WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN ROLLS OR ROLLERS FOR
WRINGING AND OTHER MACHINES." A communication from abroad by George
Paysan Clark, of Windsor Locks, Hartford, Connecticut, United States of America.
The improved roller herein-after described is particularly intended for use in
large power driven machines used in bleacheries and dye works, but it is also
adapted for machines used for domestic purposes, as well as for various other
purposes for which squeezing rollers are used.
The said Invention is embodied in a structure, which consists of a series of rings
of india-rubber, or of compounds of india-rubber or of other suitable material,
arranged upon a central shaft with metallic vertebrae between such rings, and
articulated by means of them; the ends of the roll proper being also similarly
articulated with metallic flanges or discs connected with the roller shaft, and the
several sections coniposing the roll being compressed upon each other and clamped
by suitable devices between the end flanges.
In the accompanying Drawing,
Figure 1 is a perspective view of a roller constructed according to this Invention;
Figure 2 is a longitudinal section of the same.
Figures 3 and 4 show details of the said Invention.
A represents the metallic shaft of the said roll, which is furnished near one of the
end bearings with a solid permanent head or flange B. C, C, represent the rings of
india-rubber or other material. which compose the roll proper. Each of these
rings or sections is moulded or formed, as shewn in Figure 4, that is to say, its
opposite sides are made with a concave cavity a, in the bottom of which are radial
chambers b. The inner face of the flange B is similarly formed, and so also is the
[Price 4d.]

page_text: inner face of a metallic plate or washer D which is placed at the other end of the
roll and opposite to the fixed flange B, as shown in Figure 2. E, Figure 3, repre-
sents one of the metallic vetebrae which are articulated when placed on the shaft A
with the rings C, and those at the end of the roll with the flange head B and with
the washer D, as seen in section in Figure 2; these vertebrae have their opposite
faces convex or corresponding in form with the concave recesses in the rings C, and
in the head flange B and washer D. They have also on their faces raised ribs or
lugs c which fit into the radial channel b of such rings, flange, and washer
respectively.
Any desired number of rings C, formed as described, to make a roll of the length
required are placed, as shewn in Figure 2, upon the roller shaft, which is provided
with a permanent head or flange B, and the said rings are combined with the said
flange and with each other, as shown in the said Figure; the washer or circular
plate D is then placed over the end of the last ring composing the series, and
combined with the last vertebral piece in the series. The several rings are now to
be compressed forcibly against each other and clamped between the flange B and the
washer or plate D, this result is effected by the circular nut F which forms a
metallic head to the roll corresponding with the head B, and is fitted to turn upon
a screw thread & on the shaft A, so that any desired degree of pressure upon
sections composing the roll may be obtained. The nut after the compression is
effected may be held in place by means of screw bolts e, e, e, the ends of which
extend into and occupy corresponding holes in the washer D. The holes g and h
are simply for the insertion of levers to obtain the necessary purchase for screwing
up the nut F. By this construction heavy rolls for wringing, squeezing, or other
similar machines used to express liquid sfrom clothes and the like can be easily and
cheaply repaired when any one or more of the sections composing it become worn.
The several sections being articulated with each other and secured on the shaft,
as described, cannot turn upon the said shaft, and the capacity which exists for
compressing the several sections, and clamping them together, closes the joints
between the sections and renders the roll practically as impervious to water as if it
were made of continuous rubber without joints.
Having thus fully described the said Invention as communicated to me by my
foreign corrrespondent and the manner of performing the same, I wish it under-
stood that I claim,―
First. A roll or roller for wringing or other machines composed of sectional rings
articulated together and combined with the shaft, as above described.
Second. A roll or roller composed of elastic sectional rings articulated together
by means of intermediate inetallic vertebrae and mounted on a shaft provided with
end flanges for compressing the elastic rings, as above described.
In witness whereof, I, the said William Robert Lake, have hereunto set my
hand and seal, this Twenty-second day of July, in the year of our Lord
One thousand eight hundred and seventy-six.
