DEVICE FOR APPLYING GRANULAR MATERIALS File@ Feb. 4; '1935 IMI d A /9 Q Wil /5/3 Patented Oct. 15, 1935 UNITED STATES PA'raN'r OFFICE DEVICE FOR APPLYING GRANULAR MATERIALS Application February 4, 1935, Serial No. 4,771
5 claims. (ci. 2211-32) The invention relates to an improvement in devices for applying granular particles and more especially finely-divided materials, such as powdered graphite, plumbago, and the like, on surfaces to be lubricated or protected by the coating of the granular material. The device of the present invention has been developed in connection with research work directed to discovering suitable means for applying graphite as a lubricant, but it will be understood, of course, that the invention is not to be restricted to the use of the device in connection with graphite, since it contains features which adapt it to applying other granular materials.
It has been proposed heretofore to provide devices or apparatus for applying graphite as a lubricant to surfaces requiring lubrication, either by the action of the conventional powder disperser, the usual powder applicators, or by the ordinary oil can, but the use of these prior devices has not proven satisfactory because no means other than the usual cap or stopper have been provided for preventing the leakage of the graphite from the nozzle of the can or applicator when vnot in use, with the result that the graphite or other granulated material has been distributed over the tools in the workmans tool chest, clothes and other articles not intended to be sprayed or covered with the granulated material. over, the devices heretofore provided for the purpose have not been arranged to apply av predetermined amount of the graphite or other lubricant or granular material at the required point. It is accordingly the object of the presentinvention to provide a device for applying graphite or other granular materials at the desired point in controlled amounts, and when the applicator is not in use positively seal it against leakage. To
this end the invention consists in the improved .applicator for granular materials hereinafter described and particularly pointed out in the appended claims.
In the accompanying drawing illustrating the preferred form of the invention, Fig, 1 is a vertical section of the improved applicator taken on the line I-I of Fig. 2; Fig. 2 is a top plan of the device shown in Fig. 1; Fig. 3 is a section taken on the line 3-3 of Fig. 1, looking in the direction of the arrows; Fig. 4 is a sectional plan looking upwardly from the middle part of Fig. 1; and Fig. 5 is a perspective view of the plug shown in section at the bottom of Fig. 1.
The improved device for applying granular ma` terials kand the like on surfaces and other points to be sprayed or covered with a granulated lubri- Morecant or other granular material, as illustrated in the drawing, comprises a reservoir IG composedl of resilient or flexible material, such as soft rubber, as shown, or thin metal. In its preferred form the reservoir I0 is barrel-shaped, having 5 bulging sides I I, a bottom I 2 and a threaded open upper end or mouth I3.- The reservoir Ill is adapted to contain the granulated material such as graphite I5, or other dry lubricant, or other granular material, which when the walls l I of 10 the reservoir I0 are pressed inwardly by the hand of the user is forced outwardly and ejected or expressed through the tubular nozzle I6 and applied in controlled amounts at the desired point.
The tubular nozzle I6 is mounted centrally in 15 a closure Il screwed into the threaded mouth I3 of the reservoir I0. The closure Il is preferably composed ot rubber, and is provided with a downwardly proJecting circular fiange I8 which overlaps the conical portion 'I9 vof the threaded mouth I3 of the reservoir,.thereby making a tight joint between the closure and the reservoir so that the contained material may not escape at this point.
The tubular nozzle I6 is shown with a curved 25 outer end 2l and a straight inner portion 22 rotatably mounted in the closure I1. The fact that the closure ll is composed of rubber assures a tight grip of the closure on the straight portion 22 of the nozzle I6 while permitting it to be 30 rotated or turned in the closure. The nozzle I6 is interchangeable, that is to say, nozzles of different lengths are adapted for use with closure l1, depending upon the point to be applied with lubricating particles or particles of other ma- 35 terial.
When a nozzle is inserted into the closure I1 the inner extremity 24 of the nozzle is seated against a washer 25 resting on the base 26 of a plug 2l inserted into the inner end or part 28 of 40 the closure which is provided with threads enabling it to be screwed into the mouth I3 of the reservoir I0.
The graphite or other granular material I5 is expressed from vthe nozzle I6 through an aper- 45 ture 30 formed in the wall of the inner end of the straight portion 22 of the nozzle. The aperture 30 has substantially the cross sectional area of the hole 3l in the nozzle. TheA innerend of 5o the straight portion 22 of the nozzle I6 is located ln a hemispherical groove 33 in the portion 28 of the closure I'I. A U-shaped spring 34 presses the inner end of the straight portion 22 ofthe nozzle I6 against the semi-circular groove in the flat 55 portionofthewalloftherecessandso holds the nozzle in operative position.
`For some purposes, the amount of particles which can be expressed through the nozzle when the aperture 30 is fully exposed to the material A in the reservoir, is not required, and so in the present device means are provided for controlling the amount of material to be admitted vto the nozzle I6 through the aperture 30. For this purpose the nozzle IG is adapted to be rotated in the closure I1 so as fully to shut off the aperture 30 against the groove in the wall 35 of the recess invention the aperture 30 is fully exposed to the recess 33. The position of the nozzle in this ligure corresponds to the position indicated at 31 in Fig. 2. When the curved outer end 2| of the nozzle is turned to a diametrically opposed position, namely, to the position indicated Aby the word shut in Fig. 2, then the groove in the wall 35 of the recess 33 fully closes the aperture 30. Intermediate openings are indicated at the points 33, 39 and 40 of Fig. 2. It is-thus seen that any controlled amount of granulated graphite or other granular material may be applied at the desired point, and that when the device is not in use the closing of the aperture 30 prevents leakage o! the material through the nozzle I6.
It is sometimes desirable to spread the dry lubricant or other particles over the surface to which it has been applied by a soft leather or felt pad, and accordingly the device of the present application is provided with a leather pad 42 mounted on the upper end of a plug 43 adapted to be inserted into the lower flanged end 44 ofthe reservoir I0. 'Ihe circular ilange M is provided with an internal shoulder l5 adapted to grip and hold the corresponding shoulder 46 of the plug 43.
.And since the ange M is composed of flexible material, like .the reservoir Ill, the insertion and removal of the plug 43 is readily accomplished.
It will be understood that the term granular material includes all divided material including the range from what is commonly known as iinely divided material to relatively coarse granular material since the device of the present application is equally adapted for applying these granular materials irrespective of their degree of subdivision. It will also be understood that the illustrated embodiment of the invention is only the preferred form, since other modifications falling within the termsl of the appended claims will readily suggest themselves to those skilled in the art, and that therefore, the invention is not to be restricted to its illustrated form but to the principle defined by the claims.
