DRAFT- RIGGING- SPECIFICATION forming part of Lettersratnt Naot-57,993, dated september 1s, 190e.

Application filed January 19005 Serial.No..2,r5:82. (No model...)V

To @ZZ whom rima/y concern.- i,

`Be it known that l, PETER SOUTHER, a citizen of the United States, residing at Pine Blu, Jefferson count-y, Arkansas, have in vented a certain new and useful Improvement V1n Draft-Rigging, of whichthe follow. lng 1s a full, clear, and exact description, such as will enable others skilled in the art to,

is a crosssectional view on line 3.3, Fig. 1.-

Fig. 4 is a horizontal sectional View on line 4 4, Flg. 3. Fig. 5 is aV detail view of one of the side frame-plates, and Fig. 6 is a detaill view of the bottom frame-plate.

This invention relates to a new and useful improvement in-draft-rigging for railwaycars, particularly freight-cars, one object being to do away with the wooden draft-timbers' usually employed in freight-car draft-rigging.'

Another Objectis to enable the draft-rods of a continuous draft-rigging to be coupled closer to the draw-bar, thus obviatin g the liability of the cross-key to bend when the rods are under strain.

With these objects in View the invention consists in the construction,arrangement, and combination of the several parts of my device, all as will hereinafter be described and afterward pointed out in the claims. Y

In the drawings, A indicates the draft-sills; B, the end sill; C, the dead-Wood; D,. the coupler, and E the carry-arm, such part-s being of usual construction. The dead-Wood is preferably faced with an angle-iron L- shaped in cross-section, as shown.

My improvement consists in the provision of frame-plates constituting a housing for the rigging, which frame-plates are so constructed vas to be received by the sills of the cars as generally constructed.'

My framing consists, essentially, of two side plates and a bottom plate, said side plates being attached to and supported by the draft and end sills and the bottom plate being arranged between the lower portions of, the side plates. In Fig. 5 I have shown one offthese side platesgwhich consists of a body portion 1,whose upper edge is designed to be flushwith the top of its supportiugdraft-sill, from the outer face of which plate extends a rib 2, l(see Fig.'- 3,) affordinga shoulder which fits under the draft-sill.

j 3 indicates a4 vertical front wall which is designed to bear against the inner face of the end sill, said front wall being provided with a forwardly-extending flange 4 at its upper edge, which rests upon the 4top face of saidy end sill, asshown i-n Fig. 2. This front wall 3 is recessed or formed with a stepped portion at its lower edge, as at 5, for the purpose of permitting the forward play of the yoke,

(the end sill being cut away to receive this stepped porti'om) while a horizontal flange 6 extends in advance of said stepped portion under the end sill. The rear end of the plate is formed` with an inwardly-extending vertical flange 8, which extends nearly to the bottom of the plate.

9 .indicates a horizontal flange arranged substantially on the plane of the liange 6 and extending, preferably, throughout the length of Vthe plate and connected Vto the vertical flange 8. Flange 9. is stiffened by strengthening- Webs l0, arranged thereabove.

vllindicates a vertical flange forming an i abutting shoulder arranged beneath the flange ,9, said shoulder being strengthened by parallel webs 12, which preferably extend to the 'dange 8.

' 13 indicates a vertical flange arranged beneath iiange 9 and in advance of the flange 11, said iiange 13 affording an abutting shoulder and strengthened by webs 14, arranged in front thereof.

An elongated opening 15 is provided in the forward portion of the plate 1 for the passage of' a cross-key in the event that the rigging is of the continuous type. A series of boltopenings'l are arrangedin the plate 1, above the flange 9, forthe passage of securing-bolts, said bolt-openings being preferablysurrounded on the inner face of the plate by squared bosses, oiering countersunk seats for bolt` heads to prevent said bolts from turning when nuts are applied on their threaded ends to impinge against Vthe outer faces of the draftl sills and secure the plate in position. A series of bolt-openings 17 are arranged along IOO the lower edge of the plate. These plates are made in rights and lefts and are secu red p opposite each other against the inner faces of the draft and end sills. Bolt-openings 18 are preferably provided through the vertical walls 3 for the accommodation of securingbolt-s which pass through the end sills, and which securing-bolts may also be employed to hold the dead-wood in position.

2O indicates the bottom plate, which, as shown in Fig. G, is provided with a recess or sunken portion 2l in its upper face to acf commodate the movement of the yoke. This bottom plate has two vertical side flanges 22, designed to [it against the inner face of the lower edges of the side plate 1, said flanges being formed with openings 23, designed to register with the openings 17 of the side plates for the passage of through-bolts 24,

which tie or clamp the plate 1 against the bottom plate. 'lhe bottom face of this bottom plate is provided with transverse strengthening ribs or webs, affording seats for the bolts 24.

The draw-bar D, which may be of the usual construction, has the ordinary shank formed with shoulders d at its rearend, against which are fitted the inturned iianges of a yoke F.

Gr i ndicates a follower-plate passing through the yoke and having its ends extending laterally beyond the shank of the draw-bar, so as to rest against the abutting shoulder afforded by the vertical flange 13.

H indicates a follower-plate, which for the purpose of distinction may be designated the rear follower-plate, which extends through the yoke and has its ends project laterally, so as to rest against the vertical flange 1l.

I indicates the tail-pin of the coupler, and J the securing bolts or rivets for attaching the yoke to the draw-bar shank, one of said bolts passing through the head of the tail-pin.

vK indicates the ordinary draft-springs, interposed between follower-plates G and H and, as' usual, surrounding the tail-pin.

From the above construction it will be noted that any pressure which is exerted against the draw-bar to force the same inwardly will be initially absorbed by the draftsprings bearing against the rear followerplate H, which is held in a stationary position by the iianges 11, the associate or connected parts of the coupler moving inwardly under these conditions. Any outward pull exerted on the draw-bar will be initially absorbed by the draft-springs; but in this movement the forward follower-plate G, resting against the flanges 13, will remain stationary.

The follower-plates G and H in addition 'to having squared bearings against the rear end of the draw-bar shank and the connecting member of the yoke, respectively, are guided in their movements by the flange 9, the upper face of the bottom plate, and the side plates 1, the bearing-surfaces against these parts being preferably of such dimensions that tilting or canting of the followers is prevented, vthey being guided straight in their movements. A snug lit of the followerplates in their receiving-pockets is therefore desirable, though not absolutely necessary, as the draft-springs will hold them square against their associate parts. The construction above described is advantageous, in that it dispenses with the useof draft-timbers and olers metal wearing-surfaces to all the moving parts of the draft-rigging. Thus there are no wooden timbers to be chafed and worn away.

The housing for the rigging consists of three pieces, two side plates and a bottom plate, and in the event of accident or breakage the rigging and its housing may be quickly dismantled and the parts thereof replaced quickly and with little trouble. The arrangement of the follower-plates is such that all shocks and jars incident to coupling and uncoupling, as when the cars are switched, is taken up or absorbed by the draft-springs.

To further strengthen the housing, I may arrange blocksL behind the inner tianges 8, as is common, said blocks extending to the body-transom, or a construction preferable to the use of the blocks would be to shoulder the draft-sills A and have the side frames abut against said shoulders.

Another advantage flowing from the use of my improved rigging is the saving of the length of the cross-key M, employed in what is known as continuous draft-rigging. In ordinary constructions this cross-key is of suficient length to pass through the draft-timbers on each side of the draw-bar shank, and the continuons rods N, secured to the ends thereof, have such a leverage that the crosskey frequently bends. Further than that the slot in the draft-timbers for the passage of this key tends to weaken said timbers, and at the same time the metal key coming in contact with the wood chafes and wears it away. The side plates in my construction taking the place of the draft-timbers edects a saving in the length of the cross-key of about nine inches-four and one-half inches on each side-and the draft-rods N being short-coupled greatly decreases the liability of the cross-key to bend when the rods are under strain. Further than this the rods can be attached to the ends of the cross-keys close to the sides of the plates, as care does not' `have to be taken to prevent the rods from chang, as is done where wooden draft-timbers are employed.

I am aware that minor changes in the arrangement, construction, and combination of several parts of my device 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-
