This invention relates to certain new and useful improvements in door locks especially designed for barns and garage doors and has for its primary object to provide a'door lock in which the lock mechanism can be operated from the outer side of the door only after the release of a control` devicel on the inner side of the door.

A further object of the invention is to provide a door lock of the above type wherein plurality of sliding tumblers are engaged with a sliding bolt to hold the latter in a projected and locked condition with devices associated with the tumblers to `edect operation thereof for shifting them to releasing positions from either the inner or outer side of the door.

A still further object of the invention is to provide a lock of the above type wherein acl cess to the sliding tumblers from the outer side of the door is controlled by ya device` operable from the inner side of the door to permit the lock mechanism to be operated from the outer side of the door only when desired,

lVith the above andv other objects in view that will become apparent as the nature of the invention is better understood, the same consists in the novel form, combination and hereinafter more fully described, shown in the accompanying drawings and claimed. l

In the accompanying drawings wherein like reference characters indicate correspending parts throughout the several views,

Figure 1 is a fragmentary front elevational view-'of a barn or garage with the vehicle entrance door equipped with the improved lock structure and also illustrating a smaller door equipped with a key operated lock; f

Figure 2 is a fragmentary rear elevational view of the door .showing the inner face of the lock casing and the'device for controlling the insertion yof the tumbler operating key into the loch casing at the outer side of the door; Figure 3 is a fragmentary rear elevational view, similar tov Figure 2 with the inner is also operableat face plate of the lock casing removed, the l Figure 5 isa similar rear elevational view with the hey-for operating the sliding tumblers inserte-d in the lock casing;

Figur-e 6 is a vertical cross-sectional view talren on line 6-6 of Figure 2;

Figure 7 is a vertical cross-sec`tional view taken on line (2-7 of Figure 2gjan'd f Figure 8 isa perspective view of the sliding tumbler operating lrey.

Referring more. in detail to the accompanying drawings, in Figure 1 there is illustrated a barn or garage `1 having a vehicle door opening therein closed by the door 2 that is equipped with the. improved loclr structure 3, while the barn or garage 1 further` has la smaller door opening closed by the door 4.'

The improved lockv structure 3' is shorwn in detail in Figures 2 t0 8 and comprisesV a rectangular casing the door 2 in a manner as shown 1n Figure 'Twith a removableface plate 6 for the loch casing disposed at the inner side of the door 2.

A sliding lock bolt lower end of the casing 5 and is provi-ded at its upper edge with spaced recesses 8 separated. by lugs 9; The nose 10 ofthe bolt 7 is adapted to be' projected through an opening in the end wall of the lock casing 5 for reception in a keeperV socket provided in the doory frame 11.- "The opposite end of the sliding bolt- 7 extends through the side wall of the casing 5 at the outer side of the door2 as shown inFigure1 and is pro- 7 is mounted in the OFFICE.

5 set into an opening in ill) vide-d with a, handle or gripping block y12.

As shown in Figures 2 to 7 the open side of the lock casing 5 has an outwardly di` rected flange 5a with anarm extension 13 aligned with the bolt '7, the arm extension 13 being provided with a slot 14; through which the rod 15 carried by the handle end of the sliding bolt 7 projects at the inner side of the door. It will thereforevbe seen that the sliding inner side of the the outer side Vof the ydoor by the handle or gripping block 12.

A pluralityrof sliding tumblers are'associated ywith the upper recessed edge of the sliding bolt 7 f the` vertically Vsliding tumbler bars 16 being maintained in spaced relation bolt 7 is operable fromthel door 2 by the lrnob 15 and.

bythe spacer bars 17 secured tothe integralr i face plate-of the loclrcasing 5 as shownin `Figurese, 5 and 7. The sliding tumbler bars 16 are of a width to be received in the spaced lugsf) atthe upper yedgerof the `slid ing bolt 7. Willen i'he3bolt is projected las shown in Figure 5, the sliding tumbler bars 16 gravitationally dropinto spaced recesses S'a'nd retainthc b'oltin its projected and locked condition.V `'llo release the bolt from the inner side of the door 2, a short rod or similar ydevice `is siinultaneouslyy engaged with" all of thegliandle'slS for elevating the tumbler ,bars to displace the lower ends i thereof from the,sliding path of movement y the inner'sicleof the door,

oo b

tudi'nally' groved `head vthe sliding tumbler bars ofthe sliding bolt. i y y y The release of the-slidingtnnihler bars 16 from the outer side ot' the door is accomplished by the key or operating bar shown in Figure 8, .Asshown in Figures `5 and 7, the partition `bar 17 has the edge thereof adjacent the closed ivall of `the lock casing out awa to provide alignedreeesses 2() while each sli ing tumbler bar 16` is also provided on the corresponding side edge with a recess 21, the recesses 2O andf 21 as shownr in Figlure 5 being=aligned With each other when arelowered into engavement with the ysliding bolt 7. The side Wal of the lock casing 'above the handle or gripping block 12,.as shown in Figure 6,

1s provided with any opening 22 aligned with therecesses 20 and 21. 'j y n i Thekeybar28 shown in ,Figure 8 having a. handle 24 upon one end thereof is provided on its upper edge Withspaced lugs25 deiiningfspaced recesses 2G that are inserted through the opening 22 in thel lock casing to assume the position shown in Figure 5. It Will now be seen that .with the key positioned asshownn Figure 5, upward `move- --mentlof the key will 'engage the sliding tuinbler bars 16 to elevate the same to disengage thek lower ends thereof from the sliding bolt 7 and Apermit the latter to be shifted by the gripping block12. i i' A closure plate is associated with the openig722 in the sidey Wall of, the lock cas- V p "a:` handle for each tumblery bar ex osed at ing 5 and nits position with respect to said openingiis controlled' by devices carried by 4the closurey plate 27 being-,liiited i'n its `sliding movement y a pin and slot` mounting, carries a longi- 28 at the inner end thereof that is exposed'at the ,inner side of tl1"e"`dl`aorg2.;v *A bearing i upon the' ange' 5'* atfthe immer side` of the door in said groove 28 and has one end of block 29 is .mounted the latch rod 30 pivotallysupportcd therein. The latch rod 30 is adapted to be moved npwardl on its pivotal support from the positionslibvn inFigure 5 tothe position shown in Figure 4 with the intermediate portion thereof` received in the grooved head 28 of they platev27 andwith the lree end received between the spaced apcrtnred lugs of the keeper 31 with which a retaining pin 32 is associated.y It will therefore be seen that vvhen thelatch rod 30 is engaged with, the keeper 31, sliding movement of the plate 27 with respect to the key entrance opening 22 to the lock casing is prevented.`

4 From the abovedetailed description of the invention, it is believed that `the crmstrur tionandA operation thereofwill at once he apparent, it being notedthat the sliding holt 7 is operable from the inner side of thc door by simultaneously `,disengaging the sliding tumbler barszl therefrom and shifting thc boltu by the knob 15, while the sliding bolt is also operable from the outside of the door Cil closureplate 27 for the opening 22, the lock may still be operatedroin the inside oi the door but operation thereof from the outside ofthe door is prevented. It is therefore necessary to enter the barn or garage 1 through the small door 4 for disengaging the latch rod 30 from its keeper to permit use of thekey 23 from they outer side of the door. `l/Vhen thebarn or garage Vdoor 2 is lockedat night, the latch rod 3() is engaged with the plate head 28, but when the vehicle,

garage ,during is removedfrom rthe barn or the day time, the latch rod 30 may he disengaged from itskeeper 31 to permit operation of the lock mechanism' from the outer side of the door. y y y i y While there is herein shown and described the preferred embodiment of the present invention, itis nevertheless to be understood that minor changes may` be made therein without departing from' the spirit and scope of the invention as claimed. y
