Description: |
| Leonard L Kalish - patent attorney
The present invention relates to certain new and useful improvements in grease-guns of the lever type generally shown in my Patent No. 2,218,363, issued October 15, 1940, and it relates more particularly to a new and useful construction in the "head" of such grease-guns, namely, that part of the grease-gun which includes the high-pressure cylinder and the cap-like or cup- like socket which receives the reservoir-barrel of the grease-gun. The object of the present invention is to provide a "head" construction which will reduce the number of parts required for the construction and assembly of a "head" of the type shown in my Patent No. 2,218,363, which will reduce the cost of manufacture of same, and which will make the resultant "head" more durable and leak-proof, and which will permit of a larger intake-port into the high-pressure cylinder-bore, so as more effectively to enable the grease-gun to handle the more viscous and stringy greases and greases at the lower winter-temperature at which most greases become viscous. The present invention contemplates the fusing or welding of the steel high-pressure cylinder to the pressed-steel cup-like barrel-receiving socket, in one of several alternative forms of construction, with an inlet-port drilled or bored through the weld or fusion; such inlet-port being relatively large (compared to the transversal dimension of the cylinder block), so as to permit free intake of viscous or stringy greases. |
