DRAFT-GEAR CARRIER.

Patented Jan. so, for a.

To all whom it may concern:

-Be it known that I, JOHN ALLISON, a resident" of Dravosburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Draft-Gear Carriers, of which the following is a specification.

This invention relates to draft gear carriers for railway cars, and more particularly to cast steel draft gear carriers for cars having wooden center sills located above the body bolster, although it may be also applied to cars with metal sills.

The object of the invention is to provide a draft gear carrier of this kind, which can be made of a single integral member employing a minimum amount of metal and thoroughly reinforced and strengthened throughout, so that it is strong and rigid and very light for its strength; one which distributesthe strains on the car frame between the end sill, center sills, body bolster and other framework; one which has a rearward extension from the body bolster in the form of a strong, hollow box girder whose rear end portion may be in the same horizontal plane with the body bolster and is attached to the center sills, so that it transmits directly the longitudinal pull or thrust and the upward thrust directly to the car frame; one which can be adapted for various types of body bolster and draft gear; and one which can be inserted into place without requiring removal of the trucks.

Other objects of the invention are in part obvious and in part will appear more in detail hereinafter.

The invention comprises the draft gear carrier hereinafter described and claimed. In the drawings, Figure 1 represents a plan view of one form of draft gear carrier embodying the invention; Fig. 2 is a longitudinal sectional elevation, of a similar draft gear carrier, the section being taken on a plane corresponding to the sectlon line 2-2 in Fig. 1, and showing a modified form of king pin opening; Fig. 3 is a cross section on the line 33, Fig. 2; Fig. 4; is a half cross section on the line M, Fig. 2; Fig. 5 is a. half end view showing the support for the movable carrier bar; Figs. 6 and 7 are detail views of the connection to the bolster and showing a modification; Fig. 8 is a plan 'view corresponding to Fig. 7 and Fig. 9

is a detail view showing a modification.

The draft gear carrier shown in the drawings is a hollow cast metal member formed of a single piece of metal and having many of the characteristics of a box girder, so that it is exceedingly strong and rigid and yet is of minimum weight. The front portion of said carrier has two opposite vertical side walls or members 1 which are spaced apart to receive the draft gear, not shown, but which may be of any suitable type. If the draft gear is of the usual spring and follower plate construction the side walls 11 of the carrier are preferably provided on their inner faces with inwardly projectin lugs or ribs 2 for guiding the springs and maintaining them in central position in the carrier. In some types of draft gear laterally extending spring supporting devices are utilized, and to accommodate such gears the side walls 1 may be provided with central openings 8, so that the gear supporting members may extend through or outside of the side walls or members of the draft carrier. The side walls may also be provided with downwardly extending integral pockets 3 to receive transverse gear supporting bars 4. Said walls are also provided with inwardly extending portions 5 for confining the front andrear follower plates, as is usual, and said inwardly extending walls may be provided with depending pockets 6 for receivin the longitudinal gear sup porting bars The follower plates are confined against upward movement in the draft gear carrier by inwardly extending horizontal walls or flanges 9, which form a housing for the draft gear and partially inclosethe same. These horizontal walls, at or near their front ends, are connected by an integral transverse member 10, which forms a cross connection between the side members of the carrier and reinforces and strengthens the same. Particularly when the draft gear pocket is long the resistance to spreading of the side arms or members 1 may be further increased by one or more supplemental 40 receiving the transverse draft gear carrierto be inserted from beneath without removing the trucks, the front wall of the transverse member 10 may be inclined forwardly and downwardly, as shown at 12, the end sill 11 being beveled to correspond. When the draft gear carrier is pushed up into place over the body bolster thetransverse member wedges in behind the end sill and is therefore very solidly connected to the car frame. The same effect can also be obtained without resorting to an inclined wall or beveling the end sill by'inserting a shim 13 between the end sill and transverse member 10 after the draft gear '%arrie)r is pushed into place, as shown in The draft gear carrier is also arranged to transmit pulling strains to .and receive bufling strains .from the usual end bulfer 14, located in advance of the center sill 11.

This end buffer is shown as an integral portion of the draft gear carrier itself, so that it forms an additional strengthening cross tie, but it may be a separate member riveted or bolted-thereto and to the end sill, as at 14, in Fig. 9. In this case the side--members 1 of the draft vided with vertical shoulders 15 lying behind the end bufler. Consequently, in both forms of carrier 'buflingshocks are transmitted directly from the end buffer to the carrier and distributed to the car frame, as

. will 'be readily understood. I

The frontportions of the sidewalls 1 of the carrier'are somewhat closer together than those portions opposite the spring pocket therebetween, as is usual. These" portions of the side walls maybe provided with longitudinal slots or'o enings 16 for dra t gear keys for securing the draw bar to the draft gear. Also, near their front ends the side walls or members 1 of the draft gear carrier are provided with longitudinally spaced, inwardly 5 extending integral brackets 17 to receive a' suitable swinging support for, the movable 'carrier bar. As shown, this support is a transverse bar- 18 having bifurcated hookshaped'end members 19 carried by the lower cross bar 20 ofan I-shaped link 21 having upper cross bar 22 fitting in the brackets 17 from side to side with the carrier bar bu prevents it from dropping down.

This draft gear carrier is intended particularly for use with cars embodying the usual wooden center sills, such as indicated at 23. The upper horizontal walls 9-of members '1 are therefore provided with upe0 wardlgextending parallel vertical flanges 24 provi zontal The a rearward extension 25, which is d,with openings for receiving horibolts passing through the center sills.

. bolster provided with gear carrier are pro-.

The cross bar 18 .is thus capable of swinging draft gear carrier is also provided with c v generally of theform of a hollow box girder, narrower than the front portion of the carrier, I i

so that it fits between the two wooden center sills and whose side walls 26 are continuations of the walls 24. These side walls 26 are also provided with horizontal bolt holes for attaching the carrier to the center sills, said side walls being connected by upper and lower cross webs or

members

27 and 28. v

It curves upwardly from the spring pocket to a position above the body bolster, and be-.

extending horizontal flanges 30 having bolt holes for securing them to the bottom faces of the center sills, and said horizontal flanges may also have portions 31 above the body orbolting them thereto- Bolt holes 33 may also be provided in the horizontal portion of the rearward extension above the body bolster. Consequently, the draft gear carrier may be very firmly and rigidly secured both to the center sills and body bolster.

The upper and lower horizontal walls of the rearward extension, above the body bolster, are preferably also provided with alined openings 34 for receiving thev king pin, and if desired, these openings may be oblong or elongated, asat 34, Fig. 2, to adapt the carrier for diiferent types of body bolster and for different distances between the body bolster and the end of the car. For. example, Figs. 2 and'6 indicate respectively at 29 and 36 the upper plates of two different forms of body bolster, 'andhaving openings for the king pin at opposite ends openings for riveting of the elongated openings 34. In Fig. 2 the i can be utilized for transmitting the thrust of the draft gear carrier to a narrower bolster, and hold the bolster in the proper-position for receiving the king pin. By properly locating these lugs the 'carriermay be adapted for any type of body bolster, and may be subsequently adapted'for a wider bolster by chipping off or otherwise removing first one set and then the other set of said lugs.

The rear end carrier is provided with a transversely exportionof the draft geartending vertical web portion 41 connecting its side walls. The rear end portion 42 of the upper horizontal wall of said member may be riveted or otherwise secured to a suitable transverse member 43 lying under and secured to the center sills 23. Consequently, the upward thrust of the rear end of the draft gear carrier is transmitted to the center sills. The vertical web 41 may be taken advantage of for transmitting the longitudinal thrust of the draft gear carrier to the center sills, by making the transverse member 43 an angle iron or Z-bar whose vertical web receives the thrust from the web 41 and allslo abuts blocks 23 fastened to the center si s.

The rear extension of the draft gear carrier is open on its bottom, its side walls being connected at the bottom only by the transverse member 28 near the spring pocket and also above the body bolster, the bottom openings therein providing access to the interior of the carrier for fastening attachments thereto. Beyond the body bolster the downwardly extending rear end portion of the carrier may also be provided with horizontal outwardly extending flanges 44 for atltiachment to the lower faces of the center s1 s.

To adapt the carrier for use with steel center sills which do not extend the full length of the car the side walls of the rearward extension may also be provided on their outer faces with lugs or projections 50 forming vertical shoulders to abut the ends of said sills and transmit longitudinal strains thereto.

This draft gear carrier is very light for its strength and consequently can be made at comparatively low cost. It has all the usual functions of draft gear carriers and in addition distributes the strain over the entire car frame so that the wear and tear thereon is reduced. It may be lifted into place from beneath without removing the car trucks, by pushing the rearward extension up over the body bolster and after it has been pushed fully back, lifting the frontportion of the draft gear carrier and securing it to the center-sills. Consequently repairs and replacements are readily effected without special equipment. The draft gear carrier also may be adapted for any style of car or any type of draft gear.

It will, of course, be understood that the invention is not limited to the precise form of carrier shown in the drawings, but admits of considerable modification within the scope of the appended claims without departing from the spirit of the invention.
