Improvements in or applicable to Addressing Machines.
A communication from abroad by WILLIAM P. BOUSALL, of Toronto, Canada.
I, CHARLES AUBREY DAY, of 321, High Holborn, London, Middlesex, England,
Fellow of the Institute of Patent Agents do hereby declare the nature of the said
invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
The object of the invention is to design a simply constructed addressing machine
with positive inking mechanism and otherwise so arranged that the type-blocks may
be readily changed, and all other parts easily adjusted; and it consists, essentially, of
a series of type-blocks or plates having their ends formed to fit onto endless belts
passing around and supported by two rollers journaled opposite to each other upon a
longitudinally reciprocating frame, one roller being made angular in shape and
arranged in connection with mechanism by which the said roller is caused to make a
quarter turn at each stroke of the longitudinally-moving frame, and thus moving a
type-block or plate into position immediately in front of the said roller, where it
remains until it has performed its function of printing when the revolving of the
said rectangular roller moves the said type block or plate and replaces it by the type-
block or plate next to it; the whole being constructed in detail substantially as
hereinafter more particularly explained.
Figure 1. is a perspective front view of the improved addressing machine.
Figure 2. is a similar view from the opposite side of the machine.
Figs. 3, 4, 5 and 6) are enlarged details of the mechanism by which the rectangular
roller is held in position while the type is printing; and caused to revolve for the
purpose of changing the type-blocks or plates.
Figure 7. is a detail of the rectangular or operating roller, showing a metal type-
plate held in position on endless ends.
Figure 8. is a detail of a wooden type-block or plate, showing its ends formed to
fit onto endless bolts.
Figure 9. is a detail of metal type-plate.
In the drawings, like letters of reference indicate corresponding parts in the
different figures.
A, represents a frame, on one end of which is journaled a round roller, shown in
dotted lines and at its opposite end a rectangular roller. B. The type-blocks or plates C
are made as shown in Figures 7 or 8. When made as shown in Fig. 7 the type-
blocks consist of a metal plate having its ends bent as shown to fit around the endless
cords or belts D, which cords are carried around the rollers journaled at each end of
the frame A.
When the type-blocks or plates as shown in fig. 7 are used, the rectangular
roller B, has a projection a, formed on each side, on which the type-blocks or
plates C fit.
When the said type-blocks or plates are made as shown in figure 8 an incision b,
is made at each end of the blocks or plates into which the endless belts D fit.
When the blocks or plates shown in Figure 8 are used it is not necessary to use
the projection a, on the roller B.
'
E is a segmental-plate rigidly secured to the frame A, and formed so as to journal
upon and be guided by rods F and G, the rod F being held by the arms H, which
project from the post I, and the rod G, being supported by suitable brackets fastened
to the said post I. A handle J connected to or forming part of the plate E, projects
beyond the rod F, and is used to impart motion to the frame A. The spring K,
which is fastened to the upper arm H, and passes around a pin projecting from the
plate E assists in imparting the necessary movement to the frame A.

page_text: L is a guide-plate located and shaped substantially as shown in the drawing, so
that at the upper and lower portion of the stroke of the frame A, the side of the
block M, shall rest against the said plate while the centre portion of the said plate is
set in to permit the revolving of the said block.
On reference to Figs. 3, 4 and 5, the manner in which the rectangular roller B, is
caused to revolve will be understood.
In fig. 3 the frame A is shown as pressed down, so that the type block or plate C,
is held against the printing block N. It is of course necessary that the face of the
type-block or plate C shall rest perfectly flat upon the printing block N, and to
ensure this end the guide-plate L, is located and shaped so as to form a guide against:
which the side of the block M, must fit, as indicated in Figure 3.
When the frame A, is permitted or caused to move from the printing block N, the
upper outer notch d, made in the block M, comes in contact with the end of the
spring plate O, which action causes the block N, to revolve, as indicated in Fig. 4
carrying with it the rectangular roller B, which in its turn moves the string of type-
blocks C, the width of a single block, so as to bring the type block next to the one
which has just printed into position for the next stroke.
.
On reference to Figure 5 it will be observed that when the frame A, has reached
the top of its stroke, the block M, is held between the guide-plate L, and spring-
plate O, thus ensuring the perfectly horizontal position of the bottom type-block C, on
the downward stroke of the frame A.
In order to case the blow against the upper end of the guide-plate L, a cushion e,
of rubber or other compressible material is placed on the upper end of the said guide-
plate, as shown.
With the view of inking the type-blocks C, an inking roller P, is journaled, ‘as
indicated,. upon fingers pivoted in the end of the forked support Q, the upper
end of which support is pivoted upon the pin R, extending from the frame H
as shown.
.
On each side of the frame A, a pin S, projects for the purpose of fitting into curved
slots formed in the curved arms T, which project from and are fixed to the forked
support Qas shown.
Owing to the connection described, between the frame A, and the forked support Q
which carries the inking roller P, each upward stroke of the frame A, causes the
inking roller P, to pass below the frame A, as indicated in figure 1, where it acts
against and applies ink to the bottom type-block, while upon the downward stroke
of the frame A, the said inking roller is carried clear of the said frame, as indicated
in Fig. 2.
. By carrying the inking roller P, upon fingers pivoted on the end of the forked
support Q, the said. inking roller may be readily adjusted so as to properly act
against the type-blocks, the spring U, imparting to the said inking roller a suitable
spring tension.
In practice it is found that when the string of type-blocks is revolving, the
inking roller P, does not supply sufficient ink or distribute it over the type as
evenly as desirable. An inking pad V, is therefore suspended in front of the
frame A, by a spring plate W, attached to a spindle X, held by a plate Y, pro-
jecting from the frame A, as indicated. The spring plate W, holds the inking pad V;
against the type with sufficient pressure without interfering with the free movement
of the type-blocks, and as the type-blocks pass the said pad the ink is evenly
distributed over the type.
As it is sometimes necessary to obtain a number of impressions from the same
type-block a plate Z, is pivoted as indicated, below the spring-plate O, and
when it is wished to thus use a single type-block the plate Z is adjusted to the
position in which it is shown in Figure 6, thus separating the spring-plate O;
from the block M, which block will then slide up and down the plate Z, without
revolving.
It will be observed that whether the type-blocks C, have incisions b, made in
their ends to receive the endless cords or belts B, or whether they are made of

page_text: sheet metal with ends formed to fit around the endless cords or belts D, they are easily
detached so that any one type-block C, may be easily and independently removed and
replaced by another type-block.
Though merely a handle J is shown for the purpose of operating the frame A, it
will, of course, be understood that a treadle motion might easily be applied to the said
frame for the purpose of operating it.
The letters on the type-blocks C may advantageously be made of vulcanized
rubber; as this form of type is very convenient for the purpose for which the
invention is adapted, but such and any other part of the improved machine may be
made of any suitable material.
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. A series of type blocks or plates C, having incisions or loops made in their ends
in combination with the endless belts or cords D, fitted into the said incisions or loops
and carried around rollers located at each end of the frame A, substantially as and for
the purpose specified.
..
2. In an addressing machine, a rectangular roller B, journaled on the end of the
reciprocating frame A, and having a string of type-blocks C, carried around it the
block M, fixed to the spindle of the roller B, in combination with the plate O,
substantially as and for the purpose specified.
3. In an addressing machine, a rectangular roller B journaled on the end of the
reciprocating moving frame A, and having a string of type blocks C carried around
