OFFICE,

JOHN VETTERLEIN, OF PLAINFIELD, NEW JERSEY.

IMPROVEMENT IN GATE-LATCHES.

Specification forming part of Letters Patent No. 170,033, dated November 16, 1875; application filed October 22, 1875.

To all whom it may concern:

Be it known that I, JOHN VETTERLEIN, of Pla-infield, in the county ot' Union and State of New Jersey, have invented an Improve` ment in Gate-Latches, of which the following,` is a specification The present invention relates to that class of latches in which there is a vertically sliding` bar with slots through which the attachingbolts pass; and the invention consists in combining, with the vertically-moving latch and latch-block, provided with handles, a slotted case that sustains such latch, a cap to exclude moisture7 and rollers around the supportingscrews, upon which the latchmoves. The end of the latch projects through the case, to enter the notch in the double-inclined catch on the opposite post. This construction allows the Vlatch to be placed at either edge of the gate,

and the latch is operative when the gate opens in either direction.

In the drawing, Figure 1 is a vertical section. Fig. 2 is an elevation, partially' in section. Fig. 3 is a sectional plan; and Fig. 4 is an elevation of the double-inclined catch.

The latch is made of the slotted bar a, from which the handles b project at each side 5 and the latch-block c projects from the face of the bar a at the upper end thereof. The case d is of a size to allow the bar a to slide in it freely. It is slotted at the sides to allow the `handles b to pass out, and there is an opening for the latch-block c, which opening is of sufficient 4length to allow for the vertical movement of i the latch and there is a cap-piece, h, at the upper end of the case, that protects the latch, and prevents the latch being obstructed by an accumulation of snow or ice. The case el is provided with projecting flanges t', through whichthe attaching-screwspassinto the woodwork. There are also screws l, that pass through the body of the case d, and around which are the rollers o, within the slot ot' the latch-bar a. These rollers serve to lessen the friction ot'thelatch-bar as it moves vertically, and it is preferable to employ a back plate, r, of metal between the sliding bar a and the wood-work. The catch-plate s is made with the outside inclines 2 2, for liftinbr the latchbara and its block c; but, instead of the saidinclines 2,terminatin,g` at the notch 3,'that receives the block c, as heretofore usual, I introduce the downward inclines 4 4 between the upward inclines 2 and such notch 3, in order that the latch-bar may have an opportunity to coinmence to fall before reaching this notch 3., and thereby lessen the risl; of the block c jumping` across the notch 3, instead of falling into the same.

rThis latch is very simple in its construction,

cheap, durable, easily applied, and reliable in its action. p

I claim as my invention- 1. The vertically-sliding slotted bar a, latchblock o, and handles b, in combination with the slotted latch-case d, cap-plate h, screws Z, and rollers o, as and for the purposes set forth.

2. The catch-plate s, made with the descending inclines 4 4 between the notch 3l and the ascending inclines 2 2, for the purposes set forth.

Signed by me this 14th day of October, A. D. 1575.

JOHN VETTERLEIN.
