Patented Jan. 30, 1945 JEWELRY LOCK Henry Hattenrath, Brooklyn, N. Y., assgnor to Artistic Silver Craft, Inc., New York, N. Y., a. corporation ofNew York I y Application July s i943,` serial No; 493,928 .s olaims. (cien-23o) This invention relates .to a jewelry lock and -f more particularly to the type of lock adapted to be used on bracelets and necklaces and similar articles.

An object of this invention is to provide a twothe lock would still not become disengaged. A,

further .object of the invention is to provide a lock which will be relatively simple to manufacture and assemble but which nevertheless will be positive in its action.` Other objects and advantages of my lock will become apparent as the description proceeds.

In the accompanying drawing,

Fig. l is a top plan view of a lock embodying my invention.

Fig. 2 is a side view of my lock.

` Fig. 3 is a top View partly in cross section taken on the line 3 3 of Fig. 2.

Fig. 4 is a cross sectional view taken on the line Fig. 5 is a perspective view of the top of the lock without the bottom plate.

Fig. 6 is a perspective view of the male portion of the lock.

Fig. '7 is a plan view showing the blanks from which my lock is made.

As is apparent from Fig. 7, my lock I0 is made of three pieces including a cap member a plate I2 for the cap member which forms with the cap member the female portion of the lock and a spring member I4 which forms the male portion of the lock. The cap member |I is provided with a back tab I5, side tabs I6 and |'I and a pair of front tabs I8 and I9 adapted to be folded downward to form the cap. The tab I6 is provided with a cut out portion 20,' and a similar cut out portion 2| is provided in the tab I1 to engage the

lugs

22 and 23 of the plate I2. 'I'he side tab Il is also cut away at 24 for a purpose which will be discussed later. In assembly tabs 5, I6 andll are bent downwardly as are the lugs I8 and I9 and the top I I is fastened to the plate I 2 with the

lugs

22 and 23 engaging the cutout portions 2|) and 2|. Plate I2 may be fastened to the top H by pressure, soldering or otherwise. It may be seen that when the tabs are folded into position as shown in Fig. 5, the opening 24 provides a'side entrance intolthe female part of the housing 25. Plate I4 is bent upon itself to form a catch having a lateral spring bead 30, and a spring catch 35' adjacent to the edges 3| and 32,

When the lock is assembled, it may be seen that the cut away portion 24 forms a side opening into which the spring bead 30 may be slid laterally through the opening 24 behind the tabs I8 and I9. The member I4 may then be pushed inwardly into the cap until the edges 3| and 32 are engaged by the tabs I8 and I9. Inorder to open the lock it is necessary to depress the catch 35 until the edges 3| and 32 clear` the tabs I8 and I9 and the member I4 may be pulled outwardly until the spring bead 30 engages the tabs I8 and I9. Since at this point the spring member is considerably depressed, there is quite a bit of friction and considerable pressure is needed to cause the bead to slide outwardly through the opening 24. It willv one side adjacent one of said lugs and a spring-- catch having engaging surfaces at one end thereof and a bead at the other end thereof, said bead being of asize adapted to pass through said side opening behind said lugs whereby the spring catch may be pushed into said housing until the engaging surfaces are locked behind said lugs.

2. A locking unit comprising a housing and a spring catch adapted to engage within said housing, said housing being formed of two pieces, a top and plate, said plate having lugs adapted to engage cut out portions in said top, said top havving depending lugs forming with said plate a pair of narrow slots, an opening in the side of said housing adjacent one of said slots, said spring catch being formed with a beadl and with engaging edges whereby said bead may be passed in one direction through said opening into said housing and` then at right angles thereto to position said engaging edgesbehind said lugs.

3. A jewelry lock or the like including a housing and a spring catch, means .for positioning said. catch in said housing to prevent lengthwise movement thereof and additional means to prevent the removal of said catch from said housing except through lateral movement.

4. A locking unit comprisingv a housing and a spring catch adapted to engage within said housing, said housing being formed of two pieces, a top and a bottom plate, said top having side.and

back walls, and a pair of depending lugs at the behind said lugs, and said catch may be slid into y said housing until the engaging edges pass under and behind said lugs.

5. A locking unit comprising a housing and a spring catch adapted to engage within said housing, said housing being formed with a bottom, top and side walls, a pair of depending lugs at the front thereof forming with said bottom a narrow slot, an opening in one of the side walls imme-v diately behind said lugs, said spring catch being formed withV a bead at its outer end approximateiy the size of said opening whereby said bead may be moved laterally through said opening into said housing, and a pair of engaging surfaces adapted to engage behind said lugs when said spring catch is pushed into said housing.`

6. A locking unit comprising a housing and a spring catch adapted to be engaged within said housing, said housing being formed with two pieces, a top bent upon itself to form top and side walls, said top having a pailof depending lugs at the front thereof, said plate having lugs adapted to engage cutout portions of said top,

, an opening in one of said sides adjacent said lugs forming with said lugs and said plate a narrow opening, said spring catch being formed'with a bead at its outer end and engaging surfaces at its inner end, said bead being of a size to pass through said opening behind said lugs whereby said spring catch may be pushed into said housing to engage said engaging surfaces of said catch behind said lugs.
