Figures 23, 24, 28, 29, 34, 35, 36 and 37 are drawn to an enlarged scale.
In the drawings A is the base plate or bed of the machine provided with the
two upwardly projecting ribs A¹, A¹, cach having formed in its outer vertical face a
shallow longitudinal groove a; said ribs have formed therein a series of bearings in
which are fitted a series of short shafts each carrying a pair of anti friction trucks b
so arranged that their peripheries project slightly above the upper edges of said ribs
as shown in Figure 2.
B is a carriage, consisting of a rectangular plate which rests upon the anti-friction
trucks b, b, and is provided with two downwardly projecting ribs c, c, each having
formed thereon or secured thereto the inwardly projecting lift c¹, which fits into the
groove a and serves to guide said carriage in its movements to and fro upon
the bed.
Said carriage B is also provided with two upwardly projecting ribs d, d, in the
outer vertical face of each of which is formed a longitudinal groove to receive the
inner edge of a longitudinal bar e, of the upper carriage C in suitable bearings C1, C1,
of which is mounted the paper carriage roll D having its periphery covered with
rubber or other suitable elastic material in a well known manner.
E, E are two goose-neck like stands secured upon the base plate A and to the
rear ends of which the casing of the head of the machine is pivotted at E¹ and
locked in a fixed position by the spring pressed bolt E2 all so arranged that when
locked in its normal position the base of said head and the plane occupied by the
finger keys shall be inclined toward the front of the machine as shown in
Figure 2, for the purpose of rendering the keys more conveniently accessible to
the operator.
The casing or frame of the head of the machine is composed of the base ring F
the cap ring F¹ the thin sheet metal panels or middle section F2 and the central
cap plate or cover F3 as shown in Figure 2.
Upon the upper edge of the base ring F are secured a series of twenty six
brackets G each provided with two downwardly projecting ears f,, between which is
pivotted the short sleeve G¹ so that it may be moved in a vertical plane only.
In each of said sleeves G' is fitted, so that it may be moved about its axis but
cannot be moved end wise in said sleeve, a type bar H provided with a shoulder to abut
against one end of said sleeve and having secured upon its outer end a bevel
pinion g the hub of which abuts against the other end of said sleeve as shown in
Figure 6.
The inner end of the type bar H is made triangular in cross section and has
formed thereon in relief a capital letter, a small letter, and a figure, punctuation point,
or other character.
The inner end of each of the sleeves G¹ is provided with the downwardly projecting
car g' to which the bifurcated lower end of the key spindle I is pivotted as shown in
Figures 2, 4 and 6.
The spindles I are fitted to bearings in the screw bushings set in the cap-ring F¹
and have secured upon their upper ends the key buttons I said keys and spindles
being arranged in a circle and equidistant from each other as shown in Figure 1.
The keys and type bars are maintained in their normal or elevated positions by the
wire springs h one end of each of which is set in a hole in or secured to one of the
brackets G and the other end is inserted in a hole extending transversely through a
spindle I as shown in Figure 6.
Each spindle I is made in two parts pivotted together and to one end of a lever J

page_text: just below the bushing 1, said lever J being provided with a slot through which
passes the wire ring-like fulcrum-pin J common to the whole series of said levers, said
fulcrum ring being fitted to a circular groove formed in the under sides of a series of
downwardly projecting lugs j formed upon the under side of the central cap plate F*
and so shaped as to serve as guides to separate and keep at equal distances apart the
levers J, said fulcrum ring being secured to said lugs by means of screws set in
certain of said lugs with one side of their heads bearing in recesses formed in the
outer side of said fulcrum ring as clearly shown in Figures 28 and 29.
The inner ends of the levers J are curved downward and terminate in upwardly
projecting noses or tips which when the key is depressed come in contact with
the lower end of the short central spindle J and move it upward in its bearing in the
cap plate F³.
The spindle J2 is provided with an annular flange at its lower end and has formed
therein the slot ¹ to receive the inner end of the lever K which is pivotted to the
ears 10 cast upon or secured to the under side of the cap ring F and has its lower end
forked, and its inner end pressed downward by the spring all as shown in Figure 4.
LL are a series of space key levers pivotted to studs set in the cap-plate F³, and
arranged radially around the spindle J with their inner ends beneath the collar 3
secured to the upper end of said spindle J2 so that by depressing either of said keys
the spindle J and lever K may be operated to feed the carriage independently of the
operation of the type bars whenever it is desired to leave a space between words.
By virtue of the slot in each lever J and the positive connection of the outer end
of said lever to the key spindle I, the nose k of said lever will move very nearly in a
straight vertical line when the key is depressed thereby materially reducing the
friction between said nose and the spindle J.
L' is an annular or ring gear fitted to a suitable bearing on the base ring F and
with which each bevel pinions g engages when its type bar is in its normal or elevated
position as shown in Figures 2 and 4.
The base ring F is provided with the curved slot directly beneath the ring gear I,
through which the radially projecting arm L is secured to said ring gear by the
screws, as a means of moving said ring gear a limited distance in either direction
about its axis for the purpose of partially revolving all of the type hars
simultaneously.
The arm L has set in its underside a pin m provided with a head composed of two
long laterally projecting arins m¹ sufficiently removed from contact with the under
surface of said arm to permit the insertion between said parts of the free ends of the
two wire springs n secured to the underside of the base ring F by the screw
studs n', n' around which said springs are coiled in such a manner as to press with
considerable tension against opposite sides of the pin m as clearly shown in Figures 2,
8 and 9, by virtue of which arrangement of parts the arm L is maintained in its
normal position centrally of the slot unless forced in one or the other direction
therefrom which action increases the tension of the spring upon the side towards
which said arm is moved the other spring being prevented from following up the
pin m by coming in contact with the pin o and when the pressure or force is removed
from the arm L² the spring immediately returns the arm L² to its normal or central
position.
:
When the arm L is in its normal or central position the type bars are in position
to print the small or lower case letters if they are depressed. If the arm L be
moved in one direction from said central position all the type bars will be rotated one
third of a revolution and bring the capital letter faces of said bars into position to
print when said bars are depressed, and if said arm L is moved in the other direction
from said central position the type bars will be rotated one third of a revolution in
the opposite direction and bring the faces of said bars upon which are formed the
figures punctuation points etc. into position to print when the said bars are depressed.
M is a three armed lever pivotted at o' to the stand M¹ secured to the exterior of
the base ring F at the front side of the machine the lower arm of which is bifurcated

page_text: and embraces the outer end of the arm L2 and the other two arms extend obliquely to
the right and left of the pivot about which it may be vibrated and are each provided
with a suitable broadened pad like surface in a convenient position to be pressed by
the thumb or finger of the operator to move the ring gear in either direction to
partially rotate the type bars.
The lever M is provided with a pin p set in a bearing therein with a spring p¹
arranged to press said pin into a detent notch in the stand M' when said lever M is in
its normal or central position as shown in Figures 2 and 8.
Upon the inner face of the upright portion of the base ring F are formed or
secured a series of inwardly projecting vertical ribs, the inner edges of which are
curved to an are of a circle struck from the pivotal axis of the type bar the number
of said ribs correspondingly to the number of type bars used and the centre of each
rib being in the same vertical plane as the axis of a type bar.
Each bevel pinion on a type bar has formed in the outer end of its hub three
grooves 77 crossing each other at the axis of said gear as shown in Figure 5
with one of which a rib y on the inner face of the base ring F engages whenever a
type bar is depressed for the purpose of correcting any inaccuracy in the movement of
the type bar about its axis in changing from small letters to capitals or figures or
vice versa said grooves being made slightly flaring at the periphery of the hub to
ensure engagement with the ribs q.
NN are two flanged drums mounted upon shafts ", ", so as to be movable length-
wise thereon, and revolve therewith, and shafts having bearings in the stands NN1
secured to the base-ring F; one upon the right hand, and the other upon the left hand
side of the head of the machine, as shown in Figures 1 and 7.
Each drum N has formed upon one end a hub 2 in a radial hole in which set the
loose pin ³ upon the outer end of which presses the curved leaf-spring n³ secured by
one end to said hub, and the inner end of said pin n³ extends into the spline groove
formed in the shaft to cause said drum to revolve with said shaft, and said pin also
engages with one of a series of detent notches formed in the bottom of groove
hold said drum in any desired position upon said shaft, relative to its length, all as
shown in Figures 15 and 16.
to
Each shaft has mounted thereon a ratchet wheel having teeth so arranged
that the hook pawl engaging with said teeth upon the outer side of said wheel when
moved downward will rotate its drum so as to wind the ink ribbon O upon the upper
side thereof.
O¹ and O2 are two pawl like levers pivotted respectively at 7 and 8 and each having
pivotted to its outer end a hook pawl the upper end of which is drawn towards the
ratchet wheel by the spring shown in Figure 7.
P, P, are two stands secured, one to each of the goose-necks E, and each having cut
in its outer end two open slots p2 and 3 of different depths, the slot p² being designed
to guide and steady the upper end of the pawl when it is in engagement with the
ratchet wheel as shown at the right. of Figure 7. and the slot p³ being designed for
holding said pawl out of engagement with the ratchet wheel as shown at the left of
Figure 7.
By this arrangement of pawls and ratchet wheels the ink ribbon O may be
intermittently and automatically wound upon the drum at the right hand
side of the machine until it is all unwound from the opposite drum, when by
simply placing the right hand pawl in the slot p³, and the left hand pawl
in the slot p, the ribbon will be automatically wound upon the left hand drum,
the paw being moved up and down by the vibrations of the levers Of
and 2 caused by the action, upon their inner ends, of the teeth of the ratchet
wheel P as it is intermittently rotated in the direction indicated by the arrow
on Figure 10 the inner end of the lever O2 heing formed and arranged to abut against
the shoulders of the teeth of the ratchet wheel P' like an ordinary pawl and the
inner end of the lever O' having formed thereon a hook or shoulder to engage with
the same tooth of said ratchet wheel as the end of the lever 02 engages with, whereby

page_text: said levers and Q* are made to serve the double purpose of stop pawls to prevent
a backward movement of the ratchet wheel P¹ and to intermittently move the ink
ribbon as above described.
P2 is a horizontal shaft mounted in bearings in the ribs A¹ A' of the base A and
having firmly secured thereon the escapement wheel P³, the ratchet wheel P¹, the
collar P and the clutch disc P and loosely mounted thereon so that it may be
revolved freely in one direction thereon the toothed gear wheel Pe all as shewn in Fig. 2.
The gear wheel P engages with a toothed rack O, found upon or secured to the
under side of the carriage B so as to be rotated by the movement of said carriage and
is connected to the clutch disc P by means of the grip dog s―the inner end of which
rests in a detent notch pt found in the hub of the gear wheel Pe and having formed
in the edge near its outer end a transverse parallel sided notch or slot to receive and
embrace the annular lip on the clutch disc P5 said dog being made to grip the
said lip by the tension of the springs and any attempt to move the gear wheel about
its axis in the direction indicated by the arrow on Fig. 24 will cause the shaft. P² to
rotate about its axis a distance equivalent to one tooth of the escapeinent wheel P³
provided the escapement is so operated as to permit such movement. R is the
escapement bar or plate slotted at one end so as to embrace and be guided in its
movement by the hub of the escapement wheel 13 and connected at its other end to
stud s³ set in a slots formed in the lower end of the upright lever R¹ pivoted to the
stand R² and provided at its upper end with the pin s³ to engage with the forked
lower end of the lever K through which the motion of a type or space key is
transmitted to the escapement bar to cause the escapement dogs t and t¹ to alternately
engage with the teeth of the escapement wheel upon opposite sides thereof. It will
be observed that a peculiarity of this escapement is that the escapement dogs move
substantially in right lines, and both move in the same direction, and the throw of
said dogs may be varied by adjusting the studs in the slots to a greater or less
distance from the fulcrum of the lever R¹.
The gear wheel Pe is lightly pressed towards the clutch disk P' by the tension of
the spiral spring surrounding the shaft P² between said gear wheel and the collar P
as shewn in Fig. 2.
The escapement wheel P³ has formed upon its front face a series of radiating
grooves or notches a¹ with which the escapement dogs and t¹ alternately engage as
the bar R is moved to and fro horizontally by the action of the lever R¹ thereon-to
which said bar R is pivotted at one end-its opposite end being supported and guided
in the movement by the shaft P2 which passes through a slot in the wider part of said
bar as before described.
The dog is firmly bolted to the bar R and has its inner end shaped and arranged
to enter and fill a groove a¹ in the escapement wheel P³ when the bar R is moved to
the right.
The bar R also has firmly bolted thereto upon the opposite side of the escapement
wheel P³ from the dog t-the stand in the inner end of which is mounted the short
horizontal shaft carrying at its inner end the dog t¹, and upon its outer or front
end the arm, as shewn in Fig. 7-19, 32 and 33.
The dog has formed upon the rear side of its movable end the tooth e² which
engages with and fills a groove a¹ in the escapement wheel P³ as the bar R is moved
to the left.
The stand 3 has set in its front side near its upper edge the stop pin o³ so arranged
as to engage with the free end of the arm b' to limit the upward movement of said
arm and the dog t¹ when the dog is moved out of engagement with the groove a¹
in the escapement wheel P³ and said wheel is moved about its axis by the action of
the spring on the shaft t upon the drum and the cord /*.
When the bar R is moved to the right the dogt engages with a groove in the
escapement to lock it and the dog t' is disengaged therefrom by the same movement
and the instant that the tooth of said dog is free from the escapement wheel
the free end of said dog and the arm & drop until the descent is arrested by the

page_text: arm 65 coming in contact with the stop bar d' mounted by means of the screw d² and
a slot in the said bar upon the broad plate like inner end of the rod 3 the outer
end of which is pivoted to the lower end of the lever R¹ and its inner end has a
bearing upon the screw stud d which passes through the slot et, formed in said plate
like inner end, and screws into the stand 3 as shewn in Figs. 7. and 19.
The stop d¹ is held in a position with its left hand end projecting beyond the end of
the upper portion of the plate like portion of the rod by the spring d³ and is
located in such a position below the arm 65 that the dog t¹ will drop a distance just
equal to the distance between the centers of two grooves a² which distance must be
just sufficient to permit the carriage and paper carrying roll to move end wise a
distance equal to the desired space feed.
It will be seen upon inspection of Fig. 7 that the rod d³ is pivoted to the lever R¹
at a greater distance from the fulcrum of said lever than the bar R and as a con-
sequence said rod 3 moves a greater distance than the bar R, when said lever R¹ is
vibrated, and it will also be observed that the lever R' is vibrated, a uniform distance
by every movement of a type key, which distance is just sufficient to operate the
escapement and permit a movement of the paper carrying roll equal to the desired
distance between two letters in the same word.
To insure uniformity in the letter spacing the stop d must project to the left of the
end of the upper portion of the plate like part of the rod d³ a sufficient distance to
be in a position to intercept the downward movement of the arm 6, when the lower
end of the lever R' is at the extreme of its movement towards the right hand when
operated by the letter key.
It is well known that at the end of each word the paper carrying rolls of the type
writing machines must have an extra movement imparted thereto before commencing
another word in order to properly separate the words, and that this is accomplished
by an extra key which is arranged to operate the space feed mechanism without
operating a type bar, the operating of which key occupies the same amount of time
that is required to print a letter, and as the words in ordinary composition will
average only about six letters in length it follows that if the extra time employed in
operating the space key for spacing the words can be saved, a gain of one seventh of
the time required to do a given job will be made.
To accomplish this desirable result the escapement wheel and dogs, are so con-
structed and the levers by which said dogs are operated are so connected with the
type bar operating keys, and the word space keys that said levers and escapement
dogs may be moved a greater distance by the word space key, than they can by the
type bar operating key.
This is accomplished by the peculiar construction of the escapement wheel and
dogs and the fact that the levers J, J, are not connected to the spindle J², but act
upon its lower end to lift it, and present no obstruction to a greater lift of said
spindle by the action thereon of the word space key whenever desired.
To obtain the saving above referred to, it is only necessary to arrange the word
space key so that it can be struck at the same time that the type key for printing the
last letter in the word is struck.
To this end a series of word space keys or levers L, are arranged around the upper
end of the spindle J, so as to radiate therefrom with their inner ends in position to
engage with the head or collar k³ of said spindle and provide at their outer ends with
a segmental plate or pad arranged in near proximity to the circularly arranged series of
letter keys so that whenever either one of said letter keys is depressed by the operators
finger, one of said word space keys L may be depressed at the same instant by
another finger the consequence of which will be that the lever R' will have its lower
end moved towards the right a greater distance than when acted upon only by
depressing the letter key and the stop will be moved to the right a sufficiently
greater distance than the arm b' to remove it from beneath said arm and thus permit
the free end of said arm to fall till it is arrested by the projecting lug e on the inner end
of the rod d³ and the dog is in a position for its tooth c² to engage with the second
a of the wheel P³ from the groove with which it was last in engagement
groove

page_text: when said dog is again moved towards the left and thus rendering it possible
for the spring acting through the drum t and cord t to move the carriages B and C
and the paper carrying roll a distance towards the left equal to twice the distance
it is moved when only the letter key is operated.
To one of the stands E is secured the casing or frame N2 of a registering mechanism
consisting of the worm of the worm wheel of provided with the pin and the toothed
wheel of and the stationary index fingers o8 and 0° the wheel of having on its front
face a scale graduated from 1 to 1000 and the wheel o' having a similar scale
graduated from 1 to 10.
The worm shaft of has secured upon its rear end the ratchet wheel o¹0 to which an
intermittent rotary motion is imparted by the action of the pawl o" pivotted in a slot
in the bar o mounted in bearings in the stand o¹³ as shewn in Figures 7, 9, 21
and 37.
The bar o is provided at its outer end with a head or shoulder to limit its inward
movement and has fitted thereto the spring the tension of which serves to move
said bar inward or to keep its head or shoulder in contact with its outer bearing as
shewn in Fig 7.
The bar is located in the same vertical plane as that in which the lever R
vibrates and the normal position of its inner end is such that the lever R' will not
strike said bar when only a letter key is depressed, but when either of the word space
keys is depressed said bar and its pawl will be moved outward so as to turn the ratchet
wheel o¹ and the worm shaft of about their axis a distance equal to one or more of the
teeth on said wheel.
A stop pawl n is pivoted to the stand o¹³, and engages with the teeth of the
wheel to prevent it being turned backward when the bar o2 is moved inward by
the action of the spring n.
The word space keys may be arranged with their segmental pads inside the circular
series of type keys as shown or said segmental pads may be outside of said type keys
if desired without affecting the principles of the invention.
To insure the falling of the free end of the dog t¹ when it is disengaged from
the escapement wheel-a spring presses upon its upper side as shown in Figure 19.
The carriage B has secured thereon the detent spring * constructed and arranged
to engage with a notch formed in one of the bars e of the carriage C for the purpose
of connecting said carriage B and C so that they will be moved together when force
is applied to the lower carriage B while at the same time the upper carriage C may be
moved independently of the lower carriage.
To the under side of the carriage B at t is secured one end of a cord to preferably
of catgut the opposite end of which is secured to and wound upon the periphery of the
spirally grooved drum t firmly secured upon the inner end of the shaft t' mounted
in bearings in one of the ribs A¹ of the base A, and in the toothed hub S fitted to
revolve in the outer end of the fixed sleeve or casing S' secured to the base plate A,
said shaft having wound thereon, within the casing S¹ the special spring to
the inner end of which is made fast to the shaft which it operates, every
time the escapement releases a tooth of the escapement wheel, to move the
carriage B and C, and the paper roll D, from the right towards the left a letter space,
or the distance from one letter to the next, or a space between two words.
When the paper roll has been fed a distance equal to the length of the line being
printed and the carriages are drawn back to commence a new line the unwinding of
the cord from the drum 8 winds up, or sets the spring to again ready to feed the
carriages and paper roll for printing another line, the toothed hub S being prevented
from revolving with the shaft t' by the spring stop-pawl u secured to the bed plate A
as shown in Figure 26.
T. Figures 1 and 2 is a bell upon which the hammer strikes when the end of a
line is reached.
ย
The hammer is secured upon one end of the shaft U mounted in bearings U₁ U
cast upon the base-plate A, and has wound upon its opposite end the tortional spiral
spring v as shown in Figure 17.

page_text: The portion of the shaft U between its bearings has formed therein a longitudinal
groove and has adjustably secured thereon by means of the thumb screw³ the
point of which enters said groove 2, the block U upon the upper side of which is
formed the cam or wedge surface with which the lower end of the arm V pivotted
to the carriage B engages to turn the shaft U, and raise the hammer
the tension of the spring which when the arm V has passed the cam surface p
causes the hammer to strike the bell T as a signal to the operator.
against
The arm V is prevented from moving about its axis when acting upon the cam
surface to raise the hammer by the stop pin w against which it is held by the tension
of the spring a connecting said arm to the pin 2 but when the carriage B is moved
back after the bell has been struck the arm V strikes against the end of the cam »
and is moved about its axis until it can pass over the top of the cam when the tension
of the spring w³ causes it to assume its normal position as shown in Figure 17,
In the under side of the carriage B is set the downwardly projecting pin w³ which
engages with the pin set in, and projecting horizontally from, the rib A¹ of the
base A for the purpose of limiting the movement of the carriage B in that direction.
The toothed hub S is provided with two holes in its outer face to receive the pins of
a forked key for turning said hub to adjust the tension of the spring to as shown in
Figure 26.
W is a stand secured to the base plate A in front of the carriages B and C and
having pivotted to its upper end the index finger W₁ provided with a laterally
projecting stop pin which engages with the stand W to limit the movement of said
finger about its axis of motion in either direction.
The index finger W₁ is designed to be kept folded by the side of the stand W as
shown in Figure 2, except when used to register the position of the carriage when it
is desired to correct an error in the printing.
The construction and position of the stand W and finger W' is such that the end of
the fingers when turned up into the position shown in Figures 21 and 22, will mark
the exact spot where the next type hammer will strike upon the paper.
If upon examining the matter printed the operator finds that an error has been
made by printing a wrong letter or mis-spelling a word he turns the finger Winto
the position shown in Figure 22, and moves the two carriages together endwise upon
the bed till the defective letter or word is under the point of said finger, and then
draws out the carriage C to the left till the defective place is exposed when he crases the
letter or word as the case may be and returns the carriage to its normal position on
the carriage B, turns down the finger W, lowers the head of the machine to its
normal position, (said head having previously been raised to permit the movement of
the finger W¹) and prints the correct letter or word.
The paper carrying roll D mounted in bearings C, C, of the carriage C has
secured upon each end of its shaft outside of said bearings the milled head C² for use
in moving said roll and carriage endwise by hand, and rotating said roll when putting
in or taking out the paper.
The shaft of said roll also has firmly secured thereon first inside each bearing C', C',
a ratchet wheel C³, and between said ratchet wheel and the end of the roll has loosely
fitted thereto a short sleeve or thimble a² firmly secured to one end of the rod a³, the
opposite end of which has a bearing in the slotted arm D₁ which embraces said
thimble and has secured to its front end the bar D2 to which is secured the upper
edge of the curved sheet-metal guide-plate D* the purpose of which is to facilitate the
insertion of the paper between the bar D2 and the roll D.
Each arm D has formed thereon an outwardly projecting lug or dog at the inner
face of which is beveled to fit the inclined faces of the teeth of the ratchet wheel C³
with which it engages and upon which it acts as a pawl to move the roll D, about its
axis a distance corresponding to the desired distance between the lines of printing, a
spring a surrounding the rod a³ between one end of the slot in the arm D' and the
thimble a serving to hold said dog in engagement with the teeth of the ratchet wheel C³,
and permit a slight outward movement of said dogs, with the arms D' and bar D²
B

page_text: whenever the bar D² is depressed so that said dogs may pass to, and engage with, the
next tooth of the ratchet wheel C³.
A spiral spring 66 is connected by one end to the rear end of each of the arms D¹
and by its other end to the carriage C, said springs serving to move the arms D'about
the axis of the roll D, in one direction, and maintain the bar D² in its elevated position
until depressed by the operator, by pressing his thumb or finger upon the pad 7 of the
bent arm D³ secured by its opposite end to the under side of the arm D' as shown in
Figure 12.
;
The front edges of the end pieces or bearings C, C, are provided each with two
shoulders and ct the portions of said bearing or end pieces between said shoulders
being made concentric with the axis of the roll and the arms D³ extend across the front
edge of said end pieces between said shoulders and in close proximity to said concentric
surface as shown in Figures 11 and 12.
The distance between the shoulders 3 and is equal to twice the distance apart of
the lines of printing plus the width of the arms D³ wherethey pass said end pieces ("C'.
In order to adapt this mechanism to feed the paper in the direction of the circumfer-
ence of the roll D a distance equal to the desired distance between two lines of printing
or twice that distance a movable stop d is pivotted to the outer faces of the end bearing
pieces (C¹, said stop d' hanging pendent from its pivotal axis with its lower end a
distance of a line space below the shoulder c³ and in position to intercept the upward
movement of the arm D³ as shown in Figure 11.
When it is desired to feed the paper a distance equal to two line spaces, the pendant
stop is turned upward till it rests against the pin d', when the tension of the springs 66, 66,
will cause the bar D2 to move upward, moving the roll D about its axis till the upper
edge of the arm D³ strikes the stop c³.
When a line has been completed, and the operator desires to move the paper roll so
as to place it in position for commencing a new line, he places a finger of his left hand
against the end of the carriage B and his thumb upon the pad 67 of the arm D³ he
presses downward with the thumb till the lower edge of the arm D³ strikes the
shoulder e thus causing the dog a¹ to engage with a new tooth of the ratchet wheel C³
and at the same time he moves the carriages B and C and the roll D to the right by
pressing upon the carriage B.
When he removes the pressure from the pad of the arm D³ the springs 6º, 6º,
reacting upon the arms D₁ will cause the arms D¹ and D3 D³ to be moved upward till
the arms D³ come in contact with the pendent stop d or the shoulder e according
as to whether it is desired to feed the paper one or two line spaces.
A spring stop pawl d is secured at one end to one of the end pieces C¹ in position
to engage by its shoulder with the teeth of the ratchet wheel C³, the free end of said
pawl extending beyond its shoulders to a point beneath the arin D3 with its upper
surface on a level with the outer corner of the shoulder c as shown in Figure 12.
Whenever from any cause it is desired to turn the paper roll backward, the operator
presses down upon the pad and at the same time presses slightly forward thereon
until the arm D³ passes the shoulder c¹, and striking the spring pawl near its free end
disengages the shoulder of said pawl from the teeth of the ratchet wheel C³ the spring a
yielding sufficiently to permit the requisite forward movement of the arms D' upon the
thimble a² to allow the arm D³ to pass below the shoulder c' and release the dogs a
from engagement with the ratchet wheel C³.
Just under the milled head 02 and between it and the bearing upon each end of
the shaft of the roll D is mounted a disc de provided with the curved slot e and the
outwardly projecting arm e, the outer end of said arms e being connected together
by the rod e as shown in Figures 1, 11, 12 and 13.
A pin e set in each of the bearing end pieces (projects into the curved slots e in
the disc to serve as a stop to limit the movement of the rod about the roll D in
either direction.
The object of the rod e' is to hold down the rear portion of the paper which is
passed beneath it.

page_text: When it is desired to introduce a sheet of paper into the machine preparatory to
printing thereon, the rod e' is moved about the roll D from the position shown in
Figure 11, to a position in close proximity to the bar D². The sheet of paper is passed
between the roll D and the curved guide plate D4, from the rear, until it enters the bight
between the roll D and the springs D D³, secured upon the carriage Cand projecting
upward through the guide plate D and between the roll D, and the bar D² when the
roll D is rotated in the direction indicated by the arrow on Figure 13.
When the paper has reached the desired point, the rod e' is moved back into the
position shown in Figure 11.
In each of the brackets G see Figures 3 and 4 is fitted a set screw e to serve as an
adjustable stop to limit the upward movement of the type bar H.
It will be observed by reference to Figure 7 that the plate of the carriage B extends
beyond the ribs c and d and has set in its upper side the headed pin B' and by reference to
Figure 14 that the carriage C'is provided at the opposite end and its under side with the
lipped socket B2 open upon its inner side which engages with the head of the pin B¹ when
the carriage C is drawn toward the left hand to the limit of its movement in that
direction when the carriage C may be moved about the pin B' as a pivot into a position
at right angles or nearly so to the carriage B the object of which is to render the placing
of the paper upon the roll more convenient than with said carriage C in its normal
position upon the carriage B.
If for any purpose it is desired to remove the carriage Centirely from the
carriage B after it has been brought into engagement with the pin B¹ and turned at
right angles or nearly so to the carriage B the operator has only to move the carriage
slightly to the rear to disengage the sockets B from the pin Br.
