MARION, `New YORK.

Letters Patent No. 95,083, dated September 21, i869.

IMPROVEMENT IN GATES.

The Schedule referred to in these Letters Patentand making part of the same To `all whom 'it mty` concern Be it known that I, ISAAC A, GIJARK, of Marion,

in the county of Wayne, and State. of4 New York,

have invented acertain new and useful Improvement in Gates; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying` drawings, making part of this specitication, vin whch- Figure 1 shows a plan;` Figure 2, an elevation; and Figure 3, 0l detail view.` 1 Like letters of reference indicate 'corresponding' parts in all the iignres.

This gatto is an improvement upon that patented to V: RL W. Horton, May 19, 1868. In that case an `arrangen'lent of friction-rollers was connected with the 'lower rail of the gate, swinging ofi' andon 'with it, but

.stationary in place when the gate was sliding back.

The only diiiiculty experienced was to always keepthe rollers in place,Y so as to swing back inA line with l thecentral bearing or stndthat sustained it, when the gate received the sliding `movenient.

My present invention is designed to obviate this diiiicnlty,and consists in combining with `the rollers a guide-bar or brace, which is hinged to the post, and swings around with the gate, 4thereby keeping the said rollers always the same distanceffrom the post.

-In the drawingse y y A; indicates the gate, and B B the posts, the'gate being of that kind that slides half-way hack and then I combine with these rollersa brace or bar, (Z, either 0f metal or wood, which hooks, or otherwise connects, at 011e end with the stirrnp c,while at the other it is hinged to the post B, as shown.

By this means, it will be seen that the gate may slide back half way over the rollers b b, and then swing around in the usual manner.

In swinging, it will be noticed that the rollers will be retained, by the brace or bar d, always the' same distance from the post, and hence, in closing, it will strike againover'its bearing or stud j'. l

I thus avoid the difculty experienced in the device at first alluded toas the 'rollers can innwise get displaced. This feature I believe to be original with myself.

vAttire front of the gate, Ilnake one or more of the rails to project beyond the others, as shown at g.

I also cut-an obtuse-angled notch, h., in its upper surface.

In a slot ofthe post B,I hang a catch, fi, provided with a rightfangled corner, k. p i In the forward motionof the gate, the end f/ of the rail strikes the catch and throws ituphand when past-the corner k, strikes into the notch h, and retains the gate against back action.

The novelty inthis case is the extreme simplicity 0f the fastening, requiring no iron, and simply requiring the notching of the rail.

W'hat I claim as my invention, and desire to secure -by Letters Patent, is

The combination of the hinged bar or'brace d with the rollers b l, in the manner described, and for the purpose specified. a 1

1n witness whereof, I have hereunto signed my naine, in the presence of two subscribing witnesses.

ISAAC A. CLARK.
