UNITED STATES PATENT OFFICE DANIEL C. ARMSTRONG AND WILLIAM I. FITZGERALD, O1 PRINCESS ANNE, MARYLAND.

COMBINED SPIKE-EXTRACTOR AND RAIL-LIFTER.

Application filed January 22, 1908.

To all whom it may concern:

Be it known that we, DANIEL C. ARM- STRONG and WILLIAM P. FITZGERALD, citizens of the United States, residing at Princess Anne, in the county of Somerset, State of Maryland, have invented a new and useful Combined Spike-Extractor and Rail- Lifter, of which the following is a specification.

This invention relates to a combined spike extractor and rail lifter.

The usual practice in effecting repairs of railway rails is to employ an extractor for removing the spikes, and a jack for lifting the rails and holding them elevated while the new cross tie is being positioned, or the road bed tamped up to secure the proper level. The objection to this procedure is that it requires two separate implements to effect the desired repairs.

It is the object of the present invention to provide an implement which shall combine, in a ready and practical manner, a spike extractor and a rail lifter, the parts of the implement being so constructed and arranged that one shall not interfere with the other in use, and, further, in which the rail lifting portion of the implement shall be automatic in its operation in looking the rail in elevated position, and similarly operative in unlocking when the rail is to be lowered to its proper bed.

' With the above and other objects in view, as will appear as the nature of the invention is better understood, the same consists in the novel construction and combination of parts, of a combined spike extractor and rail lifter, as will be hereinafter fully described and claimed.

In the accompanying drawings forming a part of this specification, and in which like characters of reference indicate corresponding parts, Figure 1 is a vertical longitudinal sectional view taken through the implement. Fig. 2 is a similar view, certain of the parts being broken away. Fig. 3 is a perspective view of the implement.

The implement com rises a hollow rectangular base 1, prefera ly of metal, and cast in one piece, or made in sections suitably assembled. Extending upward from the base are two standards 3 between which is pivoted a lever 4 having one end formed into a claw 5 of the type usually employed in withdrawing railwa spikes. The points of the claw, when the atter is in position to engage the Specification of Letters Patent.

head of the spike, is sufficiently spaced from the front wall 6 of the base to insure easy positioning of the claw under the head of the spike, thereby to insure the proper coaction between the parts, and to cause a sufficient straddling of the head of the spike to guard against any danger of slippage.

Pivotally connected with the lever at a point adjacent to the standards are two arms 7, each of which carries an inwardly projecting pin or lug 3, the two being in transverse alinement. These pins are adapted to engage with an inclined plate 9 that is rigid with the standard 10 carried by-the rear wall 11 of the base. The forward end of the plate, or that facing the claw, isrounded or beveled at 12, while the rear end is provided with a transverse notch or seat 13 of a size to receive the pins 8. The normal position of the pins relatively to the plate is above the same, and contact between the parts ensues when a rail is to be lifted, the plate serving to guide the pins to the notch or seat in which they will be held by the pressure of the rail uponthe claw.

In using the implement as a claw or extractor, the base is first placed upon the cross tie with the head of the spike appearing through the opening in the base adjacent to the front wall 6, and the claw is then passed around the head of the spike, and upon downward pressure being applied to the lever at its longer end, the spike will be extracted in the usual manner.

Vhen the track is to be lifted, the base and claw are slipped under the base of the rail, and upon the lever being depressed, the rail will be lifted. During this operation, the locking pins 8 slide down the plate 9, and, as soon as they drop over the rear end thereof, will engage with the notch 18, and thereby prevent the claw end of the implei'nent from owering, so that the rail will effectively be held elevated while the necessary re )airs are being made. When the rail is to be lowered, the long end of the lever is slightly depressed, whereupon the locking pins will drop out of engagement with the notch 13, and will ride up against the under side of the plate until they come into contact with the rounded or beveled front end of the plate, whereupon they will be switched back to the top of the latter and thus be in position again to operate in the manner above described.

It will be seen from the foregoing description, that while the improvements herein de fined are simple in character, they will be thoroughly eflicient for the purposes designed, and will result in the production of a thoroughly reliable and durable implement capable of performing the double functions described.

We claim 1. An implement of the class described comprising a base, a lever supported thereby, a pair of arms pivotally connected with the lever and provided with inwardly projecting pins, a plate supported in an inclined position by the base and with which the pins are adapted to engage, and means for locking the arms to the plate.

2. An implement of the class described comprising a base, standards carried thereby, a lever pivotally connected with the standards, a pair of arms pivotally connected with the lever and provided with inwardly proj ecting pins, and a plate supported in an inclined position on the base and provided with a notch to engage with the pins to lock the lever against downward movement at its operative end, and with a beveled surface to deflect the pins from the under to the upper side of the plate.

3. An implement of the class described comprising a base, standards carried thereby, a lever pivotally supported by the stand ards and providedwith a claw, a pair of arms pivoted to the lever and provided with inwardly projecting pins, and a plate supported in an inclined position by the base and provided at one end with a notch to be engaged by the pins and at its other end with a beveled portion to deflect the pins from the under side of the plate to the upper side thereof.

In testimony that we claim the foregoing as our own, we have hereto afliXed our signatures in the presence of two witnesses.
