The main objects of this invention are:

First, to provide a lock and latch means for upwardly acting doors and the like which may be locked and released from the outside by means of a key and may be manipulated from the inside without the use of a key.

Second, to provide an upwardly acting door structure of the type in which the door is slidably supported on tracks in which the tracks are provided with bolt receiving keepers in which the lock means is not subjected to substantial stress in the event that an effo-rt is made to pry open the door when it is locked.

Third, to provide a lock and latch means which is readily adapted to doors of varying widths.

Fourth, to provide a lock and latch means which may be readily adapted for use with a single bolt or with two bolts.

Fifth, to provide a latch and lock means adapted for use on slidable doors which may be adjusted for positioning the bolt into coacting relation to keepers disposed at either side of the door.

Sixth, to provide a latch and lock means including a housing and a bolt slidably mounted on the housing and projectable therefrom to keeper engaging position with actuating means disposed within the housing, parts thereof being adjustable to project the bolts from either "side of the housing.

Seventh, to provide a latch means in which the parts may be economically produced and assembled and one in which the bolts are automatically retracted and held in retracted position when the lock means is released.

Objects relatin to details and economies of the invention will appear from the description to follow. The invention is defined and pointed out in the claims.

FIG. 10 is an inside view of the lock and latch assembly embodying my invention as shown in- FIGS. 8 and 9.

In the accompanying drawing applicant has illustrated his invention as adapted to upwardly acting doors ofthe sectional type comprising a plurality of sections 1 conneoted by the hinges 2 which, in the embodiment illustrated, support the rollers 3 which coact with the tracks 4 of inwardly facing channel cross section. A portion 5 of the wall of a garage or the like is conventionally illustrated. It will be understood that the tracks are provided with so called overhead portions which are not illustrated as they form no part of this invention.

The door is provided with a counterbalance means designated generally by the numeral 6 which has pulleys 7 for the cables 8. Details of this counterbalance means are not illustrated as they form no part of the appl-icants present invention.

Applicants latch or bolt lock means in the embodiment thereof, illustrated in FIGS. 1 to 7, comprises a housing designated generally by the numeral 9 and including a front wall Iii, top wall 11, bottom wall 13 and side Walls 14. The housing in this embodiment is formed as an integral stamping and the top and bottom walls are provided with outwardly projecting flanges 15 which. have openings for the attaching screws 16 by means ofwhich the housing is generally connected to the door panel 1. The side walls of the housing have slot-like openings 17 therein in which the bolt member 18 is slid ably supported. This bolt member in the embodiment illustrated has an outer section 19 pivotally connected thereto at 20.

The embodiment illustrated in FIGS. 1 to 7 is provided with a second bolt member 21 disposed with its inner end below the housing. These

bolt members

19 and 21 are slidably supported adjacent their outer ends by the bracket or guide member 22 fixedly secured to the inner side of the door. Thebolt coupling member 23 is mounted on the pivot or spindle 24 provided with a handle 25 on the outer side of the door, and with a handle 26 on the inner side of the door, see FIGS. 1, 2 and 3. This bolt coupling and actuating member is actuated to bolt retracted position by means of the spring2'7, one end of which is connected to the bolt coupling and actuating means at 28 and the other end to the housing wall at 29, see FIG. 5.

With this arrangement the bolts are retracted by the spring 27 upon the releasing of catch 30 which is pivotally mounted at 31 on the front wall of the housing which is provided with a bearing 32 therefor, the front wall being provided with a similar bearing 33 for the spindle 24.

The catch or latch member 36 is actuated to engaged position by the spring 34 connected to the lug 35 on the latch member and to the side wall at-36;, see FIG. 5. This latch member is provided with a fingerpiece 37 projecting through an opening or slot 38 in the top 11 of the housing. The housing is provided with a slot 39 in its bottom wall through which the bolt coupling and actuating member 23 projects and to which the inner end of the bolt member 21 is pivotally connected at 40.

The lock barrel 41 is supportedly mounted in the bore 42 in the door. The lock spindle 43 may be adjusted only from the outer side of the door as by the key 44. The spindle 43 engages the catch member 30 so that it may be tionship' of the garage to a house or other building. 'ing these points in mind, attention is directed to FIG.

disengaged from the keeper 45 on the bolt coupling and catch in engaged position, as illustrated in FIG. 5, it cannot be released by manipulation of the handle 25. in other words, the'handle is locked and also the bolts cannot be disengaged through the handpiece 26 from the inner side of the door but the latch 30 may be released by the handpiece 37 and the bolts are retracted by the spring '27. They maybe adjusted to locking position from the inside of the door but the latch 30 may be released by the handpiece 37and the bolts are retracted by the spring 27. They may'be'adjusted to locking position from the inside of the do'or'by means of the handle 26.

The bolts and coacting parts are illustrated in their retracted position in dotted lines in FIG. 3. In the embodirnent illustrated the rails are provided with holes 48 which constitute keepers for the bolts, see FIG. 3.

'In'the embodiment of my invention shown in FIGS. 8

'and 9 the door sections Ell are somewhat modified in structure from that shown in the other figures but it should be understood that this is not important as to the structural features of my present invention but it does illus- 'tr'ate a type of door which is in extended commercial use.

The tracks 4 are substantially those shown in FIGS. 1

and 3.

Theibolt and latch housing and support member 1% of 'this embodiment is the same as that shown in the embodiment of FIGS. 1 to 7 inclusive. However, it should be understood that the bolt'rnember 51 illustrated in these FIGURES 8, 9 and 10 has the same shape on both ends and either end is adapted to be engaged with the keeper "4:; of either track. See FIGS. 8 and 9.

The

handles

25 and 26 on the inner and outer sides of the door are the same as in the embodiment of FIGS. l-7 inclusive, however, in FIGS. 1-7 inclusive two simultaneously actuated bolts are provided for engagement with both tracks. In the present embodiment a single bolt 51 is provided which corresponds generally to the bolt mem- *ber 18 of'FIG. 3.

' It will be noted that in FIG. 8 the lock member is mounted on the left hand side of the door viewed from the inner side thereof and in FIG. 9 it is mounted on the right hand side of the door and in commercial practice this positioning is varied according to the manner which is most convenient for manipulation, for example, the rela- Havin which the bolt'is shown projected to the left in the figure but it would be projected to the right as shown in FIG. 9 when applied to a door.

The latch-member 39 is provided with corresponding lugs 52 uniformly spaced from the pivot for the latch member and engageable with the keeper 45.

It shouldbe noted that FIG. 10 corresponds in structural details to FIG; 5 with the eXception that the bolt 51 has en d portions, both of which are adapted to engage a keeper when'in projected position and the only change in the "structure is the elimination of the bolts 19 and Z1 and the shortening 'of the bolt 18 to adapt the structure to jp'ositioning adjacent the track, as is illustrated in F165. '8' and 9.,

It should be understood, as stated, that the embodiment as shown in'FIGS.8, 9 and 10 is an adaptation of my inventionto the use of a single bolt and that it illustrates that the lock means is adapted to be positioned on either side of a door. It is a structure more economical to produce "than that of FIGS. 1-7 inclusive but it does not have bolt 4 means for engaging keepers on both sides of the door which is an advantage in anchoringly locking both sides of the door which vary considerably in width.

1 have illustrated and described my invention in highly practical embodiments thereof. 1 have not illustrated or described other embodiments or adaptations as it is believed this disclosure will enable those skilled in the art to embody or adapt the invention as may be desired for particular installations.
