page_text: 1, JOHN RAPHAEL KOGERS, of Detroit, in the County of Wayne and State of
Michigan, United States of America, Inventor, 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 invention consists in an improvement in machines for making printing
surfaces, hereinafter fully described.
Figure 1 is a top plan view.
Figure 2 is a rear elevation;
Figure 3 a side elevation, of the storage point, partly in section ;
Figures 4 and 5, side elevations of part of the carrying mechanism ;
Figure 6, a transverse vertical section, and
Figure 7 a longitudinal vertical section through the assembling point;
Figures 8 and 9, views similar to Figures 6 and 7;
Figure 10, a section through part of the storage mechanism, and
Figure 11 a side view, Figures 6 and 7 showing one form of track, Figures 8
and 9 another form, and Figures 10 and 11 still another form.
My invention relates only to mechanism for assembling in line a series of dies,
from which either a cast may be made or an impression in soft metal taken, and has
nothing whatever to do, either with the casting operation or the impression operation,
so that the drawings only show, and the descriptions only relate to, the mechanism
for assemblage and distribution.
A and A represent two skeleton frames, secured together at a certain distance
apart and which are, as shown in Figure 1, approximately the shape of a sector of
a circle. At the meeting point of the two radii or converging sides, these frames
are extended inward so as to form bearings for the pintles of the four grooved
pulleys, B2, B3, B1 and B. In the outer corners of the frames are pivoted grooved
pulleys B and B7, and each of these pulleys has one half as many grooves as there
are to be characters used in the machine.
B and B represent grooved idler pulleys journalled in the rear of the frames A
aud A, simply to serve as guides for a portion of the belts, and these pulleys
need not have as many grooves as the others, and may be entirely dispensed with
by carrying the pulleys B and B farther back from the pulleys B³ and B*.
It will be noticed that the four pulleys B and B³ ou one side, and B and B on
the other side, are so placed as to inclose a parallelogram between them so that
all the belts running upon pulleys B and B will lie vertically one above the other,
077

page_text: and be parallel with the belts running over the pulleys B' and B, which also, between
these two pulleys, lie vertically one above the other.
Crepresents a frame which for compactness I make in the shape of a bow, but
inclined upward from both ends to its centre, its ends being secured to the frame A.
Of course, this frame C may be varied in shape, and may be horizontal, but it makes
a more compact machine, and makes all the belts more nearly equal in length
between the points of storage. and, of assemblage, to make. this frame C in the shape
indicated in the drawings, and for these reasons I prefer this shape, though it is not
an important feature of my invention.
c represents a series of small grooved pulleys, each of which is journalled on a piu
fastened in a plate M secured to frame C, and these plates M may be made adjustable,
for alignment.
NN represent endless belts which are distributed equally on the two sides
of the centre line running from the centre of the frame A through the centre of
the frame C. This is the best arrangement, but of course the equal distribution of
these belts on the two sides of the centre is a mere detail of construction, which may
be departed from.
All the belts on one side of the centre line, for example, at the right, Figure 1,
pass from their respective pulleys c to the grooves in the pulley B, thus covering
approximately half of a sector of a circle, then pass around pulley B³, around
pulley B', from which part of them lead directly to the small pulley c, while
the others pass around the idler pulley B, and thence to their respective pulleys c,
the idler being put in to distribute the belts to their respective pulleys without
crowding or interference, and the arrangement of the other half is exactly
similar.
E represents a shaft running under frame A' carrying at one end a belt pulley D,
and carrying two bevel gears e, which mesh with similar bevel gears d on the lower
end of the pintles of the pulleys B and B', so that when shaft E is rotated,
pulleys B and B are rotated at equal speed, but in opposite directions, and thereby
all the belts which pass over said pulleys B and B are set in motion. Shaft E is
journalled in brackets F, secured to frame A¹.
KK represent thin bars, each of which is formed at its upper end with an eye,
large enough to loosely embrace one of the belts N, and I prefer to make this eye
considerably larger in internal diameter than the belt. On one edge of each bar,
at the point R, is stamped a matrix or is formed a male die, this being indicated in
Figure 3 by the capital letter C, and in Figure 7 by a series of lower-case letters.
Of course the thickness of the bars K will vary with the characters carried
upon them, but all the bars K on any one belt N will carry the same character.
It is evident that when belt N passes through the eye of one of these bars K, and
the bar is left uncontrolled, it will hang on the belt, and if the belt is in motion,
will be carried by it, passing between pulleys B2 and B, then between pulleys B
and B, and out and back in one direction or the other around pulleys B¹ and B',
so that the bar will tend to describe this circuit, so long as the belt is in motion.
I therefore provide retaining and escape mechanism at that part of each belt near
frame C, so that the belt may rotate without carrying any of the bars, unless a
bar is freed by the escapement from the retaining mechanism, and I also provide
retaining and release mechanism in the parallelogram inclosed by the four
pulleys B, B, B' and B'.
P,
The retaining and escape mechanism substantially consists of a vertical shaft
journalled in a yoke P¹ fastened to frame C and encircled within said yoke by a
coil spring P holding it normally in a fixed position. Below yoke P¹, shaft p has
formed in one side of it a vertical groove a trifle larger than the rounded end of
one of the bars K, and on its upper end is provided with a crank h, to which is
adjustably secured one end of a rod H, the other end of which leads to a finger
key set in the key-board G, secured by lug g to frame A, the operation being that
when a finger key is depressed, rod H, through the medium of crank h, rotates

page_text: shaft against the resistance of the spring and the groove in said shaft moves
forward one of the bars K, as illustrated in Figure 3, and at the same time
prevents any of the other bars K from moving, and when the finger key is released
the spring P brings the rod p back to its normal position, ready to release
another bar.
The bars K are of different lengths, as shown in Figure 7, so that when a
number of them are assembled, the point R, at which the matrix or type is
carried, will be at about the same level, so that they may be aligned at exactly
the same level.
When a bar K is released by depressing its finger key, it is carried by the belt
by reason of the frictional contact toward the pulley B, or B, as the case may be,
and when it passes through the parallelogram inclosed by pulleys B2, B³, B₁
and B, it strikes against a lug l, carried on a vertically journalled crank
shaft L, and is checked, the next bar coming in being checked by the bar already
in position, and so on, until a line is assembled. When it is desired to distribute
said bars, they are released by moving the crank shaft I by hand, so as to draw
lug out of the path of the bars K when the belts carry all the bars back until
they are stopped by striking against their respective series of bars already held in
place by the escapement and retaining mechanism. If it be desirable, as will
often be the case, to make the, bars K longer than the distance between the belts
on which they are carried and frame A', said frame A' may be carried down at its
forward end, as shown at Y, Figures 6, 8 and 9, and these downward extensions
may carry a foot plate U. I represents a light iron frame extending around
frame A to guide the lower ends of the bars K, and prevent their being thrown
outwardly by centrifugal force, as they pass around the pulleys. It is supported
by brackets i, extending outwardly from brackets F. f represents bars carried on
the lower end of the brackets F, in which the pintles of the pulleys B and B' are
journalled. While said bars K may always hang on the belt N, I prefer, at the
points of storage and assemblage, to so support said bars that the belt N will run
through the eyes thereof without frictional contact, thus avoiding any undue wear
upon suid belt. This may be done by providing at those points a track upon
which said bars can rest, and I have illustrated in the drawings three forms
thereof.
In Figures 3, 6 and 7, these tracks consist of a light piece of sheet metal J or J1,
which in Figures and 7 are secured in an upright O, between frames A and A',
extending outwardly from said upright, then extending upwardly, and the upper
ends are curled over so as to pass around and nearly encircle a belt, and in this
form the eye of bar K cannot be entirely closed, though it may be so nearly
closed that the bar is still a "tied" matrix. As a bar K is carried along by its
belt N, it readily jumps on to its track J or J', and slides along said track until
it is stopped either by another bar or by some retaining mechanism, and at the
point of storage, in the form which I have chosen to illustrate my invention, this
track may be sufficiently inclined to insure the forward bar always lying against
shaft p.
A fine slot may be cut in the top of the tubular part of track J, so that
the belt will give the bars hanging on said track slight impulses.
In Figures 8 and 9, the tracks marked o are made of sheet metal shaped like a
gutter, and carried on uprights O, and the lower side of the eye of the bar K rests
in the gutter.
In Figures 10 and 11 the track is a bar o², supported by a hanger o from
frame Con which rests bar K, as shown in Figure 10. The track o' may be
slightly inclined as shown in Figure 11. When a series of matrices has been
assembled, and is to be distributed, if the track used is like that of Figure 7 it is
necessary after swinging crank shaft L to push the entire line of matrices off from
the track on to the belts which is done by a slight touch of the fingers, when they
are immediately carried around and distributed. With the other forms of tracks,
this is not necessary.

page_text: I have said nothing about spacers, and have shown no mechanism for assembling
them, but they may be of the double wedge type, and may be assembled at proper
spaces in the line, by any suitable mechanism. They may be assembled and
distributed by an endless belt as are the bars K, the movable wedge being provided
with a slot to permit its being forced upward.
While I very much prefer the arrangement which I have illustrated and
described, it is evident that the form of machine may be materially changed, that
the pulleys B, B³, B' and B' may be entirely omitted, and all the belts put on the
other pulleys, and it is also evident that idler pulleys may be put in at any desired
points to support the belts in their travel.
I believe that I am the first to combine "tied" bar carrying either a matrix or
type, with a continuously moving carrier, whose motion serves to both "assemble"
and distribute such bar, and that my invention covers this combination in any
and every form.
"
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is :-
1. In a machine for making printing surfaces, the combination with an endless
moving belt of a bar carrying a type or matrix loosely hung on said belt, aud
means for holding said bar stationary while the belt is in motion.
2. In a machine for making printing surfaces, the combination with an endless
moving belt of a bar carrying a type or matrix loosely hung on said belt, and
means for holding said bar stationary at either of two points, while said belt is in
motion.
3. In a machine for making printing surfaces, the combination with an endless
moving belt of a type or matrix bar hung loosely thereon, escape mechanism for
retaining or releasing said bar at one point of its travel, while the belt is in
motion, and retaining mechanism for arresting said bar when released, at another
point in its travel.
4. In a machine for making printing surfaces, the combination with a series of
endless moving belts which at one point of their travel lie in the same vertical
plane, of a series of type or matrix bars loosely hung on said belts, each bar on &
belt bearing the same character, escape mechanism operated by finger keys for
retaining and releasing the bars on each belt at one point of their travel, and
retaining mechanism for arresting all of said bars, when they arrive at said
vertical plane.
5. In a machine for making printing surfaces, the combination with a series of
endless moving belts of a series of type or matrix bars hung on said belts by eyes
of greater internal diameter than said belts, escape mechanism operated by a
finger key for each belt, at one point in its travel, a stationary track in advance
of said escape mechanism to hold said bars practically out of contact with said
belt, a stationary track for each belt at the point where said belts lie in a vertical
plane, and a single arresting and release mechanism for all of said belts at
said point.
6. In a machine for making printing surfaces, the combination with two series
of endless moving belts which in their passage toward the front of the machine
converge and lie in two vertical planes, of a series of type or matrix bars loosely
hung on said belts, the bars on each belt bearing the same character, a finger key
for each belt, and escape mechanism for each belt connected with its appropriate
finger key, and a common arresting mechanism for all the belts at the point where
they lie in two vertical planes.
7. In a machine for assembling matrices or type, the combination with an
endless moving carrier of a type or matrix bar permanently connected with said
carrier and means for arresting and holding said 'bar while said carrier continues
*its motion.

page_text: 8. The combination with an endless moving belt and a type or matrix bar carried
thereby, of a guard approximately parallel with said belt to counteract the effect of
centrifugal force on the lower end of said bar.
