CANAL- LOCK.

SPECIFICATION forming part of Letters Patent No. 368,860, dated August 23, 1887 Application filed April 6, 1887.

To @ZZ whom it may concern.:

Be it known that I, 'IHEoDoRE SIDENsoL,

a citizen of the-United States, residing at La Crosse, in the county of LaCrosse and State of Visconsin, haveinvented certain new and useful Improvements in Canal-Locks; and I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The obj ect of my invention is to assist heavyY ladened boats leaving locks on lower level and to provide for the displacement of water in front of boats when entering locks, which enables them to leave locks on lower level and to enter them morequickly and with much less labor than by the means heretofore used.

To this end my invention consists in an im- 4 provement in a lock provided with one or 2Q more tunnels or ducts, beginning below the upper gates of the lock, continuing to overliowchamber, and thence back to the main body of water below the lower gates, the same (for the admission of water therein) being provided with a gate operated by means of a rod which extends above the lock, and to which is attached a hand-wheel for the convenience of adjustmentin opening and closing.

The reason for beginning the tunnel or duct at the upper end is to prevent boats cutting off the outlet. v If the locks are made double length, it willnecessitate another duct or tunnel behind the first boat.

In the accompanying drawings, forming a part of this specication, Figure I is a plan view of the lock; Fig. 2, an elevated sectional view of lock; Fig. 3, a side view.

Similar letters refer to similar parts th rough1 out the several views. y

The double arrows indicate the direction of the natural flow of water in theduct or tunnel when the boat is entering locks, and the single arrow the direction when the boat is leaving lock on the lower level.

In order to fully understand accompanying drawings, A represents water inlock; B, abutment; @,miter-si ll; D,gates; E,wall; F, lever; G, duct or tunnel; H,elbow ofduct; Lgate ofduct; K,overiiowchamber; J,handwheel of rod,and 5J L rod. v

I show in Fig. 1 rod L, which extends Serial No. 233,951. (No model.)

above the lock and is provided with handwheel J. I show in Fig. 2 gate I, which hand-wheel .I and rod L operate for the eduction and induction of water into the duct or tunnel G. I also show in Fig. 2 a plan view of duct or tunnel G in connection with overflow-chamber K. When a boat is about entering lock, gate I is thrown open and the wa ter rushes through it with such momentum (O into duct or tunnel G that it is necessary to have overflow-chamber K to relieve or break up the column or ridge of water that forms therein.

In Fig. 3 is shown a plan view of hand- 55 wheel J, rod L, and gate I.

The duct or tunnel Gis constructed on either or both sides of lock, if necessary, in connection therewith, out of stone or other suitable material. Overiow-chamber K is a part of duct or tunnel G, and is similarly constructed. Canallocks are constructed so as to be used to their utmost capacity. In other words, boats are made as large as they can possibly beto enter locks. The sides and bottoms of each nearly touch.

When a boat is approaching lock, the boatman calls for headway,which enables the boat to enter lock quickly for about eight or ten feet. It then comes to astop, owing to the re- 8o bound or reaction of the breaker, caused by the water being forced by boat against the upper gate, and notwithstanding the strenuous efforts of thehorses it is forced back to the entrance ofthe lock, remaining stationary until thelarge body of water that has been forced in front of the boat can escape. As locks are now constructed this can only be accomplished by the suction of this water under the boat and its escape at the sides thereof, which re- 9o quires some time and considerable effort on the part of the horses or propelling-power. My improvement obviates this difliculty by preventing the formation of a breaker in front of the boat. As the boat is about to enter,lock g5 gate I is thrown open and the large body of water (which forms the breaker) passes quickly through it into duct or tunnel G, thence back into the main body of water below lower gates back of boat on same level with waterin lock, rco thereby 'assisting boat to enter easily. By my improvement in the construction of locks I am enabled to have boat enter lock in about one-third of the time required ordinarily and with very little eiort.

Again, when a heavy-laden boat is leaving lock on lower level, it has the same diiiculty getting out. The water must first pass in lock behind the boat before it can pass out. My improvement remedies this trouble. The gate I is opened andthe water follows in alter the boat through duct or tunnel G (in an opposite direction from its course when boat is entering) to the sumelevel with boat, thereby likewise assisting the same. This, however, is not the case when it enters lock from upper level, as it passes readily in, because it has the combined depth of water in upper und lower level and there is room for its displacement.

As locks are now constructed, they sometimes help boats out of lock by letting waiter in behind them from the upper level; but in dry seasons theyhuve not water to spare. My improvement prevents this, as it utilizes all the water und prevents waste.

Vhat I claim is- 1. The herein-described structural device for the displacement of water in front of boats when entering canal-locks and to assistheavilyladened boats leaving locks on lower level, &c., which consists of a suitable gate and opera-ting device therefor, in combination with overilow-chamberK and duct G, which begins below the upper gate of lock and continues to overliowchember K, thence back to the mein body of water below the lower gates, substantiully as described, und for the purpose set forth.

2. An improvement in canal-locks, consisting of o, gate operated by suitable hand-wheel and rod,in combination with duct or tunnel G and overilowhchamber K, substantially as de scribed, and for the purpose set forth.

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

THEODORE SIDENSOL.
