page_text: I, GEORGE WASHington Baldrige, residing in the City of Saint Louis, State of
Missouri, United States of America, Stenographer, do hereby declare the nature of
this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
My improvements relate to type writing and matrix machines.
In the present machine the keys of the key board are respectively connected
with what may be termed type-bars bearing types. When the keys are at rest the
types bear upon an inked surface, and when the keys are moved they act to move
the type-bars and thereby lift the types, which have been inked by coming in
contact with the inked surface, and transfer them into position for being impressed
upon the paper it is desired to write upon. The keys are successively operated,
and the types are successively brought into the same position, then impressed upon
the paper, and then withdrawn into their original positions. The force used to
impress the types after they have been moved into position for printing, is derived
preferably from an electric current, to which end a magnet is located in the vicinity
of the point where the printing is done, and the magnet-armature is provided with
an arm which, when the circuit is closed, is moved against the type-bar, causing
the type of the bar to be impressed upon the paper. The electric current is closed
and opened by the key, the key in its movement operating first to shift the type
from the inked surface into position for printing and then to close the circuit and
effect the printing, after which, on releasing the key, the circuit is opened and the
type lifted and withdrawn into its place upon the inked surface. Meanwhile the
paper-holding mechanism is suitably operated to enable the paper, as to spacing
and lining, to be printed in the ordinary manner. The distinguishing feature of
the type-bars is their elasticity, which enables the type end of the bar to be sprung
so as to bring the type against the surface being printed upon, and, when released,
to spring back again so as to remove the type from the printed surface. Such a
type-bar does not require to be operated by means of an electric current. Various
appliances as hereinafter instanced, can be used to bend it to bring its type against
the surface being printed upon.
The machine also comprises other novel features of the construction, hereinafter
specifically described and relating to the construction of the keyboard, to the means
used in connecting the keys with their respective type-bars, to the means for
shifting the paper-carriage, as well as to certain features of the paper-carriage

THE FRAME OF THE MACHINE.
The principal parts of the frame are the base A Figures 1, 2, 3, 16, the semi-
niscules fulorum Îl which sunports the lovers which transmit the movements of the

page_text: key-levers to the type-bars, the semi-circular support A' upon which the type bars
are held and moved, the part A³ which upholds the magnet, and the part A' which
supports the paper-carriage and the mechanism more immediately therewith
associated. The fulcrum A' extends across the machine above the key-levers, and
is supported by the uprights a, a' which in turn are secured to the base A.
A series of brackets, such as shown at A, Figure 3, and in number corresponding
to the type-bar levers, are attached to, or made part of, the fulcrum A. The type-
bar support A is upheld by the posts A which, in turn rest upon the fulcrum A¹.
The support A is substantially two semi-circular segments a², a³. The part A³ is
conveniently supported from the segment a² at the right-hand side of the machine.
The part A is an upright attached to a cross-plate at which is in turn, fastened to
the uprights a, a¹. Minor details of the frame can be referred to more conveniently
hereinafter in connection with the movable parts of the machine.

page_text: its contact with the inking-pad Z which is held in the recess a in the segment a³.
As the type-bar is withdrawn forward the type drops onto the inking pad. The
offset is also useful in preventing the type-bar, in its forward position, from being
accidentally displaced. The perforations in the segments a³, a³ are of sufficient
height to admit of the movement of the type-bar in the manner described.
THE TYPE IMPRESSING MECHANISM.
The key-levers as stated, at a point between the ends of the lever, pass above
and bear upon the cross-bar E, Figures 2, 3, 16, 19. This cross-bar E is movable
vertically, and is borne downward with the key-lever. The magnet K, for the
purpose of conducting the electric current (which is supplied from an ordinary, 1
battery not shown) is provided with the customary wires k k¹. The circuit is
closed by the downward movement of the cross-bar E. The wire k leads from the
magnet and connects with the cross bar E and preferably by means of the
bracket e Figures 3, 19, to which the end of the wire is immediately attached.
The bracket is provided with a pin e¹ which, when the cross-bar and bracket 1
reach the downward limit of their stroke, comes in contact with a point . The
circuit is then closed, the current passing from the wire k to the bracket e and
pin e¹, thence to the point l, and thence to the wire k which leads to the battery.
The closing of the circuit causes the armature to be drawn to the magnet-
poles in the usual manner saving as the movement is modified as follows, the
armature is attached to the armature lever which is pivotted at ke, to vibrate
vertically, extended outwardly from the pivot at Figure 2, and upward at k³
Figures 2, 16 and extended inwardly from the pivot, and from the point at which
the armature is attached, and at its inner end provided with the hammer which
is over the point where the printing is done. The spring 10 acts, when the
circuit is opened or when the inner end of the armature lever is released, to lift the
inner end of the armature-lever. The armature, as seen in Figure 16, is held in an
inclined position. The magnet-poles are correspondingly inclined, and when the
inner end of the armature-lever rises the effect is to move the armature across as
well as away from the magnet-poles. This enables the hammer to be lifted the
requisite distance without moving the armature but a short distance comparatively
from the magnet-poles, for owing to the hammer being much farther from the pivot
than is the armature the latter moves through a shorter arc, and by reason of the
movement being in the direction described the armature is not drawn as far from
the magnet poles as would be the case were the movement directly outward there-
from. As the key-levers are successively operated the type-bearing ends of the
corresponding type-bars are successively brought into the same position, namely,
beneath the hammer and above that part of the paper to be printed. The
descent of the hammer then causes the type to be impressed upon the paper; after
which the hammer, by reason of the spring 10 rises and the type-bar is withdrawn
forward as previously described.

AND DOTATING THE

page_text: and provided with the slotted lug m" in which the pin m³ engages, the guide can
be adjusted toward, and from the roll so as to admit one, two, or more sheets of
paper between the roll and the guide-edge m', as may be desired for single or
manifold printing. The lever is provided with a dog m¹ which operates in con-
nection with the toothed segment m¹s and serves to hold the guide at any desired
adjustment. The end pieces m, m³ are fastened to the cross bars m6 m³ and those
in turn are held and adapted to be moved longitudinally in the sheaves m¹, m¹5
that are journalled upon bearings upon the part m³6.
The carriage is both shifted transversely in the machine and its paper-roll rotated
as follows; m16 represents a lever pivotted at m1, Figures 1, 2 and at its rear end
jointed to a bar m¹8 which, in turn, is jointed to a bell-crank m¹. This bell-crank
is pivotted at m to the paper-carriage and its inner arm m is jointed to a spring
pawl m, Figure 5, whose point is adapted to engage with the ratchet m, upon
the roll shaft m. By turning the lever m16 on its pivot m17 so as to throw its
handle m² toward the key-board, the bell crank m¹ is turned on its pivot, and the
pawl m, by engaging in the ratchet ms, causes the paper-roll to be rotated, and
by continuing to swing the lever in the same direction the carriage is shifted to
the right across the machine. That is, the arm m of the bell-crank, by the
described movement of the lever m16, is turned against the shoulder m2 upon the
extension m2 of the end-piece m³. The rotation of the paper-roll now ceases and
the continued movement of the lever m16 operates to draw the carriage to the right
across the machine. After the carriage has been shifted, and the lever m16 released
the spring m⁹ acts to draw the bell-crank back against the stop m30, into position
for the next lining operation, after which the carriage in its movement to the left
operates to swing the lever m¹ upon its pivot in the opposite direction. According
to the are through which the bell-crank turns is the extent of the rotation of the
paper-roll. To provide for rotating it a distance of two lines what is termed the
two line stop m³, Figures 4, 7 is used. This stop is pivotted at ms, and when it
is desired to rotate the paper-roll a two line distance the stop is turned up on its
pivot, out of the field of the bell-crank which now can be swung against the
shoulder m. Then when the lever m¹ is swung back the paper roll is rotated
accordingly. But when the stop is turned down, as shown in the full-lines, the
paper-roll is rotated a distance of but one line. By means of the thrust pin m
the spring pawl m" can be pushed downward out of engagement with the
ratchet m, whereupon the paper-roll can be turned freely in either direction.
THE LETTER SPACING.
The paper carriage is moved from right to left in the machine by means of the
gear N, Figures 16, 26, 27, and the coil spring n, Figure 3. The gear N is
journalled upon the bolt n¹ which passes through the: hub n of the gear and is
screwed into the part Y. The spring n encircles the bolt between the gear and the
part Y, the inner end of the spring being fastened to the bolt and the outer end to
the
gear. The gear N engages with the paper carriage rack-bar m². The shifting
of the carriage to the right winds up the spring, and when the gear is released the
spring acts to shift the paper-carriage to the left. The hub n³ is extended and
forms a bearing upon which the scape wheel n³ is fastened. H represents what
may be styled a scape-plate. It is slotted vertically at h and is arranged between
the scape-wheel and the gear N. The slot n is large enough for the scape-pláte to
be passed onto the hub n³, and it is sufficiently elongated vertically to enable the
scape-plate to be lifted and lowered in the manner and for the purpose presently
described. The bolt n¹ when in place is rigidly fixed by means of the nuts n' n³
but it does not bind the gear N, the scape wheel, and the scape-plate in their
respective movements; that is, the gear and scape-wheel can as one part rotate
reciprocatingly upon the bolt, and the scape-plate can be moved reciprocatingly
upward and downward between the gear and scape-wheel. The scape-plate is
supplied with the two dogs h¹, h³ which are designed to work in connection with

page_text: the scape-wheel. They are arranged upon the plate to be one, h¹, above, and the
other, beneath the centre of the scape-wheel, and they point in opposite
directions. The scape-wheel is at rest when the scapé-plate is in its down
position in which position the dog h¹ is in engagement with the scape-wheel.
When the scape-plate is lifted the upper dog becomes disengaged and the lower
dog becomes engaged, and the spring n acts to rotate the gear N and scape-wheel
à distance equal to that of the movement of the point of the lower dog. For while
the upper dog is fixed the lower dog is pivotted, and it is turned to and fro as
indicated by its two positions shown in figures 26, 27, respectively, and when the
scape-wheel engages with that dog h the dog point moves with the scape-wheel
until the dog-point encounters the stop h³ whereupon the further movement of the
dog and scape-wheel is arrested. When the scape-plate is lifted and the dog h
disengaged therefrom, the spring h' acts to turn the dog on its pivot back in the
direction of the spring, as in Figure 27. The scape-plate is moved upward and
downward as follows: O represents a rod attached to the scape-plate and extending
downward and engaging with the cross-bar, E, Figure 16, and when a key lever is
depressed the cross-bar and scape-plate are drawn downward with it. The con-
nection of the hook with the scape-plate is made vertically-adjustable, as indicated
in Figure 16. When the key-lever is released the cross-bar E and scape-plate are
lifted by the action of the double arm 01 0¹ and the spring O' the double-arm
being pivotted on the bar b¹, and extended to the rear of the bar and the spring O'
acting, as indicated in Figure 2, to bear downward upon the extension. Thus
every time a letter is printed the scape-plate acts to release the paper carriage and
allow it to move to the left. When it is desired to shift the paper-carriage rapidly
the lower dog can be thrown out of the plane of the scape-wheel by means of the
thrust-bar O³, Figures 26, 27, 28, 29, 30, 31, which is adapted to be moved longi-
tudinally, transversely in the machine. The bar has a bevel 0. The dog h¹ is
correspondingly bevelled. By thrusting the bar from its position shown in
figure 28 into that shown in figures 29, 30, the dog is wedged outward from the
plane of the scape-wheel. The bearing O³ is extended outward from the scape-
plate and sufficiently to hold the dog when thus wedged outward. The spring h
by reason of its being constructed as shown is a compound one and it acts to
replace the dog in the plane of the scape-wheel when the thrust bar is withdrawn.
THE WORD SPACING.
The scapement above described is also used in the word-spacing. The scape-
plate, however, in word-spacing is actuated by the spacer D, spacer-levers d¹ d,
and the cross-bar E, and independently of the keys B, and type-impressing
mechanism, and as follows: the levers d¹ d, in their downward movement, act to
bear the cross-bar down, and the scape-plate H acts, as before described, in
connection with the other parts of the escapement mechanism to effect the shifting
of the carriage. The type impressing mechanism meanwhile is not operated for
'the reason that the wire k¹ does not lead directly to the magnet but, as shown in
figure 20, to a band k¹, of material suitable for conducting an electric current, which
is attached to the lever d³, and which, when the lever d' rises, comes in contact
with a loop k (also of material for conducting electricity) which is supported as
a fixture say by means of the post k¹³-from the base A. The loop is so made and
adjusted that, when the spacer is operated, the band k¹¹ is drawn downward so
as to be out of contact with the loop. The wire k¹ leads from the loop to the
magnet. Hence the connection is broken, and the magnet ceases to act, whenever
the space is used.

page_text: than in lower case printing. This in turn involves depressing the key-levers b' a
greater distance than in lower-case printing in order to obtain the necessary
additional throw of the levers I. This additional depressing of the key-levers
must precede the operating of the type impressing mechanism, and this is
accomplished as follows: c represents a bar arranged crosswise in the machine,
beneath the upper case key C and journalled at o' to the supports c³, and so that
the bar can be turned upward and downward as shown in the two positions
respectively in figures 10, 11. The upper case levers oc, by means of the arms c',
and the pin attached to the arm c and engaging in a slot as in the bar o', cause,
08
when the levers co are depressed the bar c' to be turned down into the position of
Figure 11. This in turn, and by means of a connecting rod c leading from the
bar and connecting at Figures 3, 17, 18, with the swinging contact arm L,
causes the last named part which carries the point l, and is pivotted at □ to be
turned from its position of figure 17 into that of Figure 18, and in so doing to
displace the point 6 from beneath the point e¹ and to bring into place another, but
shorter, point. Then as the upper case is depressed the point e¹ comes into
contact with the point and the circuit is closed as before and the hammer caused
to depress the type-bar and the upper case letter thereby to be imprinted. But,
owing to the point being lower than the point the hammer does not operate
until the type-bar is moved the desired additional distance. When the upper case
key rises again the movement of the bar c¹ is reversed and the contact-arm L
swung back into its original position. To enable the type-bars to be moved
further rearwardly as described the upper-cases top P Figures 1, 2, 3, is employed.
The stop is semi-circular in outline, and is arranged in part of the segment a and in
width is equal to the distance between the types J. It is connected with the upper
case levers cc by means of the rods p p. When the levers c c are depressed the
rods p p draw the stop sufficiently downward to enable the type-bar to be moved
rearwardly until its shoulder encounters the segment a². But on releasing the
levers cc the springs pl p¹, which bear upon the frame A¹ and upward against au
adjustable stop or shoulder p' on the rods p p, act to lift the stop P into its original
position, as in figure 3, in which position by reason of the shoulder j³ coming against
it, the stop P prevents the type-bar from being moved rearwardly beyond the point
for lower-case printing. When the bar c¹ is upturned the key-levers b¹ encounter
the face and are thereby prevented from being moved further downward, but
when the bar c is turned downward the key-levers b¹ can be moved further
downward, and as desired for upper-case printing..
To enable the keyboard to be composed of fewer keys without diminishing the
number of key-levers and types a device such as shown in figures 2, 13, 14, 15
may be used.
In the place of attaching the keys directly to the key-lovers they
are attached to thrust, crank, pins, 6 as they may be termed. That is, these pins
are made with a crank like off-set 6, and they pass downward through a guide-
plate 6, and then through a shifting-plate 6 which, as shown in figures 1, 2, is
supported by the arms 60 pivotted at 67 and 68, and so that the plate 6 can be
shifted transversely. in the machine and so as to cause the lower ends of the pins 6³
to be turned to come either over the right-hand one or the left hand one of a pair
of key-levers, That is, the key-levers, as indicated in figure 15, may be classified
in pairs, b', and for each pair there is one pin 6', when the plate 6 is shifted one
way say to the right-the pins are respectively over the right-hand ones of the
various pairs of key-levers, and when the plate 6 is shifted in the opposite
direction the pins are respectively above the left hand ones of the key-levers, and,
thus by shifting the pins 6 as described the key-levers may be operated with half
as many keys. The springs 610 serve to raise the keys. In Figures 32, 33, 34, a
modification is shown. The pins 6' are straight and are rigidly attached to the
keys, and the key-levers to pins, are shifted as one part, and so as to bring the
pins first over the right-hand ones, and then over the left hand ones of the various
pairs of key-levers. The shifting plate b³ is conveniently moved by means of the
handle b. Figure 1..

page_text: The paper carriage and the parts immediately therewith associated can, within
a limited degree, be adjusted vertically by means of the screw. Y', Figure 16. This
screw is held above in an extension a" of the part A' and its lower end works in,
an extension Y of the plate Y.
In case it is desired to operate the type-bar hammer mechanically a device
shown in Figures, 2, 16, 21, 23, 24, 25, 30, can be used. I represents a rod.shaped
at its upper end to hook onto the hammer-lever k Figure 16, and extending thence.
downward and at its lower end, Figures 2, 25, being extended laterally and pro-
vided with a block t having an inclined face t¹. This block comes into the plane.
of a scape-wheel ** which encircles a. drum which in turn, is journalled on the
bolt which passes from the outer side, through the drum and is screwed into
the downward extension m37 of the cross-bar me. The washer to serves to confine
the drum in place upon the bolt. A coil spring to around the bolt connects the
bolt with the drum. When the paper-carriage is shifted to the right its rack-bar,
engaging with the gear t which encircles the case or drum, and during the
referred to-movement of the paper-carriage, is; by means of the eccentrically-
pivotted wedges to, fastened to the drum causes the drum to rotate upon the bolt
and the coil-spring to be wound up. to represents a scape-plate having a slot t10
to enable the plate to pass onto the drum and to be moved vertically thereupon.
It has a lower fixed dog t¹ and an upper dog t¹ pivotted at 19 and adapted to be
moved between the stops t13, t¹ the dog being turned one way when released by
the scape-wheel and the opposite way by the spring t¹. The action of the scape-
plate is analogous to that of the scape-plate H. When the scape-plate t by means
of the ties the leading to the cross-bar E, is drawn downward and upward with the
cross-bar E and the scape-wheel to released by the movement the drum rotates a
distance of one tooth of the scape-plate to. This in turn causes the scape-wheel t*,
which is now bound to the drum by means of the pivotted wedges t, to rotate one
tooth, and as the teeth of the scape-wheel bear upon the block t the rod T and
hammer k are drawn downward every time the scape-wheel or ratchet t' moves
as described. The spring 18 acts to lift the rod T after the tooth of the scape-
wheel t¹ has passed the block t. When the drum is moved in the opposite direction,
as in winding the coil-spring the wedges do not exert a binding action. The
hammer escapement ratchet 2 rotates when the paper-carriage escapement is
stationary, as the feeding of the paper-carriage occurs just after the key is released,
whereas the hammer escapement acts just before the key is released.
The levers I yield and bend on one encountering the segment a³ as indicated by
the broken lines in Figure 3, the object being to enable the key-levers to be
further depressed after the levers I have reached the rearward limit of their stroke
and when the type impressing mechanism is released to give time for the hammer
and type to rise from the paper before the type-bar is moved forward.
The above described mechanism, by omitting the inking pad, and employing
sheets of wax or other substance suitable therefor, can be used to stamp matrixes
in the place of type-writing, the matrixes being formed in the wax or other
substance which is supported on the anvil of the paper-carriage.
The forward end of the type-bar is confined vertically by the frame A* as the
type-bearing end of the type-bar is sprung downward by the hammer.
