PROVISIONAL SPECIFICATION.
Improvements in Tin Rollers for use in Spinning and like
Machinery.
We, EDMUND Tweedale, Samuel Tweedale and Joseph SMALLEY,
Machinists Castleton, near Manchester, do hereby declare the unturo of this
invention to be as follows:-
This invention relates to improvements in the construction of the cast iron
blocks or ends used in tin rollers & consists in arranging the boss so that the
appearance is improved, and truer running ensured when scrowed fast to the tin
roller shaft.
Hitherto this class of block has had the cap, or loose part, made the full longth
of the boss on the block itself, & in consequence the joint has shown on the
outside & has been liable to accumulate fluff & dirt.
The screws in the hoops that bind the blocks to the shaft have hitherto been so
arranged that the point has pressed on the fast part of the boss, thus tending to
distort or bulge it, and thereby impaired the true running of the block on the
shaft.
In carrying out our invention we shorten the loose part or cap so that it does not
shew on the outside and cast the part thus dispensed with (on loose part or cap) to
the block itself. This enables the block to be turned up true without showing the
joint.
The hoop for binding the block to the shaft is pinned or screwed loosely to fast
part of the block to keep it in position & the set screw for pressing the two parts
on tin rollor shaft is placed so as to press on the loose cap, thus avoiding any
tendency to cause the block to run untrue by distorting it through pressure of tho
set screw point.
Projections are cast on both the fast and on the looso parts of the blocks to keep
the hoop & loose part or cap in position.

COMPLETE SPECIFICATION.
Improvements in Tin Rollers for use in Spinning and like
Machinery.
We, EDMUND Tweedale, SamuEL TWEEDALE and JOSEPH SMalley,
Machinista, Castleton, near Manchester, 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 improvements in the construction of the cast iron blooks
or ends used in tin rollers, and consists in arranging the boss so that the appearance
is improved, and more even running ensured when sorewed fast to the tin roller
shaft.
In order that our invention may be fully and clearly understood we will make
reference to the accompanying sheet of drawings, and will first shew and describe
the present method of securing the cast iron blocks or ends to a tin roller shaft,

page_text: Fig. 1 represents a tin cylinder partly in section so as to shew the method of
fastening.
Hitherto the block A has had the cap or loose part B made full length of the
boss C including the part C¹ cast on the block, and in consequence a joint has
shewn on the outside which has been liable to catch and accumulate fluff and dirt.
An end view of the block is shown at Fig. 2, and Fig. 3 is an elevation of the
cap and Fig. 4 an end view of same. In applying this cap to the block, one end
has been inserted through the opening D and the hoop E has encompassed or
surrounded both the cap B and the boss C. The screw F passing through the
hoop E which binds the blocks to the shaft G, has hitherto been so employed that
the point of the said sorew pressed against the fast part of the lower boss C
thus tending to distort or bulge it and thereby provent the true running of the
block.
Our improved manner of fastening the block to the tin roller shaft is shewn
at Fig. 5 where A is the block with a full circular boss H on the face thereof
shewn in Fig. 6 and without any joint. In our caso the loose cap B is shortened
and it is not inserted through the opening D as in the old method, but is dropped
onto the boss C. The hoop E for binding the block to the shaft is pinned or
screwed loosely to the fast part of the block at I to keep it in position, and the
screw F for forcing the cap and boss C against the tin roller shaft G is used so as
to press onto the loose cap, which is in contra distinction to the present mothod,
thus avoiding any tendency to cause the block to run out of truth by distorting it
through pressure of the set screw point. Projections J are cast on both the fast
and on the loose parts of the blocks to keep the hoop E and loose part on cap B in
position.
By means of our invention the boss on the face of the block can be turned up
true, and as there is no joint accumulation of fluff and dirt which now. occurs cannot
take place.
Fig. 7 is an end view of Fig. 5.
Figs. 8 and 9 are details of the loose cap.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
Firstly. The construction of cast iron blocks or ends used in tin rollers having a
complete circular boss H, and the combination with the said blocks of a loose cap
applied in the manner shewn in Figs. 5 and 7.
Secondly. In securing cast iron blocks onto the shafts of tin rollers, we claim
