R RATZLAFF' GARMENT LOCK 'FiIed Nov, 23, 1946 Get. 31, 1950 Patented Oct. 31, 1950 UNITED STATES PATENT OFFICE 10 Claims.

This invention relates to a garment lock and the object thereof is to provide a lock having a two-part hasp in which one part is movable in the lock body toward or from a stationary part to hold an article, such as a coat or other garment, between the two parts of the hasp.

It is further a feature of the invention to provide a garment lock having a movable hasp and a stationary part including a projectable pin for entering an aperture in the opposed end of the hasp and a casing supporting the pin which is slidable in an aperture provided therefor in the casing, provision also being made for the insertion of a non-rotatable key in an aperture in the casingto engage a series of tumblers, the key having a series of stepped portions at its end alignable with the tumblers in the manner hereafter more fully described, whereby insertion of the key positions the tumblers with the slots therein in alignment, means being provided to release the element engaging in the notches as the hasp is moved to locked position wherein the slots in the tumblers are out of alignment one with the other, as shown in the accompanying drawing in which Fig. 1 is an elevation of the lock with the cover removed and the hasp in locked position.

Fig. 6 is a section taken on line 66 of Fig. 2.

The lock according to my invention comprises a casing shown in Fig. 1 with the cover [11' thereof removed and showing the lock in the position assumed when the parts are in locked relation. The hasp 2 has an end 3 provided with a flat surface 4 on the inner side and providing an outwardly extending end portion 5 which is longitudinally movable in the aperture 6 in the inwardly extending flange 1 integral with the wall 8 of the casing l. The hasp 2 has a U-shaped end portion 2a terminating in an end 2b, the face 20 of which is provided with a series of projections and recesses with the latter aligned With the recesses 2d of a plunger 9 and which is also provided with an aperture Ilia to receive a pin H3 projecting centrally from the end of the plunger 9. This pin I0 is formed integral with a cylindrical end I I of greater diameter positioned in the recess I2 in the plunger 9. A spring I3 is positioned in the recess and engages the said end ll of the pin Ill.

The opposite side walls of the plunger 9 have parallel side faces 90 and ed as shown in Fig. 6,

A keeper M has one end apertured to receive the portion 3a of the hasp which has a flat surface 319 engaging a similar surface of the keeper M as shown in Fig. 2. The keeper is held in position on the end of the hasp by a pin 30 and the slotted end Mb of the keeper [4 engages the opposite parallel surfaces 90 and 9d of the plunger 9 as shown in Fig. 6 thereby holding the same fromq A coiled spring 16 has one. end engaging the recess 91) adjacent the distal end of the member 9a and the opposite end of th spring engages the under side of the lug l5 which is integral with the casing. The spring 16 tends to hold the.

plunger 9 in contact with the upper face of the fiat spring H, which has an inwardly extending end l8 and the opposite end is provided with an aperture l9 through which the cylindrical mem-, ber 90; loosely extends. The aperture I9 is greater in diameter than the diameter of the cylindrical member 9a. The end l8 of the flat spring I! engages in the notch 20 of the two lever elements 2| and 22. When the parts are in the position shown inFig. lthe fiat spring 11 is moved downwardly under compression by the hook ends 23 of the levers 2| and 22 and is turned on the lug 15 as a fulcrum thereby tending to force the plunger 9 upwardly. These levers 2| and 22 are joined together by a plate 28 and are mounted on a shaft 25 which extends from the rear wall of the casing I and against which bears the upper surface of the hasp locking plate 26.

Leaf spring 24 bears against the under surface of hasp locking plate 26 and has one end thereof secured within the inturned end 21 of plate 28. The right end of plate 28 has an angular tongue 29 intermediate its spaced depending flanges 39.

A shaft 3| parallel to the shaft. 25 is supported by a side wall of the casing. A trigger 32, which.

is of plate like form, has spaced side flanges 33 pivotally mounted on the shaft 3 I. These flanges 33 have projectin portions 34 that engage the flanges of the plate 28 On each side of the inbent tongue 29.

By'movement inwardly of the hasp against thetension of the spring 35 the edge 5 at the inner end of the hasp engages an edge of the trigger 32 which is normally beneath the said edge, as shown in Fig. 2.

This nward movement of the hasp turns the trigger 32 and the ends 34 thereof engage the flanges 3B of the plate 23 and thus turns the levers 2| and 22 on the axis of the shaft 25 thereby tilting the fiat spring upwardly at its left end against the tension of the spring l6 and thus tends to roject the plunger 9 outwardly of the casing I.

There are a series of tumblers 36 of plate like form on the shaft 39 each having a radial slot 36 into which an end 37 of the lever 38 may extend when the slots 36 of the tumblers are in alignment longitudinally of the supporting shaft 39.

When the hasp has been moved inwardly to the position shown in Fig. 1 the pin l enters the recess Illa. The end portion engages the trigger 32 turning the same in a clockwise direction on the shaft 3| and, due to its engagement with the flange 30, levers 2| and 22 are tilted counterclockwise and the plate 26 is turned upwardly under the action of spring 24 as shown in Fig. 1 with the flat spring I! compressed downwardly on the lug i5 to the locked relationship of parts shown in Fig. 1.

Consequently this clockwise movement of the trigger 32 and its projections 34 about pin 3! effect a counter-clockwise pivotal movement of the flanges 30 and tongue 29 as well as the levers 2| and 22 and their connecting plate 28.

Tongue 29 moves from the position of Fig. 2 to the position of Fig. l and operatively engages the upright projecting right hand end 45 of the lever 38 which extends around the pin 3|. This causes a pivotal movement of the lever 38 clockwise around the pin 3|, lifting the tumbler retaining end 31 of said lever out of the respective slots of tumblers 36'. The tongue 29 is thus confined between the right hand end 45 of lever 38 and the upturned opposed portion 46 of lever 38 when the lock is in the locking position as seen in Fig. l.

Tumblers 36' rotatably mounted upon casing supported pin 39 are thus released, and are urged by their respective springs 49a to the position shown in Fig. l, with their lower edges resting upon rib 39a within the casing, and with their respective slots 33 out of alignment.

When the hasp 2 is moved inwardly to closed position, trigger 32 rotates clockwise, and levers 2| and 22 and their interconnecting plate 28 pivot in a counter-clockwise direction on shaft 25 and the leaf spring 24 carried by plate 28 tips the hasp locking plate 26 in a counter-clockwise direction about the pin 25 as shown in Fig. 1.

In Fig. 2 the hasp shaft 3 is free relative to the opening in the locking plate 25, however after I the plate 26 has turned to the angular position of Fig. l and the upper enlarged end 3a of said hasp is positioned in the opening in the hasp retaining plate 26, then the opposite corners of said opening frictionally engage and retain the shaft end of the hasp effectivel securing the same in its innermost locked position.

The rib 39a is integral with the casing and has a slot 40 opening through the outer face of the casing as shown in Fig. 2 and into which the key 4| may be introduced.

The key has a rib 42 in one fac thereof which rides in the groove 43 on insertion of the key. The key has an end portion formed of a series of steps a, b, c, d and upon insertion in the slot 39' the stepped portions successively engage the tumblers 36' projecting the same about their shaft 39 until their respective slots 36 are in alignment to permit the end 31 of lever 38 to enter said slots as shown in Fig. 2.

When the hasp 2 was initially closed to locked position the forward ends 23 of levers 2| and 22 place the end l8 of leaf spring ll under substantial compression. This compression is transmitted through the plate 28 of said levers and to the tongue29, which as shown in Fig. l is bearing against the right end 45 of lever 38. However this compression is transmitted through tongue 29 so that it operatively engages the opposed portion 43 of lever 38 adjacent pin 3| tending to tilt the same in a counter-clockwise direction about pin 3|. Just as soon as the key 4| has aligned the slots 36 of the tumblers 36 the lever 38 is free to so tilt about the pin 3| under the action of the tongue 29 urged by the compressed leaf spring |'||8.

Consequently the end 37 of lever 33 moves into the slot 35 of said tumblers, and this motion releases the lower end of the tongue 29 from between the right end 45 of lever 38 and the adjacent opposed portion 43 thereof which extends around the pin 3| Tongue 22 and its levers 2| and 22 are free to pivot in a clockwise direction about the pin 25 under the expansive action of the leaf spring |l |8, to assume the position shown in Fig. 2. At the same time the hasp locking plate 26 is pivoted in a clockwise direction about the pin 25 to automatically release the hasp 2, the latterthen moving outwardly of the casing under the expansive action of spring 35. V

The ke 4| is non-rotatable in the slot 49 and, to unlock the hasp, the key is simply moved inwardly of the casing.

By moving the hasp inwardly from the position shown in Fig. 2 to the position shown in Fig. 1 both springs I3 and 3 are placed under tension and the spring 35 is also under tension by the portion 3 of the hasp.

It will be noted that when the hasp is moved to locked position the plunger 9 is resiliently urged into engagement therewith and, due to its having flat surfaces and 902 on each of its opposite sides, it is non-rotatable in the recess of keeper 4 and thus the corresponding ends 20 and 2d are in registry and the article of clothing is thus secured between the end 2b of the hasp and the opposed notched end of the member 9.

It is further pointed out that the plate 26 is limited in the extent to which it may be turned by means of the pin 44 secured in the side of the casing as will be understood from Figs. 1 and 2. i It will be realized from the foregoing that the key is only utilized to unlock the device. When in the unlocked position shown in Fig. 2 the hasp is manually movable downwardly to the locked position shown in Fig. 1. actuated by a spring 48a individual thereto and that by insertion of the key 3| the tumblers automatically assume the position shown in Fig. 2.

I Hat-24a represents a plate in dotted lines which is positioned within the casing 1 ad jacent cover plate la and having openings to supportingly receive the outer ends of pins 25 and 3|.

It is believed obvious from the foregoing description and the drawing that the lock is well adapted for the service required and while the lock is useful for securing a portion of a garment between the hasp and plunger it may be used in an place where a hasp lock is serviceable.

Having thus described my invention, its utility and mode of operation, what I claim and desire Each tumbler 36' is.
