TO ALL WHOM IT MAY CONCERN:

Be it known that I, HOMER REXFORD, of Sandy Hill, Washington county, and State of New York, have invented a new and improved Oanal-Lock-Gate Step andI do hereby declare the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon. t

The nature of my invention consists in connecting the step on which the gate rests and swings with the metallic'box fitted in the heel-post of the gate, to rest upon the pivot of'the step, which enters the socket of' the box, in such a manner that the step will remain attached to said boit when Ithe gate is being putin its proper position, and'when removed from its place by accident or design.

lo enable others skilled in the art to make and use my invention, I Awill proceed to describe its construction. I make in the socket ofthe box, heretofore inserted in the lower end of the heel-post of the gate, an annuler slot, at about one-tbird of the height of said socket, and of suiicient size' for the feather," herein described,

to move in freely at all times; and from the lower end ci' said socket I make a vertical slot up into said annular slot, of sulicient size to receive said feather, and allow it to pass into said annular slot.

Upon the side of the common' pivot of the ordinary step, I make a Afeather, of suilicient size to ft saidv vertical slot, and pass into said annular ring or slot, and there be made to revolve so freely that said box cannot, at any time, rest upon said featherg and, at the same time, the ifeather will be of suilicient strength to sustain the weight oi' the step," in its connection with the box, at all times.

In the accompanying drawingsl 'B represents the pivot, .featherf and Abase combined, forming the step."

A represents the steppivot. F represents the fcather." C represents the vertical of the metallic box. E -represents the annular slot in the socket of the box. D represents the vertical slot. G represents the socket of thc box. v v J represents. the heel-post of the gate, with the box and step connected, and when in position.-

Having thus malle E and Din the socket of Gr, I x the metallic box in the lower end of the heel-post of thc gate, with D in the direction of 4the front of the heel-post ofthe gate, and then4 connect B with said box by passing F, on the-pivot of the said step, .through D, into E, and, by a partial revolution of said step, sufficient to bring said lfcathef' opposite to D in said annular. slot, the connection is completed, and said gate can be placed in posit-ion, or removed therefrom, Iwithout said step and box being disconnected, whereby much time, labor, and expense are saved in shipping the lock-gatc,an'd in replacing it when it is removed from its proper position by accident or from other causes. l

I do not claim 'the box and step now in use in connection with the support of canal-lock-gates; but I claim the construction and arrangement of the step B, with its pivot A and feather I", when combined with the metallic box C, constructed with its annular slot- D, in the manner and i'or the purposes herein described.
