GREASE-GUN.
messes.
To all whom it may concern:
Be it known that I, ltonmrr JV. Knniina, citizen of the United States, residing atE-ast Sleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Grease-Guns, of which the following is a specification.
This invention relates to grease guns commonly used for the purpose of forcing a quantity of grease into gear casings, such as an automobile ditierential or the like.
The object of the invention is to provide an improved grease gun which can be readily charged with the lubricating material, by means of openings in the sides of twotele scoping tubes which form the barrel of the device, the construction being such that the tubes can be readily puttogether or taken apart, or turned to open or close the openings througl'i which the material is introduced.
The invention is illustrated in the accompanying drawings in which,
Figure l is a plan view of the device. Fig. E2 is a perspectiveof one member of the barrei. Fig. 3 is a perspective of the other member. Fig. 1 is a longitudinal section. Fig. 5 is a cross section.
Referring specifically to the drawings, the barrel of the device is composed of two tubular parts, the outer one or which is indicated at 6, and the inner one at '7. T he part 6 is split along its entire length as indicated at 8, the edges of the sp lit being spaced apart. This member is fastened at its rear end to and Within the flange of a cupped cap 3 having a opening" through which Works the rod carrying the piston 11. The other tubuis also split from one end to the other as indicated at 12, the split being widened or' enlarged for the greater part of The front end of this member is fixed in a front cupped cap M, which has a. delivery spout projeeting forwardly therefrom. The tube is spaced slightl y from the inner surface of the wall or flange of the cap 14, as indicated at 16, this space being; wide enough to receive, at a snug tit, the front end of the shell 6.
Application filed April 2, 1915.
Serial No. 18,793.
The caps 9 and 1% are provided with projections 17 which may be grasped to turn the tubes with respect to each other.
When the tubes are telescoped, with the tube 7 within the tube 6, a barrel is formed to contain the grease. By turning the tubes until the openings 8 and 13 register with each other the barrel can be readily filled with the material, and then the tubes are turned half around, whereby the openings closed and a complete barrel is formed, from which the material may be ejected by pressing the piston 11 forwardly.
The inner tube? is so constructed that it expands to tight contact against the outer tube 6. This action is permitted by the split 12 in the tube, and theresult is to prevent grease from oozing or leaking around and out between the tubes. When pressure is applied to the pistonthe inner tube is expanded to close contact with the outer tube, preventing the leakage referred to. The two members of the barrel can be readily pulled apart to remove the piston or for other purposes. Expansion of the outer tube 6 under pressure is prevented by the fact that one end thereof fits snugly within the cap 9 to Which it is fastened and the other end thereof iits snugly within the other cap 14, but as stated the inner tube is free tov expand slightly to form a ti gzht joint.
What I claim as new is:
A grease gun comprising two end caps, an inner split tube secured to one cap and having an opening in the side thereof, an outer split tube secured at one end to the other cap and fitting at its other end in the first mentioned cap and having a side opening which may be registered with the opening in the inner tube, a spout extending; from the first mentioned cap, and a piston in the inner tube having a rod extending through the other cap.
in testimony whereof, I ailix my signature in presence of two witnesses. 7
