SEALING MAQI INE FOB FIBER; CONTAINERS;

Application filed October 3 1324:. Serial No. 7 7,034.

'To all whom it may concern:

Be it known that I, CHARLES C. GAMM,

a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented new and useful Improvements in a Sealing Machine for Fiber Containers.

It is my object to facilitate sealing fiber containers, such as those constructed of paper or straw board or equivalent material, and at the same time to insure complete sealing.

More particularly, it is my object to provide a machine adapted to be operated to simultaneously fold, square and seal a plurality of securing flaps upon a rectangular container. This invention also includes certain other novel features of construction, which will be more fully pointed out in the following specification and claims.

Referring to the accompanying drawings, which illustrate the best form of my device at present known to me, Figure 1 is a side elevation of my improved machine showing 25 a container in place upon the form; Fig. 2 is an end view of a container of the type upon which my device is adapted to operate; Fig. 3 is a fragmentary sectional view through. the bottom of the container; Fig. 4 is a plan view of the machine with the table top and form removed; Fig. 5 is a detail end view of the pedal and associated parts; Fig. 6 is a plan view of the pedal; Fig. 7 is a plan view of the table top and form; Fig. 8 is a side elevation of the central slide and operating rod; and Fig. 9 is a detail perspective view of the clamp supporting plate, one of the bosses being broken away to show parts otherwise concealed. 4 My machine is provided with a frame having legs 10 connected by transverse members 11 and supporting a table 12. Mounted centrally upon the table 12 is a form 13 adapted to fit within a rectangular container or caddy 14 to be sealed. Formed integral with the several sides of the container 14 is a series of flaps 16 adapted to be folded over and be secured upon the bottom or outer surface of the panel 15. The form 13 has a plain upper surface adapted to support an end or bottom panel 15 of the container 14.

To simultaneously fold and seal the several flaps 16 upon the panel 15, I provide four pinerle es 1?} carried 19 1 t upper ends of arms 18. These arms 18 extend upward through apertures 19 (Fig. 7) in the table 12 and are pivotally supported beneath the table upon horizontal pins 20. As clearly shown in Fig. 1, each of the arms 18 is provided with a pair of {hubs 21 through which a pin 20 passes. Extending downward from the hubs 21, the arms 18 are provided with bifurcated lower ends 22, which are joined by pins 23 to rods 24. The rods 24: are adapted to actuate the arms 18 as hereinafter described. Substantially vertical squaring surfaces 25 are formed upon the arms 18 beneath the plates 17 for engagement with the lateral surfaces of the container 14 when in place upon the form 13.

The pins. 20 carrying the arms 18 extend through perforations in the ears 26, and said ears are formed integral with a series of sleeves or bosses 27, extending upward from a plate 28 (Figs. 1 and 9). The several sleeves 27 and plate 28 are bored to receive 'four vertical rods 29, which are fixed at neath said plate to a pedal lever 35 by a link 36. Each of the several-pairs of ears .33 are joined by one of the rods 24 with the bifurcated lower end of one of the clam arms 18. To render the lengths of the r0 s 2% adjustable, the heads, which are joined to the ends 22 of the arms 18, are made revoluble upon threaded ends 2%? of said rods, as indicated in Fig. 4.

The pedal lever 35 is pivoted at one end upon a horizontal shaft37 extending between a pair of the legs 10, and the free end 38 of said pedal is supported by a coiled tension spring 39, which is fixed at its upper end upon the bottom of the table 12. The end 38 of the lever 35 may be depressed against the action of the spring 39, and when depressed to its fullest extent, is caught by a detent 40. This detent is pivoted at 4;]. up n a ve t a p ojection 42 of the 112129 A triangular tooth on the detent 40, normally projects, so as to engage the upper surface of the pedal 35, but when the pedal is depressed, .it strikes said-tooth to swing the detent out of its path.)

O eration.

In operation, the eontainerlettobe sealed is placed upon the form 18 with the flaps 16 extended upward above the top of said form. The panel 15 is now laid upon the top of theforn lii and adhesive is applied tothe marginsofsaid-panel, or to theabutting surfaces, of the flaps 16. pedal maybe depressed to simultaneously fold,; square and, seal the several flaps 16 upon the panel 15., hen the lever 35 is depressed, the slide 32, beingconnected by the ,arms iva. andlink 86 with said lever, is

drawn downward upon the central shaft 31, carrying the nner ends of the obllque connecting rods 24; therewith. ,As the inner ends of said rods are moved downward, the lower ends, of the arn1s 18 are forced out ward topivot saidarms uponthe pins 20 andstrike the flaps lo with the inner ends of the,plat es 17. As the rods 2stapproach the horizontal, the surfaces 25 strike the lateral surfaees ofthe container 14 and square the 17 untilthe adhesive has dried or set su'lii-.

ciently to insure aproper seal As will now bereadily understood, the container 1a is releasedby striking the ,detent out of engageinent with the pedal 35 and allowing the springs ,BQ andSS) to return the arms 18 toiopen' position shown in Fig, 1.

While Lhave illustrated a machine -particularly adapted to seal a container or caddy having a substantially square end or botto1n,.,it will ,be obvious that by minor changes in form and proportions, the machine maybe adapted to seal containers of other types. Any 'such change, is consid ered, within the spirit of my invention.
