6 Claims. (01. 16—117)
My invention relates to handwheels for valves the handwheel and the valve stem, the opening

and has for its principal object to provide a
handwheel which may be ?rmly and comfortably
gripped and which will not slip from the grasp
in the hub preferably increases in cross sectional
area toward its lower end so as to have wedging
of an operator.
valve stem which decreases in cross sectional'area Cl
A primary feature of the invention consists
in providing the rim of the handwheel with a
toward its upper end.
plurality of ring-like members spaced longitudi
nally of the axis of the wheel, the ring-like mem
bers having correspondingly located indentations
in their peripheries and being connected by ribs
located adjacent the central portions of the in
dentations and at points intermediate the in
dentations.
Another feature of the invention consists in
providing the handwheel with a plurality of al
ternately reversely curved ribs connecting the
ring-like members of the rim which are of un
equal diameter and are spaced longitudinally of
the axis of the wheel.
'
A further feature of the invention consists in
providing the rim of the wheel with two sub—
stantially concentric ring-like members spaced
engagement with the squared portion of the

"
The rim 2 is provided with two substantially
concentric upper and lower ring-like members
‘I and 8, respectively, which are spaced from each
other in the direction of the axis of the wheel. 10
The upper ring-like member ‘I is of smaller di
ameter than the lower ring-like member 8 and
each is preferably composed of a plurality of
correspondingly disposed concave segments 9 so
as to provide the periphery of the rim with inden 15
tations.
The ring-like members are integrally connected
by a plurality of ribs III which are respectively
located adjacent the extremities of the concave
segments and they are also connected by a plu- -
rality of ribs l l respectively located adjacent the
central portions of‘ the segments. As the ex
tremities of the concave segments of each ring
longitudinally of the axis of the wheel, the ring
like members respectively consisting of a plu
rality of correspondingly disposed concave seg
like member are disposed a greater distance from
the axis of the handwheel than the central por
ments which are connected adjacent their ex
tremities by convex ribs and adjacent their cen
tral portions by concave ribs.
Other and more speci?c features of the in
3O
ribs ID are spaced a greater distance from the
vention, residing in advantageous forms, combi
nations and relations of parts, will hereinafter
appear and be pointed out in the claims.
In the drawing, illustrating a preferred em
bodiment of the invention,
Figure 1 is a perspective view of the handwheel.
Figure 2 is a plan view of the handwheel.
Figure 3 is a view showing the handwheel
mounted on a valve stem, the wheel being partly
40 in section and partly in elevation.
Figure 4 is a sectional view taken on line 4—4
of Figure 2.
Figure 5 is a sectional view taken on line 5—5
of Figure 3.
Referring more particularly to the drawing,
the handwheel comprises generally a hub l, a
rim 2 and arms 3 connecting the hub and rim.
The hub is provided with a square opening 4
for receiving the reduced upper end of a valve
stem 5 which, although being square for the
major part of its length to conform to the open
ing in the hub, terminates in a cylindrical screw
threaded portion for receiving a nut 6 by which
the handwheel is ?rmly connected to the valve
55 stem. To effect a very rigid connection between
tions of the segments, it will be perceived that
axis than ribs II and they, therefore, afford
abutments against which the ?ngers of an op
erator may bear in rotating the wheel.
Although ribs Ill and H may be straight, it is
preferred, in order to increase the effectiveness
of ribs ID as abutments, to- makev the latter ribs
convex and the ribs ll concave.
This results in
materially increasing the effective depth of the
indentations in the periphery of the rim and
enables such an exceedingly ?rm grip to be ob
tained upon the Wheel that, even though the hand
of the operator be wet, it will not slip. In ad
dition to providing means for obtaining greater
driving power, the convex ribs l0 materially in
crease the strength of the handwheel without
substantially increasing its weight.
By spacing the ring-like members longitudi
nally of the axis of the wheel and connecting
them with ribs, it will be evident that heat trans
mitted from the hub to the rim will be rapidly
dissipated and that, without substantially in
creasing its weight, the wheel may be made of
such height as to provide su?iciently large con
tact areas for the ?ngers of an operator that it
may be ?rmly gripped without discomfort. The
force exerted by the operator need not, therefore,
be restricted to the power obtained by the ends
of the ?ngers, as is the case in operating wheels 55

‘of low height and, since it is possible for the
?ngers of the operator to nest comfortably with
in the depressions, greater purchasing power is
obtainable with less effort.
The increased height of the wheel also enables
the hub to be offset su?iciently below the top of
the rimwithout impairing the strength of the
wheel that the upper end of the valve stem as
Well as the securing nut 6 will be disposed below,
10 a plane passing through the top of the rim. This
is particularly advantageous when the handwheel
is used with valves for controlling steam or other
hot ?uids, because it enables an operator to
grasp the wheel with his palm overlappingly en
gaging the outer end thereof without danger of
being burned by heat radiated through the valve
stem.

1. A handwheel for valves and the like in
cluding a hub portion, and a rim connected to
the hub, said rim having a'plurality of'ring-like

ring-like members being provided with indenta
