SPECIFICATION forming part of Letters Patent No. 622,056, dated March 28, 1899. Application filed August Z2, 1898. Serial No. 689,174. (No model.)

To all 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 a certain new and useful Improvement in Draft-Rigging, of which the following is a full, clear, and exact description, such as will enable others skilled in the artto 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 a longitudinal vertical sectional view through a portion of a car, showing my improved draft-rigging in position. Fig. 2 is an inverted plan view thereof, and Fig. 3 is a rear elevational view of lthe follower-plate.

This invention relates to a new and useful improvement in draft-riggings for railroadcars, the objects being to strengthen said rigging, so as to resist the shock orimpact while coupling, to dispense with the use of drafttimbers, whereby the continuous-draft rods, if such are employed, can be attached to the cross-key close to the sides of the draw-bar, and to provide a casting to take the place of the draft-timbers, which castin g forms the follower-plate and also acts as a support for the draft-rods. 'Vhen ordinary draft-timbers are employed, the same have to be slotted to permit the cross-key to pass therethrongh and the continuous-draft rods have to be secured to said cross-key outside said timbers,-which construction is objectionable in that the frequent movement backward and forward of said continuous-draft rods soon wear, by rubbing or chafing, the sides of the draft-timbers to such an extent that these timbers have to 'be frequently renewed. When new timbers are introduced, t-he rubbing contact of the draft-rods therewith is objectionable, and this draft rods; third, in the novel construction of the casting employed, whereby the drafttimbers are dispensed with and I am enabled to place the continuous-draft rods closer together and by so doing shorten the cross-key and form a more compact structure than could be accomplished it' said draft-timbers were used, and other features reside in the novel construction, arrangement, and combination of the several parts, all as will hereinafter be described,-and pointed out in the claims.

In the drawings, A indicates the end wall of a car-body; B, the end sill; O, the draftsills; D, the dead-wood E, the shank of a coupler; F, the cross-key, which passes through the rear end of the coupler-shank, on the ends of which cross-key are arranged the continuous-draft rods G of what is known as the American continuous-draft rigging, H, the tail-bolt of the coupler; I, the follower-plate, and J the tie-rods, which pass through said follower-plate and through the end sill and dead-wood. This follower-plate is practically in the form of a bracket and is preferably a metallic casting, which consists of a base l, from which depends, preferably from its forward end, a vertical member 2, said member being preferably somewhat thicker than the balance of said follower-plate, whereby a greater bearing-surface will be presented to the several members which pass therethrough. From the upper face of said base rise suitable lugs 3, preferably two in number, so placed as to rest against the inside faces of the draftsills, to which they are secured by means of a through-bolt 4. l

5 indicates an opening through the vertical member 2, which is designed to receive the tail-bolt of the coupler.

6 indicates openings or grooves in the outer edges of the verticalmember 2, designed to receive andA support the continuous-draft rods.

7 indicates openings formed in the member 2 to receive the rear ends of the tie-rods G, said openings being preferably axially coincident with said tie-rods.

8 indicates strengthening webs or braces designed to reinforce the member 2.

9 indicates a suitable boss formed around the rear face of the openings 7, whose rear face is formed at right angles to the pitch of IOO said opening in order that the head or nut of. l

the tie-rod G will be provided with a full bearin g-face, which would not be the case if said boss were omitted, as will readily be understood.

The strengthening-webs S are preferably formed directly in longitudinal alinement with the tie-rods G for the purpose of strengtheningthe castingon theline of greatest strain or impact, and consequently the lower end of said webs terminate in the boss 9, as is clearly shown in Fig. 3.

The upper face of the base l of the followerplate outside the lugs 3 is designed to be placed against the draft-sills C and said follower-plate secured thereto, through the medium of said lugs 8, by the bolt 4, as before mentioned, and in addition ro this, in order to insure a more substantial fastening for said follower-plate, I provide bolts l0, which pass through said base 1 and through said draft-sills, firmly securing said follower-plate in position.

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

Having thus described my invention, what I claim, and desire to secure by Letters Patent, isfl. The herein-described casting for use in draft-rigging for cars, the same comprising a base-plate above which rise lugs for engagement with the draft-sills, and from which depends a follower-plate formed with an opening for the tail-bolt, said follower-plate being, also, formed with recesses in its sides to rcceive and support draft-rods, and reinforcingwebs, substantially as described.

2. rlhe herein-described casting for use in draft-rigging for cars, the same comprising a base-plate l, parallel lugs 3 rising from said base-plate, a follower-plate 2 provided with a central aperture 5, notches 6 in its side edges, and obliquely-disposed openings 7 strengthening-webs 8, and bosses 9 around the openings 7, substantially as described.

3. The combination with the draft-sills and end sill o a car, of a coupler, a casting comprising a base-plate l, arranged under the draft-sills, parallel lugs 3 rising from said base-plate, bolts 4 and l0 for securing the casting to the draft-sills, a follower-plate 2 depending from said base-plate of the casting, said follower-plate being formed with an opening for the passage of the tail-pin of the coupler, and notches for the reception and support of draft-rods, strengthening-wcbs 8, and rods for tying the lower edge of the follower to the end sill,substantially as described.

In testimony whereof I hereunto affix my signature, in the presence of two witnesses, this 20th day of August, 1808.

GEORGE S. MARSHALL.
