JOHN G. STIGER-S, OF GLEN HOPE, ASSIGNOR OF ONE-HALF TO SAMUEL HEGARTY, OF HEGARTYS GROSS ROADS, PENNSYLVANIA.
POST-DRIVER.
SPECIFICATION forming part of Letters Patent No. 331,740, dated December 1, 1885.
Application filed May 6, 1885. Serial No. 164,592. (No model.)
To all whom it may concern.-
Be it known that I, J oHiv G. STIGERs, a citizen of the United States, residing at Glen Hope, in the county of Olearfield and State of Pennsylvania, have invented certain new and useful Improvements in Post-Drivers; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.
My invention has reference to machines for driving posts or stakes into the ground; and it consists in the improvements hereinafter set forth, whereby a simple and efficient machine for performing the character of work stated is produced, and the general arrangement such as to require but comparatively little labor on the part of the operator or attendant.
In the accompanying drawings,forining part of this specification, Figure 1 is afront view of a structure embodying my improvements. Fig. 2 is a central vertical section of the same, and Fig. 3 is a detail plan view of the base employed for the structure.
The supporting-frame of the structure consists of a base, A, side standards, A, supported on said base by means of tenons, and also provided with tenons at their upper ends to receive and support a top piece, A. These parts of the frame are braced and re-enforced relative to each other by means of vertical rods B, the heads of which are located in the base A, while the upper threaded ends pass through the top piece to receive nuts a therefor. The inner side of each standard A is provided for a major portion of its length with a vertical rib, b, which terminates within a short distance of the bottom to form a stop or shoulder, a.
B refers to a horizontal block which is locat-ed transversely between the standards A, and has its ends grooved vertically to engage with the ribs 2'). The block B is provided centrally on its under side with a dovetailed recess, in which fits a corresponding dovetailed portion of a weight, 0, adapted for introduction into said recess. Bolts attached to said weight pass through said bar 13 and are secured by clamp-nuts.
f refers to a loop which is secured to the bar B or to the weight itself, and projects up above the bar 13, for engagement with the liftinghook. A bar, D, located between the standards A, above the block B also has grooved ends, which engage with the ribs 1). A vertical lever, E, is centrally pivoted on said bar D, and carries at its lower end a hook, g. The upper end of said lever is provided with a loop, h, and it will be observed that it is bent to one side in order that it may be laterally deflected, as hereinafter described, to disengage the weight. A pulley, F, is journaled in the bar D, and is adapted to have a rope or cable, t, passed around the same. One end of said rope or cable is fastened to the hooky of a depending block, J, which is pivotally attached to the top piece, A. The said rope or cable 2, after passing around the pulley F, as described, then passes around a sheave, H, journaled in the top piece, A, and finally extends down to be accessible to the operator. The front face of the base A is cut away at its center to form a depression for the reception and guidance of the post or stake to be driven. The frame is supported in proper position for work by the inclined leg N. This leg is attached to the center of the top bar, A, of the frame in such a manner that it can be moved in any direction either by means of the loop 12. on the end of the leg and the swivel eye a, attached to the pivot-pin of the sheave H, or in any other well-known way.
In practice, the machine having been placed in position with the post to be driven beneath the hammer and resting in the guide-groove of the base-block, and the parts being in the position shown in Fig. 1, the operator pulls on the rope or cable 1', thereby causing the lever E to assume a vertical position, and thus permitting the hook at the lower end of the said lever to engage with the loop F, attached to the block B. Further traction on the said rope or cable vertically raises the bar 1), and also the attached block and weight, until the upper end of the lever E strikes the block J, thereby throwing the lever E to one side, and causing its hook to become disengaged from the loop f of the block B", thus permitting the IOO block 13 to descend by gravity, and the weight strikes with great force the post or picket. The bar D is then lowered, and on tightening the rope after it strikes the weight-bar B the hook g automatically engages with the loop f, as before.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is- I 1. The combination, in a machine for driving fence posts or pickets, of a supportingframe, a base recessed as described, a block having a dovetailed recess, a weight having a dovetailed portion designed to enter said dove- "tailed recess, a bar having a lever carrying a hook to engage said block, means for elevating said bar, and a block for tripping said lever to release the hook thereof from the block, substantially as set forth.
2. The combination, in a machine for driving fence posts or pickets, of a supporting- Witnesses:
