Machinist trading under the style of George Newsome of Rochdale aforesaid
Maker of Card grinding appliances, emery rollers and the like for an
Invention of IMPROVEMENTS IN' CARD GRINDING MACHINES AND EMERY
PROVISIONAL SPECIFICATION left by the said George Hoyle at the Office
of the Commissioners of Patents on the 20th December 1883.
GEORGE HOYLE of Rochdale in the County of Lancaster, Machinist, trading
under the style of George Newsome, of Rochdale, aforesaid, Maker of Card
grinding appliances, emery rollers and the like. "IMPROVEMENTS IN CARD
GRINDING MACHINES, [AND] EMERY ROLLERS FOR THE SAME, AND FOR OTHER
PURPOSES."
My invention relates to the frames of card grinding machines and to the emery
rollers employed in the same and the objects of my Invention are first to improve
the frame so that it will hold the card roller firmly and steadily and enable me
readily to move the card roller to and from the emery roller and at the same time
keep the two rollers exactly parallel to one another and also to set the frame when
the parts are properly adjusted for working, in such manner that all back-lash is
avoided and secondly, to improve the construction of emery rollers so as to render
them light and strong and more durable than those of the ordinary construction.
In performing the first part of my Invention I fit on the frame of the card
grinding machine another frame or table which bears on the machine frame and
may be moved backward and forward in and be guided by, slides, antifriction
pulleys or in other convenient manner: to this table are secured brackets, with
suitable bearings for holding the card roller, one of these bearings being adjustable:
The table with the card roller may be traversed backward and forward on the
machine frame to or from the emery roller by means of levers or cranks, keyed or
secured to a rocking shaft, parallel with the card roller, and actuated by a worm

page_text: wheel and worm or in other convenient manner; or the cranks may be dispensed
with and other mechanical equivalents employed to traverse the table.
For a double machine for grinding two card rollers simultaneously a second table
and duplicate mechanism for operating the same would be required, and the tables
may be coupled by a slide or otherwise.
To set the table when the parts are properly adjusted for working I fix a stud
with a screw thread to the machine frame; this stud passes through a slot
preferably near the centre of the table; a small hand pulley or thumb screw may
be screwed on to this stud, which holds the table fast, and thus prevents vibration:
the slot may be formed in the frame, and the stud fixed to the table, and spiral
or other springs may be fastened to the table to give it additional steadiness if
required.
In performing the second part of my invention I employ, by preference, a brazed
metal tube, but any other suitable metal tube may be used to each end of this
metal tube I attach a metal end or block, fitted so that the tube cannot turn round
the block; a rod, square throughout the whole or part of its length, passes through
the metal tube and ends, and a short shaft is screwed on or otherwise secured to
each end of this rod these short shafts form the axis upon which the roller
revolves, and are formed with shoulders which fit into corresponding recesses in the
metal ends; a small screw or peg may be fitted into the shoulder of each shaft and
metal end or block, so as to prevent the shafts from working loose.
If necessary the metal tube or roller may be balanced by means of a weight
secured to the rod passing through it, or to the inside of the tube or metal ends.
The roller is then coated with cement, and emery, and finished in the usual
manner, and may be applied to any purpose, where such emery rollers are required

by the said George Hoyle in the Patent Office on the 17th June 1884.
GEORGE HOYLE, of Rochdale in the County of Lancaster, Machinist trading
under the style of George Newsome, of Rochdale aforesaid, Maker of Card-
grinding Appliances, Emery Rollers and the like. " IMPROVEMENTS IN CARD
GRINDING MACHINES AND EMERY ROLLERS FOR THE SAME AND FOR OTHER
PURPOSES
"
My invention relates to card grinding machines and to the emery rollers
employed in the same and the objects of my Invention are first, to improve
the frame so that it will hold the card roller firmly and steadily and enable ine
readily to move the card roller to and from the emery roller and at the same time
keep the two rollers exactly parallel to one another and also to lock the frame when
the parts are properly adjusted for working, in such manner that all back-lash or
shaking is avoided and secondly, to improve the construction of emery rollers so
as to render them light and strong and more durable than those of the ordinary
construction.
And in order that my Invention may be fully understood and readily carried
into effect I will proceed to describe the accompanying two Sheets of Drawings,
reference being had to the figures and letters marked thereon.
Fig. 1 is a front elevation. Fig. 2 is a plan and Fig. 3 is an end view of my
improved card grinding machine and Fig. 4 shows a section of my improved emery
roller.
In performing the first part of my Invention illustrated by Figs. 1, 2 and 3 I fit
on the frame a of the card grinding machine another frame or table b which bears
on the machine frame and may be moved backward and forward in and be guided
by slides a¹ or in other convenient manner: to this table b are secured brackets c c¹
with suitable bearings for holding the card roller, one of these bearings c¹ being
adjustable: the table b with the card roller c² see Fig. 3 is traversed backward and
forward on the machine frame a to or from the emery roller d by means of a screw g
or other mechanical equivalent and I employ levers or cranks e keyed or secured to
a rocking shaft parallel with the card roller to steady the table b. The ends of
the cranks e move in slots formed in projecting parts b¹ of the table b. I connect
a spring to the crank or crank shaft to give additional steadiness if desirable. The
machine shown is a double machine for grinding two card rollers simultaneously
with two tables and duplicate mechanism for operating the same: the tables may
be coupled by a slide or otherwise.
To lock the table b when the parts are properly adjusted for working I fix a
stud h with a screw thread to the machine frame: this stud passes through a slot
preferably near the centre of the table: a small hand pulley or thumb screw may
be screwed on to this stud which when tightened locks the table fast while the
roller is being ground and thus prevents vibration: the slot may be formed in the
frame and the stud fixed to the table. Longitudinal slots are formed in the table a
for adjusting the brackets b b so that they may hold any length of roller to be
ground. The brackets b b¹ can be used (when the top part has been removed) for
carrying a turning up rest, so that the wood rollers (wood workers and clearers)
used in woollen mills may be placed in the bearings of the emery roller to be
"turned up."
In performing the second part of my Invention illustrated by Fig. 4. I employ a
brazed metal tubes with balance weight a¹ but any other suitable metal tube may
be used to each end of this metal tube s I attach a metal end or block t on one of

page_text: which is a projection t¹ that passes through a slot in the tube 8 so that it cannot
turn round the block: the rod u square at u¹ passes through the metal tube and
ends and a short shaft vis screwed on (or may be otherwise secured) to each end
of this rod these short shafts v form the axis upon which the roller revolves and
are formed with shoulders which fit into corresponding recesses in the metal ends t:
a small screw or peg may be fitted into the shoulder of each shaft and metal end or
block so as to prevent the shafts from working loose.
If necessary the metal tube or roller may be balanced by means of a weight 8¹
on the tube or secured to the rod passing through it or to the metal ends. The
roller is then coated with cement and emery and finished in the usual manner and
may be applied to any purpose where such emery rollers are required. In place of
the rod a pipe may be used and the shafts v may have screwed ends by which
they are secured to the pipe.
Having stated the nature of my Invention and described the manner of
performing the same.
I declare that I claim
1. The improved machine for grinding card rollers, substantially as herein
described and as shown.
2. The sliding frame or table b as and for the purpose herein shown and
described.
3. The combination of the sliding table b and the cranks e as and for the
purposes herein set forth.
4. The improved emery roller herein described and shown on Fig. 4.
In witness whereof I the said George Hoyle have hereunto set my hand and
seal this thirtieth day of May One thousand eight hundred and eighty four
