An Improved Method of and Apparatus for Locking Printers'
Forms in Chases and Galleys.
I, FREDERICK CLARK, of 83, Cheeschill Street, Winchester, in the County of
Hampshire, Compositor, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
My invention relates to an improved device or apparatus for locking up forms
of printers type in chases or galleys, and has for its object to supersede the present
method of effecting such locking by the use of wedge shaped pieces of wood
technically known as "quoins,"--and to provide a means whereby such locking
up and unlocking may be effected with greater expedition, certainty and accuracy
than obtains with the use of such quoins, and other expensive and cumbersome
devices hitherto made and used.
In order that my said invention and the alternative methods of constructing
the same, and the manner of its use may be fully understood, I have hereunto
appended a sheet of drawings, of which,
Figs. 1 and 2 are perspective views of the two plates or parts which (according
to one method of construction) constitute the apparatus forming the subject of
my invention.
Figs. 3 and 4 are front or end view and central section respectively of the
form of nut, used in connection with Figs. 1 and 2, the latter being a section
upon the line A B of the former.
Fig. 5 is a plan view of the complete apparatus, or in other words Figs. 1 and 2
coupled together by the nut Figs. 3 and 4.
Figs. 6 and 7 are views similar to Figs. 1 and 2, but illustrating an alternative
method of construction, while Fig. 8 is an enlarged central sectional view of the
nut employed in this device, also illustrating as an example, the manner in
which I prefer to connect the said nut with the plate Fig. 6.
Fig. 9 is a view of a printers chase, which by the aid of the explanation herein-
after contained, will serve to make clear the application and use of my invention
in connection therewith and printers galleys.
According to the method of construction illustrated by Figs. 1, 2, 3, 4 and 5
my invention consists of a pair of metallic plates A and B, each of which has
upon its inner face a threaded stud marked respectively C and D, the one C hav-
ing a left, and the one D a right handed thread, the dimensions of the said plates
and the length of their respective studs varying according to the size of the
chase or galley, with which they are to be used, and the dimensions of the set up
matter or form to be locked thereby, but whatever may be the length of the said
studs C and D a proportionately sized nut E would be provided, formed exter-
nally to receive a spanner, and internally with a right and left handed thread,
as at Figs. 3 and 4, adapted to engage with both the studs C and D, so that when
rotated in one direction, the plates A and B may be brought as near together as

page_text: the length of the nut E will permit, and when rotated in the opposite direction
separated as far as the length of the said studs will permit without being dis-
engaged from the said nut, as illustrated by full and dotted outline in Fig. 5.
According to the method of construction illustrated by Figs. 6, 7 and 8, the
plate B only has such a stud D, which may have a right or left handed thread
formed thereon, preferably the former, while the plate A has a nut F mounted
thereon in such a manner as to be capable of rotating about a centre provided
upon the said plate, which I may attain by various means, but for preference, I
fix upon or form integrally with the said plate A a boss G, the nut F being formed
with one end blocked, in which a hole is formed capable of engaging with, and
permitting the nut F to rotate about the said boss, the said nut being retained
thereon by a broad headed screw or bolt such as H, adapted to engage with a
threaded hole formed in the boss G and the plate A as illustrated by Fig. 8, the
said nut being formed externally to receive a spanner as shewn in Fig. 6, the said
plates being brought nearer to or farther from each other, in the manner illustrated
by Fig. 5, by the nut F being rotated so as to be screwed upon or off the stud D.
Whichever method of construction I may employ the manner of their opera-
tion is substantially the same, that is to say, the form or matter J when set up
and placed within the galley or chase K, and surrounded by parallel side sticks L
in the usual way, such spaces as may exist between the said side sticks and the
galley or chase K, would be occupied by any suitable number of one or the other
of the devices forming the subject of my invention, (as illustrated by Fig. 9)
instead of the wedge shaped wooden quoins or other devices hitherto employed
for locking the said set up matter J firmly in the chase or galley K. In Fig. 9
the said devices according to my invention are shewn by the reference letter X,
and it will be understood that whichever method of constructing my invention
may be employed, the rotation of the connecting nut E or F in a direction capable
of separating the plates A and B, would serve to lock up the said set up matter J,
the said plates being at all times perfectly parallel with each other, the evenness of
the work or pressure given off from each device being easily ascertained by
testing the tightness of their respective nuts, and the forms or matter J so locked
up according to my invention will remain so for any length of time if desired,
and will not become loose as obtains with the use of wooden quoins when exposed
to a dry heat, and when required for distribution the set up matter may be
instantly released by the mere unscrewing of the nuts For E from their respec-
tive studs D, or C and D as the case may be.
1. 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:
_
1st. The herein described method of locking printers set up matter or forms
in chases or galleys, by the means of any number of pairs of plates, each pair
being arranged to be brought nearer to or farther from each other by the mere
rotation of a connecting nut, substantially as herein set forth and shewn by the
appended drawings.
2nd, In a device for locking printers set up matter or forms in chases or
galleys, the combination of a pair of plates such as A and B, having projecting
studs C and D, provided with left and right hand threads respectively, with nut
such as E adapted to engage with both C and D, substantially as herein described
and shewn by Figs. 1, 2, 3, 4, and 5 of the accompanying drawings.
3rd. In a device for locking printers set up matter or forms in in chases or galleys,
the combination of a pair of plates such as A and B, the latter having a threaded
stud such as D, and the former a nut such as F, adapted to rotate upon a boss
such as G fixed upon or formed integrally with A, and having an internal screw
thread adapted to make contact with the threaded stud D, substantially as herein
described as shewn by Figs. 6, 7 and 8 of the accompanying drawings.
4th. The locking devices characterized by the preceding claims, and the use

page_text: and application of the same substantially as and for the purposes herein described,
and shewn by Fig. 9 of the appended drawings.
