PATENT GEEICE.

HIRAM STRAIT, OF COVINGTON, KENTUCKY.

IMPR'OVED LUBRICATOR.

Specification forming part f Letters Patent No. 17,118, dated April 21, 1857.

To all whom it may concern:

Be it known that I, HIEAM STRAIT, of Covington, Kenton county, Kentucky, have in vented a new and useful Oiling Machine or Apparatus; and I do hereby declare that the following is a full and definite description and illustration of the same, reference being had to the accompanying drawings, in which similar letters stand for similar parts.

Figure 1 is a perspective, and Fig. 2, avertical section of this oiling-machine, showing the relative position of its parts.

X is a cylindrical oil cup or vessel open at the top and bottom.

P is a vertical projection of its top for striking with a hammer, so as to loosen the bits of planes when they require sharpening, and It 4is a horizontal projection with several screws, zz, to fasten it to a plane-stock or j ournal-boX.

L is its lid, which may be part of the cup, or separate, and is slightly concaved to receive the oil and set down in the cylinder a piece, so as to allow the blow of a hammer on the projection P, and B is its sliding and adjustable bottom.

T is a thumbscrew th at passes freely through the lid L and screws into the bottom B, so as to raise it when turned one way and lower it when turned in a contrary direction.

To support thelid in its place and prevent the bottom from rotating with the thumbscrew, two or more guides, G G, are attached to the inside of the cup at equal distances, and the bottom is tted to receive them and slide freely either up or down. The thumb-screw may be surrounded by a spiral spring, y y, to keep the bottom always fully extended.

S is a sponge or anyvother porous and elastic material saturated with oil,or a porous bag filled with oil, interposed for pressure between the lid L and bottom B. Vhen the bottom raises, the pressure on the sponge increases, and when its falls, decreases. The oil is poured first onto the lid and then passes down into the sponge, and then its iow onto a journal or the face of 'a plane-stock is regulated by the pressure given by the thumbscrew.

This oiler is applicable to planestocks and journal-boxes. In planestocks it may be placed in front or behind the bits, or in front of the stock. Vhen let into the stock it may extend clear through to the workingface, or it may extend near to it, and then the face immediately under it may be perforated so as to allow the oil to iiow through and spread over it. The oil-cup may have a permanent and perforated bottom immediately under the sliding one, if required. When applied to journal-boxes, the lower part of the oil-cup X under the sliding bottom B may be contracted to'a small aperture, and in plancstocks expanded to their width. Any material that will saturate with oil and discharge it by pressure may be used in place of sponge.

This oiler may be attached so as to operate either vertically or horizontally. merely rest on the guides or be screwed firmly in its place.

The oil-cup may be square, oval, oblong, or of any other irregular form, and then the guides may be dispensed with and the lid rest on a projecting shoulder or points attached to the sides.

The oiler can be cast onto plancstoek and journal-boxes whenk they are cast.

What I claim in this invention, and wish to secure by Letters Patent of the United States,

The oil-cup X, with its sliding bottom B, thumb-screw T, and guides G, in combination with porous oil-bags or pieces of sponge S, or`
