ROLLER CLOTH CARBONIZER.

Application filed. September 27, 1922. serial No. 590,947

To all whom it may concern. 7

Be it known that we, EDGAR B. Knns'r and HERMANN BOGATY, citizens of the United States, residing, respectively, in Providence, Rhode Island, and Philadelphia, Pennsyl- Vania, have invented certain Improvements in Roller Cloth Carbonizers, of which the following is a specification.

Our invention relates to certain improvements in cloth carbonizers of the roller type, in which the cloth passes through a vat and then through a drier and carbonizer.

One object of our invention is to provide.

battles to protect the edge of the cloth the point where the air in circulation enters the drying chamber and the carbonizing chamber.

A further object of the invention is to provide means for spreading the cloth before it passes over the rollers.

The invention also relates to certain improvements in the apparatus as fully de scribed hereinafter.

In the accompanying drawings:

Fig. 1 is a side view of our improved roller cloth carbonizer;

Fig. 2 is a plan View;

Fig. 3 is a longitudinal sectional view;

Fig. 4 is a transverse sectional view on the line 44. Fig. 3;

Fig. 5 is sectional plan view on the line 5-5, Fig. 4;

Fig. 6 is a detached perspective view of one of the baffles;

Fig. 7 is an enlarged sectional view illus trating the Spreaders, and

Fig. 8 is a detached perspective view of one of the Spreaders.

Referring to the drawings, 1 is a vat through which the cloth a is passed. The cloth passes around rollers 2 in the vat and between rolls 3, 4 and 4, and around rolls 5, 5 to. a roll. 6 having its hearings on a frame 7 projecting from the casing of the drier 8. The cloth accumulates in the tray 9. The cloth then passes through a tension device 10 and over a roller 11 and enters the drying chamber 12, as shown in Fig. The casing encloses the drying chamber 12 and the carbonizing chamber 12, which is a continuation of the drying chamber.

Between the upper and lower rolls are spreaders 14 and 15. The spreaders 14 are curved and rounded, as shown in Figs. 7 and 8, so as to spread the cloth and remove wrinkles. The spreaders 15 are fiat and guide the cloth to the rolls. A pair of spreaders 14 and 15 is located in advance of each roll mounted on a vertical shaft 19 driven by a horizontal shaft 20. In the partition 21, which separates the heating chamber from the drying chamber, is a lower passage and an upper passage 23 for the air in circulation. shown by the arrows, Fig. 4.

To protect the edge of the cloth from damage due to the velocity of the air at the upper passage 28 where the air enters the drying chamber, baiiles 24 are provided, which enclose the edge of the cloth as clearly shown in Figs. 4 and 5. Each baffle is preferably made as shown in Fig. 6, of a sheet metal plate bent into form. The upper and lower edges of the battles are preferably flared, as shown, to provide smooth surfaces for the cloth. The baffles may be of any width desired.

When the cloth a leaves the drying chamber, it passes bet-ween rolls 25 and returns over the top of the drier, as clearly shown in Figs. 1 and 3, being supported by cross sticks 26 attached to stringers 27 secured to the ceiling 28 of the room. The cloth then enters the folding mechanism 29 of the usual eonstruotion.

In the vat 1 is a transverse partition 30 and comn'iunicating with the space 31 on one side of the partition is a vacuum pump 32. The shaft 38 of the pump is driven from a motor 34, which also drives the shaft 20 that is geared to the fan shafts.

is a variable speed gear through which the mechanism for imparting movement to the cloth is driven. The drive is shown in Figs. 1. 2 and 3.

Vie claim:

1. The combination of a casing enclosing a drying chamber; a heating chamber connected to the drying chamber by passages; means for circulating air in the chambers and through the passages; and battles arranged in. the drying chamber at one of said passages to protect the edges of the cloth passing through the drying chamber from The air circulates in the direction the action of air passing into the drying the other, said baflles protecting the edge of and carbonizing chambers.

the cloth from the action of the air in circulation.

3. The combination in a cloth carbonizer of the roller type, of a casing enclosing a drying chamber and a carbonizing chamber; a heating chamber at one side of said chambers and connected thereto; a circulating fan in the heating chamber; a series of upper rolls and a series of lower rolls in the heating and carbonizing chambers; and a series of vertically arranged baflles for protecting the edge of the cloth, said bafiles being V-shaped and located at the point Where air in circulation enters the drying 4. The combination in a cloth carbonizer of the roller type, of a casing enclosing a drying chamber and a carbonizin chamber; means for circulating heated air in sa-id'chambers; a series of upper cloth rolls and a series of lower cloth rolls in the drying and carbonizing chambers; and spreaders in advance of each roll for s reading the cloth before it passes around the rolls.

5. The combination in a cloth carbonizer of the roller type, of a casing enclosing a drying chamber and a carbonizing chamber; upper and lower rolls in said chambers around which the cloth passes; and two Spreaders in advance of each roll, one spreader being curved and rounded and the other being flat to spread and guide the cloth to the rolls.

6. The combination in a cloth carbonizer, of a vat; a pump therefor; guides in the vat for the cloth; squeeze rolls for the cloth; a drying chamber, a carbonizin chamber; rolls in said chambers over whic 1 the cloth passes in its passage through said chambers; means for feeding the cloth from the vat to the drier; means for carrying the cloth back over the carbonizer, drier and vat after it has passed through the carbonizer; and means for driving the pump and feeding means.
