Improvements in Cash Registers and Indicators.
I HERBERT JOHN HADDAN of the firm of Herbert & Co., Patent Agents
of 18 Buckingham Street Strand W.C. London Civil Engineer do heroby
declare the nature of this invention a communication to me from abroad by
The National Cash Register Company of Dayton, in the State of Ohio, United
States of America and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement:-
The novelty of this invention consists in new constructions, arrangements and
combinations of parts, all as will be hereinafter set forth and specifically pointed
out in the claims.

This new machine belongs to that class which employs a driving mechanism
for the indicators and register in combination with a series of banks or rows of
stops or keys, the driving mechanism having a uniform movement at each
operation of the machine and the series of stops or keys operating to determine
the extent of movement which shall be imparted to the indicators and register.
In the machine shown in the drawings there are employed five rows of keys
Fig. 1 nine keys in each row. The keys in each row represent the nine digits,
the uppermost key in the row representing 1 and the lowermost kay 9. Beginning
on the right the first row of keys represents units of cents, the second tens of
cents, the third units of dollars, the fourth tens of dollars, the fifth hundreds of
dollars. By means of these five rows of keys and their co-operating mechanisms
the machine is capable of indicating and registering any desired amount (excepting
fractions of cents) from one cent to $999.99 inclusive.
There are five indicators, one co-operating with each row of keys, and each
bearing the nine digits. The main driving mechanism consists of a revoluble
shaft A Figs. 1, 2, 3 and 4 to which an operating handle B is applied, and a rock-
shaft C which is oscillated forward and back by each revolution of the shaft A in
the manner aud by the means to be described. Fast upon the shaft A just outside
of the right hand side frame of the machine Figs. 1 and 2 is a circular disc D.
י

page_text: Formed upon or secured to the outer. face of this disc is a cam E Fig. 2 and a
surrounding ring F conforming to the shape of the periphery of the cam, and
leaving a cam groove G between them. Fitting into this groove is a friction
roller H mounted on a stud projecting inward from the side of a lever I, which is
pivoted at its rear end to a stud upon the framework at J, and has pivoted to
its front end, the upper end of a link K whose lower end is pivoted to the end
of an arm L fast upon the end of the rockshaft C. It results from this con-
struction that whenever the shaft A is given a complete revolution, the forward
end of the lever I will be first moved downward and then upward, and the,
shaft C thereby oscillated forward and back. Heretofore in machines of this
character the rockshaft has generally been actuated by a revoluble shaft
through the medium of a crank and pitman connection, but I have provided the
means above described for this purpose to cause the rockshaft to be moved at
different rates of speed during different portions of its forward and backward
stroke, and to enable me to regulate its speed during different portions of its
stroke in accordance with the character of the work to be done.
Loosely mounted upon the rockshaft C and held from longitudinal' movement
thereon by suitable collars or other devices are five gear toothed segments Mone
to the right of each of the rows of keys. Fast upon the shaft C one to the left of
each segment, are five hubs N Fige. 3, 4 and 5 each having two upwardly extending
integral cars or plates O P. Fig. 5 between which is pivoted the lower end of a
rocking plate whose upper end projects forward at right angles to the body of
the plate. The upper right hand corner of each plate Q is shaped to form a
tooth R Figs. 3 and 4 which is adapted to co-operate with teeth S formed in the
edge of a segmental flange T on the side of the adjacent segment M, each of the
segments being provided with one of the said toothed flanges. Formed upon
the upper end of each plate Q is a 'lug U which co-operates with the row of keys
standing in line with it and also with a bevelled lug V upon the under side of a
cross bar W of the framework. Formed integral with and extending upward
from the plate or ear O of each of the hubs N Figs. 3 and 5 is a tubular
housing which contains a coiled spring Y (dotted lines Fig. 5) and a plug Z.
The latter has a pointed upper end which bears against the under side of the
top of the plate Q. The engagement of this spring plug with the plate Q serves
to yieldingly hold the latter in the several positions to which it may be rocked
on its pivotal support, and if desired, the under side of the plate may be pro-
vided with shallow recesses to co-operate with the pointed end of the plug. When
the machino is at rest and the parts in normal position, the tubular housings X
stand in approximately vertical position and the upper ends of the plates
thrown to the left as seen in Fig. 3 and yieldingly held in that position by the
spring plugs. In this position of the plates Q, the lugs U upon their inner ends
stand immediately to the left of the vertical planes of the respective rows of
keys, so that as the shaft C is oscillated forward and downward at the beginning
of an operation of the machine, the lugs U will travel along the left hand sides
of the rows of keys. The keys A' consist of short pins mounted in segmental
guides B and having numbered push buttons secured to their outer ends. To
enable the buttons to be made as large as possible, consistent with the length
of the row of keys, the row of buttons is staggered, each alternate button being
secured 'to its key stem near the left hand rim of the button and the others, to
their keys near the right band edges of their rims, as shown.
are
'The keys are frictionally held in their guides so that when pushed inward they
remain in until pushed out again and vice versa. In their outer positions, their
inner ends do not project inward far enough to be engaged by the lugs U even
when the latter are brought into the vertical planes of the rows of keye, but when
any key is pushed inward its inner end will stand in the path of travel of the
lug U.
T
As before stated, in its forward and downward movement, each lug U will
travel to the left of its row of keys, and will therefore clear the inner end of any

page_text: key which may have been pressed in, but just as the shaft C completes its forward
stroke, the left hand side of the upper end of the plate Q will engage a bevelled
lug C¹ projecting rearward from a front cross bar of the framework Figs. 4 and 5
and the plate will be thrown toward the right into what may be called its middle
position and the lug U brought into line with the row of keys. As the shaft C
now moves backward to normal position, the left hand rounded side of the lug U
will engage the operated key, and as it passes it the plate Q will be forced still
further to the right and its tooth O engaged with one of the notches between the
teeth S on the flange T of the segment. This will couple the segment to the shaft C
and the latter will carry the segment with it during the remainder of its return
stroke, at the completion of which the lug U will engage the bevelled lug V on
the under side of the cross bar W and the plate Q will be thrown to the left again
and its tooth R disengaged from the segment.
At the next forward.movement of the shaft Ca lug D' projecting from the right
hand side of the plate which carries the tubular housing X will engage a pin El
Figs. 3, 4 and 5 projecting from the left hand side of the plate F¹ secured to the
hub and one of the radial arms of the segment, and will thus pick up the segment
and carry it forward to the position shown in the drawings. The segment will be
left in this position at the return backward stroke of 'the parts unless some key in
the row corresponding with it has been operated, in which event the plate Q will
be thrown to the right by the engagement of its lug U with such key and its
tooth R engaged with the segment in the manner before described.
It will be understood from the foregoing description that at each operation of
the machine, all the segments which have been moved at the preceding operation
are picked up
and carried forward to the positions shown in the drawings, and all
of them are left in such position excepting those corresponding to the rows contain-
ing the newly operated keys. It will also be noticed that the extent of movement
of each segment is determined by its point of connection with the driving
mechanism and that theso points of connection are controlled by the different keys.
The indicators and register hereinaftor described are geared to and driven by the
segments; and the adjustment of the parts and the relative positions of the keys in
their respective rows are such that each key, when operated will cause the driving
mechanism to be connected with its segment at such point that the movement given
the segment will indicate and register exactly the value of such key.
Meshing with the respectivo segments M are five pinions G G G* G* and G'
Figs. 3 and 4, loosely mounted upon a shaft H' mounted at its right hand end in a
bracket I¹ secured upon the framework and at its left hand end in a bearing upon
the opposite side frame of the machine.
Fast upon the right hand side of each of the pinions there is in this instance a
ratchet wheel J' for a purpose to be explained, while fast upon the right hand side
of each of these ratchets is a bevelled pinion K. Each of these bevelled pinions
meshes with a bevelled pinion L' fast upon a vertical spindle M¹ Fig. 4 journalled
at its lower end in the shaft H' and at its upper end in cross bars NO₁ of the.
framework. The second spindle from the right extends up through the cross
bars N¹; O¹ and is journalled at its upper end in a top cross bar P¹ of the frame-
work Fig. 3. It has fast upon its upper end an indicating cylinder or drum Q
which has the nine digits arranged in order around its face. The other spindles M¹
are short and have fast upon them between the cross bars N¹ O' pinions R' which
mesh with pinions S¹ fast upon the lower ends of vertical spindles T' Fig. 9 which
are journalled at their upper ends in the top crossbar P and carry indicating
cylinders QQQ and Qsimilar to the cylinder Q' before mentioned.
It will be understood from the foregoing description that each of the indicating
cylinders QQ' &c. is geared to one of the segments M and moves in unison
therewith so that the extent of movement of the segment, and consequently the
talue of the operated key is always indicated by the cylinder geared to it.
The numbers on these indicators are exposed to view through reading openings 1"
in the forward side of the machine, Fig. 1. For the purpose of simultaneously

page_text: "
exposing an indication at the rear side of the machine, so that persons standing at
either side may observe the indications, I provide a second set of indicating
cylinders Q, QQ, Q and Q° mounted upon the respective spindles T'immediately
below the cylinders QQ&c. These lower cylinders with the exception of the
middle one Q, are carried by sleeves U¹ U U³ and U⚫ Figs. 3 and loosely
mounted upon their respective spindles, and the cylinders QQ, Q and Q are
geared respectively to the cylinders Q1, Q, Q and Q so that the spindles Q
And Q10 representing units of cents, turn together as do the cylinders Q and Q
representing tens of cents, Q and Q7 representing tens of dollars and Qand Q
representing hundreds of dollars. The middle cylinders Q and Q both represent
units of dollars and they are therefore fastened upon the same spindle and turn
together. The numbers upon the upper cylinders are so arranged that when a
number is exposed at one side of the machine, the same number upon its corre-
sponding cylinder will be exposed at the opposite side of the machine. The geared
connection between the respective cylinders of the upper and lower set may bo
described as follows reference being had to Figs. 3 and 9. The spindle M¹ which
carries the indicator Q and each of the spindles S₁ excepting the middle one
which carries the indicator Q3, has fast upon it above the cross bar O' a pinion V
to V Fig. 3. Pivotally supported upon studs projecting upward from the bar O'
are eight gear toothed segments Wto W the lower four of which W' to W,
mesh respectively with the pinions V' to V which are fast on the spindles M' of
the first, second, fourth and fifth indicators. The upper four segments W to W8
mesh respectively with pinions X' to X fast upon the lower ends of the sleeves U'
to U Fig. 9 which carry the four indicators Q' Q' Q' and Q of the lower set.
The four lower segments W' to Ware connected respectively with the upper
segments W to W by means of four links Y' to Y' so that the respective segments
move together. Through the medium of these segments and connecting links, the
movement given each of the indicators Q' Q, Q' and Q in the upper set is
transmitted to the corresponding indicator in the lower set, as will be readily
understood:
Combined with each two indicators which are mounted upon the same spindle, as
the indicators Q and Q, Q' and Q &c., is a double oscillating screen. These
screens are composed of supporting plates A' Fig. 8 loosely mounted upon the
upper ends of the spindles which carry the indicators of the upper set and extending
diametrically across the indicating cylinders and each having depending from it two
vertical screen plates B' curved to fit the surface of the cylinder. All of these
screens are connected by a horizontal plate C3 which is pivoted to the supporting
plates A of the screens so that all of said screens will be moved together. The
plate Chas connected to it a spring D' which tends to move it to the right and carry
the screen plates B2 to positions directly in front and in rear of the indicators, and
thereby hide the numbers thereon, but the plate C2 is held to the left, against the
stress of the spring D' to expose the numbers on the indicators by means of a
lever E Figs. 1 and 3 to 6 pivoted to the cross bar N¹ of the framework at F Fig. 3.
The lower end of this lever (or a plate secured to its lower end) is bent to the
left beneath an arm G fast on the rockshinft C. In the normal position of the
parts, when the machine is at rest, the engagement of the arm Go with the bevelled
upper surface of this bent end of the lever E holds the lower end of said lever to
the right and its upper end thrown to the left, to the position shown in the drawings,
in which position the upper end of the lever will hold the plate C thrown to the
left, and all of the screens in position to expose the numbers on the indicators, but
when the rock shaft C is moved forward at the beginning of the operation of the
machine and the arm G thereby carried away from the lower end of the lever E³,
the spring D will throw the plate C to the right and carry all of the screens to
positions immediately in front and in rear of the iudicators, and hide their numbers.
Just at the completion of the operation of the machine and backward stroke of the:
rockshaft C, the arm G will re-engage the lower end of the lever E and throw it to
the right, thereby moving its upper end and the plate C³ to the left and carrying

page_text: the screens back to the positions shown in the drawings, to expose to view the
numbers upon the indicators which represent the indication.
A pin H Figs. 3 and 5 projects laterally from the side of the bracket 1¹ in rear
of the lever E and prevents the arm G from forcing the lower end of said lever
rearward when the arm G engages it at the end of the backward stroke of the
said arm.
As seen in Fig. 1 the forward side of the casing of the machine is provided with
a series of windows or reading openings I one immediately in front of each of the
indicators Q', Q &c. of the upper set, through which openings the numbers upon
the indicators are exposed, and between which openings and the indicators, the
screens above described are moved at the beginning of the operation of the machine.
The rear side of the casing is provided with a similar series of windows immediately
opposite the indicators QQ' &c., of the lower sot.
Heretofore in machines employing segments coupled to and uncoupled from a
driving mechanism at different points determined by the operated keys, the
indicators geared to the segments have been mounted to oscillate upon a horizontal
axis parallel to that of the segments, and so far as I am aware, I am the first in the
art to mount the indicators upon vertical spindles geared to such segments. Such
being the case, this invention is not restricted to details of construction or arrange-
ment of the parts, nor to the character of the connecting devices between the
driving shaft and seginents. Those which I have shown and described are not new,
and any other known or suitable devices may be employed; operating either to
connect the driving mechanism with the segments at different points and disconnect
them at a fixed point, as described in this application, or to connect them at a fixed
point and disconnect them at different points as may be done in a number of well
known wayB.
Fast upon a rock shaft J2 journalled at its opposite ends in the side frames of the
machine, Fig. 4, are a series of locking dogs K', which co-operate with the
ratchets J' fast upon the sides of the pinions G heretofore described. Fast upon
the shaft J near its right band end Figs. 3, 5 and 6, is a pendant arm L' in. line
with a friction roller M' carried upon a stud on the side of the rear end of the
arm G. When the machine is at rest and the parts in normal position the friction
roller M on the rear end of the arm G engages the lower end of the arm L³ and
holds the shaft J rocked forward and the locking dogs K³ in engagement with the
ratchet J' but when the machine is operated and the forward movement of the rock
shaft C carries the arm G away from the arm L, a spring N connected at its
forward edge to a pin or screw 02 upon the upper side of the shaft J at its left
hand end, Figs. 4 and 5 will rock said shaft rearward until the pin O' engages a
pin Fig. 4 projecting inward from the side frame of the machine and will thus
lift the locking dogs K out of engagement with the ratchets J'and hold them out
of engagement until the operation of the machine has been nearly completed, and
the arm G re-engages the lower end of the arm L' and rocks the shaft J' again
and throws the dogs K' into engagement with the ratchets J'. Thus at the com-
pletion of the operation of the machine, the segments and indicators are positively
locked in the positions to which they have been moved. Loose upon the hub of
each of the pinious G¹ G &c. to the left of the pinion, is a registering wheel R'
bearing upon its periphery a cipher and the nine digits. Fast upon the right hand
side of each of these registering wheels, beneath the flange which forms its
periphery is a pawl S Fig. 12 which is pressed by a spring T into engagement
with a ratchet V2 fast upon the left hand side of the adjacent pinion. It results
from this connection of the pinions with the registering wheels that as the pinions
are turned forward by the backward movement of the segments M, their ratchets
will carry the registering wheels with them, and register the amounts indicated, but
as the pinions are turned backward at the beginning of the next operation of the
machine, by the forward and downward movement of the segments, the ratchets V*
will slipidly under the pawls S and the wheels R will remain stationary. Spring
pawla W Fig. 5 fastened to the cross bar W of the framework, and engaging

page_text: ratchets X fast upon the left hand sides of the registering wheels R' prevent back-
ward movement of said wheels.
Suitable transfer mechanism, which need not be here described in detail, is
interposed between the respectivo registering wheels to add the revolutions of each
wheel upon the next higher wheel as is usual in this class.of machines.
Fastened to the hub of each of the segments M by radial arms A³ or formed
integral therewith, is a second segment B Fig. 5 approximately opposite the
segment M as seen in Figs. 1, 3 and 7. These lower segments B mesh respectively
with pinions C3, C4, C, C and C' carried by sleeves upon a shaft D' mounted in
brackets E' upon the bottom frame plate F' of the machine. The pinions C³ C* &c.
are employed to drive a series of printing wheels H³, H, H, H and H. The
sleeve which carries the pinion C³ has fast upon its opposite end' a pinion I³ which
meshes with a pinion J fast upon the right hand end of a sleeve K' loose on. &
shaft L, Fig. 5, mounted at its right hand end in a bracket M' and at its left hand
end in one of the brackets E before mentioned.
The sleeve Khas fast upon its left hand end the type wheel H³ representing
units of cents. The sleeve which carries the pinion C bas fast upon its left hand
end a pinion N which meshes with a pinion 3 fast upon the left hand side of the
second type wheel H representing tens of cents. The pinion C which is driven
by the middle one of the segments B' meshes directly with a pinion P³ fast upon
the left hand side of the third type wheel H' representing units of dollars. The
sleeve which carries the pinion has fast upon its right hand end a pinion R
which meshes with a pinion S³ fast upon the left hand side of the fourth type
wheel He representing tens of dollars; and the pinion C7 meshes with a pinion T
fast upon the left hand end of a sleeve V3 which has fast upon its right hand end
the fifth type wheel H7 representing hundreds of dollars. All of the type wheels
are geared to the respective segments and move in unison with the indicators, so
that when the machine is operated to bring to the reading openings any given
numbers upon the indicators, corresponding numbers on the type wheels will be
brought to the printing point. Mounted upon the sleeve V₁ to the left of the type
wheels above described, are three dating wheels W, X³, and Y the former bearing
numbers representing years, the second, numbers representing days of the month,
and the third abbreviations of the names of the months. These dating wheels may
be turned, to change the dates to be printed by them by means of key or short
levers Z pivoted in the frame A in front of said wheels and having pawls B
(dotted lines Fig. 5) hung on their rear ends and spring pressed into engagement
with ratchets C Fig. 7, fast upon the sides of the wheels. The rear ends of spring
holding pawls D secured upon the upper side of the frame A' engage the upper
sides of the ratchets Cand prevent backward movement of the wheels.
One or more inking ribbons E carried upon spools Fjournalled between ears G
upon the sides of the brackets M³ and E³ are passed beneath the row of printing
wheels.
An impression platen I Figs. 2 and 5, is carried upon the forward crossbar of a
frame Jwhose side arms are hung upon a shaft K. The frame J is actuated by
a cam or eccentric Figs. 5 and 10, upon a revoluble shaft L journalled at its opposite
ends in the side frames of the machine and extending across the rear of the
machine Fig. 4. The right hand end of this shaft projects outside the right hand
side frame of the machine, and has fast upon it a gear M Fig. 2 which meshes
with a gear N' mounted on a stud on the outer side of the frame. The gear N*
meshes with a row of teeth 0 upon the periphery of the disc D heretofore
described, and the proportions and adjustment of the parts are such that the teeth
on the disc D will engage the gear N and turn the latter and the gear M and
shaft L' one complete revolution during the last quarter of a revolution of the
operating handle B and disc D. A disc P' secured eccentrically upon the shaft L₁
near its middle, Fig. 10, is surrounded by a ring R* carried by the upper end of a
rod or plunger S whose lower end fits within a tubular a tubular housing T
containing a coiled spring V"confined between the lower end of the plunger S and

page_text: the bottom of the bore in the housing T. The lower end of the housing T' is
pivoted to the rear cross rod W of the frame J. A pin X is passed transversely
through the lower end of the plunger St and projects at each side through slots Y'
in the housing T
It results from this construction, that just before the stroke of the operating
handle is completed, during the last quarter thereof, the rear end of the frame J
will be depressed and its forward end carrying the platen I be thrown upward, to
press the platen (or the interposed inking ribbons and paper strips or tickets)
against the type wheels to print the amount which has been indicated' and registered
at that operation of the machine.
The printing mechanism above described may be employed to print the amounts
of the sales upon paper tickets inserted from the front of the machine between the
platen J and type wheels, and in Fig. 1 there is shown an opening Z between the
upper and lower guide plates, in which such tickets may be inserted for that
purpose; but I prefer to employ this mechanism more particularly for printing the
amount of the sales upon a series of paper strips carried in rolls in the lower part
of the machine, as seen in Fig. 2 and led from said rolls between the impression
platen and type wheels, from which latter point one of the strips is led back into
the machine and wound upon, a storage reel to preserve a record of each sale, while
the others are led over a writing tablet where the different items constituting the
sale may be written upon the upper one and duplicated upon the lower ones by
means of interposed manifolding material, and the strips then torn off to form
detached checks. In Fig. 2 there are shown three rows of these paper strips A* B*
and C⚫ journalled in a frame D' hinged at its rear upper corner to the base plate of
the machine and detachably secured thereto at its forward end in some suitable
manner. From the rolls A B and C the paper strips are led over the roller or
shaft at K which may be the same shaft upon which the frame J is pivoted, and
are led thence forward across the platen 1 and between the inking ribbons E
passing transversely beneath the type wheels. From this printing point the lower
strip, from the roll C is led over the roller E' and thence down around a storage
reel F journalled in the forward side of the frame D'. The two upper strips from
the rolls A and B are led from the printing point over a table or writing tablet G'
upon the upper forward side of the frame D, where a suitable transfer sheet, not
shown, is interposed between the two strips, to cause the items entered upon the
upper strip with a pencil to be duplicated upon the lower strip in the usual
manner.
A knife bar H having a serrated tearing edge is hinged by side arms at either
end to the sides of the table G³ at its forward upper corner, and the strips of paper
are led beneath this bar, which has a handle J by which it may be swung upward
to permit the strips to be drawn forward by hand and then swung downward to
confine them between its tearing edge and the forward end of the table so that
they can be torn off.
The storage reel F has fast upon it a ratchet K³ which is engaged by the
forward end of a pawl arm L' which is pivoted at its end to a lever M³ whose
lower end is pivoted to the side of the frame D' at N° and whose upper end extends
up between the side arms of the frame J into position to be engaged by the lower
end of an arm O' fast upon the rock shaft C heretofore described.
A spring P connected at its forward end to the lever M and at its rear end to
the side of the frame D' tends to pull the lever rearward, but in the normal
position of the parts the engagement of the lower end of the arm O with the
upper end of the lever prevents rearward movement of the latter. A flat spring R'
secured to the lever M³ bears against the under side of the pawl arm L' and holds
its forward end up in engagement with the ratchet of the storage reel. A
holding, pawl S pivoted to the frame D' and pressed by a spring T into engage-
ment with the ratchet of the storage reel, prevents backward movement of
the latter.

page_text: Under the construction and arrangement of the parts above described, the
mode of operation of the machine is as follows.
When a sale is made, the clerk enters the various items thereof, and such other
memoranda as is desired, upon the outer strip above the tablet Go, and the matter
written upon this strip is duplicated, by the transfer sheet upon the lower strip.
The clerk next presses in the proper keys in the several rows to indicate and
register the total amount of the items of the sale, and then gives the operating
handle a complete revolution. This will cause the indicators to expose to view the
numbers representing the amount of the sale, and its full value will be added upon
the registering wheels. There will also be printed upon the three paper strips
passed beneath the typo wheels, the gross amount of the sale, and the year, month
and day thereof. The clerk next throws up the knife bar H by means of its
handle J, grasps the ends of the two paper strips which have rested beneath said
bar, and pulls forward the strips until the date and numbers printed upon them by
the typewheels are brought in front of the knife bar. He then depresses the latter
and tears off the strips against its edge, thereby producing two detached checks,
each having written upon it the various items of the sale and other desired
memoranda and having also printed upon it the date, and the total of all the items.
At the beginning of the operation of the machine the forward movement of the
rookshaft will have carried the arm O' rearward, thereby permitting the spring P
to pull the lever M rearward until arrested by a stud U upon the side of the
frame D' and drawing the forward end of the pawl arm L backward into engage-
ment with a new notch in the ratchet K. When the shaft C was rocked backward.
to normal position, the arm 05 re-engaged the upper end of the lever M' and
moved it and the pawl arm L' back to normal position and caused the latter to
turn forward the storage reel and wind upon it the portion of the record strip
drawn from the roll C.
The remaining feature of this invention relates to the operating handle by which
the driving shaft of the machine is given its revolutions. As seen in Figures 1
and 11 this handle B carries at its lower end upon a laterally projecting spindle A,
the usual grasping knob B. In a bore in the left hand portion of the spindle A
is fitted a sliding rod C between the right hand end of which and the inner end of
the bore is confined a spiral spring D which normally forces the rod C to the loft,
in which position the end of the rod projects through the vertical plane of the
outer end of a stud or stop lug E' upon the framework. The rod Co has a slot F*
cut through it near its middle and a pin L® is passed through the rod and slot
transversely of the latter.
This pin fits in a notch in the side of a rod J* fitted to slide in a suitable guide-
way in the lower end of the handle and passing through the slot F in the rod C*.
One side of the notch in the rod J is bevelled to form a cam surface which
co-operates with the pin L'. In the normal position of the parts the left hand end
of the rod Co rests immediately behind the stop E. When the machine is to
be operated, the operator grasps the knob B, and with his thumb presses in the
rod whereupon the bevelled side of the notch in the latter, bearing against the
pin L, will force the rod C to the right, against the pressure of the spring D' and
withdraw its left hand end from the plane of the stop E°, whereupon the handle is
free to be moved forward.
Heretofore, in machines of this character, the operating handle has usually been
provided with a sliding grasping knob whose spindle co-operated with a stop lug on
the frame to arrest the handle when it has been given a complete revolution. In
such machines, the grasping knob was slid outward away from the framework, to
disengage its spindle from the stop lug and permit the handle to be revolved, a
suitable spring operating to slide the handle back to normal position and bring the
end of the spindle into position to engage the stop lug when the revolution of the
handle was completed.
The objection to this construction is, that the operator is liable to inadvertently

page_text: hold the knob slid to its outward position during the entire operation of the
machine, or if he does not do that, he is liable to accidentally move it to that
position during the operation of the machine so that when the handle comes around
to normal position, the end of its spindle will not be in position to engage the stop
lug upon the frame and the handle will be moved too far.
In the construction which I employ, the grasping knob of the han lle does not
slide toward and from the frame to carry the end of its spindle into and out of
position to engage the stop lug, and the rod C is withdrawn from the plane of the
stop E solely by pressure upon the rod J. This pressure can be conveniently
applied only when the handle is in approximately its normal position of rest.
After it has been moved from such position in the operation of the machine, the
thumb of the operator slips off the end of the rod J and the spring De immediately
throws the rod C to the left, and there is no danger then of its being accidentally
moved to the right again.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is.
