Patented Apr. 1, 1941 PLASTIC MATERIAL DISPENSER Vincent E. Dewees, Philadelphia, Pa., assignor to Calbar Paint & Varnish Company, Philadelphia, Pa., a corporation of Pennsylvaniay Application January 7, 1939, Serial No. 249,713
2 Claims.
This invention relates to plastic material dispensers, that is to say, to improved means for dispensing and applying plastic materials such as caulking compounds, putty, heavy greases, or the like.
More specifically considered, the invention relates to a cartridge in which the plastic material is initially placed, usually at the factory, said cartridge being adapted to be inserted in a gun of any preferred type, but with which the cartridge is coordinated.
'I'he principal object of the present invention is to provide a cartridge for plastic materials, such as caulklng compounds, putty, greases, or the like, which may be filled at the factory, and delivered to the user for use in a gun having means for applying pressure to expel the plastic material through the nozzle or other delivery member of the gun, which cartridge will be relatively inexpensive, which may be readily and conveniently inserted in the gun, and in the use of which Waste of the material will be reduced to a minimum.
Heretofore, various types of preilled cartridges or inserts have been suggested for use in guns for dispensing and applying plastic materials, but none of these have proved entirely satisfactory. Nevertheless, there is recognized need for such devices, and the saving of time of the user through the employment of such prelled cartridges or inserts is Well understood.
The present invention, therefore, contemplates the provision of a novel form of cartridge adapted to be inserted in the barrel of a dispensing gun, which is quite emcient for its intended purpose. yet is so relatively inexpensive that the same may be discarded after a single use.
The nature and characteristic features of the invention will be more readily understood from the following description, taken in connection with the accompanying drawing forming part hereof, inwhich:
Figure 1 is a View, partly in section and partly in side elevation, of a caulking gun having in place therein a cartridge or insert embodying the main features of the present invention, the same being shown with the parts in their positions after a portion of the contents of the cartridge have been expelled therefrom;
Fig. 2 is a longitudinal section of a filled cartridge or insert as the same is furnished to the user;
Fig. 3 is a perspective of a novel form of piston member employed in the'cartridge; and
Fig. 4 is an enlarged diametral section of said piston member.
Referring now more particularly to Fig. 1 of .the drawing, there is there shown a caulking gun of a more or less common type, in connection with which the cartridge of the present invention isadapted to be used.
Said gun comprises a cylindrical barrel I0, the respective ends of which are threaded, as at II and I2, for the mounting thereon of a vhandle portion I3 at one end and a nozzle portion I4 at the other end. The stock or handle portion I3 is provided with a cap member I5 which is mounted on the end of the barrel I0 by means of the threads I I above referred to.
The handle portion I3 may also'be provided with the usual grip lever I6 for actuation, through suitable mechanism (not shown), of the piston rod Il. The piston rod I1 has, at its outer end, a handle I8 for the withdrawal of the piston rod to the rearmost position after the contents of the cartridge have been discharged. The inner end of the piston rod I1 is provided with an enlarged head portion I9, which coacts with the piston portion of the cartridge, as will be hereinafter set forth.
'I'he nozzle portion I4 of the gun is also provided with a cap member 20, mounted on the end of the barrel III by means of the threads I2 hereinbefore referred to. and said cap member 20 is provided with a discharge nozzle 2l of any preferred type, which may be threaded therein, so as to be replaceable by nozzles of other types and sizes. There is also provided a resilient washer 22 at -the end of the barrel III within the cap member 2I|,for a purpose to be presently explained.
The cartridge proper comprises a cylindricalV device of such external diameter as to permit it to be inserted within the barrel I0 of the gun. The cylinder 30 of the cartridge is of such length that when it is inserted in the barrel III of the gun, and the cap members I5 and 20 at the ends thereof are screwed into place, the ends of the cylinder 30 of the cartridge will be seated at the one end against the cap member I5 and at the other end against the resilient washer 22, and thus any leakage of the material around the forward end of the cylinder 30 of the cartridge will be prevented.
The cylinder 30 of the cartridge is preferably made of a cardboard tube, similar to the well known mailing tubes, but it is lined interiorly with a material Il such as Cellophane or the like, which is permanently secured to the material of the tube and which will present a smooth interior surface,.and at the same time be impervious and chemically inert to the material contained within the cylinder. At one end of the filled cartridge, there is mounted a piston member 32 made of relatively heavy cardboard having a nat central disc portion 33 against which the head portion i3 of the piston rod i1 abuts when the gun is in use. The rim 34 of the piston member 32 is flared at a slight angle of inclination to the central disc portion 33 and the peripheral edge of the flared portion 34 of the piston member bears against the smooth interior surface provided by the lining material 3l of the tube.
For the most eiilcient results. and as shown more particularly in Figs. 3 and 4 of the drawing, the leading face of the piston member 32 has its central portion flat as at 35, and the rim portion 34 extends therefrom at an obtuse angle, preferably from a definitely defined circular line 36, while the follower face of the piston member 32 likewise has a fiat central portion 31 for engagement by the head portion i9 of the piston rod Il, from which .flat portion the surface of the rim portion 34 extends in a curved conformation as at 38.
However, the important consideration is that the peripheral edge 39 of the piston member 32, which bears against the smooth internal lining 3i of the tube, is of substantially the same thickness as that of the disc proper. When the piston member is flexed by the applied pressure, the entire peripheral edge 39 is `brought into close intimate contact with the interior surface provided by the lining material 3|, and leakage past the piston member 32 is thus obviated.
The other end of the cartridge is provided with a thin disc 40 of paper or the like. Each end of the tube is provided with a cap member 4I made of thin metal having flanges 42 extending over the outside of the tube 30 at the ends thereof.
It will be seen that the piston member 32 at one end of the cartridge will prevent the material contained therein from contacting with the cap member 4l at that end, and the paper disc 40 at the other end of the cartridge will prevent the material from contacting with the cap member 4I at that end.
When it is desired to insert the cartridge within the gun for the purpose of affording a further supply of material to the user, the piston rod I1 is retracted to the rearmost position and the nozzle cap 20 removed by unscrewing the same from the end of the barrel l of the gun. The shell of the empty cartridge which has previously been used in the gun, is then removed therefrom. The filled cartridge is then taken and the caps 42 removed from the ends thereof, and also the paper disc 40 at the end remote from the piston member 32 is also removed.
The cartridge is then inserted in the gun with the piston end toward the head of the piston rod. The nozzle cap 20 is then replaced on the end of the barrel l0 of the gun and screwed up until one end of the cartridge shell is pressed against the internal shoulder provided by the cap member l5, and the other end is pressed against the washer 22 provided in the cap member 2l at the forward end of the gun barrel.
The device is now ready for use, and the gun may then be manipulated according to the particular mechanism thereof, causing the head il at the end of the piston rod l1 to be advanced forwardly in the barrel, pushing the piston member 32 of the cartridge forward to expel the contents of the cartridge through the nozzle of the It should be noted that the piston member ol the cartridge is not of the usual form of cup members which have hereinbefore been suggested for such purposes. as it has been found that the peculiar shape of the piston member, as herein shown and described, will work much more emciently with a minimum of leakage past the same, particularly when the same ls used within a tube lined with smooth surfaced material such as Cellophane or the like.
I claim:
