JOHN A. HURLEY, OF ERIE, PENNSYLVANIA.

FLUE-CLEANER.

SPECIFICATION forming part of Letters Patent No.1329,045, dated October 27, 1885.

Application filed June 9, 1885. Serial No. 168,118. (No model.)

To all whom t may concern: Be it known that I, JOHN A. HURLEY, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented certain new and useful Improvements in Floc-Cleaners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to that class of steamboiler-line cleaners in which a jet of steam is used to blow the soot from the iiue; and it consists in improvements in the construction thereof, as will hereinafter be fully described, and pointed out in the claims.

My device is illustrated in the accompanye ing drawings, as follows:

Figure lis a side elevation of the device with its nozzle inserted in a boiler-flue, which is shown in vertical longitudinal section. Fig.

2 is a vertical longitudinal section of the nozzle, and shows the construction of the same and the valve contained therein. Fig. 3 is a iront elevation of the nozzle. Fig. 4 is'aside elevation of the device constructed so as to be applied to vertical iiues.

rIhe nozzle consists of a cylindrical shell, A, having atapered or conical face, a, and divided into two chambers, A4 and A5, by a partition, A2, in which is an opening closed by a valve, B. The mouth of the nozzle consists of an annular slit, a', arounda concave diaphragm, A', which is connected with the shell by bridges a2 or2 a2 a2. The back end of the shell is closed by a screw-plug, A3, through which is an opening for the valve-stem B', and is provided with a stuffing-box, B2. On the side of the shell is an opening into the chamber A4, into which a pipe, G, is screwed. This pipe connects with a iiexible hose, C', which connects with the steamsupply. At the outer end or" the pipe C there is a socket, D', into which a turned wooden handle, D, is inserted. On the handle D there is pivoted ahand grip-lever, E, which is connected by a rod, E', and proper couplings with the valve-stem B'. In the construction shown in Fig. 4 a bell-crank lever, El, and a second conn ectingrod,E3,` are employed to secure the proper connection. The valve B is kept upon its seat by aspring, S; but this is not essential, as the valve could be kept seated by the pressure of the steam.

The operation of the device is as follows: The operator makes the proper connection to a source of steam-supply with the hose O', and then inserts the nozzle, as shown in Figs. l and 4, into a iue and holds it in place firmly. He then presses down on the hand grip-lever E, and thus pulls open the valve B. This allows the steam to rush into the chamber A5 and out through the annular slit a' into the flue.

What I claim as new-is- 1. In a flue-cleaner, substantially as shown, the combination of a nozzle, a shut-off valve operating in said nozzle and having an outward-extending stem, a steam-supply pipe connecting with a flexible hose, a handle connected with said steam-pipe, and ahand griplever on said handle, which is operatively connected with said valve-stem, substantially as necting-rod E', connecting the said lever E with the valve-stem B'.

3. In a flue-cleaner, substantially as shown, the combination of a steam-nozzle, a shut-oft' valve within said nozzle, having a protruding Y stem, a handle connected with said nozzle, and

a hand grip-lever on said handle,which is operatively connected with said valve-stem.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN A. I-IURLEY. Witnesses:

JNO. K. HALLooK, BoB'r. H. PORTER.
