pivoted together whereby the opening in an article may be normally maintained closed under the tension of the link units of the device and separated under applied pressure, or whereby the tendency of the closure device will be to normally maintain the article in open position under the tension of said links, means being provided to retain the same in closed position against the action of said tenf sional means; a further object being to prozo vide a closure device of the class specified which will provide a neat and finished closure for articles of various kinds and classes, maintaining a substantially air-'tight joint at the open end of the article when the device is in closed position; a further object being to provide a closure of the class specified which will operate to quickly open and close the article to which it is applied, accomplishing this result with the least amount of effort and loss of time; a further object being to provide a closure device which may be manufactured a-t a very reasonable price permitting its application to articles of various 'kinds and classes and reducing the manufacturing cost and ultimate retail price ofthe article and in many cases, producing a better product; and with these and other objects in view, the invention consists in a closure device of the class and for the purpose specified, which is simple in construction, eicient in use, and which is constructed as hereinafter described and claimed.

The invention is fully disclosed in the fol- '45 lowing specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement'are designated by suitable reference characters in each of -the views, and in which:

It will be understood that my invention ma be applicable to articles of various kinds and7 classes such for example as tobacco pouches, pocketbooks, cases, bags and the like.

To illustrate one use of the invention, I I

have shown the device applied to one of these articles, namely a tobacco'pouch; and the closure device herein disclosed constitutes an improvement on the resilient link body formj ing the subject matter'of a prior U. S. patent granted to me December 17, `1929 No. 1,739,976.

In the drawing, /10 represents a tobacco pouch of, more or less conventional form and composed of any suitable material, the upper edge of the pouch being folded inwardly and stitched as seen at 11 to form a chamber 12 within the fold and extending from one side seam 13 to the other. It is preferred that apertures 14 be formed on the mtrurned faces of the pouch adacent the side seams thereof ig. 8 of the drawing, other apertures 15 being arranged on the outer faceY of the 4ouch centrally of the opposite walls s thereo

theapertures

14 and 15 commum# catingwith the chambers 12. This structure facilitates the attachment of my Improved '-f 'closure device to the pouch,` as later described. Y

inthe comme@ shown in Figa 1 to s 10 inclusive my improved closure device consists of two spring link units 16-16a both of which are of similar construction and the description of one unit will suffice for both. Each unit consists of two rods 17 and 18 which may be tubular in form or have tubular ends 17a--18a, note Fig. 3, in which the projecting ends 19 and 20 of a coil spring 21 are adapted to be placed. The winding of the spring and the extension of the

ends

19 and 20 is such that the rods 17 and 18 of the respective links are normally held in abuttilng relation under the tension of the springs Arranged on the springs to form a nish therefor as well as a reinforcing memberand stop is a cap 22 one side wall of which is cut out as shown at 22a to limit the separation of the rods 17 and 18. The cap carries a central rivet pin 23 which is adapted to be riveted to a plate 24 arranged at the lower face of the cap after the spring has been mounted on the pin and. arranged -within said cap. This structure is clearly shown in Figs. 3, 4, and 5 of the drawing. The ends of the rods 17 and 18 are fashioned to form outwardly extending lugs 25 which are apertured to receive

pivot pins

26 and 27. The pin 26 has a reduced neck 28 adjacent its upper end whereas the pin 27 is apertured to receive va catch plate 29 adapted to be snapped onto the pin 26 in securing the separate parts of the devicetogether.

As seen in the drawing, the adjacent ends of the rods 17-18 of each unit 16-16a are pivoted together by the

pins

26 and 27 and in assembling a complete'device, each link unit is rst attached to the pouch by passing the ends of the rods l17 and 18 through the apertures 14, thus through the chambers 12 and until the projections 25 extend out through the .apertures 15 centrally of the pouch. After both units are mounted in position, the

pins

26 and 27 are secured in osition, thus completing the assemblage o the complete device. The rounded caps which,

by the way, may be ornamented in any desired manner, produce a neat and nished appearance at the top side corner portions of the pouch as clearly seen in Figs. 1 and 2 of the drawing.

In the use of the device, it will be under' stood that the open end of the pouch is normally maintained in closed position by the tension of the springs 21 at the pivoted ends of the respective units, adjacent surfaces of the rods 17 and 18 being held in abutting ref lation under this tension, with of course, the

" fabric of the pouch between said rods, thus sealing the open end of the pouch.

When it is desired to open the pouch and after the catch 29 has been released, pressure is applied to the pivoted ends of they links in the manner indicated in Fig. 2 of the drawing, the thumb of the hand engaging the pivoted end of one link unit and a finger of the hand engaging the pivoted end of the other unit; and by moving said pivoted ends together in a grip-like action, the central p0rtion of the pouch or the side walls thereof will extend laterally and in opposite direction-s in the manner shown in Fig. 2 of the drawing, to ive access to the pouch in the operation of lling a pipe. It will be understood that the release of the hand pressure will automatically operate to close the open end of the pouch and to insure maintaining the pouch in this position the catch device 29 may be employed, but the use of the latter is not absolutely necessary.

In Fig. 7 of the drawing, I have shown a slight modification which differentiates from the structure shown in Figs. 1 to 6 inclusive, simply in that the

ends

19a and 20a of the Icoil spring 21al in each spring-link unit, in-

stead of being crossed as clearly seen in Fig. 3, are extended directly from the coil to normally maintain the rods of the link units in separated relation with respect to each other, the normal position of the parts being shown in Fig. 7 of the drawing. With this construction, the pouch or other article is closed by applying pressure to opposite and normally separated walls of the article to bring the same into abutting relation, after which the catch device is moved into position to maintain the device closed, and the instant that the catch is released, the article will be automatically opened. In other words, this structure simply reverses the process disclosed inFig. 2 of the drawing and may be found to be practical and advantageous in articles of various kinds and classes.

As hereinbefore stated, my invention may lie and are apertured to receive the pivot and l rivet pin 32 on the cap 33 which encloses-the coil spring 34. The ends of the spring 34 are adapted to be placed in the tubular bores 35 and 36 of the

rods

30 and 31, and with thisconstruction, it is essential that the ends of the springs be secured to the rods as would be the case with the structure4 shown inthe other figures. With .the construction shown in Figs. 9. and 10, the

rods

30 and 31 are directly pivoted together and when the cost of the device is not an item, this would -be the preferred structure; and when the spring is not necessary or desirable, this structure would be employed.

While certain structural details ofthe device are shown in illustrating one method' of carrying the invention into effect, it will be apparent that I am not necessarily limited to the specific structures herein shown and described nor to the ilse herein illustrated and various changes in and modifications of the invention herein disclosed may be made within the scope of the appended claims without departing from the spirit of my invention or sacrificing its advantages.
