LUBRICATOR FOR SAW-BLADES.-

Specification of Letters Patent.

Patented Aug. 10, 1909.

Application file'd January 5, 1909. Serial No. 470,789.

ily Operated when required, whereby lubricant may be discharged at will upon the saw blade so that it'is enabled to make. a narrower and smoother kerf with less friction. A saw blade thus lubricated, re uires less set or spread of the teeth, and wil do closer smoother work with the application of less force.

Thedetails of construction, arrangement,

scribed and illustratedin the accompanying drawing in which-- Figure 1 is a side viewpart being broken away-of the handle and a portion of the blade of ahand-saw with our improved lubricating attachment applied thereto. Fig. 2 is a section on the line 22 of Fig. 1. Fig. 3 is a view illustrating the operation of our lubricating attachment.

.The hand-saw blade 1 is provided with a handle 2 which may be of the usual construction. Our lubricating attachment is composed of a drum-like lubricant-holder 3 having a filling-tube 4, and discharge-tubes 5 provided with stoppers 6. The holder 3 extends throughthe handle 2 transversely, and is provided with slightly convex ends3 which are elastic to the degree required'to enable them to be compressed, or pressed inward, as shown in Fi 3. The dischargetubes 5 extend from t e holder-3 forward, and are arranged on 0 blade 1. The nozzles o e'same are turned inward toward the blade, and provided with conical stoppers 6, which are attached to wires 7 that are in'turn connected with the respec-- It will beseen tive heads 3 of the holder. in Fig. 2, that the wires 7 cross each other within the holder and are formed at that 7 point with lateral bends or kinks, which provide sufiicient elasticity to enable the wires to hold' the. stoppers retracted within the plosite. sides of the 13 shown in Fig. 2. The filling-tube 4 is made of a considerable diameter so that it serves practically as an enlargement of the holder 3, or in other words enables a larger quantity of lubricant to be stored for use than would be practicable if the tube were sim 1y large enough to serve as afilling duct. ts

' outer end is provided 'with a screw cap 4,

which is enlarged and hollow and thus'serves as an enlargement or extension of the fillingtube 4.

The practical o' eration of our lubricant attachment is as ollows: It being assumed that the holder 3, together with its fillin tube and the dischargetubes 5, is filled wit oil, when it is desired to lubricate the saw,

pressure is applied laterally on the heads 3 of the holder, whereby they are pressed inward as shown in Fig. 3, by which movement the stoppers 6 are rejected slightly from the nozzles of the disc arge-tubes and lubricant caused, or allowed, to flow from the tubes upon the saw blade. Immediately u on the release of pressure on the heads of the older, they resume the normal position shown in Fig. 2, by reason of their own resiliency, and

the elasticity of the wires 7, aids indrawing the stoppers 6 firmly into the nozzles, or months, of the discharge-tubes 5 so that they are tightly closed against the escape of lubricant.

It will be seen that our improved attach ment provides a convenient means for lubricating a saw blade whereby'it'is ada' ted to be used with less friction, and to ma e a narrower and smoother kerf, thus saving'an a preciable amount of lumber in working up tli e same, and-considerably lessening the labor of the operator.

It is obvious that the location or osition of the holder 3 may be changed wit out seriously affecting the operation of the attach-' ment as a whole. .For example, the holder might be located at 8, as shown by dotted device is located as shown in Fig. 2, the handle is preferably rovided with a gullet of- 1.
