Jan. 21, 1930,, D. P. MOORE KNITTED FILE FABRIC Filed July 25, 1928 gmnto'o Patented Jan. 21, 1930 PATENT OFFICE DAVID PELTON MOORE, OF AVON PARK, FLORIDA KNITTED PILE FABRIC Original application filed August 11, 1927, Serial No. 212,330. Divided and this application filed July 23, 1928. Serial No. 294,610.

This invention relates to improvements in knitted pile fabrics, one object of the invention being the provision of a knitted pile fabric in which the basic web, which may be a simple web, or base strands, are of Wire, pref erably solenoid wire, that is, metal strand or strands, covered with insulation, and the pile elements knitted in with the Wire strands or strand are short, loose or untwisted fibers, preferably of wool, the fabric being specially designed for electrically heated garments, blankets and warming units of-heated pads, the present application being-a division of my application filed August 11, 1927, Serial No. 212,330.

Another object of this invention is the provision of a pilefabric in which the solenoid wire constitutes the base yarn and is operated upon by a knitting machine, while the material forming the pile is fed into the same through the instrumentality of a machinev somewhat similar to that shown in the Tauber Patent No. 1,114,414 of October 20th, 1914, wherein the fibers with the proper tension of the base yarn are fed into the open eyes of the needles and the solenoid wire embedded therein during the knitting operation, so that the finished fabric is completed in the Tauber machine and the insulated wire is properly covered by the pile elements, so that an exceedingly durable and inexpensive heating unit is provided.

In the accompanying drawings is shown a perspective and'diagrammatic view of a piece of the fabric made according to and embody ing the present invention.

, Referring to thedrawings, the numeral 5 designates the solenoid Wire and 6 the pile elements. In the formation of the same the pile elements are fed into the openneedlesjust previous to the positioning of the solenoid wire 5 therein, the solenoid wire being tensioned so that when the needlemoves downwardly and the latch is closed the'wire is embedded within the loop portion 8 of the pile element-s and the rear surface is properly coated with the same.

As shown, these pile elements are tied into the loop 8 so that the loop portions of the pile elements will be securely tied in by the base wire.

*quired. That is for aviator suits or blankets only a slight heat. is necessary to produce a warm medium to holdin or retain the body heat, whereas when used as a heating pad a heavier voltage to produce real warmth is desirable. I

I claim c 1. A knitted pile fabric for electrically heated elements, comprising a base web having a wire strand, and pile elements composed of ghort loose fibers knitted in with the base we 2. A knitted pile fabric for electrically heated elements, comprising a basic Web having an insulated wire, and pile elements'composed of short'loose fibers knitted in with the insulated wire.

3. A knitted pile fabric for electrically heated elements, comprising knitted base strands of electrical conducting material, and heat retaining pile elements knitted in with the base strands.

4. A knitted pile fabric according to claim 3, in which the pile elements are short fibers loose and longitudinally disposed.

5. A knitted pile fabric, comprising knitted base strands of electrical conducting material, and heat retaining pile elements, said base strands being insulated wire and the pile elements being short loose wool fibers, the pile elements being knitted in with the insulated 6. A knitted pile fabric for electrically heated elements, composed of a basic web made Wholly or partially of insulated wire, and heat retaining pile elements knitted'in with the base web.

In testimony whereof I have hereunto set my hand.
