IMPROVEMENT IN I GATES.

Specification forming part of Letters Patent No. 48.322, dated J une 20, 1865.

T0 au whom 1t m'ay conoem:

Be it known that I, WILLIAM TALLMAN, of Manteno, in the connty ofKankakee and State of Illinois, have invented a new and useful Improvement in Gates; and I do hereby declare that the following isa full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference hein g had to the aompanying drawings, forming part of this specification, in which Figure 1 is an elevation of my gate, showing it when closed. Fig. 2 is an elevation showing it opened half-way. Fig. 3 is an eleration in perspective, showingit wide open.

Similar letters ot reference indicate corresponding parts.

This invention consists in s0 constructing and hanging a gate for a roadway or any other use as to dispense with hinges and enable one to operate it with verylittle exertion, and which when opened wide Will stand at right angles to its position when closed.

A represents the gate. It is framed in any snitable manner, so as to be light and durable. In this example of my invention the frarne is composed of four narrow rails or boards secured near their ends to vertical bars et c, and another vertical bar, 1), is a ttached to the boards near the middle of their length. The bar a-is plaoed at the ends of the rails at the hinder part of the gate, and the bar 0 is plaoed near their other ends, but far enongh from their extremities to permit their ends to projectz, when the gate 1s closed, between the posts G G. These posts are set firmly in the gronnd, opposite to each other, and far enongh apart t0 permit the ends of the gate-rails to pass easily between them. They are connected to each other by pins, which serve to stiff'en them, whileone of the pins also answers for a keeper to the latch E of the gate.

F is a roller, whieh is secnred to the gate, near its front end, between a vertical bar, 1), and the lowest rail of the gate, the roller being v snitably jonrnaled in that rail and in the said bar, as seen in the drawings. The height of the lowest rail of the gate above the ground Will be determined by the length of the radins of the said roller:

B B are gatepcsts, set at the other side of the roadway in line with the gate-posts G respectively, but not oppositeto each other, the front post, B, being set beyond the post B a distance eqnal to the distance apart of their planes from front t0 rear, said distances in each case being a little greater thanthe tl1ickness of the rails of the gate. The posts B B are likewise connected to each other by pins, the upper one, 0, of which passes throngh the angles of the posts, and the lower pin, G, is sustained upon brackets projecting from parallel sides of the posts, so that it liesin a direction at right angles to the gate when it is closed. This pin may be furnished with a'friction-rol- 1er, and I have shown one in this exampleof my invention, designated by the letter D. The pin 0 and roller D are set beneath the second rail of the gate, counting from below, and the adjnstment of the rollers F and D should be such that the gate when closed and resting npon said roller shall be in a horizontal line.

Thc operation is as follows: The gate being closed it is necessary to raise the latch when it is to be opened, and a slight force will suffice 10 withdraw it from the posts Gi and to open it nntil' its bar 0 cornes in contact With the post B. This will snffice for the passage of a man or a horse; but when it is necessary to throw itwide open it is swnng aronnd upon the pin 0, or on the brackets which snstain them, to a line at right angles with its position when closed, as seen in Fig. 3.

Among the advantages of this construction are the economy and simplicity of its parts, the ease ivith which it is operaced, and the little liability to which it is exposed of getting out of order.

It will be seen that the pins O O confine the gate between the posts B B, so that whether opened or closed it is always held npright between said posts.

I claim as new and desire to secnre by Letters Patent- The combination of the gate A, construCted as above set forth, and resting at one end on a roller, With posts B B set in relation to each other, as shown, and operating as described.

WILLIAM TALLMAIT.
