Improvements in Handles of the Hand Wheel Type.
I, NELSON HINDLEY PROUTY, residing in the Town of Charlton, in the County
of Worcester, in the State of Massachusetts, United States of America,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
My invention relates to handles of the handwheel type, and more particularly to
non-heat conducting handles, and to steam valve handles.
The object of my invention is to provide a handle, and more particularly a steam
valve handle, which will be substantially non-heat conducting, and will be of very
simple construction and inexpensive to make; and at the same time to retain the
ordinary circular shape of the handle, and allow of the firm grasping thereof with
the whole hand of the user, so that the hand will not slip on the periphery of the
handle, as is the case in ordinary steam valve handles.
My invention consists in certain novel features of construction of a handle, and
more particularly in combining with the circular end of the handle a spirally coiled
wire which is secured to the edge of the circular end forming the grasping surface
of the handle.
In my handle a circular disc or plate is secured upon the end of the stem of the
handle, and a spirally coiled wire is combined with the circular disc or plate, and
extends completely around and encircles the outer edge or periphery of the disc to
form the handle portion, or grasping surface.
The spirally coiled wire forming the grasping surface is preferably made in one
piece, and is secured to the circular disc portion of the handle by passing it through
holes or openings in the edge thereof.
The spiral coil formation of the grasping surface of the handle will enable the
user to hold the handle firmly, and prevent the hand from slipping thereon.
Dated this First day of February 1893.

Improvements in Handles of the Hand Wheel Type.
I, NELSON HINDLEY PROUTY, residing in the Town of Charlton, in the County
of Worcester, in the State of Massachusetts, United States of America,
Manufacturer, do hereby declare the nature of this invention, and in what manner
the same is to be performed, to be particularly described and ascertained, in and
by the following statement :-
My invention relates to handles of the handwheel type, and more particularly to
non-heat conducting handles, and to steam valve handles.
The object of my invention is to provide a handle, and more particularly a
steam valve handle, which will be substantially non heat conducting, and will be of

page_text: very simple construction and inexpensive to make; and at the same time to retain
the ordinary circular or wheel shape of the handle, and allow of the firm grasping
thereof with the whole hand of the user, so that the hand will not slip on the
periphery of the handle, as is the case in ordinary steam valve handles.
My invention consists in certain novel features of construction of a handle, and
more particularly in combining with the circular end of a handle a spirally coiled
wire, which is secured to the edge of the circular end, and forms the grasping
surface of the handle, as will be hereinafter fully described.
Referring to the drawings:-
Figure is an end view of my improved handle, looking in the direction of
arrow a, Fig. 2, and,
Figure 2 is a cross section, on line 2, 2, Fig. 1, looking in the direction of arrow b,
same figure.
I have shown in the drawings my improvement applied to a steam, valve
handle.
In the accompanying drawings, 1 is the stem of a steam valve handle provided
with a screw threaded end 2, and a collar 3, in the ordinary way. Upon the outer
end of the stem is secured, in this instance by a screw 4, a disk 5, which has a
central hole therein, into which the end of the stem 1 extends, and a series of
holes 6 in the outer edge thereof. A spirally coiled wire 7 is combined with the
disk 5, and extends completely around and encircles the outer edge or periphery of
the disk to form the handle portion. The wire 7 is preferably made in one piece,
of sufficient size and strength to prevent its bending or getting out of shape when
it is grasped and pressed in the hand, and is secured in the disk 5 by passing it
through holes 6 in the edge thereof, in the manner shown in the drawings. The
free ends of the wire may be soldered or secured in one of the holes 6, as shown at
the left in Fig. 2, so as to present a continuous spiral coil without a break or seam
to be grasped by the hand."
In case the handle is used as a steam valve handle, the heat of the steam passing
through the stem 1 to the disk 5, will pass off through the holes 6 in the disk, and
the free circulation of the air through said holes 6, which are larger than the
diameter of the wire 7, see Fig. 2, and through and between the coils of the wire 7,
will prevent said wire from becoming heated.
The spiral coil formation of the grasping surface of the handle will enable the
user to hold the handle firmly, and prevent the hand from slipping thereon.
I have described my improvement in handles in connection with steam valve
handles, but it may be used in connection with any other handles, if desired.
The advantages of my improved handle will be readily appreciated by those
skilled in the art. It is of very simple construction, very durable, and of pleasing
and attractive appearance to the eye, and it may be used in place of ordinary
bandles for different purposes, whether the same are required to be non-heat
conducting or not.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
As an improved article of manufacture, a handle, consisting of a disk, or circular
plate provided with holes or openings in the edge thereof, and a coiled wire
extending around the edge of said disk, and passing through the holes therein,
substantially as shown and described.
