GATE-LATCH.

Application filed April 18, 1917.

To all whom it may concern Be it known that we, ADnLLn STILLINGS and Tnoims W. CARL, citizens of the United States, residing at (1) Spanaway, (2) Tacoma, in the county of (1) Pierce, (2) Pierce, and State of Nashington, have 1nvented certain new and useful Improvements in Gate-Latches; and we do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in gate latches and operating mechanism.

The object of this invention 1s the provision of a gate latch, which 1s adapted to hold a gate closed and is provided with suitable operating means and foot treadles, whereby the gate may be automatically opened by pressing one of the foottreadles.

Another object of this invention is to provide the automatic opening and closing device for gates, which may be operated by foot treadles swinging the gate open n either direction and which will automatically reset itself for another operation upon the closing of the gate.

A further object of this invention is the provision of a swinging gate which is hingedly connected by self closing hmges and is adapted to be held closed by a pair of operating members, which constitute latches and opening members, and these latches are pivot-ally secured to a supportingplat-e and are connected to foot treadles and links so that the gate may be automatically swung open in either direction and will automati-v cally close itself and reset the operating members for operation of the gate in either direction.

A still further object of this invention is the provision of a gate provided with selfclosing hinges which may be swung open in either direction and has cooperating therewith, a pair of operating members, which are rotatably mounted on a shaft which is rigidly secured to a supporting plate, asecond supporting plate located below the first named supporting plate and has pivotally secured thereto, a pair of foot vtreadles, links connecting each of the foot treadles with one of the operating members, whereby upon operation of either of the foot treadles one of the operating members will be operated moving the gate in either direction desired and the hinges automatically Specification of Letters Patent.

closing the gate and resetting the operating members for another operation.

A still further object of this invention is the provision of a gate latch of this character, which will be simple, durable and efiicient, and which may be manufactured and sold at a comparatively low cost.

lVith these and other objects in view, the invention consists of the novel combination and arrangement of parts hereinafter more fully described and set forth in the claims hereto appended.

In the drawings:

Figure 1 is a front elevation illustrating my gate latch applied to a gate and made in accordance with this invention,

Fig. 2 is a transverse sectional view illustrating the operating mechanism with the gate removed, I

Fig. 3 is a horizontal sectional view illustrating a fragment of the gate showing the manner in which the gate is held in closed position,

Fig. 4 is a perspective view of the treadle supporting plate,

Fig. 5 is a horizontal sectional view taken on the line 5-5 of Fig. 2,

Fig. 6 is a perspective view of one of the foot treadles,

Fig. 7 is a perspective view of one of the operating members,

Fig. 8 is a perspective view of the operating members supporting plate.

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

Referring more particularly to the drawings, the numeral 1 designates a pair of substantially rectangular posts arranged at a spaced distance apart and they may be embedded in the ground and supported by suitable braces 2. The posts as here shown are substantially rectangular, itxbeing understood that any other desired shape may be used as the invention does not rely on the construction of the posts.

A gate 3 is hingedly connected to the inner face of one of the posts 1 as at a and these hinges are of the self closing type of any construction, thus the gate will be automatically returned to a closed position at all times.

Our improved gate latch is applied to the inner face of one of the posts 1 and to the post that is remote from the post to which the gate is hinged as shown in Fig. 1.

The latch comprises in its construction, a supporting plate 5, which is substantially rectangular and is constructed of any suitable material, suitable for the purpose and it has its medial port-ion strucl; up to provide the laterally extending centrally arranged aced barrels 6, which barrels are defined by slitting the plate or providing the plate with a plurality of spaced vertical slits, and these portions are struclt up to provide the barrels 6 as illustrated in Figs. 1, 3 and The plate or the posts 7, such as screvvs, nails or the like and secured thereto adjacent the upper end. hereof, clearly shovvn in Figs. 1 and 2 of the drawings.

shaft 8 is arranged transversely in the barrels t and rigidly secured therein and is adapted to h ve rotatably mounted thereon, the operating members, which are designated in their entirety by the numeral 9.

The operating members comprise .in their construction, the bearing collars 10 and the construction of both is identical, thus providing companion or duplicate operating members, description of one is thought to be sutlicient for both.

The bearing collar 10 has formed on one end the ally projecting extension 11, which is arranged substantially atright angles to the collar 10, and each of the collars 30 are rotatably mounted on theshaft S and between the barrels (has siovvn in Fig. 3, and by the positioning of the bearing collars on the shaft 8, they are'spaced apart by the intermediate barrel 6 of the plate 5 and the extensions 11 ontheouter end of each of the bearing collars 10 are directed imvardly, and they prevent the bearing collars from being interchangeable.

'llr extension has the tapered outer end 12, which is curved upwardly and inwardly to provide a convex outer surface and constitut s a latch member for holding the gate closed and al o the gate Will strike the convex surface of this extension, raise the device upwardly and permit thega'ie to automatically close itself. The extension 11 has the dovvnu'ardly and outwardly inclined surface 1-3 and has its lower-edge curved invvardly' as at ll to provide the angular extension 16, which has its forward end bent upwardly and outwardl as at 17 to constitute gate opening member. The portion 1% is provided vvith the openings 18, in which pivot-ally secured one end of the operating rod 19, the purpose of which will be hereinafter more fully described.

The construct-ion of each of the bearing collars 10 is so arranged as to provide the latch holding member, operating memhers and a gate opening meinbe providing meansvvhereby the gate may be automati- 5 is secured to the inner face 1 bv suitable fastening means cally closed and automatically opened, Which Will be hereinafter more fully described.

1L rectangular supporting plate 20 is rigs idly secured by suitable fasteners 21 to the inner face of the posts 1 and is located belorv the supporting plate 5 adjacent the lovcer end of the post thereof.

A pair of substantially ill-shaped straps 22 have the ends of their legs bent angularly to provide attaching members 23, which are "dly secured by suitable fastening means such as rivets, screvvs orthe like to the face of the plate 20, their Web portions in vertical alineinent and ata. saaced all C;

i which are therein, the foot tread adapted to have pivotally secured es Lo.

of the treadles are provided intermediate t endswith the openings 30 and are 1 votally secured to the inner face of the medial port1ons of the straps and the inare illZtPt to overlie one another in Fig. 2, and each of the inner ones of the treadles 26areprorided iviththe openings 31, which have pivotally secured thereto, the loiver free ends of the links 19, thus the treadles 26 will be normally held in t horizontal position, as shovvn in 2. l hen the treadles are in 'ahorizontal position, as illustrated, the tapered sions 12 constituting the latches of-the hearing collars 10 will also be in a substantiallv horizontal plane, thus the gate will be held o a swing in either direction. The 3 provided with a vertical rib 32, hichlias cured thereon, the metal Wear plate which wear plate is adapted to be nged betweenthe latch members 12 of each of the bearing collars 10 when the are in substantially horizontal plane to hold the against'movement in either direction.

ll hen it is desired to operate the gate, for movement in either direction, it is only necessary to place the foot upon one of the pertions 28 of either of the treadles and press the same downwardly and which operation Will raise its respective operating member 9 upwardly, thus forcing the extension or gate opening memberl? into engagement with the the rib 33, throwing the gate open in the direetion that the person is walking, and upon the person passing through the gate, the latch will drop back into its original position and after the person has passed through the gate, the gate will automati cally close and the rib will strike the con vex portion of the extension 12, raising the operating member to permit the gate to be arranged between each of the extensions and the device is reset and ready for operating or movement in either direction.

It is to be understood that when looking at Fig. 2 at the inner end of the lever 26, it appears on the left side of the figure and is connected to the operating member, which appears on the right hand side of the figure and is connected thereto by the link 19, thus it can be seen that by pressing on the ortion 28 of the lever or treadle 26 on the left hand side of Fig. 2 that it will raise the operating member 10 that appears on the right hand side of the Fig. 2, this will force the extension or gate opening member 17 into engagement with the left side of the rib 33 and swing the gate outwardly to the right and in the direction the person is walking.

It being understood that when the other treadle on the left hand side of Fig. 2 is operated that the operation will be repeated in the reverse manner.

It can be also understood that the extension 17 or gate opening member 17 of one of the operating members 10 is inclined in a plane below the other member 17 so as to permit them to pass one another during their operation.
