IMPROVEMENT IN GATE-LATCHES.

Specification forming part of Letters Patent No. 190,976, dated May 22, 1877; application filed October 21, 1876.

To all whom it may concern:

Be it known. that I, JOHN NEILL, of St. Joseph, in the county of Buchanan and State of Missouri, have invented a new and valuable Improvement in Gate-Latches; and I do hereby declare that the following is a full, clear, and exact description. of the construc tion and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representationof a vertical section of the catch-plate. Fig. 2 is a face view of the same with faceplate partially removed, and sectional view of the latch-plate. Fig. 3 is an inside view of the face-plate. Figs. 4, 5, and 6 are details.

This invention has relation to means for fastening gates; and it consists in the combination, with a recessed catch-plate having an angular footflange and a ribbed face-plate, of a slide and spring. It also consists in certain other details of construction, whereby very desirable results are obtained as hereinafter shown and described.

In the accompanying drawings, the letter A designates the latch or tongue. Its forward end a is made broad. and provided with an angular border, b. At its rear end the latch is provided with journals 0. B indicates the attachment-plate, whereby the latch is secured to the gate. This plate is provided with a central rectangular enlargement, O, which is recessed from the rear, as shown at d. The front wall of this enlargement is slotted vertically at e for the passage of the latch, ledges or shoulders f being left on each side of the slot. D D represent journal-seat blocks, each of which is laterally recessed toward the front on the inside, as shown at g, and provided with a journalseat aperture, h. When these blocks are brought together on each side of the latch, the apertures h receive the journals of the latch and form seats therefor. These blocks are designed to be introduced with the tongue or latch into the recess d, and to fill the latter neatly. The plate B is provided with screw-holes k, for the passage of the screws, whereby it is attached to the gate. The blocks D D are held in the recess d, between the material of the gate and the ledges f of the attachmentplate. E represents the catch-plate, which is designed to be secured to the gate-post. its upper end is longitudinally recessed, as shown at F, for the reception of the pressure-slide G, the marginal wall w of the recess being curved outward at the corners thereof, as shown at u, to provide inside spaces for the shanks of the fasteningscrews, which are designed to pass through the holes 2. The pressure-slide G extends downward through the opening H at the lower end of the recess F, and terminates in a transversely-angular end, K, which, in its lowest position, abuts against the shoulder l of the plate. Above the slide is arranged the spring L, which serves to press the former downward with a certain amount of elastic force. Over the recess F is fitted a face-plate, P. which is provided at its corners with screw-holes 2, cpposite the holes z of said recess, so that the same screws which serve to fasten the attachment to the gate-post will hold the face-plate to its position. On the inside face of this plate are arranged ribs 1, which extend longitudinally, and form a slideway for the pressureslide G. Side and end lugs n, on the inside face of said plate, serve to engage with marginal notches n of the wall of the recess F, and prevent all lateral and longitudinal movement of the face-plate when duly fitted in position. At its lower end the face-plate is extended, as shown at R, to form an exterior guard for the latch and slide in their relative movements.

T represents the lower end or foot of the attachment-plate E, which is usually provided with a screw-hole, h. Above this is arranged, opposite the transverse angular end of the pressure-slide G, a transverse A-shaped flange, V, which extends outward from the plate underneath, and at a short distance from the angular end of said slide. Between the latter and the A-shaped flange a transverse passage orthroat, q, is formed, having on each side a wide opening, which gradually decreases toward the central line, as shown. When the gate is closed the tongue or latch A is designed to pass between the angular slide and the flange V until the enlarged portion or head a is entirely through and engages with the bevel of said flange, which lies on the opposite side from the gate. In this position the spring presses the slide down upon the back of the latch, and holds the latter to its engagement with the catclrflange V.

In order to lock the gate, a set-screw, J, is provided in the wall of the recess F, to engage with the slide G when in its lowest position.

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

1. The combination, with the recessed catchplate E, having the A-shaped foot-flange and the ribbed face-plate P, of the slide G and spring L, substantially as specified.

JOHN NEILL.
