IMPROVEMENTS IN HORSE MILLS
Year: 1884

page_text: I RICHARD HEBER RADFORD of High Court Chambers 35 High Street Sheffield
in the County of York Consulting Engineer of the London and Provincial Patent
Agency, do hereby declare the nature of the said Invention for IMPROVEMENTS IN
HORSE MILLS communicated to me from abroad by Hermann Edelmann of
Perleberg in the German Empire to be as follows:―
Horse Mills hitherto in use especially those driven by a bevil main wheel and
spur gearing fixed within their frame, have defects which may be completely over-
cone by the Improved Horse Mill herein described. The fixing and carrying from
place to place of such Mills has hitherto been difficult, owing to a portion of the
Gearing extending below the level of the frame or foundation plate of the Mill,
this causes a difficulty not only in transporting but also in fixing the Mills.
especially in paved places;-In the Improved Mill two sets of Gearing are employed,
instead of a single set as in the Old Mills, but the Gearing is so arranged as not
to extend below the lower surface of the foundation plate of the Mill, the fixing
and transport are by this improved construction greatly facilitated, and at the
same time a simple Portable Mill is obtained.
By fixing a clutch or claw coupling on the shaft of the bevil driving wheel and
upon that of the spur wheel gearing in Mills hitherto used only two different
speeds could be produced according to the proportion of the wheels, whereas in the
Improved Mill by an arrangement of double gearing and by fixing an universal
swivel joint at the ends of the shafts, three different speeds may be obtained, as
for example with the proportions of the Gearing as shewn in the accompanying
drawings Speeds of Twenty Forty and one hundred revolutions per minute of the
transmitting Shaft may be attained. By the production of a medium speed, a
want which has been felt in many instances is supplied.

page_text: All the revolving parts of the Mill are supported upon a foundation plate G
which with the four bearings f, of the two Horizontal shafts d, and i and the
boss C for the fixed vertical shaft b forms a compact frame, immovable in its
separate parts, Around the axis of the fixed vertical shaft b turns the large bevil
main wheel a, which is fitted with sockets r. and draw poles, 8. into this main or
driving wheel is Geared the bevil pinion wheel e keyed upon the horizontal
shaft d. The main wheel a, being steadied in gear by the guide or Friction pulley T.
The shaft d, so called the bevil shaft rests in a pedestal f, and is guided in a
bearing within the boss C behind the boss C the bevil shaft carries the spur
wheel g, which gears into the pinion h, fixed upon the countershaft i.
The spur
wheel, l, keyed upon the countershaft i, gears into the pinion k, this pinion k, turns
loose upon the bevil shaft d and forms with its boss a coupling claw M.
According to the connection of the transmission shaft with this coupling claw,
or with a coupling claw fixed to the ends of the shaft i, or with a claw at the
inner end p, of the shaft d, three different speeds are produced for the transmission
of power.
The advantages of the above described arrangement of wheels consists in the
production of three different speeds with only two shafts and a double set of
Gearing also by means of claw couplings at both ends of the shaft i, the trans-
mitting shaft can be made to turn to the right as well as to the left without
changing the direction of the movement of the Horses, or Cattle from right to left
a way always preferred by the Farmer.
If the cattle go round a left hand way the pinion k, can make room in the
direction whence the bevil wheel received its pressure by which means the side
pressure is taken off the bearing f.
As the pinion k, turns in the same direction as the shaft d, it will be consuming
in its bearing less lubricating substance and will have less friction upon the axle
than it would if fixed upon an axle running in two bearings.
If the bevil shaft d, makes Twenty revolutions per minute, the pinion k not-
withstanding its one hundred revolutions per minute (if the proportion is one to
five) will only make eighty revolutions around the axis of the shaft d.
The lubricating apparatus arranged for the pinion k, is as follows; upon a Boss
or neck of the pinion is cast the grease box n, closed by a brass screw Q, at the
bottom of this box below the inlet a small metallic pipe is inserted, at the sides of
this pipe there are in the bottom of the grease box two air holes the oil in the
grease box n, is actuated by the centrifugal force, created by the rapid revolutions
of the pinion k and forced through the fine opening of the pipe backwards on to
the shaft to supply the same with the required lubricating substance. The holes
in the bottom of the Grease box are for the admission of air as the oil could not
flow out without one of the holes serves for the right hand motion the other for
the left hand motion of the pinion.

I RICHARD HEBER RADFORD, of 15 St James Row, Sheffield in the County
of York, Consulting Engineer, of the London and Provincial Patent Agency, do
hereby declare the nature of the said Invention, for, "IMPROVEMENTS IN HORSE
MILLS, communicated to me from abroad, by Hermann Edelmann, of Perleberg,
in the German Empire, and in what manner the same is to be performed, to be
particularly described, and ascertained, in and by the following statement:―
Horse Mills hitherto in use, especially those driven by a bevel main wheel, and
spur gearing fixed within their frame, have defects, which may be completely
overcome by the Improved Horse Mill herein described.
The fixing and carrying from place to place of such mills has hitherto been
difficult, owing to a portion of the Gearing extending below the level of the frame
or foundation plate of the Mill, this causes a difficulty not only in transporting, but
also in fixing the Mills, especially in paved places.
In the Improved Mill two sets of Gearing are employed, instead of a single set
as in the old Mills, but the Gearing is so arranged as not to extend below the
lower surface of the foundation plate of the Mill, the fixing and transport are by
this improved construction greatly facilitated, and at the sime time a simple,
Portable Mill is obtained.
By fixing a clutch or claw coupling on the shaft of the bevel driving wheel and
upon that of the spur wheel gearing in Mills hitherto used, only two different
speeds could be produced according to the proportion of the wheels, whereas in
the Improved Mill by an arrangement of double gearing and by fixing an uneversal
swivel joint at the ends of the shafts, three different speeds may be obtained, as for
example with the proportions of the gearing as shewn in the accompanying
drawings, speeds of Twenty, Forty, and One hundred revolutions per minute of the
transmitting shaft may be attained. By the production of a medium speed, a want
which has been felt in many instances is supplied.
In the Drawings accompanying my Provisional Specification
Fig. 1, Represents the longitudinal elevation in section of the improved Mill.
Fig. 2, Is the Plan partly in section with the bevel wheel a, removed.
Fig. 3, The end elevation of the same.
Figs. 4, and 5, Represent an enlarged view of the Lubricating apparatus of the
second set of spur wheel gearing as shewn at C. D. and E. F.
All the revolving parts of the Mill are supported upon a foundation plate G,
which with the four bearings f of the two Horizontal shafts d and i, and the boss c,
for the fixed vertical shaft b, forms a compact frame, immovable in its separate
parts; around the Axis of the fixed vertical shaft b, turns the large bevil main
wheel a, which is fitted with sockets r, and draw poles s; into this main or driving
wheel is geared the bevel pinion wheel e, keyed upon the horizontal shaft d, The
main wheel a, being steadied in gear by the guide or friction pulley t. The shaft d,
BO called the bevil shaft rests in a pedestal f, and is guided in a bearing f, within
the boss c. Behind the boss c, the bevil shaft carries the spur wheel g, which gears
into the pinion h, fixed upon the countershaft. The spur wheel Z, keyed upon
the countershaft i, gears into the pinion k, this pinion turns loose upon the bevil
shaft d, and forms with its boss a coupling claw m.

page_text: According to the connection of the transmission shaft with this coupling claw, or
with a coupling claw fixed to the ends of the shaft i, or with a claw at the inner
end p, of the shaft d, three different speeds are produced for the transmission
of power.
The advantages of the above described arrangement of wheels consists in the
production of three different speeds with only two shafts, and a double set of
gearing, also by means of claw couplings at both ends of the shaft i, the
transmitting shaft can be made to turn to the right, as well as to the left, without
changing the direction of the movement of the Horses or Cattle from right to left a
way always preferred by the farmer.
The side pressure is taken off the bearing f when the cattle go round left hand,
as then the pinion k, can give way in the direction whence the bevel wheel receives
its pressure.
As the pinion k, turns in the same direction as the shaft d, it will be consuming
in its bearing less lubricating substance, and will have less friction upon its axle
than it would if fixed upon an axle running in two bearings.
If the bevel shaf d, makes, Twenty revolutions per minute the pinion k not.
withstanding its hundred revolutions per minute (if the proportion is one to five)
will only make eighty revolutions around the Axis of the shaft d.
The lubricating apparatus arranged for the pinion k, is as follows:-upon a boss,
or neck, of the pinion is cast the grease box n, closed by a Brass screw Q, at the
bottom of this box, below the inlet.a small metallic pipe is inserted, at the sides of
this pipe there are in the bottom of the grease box two air holes; the oil in the
grease box n, is actuated by the centrifugal force, created by the rapid revolutions
of the pinion k, and forced through the fine opening of the pipe backwards on to
the shaft, to supply the same with the required lubricating substance. The holes in
the bottom of the grease box are for the admission of air, as the oil could not flow
out without; one of the holes serves for the right hand motion, the other for the
left hand motion of the pinion.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is
1. In place of the hitherto employed single spur wheel gearing, two sets of spur
wheel gearings upon two horizontal shafts are employed and arranged in such
a manner that the pinion k, fitted with a coupling claw revolves loosely upon
its shaft.
2. The horizontal shaft d, is supported in the boss c, cast upon and in one piece
with the foundation plate G.
3. The claw pinion k, which revolves loosely upon its shaft is supplied with a
self acting lubricating apparatus acting by means of centrifugal force.
4. Three different speeds for the transmitting shaft can be produced with only
two horizontal shafts supported in bearings attached to the Foundation plate G.
5. Improvements in Horse Mills substantially as herein described and illustrated
by the accompanying drawings.
