CARTRIDGE FOR CAULKING GUNS Filed July 18, 1956 l ff INVENTOR. S24/M052. ke-WE ATTORNEY.

Patented Mar. 22, 1938 PATENT OFFICE CARTRIDGE FOR CAULKING GUNS Samuel Crewe, East Cleveland, Ohio, assignor to Maintenance Research, Ltd., Cleveland, Ohio, a limited partnership of Ohio Application July 18, 1936, Serial No. 91,438

1 Claim.

This invention relates to improvements in containers used for handling and discharging plastic grease and the like, and particularly to cartridges for caulking guns of the type referred to in my cof-pending application filed January 30, 1936, and known as Serial No. 61,534.

An object of my invention is to provide an inexpensive cartridge, or individual container for plastic grease or caulk compounds which readily iits into the barrel of a gun of the above mentioned character and which obviates the necessity oi.' lling the gun barrel from a bulk container with a spoon, spatula, or similar implement.

Other objects of my invention are to provide a cartridge of the type mentioned with a transparent closure at one end which reveals the color and character of its contents, and also with an ejector cap at the opposite endsuitable for engagement with a gunl piston so as to form a scraper for the inside surface of the cartridge and which will prevent seepage and waste of the contents behind the said piston.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing, wherein:

Figure 1 is a section of a caulking gun havingv a partially empty cartridge therein.

Figure 2 is a side section view of a cartridge containing caulk.

Figure 3 is a front end view of the cartridge.

Figure 4 is a sectional side view of the ejector cup.

Figure 5 is a rear view of the ejector cup.

In the Figure 1. of the drawing there is shown a caulking gun of a type similar to the one described and shown in my United States Patent No. 1,536,477, granted May 5, 1925, which has a cylinder or barrel Il to which is attached a. nozzle I2, and a handle I3. The handle I3, contains a ratchet mechanism similar to the one described in my United States Patent No. 1,883,767, dated October 18, 1932, which handle operates a piston I5. There is also shown a partially empty cartridge I4, within the barrel I I, and the means by which it is emptied by the piston I5.

The cartridge I4, consists o1' a cardboard, composition, or metal tube I6, cylindrical in shape and open at both ends. The inner wall of the tube I5, is iinished with 'a layer of varnish I1, so as to give the tube I6, a hard and smooth surface, and' which prevents the tube from being damaged by the ejector cup or distorted by the absorption of the oils and chemicals in the caulkins compound contained therein. Over the front end of the tube I6, there is a cap I8, which has a transparent window. The cap I8, is simply a'metal cover having a hole over which a piece of cellophane I9, or other suitable transparent material is secured. The transparent material, however, should be of such thinness and texture that it will burst open when pressure is applied from within the cartridge I4.

The caulk 20, is visible through the cap I8, and is ejected through the nozzle I2, by the forward movement of the plunger I5, when the window in the cap I8, is broken. l Over the rear end of the tube I6, there isfa closure cap 2l, which seals the cartridge before insertion into the barrel Il. 'Ihe closure cap 2|, is made of paper or similar material and is discarded when the cartridge is about to be used.

Within the cartridge I4, there is inserted an ejector cup 4, for the purpose of aiding in the removal of the entire contents of the cartridge i4, and for preventing seepage and waste of the material behind the piston I5. This ejector cup also helps to keep the inside of the gun clean at all times. The ejector cup 4, is made oi a comparatively stiff and springy material such as tin,

celluloid, or hard cardboard. It is pressed or stamped out of sheet material, has pleated sides 23, and a depressible bottom 24. When the bottom 24, of the ejector cup 4, is pressed forward or inward by the piston I5, the sides 23, of theV cup 4, will bell or flare outward and its edge will form a close contact or seal between the smooth inner wall of the tube I6, and the piston I5, so that practically all of the caulk is removed during one stroke of the piston.

Having thus described my invention it is understood that the present disclosure is illustrative only, and that changes in construction may be made without departing from the spirit and scope of the appended claim.

What I claim is:

In a caulking gun, a cartridge for retaining plastic material, consisting ot in combination, a cylindrical container having front and rear ends, the said container having a shield formed of a solid layer of varnish, a cap for sealing the front end of the container, a window breakable by pressure from within the container in the said front cap, a closure cap for sealing the rear end of the container, and an ejector cup having a ilexible bottom andarable sides co-active with a convex ca ulking gun piston whereby the plastic material in the container may be ejected.

SAMUEL canwa.
