4 Claims. (c1. 93-3) f This invention has to do in a generic sense with container forming mechanism.

By way of example, I have selected the tea bag art. In the manufacture of containers typified by this industry, the production of the commodity is usually on a vast scalerunning into the millions. The item of expense is manifestly important, andit is in connection with this that my invention is essentially directed. succinctly, I contemplate an economy in the gauze or other fabrics which go to make up the bags per se.

To the accomplishment of the recited object and others co-ordinate therewith, one embodiment of my invention resides in the construction and arrangement of parts hereinafter described, illustrated in the accompanying drawings and embodied in the scope of the appended claims.

In said drawings, Fig. 1 is a side elevation of a conventional type of tea ball machine, showing the application of the invention.

Fig. 2 is a plan view of a gauze blank after it v has been severed.

Fig. 3 is a similar view illustrating the contour of the blank subsequent to trimming.

Fig. 4 is a transverse View of the pattern plate and its accessories, with the lower extremity of the plunger in full lines, as taken along section l--4 of Fig. 5.

Fig. 5 is a topplan view of the pattern plate, the plunger element being in section.

Fig. 6 is a perspective view of the plate, showing the position of the gauze, after it has been partially forced into the pattern.

Fig, 7 is an elevation, partly in section, illustrating the position of the gauze as it obtains in Fig. 6, with the closing jaws added.

Fig. 8 is a similar view showing the positionof the gauze as it appears when its upper ends are just below the pattern plate.

Fig. 9 is a similar view with the upper extremities of the gauze shown just previous to their being emitted from the cone.

Fig. 10 is a similar view showing the position of the gauze as it passes from the cone and is about to be engaged by the closing jaws.

Fig. 11 is a view illustrating the gauze as it becomes initially engaged by the closing jaws.

Fig. 12 illustrates the final position of the closing jaws as the bag is closed.

Fig. 13 is a view similar to Fig. 12 showing the surplus quantity of gauze remaining after the bag has been tied, and ready for trimming, and

Fig. 14 is an elevation of the finished bag.

Referring more particularly to the drawings, 5 designates the bed of the machine with supporting legs, as 6. On top of the bed, and preferably towards one end thereof, is an upright l which sustains a horizontally disposed plate 3. Extending in line with upright l is a rod 9 having lateral yoke l0 carrying plunger tube H depending5 from hopper l2.

Plate 8, as best illustrated in Figs. 4, 5 and 6, may be square, rectangular or any other desired shape. Medially,it is cut-out to present an openi 8 ing which somewhat simulates a quatrefoil de-IO noted generally bythe reference character l3, and comprising a central opening It with equidistantally spaced arcuate foils or slots Iii-in the present instance, although the number may be varied'at will. For the sake of clarity, this quatre- 1'5 foil is styled a pattern or die.

Depending from the inner angles l6 of the walls bounding opening I l are vertical guides ll which extend to a point coincidental with the lower edges l8 of collar I9. Internally, this collar is in the form of an inverted truncated cone with walls 20 spaced from guides ll; positioned directly beneath slots I5; and being inclined and converging downwardly towards the distal ends of said guides.

Lower edge of plunger II has a ratchet-like contour with inclines 2| and projections 22, corresponding numerically to the slots in the pattern plate.

Gauze 23 is designed to pass from the roll 24 through feed-

rolls

25 and 26, and severed into blanks, as 21, by knife 28. This means, as well as the mechanism for delivering and measuring a predetermined quantity of some commodity-- shown at 29; means for closing the filled containercomprising turntable 30 carrying clamping jaws 3|; and tieing and tag afiixing apparati constitute no part of this invention, and only such parts are shown diagrammatically as will enable one skilled in the art to gain a clear understanding of the operation of my improvement.

In operation, gauze 23 is severed by knife 28 into rectangular blanks as 21. Each blank assumes a position in superposed relation to the top of plate 8, and is centered to a nicety, as illustrated in Fig. 4. As plunger ll descends. pointed projections 22 thereof engage the fabric and constrain the latter into the opening [4 and slots E5 of the pattern plate, thereby initially preforming the blank-see Fig. 6. Simultaneously,

a predetermined quantity of some commodity, for example, tea 32 (see Fig. 7) is deposited in the pocket thus formed. Plunger ll proceeding in its downward path, and the sharp, though not too sharp, serrated edges thereof still impinging against and holding the .fabric, causes the ant contour.

short ends 33 thereof to follow vertical guides l1, and the long ends 34, to traverse the inclined walls 20 of collar IS, with the result that, when the fabric reaches the position shown in Fig. 8, long ends 34 overlap and lie contiguous short ends 33. This movement is unique in that, while the plunger elementmoves in a vertical plane, and the preforming pattern remains stationary, the fabric itself is virtually subjected to a spiral movement.

The partially formed bag, exhibited in Figs. 8 and 9, continues to emergefrom collar 20 and as this operation proceeds the upper extremity of the fabric is grasped by the oppositely disposed coacting jaws 3|, mounted on the turntable 30, un-' til the neck of the bag is brought together, see illustration Fig. 12. The surplus fabric is trimmed, the blank shown in Fig. 3 illustrating the result- In this form the neck is tied with a suitable string 35, and if desired, the string may be provided with a tag 36.

Heretofore, the production of tea bags has entailed the use of fabric measuring five and oneeighth inches square. With my invention the dimensions of the fabric are reduced to four and one-half inches square, and the bag or container holds as equal amount of the commoditytea. When it is taken into consideration that containers of this type are manufactured by the millions, it will be seen that the saving thus effected is a very material one. Moreover, my improvement has the capitaladvantage of being extremely simple in construction, and requiring only a nominal outlay for its adaptation to machines already on the market.

In its broader aspects my invention comprehends the employment not only of the various means described, but of equivalent means for performing the recited functions. It is desiredto reserve the right to effect such changes as may come fairly within the scope of the appended claims.

I claim:

1. An apparatus of the class described, comprising, in combination, a plate having an opening merging into a plurality of curved slots, vertical guides depending from said plate, a unitary collar disposed beneath the plate and surrounding said guides, the inside of the collar having a continuous inclined wall, and a plunger operable through the opening.

2. An apparatus of the class described, comprising, in combination, a plate having an opening merging into a plurality of curved slots, vertical spaced guides depending from said plate, a unitary collar disposed beneath the plate and surrounding said guides, the inside of the collar having a continuous inclined Wall, converging towards the outer free terminals of said guides, and a plunger operable through the opening.

3. An apparatus of the class described, comprising, in combination, a plate having an opening merging into a plurality of curved slots, vertical guides depending from said plate, a unitary collar disposed beneath the plate and surrounding said guides, the inside of the collar having a continuous inclined wall, the lower terminals of the guides and the bottom edge of the collar being co-extensive, and a plunger operable through the opening.

4. An apparatus of the class described, comprising, in combination, a plate having an opening merging into a plurality of curved slots, vertical guides depending from said plate, a unitary collar disposed beneath the plate and surrounding said guides, the inside of the collar having a continuous inclined Wall, the lower terminals of the guides and the bottom edge of the collar being co-extensive and spaced from each other, and a plunger operable through the opening.
