Improvements in Twisting Machines.
I, ADOLPHI HAENICHEN, of No. 669, East Twenty-Third Street, in the City of
Paterson, County of Passaic and State of New Jersey, U.S.A., Silk Manufacturer,
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 twisting machines or spinning frames, and it consists
in the improved spinning machine, and in the combination and arrangement
of its various parts, substantially as will be hereinafter described and finally set
forth in the claims.
The invention is fully illustrated in the accompanying drawings, wherein
corresponding letters of reference indicate like parts, and wherein,
Fig. 1 is a front view of one end of my improved spinning frame, that is
to say,
the end where the power for driving the machine is taken into tho
same;
Fig. 2 is a view in sido elevation of a portion of that end of my spinning
machine which is shown in Fig. 1;
Fig. 3 is a front view of the other end of my improved spinning machine;
Fig. 4 is a view in side elevation of a portion of that end of the machine
which is shown in Fig. 3;
Figs. 5 and 6 are, respectively, a view in aide elevation and a top plan view
of a certain spindle-support, certain portions of said support being shown in
section in Fig. 5; and,
Fig. 7 is a sectional view of one of the sheaves over which the belt for
rotating the spindles extends, and also of the bearing-bracket for said sheave.
In said drawings, a designates two or more uprights or standards which are
connected and braced by centrally disposed rails or beams b, c, that extend
throughout the length of the machine, the one being situated above the other.
Below each of said beams b, c, is disposed a pair of spindle-rails d, the one
near one side and the other near the other side of the machine. Upon each
of these rails are sustained the spindle-supports, each of which supports con-
sists of a two-part bracket, the one of which e is secured to the rail by a bolt f
and the other of which 9, is substantially H-shaped and carries the spindle h,
the whirl of the spindle being disposed between the two arms of the H-shaped
bracket g, so that the power which rotates the spindle is directed substantially
centrally of the entire device; the two members are connected by a spring j
which is coiled about the pivoting bolt for said members and bears at its
and about
ends against each of the latter. In the upper arm of the bracket
the spindle is formed a ball-race in which are disposed anti-friction balls /
that are held in place by a plate m secured upon said arm over the ball-race
and penetrated by the spindle; in the lower arm of the bracket, that is to say,
the one in which the spindle is stepped, is arranged a cylindrical block n which

page_text: is tapered at its lower end, as at o, and fits a corresponding recess in said arm,
and which at its upper end is provided with a conical recess receiving the
tapering lower end of the spindle.
Upon the beams b, c, are mounted pairs of brackets q. the central portion of
each of which is seated and secured upon the top of the beam while its extremi-
ties project therefrom in opposite directions and are formed with sockets r, s.
Beneath the projecting extremities of the brackets q and extending parallel to
the beams b, c, are journalled, in suitable bearings provided in the several
uprights a, shafts t, each of which shafts carries a series of rollers . designates
the receiving bobbins which are adapted to bear against and be driven by the
rollers ; when thus rotated they are adapted to be seated in the sockets r of
the pairs of brackets g, but when out of use, they are adapted to rest in the
sockets of said brackets.
are supports which are secured to the inner faces of the several uprights,
substantially in the horizontal plane of the beams and c, said supports carrying
rails provided with eyeletsy and also serving to sustain the longitudinally
movable thread-guide-carrying rails, the upper extremity of each support
being recessed to receive the rail, as most clearly shown in Fig. 1.
Tpon each of the rails is mounted a series of thread-guides e, which thread-
guides, when the rail is reciprocated, feed the thread taken off the several
spindles and extending through the eyelets y, uniformly onto the receiving
bobbins u.
From one end of the frame of the machine extends a rest, upon which
are mounted bearing blocks e, the main drive-shaft being journalled in said
blocks and maintained therein by bridge-pieces a which are bolted to the
blocks and pass over the shaft. One end of said shaft carries fast and loose
pulleys and a³, while its other end carries a fly-wheel a Intermediate of
its bearings, said shaft carries a worm-wheel whose teeth engage the teeth
of a worm that is secured upon a vertical shaft . The lower end of this
shaft is stepped in a bearing-bracket 6 which projects upwardly from the end
upright of the machine frame, while its upper end is journalled in another
bearing-block, also projecting from said upright and disposed near the upper
end thereof. 65 designates pairs of supports that are mounted upon the rest
and sustain a horizontally reciprocating bar el carrying a fork one end of
said bar being extended as far as the pulleys and a3 and the said end of the
bar carrying said fork. is a lever that is fulcrumed at its lower end in the
rest and is provided with a longitudinal slot with which engages a bolt e
that projects from the bar el, said lever carrying another and spring-actuated
lever or pawl whose lower end is formed with a lug that is adapted to
engage either of two notches formed in a segment that is secured upon
the rest. The mechanism comprised in the lever the bar and the fork &,
constitutes a belt-shifter, and by securing the lug of the pawl or lever
either of its notches in the segment, the belt, after being shifted, may be
maintained in operative engagement with either of the two pulleys a³ or n³.
The shaft may have ball- or any other suitable anti-friction bearings; it
carries two sheaves each of which is disposed in the horizontal plane of a
corresponding set of spindles.

in
Projecting from the upright at the end of the machine opposite to that
where the main driving-mechanism is disposed is a pair of other bearing-
brackets me. One of these bearing-brackets is shown in detail in Fig. 7, where
it is shown as comprising two members, the one m¹ being secured to the frame
and provided with a longitudinal slot m² and the other m³ resting on said
first-named member and having a bolt m' which penetrates the slot and whereby
said last-named member may be held in any position to which it is adjusted.
Adjustment between the members is effected by a set-screw m³ whose threading
engages a lug on the member m² and which works in an upwardly extending
notch formed in a lug n³ that projects downwardly from the member m³,

page_text: said set-screw having a pair of collars a¹ engaging opposite sides of the lug.
Projecting upwardly from the member is a vertical stub-shaft n³, which
affords a journal for a sheave o, between the lower end of whose hub o and
the member m are anti-friction balls ³, said sheave being kept in position by
a collar secured above it upon the shaft.
The sheaves o, like the sheaves, are disposed in the planes of the respective
sets or groups of spindles, and connecting said sheaves are continuous bands or
belts o. All of the whirls and both the upper and lower sets of spindles bear
against these belts, being maintained in effectual contact therewith by the
springs g of the supports which carry the spindles.
This
The vertical shaft carries worms o³, each of which is disposed above a
worm 6, and with each of said worms engages a worm-wheel pl
worm-wheel is journalled upon a stub-shaft which penetrates the lower cud
of an L-shaped frame, said worm-wheel being spaced from the end of said
frame by a sleeve on the stub-shaft. is a bracket secured to the outer
face of the upright a and provided with two upwardly projecting arms having
horizontal slots in which the stub-shaft may be adjustably and firmly set (by
means of a nub screwed onto its innermost end, for instance, and taking against
the rear face of the bracket) according to the diameter of the worm-wheel which
said stub-shaft carries. Said L-shaped frame carries another stub-shaft which
is jou nalled therein and which carries rigidly connected pinions,, the
pinion being in engagement with a gear that is secured upon the end of
one of the shafts t. It should be remarked that the L-shaped frame and the
gearing which it carries is duplicated, so that power may be transmitted from
the worm to each of the shafts. The pinions are adapted to be removed
80 that by changing them for others of different diameter, variations in the speed
of the shafts may be secured. For this purpose, the L-shaped frames are
rendered adjustable about the stub-shafts by means of bolts that penetrate
It will be seen that the
slotted are-shaped guides secured to the upright
upper end of the L-shaped frame affords a handle for operating it. The lower
end of this frame is simply made adjustable in the slotted arms so that, when
necessary, the gearing can be disconnected: if desired, however, this adjusting
means may be made use of in changing the pinion for other pinions of
different diameter, as in the case of the pinions
In order to reciprocate the thread-guide-carrying rods, levers . adjustably
fulcrumed in brackets projecting from the upright a which supports the
brackets for the sheaves o¹, are provided, said fevers having pins which
engage vertical slots in T-shaped projections f³ that are secured to the
adjoining ends of the thread-guide-carrying rails. The levers are normally held
inwardly by spiral springs which connect them with the upright, and they
are vibrated by cams journalled ou stub-shafts projecting from said upright,
a gear being connected to each cam and engaging a pinion on
corresponding shaft t.
the
The device shown in Figs. 3 and 4 and which surmounts each stub-
shaft for the sheave o' is simply a lubricating device with which communicates
a duct penetrating the shaft and deflected at its lower end so as to conduct
the lubricant to the bore of the hub of the sheave.
of
I have provided a spring clip which projects from the stationary member e
of the two-part bracket outwardly beneath the other or movable member
said bracket and which has a hook-shaped free eud that is adapted to engage
one side of said last-named member in an obvious manner so as to hold it at
right-angles to the spindle rail and thus prevent operative contact between the
spindle whirl and the belt in case it is desired to stop the action of any
individual spindle.
In operation, the belt, which the pulleys a² and a³ are adapted to receive,
being thrown over by the belt-shifting mechanism from the loose to the fast
pulley, the shaft o' will be rotated, and power transmitted therefrom, through

page_text: the gearing comprised in the worm band worm-wheel a³, to the vertical
shaft 6. As this shaft rotates, the belts of which it drives revolves the several
sets of spindles, said spindles being held in effective contact with the belts in the
manner above set forth. At the same time, through the gearing comprised in the
worms, the gears and the gearing which the frames carry, the rotary
motion of the shaft is transmitted to the several shafist whereon are mounted
the rollers u. These rollers of course rotate the several sets of bobbins, so that
as the spindles are revolved by the belts so as to twist the threads, the latter
are taken off of said spindles and wound on the bobbins.
It will be observed that since the barrel or body-portion of each bobbin,
that is to say, that portion thereof upon which the thread is wound, directly
bears on the driving rollers u, the tension which the bobbins exert on the cops
on the spindles his maintained constantly uniform, because, though the
diameters of the cops on each bobbin and the corresponding spindles are con-
stantly changing, as the former increase in size, the speed of rotation at which
each bobbin is revolved by its roller, gradually reduced.
Of course, as the several shafts revolve, the levers are caused to vibrate,
by virtue of the action of the gearing, and the cams fo, thus reciprocating
the thread-guide-carrying rails and so laying the threads evenly on the barrels
of the several bobbins.
It will be apparent that it is only necessary in order to tighten up the
belts, to release the bolts m and manipulate the set-screws m³, 80 as to shift
the sheave-carrying members of the brackets m inwardly and outwardly with
roference to the machine.
