Application filed July 5, 1390. Serial No. 357,860. No model.)

To all 1 071,012?) it may concern.-

I ie it known that I, JOSEPH P. MERRIAM, a citizen of the United States, residing at Sandusky, in the county of Erie and State of Ohio,

ing and hoisting piles, stakes for fish-nets,

mooring-posts, and the like; and it consists in certain combinations and arrangements of parts, as hereinafter set forth, and particularly pointed out in the claims.

In the drawings, Figure 1 is a perspective view of a fiat boat or gondola equipped with my improved machine. line 2 2, Fig. Fig. 3 is a side elevation, partly in section, on line 3' 3, Fig. 4; and Fig. t is a top plan view.

My machine can be mounted upon any suit able foundation or support, either floating upon the water, as illustrated, or resting upon the land or on a dock or other structure. It is especially designed, however, for the use of fishermen in setting stakes for weirs, traps, and other nets. It may be driven by the engine used to propel the boat or by an independent motor, as desired. The power may be transmitted in any convenient manner, asby a shaft A,extending from the engine to the machine. A bevel-pinion a on said shaft is engaged by a bevelgear 13, secured to a shaft 0, extending transverse of the framework D of the machine. The engine is preferably a reversible one, so that the shaftC can be rotated in either direction at will.

Secured upon the shaft (3 is agear-wheolc, which meshes with a similar gear 6 on a shaft E, parallel with and above the shaft 0. .On this shaft is fastened a face-plate or disk F, and at a little distance from it is a similar face-plate F, the latter being splined upon the shaft, so as to be capable of some axial movement thereon Between these faceplates is a spool G, loosely mounted on the Fig. 2 is a section on shaft, and provided at one end with an annular groove for the reception of a friction band-brake g, controlled by a handle G.

The movable faceplate F is provided with n arrangement for sliding it along the shaft. prefer to use a togglc-jointlever ,onelink E which is pivoted to an abutment (Z, rising from the framework I), the other end being pivotally attached to a loose collar f, seated in a groove in the hub of the face-plate. An earf, projecting from the collar, affords a convenient point of attachment for the toggle,and also serves to keep the collar from rotating with the faceplate, being received in a notch cut'in the upper edge of the bracket or arm (1, fastened to the frame-work D and extending up around or near to the shaft E. A connecting-rod f runs from the joint ofthe toggle to an operatinghandle f When this handle is pulled lJZLCK, the toggle is extended, and the face-plate F is forced against the end of the spool. A continuance of the movement slides the spool against the fixed face-plate F, and the friction between these plates and the ends of the spool causes the latter to revolve with the shaft E until released by a forward movement of thehans dle F Upon the spool G is wound the rope H, which runs over a pulley I at the top of the shears K, erected at or near the bow of the boat, and thence to the hammer L, which may to slide vertically between guides. .I prefer to use as guides the metallic bars 7t, secured to the inner edges of the shears. To the shank Z of the hammer are fastened transverse cleats Z, which overlap the guides on each side and serve as gibs. Filling-pieces Z may be used, if necessary, between the shank and the guides.

The deck and framing of the boat are cut away between the shears, forming a recess in the bow of the boat, as shown. This permits the shears to be brought on either side of the pile or stake X and helps to steady the boat while the pile is being driven.

In front of the shaft E is a shaft M, extending across the frame-work D over the recess in the boat. Secured upon this shaft is a drum N, on which is wound a heavy hawser 0, terminating in a stronghook or grapple 0.

be of anysuitable construction and arranged.

On one or both ends of the shaft outside of the frame-work D is a large spur-gear m. In the retr of these wheels is a counter-shaft P,

which is capable of sliding axiallyin its bearings. A lever P, fulcrumcd in a bracket (1 hasan eyep, encircling the shaft. By means of the lever the shaft can be moved lengthwisein its bearings, the range of movement being suflicient to engage or disengage the pi nionsp with the spur-gears m. At the same time a gear 2 on the shaft P is caused either to mesh with or slide away from a pinion c, secured upon the shaft 0.

Instead of arranging the shaft-Pto slide axially to engage with a fast pinion on the shaft C, I may use a loose pinion meshing permanently with the gear 1) and provided with a clutch actuated by a lever B, whereby the pinion can be coupled to the shaft (3 when it is desired to operate thestake-puller. This lever is shown in dotted lines in Figs. 3 and 4. On the ends of the shaft E, I may place gipsy ends or warping-heads E, by means i of which the boat can be brought to theplace where she is to be moored.

The operation of my machine is as follows: The pile having been brought alongside is hoisted by a rope (not shown) running over a snatch-block I and down to one of the warping-heads E. When the pile has been placed between the shears, the handle E is thrown back, thereby clutching the spool G to the shaft E and winding up the rope H. When the hammer is raised high enough, it can be held by the friction-band while the handle F is thrown forward, releasing the spool and leaving it ready to drop the hammer when the friction-band is slackedott; or the friction-band need not be used at all, the hammer being raised and dropped repeatedly by simply manipulating the toggle-clutch lever F, the engine and the shafts O E running continuously. In this way the piles or stakes can be rapidly driven at the desired places. \Vhen a stake or pile is to be pulled up, the hoolr or grapple 0 is attached to it. The engine is then reversed and the counter-shaft P is slid endwise to cause the pinions p and gear p to mesh with the spur-gears m and pinion a, respectively,

which causes the shafts P and M to rotate,

without stopping the :haft G. hen a loose pinion is used, the d .mn can be started and stopped by thecluteh on the shaft 0, controlled by the lever B. If the machine is to be used, with a non-reversing engine, the rope I-I must be carried under the spool G, as indicated by dotted lines in Fig. 3.

The gipsy ends E are of great convenience in loading material on board the boat, handling it when needed, and other operations besides those previously mentioned.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. An organized machine for driving and pulling piles and thelike, consisting of a boat provided with the shaft E, of the face-plates F F, the spool G, the collar f, the toggle-lever F connected with the collarf, and the bandle F for operating the toggle, substantially as described.

9. The combination, with the shaft E, of the face-plate F, secured thereto, the faceplate F, splined thereon, the collarfihaving the ear f, the toggle F attached to said ear, the bracket d, having a notch receiving said ear, and the spool G between the two faceplates, substantially as described.

3. In apile-driver, the combination, with the shears K having the guides 7c, of the hammer L, having the shank Z, the cleats I, over lapping the guides, and the filling-pieces Z between the shank and the guides, substantially as described.

4. The combination, with a boat having a recess, of the shears K, erected on each side of said recess and serving as guideways for a vertically-movable hammer, substantially as described.

5. The combination, with a boat having a recess, of a hoisting-drum located over said recess, and means for operating said drum, substantially as described.

6. The combination, with a boat having a recess, of the shaft M, extending over said recess and carrying the drum N, and provided with one or more spur-gears m, the shaft 0 and intermediate gearing connecting the two shafts, substantially as described.

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