BAG-FASTENEB.

Specification of Letters Patent.

Patented Apr. 22, 1919.

Application filed December 14, 1918. Serial No. 266,769.

To all whom it may concern:

Be it known that I, J OHN W. KAUTMANN, a citizen of the United States, and a resident of Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Bag-Fasteners, of which the following is a specification.

My invention is an improvement in bags, and has for its object to provide mechanism to be used in connection with bags of any character, for securely connecting the parts of the frame at the ends, that is, on opposite sides of the lock, the said mechanism comprising spring controlled catches arranged to be released by push buttons or the like outside the bag, and wherein means is provided in connection with the said mechanism for normally holding the catch in release position after it has been released until the parts of the frame are separated for the opening of the bag, the separation of the said parts releasing the restraining means for the catch and permitting the spring to function to hold the catch in normal locking position.

A further object of the invention is to provide a neat, simple and inexpensive catch which will be within the bag, thus permitting a neat finish of the bag without bulky protuberances at the ends of the frame.

In the drawings: 7

Figure 1 is a perspective view of one end of the bag provided with the improved catches;

Fig. 2 is a transverse vertical section through the catch; I

Fig. 3 is a section at right angles to Fig. 2; v

Fig. 4 is a perspective View of the catch and its operating mechanism;

Fig. 5 is a perspective View of the restraining means;

Fig. 6 is a view similar to Fig. 2, showing the catch released. I

The present embodiment of the invention is shown in connection with a bag 1 of ordinary construction, having the closing flaps at its top, which are supported by the usual metal frame, the said frame consisting of a portion or section 2 of angular construction which carries the catch, and a portion or sec tion 3 which carries the keepers for engagement by the catch. The catch is mounted in a suitable casing 4 which has flanges 5 at its ends riveted or otherwise secured to the frame part 2, and the catch comprises a bar 6 having upon its upper face a pair of upstand ng lugs 7, each lug having the face at one slde edge of the bar perpendicular, the

l(gther face dipping or inclining toward the These catch lugs are adapted to be engaged by slots in keepers 8, a keeper being provlded for each lug, and the keepers are secured to the portion 3 of the frame. The bar 6 has a pair of depending pins 9, which pass through openings in the bottom of the case 4:, and coil springs 10 encircle the pins between the bottom of the casing and the bar, the springs acting normally to force the bar upwardly.

In closing the bag, it being understood that the parts 2 and 3 of the frame are hinged together in the usual manner, the keepers at their free ends engage the inclined faces of the lugs 7 and depress the bar 6 agamst the resistance of the spring, until the lugs have entered the slots of the keepers, when the springs immediately force the bar upward and the parts of the frame are locked together.

A push button 11. is provided for releasing the catchlugs, the said button extending upwardly from the center of the bar 6, between the lugs 7, and this button passes through an opening in the horizontal portion of the angle plate to and through an openlng in an escutcheon or housing plate 12 which is secured to the top of the angle plate 2 outside of the leather covering. With this construction, to release the frame parts, downward pressure is made upon the push button, thus depressing the bar 6 and releasing the lugs 7 from. the keeper. Since the greater portion of bags have a spring lock, it will be obvious that in order to open the bag the catches must be held released while at the same time the lock is released, a somewhat troublesome operation.

Were means provided for holding the catches in release position when the bag were open, it would beneoessary to release such restraining means before the bag could be completely closed. In order to obviate this difficulty I provide means for temporarily restraining or holding the catches in re lease position until the bag is opened, that is, until the frame parts are separated, and the arrangement is such that the separation of the frame parts releases the restraining or holding means, permitting them to functime in a normal when the bag is again closed. I11 order to obtain this result I provide a plate 13 having an upstanding lug 14 at its center and having openings 15 at its ends for permitting the passage of the pins 10.

Referring especially to Fig. 2, it will be noted that the under face of the bar 6 is beveled, the said face inclining downwardly from the attached side of the part 2 toward the free side. The plate 13 rests upon this beveled face, and since the lug 1a is substantially perpendicular to the plane of the plate, it will be obvious that when the plate is held closely against the under face of the bar by the springs, it will tend to throw the lug 14 outwardly away from the adjacent face of the bar. This lug 14, when the plate is in place beneath the bar, with the pins 10 extending through the openings 15, is in position to engage between the keepers 8, as shown in Fig. 2, so that the lug does not interfere with the closing of the bag.

The keepers may be integral with the frame part 3, or they may extend in from a separate plate 16 secured to the frame part as shown in Fig. 2. In either case a web is provided between the keepers, the said web extending over the upper edge of the frame part 3 and slightly over the upper edge of the adjacent wall of the casing 4 a sufficient distance to be engaged by the lug 14 when the catch is moved into release position. With this arrangen'ient, when the .bar 6 is depressed by the push button a suflicient distance to release the catch lugs from the keepers, the lug 14 which is caused to swing outwardly away from the bar 6 as above stated, will engage beneath the web 17 and will holdthe bar with the catch lugs in release position. So long as the bag is closed, the catch lugs will be so held. The web 17 is, however, connected with the frame part 3 and moves therewith, and when the bag is opened by moving the frame parts away from each other, the lug 14; will be disengaged from the web, and the catch support ing bar 6 will move with the catches into normal position, so that it is again ready to look when the frame parts are closed. All of the catch is within the bag, it being only necessary .for the push button to protrude, and it will be obvious that the bag may be :given a very neat appearance with such construction.

ers for engaging the catch lugs supported by the other frame member, the lugs being beveled to'be depressed by the keepers'when the bag is closed, a plate mounted to I rock on the under face of the catch supporting bar and normally pressed toward the bar by the spring support of the bar, said plate having an upwardly extending lug adapted to be rocked outwardly away from the bar by the spring support of the bar when downward pressure is made upon the bar, the other frame member having a web between the keepers 'for engagement by the lug to temporarily hold the catch bar in inoperative positiom'said bar having means extending outside of the bag for operating the same. Y

In a bag, the combination with the hinged frame members, of a catch for connecting the said members, said catch comprising a spring operated latch bar carrying a catch and supported by one of the frame members, the other frame member supporting a keeper for engaging the catch, a plate 85 mounted to rock on thevbar and having an outwardly extendinglug normally pressed outwardly by the spring support ofthe latch bar and adapted to engage the other frame member to hold the latch bar depressed and releasable from the frame member by the separation of the said members, said catch being within the bag and thelatch barhav- 'ing means extending outside of the bag for operating the latch bar.

3. In a bag, the combination with .the hinged frame members,of acatch for connecting the said members, said catch comprising a spring operated latch bar carrying a catch and supported by one of the frame members, the other frame member supporting a keeper for engaging the catch, a plate mounted to rock on the bar and having an outwardly extending lug normally pressed outwardly by the spring support of the latch bar and adapted to engage the other frame member to hold the latch bar depressed and releasable from the frame member by the separation of the said members.

4. In a bag, the combination with the 110 frame members movable with respect to each other into open and closed position, of a catch for connecting the frame members,said catch comprising a catch member carried by one frame member and a keeper *carried by 115 the other frame member, the catch member being spring controlled to engage the keeper when the frame members are moved together, and 'means in connection with the catch member and movable therewith for 120 engaging the other frame member to hold the catch member in release position and releasable bythe separation of the frame members.

5. In a bag, a latch for connecting the 125 frame members comprising a'spring catch carried by one of the frame members and-engaging means for the catch carried by the other member, and meansin connection with the catch for engaging theother frame-mem- 139 her to hold the catch in release position and releasedgby the separation of the frame memberS the engagement of the restraining means for'the catch member being controlled 5 by the releasing of the catch into engaging position. v

6. Ina bag, a latch for connecting the frame members comprising a spring catch carried by one of the frame members and engaging means for the catch carried by the other member, and means in connection with the catch for engaging the other frame member to hold the catch in release position, said means being released by the separation of the frame members.
