DRYING Maonmn.

Application filed September 29, 1925. Serial No. 59.434.

This invention relates to a new and improved drying machine, and more specifically to a machine for drying a tubular fabric. I The object of this invention is the production ot a machine for drying a tubular fabric in an eiiicient and economical way and in such a uniform manner as to avoid the production of streaks in the fabric which render it unmerchantable.

Other objects and advantages relate to the details of the structure and the form and relation of the parts thereof, all as will more fully appear from the following description, taken in connection-with the accompanying drawings, in which Figure 1 is a top plan view of a portion of the apparatus.

Figure 2 is an enlarged sectional view on line 22, Fig. 1.

Figure 3 is an elevation of a portion of the structure.

Figure a is an elevation partially in section of a special type of spreader mechanism. V

The apparatus as here illustrated comprises a base 1 supported in any suitable manner, as by legs 2 andhaving a flanged opening 3 at its central portion for the reception of a hot air pipe l'connected as shown to a blower 5 or' other source of air under pressure. Means should be provided for heating the'air supplied to the pipe 4: and for that purpose there is shown in Figure 1 in dotted lines a series of steam coils (S altho any other suitable means or arrangeiuent for heating the air may be provided. The pipe 4 preferably includes adamper 7 which may be actuated as desiredto control the flow of the heated air therethrough.

The base 1' carries an annular disk 8 having an opening at its center surrounded by thetlann'c 9 around which a vertically disposed tube 10 of sheet metal or similar material is telescoped concentric with the tube i0 and outside the latter .is arranged a cylinder i'l so as to form between the tube 10 and. the cylinder an air chamber or space 12 closed at its lower end by the disk 8 and at its upper end by the depending side of the annular angle bar 13 the other side of the angle bar 13 extending radially outwardly beyond the cylinder 11 and across the upper end of the spacing member l twhich closes the upper end of an annular water jacket 15 formed between the cylinder 11 and a second cylinder 21 of somewhat larger di ameter and surround ng the cylinder 11 The lower end of this water jacket is closed by an annular spacing bar 16. The 69 to any suitable source of water under pres- 55 sure, as a pump, and preferably pipe 17 sup plies the cooling fluid to the lower end of the water jacket 15 and pipe 18 connected to the upper end of the water jacket 15 and extending downwardly when tube 10 re- Z0 turns the cooling fluid to the pump (not shown). The tube 10 as illustrated, extends some distance above the annular angle bar 13 and is equipped with a reenforcing cylinder 19 secured to the tube 10 in. any suitable manner, as by bolts or rivets 20. This cylinder,-as shown, is of somewhat less diameter than the cylinder 21 so that the fabric as it moves oil the cylinder 21 and onto the spreader mechanism 22 does not come in contact with the cylinder 19.

The spreader mechanism 22 comprises a vertically disposed shaft 23 having its lower end seated in a hearing or recess 2% formed in bar 25 extending diametrically across the upper end of the cylinder 19, and as shown, formed integrally therewith. tdet screw 26 or other means may be provided for securing theshaft in the bearing. The spider mechanism comprises in addition to the shaft 23 a series of

rollers

27 and 28 respectively. These rollers may be mounted in any suitable manner and as shown, the shaft 23 is provided with a collar 29 for each pair of rollers, and this collar carries two parallel bars 30 disposed upon opposite sides o1 the Shaft and at their ends these bars carry shafts 31 upon which the

rollers

27 and, 28 respectively are mounted; The length of the bars 30 may vary throughout the spreader mechanism, or may be uniform desired. As shown. the lower series of bars are of substantially uniform length and the

respective rollers

27 and 28 are alternately arranged-this 'iarticular illustration show ing four sets 27 arranged in one direction and four sets 28 arranged at right angles to sets 27. l

In addition, at the upper end of the shaft 23 there'are two sets of rollers 28 arranged adjacent each other and adapted to act to somewhatflat-ten out the fabric which has rolls and around the take-up roll 35.

been maintained in substantially tubular form by the alternate sets of

rollers

27 and 28 so that when the fabric is supplied to the spreader bar 31 it will be in a position to substantially conform to the spreader bar, and will readily pass between the guide bars 32, between the

pressure rollers

33 and 3 for winding in substantially cylindrical form upon the take-up roller 35 which may be driven in any suitable manner, and at any suitable speed not necessary to herein further illustrate or describe.

The base 1 also supports a. cylindrical receptacle or tub surrounding the water jacket 1.5 and of considerably greater diameter than the cylinder 21 and the bottom of this tub may be formed of wood or any suitable material, while the cylindrical wall may be formed of sheet metal or any other suitable material and the fabric in tubular form and in damp condition where drying is required is first fitted over the cylinder 19, and allowed to pass down around the water jacket 15 and accumulates in the receptacle 36.

The spreader mechanism 22 is then placed in position, the upper end of the tubular fabric is drawn up around the neck of the spreader mechanism between the pressure The hot air may then be turned on by opening damper 7, pump supplying water to pipe 17, and in like manner the means for driving the roll 35 is placed in operation, and as the fabric is drawn up around the spreader mechanism 22 the heated air escaping from the upper end of tube 10 comes up within the tubular fabric and escapes outwardly through the pores thereof, and thereby dries the fabric. Meanwhile, the fabric surrounding the cylinder 21 is maintained in cool condition and is not dried while in contact with the cylinder 21, which would result in the formation of streaks, but is only dried after it is moved out of contact with the cylinder 21, and is in a position to permit the free escape of the hot air through the pores of the fabric as the latter is spread out and maintained in tubular form by the

rolls

27 and 28 over which the fabric moves.

It is found that by this machine, the drying of tubular fabrics can be effected in such a uniform and efficient manner as to eliminate streaks and produce merchantable fabric in an economical and rapid manner.

Altho I have shown and described special constructions as illustrative of perhaps preferred embodiments of the invention 1 do not desire to restrict myself to the details of form, construction or arrangement, or to all of the perhaps preferred features of the invention, as various changes, modifications and omissions may be made within the scope of the appended claims.

I claim:

1. A drying machine for tubular fabric comprising a tube along the exterior of which the fabric is adapted to be drawn, an air chamber surrounding the tube, a water jacket surrounding the air chamber, means for supplying a drying fluid to one end of the tube, and a spreader mechanism at the opposite end of the tube over which the fabric is adapted to be drawn and which permits the drying fluid to contact with and escape through the fabric.

2. A drying machine for tubular fabric comprising a tube along the exterior of which the fabric is adapted to be drawn, an air chamber surrounding the tube, a water jacket surrounding the air chamber, means for supplying a drying fluid to one end of the tube, and a spreader mechanism comprising a plurality of rollers at the opposite end of the tube over which the fabric is adapted to be drawn and which permits the drying fluid to contact with and escape through the fabric.

8. A drying machine for tubular fabric romprising a tube. means for supplying a drying fluid to the tube, a bearing disposed substantially centrally at the upper end of the tube, a shaft having its lower end mounted in said bearing, a spreader-bar carried by the upper end of the shaft, a plurality of cross-bars mounted on the shaft in alignment with the spreader-bar, wheels carried by each crossbar atopposite sides of the shaft and rotating on axes at substantially right angles tothe spreader-bar, additional cross-bars mounted on the shaft below the first-named cross-bars and disposed at substantially right anglesto the first-named cross-bars and wheels mounted on the opposite ends of each cross-bar and rotating on axes substantially parallel with the spreader bar.

In witness whereof I have hereunto set my hand this 19 day of September, 1925.
