page_text: I, THOMAS HOULDING BROMLY Engineer Osborne Street Colchester in the County
of Essex. 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 :-
The Iron Table T which is mounted on suitable Legs or Standards to carry the Fly
wheel &c. has a planed opening along the Front U thus forming a Lathe bed
extending the length & forming a part of the Saw Table, the said opening acting as a
Guide into which are fitted the Headstocks, Poppets, Slide Rests, Fences or Guides
(for wood) & other appliances.
The frame work Y hereinafter called the Drilling Machine Frame which is
detachable being secured to Table T by a single hold down bolt & held in position by
suitable Lugs fitted into opening U may be used in position shown in Drawings or
may be turned entirely round so as to overhang the end of Saw Table when drilling
Bulky articles the Pulleys being so placed that it will run either way, or it may be
removed so as to leave the Top of Saw Table entirely clear when desired.
An opening is cast near the base of Frame Y with suitable bosses carrying the
speed bore of Lathe. B is a Vertical spindle, working through Frame Y to carry
drills, Mortice Chissells, Cutters & other appliances, which spindle is caused to
Revolve by means of Pulley P the driveing band, passing from the Fly Wheel
beneath the Saw Bench over Guide Pulleys attached to Frame Y & so Round
Pulley P.
Lever, O, which imparts the up & down motion to spindle when Drilling,
Moiticeing &c. consists of a Forked Lever, working on Pivot or Studd on drilling
Machine Frame at M & haveing a Circular enlargement or Boss at N the Top side of
which works against Pulley P & the under side rests on adjustable Clip A. Clip A
& Pulley P being fastened to spindle B by set screws or other suitable means &
Lever, O, being a fork which passes on each side of drill spindle thus spaning it, it is
evident that the said spindle will be free to revolve while being Raised or Lowered by
said Lever. When Drilling Guide Spindle V must be removed, but when Morticeing
Guide Spindle V must be dropped into position shown & passing through holes

page_text: in Pulley, P prevent it from revolving causing spindle B to move up & down
without turning when actuated by Lever, O. Chisels for Morticing are fixed in
Lower end of Spindle, B & the holes for Guide Spindle V being placed exactly
opposite to each other in Pully P by withdrawing the Guide; Spindle & turning the
Pulley half way Round so that it passes down through the opposite hole in Pulley, P
the Chissels will be reversed so as to finish off both ends of Mortice.
Sis a spring resting on end of Lever O for raising drill spindle to its highest point,
this may also be attained by extending Lever beyond the frame & attaching a weight,
W is an ordinary Compound Slide Rest which when fitted with its Tool holder is used
in the customary manner for turning purposes. This Rest is plained on the under
side to fit the Lathe Bed, not only in the ordinary manner but at right angles also so
that the direction of the slides may be reversed, which is done when used for
morticing &c. The tool holder being removed the Box Frame C with Cramping.
screw for carrying the wood &c. is attached, on the underside of Carriage Cisa
Rack engageing with Pinion D' by which it is moved backwards & forwards in
forming the mortice. The screw of the Top Slide must of course be removed
when useing the rack but the screw may be used to move the slide instead of the
Rack if desirable when the Rack may be dispensed with.
An ordinary Lathe Poppet is used to carry the back Centre in turning & an
extension Bed K is added if required.
When used as a Punching machine for Blind Laths &c. &c. the
end of Spindle B & a suitable Bolster or die attached to the Table.
left in place as in Morticing.
Punch is fixed in
Spindle V being
When used for moulding the Cutters are fixed in lower end of spindle B, which
is lowered to position required & there held by an extra collar & set screw slipped
over spindle B & fastened to it, so as to run on the outside of the frame Y through
which spindle B works, remove Guide Spindle V & the spindle carrying the cutter
will then be free to Revolve & the work to be operated on can be fed to it in
the same way as an ordinary Moulding Machine by resting it on Top of Saw
Table against suitable templates or Guides. The Cutters acting from the Top side
of the work instead of beneath.
In cutting Key ways, Slots &c. Clamp the article to be operated on in Frame C
at Top of Slide Rest W & by means of the slides it may be moved in either
direction the cutter runing in Vertical Spindle the same as in Moulding or Drilling.
When Milling with Cutters runing in Lathe Head Slide Rest W is turned on
its side & fastened to a suitable angle Bracket so that wood Carriage (faces the
Headstock the side of said carriage then forms a platform on which to Clamp the
article to be milled & is traversed either vertically or horizontally by the cross
slides & Screws.
The Drilling spindle B is placed at right angles with the bed of machine &
directly over the line of Lathe Centres so that by aid of an index on Headstock
any number of holes may be drilled in Circular Articles mathematically correct. &
by raiseing or lowering the Poppet Centre at any angle especially applicable to
drilling Hubbs of Bicycles, naves of wheels & similar articles.
By a novel arrangement the Circular saw may be raised or lowered for Groveing
Rabbiting etc. or passed completely below the table, so as to drive the Jig saw
(hereinafter described) without the necessity of removeing the Circular Saw from
its spindle & without altering the length of or in any way interfereing with the
driveing Belt.
F is a swinging Frame suspended from the under side of saw
Table by Trunions L at each side, working in Brackets or Bearings attached to &
dependant from the Saw Table. The right hand Bracket in Centre of Table being
in form of a J to allow the Frame F to swing sufficiently round to bring the
Counter shaft directly over the Trunions when the saw raised to its highest point.
In a line with & runing through the Trunions are Adjustable Centres or a Revolving
shaft whichever is found most suitable carrying a heavy Balance wheel in Centre,
with a small Pinion on one side & a Pulley on the other & driven at a high
Velocity from the main Driveing Wheel Direct. One side of Frame F is extended

page_text: & forms a bearing through which runs a Counter Shaft, the one end of which
carries a Circular saw & the other a wheel gearing, into the Pinion on shaft
Running. between Trunions already described. The gearing of a small Pinion on
the Trunion shaft into one larger on the Counter Shaft gives increased power to
the Saw while the High Velocity at which the Balance Wheel is driven ensures a
good cutting speed to the saw & greatly assists it. E is a quadrant with handle,
attached to one of the Trunions & comeing on the outside of Saw Bench by which
means the Frame F'is caused to swivel on its Trunions and thereby the saw is lowered
or raised to the desired position & so held by tightening Fly nut J. The screwed
disc H which secures the saw on Counter shaft instead of an ordinary nut, is drilled
on the face out of Centre & a stud affixed to form a Crank Pin, which is connected by
à link to a vertical spindle carried in a suitable Frame suspended from the Saw Table
which spindle is thereby caused to move up & down, a vertical Jig Saw is attached to
this spindle & passing up through the saw Table is attached to a swinging arm pivoted
at back of machine. A similar swinging arm is attached to the Vertical spindle
beneath the machine & likewise pivoted at Back, the outer ends of swinging arms are
coupled together by an adjustable Link, so that any desired strain can be put on the
saw without decreasing the power of the Machine. To change from Circular sawing
to Jig or Frett sawing, pull over the quadrant E as far as possible, when the Circular
saw will disappear below the Table leaveing the surface clear slip on the Link
connecting disc, H, with its vertical saw spindle, connect Top end of saw with
swinging arm & all is ready for work. In cutting out Felloes of Wheels or any
thing thick where there is dificulty in holding the wood down an arm is brought over
the machine with an adjustable guide at back of Saw which can be set to allow the
wood sufficient room to pass under & yet prevent it riseing with the return stroke of
the saw.
The main driveing wheel is peculiarly constructed so as to carry a Flat Belt for
driveing the Saw & a Round Belt (or gut) for driveing the Lathe & Drill spindle,
where a variety of speeds are required. Gis a Fly Wheel with a flat face on outer
edge extending some half way across or thereabouts according to the width of Belt
employed the other side being stepped & V Grooved to carry the Round Belt, the
speed Cone of Lathe Head & Drill Spindle being stepped & groved to match. Cast
with the Fly Wheel or fastened beside it on the end of Crank shaft is a Gear Wheel Q.
Attached to the standard carrying the Fly wheel is a suitable bearing through
which passes a shaft, haveing at one end a wheel R Gearing into wheel Q and at
the outer end a Crank & Handle by which it is turned either as an auxilery to the
man Treadling or to entirely drive the machine when Treadling is inconvenient. In
the drawing the wheels are shown in gear kept in position by a pin X passing through
the bearing into a grove turned in handle shaft, to throw the wheels Q & R out of
Gear pin is withdrawn handle shaft is moved horizontally to the left & pin X
Reinserted in another Grove turned in handle shaft a suitable distance to the Right.
