IMPROVEMENTS IN APPARATUSES FOR CONVERTING RECIPROCATING INTO ROTARY. MOTION
Year: 1858

page_text: Sealed the 28th June 1859, and dated the 30th December 1858.
PROVISIONAL SPECIFICATION left by the said William Burgess at the.
Office of the Commissioners of Patents, with his Petition, on the
30th December 1858.
I, WILLIAM BURGESS, of the firm of Burgess and Key, of Newgate Street,
in the City of London, Agricultural Engineers, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN APPARATUSES FOR CONVERTING
RECIPROCATING INTO ROTARY. MOTION," (communicated to.me by G.. Bancker,.
residing in New York,) to be as follows:-
This Invention consists in the employment of a sliding clamping block on a
sliding rod, in combination with an alternating. clamping lever worked. by a.
reciprocating rod, in such manner that at each alternation of the reciprocating
rod the clampers of the clampling lever take hold of the opposite sides of an

page_text: endless belt to continue its motion, and thus impart rotary motion to a shaft or
shafts, pulley or pulleys, over which the belt is passed.
The Invention also consists addition to a treddle to drive the reciprocating
rod, of an endless reacting spring to the under side of the foot rest of the
treddle, so that when the toe of the foot rest is depressed, and on the giving
back of the pressure of the foot, the spring will cause the rest to follow the
foot up.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Burgess in the Great Seal Patent Office on the
30th June 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
BURGESS, of the firm of Burgess and Key, of Newgate Street, in the City of
London, Agricultural Engineers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirtieth day of December, in the year of our Lord
One thousand eight hundred and fifty-eight, in the twenty-second year of Her
reign, did,. for Herself, Her heirs and successors, give and grant unto me, the
said William Burgess, Her special licence that I, the said William Burgess, my
executors, administrators, and assigns, or such others as I, the said William
Burgess, my executors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at all times thereafter during
the term therein expressed, should and lawfully might make, use, exercise,
and vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN APPA-
RATUSES FOR CONVERTING RECIPROCATING INTO ROTARY MOTION," (a communica-
tion from G. Bancker, residing in New York,) upon the condition (amongst
others) that I, the said William Burgess, my executors or administrators, by
an instrument in writing under my, or their, or one of their hands and
seals, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and cause
the same to be filed. in the Great Seal Patent Office within six calendar
months next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said William Burgess, do hereby declare the
nature of the said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following state-

page_text: ment thereof, reference being had to the Drawings hereunto annexed, that
is to say:
This Invention consists in the employment of a sliding clamp block on a
sliding rod, in combination with an alternating clamping lever worked by a
reciprocating rod, in such manner that at each alternation of the reciprocating
rod, the clampers of the clamping lever take hold of the opposite sides of an
endless belt to continue its motion, and thus impart rotary motion to a shaft
or shafts, pulley or pulleys, over which the belt is passed.
The Invention also consists in the addition to a treadle to drive the recipro-
cating rod, of an elastic reacting spring to the under side of the foot rest of
the treadle, so that when the toe of the foot rest is depressed, and in the
giving back of the pressure of the foot, the spring will cause the rest to follow
the foot up.
Figure 1 of the accompanying Drawings is an end, Figure 2 a front, and
Figure 3 a sectional view of the machinery for obtaining rotary from recipro-
cating motion. A is a block, shewn detached and in plan at Figure 4, which
slides along a grooved rod or shaft B; this block A is jointed to a frame D,
the sides of which are connected together by two rods C, C; the frame D
forms the clamping lever, and is jointed at one end to a rod E, to which
reciprocating motion is communicated from a treadle or otherwise; F is an
endless strap, passing round pulleys G, G, and between the rods C, C, and the
block A; one of these pulleys is keyed on a shaft H, to which the rotary
motion is communicated, the other on the lower part of the shaft B. As the
block A travels along the shaft B, the endless strap is clamped alternately by
one of the rods C, C, pressing it against the block A, whereby the belt is made.
to travel in one direction, and to impart continuous rotary motion to the
shaft H; a fly wheel I regulates the motion.
Figure 5 is a view of a treadle the Inventor prefers to employ for com-
municating a reciprocating motion to the rod E. K is a foot resting on a
treadle L, which is hinged at one end to a bracket attached to a floor or bed,
and jointed at the other to the rod E; M is a reacting spring, which is
connected to the under side of the treadle at a, and to the floor at b.
And having now described the nature of the said Invention, and in what
manner the same is to be performed, I declare that I claim,-
First, the employment of a sliding clamping block on a sliding rod in
combination with an alternating clamping lever worked by a reciprocating rod,
for obtaining rotary motion, as berein-before described and illustrated in the
accompanying Drawings.

page_text: Second, the adaptation of an elastic reacting spring to the under side of a
treadle, as herein-before described.
In witness whereof, I, the said William Burgess, have hereunto set my
hand and seal, this Thirtieth day of June, One thousand eight hundred
and fifty-nine.
W. BURGESS. (L.S.)
