2 Claims.

This invention relates to a chimney borer and soot-churn nozzle. 1 An object of the invention is the construction of a simple and ei'licient device for use in extinguishing chimney fires.

Another object of the invention is the construction of a novel and efficient device, in which the rotary unit is entirely mounted upon a hub, which rotary unit and hub are provided with apertures or outlets of a specific construction, for

the purpose hereinafter set forth.

A still further object of the invention is the construction of a device ofthe class described, in which the parts are so assembled as to produce operate eiliciently over a long period of use.

With the foregoing and other objects in View, the invention comprises certain novel constructions, combinations, and arrangements of parts as will be hereinafter fully described, illustrated in the accompanying drawing, and more par-' ticularly pointed out in the appended claims.

In the drawing Figure l is a view in elevation of a device con- 2 structed in accordance with the present invention, while Figure 2 is a bottom plan view of same.

, Figure 3 is a horizontal sectional view taken on line 3-3, Figure l, and looking in the direction of the arrows.

Figure 4 is a vertical sectional View, taken on line 4-4, Figure 1, and looking in the direction of the arrows.

Figure 5 is an elevated view of the hub and a 35 portion of the handle.

Referring to the drawing, in which the preferred embodiment of this invention is disclosed, l designates a hollow handle, which is internally screw-threaded at the outer end as shown by dotted lines 2. The dotted lines 3 designate a suitliquefied chemicals, to the handle l; the means 3 being preferably threaded into the handle, by means of said screw-threads 2. This means 3 may be called the booster line, through which water may be passed from a tank (not shown), by employing a small pump mounted on a fire apparatus, etc.

On the outer end of handle I is formed an in- 0 tegral hollow hub 4. This hub 4 is provided with preferably four elongated outlets 5. her end of handle I and hub i there is an integral annular shoulder ii. The outer end 'i' of hub 4 is provided with a screw-threaded aper- 55 ture 8.

a device of durable structure, whereby it will able means for supplying liquid, such as water or On the in- A hollow ball a is entirely mounted on hub 4. This ball 9 is provided with an inner annular extension IQ, which extension bears against annular shoulder 6. The ball 9 is provided with an outer annular extension H. A fiat washer I2 is placed against end l and annular extension II with screw i 3 extending through said washer and threaded into said aperture 8, whereby the ball 9 is securely retained upon the hub, but is free to rotate, as desired. The ball 9 is provided prefer- 1o ably with three solid fins M, and extending through a portion ofthe ball 8 andeach fin I4 is an elongated aperture 55. These apertures l5 are formed or drilled at an angle to the nozzle.

It is to he noted that the fins M extend only 15 from the middle of the ball 9 outwardly to its outer end, at the annular extension H; upon referring to Figure 1, it will be noted that the outer endof each fin projects slightly beyond the outer face of annular extension H, thereby forming a 20 pocket or protecting'means for washer l2, inasmuch as said washer is substantially seated within portions of the fins, resulting'in no wear occurring upon the Washer, whereby the washer is not loosened or worn during the operation of the device.

It is to be understood that the rotatable ball 9 is actuated by reason of the apertures l5 being drilled at an angle so that the pressure from the chemical or water, passing through the booster line 3 will revolve the ball. The chemical or water is sprayed through the apertures l5 directly into the side of the chimney; these apertures [5 are small so as to use the leastamount of fluid. The apertures 15 are drilled at the base of the fins so that they will be protected when the nozzle strikes against theside of the chimney. As a result of placing the fins in spiral effect around the ball, anauger action will be obtained when boring through clogged soot in. the chimney. These fins will also churn up burning soot at base of a chimney.

By reason of the peculiar construction of the hub, and the peculiar placement of the ball thereon, a very strong and compact device is produced, which will have a long life, while at the same time will always produce efficient results.

While I have described the preferred embodiment of my invention and illustrated same in the accompanying drawing, certain changes oralterations may appear to one skilled in the art to which this invention relates during the extensive manufacture of same, and I, therefore, reserve the right to make such changes or alterations as shall fairly fall within the scope of the appended claims.

What I claim is:

1. In a device of the character described, a handle, a tubular hub at the front end of said handle formed with outlet openings in its sides, a spherical head rotatable on said hub, fins extending spirally about said head from the front end thereof and having their rear end portions extending parallel to the circumference of the head at approximately the middle of the head and terminating in end faces extending radially from the head, outlet ports being formed through the head at a tangent with their outer ends opening through the rear end faces of the ribs, and means carried by said hub at its front end for holding said head upon said hub in rotatable engagement therewith.

2. In a device of. the character described, a hollow handle provided with an integral hollow tubular hub at its front end formed with circumferentially spaced outlet openings, said hub and handle being provided at their meeting ends with an outstanding annular shoulder, a hollow spherical head rotatable about said hub, said head being provided at its rear end with an annular extension bearing against said shoulder and at its front end with an annular extension substantially flush with the front end of said hub, a washer bearing against the front end of said hub with its peripheral portion projecting radially therefrom for engagement by the front extension of the head to maintain the head upon the hub, a screw passing through said washer and engaged in a threaded socket formed in the front end of, said hub, and ribs extending spirally about said head from the front end thereof with their front ends projecting from the front extension of the head and across the peripheral edge face of said washer, said ribs having their rear portions extending parallel to the circumference of the head and terminating in end faces extending radially of the head, discharge ports being formed through the head and ribs at a tangent to the head with their outer ends opening through the rear end faces of the ribs.
