TO ALL WHOM IT MAY CONCERN:

Be it known that I, MARTIN BISHOP, of Putnam, Muskingum county, Stato of Ohio, have invented improvements in Canal-Locks and Submerged Gates for eanalsor rivers; and I do hereby declare the following to be an exact descriptionthereof, reference being had to the accompanying drawings and to the letters of reference marked thereon, making a part of this specification;

The natnge of my invention consists in the construction of the gate, withits shaft and arms `fitting between subdivisions, and resting below the bottom of thecanal; also, the corresponding shaped chambers beneath the bottom of the canal, the adjustable wickets, and the movable device for making the gate` water-tight`when raised; and the object of my invention is to have a perfect r lock when the gate is up, and when down it is a canal for the water to pass along with itsl regular flow; or when submerged in a river it is'a complete shipchannel or lock whenever required.

A represents the side walls. B are openings or chambers in the walls'for the purpose of containing thehoisting machinery or apparatus,.such as a screw, C, with a travelling-burr, D, movingup or down, with side pitmen E as guides to operate their movements on the screw, as the screw is operated by the wrench or levers G above. To the gate K a chain, H, and weight, J, are attache-fl to raise andcou'nterbalanee the raising ofthe gate K. The gate K is attached to a shaft', L, extending across the lock, located at the bottom of the lock'and fastened into the walls at each end. `On this shaft L the arms M of the gate operate, and radiate to the circular periphery or face ofthe gate. The arms, fitting in between the subdivisions N, are built`of masonry, iron, or timber. The centre of the gate is braced by cross-timbers P. Q Q are wickets, connected by shafting couplings extending across the lock to allow the water to pass down in to and through the lower chamber 'R that is located underneath the bottom of the lock, shaped similar to the shape o f the gate, for the gate to rest in when lowered, which allows the upper side lof the gate to form the ilooring of the lock. A fiangedand grooved closing apparatus or device, S, on each side ofthe wall, shaped similar to the convex face of" the gate, and movable, makes the gate water-tight when raised, by closing the'joint between the gate and the wall. I also have a rack and pinion, T, attached to the inside of the face of the gate, thatsmay be used instead of the screw, if deemed necessary, or I may be enabled to use this rack and pinion with' a chain and weight, or operated by the power of the water upon a wheel above, or bevel gearing.

What I claim as my invention, and desire to secure by Letters Patent, isi 1. The construction of the gate, operating on its shaft L, with its arms M fitting Vbetween thcdivisions N,

and having bracingl? P, and resting below the betteln of the canal inthe correspondingly shaped chamber R, as herein described and for the purpose set forth.4

2. I also claim the chamber It, constructed as described, with subdivisions NN located b encaththe bottom of the canal, as herein described and for the purpose set forth.

3. I also claim, in combination with such ehnmberand gate, the adjustable wickets, operated as described and for the purpose set forth. l i

4. I also claim, in combination with the gate, the movable device or apparatus S, as herein described and for the purpose set forth.

MARTIN BISHOP.
