Improvements in Appliances for Controlling the Rakes of Side
Delivery Reaping Machines.
I ERNEST SAMUELSON of Banbury in the County of Oxon, Engineer, do
hereby declare the nature of this invention to be as follows :-
My invention refers to improved appliances for controlling the rakes of side
delivery reaping machines in order that they may be converted from rakes into
dummies or vice versa, so that the size of the sheaves may be regulated according to
the nature of the crop whether heavy or light, and the action of the rake may be
suspended when the machine is turning round a corner of the field, and all this,
may be effected by the driver from his seat during the progress of the machine.
Upon a prolonged axis fitted to the switch of the rake cam usually employed in
this class of machinery I fit a sliding collar which is retained in its position upon
the switch by means of a feather or other equivalent means; upon this sliding
collar is placed a projection which works against the face of a cam arrangement,
and also 2 lugs which are operated upon by one end of a bell crank lever working on
a fulcrum, to the other end of which is attached a handle with spring bolt which bolt
fits into a notched quadrant on the frame of the machine. The switch is kept open
by a spring coiled round the tail end or axis of same except when a cam acts upon
the projecting lug on the sliding collar. The cam arrangement is operated in one
case direct by the rake shaft and in the other by means of a pair of bevel wheels,
or their equivalent, one of which is fitted to the rake shaft. Upon the hand lever
is fitted a thumb crank and a bell crank, one end of which latter is attached to one
of the lugs on the sliding collar, so that when the driver wishes to alter the
action of the switch, the switch is opened and the sliding collar can be moved
up or down upon the projecting axis of the switch. This bell crank is connected
to the lug and also to the thumb crank by an extensible connection. Upon this
sliding collar I also place a second projecting lug which is attached in any con-
venient manner to a foot lever within reach of the driver so that without altering
the setting of the rakes the driver can close the switch at any moment and cause
any rake to become a dummy.
1 effect this same object in another manner by using in connection with the
sliding collar a second collar held in its proper position on the axis of the switch
by the first collar and connected thereto by means of a spring which presses the
controlling lug against the cam wheel when at work. I connect the hand lever as
before upon the first collar, but the foot lever and connecting arrangement is
attached to the second or controlling collar.

Improvements in Appliances for Controlling the Rakes of Side
Delivery Reaping Machines.
I, ERNEST SAMUELSON of Banbury in the County of Oxon, 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 :-
My invention refers to improved appliances for controlling the rakes of side
delivery reaping machines in order that they may be converted from rakes into

page_text: dummies or vice versa, so that the size of the sheaves may be regulated according
to the nature of the crop whether heavy or light, and the action of the rake may be
suspended when the machine is turning round a corner of the field, and all this may
be effected by the driver from his seat during the progress of the machine, and in
order that my invention may be more clearly understood I add the following
figures showing the apparatus employed.
Figure 1 is a side elevation of the main frame of a side delivery reaper showing
controlling arrangement as attached to the switch upon the cam path round which
the rake arms travel; this figure shows only 3 rake arms, the other one being
removed for the sake of making the drawing more clear. The platform of the
usual quadrant shape is shown in section only for the same reason.
Figure 2 shows a plan of the cam path enlarged, round which the rakes travel
or are guided; with the controlling gear and controlling cam when used upon a
machine fitted with 4 rakes.
Figure 3 is an enlarged elevation showing part of the controlling arrangement
with cam and controlling switch only on the rake shaft.
Figure 3 showing another view of the sliding collar on the prolonged axis of
the switch.
Figure 4 shows part of the controlling arrangement fitted to the rake shaft only
when in use for 5 rakes.
Figure 5 shows the side elevation of half the cam wheel as used in Figure 4.
Figures 6 & 7 show another plan for controlling the switch.
Figures 8 & 9 show an alternative plan when 5 rakes are used.
The same letters refer to the same parts in the different figures.
In Figure 1-A is the main frame of the machine, whilst B shows the main road
or travelling wheel. C is the cam path round which the rollers R, R, which are
fitted on to the end of the rake arms S, S, travel; being pivotted on the pins P, P,
to the rake head H in the usual manner. C is the upper cam path on which
these rollers travel when the rakes act as dummies.
The rake head H is keyed on to the rake shaft S¹ which passes through the
centre boss of the cam C in the usual method-this cam path being fastened to
the main frame of the machine by any of the usual methods employed in this
class of machinery. Upon the other end of the rake shaft S' is keyed a bevel
wheel W which is driven by means of a bevel pinion V which is in connection
with a train of gearing of any suitable form and driven by the main travelling
wheel B. Upon the shaft S', I also fix another cam C₁ having a double
path a, a'. D is the controlling switch which radiates upon a prolonged axis E
which axis E rotates in a boss formed upon the under side of the cam C. A coiled
spring F is placed round the boss of the cam C above mentioned, being fixed to
the cam at one end, and to a pin in the axis E at the other end in any convenient
manner. Upon the lower end of the axis or spindle E which may be either
square as shown in the drawing (Figs. 2, 3, & 4) or round with a feather fitted into it
(as in Figs. 6, 7, 8, & 9) slides a loose bracket G; to this bracket projecting
portions L, L, are fixed between which a small friction roller revolves, see
Figures 2, 3, 3, 4, 6, & 7 etc. Another small projection L' is placed underneath
the two projecting levers L between which one end of the bell crank lever M is
loosely fitted, see Figures 2, 3, 3^, 4, 6, 7, & 8. This bell crank lever is pivotted
upon a pin N suitably fixed to the main frame of the machine. To the other end
of this bell crank is fastened a long lever O which is brought conveniently within
the reach of the driver upon his seat. A spring bolt Q is attached to the lever
and fits into notches upon a quadrant T fixed to the main frame of the machine.
This spring bolt Q is moved in and out of the quadrant notches by means of a
thumb crank U and connecting wire or chain X attached to a loop Z fixed to one
side of the spring bolt. Upon a stud S2 fastened to the bell crank M is another
small bell crank b; at one end of this bell crank is a loop and this end is
attached to the loop Z of the spring bolt by means of a wire or chain X. The
other end of the bell crank is attached by means of a wire X³ to the projecting

page_text: lug L' on the sliding socket G. Upon the sliding collar GI also place another
projecting lug L which is attached by means of a wire X or other equivalent
connection to a foot lever within reach of the driver in any of the usual methods.
a
The cam C with its two paths a, a', is of such a shape that during certain
portions of its revolution it acts upon the small roller rand by means of the collar G
closes the switch D as shown in full lines in Figure 2, and allows the rake to be raised,
and so sweep over the platform when raking off the cut crop by travelling over the
upper cam path C. Upon a 4 rake machine the 2 paths a, a', on the cain C' are
segments of a circle which pressing upon the roller r close the switch D during
certain portion only of the revolution of the rake head. During the remaining
portion of the revolution the coiled spring Facts upon the prolonged axis of the
switch D and opens it to the position shown in dotted lines in Figure 2, and allows
the rake to pass round the lower cam path of C and sweep the cut crop off the
platform. By means of the extensible connections between the thumb crank U,
spring bolt Q, and bell crank lever b, the collar G with its lugs L, L, L¹, & L³, is
free to rotate with the axis E without altering the position of the spring bolt Q in
the notch in the quadrant in which it has been placed by the driver. Thus in
the case of a 4 rake machine if the attendant wishes to allow one rake to sweep the
platform, and the remaining 3 to act as what is known as dummies, the roller
is placed by means of the hand lever in such a position that it is acted upon
by the lower cam path a' of the cam C' which retains the switch closed as shown
in Figure 2 for about of a revolution of the rake shaft S. Upon the release
of the pressure of the cam a' upon the roller r the spring F opens the switch D
as shown in dotted lines in Figure 2, and allows the fourth rake to pass round
the lower path of the cam C and to rake the cut crop from off the platform.
If the driver wishes to rake the crop off with every alternate rake, he moves the
sliding collar G up the axis E by means of the lever O on to the cam path a, b,
which open the switch twice in a revolution of the rake shaft. The roller is
kept in its proper relative position upon the spindle E by means of the spring
bolt Q fitting into one or other of the notches on the quadrant T. If when the
collar G is set to act upon every second or third rake, as the case may be, the
driver wishes to control the switch D and allow the rake roller R to pass ou to
the upper cam path C of C and leave the crop on the platform, he uses a foot
lever, or other convenient means, not shown, which is connected with the lug L'
by means of a cord ✗* and closes the switch D. In order that the driver may
rake off the cut crop from the platform with every rake, to make a swathe, he slides
the collar G with its projecting lugs L, L, and friction roller r out of contact with
the cam Centirely. The spring F then acts upon the switch D and retains it in
its open position as shown in dotted lines Fig. 2; the controlling foot lever how-
ever can be put into operation by the driver from his seat and the switch D closed
by means of the lug L² and cord at any time when required so that the rake
travels over the upper cam path C.
Figures 4 & 5 show the arrangement used for acting upon the friction roller r
on the sliding collar G when 5 rakes are employed. The cam wheel Y upon which
are the cam paths Z1, Z2, Z3, shown in Figure 5 is rotated on the stud Y' fixed to
the main fraine of the machine and rotated by means of a bevel wheel Y' and
bevel pinion Y³ fitted to the rake shaft S¹ of the machine.
Figures 6 & 7 show an alternative method of controlling when 5 rakes ar
employed. In this case a pinion Se is fitted on to the rake shaft S' and gears with
an internal spur wheel S³ upon which are a series of cams S, S',-these cams vary
in number according to the number of "rakes" required, and are placed in series
one set above another upon the spur wheel S³ as shewn. This spur wheel S³ rotates
upon a pin S fixed in any convenient method to the main frame of the machine.
Any other convenient method of gearing may be used in conjunction with the
sliding collar G and the levers O, b, and M.
Figures 8 & 9 illustrate another method of controlling the switch D. I use a
pinion S as before, fitted on to the rake shaft S', and gearing into an external

page_text: spur wheel S³ which has a series of cams 'S', S, placed one over the other as in the
previous case, but I'make the sliding collar G in two parts G, G, the portion G¹
being held in its proper relative position on the prolonged axis E of the switch D
by the main collar G as shown in Fig. 8, at the same time it is'arranged to revolve
round the axis E. within a limited space. This collar G has projecting lugs H2,
and H³, and upon G is a projecting lug H. To H' is bolted a spring F the
other end of which presses against the lug H2. H2 also comes in contact with
the side of G which forms a stop or limit to the movement of G. The lever M
works in the collar G between the two lugs L, L, and enables the attendant to
slide the collar G and with it the supplementary collar G up and down the
prolonged axis E and so bring the lug H³ into contact with the cams S₁, S', of
either of the three grades on the cam wheel S³ as required; the foot lever and
connecting cord X however is attached to the collar Gas before. This enables
the attendant to close the switch D at any moment without reference to the relative
position of the lug H³ and the series of cams St.
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 :-
1st. The combination of the appliances for controlling the rakes of side delivery
reapers as shown and described.
2nd. The combination of a hand lever with spring bolt and quadrant, together
with the bell crank levers M & b, with extensible connections X and which may
be either wires working in compensating slot holes on the ends of the lever and
spring bolt as shown, or flexible chains, or their equivalents, with a controlling
arrangement for operating the switch on the rake arm cam, or patli, of a side
delivery reaper as shewn and described.
3rd. The combination of a controlling cam placed on the rake shaft, or upon
a pin fixed to the frame of the machine, and driven by suitable gearing from
the rake shaft, with a sliding collar on the projecting axis of the switch, and a
spring acting upon same to keep the switch open when the lever or lug on the
sliding collar is not being acted upon by any of the cam paths, as shewn and
described.
