LOCK-STRIKE.

SPECIFICATION forming part of Letters Patent No. 475,000, dated May 17, 1892. Application filed June 23, 1891. Serial No. 397,204. (No model.)

To all whom, it may concern,.-

Be it known that I, FRED. E. RANNEY, of

Belding, in the county of Ionia and State ofA Michigan, have invented certain new and useful Improvements in Locks and Latches; and I do hereby declare that the following is afull, clear, and exact description thereof, reference being had to the accompanying drawings, and

to the letters of reference marked thereon,v

which form a part of this specification.

This invention relates to latches and locks, and more particularly to that class designed for use in connection with refrigerator-doors and other doors which it is desirable to have vclose tightly and with certainty.

The object of my invention is to provide means for readily adjusting the parts of the lock or latch relatively to each other, so as to compensatefor any shrinking or swelling of the parts to which they are attached; and to this end it consists in the several features of novelty which I will now proceed to describe, and will then more particularly point out in the claims.

In the accompanying drawings, Figure l is a front elevation of a lock emboclying,r my invention. Fig. 2 is a side elevation of the keeper and its casing, lthe catch or latch proper being shown in section. Fig. 3 is a similar view of the casing of the keeper detached. Fig. 4 is an elevation of one side of the keeper proper detached. Fig. 5 is a similar view of the opposite side thereof. Fig. 6 is a bottom plan section taken on the line 6 6 of Fig. l and looking in the direction of the arrows. Fig. 7 is a detail rear elevation of a portion of the keeper.

In the drawings, A represents a portion of the door or door-stile, and A a portion of the door casing or stile of the door-casing. Upon the doorA is mounted a lock B, the detailedV construction of which is immaterial, the form shown being awell-known one, provided with an upwardly-yielding spring-depressed catch or latch B. This latch is operated by means of a knob B2 and is provided with a curved or inclined rea-r striking-face b and a plane front locking-face b. The lock is also provided with a key-hole b2 to receive a key B3, by means of which the catch or latch B may be locked in the position shown.

The keeper C is mounted on' the door-casing stile A and consists ofthe usual casing C and an adjust-able keeper proper D, which latter is mounted on suitable ways in the casing and is held and adjust-ed therein by means of a screw E. The detailed construction which I prefer and have devised for this purpose is that shown in the drawings, in which the casing C is provided with parallel guideplates c and c and a guide-rib c2, forming the ways betweenV which the keeper proper slides. The lower guide-plate c' is cut away at the rear, as shown at c3 in Fig. 6, leaving a short rearwardly-projecting tongue c4, which is an extension of the said guide-plate c. The keeper proper D is composed of a vertical body portion D', having a curved or inclined front striking-face d and a plane rear lockingface d', and of a rearwardly-extendingshank D2, adapted to fit between the guide-plates c c and having a lateral upwardly-extending flange d2 of a height about equal to the thickness of the upper guide-plate c, the edge ot which it covers. At the rear end of the shank D2 there is formed a downward extension D3, adapted to tit in the cut-away space c3, between the tongue c4 and guide-rib c2, being provided with a notch d3 to receive said guiderib. The lower portion of the downward eX- tension D3 is provided with a threaded aperture to receive the adjusting-screw E. This screw passes through an unthreaded aperture in the front wall of the casing C and is providedon the outer side of said wall with the usual slotted head e or other suitable means by whichit may be rotated. Inside of said wall there is mounted on said screw a washer E', held in position by a pin e', said washer serving, in conjunction with the head e, to prevent longitudinal movement of the screw while leaving it free to be revolved.

In the case of refrigerator and other doors it frequently happens, owing'to the swelling or shrinking of the parts, that the door either cannot be entirely closed` sticking before it latches, or in closing passes beyond the normal limit of its motion, hanging loosely and free to vibrate between its seat and the point where the locking-faces of the latch and keeper are in contact. Both of these conditions are manifestly undesirable. The ob- IOO.

jections attendant thereon may be obviated bythe use ot' the construction just described, since it will' be at once seen that the keeper proper D may be readily adjusted in or out through the medium of the screw E, so as to assume such a position that at the limit of the doors 'motion 'the catch orlatch B- thereof.

will just pass over and downwardubehind the body D of the keeper and hold the door firmly and tightly closed. It Will be noted that the keeper is adjustable in the directionvot motion of the door and that the adjusting-screw is accessible at the exterior ofthe casing when the door is closed'and the latch `in*engagement with the keeper proper. By reason of this the door may be closed to the proper extent and the keeper proper then adjusted to its proper position relatively -tothelatcln saidlatchthus ,y

acting-'as a gage to determine `the position ofthe keeper proper. 'adjustmentis necessary to obtain the desired end, and this range is inthe construction.

shown limited i-n one direction bythe contact of-"the rear face d of the body D with the front edge of the upper guide-plate c, and in the other direction bythe contact of tlie.front face-of the extension. D3 with the rear edge of 5 the lower guide-plate cf, Within the cut-away i Onlya small range of t it may obviously be used in connection with other formsjotl locks and latches.l

What I claim is--,

l. The hereinbefore-described keeper for locks or latches, comprising a casing, a keeper proper movable in said casing in the direction of motionof the door, and an adjusting device accessible at theexterior of the casing when the latch is in engagement With the said keeper, said adjusting device extending into the casing and positively engaging the keeper proper to adjust the same in either direction, substantially as and lfor the purpose specified.

2. The llifereinbefore-described keeper for locks or latches, comprising acasing provided With guideways extending in the direction of the motion of the door, a keeper proper mounted on -said casing and adapted toslide in said guidewaysfsaid keeper ,havingstops to limit its movement in each direction,.and anadj usting-screw mounted to revolvein the casing and .engaging the keeper yIgiropeiysubstantially as described.

3. Thecombination, Withia Acasing having guideways c c', the .latter cut away at c3 to form a tongue c4, .of a keeper proper Dlhav ing ashank D2 to tit between, --the Ways c c', Aan upwardly.-extending body D at the Afront endot said shank anda downward extension D3 at the `rear end 'thei'eof,` and an adjusting-screw mounted to revolvein the c-a'sf ing and engaging a threaded aperture in the said downward extension Dsubstantiallyas described. ,f 1

In testimony that I claim the foregoing as myinvention I affix my signature in presence ot' tWoWitn-esses. l
