Specification of Letters Patent.

Application filed March 9, 1917. Serial No. 153,560.

To all whom it may concern:

Be it known that I, LEE SUMNER Trroarr- SON, a citizen of the United States, residing in the borough of Brooklyn, city of New York, county of Kings, and State of New York, have invented new and useful Tmprovements in Machines for Dyeing Hanks ratus, the cover being shown raised in dotted lines;

Fig. 2 is an end view thereof;

Fig. 3 is an enlarged fragmentary view of one of the wheel spokes and a portion of a supporting ribbon secured thereto;

Fig. 4: is a section on the line M of Fig. 3;

Fig. 5 is a face view of a portion of a single ribbon;

Fig. 6 is a face view of a portion of a composite ribbon;

Fig. 7 is a longitudinal section through a portion of such composite ribbon;

Fig. 8 is a face view of the other member of this ribbon;

Fig. 9 is an enlarged semi-diagrammatic view of one of the wheels with ribbons thereon in concentric circles;

Fig. 10 is a similar view of a wheel with the ribbons arranged in spirals; and

Fig. 11 is a semi-diagrammatic view showing a way of supporting hat bodies or the like.

A pair of upright wheels 2 and 2 which in practice may be about six feet in diam eter, are mounted upon a driven axle 3 with their lower portions inside a vat 4:. The spokes 5 and rims 6 should be of some material, for example brass, having suitable strength and resistant to chemicals and steam, while the hubs 7 and the axle which are above the liquid level may be of iron. The material to be dyed is supported upon and between these Wheels, and, in order to accommodate hanks of different sizes or cloth of various widths, provision is made for changing the distance between them. To this end the axle is formed with a keyway 8 accommodating akey 9 in the hub of the wheel 2, so that this wheel may he slid along the shaft and set at any desired point by means of a screw 10. The other wheel preferably occupies a fixed position. The axle turns in bearings 11 upon standards 12 at opposite sides of the tub, running down to a firm foundation. The axle bears two sets of pulleys, one being a low speed drive pulley l3 and a corresponding idler 14:, and the other a high speed drive pulley 15 and corresponding idler 16. I

The means whereby the material is supported between the wheels-comprises flexible metal ribbons 17 or 17, of brass or the like, which are carried at the inner sides of the wheels encircling the axle at various distances therefrom, their arrangement being similar upon the two wheels.

. The mountings for these ribbons preferably comprise right-angular hook bolts 18, the shanks of which are screwed into threaded openings in the spokes and locked by nuts 19, the hook ends 20 being turned outward away from the axle and substantially parallel with the planes of the wheels. The ribbons are formed with openings 21 at intervals, which take over these hook ends. WVing nuts 22 have screw-threaded enga ement with the said ends for holding the ribbons firmly in place.

The single ribbons 17 are designed more particularly for thodyeing of hanks,through the ends of which the ribbons are passed, as indicated schematically in 1* i2. 2. When the single ribbons are used the are preferably disposed in concentric circles, as shown in Fig. 9, and it will be understood that each circle mav be composed of a number of sec tions overlapped at their ends. This is indicated in connection with the outermost ribbon of Fig. 9.

For dyeing cloth a double ribbon is employed, of which the members 17 and 17 have openings 21 as before; and in addition the member 17 is provided with pins 23 and the ribbon 17 with corresponding apertures 24. The marginal portions of the clothare impaled upon the said pins, held against slipping off them by the ribbon 17, and the composite structure is held together and secured in place upon the wheel by means of the hooks and wing nuts 18 and 22 just described. For cloth dyeing this form of ribbon is preferably arranged spirally about the wheel axle, as shown in Fig. 10, and, as before, the ribbon may be divided lengthwiseinto sections of convenient length.

In order to adapt the wheels for either style and arrangement of ribbon, it is desirable to provide their spokes with screwthreaded openings for the shanks of the hook bolts lying both in concentric circles and in a spiral.

An arched cover 26, hinged at 27 at one end, fits over the vat to keep heat, when drying, and steam, when dyeing, from escaping. This cover has an outlet 28 in the top to allow steam and moist hot air to escape to the exhaust pipe 29, and is also provided with a lateral openino 30 to admit hot dry air led from a suitable source through piping 31 to the space above the liquid in the vat. Connection is established between said entrance. and outlet and the corresponding pipe by means of sliding members 32 and 33, which can be readily slipped out of the way to permit the cover to be raised.

A pipe 3st for the supply of water or chemicals discharges into the upper part of the vat; and steam piping enters at the top, descends within the vat, and extends with perforations over the bottom substantially throughout the length of the vat to secure even boiling. The top is also provided with a direct connection 36 to the sewer, with a suitable plug 37 for opening and closing the same.

After the wheels have been loaded and the liquid introduced into the vat, the machine is set in motion by shifting the low speed band onto the low speed pulley, a speed in the neighborhood of ten revolutions per minute being preferred for dyeing. \Vhen the dyeing is finished the liquid is run off, fresh water admitted, and the material rinsed by revolving the wheels therein; then the water is allowed to escape, and the machine is thrown into high speed, causing it to act as a centrifu al extractor. At the same time hot air is blown directly on the stock, thus hastening the drying. For drying a speed of one hundred revolutions per minute is desirable.

Vhile a pair of wheels is spoken of, it will be understood that the capacity of the machine may be increased by placing another adjustable wheel on the other side of the fixed wheel, the inclosure being correspondingly increased in width.

For dyeing hat bodies or other articles, demountable bridges 38 may be carried from wheel to wheel or from ribbon to ribbon and suitably secured, and the objects attached thereto by hooks, or otherwise, as diagrammatically represented in Fig. 11.

That I claim as new is:

v 1. A dyeing and dryin machine comprising a vat, a pair of wheels therein upon a rotatable axle, and means for supporting the material on and between the wheels comprising curved ribbons mounted at the inner sides of the wheels.

2. In a dyeing and drying machine, the combination of a pair of wheels upon a rotatable axle, and means for supporting the material on and between the wheels comprising curved ribbons encircling the axle at different distances therefrom at the inner sides of the wheels, and hooks on the wheel spokes wherewith the ribbons are engaged.

3. A dyeing and drying machine, comprising a vat, a pair of wheels there-in upon a rotatable axle, means whereby relative adjustment may be produced between the wheels lengthwise of the axle, and means for supporting the material on and between the wheels comprising curved ribbons mounted at the inner sides of the wheels.

4. In a dyeing and drying apparatus, the combination of a pair of connected wheels, and means for supporting the material on and between the wheels comprising double ribbons, of which one member is provided with pins and the other with corresponding openings, and means for mounting the ribbons at the inner sides of the wheels.

Dated this 1st day of March, 1917.
