`J. J. SIMONS, OF EAST ST. LOUIS, ILLINOIS.

Leners Patent No. 85,703, dated Janna/ry' 5, 1869.

-mrPRovn-D PILE-DRIVER.

nl Bohdule referred to in these Letters Patent and making part of the same.

To all whom fit ma/y concern:

Be it known that I, J. J. Simons, of East St.`Louis, in the county of St. Clair, and State of Illinois, have made certain new and useful Improvements in Pile- Drivers; and I do hereby declare that the following is a full and=clear description thereof; reference being had to the accompanying drawings, andto' the letters of reference marked thereon. V

This invention relates more especially to portable pile-drivers, such as are usually sustained ,upon wheels,

and frequently are set upon ordinary wagons; and the nature thereof is in the arrangement of the parts in such wise that the pile-driver frame maybe easily placed in the proper position, (be the same vertical or inclined.) Said nature is further in certain devices for holding and guiding the pile or post in driving, and in certain other detail features, hereinafter fully explained.

Io enable those skilled herein to make and use my invention, I will proce-ed to describe the same more fully, referring to- Figure'l as a side elevation; to

Figure 2 as an end' elevation;

Figure 3 as a plan and section at the line :c y.

Eigure 4 is a detail view, showing the hoisting-drum and its brake.

I support my said pile-driver upon any frame-work,

' which may have ordinary wagon-wheels, as in the application of said machine for driving fence-posts. The lower frame-piece,` A, of the machine is ordinarily connected, by means of a screw, a, at the rear end, on the sub-frame, the said screw being used to elevate or depress the rear end of the frame, as may be' necessary. v To the frame A,I attach the vertical uide-frame pieces B, between which the ram or weig t O slides,

and is operated in the usual manner.

,The inclined braces D connect the upper part of the frame B with the rear end of A, and, in order that the angle-of the ames B and A may be variable, I arrange the\slotted racks d at the ends of the'braces D, engaging with said racks the cog-wheels a, which are on the shaft a, secured to the frame A.

A crank or lever, a3, is used to operate the cogwheels a, and thereby raise or lower the braces D, and thus adjust the angle of the frames B and A.

In order that the frame B may follow the motion imparted through the braces D, as aforesaid, I connect said frame B, by pivot-bolts b, with the forward 'end of the frame A.

The forward ends of the frame-pieces A areconnected by a transverse bar, A. This rests-on a subframe, (usually the support of a wagon-box or bed,) E.

The uprights e pass up through slots e in A', and there is suiicient -room for lateral movement of the frame A.

In order to adjust the front end of the frame A as to height, I arrange t crews Fin the bar A', actin similarly to the screw a at the rear end of A.

' The screws F, by impinging on the upper surface of E, will secure the entire frame-work against lateral vibration.

The pile or post G is placed, in the ordinary manner, between the standards B.

In order to sustain and guide the pile, when propelled into the soil under action of the ram, I arrange the sliding T- shaped clutches H. @These are hinged to the bars h, allowing them to move up, to clutch the p ilenear its upper end. The handles hl being turned forward, the clutch-prongs h2 of said clutches H are driven (by-a mallet) into the body of thel pile, and the said clutches then slide down on the bars h, always holding and guiding the pile.

When the pile is driven, the operator grasps the handles h, and draws back the clutch, it moving in a horizontal circular arc.

The ram C is raised by a rpe, c, attaching to the ordinary' clutch c'.

Said rope c passes downto the drum I on the shaft fi, operated by crank 'i.

In order that the rope. may be lowered quickly, so

that the clutch c' may engage the ram O, (after its' fall,) I use the lever-brake K (which is hinged to the frame B at k) to move the drum I laterally on said shaft i, until the interior mortise' of the drum is released from the square or octagonal shoulder i2 of said shaft, as. indicated in fig. 4. The drum then turns loosely and freely on the round part of said shaft i, andthe clutch c draws down the rope.

To check the motion Aof the drum, the operator presses down the lever-brace K upon the drum, and thus, by the friction, checks its motion.

Having thus -fully described my invention,

1. The frame A, its screws a and F, the transverse bar A', and sub-frame E, standardA e, and slots e', substantially as set forth.

2. The sliding clutches H, and their bars h, when acting substantially as and for the purposes set forth.

In testimony of which invention, I hereunto set my hand, in presence of- J. J. SIMONS.
