1936. L. A. MACKLANBURG APPARATUS FOR AND METHOD OF LOADING GUNS FOR DISPENSING VISCID OR SEMILIQUID MATERIALS Filed Dec. 29, 1934 INVENTOR. @[KLA/VEURE ATTORNEYS.

' UNITED STATES PATENT OFFICE APPARATUS FOR AND METHOD OF LOADING o I GUNS FOR DISPENSING VISCID 0R SEMI- LIQUID MATERIALS Louis A. Macklanburg, Oklahoma City, Okla.
Application December 29, 1934, Serial No. 759.726 6 Claims. (Cl. 206 56) My invention relates to loads or cartridges for caulking guns or other dispensing apparatus used in applying a plastic substance such as a caulking material, grease, or any semi-liquid.
At the present time it is common practice to apply caulking material and the like from a gun usually consisting substantially of a cylindrical barrel having a plunger therein for forcing the material outwardly through a suitable nozzle. The gun is loaded by suction created at the nozzle by drawing the plunger away from the nozzle end of the cylinder. The substances usually used in guns of this type are somewhat viscid and in order to load the gun not only is considerable effort required, but before the gun can be used after being loaded it must be wiped. A waste of the caulking material is not only thus occasioned, but considerable inconvenience is caused. When a caulking gun is left partially or entirely filled for any considerable period of time, the material exudes by gravity from the nozzle.
The prime object of the present invention is to provide a cartridge or load which may be placed in the gun in a single enclosed collapsible envelope and will thus eliminate the inconvenience now present in the usual type of caulking gun.
Other objects of the invention are to provide a device of this class which is new, novel, practical and of utility; which may be used with usual caulking guns without alterations in the structure of the gun; the container of which may be used as a means for cleaning the interior of the barrel; which will save the material being dispensed; the envelope of which, when empty, may be easily and quickly removed, thus permitting the immediate insertion of a new load; which will save labor now occasioned by the necessity for workmen to climb down from ladders and the like in order to refill caulking guns; and, which will be efiicient in accomplishing all the purposes for which it is intended.
My invention will permit workmen to carry with them several loads and will therefore eliminate considerable time.
With these and other objects in view as will more fully appear hereinbelow, my invention consists in the construction, novel features, and combination of parts hereinafter more fully described, pointed out in the claims hereto appended, and illustrated in the accompanying one-sheet drawing, of which,
Figure 1 is a perspective view of a usual gun for dispensing viscid or semi-liquid materials, and showing in dotted lines my improved cartridge therein;
Figure 2 is a fragmentary perspective view of the outlet end of the gun barrel with the nozzle removed, and disclosing one end of the cartridge being severed;
Figure 3 is a perspective view of the complete cartridge;
Figure 4 is a perspective view of the carton or container within which the cartridge is shipped and handled previous to its use;
Figure 5 is a fragmentary elevational section of the gun barrel disclosing the carton in use as a means for cleaning the interior thereof; and,
Figure 6 is a fragmentary side elevation of the gun, partially in section, and disclosing a cartridge therein in a partially collapsed condition.
Like characters of reference designate like parts in all the figures.
It isunderstood that various changes in the form, proportion, size, shape, weight and other details of construction, within the scope of my invention may be resorted to without departing from the spirit or broad principle of myinvention and without sacrificing any of the advantages thereof; and it is also understood that the drawing is to be interpreted as being illustrative and not restrictive.
The inventive idea involved is capable of receiving a variety of mechanical expressions one of which, for the purpose of illustrating the invention, is shown in the accompanying drawing wherein: I v
The reference numeral indicates as a whole a tubular gun barrel having a removable nozzle 0 2 at its exhaust end, and having a suitable plunger 3 therein for forcing a material outwardly through the nozzle. The plunger is mounted upon the inner end of a rod 4 the other end of which projects outwardly through the barrel and the projecting end of which is equipped with a suitable handle 5 whereby the plunger may be moved in loading the gun. A suitable trigger apparatus 6 has a lever connection with the rod and co-acts with notches l for moving the rod and the plunger for forcing material from the barrel through the nozzle.
The above described structure is usual to guns for the purposes set forth and is not claimed by me to be new.
The invention consists substantially of a cylindrical container or envelope ll] of suitable collapsible material such as paper, cellophane, or the like, and which is preferably provided with surrounding lines H of scoring for a purpose more fully set forth hereinbelow. A fiat disc l2 is preferably provided in each end of the envelope as reinforcing, and the ends of the envelope are folded, twisted or otherwise secured over the discs as illustrated by the reference numeral 20.
A carton l5 of cylindrical form and of suitable material such as paste-board, sheet metal or the like is provided for receiving the envelopes for shipment and handling, and the carton is equipped with a suitable lid IS. The closed end of the carton is provided with a through perforation H which may be temporarily closed by thin paper IS. The purpose of the perforation I! will be more fully described hereinbelow.
Operation In loading the dispensing apparatus, the rod 4 is drawn to the limit of its throw in a direction away from the nozzle; the nozzle is removed from the barrel; the container I is removed from the carton l5 and is placed in the barrel with its inner end resting against the plunger; the disc I2 at the outer end of the container, and the folded or twisted end 20 are severed by a knife and removed; and, the nozzle is replaced upon the barrel. The gun is then in condition for use.
Movement of the plunger toward the nozzle will collapse the container as the material is forced from the barrel. When the load has been discharged, the nozzle is removed; the collapsed container, which is then upon the. plunger at the discharge end of the barrel, is removed; and, the rod is pulled to the outermost end of its stroke. The gun is then in condition to receive a new load.
Should it be found that some of the material has adhered to the inner surface of the barrel, and that difficulty is therefore likely to be encountered in inserting the load. the lid I6 is removed from the carton; the carton with the load therein is inserted, open end first, into the barrel; thumb pressure, during the insertion, is exerted upon the paper l8 suflicient to break the paper and open the perforation i1; and the carton is then removed leaving the load within the barrel. The outside diameter of the carton is substantially equal to the inside diameter of the barrel and consequently the carton acts to clean the barrel by scraping the adhered material to a position against the plunger. This material is indicated by the reference numeral 2|. The opening of the perforation ll acts to prevent a suction in the barrel during the removal of the carton. 7
It has been found practical in operation, although not preferable, to eliminate the scoring lines II and also the paper l8.
From the description hereinabove it may be seen that a workman may readily carry a desired number of the loads Ill and their cartons IS in a shoulder sack, and that his gun may be easily and quickly loaded from his position upon a ladder. Also that all mess and inconvenience, as well as all waste of material usually occasioned thereby, is eliminated.
Another advantage found in packing the material in the envelopes l0 and cartons I5 is that the material may then be packed for shipment in paper boxes. This entire cost, including the cost of the envelopes, cartons, and boxes, has been found to be considerably less than the cost of the metal buckets, cans, or drums now commonly used.
Should a caulking job be completed, or a working period be ended with only a portion of a load having been used, the remainder of the load may be removed from the gun by merely removing the nozzle. No waste of material is therefore occasioned by a gun being left for a period of time in a prone position.
Obviously, the invention is susceptible of embodiment in forms other than that which is illustrated in the accompanying drawing and described herein, and applicablefor uses and purposes other than as detailed, and I therefore consider as my own all such modifications and adaptations and other uses of the form of the device herein described as fairly fall within the scope of my invention.
Having thus described my invention, what is claimed and desired to be secured by Letters Patent, is:
1. A load for apparatus of the class described, said load including a collapsible container adapted to be inserted within the apparatus, a fluidic material in the container, and a carton of semi-rigid construction for receiving the container, said carton being of a dimension which will scrape and clean the interior surface of the apparatus when inserted therein.
