To c/,ZZ- whom it may concern/ Beit known that I, DAVID F. TBER, a citizen of the United States, residin inxthe city of New York, borough of Brook county of Kings, and State of New Yor have itivented certain new and useful44 -Improvements in Steam-Boiler-Tube Cleaners,
is a specification'.
My invention relates to what are known as blowers lfor injecting steam into .and through boilertubes for the purpose of dislodging and removing `soot and other solid products of combustion from said,tubes, and particularly to the class of such blowers dcsigned for use at the rear of return tubular boilers, the blowers in such cases being in# stalled in the rear wall of the combustionchamber. As heretofore constructed these blowers can only beapplied to the back walls ot' boilerfurnaces which are accessible from the rear and have to be operated manually.
My invention is desi ned td afford a comparatively simple an inexpensive blower which Vwill be automa-tic in action and which may be applied to the rear wall oany boilerfurnace, even though thereisf no available` 4space behind said rear wall, as. where the latter abuts against a wall, partition. er obstrucund. In the accompanying drawings, Figure 1 1s a vertical 4section of the rear portionA of are turn-tube boiler and furnace to which my blower is applied. Fig. 2 is a sectional elevav tion of the rearwall ofV the furnace, talrenupon the plane of line 2 2, Fig. 1. Fig. 3 isavertical longitudinal section or'y the casing. Fig. l is a side elevation of the rotatable nozzle. Fig. 5 is a vertical section upon plane of line .3 5, F ig. 7. Fig. 6 is an end elevation of the nozzle and'casing.` Figiflisfa section of the nozzle andcasing onplane of line] 7, Fig'. 6, the 'nozzle being in its no'rmaljorretracted position. Fig. -8 is afsirnilar View.

- A represents the rear end of ya returnflue boiler ofv any desired -typ'e orv construction,
and B' the rear wall of thefurnace inclosing the end of the boiler and the rear extension of the combustionechamber C. f
Embedded inthe wallB with its longitudil" nal axis preferably coincident or near] y coin# cident with the center of the area occupied by the tubes to be cleaned is the amm@ Specification of Letters Patent."
-d tothe'shell ward, as shown by way of` illustration in Fig.
D, consisting of a cylindrical shell having a port d at the rear, said port communicating .through a pipe or conduit d with a steam- `pressure pipe e,
m rovided with theV valve e. 1e pipe d su p ying steam through'theport i i3, is preferably inclined down- 2, and has interposed between it and the .steam-pressure pipe e a drip-chamber e, pro-- vided with .a petcock e, so' that when the valve e is closcdaftcr theblower has been. in use the drip or water of condensation may be drawn from both pi es.
The recess' b in t ewall B, in which the shell D is embedded, is preferably longer than the'shell .by approximately the extent or protrusion of the nozzle N,'so that thehead n of the nozzle'willbe 'su-bstantiallylush with the inner surface of the wall when thenozzle is in This is to protect the nozzle as far as possible from directconta'ct with the prod ucts of combustion in the chamber C.
- Thenozzle Nco'nsists of a hollow cylinder` `the mainportion of which is of less diameter than the internal diameter ofthe shell D, but which hasat or near its inner extremity an annular shoulder'v A'n' ol essentially .the same diameteras the interior o f the shell D, so as to fit snugly therein. f y
Formed integral with or rigidly secured to the shell D i's'an internal annular shoulder d2, between'which and-the annular shoulder n on the Anozzle'N is inter osed al coiled spring S,'whi ch'tends constant y to hold thenoz'zle N lretracted within the shell D. vThis retractilcmovement is limited by another annularsho'ulder 11,2. on the front end of the nozzle N, which rests normally against the inter- '.nal annular shoulder cl2 on the shell D.
f The'outer or face end of the nozzle is closed by @relatively-thick headfn., through which the' central one ofv which converge -inwardly toward the longitudinalaxis of the nozzle, so
to deflect the steam esca ing from the nozzle N over a relatively-wi e arca and inject the steam" into the'various tubes a of the boiler A, the said passages 4n n in the noz zle--head n being in sufficient number and arranged to meet the requirements of the class and size o?- boiler towhch the blower isto be applied.
(last or otherwise formed integral with. the
'nozzle'N .is a spiral Ablade (one or more) n,
incli ed with` relation to the longitudinal axis of the nozzle in. such manner that the llow of steam thro vhf-thelatter will' cause it to rof While I do notlirnit in self to any special method of construction, t e 'nozzle Nmay be cast in. one piece with the curved blade n* and head "n, thesteain-passages n n3 being cored in the latter. In such case the annular 'shoulders d and 11,2 are secured in position after the spring S` has' been applied peripherally to the nozzle N. In this connection it ma be noted that while the shoulders n, d2, auge are preferably of continuous annular form still this structure is not indispensable, since the main function of the sto s d2 and n is to act as bearings for the ends o -the 4spring S, while thatof the shoulder 11.2 is to act as a- 'stop or rest for the partsivlien their nor` ma positions at rest. In use when it is desired to blow out and clean the boiler-tubes al the valve in the supply-pie e is opened, thereby admitting steam un er pressure to the casing Dat the rear of the nozzle N. As a result the nozzle N -is forced forward against the resistance of the siirin S, and at the saine time the nozzle is rotated on its longitudinal axis by reason of thes pressure and ow' of the steam on andA over thespiral surface of the blade n4. By'
. this rotation of the' nozzle N the steam-passages in? n are made to inject the steam successively into all the boiler-tubes, and it will' benoted that this operation Will'be continuous and automatic as long as the steam-presi sure is i'naintained.` When the 4valve e is closed;the spring S returns .the nozzle N to its normal position out of contact with the roducts of combustion in the chamber C. hus installed in position` in the rear Wall ofthe 'furnace my' blovvcr requires no further attention, 'and there being no protrusion of the parts at the rear of the furnace-.Wall it can bG" applied'and used in situations Where 'access .cannot be had to the rear ofthe furnacefwall.
' Furthermore, the device is's'impl'e, cheap, andI durable in structure and notliable todeterio-f rate or get out oforder, as it isisolated and rotected and subject only to the wear invo ved in actual use, which is limited tothe automatic rotation of the nozzle.
