PROVISIONAL SPECIFICATION.
A New or Improved Type-dressing Machine.
1 JULIUS BRÄUNIG of the firm of Kathe & Co. Machinery Manufacturers of Leipzig
in the Empire of Germany do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to construct a machine for removing burrs, fins or
roughness etc. from printing type.
The nature of the improved machine is as follows:
The separate types are placed upon an endless band and moved thereby in front of
a reciprocally sliding rod driven by power, which abuts against the type and drives it
laterally into a passage way in the upper and lower faces or walls of which are suitable
knives by which the type is shaved upon its uppermost and lowermost lying faces
respectively. In front of the said type is another reciprocally sliding rod, which is
drawn by a weight to abut against the front of the type and hold it securely against
the end of the driving rod aforesaid. This second rod, which may be called a counter
rod, retreats with the type, until the latter, having been dressed as aforesaid, arrives at
the termination of the passage way. At this point the drive rod, will by suitable lever
gear, have caused a lever to be released so that said lever having an inclined face
arrives and bears upon an inclined face on the counter drive rod, and thereby causes it
to be moved slightly away from the type so that the latter ceases to be gripped
between the drive rod and the counter rod and is free to fall along an inclined chute
into a second passage way, where there is a similar drive rod and counter rod and
knives for dressing the upper and lower lying faces of the type which faces, by the
manner in which the chute etc. is arranged, will now be those which in the first.
passage were the faces gripped between the drive rod and counter rod. The end of
the type, will be dressed by a special knife in one or other of said passage ways or
elsewhere in the track pursued by the type.
The type having passed the second passage and been released in the same manner
as aforesaid falls through a second chute onto a track along which a third drive rod
may in due course push the type out of the machine.
The passage ways may be formed between blocks supported on suitable standards,
the upper one adjustably to be arranged according to the thickness of the type being
dressed.
The drive rods may be fixed upon bars guided in parallel shears fixed on a vertical
frame, the counter rods in a similar manner upon another vertical frame. The drive
rods may be moved by crank rods from wrist pins upon wheels revolving on
gudgeons one above the other and toothed to be driven by spur gear. The wrist pins
are so placed that the movements of the successive drive rods are alternate.
The lever gear aforesaid by which the counter rods are moved from the type at a
certain time may consist in the following ;—a pawl is pivoted to the framework at a
suitable place, and is controlled by a spring so that an inclined face thereof acts on
an inclined face on the counter rod arrived thereunder in manner and to the purpose
before mentioned when the pawl is released from the disturbing pressure of a bell
crank lever, one arm of which is connected by a rod to a pin guided in a slot in
the drive rod. The bell crank lever is moved to allow the pawl to act when the
drive rod has moved sufficiently far that the said pin is likewise moved by arriving
at the end of said slot.

In the drawings hereto annexed.

Fig. 3 is a section on line A B Figs. 1 and 2.
Fig. 4 is a section on line C D, and
Fig. 5 is a side elevation of the knife frame.
The operative parts of the machine consist mainly of the longitudinally reciprocating
sliding rod m which is guided by means of the sliding block in the standard
fastened to the foundation plate g', of the counter rod a movable in the saine direction
and arranged to move automatically towards the rod m said counter rod being
guided by the adjustable rest of the sliding rod m³ moving in a plane at right
angles to that of the sliding rod m and which is guided by means of the sliding
block in the standard fastened to the foundation plate g', of the parts o, o' and
provided with saw shaped knives said parts being supported at the standard 0
fastened to the foundation plate q'; of the knife a on standard wand of the endless
band u. carried around the rollers a' and a².
As shown by Fig. 1 two knives c touching one another at right angles are
arranged on the part o and opposite to these respectively are a knife c³ on part o¹
and a knife con part r so that the working planes of each pair of knives touch one
another at right angles and consequently that the types a¹ have to pass those working
surfaces are dressed on all four sides.
For the purpose of adjusting the distance of the knives e according to the thickness
and width of the types to be dressed, the parts o' and r (see Figs. 2 and 4) are each
adjustable by set screws which are journalled to turn in plates a³ fastened to the
standard w, said parts of and r being tapped with female scrows for the screws
so that said parts are drawn towards or from the plate a*. The counter rod n which
is connected with the weight pt by the cord running over the roller v, and is thus
drawn towards the rod m serves also to arrest the types a deposited on the band u
and moving with the latter, and is adjustable on the frame on the standard t in
such a manner that the stop device on the said counter rod n may be adjusted
according to the length of the types to be dressed.
The knife on standard w is adjustably arranged with its bearing block u' to
move sideways on a prismatic guide being controlled by the screw and also to move
lengthways on the block u' under control of serow for the purpose of adjusting said
knife backwards and forwards always to the centre of the surface to be dressed
for the dressing of types of different widths.
The machine is driven by power applied to the shaft and the sliding block
with the rod m is reciprocated by the action of the connecting rod d joining said
block to a wrist pin eccentrically placed on the wheel on said shaft. The rod m
is reciprocated by the rod d, bell crank lever and adjustable connecting rod d
engaging on a wrist pin eccentrically placed on wheel gearing with the wheel
aforesaid. The requisite time movement of the rod m' is provided for by the con
nection of the rod d' with the lever by means of a pin and slot go. The band u is
moved by the bevelled gear o³, driving shaft d', the gear o connecting the latter to
the shaft d which carries one of the belt pulleys a³.

page_text: To dress types by this machine they are placed in a row on the band u over the
roller a', end to end, with the face towards the stop device c. The band carries
along the type until it arrives in front of the slide rod m touchos the stop
device .
From there the slide rod m takes up the type and carries it touching against
the counter rod n, therefore gripped between the slide rod m and the counter
rod n and pushes it between the knives 3 fastened to the parts o and o¹. During
this movement of the slide rod m towards the slide rod m¹ the connecting rod d¹
moved by the wheel slides with its longitudinal slot upon the bolt 9 and as soon
as the slide rod m reaches the end of its stroke and has carried along the type .r¹
through the first pair of knives over the space formed by the working surfaces of the
second pair of knives the end of the longitudinal slot in the connecting rod d¹ touches
the bolt so that the bell crank lever is turned, the sliding block is drawn
down by the connecting rod d³ and the sliding rod m' is moved between the knives c³
fastened to the parts o and r. In this manner the sliding rod m¹ removes the type
gripped by the slide rod m and the counter rod n and pushes it between the second
pair of knives during which the slide rod m is withdrawn by the connecting
rod d.
During the motion of the types through the second pair of knives it is properly
dressed on the remaining two longitudinal surfaces and the end surface is shaved
also by the knife (Figs. 2, 4 and 5).
The sliding rod m³ and sliding block is pressed back again by the spring f
pressing against the latter between the second pair of knives after its final motion so
that the counter rod n is liberated and follows the slide rod m by the influence of the
weight p'. After the slide rods m m¹ and the counter rod n have returned to their
original position the band u moves another type in front of the slide rod m and the
movements are repeated in the same manner, the dressed type being gradually pushed
out of the chute p.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
