Complete Specification Left, 29th June, 1893-Accepted, 29th July, 1893
PROVISIONAL SPECIFICATION.
Improvements in the Method of Supporting Cylinders or Rollers of
Carding Engines and the like.
We, WILLIAM ACKROYD, Junior, of Spring Villas, Gomersal, and THOMAS
HENRY ACKROYD, of Oakroyd Hall Birkenshaw, both near Leeds, in the County
of York, Spinners and Manufacturers, and SAMUEL RAISTRICK of Top Mill Yard,
Birkenshaw aforesaid, Combing Overlooker, do hereby declare the nature of this
invention to be as follows;-
"
This invention relates to certain improvements in carding engines and the like,
and relates more particularly to the mounting of what are known as the "stripping
and "working" rollers by arranging the supports in such a manner that, should
any hard foreign matter enter the machine along with the fibre, the hard foreign
matter will be allowed to pass without danger of the brackets supporting the rollers
being snapped off and the liberated roller thrown on to the other rollers, thereby.
causing considerable damage to the card clothing.
We accomplish our object in the following manner. The bottom portion of the
bracket for supporting the roller is constructed somewhat as hitherto, but the cap
for holding the bearings supporting the roller shafts are provided with spiral
springs or the like, applied in such a manner that, should any foreign matter be
passing through the machine, on the same coming in contact with any of the
stripping or "working" rollers, the pressure of the spiral spring will be over-
come, and the bearings carrying the roller allowed to leave their ordinary working
position until such time as the obstruction has passed, when the said bearings will
be forced back to their normal position by the spiral springs.

COMPLETE SPECIFICATION.
Improvements in the Method of Supporting Cylinders or Rollers of
Carding Engines and the like.
We, WILLIAM ACKROYD Junior, of Spring Villas, Gomersal, and THOMAS
HENRY ACKROYD, of Oakroyd Hall, Birkenshaw, both near Leeds, in the County
of York, Spinners and Manufacturers, and SAMUEL RAISTRICK, of Top Mill Yard
Birkenshaw, aforesaid Combing Overlooker, 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 :-
"
This invention relates to certain improvements in carding engines and the like,
and relates more particularly to the mounting of what are known as the "stripping
and "working" rollers, by arranging the supporting journals in such a manner that,
should any thick substance enter the machine along with the fibre, the thick
substance will be allowed to pass forward without danger of breaking the supporting
brackets, straining the roller spindles or damaging the card clothing to any
great extent.
In describing our invention in detail, reference is made to the accompanying
drawings, in which
Fig. 1 represents an end view of a supporting bracket arranged according to this
invention.
Fig. 2 is another form of supporting bracket with the cap partly in section and
arranged according to this invention.

page_text: Figs. 3 and 4 are end views of the respective brackets each supporting the end
of a roller.
The bottom portion of the supporting bracket A. is constructed and secured
to the carding engine somewhat as hitherto and is supplied with a detachable cap B,
of novel construction held in the required position by set screw C.
The roller spindle D rests and rotates in the journal E, and above the said
spindle is a plate F secured to a spindle G, around which is placed a compressed
spiral spring H or an equivalent which will allow further compression should it be
required, such as for example, india rubber.
Each side of the carding engine is provided with a bracket A for supporting the
roller K, which is retained in the journals so long as nothing of a thick and hard
substance passes between the roller K and the one rotating in connection therewith ;
but should any thick substance come in contact with the said rollers, the strain put
upon the roller K will cause the spiral springs H. or other compressable substance
to yield and allow the same to pass thus obviating damage to the card clothing or
the straining of the roller spindles, as is the case when a thick substance passes
between rollers held in journals in the manner as hitherto.
In Figs. 2 and 4, the detachable cap B. is shown as applied to a journal
supporting spindle E of the ordinary construction, in which case the said spindle
passes through the bottom portion of the cap, held tight in the required position,
by the turning of spindle L, the roller spindle D being retained by a plate F,
spindle G and compressed spiral spring H or equivalent mounted in each B
cap
at the ends of the respective rollers and applied in the manner
described.
as before
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is :-
In a carding engine the arrangement and application of a detachable cap B,
plate F and spiral spring H or equivalent with a supporting bracket, journal E and
roller K substantially as and for the purpose as hereinbefore set forth.
