IMPROVEM ENT IN GATES.

Specification forming part of Letters Patent No. 222,806, dated December 23, 1879; application filed October 24, 1879.

To all whom it may concern Be it known that I, JAMES G. WILSON, of Streator, in the county of. La Salle and State of Illinois, have invented certain new and useful Improvements in Gates; and I do 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, reference being bad to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to such swinging gates as can be adjusted so as to swing at different elevations from the ground, thereby providing for operating the gate with the same case in the winter, when there is snow on the ground, as at other seasons, and also affording the opportunity of allowing smaller stock, such as pigs and sheep, to pass under the gate when elevated, while still preventing the passage of larger cattle.

My invention consists in linking an adjustable gate to a permanently-located spindle, so that the gate will, in adjusting it, rise and fall with a motion parallel to the spindle, which affords the opportunity of a lateral adjustment of the gate to a limited extent, to compensate for any spreading of the gate-posts by sagging or other causes.

' It further consists in forming a lever-arm on one of the links of the gate, by which it may be raised and lowered and held in any desired position within its range of motion, certain means being provided for locking the lever at any point.

In the annexed drawings, Figure 1 is a front elevation of my improvedgate, showing it in the depressed position. Fig. 2 is a t-ront elevation, showing only the lower portion of the gate, and that in its elevated position. Fig. 3 is a horizontal section in the plane indicated by line as x of Fig. 1.

The same letters of reference are used in all the figures in the designation of identical parts.

The gate A operates between the posts 0 and D. It is connected to aspindle, B, which is permanently hung on the post D by means of brackets, which are secured to the post and have wrists engaging bearings of the spindle top and bottom.

Any other known means may be employed to hang the spindle on the post D in lieu of the means shown.

The gate is connected to the spindle by links E and F, of which a set may be used on each side of the gate, as shown in the present example, although one set will answer the purpose. Where but one set of links is used it may be best to arrange them in mortises in the spindle and the adjacent stile of the gate. The lower link, F, on one side of the gate, is elongated beyond the point where it is pivoted to the gate, to form a lever-arm, F, by means of which the gate may be conveniently elevated.

A sliding clamp connects the outer end of lever-arm F to a slotted arc, Gr, fixed on the gate, the said clamp being provided with a thumb-nut, G, for securing lever-arm F to the are at any point in the range of motion of the lever-arm, the limits of which are determined by the gate coming in contact with the spindle B in its highest and lowest positions.

The gate is provided with a spring-catch, H, provided with inclined ribs h h, between which a space is left to allow the catch to lock on the detent I on gate-post O. The detent I is made so long that the catchH may engage it, whether the gate be in its highest or in its lowest position.

In order to raise the gate from its lowest to its highest position, or to lower it from its highest to its lowest position, it must first be opened; but any slight lateral adjustment of the gate, for the purpose of compensating for a spreading of the posts, may be effected while the gate is closed.

Means other than a lever-arm and an arc and clamp may be used for adjusting the gate and holding it in any required position with reference to the spindle; and where a leverarm is used to adjust the gate on the spindle to which it is linked, means other than an arc and clamp may be used to lock the lever-arm at any required point. Such modifications of details will readily suggest themselves to persons skilled in the art, and would, at most, constitute only improvements subordinate to this patent. a

mounted so that the upper end of thegate might be connected to the upper bar and the lower end of the gate to the lower bar.

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

1. The combination, substantially as before? set-forth, of the permanently-located spindle, the swinging gate, and the links for connect= ing the gate to the spindle and providing for V adjustment of the gate.

7 2. The combination, substantially as before set forth, of the permanently-located spindle, theswing'ing gate, the links connecting the gate to the spindle, a lever-arm on one of said links, and means for securing the lever-arm in any position to which it may be turned in adjusting the gate.

In testimony that I claim the foregoing I have hereunto set my hand this 20th day of October, 1879.
