UNITED STATES. PATENT OFFICE. ROBERT S. HAMMOND, OF CHICAGO, IIrLINOIS, ASSIGNOR TO AMERICAN STEEL FOUNDBIES, OF CHICAGO, ILLINOIS, A CORPORATION OF NEW JERSEY.

CARRIER-IRON.

Specification of Letters Patent.

Application filed June 11, 1917. Serial No, 173,998.

To all whom it may concern:

Be it known that I, ROBERT S. HAMMOND, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Carrier-Irons, of which the following is a specification. My present invention relates to improvements 1n carriers for various purposes and more particularly for couplers for railroad rolling stock.

The principal objects of my present invention are to provide a unitary carrier, to

' provide an improved form of carrier which may be secured to the striking casting or between the draft sills without the use of any additional devices such as ins, cotters, nuts, bolts or the like and wit out the use of tools of any kind; to provide improved means for preventing the disengagement of the carrier with the striking casting, to rovide a carrier adapted for use with stri ing castings for new cars, or economy draft arms or other draft arms for old cars, and generally to improve, simplify and cheapen the construction of carriers and striking castin s and the parts associated therewith.

in attaining these and other objects and advantages to be hereinafter set forth, I have provided a construction two embodiments of which are illustrated in the accompanying drawings, in which Figure 1 is a front view, parts being in section, of the carrier and the parts of the striking casting engaging therewith;

Fig. 2 is a section on the line 22 of Fig. 1.

Fig. 3 is a section on the line 3-3 of Fig. 1;

Fig. 4 is similar to Fig. 3 and shows the carrier in position to be disengaged from the striking casting;

Fig. 5 is a side view of the construction shown in Fig. 1, taken from the left hand side; and

Fig. 6 is a plan view of a modified form of construction.

Considering first the form of construction shown in Figs. 1 to 5, the carrier consists of a single casting 10, having its ends carried in apertures 11 and 12 of the

side portions

13 and 14 of the striking casting.

The carrier and these apertures in the striking casting are so constructed relatively to each other that when the carrier is in the position shown in Fig. 1 it cannot move longitudinally with respect to the striking casting, but when lifted it can be moved mto or outof engagement with the striking casting. The dimensions of the ends of the carrier and the aperture aresuch that the carrier may be placed in position and removed w1t in the limit permitted by the clearance of the coupler between it and the top of the striking casting when the coupler is in its normal position.

It will be seen that the carrier comprises four projecting ortions which engage the walls of the stri ing casting on one side or other of the apertures 11 and 12. The proecting portions are respectively 15, 16, 17 and 18. It will be seen on inspection of Figs. 2 and 5 that the projection 15 prevents movement of the carrier toward the left and the carrier as will be described later is disengageo from the striking casting by movement to the right. The projecting

portions

16 and 17 gri striking casting there etween. The part 18 engages the part 19 of the striking casting. By lifting the left-hand side of the carrier and simultaneously moving it to the left as shown in Fig. 3, the right hand portion 20 of. the carrier may be moved clear of the projection 21 so that the part 17 may be lifted into the position shown in Fig. 4 in which position the

projections

18 and 16 are brought into register with the

lateral extensions

22 and 23 of the aperture 12. In this position the carrier may be withdrawn.

Patented Dec. 17, 1918.

i the part 21-of the Therefore, to disconnect the carrier member from its normal locked position, as shown in full lines in Fig. 3, the left-hand side 'of the carrier member, as viewed in said figure, is tilted upwardly about a longitudinal axis thereof, the carrier member then moved bodily to the left, the right-hand side of the carrier'member then tilted upwardly about a longitudinal axis thereof, and then moved bodily longitudinally far enough to disconnect the left-hand end of the carrier member, as viewed in Fig. 1 from its seat, whereupon that end of the carrier member may be lowered and the other end withdrawn by a reverse bodily movement to the left. Due

to the necessity of these various releasing movements of the carrier member, it is apparent that it cannot be accidentally disengaged as a result of jolts incident to service conditions.

The part 20 of the carrier is the surface of the carrier toenable the carrier to be removed within the clearance allowed between the top of the coupler and the striking casting. It will be observed that the aperture 11 is made of considerably greater height than the thickness of the carrier 10 so as to allow the carrier to be tilted in one direction as shown in Fig. 3 and then in the opposite direction as shown in Fig. 4: in order to bring the carrier into disengaging position.

The method of inserting the carrier into the striking casting is, of course, the exact reverse of the-method of removing it.

In order to facilitate the insertion or removal of the carrier the recesses 24 are arranged in one end of the carrier adapted to act .as hand holds for gripping the end of the carrier. The central portion of the carrier is raised to substantially the height that the upper surface of a centering device would have were one used. This construction is adopted with a view to enabling the striking casting to be equipped either with a carrier or with a combined carrier and centering device. It will be understood however that the central portion may be not raised, but may lie in the same plane as the end portions.

The raising of the central portion of the carrier produces shoulders 25 which prevent (with the size of aperture shown) the carrier being withdrawn as a whole through the aperture 12. Consequently after the carrier has been moved toward the right sufficiently far to bring its left hand end out of engagement with the aperture 11 that end of the carrier is dropped and then the carrier as a whole is moved downwardly toward the left in order to bring the other end of the carrierout of engagement with the striking casting. It will be observed that the lower edge of the part 13 of the striking casting is beveled at 26 to facilitate passage of the carrier thereby. Similarly, the upper edge 27 of the aperture 12 is beveled for the same purpose.

It will be observed that the ends of the carrier are shaped differently so that the carrier cannot be placed in position wrong end to. In the form of construction illustrated, one end is made wider than the other so that the ends cannot be reversed relatively to the striking casting.

In the modification shown in Fig. 6 the carrier has no raised center portion and can therefore be withdrawn through one aperiasaera ture as can also be done with the device shown in Fig. 1 when it is made fiat, that is, without the raiscdportion. The projecting

parts

28, 29 and 30 being brought out of engagement with the walls of the aperture 31 in exactly similar manner to that described in connection with Figs. 3 and 4.

Having thus described my invention and illustrated its use, what I claim as new and desire to secure by Letters Patent is:

1. A device of the character described comprising in combination a supporting member, a carrier member, said supporting member having apertures adapted to receive the ends of said carrier member, and projecting portions on said carrier member adapted to normally engage opposite faces of said supporting member and thereby prevent accidental longitudinal movement of said carrier member relatively to said supporting member and being disengageable from said faces by a tilting movement of the carrier member about a longitudinal axis thereof and being removable from the supporting member by a longitudinal movement.

2. A device of the character described comprising in combination a striking member, a carrier member, said striking member having apertures adapted to receive the ends .of said carrier member, and projecting portlons on said carrier member adapted to enends of said carrier member, and projecting.

portions on said carrier member adapted to engage opposite faces .of said striking member, one of said apertures being of greater height than the thickness of said carrier and having on one side a lateral extension adjacent its upper part adapted to allow of the passage of said projecting portions when the carrier member is lifted, and on the other side an inwardly extending projection adapted to check such lifting movement and thereby prevent accidental disengagement of said carrier and striking members.

4. A device of the character described comprising in combination a supporting member, a carrier member, said supporting member having apertures adapted to receive the ends of said carrier member and interlocking portions on said carrier and supporting member disengageable by not less than two separate tilting movements of the carrier member about longitudinal axes thereof, whereby accidei iei iongitudinal movement of said carrier member is prevenied.

5, A device of the character described comprising iii combination a supporting member, a carrier member, said supporting member having apertures adapted toreceive the ends of said carrier member and inherioeking portions on said carrier and supporting member disengageable by not less than three separate movements, two of said movements of the carrier member being about longitudinal axes thereof, whereby accidental longitudinal movement of said carrier member is prevented.

carrier member about longitudinal axes thereof, whereby accidental longitudinal movement of said carrier member is preventedi.
