JOSEPH XV. PUTNAM, OF NEV ORLEANS, LOUISIANA.

PILE-DRIVER.

SPECIFICATION forming part of Letters Patent No. 312,582, dated February 17, 1885.

Application tiled April 29.71854. (No model.)

To all whom it may concern:

Be it known that I, J osErH W. PUTNAM, of the city of New Orleans, parish of Orleans, and State of Louisiana, have invented a new and useful Pile-Driver; and I do hereby declare the following to be a full, clear, and exact description of the same. f

My invention relates, principally, to an improvement in the class of pile-drivers which are used for the construction and maintenance of ways for railroads, being forthe purpose mounted on a truck or platform car, in such manner as to allow it to swing in the arc of a circle, or revolve completely around, if desired; and the objects of my invention are, first, to provide an improved means by which vertical or oblique piles may be driven in any desired position; second, to afford improved means or facilities by .which the leaders may be lowered on a flat or platform car, so that the apparatus can pass through bridges or tunnels. Oblique piles are very necessary in various placesviz., as batter or brace piles in pile trestlework, to give a wide'base and render the structure rigid and steady and to concentrate the piles directly under the stringers or bear ing-points, thereby evenly distributing the load on the piles inclining against the ends of embankments so that the piles may not be overloaded with weight of earth; also, for giving a broad base to pivot-piers for drawbridges, Src.

I attain the objects enumerated aboye by the mechanism described in the following specication and illustrated by the accompanying drawings, forming part of this description, in which-- Figurel is a side elevation of the pile-driver as erected on a platform-car for service on the railroad. Fig. 2 is an end elevation. Fig. 3 is a plan of the driver. Fig. 4 is an inverted plan showing arrangement of ropes for operating the turn-table. Fig. 5 is an enlarged plan view of the sliding block, showing the position and arrangements of ropes for operating same; Fig. 6, elevation of sliding block, and Fig. 7 is afront view of the sliding block. Figs. 8, 9, and 10 are respectively a front and side elevation and plan of the universal 5o joint'conneoting the leaders to the frame and braces.

Similar letters of reference refer to like parts throughout the several views.

The platform`A of t-he pile-driver proper is pivoted centrally and placed horizontally, as shown in Fig. 1, on a truck or platform car, B, adapted to run on a railroad. The platform A is adjusted or swung on its pivot by the ropes C, over the sheaves a a' and b b c c. By this arrangement of ropes and sheaves the platform may be easily swung so as to drive a pile between the rails or at a great distance on either side. The leaders or hammer-guides D are trussed to render them light and strong, and are suspended from the top of the triangular iron frame E by a double joint, J, al lowing them to swing sidewise across the car and fore and aft. A

The triangular iron frame E is secured to the platform A by hinges h h', allowing it to move forward and back at the top, and is regulated by the elliptic brace F, connected at f with the triangular iron frame and at g with the movable block G. The ends of this block G are tenoned into long grooves made in the bedtimbers H. This block Gis moved backward and forward by the screw I, which passes through anut placed in the center of the block, and is operated by the bevel-gear c from the engine-shaft Ic, and this gear is thrown in and out by means of a clutch. (Not shown.) By this means the leaders can be placed and maintained at any desired angle fore or aft. The foot of the leaders D are attached to a sliding block, L, at the front end of the platform A by a long vertical stirrup, m, passing through an eyebolt, a. The sliding block L is secured to the platform A by a T-beam, O, inverted, the head of which slides in a groove in the upper side of a curved bed-timber, P. The

iron, and has a line of holes, W, in same for receiving a pin which is placed at back of sliding block L to maintain it in position. The sliding block L is moved in the groove in top of this curved bed-timber P is faced with top of curved bed-timber P, and across the end of the platform A, carrying with it the foot of the leaders D by the ropes i i', each of which passes around two sheaves, ss and r r', and is then taken to the engine-winch. The sliding block L, carrying the foot of leaders D,

is thus moved in either direction to any de- IOO - Y, placed in the upper end of the triangular iron frame E, and is secured by a nut, Q, thus forminga double joint, by means of which the leaders D may be placed in such position as to drive a pile obliquely in any direction to a vertical line.

In the top of the triangular iron frame E is placed two small sheaves, tt', Figs. 8, 9, and 10, to guide the hammer line and to keep it in position, so that at whatever angle the 'leaders D may be placed the hammer-line will be maintained in position t0 pass over the sheaves p p and K to the drum Z. 'A

When it is desired to lower the leaders so as to p ass through a bridge or tunnel, the screw I is set in motion and top of triangular iron frame E pushed forward until the lower ends of leaders rest on theground. Apair of blocks and line are then attached to the triangular frame E and the leaders D, and the nut Q Qn end of shaft V is removed, when the leaders may` easily be lowered to a iiat car, and the triangular iron frame E also lowered until it will pass through the bridge or tunnel. The said tlat car is placed on the track in front of the car 13,011 which the pile-driver is mounted, and the object of the removal of nut Q is to entirely detach the leaders from connection with the other portion of the pile-driver, that being obviously a necessary preliminary to lowering them onto the car in advance of car B. To replace the leaders in working order, the blocks and lines are attached as when lowering the leaders, and the lines run to the en.- gine-winch, when they may be easily raised to their position. The pileAdriver may also be built on the deck of a barge, or the platform may be so arranged as to be transferred from the car to a barge.

I do not claim, broadly, the pivot'ed platform A, the trussed leaders D, the elliptic brace F, and the movable block G and screw I, as they are described and claimed in Patents Nos. 229,461 and 229,462, dated June 29, 1880.

Vhat I claim as new, and desire to secure by Letters Patent, isl. In a pile-driver so constructed and arranged that a pile may be readily driven vertical or oblique in any direction to a vertical pile, the combination of the pivoted platform A with the hingedleaders D, connectedby the double joint with the triangular iron frame E, substantially as set forth.

2. In a pile-driver, the combination of the 'adjusting-brace F and movable block G and screw I with the triangular iron frame E,sup porting the leaders D'by the double-joint arrangement J, all substantially as described.

3. In a pile-driver, the combination of the hinged leaders D with the sliding block L, and the lines v3 z, and sheaves 8 s and r o, and the eyebolts n n', and long stirrups m m', all substantially asset forth, and for the purpose specicd.

4. In a pile-driver, the combination of the platform A and curved deck-beam I), provided with iron plates having holes IV, with the sliding block L, provided with T-iron O, and lines and sheaves, all substantially as set forth.

5. In a piledriver, the combination of the J. IV. PUTNAM.
