Specification of Letters Patent.

Patented Sept. 30, 1913.

Application filed March 18, 1913 Serial No. 755,203.

To all whom it may concern .1

Be it known that I, THEODORE L. J HN son, a citizen of the United States, residing at Emmetsburg, in the county of Palo Alto, State of Iowa, have invented certain new and useful Improvements in Gate Latches and Locks, and I do hereby declare the following to be a full, clear, and exact descrlption of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. g

This invention relates to improvements in gate latches and locks.

One object of the invention is to provlde a simple latch operable from opposite sides of the gate.

Another object is to provide a double latch device movable by a single operating mechanism from either side of the gate, each bolt of said double latch device sliding independently of the other. 0

Another Object resides in the provislon of simple means for locking the latches 1n latching position. 7

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawings.

In the drawings: Figure 1 is an elevation of the latched portion of a gate showing my invention, Fig. 2 is a similar view showlng one side of the casing removed, Fig. '3 is a horizontal sectional view on the line 33 of Fig. 2, Fig. 4 is a vertical section on the line 1-4 of Fig. 2, Fig. 5 is an end elevation of the latch, and Fig. 6 is an elevation of the keeper mounted on the post.

Referring particularly to-the accompanying drawings, 10 represents the latch end portion of the gate. 7

The mechanism on one side of the gate being identical in construction with that on the other side, the description of one is therefore thought sufficient for both.

On the side of the gate is mounted a guiding sleeve 11 which has slidably mounted therein a latch bolt 12, the inner vertical edge of which is straight as indicated at 13, while the opposite side at the projecting end is curved or rounded as indicated at 14, this rounded portion being adapted to engage against the keeper member 15 mounted on the post 16. On the upperside of the sleeve 11 near the inner end thereof is formed an elongated slot 17 through which projects the hook member 18 carried by the rear portion of the bolt 12. A similar member 19 is .mounted on the side at the outer end of the sleeve 11, and secured at its opposite ends to the hooks 18 and 19 is a coil spring 20, this spring normally holding the curved end of the bolt projected a short distance from the end of the sleeve. In the lower side of the sleeve 11 is formed an elongated slot 21, and carried by the lower side of the bolt 12 and projecting through the slot 21 is an ear 22, this ear being adapted to be engaged by an ear 23 carried by a sleeve 24 keyed to a shaft 25, said shaft extending through the gate, below the sleeve 11 and projects from opposite sides thereof. The opposite ends of the shaft 25 are provided with crank handles 26 by means of which the shaft may be rotated, to bring the ears 23 into engagement with the ears 22 to move the bolts 12 backwardly through the sleeve 11, and against the tension of the spring 20. It will thus be seen that when either of the handles 26 is rotated, both of the ears 23 engage the cars 22 and move both the bolts 12 rearwardly simultaneously.

Secured on each side of the gate, and covering the sleeve 11, and the shaft 25, are the cover plates 27, these plates being provided with openings 28 to permit the ends of the shaft to project therefrom. Extending through the door at the rear of the bolts 12 is a shaft 29, on each end of which is carried a sleeve 30, the sleeves each being provided with a radial finger or lug 31. This shaft 29 projects through the openings 32 in the opposite cover plates and is formed with square terminals which are adapted to be engaged in a square socket of a key 83. The rear ends of the sleeves 11 are open and when the shaft 29 is turned, by'means of the key, these fingers or lugs carried thereby are turned into engagement with the rear ends of the bolts to prevent retraction of the bolts.- Thus the bolts may be locked.

Attention is particularly called to the fact that when the gate is moved to closed position, the innermost of the bolts 12, or the one in advance will be forced inwardly independently of the other bolt by the engagement of the rounded end against the keeper 15, the other bolt engaging against the keeper with its flat side and preventing the gate swinging beyond the closed position.

In a latch of this character, the gate may be opened in either'direction, the action being the same.

l/Vhat is claimed is:

1. A gate latch comprising independently repressible spring-pressed bolts carried by. the gate, a rotatable element carried by the gate, and means carried by the bolt engaged;

by said element 'during'the rotation thereof for effecting the simultaneous zretraction ofi the bolts.

2. A gate latchcomprising guides mount-1 ed on opposite sidesofthe gate, independently movable bolts slidably mounted in the guides, springs for holding the bolts in projected, position, lugscarried by the bolts, a

shaft rotatably mounted in the gate, and

lugs carried by the shaft for engagement with the bolt carried lugsito'iretract the bolts simultaneously.

3. A gate latch comprising independently slidable spring-pressed -bolts mounted on the gate, means operable from either side of the gate for retracting the'boltssimultaneously,

a keeper mounted for engagement by the "bolts and confinement therebetween, and means:operable-lirom either side of the gate 4 -for locking the bolts against'movement."
