IMPROVEMENT I N FARM-GATES.

Specification formingr part ofLetters Patent No. 147,220, dated Februaiy 3, 1874; application filed October 11, 1873.

fo all whom it muy concern.: y'

Be it known that I, WILLIAM Bo fMAN, of Staystown, in the county of Somerset and State of Pennsylvania, have invented a new and `valuable Improvement in I `arm=Gates and Figure l ofthe drawings is a representation ot' a view of my gate from the inside. Fig. 2 is a view of the same from the outside. Fig. 3 is a detail view.

This invention has relation to gates which are swung from one side; and consists in combining with a gravitating latch-lever a latclr bar, which extends to the upper end of the gate, and catches behind a pulley applied on the gate-post, thus affording a double latch which operates simultaneously, as will be hereinafter explained. 4

rl`he following is a description of my invention:

In the annexed drawings, A represents a swinging gate, which consists ot' horizontal bars secured at their ends to vertical bars, and

. sustained against sagging by means of a diagonal rod, D, having nuts a a 011 its ends. rlhe brace-rod D passes through eyes secured into the horizontal gate-bars, and through the upper and lower ends respectively, of the vertical bars, and prevents the free end of the gate from sagging. B represents the post to which the gate is hinged, and B the post to which the gate is latched when shut. C represents a latclrlever which has its fulcrum at I), and which has a weight, W, applied to its longest arm. The shortest arm ot' lever C passes through a sta-ple, c, and when the gate is shut engages with a beveled catch, e, on the post B. To this lever-latch C, the lower bent end of a latch-rod, g, is connected, which rod is recessed into the upright oi' gate A, as shown in Fig. 3, and guided by eyes 'i t', xed into this upright. lhe upper end of the rod g is bent so as to form a hatching-nose, which will pass behindan anti-friction roller, d, near the upper endof post B', when the gate is shut, and thus latch the upper end of the gate at the same time the latch C engages with the catch c.

The upper latch is intended to afford additional security to the gate when shut, and also to relieve the lower latch from strain, and the weight 'w is intended to latch both the rod g and the lever-latch C, and keep them latched when the gate is shut. Should the gate sag, from any cause,it can be set up again by tightening the Init at the upper end of one of the uprights.

That I claim as new, and desire to secure by Letters Patent, is-

'Ihe latch-rod g, constructed with a nose, gf, on its upper end I'or engaging with a roller, d, in combination with a gravitating lever-latch, C, and weight fw, as and for the purposes described.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

WILLIAM BOIVMAN.
