PROVISIONAL SPECIFICATION.
Improvements in Horse-rakes.
J, PHILIP JOSEPH PARMITER, of the Harrow Works, Ansty, near Salisbury,
in the County of Wilts, Agricultural Implement Maker, do hereby declare the
nature of this invention to be as follows:-
My invention relates to horse-rakes and comprises an improved arrangement of
mechanism for lifting and locking the teeth or tines whereby the load on
the same can be easily regulated and the rake will work with safety over the
roughest ground.
In carrying out my invention I provide upon the main axle of the rake a lever
to which is jointed the rear end of a platform or treadle to the front of which is
attached a chain passing rearwards and connected to the seat-stay so that when the
driver presses his foot upon the front end of the treadle the rake will be prevented
from lifting but when the pressure is transferred to the rear end of the treadle the
rake will be lifted.
1 mount the driver's seat in such a manner that it can rock in order to follow the
movement of the driver when working the treadle.
The ends of the main axle are cranked where they enter the travelling wheels so
that the driver's weight upon the seat will depress the axle and thereby keep the
teeth of the rake, which are fixed directly to the axle, down to their work. When
however he throws his weight onto the treadle the cranks will cause the axle to
slightly rise and the rake teeth will be lifted a corresponding distance.
The clearing rods are each made in two parts connected together by a joint so
arranged that one part can be placed and fixed in any required position relatively
to the other part which extends from the rake-frame for a suitable distance between
the teeth. By this means the movable parts of the rods can be adjusted so as to
clear the rake teeth at any desired height.
I construct the rake teeth with two spring bows or loops near the end which is
fixed in the axle for the purpose of giving a spring to the teeth and of carrying
them to a certain height above the axle in order that they shall have a good sweep
and spring to enable them to carry a load.
Through one of the loops of the rake teeth I pass a rod which is loosely attached
to the two end teeth so that when any tooth is strained beyond the remainder the
rod will bear against them and assist the spring.

COMPLETE SPECIFICATION.
Improvements in Horse-rakes.
I, PHILIP JOSEPH PARMITER, of the Harrow Works, Ansty, near Salisbury, in
the County of Wilts, Agricultural Implement Maker, 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 relates to horse-rakes and comprises an improved arrangement of
mechanism for lifting and locking the teeth or tines whereby the load on
the same can be easily regulated and the rake will work with safety over the
5 roughest ground.

page_text: In carrying out my invention I provide upon the main axle of the rake a lever
to which is jointed the rear end of a platform or trendle to the front of which is
attached a chain passing rearwards and connected to the seat-stay so that when the
driver presses his foot upon the front end of the treadle the rake will be prevented
from lifting but when the pressure is transferred to the rear end of the treadle the
rake will be lifted.
The ends of the main axle are cranked where they enter the travelling wheels so
that the driver's weight upon the sent will depress the axle and thereby keep the
teeth of the ruke, which are fixed directly to the axle, down to their work.
The clearing rods are each made in two parts connected together by a joint so
arranged that one part can be placed and fixed in any required position relatively
to the other part which extends from the rake-frame for a suitable distance between
the teeth. By this means the movable parts of the rods can be adjusted so as to
clear the rake teeth at any desired height.
I provide the rake teeth with a spring bow or loop near the end which is fixed to
the axle, the spring bows and teeth being so arranged as to give a spring to the
teeth without allowing them to vibrate and to permit them to yield when
encountering an obstacle or irregularity of the ground.
To enable my invention to be fully understood I will describe how it can be
carried into practice by reference to the accompanying drawings, in which
Figure 1 is a plan of a horse-rake embodying my improvements, and
Figure 2 is a vertical section of the same.
Figures 3 and 4 are elevations, and
Figure 5 a plan drawn to an enlarged scale, illustrating the spring bow or loop
with which provide the rake-teeth.
a is the lever which I provide upon the main axle 6 of the rake the said lever
being bent or cranked backwards as shown clearly in Figure 2.
e is the platform or treadle jointed at its rear end to indienting the joint) to the
lever a, the said end being adapted to lie upon the backwardly bent portion of the
lever a when the rake-teeth are lowered. is the chain attached to the front
part of the platform or treadlee and to the seat stay
r
By this means it will be evident that, the parts being in the position shown by
the full lines in Figure 2. if the driver presses his foot upon the front end of the
treadle the latter, being supported by the chaine at a point behind that to which
the pressure is applied, will have a tendency to lift the lever a which however it
cannot do by reason of the contact of its back end with the rearwardly bent part
of the lever, thereby effectually locking the teeth a' in their lowered or working
position. But, if the driver transfers the pressure of his foot to the rear end of the
trendle e, the trendle and lever will move on their joint of into the position indicated
by the dotted lines in Figure 2 and thereby lift the rake-teeth a'.

wheels h, h so that the driver's weight upon the sent will depress the axle ↳ and
keep the teeth down to their work.
and are the two parts of the clearing rods and is the joint whereby they are
connected; the parts are mounted upon the usual bar m which is adjustably fixed
at n to the seat-stay and the joints are formed by screws which will allow of
their being fixed in any position to which they may be moved so that the rods can
be adjusted to clear the rake-teeth at any desired height.
The spring bows or loops with which I provide the rake teeth, and which will be
most clearly understood by reference to Figures 3, 4 and 5 are made by con-
structing the teeth in two parts, one of which is bent into the form of a clip o
having eyes 7, p and adapted to embrace the axle and to be fixed thereto by
means of a bolt passed through the eyes p, and a nut screwing onto the said
bolt. This part of the rake-tooth is further curved into two coils or loops s and z
having eyes and respectively. The other part of the rake-tooth is at its inner
end bent into the form of a crook to which is placed between the coils s, t and is
passed through the eyes and v and has a certain amount of looseness or play

page_text: therein; it is secured by a lynch pin .e and the other end is suitably curved to form
the tooth or tine proper.
The coils t in this manner securely hold the teeth parallel with one another,
afford a certain amount of spring to the teeth without allowing them to vibrate, and
admit of their moving over the ground with a light or yielding action.
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.) In a horse-rake the combination with the main axle carrying the teeth, of a
lever, fixed to the said axle, a platform or treadle jointed to the said lever and
a chain forming a support for the said treadle for the purpose set forth and
substantially as hereinbefore described and illustrated in Figures 1 and 2 of the
accompanying drawings.
(2.) Constructing the main axles of horse-rakes with cranked ends, the driver's
seat being so arranged relatively thereto that his weight upon the seat will depress
the axle and thereby hold the teeth down to their work substantially as hereinbefore
described with reference to Figures 1 and 2 of the accompanying drawings.
(3.) Constructing the clearing rods of horse-rakes in two parts jointed together
in such a manner that one part can be placed and fixed in any required position
relatively to the other part substantially as and for the purpose set forth.
(4.) Constructing the teeth of horse-rakes with spring bows or loops consisting
of coils in one part of the tooth between which coils the inner end of the other
and separate part of the tooth is held substantially as and for the purpose herein-
before described.
(5.) A. horse-rake having spring teeth constructed in the manner hereinbefore
described and illustrated in the accompanying drawings.
(6.) The improved horse-rake hereinbefore described and illustrated in the
accompanying drawings.
