UNITED STATES ALEXANDER METTRAS, OF DE BEQUE, COLO RADO.

JACK AND LIKE moor.

Application filed February 14, 1924. Serial No. 692,814.

To all whom it may concern:

4 Be it known that I, ALEXANDER siicrrnns, a

citizen of the United States, residing at De" Beque, in the county of Mesa, State of Colorado, have invented certain newan'd useful Improvements in Jacks and .like Tools, of which the following is a specification.

The present invention relates to a special form of jack or like tool.

More particularly theinvention relates to a new and improved tool especially adapted for use in. connecting and disconnecting rail joints or connectors of the type disclosed in U. S. Patent Number 1,499,836, issued July 1, 1924.

The object-s of the invention are to provide a new and improved tool and mechanism of the character described, and such other objects as may be attained by use of the device and principles thereof as set forth in the following disclosure of a preferred embodiment of the invention, of which:

Fig. 1 is a view showing the jack applied to use in assembling the rail joint as disclosed in the copending case.

Fig. 2 is a view showing the jack as ap plied for disconnection of the said joint.

Fig. 3 is an end elevation, and

Fig. 4 is a fragmental view partially in section showing the details of construction.

As fully described in the copending case, the rail joint is made up of rail sections with abutting ends held in position by connectors 5 and 8. The connectors are forced from the position shown in Fig. 1 to the position shown in Fig. 2 with lugs 4 and depressions 9 interlocking, when assembling, and are forced from the position shown in Fig. 2 to that shown in Fig. 1 when disconnecting. As applied in the preferred embodiment, the function of the present invention is to provide a convenient tool to perform the assembling and disconnecting operations as set forth.

The tool is made up of an anchoring member 20 having a slot 21 formed therein which is deep enough to seat on and firmly grip the head of the rail. Pivotally mounted on 20 by means of a pin 22 and guided in slot 23 is an arm or handle 24. Pivoted to handle 24 by means of pin 25 is a locking pawl arm 26 arranged to coact with teeth 27 formed on the upper edge of member 20. Pivoted to member 20 by means of a pin 28 is a fulcrum block 29. A slot 30 formed in 29 is arranged to permit free pivotal movement of block 29 about pin 28, and a pin 30, adapted to fit'through holes 31 formed for registration in block 29 and member 20, is provided to prevent'this piv otal movement of 29. Block 29 is formed tofitagainst connector '5 as shown in Fig. 1, when the tool is in assemblingposition,

and against connector 8 when in disconnecting position. I I

At the lower end of handle 24', lugs 32 are formed in a manner to co-act with teeth 33 formed on hook members 34. At the other end of members 34, projections or lugs 35 are formed.

Guide members 36 are provided for maintaining members 34 in proper relation during the use of the tool.

To assemble the joint, the tool is applied, as shown in Fig. 1, with block 29 resting against connector 5 and with pin 30 in place to prevent pivotal movement of 29. Members 34 are placed with teeth 33 hooked over lugs 32, connector 8 is positioned at an angle as shown in F ig. 1 so that lugs 4 will start into depressions 9 and projections 35 are hooked over the edge of connector8, as shown. A pull is then applied on handle 24 to move it about pin 22 to force connector 8 into the position shown in Fig. 2.

As the lower end of 24 moves to the left in Fig. 1, pawl 26 will move to the right, and

will serve as a lock to assist a single operator in handling the joint. If difliculty is eX- perienced in forcing the parts together the pawl will lock the parts in stressed position andthis will permit the operator to release his hold on handle 24 while he taps on connector 8 to force it into assembled position. After assembly, a supporting tie is preferably placed beneath the joint.

To disconnect a joint, the tie underneath is removed and the tool is then applied as shown in Fig. 2 with pin 30 removed and wit-h lugs 35 inserted in slots 15 of connector 8. By applying a pull to arm 24, connector 8 will bear against block 29 and the claimed as new is:

sired to be secured by Letters Patent and r 1. A tool vcomprising an anchoring memben; a handle. pivoted 110" said anchoring member; a detachable hook member adapted to be engaged and stressedby said handle;
