page_text: or hand wheel is formed or provided with a series of depressions 11, arranged a
line-space distance apart, into which is adapted to take a hold-fast dog 12 formed at
the end of a plate secured by a screw 13 to the right hand standard. The device 9
at its lower rear end, where it joins the bent plate 8, stands away from the surface
of the feed-roller, and forms therewith a mouth for the ready introduction of the
paper from the rear of the machine. From this point the said device 9 gradually
approaches the periphery of the feed-roller until at its upper forward edge it runs
or bears in contact therewith, in order to afford a positive feed for the paper when
introduced. Inasmuch as the upper forward edge of the device 9 terminates
concentrically with the surface of the feed-roller, it has a tendency to guide or
deflect the paper rearwardly in the direction of rotation of the feed-roller, but
this is overcome by having the upper portion of the feed roller revolve in a
circular groove 14 on the underside of the platen or impression bar 7, and by
bevelling or slightly chamfering the lower front portion or edge of the latter, as
seen at 15, adjacent to the upper end of the device 9, whereby when the edge of
the paper to be printed is fed past the upper edge of the device 9, it is deffected.
or turned upwardly by said bevelled or chamfered edge 15 and caused to ascend in
a vertical path along the vertical face 16 of the bar 7 and between it and a shield-
plate 17, which at its lower end is secured to the bottom of an upright or
standard 18, preferably cast integral with the base-plate and centrally thereof
widthwise.
The paper-carriage is prevented from rising at its front side by reason of the
fact that the front portion of the rack-bar slides in an undercut or groove 19 formed
at the bottom of the upright or standard, and is prevented from rising at its rear
side by means of an overlapping plate or finger 20, detachably connected to the
base-plate by a screw 21.
The paper-carriage is adapted to be fed step-by-step towards the left by means
of a driving pawl 22, which is pivoted to a lever 23 that is fulcrumed at 24 upon
the base-plate. The said lever is also provided with an integral tooth or dog 25
arranged substantially at right angles to said lever, and adapted to engage with the
teeth of the rack-bar to restrain the driving-pawl from feeding the paper-carriage
more than one notch, tooth or letter-space at a time, as will hereinafter more fully
appear.
To the free end of the lever 23, at which the driving pawl is pivoted, is also
pivotally connected the rear forked end of a sliding rod 26, upon which is mounted
a coiled spring 27, the rear free end of which bears against both the driving pawl
and the lever 23, on opposite sides of the common pivot 28, and which at its front
end bears against a lug 29 formed on the base-plate. The said lng is slotted to
permit of the passage therethrough of the said sliding rod 26, which at its free end
is bent laterally and connected to a spacing lever or key 30, pivoted at 31 in down-
ward extensions of the base-plate. By depressing said spacing lever or key, the
said rod 26 is adapted to be drawn forwardly, compress its spring, vibrate the
lever 23 and withdraw both the driving pawl and the locking dog from engage-
ment with the teeth or notches of the feed-rack, the arrangement being such that
the moment the driving pawl is freed from engagement with its tooth or notch, the
spring 27 operates to vibrate said pawl about its pivot and throw its driving end
one notch or tooth to the right, as indicated at Figure 7, so that upon releasement
of the said spacing lever or key, the said pawl will engage with the next succeeding
tooth or notch of the rack, and by the distension of the spring 27 act to force or
drive the feed-rack and the paper-carriage one notch or letter-space towards the
left. At the same time the spring 27 operates to also vibrate the lever 23 about
its pivot and cause the dog 25 thereon to engage with another tooth or notch of the
feed-rack, and thus prevent the driving pawl from feeding the carriage more than
one notch at a time." The construction and operation are such that the driving
pawl acts on the left hand side of a notch in a direction towards the left, and the
locking dog acts on the right hand side of another notch towards the right or in
substantially a direction opposite to that of the driving pawl. The driving pawl

page_text: and the locking dog are relatively so arranged that immediately the pawl has moved
the carriage a letter-space distance, the dog comes into engagement to effectually
prevent any, overthrow or extra movement of the carriage, due to sudden action or
momentum of the feed. The upright or standard 18 is split or cut away vertically
from its top to near its bottom, as indicated at 32, and through this cut-away the
dog is arranged to work.
The type 33 are preferably made of soft rubber and are moulded upon or formed
integral with a soft rubber or yielding support 34, which latter at or near its lower
edge is secured to a vertically-arranged segmental metallic plate or support 35,
which at its ends is secured by screws 36 to arms 37 extending from a hub or
bearing 38. The rubber type-support or band 34 is connected to the segmental
plate 35 in such a manner that the type stand well above the upper edge of said
plate, and said type-support is preferably attached to said segmental plate by
clamping its lower portion between the outer surface of said plate and the inner
surface of a segmental metallic strip 39, of a length equal to that of the segmental-
plate, a series of small screws 40 passing forwardly through holes in said plate an 1
coinciding holes in the rubber support, and entering threaded holes in the outer
clamping strip 39.
The said hub or bearing 38 is mounted upon a journal or pivot 41 having a
shoulder 42, and secured to the base-plate by a washer 43 and a screw 44. The
screw passes through a slot 45 in the base-plate, which enables the journal or pivot
and parts carried thereby to be properly adjusted to effect the best results in the
printing. By moving the pivot back or forth, the type are brought nearer to or
further from the platen, as may be necessary.
The upper end of the pivot or journal is threaded to receive a threaded nut 46,
which clamps upon the bearing or hub the outer end of an indicator or pointer 47,
the said outer end having a large perforation centrally to fit over the upper end of
the journal, and having also two diametrically-opposite smaller perforations to fit
over two small pins 48 projecting upwardly from the hub, in order to prevent the said
indicator or pointer from having any motion independent of the said hub or bearing.
The indicator is preferably spear-shaped at its outer end, and is formed with a
cup or depression 49 to receive the finger of the operator and facilitate the vibration
of the indicator and the oscillation of the type.
In front of the feed-rack and near each side of the base-plate are provided two
posts 50, which support a top-plate 51 that bears the key board or index-plate 52.
The said top-plate is preferably formed with a segmental depression 53, adapted to
receive the index, which is correspondingly shaped and printed on paper or card-
board and preferably covered with a piece of glass, celluloid, or other transparent
medium 54. The top-plate is provided with a sunken portion 55 between the
journal and the index, to form a rest for the hand, and also to facilitate the move-
ment of the hand during the swinging or vibration of the indicator, which, as shown,
is arranged to overlie the top-plate.
Upon each of said posts 50 is secured by screws 56, an arm or bracket 57, which
at its free end supports an inking roller or equivalent device 58, adapted to impart
ink to the type.
By swinging the indicator any of the type may be brought to the impression or
printing point.
The type are caused to make their impressions on the paper by the following
means: Pivoted at 59 in the upright or standard 18 is a vertically arranged plate 60,
which works in the slot 32, and which at its upper end is provided with a type-
presser 61.
At 62 is pivoted or loosely connected the rear end of a printing lever 63,
which is fulcrumed at 64 in a post 65 on the base-plate, and which terminates at its
outer end on the left hand side of the machine preferably, in a finger-piece 66. To
said plate 60 is pivoted at 67 an arm 68, which extends forwardly and downwardly
and terminates in a fork 69, which embraces the sliding rod 26 and stands against a
stop or projection 70 on said rod.
By this construction and arrangement when the finger piece 66 of the printing

page_text: lever is depressed, the plate 60 is turned about its pivot as a lever, and the type-
presser is caused to move rearwardly and the arm 68 forwardly, these devices
being on opposite sides of the pivot of said plate, with the result that the type-
presser acts to force the type behind which it plays, through an opening 71 in the
shield, and cause its face to leave an impression upon the paper; and simultaneously
the arm, by its forward movement, operates to push the spring-actuated rod 26
forwardly and cause the driving pawl and locking dog to both disengage from the
feed-rack. Upon releasing the printing lever, the spring 27 operates to return it,
the plate 60, and the pawl and dog, to their normal positions, the pawl at the same
time acting to feed the carriage one letter-space, and the dog to limit the feed.
The said plate 60 is provided with a pin 72 between its pivot and the type
presser, which is adapted to enter any one of a series of openings 73 formed in the
segmental plate below the type-band. Each of said openings is arranged directly
under and in line with one of the type, with the center of the opening coincident
with the center of the type; and by this arrangement the pin is adapted to lock
the segment and body of type securely in position during the printing movement,
and thus insure absolutely accurate spacing between letters and words.
The said locking pin 72 is connected to the plate 60 by a pin 74 fitted to a
slot 75 in the plate 60; and the body of the pin is supported in a tubular bushing 76
inserted in the upright or standard 18, the arrangement being such that the forwardi
or operating end of the pin is caused to slide horizontally in a right line to and
from the opening 73 in the segmental plate, during the back and forth movements
of the vibratory plate 60.
At Figure 6 the type presser is shown as having forced the type to the platen,
the rubber band or support yielding to permit of the same; the pin is shown as
locked with the perforated type segment, to hold the same against lateral move-
ment; and the carriage feed and locking devices are shown as retracted ready to
advance the carriage a letter-space distance upon the return of the type presser
and segment-locking pin to their normal positions.
The type are arranged in one continuous row or in one horizontal plane, and the
series of segment holes or openings are similarly arranged, while the characters on
the key, board or index, arranged in a horizontal plane, are disposed in two
concentric arcs, for the purpose of obtaining characters of a size considerably
larger than that of the types themselves, in order that the operator may more
readily operate the machine without unduly tiring the eyes. From the center
of each character on the back row extends rearwardly a short radial line 77,
and from the center of each character on the front row extends rearwardly a
longer line 78, the characters in both said rows being arranged to alternate so
that each character of the lower row stands in a line midway between two
characters on the upper row, and the two series of radial lines being so arranged
that beyond the rear row of characters they lie side-by-side at equal distances
apart and corresponding to the distance apart from center to center of the types.
From what has already been said the operation of the machine will be readily
understood, but the following brief description thereof is added: If it be desired
to write the word "The," the finger may be placed in the cup or depression 49
and the indicator swung towards the right (Figure 1) until the pointer registers
with the longer radial line extending to the capital letter "T." By this move-
ment it will be understood that the capital type "T" is brought to the printing
point, the type being of course arranged relatively to the arrangement of the
characters on the index. The printing lever is now depressed at its outer end,
the plate 60 is vibrated, the pin 72 caused to enter the opening directly beneath
the type "T," the type presser 61 caused to press or force the capital "T"
type through the opening in the shield against the paper, and the driving pawl
and locking dog caused to withdraw from the rack-bar through the movements
of the arm 68 and rod 26. Upon releasing the printing lever the parts all
return to their first positions and the carriage is moved a letter-space distance
by the driving pawl. The indicator is then again swung further to the right

page_text: until the pointer thereon registers with the short line radiating from the lower
case "h," to bring that type to the printing point. The printing lever is again
depressed at its outer end, and the actions of the printing, locking and feeding
devices are repeated. The indicator is then swung towards the left until the
pointer registers with the longer line radiating from the lower case "e," to bring
that type to the printing point, and the printing lever is again depressed as
before. It is intended that the right hand shall operate the indicator to bring
the type to printing position, and that the left hand shall actuate the printing
lever to effect the impression, locking and feeding. To space between words, the
space-key or lever 30 is actuated, while the indicator and printing lever remain at
rest. The printing lever may be provided with a spring, as shown at 79. The
shield operates to prevent the type presser from printing either of the adjacent
type simultaneously with that one it is desired to print. The soft rubber yielding
elastic support permits the type presser to readily and squarely present the type
to the paper, and upon recession of the type presser to return the type by reason
of its inherent resiliency. The type presser is purely what its name indicates.
It operates simply to effect the impressions by pressure instead of a blow.
To return the carriage for the beginning of a new line, the space-key is
depressed, which releases the driving pawl and locking dog.
Having now particularly described and ascertained the nature of this said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is-
