IMPROVEMENTS IN APPA- RATUS OR MEANS FOR COLORING CAPSULES
Year: 1879

page_text: LETTERS PATENT to Edouard Belmer, of Cambridge Terrace, Islington, in the
County of Middlesex, Engineer, for the Invention of "IMPROVEMENTS IN APPA-
RATUS OR MEANS FOR COLORING CAPSULES."
Sealed the 3rd June-1879, and dated the 18th March 1879.
PROVISIONAL SPECIFICATION left by the said Edouard Belmer at the Office
of the Commissioners of Patents on the 18th March 1879.
EDOUARD BELMER, of Cambridge Terrace, Islington, in the County of Middlesex,
Engineer, "IMPROVEMENTS IN APPARATUS OR MEANS FOR COLORING CAPSULES."
My Invention relates to the coloring of capsules, and consists of improved appa-
ratus or means for performing that operation in a ready and efficient manner.
According to one mode of carrying out my Invention as applied, for example, to
the production of vertical stripes upon capsules, I employ a stencil tube formed
with a spring action so as to be capable of contracting for the reception of the
Capsule, and of expanding for its release, and fitted with a catch for retaining it in
its contracted position.
In coloring capsules with the aid of this apparatus the capsule having been
placed in the tube the latter is contracted and secured, and the color is then applied
to the exterior of the tube by means of a roller, the portions of the capsule which
are left exposed by perforations or openings in the tube having the color thus
imparted thereto.
According to another modification I dispense with the spring action and retain
the capsule in the stencil tube by frictional contact, and I employ an end pusher
for the expulsion or release of the capsule.
When it is required to color corrugated capsules I employ stencil tubes of the
required shape, and apply color to the parts left exposed by the perforations or.
openings in the tubes in the manner hereinbefore described.

the said Edouard Belmer in the Great Seal Patent Office on the 21st August
1879.
EDOUARD BELMER, of Cambridge Terrace, Islington, in the County of Middlesex,
Engineer. "IMPROVEMENTS IN APPARATUS OR MEANS FOR COLORING CAPSULES."
My said Invention relates to the coloring of capsules, and consists of improved
apparatus or means for performing that operation in a ready and efficient
manner.
According to one mode of carrying out my said Invention as applied, for example,
to the production of vertical stripes upon capsules, I employ a stencil tube formed
with a spring action so as to be capable of contracting for the reception of the
capsule, and of expanding for its release, the said tube being also fitted with a
catch for retaining it in its contracted position. In coloring capsules with the aid
of this apparatus the capsule having been placed in the tube the latter is contracted
and secured, and the color is then applied to the exterior of the tube by means of
a roller, the portions of the capsule which are left exposed by perforations or
openings in the tube having the color thus imparted thereto.
According to another modification I dispense with the spring action and retain
the capsule in the stencil tube by frictional contact, and I employ an end pusher.
for the expulsion or release of the capsule.
And in order that my said Invention may be fully understood I shall now proceed
more particularly to describe the same, and for that purpose shall refer to the
several Figures on the annexed Sheet of Drawings, the same letters of reference
indicating corresponding parts in all the Figures.
Figure 1 of the accompanying Drawings represents a side elevation of a stencil
tube for coloring capsules constructed according to one modification of my said
Invention; Figure 2 is a horizontal section and Figure 3 a plan of the same, the
tube being represented as contracted in Figure 2 and expanded in Figure 3;
Figure 4 represents a vertical section of a stencil tube for coloring capsules con-
structed according to another modification.
Referring to Figures 1, 2, and 3, A is the tube, having perforations or openings a
corresponding to the stripes or pattern of the capsule to be produced. This tube is
formed with a spring b, which when free maintains the tube in its open or expanded
condition, as shewn in Figure 3, but by the act of exercising pressure upon the
spring the tube may be contracted, in which condition it is maintained by a spring*
catch c, as indicated in Figure 2.
In coloring capsules with the aid of this apparatus the tube being in its open or
expanded condition, as indicated in Figure 3, the capsule is placed therein and sup-
ported by a stop d. The tube is then contracted and secured by its spring catch c,
as shewn in Figure 2, and color is applied to the exterior of the tube by means of
a roller, as denoted by dotted lines at d¹, in Figure 2, whereby the portions of the
capsule which are left exposed by the perforations or openings a in the tube have
the color imparted to them.
Where, owing to the peculiar design of the capsule, it is necessary to economize
space the spring action may be dispensed with and an end pusher e be employed,
as shewn in Figure 4.
During the operation of applying the color the capsule is retained in the tube by
frictional contact, and when the color has been applied the capsule is expelled or
released by the act of depressing the extremity e' of the pusher, and forcing it into
the position shewn by dotted lines.
When it is required to color corrugated capsules I employ stencil tubes of the
required shape, and apply color to the parts left exposed by the perforations or
openings in the tubes, in the manner herein before described.

page_text: Having now described and particularly ascertained the nature of my said Inven-
tion, and the manner in which the same is or may be used or carried into effect, I
would observe in conclusion that what I consider to be novel and original, and
therefore claim as the Invention secured to me by the hereinbefore in part recited
Letters Patent is,-
The employment in coloring capsules of stencil tubes fitted with a spring action
or end pusher, substantially as hereinbefore described.
In witness whereof, I, the said Edouard Belmer, have to this my Specification
set my hand and seal, the Twenty-first day of August, One thousand eight
hundred and seventy-nine.
EDOUARD BELMER,
