Specification of Letters Patent.

Application filed March 27, 1914. Serial no. 827,564.

To all whom it may concern:

Be it known that I, FRANZ A. FULLER, a citizen of the United States, residing in the city of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Bag-Fasteners, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it pertains to make, construct, and use the same, reference being had to the accompanying drawings, and to numerals of reference marked thereon, forming a part of this specification.

The object of my invention is to simplify the structure of a bag fastener, so as to render the same positive, yet effective in operation, simple in construction, and durable in use.

In carrying out my invention, make use of the structures illustrated in the accompanying drawings, in which- Figure 1 represents a side elevation of a portion of a bag frame, having a pair of abutting frame sections and provided with a bag fastener embodying the principles of the present invention. Fig. 2 represents a central vertical section on line a1'a2 of Fig. 1, showing the holding catch of the fastener upon the one frame section in its locked or holding engagement with the holding lug or post upon the other frame section. Fig.

3 represents a similar sectional view of the said parts, but showing the said holding catch and post or lug in their disengaged re-. lati-on to permit of the separation or open ing of the two frame sections. Fig. 4 represents a side elevation, partly in section, of the chambered case. Fig. 5 represents an end view of the same. Figs. '6 and 7 represent respectively, plan and side views of the supporting base. Fig. 8 represents a central vertical section of the supporting base taken on line :0a2 of Fig. 7; and Fig. 9 represents a partial longitudinal central section of the bag fastener in its assembled position.

Similar numerals of reference refer to like parts throughout the specification and draw- 1 ings.

In the structure illustrated,'I make use of but four separate parts, namely, the chain; bered case, the spiral spring, the pintle, and the supporting base upon which they are mounted. The supporting base 1 which may be of any desired form or configuration, is rigidly secured, by means of the rivets 2, to one of the bag frame members as 3. The front central portion of the supporting base 1 is recessed or cut away as at 4, to eceive a holding projection or post :3

upon the bag frame member 6, so that when provide two apertured upwardly projecting end lugs 7, said end lugs being provided with apertures 11 for the reception of the pintle 8, and by means of which the chainbered case 9 is p'ivotally connected-to the supporting base 1. The supporting base 1 is further provided with a rear wall or stop 10, extending upwardly from the base along the rear edge thereof'and between the end lugs 7 and preferably of less height than-the end lugs 7. The end walls of the chambered case 9 are apertured as at 21, through which apertures 21 the .pintle 8 passes.

The front wall of the chambered case is provided with a centrally-arranged pressedout holding portion 12 corresponding with the centrally-arranged cut-away or recessed portion .4 of the supporting base, to receive the projection or post 5 upon the bag frame member 6, to firmly secure the bag frame inembersin locked position. j

13 represents any convenient form of finger piece, which is secured to the top of the chambered case by means of a pair of integral tongues 14 inserted through apertures in the case 9, and clenched over in any suitable or convenient manner. One of the endwalls of the chambered case is provided with an integral lug or clip 15 extending in wardly from the end wall as clearly indicated, to receive one end of the spiral spring 16 to be hereinafter described. One end of the spiral spring 16 is provided with a turned-over extension 17, which rests upon the integral hook or clip, and the other end of whichpasses through an aperture 18 conveniently located in the supporting .base '1 forthe purpose of giving return movement to the chambered case, after said chambered case has been forced over into one position by the manipulation of the finger piece 13. The pintle 8 which passes through the spiral spring 16 also serves the purpose of positioning the spring.

From an inspection of Fig. 3 of the drawings, it will be seen that the rear wall of the chambered case 9 contacts with the rear wall or stop 10 which extends upwardly from the supporting base 1 along the rear edge thereof, when the catch or chambered case 9 is raised, so that the upward movement of the catch or chambered case is limited by the rear wall or stop 10 formed on the support ing base.

From an inspection of Fig. 9 of the drawings, it will be seen that the aperturedendwalls of the chambered case 9 rest upon the supporting base and in such a manner, as to prevent the fastener from being pressed too far in a downward direction, thereby reducing the possibility of injuring the fastener to a minimum by any downward movement thereof.

The front wall of the chambered case, as seen in Fig. 5 of the drawings, extends a trifle below the rear and end walls of said casing, so that when the parts, namely, the supporting base and the chambered case are assembled, the under side of the front wall of the chambered case is flush with the under side of the supporting base, as clearly indicated in Figs. 1 and 2 of the drawings.

It will thus be seen that the rear wall or stop 10 which extends upwardly from the supporting base 1, acts as a stop to limit the upward movement of the chambered case, and that the end walls of the chambered case resting upon the supporting base 1 as clearly seen in Fig. 9 of the drawings, acts as a stop to limit the downward movement of the chambered case.

The parts as constructed, simplify the structure of a bagfastener, so as to render the same positive, yet effective in operation, simple in construction and durable in use.

Experience has demonstrated that the organization above described, is a highly eiiicient one, and while the device shown and described, is the preferred embodiment of my present invention, I do not wish to be limited to the exact details of construction and combination herein set forth, it being obvious that minor variations thereof not involving the exercise of invention, may be made by any one skilled in the art, and such departures from what is herein shown and described, not involving invention, I consider within the scope and terms of my claims.

I claim:

1. In a bag frame, the combination with a pair of hinged frame sections, a supporting base secured to one of said frame sections, said base provided with a stop along one edge thereof, and aperturcd end lugs, a spring-actuated catch secured to said supporting base and in normal retaining contact with one of said frame members, said catch comprising a chambered case provided with apertured end walls, said end walls being lower than the front wall of said chambered case and adapted to bear upon the supporting base, so as to limit the downward movement of the catch, a pintle connecting the base and case, and a spiral spring surrounding said pintle, one end of which is connected to the case and the other end connected to the base, so that the rear wall of the case strikes the stop on the base when the catch is raised, so as to limit the forward movement of the same.

2. In a bag frame, the combination of a pair of hinged frame sections, a supporting base secured in alineinent upon one of said frame sections, said base provided with a stop arranged along one edge thereof, and aperturcd end lugs, a spring actuated catch pivotally secured. to said supporting base and in normal retaining contact with one of said frame members, said catch comprising a chambered case provided with aperturcd end walls, a pintle connecting the base and case and a spiral spring surrounding said pintle, one end of which is connected to the case and the other end connected to the base, so that the rear wall of the catch strikes the stop on the base when the catch is raised, so as to limit the upward movement of the same.

3. In a bag frame, the combination with a pair of hinged frame sections, a supporting base secured to one of said frame sections, said base being provided with upwardly extending aperturcd lugs and further provided with an upwardly projecting stop extending between said lugs, a spring-actuated catch in pivotal engagement with said supporting base, one end of the spring being secured to the catch and the other end secured to the supporting base, so that the rear wall of the catch strikes the stop on the supporting base when the case is raised, so as to limit the upward movement of the same.

This specification signed and witnessed this 25th day of March, 1914-.
