F will maintain an accurate position at all
times, so that when the disk A is turned in
the direction indicated by the arrow (see Fig.
5) the several grips will in unison engage the
5 shaft, and thereby avoid the twisting strain
incident to the use of clutch members which
must be held up by spiral or other spring
pressure, as in the use of such clutch devices
the tension of the several springs soon be-
1o comes unequal and thereby causes the sev-
eral grips to irregularly grip the shaft and give
it atwist strain. Furthermore, as the grips F
when in the position shown in Fig. 4 are prac-
tically loosely held between the shaft and the
15 base of the pockets it is manifest that when
the disk A turns in the direction indicated
by the arrow in such Fig. 4 and the shaft
turns in the opposite direction the said disks
F will also rotate and thereby reduce the fric-
20 tional bearing of the shaft on such disks to
a minimum.
When a double set of clutch devices are
used, metallic washers g are placed between
them to hold the grip members in place.
25 K indicates a frame slotted at k c to fit over
the drive-shaft, which frame is in practice
adapted to be reciprocated in any desired
manner, and such frame has oppositely-dis-
posed rack portions kc2 k2, which are held in
30 engagement with toothed wheels secured to
or formed integral with the disks A A, as
shown, it being manifest, however, that in
practice the reciprocating devices can be va-
ried as may be desired.
35 While I prefer to use the clutch mechanism
as a double clutch it is manifest but a singleset need be employed, the intermittent opera-
tion of which will serve to impart a rotary mo-
tion to the shaft, it being obvious that such
devices may also be used in the nature of a
grip for engaging and lifting a non-rotatable
shaft.
In Fig. S I have shown a somewhat modi-
fied form of the device which is especially
adapted for use for heavy machinery. In this
construction a sleeve or hub portion M is fix-
edly connected to the shaft with which the
grip members engage, such portion taking up
the wear produced by the clutching action of
the grips.
Having thus described my invention, what
I claim, and desire to secure by Letters Pat-
ent, is-
As the improvement hereinbefore specified,
the combination, with the drive-shaft, and a
clutch-disk having an axial opening which
considerably exceeds the diameter of said
shaft, and provided with a recess, a, whose
periphery is a series of eccentric portions, C,
connected by radial shoulders, and a like se-
ries of circular disks which are distributed in
the eccentric pockets and wholly independent
of each other, and whose diameter consider-
ably exceeds the distance between the radial
opening and the farthest radial point of any
of said eccentric portions, as shown and de-
scribed.
