SPECIFICATION forming part of Lettere Patent No. 354.797, atea December 21,1886.

Application inea March es, Isae. serial No. 196,642. v(No model.)

, l My invention hasreference toan improved apparatus for treating textile fibers or ma# J terials-such as rags, paper-pulp', wQol,1cot-. Io ton, yarn,'&c.; and it consists i`n certainj'mprovements, all of which are fully set forth 1n the .following specification, andl shown in the accompanyingdrawings, which formpart f Q thereof.

15' In Letters Batent granted tome March 2, 1886, No. 336,928, is'described an improved drying-machinefor drying Woolgcotton, yarns,

5&0., by causing them to ypass back and forth through a chamber by means of endless aprons, 2o through which. chamber` and material to be j dried currents of air or vdrying media are caused tol pass. Inthis application my ob- `ject is to combine the principles involved l'in the saidl machine with suitable means for atomizing or spraying wet colors or disinfect-' ants or other liquid with which the material 'isltQ be treated, and causing'it or 'disinfectant, bleaching,tor'eoloringgases to bel drawn in with the passing drying air or gasand 3o made toact upon the materiaLWh-i'chis being conveyed back and forth throughqthe chamber. If the supply of 4color or disinfecting mediarbe uniform, every portion of the yarn, lwool,A cotton, 8nd, will be treated therewith to 3 5V the same degree, andaftersbeing treated -with said .sprayed material it will be dried beforeemerging from the machine. By thislmethod materials may be bleached, disinfected, dyed, `or colored in a speedy and convenient manner, reducing the cost and labor necessary to accomplishthe, desired result.l

lThe machine could be used to advantage where-delicate-tinting wasv required, asthe coloring-matter, being heldin suspension by the passing air, will permeate every portion .of the'material'being carried throughthe ma.. chine.

chamber, and may be formed of link-chains endless conveyers vor `ing retained therein as long a time as necesteeth or projections'to more securely hold the A B are two endless aprons, between which the wool or cotton7 &c., to be dried is held and conveyedthrough the drier or hot-air with slats between; or webbing, netti-ng, or combinations of any two or more of these may be used', the particular construction .ofthese aprons being limmaterial tomy invention. rlhese aprons A B lie close'upon each other in passing through the' heating or drying chamber H and while passing around andover the guide-rollers G G, moving back and.` forth or up and down through vsaid chamber for` the purpose of be- 1- sary.` The apron -A -is guided outside vthe chamber H by rollers K, and apron'Bby roll-l ersEE. l M D is the feeding end, and may be of any`suitable construction, and the yarn, wool, or c'ot. ton to be dried after being fed upon the apron' B is carried up over rollers Fand between it and the apron A,whichpasses.around roller` K and enters the drying-chamber H through 7 5 opening h, and while held ,between the aprons (and, if desired, prevented from displacement by slats C thereon) is conveyedA over rollers 1 't' 'G G, and, after passing back and forth a nurnber of times emerges byapertures h'to4 the The traveling aprons may be made in any manner desired, but shouldvbe of open netting 4 orwebbing secured tol chains on its lateral 85' edges, and maybe furnished with slats, which would be preferably on the-top Aof the net-,work

-or next to the 'cotton,iwool, yarn, &c., Ato be dried, so as' to prevent the same from being displaced on turningover the drums or pulleys in transit through the heating apparatus. The netting maybe formed of cord or twine or-their equivalent, and, if desired, the slats may have-- materialto be driedfrom displacement; The. cotton, wool, Ste., or yarn in skein or Warp,f may be deliveredto the endlessaprons and conveyed -through the drying-chamber. This drying-chamberf H may be `simply a large chamber, yinto or throughwhich hot air .or gas is forced or drawn by one or more blowers o r faust-J, or by any other means, the ingress or 8o i` 'outside of the chamber, and the material from= `between the said aprons is discharged at W.

egress of air being allowed by the openings, as at the top or bottom, for instance, asat I. When th'e air-currents and aprons pass in the same direction through chamber H, the up- 5 per part of the chamber maybe made conical or dome shape, as at Q, and`projecting into theopening is a. pipe, L, terminating in a rose nr spraying-nozzle, M, as indicated in dotted lnes. Y.

O is an injector or device for forcing the dis` infectant or coloring medium or liquid through pipe L, the liquid being supplied from a tank, N and its ow controlled by a valve, n..

is a blower connecting by a pipe, p, with the injector O, whereby a forced current of air may be used to propel-and subdivide or spray the disinfectant or coloring fluid. vIn placeof a fan the fluid may be sprayed by the use of a. jet of steam, in which case the pipe p would connect with the boiler; or, if desired, 'the fluid could be pumped' through the nozzle M and,

' sprayed under great pressure, as indicated in dotted lines Fig. 1, the particular method or apparatus used' for spraying thefluid being immaterial to my invention. fs

When the ai r-cnrrents and aprons pass in opposite directions, the disinfectant or bleaching or coloring matter is preferably sprayed into the chamber between the aprons at one or more places near where they enter, as indicated by solid lines at M, preferably so as to act upon .both sides of the material to be treated.

Any form of disinfecting gas or iuid might be used-as, for instance, Burnetts or Condysand the acoloringmatter, if desired, may be mixed with the disinfectant or may be used separately. The disinfectant may besupplied from one set of pipes, and the coloring-solution from another set of pipes, 'both being fed 4o simultaneously to the air-currents passing through the machine; or, if desired, either one Y may be used without the other. The air used as a drying medium may, if desired, be heated before passing through the machine by being caused to pass over the hot surfaces, as indicated in Fig. 2, dotted lines. l

This apparatus is equally applicable for impregnating' the materials conveyed through it .with any other substances in the liquid or 5o gaseous state.

In this application I do not claim the process, (as that forms subject-matter ofxanother application of mine, bearing even date with this, and serial numbered 196,643.

Having now described my invention, what I claim as new, and desire to vsecure by Letters Patent, isV 1. A close drying-chamber through which a drying medium is caused to circulate, in combination with two endless aprons adapted to 6o lie Jclose together to hold the material t0 be dried, and arranged to pass back and forth within the drying-chamber, the aprons being brought outside .the chamber at vtwo places, one to form the feeding and one to form the discharging parts thereof', whereby the goods to be dried may be placed upon the aprons and then conveyed through the drying-chamber, and after being dried discharged again, guiding-rollers for the aprons, land suitable devices 7o for injecting into said drying medium a fluid or gas which is conveyed to the material to be dried, and caused vto act thereon, the drying, medium being the vehicle by which the fluid or gas is brought into contact with the material to betreated and dried, substantially as and for the purpose specified.

2. The combination of the inclos'ed dryingchamber having openings for the admission of .the endless belts, and provided with openings, with a'fanfor blower to cause a circulation of air through said drying-chamber, thetwo end` less belts or aprons, guidingrollers therefor to guide said aprons back andfort-h in said drying-chamber and in 4the path of the air-currents, and convey the said apronsoutside or exterior to the'closed chamber at two places for the feed and discharge, and suitable devices for injecting into said drying medium a fluid or gas, which is conveyed to and through the material to b dried and caused to act thereon,

the drying medium being the vehicle bywhich `-the fluid is brought into contact with the material to be treated and dried, substantially as and the purpose specified. 95

In testimony of which invention I hereunto set my hand.
