COMPLETE SPECIFICATION.
Tabulating Attachments for Typewriters.
I, LOUIS SCHLESINGER, of 145, La Salle Street, Chicago, County of Cook, State
of Illinois, United States of America, Manufacturer, do hereby declare the nature
of this invention and in what manner the same is to be performed to be particu-
larly described and ascertained in and by the following statement:-
The object of the invention is to provide a spacing attachment for typewriting

may be easily and expeditiously effected.

In the drawings and specification is shown, described and claimed, a spacing
attachment particularly adapted to securing speed and accuracy in tabulating
columns of words or figures, where, for instance, it is important that all units
in a column of figures shall fall under each other in a vertical line, and similarly
with tens, hundreds, thousands, tenths, hundredths, thousandths, or other
denominations, the attachment being so arranged as to be capable of adaptation
to recording numbers of any desired or varying denomination. The present inven-
tion relates to an apparatus or arrangement for securing these results efficiently
and expeditiously.
Referring to the accompanying drawings, the same part is designated by the
same reference sign. wherever it occurs throughout the several views.
A, designates the frame of a typewriting machine; B, the paper feed carriage;
C, the platen, or paper feed roll. These several parts may be of the usual or any
suitable, convenient or well known type of construction and arrangement, and form
no part of the present invention, except in their co-operative relation to the spacing
attachment.
Suitably bolted, or otherwise secured, to the framework of the typewriting
machine, at the rear end thereof, is a framework 17, in which are mounted a series
of movable plungers 18.
In Figs. 13 & 14 is illustrated a form of sliding plunger embodying the principles
of my invention, wherein each plunger is shown in the form of a plate having an
elongated slot or opening 19, therein, the slots or openings of the several plates
or plungers registering with each other when said plungers are assembled. It
is to be understood, however, that my invention is not limited or restricted to
sliding plungers, nor to the specific construction and arrangement thereof as shown!
in these views of the drawing. In the particular form shown, pins, bars, or other
suitable projections 20, 21, mounted in or formed on the side bars of the frame 17,
are arranged to pass through the registering slots or openings 19, of the assembled
plates. The elongated slots or openings 19, are somewhat longer, according to the
degree of projection which is to be imparted to the plungers, than the distance
between the pins or projections 20, 21, the said pins or projections thus forming
supports for the plungers and guiding the same during the movements thereof,
and also forming stops therefor when said plungers reach the limits of their move-
ments, thus securing uniformity in degree of movement of all the plungers. If
desired, and in order to secure easy working of the parts, the pins or projec-
tions 20, 21, may be provided with sleeves 22, which are of just sufficient external
diameter to pass snugly through the longitudinal slots or openings 19, of the
plungers without causing said plungers to bind thereon. Thus the sleeves consti-
tute the contacting surface with the walls of the slots or openings, and hence permit
the plungers to move freely and accurately thereen when suitably projected. These
sleeves also serve to suitably space the side bars of frame 17, thus preventing said
side bars from being drawn so close together as to cause the plungers 18, to bind
against each other. It is obvious, however, that this specific construction and
arrangement of the parts may be altered and changed, or the sleeves omitted,
or the shape thereof varied, and still not depart from the spirit and scope of my
invention, the essential feature being the provision of movable plungers, whatever
the specific construction and arrangement thereof.
Suitably mounted upon to travel with the paper feed carriage B, as will be more

page_text: particularly hereinafter explained, is a rack bar 23, adapted to carry suitable
stops 24, presently to be more fully described. The ends of the plungers 18,
when said plungers are in their normal or retracted position are held out of the
path of traverse of the stops 24, when the paper feed carriage proceeds upon its
movements during the ordinary operation of typewriting. The arrangement is
such, however, that when a plunger 18, is moved from its normal position, as shown,
for instance, in Figs. 1, 2, 3 & 8, it.intersects the path of traverse of stops 24,
and hence when the paper feed carriage reaches the point where a stop 24, engages
the projected end of the plunger the movement of said carriage will be arrested.
Many specifically different arrangements may be employed for moving the
plungers. For instance, and in the construction shown in the drawings as illus-
trative of the principles involved (see particularly Figs. 3, 6, 11, 12, 13, 15 & 16),
a series of levers 26, corresponding in number to the number of plates or plungers
employed, are provided. Each lever 26, is arranged to loosely engage one of said
plates or plungers 18, so that when said lever is actuated its corresponding plunger
is moved.
In Figs. 12 & 13 is shown a simple and convenient loose connection between
the levers 26, and plungers 18, as illustrative of the principles involved, but the
invention is not limited to this specific construction. As shown in said views of
the drawing, the end of each lever is provided with a notch arranged to straddle
or engage over a lug or projection 25, suitably formed on or secured to the
plungers 18, and in order that the levers 26, or projections 25, may offer no
obstruction to the movements of the plungers, said plungers may have suitable
seats or depressions 29, formed therein to receive the ends of the levers. In the
generic conception of the invention, however, the particular form of connection
between the levers and plungers is unimportant, the essential feature being that
the connection is such that when any particular lever is actuated it moves its
corresponding and co-operating plunger into position to form a stop for the paper
feed carriage.
In
In the form of the invention illustrated in Figs. 3, 6, & 11, the levers 26, are
pivotally mounted intermediate their ends, as at 27, and to the lower ends thereof
are suitably connected the operating bars 28, by which said levers are actuated.
The operating bars may be arranged in any suitable or convenient manner.
the form shown in Figs. 6 & 7, said bars are arranged to extend to the forward
side of the machine into convenient position to be manipulated by the operator,
and suitable auxiliary keys 29, are provided by which said bars 28, and through
them the levers 26, are actuated. Instead of the arrangement of levers 26, above
described, and as illustrative of the generic character of the invention, said levers
may be in the form of bell crank levers 30, pivotally mounted at the angles thereof,
as at 31, (see Fig. 8), and rods 37, are provided and suitably connected at the
respective ends thereof to the free arms of bell crank levers 30, and the operating
bars 32. These bars may be similar in their construction and arrangement to the
bars 2S, above described. and may in a similar manner extend to a suitable and
convenient place to be readily and easily manipulated by the operator. In the
form shown in Figs. 6 & 7, the bars 28, are arranged to be projected endwise when
the auxiliary keys 29, are manipulated, and springs 33, may be provided and
suitably arranged to oppose the endwise projection of said bars, whereby said bars,
and consequently the levers 20, and plungers 18, are normally held in retracted
position. In the form shown in Figs. 8 & 10, the bars 32, are arranged to be
rocked, and to this end said bars are provided with the crank arms 34, to which
the auxiliary keys 35, are connected, while the rotary or rocking movement of
said bars 32, may be opposed by suitably arranged springs 36, operating in a
similar manner to springs 33, to hold bars 32, and rods 37, and hence also the
plungers, in normal retracted position. By the construction illustrated in Figs. 8
& 10, I am enabled to place the auxiliary keys 35, vertically, similarly to the
usual arrangement of the ordinary keys D, in a typewriter, whereas in the con-
struction shown in Figs. 6 & 7, the auxiliary keys are arranged to operate in a plane

page_text: at right angles to the plane in which the ordinary keys D, operate. The particular
arrangement of the means for operating the plungers 18, however, is unimportant,
so far as the generic conception of my invention is concerned, the essential feature
being that said means are so placed as to be readily and easily manipulated by the
operator.
As above stated the stop rack 23, is suitably connected to move with the paper
feed carriage B. This connection may be arranged in many specifically different
ways, the essential feature being that said rack bears a definite relation to the
ordinary spacing scale of the machine and to the teeth of the carriage feed rack
bar, and that it is capable of a desirable range of adjustment. In the form shown
in Figs. 1, 4, & 5, the rack bar 23, is supported at each end by the plates 38,
and screws 39, said screws passing through elongated slots 40, in said plates, (see
Fig. 5), whereby, by loosening said screws, a desirable range of longitudinal
adjustment of said rack may be secured. The plates 38, are supported by means
of a bracket or 'bar 41, suitably mounted on or connected to move with the paper
feed carriage. The arms of bracket 41, are slotted as at 42, Fig. 4, whereby by
loosening screws 43, the rack 23, may be adjusted laterally, as will be readily under-
stood. This lateral adjustment of the rack is desirable, particularly in that style of
typewriter where the plunger casing is rigidly connected to the machine frame.
Where it is possible, the same ends may be attained by adjusting the plunger casing
towards and from the rack, as shown in Fig. 2.
Instead of the construction above described for securing the rack 23, to the
paper feed carriage, and as illustrative of the generic character of the invention,
I may support said rack by means of brackets 44, at each end, according to the
particular type of machine to which the tabulating attachment is to be applied,
and said brackets may be suitably connected to the paper feed carriage in a suitable
manner to secure the desired range of adjustment of the rack.
The rack 2, is provided with a series of teeth or notches 45, preferably, though
not necessarily, corresponding in number to the divisions of the ordinary spacing
scale, and fo the rack teeth on the paper feed carriage rack. In practice I prefer
to arrange the notches or teeth 45, a distance apart corresponding to the distance
traversed by the paper feed carriage in moving one letter space, and for the sake
of expedition and convenience, said rack may be suitably marked or graduated
to correspond with the graduations of the ordinary spacing scale.
In the particular form shown, to which, however, the invention is not limited
or restricted, the rack 23, is provided with notches or teeth on both sides thereof,
as shown, though the invention is not limited to the particular shape of the rack
bar nor to the particular size and arrangement of slots or grooves therein, and
the stops 24, may comprise flat plates of a thickness adapting them to be received
in said teeth or notches. Said stops are slotted or grooved in the edge thereof,
as shown in Fig. 18, the width of said slot or groove corresponding to the thickness
of the solid portion of said rack 23. By this construction it will be seen that the
stops may be readily and easily straddled over the rack, and the side walls of the slot
or groove in said stops will be received in the teeth or slots in the rack, thus
efficiently, firmly and detachably holding the stops in position to arrest the paper
feed carriage at the desired point when the tabulator attachment is suitably
actuated.
In the operation of a tabulator attachment embodying the principles of my in-
vention, it is important to release the paper feed carriage from its feed mechanism
when a plunger 18, is moved into position to form a stop so that the main feed
carriage operating spring will quickly and expeditiously move the carriage until
the movement thereof is arrested by the plunger. This release of the paper feed
carriage from its feed mechanism may be effected in many different ways, and either
independently of, or, and preferably, automatically with the actuation of the
plungers, the important feature being that the paper feed carriage is released
from its feed mechanism. The particular means employed for accomplishing this
result may vary with the different styles and types of machines to which the

page_text: tabulator attachment is applied, and with the different styles and types of paper
carriage feed mechanism. In the drawings I have shown a construction as illus-
trative of the principles involved, wherein the release of the paper feed carriage
from its feed mechanism is effected automatically by the actuation of a plunger.
The invention, however, is not limited or restricted in this respect. In the form
shown a bar or arm 46, is arranged in position to be engaged and moved coinci-
dently with the movement of any one of the plungers. As shown in Figs, 3, 6, 8,
16 & 17, this movable bar or arm may be in the form of a strap or bail suitably
arranged in position to be engaged and moved when any one of the plungers is
moved. A convenient arrangement is shown wherein each plunger is provided
with a lug or shoulder 47, and the arm or movable part 46, is arranged in position
to be engaged by said lugs. In the bail or strap form of construction the arms or legs
of the bail or strap may be suitably pivoted, whereby when any one of the plungers
is moved the lug or shoulder 47, thereon engages the arm or bar 46, and rocks the
same. By arranging the arm or bar 46, transversely across the several plungers
and in front of the shoulders or projections 47, it will be seen that when any one
of the plungers is moved the said arm or bar 46, is also moved. If desired, and as
shown in Fig. 15, the arm or bar 46, may be arranged across the front ends of the
plungers so as to be moved when any one of the plungers is projected. In this
arrangement of course the projections or r shoulders 47, may be omitted. It is
obvious that many other specifically different arrangements may be employed
to secure the movement of the bar or arm 46, when any one of the plungers is
moved, and still fall within the spirit and scope of the invention. A spring 48,
may be employed and arranged to normally maintain the arm or bar 46, in retracted
position and to oppose the movement of said arm or bar when moved by the pro-
jection or movement of a plunger. This spring also aids in returning the plunger
to its normal or retracted position. In the particular form shown, wherein the
paper carriage feed mechanism is automatically released by the actuation of a
plunger, suitable connection is made between the movable arm or bar 46, and the
feed mechanism of the paper carriage, whereby when a plunger is actuated, thereby
effecting a movement of the arm or bar 46, the said feed mechanism is released.
The character of this connection, it is evident, varies according to the style and
type of the machine, and the construction and arrangement of the carriage feed
mechanism. In the form of machine shown in Figs. 2, 8 & 9, the paper carriage
is fed in the ordinary operation of typewriting by means of a feed rack E, carried
in a frame F, pivotally mounted as at G. The rack is fed by a pinion H, on a
shaft carrying the escapement ratchet J, (see Fig. 2), and may be actuated in the
usual and well known manner of machines of this style, by the operation of the
ordinary type bars. A rock shaft 49, is suitably journaled in bearings on
the machine frame and at one end thereof said shaft is connected in a suitable
and convenient manner to arm or bar 46, or the bail or strap connected therewith,
as by means of the crank arm and connection 50. By this construction it will be
seen that when the arm or bar 46, is moved, that is, when a plunger 18, is moved,
thereby rocking or moving the bail or strap, said shaft 49, is rocked in its bear-
ings. At the other end of said shaft, means are provided and arranged to engage
the feed rack E, of the paper carriage, and raise the same out of engagement with
the feed pinion H. In the particular form shown, to which, however, the invention
is not limited or restricted, a crank arm 51, on the front end of said shaft 49,
carries a block or roller 52, which when said shaft is rocked engages and raises
the rack E, out of mesh with pinion H, thus releasing the paper carriage from
its feed mechanism and permitting the main operating spring to cause the carriage
to move quickly across the frame of the machine until the movement thereof is
arrested by a stop 24, coming into contact with the projected plunger. In this
arrangement the weight of rack frame F, aids spring 48, in returning the parts to
heir normal or initial position.
In Figs. 1 & 3 is shown the application of a tabulator attachment to a machine
wherein the escapement pawl·K, of the carriage feed mechanism is pivotally

page_text: mounted, and is connected by means of a rod 53, to the movable arm or bar 46,
whereby when said arm or bar is moved, as above explained, the rack pawl K,
is swung out of engagement with carriage feed rack L, thus disengaging the
carriage from its feeding mechanism.
In Figs. 16 & 17 is shown the tabulator attachment applied to another style of
machine, wherein the carriage feed rack P, is disengaged from its operating
pinion Q, by means of a bell crank lever 60, having one of its arms suitably con-
nected as by means of a rod 61, with the movable bar or arm 46, whereby when
any one of the plungers is moved said bell crank lever 60, is rocked. The other
arm of bell crank lever 60, is arranged over a bar 62, which is connected to the
paper feed carriage in position, when depressed, to cause the pinion Q, to be dis-
engaged from the rack P.
In some styles of machines it sometimes happens that when the tabulator
attachment is operated the momentum of the paper carriage, when released from
its feed mechanism, causes said carriage to move beyond the point where it is to be
arrested. This fault is liable to occur in that style of machine where no special
arrangement is employed to limit or check the ordinary escapement ratchet when
the disengagement of the carriage feed mechanism is effected by the operation
of the tabulator attachment. In order to avoid this trouble, means may be pro-
vided for locking the paper carriage feed mechanism against movement when the
tabulator attachment is actuated. This idea may be carried out in many specifically
different ways, and still fall within the spirit and scope of the invention. As
illustrative of an operative arrangement embodying the principles of my invention,
I have shown in Figs. 16 & 17 a construction wherein is employed an arm 63,
connected to move with the rod 61, by which the carriage feed mechanism is
released. This arm 63, is arranged when moved to enter the space between ad-
jacent teeth of escapement ratchet wheel R, by which pinion Q, is actuated. In
this manner, it will be seen that when a plunger of the tabulator attachment is
moved into position to arrest the carriage and the carriage feed mechanism is
released and thrown out of action, said feed mechanism is locked against further
movement and hence is brought to a state of rest, so that when the auxiliary key
through which the plunger is moved is released and the parts return to their normal
or initial positions, and engagement of the carriage feed mechanism is again estab-
lished, no danger is incurred of the carriage being carried further by such feed
mechanism until further manipulation takes place.
It sometimes occurs that the plungers will stick or bind together so that when
one is moved the next adjacent one will also be carried along with it, thus
deranging the spacing and tabulating functions. In order to avoid this trouble,
I provide grooves in the sides of the plungers, arranged to extend in the direction
of movement thereof, as indicated at 70, Figs. 13 & 14. By the provision of these
scores or grooves the danger of adjacent plates binding or sticking together is
reduced.
con-
When the paper carriage is released from its feed mechanism by the operation
of the tabulating attachment, the main carriage operating spring causes
the carriage to move with considerable speed and force until it
tacts with the projected stop or plunger. This imparts an undesirable shock or jar
to the machine and its parts. In order to overcome this, I have provided a brake,
arranged to impede, to some extent, the movement of the paper carriage when
released from its feeding mechanism. In the particular arrangement of brake
shown, to which, however, the invention is not limited, a brake arm 71, is pivotally
mounted upon a suitable part of the frame, as, for instance, a side bar of the
frame 17, and at its free end carries an adjustable brake shoe 72, of rubber, leather,
or the like, which is arranged to be moved into contact with the surface of a mov-
able part of the paper carriage, as, for instance, in the particular form shown, the
stop rack 23. If desired or necessary, the stop rack may be suitably grooved in
the surface thereof with which the shoe 72, contacts, and a lining of leather or
other suitable material may be arranged therein. The brake lever or arm 71,

page_text: may be suitably and conveniently actuated coincidently with the actuation of any
one of the plungers, by providing a pin 74, in the strap or bail which carries arm
or bar 46, and arranging such pin to engage a cam surface 75, of said lever 71.
From this construction, illustrative of the principles of the invention, it will be
seen that whenever a plunger of the tabulating attachment is actuated, a brake is
automatically applied to the paper carriage, thus relieving and reducing the shock
and jar of impact of said carriage against a stop, and by adjustably mounting
the brake shoe, provision is made for regulating the amount of braking effort.
It will also be seen from the construction above described that the brake is not
applied until the carriage is released from its feeding mechanism.
From the foregoing description it will be seen that any number of columns may
be written, and that they may be as close together or as far apart as may be
desired. By employing a rack bar 23, having grooves or notches therein, and a
stop plate 24, which is grooved to straddle the bar and to enter the notches or
grooves in the rack bar, it will be seen that the stops are absolutely held against
displacement by the shock of the carriage when released from its feed mechanism,
and by providing grooves on both sides of the rack the stops are efficiently braced
to receive the shock of the carriage. By providing grooves or notches in the rack
corresponding in number and distance apart to the spacing scale, and to the
distance the carriage moves in traveling a letter space, it will be seen that the stops
may be quickly arranged at any desired point and as close together, if desired, as
the distance of a letter space. It will also be seen that the adjustment of the stops
is not dependent upon the accuracy and skill of the operator, but when a stop
is once placed in the desired position on the rack bar, that position corresponds
absolutely to the spacing scale position thereof which is previously determined
upon, provided the stop rack has been suitably adjusted to the spacing scale and
the carriage feed rack."
It will be observed that the front ends of the plungers are beveled as at 65. The
object of this arrangement is to enable the plungers to readily and easily enter
the space between stons 24, even when said stops are arranged to occupy adjacent
notches or grooves in the rack 23.
The operation of a tabulator embodying the principles of my invention is as
follows: Suppose it is desired to write a column of figures of various denomina-
tions, for instance, with all the units falling under the "10" mark of the spacing
scale, and another column with the units falling under the "20" mark of the
spacing scale, and so on with as many columns as may be desired, the operator
places a stop plate 24, in the notch or groove of the rack bar 23, which corresponds
to spacing scale mark "10," another in the notch or groove corresponding to
spacing scale mark "20," and so on. Now suppose the first number of the first
column is a number of units denomination, the first number of the second column is
of tens denomination, and so on, the operator, after placing the paper
carriage in its extreme or initial writing position, first operates the
"units" key of the auxiliary series, 29, that is, the one marked "1"
in Fig. 7, the corresponding plunger is accordingly advanced, the paper
carriage is released from its feed mechanism, and the carriage moves
freely under the influence of the main operating spring, retarded if desired by
the brake shoe 72, until the first stop plate 24, abuts against the projected plunger.
This arrest of the carriage occurs in the position necessary to record the unit of
the first number of the first column. When this record has been made the operator
operates the "tens" key of the auxiliary series, thus advancing its corresponding
plunger. At the same time the paper carriage is again released from its feed
mechanism and is arrested in position to record the first digit of the number. Thus
the operator continues the operation for the first numbers of all the columns to
be tabulated. The operator then causes the paper to be advanced for the next
line, and at the same time returns the carriage to its initial position. The opera-
tions above described are then repeated for the second numbers of each column,
the denomination of the number to be recorded determining the particular auxiliary

page_text: key to be operated, and when any one of the auxiliary keys is operated the carriage
is arrested at the desired point for recording the first digit of the number to be
recorded, and all the numbers in each column are recorded with the units under
units, tens under tens, and so on throughout any desired denomination.
Having now set forth the object and nature of my invention, and various forms
of apparatus embodying the principles thereof, and having set forth and described
the construction, function and mode of operation thereof, I desire it to be under-
stood that my invention is not limited or restricted to the exact details of con-
