Improvements in Adding Machines.
I, ADAM HOCH, of No. 416, Madison Street, in the City of Toledo, County of
Lucas, and State of Ohio, U.S.A., Salesman, do hereby declare the nature of this
invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
This invention relates to adding machines of that class or description which
are operated through the medium of finger keys to print lines or rows of figures
upon a strip of paper and also to add the figures or numbers as they are printed,
and finally to print the sum total at the bottom of the column.
In carrying out the invention I provide a printing bar having on one face, vertic-
ally arranged, the ten digits, and on another face a rack to operate the gears of the
adding mechanism, which latter is also a printing mechanism, to print the sum
total. Two sets of independently operating keys are also provided, one set serving
to shift the printing bar from the right to the left to the desired starting point,
that being the highest order in the number to be printed in each row; and the
other set of keys will independently operate the printing bar to actuate the add-
ing mechanism, print the desired figure. on the paper and feed the printing bar,
step by step from left to right. The shifting keys also actuate the paper feeding
devices. There is also provided a single key which operates the sum total print-
ing mechanism to cause it to print upon the paper.
The invention will be fully described in the following specification and is illus-
trated in the accompanying drawings, in which:
Figure 1 is a vertical, longitudinal section of the machine; Fig. 2 is a plan
view, the cover being removed; Fig. 3 is a side elevation, partly in section, of
the mechanism to actuate the printing bar, the casing of the machine being

in the desired elevated position and to release the same after a figure has been
printed; Fig. 15 is a plan view of the mechanism shown in Fig. 14; and Fig. 16
is a sectional side view of the adjusting devices for the adding wheels.
Similar reference letters and numerals indicate similar parts in the respective
figures.
The printing bar, a, has a series of type from 0 to 9 on the rear edge, and is
lifted by depressing a key, 10, upon a bell crank lever, e, pivoted to a cross bar 12,
the latter being supported in the sides of the casing.
The bar, a, is slotted to receive a rib on a guide, g, said guide sliding and

page_text: swinging on a fixed cross
bar 13, and a rack, 14, at the fron
edge of the printing bar, a, is adapted to engage one of the gears, 15, of
series of adding wheels h. The printing bar is lifted by means of cam levers,
each pivoted at its upper end on a cross bar, 2, secured in the sides of the casin
and each connected by a rod, 20, to one of the key levers, e, and each provided
with an inclined cam slot, t, to receive a cross bar, 16, of a frame j, pivoted at 17
Two links, 18, pivoted to the cross bar, 16, carry a cross rod, 19, passing through
an car on the printing bar which can thus slide on the rod, 19.
The levers, b, are ten in number and the cani slots are at different inclina
tions so that they will, when operated, move the bar, 16, to different elevations
except that the slot, x, in the lever, b, which is operated by the key which repre
sents the figure "0" is so arranged that it will not elevate the bar, 16, at all
When the key representing "1" is operated the bar, 16, and with it the printing
bar, a, will be elevated, one step, and so on, it being lifted nine steps to bring
the figure "9" into printing position opposite the platen.
The printing bar and its guide also slide on a swinging bar, 21, suspended by
links, 22, 22 from the bar, 13, so that by drawing forward the bar, 21, the type
end of the lever is carried toward the platen, c.
24 is a bar extending across the machine and journaled in the sides thereof,
and on this bar pivoted a frame consisting of side bars, f, and cross bars, f³,
and 25, the bar, f, being connected to the bars, f, about midway their length,
and the bar, 25, near their lower ends. A link, 23, connects the bars, fi and 21,
and the bar 25 bears against the curved edge of a sector, d, pivoted at 45 and
having a notch, 29, and a lip, 30.
At the upper end of the sector, d, is a curved slot, 33, receiving a pin, 34, on
a link, 35, hung to a cross bar, 36, carried by two arms, 37, pivoted on the cross
bar 12, fixed in the casing, and the ends of the key levers, e, extend back of the
bar, 36, SO that on depressing any one key, 10,
drawn forward and with it the link 35, and the sector, d, is thus
the rod, 36, is
oscillated. This results in bringing the notch, 29, opposite the bar, 25, which
then enters the notch with a quick action under the pull of a spring, 38, which
carrries the lower ends of the bars, f, forward, and drawing on the link, 23,
carries forward the bar, 21, and swings back the upper end of the printing bar,
bringing its type against the platen, c.
It will be seen that this cannot result until the printing bar has been lifted
to the proper extent as the bar is locked in place until the notch 29, is brought
opposite to the bar, 25, which can only occur after the key has been fully depres-
sed. The key, however, with the cam lever, b, can return at once to its normal
position, under the action of a spring, 39, the sector, d, remaining stationary
during the first portion of the return movement of the key.
It is important to hold the printing bar in any position to which it is elevated
prior to printing and this is effected by providing the frame, j, with a rack, 40,
having ten teeth or shoulders (one to each figure on the bar) and with this rack
engages a spring pawl, 41, pivoted to the frame of the machine, so that when the
frame, j, with the printing bar has been lifted any number of steps they will be
held in place until the printing is effected. This mechanism is on one side of the
machine adjacent to one of the bars, f.
Adjacent to the sector, d, and swinging on the same pivot, 45, is a second
sector, p, having a slot, 33, through which extends the pin, 34, attached to the
link, 35, and the lower edge of the sector, 7, is a cam edge, y, and is provided
with a notch, 28, which is for a purpose to be hereinafter referred to.
When a key, 10, is depressed the sectors, d, and p move together and when the
bar, 25, is in the notch, 29, of the sector, d, the part of the least radius of the
cam edge, y, of the sector, p, will be engaged with the bar, 25.
pivoted at one end on the pawl, 41, and its free end is held up by a spring, 45, and
A pawl, m, is
is provided with a shoulder, 43. When the bar, 25, is in the notch, 29, the end
of the bar, f, will be engaged with the shoulder 43. As soon as the depressed

page_text: key, 10, begins to return to its normal position under the action of the spring 39,
the link, 35, is carried back, thereby relieving the pressure of the pin, 34, on the
sector, 2, and the lower end of the sector, p, will move forward under the action
of the spring, 31, which is connected to it, and the cam edge, y, of the sector will
force the bar, 25, and with it the bar, f, and pawls, m, and 41, toward the rear of
the machine and thereby release the pawl, 41, from the rack, 40, when the
frame, j, and printing bar can drop. During this movement the upper end of
the printing bar will have moved out of contact with the paper but will be pre-
vented from moving into contact with the gear, 15, because the rearward move-
ment of the pawl, 41, is limited by a pin, 41", and as the shoulder, 43, will remain
engaged with the lower end of the bar, f. until released as hereinafter described.
the forward movement of the upper end of the printing bar will be also limited.
As the frame, j, reaches its lowest position a lug, 46, thereof strikes the top of
the pawl, m, and depresses the latter until the shoulder, 43, escapes the end of
the bar, f, when the latter will be free to be moved by the continued action of
the sector, p, and spring, 31, thereby releasing the segment, d, which assumes its
normal position, and the printing bar, a, then (only after having reached its lowest
position) is free to be swung forward to bring the rack, 14, into engagement with
the pinion, 15. It will be seen that by the means above described the rack cannot
engage the pinion, 15, on descending nor until the printing bar is in its lowest
position. This action occurs on the return of every key except that which prints
the last figure in the row, in which case the sector, d, is not released nor can the
rack, 14, be brought into engagement with a gear. This will be referred to
hereinafter.
Adjacent to the pawl, 41 is hung another pawl, r, having a shoulder, 50, which
engages a lug, 51, on the frame, j, when the latter has descended its full extent
and thus prevents any rebound. An arm, 52, extends from the pawl, r, in position
to be struck by the cross bar, 25, as the lever, f, assumes its normal position when
the rack teeth fully engage the pinion, 15. If this does not occur then the lever, f,
will not fully swing back and as the bar, 25, does not strike the arm, 52, the
pawl, r, will retain the frame, j, and the parts cannot be further operated. In
Fig. 14, the pawl, r, is in the position it would assume after being pushed back
by the bar, 25. This ensures a proper engagement with the adding mechanism
prior to other operations. A spring, r¹, tends normally to hold the pawl, r,
against the lug, 5.1.
The above operations ensue on depressing and then releasing any key, 10, with
the printing bar in position opposite any column. A cross bar, 3, limits the
backward movement of the cam levers, b.
Normally the printing bar is in an extreme position at the right of the machine,
and by means of keys, 55, equal in number to the number of columns of figures
the machine is to be capable of printing, the printing bar can be brought opposite
any desired column according to the position of the key struck. This is effected
through the following described devices:
The printing bar, a, which is carried by the guide, g, sliding on the bar, 13,
is carried laterally step by step by a bell crank lever, s, Figs. 2, 9, 10 and 11
pivoted at 64 and the forked arm, 56, of which receives a pin, 57, on the hub, 58,
of the guide, g;
To the same bar, f, which engages the pawl m, is pivoted a pawl, 60, Figs. 1,
3, 11, which engages a rack, 61, on the arm, 62 of the lever, s. At 64 is also
pivoted à lever, t, carrying an incline, 65, and when the lever, t, moves in the
direction of its arrow, Fig. 11, the incline, 65, comes beneath the end of the
pawl, 60, and lifts the latter away from the rack. The lever, t, is moved from the
keys 55, either of which when depressed depresses a cross bar, 66, of a frame, u,
pivoted at 67 and having an arm, 68, with a slot, 69, in the end, through which
extends the cross bar, f¹. When the inner end of the arm, 68, rises the edge of
the slot acting on the cross bar, f, swings the side bar, f, to carry the printing bar
rack out of engagement with the pinion, 15, of the adding device, so that the

page_text: printing bar can move laterally without engaging either the adding devices or
the platen, the position of the cross bar, fl, in the narrow portion of the slot, 69,
preventing any vibration of the printing bar. An arm, 71, projects downwardly
from the frame, u, and is connected to the end of the lever, t, by a bar, 73, so that
when the frame, u, swings back the outer end of the lever, t, moves forward and
the incline, 65, lifts the pawl, 60, and the lever, t, strikes a pin, 74, on the crank
lever, s, and carries the latter in the direction of the arrow, Fig. 11, and shifts the
printing bar to the left.
The extent or column to which the printing bar is thus shifted depends upon
the extent to which the frame, u, is swung. As the bar, 66, is inclined it will
be carried further in proportion as the key struck is nearer the left of the machine.
The general action of the printing bar, after printing a figure, is first to move
out of contact with the paper, next to drop to its lowest position, then to move one
step to the right, and then, except after printing the last figure in a row, to move
forward into engagement with one of the pinions 15. To the bar, 24, is secured
a notched guide plate, 4, a notch, 140, being opposite each pinion, and the print-
ing bar, a, must enter a notch, 140 before it engages a pinion. After printing the
last figure in the row there is no notch for the bar to enter and consequently it
engages the plate, 4, before it has moved forward sufficiently to release the bar, 25,
from the notch, 29, in the sector, d.
As the printing bar normally is to the right of the first printing column, it
must be shifted (to begin operations) to a position opposite one of the columns.
The notch, 28, is, therefore, provided in the sector, p, so that as the arm, 68,
rises the bar, f, can be swung back carrying the bar, 25, into the notch, 28,
thereby swinging the printing bar clear of the guide plate, 4, before beginning
to shift it laterally.
When the rear end of the arm, 68, descends drawn down by a spring, 77, the
cross bar, f', moves back into the enlarged end of the slot, 69, and the printing
bar rack then engages the adding devices and the bar, 25, is disengaged from the
notches, 28 and 29, in the sectors d and p, and the sector, d, moves back and
locks the bar, 25.
On the return movement of the bar, f, after a number has been printed in one
column, the pawl, 60, engages one of the teeth of the rack, 61, and thus turns the
lever, t, sufficiently to carry the guide, 7, and the printing bar to the next column
to the right.
In order to exactly define the position of the printing bar when shifted to any
column by depressing any one of the levers, 55, each key has connected to it a
stop bar, 90, which is thrust froward on the depression of the key, into position
to be struck by a shoulder or lug 92, of which there is a series on a bar, 93, car-
ried with the arm, 56, of the lever, . The said arm and the printing bar are,
therefore, arrested exactly in the proper position. When the spacing key, 55,
is released the spring, 94, returns it to its normal position and the stop bar is
retracted. The spring, 94, is connected to a downwardly projecting arm, 71ª,
on the key.
The depressing of a key, 55, is made the means of feeding the paper by turning
the platen, c, round which the paper passes. This is effected from a yoke or
frame, 97, hung to the cross bar. 67, so as to be struck by any one of the shifting
key levers and having an arm, 85, connected with a lever, 86, from which a rod, 87,
extends to a pawl, 88, carried by an arm, 89, swinging on the shaft of the platen.
When, therefore, a shifting key is depressed it swings down the yoke, 97, draws
back the arm 85, and rods, 81 and 87, and the pawl, and turns the platen roll
one step. The extent of rotation and amount of feed may be regulated by adjust-
ing a guard plate, 100, secured to the arm of a lever. 101, swinging on the shaft
of the platen, c, the pawl sliding over said plate and only engaging the ratchet
teeth of the platen after its end passes from the edge of the plate.
The carrying and operating mechanism of the adding wheels is best shown
in Fig. 12. Each gear wheel, 15, has twenty teeth, and a hub, 102, the latter

page_text: being provided with two diametrically opposite lugs, 103, one of said lugs being
adapted at each half revolution of the wheel 15, to strike the end of one arm, 104,
of a bell-crank lever, A, the other arm, 106, of which carries a spring pawl, 105,
engaged with a tooth of the adjacent wheel to the left. Every time, therefore,
a wheel, 15, turns to the extent of ten teeth, or half a revolution, the adjacent
wheel to the left will be moved one tooth. There is a lever, A, for each wheel, 15,
except that on the extreme left and all the levers are pivoted on a cross bar, 107.
B is a stationary frame supported adjacent to the adding wheels and forms a sup-
port for a series of slotted carriers, 108, each carrying a spring-pressed bolt, 109.
All the carriers are pivoted to swing vertically on a rod or bar, 110, and each
bolt has an inclined shoulder, 111, adapted to engage a roller, 112, when the bolt
is retracted. The end of the lever arm, 106, normally engages the underside of
the bolt, 109, and holds the shoulder, 111, in engagement with the roller. When,
however; the lever A, is rocked on its pivot by a lug, 103, the arm, 106, moves
out of engagement with the bolt, 109, and permits the carriage to swing down
sufficiently to disengage the shoulder, 111,. from the roller, 112, and the spring
will then project the bolt and cause its outer end to enter between two teeth of
the gear wheel, 15, and prevent it from turning more than one tooth. The
bolt, 109, has also a shoulder, 113, on its lower face which in its forward move-
ment strikes the end of the arm, 106, of the lever, A, and causes it to move for-
ward sufficiently to move the wheel one tooth, the lug, 103, serving only to actuate
the lever, A, sufficiently to release the spring bolt. All the bolts are returned
to operative position by means of the cross bar, 114, which engages the underside
of the arms, 104, this bar being actuated by the lever, 86, whenever one of the
shifting keys, 55, is depressed.
Each of the wheels is independently mounted upon a tubular shaft, C, which
in turn is mounted upon a solid shaft, D. Each wheel has two diametrically
opposite recesses, 115, in the bore of its hub into either of which the bevel end
of a spring-pressed bolt, 116, carried by the shaft, D, is adapted to enter, these
recesses being located in line with the places occupied by the cipher on the face
of the wheels. It will be seen that the wheels can be rotated in one direction
regardless of the bolt and the shaft will remain stationary. If, however, the
shaft be turned in the same direction the wheels are free to move in, the bolts, 116,
will as soon as they enter the recesses move the wheels with the shaft, and thus by
turning the shaft until all the wheels are engaged by the bolts the machine may
be set to zero, that is, the ciphers on the wheels will be in alignment. To enable
the shaft, D, to be turned it is extended at one end beyond the casing and pro-
vided with a milled head, E. In turning the shaft, D), to cause the bolts to enter
the recesses the sleeve will also be turned and during such turning the cord, 117,
will be wound on the sleeve and distend the spring, 118, but as soon as the
shaft, D, is released the spring, 118, will act to unwind the cord and return the
sleeve and shaft in the opposite direction until the shoulder, 119, of the disk, F,
carried by the sleeve. C, engages the pin, 120, on the casing of the machine.
When so engaged the line of ciphers will be in the proper position relative to the
printing platen. The turning of the shaft, D, to bring the bolts into the recesses
in the hubs will be in the reverse direction to that in which the wheels normally
move and it should be so turned one-half revolution as will insure that all the
bolts will become engaged in the recesses on the return movement which is caused
by the spring and cord. Each gear wheel, 15, is also provided with a locking
pawl Z, such pawl being in the form of an elbow lever pivoted in the stationary
frame B. The long arm of the lever is provided with a tooth, , having an in-
clined face and a flat face, which projects between two teeth on the wheel. Such
wheel is, therefore, free to turn in one direction but is locked against movement
in the opposite direction. The tooth is held yieldingly in position by a spring, Z.
The total is printed from a series of printing wheels 121 geared with the adding
wheels, 15, and carried by a shaft 122, of a frame, 123, the slotted side bars of
which swing and slide on the cross rod 13. At the lower end of each side bar of

page_text: the frame 123 are projections 125, 126 between which move rollers 127, carried
by swinging arms 128, one of which is connected by a rod 129, with the lever 121"
of the total key 120. (See Figs. 8 and 9.) By depressing this key the frame 123
is first lifted and then swung to bring the type wheels against the paper on the
platen, c, thus printing the total. The platen c, of course, must be turned a step
prior to printing the total and this is effected by a second feed pawl 130, con-
nected by a rod, 131, to the frame, 123.
A locking detent in the form of a hooked pivoted lever 135, engages the
shaft 122 and holds the printing frame in place until the lever 135, is engaged
by the end of the arm, 62, of the lever s, and the lever 135 is thrown back to
release the printing frame. This engagement of the arm, 62, of lever s, occurs
only when the last figure in a row has been printed, and of course, this occurs
at the end of every row. After being thus released the printing frame 123 can be
moved by depressing the key 120.
The lever, 135, is also provided with a pin, 136, which enters a hole, 137, in
the sleeve, C, on the shaft, 1), and serves to prevent the adding wheels from being
turned to zero until the last figure of any row has been printed.
An inking roller, 145, is supported in any suitable manner from the guide, g,
and is engaged by the printing bar each time the latter is moved toward the
platen, c. The arm, 146, which carries the roller will be supported to yield later-
ally when the printing bar engages the roller, and be provided with a spring to
return it to its normal position after the bar passes out of engagement with it.
An inking roller, 147, for the total printing wheels will be pivotally supported
in the path of travel of such printing wheels to the platen.
Suitable dating wheels 148, may be mounted on the shaft 122, if desired.
It is, of course, to be understood that the total printing wheels and the adding
wheels will always move uniformly in either direction and that when all the
adding wheels are set back to zero the total printing wheels will also be similarly
set back; also that in printing the sum total, if such total is not of the highest
order the machine is capable of registering, ciphers will be printed in all the
spaces to the left of the highest order in such total.
I do not limit myself to the precise forms, constructions and arrangements
herein described, as these may be varied to a considerable extent without depart-
ing from the main features of my invention. For instance, many of the connec-
tions between the keys and parts operated thereby may be changed, the platen
may be carried to and from the printing bar as in other machines, and different
means may be used for supporting, shifting and adjusting the printing bar.
Having now particularly described and ascertained the nature of my said
