Specification of Letters Batent Ni'o. 687,.dated April 13, 1838.

To all "whom it may concern:

Be it known that I, FRANKLIN LIVING- s'roN, of the town of Waterford, in the county of Saratoga and State of- New York, have invented anew and useful improvement to prevent the gudgeons, steps, andcollars of paddle or valve gates, such as are usedin canal navigation for filling and emptying canal-locks, from wearing and also an improvement for opening and shutting the same by the horizontal application of the screw and lever combined, which is described asfollows, reference being had to the annexed drawings of the same, making part of this specification.

The nature of my improvement consists in the application of friction boxes and collars to the gudgeons (orpivots, collars, and steps, of paddle gates). The improvement of opening and shutting the'same consists inthe application of a screw and nut attached to a lever, to be applied to gates standing perpendicular. a

To enable others skilled in the art of making lock gates to make and usemy improvement and invention I will proceed to describe the construction and operation of the ing at the same time, the size andshape of said friction boxes and collars to suit the gudgeons of the gates. made in any suitable form and thegudgeons or pivots onwhich it turns may be attached in such a manner as'would suit the constructor best, and the gudgeons may be attached to any part of the wicket gate, or cast on the gate, and they may be made of any suitable kind of metal and so may the gates be made of metal (either cast or wrought iron, or wood: and iron combined).

I will describe a gate together with the gudgeons or pivots on whichit turnsmade of an entire piece of cast metal, the gudgeons cast on'the gate. The following isa description of one two feet square, the plate A Figure 1 should be about one inch and a quarterthick in a line with the gudgeon B. The vertical edges ofthe gate or plate should be from half to five eighths of an The gates may be inch thick, and increased in thickness to- Ward the middle, so as to make thefront andback of the plate a littleconvex instead of flat. Thetop gudgeon should be three inches long andthree and three fourths of an inch thick in diameter, in the topof this gudgeon is a mortise G one inch and a quartensquare, and nearly three inches deep to admit of a wrought iron rod that is to turn the gate, where the gudgeons join the gate it should be increased gradually in :thickness to. the full: diameter of the gud- Qgeons, so that there maybe no weak place in consequence of any jmetal, and on the side'of this gudgeon there must be a crease or groove cast or madein git so as to receive aicorresponding tongue EF cast or made on the inside of the friction ibox E Figs. 2 and 5 that surrounds this igudgeon andtprotects it from wearing. The

Ebiottom gudgeon B Fig. 1 should be about Etwo inches thick where it joinson to the gate land slanted: off to about one and a half {inches at the lower end and two inches long. The collar F Figs. 3 and 5 in which the lupper gudgeon works should afford to it abearing of" about three inches-it may be formed one half" in the metalTframe'that, surrounds the sluice or may be firmly fasltiened to it. Where there is no metal frame then this collar is a separate piece of casting i aboutv twelve or thirteen inches long, having a bearing of about three inches fastened: to ithe top off thesluice by means of bolts and jnuts or spikes, and in this collar there is ;an inner collar, G Figs. a and 5 of corresponding circle'to the inside of the collar F sudden offset in the: i

and ofadifferent kinds of metal. It must be made to suit and fit the-circle in the collar F and at the sametime to correspond with the friction box E (that protects the gudgeon from wearing) this friction box, or bush E is a circleQthe inner friction collar Gr Figs. 4-,; and 5 ismadein two 'parteach a half circle with tongues I on each the collar Gr is made in thesame shape and size in every particular as the one just de-- scribed so that when these two sections or semi-circles are put in their places they form a. circle around the friction box or bush that surrounds the gudgeons of the gate. I prefer thus to make these two sections of the same size and shape on account of re 'quiring but one pattern for both, thereby avoiding any mistake should one break or be worn out, and it become necessary to replace it by another under water, and again when repairing the canal in the spring (as is usual) there will be but one kind of collar to carry about by the workmen, by this method all confusion ormistake is avoided. The friction box E that surrounds the upper gudgeon (and protects it from wearing) may be made of cast, or anyother metal, and must be about an inch thick of the same length and a little larger in diameter so that it may be slipped off and on easily by means of the thumb and finger at pleasure under water and on the inside there must be cast 25 a tongue to correspond with the groove in the gudgeon by which it is'made fast to itand kept from turning, and when the gate is turned this box turns with the gudgeon and the wearing thus takes place on the outside thereof and not on the gudgeon, and likewise the outer collar F is in a similar manner protected from wearing by the inner collar G.

I The step M Fig. 6 to receive a friction box Fig. 7 and bear up the gate and rod that is to govern the gate, should be cast of metal of suitable size and shape firmly fastened to the bottom of the sluice by bolts.

This step should notbe less than one and a half inches thick where it receives the friction box the hole in the same being governed in size according to the size of the friction box and gudgeon that it is to receive, twelve inches long and beveled off toward the back end one inch thick and three broad with two inch holes in it to secure it to the girt at the bot-tom of the sluiceand in said hole M Fig. 6 there must be a notch or groove '12 cast or made in the side thereof to receive a corresponding tongue 10 on the friction box Fig. 7 that enters or sets in to this step to prevent it from turning and wearing.

The friction box. Fig. 7 that sets into the above described step ismade of cast iron, and has a flange K cast on it of about 2 inches broad, and all parts of it is about one half inch thick, this box has a bottom to it (thereby increasing its durability) and a tongue p cast or fastened on the outside to correspond with the groove cast in the step, by which it is held stationary, in the hole of the step, consequently the step cannot Wear, and the flange to the box may be made larger or smaller as the nature of the case may require; but the box. and the hole in the step must always be guided in size according to the size ofthe lower gudgeon of the gate.

The friction box Fig. 8 (for preserving the lower gudgeon from wearing) is made a little larger than the gudgeon and the hole in the box must be a little ovaling on the front side of the box, so as to let the gate pitch a little forward to clear the collar above, that it may be taken out and another one put inits place with ease, and about one sixteenth of an inch deeper, also with a bottom so that the bottom of the gate rests on the flanges of this friction box and this box must be set intothe beforementioned friction box (that preserves the step from'wearing) consequently must be of such size as to be inserted into the before mentioned box, and the flanges mustcorrespond in'size to each other so that the bearing and wearing will be equal, and, on the top part of the flange (one each side) there must be ste'adying pins or 'knobs 9 cast of about half inch high, so that by means of said pins when the gate is in its place the gudgeon will set in this friction box and as the gate turns this box is made to turn on the friction box that protects the step from-wearing, consequently the friction or wearing comes on the two friction boxes thereby both the lower gudgeon of the gate and the step is entirely protected from wearing. These wicket gates vA Fig. 9 are turned by insetting vertical zontal arms P at right angles to the same the ends of said arms being attached to a horizontal rod Q moved by a horizontal screw R turning in a nut which thus turns all the gates together.

The boxes for horizontal gates will be made similar to those represented at Fig. 10, in which the inner box S on the gudgeon is made like box E Fig. 2and the outer box T in which vsaid box S turns has a tongue on the outside fitting into a corresponding groove. in the collar 9 fastened to the frame of the main gate.
