IMPROVEMENT IN PILE AND POST-DRIVERS. y

' The Schedule referred te inlthese Letters Patent and making part of the same.

I, N OAH HAVERMALE, of Canton, in the county of Fulton and State of Illinois, have invented certain Improvements in Pile and Post-Dri-vers, of whiclrth'e following is a. specification. v

The natnreoi` my invention consists in providing a. suitableirame-work thatcan be loaded and hauled upon an ordinary wagon.

To the frontend of the frame two guide-posts are to any angle, and properly braced when set up.

To the cap is attached the main line, which passes downward, and' suspends a m`ovable pulley, to which is attached the shipping-hook, which raises and drops the hammer. The line passes from the movable pnlley over one fixed to the cap, and thence to a windlass or other power. Y The shipping-hook is so constrncted'thai-,by means 'oifa cord, the hammer is let fall from any desired ele- The construction of the framefwork, the connection of the hammer, and the ease lwith which the weight is discharged at any height, make this machine peculiarly adapted to the driving `of piles for highwaybridges `:or coffer-dams, or .the posts of an ordinary post-and-board-fence.

Figure 1 is aperspectivc elevation` of a pile and l post-driver. Figure 2 is a side elevation of the shipping-hook.

VFigure 3 is an edge elevation of the draft-bar of the yshipping-hook. Y

Figure. 4 is avertical section, showing compound guide-arms'.

' Figure 5 is a front elevation of hammer, guide-arms, and-the foot of 'one post. r

i General Description.

fill mortises in sills L, to which they are connected by suitable hinges, V.

Of any required weight I make the hammer H, cast with mortises to receive the wooden guide-arms i) b, which have a slot i-n each end to work up and down On one side of' the hammer these arms have, on their front edges, a movable section, a, turning vertically npona bolt, the outer end of the section forming projection cast upon the hammer and abutton, c, upon the upper side of arm. (See igs. 4 and 5.)

Of 'suitable size and metal I makethe draft-bar A, as shown in figs. 2 and- 3, having the vlever-hook I pinned'within the lower-endof the sides, and connected to the jointed lever I, that is pinned between the sides of the draft-bar above the joint, and then bent-upward, and terminating in an eye, in which is fastened the cord K. The joint of the lever I sets slightly toward the bar A, and the weight rests upon the Aset-screw or pin J, that is secured to a plate riveted between the sides of the bar.

When the machine is to be used for driving piles for a bridge, proper false work is made, about the height thepiles are to be when driven. Then the frame of the driver is removed from :the wagon, set on the false work, and properly leveled. If necessary, a sub-sill is placed nn'der the -front end, extending far enough on either side to allowbracing from the ends of the sub-sill to the rings Z Z." The cap Y is placed upon its tenons, and the tenons of the braces X X are entered. The guide-posts W W are then raised to a right angle with the'sills by means of the braces It R, their upper ends being bolted to posts. Then their lower ends are to be bolted to S S of the windlassframe. Placethe hookof the movable pulley M into G, the eye of the hammer-,fand draw it by the windlass to the platform U, and put in theshipping-hook. When theguide-arms b b are adjusted, the sections a a being raised Yso as to open the slotsl raise the hammer,ix the arms in their places, close the slots, and fasten the sections by putting the inner lends down behind the projections on hammer until they touch the bottom shoulder ot' projections, and secure themthere by turning the buttons c c. The pile being ready, raise the hammer, by means of the windlass, to any desired height. Then pull on the cord K until joint in I is straightened, and the hammer discharged. If 'the height from which the blow is to be delivered is determined, tie the cord K at the proper length to the frame, and the hammer will be dischargedf If it is desirable to drive the piles at any inclination, as for a entier-dam, shorten the coupling 0f the braces R R at their lower ends, as desired, bringing the top of W inward, and proceed as before stated.

When the machine is to be used for driving fenceposts, it is made of suitable size, remains upon the wagon, which is driven on the desired line of fence,

posts W,guidebars D, braces X, cap Y, braces R and S, posts T, windlass P, rope O, land pulleys M and N,

when combined and arranged in the manner shownY and described, and for the purpose set forth.

2. The hammer H, guide-arms b, sections a, buttons c, guide-bars D, and posts W, when combined and arranged in the manner shown and described, and for the purpose set; forth.
