SPINNING-FEE.

Application filed July 17, 1917. Serial No. 181,149.

Be it known that-I, FERNANDO. Casnntan- 'cAs subject of the King of Spa1n, res1d1ng at Eiabadell, Barcelona, Spain have invented certain new and useful Improvements in Spinring-Frames, of which the following is a specification. I

This invention refers to. the spinning frames and similar machines in which, in

orderto convey the roving to the drawing cylinders two endless belts guided by suitable guiding rollers are employed, which belts grip the roving exerting pressure upon it and convey it to a point near to the drawing cylinders. My invention specially refers to the spinning frames of this .kind that are described in my former Patent lflo. 1,147,676 and in my patent application Serial N 0. 11,303 filed the 1st of March 1915.

The machines of my former patents and in general all the spinning frames in which two endless belts are employed to grip the roving and convey it to the drawing cylinders, although they produce a work of excellent quality, they present the disadvantage that the lower belt isinaccessible and in the event that it becomes broken or spoilt i; is very difficult to repair it, as it is necessary to stop the machine and to withdraw the upper belt and the guiding rollers of same, in order to attain the lower belt, and if this belt has to be withdrawn it is necessary to disassemble the driving cylinders taking a great amount of time and work.

My invention has for object to obtain a.

spinning frame similar-to the machines described in my cited former patents in which all these troubles due to the use of the lower belt are prevented thus obtaining a machine of simple construction and steady working.

ing passes between the plate vand the belt and is dragged along by the motion of the belt, being compelled to advance slowly to-. ward the drawing-cylinders following the movement of the belt. At the same time owin to the pressure that the belt exerts on the p ate, the required retention of the roving is obtained to prevent that the fibers that are seized by the drawing cylinders drag along the other fibers of the roving that have not yet been seized by the drawing cylinders.

With my invention I prevent completely the inconveniences of the machine already known, as the plate is fixed on the machine and therefore cannot be deranged and if the belt is deranged, as it is placed over the plate, it is very accessible and therefore easy to repair or substitute without interrupting the workin of the spinning frame.

In describing my invention in detail reference' will be had to the accompanying drawings wherein like symbols refer to like or corresponding parts throughout the several views and in which:

Figure 1 is a cross section of the drawing mechanism of a spinning frame according with my invention, Fig. 2 is a plan view of this mechanism and Fig. 3 is a detail. In Fig. 2 the standards and the supports of the lower cylinders have been omitted for greater clearness, leaving merely the arms that support the upper cylinders. Moreover in the right hand part of the Fig. 2 only 3, a pair of intermediate cylinders 86, 87

and a pair of feeding cylinders 88, 89, as in the drawing mechanisms of the usual spinning frames. The standards 72 that carry the whole mechanism, as well as the support 82 that carries the lower cylinders and the arms 80 that carry the journal bearings of the upper cylinders are of a similar construction as the ones used commonly in the drawing mechanisms of the spinning frames or other textile machines.

This invention consists of disposing between the cylinder 87 and the lower drawing cylinder 3, a plate 9 fixed on the supports 82 with screws 10, which plate has its upper face corresponding approximately to the tangent plane of the cylinders 3, 86, 87; said upper face of this plate 9 may be flat or slightly convex. Over this plate 9 rests an endless belt 1 disposed embracing the cylinder 86 and a roller or rod 5 of small diameter located very near to the drawing cylinders 3. This rod 5 is supported by means of resilient supports 29 which tend to press the rod 5 and therefore the belt 1 against the plate t). .The strength of these supports 29 may be adjusted by means of respectlve screws 30 screwed to the plate 9 and WhlCh serye at the same time to fix said supports 29 to the suitable position. The belt 1.

is mounted tight on the cylinders 5 and 86 in order that through the tension of the belt and the pressure that the cylinders exert the belt bears on the plate 9 with suflicient force to retain the roving.

belt in the art that bears against the plate.

exertsa so ter pressure on the roving, sulficient to retain the rovlng and oblige 11; to

. advance following the moyement of the belt but at the same time allowing the fibers o the roving that are caught by the drawing cylinders to slide between the other fibers of the roving and between the belt and the plate following the speed of the drawing cylinders and without dragging along with them the other fibers that have not yet been caught by said drawing cylinders. I

If for any reason during the working of the machine one of the belts is broken or split the corresponding cylinder 86 can be readily lifted, and roller 5 and belt 1 be withdrawn wlthout interrupting the working of the machine. Then the belt may be repaired or substituted by a new one, the rollers replaced in the machine and the spindle .corresponding to the damaged belt may be started again.

I have shown and described a preferred and satisfactoryconstruction but desire it to be understood that slight changes may be resorted to without departing from the spirit and scope of my invention, provided such caught by changes fall within the scope of the appended claims.

I claim:

1. Ina spinning frame, an endless belt to convey the roving to the drawing cylinders, a fixed plateover which said belt slides, said belt being tight and pressed against the plate, the roving passing between said belt and plate so that it is dragged along by the movement of the belt and conveyed to the,

drawing cylinders.

2. In a splnnmg frame, a fixed, plate over which slides the roving, an endless belt that slides over said plate and drags along in its motion the roving, a pair of driving c linders that grip said belt and roving and rive them, and a guiding rod for the front curve or loop of the belt; being said belt tight between said guiding rod and the upper driving cylinder; said guiding rod being mount-' ed so as to press the belt against the fixed plate, in order that the 'motion of the belt drags alongthe roving conveying it to the drawing cylinderstand the pressure of the belt on the roving retains it sufliciently to prevent that the fibers caught by the drawing cylinders may drag along with them the other fibers that have not yet been caught by said drawing cylinders.

3. In a spinning frame, the combination of a fixed plate over which slides the roving,

an endless belt that slides over saidplate and drags along the roving .in its motion la. e t

rotary driving cylinder that drives said b to conveythe roving to the drawing cylinders, a guiding. rod located very near to the drawing cylinders that guides the front curve or loop of the belt, said belt being suitably tight between said driving cylinder and said guidin rod; a spring acting on said iding ro the p ate in order that the belt drags along theroving in its motion conveying it to the drawing cylinders, and thepressure of the belt over the roving produces over it a suflicient retention to prevent that the fibers the drawing cylinders can drag along with them the other fibers that have not yet been caught by the drawing cylinders.
