Improvements in Apparatus for Printing Carpet Yarns.
I, CHARLES LUDWIG HORACK, of No. 50 Livingston Street, Brooklyn, Kings
County, State of New York, United States of America, Civil and Mechanical
Engineer, do hereby declare the nature of my 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 refers to improvements in apparatus for printing carpet yarns>
and particularly to such as are used in the manufacture of tapestry and velvet
carpets and are described in William Shaw's Patent for Great Britain No. 14,422
of 1895.
The objects of the improvements are to facilitate the alternate use of equalizing
and rubbing appliances of different widths mounted upon the same springs without
being compelled to disorgauize the portions of the apparatus which directly support
such appliances and particularly without being obliged to displace or in any way
handle the supporting springs, while so exchanging such appliances.
In applying the improvements, it is preferable to make use of an apparatus as
described in said Patent No. 14,422 of 1895, and of equalizing and rubbing
appliances substantially as illustrated in Figures 5 to 10 inclusive, and more
particularly in Figures 9 and 10 of said patent.
In the accompanying drawings, Figure 1 represents a side elevation of
equalizing and rubbing appliances constructed and mounted according to this
invention, while Figure 2 is a ground plan of Figure 1 showing such appliances
made of comparatively great widths properly mounted, part of the rubber 70
appearing broken away. Figure 3 is a vertical cross section along line A, B, C,
D, E, F, G in Figure 2, and Figure 4 a vertical section along line A, B, C, D,
E, H, in Figure 2 a narrow equalizer and rubber however appearing substituted
for the corresponding wider appliances above referred to.
Corresponding figures of reference throughout the different views refer to
corresponding parts. 65 is a platform on the upper end of a post 29, upon which
are mounted three vertical studs 78, 78 and 79. Springs 721, 75', 71' and 74' are
U-shaped leaf springs, their perforated ends being held in contact with and
permitted to slide freely along posts 78 and 79, respectively. Resting upon the
upper ends of springs 741 and 75' and underneath the upper ends of springs 711
and 72 a T-shaped base 11 is so inserted that its perforated lugs 12, 12 are
adapted to freely play along said posts. 70 is a rubber, T-shaped in ground plan
and detachably secured to said base, proper slots 13, 13, opening rearward being
provided for such purpose near the lower extremities of said rubber are adapted to
engage with corresponding studs 14, 14, which are provided with heads 15 and
capable of being screwed down slightly, if desired, so as to firmly hold the rubber
to base plate 11. 16 is a base plate for supporting the equalizer 66 which is
U-shaped in formation. Said plate rests upon the upper ends of springs 711
and 72 and has perforated lugs 17 which also are adapted to play along posts 78
and 79. Equalizer 66 which may also be provided with a lateral rubber 88 has
rear lugs 18, 18, provided with slots 19, opening rearward and two side lugs 20, 20.
21, 21 are studs provided with heads 22 and adapted to be screwed downward
slightly to secure the rear end of the equalizer in its proper position. Lags 20, 20
may be secured to base plate 16 in a like manner, but it is preferable to hold the
same in position by screws 23, so as to secure said equalizer more firmly to its base.

page_text: 24 is a projection which may be provided on the underside of base 11, adapted to
come to rest upon platform 65 before the supporting leaf springs can become
compressed unduly, while the studs and screws above referred to are being screwed
downward.
The equalizer and rubber while in contact with the yarn will travel in the
direction of the arrow indicated in Figure 1 there being in consequence constantly
a rearward pressure exerted upon such parts, which pressure will have a tendency
to enforce close contact between the shanks of the securing studs above referred to
and the forward portions of the corresponding slots with which they engage.
When one set of cqualizers and rubbers is to be superseded by another one
screws 23 will have to be withdrawn and after loosening the studs which holl the
equalizer and rubber in position the two may be driven forward together until
detached, a knob 25 being provided at the rear end of the equalizer so that the
portions intended to engage with the yarn on the drum may not receive the blows
of a hammer applied for such purpose. 26 are washers on top of posts 78 and 79,
and 27 screws entering the heads of such posts through said washers and preventing
the equalizer and rubber and the supporting leaf springs from becoming detached
from said posts, and it will be seen that if rubber 70 and its supporting base were
consolidated in one piece it would still be possible to detach equalizer 66 fron
posts 78, 79 and rubber 70 from its supporting base without being obliged to
interfere with any of the supporting leaf springs.
As, ordinarily, equalizers are of about double the width of the color wheel in
whose path they follow, and as such equalizers and rubbers are generally intended
to cover the streak of coloring matter which at the time is being applied to the
yarn, and in addition an adjoining streak previously made the central planes of the
equalizer and of the color wheel will not coincide. In Figures 2, 3 and 4
X X represents the central plane of the color wheel and Y Y that of the
accompanying equalizer.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
1. The construction and employment of the improved apparatus for equalizing
coloring matter on yarns comprising a series of guide studs, a U-shaped equalizer,
springs supporting the same, a base underneath the movable portions of said
springs adapted to support a rubber, and springs underneath said base, all adapted
to play along said studs, and a rubber detachably mounted on its base and operating
between the arms of the equalizer.
2. The construction and employment of the improved apparatus for equalizing
coloring matter on yarn comprising a series of guide studs, a base for a U-shaped
equalizer, springs supporting said base, a base adapted to receive a rubber
arranged underneath the movable portions of said springs, and springs underneath
said second base, all adapted to play along said studs, and a U-shaped equalizer
detachably mounted on the upper base and a rubber detachably mounted on the
lower basc.
3. The construction and employment of the improved apparatus for equalizing
coloring matter on yarn and embodying a spring supported base, and a rubbing
appliance detachably mounted thereon and adapted to slide along said base and out
of its operative position in the direction in which said rubbing appliance travels
while in contact with the yarn on a drum.
