PROVISIONAL SPECIFICATION.
Improvements in Means for Supporting Rollers in Rolling Mills and
in Wringing and other Machines.
THOMAS WILLIAMS 13 Hutchinson Street Stockton-on-Tees County of
Durham, Blacksmith, do hereby declare the nature of this invention to be as.
follows:-
My invention has for its object the prevention of the sudden closing of all
descriptions of rolls or rollers, after any substance or material has lifted the top
roll or roller when passing between them, and so preventing damage to rolls
or rollers, also to all machinery connected therewith, such as spindles, shafts, boxes,
spur-gear, or any other appliances. For the purpose of my invention I have spiral
springs of sufficient strength, one or more fitted at each end of the rolls or rollers.
Into the inside of each of these springs are inserted two short bolts or rods, one at
the top, and one at the bottom, each having a square or oblong head bearing on the
end of the spiral spring, and hollowed out for bearing on each spindle or neck of the
rolls or rollers.
The bolts or rods under the springs are of requisite length to allow the springs to
bear the weight of the top roll or roller, and the pressure usually applied thereto
when in use.
My invention can be readily applied to all rolls or rollers in use for the manu-
facture of plates composed of any metal, as well as for wringing machines for
clothes.

COMPLETE SPECIFICATION.
Improvements in Means for Supporting Rolls in Rolling Mills and
in Wringing and other Machines.
THOMAS WILLIAMS 13, Hutchinson Street Stockton-on-Tees, County of
Durham Blacksmith, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
My invention has for its object the prevention of the sudden closing of all
descriptions of rolls or rollers, after any substance or material has lifted the top roll
or roller or lowered the bottom roll or roller, when passing between them; and
preventing damage to the rolls or rollers or to any parts of the machine or machinery
connected therewith.
For the purpose of my invention I have spiral springs sufficient in strength and
in number, of any shaped section fitted between the upper and lower rolls or rollers
at both ends of the same.
In wringing machines or other machines of light construction these springs are
placed directly under or over bearer or bearing to be described hereafter.
To keep the springs in required position a short pin or bolt is inserted inside the
spring, both at the top and the bottom thereof, and either cast or welded on, or
fastened by any suitable means to the bearer or bearings; or each end of the spring
may be inserted in a hole in each bearer or bearing.
Each bearer or bearing is hollowed out on the topside or underside to suit the
spindles of the machine, and the sides are shaped to suit the standards or frames of
each machine; so that the bearer or bearing can slide easily up or down as
required.

page_text: For rollers in rolling machines or for machines of heavy construction the springs
rest on the bottom of the standard or frame of the machine, and are kept in their
true position by a pin inserted inside the spring at the bottom thereof, or by the end
of the spring being inserted in a hole in the standard.
The springs are kept in their true position at the top by a pin cast on or inserted
into the movable bearer or chock, which supports the brasses or journals of the top
movable roll or roller.
The accompanying drawings illustrate my invention.
Fig. 1 is an end view of parts of a wringing machine or machine of light
construction.
Fig. 2 is an end view of parts of rollers or rolling mills or machines of heavy
construction.
The same letters refer to similar parts in each figure.
The spiral spring or springs A, A are kept in position by the pins B, B, or can be
inserted in holes in bearers C, C, in Fig. 1, or into lower part of standard K, K,
and into movable bearer H, H, in Fig. 2. The bearers C, C, are hollowed out to
suit spindles or necks D, D, in Fig. 1.
The standards or frames G G. of each machine are shown in Figs. 1 and 2.
When the material has passed between the rolls or rollers, and the rollers fall
either by their own weight or accelerated by the pressure which is usually applied
by a screw, weight, or spring; the spiral spring will effectually support the rollers
and so prevent the sudden closing of the same."
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed;-I declare that what I
claim is,―
A simple method for supporting rollers in rolling mille or in wringing and other
machines, and preventing the sudden closing of the same, by the use of spiral
springs; and means for keeping the same in proper position, and acting on the
spindles or necks of the rolls or rollers.
Dated this 31st day of July 1893.
