WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,-
Southampton Buildings, London. IMPROVEMENTS IN BRUSHES FOR CLEANING
THE INTERIOR OF TUBES AND THE LIKE," A. communication from abroad by Calvin
Burnham Rogers, of Saybrook, Connecticut, United States of America, Manu-
facturer.
This Invention relates to improvements in brushes designed to be used upon the
interior surface of articles of a tubular or similar configuration. It consists in the
application in alternate layers or tufts of a stiff and a soft material, the former to
scour and the latter to wipe the surface to be acted upon.
And it further consists
in providing in lieu of the single spiral groove. heretofore made use of for such
purposes two or more parallel spiral grooves in which the two kinds of material
are secured in any suitable manner.
The accompanying Drawing shows the construction of these brushes.
Figure 1 is a longitudinal section; and Figure 2 is a side view of one of the
said brushes.
Figure 3 is a longitudinal section of a brush of slightly modified construction.
Like letters indicate the said parts in all of these Figures.
A is the handle which is of any desired construction; it is provided at its upper
part with the two parallel spiral grooves B, C, in which are secured the aforesaid
stiff and soft materials, the stiff material D in one groove and the soft material E in
the other, the layers being continuous or in tufts, as preferred by the manufacturer.
The method of construction is the same as that of an ordinary brush, and the
materials to be employed do not differ from those used in other brushes. Thus,
bristles or any stiff material of a similar character may be used in one groove, and

the other groove.
Instead of the two parallel spiral grooves other means whereby the layers or
tufts of the different materials inade use of are placed alternately will effect the
chief object of this Invention. Nevertheless, I prefer that the two parallel spiral
grooves should be employed, as aforesaid, for this purpose.
It may be found desirable or expedient to use materials of different colors to
improve the appearance of the goods; this object is readily effected by selecting
colored yarns and other materials.
Having thus fully described the said Invention, as communicated to me by my
foreign correspondent, and the manner of performing the same, I wish it under-
stood that I claim, the improvements in brushes as above set forth and for the
purposes specified.
In witness whereof, I, the said William Robert Lake, have hereunto set my
hand and seal, this Nineteenth day of April, in the year of our Lord One
thousand eight hundred and seventy-six.
