Year: 1874

page_text: LETTERS PATENT to Edward Stacey Spencer, of Benfield, Bury
Stansted, in the County of Essex, for the Invention of "Im-
PROVEMENTS IN HORSE HOES."
Sealed the 4th September 1874, and dated the 27th June 1874.
PROVISIONAL SPECIFICATION left by the said Edward Stacey Spencer
at the Office of the Commissioners of Patents, with his Petition,
on the 27th June 1874.
I, EDWARD STACEY SPENCER, of Benfield, Bury Stansted, in the
County of Essex, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN HORSE HOES," to be as follows:-
This Invention has for its object improvements in horse hoes. For
this purpose the axle of the machine is, as usual, carried by brackets
from the rear end of the shaft; a long axle is employed, upon which the
wheels can revolve freely, and the wheels are held in position by collars
fixed to the axle on either side of it by set screws, and by varying the
position of the collars upon the axle the wheels can be set in any desired
position upon it. The axle may also be shifted endwise in a similar

page_text: manner through its bearings in the brackets; the brackets also carry
hooks, from which are suspended lever arms which have handles con-
nected to them at their rear ends, and have also fixed to them a pair of
horizontal bars, to which the several hoes are connected. The horizontal
bars are suspended by chains which are passed around the ends of a
barrel carried by a frame projecting from the shafts in rear of the axle,
and by winding up the chain upon this barrel the hoes can be raised or
lowered, and so set to cut at any desired depth; the hoes are guided in
the ordinary manner by the man holding the lever handles, and to enable
this man also to raise or lower the hoes without stopping the machine
the barrel at its centre has jointed to it a number of lever arms, by
which he may turn it; each arm is connected by a link or chain to a
slide capable of moving endwise upon the barrel. This slide has collars
upon it, between which is received one end of a rod which passes
through a slot or recess in one of the fixed bearings that carry the barrel.
When the slide is moved away from the lever arms the opposite end of
the rod enters into notches or recesses formed in a wheel which is fast
upon the barrel, and so locks the barrel from turning. Thus whilst the
man steers the hoes with one hand he can with the other hand lay hold
of one of the lever handles, and by turning it on its hinge bring it into
a position at right angles to the barrel; this moves the slide above
mentioned along the shaft, and by so doing withdraws the rod from the
notches or recesses in the wheel and sets the barrel free, so that the man
can turn it in either direction by the lever handle, and when he has thus
either sufficiently raised or lowered the hoes he can again lock the axle
by allowing the lever arms to turn back into their former position and
the slide to shift endwise along the axle; a spring is used to pull or push
the slide into a position to lock the barrel.
The stems of the several hoes are fixed by clips to the two parallel
bars above mentioned, and these bars are also fixed by clips to the lever
handles, so that the bar, together with the hoes carried by it, can be set
either centrally or to project to a greater or less extent to one side or
other of the machine.
The hoes can also be set at any desired distance apart from one
another upon the bars.
Two sets of bars, each carrying hoes, can also be fixed one in front
of the other to the lever handles, so that one set of hoes may be in

page_text: advance of the other. The two parallel bars which carry the hoes are
one above the other, the stem of each hoc is received into a notch in a
block which lies between the parallel bars. Each block has a horizontal
slot formed in it, through which is passed a clip which embraces the
stem of the hoe and draws it tightly against the front edge of the bars,
there being a nut screwed on to a stem at the back of the clip which
bears against the back edge of the bars.
The clips by which the bars are secured to the lever handles are formed
in the following manner :-Each lever has a block secured to it, from the
front of which a pin projects; this pin passes between the two hori-
zontal bars and through a clip piece. A nut is screwed on to the end of
the pin, which presses the clip picce against the bars and holds them
against inclines on the block; the inclines draw the bars inwards
towards the pin, and thus holds the bars securely.
› SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Edward Stacey Spencer in the Great Seal Patent
Office on the 24th December 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
STACEY SPENCER, of Benfield, Bury Stanstead, in the County of Essex,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-seventh day of June, in the year
our Lord One thousand eight hundred and seventy-four, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Edward Stacey Spencer, Her special
license that I, the said Edward Stacey Spencer, my executors, admini-
strators, and assigns, or such others as I, the said Edward Stacey
Spencer, 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 HORSE HOES," upon the condition (amongst others)
that I, the said Edward Stacey Spencer, my executors or administrators,

page_text: by an instrument in 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 Edward Stacey Spencer, 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 statement thereof, that is to say :—
This Invention has for its object improvements in horse hoes. For
this purpose the axle of the machine is, as usual, carried by brackets
from the rear end of the shafts; a long axle is employed, upon which
the wheels can revolve freely, and the wheels are held in position by
collars fixed to the axle ou cither side of it by set screws, and by varying
the position of the collars upon the axle the wheels can be set in any
desired position upon it. The axle may also be shifted endwise in a
similar manner through its bearings in the brackets. The brackets also
carry hooks, from which are suspended lever arms which have handles
connected to them at their rear ends, and have also fixed to them a pair
of horizontal bars, to which the several hoes are connected. The hori
zontal bars are suspended by chains which are passed around the ends
of a barrel carried by a frame projecting from the shafts in rear of the
axle, and by winding up the chain upon this barrel the hoes can be
raised or lowered, and so set to cut at any desired depth; the hoes are
guided in the ordinary manner by the man holding the lever handles,
and to enable this man also to raise or lower the hoes without stopping
the machine the barrel at its centre has jointed to it a number of lever
arms, by which he may turn it; each arm is connected by a link or
chain to a slide capable of moving endwise upon the barrel; this slide
has collars upon it, between which is received one end of a rod, which
passes through a slot or recess in one of the fixed bearings that carry the
barrel. When the slide is moved away from the lever arms the opposite
end of the rod enters into notches or recesses formed in a wheel which
is fast upon the barrel, and so locks the barrel from turning. Thus
whilst the man steers the hocs with one hand he can with the other
hand lay hold of one of the lever handles, and by turning it on its hinge
bring it into a position at right angles to the barrel; this moves the

page_text: slide above mentioned along the shaft, and by so doing withdraws the
rod from the notches or recesses in the wheel and sets the barrel free, so
that the man can turn it in either direction by the lever handle, .and
when he has thus either sufficiently raised or lowered the hoes he can
again lock the axle by allowing the lever arms to turn back into
their former position and the slide to shift endwise along the axle. A
spring is used to pull or push the slide into a position to lock the
barrel.
The stems of the several hoes are fixed by clips to the two paralled
bars above mentioned, and these bars are also fixed by clips to the lever
handles, so that the bar, together with the hoes carried by it, can be
set oither centrally or to project to a greater or less extent to one side or
other of the machine.
The hoes can also be set at any desired distance apart from one
another upon the bars.
Two sets of bars, each carrying hoes, can also be fixed one in front of
the other to the lever handles, so that one set of hoes may be in advance
of the other. The two parallel bars which carry the hoes are one above
the other. The stem of each hoe is received into a notch in a block
which lies between the parallel bars. Each block has a horizontal slot
formed in it, through which is passed a clip which embraces the stem
of the hoc and draws it tightly against the frontage of the bars, there
being a nut screwed on to a stem at the back of the clip which bears
against the back edge of the bars.
The clips by which the bars are secured to the lever handles are
formed in the following manner:-Each lever has a block secured to it,
from the front of which a pin projects; this pin passes between the two
horizontal bars and through a clip piece. A nut is screwed on to the
end of the pin, which presses the clip piece against the bars and holds
them against inclines on the block. The inclines draw the bars inwards
towards the pin, and thus hold the bars securely.
In order that my Invention may be fully understood and readily
carried into effect, I have shewn in the Drawings hereunto annexed. a
horse hoc constructed according to my Invention.
Figure 1 shews a plan view, partly in section, of the horse hoe, the
apparatus for lifting the hoes being removed; Figure 2 is a plan view,

page_text: shewing the lifting gear; and Figure 3 is a side view. The other views.
shew some of the parts separately.
a is the axle, upon which the wheels can revolve freely; c, c, are
collars fixed to the axle on either side of the wheels by set screws c', so
that the wheels may be retained in any desired position upon the axle.
The axle passes through the brackets d, which extend downwards from
the rear end of the shafts e; and there are other collars, retained by set
screws upon the axle, which come on either side of the brackets, by
which means the axle can be set to project to any desired extent from
either side of the machine. On each bracket is a hook f, which can be
fixed to it at any height desired; from these are suspended lever arms g,
which have handles connected to them at their rear end. The levers g
have horizontal bars / fixed to them by clips ¹ constructed as herein-
before described in Figure 3; the clips are formed to hold two sets of
bars to carry two sets of hoes, one in front of the other; but they may
if desired be formed so as to carry but one set of hoes, as shewn in the
separate views of the clips; the clips are themselves secured to the levers
in the manner shewn at Figure 3; one of the clamps by which the stems
of the hocs are held to the bars k is shown at Figures 4.
It will be seen that by fixing the stems of the hoes to the bars and
the bars to the levers by clips, in the manner above described, that the
hoes can be set at any desired distance apart, and can also be set to extend
to a greater or less extent to either one side or other of the machine, as
desired. The horizontal bars k are suspended by chains which pass
around the ends of a barrel m; this barrel is carried by arms n which
extend from the rear end of the shafts, as shewn at Figure 3; o, o, are
lever arms jointed to the barrel; each arm is connected by a chain to a
slide p; upon this slide are collars p', between which is received one end
of the rod q, the opposite end of which passes through a guide n¹ fixed
to one of the bars n. On the axis of the barrel is a notched wheel »,
and the end of the rod q is pushed forward into one or other of the
notches of this wheel by a spiral spring s, as shown, and the barrel is
by this means prevented from turning.
When it is desired either to raise or lower the hoes one of the lever
arms o is turned into a position at right angles with the axis of the
barrel m, thereby withdrawing the rod q from the notched wheel » and
setting the barrel free to turn; the barrel can then be turned in either

page_text: direction by the lever handle, and when the hoes have been thus raised
or lowered to the extent desired the lever arm is turned into the position
shewn at Figure 2, and the catch rod q will again be forced forward by
the springs into one or other of the notches of the notched wheel and
again lock the barrel and hold it from turning. Thus whilst the man
steers the hoes with one hand he can with the other hand either raise or
lower the hoes without stopping the machine.
Having thus described the nature of my Invention, and the manner
of performing the same, I would have it understood that I claim as my
improvements in horse hoes,----
1. The combined arrangement of horse hoe, substantially as herein
described and illustrated in the Drawings annexed.
2. Securing the axle to the frame and retaining the wheels upon the
axle by means of collars in the manner herein described.
3. The combined arrangement of barrel m with lever arms o and
catch for raising or lowering the hoes, substantially as herein
described.
4. Securing the stems of the hoes to parallel bars / by clips, sub-
stantially as herein described.
I
5. Securing the bars to the levers by clips, substantially as herein
described and shewn at Figure 3 of the Drawings.
In witness whereof, I, the said Edward Stacey Spencer, have here-
unto set my hand and scal, this Twenty-second day of December,
in the year of our Lord One thousand eight hundred and seventy-
four.
EDWARD STACEY SPENCER. (L.S.)
