HANDLE ron saws 7 Application filed February 27, 1923. Serial No. 621,525.

It is the common Jractice b caroente'rs to carry a container having a small amount of oil and a swab for the purposes of oiling the saw and preventing the same from becoming rusty, or when they are working on timber having a large amount of resinous sap which has a tendencyto gum up the saw unless a small amount of oil is occasionally used. It is convenient, when working on roofs and elevated surfaces, to handle and carry an extra container with the oil. a

It is, therefore, the object of my invention to provide a saw handle having a container in which the oil may be carried with the saw, and to provide in the container, means of simple, durable and inexpensive construction for applying the oil to the saw. I

More specifically it is the object of my invention to provide asaw handle of metal having in its handle portion a hollow-compartment for receiving oil, the said compartment being providedwith a detachable swab designed to rest normally within the chamber and to be removed therefrom for the purpose of applying oil to the sunfaceof the saw. 1

A. further object is to provide insuch a device, improved means for' automatically closing the opening through which the swab is entered and removed, as the said swab is removed therefrom.-

7 These and other objects will be apparent to those skilled in the art. I V

My invention consists in the construc tion, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in 'm claims, and illustrated in the accom-- panying urawings, in which:

Figure 1 is a sectional side elevation of my improved handle.

1* igure 2 and Figure 3 is an enlarged, detail, elevation of the valve cage showing the manner in which the swab is mounted therein.

The numeral110 indicates a portion of the blade of a saw having a handle member 11 secured to the saw in the usual manner-by means of screws 12. The handle member 11 is provided with a hand engagingv handle 13, having a shape similar is a plan view of the same;

to the ordinary saw handles,the saw handle being made preferably of cast metal, such as aluminum with the handle member 13 cored out to form a compartment 1 1.

The upper end of the compartment 14 is provided with a screw threaded opening 15 which is designed toreceivea screw threaded lug '16, said lug having a smaller downwardly extending portion 17, and pro vided with a longitudinal opening 18. The said opening 18 is slightly wider at the top than at the bottom.

The bottom edge of the member 17 is provided with a beveled portion 19, which serves the purpose of a valve seat, as will hereinafter be made clear. The member 16 is provided with a hexagonal head 20 to provide means whereby the plug may be inserted in the opening 15 by means of a wrench or any other suitable tool. The upper end of the plugris provided with a smaller screw threaded portion 21 designed to receive a screw threaded cap 22.

washer 23 is provided on the under surface Secured to the outer face of the, member 7 I 17 I have provided a series of downwardly extending rods 27 so shaped as to form a cage to receive a ball valve 28. s

The lower end of the cage is provide with a coil spring 29 designed to engage the under surface of the ball 28. The cage 27 is designed to extend downwardly into the compartment 14% when the device is assembled, as clearly shown in Figure 1.

Assuming that the compartment 14: has been filled with oil through the opening 18, and that the cap 22 is in position, as shown in Figure l with the swab 25 within the cage 27, it will be seen that the concave plate 26 will force the ball downwardly against the action of the spring 29. If it is desired to oil the saw, the cap 22 is removed together with the swab 25 through the opening 18. As the swab 25 is moved outwardly, the spring 29 will cause the ball valve 28 to follow it andto finally engage the valve seat 19. The said valve provides a seal for the opening to prevent oil from running out while the swab is being used. After the desired amount of oil has been placed on the saw, the swab is again inserted through the large portion of the opening 18, then clownwardly until the plate 26 engages the ball valve 28, which is crowded downwardly to permitthe cap 22 to be screwed into position.

By thisarrangement it will be seen that I have provided a saw handle of simple, du-

rable and inexpensive construction, which may be applied to any of the saws in 00111- mercial use, and when applied, will provide means whereby the operator may easily and quickly apply a small amount of oil to the surface of the saw any time he wishes.

I claim as my invention:

A container having a screw threaded open ing, a hollow lug having its upper and lower ends externally screw threaded, a shoulder portion between the screw threaded portions, the lower end of said lug being provided with a pair of downwardly extending wire loops, one of which is arranged at right angles to the other to form a cage, an extensible coil spring on'the lower end of said loops, a ball on the upper end of said coil spring, a cap for the upper screw threaded portion of said lug, a pin extending downwardly from the central portion of said cap, a swab on the lower end of said pin designed to be drawn upwardly through the opening of said lug as the cap member is removed, the lower end of said lug being provided with a valve seat designed to be engaged by the said ball when the swab is removed. 7
