(Cl. 122-392) My invention has relation to improvements in boiler cleaners and is directed more particularly to the construction of the operating head where by the blower element is rotated; and it consists 5 in the novel features of construction more fully set forth in the speci?cation and pointed out in the claims. It is a matter of common knowledge among stationary engineers that when a boiler is ?red 10 for the purpose of raising steam, or when steam is admitted to the supply pipe of a boiler cleaner, expansion takes place, for which reason some ?exibility or play must be provided for between the boiler and supporting mechanism for the 15 boiler cleaner operating head. It is the object of the present invention to provide comparatively simple mechanism for sup porting the operating head of the boiler cleaner from the furnace wall wherein such freedom of 20 movement between the boiler wall and blower head is permitted to allow for the expansion men tioned without imposing strains upon the support ing mechanism. I accomplish this object by pro viding a single support on which the weight of 25 the operating head is carried and a suitable anchor device whereby the operating head is anchored to the boiler wall, by means of which support and anchor device the operating head is restrained only against downward movement and outward 30 movement away from the wall but being free to move upwardly and laterally within the compass necessary because of the expansion in operation. This object, as well as the manner of accomplish ing the same, will be better apparent from a de 35 tailed description of-the invention in connection with the accompanying drawing, in which: Figure 1 is a side elevation of the operating head of my improved boiler cleaner applied to a boiler shown in section, and parts of the head 40 being broken away; Fig. 2 is a vertical cross section taken on the line 2-2 of Fig. 1; Fig. 3 is a vertical longitudinal section taken on the line 3—3 of Fig. 2; and Fig. 4 is a cross-sectional de tail taken on the line ll—!i of Fig. 3. 45 Referring to the drawing, T represents the boiler tubes and W the boiler wall in which is provided an opening 0 through which the blower tube 1 passes. As is well known in the art, the blower tube I is supported by suitable hangers or 50 brackets 2 secured on the boiler tubes T. A Wall sleeve 3 is ?tted into the opening 0 and a plate 4 i's'secured by studs 5 at the corners of ?ange 6 extending around the outer end of the wall sleeve 3. The plate 4 has a bracket 7 extending up 55 wardly and a projection 8 extending downwardly from it and a stud 9 is screw-threaded into the upper end of bracket 1 for the purpose of anchor ing the operating head H to the plate 4. The operating head H is also supported against down ward vertical movement by the plate 4 through the 5 blower tube l by an adjustable supporting de vice comprising a supporting element I0 slidably mounted in oppositely disposed grooves II, II in the guide rails l2, l2. A threaded boss I 3 is formed adjacent to the lower edge of projection 8 10 of the plate 4 for receiving a stud I4 and the supporting element l 0 has a boss l5 formed on its lower edge which rests on said stud l4. The sup porting element I0 is thus adjustably supported by the stud M which may be secured in the cor- 15 rect position by means of a lock nut [6. The outer end of stud 9 is provided with threads t for receiving a nut i7, and over which is freely passed a thimble [8 having a ?ange [9 on its end adjacent to the nut ll (Figs. 1 and 3). Casing 20 C of the operating head H has mounted on it a supporting standard 20 in which the inner end of operating shaft 2| is mounted, and in which an eye bolt 22 is screw-threaded, said eye bolt pro jecting upwardly from the standard 20 and having an oval shaped eye 23 for receiving the stud 9 and thimble I8. The ?ange l9 of the thimble I8 is secured in the proper position on the stud 9 for cooperating with the ?anged nut 24 in holding the operating head horizontal. Figure 2 shows that the shape of the eye 23 is such to provide clear space entirely around the thimble I 8 so that a certain amount of movement of the operating head H is provided for due to the expansion of the boiler cleaner parts when the cleaner is in operation. The greater amount of movement due to expansion is in a vertical plane and the oval shaped eye 23 permits the head H to move up wardly and downwardly as required due to tem perature changes either in the boiler or the boiler cleaner. Since the blower tube l is not con?ned 25 80 35 40 but merely supported by the supporting element I0 it is tree to move upwardly away from said supporting element if conditions require such movement, and since it is supported on the 45 straight edge Ill’ of the element I!) it is also free to move laterally should the strains due to tem perature changes require lateral movement. The boiler cleaner is, of course, provided with a steam supply valve 25 disposed in the casing vC 50 and adapted to be opened and closed by a cam 26 freely rotatable on the shaft 2| adjacent to its outer end and manually operable, as is well known in the art. , A plate 2'! with a central opening 28 is posi- 55 2 2,017,846 tioned on the blower tube l in contact with the ?ange 6 of wall sleeve 3 against which the plate is held by ?at springs 29 to seal the opening through the wall sleeve against the in?ux of atmospheric air into the boiler furnace. Having described my invention, I claim: 1. In combination with a boiler, an anchor plate carried by the wall of the boiler, a boiler cleaner including a blower tube and an operat 10 ing head therefor operatively connected with said tube, vertically adjustable supporting means for said head and tube comprising a supporting element ?xed to the anchor plate beneath the blower tube and on which said blower tube rests, 15 and an anchor bolt projecting outwardly from the anchor plate and so connected to the head near the top thereof as to provide relative movement between the anchor bolt and head in all direc tions in a plane parallel to the boiler wall. 2. In combination with a boiler, an anchor plate carried by the wall of said boiler, a boiler cleaner including a blower tube and an operating head connected therewith, a pair of guide rails on said anchor plate, a supporting plate slidably mounted between said rails, means for adjusting said plate vertically and holding the same in ad 10 justed position, said blower tube resting on the upper edge of said plate, and an anchor bolt projecting outwardly from the anchor plate and loosely connected with the operating head. 15 LEO J.
