December This invention relates to fastening means for doors and generallyto mechanism operative-to-secure oppositely disposed or parallel 7 doors in the closed position. More particull larly the present improvements are directed to a novel means'for fastening and controlling doors that afford access from adjoining bedrooms to acommon bathroom.
The primary object of the present improvements is to furnish a novel formof mechanismfor the purpose above referred to which simultaneously fastens or unfastens opposed doors and concurrently operates like indicator devices exterior of said doors, so
that guests in adjoining rooms are notified whenan intervening bath-room, for example, is engaged or vacant.
With the stated and other objects in View I i which will be later on readily comprehended,
my invention essentially consists in the novel features of construction, combinations and arrangements of partshereinafter fully described, illustrated by the accompanying drawings, and defined as to subject matter 51.; and scope in the subjoinechclaims,

Like indicating characters designate the same or corresponding parts in all the views. I
In the typical embodiment of my inven tion=illustrated in the drawings and primarily referring to Fig. I, more particularly, 13, 13 are adjacent bed-rooms having entrant doors 14: 14which are each equipped with the usual washstand 15 and clothes closet 16. In-
termediate the bedrooms 13, is a common compartment-or wash room-l7 enclosing a conventional shower stall 18 and toilet 19; access to the compartment or wash room 17 being had by way of outwardly swinging doors 20, 20, each of which is provided exteriorlyrelative to said roomwith a dead latch or bolt, not shown. All of the foregoing parts are referred'to solely as necessary preface, before describing the application of my present improvement to the opposed wash room doors 20, 20, whereby the occupant of either room 13, 13 may know when said wash room 17 is engaged or vacant; or, when using the wash room, may lock both doors 20, 20 and thereby prevent embarrassing intrusion by another person from either of the rooms 13, 13. y j My novel mechanism is comprehensively designated by the numeral 21 in Fig. I', and, in view of the fact that the several elements or parts thereof at each end of the common operating shaft or lock-bar 22are complemental (or right-and-left counterparts) the following description is mainly limited to an explanation of the mechanism associated with one of the doors 20, only, in order to avoid unnecessary repetitive description.
Referring now, generally, to all the views and more specifically to Figs. VI, VII, X and XI, it will be observed that the operating shaft 22 ispreferably-tubular and of a length somewhat shorter than the distance intermediate the closed doors 20. This operating shaft 22 is journaledat each of its ends-in a bracket 23, conveniently secured to the door jamb 24 and lintel 25 by screws 26-for example. Each bracket 23 is formed with an embossment 27 affording journal bearing for the shaft end with interposition of suitable packing such as felt 28, as well as with spaced members 29 between which pivoted a forked lever or yoke dog 30 under the influence of a recoil spring 31. One end of the spring 31 engages in an aperture 32 of the forked lever 80, while the other end 33 abuts the bracket wall in an obvious manner-to normally hold the aforesaid fork lever in the position best shown by Fig. VII.
Longitudinal displacement of the operating shaft- 22, relative to the bracket 23, is prevented by means of a stop collar ?4 having a concentric recess 85 adapted to accommodate suitable packing-such as a felt washer 36intermediate said collar and the bracket 23. Incidentally, the packings 28, 36 serve as lubricant retainers or absorbers, in addition to preventing metallic contact between the relatively movable parts: or, said packings may be omitted when the parts made of antifrictional material and accurately adjusted so as to avoid any possibility of binding. Screw studs 37 securely attach the stop collar 34 to the operating sl 22.
Snugly fitting each end of the operating shaft 22 is an internally screw-threaded tube or sleeve 38, w iich is longitudinally split at 39Fig. IVfor reception of a key 40, for a purpose later on explained. This sleeve 38 is also provided at diametrically opposed points with screw threaded holes 41, into which the inner ends of the studs 3'? engage; whereby the parts 34, 22 and 38 are rendered relatively immovable, except as hereinafter explained. Threadedly engaging the sleeve 38 is the shank 42 of the latch-device 43 which is fashioned with a head piece 44, preferably disposed at right angles thereto; or, in other words, the latch-device 43 is of T-formation, with the head piece 44 conveniently although not e sentiallypolvgonal in cross section, as best illustrated in Figs. III and IV. The shank 42 of the latch-device 43 is provided with longitudinal grooves 45,-that are diametrically opposed, into either of which the key --hereinbefore referred to-is adapted to co-operatively seat in locking the 1,s15,5eo
Referring again to the forked lever or yoke dog 30, it is to be noted that the heel portion 48 thereof projects laterally through an opening 49, in the bracket 23, into the path of a segmental enlargement 50 of the associated stop collar 34; and that the bracket 23 is formed with an offset 51 in the path of movement of said enlargement, as best disclosed in Figs. X and XI. Furthermore, it will be observed that the stop collar 34 is radially notched at 52 for semi-reception of the heel portion 48, of the forked lever 30, when the associated door 20 is in the open position; whereas the forked end of said lever receives one limb or portion of the latch-device head 44, as clearly illustrated in Figs. XI and VII, respectively. Thus it will be readily understood that when the door 20 is in the open position, the operating shaft 22, stop collar 34 and latch-device 43, are all simultaneously and automatically fastened to the bracket 23 against any illicit or rotative movement under recoil action of the spring 31. This feature I deem of importance, as it not only prevents the mechanism from being accidentally or maliciously put out of commission, but it also serves as an effective safeguard against the wash-room 17 being closed to either of the rooms 13 unless said wash-room is occupied or in use.
In combination with the mechanism above described I employ a cupped keeper for attachment to the door 20, as by screws 54, said keeper having a lateral openinp 55 for free entry and withdrawal of the latch-device head 44 in securing and releasing the door 20, as hereinafter explained. Incidentally, as will be best understood from Fig. VI, the latch-device head 44 is beveled along its longitudinal angular edges to facilitate turn ing in the cupped portion 56 of the keeper 53.
Associated with the keeper 53 and actuable by the latch head 44 is an indicater device comprehensively designated by the numeral F7. This indicator device 5? comprises a tabular actuator 58 having a discous portion or flange 59 appropriately marked with the legens Open anc Shut d ig. XII; said legends being moved into registry with a sight aperture 60 in the indicator closure casing 61, that is provided (for example) with apertured lugs 62, whereby it is attached to the door 20, as by screws-mot shown. Journal bearing, in the door 20, is afforded the tubular actuator 58 by means of a sleeve 63, secured therein through the medium of an obviously, theacltnator. 5.811s made. an. easy work-v mg; it n the bearing sleeve 65, and it, is;

Lock. By drawingupon thechain 69 markeds Lock, the operating shaft 22 is given a. partial (quarter). turn, to the right which moves the latchsdevice. headv 44 from theposition shownfinFig. Y'I'II, to that illus trated by Fig. IX. Concurrently-with. the operation ust describedthe associatedindica tor disc'59 will be correspondingly turned and the legend Shut of the devices 57 in both rooms 13 simultaneously swung intoregistry with the-sight apertures 60 whereby the occu ant rothers'in either of said rooms is noti ed that the wash-room 17 is engaged. Attention is particularly directed to the fact that closure of the doors 20, releases the forked levers 30 from the position shown in Fig. VII to that of F ig: VI, and thereby permits turning of the operating shaft 22 which is otherwise secured at all times against such movement by the forked levers 30, as hereinbefore set forth. Pull upon the chain 69 marked Open obviously effects a reversal of the operative cycle just described, whereupon both doors 20 are released for normal opening and closure.
From the foregoing it will be self-evident that my novel fastening mechanism fully justifies all the objects and advantages set forth in the opening statement of invention;
and, while I have disclosed one practical embodiment thereof, it is equally apparent the same is susceptible of diverse changes without departing from the spirit and scope of said invention. Accordingly, the right is hereby reserved to make all such changes as fairly lie l- Iiastening mechanism, for a se ies. o l$SOC121iZGCl doors comprising a commonrotary V actuator with. headed termini. a apted; to do:
