United States Patent 3,352,129 TEXTILE PROCESSING SEALER Frank J. Johnson, 505 Shoemaker Ave., Jenkintown, Pa. 19046 Filed Sept. 13, 1965, Ser. No. 486,877 3 Claims. (Cl. 685) This invention relates to improvements in textile and material processing machinery such as dryers, bleachers etc. and has special reference to prior mechanisms of the type where knitted goods, fabric, stock or other material is conveyed by feed aprons, feed rolls or other means into a chamber and where leakage of heat, air, steam etc. is prevented by a separate means such as water spray, bafile etc. and where separate rolls are required to create a pressure squeeze to the material.

The object of my invention is to provide a means by which the above operations can be performed with far less mechanism and fewer parts, thereby reducing manufacturing costs.

A further object of my invention is to provide a simple means of incorporating the aforementioned operations into a single compact unit, thereby reducing space requirements and maintenance overhead.

A further object is to provide a means of conveying and delivering material into and from the process machinery.

A further purpose is to provide a simple positive means of sealing such machinery from leakage.

A further purpose of this invention is to provide a simple means of accommodating various thicknesses of material.

A still further purpose is to provide a simple means of applying a desired pressure to the material as it is conveyed into the machinery.

The novel features that I consider characteristic of my invention are set forth with particularity in the appended claims.

The invention itself, however, both as to its organization and its method of operation, together with additional objects and advantages thereof, will best be understood from the following description of a specific embodiment, when read in connection with the accompanying drawing, in which like numerals refer to like parts in all figures.

The broader features of my invention are shown in FIGURE 1.

A chamber 13 may be any suitable material processing machine of the prior art, the illustration being intended for a conventional illustration of any type to which my invention is adapted.

I provide an assembled unit 1 for application to existing material processing machinery, preferably hinging the unit to the feed and delivery ends of the chamber in position to normally register a material conveying feed and delivery belt with feed and delivery openings of chamber.

The unit fastens in place in registry with the chamber by means of a suitable latch or readily loosened mechanism which permits easy access to the chamber feed or delivery opening.

FIGURE 1 is a side elevation, in section, illustrating a desirable form of mechanism embodying one form of my invention and showing a partial section of a material processing chamber 13.

FIGURE 2 is a horizontal section taken on line A-A of FIGURE 1, showing side plates 2 and 3 attached to main body and drive shafts 6 and 7.

FIGURE 3 is a horizontal section taken on line AA of FIGURE 1, with the components removed in order to better show the concave sealing surfaces 1.

3,352,129 Patented Nov. 14, 1967 FIGURE 4 is a vertical section taken on line B-B of FIGURE 1, showing attachment bolts and driving means.

1 is a main housing. 2 and 3 are side plates, which attach to main housing 1 allowing assembly of internal components and containing bearings 4 shown in FIG- URE 1.

Belts 5 have lengthened internal grooves and are rotated by contact with lengthened teeth on cogs 6, which are attached to shafts 7,8 and 9.

The lengthened teeth on cogs 6 permit contact with mating teeth of belts 5, as belts are separated or brought closer together when air pressure is induced through intake part a located in side plate 2, which also has exhaust port b and air pressure gage port 0, which allows control of pressure to internal surface of belts 5 contacting material entering housing 1 at opening d and entering chamber at opening e, FIGURE 1.

Balanced pressure at top of upper belt 5 and bottom of lower belt 5 prevents belts from contacting top and lower surfaces of housing 1 thereby reducing driving friction.

Increased application of pressure increases sealing effect on surfaces 7, FIGURE 3, which are restricted in area to decrease driving friction and wear on belts 5.

Drive shafts 8 and 9 FIGURE 4 have grooves for air seals 10 and have driving gears 11 with lengthened teeth mounted outside of side plate 2. Shaft 9 also has mounted to it sprocket 12 which affords external driving of belts 5. Lengthened teeth on gears 11 allow tooth contact when belts 5 are separated.

The operation of the textile processing sealer attached to a material drying machine is as follows:

Material is fed into entrance opening vof the sealer between the conveyor belts. The belts are internally pressurized to a predetermined air gage reading, creating the desired squeeze to the material, while simultaneously contacting the annular surfaces of the sealer.

Escaping heat, air or steam from the entrance opening of the dryer contacts the pliable belts of the sealer and is prevented from leaking past the belts to the upper and lower sections of the sealer housing.

Contact of the belts with the material prevents leakage between the belts. Thereby a perfect seal is established while the material is fed into the dryer. The conveyor belts are furnished with a suitable drive to 0perate.

The sealer functions in like manner to prevent leakage, when attached to delivery end of dryer except that the material feeds from the dryer into the sealer and the sealer belts operate in the reverse direction.

Although I have shown and described certain specific embodiments of my invention, I am fully aware that many modifications thereof are possible. My invention, therefore, is not to be restricted, except insofar as is necessitated by the prior art and by the spirit of the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent is:

1. In a processing sealer as described the combination of a housing to enclose mechanism, said housing having entrance and exit openings for unrestricted passage of materials, means for attaching said housing to any material processing machine, said housing having attached thereon side cover plates, said side cover plates provided with shaft bearings, two pair of shafts supported in said bearings, one pair of said shafts parallel to and above the other pair of said shafts, mounted on each end of said shafts an endless belt conveyor, the lower section of belt of said upper conveyor and the upper section of belt of lower conveyor adjacent to each other, means to drive said shafts and said conveyor belts, the said housing provided with two internal semi-annular concave projected sealing members, said sealing members located to contact each of said conveyor belts at position of fabric exit from said housing.

2. The combination in a textile processing sealer as described the combination of a housing to enclose mechanism, said housing having entrance and exit openings for unrestricted passage of materials, means for attaching said housing to any material processing machine, said housing having attached thereon side cover plates, said side cover plates provided with shaft bearings, two pair of shafts supported in said bearings, said shafts having cog members securely mounted thereon, one pair of said shafts parallel to and above the other pair of said shafts, mounted on each pair of said shafts, an endless belt conveyor, said belts have teeth on inside periphery, said teeth to engage with cogs on said shafts, the lower section of belt of said upper conveyor and the upper section of belt of said lower conveyor adjacent to each other, means to drive said shafts and said conveyor belts, means to admit pressurized air in said housing between belts of each of said conveyors producing a squeeze on fabric being fed between adjacent belts, the said housing has two internal projected semi-annular concave sealing members, located to contact each of said pair of conveyor belts at position of fabric exit from said housing.
