SAW-OILING DEVICE.

Specification of Letters Patent.

Patented June 11, 1907.

Application filed April 9, 1907. Serial No. 367,294.

To all whom it 'nmy concern:

Be it known that I, HARM SCHURING, a citizen of the United States, residing at WVashington, District of Columbia, have invented certain new and useful Improvements in Saw Oiling Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to oilers or oil cups for hand saws. I

It has for its object to provide an oil cup of simple construction which may be easily and quickly fastened at any point on the saw blade where it is desirable to have the oil fed.

The invention consists in the features of construction and combinations of parts here inafter described and specified in the claims.

In the accompanying drawings, illustrating the preferred embodiment of my invention: Figure 1 shows a part of an ordinary handsaw with my oiler attached to the blade in proper position when the saw is to be used in a vertical or oblique line, the position of said oiler when the saw is to be used in a horizontal line being shown in dotted lines. Fig. 2 is an enlarged central longitudinal sectional view of the oiler.

Referring more particularly to the drawings, 1 designates the saw blade and 2 the handle. The oiler or oil cup 3 comprises an integral bifurcated portion or nozzle 4 and a can or receptacle 5 for the oil. The slot 6 in the nozzle is wide enough to receive the blade of the ordinary saw. The nozzle ta pers toward its outer end and is adapted to be clamped upon the saw blade by a nut 7 having its interior threaded portion beveled and engaging a beveled threaded portion 8 on the nozzle. The slot 6 extends up past the nut to give a certain degree of flexibility and resiliency to the bifurcations.

The can or receptacle 5 is screwed upon the upper end of the nozzle and all leakage is prevented by the end of the thread portion or neck of said can contacting with a flexible washer 9 seated upon a shoulder 10 formed on the nozzle. From the upper or inner end of said nozzle a passage 1.1 extends through each bifurcation. These passages are tapered and larger at their upper ends in which are inserted the arms of a bent spring wire flow regulator 12. It will be understood that by inserting the arms of said bent wire device farther into the tapered passages 11, the flow of the oil will be lessened while,

V by withdrawing said arm more or less, the

flow will be increased. In use the arms may be adjusted at the desired point before the nozzle is screwed into the can and the flow of oil will be regulated accordingly. It will be noted that the resiliency of the arms hold them in position by contact with the walls of the passages 11 at whatever points they are placed. A forced flow may be obtained by pressing the flexible sides of the can in same manner as the bottom of an ordinary machine oil can.

As shown in solid lines in Fig. 1, the oiler may be placed on the end of the blade of the saw just above the teeth, whereby the oil is fed to said. teeth where it is required. \Vhen an oiler is arranged in the handle or on the rear edge of the blade, a large part of the oil soaks into the wood being sawed and never reaches the teeth. If the saw is to be operated in a. horizontal line so that the oiler if placed on the end of the blade would be in the way, said oiler may be placed on the rear edge of said blade as shown in dotted lines in Fig. 1. Probably the most important advantage of my oiler over those previously invented and used is that it may be secured to the saw blade at any point desired. It can also be readily attached to any saw which is not the case when the oiler is made in the handle as is generally done.

My device is very simple in construction and requires no skill to operate it.

I claim:

1. An oil cup provided with a bifurcated discharge nozzle, means to clamp said bifur cations upon the blade of a saw, and means to feed oil through said bifurcations.

An oil cup provided with a bifurcated discharge nozzle having a beveled screw threaded portion, an intcriorly beveled nut engaging said beveled portion of said nozzle whereby the bifurcations may be clamped upon the blade of a saw, and means to feed Oll through said bifurcations.

An oil cup provided with a bifurcated discharge nozzle having a beveled screw threaded portion, and an interiorly beveled nut engaging said beveled portion of said nozzle whereby the bifurcations may be clamped upon the blade of a saw, each bifur cation containing an oil passage for the purpose specified.

4. An oil cup provided with a bifurcated 6. An 'oil cup provided with a bifurcated discharge nozzle, means to clamp said bifurcations uponthe blade of a saw, an oil re- 15 l ceptacle having flexible sides, and means to feed oil through said bifurcations.
