Description
UNITED STATES PATENT OEEICE.
ELIPHALET S. SORIPTURE, OF SYRAOUSE, NEW YORK.
IMPROVEMENT IN OILFEEDERS.
i Specification forming part of Letters Patent No. 3.952, dated March 15, 1845.
provement in Oil-Cans, Ste., which I denominate the Pneumatic Oiler77 or Syringe 5 and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which make a part of the saine7 in which- Figure l is an outside view. Fig. 2 is a vertical section through the center.
I form my oil-can, c, conical, as shown in Fig. 1, with a small tube, b, projecting from the apex thereof, and anopening, c, in the side to ll it through, which can be stopped airtight, as in the figure; or it may be of any convenient shape, such as is used in oiling machinery, or syringe-formed. In the interior ofthe can, as above described, a spiral spring is put, as represented at d in Fig. 2. This is fastened by any convenient mode to the bottom, and bea-rs against the apex of the cone above named, so as to press the bottom out as far as the tin or other thin substance of which it is formed will allow.
The .operation of the 'above-described instrument is as follows: When lled and the aperture c is stopped, if itis turned with the.
tube b downward, none of the oil or other liquid will escape; but if a pressure is applied to the bottom sufficient to force it inward, some l of the oil will be forced our in such quantities as are required, and when the pressure is removed there is an equivalent amount of air drawn up, caused by the spring d forcing out the bottom, and causing a vacuum within. This may be repeated as long` as the oil lasts. It will be obvious that other springs might be used; but I prefer the spiral one.
What I claim in the above-described instrument, and desire to secure by Letters Patent, is-
The combination of the spring with the oilcan or syringe, substantially in the manner, and for the purpose above described.
