BAG Loox.

Animation nlearebmary 7,1927. serial No. 166,403.

' This invention relates to improvements in locks of the type usedin connection with hand bags in which thelframe members may be yoked lby pressing them into a .closed vposition and thus held until released by .manual 1 o cross sectlon, the former being considerably operation. v

lnV such locks it has hitherto been customary to permit the release plunger to be depressed by the actionof an entering catch, thereafter rising, by reason of impelling springs, to engage and retain the catch, means being ,.provided, movable by a key, to hold'the plungerl in av raised position, thus actually locking the frame members together and preventing their separation until unlocked. b

yIt is one of the objects ofthe present invention toy provide means for retaining the release plunger in a depressed position when the bag is in an open condition, allowing it to rise only after the catcheshave been fully entered in thelock casing and are in position to Vbecome engaged therein, thus avoiding excessive and unnecessary movementby which wear is incurred.v

A further feature isin the simplification of parts employed and in the production of a lock of unusually attractive appearance `due to the absence of extending elements. t

These and analogous objects are attained by the novel design, construction and combination of simple parts hereinafter described and illustratedin the annexed drawing in which i Figure 1 is a perspective view of a portion of the sides of a conventional type of bag provided with a lock made in accordance with the invention. v

Figure 2 is a longitudinal sectional View of the look taken in a plane parallel with and below 'the' cover plate.

Figure 3 is an enlarged transverse sectional view taken in a plane passing through the lock and bag frame members. p

Figure 4 is ank inside plan view of the lock casing back plate, showing the plunger retaining spring thereon.

Figure 5 is a fragmentary top plan view, similar to Figure 2 but showing a modiication of construction.y

i In the drawing the bag covering isvdesignated by the numeral 10, the same connecting with individual frame covers 11 and 12 disposed over therespective frame elements 13 and14, both of which are of` right angular less in its dimensions to permit being closed within the other. Y f

Rigidly secured on the inner side of the frame element 13 area pair of spaced vright angled catches lcontaining openings 16. lFixed on the frame member 14 is an escutcheon 17, through the central opening of which slightly projects a plunger 18 containing ay revoluble key guide 19, the same having a slot registrable with a corresponding slot in the plunger top and through which a key may be enteredto actuate a shift plate 2O Within the lock casing the plate being pro `vided with projections which prevent the plunger from being pressed inwardly `when the plate is in one position and permit` depression of the plunger when in another position. t

The plunger 18 is surrounded by a guide 21 riveted to the top wall of a lock casing designated generally by the numeral 22, the same having flanged ends 23 to which is riveted the corresponding ends of' a back plate 24 formlng t e rear wall of the casing, these ends being rigidly secured to the vertical ele- `ment of the vframe member 14.

Formed through the front wall of the casing are openings-25 through which the catches 15 enter to engage the cani faces of keeper detents 26, slidable on'and guided by rods 27` and pressed normally upward b encircling'compression springs 2,8, the ro s being riveted yin openings Vin the bottom wall of the casing.

vThese ydetents are slidableagainst the inner surface of the front wall of the casing and are adapted to engage in the catch vopenings 16 to retain the bag sides in closed vposition; the detents normally abut the top or cover plate of the casing and are integrally connected by a plate 29 extending therebetween in which is revolubly mounted the reduced inner end of the key guide 19. y

l They sides 30 of the plunger 18 are yextended downwardly to pass through openings in the plate 29 and thereafter bent tightly over to be rigidly engaged, thus binding the plunger and detents as a unit. Thus it will be seen that when the plunger 18 is depressed the detents 26 will 'be forced down into position to release the catch loops l5 and permit the bag to be opened, and it will be obvious that the plunger is normally raised by the springs 28.

A rivet 31 passes through the upper central portion of the back plate 24: to securev against its inner side a bent flat leaf spring 32, the same being of such width as to `[ill the space between the plate 29 and topmember of the casing 22, the end portions of the spring moving forward to engage in the space at such time as the plunger is fully depressed to hold the same in its extreme lowered position until the catches 15 have been fully entered to press the ends of the spring out-wardly causing release of the plunger and detents and consequently raising these elements to their normal positions.

When so released the compression springs 28 raise the plunger and keeper detents into engaging position, thus locking the frame sides together, such locking being made positive by key shift-ing the plate 20 into position to intercept depression ofthe plunger 18.

It is to be noted that the walls of the casing are rigidly secured by integral lugs bent over at their ends as shown forming a firm and substantial structure, and that one or more of the locks may be used as desired each being independent of another.

In the modilication shown in Figure 5 a simplified construction is disclosed, avoiding the use of separate spring elements 32 and the rivet 3l entirely.

A thinner back-plate 34 of spring metal is substituted for the previously described plate 24 and extends from end to end of the lock casing to which it is secured by rivets.

The upper portion of the plate 34 is sheared to present two opposed inreaching arms 35 having incurved terminals against which thel catches 15 make contact when the bag is closed, displacing the same in the same manner and for the same purpose that the elements 32 are displaced as herein before described.

Although I have described my improvements with considerable detail and with respect to certain particular forms of'my invention, I do not desire to be limited to such details since many changes and modilications may well be made without departing from the spirit and scope of my invention in its broadest aspect. l

Having thus described my. invention, what I claim as new and desire to secure by Letters Patent, is

1. A bag lock comprising, in combination with a casing on one frame member having a spring actuated plunger, keeper detents associated therewith and catches on the other frame member engageable with said detents, means wholly within said casing to retain said plunger in a depressed position until said catches have become engaged by said detents. 2. A bag llock comprising, in combination with a casing having a slidable plunger on one frame member and a catch on the other frame member to enter said casing, a spring actuated keeper to engage said catch, said keeper being a unit with said plunger, and a spring detent on the inner rear wall of said casing to intercept said plunger when in a receded position until released by entry of said catch. n

3.v A bag lock comprising, in combination with a casing having a slidable plunger on one frame member and a catch on the other frame member to enter said casing, a pair of rods in said casing, detent catches slidable on said rods, means on said rods to normally project said detents into engaging position, means slidable longitudinally in said casing to prevent said detents fromdepression when said lock is closed, and means insaid casing to prevent operative projection of said detents when said lock is open.

4. A bag lock comprising, in combination with a casing having a slidable plunger on one frame member and a catch on the other frame member to enter said casing, a pair of rods in said casing, a plate slidable on said rods, said plunger being connected with said plate, cam faced detents formed on said plate, a key actuable shift plate movable in said casing to control the movement of the first named plate, and a flat resilient spring in said casing engageable intermediate the first named plate and the top wall of said casing.

5. A bag lock comprising, in combination with a casing having a slidable plunger on one frame member and vcatcheson the other frame member' to` enter said casing, a pair of detents slidable in said casing, a plate connecting said detents, connections between said plate and said plunger, and a fiat spring in said casing adapted to engage said plate upon depression of the same until re-entrance of the frame catch.

6. A bag lock comprising the combination with a pair of bag frame members, of looped catches on one frame member, a casing on the other frame member, adepressible plunger in said casing, a plate actuated by said plunger, said plate being normally spring pressed towards the top of said casing, detents on said plate engageable with said catches, and means on the rear wall of said casing to retain said plunger, plate and detents in a depressed position, said means being released upon entering the catches fully within the casing.

7. A bag lock comprising the combination with a pair of bag frame members, of a pair of looped catches on one fame, a casing on the other frame, a spring pressed plunger extending above the surface vof the top Wall of said casing, a detent carrying plate ixed 0n the inner end of said plunger, said detents to engage in the looped catches, and a pair of spring arms on the rear Wall of said casing to Y retain said plate, detents and plunger when the plunger has been depressed, said arms bein retracted to release the plate upon contact y the entered catches.
