PROVISIONAL SPECIFICATION.
Improvements in and relating to Toothed Gearing.
I, HENRY PHILLIPS RAYMOND, of Honey Corse, St. Clears, South Wales,
Gentleman, do hereby declare the nature of this invention to be as follows:-
This my invention relates to a new mechanical movement, and it has for its
object, the provision of simple means of converting a reciprocating movement into
a rotary motion.
The invention consists of a pinion which is mounted upon a shaft, and which has
teeth around half of its circumference only. A loop (connected at one end to the
reciprocating rod) passes over the pinion and is formed upon its opposite inner
longitudinal sides with opposite racks which engage alternately the teeth of the
pinion which is rotated thereby when the loop is reciprocated.
Dated this 29th day of December 1892.

COMPLETE SPECIFICATION.
Improvements in and relating to Toothed Gearing.
I, HENRY PHILLIPS RAYMOND, of Honey Corse, St. Clears, South Wales,
Gentleman, 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 :-
This my invention has reference to certain improvements in and relating to
toothed gearing.
My invention will be found especially useful in parts of machinery where it is
required to convert rotary motion into reciprocating movement.
In the drawings hereunto annexed,
Fig. 1., is a side view of my invention;
Fig. 2., is a sectional end view; and
Fig. 3., is a detail view illustrating one of the teeth or pins hereinafter
referred to.
In carrying out my invention, I provide a link A which may be formed integral
with, or be connected to a rod B; one of which may be connected to each end of
the link if desired. A roller C, having a flange D, is fitted to travel freely in the
link A and is mounted upon a shaft E; a collar F being preferably fitted upon the
shaft against its shoulder G, as shewn. A collar or disc H is fitted on the opposite
side of the roller to form a flange on that side of the link.
A tooth-wheel I is secured to the shaft adjacent to the collar H and is held in
place by a collar J and pin K. This tooth-wheel. has teeth around a portion only
of its circumference, and said teeth engage projecting pins L on the side of
the link.
The pins Leach have preferably a collar M, (Fig. 3.) upon them, and said collar
is secured in place by a washer N and pin O.
If desired, I may construct the link A of two thin metal plates having two
parallel rows of pins arranged between them and holding the plates together. In
this form, the tooth-wheel is arranged between the two metal plates, as will be
understood.
When the shaft and tooth-wheel I is rotated in the direction indicated by the
arrow, for instance, the tooth P will have disengaged itself with the pin Q, and
D

carried the link as far as possible in the direction indicated by the arrow R. The
tooth S will now engage the pin T and the link will be carried in the opposite
direction until the tooth P. disengages itself from the pin U, and the tooth S
engages the pin V. By this means a reciprocating movement of the link and its
connecting rods is attained.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is-
The hereindescribed method of and means for converting rotary movement into
, reciprocating motion; the means consisting of a tooth-wheel having teeth around a
portion of its circumference and adapted to engage alternately two parallel rows of
pins arranged upon a link, substantially as and for the purposes hereinbefore set
forth and illustrated in the drawing hereunto annexed.
Dated this 28th day of October 1893.
