Year: 1862

page_text: LETTERS PATENT to Thomas Allcock, of Ratcliffe-on-Trent, in the County
of Nottingham, Agricultural Implement Manufacturer and Mechanist,
for the Invention of "IMPROVEMENTS IN THE CONSTRUCTION OF HORSE
RAKES."
Sealed the 2nd December 1862, and dated the 4th June 1862.
PROVISIONAL SPECIFICATION left by the said Thomas Allcock at the
Office of the Commissioners of Patents, with his Petition, on the 4th
June 1862:
I, THOMAS ALLCOCK, of Ratcliffe-on-Trent, in the County of Nottingham,
Agricultural Implement Manufacturer and Mechanist, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN THE CONSTRUCTION OF HORSE
RAKES," to be as follows:-
Heretofore horse rakes have been constructed with a pipe or boss on the
outer sido of the nave of the wheels, in which case the machine is of un-
necessary width; also heretofore the pitch of the teeth has been set by raising
or lowering the wheels in the standards at the end of the machine. Whereas
my improvements consist, first; in placing a boss on the inner side of the
machine at each end thereof, and boring the same nearly throughout its
length, but leaving the inner end closed. In this bored boss I fit a turned.

page_text: axle, and the other end of the axle I insert and secure in the nave of the
wheel. I also cut a groove round the end of the axle that is placed in the
boss, and pass a set screw through the boss, the end of the screw taking into
the groove, thereby securing the axle fast in the boss, but leaving it free to
revolve.
. The pitch of the teeth I alter or vary in the following manner:-In
the machine I place two or more transverse bars, upon each of which I
place a clip, which clip embraces each such said bar. These clips have a
series of holes in them, through which I pass a spring cotter, the cotters
passing through a hole in each transverse bar; the lever bar on which the
teeth of the rake rest lies on the top of the clips, so that the pitch of the teeth
is regulated by the height at which the clips are placed and secured on the
bars. The teeth can thus be set either to touch the ground, or just to clear
it, or they may be raised up to the highest point required. There is attached
to my machine a presser bar, which works on the top side of the teeth, for the
purpose of making the teeth hold closer to their work.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Allcock in the Great Seal Patent Office on the
4th December 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
ALLCOCK, of Ratcliffe-on-Trent, in the County of Nottingham, Agricultural
Implement Manufacturer and Mechanist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourth day of June, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Thomas Allcock, Her special licence, that I, the said Thomas Allcock,
my executors, administrators, and assigns, or such others as I, the said
Thomas Allcock, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time, and at all times thereafter
during the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
THE CONSTRUCTION OF HORSE RAKES," upon the condition (amongst others) that I,
the said Thomas Allcock; my executors or administrators, by an instrument in

page_text: writing under my, or their, or one of their hands and seals, should particularly
describe and ascertain the nature of the said Invention, and in what manner
the same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately after the
date of the said Letters Patent.
NOW KNOW YE,' that I, the said Thomas Allcock, .do hereby declare the
nature of the said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following state-
ment thereof, reference being had to the accompanying Drawings; and to the
letters and figures marked thereon, that is to say:
.
Heretofore horse rakes have been constructed with a pipe or boss on the.
outer side of the nave of the wheels, in which case the machine is of un-
necessary width. Heretofore also the pitch of 'the teeth has been set by .
raising or lowering the wheels in the standards at the end of the machine.
Now my improvements consist, first, in placing a boss on the inner side of the
machine at each end thereof, and boring this boss nearly throughout its length,
but leaving its inner end closed. In this bored boss I fit a turned axle, and
the other end of the axle I insert and secure in the nave of the wheel. I also
cut a groove round that end of the axle which is placed in the boss, and pass
a set screw through the boss, the end of this screw taking into the groove, and
thereby securing the axle fast in the boss, but leaving it (the axle) free to
revolve.
My improvements next consist in the following improved mode of altering
or varying the pitch of the teeth. For this purpose I place two or more
transverse bars in the machine, upon each of which bars I place a clip; these
clips embrace the bars, and have a series of holes in them, through which I
pass spring cotters, the cotters also passing through holes in the transverse
bars, that is to say, each cotter passes through one of the holes in one of the
clips, and through a hole in the transverse bar embraced by such clip; the
lever bar on which the teeth of the rake rest lies on the top of the clips, so
that the pitch of the teeth is regulated by the height at which the clips are
placed and secured on the bars. The teeth can thus be set either to touch
the ground, or just to clear it, or they may be raised up to the highest point
required. There is attached to my machine a presser bar, which works on
the top side of the teeth, for the purpose of making the teeth hold closer to
their work.
Having thus set forth the nature of the said Invention, I now proceed
more particularly to describe the manner of performing the same with
reference to the accompanying Drawings.

page_text: DESCRIPTION OF THE DRAWINGS.
Figure 1; Sheet 1; is a plan of a rake constructed according to my improve-
ments; and Figure 2, Sheet 2, is a side view of the same. with one of the
wheels, and also one end of the frame, taken away to render the Drawing
more clear. . The several.corresponding parts .in. each Figure are lettered
alike. "
P
.
I place a boss A on the inner side of the frame B at each end of the
machine. (There are thus two bosses A (one at each end) ;-I-bore each.boss
nearly throughout its length, but leave its inner end closed. In each boss A
I fit a turned axle (one of which axles is represented by dotted lines at the
left-hand end of Figure 1). I insert and secure the other end of the axle in
the nave C of the wheel, and I cut a groove round that end of the axle which
is placed in the boss, and pass a set screw D, shewn in Figure 2, through the
boss; the end of the screw takes into the groove, and thereby secures the axle
fast in the boss, but, as before stated, leaves it free to revolve.; E are' the
teeth of the rake.
clips, so that the
The pitch of the teeth E, I vary in the following manner :-I place two or
more transverse bars F in the machine, upon each of these bars. I place a
clip G; these clips embrace the bars. Each clip has a series of holes made in
it, through one of which holes in each clip. I pass a cotter H, the cotter also
passing through a hole in the transverse bar embraced by such clip, so that
according to the hole selected in the clip for the cotter to pass through, the
height at which the clip is placed on the bar is regulated. The lever bar I
on which the teeth of the rake rest lies on the top of the
pitch of the teeth is regulated by the height at which the clips are placed and
secured on the bars. By these means the teeth may be, set either to touch
the ground, or just to clear it, or they may be raised up to the highest point
required. K is a presser bar which is attached to my machine, and lies on
the top side of the teeth for the purpose of making the teeth hold closer to
their work. The teeth are raised or lowered by the lever handle L, and the
connections attached to it, and to the bars I, K. There, is, of course, a cotter
H to each clip G, to secure the clip to the, bar the height required, as
described.
'
Having now described the nature of the said Invention, and in what manner
the same may be performed, I declare that I claim as my improvements in the
construction of horse rakes,
First, disposing and arranging the bosses of the wheels as herein-before
described.

page_text: Second, the arrangement and combination of parts herein-before described,
for altering or varying the height of the teeth.
Third, the general arrangement and combination of parts constituting the
improved horse rake, herein-before described.
In witness whereof, I, the said Thomas Allcock, have hereunto set
my hand and seal, this Second day of December, in the year of our
Lord One thousand eight hundred and sixty-two.
