Improvements in Machines for Producing Indented Type Impressions
upon Paper or other suitable Material.
I, HENRY HARRIS LAKE of the firm of Haseltine Lake & Co. Patent Agents,
Southampton Buildings in the County of Middlesex, 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 :-
The invention relates to a machine for producing indented type-impressions upon
paper or other material, which impressions may subsequently be used as stereotypo
molds. The invention consists in the construction of the apparatus as hereinafter
more particularly set forth, in which the material which is to form the matrix, and in
which the type are to produce their indentations, is disposed in front of an annular
type cylinder, in which cylinder are radial chambers in which the type are placed.
The hammer is disposed inside the cylinder, and is actuated to strike and press on the
protruding rear end of any of the type, which may be presented to it. The types are
movable longitudinally, and are arranged in the same horizontal plane as the hammer,
so that the rotation of the cylinder on its axis brings any one of the type in place in
front of the hammer. Consequently, when the hammer delivers its stroke, it causes
the type in front of it to move longitudinally, so that the type is driven into the paper,
wax, or other material which is to form the matrix. This material is then moved a
certain distance to the right to space the letters, and the cylinder is again adjusted so
as to bring another type in front of the hammer, and this type is caused to indent
itself in the same way; and thus a series of indentations is made upon the paper
corresponding exactly to the letters which would be printed by the type if the faces
of the type were inked. The matrix being thus formed is removed from the machine
and serves as a mold for stereotyping or electrotyping in metal in the ordinary way.
The important features of my invention are:-
First. The annular type cylinder in which the movable type are disposed within
which cylinder is arranged the hammer which moves the individual type longitudinally
and outwardly, to cause them to produce their impressions.
Second. The hammer and its associated mechanismn which causes the hammer to
strike not a sudden blow on the type, but to force or press the type into the material
of the matrix for a measured distance.
Third. The construction of the hammer mechanism, so that it shall act positively
on the hammer, and operate with greatest force when the hammer approaches the
end of its inward stroke, and hence has forced the type most deeply into the
matrix.
Fourth. The mechanism whereby a rotary type wheel is turned in different
positions by the oscillation or vibration of a pivoted bar or plate operated upon by
wedges or cams placed at different distances from the center of oscillation, said cams
being associated with the finger keys.
Fifth. The construction whereby power from an outside source is caused to
actuate the various mechanisms embodied, so as to reduce the manual labour of the
operator practically to such as is necessary only for the adjustment of the parts
and the regulation of the time applying the power.
Sixth. The novel construction of the letter spacing mechanism.
Seventh. The arrangement of two or more tiers of type in the cylinder and the
means of raising and lowering said cylinder in order to move any given tier into
the plane of movement of the hammer. By multiplying the number of tiers of type,.
many different letters or characters may be used

and the bar 15. Similar numbers of reference indicate like parts.
I will first describe the mechanism whereby on the pressure of a finger key, a
movable type is adjusted in proper place in front of the material upon which the
character is to be impressed, and which mechanism, by continuing its operation, causes
the type to be struck by the bammer and moves inwardly so as to produce said
impression. 1 is the table or bed of the machine, on which are two standards 2.
Between the standards 2, extends a curved fulcrum bar 3, dotted lines, Figure 2,
which passes through holes in the keys 4. It will therefore be understood that
when any one of these keys is struck by the finger in the ordinary manner of
the typewriter key, it will vibrate on its pivot bar 3. Said keys are separated by
washers indicated at 5.
The casing of the machine is formed in two parts. The lower part, 6, being
secured directly to the bed 1, and the upper part 7, resting upon the part 6, and also
upon the two standards, Figure 1. The part 7 is secured in place by the three
screws, which enter the lower casing 6, and also by the screws 10, which
enter the ends of the standards S. By removing these screws,
the upper
casing 7 can be separated from the lower casing so as to allow of access to the
interior mechanism. The casing 6 is open in front as shewn at 11, Figures Land 4,
so that the keys may extend through it. On the under side of each of the keys 4
and also on the under side of each key 65 hereafter referred to is a cam pro-
jection 12, and also a pin 18, The side of the projection 12, nearest the pin, is
bevelled or inclined, so far as to form a cam surface. Pivoted at its middle to a
standard 14 rising from the bed 1, is a semi-circular plate or har 15, to which are
attached cords 17, which cords are connected to the ends of springs 18, enclosed in
suitable casings. It will be understood, that when the curved plate 15 is vibrated
horizontally on its central pivot, it will be opposed by the action of one or other
spring 18, and that the tendency of the spring will be to bring the plate always
back again to its original position. The extremities of the curved plate 15 rest upon
curved rails 19, which are supported upon standards 20, as shown in Figures 1 and 13.
When a key 4, (or a key 65) is pressed down, the cam inclination on the front
edge of the projection 12, meets the inner side or edge of the curved plate 15, and
causes that plate to vibrate on its central pivot. If the key which is pressed down is
located just on one side of the central pivot, it will be obvious that the plate 15 will
be displaced or caused to oscillate over a greater are than when it is acted upon by a
similarly arranged key placed at a greater distance from the pivot. Consequently,
no two of the keys 4 or 65 will move the plate 15 for the same distance in arc. It

page_text: As the
will be understood, however, that the keys located on opposite sides of the pivot 14,
will cause the plate 15 to oscillate in relatively opposite directions. By the greater
or less movement of the plate 15, the various type are brought into position, so as to
be struck by the hammer. This will be more fully described further on.
key continues to move downward, the straight bottom face of its projection 12
comes in contact with a semi-circular plate 21, which extends underneath all the keys,
and which is supported upon rods 22, which rods rise from another curved plate 23.
The plate 23 is supported on a series of arms 24, dotted lines, Figure 13, which
radiate from the lever arm 25, which lever arm is pivoted at 26 to a bracket 27,
which extends downward from the frame 1. Consequently, when the lower edge of
the projection 12 meets the plate 21, it forces that plate, and hence the plate 23,
downwards, and so causes the lever 25 to vibrate on its pivot 26. At the end of the
lever 25, Figure 7, is a slotted link 28, into which enters a pin 29 on the dog 30.
The dog 30 is made in two parts, as shewn in sectional view, Figure 9, and from
each part projects a pin or roller 31, each of which pins enters a cam groove 32
formed upon the faces of brackets 33 and 34. 35 is a bent lever pivoted to the
bracket 36, which depends from the bed 1. The downwardly bent end of lever 35 is
connected by a spiral spring 35* to a pin which extends between the lower extremities
of the dog 30. The lever 35 is pivoted between the upper faces of the dog 30, and
also on the same pivot between the parts of said dog is a lever 37, which is pivoted
to the hammer rod. 38. The dog 30 is provided with a shoulder or step 39, which is
suitably placed so as to be engaged by the teeth of the wheel 40. The wheel 40 is
supported on a shaft 41, which extends between suitable bearings 41*, Figure 3,
depending from the bed 1. On the said shaft is a pulley 42, by means of which
motion is communicated to said shaft by a belt, as indicated in dotted lines, 43, from
an electric motor or other suitable source of power; the pulley, and hence the
wheel 40 being rotated in the direction of the arrow. The wheel 40 is loose upon
the pulley 41, but is provided with a segmental opening 44, Figure 7, in which
enters a projection 45 from the shaft. The projection 45 meets the end of the
opening, and so carries the wheel around with it. Between the projection 45 and
the end of the opening in the wheel, is interposed a spiral spring 46. The object of
this spiral spring is to act as a cushion so as to prevent the too sudden movement of
the wheel 40, and possible disarrangement of the mechanism.
The operation of the apparatus so far described, will now be explained. When
the key 4 is pressed down, the plate 23 is depressed, and the slotted link at the end
of the arm 25 is raised. Assuming the parts to be in the position shewn in Figure 1,
the effect of the raising of the slotted link 23 is to cause the rollers 31 on the dog 30
to traverse the cam groove 32, so that the toe or shoulder 39 on the dog 30 is
brought into position to be acted upon by the teeth on wheel 40, or in the position
of the parts shown in Figure 1. As soon as the dog 30 is carried upwards by the.
wheel 10, the levers 35 and 37 are brought into a horizontal position Figure 7. The
end of the hammer rod 38 is thus moved to the right of Figure 4, and inasmuch as
said rod is pivoted at 47, its upper end which carries the hammer 18 is brought into
contact with one of the type. How this hammer operates in connection with the
type, will be described further on. As the wheel 40 acting upon the toe 39 carries
up the dog 30, said dog travels up to the upper arch of the cam groove 32, and as
soon as it reaches this point, it is carried over said arch by the action of the
spring 35, and then the dog descends by gravity its roller following the opposite
side of cam groove 32, and thus reaches its normal position.
It will be seen, therefore, that the effect of pressing the key 4, is first to cause the
plate 15 to oscillate or swing. on its central pivot, and that the extent of this
oscillation will depend upon the position of the key nearer to or further from the
central pivot of the plate. That then as the key is pressed down, it throws the
toe 39 of the dog 30 into position to be acted upon by the always revolving
wheel 10, and that when the dog is thus acted upon, it acts upon the hammer
carrying lever 38, to cause the hammer 48 to make its stroke. It will be plain

page_text: that only one tooth of the wheel 40 can act upon the dog, because the dog having
been once lifted is immediately retracted by the spring 35, and does not again
assume a position in which it can be again moved by a tooth of wheel 40, unless
a key be operated in the manner described, to throw it into the proper situation.
I have already referred to the projection or pin 13 projecting downward from the
keys 4 and 65. This pin, when the key 4 (or 65) is pressed down, enters a hole
(one of a series) in the plate 15, which is suitably disposed to receive it, as shown
in Figure 4. But it does not reach this hole until after the plate 15 has been
moved by the projection 12. Of course, when the pin 13 enters the hole in
plate 15, plate 15 can no longer oscillate on its pivot.
And therefore the object of the pin 13 is to prevent too much accidental
motion of the plate 15. This might occur if a key were pushed down too suddenly,
so that the plate 15 might, in that case, swing a little beyond the proper point.
If as soon as the plate 15 is adjusted, the pin 13 enters the opening and locks it,
it will be obvious that no further motion of the plate 15 can ensue.
1 will now refer to the type mechanism. Extending up from the bed I, is a
tube 49 and surrounding this is a loose tube or sleeve 56. Upon said tube 50, is a
chain or sprocket wheel 51. The sprocket chain, dotted lines, 52 passes over fixed
pulleys 53, (Fig. 13 and dotted lines Fig. 2.) and is connected to the ends of the
swinging bar 15, by means of a screw bolt 53, as shown in Fig. 18. In order to
prevent slaking of the chain when the bar 15 oscillates I provide an are-shaped
plate 54, which is carried by said plate 15, by downwardly depending arms 55,
Figure 17. This curved bar 54 rests upon a roller 56, which is supported on the
bed I. The ends of the chain, after passing around the pulleys 53 extend over the
periphery of this curved bar to the end of bar 15. It will be understood, therefore,
that when the bar 15 is oscillated on its central pivot, it rotates the sleeve 50, and
that the extent of rotation of the sleeve 50 will be in either direction proportional to
the arc swung over by the bar 15.
57 is the type cylinder shown in partial horizontal section in Figure 11 and in
elevation Figure 12. This consists of an annular piece of metal or hard rubber
provided with tiers of compartments regularly arranged. I here show six of such
tiers A, B, C, D, E, F, Figure 4. Each tier contains fourteen type chambers. Each
chamber is of suitable size to contain one type 58, Figure 10. On each type is
formed a shoulder 61 of suitable size nearly to fill up the cross section of this
compartment and to move freely therein. The inner end of the type projects through
an opening in the rear of the compartment and into the central space 59. On the
outer periphery of the type cylinder 57 are formed transverse recesses to receive
plates 60 of metal, which extend in front of the type compartments. The outer ends
of the types pass through said plates as shown in Figure 11. Surrounding each
type and interposed between its shoulder and strip 60 is a spiral spring 62.
shown in Figure 4 the cylinder 57 is so disposed that the hammer 48 may act on the
lower tier of type. Extending downward from the type cylinder 57 is a sleeve 68
which fits over the tube 50, and this sleeve is shown in Figure 4, in its highest
position upon said tube 50. When said sleeve 63 reaches its lowest position, it
rests upon the ring or collar 64 as shown in Figure 1. It will be apparent, therefore,
that by raising and lowering the sleeve 63 and hence the type cylinder 57 vertically
upon the tube 50, I may bring either one of the different tiers of type A, B, C, D, E, F,
into position to be struck by the hammer 48.
As
Returning now to Figure 1 the type cylinder shown at 57 as has already been
stated, is in its lowest position, and the hammer 48 will operate upon the type in
the tier marked A. And it is to be understood that for the purpose of operating
these type in tier A, the keys marked 4 only are to be used. I have shown but
14 type in the tier A and hence, in order to make use of the entire alphabet, it will be
necessary to use the type in the next following tier, as B. For this purpose I use
the set of keys marked 65, which are also pivoted on the fulcrum bar 3, and which
alternate with the keys 4. These keys are constructed in a precisely similar manner

page_text: to the keys 4, that is, they have the downward projection 12 and cam 13, which acts
upon the pivot plate 15 but they extend further to the rear than do keys 4.
Extending downward from the upper case 7 is a bracket 66 Figure 4, to which is
pivoted a swinging bail 67 which extends over the ends of the keys 4 and 65. By
pressing any one of these keys 4 or 65 therefore the bail 67 may be swung on its pivot.
Connected with said bail is a rod GS which is pivoted to the lever 69, which works the
spacing mechanisin. Said spacing mechanism will be more particularly referred to
further on.
Also depending from the inner side of the case 7, is a bracket 70, to which
is pivoted two swinging bails 71 and 72. On the bracket 70 is a fixed stop 73 and on
the bail 71 is a toe or shoulder 74 which meets the stop 73, and in this way the
bail 71 is prevented from falling below the horizontal position. On the bail 71 is a
stop 75, which stop is met by the swinging bail 72, so that the upward motion of said
bail is thus limited. In the transverse portion of the bail 71, is arranged a latch 76.
which is connected by a link 77 with the bail 72. The keys 65 extend under and act
upon the bail 72. The keys 4 do not. Extending from the sleeve 63 is a yoke 78
to which is secured an arm 78* which carries a vertical rack 79. This rack passes
up through a tube 80, and has side projections 81, which pass through slots 82 in
said tube. Said tube is supported from the upper case 7.
Secured to rod 68, is a spring toe or stop 83, which acts upon the pivoted bell-
crank-lever 84, and the lever 84, operates the sliding spring bolts 85. In the-
sleeve 50 is a slot which receives said bolt, so that when the bolt is in the slot, the
sleeve 50 is locked and prevented from turning.
I will now describe the operation of the above set forth mechanism, the parts
being assumed to be in the position indicated in Figure I.
When either a key 4 or
a key 65 is pressed down, the bail 67 is raised, the rod 68 is thus pulled, the bell
crank lever 84 turned, and the bolt 85 drawn out of the sleeve 50; so that said
sleeve, and hence the type cylinder 57 is rendered free to turn. If one of the keys 4
only be operated, then the result already described as following the operation of that
key will take place, that is to say, the plate 15 will be swung and a type belonging
to the uppermost tier A will be put in place in front of the hammer, and the
hammer will be operated to cause it to strike the rear end of said type. If, however,
a koy 65 be pressed, then the rear end of that key will act upon both the bails 67
and 72. By reason of its action upon the bail 67, it will unlock the type cylinder in
the manner just described. By reason of its action on the bail 72. it will throw out
the bolt 76, and then when the bail 72 meets the stop 75, the rear end of the key
continuing its upper movement it will raise the bail 71. But the throwing out of
the bolt 76, has brought said bolt into engagement with the rack 79; and hence
when the bail 71 is lifted, the rack 79 is lifted with it; and as the rack 79 is
connected to the sleeve 63, that sleeve, and hence the type cylinder 57, is carried to
such a distance as will bring the second tier of type B in front of the hammer. The
projection 12 on the keys 65, then acts upon the plate 15, to rotate the cylinder, so
as to bring the type corresponding to the key in front of the hammer, and also to
cause the hammer to strike in the manner already described, in connection with
keys 4.
It will, therefore, be understood, that, for example, the keys 4 will be used to
print the first 14 letters of the alphabet, and the keys 65 to print the remaining
letters; and that when the keys 4 are touched, no vertical displacement of the
cylinder 57 will ensue; and that when the keys 65 are operated, they not only
control the striking mechanism, and set the cylinder, but also raise the cylinder a
distance equal to that between two tiers of type, and in this way bring the second
tier B, of type, into position in front of the hammer.
I will now describe the devices for setting the type cylinder 57 so as to bring into
position other tiers of type, as C, D, E, F. "Pivoted to the case 7, at 86, Figure 4, is.
a single key 87, the rear end of which extends to one side of the tube 80, and beneath
the projection 81 on the rack 79. Pivoted at 88 in said case 7, is another single
key 89, which extends under the projection 81, extending through the slot on the

page_text: other side of the tube 80, Figure 16. As the length of the key 87, from its real
extremity to its pivot 86, is much greater than the length of the key 89, from its
extremity to its pivot 88, it will be obvious that when the key 87 is pressed down, the
rack 79 will be lifted a much greater distance than when the key 89 is pressed down.
Now the length of the key 87 is so arranged that when said key is pressed down, it
will raise the rack 79, and hence the cylinder 57 a distance equal to that between
tiers A and B of the type. If, on the other hand, the key 89 is pressed down, this
will raise said cylinder 57 a distance equal to that between tiers A and C of the type.
Consequently, supposing the parts to be in the position shown at Figure 1, and it is
desired to bring the cylinder in such position as that the hammer 48 will act on the
lowest tier of type F, as shown in figure 4; key 87 would then be pressed down, and
in this way, the tier E of type would be brought opposite the hammer. Key 87 would
then be locked automatically in place by the spring 90 slipping over the projection on
the upper end of the curve of the guide bar 91, which bar extends down from the
key through the upper part of the case 6. Key 87 is thus held in place, and the
operator would then press key 65, which, acting on bail 71 in the manner already
described, would first raise the type cylinder 57, for a distance equal to that between
the tiers of type E and F, and in this way, the tier F would be brought opposite the
hammer, as shown in Figure 4. The rack 79 would then be supported by the
latch 76, and the projection 81 on said rack would necessarily be above and out of
contact with the end of the key 87.
It will be readily understood, without further explanation, how, by suitable
manipulations of the keys 87, and 89, and then of the keys 65 or 4, any of the
tiers A, B, C, D, E and F of type, may be brought into position to be acted on by
the hammer 48.
I will now describe the mechanism for moving the paper or other material upon
which the type are to produce their indentations. This is done by means of the
lever 69, which, as already described, is operated by the rod 68 secured to the bail 67,
which bail, it should be remembered, is moved by all of the keys 65 and 4. The
rod 69 is pivoted to the bracket 33 at 92*. The end of the rod 69 is forked and in
the fork is received the lower extremity of a bar 91, Figure 3. Upon one side of said
bar are formed rack teeth Figure 5, which engage with a pinion 95, which is supported
on the rear side of the carriage 96 in a bracket 97, (see Figures 1, 3 and 5). 98 is
the pinion shaft which terminates in a gear 99, this gear being placed just inside the
rear face of the supporting carriage 96, Figure 1. Surrounding said pinion shaft is
a spring which acts upon a fixed abutment on the bracket 97, and also on the pinion
shait is a ratchet 100 (dotted lines Figure 5) which acts upon a pawl 101, which pawl
acts upon the pinion 95.
The operation of this spring is to cause the pinion normally to turn in one direction.
102 is a bent bar also having on its edge rack teeth adapted to engage with pinion 95,
and provided on its horizontal portion with two rollers 103 on opposite sides of the
bar 94.
The bar 102 is pivoted at 104. Extending downward from the upper flange
of the carriage 96, are two bracket 105 and 106 to which are pivoted
levers 107, 108, which carry at their ends rollers which bear against opposite
sides of tho bar 94. The spiral spring 110 extends from the pivoted lever 108,
to the hook end of the bracket 106. A similar spiral spring 109 extends from
the pivoted lever 107 to the upper flange of the carriage 96. As the rod 94 moves
downward the tendency of the lever 108 acted upon by spring 110, is to crowd
the rod 94 against the pinion 95 and so cause engagement of the rack teeth of
rod 94, with the teeth of pinion 95, and simultaneously it moves rod 102 so as to
throw that rod to the left and out of engagement with the pinion. At the same
time lever 107 drops down (see Figure 5) and allows of this inward swing of rod 94
(in direction of the arrow) Figure 3. Then as the rod 94 continues its downward
motion, it rotates the pinion 95, and is assisted by the action of the spring on the
pinion shaft. On the upward motion of the rod 94, the levers 107 and 108 assume

page_text: the positions shown in Figure 3, and the rod 94 moves away from the pinion 95. At
the same time, the rod 94 draws the rod 102 into engagement with the pinion and
thus the pinion is locked in place until the rod 94 makes another down stroke, when
the foregoing operation is repeated. The carriage 96 is provided with a dovetail
slide 111, which enters ways 112 on the bed or table 1. Extending upward from
said carriage is a fixed nut 113, Figure 1. Also extending upward from the table 1,
are brackets 114, in which brackets is journalled a screw 115, which is turned by
the hand wheel 116. By turning the hand wheel 116, the carriage 96 may be caused
to slide in its ways, and so brought nearer to or further from the type cylinder 57.
On top of the brackets 114, is fastened a fixed pointer 117, and I may lay off the rim
of the hand wheel 116 in any convenient divisions, so that the pointer 117 will show
the extent to which the wheel has been turned, and thus the extent of the movement,
of the carriage may be nicely graduated and observed.
I will now describe the device which holds the paper or other material upon which
the type are to produce their impressions. The front view of this device is shown in
Figure 14. 118, 119, 120, are the vertical members and transverse members of a
frame of light, thin metal such as steel. In the lower portion of this frame is
journalled a roller 121. About half way up said frame is the rack bar 122, and finally
on the upper end of the members 118, 119, is journalled another roller 128, which is
supported in brackets 124. Between the rear end of the brackets 124 extends a
bar 125, Figure 3, and depending from this bar is a small bracket 126, which carries
a roller 127. The roller 127 runs on a rail 125 on the upper surface of the carriage 96.
On the lower front side of the carriage 96 is arranged a small horizontal roller 129,
against which the lower member 120 of the paper frame bears.
It will be understood therefore, that the paper frame is held between the roller 129
and the carriage 96, and that is supported upon the roller 127, which rests upon the
rail 128. The roller 121 enters and freely moves in a circular chamber 130 in the
carriage 96. The rack bar 122 enters and freely moves in a similar but smaller chamber
181 extending across the face of the carriage 96. Therefore, the frame 118, 119, 120,
is free to slide longitudinally crosswise the face of the carriage 96. The enclosing
wall of the chamber 131, which receives the rack bar 122, is slotted on its under side,
so that the pinion 99 may project therein, and engage with the rack bar 122.
A handle or hob 132 is provided for convenience in turning, the roller 123.
The spacing key 133 Figure 2, is a single lever not provided with the downward
projection 12. It is pivoted upon the bar 3. Its rear end acts upon the bail 67 to
raise the rod 68, and thus through the lever 69 to operate the bar 91 in the manner
already described.
Referring to Figures 1 and 4, beneath the projections 12 on the keys 65 and 1, is
disposed a curved bar 134, which is supported upon two bent rods, one of which
is shown at 135, which extends down between two fixed rollers 136, and is pivoted to
the bar 23 at 187. On the projection 12 of the keys 4 and 65, is a hook or shouldered
portion 138. When a key is raised as shown in Figure 1, the bar 134 stands partly
under the bar 21: but when the key is depressed, the effect of the rollers 136 upon
the bent rod 135, to move the bar 134 to the left of the drawing, so that the
hook 138 on the key engages with said bar 134, as shown in Figure 4. By this
time, however, the wheel 40 is acting on the dog 30, and hence the power from said
wheel is communicated along the lever 25, 24, to draw down the bent rod 135 still
further, and thus to ensure the upward movement of the rear ends of the keys 65 and 4
sufficiently to move the bails upon which they act to the full necessary upward extent.
The operator, therefore, has only to press down a key sufficiently to cause this locking
of the hook 135 and bar 134, and the motor driving the machine does the rest of the
work. In this way, the manual labor of operating the keys is greatly diminished.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed
First. A machine for producing indented type-impressions embodying the

page_text: combination of a type longitudinally movable in its support, a hammer in rear of the
type and mechanism manually controlled for actuating said hammer to press the face
of said type into the indentable material.
Second. A machine for producing indented type-impressions embodying the com-
bination of a type longitudinally movable in its support, a hammer in rear of the
type, mechanism manually controlled for actuating said hammer. to press the face of
said type into the indentable material, and mechanism manually controlled for moving
the type into and out of the path of the hammer.
Third. A machine for producing indented "type-impressions embodying the com-
bination of a type longitudinally movable in its support, a hammer in rear of the
type, mechanism manually controlled for actuating said hammer to press the face of
said type into the indentable material and mechanism manually controlled for moving
the indentable material in front of the type.
Fourth. In combination with mechanism substantially as hereinbefore described
for pressing the face of a type into a body of indentable material for moving said body
of indentable material in front of the type and for substituting one type for another
in the path of the pressing device, a motor actuating said mechanism and finger keys
or analogous means for controlling said mechanism and bringing the motor into
operation to actuate the same.
Fifth. In the machine herein before described, the annular rotary support for the
type and the hammer arranged within said support and acting upon the type to press
it into the indentable material.
Sixth. The combination of the pivoted plate 15, the key 4 having a cam projection
acting upon and vibrating said plate when said body is depressed the rotary type
carrying cylinder 57 and gearing between said plate and said cylinder for transmitting
the notion of said plate to said cylinder.
Seventh. The construction and arrangement of the pivoted plate 15 provided with
springs for returning it to its normal position after displacement, the key 4 provided
with a cam projection for vibrating said plate when the key is depressed, and with a
locking device for holding said plate in position when moved by the key, and the
gearing for transmitting the motion of the plate 15 to the said cylinder.
Eighth. The mechanism substantially as described for transmitting motion from a
imotor through the spur-wheel 40 to the hammer.
Ninth. The mechanisin substantially as described for transmitting motion from a
motor through the spur wheel 40 to the cylinder rotating devices.
Tenth. The mechanism substantially as described for transmitting motion from a
motor through the spur wheel 40 to the carriage whereon the material to be impressed
is supported.
Eleventh. The construction and arrangement of the carriage supporting the material
to be impressed.
Twelfth. A machine for producing indented type-impressions embodying the com-
bination of a type longitudinally movable in its support, a hammer in rear of said
type, and operating to press said type into said body of indentable material, and
mechanism for moving said type laterally in two directions relatively at an angle into
and out of the path of said hammer or over the surface of the body of indentable
material.
Thirteenth. The construction and arrangement of the type supporting rotary
cylinder having two or more tiers of type, the hammer moving within said cylinder
and the mechanism for moving the type in any given tier into and out of the path of
the hammer.
Fourteenth. The mechanism substantially as described for controlling the vertical
position of the type supporting cylinder by means of the finger keys.
Fifteenth. The mechanism substantially as described for transmitting motion from
a motor through the spur wheel 40 to the type-supporting cylinder to elevate or lower
the same with reference to the hammer.
Sixteenth. The construction and arrangement of the machine hereinbefore described,

page_text: whereby the manipulation of finger keys by an operator throws a motor into con-
junction with mechanism for placing a given type in the path of a hammer by
rotating or raising or lowering the type support in front of said hammer, actuates
said hammer to press the type face into a body of indentable material and also moves
said body of indentable material laterally in front of the type.
