Improvements in Handles for Heated Objects.
I, WILLIAM HENRY BECK, of 115 Cannon Street, in the City of London,
Consulting Engineer and Chartered Patent Agent, 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, that is to say :-
Fig. 1 of the drawings is a central longitudinal section of the handle.
Fig. 2 is a plan view of the spiral coil of wire with its axial line extended in a
straight line and the ends of the wire bent at right angles to the axial line so as to
extend beyond the periphery of the coil.
Fig. 3 is a plan view of the outer end of a valve-handle having a portion of the
rim broken away to show the peripheral groove and sockets containing the bent
ends of the wire coil seated in such groove.
The invention relates more particularly to rotary handles employed in
connection with artificially heated objects such as stoves and steam-valves; and
consists in providing a knob or circular head with a peripheral groove having
sockets in the groove-wall adapted to receive the ends of a wire, and inclosing the
knob or head with a wire coil bent around the same and secured in the peripheral
groove by inserting the ends of the coil in the sockets in the groove-wall.
The object of the invention is to provide a handle for artificially heated objects
that will freely and rapidly radiate the heat conducted thereto from the heated
object, and also afford a convenient means for facilitating the grasp upon the
handle and preventing the haud from slipping thereon, when in use.
The radiating property of wire coils is well known and numerous forms, of
handles have been used in connection with heated objects in which the portion
grasped by the hand comprised coiled wire.
By providing the head of the handle with a peripheral groove and inclosing the
head with a coil of wire inserted and fastened in the groove, not only are all the
advantages of rapid radiation of heat secured, but the planes formed by the
individual coils or turns of wire being approximately radial to the axis of rotation
the coils offer much greater resistance to any slipping movement of the hand than
the smooth surfaces heretofore in use.
Referring to the drawings, A is the head of a knob or handle provided with a
peripheral groove A¹ and a socket A³ in the wall of the groove.
B is a wire coil which incloses the head, being seated in the peripheral groove.
The coil is held in place within the groove by inserting the ends, one only B¹ being
shown in Fig. 1, within the socket.
The head is provided with a screw-threaded attaching shank B' and nut B³ by
which it can be secured to certain objects, as for example to a stove door.
In Fig. 3 is shown the usual form of handle used in connection with steam
valves, a portion of the head-rim C being broken away to show the peripheral
groove formed therein, and both ends D, D of the coil D' inserted in their
respective securing sockets in the rim or groove wall.
The sockets may extend down through the rim proper into one of the spokes D'
as shown, to make the fastening more secure.
In putting on the wire-coil, it is only necessary to insert the two bent ends of the
coil in their sockets and then spring or stretch the coil sufficiently to force it over
one of the edge-walls of the peripheral groove into the groove, the coil being made

page_text: of the proper length so that the resilient force of the coil will draw it down firmly
into the groove and hold it there.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, as communicated to
me by my foreign correspondent, I declare that what I claim as new is :-
1. In a knob or handle, the combination with a peripherally-grooved head, of a
head-inclosing wire coil seated in the peripheral groove of the head, substantially
.as described.
2. In a knob or handle, the combination with a head having a peripheral groove
and sockets in the wall of such groove, of a head-inclosing wire coil seated in such
groove and having the ends of the wire bent and inserted in the sockets in the
groove-wall, substantially as described.
3. As a new article of manufacture, a knob comprising a peripherally-grooved
head, a head-inclosing wire coil seated in the head-groove, and an attaching-shank,
substantially as described.
