To all whom it may concern: in which that portion grasped by the hand Be it known that I, GEORGE J AOKSON, aciticomprised coiled wire. zen of the United States, residing at Cohoes, I have ascertained that by providing th county of Albany, and State of New York, head of the handle with a peripheral groove 55 have invented certain new and useful Imand inclosing the head with a coil of wireinprovements in Handles, of which the followserted and fastened in the groove, I not only ing is a specification. secure all the advantages of rapid radiation My invention relates to suchimprovements of heat, but the planes formed by the indiand consists of the novel construction and vidual coils or turns of wire being approxi- 6o [0 combination of parts hereinafter described mately radial to the axis of rotation, the inand subsequently claimed. dividual coils offer much greater resistance Reference may be had to the accompanyto any slipping movement of the hand than ing drawings, and the letters of reference the smooth surfaces heretofore in use. marked thereon, which form a part of this Referring to the drawings, A is the head 65 specification. of a knob or handle provided with a periph- Similar letters refer to similar parts in the eral groove A and a socket A in the wall several figures therein. of the groove.

1. In a knob or handle, the combination with a peripherally grooved head, of a headinolosing wire coil seated in the peripheral groove of the head, substantially as described.

5 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 headinelosing wire coil seated in such groove and having the ends of the wire bent and inserted 10 in the sockets in the groove-wall, substantially as described.

3. As a new article of manufactnre,a knob comprising a peripherally grooved head, a head-inclosing wire coil seated in the headgroove, and an attaching-shank, substantially I 5 as described.

In testimony whereof I have hereunto set my hand this 21st day of June, 1893.
