11 Claims.

to expel the contents of the cartridge, the cartridge thus itself forming the barrel of what may be called a calking gun.

The present invention is concerned especially with the means for engaging the far end of the cartridge and particularly with a discharge spout carried by such means and adapted to make a tight connection with the forward end of the cartridge.

In its preferred form my cartridge comprises a paper tube having an internal cap which may form a closure at one end and may act as a head for a plunger in extruding material from the other end, the latter end having a cap with a central opening through which the extrusion takes place. The device which carries the cartridge has a plate to en age its front end and a spout adjustably carried by the plate and adapted to be caused to abut the front end of the cartridge to make a tight connection therewith so that the material may be extruded through the spout without leakage.

My invention comprising the means by which I accomplish the above result is illustrated in the drawing hereof and is hereinafter more fully described.

In the drawings, Fig. 1 is a side elevation partly in section and partly broken away, of the dispensing apparatus the full-line showing of the bail and front plate indicating the idle position, and the broken lines showing these parts as they are being brought into place to engage the cartridge, which is also indicated in broken lines; Fig. 2 is a rear elevation of the dispensing apparatus; Fig. 3 is an enlarged horizontal fragmentary section through the forward portion of the handle, indicating part of the cartridge in position; Fig. 4 is a side elevation of the complete apparatus with the cartridge in place, the plunger rod being intermediately broken out and different positions thereof indicated in broken lines; Fig. 5 is a plan of the complete apparatus with the cartridge in place; Fig. 6 is an enlarged vertical section through. the front retainer pla e 2 and the adjacent portion of the cartridge, showing the parts in position immediately after the cartridge has been put in place; Fig. 7 is a similar section indicating the spout screwed in against the forward end of the cartridge, and Fig. 8 is an end elevation of the front retainer plate carrying the spout.

As shown in Figs. 1, 4 and 5, ID indicates the body of the cartridge which is a paper tube similar to a mailing tube preferably spirally wound. This cartridge carries an internal cap ll, Fig. 2, which when the cartridge is loaded lies adjacent one end thereof and forms a closure therefor. It is pushed into the cartiridge by the gun mechanism to expel the contents through a closure cap [2 at the forward end. The closure cap 12, as shown in Figs. 6 and 7 comprises a resilient disclike member having an annular portion l3 to engage the interior of the barrel H] with an out wardly extending flange 14 to abut the end of such barrel, with a final outside flange l5 clamping against the exterior of the barrel. This closure plate is provided with a central opening (6 through which the discharge takes place, the cap being annularly flanged outwardly at ll about this opening.

When the cartridge is used in the shipping container the discharge opening [5 is closed by a thin frangible seal (not shown) extending across the interior of the opening. The internal cap H at this time is at the other end and forms an effective closure for that end of the cartridge.

My skeleton gun in which such a cartridge as described may be mounted comprises a suitable handle 20 in the form of a hand grip rigidly carrying a forwardly facin cylinderical cup 2| in which the rear end of the cartridge may be mounted.

To engage and hold the forward end of the cartridge I provide a bail which is pivoted at 31 to the handle body and at its far end car ries a plate 32 adapted to engage the front end of the cartridge and hold it in position with its rear end in the cup 2|. The plate 32 has a central outwardly extending flange 33 which is internally threaded. In this thread is mounted the spout 35 which carries. external threads meshing with the internal threads of the plate. The spout has a slight annular flange 36 at its inner end limiting its outward movement when such flange engages the plate. ihe forward face of the flange 36 is conical and when the spout is completely withdrawn seats in a conical recess .in the front plate 32 to bring the extreme inner and oi he pout flush with he nner face-oi the plate, as shown in Fig. 6. This enables the plate to be slid readily across the end of the cartridge without obstruction.

The forward flange IT on the cartridge cap [2 is of such size that it may readily but snugly occupy the interior of the s out. When the cartridge is in place the spout is screwed inward manually until its end'abuts the cartridge cap [2, the spout embracing the flange H, as shown in Fig. 7. This makes a tight connection between the spout and the cartridge.

The front closure plate I 2 is resilient, enabling the spout to make a tight connection therewith, whether the spout occupies such a position as shown in Fig. '7, with its inclined end 31 facing downwardly or in the diametrically opposite position with the incline facing upwardly. Accordingly, the spout may be turned to present the incline in any direction desired and still maintain a tight connection witlrthe cartridge cap. The flange 36 and a bulge at the other end of the spout thread permanently retains the spout in the plate 32.

The front plate 32 is provided with a rear wardly extending lip 38 at its lowermost portion adapted to extend beneath the cartridge while at its upper portion it has a forwardly extending lip 39 adapted to provide a finger grip for conveniently holding the plate while the cartridge is being put in place.

The bail 30 is shown as held at its intermediate portion on the front of the plate 32 by ears 40 (Fig. 8) partially severed from the plate and overhanging the bail. The bail is intermediately looped downwardly as at 4| to clear the spout. This downward loop on the bail operates as a stop to engage the spout and limit its downward swing relative to the bail, as shown in full lines in Fig. 1.

The rear ends of the bail are shown as pivoted to the handle by having inturned portions 43 (Fig. 2) which lie between rearwardly bowed portion 44 of the side flanges 22 of the sheet metal hand grip 20 and the cup 2|. These flanges are preferably riveted to the cup by integral partially severed lugs 45 (Figs. 2 and 3).

The extreme ends of the bail are turned at an angle to extend upwardly, as shown at 46, to hold the bail in position in its pivotal anchorage. These upturned ends 46 also serve to limit the possible downward swing of the bail as shown in Fig. 1. Accordingly when the hand grip 2B is held in the users hand the bail and forward plate and spout naturally drop by gravity in some such position, as shown in full lines in Fig. 1, leaving the space in front of the handle cup 2| entirely unobstructed for the mounting of the cartridge.

In mounting the cartridge in the gun the plunger plate is withdrawn into the cup, the cartridge placed in the cup, the front plate 32 swung upwardly across the front end of the cartridge until the bottom lip 38 abuts the undermost portion of the cartridge. This movement swings the plate into position at right angles to the cartridge axis and locates the cartridge accurately with reference to the discharge spout and then the spout is manually screwed in until it abuts the front end of the cartridge and makes a tight connection therewith.

Any suitable mechanism may be provided on the handle for operating the plunger to force the contents out of the cartridge. As shown, the

hand grip 20 carries a longitudinal rod 23 having a plunger plate 24 at its forward end and-- has a an operating lever 25 for moving a spring-pressed pawl 26 (Fig. 1) to feed the rod forwardly A suitable detent pawl 21 retains the gain made in such feeding. As shown the plunger rod has teeth 28 along one edge. When the rod is turned to present these teeth upwardly (as indicated by broken lines 29 in Figs. 1 and 4) the rod may be freely withdrawn toward the right. To feed the material the rod is turned with its bent end 29 extending downwardly which places the teeth where the pawls act on them, so that the hand lever 25 may forwardly feed the rod into the cartridge.

It will be seen that my manually operated apparatus is an extremely simple and relatively inexpensive construction; that the cartridge, with a discharge opening closed by a frangible seal, may be readily mounted therein and when so mounted a complete calking gun is provided. Such gun has conveniently operable manual mechanism for extruding the material through the discharge spout, enabling use of the apparatus in the usual manner of a calking gun. The cartridge may remain in the apparatus as part of the complete gun until the material has been entirely used. Thereafter, merely rotating the spout in the direction to screw it out and withdrawing of the plunger rod will free the used cartridge and enable the installation of a fresh one.
