CAST-STEEL CARRY-IRON.

' of which the following is a specification.

My invention relates to railway draft mechanism and has particular reference to a novel carry iron for supporting a car coupler in a carend sill.

It is well understood that car couplers are usually provided with a long shank which extends within the limits of the car and abuts a shock absorbing device. The car coupler usually extends through a recess in the end sill and must therefore be supported in a suitable manner at the end sill. The recess in the end sill through which the coupler shank extends is usually made of a size greater than the coupler shank to permit sidewise movement of the coupler as re quired as the cars are rounding curves. This necessitates a movement of the car coupler and a consequent wear upon the supporting member. It is desirable that the wear should be taken up by the supporting member rather than the coupler shank inasmuch as the coupler should outwear the carry iron. Therefore the carry iron should be of a softer .metal than the coupler shank. However, if a carry iron is made of such soft metal it does not provide the necessary rigidity and resistance to the shocks occasioned in service. I have conceived there fore, the idea of constructing a carry iron of cast steel whereby it may be made strong and rigid and providing "or a wear plate which plate may be of softer metal and take the wear incident to service. This wear plate may-be of exceedingly simple construction whereby it may be replaced on any repair track.

The wearingof the coupler shank or its supporting member caus the coupler to lower in its position with reference to the rail. Also the wear in service of the various parts of the truck, the perman: '=t set of the springs and the change in the camber of the car causes the coupler to lot r in its position with reference to the 1 lowering of the coupl: must he compeir sated for by the raising t tie coupler to keep it within the height p. scribed by law.

A further objecttherefolc is the provi- Speeification of Letters Patent.

sion for the easy adjustment of the height of the coupler during the service life of the car; 1st, by inserting a wearing plate of a different transverse thickness; 2nd, by inserting a liner underneath the wearing plate which isin the carrier iron at the time the adjustment is made, thuschangin'g the height of the wearing platfejiand the coupler; 3rd, by reversing a worn wearing plate and thus compensating for the change in height due to the wear in the plate A further object is to provide a carry iron which may be readily inserted or removed when necessary.

The invention will be more readily. understood by reference to the accompanying drawings, wherein, V

-Figure 1 is a plan view of my novel carry iron; Fig. 2 is an end view of the construction shown in Fig. 1; Fig. 3 is a vertical section on the line 33 of Fig. 2, and, Fig.'.4 isa perspective view of the carry iron with the removable wear plate installed.

Referring more particularly to the drawings,it will be seen that the end sill or end plate 10, is provided with outwardly projecting apertured webs 13. These webs, together with supporting bolts, formthe supports for the carry iron, which consists of a steel casting having rounded end portions 14:, apertured at 15, and between the ends provided with a web 16, forming the floor thereof. This web is bounded on both sides by the downwardly extending flanges 17 and at its corners by the upwardly extending discontinuous flanges 18. Intermediate lugs 19, form stops for the removable wear plate 20. This plate is formed preferably of wrought iron or similar material and may be of various transverse thicknesses to adjust the height of the coupler as indicated in dotted lines in Fig. 2. The coupler may also be raised by inserting liner shown by dotted line 22, underneath the old wearing plate. causing the top of the latter to be raised to the dotted line position of Fig. 2. In any event, the plate acts as a wear and adjustment plate taking up the wear and preventing excessive wear either on the coupler shank or the carry iron and providing easy means of adjusting the coupler to height. When worn it can easily be replaced or lined up or if worn on one side of the center can, if necessary, be reversed presenting a new face on the opposite side. Asa.
