PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Converting Reciprocating into
Intermittent Rotary Motion.
1, CHARLES CASIMIR BARTON of the Windsor Hotel, Edinburgh, North Britain,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to that class of mechanical movements in which reciprocating
is converted into intermittent rotary motion.
The invention consists of an improved construction and arrangement of parts which
not only allow for such conversion but also have the additional advantages of allowing
for intermittent and irregular length of reciprocating movement and locking of the
rotary parts except during such time as they are being directly operated upon.
The nature of my invention may be briefly described by stating that the driving
shaft of the rotary part of the movement is actuated by an angular plate or toothed
wheel which is intermittently rotated by the reciprocating parts which operate upon
opposite sides of it and are so arranged that the plate or wheel is alternately held upon
one side until the reciprocating part is about to operate upon the other side. One or
more of the angular plates or toothed wheels may be employed and when two or more
are used either or all may be caused to actuate rotary shafts and connected gear.

Intermittent Rotary Motion.
I, CHARLES CASIMIR BARTON of the Windsor Hotel, Edinburgh, North Britain,
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:
This invention relates to that class of mechanical movements in which reciprocating
is converted into intermittent rotary motion.
The invention consists of an improved construction and arrangement of parts which
not only allow for such conversion but also have the additional advantages of allowing
for intermittent and irregular length of reciprocating movement and locking of the
rotary parts except during such time as they are being directly operated upon.
The nature of my invention may be briefly described by stating that the driving
shaft of the rotary part of the movement is actuated by an angular plate or toothed
wheel which is intermittently rotated by the reciprocating parts which operate upon
opposite sides of it and are so arranged that the plate or wheel is alternately held upon
one side until the reciprocating part is about to operate upon the other side. One or
more of the angular plates or toothed wheels may be employed and when two or more
are used either or all may be caused to actuate rotary shafts and connected gear.
In order that my invention may be clearly understood reference is made to the
accompanying drawings in which :
Fig. 1 represents a side elevation partly in section of the reciprocating mechanism
and the arrangement of parts for converting the movement thereof into intermittent
rotary motion.
Fig. 2 represents a front view partly in section of the reciprocating and intermittent
rotating part.
Fig. 3 is a like view with the parts in a different or alternate position.
Fig. 4 is a plan view on the line xx, of Fig. 2.
5
Fig. represents a front elevation of the arrangement when a single reciprocating
arm is used to act alternately upon two rotary plates or pieces and alternately to hold
same..
Fig. 6 is a like view with the parts in a different or alternate position.
The reciprocating parts or cranks A may be in the form of a single bent and slotted
sheath surrounding the frame B, or two separate rods or cranks or reciprocating arms
may be used, or a single arm may be employed to operate two or more of the rotating
parts.
In Figs. 1. 2. 3 and 4 are shown a single rotating part C mounted upon shaft b, a
one end of which is carried in bearings in frame B. Part C is here shown as consisting
of a three-toothed wheel, the teeth of which when at right angles to the plane of
motion of the reciprocating part A being of sufficient length to extend out into said
plane of motion.

page_text: Referring to Fig. 2 let it be assumed that the reciprocating part A is travelling in
the direction of the arrow when there will be no motion of wheel C until part a comes
in contact with tooth d, which it will carry with it giving a partial rotation to wheel C
as part a will have travelled far enough to permit d² to move and the wheel will then
be in the position shown in Fig. 3 where it will be temporarily locked against movement
by reason of teeth dd being in contact with the inner face of part a of the sheath A.
On the reverse motion of the sheath A, as indicated by the arrow in Fig. 3, teeth dd
are froo of part a before or just as part a' strikes tooth. In Fig. 5 the discs or
pieces C are about to be operated by slotted rod A, which is supposed to be moving in
the direction of the arrow, part a being just about to strike and move point d while
point a' has just released the face so that as d is moved and locked by a
between d d² its motion may be transmitted through gear D and point brought into
the position shown in Fig. 6 ready to be acted upon when part a' is brought against
it on the return stroke of rod A. In this construction gear D may be used to impart
the intermittent rotary motion to the desired mechanism either alone or in conjunction
with shafts bb as may be desired.
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
claim is :-
1. In apparatus for converting reciprocating into intermittent rotary motion the
combination with the reciprocating part of an angular piece or toothed wheel adapted
to be operated thereby alternately upon opposite sides as set forth.
2. In apparatus for converting reciprocating into intermittent rotary motion the
combination with the reciprocating part of two or more regular pieces or toothed
wheels and suitable connected gear substantially as set forth.
3. In apparatus for converting reciprocating into intermittent rotary motion a
reciprocating part or.crank so slotted or formed as to alternately act upon the opposite
sides of an angular piece or toothed wheel and to alternately hold the opposite sides of
said piece or wheel from rotation as described.
4. In apparatus for converting reciprocating into intermittent rotary motion a
reciprocating part or crank so slotted or formed as to alternately act upon separate
angular pieces or toothed wheels and to alternately hold same from rotation as
described.
