DOUBLE TWIST TWISTING SPINDLE Filed May 1, 1936 Patented Mar. 8, 1938 PATENT OFFICE 2,110,320 DOUBLE TWIST TWISTING SPINDLE Otto Bochmann, Bemschcid-Lennep, Germany Application May 1, I
1936, Serial No. 71,401 h n Germany May 10, 1935 2 Claims.
This invention relates to inclined double-twist twisting spindles driven by an endless driving element. Spindles of this type are usually arranged on a common spindle rail, so that the 5 -spindles have to be accurately adjusted singly in order to obtain an almost uniform pressing of the spindles against the driving element. This arrangement suffers of the inconvenience that, gesides the complicated arrangement, a
uniform pressure cannot be ensured at all points as the pulled side is always slack relative to the pulling side.
It has become known for simple vertically arranged twisting spindles to arrange them independently on each other in individual bearing arms so .that in this instance a uniform pressing of the spindles against the driving element is ensured. This construction has, however, the defect, that owing to the preserving of the common spindle rail and to the addition of separate bearing pins for every single spindle the machine becomes complicated and expensive. Every spindle must have an element which presses the spindle against the driving element. This pressing element consists usually of a spring or of a weight. The machine is not only more complicated by the arrangement of these pressing elements but is less easy to survey and inclined to disturbances of service as the auxiliary elements producing the pressure are liable to fail.
These inconveniences are obviated by the invention which consists in that the inclined double-twist twisting spindles driven by an endless driving element and oscillatably mounted independently of one another in individual bearing arms are suspended on a common support so that the wharves bear by gravity of the spindles against the driving element. Brake surfaces are preferably provided against which the individual 40 spindles are pressed for stopping their rotation,
and holding devices are also provided for maintaining the spindles in disengaged position and out or contact with the brake surfaces so that the spindles can be rotated freely by hand.
This construction presents the advantage that, as in the twisting spindles of known type, a uniform pressing-on pressure is obtained, the manufacturing being simplified and the cost of manufacture reduced. The spindles are suspended on a common support so loosely that they produce by gravity the pressing-on pressure. All auxiliary elements and a special bearing of the spindles are avoided and the machine is of simpler construction and more reliable in serv- 55 ice owing to the simple arrangement of the spindles as the gravity of the spindles is always at disposal so that the pressing on pressure exists permanently.
/ An embodiment of the invention is illustrated by way of example in the accompanying drawing in which:- 5
Fig. 1 is a side elevation of the improved spindle.
Fig. 2 is a section on line 2-2 of Fig. 1.
Fig. 3 shows diagrammatically the 'total arrangement of such a drive. 10 The double twist twisting spindles l are mounted each one in a bearing arm 2, these arms being loosely suspended on a common support 3 so that the spindles bear with the wharves by gravity against the driving element 4. Holding 15 devices 5, designed to hold the spindles in the disengaged position, are arranged one opposite each spindle, a stopping element 6 of each holding device engaging in a corresponding recess of the spindle. Opposite each spindle a brake sur- 20 face I is arranged designed to stop the corre-, sponding spindle if the same is pulled against it, but to liberate the spindle in disengaged position for further attendance if the spindle is released. Fig. 3 shows that in an endless belt drive, in which the pulled side is slack or loose relative to the pulling side, every individual spindle can adapt itself to these differences so that, without any auxiliary means, a general uniform pressingon pressure the spindles is ensured. 30
I claim:-- 1. Inclined double-twist twisting spindles driven by an endless driving element, comprising in combination with the driving element and the spindles, a wharve on each spindle, a conmion 35 support extending in parallel to the driving element, an angular gravity-controlled arm comprising a vertical and a substantially horizontal portion, and mounted to oscillate about the support, and a bearing for the corresponding spindle 40 in the substantially horizontal portion.
2. Inclined double twist twisting spindles driven by an endless driving element, comprising in combination with the driving element and the spindles, a 'wharve on each spindle, gravitycontrolled oscillatably mounted spindle-bearing means for holding the individual wharves against the driving element, a brake surface arranged in. the path of oscillation of each spindle, said spindle adapted to be swung to bring its wharve into contact with said brake surface to bring said spindle to a standstill, and a holding device adapted to maintain said spindle in disengaged position freely rotatable by hand and out of contact with said brake surface.
