IMPROVEMENT IN GATES.

Specification forming part of Letters Patent No. 41,951, dated March 15, 1864; antedated March 9, 1864.

To all whom it may concern,.-

Beit known that I, D. RWARFIELD, of Muscatine, in the county of Muscatine and State of Iowa, have invented a new and`useful Improvementin Gates or the Means Employed for Opening and Closing the Same; and I do hereby declare that the following` is a full, clear, and eX- act description ofthe same, reference being had to the accompanying drawings, making a part of this specication, in vvhich- Figure l is a side sectional view of my invention,taken in the line a; x, Fig. 2; Fig. 2, an end view of the same, one of the levers being in section.

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

This invention relates to anew and improved means for opening and closing gates to enable a person on horseback or in a vehicle to open or close the gate without dismounting from the horse or getting out of the vehicle.

The invention consists in suspending the gate on an angular pivoted bar placed in a suitable framing and. arranged with a catch or fastening and levers, as hereinafter fully shown and described.

To enable others skilled in the art to fully understand and construct my invention, I will proceed to described it.

A represents a framing,which isv comprised of two upright posts, a a', and two central posts, b. The upper ends of the posts a a are connected by two parallel horizontal bars, c c, the centers of which are supported by posts b.

B is a fence, which is permanently attached to the post a and to one of the central posts b, and closes onehalf the space between the two posts a that is to say, the space between the post a and the posts b, as shown in Fig. 1.

C isa bar which is secured centrally between the two horizontal bars c c by a pivot, d. This bar C is of angular form, being inclined upward at each side of the pivot d, as shown clearly in Fig. l.

D represents the gate, which may be made to correspond with the fence B. This gate has its posts e e extending upward a trifle above the bar C, the latter passing through mortises f f in the upper ends of the posts e e, the posts being connected above the bar C by a crossbar, g, in which two rollers, h h, are tted, said rollers working on away, i, attached to the upper surface of C.

-post a. 4sides of the bar G, so that the latter can be raised from either side ot' the gate, and the in- The gate D is thus suspended on the bar C, andthe former is sulicicntly wide to cover the open space between the post c and the posts b.

The bar Gis allowed to tilt or work freely on its pivot d, and it has aweight, E, attached to it at one end, which weight has a tendency to keep the part of the bar C directly over the space between the posts a' and b down in a horizontal position or a tride below that position,as shown in red in Fig. l. The bar C, when tilted so as to assumeapostion opposite to that above specied,as shownin black, Fig. l, is retained by a catch, F, which is composed of a bar, j, the lower end being secured by a pin or pivot, k, to the outer side of the posta',

yand its upper end passing up through a mortise,Z,in the end of bar 0, which projectsthrough a mortise, m, in the upper end of the post a', the bar j being provided with ashoulder, mon which the bar C rests. The bar C is raised by means of levers G G, which are attached by fulcrum-pins o o to a framing, H, connected to These levers project from opposite ner ends of these levers are fitted in a loop, p,

Vat the'under side of the bar C. In order to disengage the catch F to allow the loaded end of the bar C to fall, two small levers, q q, are secured in post a at the bottom of the mortise m. These levers are both connectedat one end to the bar j by a ring, 1", and said levers at.

their opposite ends have each a cord, s, attached to them, and these cords pass through guides t at the under sides of the levers G G, and project down from said levers near their outer ends, as shown clearly in Fig. 2. A spring, u, which is attached to the outer side of the post a', bears against the bar j and has a tendency to keep theshoulder n of the latter under the bar C at the front edge of the mortise Ztherein.

From the above description it will be seen that'when the loaded end of the bar O is elevated and retained in that position by the catch F the gate D will be in an open state in consequence of the part of the bar C over the space between the posts a b being inclined and causing the gate to descend byits own gravity upon the horizontal part of said bar above the fence, and when the bar G is relieved from the catch F,and the weight E tilts the bar C in the opposite direction, the gate will run down the inclined part of the bariipon 'the horizontal part and be in a closed state, as shown `in red in Fig. 1.

, The levers G G are sufficiently high to be within convenient reaching distance of the rider or driver. The barj of the catch or fastening is drawn back soas to release the bar C by pulling eitherof the cords s, the latter actuating the levers q q, and the latter the bar j.

The gate D is provided with a catch, ctx, at each end, which engage with pins bx to pre-` vent the gate from casually moving When in either an open or closed state. These catches are raised from the pinsb by the tilting of
