Letters Patent No. 92,752, dated J'uly 20, 1869.
IMPROVEMENT IN BOILER-FLUE SCRAPERS.
The Schedule referred to in these Letters Patent and making of the same.
To all whom it may concern.- l Beit known that I, MITCHELL A. SALoMoNs, of Boston, in the county of Suffolk, and State of Massachusetts, have invented an Improved Instrument for Cleaning the Flues of Steam-Boilers, of which the following isa full, clear, and exact description, reference being had tothe accompanying drawings, making part of this specification, in which- Figure l is a perspective view of my improved instrument forlcleaning the flues of steam-boilers.
Figure 2 is a longitudinal section through the centre of the same. Figure 3 is a transverse section on the line x a' of g. 2l v My invention has for its object to produce a strong, simple, and edicient tool for cleaning theiilnes of steamboilers; and
' It consists in a pair of spring-jaws, attached toa suitable handle7 each jaw being provided with a lip or flange, which bears against the interior of thejlue or tube, and serves to remove the scale and soot therefrom as the instrument is moved back and forth.
And, in combination with ythe above, my invention also consists in a circular plate, or washer, which closes the-opening at the'mouth of the spring-jaws, and collects the scale and soot, and aids in its removal.
And my invention furthermore consists in providing the spring-jaws with projecting arms or guidebars, which are' inclined toward each other, so that, when entered into they mouth of the line, they will force the'spring-jaws together, and thus facilitate the entrance ofthe instrument, the inner ends ot' the guide-bars being also -inclined toward each other, so that in withdrawing the instrument, after pushing it beyond the rear end of the iiue, the jaws willbe.
brought together, and the lips or tianges thereon prevented from being broken or injured by contact with the rear end of the flue.
To. enable others skilled in the art to understand and use my invention, I will proceed to describe the manner in which I have carried it out.
In the said drawingsf- A represents a strip of steel, bent around so as to form two jaws, a b, having curved enlargements 5 6 `at their outer ends, which are provided with lips or forthwith a. circular motion by means of the handle B, which is made of snfdcent length for the purpose. This handle is provided with a shoulder, d which abnts against the outside or bottom portion 7 of the jaws a b, the handle extending through this portion 7, and being held securely in place by a nut, c, turned over a screw-thread 8, beyond which a rod, f, formed in one and the same piece'with the handle, passes centrally and longitudinally between the open jaws a l), and has attached to its outer end, by a nut, h, or otherwise, a circular plate or washer, g, which closes the opening at the mouth of the jaws, and serves, as the instrument is moved back and forth, to collect and expel the deposit as it is removed by the lips or flanges c c.
. t i are arms or guide-bars, secured diametrically opposite each other to thetiaws a b, and inclined toward the axis of the instrument, so that when forced into the mouth of the flue, they will cause the spring-jaws to approach each other, thus facilitating the entrance of the flanges c c.
The inner ends of the guide-bars are also inclined from 9 to l0, where their outer surfaces are flush with the edges of the flanges c c, and thus, as the instru-` ment is withdrawn after pushing it entirely through and beyond the rear end of the flue, the jaws will be brought together, and the lips, or flanges c c, prevented from being b rokenr injured by contact with the rear end of the flue.
When the lips, or flanges c c, become worn away, from constant use, new ones may be 'formed by turning 'over the edges of the portions 5 6 of the jaws, a suficient amount of stock being left for this purpose.
If desired, a brush or a piece of cloth may be attached to the'rod f, between'the jaws, which will assist in cleaning the lues, andv freeing them from soot or dirt.
Claims.
What AI claim as my invention, and desire to secure by Letters Patent, is-
1. The construction of the jaws a b with their enlargement 5 6, and lips or anges c c, arranged substantially as described.
2. Also, the combination of the cirpular plate, or washer g, and rod f, with the jaws a l) and angcs c c, substantially as set forth.
Witnesses: M. A. SALOMONS.'
