DRAW-BAR PRESS.

Specification of Letters Patent.

Patented May 23, 1916.

Application filed June 16,1915. I Serial No. 34,479.

'1 '0 all whom it may concern Be it known that I, Moss Moses, a citizen of the United States, residing at Jackson, in the county of Madison and State of Tennessee, have invented certain new and useful Improvements in Draw-Bar Presses; and I I do hereby declare the following to be a full, clear, and exact description of the iiivention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention is an improved ress for use in shortening the draw bars locomotives, which become unduly lengthened as a result of the stress to which they are subjected in pulling the trains, the object of the invention being to provide an improved press of this character y means of which a locomotive draw bar may be readily shortened and which requires the services of from two to four men in its operation while the operation of shortening a draw bar, as heretofore practised, requires the services of from six to eight men.

The invention consists in the construction, combination and arran ement of devices hereinafter described an claimed.

In the accompanying drawings :-Figure 1 is a. side elevation of a draw bar press constructed in accordance with my invention. Fig. 2 is a plan of the same. Fig. 3 is a vertical longitudinalsectional view of the same. Fig. 4 is a detail elevation of the lifting hook. Fig. 5 is -a detail side elevation showing the press coupled to a by draulic power press for operation thereby. Fig. 6 is a similar view showing the press connected to an electric power press.

In the embodiment of my invention, I provide a box 1 which comprises a bottom 2 and a pair of spaced side walls 3 which rise from the bottom. A head 4 is arranged between the walls and at one end of the box. The walls are provided at the opposite end, at their upper sides, with lugs 5.

A matrix base 6 is arranged in the bottom of the press box and terminates at one end in the head 4. The upper side 7' of the matrix base is shaped to correspond with the shape of one side of a drawbar and to adapt the press for use in connection with drawbars of different forms, the matrix base is also provided in its upper side with a removable member 8. This member is arranged in a recess 9 and bears at one end also against the head 4.

lVhen the member 8 is removed the matrix base conforms to the shape of one form of drawbar and when the member 8 is in place in the recess 9 the matrix base, together with the said member 8, conforms to another form of drawbar, as will be understood. A recess 10 is in the upper side of the matrix base at the end opposite the head and the matrix base also has a transverse cross soctionally triangular recess 11 in which a lifting cam 12 1S pivotally mounted as at 13. in the recess with one side of the cam flush with the upper side of the matrix base as indicated in full lines in Fi 3. The cam may be turned to a vertica position and caused to project above the matrix base in order to lift a drawbar from the box after the drawbar has been shortened, as indicated in dotted lines in said figure.

A lever head 14 is pivotally mounted between the lugs 5 as at 15 and is connected by links 16 to a plunger 17 which is longitudinally movable in the guide recess 10 of the matrix base. A lever bar 18 may be detachably secured to the lover head by placing said bar in a socket 19 with which the leverliead is provided. The pivot shaft 13 of the lifting cam is provided at its ends with beads 20 having radial sockets 21 for the rece tion of bars 22, one of which is indicator in dotted lines in Fig. 1 and by means of which the cam may be readily turned to lift and facilitate the removal of a drawbar after the drawbar has been shortened.

In the operation of my improved press a drawbar is first heated and placed in the press, on the matrix base and with one end against the head 4, the plun er 17 having been drawn outwardly a sul'cient distance, by upturning the lever head 14. I'Vhen the draw bar has been thus arranged the lever head 14 is turned downwardly by its bar 18, thus forcing the plunger inwardly and hence shortening the draw bar between the plunger and the head 4, the inner limit of movement of the plunger being determined by the shoulder 23 the space between said shoulder and the head 4 corresponding with the required length of tho drawbar. The removable standard.

Said cam is normally arranged member 8 is provided with a recess 24 in which is an eye 25 for engagement by a hook 26, wherewith to lift said member 8 when'it is desired to remove the same.

To hold the drawbar and prevent it from buckling while being shortened in the press suitable rods 27 are provided which may be placcd'in and extended through openings .28 in the wall 3.

When'it is desired to use my improved press in connection with hydraulic electric power for operation thereby instead of manually, I remove the lever 14 and the links 16 and connect a coupling head 29 to the plunger 17 by means of a )in 30, said coupling head having a shanlr 31 for attachment to a hydraulic cylinder or electric power apparatus as shown in Figs. 5 and (3 respectively so that the press may be operated by either hydraulic or electric power.

Having thus described my invention, I claim 1. A drawbar press of the class described comprising a box, having a head at one end, and a lever head pivotally mounted at the other end, a matrix base in the bottom of the box, terminating at the head and provided in its upper side with a guide recess at the end opposite the head, a plunger arranged for movement in said recess and connections between the plunger and the lever head to enable the plunger to be operated by the lover head.

2. In a drawbar press a press box, ahead therein, a matrix base, a plunger, means to operate the plunger and a lifting cam arranged in a recess in the upper side of the matrix base said lifting cam having a shaft iivotally mounted in the walls of the press ox and provided at its ends with means whereby said cam may be turned.

3. In a drawbar press a press box, a head therein, a matrix base, a plunger, means to Ooptu oi this patent may be obtained for two cents each,

operate the plunger, said matrix base having a detachable member in its upper side 'corresponding with one form of drawbar,

the recess corresponding with another form of drawbar.

4, Adrawbar press of the class described having a matrix base, a head in one end of the base, a shoulder at the other end of the base, a plunger, and means by which the plunger maybe operated, said shoulder limiting the inward movement of the plunger.

5. A drawbar press of the class described having a matrix base, a head in one end of the base, a plunger at the other end of the base, operating means for the plunger, and means to prevent the drawbar from buckling while being subjected to pressure by the plunger. 7

6. A drawbar press of the class described having a matrix base, sides rising vertically frointhe base, a head located between the sides at one end of the base, the opposite end of the base having a recess, a shoulder at the end of the recess, a plunger slidably mounted in said recess, a lever head pivotally mounted to and between the sides at said other end of the base, and a link connected to the lever head and plunger, said shoulder limiting the inward movement of the plunger.

7. A drawbar press of the class described having a matrix base, stationary sides rising vertically from the base, a head located between the sides at one end of the base, a plunger slidably mounted between the sides at the other end of the base, and means by which the plunger may be operated.

In testimony whereof I afiix my signature in presence of two witnesses.

MOSE MOSES.
