APPARATUS FOR MOISTENING' THREADS Filed May 20 1930 Patented Nov. 14, 1933 UNITED STATES PATENT OFFICE Aceta G. in. b. H., Berlin-Lichtenberg, Germany, .a corporation of, Germany Application May 20, 1930, Serial No. 454,128, and
in Germany 3 Claims.
The present invention relates to a device for the uniform wetting of threads and more particularly of artificial threadsv made according to a dry spinning process which before bein worked up into textile materials, are provided on their surface with a wetting or lubricating agent rendering them supple for the following operations. Additional objects of my invention will be seen from the detailed specification following 1 hereafter.
According to my invention, a regular wetting of a large number of threads with equal amoifiits of the liquid to be impregnated and without loss of the latter is obtained by supplying each lubricating or wetting device of a form de-.
scribed hereafter, automatically under pressure with exactly the amount of liquid calculated to be applied to the thread. The thread receives the wetting liquid directly at or below a narrow bore-hole from which the liquid flows out. The device according to this invention makes it possible-that not a drop of the liquid is lost and that the same amount of liquid is forcibly transmitted to the thread in each unit of time. The uniform distribution of liquid delivered on a large number of lubricating devices is secured by mounting before the orifice of each device a throttle resistance of exactly the same size and of such a diameter that the other resistances may be neglected.
The accompanying drawing illustrates the process and the device according to the invention.
Figs. 1 and 2 are a front view and an end view respectively of the lubricating system having a large number of lubricating points.
Figs. 3 to 5 illustrate a special form of construction of the lubricating device in which the thread receives the wetting liquid directly at the orifice.
in which the thread receives the liquid ejected from the orifice at an edge below the latter.
Y In Fig. 1 a is the pressure piping for the wetting liquid which extends the whole length of the spinning machine. Pipes b branch off at distances corresponding with the single spinning places. Each of these branches b has a wetting nozzle 0 against which the thread d travels in a slight bend or break, if necessary. Having passed the wetting nozzle the thread is wound, for instance, ona spool e or on any other collectin't orwinding-on device. The piping a contains a manometer ffor the purpose of ascertaining that the prescribed pressure of the liquid is maintained.
Figs. 6, '7 and 8 show another form of the device May 23, 1929 The pressure maintained in the piping a, ob-
viously, is dependent from the quantity of liquid to be delivered on the thread, from the viscosity of the liquid and, finally, from the diameter of the bore in the nozzle. It may be varied according to the specific circumstances from about 0,01 atmospheres to about 0,1 atmospheres.
Figs. 6, '7 and 8 show an alternative form of the nozzle. Fig. 6 is a plan, Fig. '7 a longitudinal section and Fig. 8 a front view. For the purpose of varying the amount of liquid which is ejected from the nozzle, without varying the pressure in the piping, and for simplifying the manufacture of'the nozzle device itself, exchangeable cylin-' drical capillaries i'of equal bore and length regulating the resistance of flow through the nozzle are fitted into the latter. The liquid flowing out from the boring g is collected at a striking edge It, whence it reaches the thread d in an uninterrupted and uniform manner.
The pressure piping a is connected with a. supply vessel containing the liquid to be applied on the threads. By a suitable pump a uniform pressure regulated, if necessary,.by a valve, is maintained in the device controlled by the manometer I. These pressure devices known in the art, are not shown in the drawing.
Numerous other embodiments are possible and I contemplate as included within my invention all such modifications and equivalents as fall in the scope of the appended claims.
What I claim is:- I
l. A device for regularly wetting or lubricating a plurality of threads comprising a system consisting of a main conduit, a pluralityof branch conduits connected with said main conduit and terminating in a plurality of means for discharging liquid therethrough and for simultaneously providing the sole restraint to the uncontrolled discharge of said liquid from said system, and means for providing said main conduit with liquid under pressure, each of said discharging and restraining means being a nozzle having therethrough a capillary bore of substantial length.
' 2. A device for regularly wetting or lubricating .a plurality of threads comprising a system consisting of a main conduit, a plurality of branch conduits connected with said main conduit and terminating in a plurality of means for discharging liquid therethrough and for simultaneously providing the sole restraint to the uncontrolled discharge of said liquid from said system, and
means for providing said mainconduit with liquid under pressure, each of said discharging and restraining means being a nozzle having therethrough a capillary bore of substantial length and hearing at its bore a guide for the thread.
3. A device for regularly wetting or lubricating a plurality of threads comprising a system consisting ofa 'main conduit, a plurality of branch conduits connected with said main conduit and terminating in a plurality of means for dischargrelatively high resistance to the outflow ot the a liquid and bearing at its bore a guide for the thread.
