Improvements in Disengaging Mechanism, applicable to the Slip
Gear of Steam Engine Cut-off Valves, Traps Employed in Pigeon
Shooting, and other analogous purposes
] GEORGE PALLY of Bank Top Mills, Preston, in the County of Lancaster,
Cotton Spinner, and Manufacturer, 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
In
This invention relates to improvements in disengaging mechanism applicable to
the slip gear of steam engine cut-off alves and to other analogous purposes
carrying out my sud invention I cinplov, mounted in suitable end beings-two
horizontally disposed hollow cylinders one of which is a hxture and the other
1otatible the cylinders being so arranged that the cylinder not fixture may rotate
within or outside of the fixed cylindei as hereinafter explained The peripheries
of the inner and outer cylinders are each pierced with a round hole the sud holes
as the rotatable cylinder moved round being brought opposite to each othe
Suntounding or embi icing the periphery of the outer cylinder.
-so as to be movable
rotatably thereon-is the chip or eye end of an aim or lever Over the upper part
of the said clip or eve is a funnel mouthed opening in the same plaue as the two
holes in the inner and outer cylinders A spherical metal ball is dropped into the
funnel-mouthed opening and the parts in then normal position are so it inged that
the opening in the lever stands opposite to the hole in the outer cylinder the ball
thus occupying a position as to its lower half within the hole in the outer cylinder
and as to its upper half within the hole in the lever Hence in the position
described the level is locked or engaged with the outer cylinder and if the sud
outer cylinder be moved round the levci also will be moved round with it and when
the hole in the outer cylinder is brought opposite to the hole in the inner cylinder
the metal bill will slip through into the interior of the inner cylinder thus releasing
or disengaging the lever from the outer cylinder ind allowing it-by the pull of a
spring on weight-to suddenly fly back to its origin 1 or ormal position and thus
to bing about the cut-off or other effect I he metal ball may be arranged to run
down an incline within the interior and to the outside of the inner cylinder and to
be returned to its former position in the lever eye in any suit ible manner or another
ball may be automatically caused to take its place The inner cylinder may on
the other hand be rotatable and may have attached to one of its outer ends an arm
connected in the case of a steam engine-to the governor the outer cylinder being
a fixture and the lever herein befor referred to being connected to the cut-off valve
mechanism the disengaging or releasing effect occurring when the governor has
pulled round the inner cylinder so as to have brought the holes (in the inner and
outer cylinders) opposite to each other and therefore to have allowed the metal ball
to slip through them as herembelort described Another purpose to which for
example my invention is applicable is the pulling of traps employed in pigeon
shooting In this case I employ a number or series of levers standing s de by side
upon the outer cylinder with in inner not table cylinder as first hereinbefore
described and by means of a teetotum or other device 1 cause a single metal ball
to be delivered or directed indiscriminately into one or other of the funnel mouthcd

The inner cylinder in this case is stationary and the outer
one rotatable the said outer cylinder having on one end a weighted arm or lever
in conjunction with a releasing trigger arrangement
The accompanying diawings illustrate the nature of my said invention and shew,
as regards Figs 1 to 5 inclusive, the arrangement of the apparatus hereinabove
described as adapted to the pulling of traps employed in pigeon shooting

Fig 2 a side view partly in section,
Figs 3 and 4 detail view of part of a teetotum device I preferably employ,
and
Fig 5 an end view of a collar and the end of a lever mounted on the projecting
end of the outer cylinder as hereinafter described
The succeeding figures illustrate a method of applying my invention to the slip-
gear of steam engine cut-off valves
and
Fig 6 being a transverse sectional view and
Figs 7 and 8 end view of parts of the apparatus I employ for this purpose,
Fig 9 bunga sectional longi udinal view showing the general arrangement of
the apparatus
In the rangement shown in Fig 1 to inclusive, a is the outer cylinder
rotatable upon the fixed inner cylinder b, the litter being fastened at its left-hand
end in the side standard d and the outci cylinder a being capable of rotating
within the end beating e' in the side stand ird d' on the right hand as well as upon
the fixed inner cylinder b e are holes in the outer cylinder a and e¹ e¹ in the
inner cylinder b fte levers each connected at its lower end by a cord g to one
of the several pigeon trap
(In Fig 2 only two of five levers fare shown in order
that the interior relation of the cylinders a and b may be more clearly seen) f15
the eye or clip of the lever and 2 the funnel-mouthed opening into which the
ball is dropped locking the end or clip of the lever with the outer rotatable
cylinder a (as shown at Fig 1) 2 is a coiled spring pressing at one end against a
pin projecting from the fixel side plate and at its other end on a pin ¹ projecting
hom the inner side of collar fast upon the projecting end of the outer rotatable
cylinder a m is a lever having side clips m¹ m which embrace the sides of the
collar which has lip or detent catch ¹ nis part of the outer rotatable
cylinder a and has upon it two catches or lips n¹ and n² the latter projecting further
out than π' The coiled sprin, holds the outer cylinder a and the lip n' up
against another lipo on the pivoted level of which can only be pulled back as fai
as the stop o The lever o is provided with a back spring o³ to piess or push it
towards the axis of the cylinders Thus if the lever o¹ be pulled outwardly by
means of the handle p and 1od p' clear of the stop n the outer cylinder a under
the influence of the spring will move round until the stop 2 (which projects
further out) meets the lip o Meanwhile the outer cylindei a will have cairied
round with it the particular level fee Fig 1) which for the time being has
received the metal ball the said ball when it reaches the hole e' (see Fig 1)
dropping therethrough thereby releasing the lever f which returns to its former
position against the stop 1od f3 by the pressure of a flat spring q The ball h finds
its way along a loping channel (not shewn at Fig 2) into a box whence it
may be removed by hand and placed in the upper circular tray s of the tectotum
mechanism Ihe trays is centrally fast upon the vertical spinale tas also the
circular undc tray u The trays has an outer opening s' and the under trav u an
inner opening u¹ Below the tray u is a stationary tray v (shewn detached at
Fig 3) having several sloping compartments with holes vv and below the stationary
tray is a plate w (shewn detached at big 4) having sloping grooves w¹ w¹ which
lead to the funnel-shaped mouths 1212 of the several levers below When the
spindle t and trayss and u are spun round the ball is placed in the upper tray s
and gradually finds its way through the holes into the tray u below and through the

page_text: hole into one or other of the compartments of the tray and through one of
the holes into one or other of the ducts or passages w¹ 10¹ and so on into one of
the upper ends f2 of the lever> ft are regulating screws for adju ting the
level of the teetotum mechanism and y y are spirit levels The lever m is used for
bringing back the cylinder a and its detent n under the catch o after the release
of a lever fas above described
I have described my invention as adapted to a multiform arrangement that is to
say with five levers but it will be apparent that disengaging mechanism working
on the same principle but having only one such lever and without the teetotum
mechanism may readily be arranged
b 13 a
In the apparatu shown in Figs 6 to 9 inclusive, a is an inner rotatably movable
cylinder actuated from the engine governor through the medium of the rod e and
the lever (see Fig 8) The cylinder a has a hole d bored through it
cylinder which moves e sily on the inner cylinder a and is connected to an eccentric
on the main driving shaft y of the engine by means of the lovers h and 2 (see
Fig 7) c is an outer eye or sleeve connected to the cut-off valve by means of the
lever m and rod k (see Fig 6)
At Fig 9 n is a curved tube opening at one end into the inner hole or delivery
passage of the cylinder a and at its other end into an entrance opening k¹ in
the upper part of the sleeve c the tube n being filled with hardened steel
balls o o
The action of the apparatus is as follows -At each stroke of the engine one of
the balls oo is forced into the position shown at Fig 6 thus locking together the
sleeve and cylinder 6 which are carned round together until the ball comes
opposite the hole d in the inner cylinder a when it at once passes through into the
interior of the cylinder a and so sets free the outer sleeve e which immediately
returns to its normal po ition by the pull of a conveniently manged spring
forcing of a ball o through the hole d causes all the other balls to be moved forward
and along the passage n (see Fig 9) and thus there is always a ball in readiness
over the opening k for the next stroke of the engine
The
The inner cylinder a being connected with the engine governor (by means of the
rod e) its position is varied according to the varying position of the said governor
and so varies the position of the hole d which 1egulates the closing of the valve by
allowing the ball to pass through earlier or later and so to liberate the outer
sleeve c
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
-
1 The improved disengaging mechanism comprising an inner and an outer
horizontally disposed cylinder the one rotatable within or outside of the other the
said cylinders operating in combination with a perforated lever or levers and a ball
capable of passing through holes in the lever or levels and the cylinders along with
attendant mechanism for rotating one of the said cylinders either in one direction
or the other as required substantially as hereinabove described and shewn in the
drawings
2 The combination with disengaging mechanism of the kind referred to in
Claim 1 of teetotum mechanism arranged and operating substantially as described
and shewn in the drawings for the purpose specified
