JESSE SCHMIDT, 0F TRACY, CALIFORNIA.

SAW-OILER.

Application filed April 12, 1919.

To all whom it may concern.'

Be it known that I, JEssn SCHMIDT, a citizen of the United States, and a resident of Tracy, in the county of San Joaquin and State of California, have invented certain new and useful Improvements in Sawilers, of which the following is a specification.

My invention relates to saw oilers.

An important object of my invention is to provide a saw oiler which may be conveniently carried on the person, and by which the lubricant may be easily, quickly, and cleanly applied.

Another important object is to provide in combination with a device of this kind means adapted to house and protect the lubricant applying means and to effect saturation of the lubricant applying means as desired.

Other objects and advantages will appear as the description proceeds, and reference is had to the drawings forn'ling part of this specification and in which* Figure 1 is a perspective View of the device as it appears when not in use,

Fig. 2 is a sectional View, parts being broken away for the sake of illustration,

Fig. 3 is a vertical transverse section taken on line 3--3 of Fig. 2 and looking in the direction of the arrow.

Referring to the drawings, the immoral 5 indicates a container adapted to house the lubricant applying means hereinafter described. The container is preferably of rectangular cross section having a plane base and side walls perpendicular to the base, the opposite side walls being parallel to each other throughout. It may be constructed of any suitable sheet metal, such as tin, or any suitable fibrous materials; and is preferably of a size adapted to be carried on the person.

rIhe lubricant applying means includes a shell indicated generally by 6 preferably also of rectangular cross section, having its inner end open, as shown in the drawings. The opposite side walls S of the shell prefer ably those of greatest extent, are parallel throughout. The other pair of opposite side walls 9 are parallel adjacent the closed end 7 and remain so for a portion of their length. They then gradually taper inwardly toward the open end of the shell so as to gradually reduce the cross sectional area of Specification of Letters Patent.

the shell toward the open end thereof, and thereby contract said open end.

A block of felt or other suitable absorbent material 10 is secured in the shell. The dimensions of the block 10 are such that when assembling the device, it is necessary to compress the block in order to insert it in the shell. Vithin the shell the block, due to its elasticity expands and presses against the inner walls of the shell. This frictional engagement together with the action of the contracted inner end of the shelll serves to eifectually secure the block in its proper position.

The portion 11 of the block 10 extends from the shell and constitutes a swab or brush for contact with the surface or object to be lubricated.

A handle 1Q preferably formed of wire is disposed on the exterior wall of the outer end of the shell as shown in the drawings, and is secured thereto in any desired manner, as by soldering.

lVhen not in use, the shell 6 is housed in the container 5, the swab or brush 11 being disposed adjacent the bottom of the container.

The bottom and inner side walls of the container 5 together with the inner end of the shell 6 define a chamber 13. The block 10 is of course saturated with lubricant. However, when the block has become dry from use, a quantity of lubricant is placed in the chamber 13 and the shell G is inserted so that the swab 11 is slightly immersed in the lubricant as shown in Fig. 2 of the drawings. The lubricant will then be absorbed with the block by capillary action until the block is saturated.

In use, the shell G is gripped by the handle 12 and withdrawn from the container. The swab or brush 11 is then applied to the surface to be lubricated. In this manner the amount of lubricant applied is directly controlled by the operator and the operation is carried out cleanly and easily.

The parallel walls S of the shell as well as the parallel portions of the walls 9 enter into a snug working it with the inner walls of the container and serve to effectually close the opening thereof. In this manner, the entrance of dust and other extraneous matter is prevented and evaporation of the lubricant is likewise prevented. The contracted open end 'of the shell 6 formed byl the tapering side walls 9 in addition to the functions hereinabove described, serves also to greatly facilitate the insertion of the shell in the container.

I claim A saw -oiler comprising a shell of rectanguiar cross section having a closed end and an open end, the walls of said shell adjacent said open end converging so as to contract said open end, a rectangular block of felt secured in said shellby frictional engagement with the inner walls thereof and by thea-ction of said contracted open end, said block having an integral swab extending 15 from said shell, a container adapted to house Said Shell and swab, said container having upper walls in snug working it with thev walls of said shell adjacent its outer closed end7 and having a chamber formed by the bottom 'Wall and lower side walls of Said container adapted to eect resaturation of said block.
