An Improvement in and connected with Portable Harmoniums.
I, GEORGE JONES of 350, Commercial Road, London, E. Musical Instrument
Maker, 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 :-
My invention relates to an improvement in and connected with portable
harmoniums and has for its object to provide an improved method and means for
conducting the air from the foot bellows, to the air chamber or reservoir.
In harmoniums as hitherto constructed this is effected by conducting the air
through a passage or channel formed in each leg or support, but as it is necessary
that the said legs or supports should be capable of being folded, great difficulty is
experienced in making a tight joint between the edges when the legs or supports
are raised and in use, this results in a considerable loss of wind, necessitating
additional exertion on the part of the performer, to keep the air chamber or
reservoir supplied, while it is further unsatisfactory in Botion.
Now according to my invention I provide means in the form of a flexible tube
for conducting the air from the foot bellows to the air chamber or reservoir,
whereby little or no air is lost, and in carrying same into practical effect I take a
tube of india-rubber or other flexible material which is let into a groove or channel
formed in the leg or support of the instrument, or placed in any convenient and
suitable position, or two or more tubes may be employed let into grooves or
channels in the legs or supports. These tubes are furnished at their extremities
with flanged sockets so as to provide means whereby the ends of the tubes may be
attached to the air chamber and foot bellows, so as to be thoroughly air-tight.
In order that my invention may be more fully understood I will now proceed to
describe same with reference to the accompanying drawings in which
Fig. 1 is a general view of a portable harmonium fitted with my improved meanS
for conducting the air from the foot bellows to the air chamber or reservoir.
Fig. 2 shows a side view, edge view, and cross section of one of the legs or
supports with the air tube attached and
Fig. 3 shows an air tube with connections at an enlarged scale.
According to my invention the air tubes a are let into grooves or channels c
formed in the leg or support 7 of the instrument. The air tube a may be partly
within a straight recess formed wholly on one side of the leg or support of the
instrument as in Fig. 1 or the said tube a may pass through the leg near the hinge,
round same and out again at the front, continuing down the front of the leg or
aupport as in Fig. 1.
The ends of the tubes a are furnished with flanged sockets to which the
tubes are solutioned, cemented, or attached in any suitable manner while the
flanged part is secured to the foot bellows and air chamber or reservoir by means
of screws or in any other suitable manner, while a rubber washer or the like may
be employed for making a tight joint.
Having now particularly described and ascertained the nature of my said inven
tion, and in what manner the same is to be performed, I declare that what I
olaim is :-
The new or improved means for conducting the air from the foot bellows to the
air chamber or reservoir consisting of the flexible tubes a resting in grooves or

page_text: channels c of the supports or legs of the instrument, or conveniently placed, and
furnished with flanged sockets s substantially as herein described and shown and
for the purposes specified.
