"The present invention relates to an improved support for the drawing-roll mechanisms in spin ning machines.
A plurality of such mechanisms is usually placed on a longitudinal support rail Whose. ends are supported by transverse support walls or frames of the machine. The unsupported part of the rail has a tendency to sag which causes an undesired displacement of the bottom roll stands. The grooved rolls are then properly supported only at the support frames of the machine. This can be remedied by re-setting the bottom roll stands and possibly inserting shims after loading of the drawing-rolls and after equilibrium of the tensions in the machine has been reached. Such make-shift arrangements, however, are unsatisfactory and are insufficient soon as the load on the drawing-rolls changes.
It is an object of the present invention to provide means for additionally and adjustably supporting the support rails for the drawing-roll frames in spinning machines. These means comprise frame members interposed between the conventional machine support frames and have a leg portion having a foot resting on the longitudinal member on which the spindles are mounted, and have an upper arm extending underneath the rail on which the drawing roll frames are mounted. Screws are provided for adjustably connecting the upper arm of the supplemental y frames and the rail or angle iron supporting the drawing-roll frames.
Further and other objects of the present invention will be hereinafter set forth in the accompanying specification and claims, and are shown in the drawings which, by way of illustration, show what I now consider to be a preferred embodiment of the invention.
In the drawing:
Fig. l is a schematic, fractional side elevation of a spinning machine frame equipped according to the invention;
Fig. 2 is a large scale, schematic, fractional, cross-sectional view of one side of a spinning machine equipped according to the invention; the other side is symmetric to the one shown.
Like parts are designated by like numerals in both figures of the drawing.
Numeral i designates an angle-bar supporting the stands 2 carrying the grooved bottom rolls I, II, III, IV to which the top rolls I, II, III, IV are pressed by means of a system of saddle members 3, 4, and 5. A hook 6 extends from saddle member 5 underneath the drawing rolls. The lower end of hook 6 is connected to a link I on I which a pull is exerted in the direction of the arrow in Fig. 2 by means of a weight or a spring in the conventional manner. Since there is no load on the drawing mechanism when the spin ning machines are assembled in the factory Where they aremade, it cannot be anticipated how much the horizontal leg I of the angle iron supporting the drawing-roll frames will be defiected. by the pull on rod 1 when the machine is in practical operation.
According to the invention, a supplemental support member 9 is provided between two conventional support walls or frames 8 which rest on the ground. This supplemental support member is free of the ground and has a leg portion H] at each side of the machine provided with a foot which rests on and is bolted by bolts 1 I to a longitudinal bar II on which the spindles I5 are mounted. In conventional spinning machines, the bars I l are usually bolted to the conventional transverse frames 8. The supplemental support members 9 have an arm I2 extending upwardly and underneath the horizontal leg I of the angle-bar l. Leg I rests on the upper ends of adjusting screws 13, which are screwed through a horizontal portion at the upper end of arm 12, and is pressed to screws I3 by means of a bolt M. This connection of mem-- hers I and 9 can be adjusted even when the ma chine is in operation and permits the placing of leg I of bar I in exact horizontal position for correct support of the stands 2.
Stability of the machine is improved by the provision of the additional transverse frames 9. The latter are so constructed that they can be easily inserted in the assembled machine. They are easier to mount than the support frames 8 Whose distance apart can be increased and whose number can be reduced when using the supplemental supports according to the invention, without sacrificing stability of the whole machine frame. If loads and stresses on a spinning machine equipped according to the invention are changed, the correct positionof the supports for the drawing mechanism can be restored in situ by manipulation of the bolts l4 and adjustment screws l3.
While I believe the above described embodiment of my invention to be a preferred embodiment, I wish it to be understood that I do not desire to be limited to the exact details of method design, and construction shown and described. for obvious modifications will occur to a person skilled in the art.
I claim:
1. In a spinning machine, spindles, drawing mechanisms, a machine frame including a horizontal bar for supporting the spindles, another horizontal bar for supporting the drawing mechanisms, at least two support walls placed transversely to and connected with said bars and adapted to rest on the ground, and supplemental rigid frame means disposed free of the ground, transversely to said bars, and between and parallel to said support walls and being also connected with said bars.
2. In a spinning machine as set forth in claim 1, said supplemental frame means comprising a leg portion having a foot resting on and being connected with the bar for supporting the spindles and having an arm extending underneath and supplementally supporting the bar for supporting the drawing mechanisms.
3. In a spinning machine according to claim 2, adjustment screws interposed between said arm and the bar for supporting the drawing mechanisms for adjusting the relative position of said arm and said bar.
4. A spinning machine having two sides, spindles, drawing mechanisms, a machine frame including a lower horizontal bar at each side of the machine for supporting said spindles, an upper horizontal bar at each side of the machine for supporting said drawing mechanisms, support walls resting on the ground and placed transversely to and interconnecting the bars at one side of the machine with the bars at the other side, and supplemental frame members having foot portions resting individually on the lower bar at one side and on the lower bar at the other side of the machine and having arm portions extending individually underneath the upper bar at one side and the upper bar at the other side of the machine and being adjustably connected with said upper bars.
5. A spinning machine as defined in claim 4, one of said supplemental frame members being placed between always two of said support walls and rigidly interconnecting the bars at one side of the machine and the bars at the other side.
