GATE.

SPECIFICATION forming part of Letters Patent No. 450,569, dated April 14, 1 891. I

Application filed November 19, 1890. Serial No. 371,939. (No model.)

To all 1072 0122, it may concern.-

Be it known that l, ARTHUR W. GRAHAM, a citizen of the United States, residing at Stanberry, in the county of Gentry and State of Missouri, have invented certain new and useful Improvements in Gates 5 and Ido hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention consists in a new and improved gate, which is very simple, strong, cheap, and durable in construction, and which possesses many advantages which will be hereinafter specified, and my invention will be hereinafter fully described and claimed.

Referring to the accompanying drawings, Figure 1 is a perspective side View of my new and improved gate; Fig. 2 is a detail View of the latch end of the gate, and Fig. 3 is a similar View of the top of the stationary posts A.

Similar letters of reference indicate corresponding parts in all the figures.

Referring to the several parts by letter, A Aindicate two parallel stationary posts, which are secured usually in the ground at the hinge end of the gate and are connected at their lower ends by a cross-bar B and at their upper ends by an iron cross-bar O.

The gate itself is formed with the bottom and top cross-bars D D, usuallytwo by six inches in cross-section, and with a longitudinal bar F, two by four inches in cross-section, arranged just above the bottom bar D. At the latch end the gate is formed with the upright F, has a similar upright G at its center and at its rear end has an inclined post H, which inclines back at its upper end, so that while its lower end is pivoted by its pivot-pin I on the center of the bottom cross-bar B its upper part will extend back of the iron crossbar 0, which is secured on the top of the posts A, as shown. As the rear post H ofthe gate is not secured at its upper end to the iron cross-bar C, but passes back of the same, the gate may be made six feet high, if desired.

ires J, which may be either barbed or smooth, are strung from end to end of the gate, being secured to its uprights, and I thus make a gate which is light, strong, cheap, and durable and which will not gather wind or snow.

N, which is pivoted on a transverse pivot m in the lower box and passes through a slot M in the upper box M. A wire 0 is secured at its upper end to the top bar D near the hinged end of the gate, passes around the grooved pulley L in the clevis K, then around a pulley P in a clevis P, which is secured to the top barD at the point shown,and is then inclined down to the lower bar D toward the free end of the gate, where it passes around a grooved pulley Q, mounted in a clevis Q. The clevis Q is adjustably secured on the lower bar D by means of a removable bolt Q passing through any one of a series of holes D formed in the lower bar at that point, and

the forward end of the wire 0 is secured to.

the lower end of the latch-bar N below the box M.

R indicates the stationary latoh-post,against which the free end of the gate swings when closed and to which is secured a catch S, having a beveled end.

It will now be seen that the weight of the gate, acting through the wire 0 on the pivoted lower end of the latch-bar N, will hold the upper end of said bar pressed forward in the slot M of the upper box M, and when the gate is swung closed this bar will come in contact with the beveled end of the catch S and be pressed in at its upper end, sliding in the slot M until it springs behind the hooked end of the catch. The gate will thus automatically latch itself, and to unlatch it it is only necessary to press back. the projecting upper end of the latch-bar N against the pull of the wire 0 to free it from the catch S, as will be readily understood.

The adjustable clevis K can be moved back to take up any slack or stretching of the wire O, and the bracket or clevis Q can be adjusted on the lower bar D to keep the free end of the gate raised to the proper height or level,

as will be readily understood. A pin T on the latch-post R prevents the free end of the gate from being raised.

I am aware that it is not new to construct a gate of this class pivoted at the lower corner of its rear end, having an upper and lower 1 bracket secured upon it and having a rope A, connected at their upper ends by a crossbar 0, a swinging gate pivoted at its lower end between said posts, formed at its rear end with the inclined post H, the upper end of which extends to the rear and above the level of the cross-bar 0, having the pulleys P and Q secured upon its upper and lower cross-bars and having the lower box M and the upper slotted box M at its free end, the latch-bar N, pivoted in the lower box M, a catch S, secured to a suitable stationary post, and the wire 0, connected at its inner end to the cross-bar C, passing around the pulleys P and Q, and secured at its outer end' to the lower end of the pivoted latch-bar N, substantially as set forth.

2. The combination of the posts 'A, connected at their upper ends by a cross-bar U, the adjustable clevis K, having the roller in its closed end and formed with the series of apertures 70 and having the removable bolt K, the gate having the inclined rear post I-I, provided with the pin I at its lower end, having the upper pulley P, having its lower bar formed with the series of holes D and having the lower box M and the upper slotted box M at its free end, the latch-bar N, pivoted in the lower box M a catch S, secured to a suitable post, the adjustable clevis Q, having the roller and the removable bolt, and the wire 0,0011- nectcd at its upper end with the gate, passing around the pulleys L, P, and Q, and secured at its outer end to the lower end of the pivoted latch-bar N, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
