Specification of Letters Patent.

Patented Mar. 15, 1910.

Application filed October 6, 1909. Serial No. 521,287.

To all whom it may concern:

Be it known that I, JOSEPH S. Ismon, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in BagFasteners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to characters of reference marked thereon, which form a part of this specification.

My present invention has reference, generally, to improvements in looking attachments for the hinged sections of bag-frames; and, this invention relates, more particularly, to a novel construction of looking or holding device adapted to be attached di rectly upon one of the frame-sections, and the other frame-section, known as the underlap frame-section, is made with an opening or cut-away part and a holding or retaining stud or tongue-like projection, forming an integral part of said underlap frame-section, with which a looking or holding element, forming a part of the looking or holding device attached to the overlap frame-section, can be brought in retaining engagement so as to hold the two framesections in their closed relation, and that without the use of a hasp-plate and its hasp now ordinarily secured upon the said underlap frame-section.

My present invention has for its principal object to provide a neatly and simply constructed looking or holding device adapted to be attached to the overlap bag framesection, in which the usual base-plate of the casing is dispensed with, and in which the locking mechanism moves directly upon a portion of the upper face of said overlap frame-section, and in which the underlap frame-section is made with an engaging means, preferably in the form of an opening or cut-away part and a holding or retaining stud or tongue-like projection which forms an integral part of the underlap frame-section, all with a view of dispensing with the usual hasp-plate and its hasp, and to provide a closing means which is readily and quickly manipulated when it is desired to release the frame-sections from the closed or locked relation.

The invention has for its further object to provide a novel holding or looking catch from the casing or shell of which the usual closing or base-plate has been omitted, the looking or holding mechanism of which when manipulated to cause the same to assume its released or unlocked relation to the underlying frame-section, remains in such released or unlocked relation as long as the two pivoted frame-sections are open, but automatically resumes its locking relation when the underlap frame-section is moved into its closed relation with the overlap frame-section.

Other objects of this invention not at this time more particularly enumerated will be clearly understood from the following detailed description of my present invention. With the various objects of my present invention in view, the said invention con sists, primarily, in the novel holding or locking device for bag-frameshereinafter set forth, as well as in the novel construction of bag frame-sections therefor; and, the invention consists, furthermore, in the novel arrangements and combinations of the various devices and parts, as well as in the details of the construction of the same, all of which will be hereinafter more fully set forth, and then finally embodied in the clauses of the claims which are appended to and which form an essential part of this specification.

The invention is clearly illustrated in the accompanying drawings, in which Figure l is a side elevation of a pair of bagframe-sections, represented in their closed relation and one of the said closed frame-sections being provided with a looking or holding device, all representing one embodiment of the present invention; and Fig. 2 is a top edge View of the parts shown in said Fig. 1, with the handle-portions removed, and showing the frame-sections partially open. Fig. 3 is a bottom view of the two frame-sections in their closed relations; and Fig. i is a similar view of the said frame-sections represented in a partially opened or separate relation. Fig. 5 is an enlarged longitudinal vertical section of a portion of the overlap frame-section and the shell or casing of the looking or holding device, the looking or holding catch of the said device being represented in side elevation, and the said section being shown as taken on line 5-5 in Fig. (3 of the drawings, looking in the direction of the arrow w.

I so

Fig. 6 is apart plan view and part horizontal section of the parts represented in Fig. 5, said Figs. 5 and 6 showing the slid able looking or holding catch or bolt in its normal initial position. Fig. 7 is a view similar to that shown in said Fig. 6, but representing the holding or locking catch or bolt in its operated position, and held in said position by an engaging portion of the overlap framesection to permit of the opened or separated relation of the said underlap frame-section with the said overlap frame-section. Fig. 8 is a vertical crosssection, taken on line 8-8 in said Fig. 6, looking in the direction of the arrow 2 Figs. 9 and 10 are views similar to Figs. (3 and 7, respectively, showing the holding or locking device provided with a movable locking or holding catch or bolt provided with a modified form of retaining or holding post; and Fig. 11 is a vertical cross-section, taken on line 1111 in said Fig. 9, looking in the direction of the arrow .2. Fig. 12 is a top view of portions of the two framesections of a bag frame, shown in their opened relation, and illustrating in connection therewith and in top view, a lock and a haspplate and its hasp, said lock embodying some of the features of the present invention. Fig. 13 is a longitudinal vertical section, said section being taken on line 1318 in said Fig. 12; Fig. 14; is a horizontal sectional representation, taken on line 1-:l-1l-. in said Fig. 13, looking in a downward direction; and Fig. 15 is a transverse vertical section, taken on line 1515 in said Fig. 13, looking in the direction of the arrow 11., and said section being made on an enlarged scale.

Similar characters of reference are employed in all of the above described views, to indicate corresponding parts.

eferring now to the said drawings, the reference-character 1 indicates an outer or overlap frame-section, and 2 is the inner or underlap frame-section 01' a bag-frame, said frame-sections being formed with the usual leg- members 3 and 1, respectively, and being adapted to be hinged together, in the usual manner, by means of suitable pivots or pins 5, substantially in the manner represented in Figs. 1, 3 and 1 of the drawings. As shown, the said outer or overlap frame-section 1 is made with a suitably formed opening which is preferably L-shaped being thus formed by the two right-angled open portions (3 and 7, as clearly shown in Fig. 4t of the drawings. The said frame-section 1 is also made with a pair of lug-receiving openings 8 and 9, and is also formed with an attaching lug or projection, as 10, which is forced out of the metal from which the frame-section 1 is made. The inner or underlap framesection 2 is also made with an L-shaped opening formed by. the two right-angled open portions 11 and 12, so as to provide a holding or retaining lug or projection 13, the open portion 11 extending from the marginal edge-portion 1 t. of said framesection 2, substantially in the manner illustrated in said Figs. 2 and 3 of the drawings.

The frame-section engaging or holding device comprises a suitably chambered shell or casing 15 of any suitable configuration, said shell or casing being made in its one end with a slot or opening 16. Extending downwardly from the marginal edges of said shell or casing are suitably formed fastening lugs or tongues 17 which are passed through the lug-receiving openings 8 and 9 in the frame-section 1 and are bent over upon the under face of said frame-section so as to permanently secure the said chambered shell or casing 15 in its position upon the outer face of the said frame-section 1, in the manner represented in Figs. 1, 2, 1 and 5 of the drawings. Within the said shell or Ct sing 15, and slidably disposed upon the upper face of the frame-section 1, is a bolt or plate 18 which is provided at one end with a suitably bent up portion 19 formed 8 with a longitudinally extending member or element 20, the said member 20 projecting into and through the slot or opening 16 in the end of the shell or casing 15 and providing a suitable push or fingerpiece, substantially as and for the purposes to be presently more fully described. Struck or forced out of said bolt or plate 18 is a retaining or holding post 21 which extends in a downward direction from said bolt or plate, and preferably at right angles thereto. The said post 21 furthermore projects (ilownwa-rdly into and through the L-shaped opening in said outer or overlap frame-seetion 1, and under normal conditions, when the parts are in the position indicated in Figs. 5 and 6 of the drawings, and when the two frame-sections are closed, the said post is in the open portion 7, being retained in that position by a coiled spring 22 which has its one end attached to the previously mentioned attaching lug or projection 10 of the frame-section 1 and has its other end at taehed to a lug or post 23 which is connected with and extends in an upward direction from the inner end-portion of the bolt or plate 18. The tendency of this spring is to maintain said bolt or plate 18, in its normal initial position represented in F 5 and G of the drawings, with its fingerpiece projecting from the slot or opening 10 in the shell or casing 15 ready to be pushed in an inward direction by the operator. A slight push or pressure upon said fingerpiece produces a sliding move ment of the bolt or plate 18 in the direction indicated by the arrow 0 in Fig. (3, until the post 21 moves opposite the open portion 6 of said frame-section 1, whereupon owing to the diagonal arrangement of the spring 22, the bolt or plate 18 assumes the position shown in Fig. 7 of the drawings, with the said post having passed into said open portion 6 and resting therein, in the manner illustrated in Fig. at of the drawings. The two frame- sections 1 and 2 are now in their open relation and can be brought into their separated positions indicated in Figs. 2 and a of the drawings to open the bag-frame.

lVhen the inner or underlap frame-section 2 is moved into its closed relation with the outer or overlap frame-section 1, the open portion 11 in said frame-section 2 enters upon and against the post 21, still lo cated in the open portion 6 of the framesection 1, but is moved by the engaging edge 24: of said frame-section 2 directly opposite the now registering open portions 7 and 12 in the respective frame- sections 1 and 2. Immediately the tension of the distended coils of the spring 22 will cause the bolt or plate 18 to assume its normal initial position indicated in Figs. 5 and 6 of the drawings, whereby the said post 21 is moved into said open portions 7 and 12 and behind the holding or retaining lug or projection 13 of the frame-section 2, as clearly shown in Fig. 3 of the drawings. The two frame-sections are thereby held in their closed and locked relation, as will be clearly evident. It will thus be understood that as long as the two frame- sections 1 and 2 are separated or open, the parts of the holding or locking device are maintained in their unlocked or non-locking relation, but when said framesections are moved toward each other, so that the outer frame-section will lap over the inner frame-section, the two frame-sections will be held in their locked and closed positions, and that without the use of any hasp-plate and hasp, until the mechanism is again brought into its released position by an inward push upon the said finger piece 20.

Instead of providing the sliding and spring-controlled bolt or plate 18 with a retaining or holding post 21 of the general arrangement and construction hereinbefore described in connection with said Figs. 1 to 8 inclusive, a bolt or plate 25, shown in Figs. 9, 10 and 11 may be employed, said bolt or plate being made with a cutaway part 26 and with .a downwardly bent and extending postlike member 27 which is formed with a hole or opening 28 of any suitable configuration. In all other respects, the said bolt or plate 25 and the arrangements of the L-shaped openings in the two frame- sections 1 and 2 are the same as in the constructions represented in said Figs. 1 to 8 inclusive. The locking and unlocking movements of the various parts are also the same as those previously described 8X cept that, instead of the post-like member 27, in the construction represented in said Figs. 9, 10 and 11, moving behind the hold ing or retaining lug or projection 13, will move its opening or hole 28 directly in front of the free end of said lug or projection 13, the spring 22 pulling the perforated portion of said post 27 directly over the lug or projection 13, so that the parts will be held in their locked relation, as will be understood and as will be clearly seen from an inspection more particularly of Fig. 11 of the drawings.

It will thus be clearly evident, that by my present invention I have provided an etlicient and exceedingly simple holding or locking device for bag frame-sections, the parts being reduced to a minimum so that there is no likelihood of their getting out of order, and at the same time dispensing with the additional cost of manufacture by dispensing with the usual and often unsightly hasp-plate and its hasp or hasps. It will be understood, furthermore, that the framesections may be provided with one or more of the locking devices embodying the principles of my present invention, and that they may be used with any desired part or parts of the two frame- sections 1 and 2. The frame-section 1 is provided with the usual bag-frame handle, the frame-section in this case being formed with holding loops 29 which are struck up or forced out of the metal of which the frame-section is made, for the attachment to said loops of suitable rings 30 with which are connected the usual handle-loops 31, substantially as shown in Fig. 1 of the drawings.

In Figs. 12 to 15 inclusive, I have shown a lock-casing or shell, provided with a key operated mechanism, but in which the usual base-plate has been omitted, and the said casing or shell being secured by means of fastening lugs directly to one of the framesections, instead of to the base-plate and then fastening the said base-plate to theframe-section as heretofore; the construction shown in said Figs.12 to 15 inclusive showing also certain minor details embodying certain features of this invention. In the said drawings, the reference-character 32 indicates the lock-casing or shell fastened directly to the face of the outer or overlap frame-section 1, by means of fastening lugs 33 which are passed through holes or openings 34 formed in the frame-section and are bent against the under surface of said framesection, so as to permanently secure the said casing or shell in place. In one of its sides, the said casing or shell 32 is made with the usual hasp-hook receiving openings, as 35, see Figs. 14 and 15, for the entrance of the hasp-hooks 36 which extend from a haspplate 35 secured upon the other frame-see tion 2. In its upper face, the said shell or casing has a slot 37 above which slides a finger-piece 38. This fingerpiece has a portion 39 which extends through said slot 37 and is attached to the hasp-bolt 10 which is slidably arranged within said shell or casing 32, and is retained and returned into its normal initial position by means of a suitable spring 41. The bolt 1-0 is held in its locked position by means of a snip or plate 42 which oscillates upon a pin or post- -tt3 extending above the upper surface of the frame-section 1. This snip is brought into its locked and unlocked positions by means of a key which can be inserted into the keyhole ll-Lland a key-receiving post 45 and made to engage with the end-portion 16 of said snip To limit the pivotal movement of the said snip, its opposite end-portion is cut out, as at 47, so as to provide a pair of fingers or stops a8 which extend upon opposite sides of a post or projection 45) forced in an upward direction out of the said f 'ame-section 1. In order to give the proper action to the snip, when operated by means of the key in either direction, the said snip or plate 42 is made from springmetal, so as to have resiliency, a downwardly extending projection 50 being forced out of said plate d2 which is adapted to move over an upwardly extending projection 51 which is forced out of the framesection 1. By this means, every time the plate 42 is turned by means of the key, its projection 50 snaps over the projection 51 formed in the frame-section 1, so as to give a positive indication to the operator when the said snip or plate 5L2 has been brought into its locked 01' unlocked position.

I am aware that some changes may be made in the several arrangements and combinations of the various devices and parts, as well as in the details of the construction thereof, without departing from the scope of my present invention as set forth in the foregoing specification and as defined in the claims which are appended to the same.
