JOHN FILSON, OF MILROY, PENNSYLVANIA.

HANGING FARM-GATES.

Specification of Letters Patent No. 9,576, dated February 8, 1853.

T0 all whom t may concern Be it known that I, JOHN FrLsoN, of Milroy, Miliiin county, Pennsylvania, have invented a. new and Improved Method of Hanging and Latching Gates; and l do hereby declare that the following is a full and exact description thereof, reference bcing had to the accompanying drawings and the letters of reference marked thereon.

My invention consists in providing a contrivance by which a gate may be raised or lowered, and retained at any desired hight, when obstructed in shutting` either by coming in contact with the ground, on account of the hinge-post, or the gate itself giving because of its weight, or, in case of an accumulation of snow and ice, or other obstructions beneath it, and in a contrivance by which the catch of the latch may be raised or lowered tosuit the height of the gate.

To enable others to malte and use my invention l will describe its construction and operation.

r:the gate is made in the common fo an.

My improvement relates only to the hinges and latch.

Figure l, in the drawings represents th-e gate attached to the hinge-pest by my improved method, viz: lst, the double movement lower hinge (B) which by means. of the joint at (d) allows the gate to be raised or lowered at pleasure. This hinge is made of a forked form (C C) as shown, to give it strength. 2nd, the elongated hinge (E) forminga rack (H) working on a pinion (R, F ig. 6)" attached to the ratchet wheel (F, Fig. l). By means of the pinion and rack, in connection with the double hinge helow, the gate can be raised or lowered, and it can be retained at the proper height by means of the ratchet wheel (F) (which is made of one piece with, or firmly attached to the pinion,) and the pawl (G) which prevents its turning and consequently the gate from falling. 3d, the catch (L, Fig. 2)'.

This catch worlts up and down in the slot (a, Fig. 2) in a metal plate (M, Fig. 2) screwed to the post (K). When the catch is stationary the flat part of it Fig. et) which worlts inside the plate (M) and holds the catch in place ,is pressed against the plate by means of a spring placed behind it as seen at C, 8, which represents a part of the post with the plate removed.

The Hat part of the catch Fig. hl) working inside the plate has a protruding point (,A et) and the inside of the plate has a racl (Q, Fig. 5). lWhen the flat part of the catch is pressed outward by the spring (O, Fig. 3) the point. (l), Fig. is caught in the rack (Q) and holds the catch firmly in its place. Vihen it is desired to move the catch up or down it must be pressed back against the spring (O) which will free the point (l), Fig. et) from the rack. The catch may then be moved to the desired height, when the pressure being removed the point (P) is again caughtin the rach and the catch is held stationary. ln this manner the catch may be raised or lowered to suit the height of the gate and of the latch (l, Fig. l) on the gate.

ln order to prevent the gate from being raised by hogs or other animals a piece of wood or metal (J, Fig. 1,) projects from the front of the gate and passes under the catch thus rendering it impossible to raise the gate without its being first unlatchcd.

What l claim as my invention, and desire to secure by Letters Patent is- The lower double jointed Ahinge in combination with the apparatus attached to and constituting the upper hinge, as described for the purpose of holding the gate at any inclination required for the purposes set forth.

JHN FILSQN.
