page_text: I, ADAM CARLISLE BAMLETT, of Thirsk, in the County of York, Agricultural
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to double action haymaking machines, in which the rotary
forks for spreading and afterwards turning the hay are mounted on a sleeve upon
the axle of the carrying wheels and are driven by sun and planet gearing.
In such machines the gearing has been driven in its forward action for spreading
the grass and in its backward action for turning it by a reversible pawl engaging
with ratchet wheels fixed respectively on the main axle and to the carrying
wheels.
According to this invention I mount on the axle three tubes one outside the
other. The carrying wheel is fixed to the middle tube. The outer tube has an
enlargement at its inner end in which there is an internal ring of teeth gearing with
the planet wheels, which also gear with a ring of teeth on the sleeve carrying the
forks. Means are provided for fixing this tube either to the frame of the machine
or to the middle tube and carrying wheel. The inner tube has at its inner end a
disc or arms carrying studs on which the planet wheels are mounted. Means are
provided for fixing this tube either to the axle or to the middle tube.
For the forward motion the outer tube is fixed to the middle tube by a pawl
pivotted to it which drops into notches on the middle tube and for the back notion
it is fixed to the frame by a radial rod pushed into a hole through it onto the tail
end of the pawl lifting the pawl out of gear so that the act of connecting the outer
tube to the frame disconnects it from the middle tube.
The inner tube is for the forward motion connected to the axle,and for the back
motion to the middle tube by two pawls pointing in different directions on a
common axis pivotted to the tube and put into gear with teeth on the middle tube
or axle respectively by means of a rocking strap carrying lugs and springs which
bear against the pawls pressing one into gear and holding the other out of gear
or if the strap be put in its central position both pawls are held out of gear.
In order to facilitate the oiling of the gearing, the rotating forks are arranged to
slide on their axle towards the centre of the haymaker so that the gearing is then
exposed for cleansing or oiling and they are held in working position by pawls
pivotted on the main axle. The carrying wheel boss is provided with oil holes to
correspond with the teeth of its inner ratchet wheel, and channels convey waste oil
to the planet pinions.
I mount a supplementary prong on the end of the rotary forks nearer to the
travelling wheels than can be used with the forward or spreading motion, this
increases the working width of the machine when used in its backward or turning
motion, these supplementary teeth are so mounted that they can be folled out of
action when the machine is used in its forward or spreading motion.
The rotary forks are pivotted in the usual manner but kept in working position
by a bell crank carrying a roller pressed by a spring against the inner face of a
cam on the rotary fork this allows the forks to yield on striking an obstruction and
to resume their working position when the obstruction is passed.

page_text: I, ADAM CARLISLE BAMLETT, of Thirsk, in the County of York, Agricultural
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 double action hy making machines, in which the rotary
forks for spreading and afterwards turning the hay are mounted on a sleeve upon
the axle of the carrying wheels and are driven by sun and planet gearing.
In such machines the gearing has been driven in its forward action for spreading
the grass and in its backward action for turning it by a reversible pawl engaging
with ratchet wheels fixed respectively on the main axle and to the carrying
wheels.
Figure 1 is a plan, Figure 2 a side elevation and Figure 3 a part sectional plan
to a larger scale of a machine constructed according to this invention. I mount on
the axle A three tubes a, b and c Figure 3 one outside the other. The carrying
wheel d, which is shown to a larger scale in right hand and left hand side elevation
at Figures 4 and 5, is fixed to the middle tube b. The outer tube a Figures 3, 6
and 7 has an enlargement a' at its inuer end in which there is an internal ring of
teeth a gearing with the planet wheels e, Figures 3, 7, 8 and 9, which also gear
with a ring of teeth B' on the sleeve B carrying the forks f. Means are provided
for fixing this tube a either to the frame of the machine or to the middle tube band
carrying wheel d. The inner tube c Figures 3 and 8 has at its inner end a disc c
or arms carrying studs 3 on which the planet wheels e are mounted. Means are
provided for fixing this tube c either to the axle or to the middle tube b.
For the forward motion the outer tube a is fixed to the middle tube b by a pawl a³
Figures 3, 6 and 10 to 13 pivotted to it which drops into notches 2 on the middle
tube band for the back motion it is fixed to the frame by a radial rod g pushed
into a hole through it onto the tail end at of the pawl a lifting the pawl out of
gear so that the act of connecting the outer tube a to the frame disconnects it from
the middle tube b.
The inner tube c is for the forward motion connected to the axle and for the
back motion to the middle tube by two pawls c and c Figures 3, 5 and 14 to 17
pointing in different directions on a common axis e pivotted to the tube c and put
into gear with teeth 63 on the middle tube or teeth A' Figures 3 & 24 (of which
Figure 23 is an end view) fixed to the axle A respectively by means of a rocking
strap carrying springs which bear against a lug c Figures 14 and 17 on the
pawls pressing one into gear and holding the other out of gear or if the strap be
put in its central position as shown in Figures 5 and 14 both pawls are held out of
gear. The strap and pawls are pivotted respectively at j to a sleeve i fixed to
the inner tube c by a set screw in the hole Figures 14, 15, 18 and 19. The
strap has three notches in it which can be sprung onto a blade fixed to the
sleeve j.
In order to facilitate the oiling of the gearing the rotating forks fand sleeves B
are arranged to slide on the axle towards the centre of the haymaker so that the
gearing is then exposed for cleansing or oiling as shown in Figure 1 and to a
larger scale in Figures 20, 21 and 22. They are held in working position by pawls k
pivotted to a boss k¹ pinned on the main axle. The tube a is provided with oil
holes a to correspond with holes 6' in the tube b one for each of the teeth of its
ratchet wheel and channels es shown in Figures 8 and 9 convey waste oil to the
planet pinions e.

page_text: I mount a supplementary prong f¹ Figures 1 and 26 to 28 of the rotary forks f
nearer to the travelling wheels d than can be used with the forward or spreading
motion, this increases the working width of the machine when used in its backward.
or turning motion, these supplementary teeth are so mounted that they can be
folded out of action as shown in Figure 27 when the machine is used in its forward
or spreading motion. For this purpose they are provided with spring arms or
pawls f working on quadrants f Figures 29 and 30.
The rotary forks are pivotted in the usual manner but kept in working position.
by a bell crank m Figures 27 and 31 to 34 carrying a roller m³ pressed by a
spring m² against the inner face of a cam on the rotary fork f this allows the
forks to yield on striking an obstruction as shown in Figure 31 and to resume their
working position when the obstruction is passed.
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 :-
1. The combination of the three tubes a b and c substantially as described.
2. The means substantially as described for connecting the tubes together or to.
the axle.
3. The combined gearing for haymaking machines substantially as described and
shown in the drawings.
4. Mounting the forks on tubes free to slide on the axle to expose the gearing.
substantially as described.
5. The method substantially as described and shown in Figures 20 to 22 for
holding the forks in position on the axle.
6. The supplementary prong substantially as described.
7. The arrangements for oiling the machine substantially as described.
8. The means substantially as described for allowing the forks to yield to an.
obstruction.
9. Haymaking machines substantially as described and shown in the drawings.
