PROVISIONAL SPECIFICATION left by the said John Ruscoe at the Office of
the Commissioners of Patents on the 19th October 1883.
JOHN RUSCOE of the Albion Works, Hyde in the County of Chester, Engineer.
A NEW OR IMPROVED MACHINE FOR FACING THE ENDS OF, AND TURNING, OR
BORING GAS RETORT MOUTHS, PIPES, OR VALVES AND THE LIKE, WHICH ARE OF D,
OVAL, OR ANY OTHER SHAPE OR SECTION THAN ROUND.
The object of my Invention is to construct a machine for facing the ends of, and
turning, or boring gas retort mouths, pipes, or valves and the like, which are of D,
oval, or any other shape or section than round, by revolving the tool or the piece
to be faced, turned, or bored
The machine consists of a frame or support and a "duplicate" or "former" to
suit the articles to be faced: this "duplicate" has spur teeth on the inner or outer
surface and a hollow cam is cast or made in or on it. The driving shaft passes
through and has a bearing in a slotted bracket: on the inner end of this shaft a
bowl may be held to work in the hollow cam of the "duplicate" or "former" and
a pinion is keyed or secured to the shaft: the cutting tool is fixed to a sliding
block in the slotted bracket. This bracket is free to turn on a shaft which is
secured in the frame which carries the machine.
When motion is communicated by hand or power to the driving shaft the pinion
revolves and travels over the "duplicate" and transmits a rotary motion to the
slotted bracket in which the cutting tool is held as described.
The bowl on the end of the driving shaft rests in and is guided by the hollow
cam or path in the "duplicate" which forms an end bearing for the shaft.

page_text: In applying my Invention to face the end of a retort mouth, or similar article I
fix in the retort mouth by bolts or otherwise one part of the facing machine:--the
"duplicate" is secured to this portion: the slotted bracket is keyed or secured to a
shaft which has its bearing in the stationary or fixed part of the machine and
passes through the "duplicate"
"
The cutting tool follows the path given to it by the "duplicate" and in order to
give the tool an automatic feed the block to which it is secured may have a screw
passed through it which has bearings at the ends of the slotted bracket and is
provided with a star wheel turned by any convenient stud fixed to the duplicate
or other stationary part of the machine.
This machine may be applied to retorts, pipes, or other articles when fixed in
their places or it may be used for the doors of retort mouths and such like pieces:
it can also be used on machine tools.

"A NEW OR IMPROVED MACHINE FOR FACING THE ENDS OF AND TURNING OR
BORING GAS-RETORT MOUTHS, PIPES OR VALVES AND THE LIKE, WHICH ARE OF D,
OVAL, OR ANY OTHER SHAPE OR SECTION THAN ROUND."
The object of my Invention is to construct a machine for facing the ends of and
turning or boring gas retort mouths, pipes or valves and the like, which are of D,
oval, or any other shape or section than round, by revolving the tool.
The machine consists of a frame or support and a "duplicate" or "former” to
suit the articles to be faced; this duplicate has spur teeth on the inner or outer
surface and a hollow cam is cast or made in or on it. The driving shaft passes
through and has a bearing in a block in a slotted bracket: on the inner end of this
shaft a bowl may be held to work in the hollow cam of the "duplicate" or
"former" and a pinion is keyed or secured to the shaft: the cutting tool is fixed
to the sliding block in the slotted bracket: This bracket is free to turn on a shaft
which is secured in the frame which carries the machine.
When motion is communicated by hand or power to the driving shaft the pinion
revolves and travels over the "duplicate' and transmits a rotary motion to the
slotted bracket in which the cutting tool is held as described.
"
The bowl on the end of the driving shaft rests in and is guided by the hollow
cam or path in the "duplicate" which forms an end bearing for the shaft.
In applying my Invention to face the end of a retort mouth or similar article I
fix in the retort mouth by bolts or otherwise one part of the facing machine:-the
duplicate" is secured to this portion: the slotted bracket is keyed or secured to a
shaft which has its bearing in the stationary or fixed part of the machine and
passes through the "duplicate."
The cutting tool follows the path given to it by the "duplicate" and in order to
give the tool an automatic feed the block to which it is secured may have a screw
passed through it which is provided with a star wheel turned by any convenient
stud fixed to the "duplicate" or other stationary part of the machine.
This machine may be applied to retorts, pipes or other articles when fixed in
their places or it may be used for the doors of retort mouths and such like pieces:
it can also be used on machine tools.
And in order that my Invention may be fully understood and readily carried
into effect I will proceed to describe the accompanying Sheet of Drawings,
reference being had to the figures and letters marked thereon.
Fig. 1 is a front elevation and Fig. 2 is a side elevation of my improved machine
fitted to a retort mouth.
a is the mouth of a gas retort in which is fixed the frame b by screws c: dis
the duplicate or former having spur teeth and a hollow cam ƒ inside its rim: 9 is
a slotted bracket keyed on a shaft h that passes through a boss that connects the
frame b and former d: the shaft h is partly conical and the wear is taken up by
lock nuts h¹. In the bracket g slides the block i in which is fitted the tool holder j
which carries the facing tool k. The holder j is traversed in the block i by a
screw that is actuated automatically by a star wheel that comes in contact
with a stud on the former d at each revolution of the block i. In the block i is a
bearing for the driving shaft l on which is a pinion m that gears into the spur
teeth on the former d and at the end of the shaft is a bowl n that fits and
travels in the cam f and forms a bearing for the shaft. The bowl n in the cam f

page_text: guides the shaft 7 and block i and keeps the pinion m in gear with the teeth e.
When the shaft is turned by the handle o the pinion m (gearing into the teeth 6)
moves the bracket g and block i and the tool k is thus caused to cut or face the
mouth of the gas retort a.
Having stated the nature of my Invention and described the manner of
performing the same
I declare that I claim
1. The improved machine for facing the ends of and turning or boring gas retort
mouths, pipes or valves and other surfaces which are of D, oval, or any shape or
section other than round, substantially as herein described and as shown.
2. The combination with the former d having teeth e and a cam f of the bracket g
carrying the sliding block i shaft j, pinion m, and tool k as and for the purposes.
herein described and as shown.
In witness whereof I the said John Ruscoe have hereunto set my hand and seal
this sixteenth day of April, One thousand eight hundred and eighty four.
JOHN RUSCOE (L.s.)
