I ALFRED GEORGE BROOKES of the firm of Wm. Brookes & Son of 55 &
56 Chancery Lane in the County of. Middlesex, Fellow of the Institute of Patent
Agents do hereby declare the nature of this invention (a communication from
abroad by Elihu Purinton Collins and Joshua Robinson both of Lawrence County
of Essex in the State of Massachusetts one of the United States of America,
Gentlemen) and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
This invention has for its object to simplify and cheapen the construction of
warp beams used in looms and other machinery wherein warp is handled upon
beams.
Ordinarily the heads of such beams, provided at their centres with annular
flanges to form hubs to embrace the beam, are attached thereto by screws and
wedges, the screws passing through holes in the hubs, the wedges being driven into
the space between the hubs and beam.
In accordance with this invention the head instead of having an open annular
hub, has a divided or separable segmental hub, in order that one part of the hub,
preferably substantially one-half of it, may be moved away from the other half, the
said movement being preferably accomplished by means of a screw or equivalent
adjusting device.
In accordance with this invention the two segmental parts of the hub may be
simultaneously clamped upon the beam in any desired position, or may be separated
when it is desired to adjust the head on the beam.
Preferably one or both the segmental sections constituting the hub will have one
or more points or projections to enter the beam and thereby prevent longitudinal
movement of the head upon or with relation to the beam, but it will be understood
that these points may be omitted,

page_text: The divided hub is shown as provided with short concaved bearings to aid in the
adjustment of the head to unequalities of surface of the beam, and so also the head
is shown as provided with an elongated opening, the end of the said opening
opposite the rigid segmental hub constituting a fixed part of the head, being of a
different are than the said fixed part of the hub, or of the movable part of the hub
attached to the radially movable plate, to be described, such enlarged or elongated
opening when the segmental hubs are separated affording space for the movement
of the heads on the beam.
To keep the warp threads from entering this space, each radially movable plate
has been provided with a projection to span or bridge the said space when the head
is clamped to the beam.
This invention consists in a warp-beam head composed of a disc having an
attached segmental hub, and of a separate movable plate having a segmental hub
integral therewith, the said plate being arranged to slide radially in the said disc,
substantially as will be described.
Figure 1 in elevation shows one end of a warp-beam with this invention applied
thereto, the friction ring being broken out to show the hub beyond it.
Figure 2 is a side elevation of part of the beam head, slide-plate, and friction
ring, the head being partially broken out.
Figure 3 a section of Figure 2 in the dotted line a looking to the left.
Figure 4 is a section of Figure 1 in the dotted line x chiefly to show the means
for preventing the movement of the outer end of the sliding plate laterally from
between the ribs between which it slides.
Figure 5 is a side elevation of the sliding plate and its attached segmental hub
received from the head, and
Figure 6 is a section of Figure 1 in the line x³.
The beam A, upon which will be wound the yarn or thread, may be of any
usual size, length and material, it being provided with journals B¹, driven therein,
the said journals being either short rods, as shown in Figure 4, or of other usual
construction.
The improved warp beam head is composed of a disc a provided at its centre with
an elongated or somewhat oval opening, as 20.
The disc has an attached segmental or semi cylindrical hub a¹, the hub being
strengthened preferably by a rib a' extended from it outwardly to the periphery
of the disc a, which latter, at its periphery, and to secure greatest strength for the
disc with the least weight of material is also provided with a rib or lip a³, the said
lips a and a being preferably continuous and formed by casting.
The slide 6 having the segmental or semi cylindrical hub b¹ to cooperate with the
hub or part a¹ and constitute a two-part hub to firmly embrace the beam A, is
adapted to slide in the space between the ribs a³, a², the disc a being cut away at
10 and 12, see Figures 3 and 4, to receive projections 13 and 14 extended from the
rear side of the plate b to be described, the projection 14 constituting a bridging
projection having, as herein shown, a point 3.
The upper part, see Figure 3, of the central hole 20 in the disc a, is made of a
greater circle than the lower part having the point 2, or the said hole 20 is elongated
or is not truly circular, such construction enabling the head to be readily moved or
adjusted on the beam when the plate b is loosened, as will be described.
When the head has been moved into proper position, the segmental hub 6¹ will
be forced inwardly by the adjusting device or screw d, until the said segmental
hub b and the segmental hub a¹ grasp closely between them the circular periphery
of the said beam, the bridging projection 14 at such time resting with its lower edge
below the edge of the hole or opening 20 in the disc a, and against the beam A,
thus preventing the warp threads from entering the space, see Figure 3, which is
left between the inner edge of the hole 20 in the disc a and the concaved lower end
of the plate b at its junction with the flange b¹.
The flange at of the disc a is shown as provided at its interior with a prong 2 to
enter the beam,

page_text: Both hub parts a¹, 61, are provided with short concaved bearings 16 to act
against the periphery of the beam and afford rigid seats for the head, notwith-
standing irregularities at the periphery of the beam.
The outer end of the radially movable plate b is acted upon by an adjusting
device d, shown as a screw extended through an ear d¹ and acting upon the end of
the plate b, rotation of the adjusting device in one direction causing the plate b to
be forced toward the axis of the beam A, such movement of the plate causing the
segmental or separable parts a¹, b', of the hub to be forced snugly against and to
embrace closely the said beam, the points or projections 2, 3, see Figures 1 and 2,
at such time entering the beam.
When the screw is moved in the opposite direction, the two-part hub may be
separated in order that the beam head may be removed from the beam or be
adjusted to a different position.
To enable the adjusting device d to be rapidly turned, its head has been made
square to receive a handle or crank e, shown by dotted lines.
To prevent the lateral movement of the plate b out from between the ribs a³, a²,
the ends of the segmental hub 61, see Figure 4, have been provided with prongs 24,
one at each side, which prongs enter pockets or spaces 25, formed in or at the ends
of the segmental part of the hub a¹.
The lug 13 has shoulders at its rear side which enter behind lips 26, see
Figures 1 and 6, formed near the junction of the ribs a³ with the disc a opposite
the opening 12.
When the plate b is to be applied to the head a, the screw d is turned nearly
out from the ear d, so that the lug 13 may enter the space 10 between the ribs a²,
the outer end of said space 10 being large enough to permit the entrance of the
said lug 13.
After the lug 13 has been passed into the outer end of the hole 10, so that the
rear side of the said lug is flush with the back of the disc a, the plate b is moved
radially toward the centre of the beam, such movement causing the lug to slide
behind the lips 26, and at the same time the prongs 24 enter the pockets 25, and
thus placed in position, the screw is turned in far enough to keep the lug 13 in
engagement with some part of the lips 26, and in this condition the plate b, by any
lateral movement of the head a, can not be pushed or pulled laterally out from
between the ribs a³.
The beam outside of the head or flange has applied to it a metallic friction ring f,
the said ring having an annular groove to receive within it a friction strap of metal
or other usual material commonly used in connection with let-off and other beains.

Invention, and in what manner the same is to be performed, I declare that what
