Description

THoMAsnHALL, `or.

i Lette/rs Patent No. 90,839, 'dated June 1, 1869.

CLRCLEVILLE, oHIO.

i IMPROVEMENT IN FARM-GATES.

The` Schedule referred to in these Letters Patent and making part of the same.

To all 'whom 'it mwy concern:

Be it known that I, THOMAS F. HALL, of Circleville, in the 'county of Pickaway, and State of Ohio, 'have invented new and useful' Improvements in Farm- Gates and I do hereby. declare that the following is a full and exact description of the same, reference being had tothe accompanying drawings, making part of this specification, in which- Figure l is a front elevation;

Figure 2 is a top view; and

Figure 3 is a section on line x of iig. 2, showing how the gate is held suspended by the springs H H.

Like letters refer to like parts.

My invention relates to that class of farm-gates that will rise and fall vertically between two posts, and while up for the passage of vehicles, is partially sustained by weights'.

In the drawing- A represents the posts, and

B, the braces.

The posts may be set in the ground in the usual manner, or framed into a sill.

The tops of the posts are connected by a double arch-way, C C, having sufficient space between them, shown in tig. 2, to allow the thickness of the gate to pass between them.

At the centre of this arch the pulleys D D are mounted, as shown, and for purposes hereinafter described.

There are also two other pulleys, YE E, located, respectively, near the top and in the vertical centre of each post. r

The gate is shown at F, and may be made of horizontal barsand vertical slats, or in any other convenient style. The ends'are tted to run in grooves,'or guide-ways upon the inner surface ofeach post.A

A catch, G, of any convenient form, is placed upon the top of the gate, and secured near the middle; and this catch, when the gate is raised, as hereinafter described, eug`ages between twov springs, H H, which are situated between the pulleys at the top of the arch.

H' H' are springs,-which are secured to arched pieces O O, and so arranged as to bear upon the springs H H, near the points-where they grasp the clutch G, so they may insure the holdingof the gate in its position bythe springs H H until it is released by pulling the cord L.

The weights that partially balance the gate are shown at I I. From each' of these a cord passes over the pulley E, and is attached tothe 4lower corner of the gate, respectively, as shown.

The pulleys D D carry each being attached to the middle of the gate,

a cord, K, one end and the other end to a-post convenient to the approach of the gate from each direction. y

By pulling upon either of these ropes, the gate will be raised, asshowu at F', in fig. 1, and carried up until the catch G engages with the springs H H, where it is held until released.V This is accomplished by means oi ropes, or cords, L L, o ne end of which is attached to the springs H H, and the other to a postconvenient to the place of exit.v By pulling upon either of these ropes, the catch Gr is released from the springs H H, and the gate descends by its own gravity, which should be a little greater than that of the weights, thereby giving it an easy and regular movement.

What I claim as my invention and improvement, and desire to secure by Letters Patent, is

1. The posts A, in combination with the arch O and pulleys D and E, as specified.

2. The combination of the gate F with the posts A, arch C, aud pulleys D E, as speciiied. 3. The combination of the catch springs H, as set forth.

4. In-combination with the elements of these preceding clauses, the ropes K and L, and weight I, as speciiied. l 5. The arrangement of the springs H H, for the purpose specified.

In testimony whereof, I have signed my' name to this specification, in the presence of two subscribing witnesses..

THOMAS F. HALL.

Witnesses:

JEREMIAH HALL, Gao. W. YOUNG.
