' A further object of this invention is to set forth a ma
chine as above-described that will be economical, and that
may be easily mass-produced.
A further purpose of the invention is to set forth an
relative thereto and then retightening the said lock bolt.
The shaft actuating assembly mentioned above consists
35 primarily of an actuating cylinder 28, an actuating cylin~
intermittent stock feed machine that is both :safe and sim
ple to operate.
The invention further seeks to set forth a unit as above

described-that will be entirely safe in operation.
With these objects in view, the invention consists of
the novel features of construction and arrangement of
parts which will appear in the following speci?cation and
recited in the appended claims, reference being had to the
accompanying drawings in which the same reference 45
numerals indicate the same parts throughout the various '
?gures and in which:

The actuating cylinder 28- will have at least two pressure
inlet lines 29 and 301to operate the piston within the said
cylinder as desired. Connected forward of the actuating
cylinder connecting shaft 31 in a somewhat pivotal‘man
ner, to be described in detail immediately hereinafter, is
the shaft attaching member 32. It will be seen that the
shaft attaching member 32- and the connecting shaft 31
are joined by a relatively loose pin 34. Furthermore, the
said connecting shaft 31 will have a relatively rigid pro
jecting depending member 35 perpendicularly extending
therefrom on the'side away from the shaft 26. As best
seen in FIG. 2, the depending member 35 will be posi
tioned to bear against one face of the shaft actuating mem

A forward position of the shaft attaching member 32 is
shown in phantom in FIG. 2.

stroke of the actuating member 15 may be in?nitely con
trolled in addition to the in?nite control of each of the
individual advance strokes, as hereinabove described.
It will be seen then that there is herein provided a
