page_text: rod I is located alongside of and parallel with the platen D, and is adapted to
receive the paper thereunder and guide it in its movement about the platen D.
An upwardly extending lever L is pivoted at its lower end to the base plate A and
is provided with a forwardly extending thumb piece L'. A pawl M is pivoted on
the lever L and is adapted to engage with a rack N on the carriage C. The
pawl M is provided with a forwardly extending thumb piece M¹. A retrieving
spring O is attached at one end to the lever L and at the other end to the post P
fixed on the base plate A. A stud R, projecting downwardly rigidly from the
vertically moving type-bar-supporting channelled bar S hereinafter to be more
fully described, is adapted as the channelled bar S is forced downwardly to strike
against the thumb piece L' and force the pawl M forward sufficiently to engage the
next tooth of the rack N, and thereupon as the channelled bar is raised the
retrieving spring O through pawl M, forces the carriage C rearwardly a prescribed
distance.
Two arms 13 rigid on or integral with post P project forwardly therefrom, and
a letter plate 14 located at right angles to the platen D is secured rigidly to the
ends of the arms 13. The letter plate 14 has impressed therein or affixed thereon,
the letters of the alphabet occupying a portion of the length of the plate, the
numerals, marks of punctuation and other characters occupying in two lines the
remaining longitudinal portion of the plate. A comb 15, one recess of which is in
front of each one of the letters on the letter plate and in front of each two numerals
or characters on the letter plate, is adapted to receive and guide the stylus on the
type bar thereby guiding and moving the type bar into the exact position necessary
to properly print a letter above the platen D.
The
A type bar frame T consisting of the channelled bar S and two rigid rearwardly
extending arms 16, is pivoted at the rear ends of the arms 16, to the arms 13,
opposite the post P. The bar S is located in front of and parallel to the letter
plate 14 and has a limited oscillating movement vertically a little in front of and
below the comb 15. A spring 17 affixed at one end to the post P bears at its free
end against the underside of a projection on an arm 16, and is adapted to hold the
channelled bar S upward yieldingly. A slightly yielding stop 18 is secured rigidly
at one end to the arm 13, and projects forwardly terminating over the platen D at
such a point as to receive against its free end the downward thrust of the channelled
bar S about at the moment of its reaching its extreme movement downwardly.
channelled bar S is open at the top throughout its entire length, and is open
centrally at the bottom above the platen D, and for a little distance on each
side of the platen. The channelled bar S is provided with longitudinal ways 19,
in its side walls, in which the type bar or type bar frame is supported and travels.
The type bar in this improved device is supported in a frame or carriage 20,
consisting of the elongated plate or bar 21 having at its ends downwardly projecting
lugs or ears 22, in which the type bar 23 is journalled. This type bar 23 is
provided with two longitudinal faces 24 and 25, which in transverse section are
located at a slight angle to each other, the transverse line of the two faces of the
bar being preferably the chords of a circle about the axis of the type bar, the
circle having a radius of the same length as the distance of the edge of the faces
from the axis of the type bar.
On these faces are constructed two different sets of letters and characters, thus
on the face 24 are placed the capital letters, the numerals and if desired such
characters as £,%, etc tera, and on the face 25 are the small letters, marks of
punctuation and fractions or other characters. The arrangement and number of
the characters may be varied to suit the user, but the small letters on face 25 are
placed opposite the same capital letters on face 24, and the letters, figures and
characters on the letter plate 14 are arranged in the same order as the letters,
figures and characters are arranged on the type bar, the arrangement and location
of the letters, figures and characters on the letter plate being such with reference
to the comb 15 and the letters, figures and characters on the type bar, that, when
the stylus 26 affixed to the type bar, is adjusted to enter a recess of the comb

page_text: opposite a letter, figure or character, the same letter, figure or character on the type
bar will be over the platen D centrally. The letters, figures and characters on the
faces of the type bar are in raised type, so as to be adapted to print on paper above
the platen D.
This type bar 23 is provided with rigid pins 27, one on each side, adapted to
strike against the under surface of the bar 21 and prevent the tilting of the type
bar except only in one direction to such limited extent as is necessary to bring the
face 24 into position directly downwardly from the axis of the type bar, in which
position the type bar is adapted for printing the letters on face 24, and in the
other direction so as to bring the face 25 into position directly downwardly from
the axis of the bar, in which position the type bar is adapted for printing the
letters, figures or characters on the face 25.
To enable the operator to tilt the type bar while the machine is in use, a finger
plate 28 is pivoted centrally on a post 29 fixed in the bar 21, which plate 28 is
connected by a rod 30 to the type bar, the rod being pivoted to an ear on plate 28
and to an ear on the type bar. The type bar is locked yieldingly in position with
the face 24 or the face 25 directly downwardly, by the retrieving spring 31, secured
at one end to a bracket 32 fixed on the bar 21, and at the other end to an arm 33,
fixed in the end of the journal of the type bar and projecting therefrom radially
through the prolonged line of junction of the faces 24 & 25. By this construction,
when the outer end of the arm 33 is thrown to the right or left of the axis of the
type bar, the retrieving spring locks it yieldingly in that position, the spring being
sufficiently elastic to readily yield to finger pressure on the plate 28. It will
be understood that, by this construction, the operator can tilt the type bar readily
so as to print the letters, figures or characters on either the face 24 or 25 in such
sequence as desired, while shifting the type bar to right or left by the thumb and
finger of the right hand grasping the stylus 26, the little finger being used to tilt
the plate 28. The stylus 26 is provided with a downwardly projecting guide 34
adapted to enter the recesses of the comb 15.
An inking roller 35, constructed of some absorbing material, is journalled on
elastic arms 36 by which it is held yieldingly against the type in the open space in
the bottom of the channelled bar S. The elastic arms, 36, are secured to the free
upper ends of the bifurcate lever 37 which is pivoted at its lower end on the base
plate A. A connecting rod 38 is secured at one end to the lever 37 and at the
other end to the stud R, the connecting rod being arranged at an angle to the
lever 37 so that, as the channelled bar S is forced downwardly, the lever 37 will be
forced outwardly toward the left, and, as the channelled bar S rises, the lever 37
will be drawn inwardly toward the right, whereby the inking roller 35 is caused to
reciprocate in front of and against the letters on the type bar above the platen D
with each downward and upward motion of the channelled bar S.
For giving an alarm to the operator, a small bell 39 is suspended by an arm
from the rear of the arms 13, which bell is arranged to be struck by a centrally
pivoted swinging lever clapper 40, having at one end a knob 41 for that purpose.
This lever 40 is pivoted to the arms 13 and is provided with a therefrom pendent
tripping rod 42. The rod 42 is so pivoted in the outer arm of the lever 40 that it
swings freely in one direction, while in the other direction, it engages a downwardly
extending lug 43 integral with the lever 40 whereby the rod is held vertically
against swinging in the other direction. A tripping arm 44, sliding on the rod I,
is secured adjustably thereto by means of a set screw 45 turning through the
tripping arm against the rod. This tripping arm 44 is constructed and arranged to
engage the tripping rod 42 as the carriage C moves toward the rear of the machine,
and thereby to swing the lever 40 carrying the knob 41 away from the bell until
the tripping rod 42 slips off the tripping arm 44 when the knob is thrown sharply
against the bell by the resilience of the spring 46, which is affixed at one end to
the bell-supporting arm and at the other end is connected movably to the lever 40.
When the carriage C is returned to the front, the tripping arm 44 merely swings
the tripping rod 42 in the manner shown by dotted lines in Figure 8 without

page_text: moving the lever 40. The tripping arm 44 can be adjusted and secured on the
rod I, at any place necessary to give the alarm at any desired point of the move-
ment of the carriage.
In the use of checks, bills of exchange, promissory notes and other similar papers
expressing valuable consideration, it is found desirable to perforate or so mark the
instrument with the numeral characters as to protect the same against any improper
change of the amount stated therein. For this purpose an additional type bar 47
is provided having a stylus 48, which type bar is adapted to be detachably inserted
and to travel in the chanuelled bar S. This type bar is provided with type
representing the nine digits, a cipher, a money character mark and a star, and may
be provided with other characters if desired. The type 49 on this bar 27 are
constructed with a series of downwardly projecting teeth or points in the form of
the figures and characters represented, which points are adapted to perforate the
paper, while at the same time they may be inked with indelible ink, supplied by
the inking roller 35. By this form of type having the serrated, toothed or pointed
construction, the paper may be perforated and the apertures so inked as to be
entirely ineradicable, while the apertures cannot be filled in as has been done
where the figures were cut from the paper. As the type used for this perforating
process are preferably much larger than the type ordinarily used on the type bar,
a removable character plate 50 is provided on which the same figures and
characters are arranged in the same order as they are on the type bar 47, and
this character plate 50 is provided with a comb 51 having recesses that are twice
as far apart as the recesses in the comb 15, so that when the plate 50 is placed upon
the plate 14 the recesses in the comb 51 register with every other recess in the
comb 15. The letters and characters on the plate 50 are located opposite the
recess in the comb 51, and the type 49 on the type bar 47 are arranged at corre-
sponding distances apart. To secure the removable plate 50 in position on the
plate 14, this plate 0 is provided with a central hook 52 and with hooks 53 at
the ends of laterally extending arms 54, which hooks are adapted to engage the
plate 14 at its front and rear respectively, and hold the plate 50 in position
detachably thereon. Other means of securing the removable plate 50 to the
plate 14 could be used.
Instead of the removable plate 50, the plate 14 could be used, having thereon
the numerals and characters properly arranged for use with a type bar 47, having
perforating type 49, or perforating type like the type 49 could be constructed on
the type bar ordinarily used with the type writing machine, the perforating type
being provided instead of some of the type thereon or being added thereto by
extension of the type bar longitudinally.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondent, I declare that what I claim is :-
1. In a type writing machine, the combination, with a vertically oscillating frame
hinged at one side to a fixed support but having no lateral motion thereon, of an
independent type bar frame supported and sliding horizontally in ways in the
vertically oscillating frame, parallel with and at a distance from the axis of
oscillation, and a type bar having two sets of type in longitudinal parallel lines,
which bar is pivoted in the type bar frame being thereby tiltable transversely of
its long axis independently of the type bar frame, substantially as described.
2. In a type writing machine having an elongated type bar frame or carriage
constructed to travel end wise on ways therefor in the machine, a type bar having
thereon two sets of fixed type arranged in parallel lines at an angle to each other,
which type bar is journalled in the type bar frame so as to be tiltable limitedly
laterally therein, a spring secured to the type bar frame and to an arm on the type
bar and so arranged as to swing past the axis of the bar when the bar tilts, the
spring being adapted to act as a yielding lock to the type bar, and means for tilting
the type bar, substantially as described.
