as shown in Fig. 3. The contiguous walls of the top and bot-tom castings J and K are so shaped as to form when assembled a longitudinal opening through which passes the tail-bolt of the coupler. In addition to this the contiguous walls are offset at their side edges to form spacesffor the passage of the draft-rods, as shown in Fig. 3. Boltsj are preferably passed through the horizontal webs of castings J and K for the purpose of securing them together. Horizontal flanges 70 extend from the corners of the bottom casting K, said flanges carrying bosses 7.0 which are countersunk in the bottom faces of the draft-sills and through which pass vertical securing-bolts k, with nuts on their lower ends impinging against said bottom flanges.

From the above it will be seen that in case repairs are needed it is only necessary to move the bottom castingK, when access will be had to the tail-bolt, the follower-plate, and the draft-springs. If it is desired to repair the continuous draft-rods, the cotter-pins can be removed and the cross-key slipped out through the lateral opening, as will be readily understood. When the draft-springs are thus uncoupled, the withdrawal of the tail-bolt key g, either in the presence or absence of the bottom casting K, will enable the couplershank and its associate parts to be moved forwardly out of position for purposes of repair or substitution.

I am aware that minor changes in the construction, arrangement, and combination of the several parts of my improved draft-rigging can be made and substituted for those herein shown and described without in the least departing from the nature and principle of my invention.

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

l. The combination with end and draft sills which are recessed on their inner faces, of a coupler-shank carrying a cross-key operating in said recesses, and draft-rods carried by said cross-key and located between the draftsills and the coupler-shank, substantially as described.

2. The combination with end and draft sills, of a cross-key, and draft-rods, mounted upon said cross-key and arranged between the draftsills, one of said draft-sills being provided with an opening for the insertion and removal of the cross-key to and from the coupler-' shank.

8. The combination with end and draft sills, of a coupler-shank carrying a cross-key, draftrods mounted upon said cross-key and arranged between the draft-sills, a followerplate, draft-springs interposed between said follower-plate and the end of the couplershank, and a casting forming an abutment for said follower-plate, said casting having longitudinal recesses in its sides for the passage of the draft-rods, substantially as described.

4. The combination of draft-sills, a couplershank located between the same, a casting in rear of the shank, a cross-key passing through said coupler shank and the ends thereof working in longitudinal recesses in the draftsills, draft-rods secured to said cross-key and located between the coupler-shank and the draft-sills, a tail-bolt for said shank, said tailbolt and draft-rods passing through channels in said casting, substantially as described.

5. The combination with draft-sills of a casting located therebetween, comprising parts J and K having in their abutting faces recesses forming channels for a coupler tailbolt and draft-rods, said part J having side projections located in vertical recesses in the draft-sills, and said part K having side projections located in said vertical recesses, and having perforated bosses K for securing-bolts and located in sockets in the under sides of said draft-sills.

6. The herein-described casting I comprising a lower part having in its upper face a recess, and an upper part having in its lower face a complementary recess, said parts having opposite slots 7' and 10 in combination with a tail-bolt working in the opening formed by said recesses, and a tail-bolt key passing through the tail-bolt and working in said slots 9' and k substantially as described.

7. The combination with the tail-bolt of a coupler, of the castings Jand K having their abutting faces formed to constitute, when together, a passage for the tail-bolt, through which said tail-bolt passes, said castings being slotted for the reception of the tail-bolt key, and marginal flanges at an angle to the body of the casing forming the ends walls of said slot for cooperating With and limiting the movement of said tail-bolt key, substantially as described.

In testimony whereof I hereunto aflix my signature, in the presence of two witnesses, this 4th day of May, 1900.

GEORGE S. MARSHALL.
