LOOK FOR BAG-FRAMES AND THE LIKE.

Specification of Letters Patent.

Patented Oct. 17, 1911.

Application filed June 15, 1911. Serial No. 633,340.

To all whom it may concern:

- erence being had to the accompanying drawings, and to figures of reference marked thereon, which form a part of this specification.

This invention relates to a lock that is adapted for use under different conditions, but is particularly designed to be used as a lock for bag-frames and the like, and particularly for the type of bag known as the English traveling bag.

The lock consists of a casing in which there is a sliding latch which hasmeans to receive and engage the hasp of the lock, the sliding member being locked against any sliding movement by a latch-plate, and between the latch-plate and the latch is a spring bearing on both and having the double function of holding the latch in its normal position and forcing the latclrplate in engagement with a locking-plate, which locking-plate is held by the latch-plate in its locked or unlocked position, being operated by a key which passes in the usual way down through the loclccasing and engages the locking-plate to slide it. Thelockingplate has a stem thereon which acts as a guide for the key and also as a bearing therefor.

Another object of the invention is to provide the locking-plate and the latch-plate with co-acting means to positively and securely lock them in their relative positions, but at the same time permit their easy movement by means of the key when it is desired to change their relative positions.

The invention is illustrated in the accompanying drawing, in which- Figure 1 is a perspective view of a part of the bag-frame with the lock and the hasp slightly separated. Fig. 2 is a back view of the lock. Fig. 3 is a similar view showing the latchplate slid down to the position where it releases the hasp. Fig. 4 is a perspective view of the latch. Fig. 5 is a perspective view of the locking-plate, and Fig. 7 7

6 is a perspective view of the latch-plate.

The invention consists of a casing 10 which is inserted down through the top horizontal part 11 of one of the swinging members of the bag-frame, the casing 10 having an open side which is closed, when the lock is in place, by the vertical part 12 of the bag-frame, the casing having an escutcheon plate 13 projecting beyond the vertical sides of the casing 10 and either attached thereto or integral therewith, this escutcheon plate being adapted to be fitted against the horizontal plate 11 of the bag-frame and form a finish for the lock and the bagframe. The bag-frame is provided on its side edges with fingers 14 which act as guides and retaining means for the studs 15 which fit within the side walls 16 of the casing and bear thereon and are at tached to or a part of the latch 17 which extends across the casing from one side to the other having the noses 18, which noses are adapted to be normally in position across the openings 19 in the front of the casing, and being rounded to permit their being depressed when they are engaged by the ends of the hasps QO'which have perforations 21, which perforations 21 go over the noses 18 and lock the bag- frame members 22 and 11 together. The latch 17 has a bridge'23 which engages the top edge of the casing 10 when the latch is in its normal position, and thereby limits the movement of the latch. The bridge 23 is provided with slots 2 1 which receive the tongues 25 of a ferrule 26, which ferrule acts both as a finger-piece, as shown in Fig. 3, when it is desired to uncatch the lock, and ,is provided with a keyhole slot 27 whereby it is adapted to act as a key-casing, the key 28 being inserted through the key-hole slot 27, and the key being recessed on the inside is further guided by the post 29, which post extends from the latch up through a key-hole slot 30 in the bridge and therefore acts toguide the key until its end engages the portion 81 of the latch. In Fig. 2 the bottom part of the key is shown dotted so as not to confuse the drawing.

The latch is normally free to slide and is held up by a spring 32, which is preferably a flat leaf spring, bearing on the under side of the latch and also bearing on a latchplate 33 which has a perforation 34 fitting over a stud 35, thereby being held against any sliding movement, but being adapted to have a vertical movement, the spring thereby tending to normally force the latch up and the latch-plate down. The latclrplat'e on each end is provided with a double set of V-shaped projections 36, which V-shaped projections are adapted to fit over inverted V-shaped projections 37 of the locking-plate 38, the locking-plate 38 being adapted to slide on the bottom of the casing, having a slot 39 which fits over the stud The locking-plate 38 slides longitudinally of the casing, that is at right angles to the sliding motion of the latch, and has a vertical plate 40 attached thereto, being preferably made integral therewith and stamped up from sheet metal, the vertical plate having a slot 41 which is engaged by the tongue of a key whereby the lockingplate is slid to its locked or unlocked position.

WVhen the locking-plate is moved by the key to the position shown in Fig. 2, the nose 42 engages the bottom of the latch adjacent to one side of the bridge, and the nose 43 engages the bottom edge of the latch, these two noses thus effectually locking the latch against any movement, and when the hasps 20 are over the noses 18 the members of the bag-frame can not be separated and the bag is locked. When the locking-plate 38 is slid to its other limit of movement, that is in the position opposite to that shown in Fig. 2, the nose 42 is underneath the portion 31 of the bridge which is slightly narrower than the main portion of the latch 17, and the nose 43 is then underneath the recess 44; which is cut in the latch so that the latch can he slid down, not coming in contact with the noses 42 and 43, against the pressure of the spring 32 and the noses 18 are thus drawn down beyond the openings 19 and the hasps can be withdrawn from the lock and the bag thus opened.

To positively lock the lockingplate in its locked and unlocked positions, the V-shaped and the inverted V-shaped projections on the latch-plate and the locking-plate, respectively, engage each other, as shown in Figs. 2 and 3, to prevent any sliding of the locking-plate by jarring the bag or any other accidental method, but at the same time provide an easy bearing for the locking-plate when it is slid by the key, the inclined faces of the projections 36 and 37 permitting the latch-plate to ride over the locking-plate easily, the spring 32 forcing the latch-plate continuously toward the locking-plate, and after the projections have moved on each other far enough to get over the high points on the projections, the spring snaps the locking-plate to its position so that the locking-plate is assured of being either in its locked or unlocked position as it is forced by the spring in one direction or the other,

due to the inclined faces of the projections 36' and 37. The spring 32 is held in place by having a perforation therein which fits over the stud 35.

The operation of the locking-plate is by a simple tongue on a key which engages the slot tl, and according to which direction the key is turned, the locking-plate is either slid to its locked or unlocked position. The projections 36 and 37 can be disposed at separated points on the latch-plate and the locking-plate respectively, but I prefer to arrange them as shown, that is, a double set of projections being arranged adjacent to each other on each end of the latch-plate, and a double set near each end of the locking-plate to register with those on the latchplate.
