It has been necessary heretofore
to maintaina section of automatic looms to weave

weave the fancier fabrics.
It is an important
object of my present invention to provide a loom
having the automatic weaving instrumentalities
in place when weaving simple box patterns, but
capable of being swung to inactive position on
the loom to permit the addition of drop boxes
at the magazine end of the loom. The magazine
is mounted so that it can be thrown up to a

Referring to the drawings, I have shown a loom
which is adapted for weaving either 4x1 or 4x4,
that is, four boxes at one end and one at the
other, or four boxes at each end, although the in
vention is not limited to the speci?c number of
between the top of the magazine and the loom
arches to prevent undue vibration. It is a fur
ther object of my present invention to modify
shuttle boxes set forth herein. The magazine is 35
of the customary multicolor type and follows a
construction which has gone into general use, be

about which the magazine can be swung to in

automatic to non-automatic pick and pick. '
'When the loom is weaving automatically the
magazine is ‘generally located with a portion
thereof nearer the center of the loom. than the
adjacent ends of the arches. It is another object
of my invention to provide a brace preferably
so constructed as to permit an endwise sliding
of the magazine away from the center of the loom
so that'the arches will not interfere with the
magazine as the latter is ‘pivoted to idle position.
A still further object of the invention relates to

80 of shuttle cells, is lifted upwardly out of the
loom, the chain 98, however, remaining attached
to the sleeve 96 and the rod 99 together with the
spring I02 acting in normal manner. The rela
tion of parts is such that even should the chain
98 move in response to pattern chain indica
tions there will be no resultant interference be
cause the chain and the parts operated thereby
lie behind the spent bobbin can I 05, shown in'
Fig. 3, and are below the bobbin chute £06 down

of the mechanism which operates the gang of
boxes 89 can be left on the loom when the latter
is operating automatically.

From the foregoing it will be seen that I have
provided simple means whereby a loom may be
used either to operate automatically with a maga
zine to supply reserve bobbins, or non-automati
cally to weave a more elaborate pattern calling for

seen that the plate 85 is readily removable when
