POST-DRIVING MACHINE.

SPECIFICATION forming part of Letters Patent No. 286,816, dated October 16, 1883.

Applieation filed May 16, less. (No model.)

into the Earth, of which the following is a specification. l

My invention relates to improvements made by me ina machine known asa pile-driver, so as to adapt it to the use and purpose of driving and setting fence-posts in the earth. I attain this object by mechanism `illustrated in the accompanying drawings, in which* Figure l is a perspective view` of the entire machine. Fig. 2 represents the clamping arrangements for securing the post in position. Fig. 3 represents the grappling-hook for lifting the driving-weight and the part connect ed therewith. Fig. 4 is a'vie'w in detail of the 'tongue and its attachments.

Similar letters refer to similar parts through out the several views. v

rlhe upright frame is an ordinary pile-driving frame, with its guiding-cleats and crossbars, the frame resting upon a base or substructure, which consists of a sled of two wide board runners, with cross-bars combining and holding the runners together, andl upon these rest the other parts o f the machinery, as hereinafter explained. The upright frame is attached to a movable adjustable bolster, J, by two cross-beams at right angles to the bolster and at equal distances from the ends thereof. Across the forward end of these cross-beams is bolted a cap or cross-piece parallel with the bolster, underneath which piece and between said cross-beams, and fastened thereto, is a beam, F, extending at right angles to and forward of said bolster J, toward front end of sled. On the under side of this beam F, near the rear end thereof, a lever, E, vertical to the under surface thereof and extending vertically downward, properly braced, works atits lower end in a slot in the metal plate 0,- fastened to the upper surface and innerl edge of the clamping-bar A, by which lever E the clampingbars A B are moved to the right or left as the top part of the machine, by means of the adjustable bolster J, is inovedto the left or right, so as to hold and maintain the post to be driven of the sled and under the bolster K and the middle upper cross-bar of thesled, being kept in position by two cleats or guides, C C, attached at right angles to the under surface of the clamp-bar A, so that their outer edges work between and against the edges of said lower cross-bars of the sled. The clamp-bar B works 'on a pivot at the front end, and is kept pressed firmly in position against the post to be driven by the spring D pressing the post against the clamp-bar A. The bars A B are connected at the front end by a cross-beam, in which is the pivot of B and the front end of the spring D. Both A and B move at the same time and to the same extent by the action of the lever E. The front ends of the bars A and-B work in a slot between the upper and lower middle cross-bars of the sled.

Attached to the frame-work upon which the derrick stands arethe cross-beams on thebolster J On therighthand is a stationary clamp-bar, G, and attached to the beam F, about-its center, by a pivot is a movable bar, H, which is held in position and pressing toward G by the spring D. These two bars hold in position and safely clamp the top of the post, while the bars AB,

above described, hold in position and clamp.

the lower part of -the post to be driven. The bar A and the stationary bar G serve as a guide for the face edge of the post and keep the same in line while being driven into the earth. The post, being firmly held at the upper and lower ends, and both the upper. and lower clamps being y adjustable, as herein shown, may be set at any angle or pcrpendicularly upon any inclined surface. The inner edges of the rear ends of the bars A B G H are cut at such a bevel that the post can be readily slipped into position from behind, and rounded beveled notches in the edges of the bars B H clasp and hold the post against the bars A G, yet not so tightly as to interfere with the driving the post downward into the ground. The bolster K extends across the sled near the rear end, and the ends ofthe bolster are formed into journals working in theboxes on top of the runners, which permits the bolster to turn forward or IOO backward. This bolster K is connected with the upper bolster, J, by the adjustable hingeroller joint L, and the two holsters being thus j connected, the center of the lower bolster being some inches higher than the ends, the upper side being beveled offl toward each end, permits considerable motion to the bolster J up and down upon said joint as a pivot.

On each side of the bolster K, at each end thereof, are bolted upright standards M M', with slots therein, opposite and facing each other. Between these upright slotted standards the vends of the bolster J work. Through these slots and the ends of said bolster a rod with head on one end and screw on the other passes, whilea nut with tail or handle screwed upon the screw end of the rod clamps the bolster firmly in any position desired between the standards.

N N represent the rods above described, and shown in the drawings. At one or both ends ofthe upper side of the bolster are small spirit-levels R It', by which a horizontal position can be readily determined. On the beam F is also a s )irit-level R inserted in the upper side for the same purpose.

Attached by a pivot to the front edge, at the center of the front cross-bar of the sled, is a slotted standard, P.

In the end of the beam Fis a rod with setscrew working in the slot of the standard I?, by which the end of F may be raised or lowered and secured in position, bringing the top ofthe derriek and other parts ofthe machine into plumb forward or backward. y

The motion and adjustments effected and allowed by the standards IWI, M, and I, enable us 4to place the machine -in a vertical position upon all kinds of inclined surfaces, and also to set and drive posts at dierent angles or perpendicularly, as may be desired, and make the machine completely adjustable in all di'- rections.

In order to further adjust the machine in rmoving from post to post, the tongue b is attached to the front part of the sled by sliding through and into staples on the under side of the front cross-bar and the lower middle crossbar of the sled, and is secured in position by two braces, g g,hooking into staples in the front cross-bar ofthe sled, and into staples on each side of the tongue. Two other staples, a few inches in the rear of those in the tongue, above described, enable the tongue to be pulled forward out of the hinder staple, the braces being placed in the rear staples of the tongue, whereby it (the tongue) is readily converted from an immovable to a movable or limber tongue.

krThe hammer or driving-weight X, for driving posts into the earth, may be of any size and heaviness desired, with guide grooves upon the sides working as in ordinary piledrivers. The lifting bar or bail of the weight X is arod, WV, extending across the top of the weight, covered with a tube or sheath, which rolls upon the rod YV as its axis. The grappling-hook S is guided under the bail XV by the guide V, and the sheath thereon,when the hook is tilted and disengaged, rolls off the hook easily and without much friction. A spring, T, fastened to the guide-bar to which the grappling-hook is attached, presses forward upon the lower end of the grappling hook S and forces it under the bail NV. The arm U, in operating the machine, presses against the plate at top of the derrick, and throws the hook S backward and discngages it from the bail XV, and allows the weight X to fall upon the top ofthe post to be driven, and forces it into the ground. The same effect is produced by pulling upon the rope or cord attached to the upper end of the arm U, so that the weight X can be disengaged at any desired height above the post, by which a light or heavy blow can be given at will.

On each side of the derrick-frame, at suit` able height, are resting-blocks Y Y, operated by springs and cords attached thereto, as shown in the drawings at Z Z, by which the weight`X may be held in position at will. Upon raising the weight the resting-blocks are withdrawn from under the weight by force of the springs.

I am aware that prior to my invention pile and post driving machines have been made and used for driving posts into the earth by lifting, disengaging, and letting fall a heavy weight upon the top of the post to be driven, and that devices have been made and used for adjusting same to uneven surfaces, and I recognize the patent to T. XV. Loveless, No. 20,883, issued July 13, 1858, entitled Pile- Driver, 7 and I claimnothing therein contained. I therefore do not claim such a combination, broadly; but

YV hat I do claim as my invention, and desire to secure by Letters Patent, is-' l. The combination, in a post-driving machine, of the movable and adjustable clamping-bars A B and spring D, for the purpose of clamping and holding the lower end ofthe post to be driven in proper position, and the lever E, attached to the under side of the beam F and vertical to the under surface thereof, and extending downward until lower end of said lever is received into the slot in metal plate O, fastened to upper surface of clamping-bar A, the said several parts, the beam F, and the bolster J so arranged and connected, as described in the foregoing speciiication, that the lower end of said lever E, working in said slot, simultaneously moves the clamping-bars A B to the right or left as the top ofthe uprights are moved to left or right by lowering or raising one or the other ends of the bolster J, whereby the post to be driven is adjusted, substantially as and for the purposes set forth.

2. The combination, in a post-driving machine, of the stationary clamp-bar G, the movable bar H, and the spring D, for clamping, ad-
