'following' is a specification.

My invention relates to the manufacture or preparation of silk threads from the raw material, and one object of my invention is to provide an improved bath in which the raw silk may be soaked preliminary to putting' the same through the various opera-` tions necessary before the ranv material may be spun into thread forsubsequent use:

A further object of my invention is to provide an improved method or process of emulsifying liquids containing oleaginous material such as various combinations of oils whether such oils are of the same or different speciiic gravities.

My invention further includes apparatus in which this liquid bath or emulsion can be prepared, and the means employed in 'the preparation thereof in connection with the operation of said apparatusor any other form of apparatus in which such method or process involved in the preparation of the. improved soaking bath forming part of my invention can be carried out.

These and other features of my invention are more fully described hereinafter, reference beingl had to the accompanying drawings. in which:

Figure l is al perspective view, partly broken away, of my improved emulsifylng apparatus.

F ig. 2, is a sectional elevation, more. or less diagrammatic, showing apparatus within the scope of my invention and in which my improved method or process of emulsifying liquids can be carried out.

The apparatus shown in the accompanying drawings and which I may employ 1ncludes a tank of heavy construction, indicated at l and shown in the drawings as resting upon the floor 2 of a building in which the work may be carried on. In this tank I propose to make a combination soaking bath for raw silk comprising soap, oil and water; such ingredients being incorporated or combined and emulsified under the influence of heat, with provision for circulating the mixture through said tank until it is in proper condition for the desired purpose intended.

`Within the tank l are mounted, preferably at the sides of the same, steam pipes or coils 2, receiving steam from a suitable source such as a boiler l not shown, such steam pil es or coils being provided with suitable return connections 5 for the water of condensation which may pass through a suitable trap or traps) Gand thence to the boiler.

later from any suitable source may enter the tank via a pipe 7 having the usual controlling valve, Above the tank l I provide a soap boiler or other suitable receptacle 8 in which a soap solution of suitable character may be prepared; said receptacle having a pipe l0, suitably valved whereby the soap solution in any desired or suitable quantity may be delivered to the tank l. In addition, I provide another tank ll above the tank l, for the reception of a prepared oil for use in the treatment of silk; the improved bath which l propose for treating raw silk comprising an emulsitied body of a soap solution, water, and a. prepared oil, in suitable proportions. The tank ll is provided with a pipe l2 whereby the oil may be delivered to the tank l.

It is highly desirable that the oil be delivered in measured quantities, and for this purpose the end of the tank is provided with a gage glass 13 graduated in. inches and fractions of an inch, with a suitable index 14 whereby the volume of its contents may be read at a glance at all times.

After the desired quantities of water, soap and oil have been introduced into the tank 1, the mixture may be heated by forcing steam through the coils 2 within the tank, and this action may ltake place while the material is being emulsied. lt is highly essential that this emulsifying action shall be complete, and for this purpose I propose to rapidly circulate the liquid through the tank and through the perforated pipes therein while the material is heated. F or this purpose, the bottom of the tank is provided witha manifold, comprising a pipe l5 running longitudinally of the same, and having laterally extending branches 16 which with said pipe are perforated. The central portion of the manifold 16 is Connected to a pipe 17 leading` to a suitable pump 18, preterably ot the centrifugal type, and this pump receiving the liquid in course or" preparation, discharges the same through pipe 19, from which it may be delivered to the tank through pipe sections 20 and 2l connected to a pipe 22 disposed vithin the tank and having depending pipes 23. These latter pipes are perforated for the discharge or" the emulsitied liquid raised by the pump.

as the quantity ot liquid to be treated should economically be the same in preparing all batches of liquid, the tank is provided at the end 'with suitable gage glasses 25 graduated or having scales in inches and fractions thereof as Well as suitable indicia at 2G so that the contents of the tank may be read at all times. The height ot the tank is such that by preference tivo gage glasses are empioyec.

when the mixture is completed, it is to be drawn ott' tor use, and for this purpose the tank may be prov'ided with a depending discharge pipe 28, having preferably at its lower end a suitable nozzle 29 carried by swireled pipe 3() for convenient discharge into tank trucks or other suitable receptacles 3l. rllhe pipe 2e preferably has a valve 32 for controlling the discharge, andthe discli arge nozzle is preferably provided With a screen 33.

rllhe tank may be provided V-`with a cover 35, and the heating ot the liquid may le under pressure or vacuum, as may be desired, or the heating may be carried on at atmos pheric pressure.

I claim:

l. in apparatus for preparing a treating bath, the combination ot a tank, means for heating the same, liquid containers mounted above the tank and having discharge pipes leading` to the tank, a, perforated pipe in the bottom or the tank for collection of the mater'al contained therein, a perforated pipe in the top of the tank for the inlet of such material, a pump connected to said pipes for drawing the material from the bottom ot the tank and discharging it into the top of the same to insure proper circulation and emulsilieation thereof, and means for discharging the material troni the tank.

2. ln an apparatus for preparing a silksoaking bath, the combination of a tank, means for heating the same, soap and oil con rners mounted above the tank and each having a discharge pipe leading to the tank, a perforated pipe in the bottom ot the tank tor collection ot the material contained therein, a perforated pipe in the top ot the tank for the inlet of such material, a pump connected in said pipes whereby the inaterial may be drawn from the bottom of the tank and discharged into the top thereof to insure proper circulation and emulsiication, a pipe for discharging the emulsied 1naterial from the tank, a pivoted discharge nozzle connected to said pipe, and a screen for said nozzle.

THEO. VICKERSHAM.
