Specification of Letters ratent no. 12,790; dated May 1, 1855 y To all whom it may concern: 1

.Be it knownthat we, Coma FLiUs L. HAR- .SEN and Mosi s R. BnAILnrQof Norwalk, in themcounty ofjHuron and'St-ate of Ohio, have invented a jnewwand useful. Improvement in Gates, and we' do hereby declare fthat the following is a full, clear, and exact descriptionof the construction andbpeia: tion of thesame, reference being had to the annexed drawing, forming part of this speci-. fication, which represents an elevation of the. i ate.

Thejobject of our invention isPthe con-f struction' of self supporting-gates which nary. gates. inoperative; 1

so thatthe attachment of the lever and rod shall form the fulcrum of the lever, the arrangement being such that a suitable movement of the long arm of the lever will by depressing the connection of the diagonal rodandlever draw the two stiles together and. elevate thegportionof the gate most remote from the hingesand thus free the catch ufromits cavity in thelpost and by the elevation of thegate, permit it to pass over an obstruction in opening; the construction and. arrangement being such as will be hereafter fully set forth.

f To enable othersskilled in the art to make anduse our inventionwe will proceed to describe its construction and operation.

In the drawing a a arethe stiles of the gate which are connectedby the planks 0,

which works againstthe plate 79 and under the guard Theelbow of this lever is con: nected with the upperportion of the stile a by the rodR, renderingthe distance between the two points of attachmentinvariable and Attached to the stile a; is the bent lever L converting the bent lever L into a lever of thefirst order, its fulcrum being at 2", the attachment of. the rod R and .elbow of the over an obstruction in opening.

The operation of this improved gate is as followsThe moving of the lever L as shown by the arrow will raise the stile a as above set forth, and allow the catch to clear the notch in the post P, when the gate is freely swung open. On closing the gate a reverse motion of the lever L permits the catch to drop into the securing notch. In this movement of the stile a the several boards of which the gate is composed, turn about the rivets or bolts 6 f by which they are connected; the attachment of the plate 77 and guard 9 moving in curved slots made in the board to which they are attached.

. One of the great advantages of this gate is its power to support itself without the sinking of either stile, as from its peculiar construction no sag can take place in any of its parts, the gate when shut being supported by the hinges h 72,, and the rigid catch 72.

The principal advantage arising from this construction consists in the ability of the gate to pass over snow drifts and otherobstructions to the opening of ordinary gates, the, simple movement of the lever L carrying the gate above all obstacles.

What we claim as our invention and desire to secure by Letters Patent, is r The construction of farm gates with their several parts loosely connected, combined with the bent lever L and diagonal rod R arranged and operating so as to elevate the gate in opening for the passage of obstructions substantially as hereinbefore set forth.
