page_text: Improvements relating to Box Covering Machines.
I, THOMAS BISHOP, of 44 Deritend, in the City of Birmingham, Manufacturer,
do hereby declare the nature of this invention to be as follows:-
This invention consists of improvements relating to box covering machines, my
object being to produce an expansible or segmental supporting block having simple
and effective means for ready adjustment to the required size of box to be operated
upon, and to so construct and arrange such adjustable means or appliances that
the block segments can be rigidly secured in any position to which they may be
set within the range or limit of adjustment.
In the application of my invention I employ a base piece fitting within the
interior of the segments and having a central aperture for the reception of the
block spindle of the machine to which the block is to be attached. The base
piece fixes the minimum dimensions of the block, the interior surfaces of the
segments abutting against the base piece when in their innermost position.
Upon the base piece I mount a slotted bridge piece or carrier which supports a
pair of double arms each provided with longitudinal slots. Each pair of double
arms are secured to the slotted bridge piece or carrier preferably by a thumb
nut and screw stud, but on releasing the nuts the arms can be extended within
the limits of the slot to suit the particular box to be operated upon. The adjust-
ment in the one direction is effected by the movement of the slotted arms
relatively to each other, and in the other direction by moving either or both pairs
of double arms along the slotted bridge.
One end of each arm is attached to one of the segments forming the box and
thus as the arms are moved the segments partake of their movement, but when
the arms are fixed by the thumb nuts, the segments are rigidly secured in the
position to which they have been adjusted.
Instead of employing arms to slide over or upon each other as hereinbefore
described, I sometimes employ solid or tubular rods to slide within tubes or
sockets fitted with clamping screws or other securing devices, and I make such
other modifications in the application of my invention as may be necessary to its
best adaption for any required service.

page_text: I, THOMAS BISHOP, of 44 Deritend, in the City of Birmingham, Manufacturer,
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 consists of improvements relating to box covering machines, my
object being to produce an expansible or segmental supporting blocks having simple
and effective means for ready adjustment to the required size of box to be operated
upon, and to so construct and arrange such adjustable means or appliances that
the block segments can be rigidly secured in any position to which they may be
set within the range or limit of adjustment.
In the application of my invention I employ a base piece fitting within the
interior of the segments and having a central aperture for the reception of the
block spindle of the machine to which the block is to be attached. The base
piece fixes the minimum dimensions of the block, the interior surface of the
segments abutting against the base piece when in their innermost position.
Upon the base I mount a slotted bridge piece or carrier which supports a
pair of double arms each provided with longitudinal slots. Each pair of double
arms are secured to the slotted bridge piece or carrier preferably by a thumb
nut and screw stud, but on releasing the nuts the arms can be extended within
the limits of the slot to suit the particular box to be operated upon. The adjust-
ment in the one direction is effected by the movement of the slotted arms
relatively to each other, and in the other direction by moving either or both pairs
of double arms along the slotted bridge.
One end of each arm is attached to one of the segments forming the box and
thus as the arms are moved the segments partake of their movement, but when
the arms are fixed by the thumb nuts, the segments are rigidly secured in the
position to which they have been adjusted.
Instead of employing arms to slide over or upon each other as hereinbefore
described, I sometimes employ solid or tubular rods to slide within tubes or
sockets fitted with clamping screws or other securing devices, and I make such
other modifications in the application of my invention as may be necessary to its
best adaption for any required service.
In order that my invention and the method of carrying the same into effect
may be the more readily understood I append hereunto a sheet of explanatory
drawings to be hereinafter referred to.
Figure 1 is a sectional side elevation, Figure 2 a sectional end elevation, and
Figure a plan of a supporting block, constructed in accordance with my inven-
tion; the drawings illustrating the block at the minimum dimensions or compass
for which it is constructed.
Figure 4 is a plan illustrating a method of stiffening or staying the box by
extensions on the sliding arms, and Figure 5 a sectional end elevation of one pair
of such arms through the line a b at Figure 4.
Figure 6 is a sectional side elevation and Figure 7 a sectional end elevation
representing the outer or angular segments of the box extended to the maximum
range of adjustment.
Figure 8 is an elevation to a larger scale representing the construction of the
telescopic joints of the segments and also the arrangement of the stops.
The same reference letters in the different views indicate the same parts.
I employ a base or bridge piece or carrier such as A having its upper part

page_text: within the interior of the block segments, and provided with a central aperture A¹
through. the lower part for the reception of the block spindle of the machine to
which the block is to be attached. In the upper part of the base piece A, I form
a slot or slots A³, and such slotted part supports a pair of double arms B BI
and CC each provided with longitudinal slots. Each pair of double arms is
secured to the slotted base or bridge piece or carrier A preferably by a thumb
nut and bolt as illustrated, but on releasing the nuts the arms can be extended
within the limits of the slot to suit the particular box to be operated upon. The
adjustment in the one direction is effected by the movement of the slotted arms
relatively to each other, and in the other direction by moving either or both pairs
of double arms along the slotted bridge. In Figure 1 each pair of arms is at the
inner position upon the slotted bridge A whereas in Figure 6 they are shown at
their outer-most positions. In the same manner at Figure 2 the arms B and C
are shown at their inner positions, whereas at Figure 7 they are represented at
their outer-most positions.
One end of each of the arms B B₁, C C¹ is permanently attached by soldering
or otherwise to one of the outer or angular metal or other plates or segments
forming the box block, and thus as the arms are moved such segments partake of
their movement, but when the arms are fixed by the thumb nuts, the segments
are rigidly secured in the position to which they have been adjusted. The sliding
or telescopic segments are prevented from complete detachment when, in the
outermost positions, illustrated at Figures 6 and 7, by means of stop pegs D upon
or adjacent to the ends of the segments, such stop pegs being formed from strips
or lengths of wire soldered or otherwise attached to their respective segments.
In constructing a box block of large dimensions in accordance with my inven-
tion I provide lateral extensions as E E' (Figure 4) upon the sliding arms for the
purpose of stiffening or staying the adjustable segments.
The telescopic joints of the segments are formed at the upper and lower ends of
the plates by turning over such edges of the plates to a tubular form, such as
shown more clearly in the detail view, Figure 8, the tube on one plate being
arranged to slide within the tube of the adjacent plate. The tubes formed with
the central plates or segments F F¹ and G G¹ on each side are large or outer
tubes, whilst the tubes formed with the angular plates or segments, Hand
JJ are smaller or inner tubes, arranged to telescope or slide within the outer
tubes formed with the central plates. It will thus be understood that the complete
box block is made up of four central plates or segments and four angular plates
or segments, each of the sliding arms B B and C C¹ being rigidly attached to
one of such angular segments which are themselves arranged to slide or telescope
upon the said segments.
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. An adjustable supporting block for a box covering machine constructed and
arranged substantially as and for the purposes described.
2. An adjustable segmental block for a box covering machine having exten-
sible supporting arms within its interior and means for securing the same in
varying positions upon the bridge piece or carrier, such bridge piece or carrier
forming the connection with the spindle of the machine, substantially as described
and as illustrated.
3. The combination with a segmental block for a box covering machine of
slotted arms as B B and C C¹ so mounted in pairs upon a slotted bridge piece or
carrier A that the two pairs can be caused to recede from or approach each other
in one straight line direction, and the two arms of each pair to recede from or
approach each other in a straight line direction at right angles to the movement
of the arms in pairs, substantially as described and as illustrated.
4. The combination with a segmental block for a box covering, machine of

page_text: adjustable arms having lateral extensions E E¹, substantially as and for the
purpose described and as illustrated.
5. The combination in an adjustable block for a box covering machine of sliding
or telescopic segments having stop pegs D, substantially as and for the purpose
described and as illustrated.
