Year: 1861

page_text: LETTERS PATENT to Bernard Hudson, Gentleman, residing at No. 25,
Gloucester Crescent, Regent's Park, London, County of Middlesex, for
the Invention of "AN IMPROVED MACHINE FOR APPLYING STEAM IN A
MANNER TO CAUSE DIRECT ROTATION."-A communication from abroad
by Messrs. Antonio Grande Giovanni Battista Olivieri and Lorenzo
Morigiardino, of Turin, Italy
Sealed the 15th August 1861, and dated the 16th May 1861.
COMPLETE SPECIFICATION filed by the said Bernard Hudson at the Office
of the Commissioners of Patents, with his Petition and Declaration.
on the 16th May 1861, pursuant to the 9th Section of the Patent Law
Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I. BERNARD
HUDSON. Gentleman, residing at No 25, Gloucester Ciescent. Regent's Park,
London, County of Middlesex, send greeting.
WHEREAS I am in possession of an Invention for "AN IMPROVED MACHINE
FOR APPLYING STEAM IN A MANNER TO CAUSE DIRECT ROTATION," and have peti-
tioned Her Majesty to grant unto me, my executors, administrators, and
assigns. Her Royal Letters Patent for the same. and have made solemn
declaration that it has been communicated to me from abroad by Messrs
Antonio Grande Giovanni Battista Olivieri and Lorenzo Mongiardino, of
Turin, Italy.
NOW KNOW YE, that 1, the said Bernard Hudson, do hereby declare
that the following Complete Specification under my hand and seal fully
Price 8d.1

page_text: describes and ascertains the nature of the said Invention, and in what manner
the same is to be performed. in and by the following statement, reference
being had to the Drawings hereunto annexed, and to the letters and figures
market thereon, that is to say:
10. this wheel is
1, 2, 3. & 4: those
The Invention consists in a circular machine or case, represented in the
Drawing as No 12, in which is fixed a solid iron ring at about the half of its
circumference No. 13. the use of this ring being to force the current of steam
which issues from the tube No 14 always in the same direction; this ring is
fixed to the machine or case by the screws No. 22 An excentric wheel
No. 6 is placed in this case and fixed to the axle No
furnished with four articulated teeth, represented by Nos
teeth, being diametrically opposite to each other, close the space between the
two circles No 26. so that they form an obstacle to the steam contained in
the tube No. 14. and produce thus a rotary movement upon the axle of the
eccentric wheel: these teeth are fixed to the wheel by means of pivots No. 25,
and in such a manner as to cause a rotary movement; they are two by two
opposite to each other and connected by two lever arms No. 18. which are
fixed on one side of the back of the interior of the tooth No. 17, and on the
other to two parallels No. 19 round the axle No. 10: these parallels are
joined at their extremities by two semicircles, so that the movement of a tooth
on one side produces the contrary movement on the opposite tooth. When not
in motion the wheel will always show two teeth open and two teeth shut, and
when in motion the tooth indicated as No. 1 takes the place of that marked
No. 2: the same thing takes place with the tooth No. 4. which takes the
place of No. 1. and No 3 takes the place of No 4. The motion of the wheel
caused by the current of steam introduced into the receptacle No. 26 causes
the tooth No 2 to meet the wheel No. 5, which encounter shuts the tooth
and causes a rotary movement to the wheel on its axle, as indicated in No 11,
consequently the movement produced by the lifting and falling of the teeth is
always at right angles, and the teeth thus cause the pivot No. 17 to perform a
quarter of a circle before attaining the position indicated by the shut teeth
Nos. 3 and 4: these teeth are divided lengthways into two parts, joined
together by means of four strong screws: some tow is placed in the space
No. 23, which, pressing against the concave top surrounding the space No. 26,
obliges the teeth to act as pistons and replaces a cylinder It will be under-
stood from the above description that the steam introduced to the tube
No. 14 is always sufficiently concentrated to act upon the teeth, either shut or
open, which much necessarily cause the rotary movement indicated. The
mechanism is kept well greased in the interior by means of two receptacles for

page_text: oil. No. 8 and 9. which are fixed on the exterior of the machine or case. The
first of these receptacles. No. 8, introduces oil by the small tube, No. 24, to the
extremity of the teeth, and the second. No. 9. distributes the oil over the surface
of the wheel before indicated.
In witness whereof, I. the said Bernard Hudson. have hereunto set my
hand and seal, this Twenty-fifth day of April, in the year of our Lord
One thousand eight hundred and sixty-one.
(L.S.) BERNARD HUDSON.
