SPECIFICATION forming part of Letters Patent No. 691,338, dateddanuary 14, 1902. Application filed July 20, 1901. Serial No. 69,094. (No model.)

T at whom it may concern:

Be it known that I,W1LLIAM GEORGE CLEM- ENTS, a citizen of the Dominion of Canada, residing at Vancouver, in the Province of 5 British Columbia, Canada, have invented a new and useful Saw-Oiler, of which the following is a specification.

My invention relates to improvements in that class of oiler designed for use with aband- 1O saw, and is intended to provide a continual lubrication of both surfaces of the blade while in use.

My aim has also been to makea device which is simple and elfective and which can be readily attached to existing saws.

Mysaw-oiler is fully illustrated in the accompanying drawings, in which- Figure 1 shows the position of the oiler on a handsaw. Fig. 2 is an enlarged side view;

Fig. 3, a cross-section on the line a a in Fig. 2, and Fig. 4 a detail of the gasketor joint ring.

In the views,S represents the saw-bladc,on each side of which I attach the cup-shaped members 2 and 3, which are connected and secured to the blade S by a screw 4, which passes through the center of 2,through an irregularly-shaped aperture 5 in the blade,and has its threaded end screwed into the center of 3,leather-washers6formingoil-tight joints between the edges of each piece 2 and 3 and their respective sides of the blade S, a small aperture 6 being left in each through which the oil may slowly feed onto each surface and 3; be carried down and distributed over them during use, the amount passing being regulated as desired by the tightness with which they are screwed together by 4. An oil-hole 3 is provided in one of these cup-shaped pieces, through which the chambers thus formed may be supplied, oil passing to the other side of the blade through the space between the screw 4 and the irregular outline of the aperture 5. This oil-hole is closable with the air-tight spring-controlled valve 7,

which is attached by the pin 8 on the member 8, which is hinged at 8 to the bottom of the cupped piece 3.

The hinge-piece 8 is of horseshoe form in outline to pass around the screw 4:, and the double ends 8 are folded over to receive the hingepin 9, which is secured to the cup-piece 3 by the projection 3", hammered on and folded over the pin 9.

A helical spring 10 surrounds the screw 4, and its smaller end bears against the horseshoe-shaped member 8 and its base against the blade.

.An important feature of my invention is the position of the oil-feeding aperture 6 in the gasket in relation to the direction of the motion of the saw, which position should be at the lowest part of the oiler when the saw is in use, and in the fact thatI provide every means of making the oiler air-tight elsewhere than at this feed aperture. If these points are observed the oil cannot flow out when not in use, because no air can enter to replace it; but the constant reciprocating movement when the saw is working allows the air to get in through the feed-apertures, and the oil consequentlyfiows out in just sufficient quantity to serve the requirements.

It is obvious that although I have described my device in its application to a handsaw it is equally applicable to the blades of a gangsaw or similar machine, though it may be necessary to use a cup member of oval or elliptical outline instead of circular, as drawn.

1 am aware that prior to my invention efforts have been made to attain the same result; but

\Vhat I claim as new, and desire to be protected in by Letters Patent of the United States, is

1. In an oiler of the class described, in combination with the blade of a handsaw having an irregularly-shaped aperture through the blade, adjacent to the handle; two cup-shaped members, the edges of which joint on the sawblade around the aperture, one on each side of the blade; the feed-aperture in each joint; the screw or bolt passing through the aperture and holding the cup members together and on the blade, and means whereby oil may be supplied to the chambers thus formed, substantially as described.

2. In an oiler as described, the combination of two cup-shaped members bolted together on each side of the blade of a saw, adjacent to the handle; the feed-aperture in the edge joint; the oil-hole in one of the members; and

the spring-controlled valve to close the oilhole, substantially as described.

In an oiler for lubricating a handsaw, the combination with the blade of the same having a hole through it adjacent to the handle, and the cup-shaped members bolted together with their edges surrounding the hole; the oil-hole in one of the cup-shaped pieces; the valve from the inside to close such; the

horseshoe-shaped piece to which the valve is attached by the pin entering the oil-hole; the hinge at the double end of the horseshoe shaped piece and the helical spring holding the valve closed until pressed open with the spout of the oil-can.

4:. In a handsaw-oiling device, the combination with the blade having an aperture 5 WILLIAM GEORGE CLEMENTS.
