IMPROVEMENTS
The first part of my Invention refers to the mode or means provided for
connecting the teeth or tines to horse rakes. pass the main axle through a
hollow shaft or sleeve, preferably in parts, to which latter the teeth or tines are hung
from grooved projections or brackets, or in other words I attach the teeth or tines
to horse rakes by passing the main axle through the teeth or teeth holders, and
thereby I am able to dispense with a separate tooth bar or hinge, at the same time
allowing the teeth to work independently of each other; the tooth is placed in the
groove and secured by a suitable pin upon which it is free to work independently
within the limits of the groove; in order that the sleeve may remain rigid on the
axle when the teeth are being raised, I form them to fit a square axle; by
preference the teeth may themselves work loose upon the axle, and for this purpose
a suitable rod or its equivalent is placed beneath the teeth to support them when
being raised.
The second part of my Invention refers to the arrangement for rendering the
rake self-acting; for this purpose I mount the wheels loose upon the main axle to
each end of which I rigidly attach a vertical arm provided at their upper ends
with pins, which project over the outer rim or tyre of the travelling wheels, and to
each pin is hinged a brake; depending from the brakes are vertical rods which are
again connected to a horizontal bar passing along the front of the rake and under
the foot of the driver; when the latter wishes to dischargo the load he presses his
foot lightly upon the horizontal bar, which immediately brings the two brakes on
to the travelling wheels, causing the main axle to revolve and lift the teeth; as soon

to keep the horizontal bar in position a strap may be placed round the axle and
connected to the horizontal bar.
The brakes may be worked by a lever.
The third part of my Invention refers to the construction of the shafts of horse
rakes of tubes which are bent at the ends and dropped over pins, which latter work
loosely upon the main axle. Into the boss or nave of the wheel I screw tubular
spokes which are flattened at their upper ends and rivetted to the tyre.
Horse rakes constructed according to my Invention are with facility taken to
pieces for packing and other purposes, and speedily put together again.

IN HORSE RAKES,"

IMPROVEMENTS
The first part of my Invention refers to the mode or means provided for
connecting the teeth or tines to horse rakes.
Figure 1 of the accompanying Drawing is a side elevation; Figure 2 is a plan of
a portion; and Figure 3 is an elevation of one side of a horse rake constructed
according to my Invention; Figures 4 and 5 are views of parts in detail. Similar
letters of reference refer to like parts in all the Figures; a is the main axle which
is passed through a hollow shaft or sleeve made in parts or teeth holders b, each
having one or two teeth or tines, thus dispensing with a separate tooth bar or hinge
while at the same time allowing the teeth to work independently of each other;
the main axle a is round and has a feather as shown in section Figure 4, which
also shews a broader keyway in the sleeves b, thus allowing a certain amount of
play in order that the tines inay rise slightly if meeting with a stone or other
obstruction; this play is more especially necessary where the tines are fixed to the
sleeves b, as shown in that Figure, or the axle a may be of square section and the
sleeves b made with a loose fit for the same purpose, as shown in Fig. 6. In
Figs. 1, 2, and 5, the sleeves b are made to fit the shaft a, and I hang the tines
or teeth in grooved brackets formed on the sleeves, and I connect them thereto by
joint pins, but so that the teeth can only turn to a limited extent on their joint
pins as required to clear obstructions.
To render the rake self acting I mount the wheels c loose upon the main axle a,
to each end of which 1 fix an upright arm d; these arms are at the upper end each
provided with a pin e projecting over the rim or tyre of the travelling wheel c, and
to each pin e is hinged a brake from which depends a rod g jointed thereto, and
at its lower end connected to a lever j loose on the axle a and carrying a horizontal
bar h passing along the front of the rake and under the foot of the driver. When
the latter wishes to discharge the load he presses his foot lightly on the bar h,
which immediately brings the two brakes fon to the wheels c, causing the main
axle a to revolve and lift the teeth; as soon as he releases the bar h the teeth fall
back into their position for raking; k is a helical spring attached to lever ; and
rod g assisting in bringing the bar h into its normal position when the foot pressure
is taken off it. The rakes may if desired be worked by a hand lever.
The third part of my Invention refers to the construction of the shafts of horse
rakes; 1, 1, are the shafts made tubular and bent at one end, as shown in Figure 5,
and dropped over pins m which are each on a ring working loosely on the main
axle a
Into the boss or nave of the wheels c I scrow tubular spokes c', which at their
outer ends are flattened and rivetted to the tyre, as shown at Figure 5.
Horse rakes constructed according to my Invention, that is, with the removable
shafts, are readily taken to pieces for packing and other purposes, and speedily put
together again; the shafts when taken off are laid across on the machine, and
thus take up no extra space.
And having thus described the nature of this Invention, I declare that I
claim,―
Firstly. The combination of parts for dispensing with a separate tooth bar, at the
same time allowing the teeth to work independently of each other, substantially as
described and as shown on the accompanying Drawings.
Secondly. The combination of parts forming a brake on the wheel tyres for

accompanying Drawings.
Thirdly. The combination of tubular shafts and pins loosely connected to the
main axle, substantially as described and as shown in the accompanying Drawings.
In witness whereof, I, the said Edwin Henry Tooley, have hereunto set my
hand and seal, this Twenty-first day of October, in the year of our Lord One
thousand eight hundred and seventy nine.
EDWIN HENRY TOOLEY. (L.S.)
