PROVISIONAL SPECIFICATION.
Improvements in or connected with Stereo Mounts or Beds with
Appliances for Fixing Stereo or other Plates thereon for Printing
Purposes.
I, ROBERT PURDY TICKLE, of 57 Achilles Road, West Hampstead, Middlesex,
Traveller, do hereby declare the nature of this invention to be as follows:-
This invention relates to novel construction, or arrangement of frame and special
appliances for locking stereo and other plates thereon, also for adjustment to suit
different sizes of plates.
For the purpose of my invention, I cast or otherwise form a frame with V, or
other shaped ribs on the inner faces or edges. The body of the frame is furnishe
with a series of strips, the ends of which are grooved to correspond to the ribs of the
frame. These ribs, or strips are preferably at an angle of 45°, so that they can be
moved along within the frame to suit the sizes and thickness of stereo, or other
plates to he laid upon them. Between and over these strips where the plates are
placed, lipped clipping pieces are arranged to fit over any of the ribs for binding
the plate or plates at the required position.
Two or more of the ribs are grooved longitudinally and are provided with screw
pins and nuts, which nuts can be turned to separate two adjoining ribs to put the
others into close contact and bind the strips firmly in position.
At two of the corners of the frame, I arrange screws for setting up the strips
which occupy those corners, and other screws can be arranged through the sides o
the frame to act upon the longer of the ribs, or strips.
The lipped clip pieces have two side wings which take a position between the
strips, or ribs and these are bound firmly in position for holding the plate, or plates
when the ribs, or strips are locked up. Some of the ribs, or strips may be wedge
shaped, or wedge pieces may be put in to be forced along between the strips to fix
them in position.
I also, in the event of a stereo, or other plate being larger than can be fixed in
position by the strips and clips, affix other lip pieces in slots in the edges of the frame
for fixing a large plate in position. These clipping pieces are adjustable for register.
Where the ribs or strips are necessarily kept apart by the wings of the clip pieces,
leads or strips may be placed in between them to give an equal bearing along their
full length.
The above improvements are applicable to curved beds for rotary machines, as
well as for flat bels for flat machines.

Improvements in or connected with Stereo Mounts or Beds with
Appliances for Fixing Stereo or other Plates thereon for Printing
Purposes.
I. ROBERT PURDY TICKLE, of 57 Achilles Road, West Hampstead, Middlesex, 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 certain improvements in mounts for stereo and electro
plates specially adapted for use with rotatory printing machines, and the object of

page_text: said invention is to render the placing of stereos much easier than by the usual
system, also to ensure a rapid accurate adjustment and positive locking of stereos,
whether of large or small size, on to mounts
The invention consists in constructing such as by casting, a metal frame with a
V shaped projecting inner rim or with a V shaped hollow inner rim, within which the
ends of diagonally arranged strips of metal, having their ends of V shape to correspond,
can be slid along or he pushed up towards one another, or opened out away from one
another in order that the mount may receive an electro or stereo plate of any size
within its own length and breadth, clip pieces being employed at the required
positions between the strips and provided with lips which take over the edges of the
plate to hold said plate in close contact with the mount.
I employ screws at two opposite corners of the mount for pushing the shorter of
the strips up towards the centre of the mount, or away from the respective corners,
other screws with nuts being arranged between certain of the longer strips and in
which the screws are adjustable for giving the nip at the proper places for locking
the clips as in a vice.
Should the stereo or electro plate be larger than the inner dimensions of the
mount, the strips with the top edge surface of the frame serve as a bed on which a
plate would find a level bearing, the edges of the plate being secured by other or
edge clips let into recesses in the outer edges of the frame, and in which recesses
some of the clips are fixed and some are adjustable by nuts when turned by a spanner.
1 employ printers ordinary leads in the spacings for obtaining an equal bearing
along the strips where the clips are arranged and such "leads
between other of the strips for register of the plate.
may also be used
To enable my invention to be more clearly understood, I annex a sheet of drawings
hereto.
Figure 1. a plan of a mount with V projections on inner edge of frame and with a
small stereo or electro plate locked on the strips by four clips.
Figure 2. a transverse section of the frame and strips suitable for rotary machine.
Figure 3. a sectional elevation of part of a frame having V shaped hollow and
V shaped projections or strips.
Figure 4. an elevation of a separate clip on a strip to show the side wings, which
when jambel between two strips is locked in place.
Figure 5 is a plan view of a mount without edge clips.
Similar letters refer to similar parts through the several views.
A is the frame of rectangular shape with an inner rib B of V shape. This frame
has in its outer edges, a series of notches for lipped clipping plates C, C, which are
fixed in position by screws or pins not shown, and with another series of notches of
greater depth for the reception of movable lipped clipping plates D, D, which are held
in position by the side walls of the notches and carried by screws E, E, on which, nuts
can be turned by a spanner for the adjustment of the plates D, D. These screws E, E,
are rivetted to the cover plates G, G, which are screwed to the outer edges of the
frame A in a similar manner to the clipping plates C, C.
H, H, are diagonal strips with their ends of V shape to correspond with the ribs B
of the frame A on which they can be slid close to one another or farther apart when
desired.
I, I, are loose fitting clips, the lips of which are shaped like those of the clips C, D,
for bearing upon the chamfered edge of the stereo J when placed upon the diagonal
strips H. H. These clips I, I, have bent down wings K, K, which engage between
the diagonal strips I, II, between which said wings are pinched when the "locking
up" is effected to bind the clips I, I, and stereo plate J firmly on the strips H, H,
ready for the printing operation.
Two of the diagonal strips, say, L, L, have longitudinal grooves in them, one being
plain for the stems of screws M, M, to slide in, and the other mitred for the heads of
the screws M, M, to slide in, so that said screws can be set at any part of the diagonal
strips L, L, these strips being set farther apart by turning the nuts N, N, in the
proper direction for locking the strips H, H, closely against one another.

page_text: The longer of the diagonal strips H, H, are very effectively closed up by the
screws M, M, and the shorter ones have separate screws P, P, inserted through the
opposite corners of the frame A to force them up. This however is only necessary
when the stereo plate is of a size for the locking up to be effected by those strips
alone.
In lieu of the corner screws P, F, I may use wedges passing through the sides of
the frame near the corners to effect the same purpose.
Stereo plates of irregular sizes can be secured on the mount of my invention, it
only requiring some printers leads being placed between the strips to make for the
difference of the sizes between a regular or stock sizes of stereos and those of
irregular sizes and such "leads" which should correspond in thickness to the
wings K, K, can be used between the diagonal strips H, H, for giving an equal
bearing along the strips, between which they also act as cushions when the screwing
up for locking purposes is effected.
I am aware that diagonal strips have hitherto been employed in a frame on which
storeo plates have been secured, and that means have been adopted for fixing the
diagonal strips in position in such frames, therefore I do not claim broadly the use of
diagonal strips in a frame for the purpose but
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In a stereo mount frame A, the ribs B, B, diagonal strips H, H, with ends of
corresponding shape to ribs B, B, and arranged to move parallely in said frame A
locking screws M and nuts N adjustable along and between said strips, substantially
as described.
2. In a stereo mount frame A having diagonal strips H, H, the loose clips I, I,
with side wings K, K, substantially as described.
3. In a stereo mount frame A, the slotted diagonal strips L, L, locking up
screws M, M, and nuts N, N, substantially as described.
4. In a stereo mount frame A having diagonal strips H, H, sliding on ribs B, the
fixed clips C, C, and adjustable clips D, D, screws E, E, and nuts substantially as
described.
5. In a stereo mount frame A having diagonal strips H, H, the corner screws P, P,
substantially as described.
