COMPLETE SPECIFICATION.
Improvements in Means or Apparatus whereby Special Matter may
be Rapidly Inserted or Substituted in Stereotype Plates for
Printing Newspapers or other Publications.
We, JOHN CUNNINGHAM PETCH, Printer's Engineer, and THOMAS MUSSELL,
Watchmaker, both of Middlesborough on Tees, in the County of York, 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 means or Apparatus, whereby types or logotypes may be
rapidly inserted and fixed in the stereotype plates, from the face of the same, whilst
secured on the cylinders of any web rotary or other machine for printing newspapers
or other publications, so that the general contents of a newspaper or other pub-
lication may be prepared on the usual Stereotype plate, and other matter may be
added such as important items of news arriving too late to be made up at the time
of casting the said Stereotype plate, the types or logotypes printing such additional
matter being so inserted, and fixed, that they can be removed, and replaced, by other
types or logotypes, should it be desired to substitute some other matter for the said
additional matter, without disturbing the stereotype plate of the general contents
of the newspaper or other publication.
This Invention consists a rectangular flat frame, chase or box, having four sides
& a bottom. One end is inclined, and has a spring on it. The opposite end has in
its body a spiral spring acting so as to press out two catches. The bottom of the
frame, chase or box is curved to fit the cylinder.-In the Stereotype plate, is pre-
pared an opening, corresponding to the shape of the frame, chase or box. When it is
desired to insert the frame, chase, or box, the inclined end is slipped in: then, by
pressure, the other end goes into its place: the catches spring out into recesses pre-
pared in the stereotype plate, and the frame, chase or box is securely held. To
withdraw the frame, chase or box, a pair of spring pliers or pincers are inserted, so
as to press back the catches, into the body of the frame, chase or box, when it can
be removed. The solid end logotype is held horizontally by the types or logotypes,
& vertically by two lips, on the frame, chase or box, bearing upon it.

page_text: We now proceed to explain the drawings, which are shewn on Sheet No. 1 &
final. Fig. 1. is a side clevation of the frame, chase or box. Fig. 2. an end eleva-
tion of inclined end.--Fig. 3. an elevation of the opposite end.-Fig. 4, a plan,
Fig. 5, a cross section at A, B, Fig. 6. cross-section at C, D, Fig. 7. longitudinal
section at E. F, & Fig. 8, a cross-section at G. H.
X is the frame, chase or box, Y is the stereotype plate, A, A, are the catches,
and a, a, are small projections upon them to regulate the action of the catches. B is
a spiral spring acting upon the catches A, A, pressing them outwards, the catches
being sloped at the ends, are forced inwards, when the frame, chase or box is being
pressed into the opening in the stereotype plate. C. C are the set screws holding
the types or logotypes in the frame, chase or box. Z shews the spring pliers or
pincers, being inserted. D is the spring, secured on the inclined end of the frame,
chase or box. G the solid logotype, at the ends of the types, or logotypes.
Having now particularly described and ascertained the nature of our Invention,
and in what manner the same is to be performed we declare, that what we claim is:
First. The addition of a bottom to the frame, chase or box, whereby the proper
position of the type or logotype carried in the cases is at once secured.
Second. The form of the inclined end with its spring, which causes the frame,
chase or box, to be held vertically & horizontally at the same time.
Third. The solid logotype at the end of the frame, chase or box, and the manner
of securing it, by means of the lips H on the frame, chase or box.
While claiming and preferring the improvements herein described, we also claim
all the improvements contained in the Patent of Petch and Marshall No. 13376,
dated October 9th 1884.
Dated this 15th day of January 1889.
