GATE LATCH AND OPERATING DEVICE.

SPECIFICATION forming part of Letters Patent No. 561,732, dated June 9, 1896.

Application filed January 16, 1896. Serial No. 575,767. (No model.)

To aZZ w/wm it may concern.-

Beitknown that I, THEODORE SMITH, a citizen of the United States of America, residing at Georgetown, in the county of Vermilion and State of Illinois, have invented certain new and useful Improvements in Grate Latches and Operating Devices, of which the following is a specification.

My invention relates to certain improve ments in gate latches and operating devices for opening and closing gates; and to such end it consists in constructing a device'which shall be extremely simple and efiective and shall be capable of being attached to any gate.

The invention is illustrated in the drawings presented herewith, in which- Figure 1 is a perspective view of a gate with my attachments secured thereon and showing the gate in a closed position. Fig. 2 is a detail front view of the gate-latch. Fig. 3 is a detail section in line 3 of Fig. 2. Fig. at is a vertical cross-section in line i l of Fig. Fig. 5 is a horizontal section in line 5 5 of Fig 2. Fig. 6 is a side elevation of an adjusting device for taking up the slack in certain portions of the device. Fig. 7 is a detail perspective view of a guide. Fig. 8 is a top plan of a bell-crank lever used in the operation of the gate, and 9 is a detail perspective of a loop at the end of one of the operatingwires.

Looking at Fig. 1 the gate is seen at A,hinged upon a suitable supporting-post B and latched to the post 6. A post D is located in a line at rightangles to the gate-line. A second post D is located in a line with the posts B D and at a distance from the post 13 approximately equal to the length of the gate A or probably a little longer. The post D is located at such a distance from the post B that a person driving toward the gate from the left may operate the handle E and swing the gate open without its striking the horses. \Vhen driving toward the gate from the opposite direction, the operating-lever E is drawn toward the operator to open the gate, which swings away from him. Thus the post D can be placed nearer the post B than the post D.

The operating-levers are seen at E E and are alike. On the top of the post D are bolted two strips 6 e, (see Fig. 6,) and these strips form bearings for the adjusting screw 6. This screw extends beyond one of the strips 6 and is bent to form a crank c and upon the adjusting-screw is a block a having a pin e upon which the operating-lever E is pivoted. This forms a swivel connection between the operating-lever E and the post D, so that the lever may be swung in a plane at right angles to the ad justin g-screw and also parallel therewith.

Upon the top of the post B is secured a bracket f, (see Figs. 1 and 8,) having a pinf, upon which is pivoted a bell-crank lever F F. The short arm F is connected with the upper end of the operating-lever E by a wire F and to the lever E by a wire F at a point below the pivot 6 equal to the distance from the short end of the operating-lever to the pivot. A wire E connects the short end of the lever E with the lever E at a point below the pivot equal to the distance from the pivot to the short end of the lever. This wire E causes both the operating lovers to be oscillated when one of them is operated. I have shown an arm f extending at right angles to the arm F of the bell-crank lever, which is intended to support the wire F and prevent the same from falling below the bell-crank lever, as that would seriously impair the successful opening and closing of the gate.

The latch is shown at G, and is best seen in Figs. 2, 3, 4c, and 5. Upon the post G is secured a forked bracket g, in which is pivoted a weighted latch g. A pin is secured in the forked portion of the bracket and the latch is provided with a slot adapted to swing about the pin The pin forms a stop for the latch and the slot limits the oscillation of the same. Upon the gate is secured a bracket g provided with a stud 9 upon which is journaled a roller G, and this roller is prevented from sliding off the stud, preferably, by means of a split pin. I have shown the bracket 9 as vertically adjustable, and, as shown, this adjustment is made by securing a plate to the gate, which has overhanging edges formingtongues (see Fig. 5,) adapted to fit in suitable grooves upon the edges of the bracket The upper end of the plate g is bent at right angles thereto to form a horizontal portion g", in which is seated an adjusting-screw 9 which passes through the bracket 9 The bracket is slipped upon the tongues g of the plate g from the bottom and then an end piece g is secured to the plate g said end piece serving to assist in guiding the'lower portion of the adjustingsorew. The plate 9 is secured to the gate in any suitable manner, preferably by means of screws, and one of the screws which secures the plate to the gate may serve in holding the piece 9 to the plate. I have shown a jam-nut g, which prevents the screw from being lifted up by any cause. To adjust the bracket, the jam-nut g is loosened and the adjusting-screw rotated, so as to raise or lower the bracket-g to the proper position and the jam-nut again adjusted to place.

Upon the bracket g is a stud g upon which is pivoted an unlocking-lever Giwhich is adapted to swing the latch g downward and allow the roller G to freely pass by when either of the operating-levers is first swung to open the gate. A finger g is provided upon the bracket g which extends across the lever and down the outer edge thereof (see Fig. 2) and assists in guiding the lever in a vertical plane. \Vhen the lever is swung in the direction indicated by the arrow thereon, it depresses the latch g and allows the roller to pass over the same.

The means for swinging the unlockingle ver G is best seen in Figs. 1 and 7. A rod 11 is hooked into the end of the long arm F of the bell-crank lever and through a slot 71 in a bracket II, secured upon the gate. A smaller rod H is hooked into the downturned endh of the rod H and fastened to the end of the unlocking-lever G I have shown a turnbuckle h upon the rod H for varying the length of the same upon diiterent-sized gates; also, a weight 7L2, hung from the end G of the unlocking-lever, which assists in holding the end G in a raised position, so that the latch g may stand in the path of the roller G and prevent the opening of the gate, except when the operating-levers are swung. I have shown the weight h as a wrench adapted to adjust the lag-screws upon the different portions of the gate; but it is obvious that any sort of weight may be used.

WVhen the gate is closed, the roller G, besides forming the lock for the gate, rests upon the bracket 9 and thus supports the free end of the gate. This roller is made long enough so that it will always rest upon the bracket g when the gate is closed, should the gate expand or contract from the effects of the weather.

A device for holdin g the gate open is shown at I J, (see Fig. 1,) and the port-ion of the latch upon the gate is similar to the adj usting-bracket g and roller G, except that the unlocking-lev er G is removed therefrom. A post D is placed in a line with the posts B D in such a position that the latch hereinafter described, which is supported by said post will strike the roller I of the locking device and hold the gate open. The latch J is similar to the latch G, and an unlocking-lever j is pivoted to the post D and has a pin j,

pivot.

lying underneath the weighted portion of the latch. A wire j extends from the unlockinglever j to the wire F which is considerably slack. I have shown a turnbuckle upon the wire 7' to adjust said wire if it is desired to lengthen or shorten the same to reach the wire F I have shown a beam D resting upon the post D and connecting the posts B D; also, a similar beam connecting the posts 13 D for bracing the same. Posts cZ may be interposed between the posts D D B D to support the beam.

Fig. 9 shows a means for forming a loop at the end of the wireswhere they are secured A washer 7;, having two holes k is slipped upon the end of the wire through the hole 70, the wire then passed through the hole in the part with which it is desired to connect it and then back through the hole k where it is given a bend to prevent its withdrawal. This forms a very simple and substantial loop and is adapted for use upon any of the wires where they are connected with the operating portions ofthe device.

The operation of the device is as follows: WVhen approaching the gate from the left, as seen in Fig. 1, the operating-leverE is swung in the direction indicated by the arrow thereon, thus drawing the wire E with it and cansing the lever E" to swing in the direction in dicated by the arrow thereon. This draws the wire F in the direction of the arrow thereon,.rotating the bell-crank lever F F upon its At the beginning of the stroke the rod l-I slides in the slot h and raises the weighted end of the unlocking-lever through the rod H thus depressing the latch g. \Vhen the hook 71 strikes the end of the slot h, it draws the gate around until the roller I engages with the latch J, which holdsit open. The Operator now passes through the opening and grasps the operating-lever E, which has been swung toward the right by the opening of the gate, and draws it toward him, thus reversing the directions of the movements of the wires, first taking up the slack in the wire F "and lifting the unlocking-lever j, which raises the latch J, thus releasing the rollerI, then swinging the bell-crank lever in the opposite direction to that when swung in opening the gate and pushing the gate to a closed position throhgh the rod H, when the roller G will pass over the latch g and become locked.

The construction shown and described is extremely simple and effective and is capable of being attached to any gate.
