Improvements in Domestic Garbage Dryers or Carbonizers.
We, GEORGE TAYLOR, of 113 Devonshire Street, Boston, in the County of
Suffolk, and MARTIN BERNARD MCLAUTHLIN, of Malden in the County of
Middlesex, both in the State of Massachusetts, United States of America,
Gentlemen, 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 :-
This invention relates to an improvement in domestic garbage dryers or
carbonizers, and consists in the novel features of construction and relative
arrangement of parts hereinafter fully described in the Specification, clearly
illustrated in the drawing, and particularly pointed out in the claims.
Reference is to be had to the accompanying one sheet of drawing forming a
part of this Specification in which like characters indicate like parts wherever
they occur.
In the drawing
Fig. 1 is a perspective view of our invention;
Fig. 2 a longitudinal vertical section;
Fig. 3 a transverse vertical section and
Fig. 4 a sectional plan.
A is the opening or flue, the rim of which is made to fit the range so as to
become a fixture therewith and a part of it.
B is the opening or flue, the rim of which is made to fit closely any chimney
flue or connecting length of piping.
C is a cylinder made preferably of sheet metal into the interior of which the
openings A and B communicate. The drawing shows the one opening at a right
angle to the other but it is expressly understood that they may be linear, or in
any other way communicating with each other.
D is shown as a sheet metal head, which, however, may be made of cast-metal ;
it is provided with the rabbetted edge d for a shouldered and close insertion to the
cylinder C, which close fit is amply sufficient to secure tight joints and to hold
secure in place.
D' is another head made preferably of cast-metal to close the opposite end of
the cylinder, and is composed of a ring E and a door F. This ring or frame E
is provided with a rabbetted edge e to limit its insertion into the cylinder, and it is
also provided with hooks e'. The door F is provided with projections for
engagement with the hooks el which serve as fastenings to hold the door to the
frame. The door F is further provided with a suitable handle G by means of
which the door may be entirely removed from the frame and replaced.
The door may be provided with the ordinary swinging hinges, or other fastening,
but the foregoing is preferred.
The handle G is made of non-conducting material or in such manner that the
heat is not transmitted thereto from the door.
H. is the hopper or receptacle to hold or contain the garbage during its
incineration; it is shown as scoop-shaped, but may be modified without in any
way impairing its functions. This hopper is of such size as compared with the
cylinder G as to allow of ample flue capacity between it and the cylinder, and that
the said hopper does not retard the natural draft of the range. It is provided
with a series of onenings or verforations in its sides down to a prescribed level,

page_text: below which it is tight so as to hold a liquid. The openings'h'are to allow the
heated gases to permeate the garbage and thus the heated gases pass directly
through the hopper and the contained garbage. The hopper is secured to the door
in any substantial manner, but preferably as shown in Fig. 2, by sleeves 9 9 and
bolts g'g', the sleeves placed between the hopper and the door with the bolts
passing through and binding all together and making the parts to all intent and
purpose integral.
I is a partition placed longitudinally with the cylinder and shown in Fig. 3;
it is placed at the best point by which the draft is forced the furthest distance
from inlet to outlet, it deflects the natural tendency of the draft in another
direction, it may be secured either to the chamber or the receptacle.
J is a hot shelf arranged on top of the cylinder simply as a convenience to
ordinary household work.
In operation its use is as follows:
Heated gases from the range are entering the chamber through the opening A
and leaving through the opening B. Taking hold of the handle G and lifting the
projections fout of engagement with the hooks eel the hopper is removed from
the chamber within the cylinder and the garbage is dumped in. The hopper and
door are now replaced and the garbage is in the closed chamber with the heated
gases circulating through and around it.
The vegetable matter at once begins to dry and shrink, due to evaporation of
water, while greasy or fatty matter becomes fluid and is retained in the bottom
of the hopper until it ignites thereby effecting a higher degree of heat 'to hasten
the incineration of the whole mass, and at the same time destroying the odor
therefrom. The ignition is caused by admitting a sufficiency of air through the
range to supply oxygen to the hydrocarbons. In due time, generally when other
garbage is about to be introduced, the hopper is removed from the chamber and
the charred or incinerated contents are emptied into the fire of the range by which
all that remains is reduced to ash.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. A domestic garbage dryer or carbonizer comprising in its construction a closed
chamber provided with an inlet and an outlet opening, a hopper or receptacle in said
chamber provided with a closed bottom and perforated sides and a deflecting plate
in said chamber so located as to cause the products of combustion to contact the
refuse matter either through the perforations or at the top of the receptacle,
substantially as and for the purpose set forth.
2. A domestic garbage dryer or carbonizer comprising in its construction a
closed chamber provided with an inlet and outlet opening, and an open-top hopper
or receptacle provided with a closed bottom and perforated sides so located in
said chamber as to cause the products of combustion to contact the refuse matter
either through the perforations or at the top of the receptacle, substantially as
and for the purpose set forth.
