MECHANISM FOR DRAWING FIBERS WITH ENDLESS BELTS.
Specification of Letters Patent.
rfraamtea sept. 18, 1917.
Application led March 12, 1917. Serial No. 154,357.
To all whom it may concern:
Be it known that l, FERNANDO CASA- BLANc-As, a subject of the King of Spain, residing at Sabadell, Barcelona, Spain, have inventedcertain new and useful Improve- Vments in Mechanism for Drawing Fibers with Endless Belts, of which the following is a specification.
My invention relates to drawing mechanisms for textile rovings used in spinning frames or other spinning machinery in which there is employed one or more belts to carry the'roving to the drawing rollers. These mechanisms are usually composed of two endless straps or belts trained over rollers which drive them; said belts being guided by rods or rollers of small diameter so that the two belts come into contact one against the other along one of their sides. The roving passes conduct it to the drawing rollers and retain the fibers which have not yet been caught by the drawing rollers so as to avoid such bers being picked off and dragged along by the bers which have already been drawn by the drawing rollers. Sometimes there is employed in these mechanisms a plate or a series of rollers instead ot one of the belts, the mechanism beiner then composed of a fixed late and a belt that runs in contact with t e plateand the roving passes between the plate and the belt.
In the operation of present devices it occurs that the belts are made to shift 'from side to side with evil results to the drawing; this sidewise movement being the combined result of the rotary movement of the rollers, the unevenness in the thickness and in the surface of the belts, and the varying thickness and lateral movement of the rovings that pass betweenthe belts.
My invention has for one object to obtain a device that prevents eiectively the transversal slipping of the belts so that they work constantly inthe proper position to obtain the best results.
Another object of my invention is to provide a simple, eiiicient, cheap and readily at tachablc and detachable support Jfor the rods or other members that Guide the movement of the. belts and force tem to contact one against the other; such support being constructed to receive and uphold also the plates or rods that may be substituted for one of the belts.
My invention consists of two metal sheets between them, and they v or plates separated one from theotherat a distance corresponding to the width of the belts, and cut in such 'manner thatl they'can rest on the driving rollers or' on the drlving and on the feeding rollers. 'Said 'plates guide the belts and support 'the guidingl rods of the belts acting therefore as belt guides and guidinglrod supports.
During t tween the two guiding plates, andas these plates rest on the driving and the feeding rollers, transverse slipping of the belts is prevented. At the same time the belts keep the support in balance having very little rubbing ongthe rollers.
e drawing, the belts move be-l` the driving rollers or onboth It tho guiding rods are exterior to the` l bcltsthey may be secured to the plates, serving atthe same time to strengthen them; if they are interior they are putin slots-made in the plates,so that it is My invention maybe applied to various devices for effecting drawing by belts, for example, when thereare' employed exterior guiding rods, guiding plates instead of rods, interior guiding rods, a plate instead of one of the belts, as in the simple drawing and previous drawing by belts.
The accompanying drawings show a guidinof support according to my invention.
Figs. 3 to 7 are different' .forms'ot the support. v
easy to take them y, oi when the support has toA be taken out. 1
Fig. 8 is an elevation or' the support sus"" pended from the upper driving roller with an extension resting on the feeding rollers.
Figs. 9.and 10 showthe su port combined with belts to produce the pre ing.
The apparatus consists of the'plates or metal sheets 1, 2, duly separated to'allowthe belts 3 and 4 to move between them, which belts are operated in the known way by the driving rollers 5 and 6. The have t e rear portions strengtl'iened by the rods 8 and 9, serving at the same time as exterior guide 'for the belts 3 and 4.
Fig. 1 represents in dotted lines the relaplates 1 and 2 iminary draw A tive positions of the drawing rollers y17 and i 1S andthe feeding rollers 19 and 20. In the other figures these rollers are omitted. In Figs. 1 and 2 the belts and the driving rollers are representedinfull lines, andpin the other figures only the support plates represented in 'l'iill lines. "llie hole il made in the support plates has for its object to ilii'ninish the i'velglit and peiiiiit oi tlie inspection of the working ot' the fielts.
The form in Fig. 3 diiers only lroin Fig. l in that the belt 3 has two exterior reds 8 and 8 and the belt l has an interior guide rod 22, and the plates l and 2, that constitute the' guiding support, are inserted in .a groove 21 made in the lower roller 6; this sanie arrangement being shown in Fig. 5. Furthermore, to strengthen the plates l and 2', the lower edge is extended to reach the brace 25'. The ends of the red 22 rest in slots inade in the plates l and 2.
Fig. el shows my invention applied in the case where the lower belt is replaced by a plate 24, which plate is riveted or secured by its ends to the plates l and 2 of the guiding'support, or it is fitted to tliern in any other convenient r'nanner,
- -ln Fig. the guiding supports l and 2 are appl ied to tlie'ease where the belts have interior guiding rods 22 and 23 these rods resting on the plates l and 2 in the saine way as represented in Fig. 3. To the end that the plates l and 2 be suliiciently strengthened, they are extended at the lower ends forming lugs wherein the brace 25 is fitted. v
Fig. 6 shows the guiding support applied tothe case wherein the upper belt is coinbined with an exterior half round guiding rod 8, and the lower belt with an exterior rod 9 also half round and with an' interior rod 22.
Fig. 7 illustrates the modification of the guiding plates lv and 2, necessary to adapt thein to receive an upper belt with a half round guiding rod 8 and a. lower belt with an interior plate 30. The form shown in Fig. 8 differs from the others in that the plates l and 2 instead of resting on the lower driving roller 6 and on the axle-ncck 7 of the upper .roller 5, l'ii'i'ng'tioin said neck 7 and are extended at their rear ends, forming the tails 2G which rest against'tlie axle-neck 19 of the upper feeding roller 19 and on the lower roller 20, preventing them revolving around the axle-neck 7 The brace 10 of the rear part is approximately in the saine position as in the other figures.
Figs. 9 and l0 show censtruetions which are applied in cases where a preliminary drawing is' worked with a belt and a plate 27, as inFig. 9, which plate is riveted or fixed to the support plates l and 2 a's indicated, or the preliiii'inary drawing is eieeted with two endless belts, as in Fig. lO. ln these cases also the support plates 1 and 2 carry the tails 26 toestablish contact with the feeding rollers 19, and at the saine tiine to guide the belts for the preliminary drawing. These tails 26 are wider than shown iii Fig. 8, lo support the guiding rods 28 and 2U shown in Fig. 10, aiid the rod 28 and plate 27 which in Fig. 9.
It is obvious that those skilled in the art may vary the details of construction and arrai'igeinents of parts without departing troni the spirit of iny` invention, and therefore I do not wish to be limited toV such features except as may be required by the claims.
