Specification of Letters Patent.

Patented Jan. 11, 1916.

Application ledvIl/arch 20, 1915. Serial No. 15,758.

To all whom it' may concern:

Be it known that I, FRANK H. BoGDA, a

citizen of the United States, and resident of Burnett, in the county of Dodge and State of Wisconsin, have invented new and useful Improvements in Gate-Latches,ofwhich the following is a description, reference being `had to the accompanying drawings, which are a part ot' this specification.

The invention relates to gate latches.

The invention designs more particularly to provide a latch for gates for cattle pens.

The invention further designs to provide a gate-latch for a gate which may be swung eitherinwardly oroutwardly and which will'au'tomatica'lly lock itself in its intermediate position.

The invention further designs toprovide a self-locking gate-latch comprising a plurality of locking bolts for engaging the lixed portion of the fence adjacent the gate, and'means for simultaneously moving said bolts out of locking engagement to permit opening of the gate in either direction.

rEhe invention further designs to provide a new and improved form of gate latch.

The invention consists in the several teatures hereinafter set forth and more particularly delined by claim at the conclusion hereof. j

In the drawings, Figure 1 is a view of the device embodying the invention, parts being broken awav and parts being shown in section; Fig. 2 is a section taken on line 2-2 of Fig. 1; Fig. 3 is a section taken on line 3-3 of Fig. 1.

The latch is shown applied to a portion of a gate which is adapted to be swingingly mounted upon one of the fence standards (not shown), and comprises means for locking the gate to another standard 5 of the fence and means for releasing said locking means.

The latch comprises a plurality of hori- Zontally extending members 6 which are provided with apertured extensions 7 for receiving a vertically disposed member 8 of the gate. lThe members 6 are also provided with apertured extensions 9 adjacent one of their ends which are mounted upon a standard 4 of the gate to secure them thereto. The latch further consists of bolts 10 which are slidably mounted in the bores 11 of the members 6, means connected to the standard 5 for receiving the bolts 10, and

means 'for automatically moving said bolts t0 locking position.

The means connected to the standard 5 for receiving the bolts 10 comprises channeled members 12 having apertures 13 therein for fitting said members upon the standard 5 and another standard 6 of the fence adjacent thereto. Extensions 111 are provided on one of the ends of the members 12 and each of these extensions has a locking pocket 15 therein and beveled sides 16 and 17 adjacent either side of said pocket. The pockets 15 are adapted to receive the ends 18 of the bolts 10 and the ends of the members 6 extend outwardly to a position adjacent said pockets.

The means :for automatically moving each of the bolts l0 to locking position comprises a spring`20 surrounding a reduced portion 21 of the bolt which portion 21 is slidably mounted within an raperture 22 in said member 6,` the said spring being interposed between the end of the member 6 and the shouldered portion 23 of said bolt. Each of the springs 20 normally act to move the bolts outwardly so that when the gate is swung in either direction the bolts 10 engaging either the beveled sides 16 or 17 will be moved inwardly against the action of the springs 20, but when they come in line with the pockets 15 the springs 20 will move the bolts outwardly and cause their ends 18 to seat within the pockets. The means for releasing the bolts simultaneously from locking engagement with the pockets comprises linkage operatively connected to said locking bolts 10 and means for simultaneously operating said linkage.

The linkage connected to each of the bolts 10 comprises in each instance a bell crank lever 24 pivctally secured by a pin 25 to a flange 26 on the member 6 and having a hooked end 27 engaging in a horizontally extending vertically disposed slot 28 in the bolt 10, and in a slot 28 in the member 6 and have an end 29 pivotally secured to a link 30.

The means for simultaneously operating the linkage above described comprises a grip handle 8l pivotally secured intermediate its bottom portion by a bolt 32 to a collar 33 on the standard 4 and to either end of which the ends 341 of the links 30 are pvotally secured.

To release the bolts 10 from locking en- Ivi gagement with the pockets 15 all that is necessary is to rotate the handle 3l in either direction which action will causerthe links 30 to move inwardly and the hooked ends 27 of the bell crank levers 24 to move inwardly against the locking bolts l0 adjacent the slots 28 and against the action of the springs 20 to move said bolts inwardly and out of the pockets l5.

.In order that the action of the gate may be self-closing without interference 'from the bell crank levers 24, I form the slots 28 in the locking bolts of suliicient length to provide a lost motion connection between the bolts l0 and the hooked end27 of said levers so that the bolts may be moved inwardly when engaging the beveled sides 16 or 17 without interference from said levers.

The operation of the device having been previously described in connection with the description of the parts of the device furthery detail explanation is deemed unnecessary.

' The invention thus exemplifies a gatelatch' for a gate which may be Vswung in either direction and automatically locked in mid-position and the locking means of which may be simultaneously released by a single operation.

The invention is not to be restricted to the details of construction herein set forth, but may be varied so as to be within the scope of the appended claim.

Vhat I claim as my invention is A gate latch comprising horizontally disposed members mounted on the gate and having longitudinally extending bores and slots therein, a pair of locking bolts slidably mounted within said bores and having slots therein, springs disposed within the bores to normally act upon said bolts, locking pocket members on the adjacent fence standard to receive said bolts, and means for unlocking said gate comprising bell-crank levers pivotally connected to said members and having one of their ends slidably mounted in the slots in said members and in the locking bolts, a handle rotatably mounted upon said gate, and links connecting said levers with said handle whereby the handle may be turned in either direction to unlock the gate.

In testimony whereof, I affix my signature, in presence of two witnesses.

...FRANK n., Bosnia.
