DOORLOCK.

Application :filed November 23, 1925. Serial No. 70,739.

My present invention relates to .door locks and more particularly to locks tor use on garage doors, shop doors and like places l where it is desirable to make the door fast along its top and bottom edges and where it is also desirable to effect the locking engagement automatically upon moving the door into closed position, and my invention has for its main object the provision of an improved door lock of this class which will embody certain desired features of simplicity, efficiency and convenience and which will be economical in manufacture.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements ot' parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part oi` this specification, and in which,

Fig. 1 represents an edge elevation of a door equipped with my improved lock, the frame parts above the door and the floor parts below the door being shown in section;

Fig. 7 represents a section through the center piece and barrel, this View being taken substantially on the line 7 7 of Fig. 5 and showing how a common type of cylinder lock may be operativ-ely associat-ed with the barrel of my center piece;

Fig. 8 is a face view of the center piece and barrel associated therewith, this View being taken on the line 8 8 of Fig. 7; and.

Fig. 9 represents a tace vi-ew taken on the line 9 9 ot Fig. 7.

lith more particular reference to the parts illustrated in the accompanying drawings, 10 and 11 designate the cooperating` doors of the garage 12, the doors being of any customary type hinged as at 13 tor outward swinging movement and one of the doors, herein illustrated as the door 11, being furnished with a vertically extending` edge strip 13 which suitably over-laps the adjacent edge o the door 10 whereby, when the doors are closed, to secure the door 10 in closed position by means of the strip 13 on door 11. In the present exemplification, therefore, my improved lock is illustrated as applied to the door 11.

The preferred embodiment of .my invention as illustrated in the accompanying drawings, comprises a center piece 14 having a base flange 1.5 and a centrally pron jecting boss 16. This center piece is provided with a central bore 11' offset inter mediate its length to provide a shoulder 18. Tui-nably fitting the bore 17 is a barrel 19 which is made with a .shoulder 2Q adapted to butt against the shoulder 18 so as to pre vent the removal of the barrel in a direction out through the boss 16. Said barrel 19 has a part 21 which protrudes beyond the extremity oi the boss 16, and this protruding part is provided with a diametrical aperture 22. The barrel 19 also protrudes for a distance beyond the base end 15 of the center piece; and extending inwardly through this protruding part, which is designated by 23, is an opening 24 which is preferably ot angular form in cross section for a reason presently to appear.

The center piece 141 is applied to the inner *face of the door 11 along the free edge thereor and midway the distance between top and bottom ends of the door, the center piece being applied by placing the base flange 15 flat against the inner tace of the door and itting the protruding barrel portion 23 into a suitable opening 24 provided transversely through the door 11, and, as herein illustrated, through the lapping edge strip 13. rThe center piece is rigidly secured to the door by means of screw elements 25.

The barrel 23 of the present invention may be operated from the outside of the door by any suitable means; but the same has been especially designed for use in connection with a lock 26 oi' the cylinder type, having a key operated rotatable barrel 27 with which is associated a projecting bar 28. The lock 26 is applied in the usual way to the door 11 with the rotatable barrel seated in the bore 24 and the bar 28, `which is of square formation in cross section, interlocking with the barrel opening 24. By this arrangement the barrel 19 of the center piece is connected with the key operated barrel 27 ci the lock, whereby the barrel 19 will be rotated with the rotation of the barrel 27. A flexible member 29 in the form oi" a .chain is taken through the opening 22 or the barrel 19 and is made fast to said barrel by means of .a pin 30 arranged therein so as to engage one of the links ol1 the chain. vv@ne end of this chain is Iattached to a latch 3l pivoted on a pin 32 arranged in the. opposed lugs 34 of a bracket which is secured by means of screw elements 3,6 adjacent the top edge of the door 11. The latch 31 is yprovided with teeth 37 adapted to interlock with similar teeth pro 'ided on keeper or catch 38 which is Vsuital'ily secured to the overhead tra-ming or wall 39. The `latch 31 is normally urged into position for engagement with its keeper by means Vot' a `pull spring 40 which has one end secured at 41 to the baseoi the bracket and the. other end secured at 42 to the inner end ot the latch at a point inwardly ot the pin 32. The opposed lugs 34 are Vconnected by a back piece 43 which serves as a stop against which the latch Iabuts under the influence ol lthe spring 40. The pin 32 serves as a horizontal axis igor the latch so that when the barrel 19 is :turned causing the chain 29 to wind on the protruding portion 21, the latch 3l will be withdrawn from its keeper.

The opposite or lower end ot the chain is attached to a drop latch 44 movable 'on a pin 45 arranged on lugs 46 provided on a bottom,- bracket 47 attached at the bottoni edge of thc door. 'lhe latch 44 is provided with teeth 4S adapted to interlock with correspondingly termed teeth on a .keeper 49 which is secured to the floor-board 50 below the door. The bracket 47 has a back piece 51 which serves as a stop to limit the down` ward movement ot the latch 44. ils `in the previous instance, the latch 44 is withdrawn from its keeper when the chain `29 is turned upon the protruding port-ion 21 under the turning n'iovement of the barrel 19.

To .open the door 11, the barrel 27 of the cylinder lock is operated by a key in the usual way with the. result that the barrel 19 is turned and the chain winding on the protruding .portion 2l withdraws both the top and bottom latches from their keepers. llE the door is to be opened from the inside, it is only necessary to pull the chain towards the barrel 19 or to turn the barrel 19 troni the insidev` eitherl el: which actions results in the withdrawal ot the latches from their keepers. `When the door is closed the latches 531 and 44 automatically interlock with their keepers; the top latch 31 being' normally held in position by the spring 'for engagement with its keeper -while the botto-1n latch 44 drops ot' its own weight into position for engagement with its keeper.V Both the top and bottom latches with their keepers are provided with suitable cooperating cam edges 52 and 53 to enable the latches to interlock with their keepers when the door 1l is closed.

While l have illustrated and described the preferred torna of construction vcarrying my invention into efect, this is capable of variation :and modification without departing from fthe spirit of the invent-ion. l', therefore, do not wish to be limited `to .the precise details yof `construction set lort'h, but desi-re 4to avail myself ot such variations and modifications as come within the scope tot the appended claims.

'Having described `my inyention, what l claim as new and desire to secure by Letters Pat-.ent is:
