To a/ZZ whom it may concern:

Be it known that I, GEORGE WARNER, a citizen of the United States, and a resident of Dearb orn,Lewis and Clarkev county, Montana,

and useful- Imrovements inGate-Latches, of which the folowing is a specification.

The present invention relates to a latch mechanism more especially adapted to gates or doors which open in eit er direction.

The object of the present improvement is to provide a simplle and effective latch mechanism with whic gate from its proper closure position or the swinging of such gate past such proper closure position is prevented in a ready and effectual manner and which involves an automatic means, which is operativel connected with the main latch mechanism or effecting gate; Fig'. 5,

the initial sto page and holding of the gate at such proper c osure position previous to the engagement of the latch mechanism to secure the ate in such closure position, all as will hereinafter more fully appear and be more particularly set forth in the claims. I attain such objects by the construction and arrangementof parts illustrated in the accompanying drawings, in which Figure 1 is a fragmentary elevation of a swinging gate to which the present latch mechanism is applied; Fig. 2, a front elevation of the present improvedlatch with the .front cover vremoved to illustrate the interior latch mechanism and with the latch-bar in section; Fig'. 3, a vertical section of the same on line 3 3, Fig. 2. Fig. 4 is a view similar to Fig. 2, illustrating the parts in the position they would ,take as the latch-bar moves outv upon an opening movement of the a similar view illustrating the osition they would take just at parts in the the latch-bar in a closure the time w 'en movement of the gate swings into position ready to dro .4s

into the central locking-recess of the latch; ig. 6, a fragmentary horizontal section taken on a line intersecting the pit-'otaxis of the triggers 16. Similar numerals of reference indicate like parts in the several views.

Referring to the drawings, 1 represents the frame or casing of the prese latch mechanism, rovided at its lower dwith counterpart inclined guideways 2` 'at`opposite sides Lofthe central latch-receiving recess such guideways being adapted to act planes in raising the free end of the latc either a rebounding of the' 3 as the gate lor door swings into its closure osition.

ble of a limited rising and the The latch-bar 3 may be arranged so that it will be capafallin movement the operation of latching an unlatching ate, and while I have shown in Fig. l a

anv usual manner,

han -lever 24 and connecting-link for manually unl atching the bar 3 when the gate is to be opened any other usual provision for manua l y operating such latch-bar can be'used instead when the circumstances so indicate.

With a view to cause the uP sible I face wit latch-bar 3 to ride on the inclined guides 2 as easily as posrovide the same upon its bearinga roller 18.

5 5 are two counterpart vertically-movable bolts or bars arranged to slide in suitable gil chamber ideways within the interior of thezhollow which constitutes the upper and latch-mechanism-containing chamber of the main frame 1, such guideways lbeing preferformed in the upper and lower removable partitions 7 7 for convenience in assemblage of the latch mechanism, as well as in subsequent repair or replacement of parts.

8 8 are two counterpart crossed levers havin a common and central fulcrum and provi ed at their lower ends with liftin -studs havin individual engagement with t e outturne u per ends of vertical bolts or bars 5 At-t ieir upper ends the levers 8 8 are formed with cam-slots 9 for operative engagement with..connecticns intermediate of said levers and thelatch-bar 3, as hereinafter described.

11 is avertically-movable rod or bar guided a vertical guide-recessl 12 at the back of of a forked with camwidened 'form and provide 95 studs 10, having engagement in the cam-slots of the crossed evers 8, heretofore described. Atfits lower end the vertical bar 11 Yis provided with two projectincg ,ranged one above the other an arms 13, arspaced a art a'sufiicient distance to receive between t em the latch-bar 3 in order that a vertical movement may be imp arted to such verticallymovable bar 11 by the latch-bar as said latc bar moves vertically into or out of the latchro 5 igeceiving recess 4. 136 represents two counterpart triggers, which in the construction shown are forme straight pieces, having when at rest averwith their lower end project- Y11o ing into the path of the latch-bar, so as to be moved laterally thereby as such latch-bar ioo l able bolts or bars 5 5 to hold such bolts in tol their elevated condition. In the present improvement the bolts 5, the levers 8, and triggers 16 'will have a symmetrical arran ement at opposite sides ofthe central vertica line of the latch mechanism, as illustrated in the drawings.

In the construction shown in the drawings the removable partitions 7 rest in sockets 19 in the main frame, 'and the pivoted levers 8 8 are provided with counter-balance-weights 20 at their lower ends to counterbalance the weight of the parts connected to the other ends of said levers and an operation of the said levers and their immediately-connected parts by gravity. The fron-t cover portion 21 of the casing that incloses the operating mechanism of the latch is secured in place prefrabl by long bolts 22, which extend entirely t rough the posts 23 to hold the entire latch in position.

The operation of my improved latch is as follows: With the gate in a closure position the latch-bar 3 rests Within therecess 4 and by means of the lower projection 13 has pulled down the bar 11 and through the instrumentality of the crossed levers 8 and cam slots and

studs

9 and 10 has raised the bolts 5 to their elevated position, as shown in Fig. 2, and in which position the projections 15 of the triggers 16 will engage in the notches 14 of said bolts 5 to lock them in such elevated position, such engagementbeing effected by the force of gravity on the part of the triggers. If now the gate be opened, the latchbar 3 moving to the right after being first raised vertically out of the latch-recess 4 andy moving with it the vertically-movable bar 1 1 into its elevated position, the above-described parts will assume the position shown in Fig. 4, the lower end of the right-hand one of the tggers 16 being pushed along by the latchbar 3 until its upper end str1kes the upper end of the left-hand trigger, as shown at 17, when the left-hand bo t 5 will be released from its engagement with said left-hand trigger and drops into the position shown in Fig. 4 and in which position it constitutes a stop for the latch-bolt in a subsequent return movement. As the gate is subsequently swung back into a closure position the latchbar 3 impacts against the left-hand bolt 5 and drops into the latch-recess 4, carrying with it by means of the projections 13 the vertically-movable bar 11, which serves to raise the left-hand bolt 5 again to its elevated position. (Shownin Fig. 2.) Any tendency of the gate to rebound or swin backwardl after the latch-bar 3 strikes the eft-hand bo t 5 is prevented by the disen agement and dropping of the right-hand bo t 5 into position shown in Fig. 5, due to the movement of the right-hand trigger by the latch-bar.

It is obvious that if the present invention be used on a gate which opens in one direction only but one-half of the construction heretofore described will be. necessary, and either halt can be used, depending upon direction in which the gate opens. It is also obvious that other changes of detail may be made Without departing materially from the spirit of the present invention.

Having thus-fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A gate-latch having a pivoted latch-bar adapted to engage by gravity in its engaging recess, in combination with averticall -moving stop-bolt, a trigger mechanism or sai stop-bolt arran ed 1n the path of the latchbar and adapte to be operated by the latchbar in a closing movement of the gate, to release the stop-bolt and allow the same to move downward into a position to prevent a rebound of the gate, substantially as set forth.

2. A gate-latch comprising in combination, a latch-bar, a pair of vertically-movable stop-bolts,locking-triggers for said stop-bolts, a pair of pivoted levers for raising said stopbolts, and means whereby the movement of the latch-bar operates said triggers, substantially as set forth.

3. A gate-latch comprising in combination, a latch-bar, a central recess in the latchframe for receiving said bar, a verticallymovable stop-bolt, a locking-trigger for said stop-bolt, and means whereby the movement of the latch-bar in the central recess of the latch-frame operates said trigger, substantially as set forth.

4. A gate-latch comprising in combination, a latch-bar, a central recess in the latchframe for receiving said bar, a pair of vertically-movable stop-bolts, locking-triggers for said stop-bolts, a pair of pivoted levers for raising said stop-bolts, and means whereby the movement of the latch-bar in the central recess of the latch-frame operates said trigger, substantially as set forth.
