DRAVJBAR CARRY IRON.

Application filed February 25, 1924. Serial No. 695,019.

T 0 all whom it may concern.

Be it known that I, Josnrn Moonn, Jr., a citizen of the United States, residing at Freeport, in the county of Stephenson and State of Illinois, have invented certain new and useful Improvements in a Drawbar Carry Iron, of which the following is a speciication.

This invention relates to improvements in stirrups or carry iron constructions for the draft gear of railway rolling stock.

The primary object of this invention is the provision of improvements in draw bar or draft gear carry iron or stirrup constructions which includes a novel carry iron construction which may be conveniently attached or detached with respect to the striking plate.

A further and important object of this invention is the'provision of a relatively simple and easy operated stirrup or carry iron for the draft gear of rolling stock which includes an easily detached carry iron member normally held into locked relation with a striking plate by means of a releasable lat-ch mechanism which may be conveniently operated without the loss of any parts.

Other objects and advantages of the improved stirrup or carry iron construction will be apparent during the course of the following detailed description.

In the accompanying drawings, forming a part of this specification, and wherein similar reference characters designate corresponding parts throughout the several views.

Figure 1 is a front elevation of the improved stirrup showing the position of the same upon the beam of a car, and in assembled relation for movably supporting a draw bar.

Fig. 2 is a plan view of the details illustrated in Figure 1.

Fig. 3 is a front elevation, partly in cross section, showing cooperating details of the improved stirrup, more particularly illustrating the manner in which the latch or bolt means may be operated to permit the removal of the carry iron member with re spect to the striking plate.

Figs. 4, 5 and 6 are cross sectional views taken on their respective lines in Figure 3 of the drawings.

Fig. 7 is a fragmentary perspective view of substantially a half portion of the body or striking plate, and

I Fig.5 is a'perspect-ive view of the preferred form of carry iron associated with this invention.

In the drawings, wherein for the purpose of illustration is shown but the preferred embodiment of this invention, the letter A may generally designate the improved stirrup or draft gear support which is adapted for attachment upon the end sill of a car or other piece of rolling stock C to properly support the draw bar D of suitable draft gear thereon. This stirrup or strap includes a striking plate E; carry iron F; and means G for latching of the carry iron member F with respect to the striking plate E.

The stirrup body or striking plate E is constructed of metal, and includes the. attaching flanges or feet 10 and 11 adapted to overlie the under or side surface of the car sill B for attachment to the latter by means of bolts 12. The striking plate also includes the downwardly projecting arms or

stationary jaws

13 and 14 which provide a slot or opening 16 therebetween within which the draw bar D and carry iron F are received. The side surfaces of the slot 16, which are in fact the facing surfaces of the arms or

projections

13 and 14 are provided with the substantially L-shaped recesses 15 therein, and an end of each of said recesses opens on the front surface of the jaw or arm in which the recess is formed; the recess then extending downwardly along the jaw or arm 13 providing a recess portion 15" adapted to receive an end of the carry iron F, as will be subsequently described.

The carry iron member F is of durable metal, and of relatively simple formation providing a body portion 20 with the

end extensions

21 and 22 adapted to be received in the recesses 15 and to rest in the lower socket portions 15 of said recesses when the carry iron is in place. When so positioned the carry iron F is supported by the jaw or arm portions 13 and 1 1 of the striking plate E and the carry iron cannot become laterally displaced but must first be lifted in the recesses 15 in order to dislodge the same therefrom; this being due to the L-shaped formation of the recesses, and as is illustrated in Figure 6 of the drawings.

Referring to the latch construction G as used in connection with the improved stirrup A the same preferably contemplates the provision of a pair of slidable bolts 25, slidable within sockets 26 provided therefor inwardly from the endsof the carry iron mem berF. These bolts or latch members 25 are of novel formation, including the bolt head 27 at one end; and the cylindrical body 23 with an annular groove 29 provided there in adjacent the end opposite the head 27. The latch members or bolts 25 are slipped into their sockets 26 so that the heads 27 lie adjacent the outer ends of the carry iron F. A spiral compression spring 31 is employed with each bolt 25, receiving the body portion 28 of the bolt therein and engaging the head 27 at one end and at its other end engaging against an annular shoulder provided as a part of the carry iron socket 26. The springs 31 normally act upon the latch members 25 to force the bolt heads 27 thereof outwardly from the end surfaces of the

carry iron extensions

21 and 22. Suit able transverse keeper openings 35 are provided through the jaws or

arms

13 and 14 of the striking plate E, into which the bolt heads 27 extend to lock the carry iron into assembled relation with the arms 13 and Ll of the striking plate E, and will be apparent to those skilled in the art to which this invention relates.

The normal operation of the latch device G is such that the members 25 are urged b the springs 31 into a locking relation with the striking plate. To prevent accidental displacement of the latch bolts 25 from this position, suitable retaining pins 40 are employed, and may be attached by means of flexible chains All to the carry iron, so that they may be moved for insertion through transverse openings 44 provided through the carry iron. These retaining pins are each provided with a reduced end 45 adapted to cooperate against the end surface of the body 23 or in the annular groove 29 in order to either retain the latch member or bolt 25 in a locked relation or in an unlocked relation with respect to the parts of the stirrup A.

Referring to the operation of this invention, and assuming that the carry iron is detached from the striking plate, in order to assemble the carry iron in the striking plate it will be necessary to maintain the latch bolts 25 in a withdrawn position within their sockets 26. To permit this the latch members 25 are forced inwardly of their sockets 26 and the pins 40 are then inserted through their openings 44 until the reduced ends 45 of said pins 40 engage in the annular grooves 29, and said pins 40 will thus hold the bolts or latches 25 in the withdrawn position which is illustrated in the cross sectional view of Figure 1, for the left hand latch device. The carry iron may then be assembled conveniently and quickly into the recesses 15 into the position above defined. When the carry iron is at rest in the bottom portions 15 of the recesses 15 the socket 26 will be in alignment with the transverse openings 35 through the

arms

13 and 14 of the striking plate. Uponwithdrawal of the pins 40 the latches or bolts 25 will then be thrown by their springs 31 into the openings 35, and the carry iron will be locked against relative movement with respect to the striking plate. It will then be desirable to lock the bolts against accidental movement, and this result is attained by again inserting the pins 10 until the reduced portions 45 engage the ends of the body portion 28 of said bolts 25, substantially in the position illustrated by the right hand latch mechanism in the cross section view of Figure 41-. The carry iron and its striking plate being in assembled relation with the bolts locking the former in the latter, the bolts 25 may be depressed into their sockets 23 by means of a suitable post or tool 50 which is inserted in the transverse openings 35 to act upon the bolt heads 27 to effect depression, substantially as is illustrated in Figure of the drawings. lVith the carry iron in place in the striking plate the same forms a support for the draw bar D, as will be readily understood by those skilled in the art to which this invention relates.

From the foregoing description of this invention it is apparent that a relatively simple and easily operated type of stirrup for the support of draw bars of draft gear has been provided, in which the carry iron member may be readily attached or detached with respect to the striking plate, without the necessity of unscrewing bolt nuts, and the taking out of cotter pins, as is now the case with carry iron constructions, and with which there is much waste when it is desired to disassemble the draw bar therefrom. The improved stirrupis economical, costs little for maintenance, is labor saving, easily operated, is absolutely safe in operation, and does not entail loss of parts incident to disconnection.

Various changes in the shape, size, and arrangement of parts may be made to the form of invention herein shown and described, without departing from the spirit of the same or the scope of the claims.
