Improvements in Warp Beaming Machines.
I, JOHN FINLAY, of 1 Prospect Terrace, Broughty Ferry, in the County of
Forfar, North Britain, and of Hastings, Serampore, Bengal, India, 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, that is to say:-
°
My said invention has for its object to improve the construction and operation of
warp beaming machines; and comprises special mechanism for driving the beam
in a manner to adequately and satisfactorily suit the increasing diameter of the
wound warp; also special mechanism for connecting the beam with the driving
mechanism; and appliances for supporting the beam and for facilitating its removal
when filled.
A beaming machine as made with my improvements is represented on four
accompanying sheets of explanatory drawings which are hereinafter referred to in
particularly describing the improvements.
Figure, 1, on Sheet, 1, of the drawings is a front elevation of the machine,
Figure, 2, Sheet, 2, is a left-hand side elevation, Figure, 3, Sheet, 3, is a right-hand
side elevation; and Figures, 4, 5, and 6, on Sheet, 4, are a front elevation and a
plan of some parts not well seen in the other figures.
In these drawings the same reference letters and numerals are used to mark the
same or like parts wherever they are repeated.
The framing of the machine consists mainly of end frames or gables, A, connected
by longitudinal bars or rails, B1, B2, B3, and the driving power is communicated
by means of a belt to a first-motion shaft, Ć, having on it fast and loose pulleys, C 1,
and carried by brackets at the upper part of the machine. On the shaft, C, there
is fitted with a groove and key a frictional pinion or pulley, D, made with a grooved
boss, D1, and which is moved along the shaft, by a yoke or cross bar, D 2, the
middle of which is made with a bridge to pass over the pulley boss, and with parts
projecting into the groove of the boss. The yoke, D 2, is fixed to two longitudinal
bars, D3, which are fitted to slide in guide eyes in brackets, D4, and which have
fixed to them outwardly projecting studs, D5, carrying anti-friction rollers,
engaging in and acted on by inclined slots, K 6, in vertically moving plates, K 5,
hereinafter referred to. The pulley, D, acts upon a horizontal disk, E, upon a
vertical shaft, E1, which by means of a pair of bevil wheels, E 2, and spur
wheels, E3, E 4, and E 5, drives a short shaft, F, with which the beam, G, is
coaxial when in position to have the warps wound upon it. By means of the
frictional pulley, D, and disk, E, the number of revolutions per unit of time
imparted to the beam, G, gradually varies as the diameter of the wound warps
increases, in such manner that the surface velocity of the warps in winding on
remains practically uniform, the variation being effected by the movement of the
frictional pulley away from the centre of the disk.
When the beam, G, is in position in the machine it rests with its drag
pulleys, G 1, bearing on concave parts, G 2, of horizontal bars, G 3, the ends of
which engage in notches in brackets, G4, fixed to slides, G 5, movable vertically
on fixed guide standards. The slides, G 5, are held up to hold the beam in working
position by eccentrics, G 6, on a shaft, G 7, actuated through wormwheel and
bevil-wheel gearing, G 8, from a vertical shaft, G 9, having a handwheel at its
upper end. The bearing parts, G 2, of the bars, G 3, are fitted with brass or anti-
friction metal pieces to diminish the friction of the beam when turning. When a
beam, G, has been filled, a truck, H, is brought under it, and the carrying
bare, G 3, are lowered by means of the mechanism just described, until the beam

page_text: rests on the truck, and the bars, G 3, are clear of it and can be removed. When
an empty beam has been placed in position by having the bars, G 3, placed under
its drag pulleys, G 1, and raised so as to lift it off the truck it is connected to the
driving shaft, F, by a coupling piece, F 1, fitted to the shaft with a groove and key,
and made with projecting prongs, which enter sockets in the face of the drag
pulley. The coupling piece, F 1, is moved into or out of the position in which it
engages with the beam by means of a lever, actuated by means of a screw and
hand wheel acting in groove formed around the boss of the coupling piece but not
shown.
The warps shown by peculiarly dotted lines, J, are, as usual, drawn off bobbins
or spools carried on angular frames, from both sides as indicated in the drawings,
or it might be from one side only, being led under and over fixed bars, J 1, J2,
and round a roller, J 3, or cylinder, J 4, onto the warp beam, G, the warps from
one side entering on the beam at its top, and those from the other side reaching the
beam at its bottom. As the warps are being wound upon the beam, G, they are
pressed upon and condensed by a roller, K, which rests upon them. This pressing
roller, K, has its end journals in bearings in the lower ends, K1, of vertical
bars, K 2, fitted at their upper ends for carrying weights, K 3, and slotted for the
passage of the first-motion shaft, C. As the beamed warps increase in diameter the
pressing roller, K, rises and is guided in its ascent by fixed guide brackets, B 4,
into the guide slot of which the roller journals project. The lower part of one of
the vertical bars, K 2, is made with diverging arms, K 4, to the outer end of which
are fixed vertical plates, K 5, moving vertically in contact with the top longitudinal
frame bars, B 1. These plates, K 5, are made with inclined slots, K, which act on
the studs, D5, herein before described as fixed on the sliding bars, D3, of the
yoke, D2, which moves the driving pulley, D, along the first-motion shaft, C. The
said slots, K 6, are inclined in such a direction that as the beamed warps increase in
diameter and the pressing roller, K, rises, and with it the plates, K 5, they cause
the driving pulley, D, to move towards the outer edge of the disk, E, thereby
causing the warps to be drawn onto the beam at a practically uniform rate
notwithstanding the increase in the diameter of the beamed warps.
The vertical bars, K 2, which hold the pressure roller, K, are formed with or
have fixed to their backs, as shown in Figure, 2, toothed racks, L, with which gear
pinions, L1, on a longitudinal shaft, L 2, and on this shaft there is fixed a ratchet
wheel, L3, a pawl engaging with which retains the bars, K 2, in any position to
which they may be elevated. The shaft, L 2, has also fast on it a spurwheel, L 4,
with which gears a pinion, L 5, on a short shaft having a handwheel, L 6, on it.
Any parts of the machine not herein specially referred to are to be understood
to be constructed as in existing warp beaming machines.
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 :
1. The improved warp beaming machine the parts of which are combined and
operate substantially as herein before described.
2. The driving of the beam by means of a disk actuated frictionally by a driving
pulley automatically moved towards the edge of the disk as the diameter of the
beamed warps increases, the parts being arranged and operating substantially as
herein before described.
3. The appliance comprising the coupling piece (F 1) for connecting the driving
gearing to the warp beam substantially as hereinbefore described.
4. The combination of the beam-supporting bars (G 3) with the parts for raising
and lowering them substantially as herein before described.
