be {ZaryaFJwZ/zzw ATTU RNEYS United States Patent PERFORATOR AND CONTAINER FOR PACKAGED GREASE George F. Switzer, Ponce, Puerto Rico Application October 7, 1952, Serial No. 313,427

1 Claim. Cl. 222-82) This invention relates to a dispenser for grease particularly adapted for forcing grease into fittings, such as Alemite fittings for motor vehicles, and in particular a cylindrical casing having a piercing point in combination with an outlet nipple in one end with a plunger or piston having a rod with a handle on the extended end in the opposite end and slidably mounted therein, and a grease cartridge including grease encased in a wrapper and adapted to be positioned in the casing.

The purpose of this invention is to provide a grease gun that is adapted to be refilled and operated without unnecessarily soiling the hands of the operator.

With the conventional type of grease gun it is necessary to remove a fitting on one end of the gun and fill the cylinder or body of the gun with grease from a container. By this means it is difiicult to fill the gun without soiling the hands and without wasting grease. With this thought in mind this invention contemplates a grease gun in which grease is supplied in packages or cartridges whereby it is only necessary to remove a cap at one end of the gun and place a complete cartridge of grease in the barrel of the gun.

The object of this invention is, therefore, to provide means for forming a grease gun so that grease may be supplied in cartridges and so that the cartridges may be inserted in the gun without breaking the seals or wrappers thereof.

Another object of the invention is to provide a grease gun adapted to use grease in cartridges in which means is provided in the gun for piercing Wrappers of the cartridges as the cartridges are forced by a plunger toward an outlet nipple on the end of the gun.

A further object of the invention is to provide a grease gun adapted to use packages or cartridges containing grease in which the gun is of a comparatively simple and economical construction.

With these and other objects and advantages in view the invention embodies a grease gun having a cylindrical barrel or casing with a piercing point supported by ribs in one end of the casing, With caps threaded on the ends of the casing and with a plunger shaped to correspond with the piercing point carried by a rod slidably mounted in one of said caps and adapted to be actuated by a handle on the extended end of the rod.

Other features and advantages of the invention will appear from the following description taken in connec tion with the drawing, wherein:

Figure l is a vertical section through the dispenser or gun showing the device with a fresh cartridge inserted therein.

Figure 2 is a section similar to that shown in Fig. 1 showing the gun with part of the cartridge of grease forced from the gun.

Figure 3 is a plan view showing the upper end of the gun and illustrating the gun with the handle extended from one side.

Figure 4 is an end elevational view looking toward 2,733,836 li atented Feb. 7 1956 the lower end of the gun with the cap having the outlet spout thereon removed.

Figure 5 is a view similar to that shown in Fig. 4 showing ribs of the piercing point replaced with perforations in the point thereby illustrating a modification.

Referring now to the drawing wherein like reference characters denote corresponding parts the improved grease gun or dispenser of this invention includes a barrel or casing 10 having a piercing point 11 positioned at the apex of a hollow conical shaped member 24 which is extended upwardly from an annular band 12, a cap 13 having an outlet nipple 14 extended therefrom threaded on one end of the barrel, a cap 15 having a sleeve 16 providing a bearing extended therefrom threaded on the opposite end of the barrel, a rod 17 slidably mounted in the sleeve of the cap 15 and having a conical-shaped plunger 18 on the end extended into the barrel, and a handle 19 positioned on the extended end of the rod 17.

In the design shown the barrel 10 is cylindrical and it will be understood that the barrel may be of other suitable shape in cross section. The outer surfaces of the ends of the barrel are provided with threads 20 and 21 to receive flanges 22 and 23 of the caps 13 and 15, respectively.

As previously described the piercing point 11 is positioned on the conical-shaped member 24 which is provided with slots 25 whereby ribs are formed between the slots. Therefore when the point is extended inwardly from the end of a cartridge, as indicated by the numeral 26, a Wrapper 27 thereon may be forced against the point by the plunger 13 whereby the end of the wrapper is broken and grease from the cartridge may be forced through the slots and through the outlet nipple 14. The nipple 14 is provided with threads 28 by which the nipple may be held in grease fittings and the like.

The cap 15 which is threaded on the opposite end of the barrel is provided with vents 29 to relieve suction in the upper end of the barrel as the plunger 18 moves downwardly.

The plunger 18 is provided with a flange 3t} and an annular rim 31, L-shaped in cross section and having a sealing Washer 32 therein secured to the flange 30 with screws 33. With the plunger formed, as illustrated in Figs. 1 and 2 the piercing point 11 nests in a cavity 34 in the plunger whereby substantially all grease in the cartridge or package is used from the package.

In the design illustrated in Fig. 5 a piercing point 35, similar to the point 11 is extended from an end 36 of a casing or barrel, similar to the barrel 10, and the point is provided with perforations 37, instead of the slots 25.

With the parts formed in this manner the cap 15 with the plunger 18 is removed from the barrel or casing of the gun whereby the wrapper of a grease cartridge positioned in the barrel may be removed. With the former cartridge removed a fresh cartridge, as shown in Fig. 1 is inserted in the barrel and the plunger and cap replaced. By forcing the handle 19 downwardly the plunger forces the grease cartridge against the piercing point 11 whereby the end of the package is broken and grease may be forced through the nipple 14.

It will be understood that modifications, within the scope of the appended claim, may be made in the design and arrangement of the parts without departing from the spirit of the invention.

What is claimed is:

In a grease dispenser, the combination which comprises an elongated cylindrical casing, the outer surfaces of the ends of which are threaded, a hollow conical-shaped section having a piercing point on the vertex and an annular band at the base thereof for centering the section in the casing extended into the casing from one end thereof with the peripheral edge of the band in engagement with the wall of the casing, said conical-shaped section having openings therethrough, a first cap having an outlet nipple extended therefrom threaded on the end of the casingin which the conical-shaped section isipo'si tioned, a second cap having a sleeve providing a bearing extended therefrom threaded'on the end of the easing opposite to the end in which the conical-shaped section is positioned, a rod extended through the sleeve of the second cap, a plunger carried by the end of the rod positioned in the casing, a handle on the outer end of the rod, said plunger having a cavity therein with the cavity congruently shaped to receive said conical-shaped section, and a grease cartridge positioned in the casing, said cartridge including grease adapted to be dispensed through said openings and said nipple, when the wrapper of the cartridge is pierced by coaction of said plunger and said conical shaped section.
