Patented June 10, i930 UNITED STATESKPATENT OFFICE J'OHANN CARL HENSING, OF AERNHEM, AND JAN WILLEM LUBBERHUIZENQ OF EBB, NETHERLANDS, ASSIGNOBS TO NAAMLQOZE VENNOOTSCHAP NEDERLANDSCHE- KUNST ZIJ'DEI FABRIEK, 0F ARNHEM, NETHERLANDS SPINNING sown Application filed June 5, was, Serial No. acacia, and in the Netherlands September 22, rear.
Our invention relates to a spinning bowl, particularly for use in the artificial silk industry.
The spinning bowls hitherto in use have flat bottoms, this construction having been considered essential to the formation of a good cheese. It has, however, transpired that there are advantages, hereinafter set out, in not having the bottom flat.
According to our invention, therefore, the spinning bowl possesses the characteristicthat its bottom has a central depression, which may be circular or annular or other wise shaped. According to our invention said depression may also be designed so as to Widen out in the downward direction.
Our invention comprises also a form in which orifices for the discharge of li uids are provided at the under side of sai de pression. v I
-In the case of a spinning bowl. consisting of a plurality of parts and provided with an inwardly bent lower wall, the latter, ac-
' cording to our invention, may be furnished with a downwardlygb'ent portion adapted t be fixed, by rolling, pressing or other means,
in the central depression. Further, accord.-
ing to our invention, the depression may be filled up again after the downwardly bent portion has been fixed therein.
Two embodiments of our invention are illustrated, by way of example, on the accompanying drawing whereonz- Fig. 1 represents a vertical section through a spinning bowl provided with a depression in *accordance with our invent1on. V
Fig. 2 represents a vertical section .through a spinning bowl comprising a drawn aluminium shell and a foot secured thereon.
In the construction shown in Fig. 1, the spinning bowl consists of the shell 1,- which merges into the base 2 and the 'foot 3. .The base 2 is provided with a central depression 4, from which openings 5 pass obliquely outwards through the foot 3.v Said foot houses, in the usual manner, a bush 6 by means of which the spinning bowl is mountedon the spindle. Orifices 7 in thelower ed shell permitthe discharge, during the no tation of the bowl,.of the acid adhering to the fresh yarn.
According to Fig 2, the spinning bowl consists of a drawn aluminium shell 1 hav ing an inwardlybent lower wall 2 which rests upon the base and upon which the yarn lies in the shape of a cake or cheese.
In this embodiment, the foot 3 which depends from the base is of cast aluminium, and is made'with an upstanding flange 8 surrounding the shelll. The base is provided in its upper surface with a concentric depression 4. The wall 2 of the shell has f a downwardly bent central portion 9 secured in the depression 4 by pressing, rolling or other means. Liquid discharge openings 5 pass obliquely outwards from the e of the depression through the foot, whi e discharge orifices 7 are also provided in the vertical wall'of the shell. 9
One advantage of the last described spinning bowl is that, owing to-the depression 4:, the shell 1 with its lower wall 2 can be conveniently and firmly secured to' the "On the other hand, the provisionof a de-' pression 4 with discharge orifices5 enables the liquid that is introduced into the 'fun- 1 nel in spinning tobe discharged without coming into contact with the spun thread. In the ordinary spinning bowlnot provided with such a depression this liquid can only escape through the orifices? in the shell, so that spun cakes or cheeses of inferior quality often result.
What is claimed as new and desired to be 7 secured by Letters Patent is 1. A spinning bowl comprising a'shell,
a foot and a base, one of the latter parts having a concentric depression in its upper surface, .the depression extending substantially below the upper surface of the said part, the depression being flared outwardly in a downward direction, and liquid discharge openings leading from the base.
2. A spinning bowl comprising a base provided in its upper surface with a concentric depression, a foot depending from the base, a shell having side walls and an a inwardly bent lower wall, the lower wall resting on the base and being provided with a downwardly bent central portion secured in the concentric depression, and the depression extending substantially below the upper surface of the base.
3. A spinning bowl as claimed in claim 2, wherein the downwardly bent portion of the shell and the depression are flared outwardly in a downward direction.
4.- A spinning bowl as claimed in claim 2 k wherein 'the downwardly bent ortion 0t the lower wall of the shell and 51a depression are. flared outwardly ina downward direction, and wherein the base is provided with openings leading from the bottom of the de ression to permit of the discharge of liquid therefrom.
so In testimony whereof we aflix our signatures; n J OHANN CARL HENSING'. Y JAN W'ILLEM LUBBERHUIZEN.'
