PILE-DRIVER..

SPECIFICATION forming part of Letters Patent No. 759,534, dated May 10, 1904.

l l Application filed August 25, 1908. Serial No. 170,742. (No model.)

To all whom it warty concern.-

Be it known that I, EDWARD S..LI 1Ao1-I, a citizen of the United States, residing at Cooper Hill, in the county of Osage and State of Missouri, have invented certain new and useful Improvements in Pile-Drivers, of which the following is a specification.

This invention has for its object to provide a novel construction of pile-driver, the vital feature of the invention being to attain amachine in which the leader-frame may be adjusted so as to drive the posts or piles into the ground at an angle or vertical. l he.derrickframe is also peculiarly mounted, being carried by a pivoted supporting-frame, which is adapted to dispose the derrick-frame in variable positions relative to thebody upon which the smpporting-frame is carried.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and drawings hereto attached. I

While the essential and characteristic features of the invention are susceptible of modification, still the preferred embodiment of the invention illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a machine embodying the invention. Fig. 2 is a top plan view of the pile-driver. Fig. 3 is a front elevation. Fig. 4 is a detail perspective view, parts broken away, showing the peculiar manner of supporting the derrick upon the pivotallym"ounted supporting-frame. Fig. 5 is a sectional view, parts broken away, taken through the adjacent parts shown in Fig. 4.

Corresponding and like parts are referred to in the following description and. indicated. in all the views of the drawings by the same reference characters.

The main supporting-frame 1, which carries the derrick 2, is pivotally mounted, by means of a pivot 8, upon a truck-body 4, by which the machine is inoved from one place to another. The truck-body 4 may be the body of a farm-wagon if the driver is intended for light work or a car-body should the driver be winch,

Y utilized for heavy work, such as driving large piles and the like. The supporting-frame 1 r is thus adapted to be rotated because of its peculiar mounting to thereby dispose the derrick-frame 2 in any desired direction relative to the truck 4. The derrick 2 is of ordinary type, generally speaking, and carries the leaders 5, which are suspended from a cross-bar 6 at the upper portion of the derrick-frame. The hammer 7 is mounted for shdable movement between the leaders 5 and is actuated by the hammer-line 8, which passes around a roller 16, actuated by a pulloyl? and connected by an operating-cable to the machine- Nippers 9, depending from the hammer-linc 8, cooperate with the 11001: 10 of the hammer 7 in the usual manner, being actuated to release the hammer by means of the cams 11, provided. upon the inner faces of the leaders. The derrick 2 consists of spaced up rights having their lower ends passed through collars 12, swivelly disposed upon rigid arms l3, projected upwardly from the supportingframe 1. The lower extremities of the said uprights are received in sockets 14, alsodisposed upon the frame 1. The purpose of the peculiar mount of the derrick relative to the frame 1 is to adapt the former to be folded down upon the frame 1 when the machine is not being used or when the same is being moved from one place to another. Brace-rods 15 are connected to the rear of the frame 1 and the upper portions of the derrick-uprights to brace the derrick structure when in operative position. Leaders 5 are provided with legs 18, slidably mounted in guides upon the lower portion of the said leaders, which are adapted to steady the position of the leader-frame by contact with the ground. Bars 19 are likewise slidably mounted in guides upon the sides of the supporting-frame 1, and these bars are also provided with legs 20, which are adapted to prevent tilting of the supporting-frame 1 in a manner which will be readily comprehended. When the parts of the machine are out of use, supporting-legs 20 and 18 will be moved in the guides in which they are supported in such a position as to lie flat with the other operating parts.

As before mentioned, the leaders 5 are pivotally secured to the derrick 2, and thereby adapted for adjustment so as to drive vertical or at an angle. To fix the adjustment of the said leaders relative to the derrick, toothed bars 21 are pivotally connected to the leaders 5 and are provided with the toothed portions 21*, and these bars cooperate with plates 22, carried by the supporting-frame 1, to fix the adjustment of the leader-frame. To fold the derrick down upon the wagon, the. same is given an upward movement to throw the lower extremities from the sockets 14, and then said derrick is given a pivotal movement to throw the body thereof down upon the truck 4, the bars 15 and 21 being disconnected from the other operating elements to permit of the above. The supporting-frame 1 should of course be disposed in lines of the truck 4 when the parts of the structure are in their folded positions, as above described.

Having thus described the invention, what is claimed as new is- '1. In apile-driver, the combination with a supporting-body, a frame pivotally mounted upon the said body, arms projected upwardly from the frame, pivoted collars carried by the said arms, a derrick disposed upon the frame and comprising uprights having their lower ends received by the pivoted collars of the aforesaid arms whereby the derrick is adapted to fold down upon the supportingfralme, and leaders suspended from the derric I.

2. In a pile-driver, the combination with a supporting-body, a frame pivotally mounted upon the body and provided with upwardlyprojecting arms, collars swivelly secured to the said arms, sockets rigidly applied to the frame adjacent the said collars, a derrick comprising uprights having their lower ends passed through collars aforesaid and received by the sockets for rigidly maintaining the derrick in a working position, and leaders suspended from the derrick and adapted for angular adjustment relative thereto.

3. In a pile-driver, the combination with a supporting-body, a frame pivoted to the said body, arms upwardly projected from the said frame, collars swivelly secured to the said arms, sockets carried by the frame adjacent the said collars, a derrick comprising uprights having their lower ends passed through the said collars and received by the sockets, leaders suspended from the derrick, and legs adjustably mounted relative to the leaders to position same and legs carried by the supporting-frame to prevent tilting thereof.

4:. In a pile-driver, the combination with a supporting-body, a frame pivoted thereto for movement approximately in the plane thereof, a derrick comprising spaced uprights, arms projected upwardly from the frame, collars swivelly mounted upon the said arms, sockets carried by the frame to receive the lower end portions of the derrick-uprights, the latter passing through the collar aforesaid, leaders suspended from the derrick and carrying the hammer, bars pivoted to the leaders aforesaid provided with toothed portions for engagement with the pivoted frame to fix the angular adjustment of the leaders, and supporting-legs carried by the leaders and the pivoted frame for rigidly maintaining the same in an operative position.

In testimony whereof I afliX my signature in presence of two witnesses.
