BAG- LOC K.

SPECIFICATION forming part of Letters Patent No. 437,760, dated October 7, 1890.

Application filed April 5, 1890. Serial No. 346,660. (Model.)

To @ZZ whom it may cm1/cern.'

Be it known I, FREDERICK F. INGRAM, of Detroit, in the county of Vayne and State of Michigan, have invented a new and useful Improvement in Bag-Locks, of which the following is a speciication.

.My invention relates to bag-locks, and is an improvement on the device patented to me J une 18, 1339, by United States Letters Patent No. 405,357.

The objects of my improvements areto avoid raising the locking-spindle in the operation ot' releasing the catch, to econoinize space in the direction of the height of the device, to improve the device for preventing the catch from rising with the latching-bolt, and to separate the key and hand locking mechanisms. I attain these objects in the apparatus illustrated in the accompanying drawings, in which- Figure l is a plan view. Fig. 2 is a longitudinal section. Fig. 3 is a section on the line Qc Fig. 1. Fig. 4 is a plan View, with the top of the case cut away. Fig. 5 is a plan of the key-post. Fig. 6 is a section of the keypost on the line y y, Fig. 5; and Fig. 7 is a section similar to Fig. 2, showing a modified form of the latchingbolt-locking mechanism.

Similar reference-figures refer to similar parts throughout the several views.

1 is a base-plate secured in position on the bag by rivets 2 2.

3 is a case closed at the top and sides and open at the ends and bottom, except as hereinafter specified. The case 3 is secured to the base-plate 1, said base-plate closing the bottom of said case.

4 4 is a latchingbolt of the length of the case 3 and having its ends bent upward to close the ends of said case.

13 13 13 13 are vertical guides in the case 3, in which the ends of the latching-bolt 4 reciprocate.

14 14 are lugs lifted.

The latching-bolt 4 is bent upward at its center, as shown in Fig. 2, to leave a space under it for the shank of the catch. Said bolt is of the width of the inside of the case 3 at its ends, but is cut away on one side at the raised portion of its center7 as shown in Figs. 2 and 3.

by which the bolt 4 may be 5 is an aperture of greater length than width formed through the center of the bolt 4, but extending farther upon one side of the center of said bolt than upon the other.

6 is a bell-crank lever pivoted at 10 to the latching-bolt 4 and provided with arms 7 and 3. The key-post 19 is located between the arms 7 and 3.

12 is a stud rising from the end of the arm 8, of suiiicient heightto iill the space between the lug 22 and the bolt 4 when said bolt is in its lowest position.

9 9 are notches formed in the latching-bolt 4 at the points over which the arm 7 come at the ends of its travel. The arm 7 is made of elastic material, and is provided with a downwardly-extending stud at its ends, which stud is adapted to fit into the not-ches 9 9.

15 is a spring resting at its ends upon the latching-bolt 4 and at its center against the top of the case.

16 is a spindle passing through the top of the case 3 at its center and pivoted in said case. Longitudinal motion of the spindle 16 is prevented by the head 17 at the outside end and by the lug 18 at the inner end striking against the top of the case 3.. The lug 18 is located directly over and is of the same shape as the aperture 5.

19 is a key-post pivoted in the base-plate 1 and in the top of the case 3.

20 is a slot in the key-post 19, and 2l is a slot in the top of the case 3, through which the key passes. The key-post 19 passes through an aperture in the latching-bolt 4.

. 22 is a circular lug formed around the keypost 19 just below the top of the case 3.

24 is a catch secured in place on the bag by the rivets 25.I

26 is an aperture formed through the side of the case 3 to permit the passage of the catch 24.

27 is a shoulder extending from the upper surface of the shank of the catch 24 at that part which comes directly below the lower edge of the side of the case 3 above the aperture 26, when said latch is secured in place, as shown in Fig. 3. The latching-bolt 4 rests upon the base-plate 1, and is pressed downward by the spring 15.

The operation of the above-described device is as follows: The spindle 16 is turned by IOO means of the head 17 until the lug 18 registers with the aperture in the latching-bolt 4,

as shown in Figs. 2 and 3. Vhen the catch 24 is forced into the case 3, the latching-bolt 4 is forced upward by the inclined surface of the hook at its end, the lug 18 extending into the aperture 5. When the hook on. the end of the catch 24 has passed by the latchingbolt, said bolt falls, securing the catch in place, as shown in Fig. 3. The catch is released by the operator raising the latchingbolt 4 by means of the lugs 14 14. Then the spindle 16 is turned so that the lug 18 does not register with the aperture 5, the latchingbolt 4 is prevented from rising by the lug 18 striking against its upper surface. The head 17 is marked, as by having one of the points longer than the other when in the form shown in the drawings, or by an indentation in its periphery when in a circular form. Vhen said mark comes to a certain point on the case 3, it indicates that the lug 18 is in position to register with the aperture 5.

When the head is of the radiate form shown in the drawings, the index-point is made of sufficient length to extend beyond lthe edge of the case, so thatV the position of the head 17 can be readily ascertained by the feeling.

The latching-bolt 4 may be locked by a key in the following manner: The key is inserted in the slot 2O in the key-post 19, its bit passing through a slot 21 in the top of the case. Vhen the key is turned, its bit strikes against the arm 7 of the bell-crank lever, turning said lever and bringing the lug 10 upon the other arm of said bell-crank lever under the circular lug 22 upon the key-post 19, thus preventing the latching-bolt 4 from rising. The lug 1() is thrown from under the lug 22 by the bit of the key striking against the arm 8 of said bell-crank lever. The stud upon the end of the arm 7, extending into the notches 9 9, prevents any accidental displacement of the bell-crank lever. The shoulder 27 prevents the catch 24 from following the latching-bolt 4 when said bolt is raised by striking against the side of the case 3.

A number of modified forms of the keylocking mechanism may be substituted for that shown in Figs. 2 and 4-as, for instance, that shown in Fig. 8-in which the latchingbolt 4 is locked by the downwardly-extending lug 30 being thrown over the elevated central portion of the latching-bolt 4.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is*

1. In a bag-lock in which the latching-bolt is disengaged from the catch by drawing upon said bolt, the combination of a case, a latching-bolt provided with an aperture 5, a spindle 16, pivoted in said case and extending in a direction parallel to the motion of said latching-bolt and restrained from motion inl the direction of its length, a lug 18 upon said VYtially as shown and described.
