DESCRIPTION OF DRAWINGS.
Fig. 1, sheet 1, of the accompanying drawings is an end elevation of my double
new or improved combined self-acting machine for roughing and boring bobbins or
spools and other analogous articles-Fig. 2, sheet 2, is a plan of same-Fig. 3,
sheets 3 and 4, is a longitudinal side elevation-Fig. 4 is a part sectional elevation of
boring spindle and its connections, and Fig. 5 is a part plan of cutters and their
carrying frame for sawing underneath the block when roughing and boring coppice
or uneven round wood is being performed.
In all the figures the same letters and numerals are used to indicate corresponding
parts.
A is the framework of the machine; B the driving shaft with the wheel C geared
into the wheel D on the shaft E, the latter being provided with the fast and loose
pulleys F and G respectively; by which the machine can be driven from any suitable
or convenient source by a strap. The shafts H are fitted with the spur wheels J both
of which gear into the spur wheel K on the shaft B. L is the boring spindle mounted
in the bearings M on the headstock N. The boring spindle L is provided with the

page_text: tubular saw O and the boring bit P, shown in section in Fig. 4. On the front of the
machine and in the centre line of each boring spindle are disposed the revolving
tables R for receiving and placing the blocks of wood in position ready for operation.
The revolving tables R are mounted on the hollow spindle S; on the lower end of the
latter are secured the sliding boxes T. The hollow spindles S pass through the revolving
tables U which with the spindles S are supported in the bearings V secured to the
framework A. The hollow spindles S are mounted on the spindles W carrying the
grips X on their upper end; the lower ends of the spindles W being held in position
by the bearings Y on the framework A.
This machine is specially designed for roughing and boring bobbin or spool blocks
at one operation from coppice or rough uneven wood as shown in Fig. 6, which is also
equally applicable for roughing and boring bobbin or spool blocks from square wood
as shown in Figs. 8 and 9, and operates as follows:-The attendant places the wood
blocks 10 on the tables R, and then the latter are revolved step by step or intermittently
until the wood blocks 10 are presented in front of or in line with the boring spindles L.
The revolving tables R are fitted with the adjustable supports 74, which can be set
horizontally according to the size of the blocks of wood to be operated upon by means
of the screws 75 and slotted holes 76. To prevent the blocks falling from the revolving
tables R when nearing the line of operation and from the line of operation to the line
of delivery the sheet-iron guards 77 are provided, which are attached to the
framework A of the machine in any convenient manner. The step by step or
intermittent motion of the tables R is caused by the pins 11 on the discs 12 striking
the prongs 13 on the sliding boxes T, which revolve the same one-fourth of a revolution
at a time. The position of the grips X-when roughing and boring is to be
performed is ensured by the squared sides 14 of the sliding boxes T resting against
the face of the discs 12 as in Fig. 3. To allow the sliding boxes T with the square
sides 14 to revolve when operated upon by the pins 11 the openings 15 and recesses 16
are provided in the discs 12. The sliding boxes T are secured on the spindles W,
and the spindles W carrying the grips X are revolved or turned by float-keys and slots
in the said spindles. The spindles W carrying the grips X can be adjusted vertically
by the screws 78 and nuts 79, the same being supported by the fixings 80 on the
framing A of the machine.
Immediately a rough block of coppice wood is presented by the grips X before the
boring spindle L the roller 16 on the lever 17 is released from the cam 18 on the
shaft H as shown in Fig. 1. The lever 17 is pivoted to the framework A of
the machine by the pin 19. As the roller 16 is being released from the cam 18
it is forced downwards by the weight 20 on the spindle 21. The spindle 21 is held in
position by the fixings Z secured to the framework A; and the spindle 21 is provided
with the arm 81 which slides on the facing 82 to prevent the spindle swivelling. The
spindle 21 is provided with the crossbar 22, one end of which is attached to the
lever 17 by the link 23; the opposite end being attached to the double lever 24 by
the link 25. The double lever 24 is pivoted to the fixing 26 by the piu 27; the
opposite end or ends being provided with the pin or pins 28 which operate in the
groove or slot 29 in the sliding boxes T, and lifts the revolving tables R as shown on
the right hand side of the machine in Fig. 1. By the descent of the spindle 21 the
arm 30 attached thereto places the presser 31 on the upper side of the rough block of
coppice wood 10. The presser 31 is adjustable vertically by means of the slot 83 and
bolt 84. While this operation is being performed and before the full weight of the
presser 31 is on the rough block of coppice wood 10 the sliding presser 32 mounted
inside the hollow boring spindle L advances by the sliding action of the boring
spindle Luntil it comes into contact with the block of wood 10 and holds it fast on
the saw toothed end of the grip X. The presser 32 is attached by a pin to the arm 33
on the boring spindle L, and the lower end of the arm 33 is attached to the spindle 34
mounted in the headstock N. The spindle 34 is fitted with the arm 35 to which is
attached the chain 36 which passes over the pulley 37 on the frame A. To the end of
the chain 36 is attached the weight 38 to hold the presser 32 firmly against the block
of wood 10 while the tubular saw O advances with the boring bit P and roughs and

page_text: bores the same at one operation. Immediately the presser 32 is in contact with the
block of wood 10 against the grip X the advance of the arm 33 and the spindle 34 are
arrested, during which the spindle Ladvances with the tubular saw O and boring bit P.
For a certain distance the hollow presser spindle 32x is provided with a slot to admit
of the inner end of the boring bit P, and the latter is secured by the set screws Ox in
the socket of the boring spindle L as in Fig. 4 A. The slot in the hollow spindle 32×
allows of the traverse of the boring bit P with the boring spindle L after the traverse
of the presser 32 has been arrested by the wood block 10 to be operated upon. The
spindle L is provided with the slot 41 to admit of its travel after the presser 32 has
come to a stand still. The spindles L are provided with the pulleys 39 and driven by
the strap 40 from any convenient source." The pulley from which the pulley 39 is
driven by the strap 40 is sufficiently wide to allow of the travel of the spindles L.
The spindles L carrying the tubular saws O and boring bits P are moved to and fro in
the bearings M by the grooved cam 42 on the driving shaft B: the grooved cam 42
operates the arm 43 attached to the slide 44, the latter being connected to the
crossbar 45 by the rod 46. The crossbar 45 is provided with the adjustable screwed
ends 47 which operate in the box L' on the end of each boring spindle L as shown
in Figs. 2 and 3.1 When the tubular saw O and the boring bit P have completed the
double operation they are moved backwards clear of the wood block, and as the
slide 44 carrying the pivoted lever 44* comes in contact with the stop 34* on
the framing A the bar 45* operates against the arms 46* on the spindles 34 and
pushes the pressers 32 backwards past the end of the boring bits P to allow of the
latter being greased automatically or by hand as desired prior to each operation.
When this operation is completed the cam 18 on the shaft H operates on the roller 16
on the lever 17 and depresses the sliding box T, spindle S, and table R as shown on
the left-hand side of Fig 1, which also raises the presser 31 from the top of the
roughed and bored block, after which the grips X are revolved another step or
one-fourth of a revolution as before described which places the roughed and bored
block in position to be removed and the next unworked block in position before the
presser 32, tubular saw O, and the boring bit P when the operation is repeated
continuously as described.
To enable the tubular saw O to perform its work when operating on coppice or
uneven round wood it is absolutely necessary that the saw-dust should be got away as
produced which is effected by means of the cutter or cutters 48 on the shaft 49
mounted in the bearings 50 on the oscillating frame 51. The oscillating frame 51 is
mounted on the slide 52 by the pin 53. The oscillating frame 51 is attached
to the crossbar 52*, each end of which is provided with the rollers 53, which
operate in the stationary slide bars 54. The slide 52 carrying the oscillating frame
and appendages is traversed in both directions by the grooved cam 55 on the shaft B
operating on the arm 56 attached to the underside of the slide 52. The cutter or
cutters 48 are revolved by the pulley 57 on the shaft 49; the same being driven by
the band 58 or its equivalent from any suitable source. The cutter or cutters 48 are
placed slightly in advance of the tubular saw O and cuts or saws the outside or waste
portion of the coppice or uneven wood block 10 sufficiently to allow the same to
break by the action of the tubular saw 0, by which the saw-dust drops out on the
underside as it is made. As the cutter or cutters 48 advance towards the block of
wood 10 to be operated upon the former rises to the position shown in Fig. 4 by
means of the rollers 53 moving in the inclined stationary slide bars 54.
When the roughed and bored blocks are moved by the revolving tables R to a
position at right angles or thereabouts to the centre line of the spindle L it is of vital
importance that the roughed and bored block should be separated from the outside or
refuse part of the same to make the machine thoroughly self-acting. This is performed
by mounting on the arm 30 on the spindle 21 the sliding rod 59 mounted in the
bearings 60. On the rod 59 are mounted the forks 61 and 62, the latter being for
the purpose of holding the outside or waste portion of the block while the lever 62×
strikes and knocks out the roughed and bored block as in Fig. 7. The lever 62* is
attached to the arm 30 by the pillar 63 and the pin or centre 64. On the other end

page_text: of the pin or centre 64 is fixed the lever 65, the outer end of which passes through
the slotted arm 90 on the spindle 91. The spindle 91 is held in position vertically by
the bracket 92 on the fixing Z and the fixing 93 on the framing A. Immediately the
bottom end of the lever 62× drops into the grips X as shown on right hand side of
Fig. 1 the pin 95 on the disc 94 on shaft H strikes the end of the pivoted lever 96
and lifts the spindle 91 causing the lever 62* to strike the roughed and bored block,
by which the latter is thrown a distance from the machine or into a shoot or other
receptacle. The spindle 91 is attached to the rod 21 by the arms 97 to ensure both
lifting together for the purpose of lifting the lever 62× clear of the grips X while the
latter revolves as shown on left-hand side of Fig. 1. The spindle 91 is provided with
the weight 98 to ensure its dropping when the lever 96 is released from the pin 95
on the disc 94. When the lever 96 is released from the action of the pin 95 it drops
with the spindle 91 onto the stationary pin 99, which is for the purpose of determining
the position of the lever 96 ready for the next stroke of the pin 95. When the
lover 62 is raised clear of the grips X as shown on left-hand side of Fig. 1 the
the table R and grips X are at liberty to revolve when requisite. When the roughed
and bored block has been removed the fork 61 slides in the direction indicated by the
arrow by means of the arm 68 and the double lever 69, the latter being pivoted to the
frame A by the pin 70. The double levers 69 are fitted with the pins 71 which fit
in the slots 72 in the slide 44, the whole being operated by the sliding action of the
latter. When the waste portions of the blocks are forced or pushed off the tables R
by the fork 61 they fall onto the floor, and in case they drop onto the revolving tables U
they are pushed or cleared therefrom by the stationary scrapers 73. The revolving
tables U are employed to keep the front or feeding position of the machine clear of
the waste portions of the blocks after they are pushed off the revolving tables R.
An important feature of this invention is that in the case of operating on irregular
round coppice or uneven sizes of rough wood blocks the tables R and the pressers 31
act in unison by which self-centring of the rough block to be operated upon is effected
between the grips X and presser 32, the tubular saw and boring bit P.
When the machine is intended to operate on square blocks as in Figs. 8 and 9 the
self-centring apparatus can be disconnected by simply removing the pins 85, when
the tables with the adjustable supports can be set to any stationary height; the
presser 31 operating in connection with the upper side of the blocks as previously
described. In this case also the cutters 48 and apparatus for operating the same are
disconnected or dispensed with as they are unnecessary for square and even wood.
Fig. 10 is a part front elevation of my improved apparatus for solf-centring
irregular round coppice or uneven sizes of rough wood blocks in vertical combined
self-acting machines for roughing and boring bobbins or spools-Fig. 11 is a part side
elevation of same, and Fig. 12 is a part plan through line E' F' in Fig. 10.
The tables R are fitted with the hollow grips X to receive the wood blocks 10 as
shown on left hand side of Fig. 10. When the wood block 10 is placed under the
boring spindle L the operation is as previously described. As soon as the wood
block 10 is presented under the boring spindle L and before the presser 32 operates
on the upper side the lever 100 is released from one of the pins 101 on the revolving
disc 102 on the shaft H, when the weight 103 operates the levers 104 and 105 on the
shafts or centres 106, both sides being coupled by the levers 107 and rod 108. The
levers 105 operate the horizontal sliding pressers 31 against the wood block as in
Figs. 10 and 12.
The pressers 31 are mounted in the slides 109 on the framing A of the machine.
Immediately the presser 32 on the boring spindle L is in contact with the upper side
of the block 10 the next pin 101 on the disc 102 operates on and lifts the lever 100
by which the pressers 31 are slid backwards to allow the next block to pass when the
table R revolves. The discs 102 are each provided with the pins 101 to operate the
self-centring apparatus four times in each revolution of the table R. After the block 10
has been roughed and bored and the boring spindle and its attachments have been
raised therefrom the table R revolves one fourth of a revolution by the means described
and shown in Figs. 1 and 3, or by other equivalent means, and places the roughed and

page_text: bored block over the vertical punch 110; the latter being attached to the arm 111
and spindle 112. The spindle 112 is square and is mounted in the boss 113 on the
framing A by which its correct position is ensured. When the roughed and bored
block 10 is in position over the punch 110 the latter is lifted vertically to knock the
roughed and bored block out of the outside or waste portion by the pins 101 on the
disc 102 striking the pivoted lever 115, and so on, the operation being repeated
every time a block is placed over the punch 110.
After the roughed and bored block has been removed the outside or waste portion
is left on the table R and over the hollow grips X, and as the table R revolves the
outside or waste portion is lifted from the table R and hollow grips X by the stationary
incline 116 attached to the framework A.
In case it is desired to rough and bore more than two bobbins or spools at once, the
same is performed by providing the machine with the requisite number of boring
spindles and other parts according to the number of hobbins or spools required at
one operation.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In a self-acting machine for roughing and boring two or more bobbins or spools
at one operation the use of the tables R for the purpose set forth.
2. In a self-acting machine for roughing and boring two or more bobbins or spools
at one operation the use of the revolving grips X for the purpose specified.
3. In a self-acting machine for roughing and boring two or more bobbins or spools
at one operation the use of the tables U for the purpose specified.
4. In a self-acting machine for roughing and boring bobbins or spools at one
operation the use of apparatus for self-centring rough uneven round blocks of wood
between the grippers X and the presser 32.
5. In a self-acting machine for roughing and boring bobbins or spools at one
operation, the combination of the boring spindle L, tubular saw O, boring bit P,
and presser 32, applied and operating substantially as described and shown on the
drawings.
6. In a self-acting or other machine for roughing and boring bobbins or spools the
use of the cutter or cutters 48 for the purpose specified.
7. In a self-acting machine for roughing and boring bobbins or spools the use of
apparatus for separating and removing the roughed and bored blocks from the external
or waste portion thereof substantially as described and shown on the drawings or any
nere modification' thereof.
8. The general construction, arrangement, and combination of parts forming my
new or improved combined self-acting or other machine for roughing and boring two
or more bobbins or spools at once, substantially as described and as shown on the
drawings.
