This invention relates to knitting machines and
more particularly to Galon machines for the knit
ting of curtains, trimmings and the like.
Machines of this type are old and well-known
5 and have been in use, substantially without
change, for many decades. As is well-known
by those skilled in this art, a machine of this type
includes a main camshaft having a plurality of
cams for operating the various moving portions
10 of the machine, to wit:—the needle bar, yam rod
fork, and take-up rolls. The machine also in
cludes certain other cams for operating the warp
bar, the pattern chain advancing and reversing
5 mechanism, etc.
Heretofore the machine per
15 formed one complete cycle of operation for each
revolution of the drive shaft and of the main cam
shaft, and, of course, the capacity of the machine

Fig. 6 is, a fragmentary detail of the ‘two to one‘ 10
drive between the drive shaft and one of the
pattern chains.
The machine, in the usual manner, is provided
with a. needle bar A, a warp bar B, a take-up
roll C, yam'rods D, yarn rod forks E for elevat 15

The machine is driven by means such as the
