In the illustrations similar letters refer to similar parts of the machine.
A is the frame of the machine-B is the galley supported by the frame upon
which the dead matter to be distributed is placed, C is a moveable piece intended to
be set to support the side of the type column and adjustable to the width of said
column, D the channel into which the end or lowermost line of type on the galley
is lifted. E is a plate on which the type slide on their feet as they stand in the
carrier into which they have been thrust by the hammer beneath.each carrier; at the
point where the type is to leave it, is an opening in the plate E into which the type
falls, the lower end of said carrier being open; E? is a plate containing a series of
channels arranged vertically under the openings into which the type fall from the
carrier, which channels conduct them into the openings of the switch plate E' through
which they pass into the elastic tubes E³. E' is a horizontal switch plate which serves
as continuations of the clastic tubes E3 and to support the same; this plate is adjust-
able to different positions and is moved into the desired position at. the will of the
operator to present the mouths of the elastic tubes which are required to conduct the
type in process of distribution to their proper, receptacle ; E³ are elastic tubes
attached at their upper end as just described to plate E¹ and at their lower end to
the grooved plate F intended to convey into the proper grooves thereof the type
intended for the same.
In Figure 7 the galley is shown set at such an angle that the dead matter will
nearly slide down of its own weight as the lowermost line is successively lifted to the
channel D. Should the type not move freely there may be used a weight or follower
behind to urge it down. The piece is moveable and is used to sustain one side
of the type lying on plate B and is adjustable to the width of the column of type and
is held in place by one end thereof passing round and under plate B which forms the
bottom of the galley which part is held in position by the set screw c¹ Figure 3 passing
through the same and binding on the plate. is an enlarged bearing of the piece C
which slides on the end of the bottom plate B of the galley and serves to keep
the moveable piece parallel with the side of the galley aiding the set screw et to
hold the same in place.
D is the channel into which the type are lifted from the galley, extending from. the
gate and where the hammer operates to eject the end type to and along the lower end
of the galley to its outer edge. It is seen in Figures 9 and 10 that the type in the
galley rest against the moveable piece D at their lower end. In Figure 9 it will be
seen that this piece is thinner at the upper edge than at the lower and that, there is
a shoulder at D. When this piece is depressed the lowermost line of type is seen to
have advanced and to rest on this shoulder as in Figure 10. When the same is raised

page_text: to its second position seen in Figure 9 it carries up the line of type resting upon the
shoulder D". When in this position the shoulder D° becomes a continuation of the
bottom of channel D. The remaining body of type stand as seen in Figure 9 in
position to again move down upon the depression of D².
This movement up and down of the piece D shewn in section in Figures 9 and 10
at the will of the operator to supply the type as fast as required in the distribution is
effected as follows:-In Figure is seen a rack attached to each end of the piece D
marked D³ which are actuated by the geared wheels D one at each end of the shaft D.
Partial rotation of these geared wheels is effected by the rack d which engages with
the right hand pinion wheel D this rack at its lower end is pivoted to one end of
the piece d (Figure 8) d' is also pivoted at the other extremity to the frame A of the
machine at d. At the end of d' is seen a pin or small friction wheel 13 that travels
on the face of the eccentric cam d. When the crank is turned to the left it
rotates the shaft carrying with it the cam d³ to which it is rigidly attached. This
rolation carries down the free end of the piece and with it the rack this rack
engaging with the geared wheel D actuates it and the shaft D with the other wheel D
at the opposite end. Both these geared wheels engaging with the racks D³ raise them
and the piece 12 to which they are attached. This as before described carries up with
it a line of type into the channel D. As the rotation of the handle d² continues, it
carries forward the cam until the point of it at d has passed off the small friction
wheel d¹³ do is a spring, one end attached to the frame A. and the other end thereof
operates upon the piece d' near its free extremity to throw it up when the cam d³ at its
point has passed off the friction wheel which movement of the free end of d
effects a reverse movement of the piece D throwing it down so that the shoulder D
again passes under a line of type as seen in Figure 10. D" Figure 7 is a sliding
piece moving freely backward and forward laterally within the chanuel D and when
the line of type has been raised by D it is. standing in the channel D behind said
line. This piece D is held from falling when the shoulder D descends to take the
line of type by a pin in the frame A. working in a groove D2. Pivoted to the end
of this piece D near its right hand extremity is the piece the lower end of which
is adjustably connected to the framework by the stud or pin working in the
-slot in the piece. When the shaft do is rotated by the crank das just
described the cam de being firmly attached thereto is rotated, another small friction
roller on the pin d travelling on the face of this cam d. draws back the piece D" to
allow the lifting of a new line of type into the channel D. When the small friction
roller has passed the point dx of the cam the sliding piece D" is behind the
line of type and in position to be moved forward carrying the line of type just lifted
from the galley into the channel 1) before it. This movement of pushing forward the
line of type is effected by a coiled spring not shown within the drum D. Around
this drum a cord passes and thence round the small guide pulley D1 and thence to
the right hand end of the pusher D when it is attached to the same, by the
pin Di
.
When the rotation of the cam d³ has retracted the pusher Das just explained
to its limit of movement it has acted against the coiled spring in drum D³ to wind
it up. When the roller 12 has passed the point of the cam dx the coiled spring is
free to return the pusher D" to the position shown in Figure 7.
Every complete revolution of the shaft therefore lifts up a line of type into
the channel D actuated as explained and compresses the spring in the drum D
which spring on its release draws forward pusher and the line of type, behind
which it has taken its place toward the hammer end of channel D. And this process
of lifting and pushing forward a line is repeated as often as necessary to supply
type in the channel for the work of distribution. In order that the handle d²
actuating shaft do may be arrested at the right point a stop c provided.. This
stop is shown at c Figure 7 as a spring, one end of which is attached to the piece d'
the free end acting against the handle d² to limit its movement to a single rotation.
Upon handle dis-a moveable sleeve c¹ Figures 7 and 8 which the operator when he

compresses
with the shaft d. The movement of the sleeve c' towards the arm
the coiled spring and engages with the arresting spring cand compresses it thereby
releasing the handle and allowing another revolution thereof.
Figures 14, 15 and 16 show a part of the mechanism for pushing the end type
standing in the channel D out from the line and into a carrier. As the line of type
is pushed or fed forward as just explained, its movement is arrested by the fixed end
piece Do Figure 14. H is the hammer, preferably it has two faces in order to give
two points of contact with the type upon which it acts.
In Figure 15 is seen the piece K into which it is the office of hammer H to
thrust the type at the end of the column. In Figure 4 this hammer is seen to
be pivoted to the piece H which is attached to the frame A. by the pivot A¹
This hammer is actuated by the piece 2 to thrust out the end type before it.
The piece is connected at its other extremity to the arm 3 operated by the
shaft Figures 11 and 13. This shaft is attached to the frame. A. and is
partially rotated to operate the hammer by the arm Figure 13 and by the same
piece attached at the other extremity to the arm / actuated by the shaft H³.
This shaft supported in brackets A³ at each end carries two arms H which at their
extremities carry the piece H Figure 13. This piece H+ lies below and at right
angles to all the levers of the keyboard and close against their under edge. When
any key lever H is. depressed it carries down with it this piece H and thus
actuates the parts just described and the hammer .H throwing it forward and
expelling the type standing before it. The coiled spring on the shaft h* returns
the various parts to their former position, ready to thrust out another type by the
depression of any key lever.
This hammer H was seen in Fig. 4 to be carried by the free end of the piece H'
which is pivoted to the frame A at A¹. Since the thickness of the body of the
letters of a single font varies constantly from a hair space to a capital Wit is
obvious that the hammer must be made to adjust itself automatically to the thickness of
the body of the end letter or space standing before it. This is effected by giving
the hammer a lateral movement. How this is done will be seen in Fig. 13.
Pivoted to the piece H₁ is the piece band this piece at its other extremity, is
pivoted to the arm 6 at 63. The arm is actuated by the shaft which at the.
other end is attached to the arm at 5. This arm is connected at its extremity
with the piece and at the other end to the arm at 3. This arm is actuated
by the shaft 10. At will be seen the piece 12 firmly connected to this shaft.
This piece has a convex face to which is shown to be attached the piece 613 by
This allows by tightening one screw and loosening the other, of
adjusting the inclination of the piece The upper end of 13 is shown as bent.
or cut so as to present an inclined surface to the pivot on which is mounted a
small friction roller. Each lever of the key board carries one of these pins. In
Fig. 13 the pin on the short key lever H is a little further from the fulcrum
of this lever than the one shown on its adjoining long lever H³, this lever being
cut away to show its pin. The movement of the key downward causes this friction
roller to bear upon the inclined face of 13 at their point of contact and throw it
forward; this movement of the upper end of 613 actuates the shaft 610 and through
the mechanism just described moves-the-free end of the piece H which carries the
hammer H.
two screws.
The sole office of this short lever H10 is to operate the mechanism described; to
effect a movement differing in degree from that effected by the lever adjacent to it (H").
On one lever therefore it is only necessary that the pin ti should be set a little further
from the fulcrum H' than that on the other which is shown in position and marked t
(the lever H being cut away) to cause more or less a movement of the arm b¹³ against
which they operate. By adjusting these pins so as to give such movement to 13 as to
swing the hammer on the piece H' to cover the body of the type standing before it
the desired object is effected. This adjustment will depend on the size of the letter
the key represents and is effected by the two adjusting screws connecting the piece 613
to the curved face of 61. In the machine illustrated in the drawings there is shown

page_text: in Figure 2 a key board with 30 keys and 30 supplemental keys carried by short
levers H. This number admits then of 60 adjustments as each lever is adjusted to
effect a movement of the piece 613 through the pins t and t¹ according to the thickness
of the body of the type represented by its key. It need not however be limited to
30 keys and 30 supplemental ones on the key board.
Having shown how the hammer is made automatically to adjust itself to the
thickness of the type body to be pushed out, it will be now shown how the opening or
gate through which the type are pushed out by the hammer is made to automatically
adapt itself to the thickness of the type that is to be passed from the end of the.
channel D to and into the carrier K.
3
In order that the type as it emerges from the channel D may not get out of position,
that is, turn on its side, supports are required to hold it as it moves out. On one
side in Fig. 14, it is apparent that the end piece D00 affords this support extending as
is shown to the left. Fig. 14 shows the supporting piece of the other side of the type
which is called the gate. The piece H2 swinging upon the pivot carries at the free
end two pieces s s¹. In Fig. 14 these pieces and are seen when in place to form a
part of the side of the channel D the ends moving in the slots ss Fig. 16. This
is also seen in Fig. 15 where the end piece D is removed. If then the piece H³
carrying these pieces at its free end be adjusted to move synchronously and equally
with the movements of the hammer just described the exit or channel through which
the type pass into the carrier, is opened or closed as required. This is effected as seen
in Figs. 14, 15 and 16, by connecting together the pieces H¹ and 2 by the small
pieces. The same thing is also effected by making Hand H² a single piece pivoted
at one end at A¹ and the other end carrying both the hammer and the gate. By this
means the opening through which the type is pushed corresponds to the thickness of
the type body which the hammer is adjusted 'to eject.
In the key board. there are by preference employed 60 keys though it is not limited
to this number as it has been found that 180 letters and characters are all of a single
font commonly used, being nearly all of the printers case, and the number is therefore
limited as in the machine shown in Figure 2 to 60 keys. There are in a font of type
say five letters A, to wit: capital, lower case, small capital, italic capital and lower
case. The single key operates to push out into the carrier all these and in addition
thereto a figure, double letter or a mark, making 6 to each key lever. The function
of the short key lever H operated by the supplemental key H Fig. 13 has been
explained as has also the manner in which the depression of the key H of the lever H
actuates the mechanism to operate the hammer to expel the type standing before it,
and to adjust the movements of the hammer and the gate to the requirements of the
type body acted upon.
It has been shown that a single key lever operates to eject 6 characters. It has also
been found that the two movements of the hammer and gate, effected as shown, by
the pins and t¹ and their cooperative connections are sufficient to handle these six.
characters. By these simple ineans it is possible to effect a partial distribution of the
180 characters, into thirty classes of six characters each. It will be next shown how
a further and final distribution is effected.
The key lever H carries upon the end opposite to the fulcrumed end a pin on which
is a friction roller I, acting upon the face of the cam 14 sliown in Figs. 4, 11 and 12.
This cam I is supported on the shaft 12. This shaft is supported at its lower end by
the piece 15 attached to the frame A and the other extremity by the piece 1' also
attached to frame A as shown in Fig. 1 at 17. The effect of depressing the key lover
is to cause a partial rotation of the shaft 12 as the friction roller moves down the face.
of the cam.
This shaft is one of thirty as shown, and the operation of one will
illustrate that of all, as they are in all respects similar. Each of these shafts carries
an arm 13, attached near its upper end as in Fig. 11. The other extremity of this
arm 13 carries the piece 15, having a carrier at its lower end. When the key lever H
5 is depressed and the partial rotation of shaft 12 is effected as just explained, this
piece 1° swings to the position shown in the dotted lines Fig. 11. The arrival of
10
carrier K to the position shown is coincident with the completion of the movement of

page_text: the hammer to push out the type at the end of the line. The effect of these coincident
movements is to land the type within the carrier K standing as in channel D, on its
feet. The moment the key H Fig. 11 is released by the finger, the coiled spring 17
on shaft I carries back the arm to its original position. As will be seen in Fig. 5 at 18
the dotted line shows the path of movement of the carrier K to be the arc of a circle;
all the carriers K are so arranged that these arcs coincide at the point where the
pusher thrusts out the type, so that each carrier gets its type whether the arm carrying
it be long or short. This is obvious from Fig. 5 where a number of them are shown;
also in Fig. 2 where 30 are shown. It will be seen that the arms are arranged along
two sides of an acute angle. Compactness and rapidity of operation are best
attained by having this angle something less than 90° The plate E as shown
in Figs. 2 and 5 is a hard and smooth piece of metal on which the type
conveyed in carrier K which is open at its lower extremity, slide, standing on
end as the arm swings back to its position as seen in Figs. 2 and.5. Arranged in
this plate E. directly under the lower end of these carriers K which are open.
at the lower end as explained, as they stand in the position shown in
Fig. 2, are openings to correspond with the size of type body the carrier
has brought. As soon as the carrier K reaches this position, the type within it
falls through plate E, into a channel, one of which is shown in section in Fig. 11
at 1° 10. Through this channel the type drops into the opening directly beneath I
in plate E Fig. 11, and through this plate and through the channel E³ to its final
resting place in the grooved plate F Fig. 11. The plate E2 shown in Fig. 4 has a
series of channels which serve only to direct the falling type to the opening in
plate E. In plate E2 there are as many channels as there are carriers K bringing
type. This plate 3 is rigidly attached to plate E and is held in position by it.
Directly below the lower edge of E is the switch plate E Figs. 3, 6 and 11. By
means of this switch plate the second step in the distribution of the type is effected.
On emerging from the channels in plate E2 the type enter the openings in the
plate E¹ Fig. 6. It will be seen in this figure that there are six rows of holes of
thirty each corresponding to the six letters and characters as explained above,
delivered by each carrier E. The line of these holes is made to conform to the line
of the holes of exit in E2 above, from which the type emerge as they descend, as just
explained. This switch plate E¹ is supported on the moveable frame E° Figs. 3
and 28. This frame rests on its two extremities on the projections E00 of the frame A
and at its middle part upon the piece E000 attached to the frame A at e Fig. 3. The
two projections and the piece E000 carry friction wheels upon which the frame E"
moves see Figs. 3 and 28. Normally or in ordinary work, the line of holes numbered 1
Fig. 6 stand under the exit mouth of the channels in plate E' and serve to receive the
lower case letters and such other figures or characters as may be desired. If capital
letters are being distributed the line of holes numbered 2 is brought under the
channels in E2 and receive the type as they emerge therefrom and so pass through the
openings of line 2 and through elastic tubes E³ into the grooved plate F below.
When other letters as small capitals or italic caps or lower case are being distributed
the line of holes 3, 4, 5 and 6, intended to receive them, is brought under the
channels in plate E and serve to conduct by the elastic tubes E the falling type into
their proper grooves in plate F. The movement of the frame E° carrying plate.E'
to bring the holes therein to the positions just described, is effected by five keys seen
in Fig. 6 at E and numbered 2, 3, 4, 5 and 6 to correspond with the line of holes.
Since the line of holes that receives the lower case normally stands under the
channels E2 no key is needed. Key number 2 on being depressed moves the frame
carrying plate E so, that the line of holes No. 2 come in position to receive the
descending type, say capitals, and so of the other keys respectively. As seen in
Fig. 22 which is a section of the machine at y y Fig. 6 the key is part of a piece E
held on the shaft E which shaft is supported by bearings attached to the frame A
at E Fig. 22. E' is pivoted at e to the piece e which at its other extremity iş
hooked over a piece e' in arm E carried by the rocker shaft E.
Each of the 5 keys is in the same way attached to rocker shaft E" as seen in

page_text: Fig. 6. The depression of one of the numbered keys partially rotates this rocker
shaft and thereby actuates a single arm el Figs. 6 and 22.. The outer end of this
arin E is pivoted to the piece E¹³; which at its other end is attached to the frame E°
at E Figs. 6 and 22. It will be seen that the depression of any of the numbered
keys Fig. 6 partially rotates the rocker shaft E" and so actuates E¹³ to draw the
moveable frame E towards the operator.
In Figs. 22 at is seen pivoted to an arm opposite to an arm carried by the
shaft E the piece the opposite end of which is pivoted at 2 (Fig. 6) to one arm of
the bell crank lever f3 which is pivoted to the projection of the frame A marked E
The other arm of this bell crank lever is pivoted at to the moveable pin and
actuates it. Through this mechanism the depression of key 2 besides actuating the
moveable frame D° as explained causes the bell crank levor f³ to move so as to throw
the pin fin front of the moving shoulder f on the frame E Fig. C. The movement.
of the pin is timed to arrest the frame carrying plate E at a point when the line of
holes in plate E number 2 are in position to receive the type descending through the
channels of the plate E2. By a similar mechanism key 3 would bring the line of holes
marked 3 in position to receive the type intended for them; and to arrest its move-
ment when it has reached its proper position. In like manner the other keys bring
their respective lines of holes in position to receive the type intended for them and
arrest it there. The coiled spring / returns the frame to the normal position when
the key is released by the finger and the coiled spring f restores the key to the
position in which it stood before depression. The piece is a rod bent to receive
and hold one end of the coiled spring and at its two extremities is attached to the
frame A.
As before explained the rows of holes in the plate E¹ are brought as required in
line under the channels E. by depressing the levers 2, 3, 4, 5 and 6 as required by
the kind of letters being distributed. These holes seen in this plate Fig. 6 are the
openings or mouths of the tubes E³ shown in Figs. 1 and 3 which are attached to the
lower side of E so that each is a continuous channel from said plate to some groove
designated for the particular letter which that channel conducts. In order that this
plate El may move freely it is necessary that the tubes E3 should be flexible and
elastic. This is effected by making them of coiled wire formed into the proper shape
to allow the type which it is to convey to pass freely without turning or getting out
of position as they fall into place as seen in Fig. 11. Plate E Figs. 6 and 11 may
be made of a single piece but for convenience of attaching the tubes and of
removing the same should it become necessary it is preferred to make them in pieces
as shown in Fig. 6 in which each piece is made separate and removeable, the ends
resting on part of the moveable frame E in Figs. 3 and 22. The tubes preferably of
coiled wire compressed upon a former to the proper size, afford all the flexibility and
elasticity required and allow the type to fall through them freely.
-
The wires tubes, for convenience are attached to a piece of thin metal formed as
shown in Fig. 26; the upper end being held in the plate E' by its enlarged end.
The lower end of the wire tube E3 is attached to a piece shown in Figs. 24
and 25; the upper part of this piece in Fig. 25 m³ is bent around the lower end of
the wire tube and holds it firmly; the lower end m³ is bent to form a hook, which as
seen in Fig. 23 engages with the piece attached to the grooved plate Fat m. The
elasticity of the tube E3 holds the hook m³ in position. When the type has descended
into its appropriate groove in plate F Fig. 11, standing on its feet as seen in Fig. 23
at n it must be pushed forward in order to admit the one following it into the same
groove. This is effected by a hammer or pusher F1 for each groove or channel as seen
in Figs. 3, 11 and 23. They are arranged on the shaft F which actuates them to
move each time a key is depressed, slightly forward, sufficient to push forward any
type that may stand before any one of them. There is one of these hammers at the upper
end of each groove or channel which prevents the type that has descended into
5 position falling out as seen in Fig. 23. The plate F is given a little descent so that
the type in the channels when righted upon their feet lean away from the hammer.
For convenience and compactness there should be four plates F each grooved to carry

are to
one quarter of the number of characters to be distributed as shown in Fig. 1. In
the present machine which is here shown and has been tried and found very con-
venient, each plate has 45 grooves or channels. The two upper plates F Fig.
contain the most used characters; and the two lower ones those less frequently
required. When one. of these channels becomes full the type are slid into a moveable
channel and removed to the setting machine.
Motion is given to the shaft F2 which carries the hammers F¹ by the arm g Fig. 3
which is pivotted at its outer end to the rod g. This rod g' is pivotted at its upper
end to the arm g² on a rocker shaft g3 having at its other end an arm go to which is
attached the rod 9 the upper end of which is pivotted to the arm / H" attached
to the shaft H' Figs. 13 and 3. It has been explained how the key lever H actuates
this shaft.. When any key of the keyboard is depressed, motion is given to the arm g³
which is connected to the shaft F2 as explained, and so to the hammers acting at the
upper end of the channels in the grooved plate. F, so that the movement of any key
actuates all the lammers.
In Figs. 17, 18, 19 and 20 is shown another or alternative method of adjusting the
gate opening and the hammer to the requirements necessary to thrust or push out the
end type into the carrier K. In the method already shewn the movements of the
hammer and gate were made to nearly conform to 60 sizes of type bodies. In the
alternative one now shown the thickness of the bodies has been arranged. in nine
classes, so that nine different sized openings and nine different adjustments of the
hammer suffice for ejecting the entire number of type to be distributed. To illustrate:
the lower case letters f, i, j, are in thickness in minion type, between .032 and .038
and t, s, v, between .041 and .047. If we call the first named, class No. 1 and the
second class No. 2, it will be seen that if one adjustment of the hammer and gate
would suffice to expel all the letters of its class, No. 1 for. instance, it would simplify
the mechanism necessary to effect this: All the other letters, figures and marks can
be made to fall within one or another of these nine classes.
At M Fig. 17 is shown a piece M attached to the frame A by the screw X above
the levers of the keyboard and between the keys H8 and the upright shaft 1. This
supports one end of nine small shafts the other ends of these shafts being supported
by another similar piece attached in the same manner as M to the frame A so that the
shafts M' extend across all the levers of the keyboard and at right angles to them.
At M' is seen the arm m attached to the shaft M. Suppose this shaft is designed to
move the gate and hammer for the letters which have been called class 1 whose
thickness is between .032 and .038 of an inch. For each lever of the keyboard
operating to expel a letter of this class, as t, is an arm m as seen in Figs. 17 and 18.
The piece mis pivotted to the key lever H3 at m³. It has an arm projection m*
Fig. 18. The upper end of m² is bent like a hook to pass over the arm m near its free
extremity. The depression of the key lever H would of course carry down the
piece m and the free end of the arm m, partially rotating shaft M. A coiled spring.
on shaft M shown at Fig. 21 returns the shaft N' to the position shown in Fig. 17
when the key is released by the finger. From the other side of shaft M projects the
arm m which at its outer end m³ is pivotted to the upright pin m. It is obvious that
on the depression of the key lever effecting the partial rotation of shaft Mas
explained, the arm m moves up and carries up the pin m which is wedge shaped at
its upper end as seen in Fig. 20. This pin passes through an opening in the frame A
to the upper surface of an opening in a small plate m attached to the frame A which
serves as a guide to said pin. The upper extremity of this pin mo stands just below
the surface of the plate m'. Upon plate m' lies another plate ms held at one end in
position by the pin working in a slot and at the other pivotted to 12 which carries
the gate. This plate has openings or holes to correspond with those in plate m
into which the pin m enters when the depression of the key lever H³ causes it to
rise. The holes in the upper plate m³ are so adjusted with reference to the wedge-
shaped end of the pin me that the latter on entering the hole in the upper plate
draws it back the distance required to open the gate.
Each of the nine shafts DI' actuates a pin and the wedge end of each pin

page_text: actuates the plate m³ to open the gate sufficiently to allow the letters of the class
to which it is adjusted, to pass out. Each shaft M is connected by the arm m and
the piece m² to all key levers H that operate the letters of its class. It has been
explained that H₁ carries the hammer and H2 the gate and that the movement of
these two pieces is over the same distance. If then these two pieces are connected.
together so that the movement of one would cause a corresponding movement of the
other the gate and hammer would automatically assume the nine positions required.
to eject the nine classes of type. Since the supplemental key H° Fig. 17 operates to
open the gate for capital letters whose bodies are thicker than the corresponding, lower
case letter which. key H operates to eject, these two keys must operate in. nearly all
cases shafts belonging to different classes.
L..
The depression of supplemental key H³ carries down with it in all cases, the key H
operating the lever H³, and unless the piece m² were disengaged from the arm m
when the supplemental key were depressed, two levers would be actuated and two
pins attempt to operate upon plate is at the same time. This would defeat the
attempt of the operator to eject the end type. It will be seen in Fig. 20 that the
short lever H is not connected to the same shaft M' as is lever H5 and therefore
actuates a different pin m. In Fig. 18 it will be seen the piece m³ is an arm of a
bell crank lever pivotted at m³ the other arm of which m is actuated by a pin n² in
the short lever H Fig. 20. In Fig. 17 it appears that the supplemental key H³:
stands just above key H³ whilst key His moving down this short distance carrying
lever Ho the pin n² operates upon the short arm m³ Fig. 18 of the bell crank lever m
to depress it and to throw the long arm m² forward and off from the end of mas
seen in Fig. 18. This release of arm m allows the supplemental key H to actuate.
its own arm n³ through the link n' pivotted to H10 (Fig. 19).
n is a small spring which returns the arm m³ to the position seen in Fig. 20 when
the keys Hand H have returned to the position shewn.
