This invention relates to a new and useful improvement in calculating machines,
the object being to construct a machine of the character described which will
add and multiply numbers.
The novel features of this invention are:
First: The arrangement and peculiar construction of the key bars with their
actuated racks, in combination with the adding mechanism, whereby the racks
are first placed in position before they engage the adding mechanism, thus
insuring a proper and positive movement of the adding mechanism from the
racks when the operating lever is actuated.
Second: The novel construction of the operating lever in combination with the
racks, the key board and the adding mechanism, whereby, when the racks are in
position, said lever will throw the adding mechanism into engagement with the
racks and move the racks so as to actuate the adding mechanism while said
adding mechanism is in engagement, said lever only releasing the adding mechan.
ism and permitting its disengagement from the racks, after the racks have com-
pleted their movement.
Third: In the peculiar construction and arrangement of the adding mechanism
in combination with a transferring device for transferring the amount added to
one adding wheel, when sa. amount exceeds nine, to the next adding wheel.
Fourth In the peculiar construction and arrangement of the adding mechan-
ism, and the use of a cam snail wheel in connection with said adding
mechanism, in combination with the printing segments, whereby, when desired,
a total of the amount contained in the adding mechanism can be obtained at any
time without disturbing the adding wheels.
Fifth: In the peculiar construction of the printing segments, in combination
with a pivoted zero type-carrying device which is automatically thrown into
position on all the segments to the right of the one actuated.
Sixth In the novel arrangement of these pivoted printing characters on the
swinging printing segments, whereby, when any of said segments is operated and
said pivoted printing characters to the right of said operated segments are in
position, they will not interfere with the operation of the segments to which they
are pivoted.
Seventh In the novel construction and arrangement of the printing hammer
and its operating mechanism.
Eighth In the peculiar construction of the supporting frame for this printing
hammer and the paper feed, whereby, the paper to be printed upon, such as the
leaf of a book, may be introduced from the side. And, finally, the invention con-
sists in the construction, arrangement and combination of the several parts of my
device, all as will be hereinafter described, and afterwards pointed out in the
claims.
In the drawings, 1 indicates a suitable frame in which the operating mechan-
ism is mounted. This frame is braced by suitable cross-bars and through-bolts,

page_text: and preferably encased by a suitable shell, but as the frame and shell may be
changed in different ways and still answer the purposes for, which they are
designed, I will not give a detailed description here of these parts.
2 and 3 indicate two shafts arranged in the front part of the machine upon
which the key bars 4 are pivoted. The arrangement of these key bars is more
clearly shown in Figures 3 and 19, where, it will be seen that the key bars for
a series of keys, that is, in speaking of a series of keys I means those keys which
bear the numerals from 1 to 9, inclusive, are nested, the nest being preferably
divided into two divisions, five of which key bars of a nest are pivoted on one
of said shafts, as 2, while the remaining four of the nest are pivoted on the shaft 3.
Each key bar has connected to it an ear 5 which receives the shank 6 of a key 7,
said key being held in its normal position by a spring 8.
The
Formed on, or attached to, the key bars 4, are fingers 9 which, with the key
bars, form recesses of varying depths, according to the position of the key bar in
the nest of keys and the number on the key attached to that particular key bar.
In other words, a recess in the key bar to which key "1" is attached, is but one-
ninth as deep as the recess of the key bar to which key "9" is attached.
intermediate keys have their recesses graduated between the shallowest and the
deepest, as shown in Figure 18 (Sheet 13), wherein the key bar shown at the top
of the figure is for key "9," while the key bar shown at the bottom of the figure
is for key "1."
10 indicates sliding bars which I will call rack bars, because the racks which
engage the adding mechanism, are attached to these bars. These bars are
slidingly mounted in the frame of the machine beneath the key bars, and
springs 11, attached to said rack bars and to the framing, tend to force said rack
bars forwardly at all times, upon their release.
19 (Fig. 4) indicates yielding trips which are arranged in front of
the rack bars to hold said rack bars in their normal rear position.
These trips are provided with cross-bars 13 at their upper ends which
are
the key bars, whereby, when said key bars
engage
depressed, the
trips are also depressed. The cross-bars 13 are so arranged that one
cross-bar includes one nest of key bars, whereby, upon the operation of any one
of the keys in a nest, said key bar will actuate this trip and release the rack bar
controlled by the trip. In the drawings, there are shown nine series of keys with
which co-operates nine rips, said trips each controlling a rack bar, of which there
are also nine. It will be understood in this connection that, while I have shown
nine series of keys and nine rack bars, the capacity of the machine could be in-
creased or diminished without departing from the nature and principle of my
invention.
Each rack bar is provided with a cross-bar 14 adapted to co-operate with the
recesses in the key bars forming the nests, that is, these cross-bars 14 are of such
dimensions as to include in their path of movement an entire nest of key bars,
as shown in Figure 8. In this respect they correspond with the cross-bars 13 of
the trips 12.
Upon the actuation of any key in a series, said key will depress its attached
key bar, which, bearing upon the cross-bar 13 of the trip 12, will force said trip
out of the path of its rack bar. The rack bar being released, its spring 11 will
bring it forward until the cross-bar 14 is seated in the recess of the depressed key
bar. By the presence of fingers 9, it is impossible to operate any key in a series
after one of the keys in that series has been operated.
In Figure 4 this construction is clearly illustrated where, it will be seen, that
key "5" has been depressed, releasing the rack bar, and that the rack bar has
moved forward until its cross-bar 14 has become seated in the recess and its
motion arrested. The finger 9 of the key bar will be under the cross-bar 14 when
the key is depressed, and the rack bar moves forward and will hold said depressed
key down until the rack bar has been returned to its normal position.
enables the operator to determine, at any time, before the operating lever is
This

page_text: operated, what keys have been depressed, and, if a mistake has been made, the
lever may be pulled forward, as will hereinafter be described, and all the key bars
released and the rack bars restored to their normal position without affecting the
adding mechanism.
15 (Figs. 1, 4, 5, 6) indicates racks on the rack bars, which racks are adapted
to engage wheels in the adding mechanism. These wheels may be in the form of
pinions, but I have shown them as hair-lantern wheels 16, which wheels are
conjoined to numbered discs 17 loosely mounted on a shaft 18, jourualled in a
frame 19, which is pivoted to the framing 1, at 20. 21 indicates a detaining
pawl which engages the teeth of wheel 16 and serves to center the teeth thereof
relative to its respective rack.
22 (Figs. 3 and 5); indicates the operating lever pivoted on each side of the frame
of the machine at 23, thereby extending entirely across the breast of the machine,
so that it can be operated by grasping it at any point over the machine. The lower
end of this operating lever has mounted upon it, a pivoted dog 24, (Fig. 4) which
is adapted to engage and depress a cam lever 25, pivoted at 26 to the framing
of the machine. This lever 25 and dog 24 are so arranged relative to each other
that, when the operating lever is pulled forward, the dog 24 will straighten out
as shown in Figure 2 and depress the lever 25. A rod or wire 27 connected to
the dog, and to a pivoted handle 28 on the upper end of the lever, is adapted to
throw the dog 24 out of operative relation to the lever 25, in order to permit the
handle 22 to be pulled forward without operating lever 25, as, when a mistake
has been made in depressing the wrong keys on the keyboard, or it is desired to
return the adding mechanism to zero, as will hereinafter be explained.
Connected to the end of lever 25 is a link 29, whose other end is connected
to the swinging frame in which the shaft 18 of the adding mechanism is
mounted.
From the above it will be seen that, by depressing a key on the keyboard, which
will release a rack bar, said rack bar will move forward until it is arrested, at
which time a number of teeth on rack 15 will have passed a point on wheel 16
equal to the number on the key which was depressed. A movement of the lever 22
in a forward direction will rock lever 25 and depress the frame of the adding
mechanism until the tooth at the lowest point of wheel 16 will engage the
rack bar.
Upon the forward movement of lever 22, an arm 30 fixed thereto, as shown in
Figures 1, 5, 6 and 7, will, after the dog 24 has engaged the lever 25 and depressed
the frame of the adding mechanism, engage a lever 31 pivoted to said arm 30.
This engagement is preferably accomplished by means of a lateral projection 32
on the arm 30, which engages the arm 31 after an initial movement has been
imparted to the lever 22, during which initial movement, the adding mechanism
was thrown into engagement with the racks. When the projection 32 engages
the lever 31, then said lever 31 becomes part of lever 22 and by reason of a linked
connection 33 with a cross-bar 34, will, through the medium of said cross-bar
engaging a projection 14" on the rack bar, or bars, which have been actuated,
return said rack bars to their normal position. This projection 14 on the rack
bar preferably has the cross-bar 14 mounted in its upper end as shown. This
return of the rack bars is accomplished during the final movement of lever 22
and, as the rack bars are in engagement with the wheels 16, said wheels 16 will
be rotated a distance corresponding to the movement of the rack bars.
Figure 5, it will be seen that a rack bar has been moved forward the distance of
five teeth, which means that a "5" key has been depressed. In this figure the
lever 22 has not yet been operated. When, however, the lever 22 is operated, it
first depresses the frame of the adding mechanism so that the teeth of wheel 16
engage the rack bar. By this time, as shown in Figure 6, the projection 32 will
have engaged the lever 31, and a further movement of lever 22 will, through the
movement of cross-bar 34, return the rack and rotate the wheel. These racks in
their normal position are so located relative to the wheels 16 that, whenever said
$
In

page_text: adding mechanism frame is depressed, one of the teeth of wheels 16, the lowest,
will engage with the orward recess of the racks. By this construction, when the
racks are in engagement with the wheels and are returned to their normal
position, the wheels abe never released until the racks have completed their
movement. Thus, it will be seen that no momentum is imparted to the wheels 16,
but, to the contrary, said wheels are brought to a dead stop and then released.
Whenever, by the repeated actuation of any of the wheels 16, said wheels have
been made to travel nine-tenths of a complete revolution, it is necessary to transfer
the amount added on said wheels to the next higher wheel. I will now describe
the manner in which this is accomplished. Each of the indicating wheels 17,
which are conjoined to wheels 16, and preferably form part thereof, is provided
with a projection or tooth 35 (Fig. 6). 36 indicates what I shall term a hook
bar, which is pivoted to a rock arm 37, said arm being mounted upon a shaft 38.
The forward end of hook bar 36 is formed like a hook which normally engages a
bar 39 rigidly fixed to the framing of the machine. When the hook is thus in
engagement with the bar 39, it is in the path of the tooth or projection 35 on
wheel 17, and when said wheel has made nine-tenths of a revolution, the projec-
tion is in such position that it has engaged and released the hook bar from the
bar 39, in which event a spring 40 attached to rock arm 37 will cause said hook
bar to be retracted until a projection 41, carried thereby, has engaged the rock
arm 37, as shown in Figure 6, which projection arrests the rearward movement
of the hook bar, and at the same time places a projection 42, depending from the
rear end of said hook bar, in the path of a travelling transfer mechanism which
is operated as follows:
When the bar 34 moves to the rear to carry with it the rack bars, it also
engages a projection 44° in its path, said projection 44ª extending upwardly from
a link 44 which is connected to one member 45 of a bell crank lever, of which the
member 46 forms the other part. This bell crank lever is pivoted beneath a cross-
bar of the frame of the machine, located at the front end of the machine, and a
spring 46 connected to the member 46 tends to hold said member to one side of
the machine which, we will say, is the left hand side of the machine. As before
stated the engagement of bar 34 with the projection 44 will move said bell crank
lever from the left hand side of the machine, to the right hand side of the machine.
The rear end of meniber 46 has extending upwardly, a projection 47, which
engages a stud 48, said stud extending from a frame 49 slidingly mounted on a
shaft 50 secured to the framing of the machine. This frame 49 extends forwardly
and embraces a grooved shaft 51 mounted in a swinging frame 51ª, said frame 49
confining between its members, a pinion 52, which is provided with a key running
in the groove of shaft 51. This shaft is adapted to be rotated, and rotate with it,
the pinion 52.
The means for causing the rotation of shaft 51 is illustrated in Figures 2 and 7,
where it will be seen that an arm 53 is fixed to lever 22. A pivoted segment 54
is oscillated from said arm 53 by a link 55, said segment being held normally in
a forward position by a spring 56. Segment 54 meshes with a pinion 57, to
which pinion is conjoined a ratchet wheel 58 as shown more clearly in Figure 23.
59 indicates a fly-wheel carrying a pawl 60 which co-operates with the ratchet 58.
Conjoined to this fly-wheel is a pinion 61 meshing with a pinion 62 mounted on
the end of the shaft 51 upon which the pinion 52 is mounted. By reference to
Figures 2 and 7 it will be seen that, when the operating lever 22 is moved from
the position shown in Figure 7, to the position shown in Figure 2, it will, through
the medium of arm 53 and link 55, oscillate segment 54 and store up power in
spring 56. Immediately that lever 22 is released, spring 56 tends to return it
to its normal position, and by reason of the ratchet and pawl connection with the
fly-wheel, also rotate said fly-wheel positively until the segment completes
its forward movement, when said fly-wheel will continue to rotate
by reason of its momentum. This actuation of lever 22 will, as we
have seen, move the arm 46 of the bell crank lever to the right

page_text: hand side of the machine, and as soon as said lever is released the spring 46"
will act to return the bell crank lever to its normal position at the left hand side
of the machine, and the pinion 52 will also be rotated. If, as before described,
any of the hook bars have been thrown out of engagement with the bars 39 by the
pins 35 on the indicator wheels 17, said hook bars will have been moved so that
their depending projections 42 are thrown in the path of the frame 49, or a pro-
jection 43 extending upwardly from said frame. The two projections just
described, contacting with each other as shown in Figure 6, will arrest the
frame 49 in its movement, and the rotating pinion will engage a tooth or pre-
jection on the lower end of rock arm 38, and force said rock arm forward, as shown
in Figure 21, restoring the hook bar to its engaged position relative to the bar 39,
and also moving forward a push bar 63 whose end will engage the teeth of the
next wheel 16, and move said next wheel 16 the distance of one tooth. This push
bar 63 is pivoted to the hook bar as shown in Figures 5 and 6, so that upon the
completion of its movement, or when restored to its normal position, it will permit
the travel of wheel 16 without interruption, said push bar riding over the teeth of
the wheel.
By moving the frame 49 and pinion 52 to the right of the machine, said pinion
will engage the rock arms of the units wheel first, and if by a transfer from the
units wheel, the tens wheel releases its bar, the frame 49 will be arrested at the
tens rock arm 38 and carry from the tens wheel to the hundreds wheel, and so
along the entire line.
Secured to the rack bars is a link 64, whose other end engages an arm depending
from the printing segments 65, said printing segments being pivotally mounted
on a shaft 66 arranged across the rear end of the machine. These printing
segments, as shown more clearly in Figure 10, are nested together, that is, there
is no space except that necessary for the easy operation of each segment, between
the segments. All of the segments extend straight down and are mounted directly
upon the shaft 66. As the rack bars to which the separate or individual segments
are connected, are distributed practically over the entire width of the machine,
it is necessary that a straight and positive connection be made from the rack bars
to the segments. Referring to Figure 10, the outer segments extend down and
are directly mounted upon the shaft 66, while a cross piece 67 extends laterally
and is mounted upon the shaft 66 near the ends of said shaft, said piece 67 being
then extended downwardly and connected to the links 64. The segments next
to the outer segments are connected to their respective rack bars by means of a
vertical portion 68 mounted upon the shaft 66 to the inside of the vertical portion
of the outer segments, said vertical portion 68 being then bent inwardly and
horizontally under the portion 67, and downwardly, affording a bearing on
shaft 66, and under the outer segments to the segments next to the outer regments.
The next or third segments from the outside, are also extended down and have
a dírect bearing upon shaft 66. A cross-bar 69 connects the lower ends of these
segments to vertical portions 70 mounted on the shaft CG within the line of the
vertical portions 68. The next or fourth segments from the outside extend down
vertically and have a direct bearing on shaft 66 while the portions of said segments
to which the links 64 are connected, are formed with a jog or bend 71 to avoid the
horizontal portion 69. The fifth segment from the end, being the middle segment
of the nest, extends straight down and has but one bearing on the shaft 66.
It is obvious from the above description that any movement of the rack bar
will move the respective segment a corresponding distance, and it is desirable
that this relation between the segment and rack bar be maintained, because the
segment is then balanced.
In order to print a zero mark, or naught, to the right of any number presented
to the hammer by any segment, I pivotally mount on said segments a zero-carrying
frame, which frame normally rests upon a bar 73, Fig. 6, when said frame is
not in printing position, as shown to the right in Fig. 27 (Sheet 14). In order
to clearly describe the construction and operation of these zero printing frames, I

page_text: will refer to that part which carries the type, as 74, and to that part which rests
on the bar 73, as 75. I will assume that the middle segment has been operated so
as to present type "5 under the printing hammer (see Figs. 26 and 27), and 1
its movement to the rear to accomplish this, the arm 75 has passed beyond rod 73,
and its end, acting as a cam face, has raised said arm until its outer face has
contacted with a projection 76 on the arm 75 to the right. This will cause the
elevation of said next arm, and, as this last mentioned arm is also beneath a pin
on the next adjacent arm to the right (which would be to the left in Figure 27),
it will raise said next adjacent arm, the operation being carried out on all of the
arms 75 which are to the right of the one actuated, which passed beyond the bar 73,
as shown in Figure 6. These arms 75 are each curved on their outer faces, said
curve being described from such a center as will be common to the axis of the
shaft 66 when said arms are raised as shown in Figure 6. By so curving the outer
faces of arms 75, it is possible to operate any segment to the right of one previously
operated, without disturbing the relation of any of the pins and arms as above
described. The elevation of the arms 75 causes the portion 74 to align itself so
tha: its printing character "zero" will be in line with the number to be printed.
In this connection it might be well to say that the movement of the portion 74
is limited by contacting with the rear end of the printing segment on which it
is pivoted.
The normal position of these printing segments 65, and the pivoted naught-
carrying arm 74, is such that a space is left between them and any operation of
the lever which would not operate any of the printing segments, but would cause
the type hammer to deliver a blow, such blow would be struck between the seg-
ments and their pivoted naught-carrying arms, or, into space. This construction
permits the paper to be spaced without printing characters upon it at every
operation of the lever, and is useful in dividing columns of figures where it is

obvious by examining the Figure 27, wherein, to the right of said figure, it will be
seen that the naught-carrying arms are some distance away from the printing
segments, and when the hammer is forced down on the aligned type to the left,
it will strike said aligned type; but the three segments, to the right, and
onl each side of the
the naught-carrying arms, being separated, and
printing hammer, said hammer will strike between them, thus saving
it from unnecessary wear. It will be understood that when no type are in
position, and the handle is operated, all the naught-carrying arms will be in the
corresponding position to the three shown to the right in Figure 27. This will
leave a space between said naught-carrying arms and the printing segments, into

printing line, or the "oint where the hammer strikes, when any of the printing
segments or their naught-carrying arms are actuated is coincident with the space
between the naught-carrying arms and the printing segments not actuated.
When the type are in position, a hammer is operated to force the paper, upon
which the impression is to be made, into contact with the ribbon interposed
between said paper and type. 72 indicates the ribbon, 77 the paper to be printed
upon, and 78 the hammer for making the impression. I will now describe how
the hammer is operated and how the paper is fed for each impression.
79 Fig. 2 indicates a projection extending from the operating lever 22, to which
projection is secured a sliding piece 80. The sliding piece 80 has pivoted to its
rear end, a dog 81, (Figs. 2 and 7) which is adapted to come in contact with a
tappet 82 secured on the end of a shaft 83 upon which shaft a frame 84 is fixed.
It is in this frame that the spring on which the type hammer is mounted is
secured. A spring 85 is secured to a stationary part and to the frame 84, for
giving force to the blow of the hammer which blow is made by the resiliency of
the hammer spring, said frame being arrested in its movement to permit this.
The operation of the hammer is shown by the dotted lines in Figure 2, which

page_text: illustrates the dog raising the tappet and the hammer elevated to a position to
deliver the blow. This forward movement of the operating lever 22 carries with
it the sliding piece 80 to accomplish the above, and in order to effect the feed of
the paper, I mount in said sliding piece a screw 86, or corresponding lug, which
engages an arm 87, in which arm is mounted a pawl 88 to operate a ratchet
wheel 89, conjoined to the feed roller 90 (Figs. 16, 17). 91 indicates an idle roller
between which, and the roller 90, the feed of the paper is effected. The shaft 83
is supported at its ends by an arm 92, said arm permitting the introduction of the
paper to be printed upon, from the side, whereby, it is possible to print directly
upon the leaf of a book. This shaft 83 is also grooved circumferentially, as at 93,
with which grooves is adapted to co-operate a spring 94, secured to the frame 95,
between whose side bars the feed roller 90 is arranged. The shaft upon which
the feed roller is mounted, is grooved longitudinally, and the feed roller is keyed
thereon, which permits said feed roller being slid longitudinally of the shaft
with the frame 95. By this construction, when a column of figures has been
printed, and it is desired to print another column on the same sheet or leaf; it is
only necessary to move the spring out of its notch, and to slide the feed roller 90,
and frame 95, longitudinally the shaft until the spring 94 engages with the other
recess 93. Of course, as but one means is shown for feeding the paper in but
one direction, the book would also have to be moved back so that the figures of
the new column will start at the top of the page and the page then gradually fed
onward.
I have not shown any means for automatically feeding the ribbon, because such
is a common expedient, and there are many forms of ribbon feed which could
be employed with success.
I have described the operation of the machine for recording, adding and
printing, for it will be understood that the transfer mechanism, as I have termed
it, will add each number printed to the sum total as indicated by all of the
indicating wheels, while the printing segments will print each number separately.
I will now describe how the total, as indicated by the adding wheels, is printed
by the printing segments.
Projecting up from the keyboard at some convenient point, preferably at the
left hand side of the keyboard, is a total key 96 (Figs. 1 to 4), said total key having
connected to it, the end of a lever 97, which lever is pivoted at 98 to the framing
of the machine, as shown in Fig. 3. The rear end of lever 97, carries a cross-
bar 99, which cross-bar is perforated or formed with openings for the passage of
ston bars 100, which are formed with a head at their rear ends between which,
and the bar 99, are interposed springs whose tension is directed to constantly keep
the bars 100 in their rear position. A shoulder on the bars 100 is adapted to
contact with bar 99 to determine this rear position. The forward ends of the
bars 100 pass through openings or grooves in the bar 39, and are in .ine with
snail wheels 101 (Figs. 13 and 14), conjoined to the wheels 16 and 17. The
peripheries of these snail wheels, as I call them, are divided into ten divisions,
cach of which ten divisions is described from the same center, or shaft 18, but
on different radii. I do not wish to be understood as limiting myself to the exact
construction of the snail wheels shown and described, as it is obvious that a
smooth cam 101" having a regular graded surface, as shown in Figure 15, would
perform the same function. The lower portions or members of the printing
segments 65, to which the links 64 are connected, are provided with pins or pro-
jections 102 (Figs. 1 and 13), which are adapted to engage shoulders 103 on the
stop bars 100. The total key before referred to, has connected to it, also, a rock
arm 104 pivoted at 105 in the framing of the machine. Said rock arm 104 being
duplicated on each side of the machine, and carrying a bar 106, which is adapted,
when said total key is depressed, to depress all of the trips 12 and release all of
the rack bars in the machine. When the total key is depressed, its first movement
is to elevate the bar 99 and throw the shoulders 103 of the stop bars 100, in front
of the pins or projections 102 on the lower members of the printing segments. A

page_text: continued movement of the total key will cause all of the trips to release all of
the rack bars as above described, when said rack bars will move forward and carry
with them the lower portions of the printing segments. The shoulders 103 of
the bars 100 being now elevated in the path of pins 102, will also be carried
forward until the forward ends of the stop bars 100 are arrested by the snail
wheels, which determine the position of the printing segments and cause the
character presented under the hammer to represent the step on the snail wheel
with which the stop bar 100 engages.
The lever 22 is now pulled forward, and, through the medium of the mechanism
before described, will cause the hammer to deliver a blow. This movement of the
lever 22 will actuate the adding wheels in the manner heretofore described, that
is, the wheels 16 will be made to engage with the racks 15, unless the lever 28
is moved so as to operate the dog 24 through the medium of the rod 27, which
will elevate said dog so that it will not engage the lever 25 to depress the frame
of the adding mechanism. In this manner the total can be obtained without
disturbing the adding mechanism.
If it is desired to restore the adding wheels to a zero position, the lever 22 is
moved forward a short distance until the adding wheels have engaged the rack
bars. The lever 22 is held in this position, and the total key depressed, or what
would be an equivalent here, all of the "9" keys operated. The release of all of
the rack bars would cause them to move forward and impart a reverse rotatory
movement to the adding wheels, which would continue until the pins 35 were
arrested by striking on top of the hook bars 36, which would establish a zero
position of all of the adding wheels. After this is done, which takes but little time,
the lever 28 is operated to disengage the adding wheels from the racks and the
lever 22 is moved forward to complete a full operation, which, as above described,
would restore the rack bars to their normal position. It is obvious that, as there
is no hook bar necessary for the last adding wheel at the left, some provision must
be made to stop said wheel in its reverse movement. I have shown a stop 36°
yielding in one direction,. to permit the pin 35 to pass, as in its ordinary operation,
said stop, or pawl, as it might be called, arresting said wheel in its reverse opera-
tion, and causing it to stop at zero, as shown in Figure 14.
Whenever the lever 22 is actuated and it causes a movement of bar 34 to the
rear, said bar, near the completion of its movement, will come in contact with a
sliding bar 107, arranged at the side of the machine, which bar 107, co-operates
with a lug 108, extending from rock shaft 109, arranged at the rear of the machine.
This rock shaft 109 operates a link 110, which is connected to the frame in which
the shaft 51 is mounted. The attachment of rods 110 to the shaft 109 is to one
side of the center, so that whenever the sliding bar 107 is moved to the rear by
the engagement of the cross-rod 34 therewith, said shaft 109 is thrown upwardly,
as shown in Figure 6, so that the connection of link 110 is past dead center. By
this means the frame in which shaft 51 is mounted, and the frame 49, mounted
on shaft 50, are each moved upwardly on the principle of a toggle joint. 111
indicates a toothed arm, extending from the shaft 109 into the path of pinion 52,
as shown in Figure 6. A spring 107 is secured to the sliding bar 107, and, to
the frame of the machine, said spring exerting its tension to pull said bar for-
wardly at all times. When the lever 22 is released, and permitted to go back to
its normal position, said bar 107 will be moved forwardly and, after the pinion 52
has completed its work of transferring the numbers from one adding wheel to
another, its final operations is to engage the teeth on the end of arm 111, throwing
said arm rearwardly, as shown in Figure.5, so that the pinion will drop out of the
path of any hook bars which may have been operated between the travels of the
pinion. The object of this is to throw the pinion 52 out of the path of the pro-
jections 42, by causing the depression of the frames 49 and 51ª. This lowering
of the pinion 52 and its shaft 51, occurs only when the pinion is idle and is being
moved from its position at the left of the machine, where, by the time the pinion
has reached said " right" position, the lever 22 will have completed its forward
R

page_text: movement, stored up power in the spring 56, and caused the bar 107 to operate
the projection 108 to throw the pinion 52 into an operative position. When the
pinion completes its movement from right to left, actuating the different adding
wheels, in its path, through the medium of the hook bars and their associate
parts, and reaches its position at the left of the machine, it will throw the arm 111
down and will then be in an inoperative position until moved to the right side of
the machine when the above operation will be repeated.
In the above description I have referred only to the mechanism used for the
purposes of keeping a total of the amounts recorded, such as in the adding wheels,
the mechanism for printing each separate amount recorded, such as the printing
segments and their associate parts, and the mechanism by which the total of
the amounts recorded and of the items printed, could be obtained. I will now
describe the mechanism whereby it is possible to multiply any number by
another.
Pivoted at 112 (Figs. 3 4 and 9) to the framing of the machine, is a lever 113
which is provided at its upper end with a yielding detent which engages a
sector 114, said sector being notched to co-operate with the yielding detent of the
lever 113. The lower end of this lever is slotted to receive a pin secured to a
sliding bar 115, which suding bar supports a detaining bar 116, there being
preferably two of said sliding bars 115, arranged one on each side of the machine
and connected by a cross-rod 117 at their rear ends. 118 indicates links which
are connected to the key bars 4, and to detaining fingers 119, pivoted on a
rod 120, at the front end of the machine.
An
Secured to the lever 113, is a sliding rack bar 121, which is adapted to move
with said lever, when said lever is placed in its desired position, said rack bar
being operated upon by suitable mechanism actuated from the lever 22, to return
the lever 113 to its normal position. This is accomplished as follows:
arm 122, extending from the lever 22, is provided with an inwardly projecting
pin or lug 122 on its outer end, which pin is adapted to come in contact with,
and operate, a pivoted lever 123, said lever 123 being pivoted to the frame of the
machine and normally held against a stop 124, by a spring 125. The forward
end of this lever carries a pawl 126, whose_rear end engages with the teeth of
rack bar 121, while its forward end is concaved and co-operates with a stop pin
127 mounted upon the lever 113. The operation of this mechanism is as follows:
When the keys are depressed, as shown in Figure 4, they also depress their
attached detaining fingers 119. Assuming now that it is desired to multiply a
number indicated by the depressed kevs, by any number within the scope of the
number of notches on the sector 114, the handle 113 is moved to the rear, so that
its spring detent engages with that notch, for illustration, the ninth notch from
the front end of the sector, as shown. This movement of the lever 113 to the
rear, will cause its detaining bar 116 to move forwardly over the detaining fingers
of the depressed kevs, as shown, keeping said keys depressed until the detaining
bar will have moved to the rear a sufficient distance to release said fingers. When
the handle 22 is moved forwardly, the operation of the machine, as before
described, will result, and in addition to said operation, the handle will operate
the lever 113 by the engagement of the pawl 126 with the rack 121. This is
done by the engagement of the pin 122ª on arm 122, which strikes the lever 123,
when the lever 22 is nearing its return stroke, which causes the pawl 126 to move
to the rear, and the detent engaging with the notch in the sector, to move forward,
and engage the next notch in advance. When the operating lever 22 completes
its movement to the rear, under ordinary circumstances, that is, when the
lever 113 is idle, the trips 12 would hold the rack bars in their normal position,
but, as the trips are inoperative, by reason of the depression of the keys, said rack
bars, when the frame of the adding mechanism is permitted to be elevated, and
the racks become disengrд.d therefrom, will move forward again to a position
corresponding to the same position when the keys were first depressed. Another
operation of the lever 22 will move the lever 113 another notch forward, and so on

page_text: will this operation be repeated until the lever 113 reaches the last notch, when the
detaining bar 116 will have released the detaining fingers 119, and the keys are
permitted to rise. In Figure 2, I have shown the parts in such position that the
detaining bar is just ready to leave the detaining, fingers, the lever 113 being in
the second notch on the sector. By the above construction it will be readily seen
that any number may be repeated, as many times as desirable, said number being
added in the adding mechanism and printed. When the number has been
repeated the number of times indicated by the primary position of the detent
relative to the sector, the parts will be restored to their normal position. Of
course, any operation of the lever 22 after the detaining bar has released the
detaining fingers, will have no effect on the several mechanisms in the machine,
except to depress the frame of the adding mechanism, and to move the transfer
mechanism laterally, but as these are inoperative at this time, it may be said
that the machine is now idle.
The use of the above construction in multiplication is obvious, as is illustrated
by the following example, wherein 9,673 has been multiplied by 321.
The operation of the machine in performing this example is as follows: 9673
is depressed on the keyboard, and being multiplied by one, the lever 113 is not
actuated, but the machine performs the ordinary operation of recording that
number. The next depression of the keyboard is 96730 (the zero being automati-
cally placed in position). The lever 113 is now moved to the second notch and
the operating lever is actuated twice. After this number has been placed in the
machine, 9673 is moved another figure to the left and the keys will now represent
967300. The lever is now moved to the third notch, and lever 22 actuated
accordingly. When the total is struck, it will exhibit 3,105,033, the sum total
of the example or the result of these several additions of which multiplication is
but a modified form.

combination of the several parts of my machine can be made and substituted for
