WEDGE-DRIVER.

SPECIFICATION formingpart of Letters Patent No. 256,359, dated April 11, 1882.

. Application filed December- 15, 1881. (No model.) i

' To all whom it may concern Y Be it known that I, OTTO MossBERGER, of

Guttenberg,in the county of Hudson and State of New Jersey, have invented anew and Improved Wedge-Driver,'of which the following is a full, clear, and exact description. 1

The object of my invention is to provide a new and improved apparatus for driving wedges, especially adapted to be operated by horsepower or other draft-animals. i

The invention consistsin a vertically-reciprocating hammer, connected by adjustable connec'ting-rods and cranks with a collar loosely mounted 'on a shaft provided with a fixed cogwheel, and rotated by means of an intermediate train of gear-wheels from a circular rack mounted on a wagon-frame and adapted to be rotated by draft-animals. The loose collar is provided with an automatically-operating clutch device, which engages it with the fixed cog-wheel on the rotating shaft, whereby the hammer will be raised and then released'automatically when it has reached its greatest height.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of my improved wedge-driver. Fig. 2 is a cross-sectional elevation of the same on the line 00 ac, Fig.1. Fig. 3 is a perspective view of a'drill-driving attachment adapted to be attached to the bottom of the guides of the hammer or sliding block. Fig. 4 is a partial'longitudinal sectional elevation of the rear end of the wedge-driver, showing the arrangement of the gearing. Fig. 5

is a perspective view of the loose collar, pivoted pawl, and ratchet-wheel. Fig. 6 is a detail view, showing the connection between the loose collar and the hammer.

Thesquare or oblong base-frameAis mounted on four or more wheels,B, and carries a circular frame, 0, on which a circular rack, D, fits loosely in such a manner that the rack D can be rotated on the circular frame 0. This circular rack D engages with a cog-wheel, E, rigidly mounted on a horizontal shaft, F, journaled in the middle of its upright frame G, resting on the base-frame A. This cog-wheel E also engages with a pinion, H, rigidly mounted end a cog-wheeler ratchet-wheel, M, or wheel On the end with recesses in the periphery. of this shaft L, and adjoining the cog-wheel or ratchet-wheel M, a collar, N, is loosely mounted. Arod or arm, 0, extends from this loose collar,

N, and passes through acollar,P, looselymounted on the end of a connecting-bar, Q, provided at its outer end with a flange, It, provided with an aperture, through which a rod, S, passes, at-

tached to a collar, T, loosely mounted on a pivot y at the upper or outer end of acrank-bar, o, pivoted to a hammer or block, V, adapted to slide verticallyin guides W, fitting in grooves in the hammer.

The collar P on the end of the connectingbar Q can be adjusted and locked on the rod or arm 0, extending from the collar N, by means of a set-screw, a, and the flange R of the connecting-bar Q can be adjusted and locked in any desired position on the rod S,

attached to the collar T on the crank-bar o, by means of a set-screw, b. A book or catch, Y, is pivoted on the collar N in such a manner that it can pass in between or engage with the teeth of the cog-wheel or ratchet-wheel M.

This book must be attached to the collar Nin such a manner that it will be at top or highest point of the collar N when the hammer or blook'V is in its lowest position.

A frame, 0, fitting on the lower ends of the 1 guides W, and secured thereto by the setscrews a, is provided with a vertical central aperture, adapted to receive and hold loosely a drill, d, which is to be raised when it isdesiredto drill a hole.

The frame A is provided with a socket for receiving the rear end of a draft-pole, and the rack D is providedwith a socket, f, for receiving a downwardly-curved coupling-bar,g, provided at its lower end with a fork, h, for receiviu g the rear end of a draftpole or a whiffletree.

The operation is as follows: As this machine is especially adapted for driving wedges into stumps for the purpose of splitting these stumps, it will be described as driving a wedge into a stump; but it can be used to drive drills or to drive posts or piles, the frame A being raised if the machine is to be used for the latter purpose. By means of horses the frame is drawn to and over the stump until the hammer-guides W are over the stump X. The wedge Z is placed on the stump, and the horses are coupled to the circular rack D by means of the coupling-barg. If the horses are driven around the stump-that is, around the baseframe Athe rack D will rotate the wheel E, which in turn rotates the pinion H, the shaft I, and the wheel J, which rotates the pinion K, the shaft L, and the cog-wheel orratchet-wheel M. The hook Y on the loose collarN passes in between the teeth of the wheel M, and thus causes the collar N to rotate with the wheel M, whereby the hammer or block V will be raised, as the hammer V and the collar N are connected by means of the rod 0, the connecting-bar Q, the rod S, and the crank-bar a. When the hammer reaches its highestposition the cog-wheel M and the collarN will have made a half-revolution and the hook Y will be at the lowest point of the collar N, and by its own weight this hook drops out from between the teeth of the wheel M,thus disengaging the collar N from the wheel M and permitting the hammer or block to drop upon the wedge Z; but by this downward movement of the hammer the collarN will be rotated completely, or it will be rotated back again in the reverse direction of its movement while the hammer was being raised, and the hook Y will be atthe top of the collar N again, and will drop in between or engage with the teeth of the wheel M, and the collar N will again be rotated with the wheel M, and the hammer will be raised and will drop again when the wheel M has made halt a revolution, and so on. In this manner the blows of the hammer will follow each other in rapid succession, and none of the motion of the rack D or the power of the draftanimals is lost. In case a rock is found below the stump a hole is drilled into it by means of the hanimer and the drill 01 held in the frame 0,

. attached to the bottom of the guides W. As

The number of gear-wheels and pinions in the train of wheels interposed between the hammer and the circular rack may be increased or decreased, as may be desired.

A rope may be attached to the shaft I and used to raise the parts of the split stump, for if this rope is attached to the shaft I it will be wound on this shaft when the machine is operated. The hammer parts are to be disconnected while raising the parts of the stump.

Having thus described my invention,Iclaim as new and desire to secure by Letters Patent 1. In a wedge-driver, the combination, with a shaft rotated by means ofa circular rack and a train of gear-wheels, of a cog-wheel mounted rigidly on this shaft, a collar mounted loosely on thisshaft,andconnectedbyconnecting'rods and crank-bars with a vertically-reciprocating hammer, and ot' a clutch device for engaging the loose collar automatically with the cogwheel on the shaft, substantially as herein shown and described, and for the purpose set forth.

2. In a wedge-driver, the combination, with therevolvingshaftL,ofthecog-wheelM,mounted thereon, the loose collar N, the hook Y, the vertically-rcci procatin g ham merV, and devices for connecting the collar N and the hammer V, substantially as herein shown and describcd, and for the purpose set forth.

3. Ina wedge-driver, the combination, with the revolving shaft L, of the fixed cog-wheel M, the loose collar N, the hook Y, the rod 0, the connecting-bar Q,provided at one end with aloose collar, P, and at the other end with an apertured flange, t, the rod S,the crank-bar o, pivoted to the hammer V, and provided with a loose collar, '1, substantially as herein shown and described, and for the purpose set forth.

4. In a wedge-driver, the combination, with a rotating shaft, of a fixed cog-wheel and a loose collar thereon, an adj ustablc connectingbar for connecting the loose collar and the pivoted crank-bar of a reciprocating hammer, and a clutch device for automatically connecting the fixed cog-wheel and loose collar for the purpose of raising the hammer, substantially as herein shown and described.

5. The combination,with thehainmer guides W and the reciprocating hammer V, of the frame 0, fitting on the lowerends of the hammer-guides and adapted to hold a dril d, substantially as herein shown and described.
