IMPROVED APPARATUS FOR CONTAINING AND CONVEYING HEATED RIVETS."
The object of my Invention is to provide apparatus whereby hot rivets can be
conveyed from a furnace to a rivetting machine or elsewhere without material
loss of heat and with reduced labour. The great advantage resulting is better
and much more work in rivetting inasmuch as the rivets are well kept at the
required beat.
The Invention is especially applicable in connection with portable rivetting
machines, which are often worked at a considerable distance from the rivet
heating furnace. Much difficulty has been experienced in getting the full
compliment of work from these machines, as so few rivets can, with the present open
vessel, be brought to them at one time and kept hot, besides the very frequent
opening of the furnace for withdrawing small quantities interferes with the proper
heating of the rivets.
The apparatus consists essentially of a double cased vessel or container of metal
or other material of any suitable shape having the space between the double walls
occupied by a heat non-conducting agent. Asbestos is the agent preferred, but
silicate cotton and other non-conducting substances may be used, and so also may

non-conducting substance, such as asbestos or fire clay.

"IMPROVED APPARATUS FOR CONTAINING AND CONVEYING HEATED RIVETS."
The object of my Invention is to provide apparatus whereby hot rivets can be
conveyed from a furnace to a rivetting machine or elsewhere without material loss
of heat and with reduced labour. The great advantage resulting is better and
much more work in rivetting inasmuch as the rivets are well kept at the required
heat.
The Invention is especially applicable in connection with portable rivetting
machines, which are often worked at a considerable distance from the rivet heating
furnace. Much difficulty has been experienced in getting the full compliment of
work from these machines, as so few rivets can, with the present open vessel, be
brought to them at one time and kept hot, besides the very frequent opening of
the furnace for withdrawing small quantities interferes with the proper heating of
the rivets.
The apparatus consists essentially of a double cased vessel or container of metal
or other material of any suitable shape having the space between the double walls
occupied by a heat non-conducting agent. Asbestos is the agent preferred, but
silicate cotton and other non-conducting substances may be used, and so also
may a jacket of air or gas; or a vessel or rivet holder may be made altogether of a
heat non-conducting substance, such as asbestos or fire clay.
One form of the apparatus is made principally of cast or wrought iron, and is
provided with a balanced or other covering lid, and also a carrying bow, the latter
connected to trunnions or centre studs at opposite sides. When filled or charged
it is turned over, so that the lid is downwards. Catches hold the turned over
apparatus and bow in position, and fit the whole for easy carriage by two men
with a bar. A tripod or other appliance may be used to suspend it whilst the
rivets are being taken out and used in smaller vessels carried in hand.
In some cases the apparatus may be mounted on wheels or slides.
But, as will be obvious, many modifications may be made under my Invention.
DESCRIPTION OF THE DRAWINGS.
t
Fig. 1 is a sectional elevation, Fig. 2 a side elevation, Fig. 3 a plan view, and
Fig. 4 a view with the lid open, all of a modification of apparatus under my
Invention for containing and conveying heated rivets. The space for containing
rivets is at R, and is formed by inner walls a and outer walls b. The space c.
between the said walls is filled with asbestos or other suitable non-conductor of
heat. d, cover or lid hinged at e, and provided with a balance weight f for closing
the said cover or lid; y, catch for retaining the cover or lid d in position when
closed; h, conveying or carrying bow connected to the chamber or vessel a by
trunnions ; j, catches to retain the chamber or vessel in inverted position for easy
carrying and for retention of heat. When it is desired to quickly discharge the
rivets the catch g is released, when the contents fall out. In Figs. 1, 2, and 3 the
lid is downwards in position for carrying or conveying, whilst in Fig. 4 it is at the
top open, as for filling.
Fig. 5 is a plan view, Fig. 6 a side elevation, and Fig. 7 a sectional elevation of
a modification of apparatus, under my Invention. The inner and outer walls a, b,
of the chamber or vessel are here of wrought iron or steel, and the said chamber or
vessel is suspended from the bow h by the lugs j. d, metal cover or lid; k, ring

page_text: used in tilting the chamber or vessel when it is desired to turn out the contents.
The above apparatus can be made lighter and more suitable for moving by hand
than that described under Figs. 1, 2, 3, and 4.
It will be obvious that the containers or vessels may be of any desired shape
and size, and that although they are specially fitted for carrying in a person's hand,
cranes, trucks, or other appliances may be used in conveying them from place to
place.
Having now described and ascertained the nature of the said Invention, in such
manner that others will be enabled to carry my improvements into effect, I
claim,―
The apparatus for containing and conveying heated rivets constructed sub-
stantially in the manner and having the advantages herein set forth.
In witness whereof, I, the said Walter Mac Lellan, have hereunto set my
hand and seal, this Nineteenth day of November, in the year of our
Lord One thousand eight hundred and eighty.
