COMPLETE SPECIFICATION.
An Improved Combined Type-writer and Adding or Computing-
machine.
I, REGINALD HADDAN of the Firm of Herbert Haddan & Co. of 18, Buckingham
Street, Strand, London, Patent Agent do hereby declare the nature of this invention
a communication to me from abroad by Holmes Marshall of Cleveland, in the County
of Cuyahoga, and State of Ohio, United States of America, Manufacturer and in
what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
The invention relates to an improved combined typewriter and adding or
computing-machine and it consists, among other things, in the arrangement of the
adding or computing-machine below the typewriter and in view of the operator, a row
of laterally shiftable plungers arranged over the keyboard of the computing-machine,
and mechanism for each plunger for depressing said plunger and operatively connected
with the required operating key of the typewriter, so that the operation of said
typewriter key will simultaneously effect the operation of the computing machine's
key below said plunger.
The invention consists, also, in novel and meritorious features of construction, and
combinations of parts, hereinafter described and pointed out in the claims.
In the accompanying drawings,
Figure I is a front side elevation of a combined type-writer and adding or computing
machine, embodying the invention. Fig. II a left hand side elevation of the same.
Fig. Ill is a top plan in section, on line 3-3 Figs. I and II.
The type-writer A is suitably supported from legs B mounted upon the top C of a
table or desk. There are four legs B arranged in pairs located at the left hand side,
and right-hand side, respectively, of the machine.
The adding or computing-machine D is mounted upon the table-top or desk-top C
between the two pairs of legs, and sufficiently near the forward legs to enable the
operator to see the computing machine's sight holes d, through which the amount,
that is added and registered by said machine, is exhibited. Said sight holes are
arranged in a row, in the usual manner, widthwise of the top of the forward end of
the adding machine. The adding machine, in the case illustrated, is provided with
eight rows of operating-keys D', and said rows are arranged forwardly and rearwardly
of the machine. The two right hand rows of keys D¹ are instrumental in registering
cents, or fractions of a dollar, and the remaining six rows are instrumental in a
registering dollars. The third right hand row of keys D' is the unit row, and thence
to the left are the tens row, hundreds row, thousands row, ten thousands row and
hundred thousands row, in the order referred to.
A spiral spring D 2 confined upon the stem of each key D 1, between the key's
head and the top of the case of the adding machine, acts to retain said key in its
upper or normal position.
The construction and operation of adding, computing or calculating machines are so
well known by those skilled in the art, that further reference thereto, or a more
extended description thereof, is not considered necessary in this specification. Suffice
it to state, therefore, that any approved construction of adding, calculating or

page_text: computing machine is employed, and that the amount registered or added is exhibited
or visible through the sight-holes d of said machine; that keys D1 constituto the
operating keys of said machine; that the number and denomination represented by
any one of said keys are registered upon the depression of said key; that there are
nine keys in each row of keys, and that the keys of each row of keys, commencing
with the forward key, are instrumental in registering numbers 1, 2, 3, 4, 5, 6, 7, 8
and 9, respectively, of the denomination represented by said row of keys. Two
horizontal and parallel bars E E are arranged a suitable distance above and widthwise
of the adding machine, and are arranged a suitable distance apart between the rear
end and forward end of said machine. Bars E E are suitably supported from upright
arms or standards e rigidly secured to the case of the adding machine. A carriage G
extends between and is mounted upon and adapted to reciprocate endwise of bars E.
Said carriage is of any suitable construction and consists, preferably, of a frame
terminating at its forward and rear ends in any suitable number of sleeves or slides GL
slidably mounted upon bars of slideways E. A row of plungers H arranged forwardly
and rearwardly of the adding machine, and just above the latter's key-board, is
provided, and said plungers are adapted to depress the different keys, respectively of
any of the rows of keys of the adding machine. Plungers H are located directly
below carriage G, and each of said plungers is provided with an upwardly extending
stem, that has bearing in an upright box g of carriage G, and, a suitable distance
above said carriage, is provided with a head 1. A spiral spring / 2 confined upon
the stem of each plunger, between head 1 and the top of the plunger-carriage, acts
to retain said plunger in its upper or normal position. By the construction thus far
described, it will be observed that upon depressing any one of the plungers against
the action of the spring acting to retain said plunger in its normal position, when the
series of plungers are in position over any one of the rows of operating keys of the
computing machine, the key in said row of keys, that is below the plunger being
depressed, is depressed also, and thereby operated and it will, furthermore, be observed
that the plunger carriage can be shifted laterally in the one direction or the other, in
order to bring the plungers in position over any one of the rows of keys of the adding
machine. Mechanism is therefore, provided whereby the plunger carriage is shifted
from left to right, or from right to left, according as the paper carriage of the
type-writer, to which I will presently refer, is shifted from right to left, or from left
to right and I provide, also, mechanism for each of said plungers for depressing the
plunger and operatively connected with the key of the type writer that bears and
is instrumental in printing the numeral represented by the adding machine's keys
adapted to be depressed by said plunger, and hence, when it is desired to print a
column of amounts upon the paper carried by the type-writer's paper carriage, the
adding machine will, during the printing of said amounts upon the paper, add them
and display the sum at its sight holes, so that the operator is informed of and can at
once print the sum upon his paper, without delay.
A1 designates the operating-keys of the type-writer. Said keys are operatively
connected, in any approved manner, with different vertically tilting levers A2
operatively connected, in the usual manner, with the type-bearing-levers of the
type-writer. Mechanisms for establishing operative connection between the type
bearing levers of a type writer and the typewriter's operating keys, are so well
understood by those skilled in the art, that further reference thereto or description
of same in this specification, or illustration thereof, is considered unnecessary.
Suffice it to state, that the vertically-tilting levers A 2, that are instrumental as
already indicated, in operating the type-bearing levers of the type-writer, are
fulcrumed at one end upon a horizontally arranged rod A 3, (see Figs. I and II).
A series of bail shaped vertically tilting levers K, arranged between the typewriter
and adding machine, have their central members (see Fig. III) engaging grooves of
recesses 3 formed in the top and extending transversely of the heads of the different
plunger stems respectively. That is, the head 1 of the stem of each plunger H
upon its top, has a transversely arranged recess 3 engaged by the central member
of a vertically tilting lever K. Levers K are arranged in a row forwardly and

page_text: rearwardly and are fulcrumed at K1, at or near the forward extremities of their
end members, to forwardly and rearwardly extending bars, L rigid with legs A.
The foremost bail shaped lever is the shortest, and each of the remaining bail
shaped levers is somewhat longer than the next forward lever, and straddles, and is
fulcrumed a short distance rearward of, the next forward lever (see Fig. III) and
the lover supporting bars are suitably notched or cut to accommodate the aforesaid
arrangement of the fulcrumed ends of the bail shaped levers. Said levers, it is
obvious are instrumental in effecting the depressing of the different plungers,
respectively, and are operatively connected, by means of links M, within the type
writer's levers A 2 adapted to be operated by the typewriter's keys that are instru-
mental in printing numerals and each of said typewriter keys is operatively
connected with the bail shaped lever that is instrumental in the operation of the
computing machine's key that bears and is instrumental in registering the corre-
sponding number of the denomination recorded by the key row of which said last
mentioned key is a member. For instance, plunger markod 1 in Figs. II and III
is instrumental in effecting the depression of the key bearing the numeral 1 in the
different rows of keys of the adding machine, and the bail shaped lever that is
adapted to effect the depression of said plunger, is operatively connected, through
the medium of a link M, and a lever A 2, with the typewriter key Al that bears
numeral 1. Any suitable number of suitably applied springs O act to retain the bail
shaped levers in their elevated or normal position. A series of springs 0 are
provided, preferably at one side, or both sides, of the machine, and are suitably
attached at their lower ends, to the different levers, respectively, and are suitably
secured at their upper ends, to a rod or rods P extending between and secured to
legs A of the machine as shown in Fig. II.
Two rods and R (see Fig. 1) are rigidly secured to, and extend laterally of, the
central portion of the plunger carriage in opposite directions, respectively. Rod Q
at its outer end, is operatively connected with the longer arm of a vertically and
laterally tilting lever S that is fulcrumed, at $ 1, preferably a short distance from its
upper end to a stationary bracket a rigid with the stationary frame of the type
writer. Rod R is operatively connected at its outer end with the longer arm of a
vertically and laterally tilting lever T fulcrumed a short distance from its upper end,
at T1 to a bracket a 1 rigid with the stationary frame of the typewriter. Levers S
and T are fulcrumed in the same horizontal plane, and at their upper ends are
operatively connected with opposite ends, respectively of a horizontally arranged
rod U.
Rod U extends along the forward side and longitudinally of the suitably actuated
paper carriage A 4 of the typewriter, and is provided, at any suitable point between
its ends, with an upright arm U1 whose right hand side is adapted to be engaged
by the forwardly projecting dog or arm W I mounted upon the round rod or bar W
that extends longitudinally of the forward side and is a member of the aforesaid paper
carriage. Member W 1 is preferably adjustably secured upon rod or bar W by means
of a set screw W 2. Arm U 1 of rod U is preferably located about centrically between
the ends of the rod, and the aforesaid dog or arm of the paper carriage is located
preferably near the right hand end of the carriage so that the typewriter, during the
movement of said carriage between its point of starting at the right hand end of the
machine and the point at which its aforesaid dog or arm comes into engagement with
arm U1 of rod U, can be operated independently of the adding machine and hence
the operator can write upon the left hand side of his paper any remarks concerning the
items of the columns of figures to be placed upon the right hand side of this paper or
any other matter that he desires to have appear upon the paper in addition to the
numerical items, but as soon as the aforesaid paper carriage during the latter's
longitudinal movement, comes into engagement with the right hand side of the
upright arm of rod U, the latter will be shifted longitudinally to the left and actuate
lover S in the direction required to move plunger carriage G and the latter's plungers
to the right, and the arrangement of parts is preferably such that when said forwardly
projecting dog or arm of the paper carriage first comes into engagement with arm U 1

page_text: of rod U, the plunger carriage shall be in position (not shown) over the first row of
keys at the left hand side of the keyboard of the adding machine, and shall thence
be moved to the right from one row of keys D1 to the next row of keys D1
simultaneously with the leftward movement of the type writer carriage. When the
type writer's paper carriage, during its operation has arrived in its extreme left hand
position, and is thereon moved to the right into its starting position, rod U is also
actuated longitudinally to the right, by hand or in any approved manner, and thereby
actuates lever T in the direction required to move the plunger carriage to its
starting position at the left hand end of the key board of the adding machine.
It will be observed that the forwardly projecting dog or arm of the type writer
carriage can be oscillated rearwardly out of line with arm U 1 of rod U, as shown in
dotted lines, Fig. II and the plunger carriage actuated into a position over the space
had at the left hand side of the keyboard of the adding machine, shown in dotted
lines, Fig. I when it is desired to operate the typewriter independently of the adding
machine.
The recesses in the upper ends of the heads of the stems of the plungers
accommodate the movement of the plunger carriage without interfering with the
operative connection between said plungers and the bail shaped levers engaging said
recesses.
This improved machine will be found especially useful in banks, clearing houses,
and wherever addition or computation and typewriting are to be done upon the same
piece of paper.
