IMPROVEMENTS IN HORSE RAKES
Year: 1884

page_text: "
I, ADAM CARLISLE BAMLETT of Thirsk in the County of York Engineer do
hereby declare the nature of my invention for "IMPROVEMENTS IN HORSE RAKES
to be as follows:-
In order to secure the greatest amount of raking width in a rake constructed to
pass through gateways of limited width, I form the bosses of the road wheels
within the outer face of the wheel, and to give steadiness, increase their length on
the inner side and extend the part of the rocking frame to which the teeth are
pivoted outwards or beyond the ends of the bosses of the road wheels by cranking
the ends of the frame, and in order to improve and simplify the construction of
the backing and lifting mechanism I mount upon the main axle what I will call a
double armed lever, one arm springing up above the frame has a spring mounted
upon it. This arm of the double armed lever is connected to the lifting lever by
a forked connecting rod and has a bent horn which passes through the fork of the
connecting rod (the solid end forming the stop). When the rake is lifted to
discharge the load, part of the said horn forms a guide for the already mentioned
spring, and is provided with a sliding washer which is held up by the spring
having projections to act upon the underside of the forked connecting rod for the
purpose of raising it over the dead centre and thus locking it. The second arm of
the double arın lever is bolted to one of the bars of the main frame and is
provided with a slot or a series of holes for the purpose of adjusting the pitch of
the teeth, or made to work in a guide and operated on by a screw.
A stop is
provided to prevent the lifting lever raising the rake teeth above the necessary limit
for discharging the load. The foot lever I make double ended so that the driver
can use either his right or left foot for discharging the load.

I, ADAM CARLISLE BAMLETT of Thirsk in the County of York Engineer do
hereby declare the nature of my invention for "IMPROVEMENTS IN HORSE RAKES
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:—
This Invention has for its object improvements in horse rakes.
In order to secure the greatest amount of raking width in a rake constructed to
pass through gateways of limited width, I form the bosses of the road wheels
within the outer face of the wheel and to give steadiness increase their length on
the inner side; and I. extend the part of the rocking frame to which the teeth are
pivotted outwards or beyond the ends of the bosses of the road wheels by cranking
the ends of the frame.
In order to improve and simplify the construction of the locking and lifting
mechanism I mount upon the main axle what I will call a double armed lever, one
arm projecting upwards above the rocking frame, on which the rack teeth are
mounted carries a spring. This arm is connected to the lifting lever by a forked
connecting rod, and has a bent horn, which passes through the fork of the
connecting rod.
The horn supports the upper end of the spring and a sliding washer which is
held up by the spring against the under side of the connecting rod for the purpose
of raising it over the dead centre and thus locking it. The second arin of the
double arm lever is bolted to one of the bars of the main frame and is provided
with a slot or a series of holes for the purpose of adjusting the pitch of the teeth
or it may be made to work in a guide and operated on by a screw. A stop is
provided to prevent the lifting lever raising the rake teeth above the necessary
limit for discharging the load. The foot lever I make double ended so that the
driver can use either his right or loft foot for discharging the load.
In order that my said invention may be most fully understood and readily
carried into effect I will proceed to describe the drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a side elevation and Figure 2 is a plan of portions of a horse rake

page_text: and receives a bolt which clamps it adjustably to one of the arms of the frame C.
Other means may be employed for connecting the lever E to the main frame as
already stated.
E is the horn of the lever E, it supports the upper end of the spring F and also
the sliding washer F'. The lower end of the spring F also has an abutment on the
lever E as is seen in Figure 4. G is the lifting lever, it has its fulcrum at G¹ G¹
and the forked connecting rod H H connects it with the lever E at E¹. When the
rake teeth are down in their working position as in Figure 1 the two sides of the
connecting rod H rest upon the washer F' or on projections upon this washer and
so the solid end of the connecting rod at H' is kept up to the under side of the
lifting lever G. The part H¹ thus forms a stop keeping the connecting rod and
lifting lever aligned so that they resist thrust without bending at the point by
which they are connected. L is the foot lever and M and M' are its double ends
which serve to receive the feet of the driver so that either foot may be used to
force down the lever L.
The lifting lever G to which the foot lever is fixed moves with the foot lever
when this is forced down and so raises the tines. A pawl O retains the mechanism
until released by the driver; it engages with a pin on the forward end of the
lifting lever G which serves as a handle. To lower the tines the driver throws out
the pawl and thrusts from him the handle end of the lifting lever and as the tines
descend the spring F carries the connecting rod to the locked position as
represented in Figure 1.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
(1). The combination in a horse rake of road wheels with. inwardly projecting
bosses and a rake frame so formed as to overlap the said bosses.
(2). The arrangement for lifting lowering and locking the rake teeth consisting
of the lever E spring F lifting lever G and connecting rod H the said spring F
serving to lock the parts by supporting the connecting rod in a position such that
the joint between the connecting and the lifting lever is unable to yield.
(3). My improved horserake substantially as described and represented in the
annexed drawings.
