Filed Dec. 18. 1929 7W 14,5- A M 4x" Patented July 5, 1932 UNITED STATES PATENT OFFICE WALTER HENGST, OF GHEMNITZ, GERMANY CONTROL BUTTON FOR THREAD BOBBINS Application filed December 18, 1929. Serial No. 415,08.
10 are known, for example wooden buttons with differently coloured heads and split, slightly resilient pins, but with these known means it was not possible to. mark the threads differently as is desirable for an accurate 15 control and regulated manufacture.
These disadvantages are overcome by the present invention which is illustrated by way of example in the accompanying drawing,
Fig. 1 shows in section the control button inserted in the bobbin.
Fig. 2 is a top plan view of Fig. 1.
Fig. 3 shows the lower part of the control button in side elevation.
Fig. 4 is a top plan view of Fig. 3.
Fig. 5 shows the top part of the button in side elevation.
Fig. 6 is a top plan view of the top part of the button.
One or more spring arms Z) are fixed to the bottom a of the button, said arms serving to fasten the button on the bobbin or cardboard sleeve. The circular slightly domed disc of the lower part a is provided with two diametrically opposite semi-circular or other suitably shaped indentations 0, d.
The upper part, Figs. 5 and 6, has the shape of a frame of curved cross section with two diametrically opposite tongues e, f bent downwardly and inwardly adapted to be inserted through the indentations c and d of the lower part thus producing a secure connection between the two parts when the upper part is turned in relation to the lower part through a quarter of a revolution, after the marking plate 9 made of celluloid, paper or other suitable material has been placed be tween the two parts.
By this means it is possible for the user to himself change the marking plates which are either ready printed or arranged for writing. The control buttons may be supplied finished and closed.
In order to obtain the greatest possible and most easily distinguishable marking, both the marking plates 9, as well as the frame shaped upper part may be made in different colours and the plates 9 may, as already stated, be ready printed or arranged for taking writing.
In order to obtain a good hold of the control buttons in the bobbin tubes, the control buttons are made of a hollow shape, adapted to the bobbin tubes.
I claim 1. A control button for thread bobbins comprising in combination a lower disc shaped part having two diametrically opposite indentations in its edge, spring arms extending from said lower part designed to be inserted in the thread bobbin, an upper frame-shaped part colored corresponding to the thread, and downwardly and inwardly bent tongues arranged on said upper part adapted to engage with said indentations of said lower part.
2. A control button as specified in claim 1, comprising in combination with the upper and the lower part, a control plate of suitable material and arranged for marking and adapted to be inserted between said upper part and said lower part.
In testimony whereof I afiix my signature.
