Application .lune 19, 1944, Serial No. 541,077 4 Claims. (C1. 'Z0-100). l carried by the lead post is the bumper support This invention relates to a combination lock and latch structure. The chief object of this invention is to pro member I'I. This post is slotted as at I8 to nest the lock body. Referring to Fig. 6, it will be observed that vide in a single structure a latch which can be locked and which can have associated therewith this member I‘I retains the cushion bumper struc ture I9, and this is adapted to seat in the groove I2a in cushioning post to post contact when the other locking elements for providing additional locks. The chief feature of the invention consists in closure is closed. providing a latching member that is manually movable from a retracted to a projected position, prised of a pair of plates 26 suitably secured in spaced relation by means of spacing members 2l and suitable connectors 22. Also interposed in thehousing is a pair of spaced aligned guides 23 which are in vertical alignment and a pair of guides and stops 24 and 25 which also happen to be vertically aligned and are adjacent the opening I5. A bearing member 25 includes a stem 2l slidable in guide 23. Confronting the lsame and above it is the bearing member 28 having upwardly directed stem 29 slidable in the upper guide 23. C-shaped springs 3B are suitably and when projected, the same is arranged to function as a catch and which furthermore is provided with means for maintaining the catch in the locked position. Other objects and features of the invention will be set forth more fully hereinafter. ' t The full nature of the invention will be under stood from the accompanying drawings and the following description and claims: In the drawings Fig. 1 is a vertical sectional Iview through a portion of a stationary wall pro vided with a catch plate arrangement, a closure that is slidable to and from that wall and a lock structure carried by the latter. . interposed between the spacing members 2i, which serve as spring anchors, and the members y 26 and 26 and will normally constrain these mem bers towards each other. Interposed between these members is a cross head element SI which is apertured as at 32, and herein said aperture is shown square and serves Fig. 2 is a transverse sectional View taken o line 2-2 of Fig. 1 and in the direction of the arrows. Fig. 3 is a vertical sectional view taken on line 3_3 of Fig. 1 and in the direction of the arrows. Fig. 4 is an elevational View taken in the plane 4--4 of Fig. 1 and in the direction of the arrows. Fig. 5 is a view similar to Fig. 1 and is a mod ified form of the invention. Fig. 6 is a sectional View taken in a plane par allel to the plane 2_2 and remote from the lock. In the drawings I0 indicates a channel having the base portion Iûa which is slotted or notched as at II to form a catch retaining portion IIa. Rigid therewith is a centering strip I2 having the vertical groove I 2a therein. This also is aper tured as at I3, see Fig. l, to pass the catch mem . The lock structure includes a housing com as a cam follower as it were for in that aperture is mounted a disc 33 that serves as a cam or eccentric. ' Extending forwardly from the member SI is the bolt portion 311 which is herein shown recessed as at 35 purely for metal reduction purposes, and the ' forward end of said portion 35 terminates in a hook 36 which has a curved nose 35a and a fiat ber. The closure associated with this stationary ele ment or wall arrangement includes a lead post I 4, also channel shaped, and this has its wings = I5 arranged for suitable connection to the olo sure proper. This is the lead post, and it is to be understood that the closure is movable to ward and away from the stationary post I0, and the closure by means hereinafter to be described, 50 can be latched to that stationary post or locked thereto as desired. The lead post Iii is also slot ted as at IB, and the several slots, when the two posts are positioned adjacent each other, are in rearward face 3l which is the catching face. Rigid with the eccentric 33 is the operating shaft and this extends oppcsitely from said eccentric and is rounded at 38a and is squared as at 3th as shown. A sleeve IlI is provided in alignment with the shaft 38. One of these is at each side of the housing and located within the lead post. A cou pling member 42 has a non-circular exterior and a square cross section interior and telescopically receives the squared end 38a of the shaft carrying the eccentric 33. Extending through circular holes 43 in the side portions of the lead post areA the shafts M, also square, and these at their outer ends carry suitable knobs, 45, masking plates 46, etc. , ' ` ' Now rotating either knob will naturally rotate the eccentric, and in that rotationcertain ofthe springs 3i! will extend and others will compress, registration. Interposed between _the posts and 55 the result being that the bearings 26~and 2.8 will . 2,405,240 3 4 simultaneously elevate or lower, and simultane ously therewith the bolt portion 34 will elevate and lower and will also reciprocate transversely of such elevating and lowering movement. Thus it the reciprocatory movement of the bearing members. The bearing member 126 includes the guide stem 12T and the bearing member 128 in cludes the upwardly directed guide stem 129. is by the aforesaid mechanism that the catch can be raised and retracted from the locked position in Fig. 1 for closure opening or can be projected and dropped into locking position as shown in Fig. 1. The plate 46 previously mentioned is extended Herein the upper guide member is recessed as at 160 to clear or accommodate the eccentric 150. Now when the eccentric 15B is locked in the position as shown in Fig. 5, the upper end of the guide stem 129 is engaged by said eccentric so that the lock or bolt member cannot be verti upwardly in the present instance and provided cally reciprocated, and hence, the closure can not be unlocked. When the eccentric 1511 is with apertures 46a. The side portions of the lead post are also apertured at 41" and a cylindrical moved to the dotted line position, the guide stem housing 48 is suitably retained in said aligned openings and mounts within it the barrel of a ' cylindrical lock which is key actuatable from either side in the present embodiment 'of the in vention. 129 can be elevated to the dotted line position, and then two bearing members can elevate and in so doing the upper springs 130 are compressed and the lower springs 13d are extended. This position is indicated by the dotted lines in Fig. 5, Now this barrel structure includes a non-circu 4and when the bolt is thus positioned, the closure lar portion 4Q which is seated in a complementary 20 can be retracted. Further movement oi the bolt operating knobs will result in the subsequent horizontal retraction of the bolt, such movement being limited by the stop 15'1 aforesaid, and then recess in a cam member in the form of an eccen trically mounted circular portion 50. Now when it is desired to lock the bolt in the locked position, the member 50 is positioned as the bolt can assume a lowered position and with shown in Fig. 1. In this position the member 5€! in the outlines oi the closure and its cushioned is in contact with the upper end of the projection bumper structure as shown by the dotted lines 2s or guide member carried by the bolt. Thus immediately to the right in Fig. 5 of the full lines turning of either knob 45 is prevented because the of the catch portion of the bolt. _ bearings cannot move and thus the’tbclt is locked It Vwill be observed that both embodiments of in the locked position. Whenever it is desired to 30 this invention are full equivalents of each other unlockv the structure, the eccentric portion 50 is and both have substantially the same operation. key 'actuated and turned to the dotted'position, It will also be observed that both bolts can be see Fig. 1. This then will permit the> member 29 elevated and lowered from unlocking to locking to be elevated at the upper guide 23 when’ the positionsY for locking in the latter position and handle is turned and this _permits the bolt to be . elevated aswell, stop A25`1imitingV upward move can also be retracted and nested as it were, as shown by dotted lines, so that the bolt does not 'nient as well as the lower face of Vthe upper guide 23. -The' lower position of the aforesaid struc ture is limited by the upper face of stop 24 and the upper face of the lower guide‘23. The interior of the sleeve 61 will be recalled as constitute a ’ projection- on the lead post that might serve to accidentally catch on the clothes of someone passing the closure. i The locking bars or rods 51 and their operative connections to the eccentric arrangement for being non-polygonal as well as the exterior of member 42.
