DRVB'-CENTEBIG DEVICE AND CARRIER.

To ZZ whom. it may concern:

lle it known tha't 1, .loi-1N R. MITCHELL, a citizen ot the United States, residing' a Evanston, in the county of Cook and State or' lllinois, have invented a certain new and useful improvement in Draw-Bar-Centering levices and Carriers. of which the follow-I ingr a full, clear, concise. and exact description, referencebeing had to the companying drawings, 'forming a pari this speeication.

This invention relates to improvements in a draw-bar centering device and carrier.

The o'lvject ot the invention is to provide simplified means tor automatically fnaintainingj a draw-bar in central position which means are also so arranged that they support 'the carrier for air, steam or electric` automatic connectors.

The invention furthermore consists in the improvements in the parts and devices, and in the novel combinations ot the parts and devices herein shown, described or claimed.

` forming a part of this In the drawing specification, Figure 1 is an end elevation of a portion of a car showing my improvement in connection therewith. the coupler shank beingi shown in section. Fig. 2 is a vertical sectional view taken on the line f2 of Vig. 1. Fig. 3 is a detailed seo tsonal'vieiv showing;r a niodiiied form of attachment between the centering device proper and the carrier tor the automatic air. steam 0r electric connector. Fig'. i is a view similar to Fig. 1 showing a diierent embodiment of my invention, and lig. 5 is a 'vertical sectional view taken on the line of Figi. 4.

\ lu said drawing and referring* to Figs. 1 and 2. 1() denotes a horizontal strap or bur at the end ot' a car and rigid with the car under-frame, To said bar is secured a carrier iron l1 by bolts 12, or other suitable means, the carrier iron being arranged to slidably support the draviubar shank 13. Secured to the underside of' the carrier iron l1` near tl" ends thereof., are angles 121--14 'in which is supported and mounted a bolt 15, kept in place bv a head on one ond and nut 1G on 'the other end. Tlv angles lli-J i serve as stops for a. pair ol einge l7-- i7 mounted. on said bolt l5. lhe carrier iron il errang/*vd to slu'iport, a centering member i; biw'lwt 18 which,

as shown, is provided with two sets of spaced upwardly extending,r earsthat are arranged 4to engage the sides ot the drawbar shank. Mounted between each pair of spaced ears 19 on a suitable pin or bolt 20 is an anti-friction roller 21, which rides on top of the carrier iron 11 and which thus permits the member 18 to slide back and forth with a minimum amount of friction. At its underside the member 18 is formed with two semi-cylindrical chambers 22 divided by a central vertical partition 23, the inner ends ot' the springs 1?-17 being seated in said chambers as will be understood. To the under cylindrical side 21A of the member 18 is adjustably secured a carrier 2. having a correspondingly curved top flange 2G arranged to be bolted to the member 18, the bolts 27 for this purpose being adjustable in elongated slots 28 in the member 18 vvl'iereby the carrier 25 can be adjusted to the proper angle. 'The carrier 25 supports tho automatic air and steam and electric connector and may be ot any desired form, that shown in the drawing illustrating 'one well-known type which l do not deem it necessary to here describe.

From the preceding description, it will be seen that the member 18 will cally retained in central position by means of the springs 17 i-17 and consequently the draw-bar 13 .vill also be kept in central position as will the carrier 25. This is of importance since in connecting or coupling tivo cars together I:he automatic coupler or connector for the air, steam and electric conductors will always be positioned in line with the coupler, and when the train o cars is passing over a curved track, the steam and air pipes will be also kept in vertical alinement with the couplers and be caused to autonntically tollow the movements thereof at all times.

1n Fig. 31 have shown a dilierent method of connecting the carrier with the centering device proper and as so showm the centering member 11S is provided with-a (.lepending centrally located tlange 31 having an elon gated horizontal slot 32 therein. he car' rier 125 is provided with a pair of upstanding flanges 126 adapted to sti-addio the flange 3l and be secured thereto by bolts 127 which pass through the slot 32.

ln the construction shown in Figs, i and be automati- 5, 211 denotes the carry iron, 213 the draw bar and 218 the centering member for the air, steam and electric automatic connector. The member 218 is substantially of inverted U-shape in cross section as clearly shown in Fig. 5 and thereby adaptedl to straddle the carry iron 211. At its ends the member 218 is provided with upstanding shoulders 219--219 arranged to engage the sides of the draw-bar shank. In this construction, the carrier 225 is supported vby means of a member 226 and pivotally mounted links 2274227, the latter being supported at their upper ends on pins or bolts 228- mounted in the depending side flanges of the member 218 and pivotally connected' at theirlovver ends by bolts 229 supported in the npstanding side walls of the member 226. The carrier 225 is connected to the member 226 by means of bolts 230-230.

In the construction shown in Figs. 4 and 5 and herein above described, it is apparent that thc automatic connector for the air, steam and electric conductors will followthe movements of the draw-bar since the member 218 will always be moved in accordance With the movements of the drawbar. In addition, the connector is flexibly connected With the member 218 and may thus accommodate itself to various conditions 1n service.

I claim:

1. In car construction, the combination with a draw bar, of a carry iron beneath the draw bar and arranged to directly support the latter, a member having antifriction rollers, slidably mounted with respect to said carry iron and supported thereby, said member having upstanding projections on each side of the draw bar shank adapted to engage the latter, and spring means for normally maintaining said member in central position.

2. In car construction, the combination with a carry iron' adapted to support the Weight of a draw bar, of a member slidable with respect to Said carry iron and having upstanding shoulders located at the sides of the draw bar shank, a carrier for air and steam automatic connector secured to said member, and means for adjustably securing said carrier to saidl member in any predetermined position.

In Witness that I claim the foregoing I have hereunto subscribed my name this 22nd day of April 1915.

JOHN njMiTcHELL.
