IMPROVEMENTS IN TYPE WRITERS
Year: 1884

page_text: "
I ALFRED JULIUS BOULT of 323 High Holborn in the county of Middlesex,
Engineer, do hereby declare the nature of this invention for IMPROVEMENTS IN
TYPE WRITERS (a communication from Charles Spiro of New York, United
States of America, Manufacturer), and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :-
This invention belongs to that class of type writer which employ a sliding paper
carriage and a rotary type-wheel mounted over the carriage and having types on
its periphery which is revolved by hand to bring the desired type into position and
then depressed against the paper to print the selected lotter.
In this improvement the type-wheel is mounted on the end of a depressible lever
and the wheel is provided with a central or axial twirling handle, and the carriage
is provided with a feed rack with which a feed-pawl engages, which pawl is
worked by the reciprocation of the depressible lover to advance the carriage a step
after each letter is printed. This feed-pawl works in relation with variable feed-
stops on the rim of the type-wheel, which vary in accordance with the width of the
types or letters whereby the feed impulses are varied in length to correspond with the
varying width of the letters printed and a perfect feeding or spacing action thereby
secured. My present invention therefore lies partly in the features above outlined
and partly in an improved inking devico, also in index devices to indicate the
movement of the type-wheel and the printing position of the types, and in the
special construction of parts of the paper carriage and in other details, as hereinafter
fully set forth and claimed.
In the drawings annexed Fig. 1 presents a longitudinal front elevation of this
improved type-writer, and Fig. 2 presents a plan view thereof. Fig. 3 is a
longitudinal rear elevation with the type-writer in its raised or quiescent position,
while Fig. 4 is a similar view with the wheel depressed in the printing position.
Fig. 5 is a front end clevation and Fig. 6 is a similar view with the type-wheel and
its twirling handle removed. Fig. 7 is a fragmentary rear elevation showing the
feed and spring mechanism. Fig. 8 is a sectional detail of the type-wheel and its
attachmenta

page_text: In the original drawings my machine is represented of full size, and referring
first to Figs. 1 and 2, a indicates the base of the machine which is made in the
forin of an oblong casting formed with short feet a¹ on the bottom on which the
machine rests. On the top of the base is formed a longitudinal dovetailed way c
which extends the entire length of the base, as shown in Fig. 2, and in which is
fitted the framio d of the paper-carriage de f, which is capable of sliding freely in
the way lengthwise of the machine, as will be readily understood from the
drawings. In bearings at each end of the carriage-frame d is mounted the paper-
roller e, and the bearings are connected together by, a ratchet-bar or rack f which
extends longitudinally parallel with the surface of the roller e and close to the top
of the same on one side of the carriage, as fully shown in Figs. 1, 2, 3, 4 and 5.
The rear end of the paper-roller e is fitted with a small smooth pintle or journal g'
which is received in a hole in the rear bearing d¹ of the carriage-frame, while the
front end of the roller is provided with a threaded shank g, as shown in Fig. 4,
which is a loose fit for a large, bearing-socket or hole 6 of the carriage, as fully
shown in Figs. and 6, which bearing is slotted at the top, as seen in Fig. 6, to
allow the threaded shank g to be lifted up and thus permit the removal of tho
roller from the carriage, às will be readily understood. The operating knob h of
the roller e, however, has around 'shank h¹ which nicely fits the bearing socket b
and screws onto the thread shank g, as shown in Fig. 4 and in dotted lines in Fig. 5,
Hence when the roller is placed in its bearings and the operating knob h screwed
in place, as shown in Figs. 4 and 5, the roller is hold against displacement yet is
free to revolve, whoreas when the, knob is unscrewed as shown in Fig. 6, the
roller can be lifted out or replaced, as will be readily comprehended. Two thin
broad springs ii are fixed at one end to the base of the carriage and pass under
and partly around the roller on one side, pressing lightly against the roller, as fully
shown in Figs. 1, 2, 5 and 6. The paper sheet x, as shown in Fig. 5, on which the
printing is to be done is passed in under 'the roller between the surface of the samė
and the springs i, and is thus curved around the roller under the springs and over
the top of the roller and out under the rack-bar f, and finally passes under a littlo
pressure or guide-roller ; which is mounted in a spring bearing k fixed to and
depending from the outer sido of the bar, as shown best in Figs. 3, 4, 5 and 6. The
roller has a deeply concaved periphery so that only its narrow flanged ends boar
upon the paper and thus prevents sinearing of the ink and ensures a better guiding
nction, while the spring & keeps the roller constantly pressed against the paper to hold
it evenly and firmly on the paper-roller e. By turning the knob h the paper-roller
will be turned to advance or feed the paper for the successive lines to be printed,
as will be readily understood, and in order to provide a regular space for this line
feed the knob is formed with a notched rim 3 which is engaged by a click spring 4,
ns best shown in Figs. 2, 5 and 6. Hence when the knob is turned to adjust the
paper to the desired line the click 4 will fall into one of the notches and thus hold
the roller and its superposed paper in that position, and when it is desired to
advance the paper for the next lino the knob is turned one notch further when tho
click will spring out of the last notch and spring into the next and thus allow the
roller to be revolved in the desired successive steps and yet always hold it at each
step. The threads on the shank h' of the knob h are such as cause the knob to
tighten in the direction in which it is revolved to feed the paper, and henco.the
knob has no tendency to unscrew in the direction in which the roller is turned to
feed the paper.
The above described details of the carriage add greatly to convenience and
efficiency in the operation of the machine, and are at the same time simple and
inexpensive in construction, as will bo readily appreciated.
The paper carriago and its adjuncts having been now set forth we will refer to
the type-wheel and its adjuncts, which are mounted above the carriage on the top
of the fixed frame or standard 7, which arises from one side of the base and over-
bangs the paper carriage, as shown well in Figs. 1, 2, 5 and 6. The side of the

page_text: frame is lightened by a lower open scroll-work panel, and by an upper open
panel through which the printing on the paper-roller can be easily read.
and
The type-wheel m is placed, as shown, centrally over the paper-carriage,
revolves in a plane at right angles to the longitudinal movement of the carriage.
This type-wheel is mounted on the end of a depressible rod or lever n, which is
pivoted at the fulcrum end to a lug 5 on the top of the frame l, and the opposite end
of the lever near the type-wheel is guided vertically between a forked guide o
which rises from the narrow nose or beak o¹ of the frame which closely overhangs
the paper-carriage and projects up close to tho type-wheel. A spring 7 betweon the
top of the frame and the depressible lever n tends constantly to raise up the lever
and keep the type-wheel elevated above the paper, as shown best in Figs. 1, 3 and 5,
the up-motion of the lever being limited by the stop-pin 8 on the forked guide o,
while the down motion is limited by the adjustable stop-screw 2.
The type-wheel mi is free to revolve on the end of the lever n, and is provided
with a central twirling handle m¹ which may be revolved or twirled between the
fingers to bring any desired type to the underside of the wheel to the printing
position, after which the handle is depressed to force the wheel down on the paper
on the paper-roller to impress the desired type thereon, as indicated in Figs. 4
and G.
The type-wheel is formed of a disk of hard metal having slots cut in its periphery,
in which are inserted the types m², which usually include the alphabetic letters.
with the numerals and points of punctuation, and this type-wheel is fixed at the
back to a toothed locking wheel p which revolves with the type-wheel on the end
of the lever n (see Fig. 8,) and its periphery is provided with tooth corresponding
in number to the types on the type-wheel.
On the front of the beak 6 of the framo la tooth q projects forward in the path
through which the locking-wheel p moves when the lever is depressed, which tooth
will therefore fit between two of the teeth in the locking wheel when the type-
wheel is depressed, as indicated in Figs. 4 and 6, thus locking the wheels against
rotation when the selected type is being printed, and thereby ensuring a good
impression of the desired letter.
Behind the hub of the locking-wheel p a pendulous arm r is hung on the lover n
so as to swing freely thereon, which arm normally hangs down straight, as shown
in Figs. 1, 3 and 5, and on the tip of this arm just below the periphery of the
type-wheel is mounted an inking disk or roller & disposed proferably in a horizontal
plane and contacting near its periphery with the typed rim of the type-wheel, as
fully shown in Figs. 1, 3 and 5. This inking roller is preferably made of a thin
metal disk having a central hub which turns freely on the end of the pendulous
arm, and faced on the top with a disk of felt which is saturated with the ink and
contacts with the rim of the type-wheel, as illustrated. The pendulous arm T
has a short forked crank-arm projecting at right angles from its pivoted end and
engaging a fixed pin on the forked guide o, as shown in Fig. 1 and in dotted
linos in Figs. 5 and 6. It will now be seen by referring to Figs. 1, 3 and 5, that
the pendulous arm and its inking-roller s normally gravitate and assume a vertical
position with the inking-roller contacting with the type-wheel at its printing point
on the underside and just over the paper-carriage.
It will therefore be scen that when the type-wheel is revolved back or forth to
bring the desired type to its printing position that the ink-roller will be revolved
over the successive types and the surfaces thereof will become nicely inked
preparatory to the impression. As soon, however, as the desired type is brought
to the printing position and the wheel then depressed to print the same the
depressing motion of the wheel will cause the pendulous arm and its ink-roller to
he swung to one side revolving slightly around the axis of the type-wheel, as
shown in Fig. 6, thus removing the inking roller out of the way from the printing
position of the wheel above the paper carriage and thus permitting the selected
type to descend upon the carriage, as fully shown in Fig. 6. As soon as the wheel
is allowed to risu after the impression the inking arm and rolls are

page_text: back to the vertical position, as shown in Fig. 5. It will be therefore seen that
this inking device is very simple and effective and is very neat and compact in its
construction, and while the inking roller is kept normally in contact with the
printing point of the wheel it is automatically swung out of the way when the
desired type is printed yet is kept in continual contact with the rim of the wheel,
and a uniform and thorough inking of the types is thereby secured.
"
The manner in which the type-wheel and its adjuncts are mounted on the end
of the depressible lever n is fully shown in Fig. 8. The end of the lever n is
reduced to form a tonon or journal n¹, and the inking arm is first set on this
journal up against the washer. This locking wheel is formed with a long sleeve or
hub pl which extends over the journal to the end thereof and is free to turn
thereon, and in the end of tho journal is screwed a small-headed stud p² which
holds all the said parts in position, as will be readily understood. The type-wheel m
is next slipped over the hub of the locking-wheel p and fitted up close to the
locking wheel, a pin 23 on the locking-wheel engaging with a hole in the type-
wheel, as shown in Figs. 8 and 5, so as to rotatively engage the two together.
The twirling bandle m¹ of the type-wheel which is preferably made of hard
rubber is finally screwed over the sleeve of the locking wheel close up against
the type-wheel and the parts are thus held in position and made ready for
operation and a nice finish is imparted to the construction, as will be readily
appreciated.
Referring to Figs. 1, 3, 4, 5 and 6, t indicates a toothed index-wheel which gears
with the locking wheel p in a plane at about right angles thereto. This wheol is
mounted to turn on a central pin in a frame or bracket 12 having a hub 13 at the
base which is fastened on the depressible lever n by a clamping screw or other
fastening just back of the forked guide o, as well shown in Figs. 3 and 4. On
the bracket 12 is fixed a dial or index-plate 14 which covers the index-wheel t,
and around the periphery of the dial is marked the different characters which the
type-wheel carries, while an index finger 15, attached to the axis of the index-
wheel projects over the surface of the dial, as well illustrated in Figs. 1, 2 and 6.
The parts described are of course so arranged that when any particular type on the
type-wheel is at the printing point at the bottom of the wheel the index finger 15
will point to the corresponding character on the dial, as will be readily understood.
Hence by this means the operator is enabled to rapidly twirl the type-wheel to or
fro to bring the desired letter to the printing position and the index finger will
clearly show the position in which it may be found and the position at which the
wheel is to be depressed to print the desired letter, thus enabling the operator to
perform quick and accurate work after a short experience. The bracket 12 may
be adjusted around on the lover 7 so as to present the face of the dial at different
inclinations to the operator and thus enable him to adjust the dial to the best and
most convenient reading angle according to individual desires, as will be readily
appreciated.
A light click spring 16 is fixed to the bracket 12 beneath the index-wheel t, and
the pointed tip of the spring falls between the teeth of the index wheel as the same
is rovolved, and will thus serve to readily indicate when the wheels are turned to
the desired letter and will prevent the inadvertent turning of the wheels after the
letter is selected and during the depressing motion to print the letter, as will be
readily understood.
The feed mechanism whereby the paper carriage is advanced one step after each
letter is printed, and these steps varied in length according to the width of the
letter to be printed, will be now described.
Referring first to Figs. 1 and 2 it will be seen that the types are arranged on
the periphery of the type-wheel with the left-hand side or edge of all the characters
in line with each other, the feed-motion of the carriage being also to the left, as
indicated in Fig. 1. Now on the periphery of the type-wheel, as best shown in
Fig. 5, a recess 17 is formed between each type, and each recess represents a
particular character and varios in depth according to the varying width of thỏ

page_text: characters, the widest letters, such as M and W, having the deepest recesses, ns.
indicated by the two deep and somewhat oblique recesses shown in Fig. 5, while
the narrowest characters, such as I, are represented by the shallowest recesses, as
will be readily understood.
Referring now to the rear side of the machine, shown in Figs. 3 and 4,
indicates an elbow-lever pivoted on the front end of the frame with its long
arm projecting horizontally behind the lever n and terminated with a depressing
finger knob u for manual operation when required, while the short arm hangs
vertically and is bent to overhang the ratchet-rack f of the paper carriage, and is
terminated with a tooth u² which normally engages with the back of one of the
rack-teeth and thus prevents the carriage from moving backwards in its guides.
The long or upper arm of the elbow-lever u is normally raised by a spring 18 so as
to keep the tooth u in contact with tho rack f and press the lover against a pin 19
which projects from the lever n and bears upon the elbow-lever u, as fully shown
in Figs. 2, 3 and 4. The spring 18 is formed from the same sheet of steel as the
spring 7 by simply slitting the sheet and thus forming two spring tongues which
simultaneously tend to keep the depressed lever n and its type-wheel and also the
elbow-lever u all raised into their normal positions, shown best in Fig. 3 and partly
in Figs. 1 and 5.
Now referring again to Fig. 3 it will be noted that on the lower arm of the
elbow-lover ua pawl-lever vis pivoted having one arm reduced to a pawl point to
engage the teeth of the carriage-rack f, while the opposite arm or "tail" of tho
pawl projects horizontally above the rack towards the rim of the type-wheel and
in line with one or other of the recesses therein (see Figs. 5, 2 and 3,) the end of
the tail being tapered to a narrow wedging point so as to readily enter said
recesses, as fully shown in Fig. 3. The spring v¹ of the pawl v tends constantly to
keep the point of the pawl in engagement with the rack f, and to press the long
tapering tail of the pawl against a stop-pin w' which projects from one arm of a
secondary elbow-lever w pivoted behind the lever u and having its upper arm
forked to engage the pin 19 on the main lever n.
It may now be easily seen by referring to Fig. 4 that when the lever n and its
type-wheel is depressed to print the desired letter that the pin 19 will sway the
elbow-lever u in the position shown and thus move the pawl v back over the teeth
of the rack and bring the tapering tail of the pawl into one of the recesses on
the type-wheel, the parts being so arranged that the recess which the tail of
the pawi will enter will correspond to the letter being printod, as will be readily
understood. It will now be understood by referring to Figs. 3 and 4, that
during the depressing motion of the type-wheel and the back movement of the
pawl on the rack f, as just described, that the point of the pawl will remain
pressed against the inclines of the rack-teeth, and will slip back over the same
until the tail of the pawl has made contact with the bottom of the recess in the
type-wheel when the point of the pawl will then be lifted out of the teeth and
will move the remainder of the stroke idly above the rack, as shown in Fig. 4.
Now it will be obvious that the deeper the recess in the wheel is the later will
the pawl be lifted out of the rack and the greater the number of teeth over which
it will slip, and vice versa. It will be also readily understood that as soon as the
type-wheel is allowed to rise after making the impression, that the pawl will move
back and will fall into the tooth out of which it was previously raised, and the
back motion of the pawl being now continued while engaged with the rack it will
now impart a feed motion to the carriage equal to the number of teeth over which
the pawl slipped during the previous motion towards the type-wheel. Hence the
depth of the recesses in the type-wheel determines the number of teeth over which
the pawl will idly slip at the forward motion and therefore tho amount of .feed-
motion which will be imparted to the paper-carriage at the back or feeding move-
nent of the pawl, so that by this means the carriage will always be fed onward a
step equal to the width of the letter last printod. Thus if the widest letter is
equal to four teeth on the rack f, and the narrowest is equal to one tooth, then the.

page_text: feed motions of the pawl will vary from one to four teeth in accordance with the
varying depth of the recesses in the. type-wheel representing the letters, thus
producing a perfect and efficient feed-motion which regulates the feod of the paper
automatically according to the width of the characters printed, which is a very
desirable feature as it saves space on the sheet and greatly improves the appearance
of the printing and renders it much more readable.
Referring to Fig. 3 it will be seen that when the type-wheel and feed devices
rise or return to their normal positions, as illustrated in this figure, that the fixed
tooth u³ on the pawl-lever will engage.the rack f in one direction against forward
motion while the pawl v will engage it in the other direction against back motion,
thus locking the carriage in the position into which it was last fed and thereby
preventing the momentum of the forward feed impulse from moving the carriage
too far and also preventing any displacement during the movements to selection of
the next character for printing.
Now in order to feed the carriage forward to provide spaces between words or
sentences the knob u may be depressed, in which case by referring to Fig. 7, it
will be seen that the pawl-lever u will be swayed independently of the main or
type-wheel lever n, and also independently of the stop-lever w, which levers n. w.
will remain at rest as shown. Hence the tooth u will not only be raised out of
the rack but the pawl v will also be slipped back its full distance, say of four
teeth, at which fourth tooth the tail of the pawl will be forced against the stop-
pin w¹ in the now stationary stop-lever wand thus be lifted out of the rack, as
shown in Fig. 7. When therefore the knob u¹ is again released the described parts
will return to their normal positions and the point of the pawl v in entering the
tooth which it previously left and in pressing forward against the same will thus
move the carriage forward the space of four teeth and thus provide the necessary
feed space between letters or words. By depressing the knob u two or more
times this space will of course be correspondingly increased as may be desired.
It will be noted from what has been already described and shown in Fig. 7, that
the function of the lever wand its pin w¹ comes into action only when the knob is
depressed for the spacing feed, the lover and pin thon affording a fixed stop to
cause the pawl to be lifted out of the rack f, as described. At all other times
when the type-wheel and levor n are moved up and down and the regular automatic
feed movements produced, the stop-lever w and pin w' move with the lever u and
pawl v, and hence cannot affect the pawl v, and in fact, perform no function as the
engaging and disengaging movements of the pawl aro in this case determined
entirely by the recesses in the type-wheel and not by the pin w', as will be readily
comprehended.
It may be further noted that when the knob u is fully depressed, as shown in
Fig. 7, the feed-rack will be entirely freed from the feeding devices u² and v, and
hence the carriage may be slid entirely out of the base or shifted forward or
backward to any desired position so that a line may be commenced on any part of
the sheet desired.
By referring again to Fig. 7 it may be observed that when the knob u! is fully
depressed to produce the spacing feed shown, that the tail of the pawl v will not
enter any of the recesses in the type-wheel at all, nor will it closely approach tho
rim of the wheel for the reason that as the type-wheel is not itself depressed the
vertical movement of the tail of the pawl will not be sufficient to bring it close to
the rim of the type-wheel, as will be readily comprehended from Figs. 5 and 7.
It may now be seen that these feeding devices while neat, compact and simple
are very efficient in action, and not only provide an automatic variable feed in
accordance with the width of the character printed, but also provide a simple
manual spacing feed, as well as means for freeing the carriage to shift it to any
position required.
Tho invention is not limited to having the variable feed stops on the type-wheel
in the form of circumferential recesses-between the types as the stops may be made

page_text: in any other form and be placed on the side of the wheel provided they are integral
with the type-wheel, which is novel in this machine.
Now in order that the carriage may be slid back at the end of each line to the
same position at which the line was commenced so as to preserve a uniform margin
in the printing, the front edge of the base is graduated with a series of numbers, as
shown best in Fig. 2, and an index point or finger y projects from the middle of
the carriage out over the graduated edge of the base, said finger being shown in
dotted lines in Figs. 1, 5 and 6. Hence by starting the carriage with the index
finger at one of the numbers according to the width of the margin desired, and
always bringing the carriage back to the sauno number in commencing the next
line a uniform margin will be preserved. A series of holes are preferably bored in
the edge of the base adjoining the graduated numbers, as shown, in any one of
which may be fitted a stop-pin 33, the distance of the pin from the first hole
determining the width of margin, as will be readily understood, and it will be seen
that when the carriage is slid back to commence the next line the finger y will
strike against the pin and thus determine automatically the point at which to
commence each line, which will be a great convenience to the operator.
It may now be appreciated that this invention presents a novel form of type-
writer which possesses many advantages; firstly, in its neatness and compactness
of form as the size of the machine is comparatively small, the original drawings
represent the machine in its full size; secondly, its comparative simplicity and
cheapness and the fact that it may therefore be furnished at a low price; thirdly,
its perfection in all the operations necessary for a type-writer and the fact that
very perfect work may be performed thereon owing. to the accurate feeding and
inking devices; fourthly its method of manipulation is simple and sufficient speed
of work is easily acquired after experience therewith.
