Improvements in the Construction of Sectional Blocks or Drums used
on Warping and Taping Machines.
ALFRED BARLOW, 119, Oxford Street, Oldham, Cotton Mill Manager, do hereby
declare the nature of this invention to be as follows:-
Sectional blocks or drums are usually made of wood. The edges become jagged in
use and cause broken threads.
I purpose making these drums either in part, or wholly of india rubber or any
other elastic composition.

Improvements in the Construction of Sectional Blocks or Drums used
on Warping and Taping Machines,
I, ALFRED BARLOW, of 119, Oxford Street, Oldham, in the County of Lancaster,
Mill Manager, 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 the construction of the sectional blocks or drums used
on warping or taping machines. Such sectional blocks or drums are usually made
of wood, and the edges thereof are liable to become splintered and jagged in use
and consequently to catch the threads which are thus liable to become broken.
The object of my invention is to remedy the defect and the manner in which the
same is to be performed or carried into practical effect will be readily understood
on reference to the annexed sheet of drawings and the following explanation thereof.
Fig. 1 is an elevation of an expanding drum or sectional block constructed
according to my invention.
Fig. 2 is a view showing the form (partly in sectional elevation) of the india
rubber cap fixed on the block.
Instead of making these drums of wood as hitherto practised I propose for the
purposes of my invention to make them either entirely of india rubber or other
suitable elastic material, or composition, or (preferably) partly of wood and partly
of such material or composition as shown on the annexed drawings.
The drum illustrated is composed principally of two pieces a and b made so as
to interlock in the usual way so as to be capable of expansion endwise, but instead
of making these pieces entirely of wood as heretofore I protect the outer edges or

page_text: ends thereof next to the steel discs c with caps d of india rubber or other suitable
elastic substance or composition, which not only protects the edges of the wood
and prevents it from becoming jagged or splintered, but also being elastic beds close
against the inner sides of the discs c and the ends of the block, so that there is no
crack or crevice between the same wherein the threads could become caught or
broken.
And for the same purpose so as to prevent the formation of a straight crack or
crevice between the inner edges of the caps d and the blocks a and b I make inden-
tations in the latter which I fill in with corresponding projections e on the elastic
caps d so that there is no straight crack or crevice across the points of junction
of the two into which the threads could become caught and thereby broken.
I would have it understood that although I have shown this method of applying
my invention to one particular form of sectional block or drum, for the sake of
illustration, I do not wish to confine myself to the exact details of construction
illustrated as the same may be considerably varied without departing from the
distinctive features of my invention.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is:-
-
The improvement in the construction of sectional blocks or drums used on warp-
ing or taping machines which consists of making them either in part, or wholly,
of india rubber or other suitable elastic material or composition substantially as,
and for the purposes, herein before specified.
Dated this oth day of January 1899.
