GATE-LATCH.-

To all whom it may concern:

Be it known that I, FRANK SLATTERY, a citizen of the United States, residing at Perry, in the county of Dallas and State of Iowa, have invented a certain new and useful Gate-Latch, of which the following is a specification.

The object of my invention is to provide a gate latch of simple, durable and inexpensive construction which may be readily 0perated from either side of the gate.

A further object is to provide a gate latch having a member which tends at all times to automatically turn to position for lock ing the gate when closed.

A further object is to provide a gate latch which, when released, will permit a gate to swing in either direction.

A further object is to provide a gate latch which is adapted for securing the gate, both at the lower and the upper side of its free end, thereby preventing small animals from pushing the gate partially open at its lower side.

A further object is to provide a gate latch comprising members which automatically engage when the gate is moved to its closed position.

A further object is to provide a latch member designed to be detachably secured to a post, and so constructed and secured to the post that it may be adjusted vertically thereon to allow for sagging of the gate or other circumstances.

A further object is to provide a gate latch comprised of few and simple parts which are inexpensive in construction and not likely to get out of order, and easily repaired or replaced.

My invention consists in certain details, in the construction, arrangement and com- 1 bination of the various parts of the device, whereby the objects contemplated are at tained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which:

Figure 1 shows a side elevation of the free end of a gate equipped with my improved latch. Fig. 2 shows a vertical, transverse, sectional View through the free end of a gate equipped with my latch taken on the line 22 of Fig. 1. Fig. 3 shows a horizontal, sectional view on the line 33 of Fig. 1. Fig. 1 shows a front view of part of a post equipped with my latch and latch holding plate, partly in section.

Specification of Letters Patent.

Application filed June 17, 1912.

Serial No. 704,438.

Referring to the accompanying drawings, I have used the reference numeral 10 to indicate an upright member at the free end of an ordinary hinged or swinging gate. The gate fabric may be of any desired material. As shown in the drawings the upright end member 10 and upper and lower horizontal members 11 and 12 are made of pipe. Adjacent to the free end of the gate in its closed position is a post 13.

My improved gate latch comprises a memher or members designed to be secured to a post and a member designed to be secured to the gate proper. The members upon the post and gate may be interchanged but I preferably place them as herein described.

On opposite sides of the post 13,1 provide detachable and adjustable plates l-il, each of which is provided at suitable points with series of notches 15. The plates 14: are secured to the sides of the post 13 by means of bolts 16 which are received in the notches 15 and extend through the post. The heads of the bolts 16 engage the plates 14 on one side of the post and the other ends of the bolts are screw threaded and received in nuts 17 which are provided with handles 18.

As will readily be seen the plates 14. may be adjusted vertically on the post 13 by loosening the nuts 17 and raising and lowering the plates and placing them in position with the bolts 16 received in higher or lower notches than before.

At suitable points upon the plates 141 are secured catch members, each comprising a body which may be of any suitable form but which is shown in the drawing as a plate 19 secured to the plate 141 and provided with a right angled extension 20 slightly tapering in form from the plate 141 to its outer end. Pivoted to the outer end of the extension 20 is a pawl 21 which normally extends downwardly and toward the post 13 on each side thereof. Formed on the free end of each pawl 21 is a short arm 22 normally extending upwardly and toward the post 13 and designed when the pawl 21 is in its normal position to engage the plate 19 and limit the downward movement of said pawl 21. Lugs 23 are formed on the upper edges of the extensions 20 in position to engage the arms 22 when the pawls 21 are moved upwardly and to limit the upward movement of said pawls 21. The lugs 23 are so located on the extensions 20 as to permit the upward .movement of the pawl 21 to a point where jacent to the'post 18 whenthe pawl is per mitted-to drop to its normal position;

Beloweach of the pawls 21 I provide'lugs 21 on the plates 14, having their upper edges inclined from their free ends upwardlyand' toward the plates 14 to cause the bar26 and extension 29, hereinafter described, tomove to proper position inaen gagement with the pawls 21.

On the free end of the gate, I'provide a lever 24 which is pivoted at its lower end' to a point near the lower side of the gate to swing in a vertical plane adj acent-to the gate member 11; The form of the lever 24- may be-variedr1n the drawing, I have shown it as a bar. l v

Near the upper end of the lever 24, I

pivota'lly secure to the horizontal member 12.

of. theflgate a short arm 25' which normally hangs downwardly'and is capable of pivotal movement in a vertical plane. At its lower end the arm 25' is-pivoted' t0 the 'rear end of an approximately horizontal bar 26, which extends forwardlyto position to be engagediby the pawl 21 when the gate is closed as shown in Fig. 1. A short arm 2:? ispivoted to the member. 11 of the gate and to the bar 26 parallel to and in" front of the arm 25. On the bar'26 is a staple" 27 i through which is extended the lever 24. The staple 27 is of sufficient size to allow considerable play ofthe' lever 24. On the member 11 is a guide loop 2 to limit the lateral movement of the lever arm 24 with reference to'the gate. In the upper surface of the loop- 27 is a notch 27*. The lever 24 extends above the gate to po sition where may be easily grasped by a person desiring to open or close the gate. On the'upper end of the lever 24 is pivoted a pawl 24 which, when the lever 24 is in position for holding the gate closed, drops into the notch 27 In its normal position the lever 24 is inclined upwardly and forwardly, as shown in Fig. 1.

When the lever 24 is moved rearwardly ther toward vertical position it is engaged by said loop 27. The loop 27 thus serves to limit the rearward movement of the-lever 26. 'The loop 2'?" is so placed that the lever cannot move 'rearwardly to vertical position, and the weight of the said lever 24 and the bar 26"and' the tendency of the arms 25 and 25 to drop to vertical position always tend to draw the lever 24 toward the free end of the gate.

Pivotally secured to the lever 24' near the lower endthereof is a bar 28 normally extending between the upright downwardly and forwardly and provided with anapproximatelyhorizontal forward extension 29 which, whenthe gate is closed; stands in position to be' engagedI'byone of the} pawls 21'. I

The bar26-and-theextension 29 are slidmember10'.- To lessenthe'friction of the extension 29- in the slot in the upright mem-i In practical operation, when a" gate equippediwith my improved latch is closed, the bar 26 and extension'29' are engaged by the pawls 21*and are held between-"said pawls and theplates'14 above the lugs 21?. The lever 24 is inclinedupwardly and forwardly from its pivotal point-at its lower end,- as shown in 'Fig. 1. WVhen it is dethe lever24 and movesthe said lever and the'bar26 andrextension 29"away from the free end of the gate, or rearwardly. The bar 26 and extension 29 arewithd-rawn from their position between thepawls 21 and the the lever 24 toward vertical position is'continued the loop 27'" engages: the lever 24 lever 24 past deadcenter. The gate can then be swung in either direction from the post, 13

for any other reason to adjustthe pawls21. vertically, the plates 14 may be *adjusted i'n the manner hereinbefore set forth.

i It will ber'eadily seen that my gate latch has numerous" advantages. It is of extremely simple and inexpensive construction. It can be made of'materials which are easily available. It is compose'doffew and simple parts which are easy to repair and replace. After the gate is" opened'ythe .movement' of the partstowar'd position for; latching thewhen closed.

The latch members on the post 13 may be readily adjusted to allow for sagging of the gate.
