JOSEPH E. RENK, OF ALBANY, NEW YORK, ASSIGNOR OF ONE-HALF TO RICHARD PARK, OF SAME PLACE.

CANAL-LOCK GATE.

SPEGIFICATION forming part of Letters Patent N 0. 269,712, datedDecember 26, 1882. Application filed May 10, 1882. (No model.)

To all whom it may concern Be it known that I, JOSEPH E. RENK, ot' the city and county of Albany, and State of New York, have invented certain new and useful Improvements in Canal-Lock Gates, of which the following is a specification. I

My invention relates to improvements in the mechanism for operatingcanal-lock gates; and the object of my invention is to provide the means for moving both parts of the gate at the same time. This object I attain by means of the mechanism illustrated in the accompanying drawings, which form part of this specification, and in which Figure l is a plan view of one end of a canal-lock containing my improvements, with the gates opened; Fig. 2, a like view with the gates closed, and Fig. 3 a detached and en-.

larged side view of the the connecting-rods.

As represented in the drawings, A is the usual stone-work ofthe lock; B, the lock-gates; U, the sill-tiin ber; D, a traveling carriage adapted to run on the tracks 6?; E, connectingrods pivoted at one end to the traveling carriage l), and having their opposite ends pivoted to the gates B; F, a winch provided with a drum.f, around which two ropes or chains are fixed to wind in opposite directions. One of the said ropes, G, after passing around the guide-sheaves g, is connected to the forward end of the carriage l), and the other rope, H, is carried around the guide-sheaves h and fastened to the utter end of the carriage D. The traveling cam-age D and connecting-rodsE are placed at the bottom of the lock, where they will not interfere with the passage of boats through the. lock, and the ropes G and H are carried down to the same plane for the same purpose.

traveling carriage for My invention operates in the following manner: When the gates are open, as shown in Fig. 1, the winch F is turned to wind up the rope G and reciprocally unwind the rope H, and thereby the traveling carriage D will he drawn forward on the tracks d and cause the 'connectingrods E to pull the gates B into their closed position. By reversing the move .ment of the winch F, so as to wind up the rope H and unwind the rope G, the traveling carriage D will be forced backward, and by this movement the connecting-rods E will thrust open the gates B from the closed position shown in Fig. 2 into the open one shown in Fig. 1.

1 claim as my invention- 1. The combination, with the lock-gates B, of the operating mechanism herein described, and consisting of a traveling carriage, D, connecting-rods E, winch F, and ropes G and H, all constructed and arranged to operate as herein specified, for the purpose of moving both of said gates simultaneously.

2. The combination, with the lock-gates B, traveling carriage D, andthe connecting-rods E, the latter having their opposite ends pivoted to the gates B and carriage D, as herein described, of the winch F and ropes G and H, said ropes being connected to the winch F in the manner set forth, so that the rotations of the latter will wind up one of said ropes and reciprocally unwind the other, thereby effecting the movement of the carriage D for the purpose of opening and closing the gates B, as herein specified.

JOSEPH E. RENK.
