An Improved Folding Temperature-regulated Packing and
Storage Case, and Trolley therefor.
I, JOSEPH HENRY BOWLEY of Marengo, County McHenry, State of Illinois,
U.S.A., Travelling Salesman, do hereby declare the nature of this invention to be
as follows:-
The packing case of this invention is constructed with hinged duplicate folding
sides, ends, cover sections and partitions so as to divide the case into an upper
compartment for the goods which may be placed in another case carried on bearings
in the ends of the case of this invention, and into lower compartments severally
for heating, refrigerating and supplying air, these several lower compartments
communicating when necessary with the upper compartment through pipes fitted
with cocks and weighted valves. The heating compartment is supplied with heat
by any suitable means usual for heating railway carriages such as oil, or gas, or
electric heating coils. The refrigerating chamber is supplied for its purpose with
ice and distributes cold air through a perforated tube. The air supplying
compartment is charged with compressed air which is distributed to the upper
compartment through suitable tubes and valves.
The trolley comprises a rigid underframe supported on rollers; two ends folding
thereon each end consisting of two hollow uprights carrying extension bars movable
vertically therein the uprights being connected by a cross bar; a yielding floor
carried at each end by a rope in connection with a helical spring; two sides hinged
to and folding on to the floor and springs between the ends of the floor aud the
underframe.

An Improved Folding Temperature-regulated Packing and
Storage Case, and Trolley therefor.
I, JOSEPH HENRY BOWLEY of Marengo, County McHenry, State of Illinois,
U.S.A., Travelling Salesman, 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:
:-
The device of this invention is mainly designed for employment in connection
with the packing cases described in my Patent Specification No. 15394 of 1894.
The object of the invention is firstly to provide a folding temperature regulated
case to receive the packing case or cases which may be so controlled that the
temperature most suitable for the preservation of eggs or other perishable goods

page_text: The
may be maintained during storage or whilst being transported, and such means are
provided that goods liable to fracture may be handled with ease and safety.
improvement consists in certain communicating compartments having folding sides
and partitions arranged in such manner that a supply of air of proper temperature
may be obtained from warmed refrigerated and atmospheric air.
The object of the invention is secondly, to provide a trolley which also folds up
and is for the purpose of holding the cases upon a yielding platform suspended.
from a folding extension frame mounted upon wheels or rollers which will hold the
goods free from jars and jolts.
In the drawings
Fig. 1 is a longitudinal sectional view of a case of this invention with a portable
egg case carried therein.
Fig. 2 a sectional perspective view with one end, one side, and half the cover
removed and the partitions and cover section attached to the remaining sides and
bottom folded thereon, the other portions being foldable in a similar manner.
Fig. 3 a perspective view of the preferred form of folding trolley.
The egg case 51 is preferably constructed as described in my aforesaid Patent
Specification and is mounted to revolve upon trunnions 52 supported on spring
bearings 53 at the ends of the temperature regulated packing case 54 of this
invention, said bearings moving in vertical grooves 55 and being supported on
springs 56 which allow the egg case to be rotated at suitable intervals or
automatically as stated in my aforesaid Patent Specification.
The folding temperature regulated packing case 54 is made with folding sides 57,
ends 58, cover sections 59 and partitions 60, 61, 62, the latter being located at the
ends of the bottom chamber beneath the egg cases and providing an intermediate
chamber 63 for holding air at a suitable temperature regulated by weighted
valves 64 at the aperture 65 between the chamber 63 and the packing case
chamber 66, a check valve 67 placed at apertures at the top and ends of the
chamber 66 allowing the confined air to escape but excluding the exterior air.
The refrigerating chambers 69 at the ends of the case 54 and of the chamber 63
have slotted bottoms 70 to support ice and have perforated air distributing tubes 71
which conduct external air from the passage 72 to said refrigerating chambers, an
aperture 73 leading from the passage 72 and controlled by a stop cock 74 or check
valve serving for controlling the admission of the external air. An aperture 75 and
check valve 76 in each of the partitions 62 admits air from each of the chambers 69
to the chamber 63 when the air therein becomes reduced in pressure and
temperature.
A check valve regulated stop cock 77 in an air conduit pipe 78 at each end of
the chamber 66 leads to the air chamber 63 and regulates the admission of external
air to suid chamber without first passing through the refrigerating chambers 69
thus providing air for direct circulation under favourable conditions without
drawing from the refrigerating chambers. A heating chamber 79 underneath
partition 80 in the same plane as and between the air passages 72 is supplied with
heat by any suitable means, for instance such as is employed for heating railway
vehicles, or by means of oil, gas or electricity, the electric heating coils 81 at the
ends and the intermediate gas jets 82, illustrating the means preferably employed
for this purpose.
A perfect regulation of the temperature as well as the humidity of the air within
the goods holding chamber may thus be obtained and the rotation of the goods
holding case 51 may either be automatic as described in my aforesaid previous
Patent Specification, or from time to time, such rotation causing a more general
distribution of the cooled or heated air.
The various sides, ends, covers, partitions, and slotted bottoms of the refrigerating
and regulating chambers are hinged together in the manner shewn in Fig. 2. In
folding the temperature regulated case the sides 57 are turned to the floor 66 and
the ends then brought over the sides. The entire case will then occupy but a small

page_text: space. The egg or other goods holding case may be made to fold together in any
known or preferred manner.
The above described temperature regulated cases cannot be easily handled and
when resting upon the floor of railway vehicles or good waggons are subjected to
violent jolts both vertically and horizontally during transit, and they are very
heavy and cannot without special means be easily moved from place to place. To
remedy this difficulty I provide a trolley the preferred form of construction of
which is shewn in Fig. 3 and consists of a rectangular bed frame 83 supporting at
each end, posts 84 connected at their upper ends by cross bars 85, and at their
lower ends by hinges 86 to the bed frame 83, so that they may be folded down upon
the latter. 87 are angle irons secured to the upright posts and fixed by bolts 88 to
the bed frame when the trolley is in use. The posts 84 are made hollow and
extension bars 89 may be slid therein and be fixed in place by set screws 89* to
receive the temperature regulated cases which may be lashed thereto. A floor 90-
having two hinged folding side extensions 90* is supported at its ends by branches 91 ×
of a rope or chain 91 which passes over a pulley 92 supported by each cross bar 85,
and each rope or chain is attached by one of its ends to a spiral spring 93 which at
its opposite end is secured to the bed frame 83 and permits the floor to yield
vertically when the trolley is severely jolted, thus protecting the contents of the
packing cases from damage. A spiral spring 94 at each end of the floor 90 and
secured to it and to the bed frame relieve the load upon the trolley from horizontal
or end concussions. The bed frame 83 is supported upon trolley wheels 95 which
allow of easy movement from place to place of heavily loaded trolleys. When the
trolley after unloading, is to be folded, the sides 90x are folded upon the floor 90,
the bolts 88 released from the angle irons 87 and the posts with the cross bars.
folded down upon the floor, the whole in a convenient forin for storing or sending
away.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, declare that what.
