Bedford, for an Invention of "IMPROVEMENTS IN HORSE RAKES."
PROVISIONAL SPECIFICATION left by the said Edwin Henry Tooley at the
Office of the Commissioners of Patents on the 2nd March 1880.

IN HORSE RAKES."
"IMPROVEMENTS
This Invention has for its object improvements in horse rakes, and consists in an
improved arrangement of mechanism for effecting the raising of the tines for the
discharge of the crop by the rotation of the main wheels, such my improvements
being applicable to horse rakes of very different general construction; for instance,
to those in which the tines are mounted in a rocking frame, the same being either
concentric or excentric to the axles of the main wheels, also when the axles are
adjustable on the frames, and to horse rakes in which the tines are not mounted on
rocking frames, but otherwise, as, for instance, when the tines are centred upon the
main axle.
For this purpose I fit upon the nave of one or both of the wheels (or upon the
axle, as the case requires) a bar having an oblong hole to fit and slide upon the nave
(or axle) and allow an inch or two of motion, more or less; one end of the bar
extends a little beyond the rim of the wheel, and is there bent at right angles, so
that when the bar is caused to slide upon the nave the bent over extremity will
come in contact with the rim of the wheel and act as a brake, causing the bar to be
carried round by the wheel.
Thus far my new arrangement will apply generally to all horse rakes mounted
on wheels, but the further mechanism for transmitting the motion of the said bars
(which I shall henceforth call the "brake bars") to the teeth of the rake will
require modification according to the general construction of the horse rake to
which my improvements are to be applied. I will therefore continue the description,
first, of the adaption to horse rakes in which the tines are mounted on a rocking
frame.
In these cases I fix (at each side of the implement) a stud in the forward end of
the rocking frame, and mount thereon a short lever, one end of which is pin-jointed
to a prolongation of the brake bar, and the other end of the lever is coupled with

page_text: the corresponding lever at the other side by a bar passing right across the
implement, this cross bar affording the means of actuating both the short levers
and the brake bars simultaneously from the driver's seat at the centre, and which
may be effected by the customary hand lever, treadle, and locking device. The
short levers form the connection between the brake bars and the rocking frame, so
that when the brake bars are caused to revolve with the wheels they convey the
motion to the rocking frame. The revolution of the brake bars with the wheels, or
the rise of the teeth by the revolution of the rocking frame, is limited by stops
attached to the main frame.
In borse rakes without rocking frames, such, for instance, as those in which the
tines are centered upon the main axle, the brake bars are fitted to the road wheels,
as already described, and the lifting of the teeth is effected by a rod attached to
both brake bars at a point between the axle and the bent extremity, and passing
across the implement just below the teeth and just above the clearing frame. The
brake bars are actuated from the driver's seat at the centre by means of a cross
shaft mounted in the forward ends of the brake bars, and having a crank arm at
each end, and a link connection between the crank arm and the axle. The cross
shaft has the usual hand lever or treadle at the centre, by means of which a thrust
against the axle is exerted through the links aforesaid, causing the brake bars
with their attachments to slide bodily on the naves or axle until the brake pieces
come in contact with the rims of the wheels, and the lifting of the teeth is
effected.

"IMPROVEMENTS
This Invention has for its object improvements in horse rakes, and consists in an
improved arrangement of mechanism for effecting the raising of the tines for the
discharge of the crop by the rotation of the main wheels, such my improvements
being applicable to horse rakes of very different general construction; for instance,
to those in which the tines are mounted in a rocking frame, the same being either
concentric or eccentric to the axles of the main wheels, also when the axles are
adjustable on the frames, and to horse rakes in which the tines are not mounted on
rocking frames, but otherwise, as for instance, when the tines are centred upon the
main axle.
For this purpose I fit upon the nave of one or both of the wheels (or upon the
axle, as the case requires) a bar having an oblong hole to fit and slide upon the knave
(or axle) and allow an inch or two of motion more or less; one end of the bar
extends a little beyond the rim of the wheel, and is there bent at right angles, so
that when the bar is caused to slide upon the nave the bent over extremity will
come in contact with the rim of the wheel and act as a brake, causing the bar to be
carried round by the wheel.

Thus far my new arrangement will apply generally to all horse rakes mounted
on wheels, but the further mechanism for transmitting the motion of the said bars
(which I shall henceforth call the brake bars") to the teeth of the rake will
require modification according to the general construction of the horse rake to
which my improvements are to be applied.
The Drawings hereunto annexed show various constructions of horse rakes with
my improvements applied to them.
Figure 1 is a plan, and Figure 2 a side elevation of so much of a horse rake
with the teeth mounted in a rocking frame eccentric to the axles of the main
wheels as will serve to illustrate the application of my Invention to rakes of this
character.
a is one of the rake bars mounted on the axle; b is one side of the rocking frame;
c, a stud at the forward end of the same, and upon which the lever & turns; e is a
bar passing across the implement to the corresponding lever at the other side, and
which is placed conveniently for the foot of the driver. When the bar e is
depressed the brake bar a slides upon the axle until the bent end f comes in.
contact with the wheel tire; the brake bars are thereby caused to revolve with the
wheels, and the levers d convey the motion to the rocking frame b, and so lift
the tines.
Figure 3 is a plan, and Figure 4 a side elevation of a horse rake with the teeth
centred upon the axle and my improvements applied thereto. a is one of the brake
bars mounted upon the axle; b is the cross shaft mounted in the forward ends of
the two brake bars; c is a lever arm; and d, a link connecting the same with..
the axle; e is the treadle lever; f_is_a_rod-attached to the two brake bars,
and-passing across the implement beneath the teeth and above the clearing
frame g.
When the driver, by pressing with his foot upon the lever e, causes the brake bar
to lay hold of the periphery of the wheel and to revolve with it the rod f lifts the
teeth and effects the discharge of the crop.
Figure 5 is a plan, and Figure 6 a side elevation of a horse rake with a rocking
frame centred upon the main axle, and with my improvements applied thereto in
the best form at present known to me.

page_text: In this arrangement the brake bar instead of being slotted for the axle to pass
through is jointed to a collar which is free to turn around the axle; the effect is the
same, that is, the brake bar can move to and fro radially or approximately so. a is
the brake bar jointed to a short pillar h, which stands out from a collar that can
turn around the axle; the rocking frame b has a stud c at the front end, upon
which is centred the lever d; a bar n passes across the implement and connects the
two levers d; the treadle lever e is conveniently centred on the check bar i carried
by the axle, and a connecting rod m is attached to the bar n near the centre of the
implement.

depressed it acts against the pin of the knuckle joint and depresses it, thereby
unlocking the locking gear o, and setting the frame b free to turn when the brake
bar lays hold of the periphery of the wheel.
The extremity of the brake bar may be formed in various ways to enable it to
lay hold of and grip the wheel when drawn against it.
Figures 5, 7, 8, and 9 shew various ways in which the extremity of the brake
bar a may be formed to effect this object. In Figure 5 the bent extremity of
the bar is simply drawn against the tread of the wheel. In Figure 7 the bent end f
is shaped so as to grip the wheel by the sides of the tire instead of on the tread as
in Figure 5. In Figures 8 and 9 the bent end f of the brake bar carries a loose
piece centred at i, and bent to an angle as g, h. The part g first coming in contact
with the wheel causes the part h to jam the tire of the wheel against the radial
part of the bar a.
Having now described some of the methods at present known to me for carrying
my Invention into practice I would have it understood that what I claim as of my
Invention is,.
First. Effecting the discharge of the crop from horse rakes by the rotation of the
wheels by means of a sliding bar upon the boss of one or both travelling wheels or
upon the axle, and which is moved a short distance radially so that the outward
extremity shall be drawn forward and come in contact with the tire of the wheel,
and thereby be carried round with the wheel as far as required, and by its move-
ment effect the raising of the tines, substantially as described.
Second. The arrangements herein described, or their equivalents, for communi-
cating the partial rotation of the said bar or bars to the rocking frame.
Third. Raising the teeth directly by the partial rotation of the said har or bars
substantially as herein described.
Fourth. The arrangements herein described, or their equivalents, for actuating the
sliding bars.
In witness whereof, I, the said Edwin Henry Tooley, have hereunto set my
hand and seal, this Thirty first day of August, in the year of our Lord On
thousand eight hundred and eighty.
