BOlLER-TUBE CLEANER.

SPECIFICATION forming part of Letters Patent No. 359,383, dated March 15. 1887. Application filed December 16, 1886. Serial No. 221,724. (No model.)

To all wtfom, it may concern.-

Be it known that I, CHARLES FREDERICK POWER, ofPhiladelphia,in the county of Philascribed, and specifically pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a side view of Inyimproved form of boiler-tube cleaner. Fig. 2 is a central sectional view of the upper portion of the cleaner, the view being given upon an enlarged scale; and Fig. 3 is an end view of the nozzle as it appears when the deflector .is removed, the view being given` upon a still Ylarger scale.

Referring now to the general construction illustrated in the drawings, represents the nozzle of my improved form of boiler-tube cleaner. To the shank 11 Of this nozzle 10 there is attached a three-way coupling, 12, and to this coupling 12 there is connected a handle, 13, and a steam supply pipe, 14, said steam-supply pipe being provided with a valve or stop-cock, 15, and connected to a flexible tube or pipe, 16, upon the end of which there is secured a coupling, 17.

The nozzle 10 is made integral with a spider, 20, which spider is preferably made with three arms, as best shown in Figs. 2 and 3. At the point where the several arms of the spider meet there is formed-a threaded aperture, 21, that is arranged to be engaged by a threaded projection, 23, that is made integral with a circular deiiectingplate, 24, said deflectingplate being provided with a squared or irregular head, 25, which may be engaged by a wrench or key, so that the edges of the plate may be adjusted toward or from the ilaring edges 5 of the nozzle 10.

By securing the spider in the lowest and widest portion of the shell of the nozzle itl Offers but little Obstruction to the steam and affords a cheap, durable,and convenientlneans for securing the deflecting-plate.

In operation the coupling 17 is connected with the boileiat a point as near as possible to the top thereof, so as to insure the deliveryv of dry steam,the handle 13 is grasped with the left hand, and the steam-cock 15 is held by the right hand. The nozzle 10 is then inserted within the en d of the tube and forced inward, so that its inclined peripheral face 6 will bear hard againstthe end edges .of the bore of the tube, and steam is then admitted by turning the stop-cock or valve 15, which steam, passing into the nozzlelO, will be deflected by the plate 24, so that it will issue from the nozzle in a circular stream, striking against the entire inner face ofthe tube.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- A 1. In a boiler-tube cleaner, the combination of a nozzle-shell provided with a spider, 20, a defiecting-plate, 2i, secured to the said spider, and means for supplying steam to the nozzle, substantially as herein shown and described.

2. Ina boiler-tube cleaner, the combination, with a nozzle, of a spider made integral therewith, a deflecting-plate connected to thespider and provided with an external head, a coupling, 12, a steam-supply pipe connected to a flexible pipe that is provided with a coupling, a coupling connected to the end of the flexible pipe, and a handle connected to the coupling 12, substantiallyas described.
