With the foregoing and other objects in view,

my invention consists in certain novel features of,

construction and arrangement of parts that will be hereinafter more fully describedland claimed and illustrated in the accompanying drawing inA which:

Fig. 1 is a vertical section taken'through the center of a garage door and showing the same equipped with my improved latch and lock.

Fig. 2 ls an elevational view of the latch as seen looking in the direction indicated by the arrowV 2 in Fig, 1 and showing a portionv of the garage iioor in section. y

Fig. 3 is a vertical section taken on lthe line 3--3 of Fig. 2.Y

Fig. 4 is a horizontal section taken .on the line 4 4 ofFig. 3. l

Fig. 5 is an enlarged horizontal section taken approximately on the line 5-5 of Fig. 1.

Referring -by numerals .to the.v accompanying i, drawingfwhich illustratesa preferred embodiment of my invention, I0 designate's'fa; 'garagedoorfot conventionalconstruction and by 'means of arms I I 'secured-to theinner face of the-'door and pivoted1 at I2 .to suitablev supports Awithinthe garage,

this door is adapted'to swing from its normally' closed vertical fposition `upwardly yand*v inwardly toa'substantially horizontal position lthe upper end of the door openingasfshown by dotted lines mFigIl y,

A keeper I3, preierablyof metal rand provided Awith a horiz.orltallydisp'osedv opening I4, ifs"pos ii tionedponl the surfacpfthe garage Qor which is usually formed of concrete, and to anchor this keeper in Aposition :aninteeral studl projects from theunder side offsad keeper downwardly'into the lfloor-an'dsaid studlbeing provided witharhead 14a and an aperture I5. The top I6 of the keeperY or that portionr above` the opening I4 isinclined toward the door openingand'theinner er forward edge of said inclined uppery portion is'roundedor beveled as designated by "i1 imm'edately'abovejits lower edge isr aj metal plate`v I8j with which isfor'r'nedl integralfak pair of ears IS and passing through saidears'is a'pin or bolt I `20 that is retained iny position byjymeans ofr a cotterl pin "2 I J ournalled onA the vor bolt 2li;v between ears I9 is a short'horiz'ontally disposed arm 22 provided on its free end with a depending hook 23v and the end of this hook when the door isy closed, projects into the opening I4 inl keeper ,I3 beneath the inner portion of the upper part IS of said keeper.

.Passing around pin or bolt 20 between the arm i 22 and one of the ears I9 is the coiled'portion of a spring 24, one endof which bears against plate I8 and the other end bearing against a shoulder 25 on the side of arm 22,` thereby tending to force the free end of the arm 22 downwardly andv con-A l sequently maintaining the hook 23 beneath the upper lmember I6 of the keeper.

Formedintegral with the lower end of platev I8 is an outwardly projecting lug or linger 2S'which when the door is closed, projects into the reary portionof the opening I4 in the keeper opposite from the pivoted'hook 2 3. Thus when the latch is engaged with the keeper, the lug' or ringer l2t i 'y prevents the door from beinggopened by insert-k i f ing a lever or the like beneath the lower edge of the door and prying the same upwardly andthe y hook 23 prevents the lower portion of the door v this member is provided with a loop` 32 that'passes around the wrist pin of the crank 29.

AY retractil@ spring 30a is connected to the end@` y' of crank arm 29 and to the garage door at a point aV substantial distance' below the shaft 23 and which spring cooperateswith spring `24 in vreturning the hook 23, member 30, and crank arm 29,1170 their normal positionsrafterfhaving. Y

actuated to release the hook from the keeper been I3.

Whenthe latchis in engagement with.v the keep- `er I3, the crank arm occupies a vertical-position as illustrated, in Fig. 1. l, Shaft 28 projects a vshort :distance'outwardly through thedoor I0 and loosely mounted on said projecting` portion is a handle 33having-associatedtherewith a short housing dthat encloses a vconventional keyv operated lock `of the type wherein the Yinsertion and-manipulation of `the key locksfthe handle to shaft 28;

Locking handles of this type are extensively used on the doors of motor vehicles.

Thus it will be seen Athat I have provideda garage door latch'andlockthat is relatively simple in `constriuztion, inexpensive of manufacture fand very effective in performing the functions` with the parts so positioned, the door can be Y' swung outwardly, upwardly, and then inwardly to itsl open position as shown by dotted lines in Fig. 1. i y

When the door is swung from open to closed position, `the hook 23 rides upwardover `the inelined upper surface of the member rI6 of the for which it is intended. l l l It will be understood that minor changesfin the size,. form and :construction of thev various parts of my improvedgarage door latch'and lock, may bemade and substituted for those herein shown kand described,l Without departing, from` the spirit of-vmy invention, Athe scope of whichis setforth vin the appended claim.` Y l Iclaimas myinvention# v A garagedoor latch comprising-,I
