Improvements in and relating to Refrigerating and Ice-making
Machines.
We, FREDERICK Barker Hill, of 27 Culmore Road, Peckham, in the County of
Surrey, Engineer, and JAMES SINCLAIR, of 114 Cannon Street, in the City of
London Fire Engineer, do hereby declare the nature of this invention to be as
follows:-
"Our invention relates to refrigerating and ice-making machines and its main object
is to provide a machine of this kind or class which will be very advantageous for
military and other purposes.
An important feature. of our said invention is the construction of a machine
mounted upon wheels in such a manner that it can be very readily transported or moved
from place to place and the mechanism for producing the cold can be driven by the
tractive force applied to the machine.
Another feature of our said invention consists in so constructing the said machine
that, while it is stationary, the mechanism for producing the cold can be driven by a
horse or other animal moving in a circular path or by manual power or by other suitable
means:
Another feature of our said invention is the provision of means whereby the con-
densation of the ammoniacal gas or other refrigerating agent may be effected either
by means of water or by means of atmospheric air.
Our said invention is conveniently and advantageously carried into practice as
follows that is to say, the wheels are mounted upon an axle which is fixed in or forms
a part of a suitable frame. This frame is provided with a platform for supporting
the ice-box or cooling chamber, the condenser and the pump. One of the said wheels
is fixed upon or designed to be connected with a sleeve fitted to rotate upon the axle
and connected by suitable gearing with the said pump. On the said sleeve is fitted
to rotate another sleeve which is also connected by suitable gearing with the said
pump. A pulley is fixed on the outer. sleeve and is connected by a belt with another
pulley fixed on a horizontal shaft. This shaft has fixed thereon a bevel pinion with
which is geared a bevel wheel fitted to rotate upon a vertical stud or shaft and
provided with a socket for the reception of one end of a pole. The other end of this
pole is adapted for the attachment thereto of a horse or other animal. This pole
will serve either for transporting the machine or for driving the mechanism for
producing the cold. Suitable means are provided for putting the said mechanism into
and out of gear with the said bevel wheel or with the road-wheel.
The said frame is provided with flaps or hinged pieces which may be turned down
and secured to the ground when the machine is stationary.
We sometimes make the condenser so that it can be used with either water or air as
the cooling medium. Or we provide two condensers, one for use with water and the
other for use with air.
It is obvious that the construction and arrangement of the mechanism may be
somewhat modified without departing from the nature of our said invention.

Improvements in and relating to Refrigerating and Ice-making
Machines.
I, FREDERICK BARKER HILL, of 27 Culmore Road, Peckham in the County of
Surrey, Engineer and JAMES SINCLAIR of 114 Cannon Street in the City of London
Fire-Engineer, 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 :-
Our invention relates to refrigerating and ice-making machines and its main object
is to provide machines of this kind or class which will be very advantageous for
military and other purposes.
An important feature of our said invention is the construction of a refrigerating
and ice-making machine mounted upon wheels so that it can be very readily trans-
ported or moved from place to place and provided with mechanism which can be
driven, during transport, by the tractive force applied to the machine, for the purpose
of producing the cold.
Another feature of our said invention is the provision of suitable means whereby,
while the machine is stationary, that is to say, when no tractive force is applied to it,
the mechanism for producing the cold can be driven by a horse or other animal.
moving in a circular path around the said machine. In some instances, however, we
provide for operating the said mechanism, while the machine is stationary by manual
power or by other suitable means.
Another feature of our said invention is the provision of suitable means whereby
the condensation of the ammoniacal gas or other refrigerating agent may be effected
by means of either water or atmospheric air.
In the accompanying drawings we have shown how our said invention may be con-
veniently and advantageously carried into practice.
Figure 1 is a perspective view showing one form or modification of our improved
apparatus.
Figure 2 is a transverse section drawn to an enlarged scale, showing details of
construction.
Like letters indicate corresponding parts throughout the drawings.
A is the frame of the machine, B is the axle, C C¹ are the road or travelling
wheels, is the ice-box or cooling-chamber, E is the condenser, F is the pump.
The wheel C is firmly fixed on a sleeve a fitted to rotate freely upon the axle B
which is rigidly secured to the frame A. b is a toothed wheel keyed or otherwise
firmly fixed upon the said sleeve a. The toothed wheel b is geared with another
toothed wheel c mounted (as hereinafter described) upon the driving shaft d of the
machine which is carried in suitable bearings e in the frame A and in the casing of the
pump F. The said shaft d is arranged to work the pump F in any suitable manner,
and may be rotated through the medium of the toothed wheels b, c, by the road-
wheel C, during transport of the machine.
We thus provide for very conveniently and advantageously producing cold while
the machine is being moved from one place to another.
For imparting rotary motion to the said driving shaft d when the machine is
stationary, we provide the following mechanism, that is to say, a crown-wheel fis
keyed or otherwise firmly fixed on a vertical shaft g supported in a suitable bearing h
in the frame A and in a footstep bearing i provided in an enlargement. of the
axle B. is a socket formed on or firmly attached to the boss fl of the said crown
wheel f.k is a pole one extremity of which is fitted into the said socket j, and the
other, extremity of which is provided with a cross-tree or whipple-tree for the
attachment thereto of a horse or other animal. m is a shaft or spindle supported in
suitable bearings n upon the frame A and having keyed or otherwise firmly fixed

page_text: thereon a bevel wheel or mitre wheel o which is geared with the said crown-wheel f.
p is a sprocket or chain wheel also fixed upon the shaft or spindle m. The sprocket
or chain wheel p is connected by means of a suitable chain r, to another sprocket or
chain wheel formed with or firmly fixed on a sleeve s arranged to rotate freely
upon the sleeve a. t is a toothed wheel formed with or firmly fixed on the said
sleeve s.
u is a toothed wheel formed with or firmly attached to the toothed wheel c.
The toothed wheels and c are arranged to slide longitudinally upon the driving-
shaft d, but are prevented from turning thereon by means of a key fitted to slide in a
groove d' in the said shaft.
By shifting the said toothed wheels u and c upon the shaft d, either the toothed
wheel c and b, or the toothed wheels u and t can be put into gear, and the shaft d
thus connected either to the road-wheel C, or to the crown-wheel f. vis a set-screw
for securing the said toothed wheels u and c in either position upon the driving
shaft d.
w, w are hinged pieces or supports which are to be turned down into the position
shown in the drawings when the machine is stationary, so as to support the platform A
but which can be folded up out of the way when the machine is to be transported
from one place to another.
The driving-shaft d can therefore be operated by the road-wheel C whilst the
apparatus is being transported, or by a horse or other animal attached to the pole k
and moving in a circular path around the machine, when the said machine is not
being transported.
The pole serves also for transporting the machine. In this case the said pole is
secured to the crown-wheel by straps or stays to prevent or diminish vibration
and a bolt or pin is passed through holes provided in the frame A and in the crown-
wheel to secure the latter rigidly in position.
The ice-box or cooling-chamber D, condenser E and pump F may be of any
suitable construction. The manner in which the machine is operated will be readily
understood from the foregoing description. The refrigerating apparatus may be con-
structed as described in the Specification of former Letters Patent No. 13487 dated
5th October 1887 or in any other convenient manner.
It is obvious that the construction and arrangement of the mechanism may be
somewhat modified without departing from the nature of our said invention. For
instance we sometimes make the condenser so that it can be used with either water
or air as the cooling medium. Or we provide two condensers, one for use with water
and the other for use with air. In the latter case we provide a suitable fan or blower
arranged to be driven from the driving shaft d.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we wish it understood
that we claim :-
First. A refrigerator or ice-making machine mounted upon wheels and provided
with suitable means whereby motion may be transmitted to its driving-shaft from one
of the said wheels during transport, for the purpose above specified.
Second. A refrigerator or ice-making machine mounted upon wheels and provided
with suitable means whereby it may be operated by a horse or other animal moving
around it.
Third. A refrigerator or ice-making machine mounted upon wheels in combina-
tion with suitable mechanism whereby motion may be transmitted to its driving-
shaft from one of the said wheels during transport, and from another shaft operated
by horse or other power while the machine is stationary, substantially as herein before
described.
Fourth. A refrigerator or ice-making machine wherein provision is made for con-
densing the ammoniacal gas or other refrigerating agent by means of either water
or air, substantially as herein before described.

page_text: Fifth. The improved apparatus constructed substantially as described with
reference to the accompanying drawing and operating as, and for the purposes, above
specified.
