SPECIFICATION forming part bf Letters Patent No. 277,894, dated May 22, 1883.

Application filed April 14, 1883. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM V. FLYNN, a citizen of the United-States, residing at Morristown, in the county of Hamblin and State of Tennessee, have invented certain new and useful Improvementsin a Spike-Puller, Lifting- Jack, andStump-Puller; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention has relation to improvements in a spike-puller, lifting-jack, and stump-puller; and it consists in the constr ction, combination, and arrangement of the several parts, as will be hereinafter more fully described and claimed.

In the drawings, Figure 1 isa perspective view of my improved jack; and Fig. 2 is a side view of same, illustrating one mode of using the device; and Fig. 3 is a side view of the device in another position.

My device is composed of the base-plated, made preferably circular, the standard a pro-. jected vertically from the central part thereof, the lifting-bar pivoted at the upper end of the standard,'and the hand-lever, connecting-link, and hook, all of which will be described.

. The lifting-bar b is pivoted about midway its ends on the top of the standard a, and its forward arm, 12, is curved down, as shown, and made of a suitable length so-that its liftingpoint b will rest against the front edge of the base-plate when the lifting-bar is turned down against the said plate, as shown in Fig. 2. The lifting-point b is cut so as to form the claw, as shown, when the device is to be used for the purpose of drawing spikes or stumps. The arm b of bar I) is extended in rear of the standard and connected with the hand-lever inthe manner hereinafter described. The handlever c has one end pivoted to the standard a at a point below the bar I), and extends rearward under the arm I) of the bar I), as shown. This lever 0 is provided on its under side with a series of pins, 0, whichform substantiallya rack for the connecting-loop hereinafter described, and also with one or more eyes, 0

A loop, d, is pivotally secured to the outer end of the arm b and passed around the hand-' lever c in position to engage the pins or teeth a, so as to connect the lifting-bar and handlever, and convey to the former the force applied to the latter in the operation of the machine.

In order to hold the liftingpoint of the bar I) up when a wheel or other object has been raised to a desired height, I employ a hook, e, pivoted to the base-piece, at or near the rear edge of the latter, and adapted to engage the eyes 0 of the hand-lever, as shown in Fig. 3.

My device may be used as a lifting-jack or 6 a stump-puller, or for the purpose of extracting spikes in repairing railroads, bridges, or other constructions where the same are generally used, in which" case the base-plate may be rested fiat down and the. pointvb be pressed I under the head of the spike, and the latter be drawn by depressing the hand-lever; or the several parts may be arranged, as shown in Fig. 2, with the base-plate tilted, so that the foot may be applied, as shown, and aid in drawing the spike. The device may be used. in a similar manner for drawing stumps or posts which extend only to or slightly above the surface of the ground. I

The base-plate is preferably circular in form, So and thus presents a round or curved front edge, which permits the rocking of the machine from side to side when tilted, which motion aids in extracting spikes.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-- 1. The spike-puller or lifting-jack, substantially as described and shown, consisting of the base-plate, the standard projected verti- 9o cally therefrom, the lifting-bar pivoted on the standard and constructed so that its liftingpoint will turn down against the edge of the base-plate, and the hand-lever pivoted to the standard below the lifting-bar and connected 5 therewith in suitable manner, substantially as set forth. a
