GATE-LATCH.

SPECIFICATION forming part of Letters Patent No.l 779,963, dated January 10, 1905.

Application filed June 11, 1904. Serial No. 212,175.

T0 all whom it may concern,.-

Be it known that I, NELs PETERSON, a citizen of the United States, residing at Meckling, in the county of Olay and State of South Dakota, have invented a new .and useful Gate-Latch, of which the following is a specification.

The invention relates to improvements in gate-latches.

The object of the present invention is to improve the construction of swinging gates, more especially to provide a simple, inexpensive, and eflicient locking mechanism for that class of swinging gates which are adapted to be raised and lowered to arrange them at different elevations in order that they may swing' clear of obstructions or afford a passage-way for small animals.

A further object of the invention is to provide a locking device of this character adapted to engage a latch-post at any point throughout the length of the same and to enable a plurality of latch-bolts to be simultaneously operated. i

With these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion, size, and minor details of construction within the scope of the claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure 1 is an elevation of a vertically-adjustable gate provided with locking mechanism constructed in accordance with this invention. Fig. 2 is a detail plan view illustrating the construction of the latchpost and the means for operating the latches. Fig'. 3 is `a detail view of one of the latches and the means for operating the same. Fig. A is a horizontal sectional view of one of the latches, showing the bolt in engagement with the latch-post. Figs. 5 and 6 are detail views of the windlass for raising and lowering the gate.

Like numerals of reference designate correspending parts in all the figures of the drawings.

1 designates a swinging gate, which may be constructed in any desired manner and which is hinged to a post or upright 2 by means of a pintle-rod 3, which passes through suitable eyes of the gate and the post, as clearly indicated in Fig. 1 of the drawings. The inner end bar of the gate is connected with one end of a rope, cable, or other flexible connection L1, which extends upward to a pulley 5, and the said flexible connection extends from the pulley 5 to awindlass 6, mounted on the gate at the center thereof and provided with a suitable pawl-and-ratchet device, whereby the gate is held at any desired elevation. A collar 7 is arranged on the pintle-rod above the lower eye of the gate and is provided with a setscrew for engaging the pintle-rod, whereby the collar is rigidly connected to the same to form a stop for the lower eye for preventing the gate from being raised.

The gate is provided with a plurality of latches, each consisting of a slidable bolt 8, mounted within a sectional casing 9 and provided at its outerl end with a tapering notch or recess l() for the reception of an outwardlyextending flange 1l of a bar l2, which is T- shaped in cross-section to form a continuous keeper. The bar 12, which is provided with laterally-extending iianges, is secured to the front of a latch-post 13 and extends substantially the entire length of the same, being preferably terminated short of the surface of the ground, as indicated in Fig. 1 of the drawings. The latches are preferably located at the bottom of the gate and at the upper portion thereof, as shown, and the sectional casings, which enable the parts to be readily assembled, are secured to the gate by means of clips 14, embracing the sections and passing through upper and lower eyes 15 of the same, as clearly shown `in Fig. 3. The clips have threaded ends and are provided with nuts for engaging the gate. Each bolt, which is slidable within its casing, is provided with alongitudinal recess or opening 16, and 1t has a series of teeth 17 extending along the s1de wall ofthe same to form a rack which is engaged by a pinion 18. The pinion 18, which is rotated by the means hereinafter described, is adapted to reciprocate the latch-bolt to carry the same into and out of engagement with the vertical flange of the latch-post. The vertical flange is tapered or wedge-shaped and is firmly engaged by the latch-bar when the gate is locked.

The pinions 18 of the upper and lower latches are provided with polygonal openings for the reception of polygonal portions of a vertical shaft 19, which is journaled in suitable bearings of the casings at the top and bottom thereof. The vertical shaft is supported in position by means of an adjustable collar 20, provided with a set-screw 21 and arranged upon the upper latch-casing,'as clearly shown in -Fig. 3. The vertical shaft is loosely arranged within the bearing's of the latch-casings and is adapted to be readily removed therefrom. The vertical shaft is operated by means of an arm or handle 22, having one end forked or bifurcated to receive the upperend of the vertical shaft and pivoted to the same by a pin 23 or other suitable fastening device. The upper end of the shaft is preferably squared, as shown in Fig. 2, and the arm or handle enables the shaft to be readily rotated to move the latch-bolt inward and outward. The arm or handle is locked against accidental movement by means of a curved bar 24, provided at its ends with perforated enlargements or 'ears 25 for the reception of screws or other suitable fastening devices for securing` the bar 24 to the gate. The bar is also provided with depending ears 26, which are secured to the gate, as indicated in Fig. 3 of the drawings, and it extends horizontally from the gate, being provided at intervals with upwardly-extending' lugs or projections 27. The lugs or projections are spaced apart to receive the handle or arm 22, and they are adapted to lock the same. The handle is retained in engagement with the horizontal bar by gravity, and it is readily lifted out of engagement with the same when it is desired to partially rotate the shaft for reciprocating' the bolts. When the shaft is turned, the bolts, which may be of any desired num ber, are simultaneously reciprocated to lock or unlock the gate.

The latches are adapted to engage the latchpost at any point, and the gate may be readily secured to the latch -post at any point throughout the length of the vertical flange. The vertical flange also forms a guide, and the gate may be readily raised and lowered while in its closed or locked position.

The gate is adapted to be adjusted vertically to clear obstructions, such as snow, and also to provide a passage-way for small animals, such as sheep and hogs, when it is desired to separate the same from other stock.

Having thus fully described my invention,

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