PROVISIONAL SPECIFICATION.
Improvements in Lapping Apparatus for Clothing Carding
Machines.
1, SAMUEL EASTWOOD of 41 Durham Street Rochdale in the County of
Lancaster Card Nailer do hereby declare the nature of this invention to he as
follows
"
It is applicable to the lapping machines used for lapping metallic "card bands
upon the cylinders and "doffers" of carding machines, and has for its object the
facilitating and insuring of the correct lapping of the card bands upon the drum
into position for nailing or otherwise securing to the drum.
It consists of two drums or carriers of metal or other suitable material sliding
upon two parallel guides and connected rigidly together by metal plates through
which and between the two drums passes a long metal screw which takes in a thread
cut in the plates or attached to them.
The card bands are passed over and around the drums or carriers as many times
as necessary and are drawn over them by the rotation of the card drum it is
desired to cover. The friction over the large surfaces given by the carriei diums
gives great steadiness and insures the regular rolling of the card band upon the
card drums.
As the card band is drawn on the carriers it passes through a friction clutch
formed by a suitable weight attached to a suitable pivoted lever.
The long screw before mentioned is connected by suitable mechanism with the
card drum, so as to slowly draw the carrier drums across the face of the card drum
with a regular motion.

COMPLETE SPECIFICATION.
Improvements in Lapping Apparatus for Clothing Carding
Machines.
I, SAMUEL EASTWOOD, of 41 Durham Street, Rochdale, in the County of
Lancaster, Card Nailer 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 :--
It is applicable to the lapping machines used for lapping metallic "card" bands
upon the cylinders and "doffers" of carding machines, and has for its object the
facilitating and insuring of the correct lapping of the card bands upon the drum,
into position for nailing or otherwise securing to the drum.
It consists of two drums or carriers of metal or other suitable material sliding
upon two parallel guides or slides and connected together rigidly by metal plates
through which, and between the two drums, passes a long metal screw which takes
in a thread or its equivalent cut in the plates or attached to them.
The card bands are passed over and around the drums or carriers as many times
as necessary and are drawn over them by the rotation of the card drum it is
desired to cover.
The friction over the large surfaces given by the carrier drums
gives great steadiness and insures the regular rolling of the card band upon the
card drums.

page_text: As the card band is drawn on the carriers it passes through a friction clutch
formed by a suitable weight attached to a suitable pivoted lever.
The long screw beforementioned is connected by suitable mechanism with the
card drum, and slowly draws the carrier drums across the face of the card drum
with a regular motion.
In order that the foregoing may be better understood I send herewith a sheet of
drawings in which :-
Fig. 1 is a side elevation, Fig. 2 a plan, and Figs. 3 and 4 two end elevations of
my apparatus.
In
In all the figs. a indicates the carriers or drums (which may be circular as shown,
or semicircular) these are connected together rigidly by the plates a 1 and a 2.
one of these plates (a 2) is fitted a pinion wheel d with suitable teeth for taking in
the thread of the long screw c, so that when fixed by the set screw g it forms a
thread by means of which the long screw c slides the carriers a along the
rods or guides b, the screw c receiving its motion by means of the pinion / at
its end.
The card band is passed through the friction clutch e consisting of the
presser k which is weighted by the weight f, and thence round the drums or
carriers a as many times as necessary, projections a 4 keeping it in its proper
position.
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 :-
1st. The combined apparatus, substantially as described and shown hereinbefore,
and in the accompanying drawing, for the purpose set forth.
2nd. The combination of two drums or carriers rigidly connected and sliding
upon two parallel guides, with a long screw for sliding the same, substantially as
described and shown hereinbefore and in the accompanying drawing, for the
purpose set forth.
