O U FALO, NEW YORK- VACUUMI DRYING APPARATUS.
Application filed November 23, 1908.
To all whom it may concern.-
Be it known that 1, EMIL WILHELM STROHN, a subject of the German Em veror, residing at Buffalo, in the county of Erie and State of New York, have invented a new and useful Improvement in Vacuum Drying- Apparatus, of which the following 1s a specification.
This invention relates to an apparatus for removing moisture and volatile ingredients under a vacuum from fabrics, belts, cables, cords and other mateiials which are manu factored in webs or considerable lengths and are wound upon drums or reels.
The apparatus comprises, briefly stated, an air-tight casing which communicates with an exhaust mechanism and is otherwise closed, heating chambers arranged in said casing at suitable distances a art so that the web of material can-travel ack and forth between. these chambers, propelling rolls which arearrang'ed within the casing and draw the material through the apparatus, and a drum or reel upon which the finished material'is wound and which is also arranged within the casing.
In the accom anying drawings, consisting of four sheets: igure 1 is a side elevation of my im roved drying apparatus. Fig. 2 is a vertica longitudinal section of the same, in line 22, Fig. 4. Fig. 3 is a vertical transverse section in line 3-3, Fig. 2. Fig. 4 is a top plan view. Fig. 5 is a fragmentary longitudinal section showing a modified construction of the front portion of the apparatus. .Fig. 6 is a fragmentary longitudinal section of the rear portion oi the apparatus, illustrating a modified construction thereof. Fig. 7 is a fragmentary horizontal section in line 77, Fig. 6.
Like reference characters refer to like parts in the several figures.
Referring to Figs. 14, Arepresents the body of the air-tight casing provided at its front end with a door 20 for the introduction of the web, fabric crother material tobe treated and having at the o posite or rear end a door 21 for the remova of the treated roll of material. These doors are balanced by counterweights 22, 23, so that they can be conveniently applied and removed. The body of the casing is provided with a raised top portion or donle 24 which is provided with an exit opening 25 by which the apparatus communicates with a suitable vacuum Specification of Letters Patent.

! or exhaust and condensing apparatus. This i dome is provided with a removable cover 26 l for giving access to the interior.
' B represents the heating chambers or sections which are arranged vertically in the middle portion of the apparatus and which extend into the dome thereof. These chambers are preferably flat-sided boxes arranged i transversely in the apparatus and receive 1 steam from a manifold head 27 through individual pipes 28 and discharge the condensed water through individual pipes 29 and a manifold head 30.
31 represents guide rolls, arranged in the dome above the heating sections, and 32 represents guide rolls arranged below the sections in such manner that the web C of material is directed upwardly on one side of each section and downwardly on the opposite side.
33 represents the drum or reel which contains the web to be treated and is arranged within the front portion of the casing. 'ihe web passes from this reel downwardly to the first lower guide roll 32, thence upwardlyand around the first upper roll 31, thence downwardly to the second lower roll 32, and so on until it has passed around the last lower roll 32 from which the web passes to a pair of propelling rolls 34. These propelling rolls are driven by any suitable mechanism, for instance, as shown, by a train of gear wheels 35, 36, 37 and 38, the two rolls 34 being connected by gear wheels 39. Pressure is applied to these rolls by springs 40 or other means for gripping the web, unwinding the same from. the reel 33, and propelling the same through the apparatus. A hand brake 41, 42 is preferably applied to this reel for controlling its unwinding movement.
43 represents the receiving reel upon which the treated web is wound and which is ar, ranged within the rear portion of the casing. This reel receives the web C from the propelling rolls 34 and may be driven by any suitable mechanism, forinstance, as shown, by a belt 44 running around pulleys 45, 46.
l'Vhe-n this apparatus is used for drying material which has been impregnated with a stickysubstance, for instance, an insulating composition, it is desirable to keep the sticky layers or convolutionson the receiving reel separate, and for that purpose a web D of dry material is wound upon the receiving reel simultaneously with the web of impregnated material. The web D is unwound from an auxiliary reel 47 which is preferably provided with a band brake 48, 49.
Inv the operation of this apparatus the reel containing the Web to be treated is introduced into the front portion of the apparatus and the web is passed around the series of guide rollers and between. the propelling rolls and attached with its end to the receiving reel in the rear portion of the apparatus. The casing is then closed and exhausted and the web is slowly passed from the unwinding reel to the receiving reel. During its passage from one reel to the other the material is exposed to the heat given oil" by the heating chambers, while under a more or less perfect Vacuum, whereby ;z;oisture or volatile in atter contained in the web of material is thoroughly removed. This apparatus may be used for drying fabrics before impregnating them with insulating or other liquids or for drying the fabric after it has been so irrzpregnated. In the latter case the volatile ingredients of the insulating composition are removed and recovered during the drying operation. The donze containing the upper portions of the heating chambers concentra'tes the heat upon the upper portions of the convolutions ol' the web and causes a thorough heating of the web at the point where the exhaust is most directly applied. When the web to be treated is folded, as rep.- resented in- Fig. 5, instead of being wound upon a drum or reel, the front portion of the casing is provided with a air of guide rolls 50, between which the we l) passes in being unfolded and in passing to the first lower guide roll. When the apparatus is used for treating material which is not sticky and does not require the employment of a separating web 1), as in drying material preparatory to impregnating the same, the rear portion of the apparatus can be reduced in height, as represented in Fig. 6. The sides of the casing are preferably provided with transparent plates 51, 52, for illuminating the interior of the apparatus and observing its operation.
I claim as my invention:
1. The combination with a hermeticallyclosed casing adapted to be exhausted, of heating chambers arranged within said 0815-.
. ing and separated by intervening spaces,
guide rolls arranged at opposite ends of said heating chambers, propelling rolls arranged in rear of said heating chambers and adapted to draw the web of material to be treated around said guide rolls and past said heating chambers, and a receiving reel arranged within said casing in rear of said propelling rolls, substantially as set forth.
2. The coi'nbination with a hermeticallyclosed casing adapted to be exhausted, of heating chambers arranged within said casing and separated by intervening spaces, guide rolls arranged at o posite ends of said heating chambers, prope ling rolls arranged in rear of said heating chambers and adapted to drawthe web of material to be treated around said guide rolls and past said heating chambers, a receiving reel arranged within said casing in rear of said propelling rolls, and an auxiliary reel arranged in the rear portion of said casing for supplying a separating web to the receiving reel, substantiallyas 'set forth.
3.
