POST-DRIVER.

SPECIFICATION forming part of Letters Patent No. 304,953, dated September 9, 1884. 4

Applicationitiled May 19, 1884. (No model.) Y i To all whom, it may concern:

Be it known that I, WHARTON B. PHILBERT, a citizen of the United States, and a resident of Linneus, in the county of Linn and State of Missouri, have invented certain new and useful Improvements in Portable Fence-Post Drivers 5 -and l do hereby declare that the following is afull, clear, and exact description ofthe in vention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure l is a perspective view of my improved fencepost driver. Fig. 2 is avertical section of the same. Fig. 3 is a horizontal section; and Figs. et and 5 are perspective de tail views of the sledge and its bearings and of the springs drawing it back.

Similar letters of reference indicate corresponding parts in all the gures.

My invent-ion has relation to fencepost drivers; and it consists in the improved construetion and combination of parts of the same, as

hereinafter more fully described and claimed.

, In the accompanying drawings, the letter A indicates arectangular upright frame, mounted upon a wheeled or sliding platform, B, and forming rectangular ways, C, in its corners, in which the inner corners of the corner-posts D of a rectangular sliding frame, E, slide. The upper ends of the corner-posts of the upright frame are provided with pulleys F, over Which pass ropes or chains G, attached at their lower ends to the lower end of the sliding frame at its four corners, and attached at their upper ends to the ends of a windlass, H, journaled transversely in bearings I, formed upon the upper1 edges of two of the sides of the upright frame, and having a circumferential series of perforations, J, at one end, which are engaged by the outer downwardly-bent end of a hook, K, pivotcd upon the side of the upright frame. One side of the sliding frame has two vertical posts, L L, which form L-shaped recesses, M, at their middle upon their inner sides, the upper horizontal portions of which recesses open in the outwardly-facing sides ofthe posts, while the lower ends of their vertical portions form bearings for the trunnionsvN of a roller,

O, in which the inner'end of the handle of the' sledge P is secured, the sledge projecting out at right angles to the roller. A treadle, Q, is pivoted at one end upon the lower end of the sliding frame at the foot 0f the vertical posts, and slides with its outer portion in a guide-bail, It, upon the side of the frame, and a rope or chain, S, is secured to near the outer end of the treadle, passes around the roller, and is secured to the same, and another rope or chain, T, is secured to the other end of the roller, passes a few turns around the same, and is secured to the upper inwardly-bent end of a spring, U, consisting `of a doubled rod having its lower ends slightly divergent, and secured in the lower cross-bar of the side of the sliding frame opposing tothe slcdge. The upper portion of this spring bears against the outer side of a transverse spring-bar, V, secured transversely upon the side of the sliding frame opposite to the sledge, serving to add springiness to the doubled spring.

It will now be seen that the platform, with the driver-frames, may be rolled to the posthole, the post inserted, when, by depressing the treadle, the Sledge may be brought down upon the top of .the post, whenthe springs will again raise the Sledge, and the sliding frame may be lowered by means of the windlass,and be held in"its adjusted position by means of the hook engaging the perforations in the end of the windlass as the post is driven into the ground.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United Statesl. The combination ol" an upright rectangular frame provided with pulleys at its upper corners and mounted upon wheels or runners, a rectangular frame sliding upon the upright frame, asledgc pivotedupon the sliding frame and having means for operating it, a windlass j ournaled in the upper end of the upright frame and having means for stopping it, and ropes secured to the windlass passing over the pulleys at the upper corners of the rectangular frame, and secured to the lower end of theV sliding frame at its corners, as and for the purpose shown and set forth.

The combination of the upright rectangu- IOO lar frame mounted upon Wheels or runners, forming rectangular ways at its Corners, und forming bearings at its upper end, the reota'n4 guiar sliding frame having the vertical posts in one side7 forming L-shaped bearings, the pulleys journaied in the upper corners of the upright fra-me7 the Windiuss journztied in the bearings upon the upper end of the rectangular frame and having the perforutions around one end, the pivoted hook, the rope secured to the Windlass und to the Corners of the sliding frame1 the roller und sledge pivoted in the L-shaped hearings, the treftdle7 the rope so
