Improvements in Linotype Macnines.
THOMAS PURVIS RITZEMA, Quarry Glen, Blackburn, Newspaper Proprietor, do
hereby declare the nature of this invention to be as follows:-
Application of tension to keep securely in position the assembly lid of linotype
machines with automatic action to provide for wear and tear. Hitherto the lid
or door of the assembly boxes of linotype machines have been kept secure by a
spring, which in actual operation cut the sides of the lid away, and ceased to act.
I attach an automatic catch, with adjustments to provide for wear and tear, so
as always to keep the assembly lid in position.

Improvements in Linotype Machines.
I, THOMAS PURVIS RITZEMA, of Quarry Glen, Blackburn, in the County of Lan-
caster, Newspaper Proprietor, 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:-
This invention relates to improvements in the method of and means employed
for automatically holding the lid of the assembly box in linotype machines, the
object being to provide against wear and tear of the parts and to dispense with the
spring heretofore employed and which when in operation had a tendancy to cut
and wear away the side of the lid, and consequently soon required renewing.
Such being the nature and object of my said invention, the following is a com-
plete description of same, reference being had to the annexed drawings, in
which:-
Fig. 1 is a front elevation of part of the assembly box of a linotype machine
shewing the improved appliances for holding the lid in position.
Fig. 2 is a sectional end elevation of Fig. 1.
According to this invention the assembly box 1 is made in the usual manner
and the lid 2 is hinged thereto as ordinary. To the front of the box 1 is fixed
a hollow bracket or spindle 3 with a projection or lug 4 forming part of it, and
this projection or lug 4 serves as a means for fixing the bracket 3 to the box 1
by means of the screw 5, and also acts as a stop piece for preventing the lid 2
moving beyond a certain point when opened as the hinge arm 6 of the lid 2
comes into contact with such stop piece 4. Inside the bracket or spindle 3 is a

page_text: spindle 7, the upper portion being of larger diameter than the lower, and terminat-
ing in a button 8 protruding from the bracket 3, whilst the lower end is chased
or threaded and its protruding end provided with a nut 9 outside the bracket 3.
Coiled around the spindle 7 and between the shoulder 10 on the latter and the
bottom of the bracket 3, is a spiral spring 11 which tends to force the spindle 7
outwards. On the lid 2 of the box 1 and directly above the button 8 is fixed an
inclined block 12, with a flat portion 14.
When the lid 2 is moved above its box 1 the inclined block 12 comes into con-
tact with the button 8, compresses the spring 11, and the pressure of the latter
then presses the button 8 against the flat surface 14 and holds the lid in position.
The nut 9 provides a means of adjusting the pressure of the spring 11 to the
required degree.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is―
(1) The general construction, arrangement, and combination of parts con-
stituting the improved means for holding the lid of the assembly box of linotype
machines, as herein described and substantially as illustrated by the accompanying
drawings.
(2) In linotype machines the use in combination with the assembly box of a
button headed spindle forced outwards by a spiral spring as to hear against an
inclined block on the lid of such assembly box substantially as herein described.
