J, WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake & Co, Patent Agents,
Southampton Buildings, in the County of Middlesex 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 heads for continuously drawing and twisting a sliver
of wool or cotton and consists in the construction and combination of parts as
hereinafter described.
This invention is fully illustrated in the accompanying drawing, in which,
Figure 1 is a view of one end of the device with a part broken away.
Figure 2 is a view of the same complete.
Figure 3 is a view of the opposite end of the device.
Figure 4 is a section upon the dotted line x x of Figures 1 and 2.
Figure 5 is a plan view of a detail.
Figure 6 is a top view of the complete device in operative position, with
sufficient of the supports and driving belts to show the relation of the parts.
Figure 7 is a perspective view of a frame containing a number of the improved
beads in position for use.
A B are two rubber faced rolls journalled in walls a b in a case C.
The roll A has permanent bearings, and is provided with a gear wheel D secured
to its axis or arbor outside of the wall b.
The roll B is held in close contact with the roll A. by means of a follower E,
forked to bear against opposite journals of said roll and provided with a spring H
interposed between its back and the inner wall of case C.
The journals of roll B are received in elongated alots in the walls a b, and the
action of the spring H is to always keep, through follower E, the surfaces of the
rolls in contact.
The point of contact of rolls A, B is, as shown, coineident with a transverse line
through the centre of the case C.

page_text: The outside posterior portion of the case C is reduced to leave a cylindrical outer
wall c and shoulder d, and fitted to come against the shoulder and bear upon the
surface c is a shell G provided upon its face opposite the shoulder d with cogs g, as
shown in Figure 5.
Beneath the gear wheel D and journalled between the wall b and case C is a
gear wheel F, arranged to engage with the gear wheel D and to intersect the
shoulder surface d as shown in Figure 3 so as to be engaged by the cogs g of shell G.
The shell G is held in its proper position relative to the case C by means of a
screw h the end of which passes into an annular groove i in surface c as shown in
Figure 4.
The outside of sections C G are provided with two grooves to receive the
belts I R.
M is a web upon the face of case C which web is perforated centrally and
depressed, as shown in Figures 2 and 4, and which keeps the roving in the proper
place between the rolls A, B, and also serves as a guard to protect the interior of the
head from dust and lint, which would otherwise soon clog up the inner mechanism.
O is a trumpet shaped surface within case C, having its apex close to the inner
surface of rolls A B, and its mouth coinciding with the rear end of case C, as seen
in Figures 3 and 4.
The interior configuration of case C given by the surface O and the web M not
only closes the case to shut out particles of flying matter from the gearing and
journals within said case, but preserves the end of roving from injury, and permits
it to be safely taken to a bobbin out of line with the axis of the head.
The head when journalled as shown, in Figure 6, has the case C and shell G
driven by belts I, K, at different speeds, and it will be seen that the rolls A B,
beside their rotation on the axis of the head rotated by belt I, have rotation on
their axis by contact of the gear wheel F with the cogs of the section G, rotated
by belt K at a greater speed than the case C, so that an end of roving passing into
the head would be twisted and drawn simultaneously and so that the proportion
of the twist to the draw would depend upon the relative speeds of the sections C G
. of the head.
+
The main purpose of the invention has been to enable the ends of roving to pass
continuously to the bobbins from the condenser, and thereby avoid the necessity of
the manipulation and mechanism common with mules and Jack-frames.
In Figure 7 a frame containing ten heads is shewn.
The ends m are represented as coming from the condenser (not shown) and after
passing through the guide-rolls L, are drawn and twisted by the heads and from
them pass directly to the bobbins P, indicated in the drawing.
The relative speeds of the sections of the heads is governed by cone pulleys T T,
with a belt Y connecting said pulleys. This belt may be shifted by hand, or by
any ordinary form of belt shifter.
The spindles of said pulleys T T rotate pulleys V, W having respectively the
endless belts I, K, which belts rotate the sections C, G of the heads, so that the
positive speed of the heads and relative speed of their sections is determined by
the position of belt Y upon its cone pulleys.
By means of a head so constructed with rubber faced friction rolls and with
conical ends, as shown, a sliver is evenly twisted and drawn and preserved from
abrasion as it enters and leaves the head, and by means of their arrangement in a
frame and the arrangement of cone pulleys and endless belts, the heads are effective
to deliver the roving without other intermediate mechanism, from the condenser to
the bobbins.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed as communicated to
`me by my foreign correspondents, I declare that what I claim is,
-
First. The improved drawing and twisting head consisting of a case C adapted
to rotate in bearings, two rubber faced friction rolls journalled in said case, a gear

page_text: wheel D in the axis of one roll, a gear F arranged to mesh with said gear wheel D
and having a part thereof projecting beyond the case C, funnel shaped guards M
and O secured to the ends of casing C and projecting inward nearly to the friction
rolls and gear wheels, and the shell G mounted so as to rotate on case C and
having a toothed surface engaging with the gear wheel F, substantially as
described.
Second. In combination, a series of drawing heads each consisting of one
cylindrical section carrying a pair of drawing rolls and another section rotatively
mounted thereon and having a gear wheel adapted to drive the drawing rolls
through intermediates; a frame on which said drawing heads are supported; two
endless belts I and K, one engaging the roll-carrying sections and the other
engaging the roll-driving sections of the drawing heads, and two shafts, each
bearing a cone pulley; and a belt pulley; the belts I and K, passing over the belt
pulleys respectively, and a belt connecting the cone pulleys, all substantially as
described.
