Maasai.
To all 'whomit may concern:
Beit known that I, JOSEPH A. CREPEAU, a subject of the King of Great Britain residing at Sorel, in the Province of Quebec and Dominion of Canada, have invented certain new and useful Improvements in Boiler-Tube Scrapers; 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'.
The'invention relates to improvements in boiler tube sera ers.
The object o the presentinvention is to improve the construction of boiler tube Scrapers and to provide a simple, practical and comparatively inexpensive device of this character designed to be operated by electric, steam or compressed air power and equipped with means for introducing jets of air into the boiler tube in rear of the tool to blow the dust away as soon as it is scraped from the tube. With these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the claim hereto appended, it being understood that various chan es in the form, proportion and minor detai s of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
In the drawing Figure 1 is a side elevation of a boiler tube scraper constructed in accordance with this invention, Fig. 2 is a central longitudinal sectional view of the same, Fig. 3 is a transverse sectional view on the line 3--3 of Fig. 2, Fig. 4 is a transverse sectional view on the line 4 4 of Fig. 2, Fig. 5 is an end elevation.
Like numerals of reference designate corresponding parts in the several figures of the accompanying drawing.
In the accompan ing drawing in which is re erred embodiment of the invention, the oiler tube scraper comprises in. its construction a tool 1, a holder 2, and y Specieationof Letters atent.
Application led'October 29, 1915. Serial No. 58,722.
forced outwardly by springs `9 mounted in recesses 10 in the inner edges of the bladesl and arranged within the said grooves 8. The blades which have beveled outer cutting edges 11 are provided with reduced terminal portions 12 extending beneath inner/and outer rings 13 secured on the cylindrical portion 7 in annular recesses 14 thereof by screws 15 which may be countersunk in the 'Patented anni, raie.
rings as shown in Fig. 5 or otherwise arranged.
The body of the tool is'provided at its intermediate portion 16 with an exterior annular groove 17 and a series of radially arranged jet apertures 18 communicating at their inner ends with the interior of the tubular portion 6 and adapted to discharge jets of air into the boiler tube operated on ata point in rear of the scraper blades to blow the dust from the boiler tube as soon as it is scraped off by the said blades 5.
The tubular stem or shank portion 6 of the body 4 of the tool screws into the outer end of the connecting pipe 3 and the inner or rear end of the connection pipe is threaded into a socket formed by a sleeve 19 which constitutes the front or outer portion of the holder 2. The holder is provided with a shank 20 having a head 21 circular in cross section and reduced at 22 and 23 to receive Aopening or bo're 28 of the handle 25 which is counterbored at the outer portion at 29 to receive a pipe or tube 30 ior connection with any suitable source of compressed air. rIhe shank 2O is designed to be mounted in a pneumatic drilling machine but it may be operated by any suitable power. The blades are rounded at their outer corners at the terminals of the cutting edges at 31 to enable the tool to be readily introduced into and removed from a boiler tube and it is adapted to be entirely passed through the same and operated in the ordinary manner,- the tool being rotatedl by the drilling machine or other power and the blades engaging the interior of the boiler tube are operated for scraping the dust and other accumulation l ters the tubular portion of therefrom. When the air is turned on at the ipe30 it passes through the hollow hand e or member 25 and enters-the recess 32 through the aperture 27, The-air then passes through the connecting pipe and ent e tool body 4 and is discharged at the exterior annular groove 17 through the jet apertures 18.
e What is claimed isz-- A boiler scraper including a tool comprisy ing a cylindrical body provided with 1ongitudinal grooves and having reduced portions at the ends of the grooves, blades operating in the grooves and .provided with spaced radially arranged. rectangular recesses at their-inner edges and having reduced terminal portions, spaced coiled by the terminal projecting portions of the blades to limit the outward movement thereof. 1' v In testimony whereof I aiix .my signature in presence of two witnesses. f
