Year: 1885

page_text: I DANIEL DIMOND WHITE residing at 8 James. Street Drypool in the town of
Kingston upon Hull being employed as Foreman Fitter at Messrs Earles Ship-
building and Engineering works Hull do hereby declare.the nature of my invention
for A PLANING MACHINE. FOR ANGLE BARS- PREVIOUS TO CAULKING. to be.as
follows:-
This machine consists of cast metal frames or supports with grooved rollers
arranged in pairs, each pair having a driving and a friction roller, The lower
rollers being groved to admit the angle bar and fitted with adjustable sections to
admit bar, or any size angle varying from 14" x 11" to 3" x 4" a fixed tool
box or slide rest is fitted with tools set to the necessary bevel to finish the work
at one setting. A train of wheels gearing actuates the rollers which in turn carry
forward the angle bars to the cutting edge of the tools, The brackets carrying the
top rollers is made to lift with suitable gear to receive any sized angle and also be
automatically controlled to insure the friction rollers carring forward the work.
The top brackets for carrying the rollers is jointed so as to lift radially round the
loose pinion A and thus always is in gear at whatever height the rollers inay stand
By reversing the rollers the machine can be so arranged that angles may receive
the cut from above instead of below.

page_text: I DANIEL DIMOND WHITE of 8 James Street Drypool Engineer 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:
My Invention has for its object the arrangement and construction of a machine
adapted for planing both edges of angle bars simultaneously without the necessity
of any previous fixing or clamping of the bars and also without any traversing
table or traversing tool box as in ordinary planing machines.
This machine consists of cast metal frames or supports with grooved rollers
arranged in pairs each pair consisting of friction rollers. The lower rollers are
grooved to admit the angle bar or any sized angle varying or ranging from 1 inch
by 2 inch to 3 by 5 inches or thereabouts. Two or more fixed tool boxes
or slide rests fitted with four tools being set to the necessary bevil to finish the
work at one setting.
A train of wheels gearing with one another actuates the rollers which are thereby
caused to carry forward the angle bars to the cutting edges of the tools. The
brackets carrying the top rollers are made to lift with suitable gear to receive bars
or any sized angle required and also to be automatically controlled in order to
ensure the carrying forward, of the work by the friction rollers. The top brackets
for carrying the rollers are jointed so as to lift radially with a loose pinion and be
always in gear at whatever height the rollers may stand. The machine can be so
arranged that the angles of the bars may receive the requisite cut from above
instead of from below.
In order. that my Invention, may be fully understood and readily carried into
effect I will describe it more particularly by the aid of the accompanying drawings
in which is represented a machine constructed in the manner, above, referred to.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a side elevation of the machine, Fig. 2 a plan or horizontal view, and
Fig. 3 an end view of the same. Fig. 4 is a partial end view showing a pair of angle
bars and a tool box with cutting tools. In these several figures the same letters of
reference indicate corresponding parts.
A A are the cast metal frames or supports with necessary bearings and facings,
Brackets B carry the driving pullies and worm shaft which actuates or drives the
worm wheel C with the shaft to which it is keyed. On this shaft are arranged
three rollers No 1. 2 and 3 and also on the same shaft a pinion D gears into and
works the loose pinion E.
This pinion E gears into and works the pinion and shaft F with rollers which
are duplicates of Nos 1. 2 and 3, and also works the loose pinion G which works
(or drives) the pinions H and I which are keyed on the shafts of the top rollers
and work them.

page_text: The top rollers are carried by arms or brackets which are hinged (as shewn in
the drawings) to a rigid spindle which acts as a stay for the top of the machine
and on which the loose pinion G works. By this arrangement of; hinging, the top
rollers and their driving pinions may be lifted to different heights as required and.
always remain in gear with the loose pinion G, as they work at the same radial
distance therefrom.
The pressure exerted on the top rollers in order to ensure sufficient friction
between the rollers and the angle bars is as follows.
Two arms K K are fixed to the top roller shafts and connected to the same pin
on the lever L having its fulcrum at L¹. The pressure is applied at the end of the
lever L by means of the nut and screw M with hand wheel and the whole is
supported by. a bracket fixed about half way on the screw spindle: springs are
fitted above and below the spindle the lower one to take the reaction or thrust of
pressure on the lever L and the upper one to neutralize the shock of the top roller,
the rods and lever dropping when the bar has passed away from the rollers. N acts
as a stay and shaft for loose rollers duplicates of Nos 1. 2 and 3 which serve to
guide the angle bar to the friction rollers.
The lower rollers are all fitted with side springs for self adjustment in case of a
bent bar being passed through the machine. At O is a stiffly bracketed plate
which carries tool boxes and to which is also attached quadrants with levers which
carry a small roller with collars to guide the angle bar.
This roller takes the upward thrust of pressure exerted by the tools and ensures
an equal cut.
The collars take the side thrust of the tools and assist in straightening a bent bar.
Allowance for adjusting to varying thickness of angle bars is made by the roller
working through a small arc.
Tool boxes P carry the cutting tools and are so arranged as to swivel to a small
extent in order to take cuts simultaneously off both flanges of an unequal sided
bar instead of using separate tool holders.
In some cases separate tool holders and boxes are advantageous.
In the machine as, herein before described it will be seen that the angle bar or
bars is or are carried forward to the cutting tools by means of strong friction rollers
driven by sufficient power and gearing in order to overcome the resistance offered
by the process of taking a cut off both flanges of a bar or bars simultaneously.
The pressure required for obtaining the necessary friction between the rollers and
the angle bar or bars is applied as described by means of drag rods or arms and a
lever with spring reaction. The rollers are driven by a suitable train of gearing
which gives them equal periphery speed or traverse, and also gives to each pair of
rollers the proper motion for working the angle bar in one forward direction.
The following are advantages belonging to a machine constructed in the manner
herein before described.
1. By the use of rollers as described the work is forwarded to the cutting tools
without previous fixing or clamping by means of bolts and plates as has to be done
in other planing machines.
2. The machine is strictly speaking stationary and self-contained, as beyond the
gearing there is no traversing table or traversing tool box which runs backwards
and forwards as in other planing machines, and consequently very little space
is occupied.
3. Two angle bars with flanges of varying widths can be worked at the same
time and can be arranged to pass through the rollers in any sectional position by
grooving or turning the rollers to suit, viz.
The bar may be worked on the back or side or in any angular position by turning
the rollers in the latter case as V male and female i.e. the top rollers to grip the
outside angle and the bottom rollers to grip inside or vice versa; and the tools may
be arranged to cut on the top or on the bottom as may be convenient in any of the
aforementioned cases,

page_text: 4. The rollers No 192 and 3 are turned to suit the inside bevil of any angle and
are arranged to adjust themselves by means of the side springs to a bent angle when
passing through the machine, this being a great advantage and effecting a saving.
of labour inasmuch as angle bars have to be straightened before being fixed on
ordinary planing machines..

5. The pressure is exerted automatically by means of the springs on the screw
spindle Min combination with the hinged pinions so that a lumpy or uneven angle
can relieve itself when passing through the rollers, the pinions remaining in truc
gear all the while-Likewise the top rollers will not jar on the bottom rollers when
a bar has passed through, the weight of the top gear being taken by the upper or
counterbalance spring on the screw spindle.
6. An adjustable side roller is or may be fixed between the pairs of rollers thus
combining to effect the straightening of a bent bar when passing through the
machine, so that a crooked bar will leave the machine in a straighter condition than
when it entered, the tendency of the action of the machine being to draw bars into
line again.
7. Two machines can be coupled together without any alteration in the arrange-
ment of either, thus securing a more powerful combination:
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
I do not claim any of the parts of the machine separately, or otherwise than as
working in combination for the purpose or purposes described, but I declare that
what I claim is
The arrangement and combination of the whole of the parts constituting the
machine adapted for planing both edges of angle bars simultaneously, in the manner
and by the means substantially as described.
