IMPROVEMENTS IN MACHINES FOR BRANDING OR PRINTING IN WOOD OR SIMILAR MATERIAL
Year: 1885

page_text: COMPLETE SPECIFICATION.
I, JOHN COLLIS, Central Works 12 & 14 Ironmonger Row in the Parish of
St Lukes in the county of Middlesex, Engineer, do hereby declare the nature of
my invention for IMPROVEMENTS IN MACHINES FOR BRANDING OR PRINTING IN
WOOD OR SIMILAR MATERIAL, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement:-
My Invention consists of a machine for branding wood such as parts of packing
cases or like articles in the manner as hereinafter described and illustrated in the
accompanying drawing.
This machine consists of a frame which I will call the bed as shown
in the accompanying drawing to which two stands "6" and "b"
bolted.

In these stands and between the stands and the bed work two slides "
and "c" in a reciprocating motion at both sides of the machine. The slides are
connected by two bars an upper one
d" and a lower one "d." The lower bar is
connected to the driving shaft "e" by eccentrics "f" and "f1" by which the
machine is operated.
Below the upper bar "d" Fig: 1 and between the slides is fitted an adjustable
plate "g" which is connected to the bar "d" by two adjusting screws "h," and "h¹"
and below this is fitted a box "j" which I will call the pressure plate.
This pressure plate is connected to the adjustable plate "g" by four studs as
sbown "k" Figures 1 and 2 and springs are placed in between the pressure plate
and the adjustable plate as shown "" and "" Fig: 1. On the bed is placed a
heating box "m" which is more fully illustrated in Fig: 4 Section Fig: 4 A and
Section Fig: 4 B.
This box consists of a frame "m" Fig: 4 which is recessed at the inner side
round its rim in which recess the brand plate "n" is fitted.
This frame is divided into three or more chambers by ribs "o." These ribs at
the same time carry the brand plate and prevent it from breaking.
In these chambers are fitted tubes "p" Fig: 4 which are provided with holes
round the upper side. These tubes I will call heat accumulators.
Into these accumulators gas is inserted by a blast at the one end and ignited
therein, the other end is closed and by these the brand plate is heated.

Section Fig 4 A
:
The frame is provided with air holes round its sides and in the ribs.
Now when the material which is to be branded is placed in the machine on the
brand plate the slides "c" and "c1" descend, and the pressure plate is forced on to
the material and the springs are compressed, at the same time the four studs slide
up in the adjustable plate, by this an automatic adjustment of pressure is effected
in case of variety in thickness of the material at the same time applying the
pressure for a sufficient time for the branding to be effected before the slides ascend
sufficiently to release the material.
The pressure is adjusted by the two adjusting screws "h" and "h" Fig: 1 to
which the adjustable plate in combination with the pressure plate is connected.
Figure 1 is a side view of which the one side is sectioned.
2 is an end view of Fig: 1.

Figure 4 A is a section of Figure 4 with the brand plate on.
4 B is an end section of Figure 4 with the brand plate off.
The small letters relate to the same part in the various figures.
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 application of springs for the purpose and in the manner as heretofore
substantially described and illustrated in Figures 1 and 2 in the accompanying
drawing.
2nd The application of a heating box in the manner as heretofore substantially
described and illustrated in the accompanying drawing.
