WIBE-ANNEALING FURNACE.

Specification of Letters Patent. Patented J 18, 1918 Application filed November 2, 1917. Serial No. 199,999.

To all whom it may concern:

Be it known that I, JOHN Coon ST. CLAIR, a citizen of the United States, residing at 'Johnstown, in the county of Cambria and State of Pennsylvania, have invented a Wire-Annealing Furnace, of which the following is a specification.

Figure 1 is a side elevation. front elevation. Fig. 3 is side elevation with outer brick wall removed. Fig. 4 is rear elevation. Fig. 5 is a view in elevation of one of the sheaves as herein embodied.

1-1 are cooling doors to be used in regulating temperature of the heat chamber 5.

2-2 are doors of fire boxes 9'9. 3'3 are doors to admit arms 6 upon which are sheave wheels 7, around which the wire is wrapped, the number of wraps determines the extent of annealation.

Arms 6 are drawn singly from the furnace to allow wire to be wrapped around sheaves 7, after which sheaves and arms are returned to furnace.

The wire continues from sheaves through holes in perforated plate 4, and is drawn from furnace by machinery working independently of furnace.

10 is rod upon which are secured jointed arms 6. 11 is a solid brick wall between fire com artment 8 and heat chamber 5. 12 is a bric or metal arrangement upon which rests arms 6 and keeps sheaves 7 slightly elevated above floor of heat chamber 5.

13 is draft route leading from fire compartment to under-ground flue.

I might add the following information concerning my invention:

While my drawing shows thirty arms and sheaves, this particular number does not in any way enter into the ideas embodied in my invention. The number of arms and sheaves may be more or less than shown in my drawmg.

The arms holding the sheaves are so arranged that they can be drawn singly from the furnace, the wire is then wrapped around the sheaves, the number of wraps will determine theextent of annealation;

for instance, a strand of wire given ten wraps around a sheave will not be annealed to the same degree of softness as a strand of wire given twenty wraps, for the reason that the strand of wire given twenty wraps will remain in the furnace twice as long as the strand given ten wraps.

I will also add that a particular size of Fig. 2 is furnace, or in fact, a particular size of any part of the furnace does not enter into the ideas embodied in my invention.

I am aware that prior to my invention the lead-pan method of annealing wire was used, but this being entirely different from my invention, I claim:

1.. In a wire. annealing furnace having openings in one end, a series of sheaves supported on jointed arms adapted to be individually withdrawn or placed into'the furnace chamber through said openings, and perforations in line with said openings at the other end through which the wire is drawn from the furnace.
