HERMAN T. SUNDSTROM, OF HOUSTON, TEXAS.
LINOTYPE AND INTERTYPE.Specification of Letters Patent.
Patented Feb. 11, 1919.
Application filed September 25, 1917. Serial No. 193,070.
To all whom it may concern.
Be it known that I, HERMAN T. SUND-
STROM, a citizen of the United States, resid-
ing at Houston, in the county of Harris and
5 State of Texas, have invented certain new
and useful Improvements in Linotypes and
Intertypes, of which the following is a
specification. -
This invention relates to new and useful
10 improvements in a safety attachment for
linotypes.
The object of the invention is to provide
an attachment of the character described,
which will operate automatically to stop
15 the matrices in the intermediate channel,
and before they reach the mold disk, in case
they have been improperly assembled in the
assembling elevator. In operating a lino-
type, the matrices are first assembled in the
20 assembling elevator and some of these
matrices are capable of being assembled in
two positions, that is, in upper or lower posi-
tion. If the matrices are 14 point or
smaller, they should be assembled in lower
25 position so as to aline with the mold disk
when carried into position for casting. If
they do not aline with said disk, the casting
metal will not be projected directly against
said matrices, and an imperfect casting will
80 result; and furthermore the heated metal
will escape, causing what is known as "front
overflow" or "front squirt."
It is the object of this invention to pro-
vide an attachment of the character de-
85 scribed which will automatically stop the
matrices in the intermediate channel before
they reach the molding disk, in case they
have been assembled in the wrong position
in the assembling elevator and when the
40 matrices have been so stopped, they can be
then adjusted to lower position before they
are sent on through the intermediate chan-
nel to the molding disk of the linotype.
With the above and other objects in view,.
46 the invention has particular relation to cer-
tain novel features of construction, opera-
tion and arrangement of parts, an example
of which is described in this specification
and illustrated in the accompanying draw-
50 ings, wherein;
Figure 1, shows a side elevation of the
vise cap of a linotype, showing also the in-
termediate channel associated therewith.
Fig. 2, is a plan view thereof.
55 Fig. 3, is an end elevation, showing the
safety attachment in locked position.Fig. 4, is a fragmentary end view of the
delivery channel showing the safety attach-
ment in neutral position.
Fig. 5, shows an enlarged fragmentary 60
end view thereof, with the safety attach-
mert in active position.
Fig. 6,- shows an enlarged plan view of
the first elevator, filling piece, showing also
a fragmentary view of the safety attach- 65
ment.
Fig. 7, shows a fragmentary sectional
view of the vise cap, showing the safety
attachment in locked position, and
Fig. 8, is an enlarged view of the inter- 70
mediate channel showing the spring and
locking pin.
Referring now more particularly to the
drawings wherein like numerals of reference
designate similar parts in- each of the fig- 75
ures, the numeral 1, indicates the first ele-
vator filling piece, which is hinged to the
top of the vise cap 2 by means of the hinge
3. These parts are common to linotypes.
The matrices 4 are assembled in an as- 80
sembling elevator, the same being a well
known part of the linotype and conse-
quently not being shown in the drawings,
and from this elevator they travel along the
intermediate channel 13 on their way to the 95
mold disk. In case matrices of 14 points
or. less are assembled in upper position, in
the assembling elevator, they will not aline
with the mold disk and consequently, should
be adjusted before they reach said disk, so g0
as to come in perfect alinement therewith.
The vise cap 2 is provided with a. groove 3'
and extending laterally from the filling
.piece 1 is a U-shaped member 2' which rests
in said groove when said filling piece is in 05
active position.
Secured to the vise cap 2 and opposite the
exit end of the intermediate channel 13 is an
upstanding brace 7'. The upper and lower
ends of this brace have bearings, in which 100
the actuating rod 7 operates, the lower end
of said rod being turned laterally and form-
ing an arm 6, and the upper end thereof
being formed into a curved finger 8. One
of the channel rails of the intermediate chan- 105
nel 13 has a bearing 10', and also has a flat
spring 9 secured thereto at one end, the
other end of said spring carrying the pin
10 which projects into said bearing 10', but
normally does not project beyond the inner no
surface of said channel rail. When the fill-
ing piece 1 is thrown into active position,1,294,192.
