The pressesused in the Vwashing of wool and: other textile matters show lserious inconvenlences from the viewpoint of the spar-u ing of the matter to be squeezed as well as onaccount of the fact that the mode of driv-` ing of said upper roller through long-toothed gearing between both the upper and lower rollers causes speed of said upper roller every time a new tooth passes along; and

Second. A difference in the speeds o f the rollers, resulting from the upper roller being driven by long-toothed gearing and at the Y which must exist between both rollers if an effective squeezing effect is to b-e obtained. In order to reduce in av certain proportion such disagreement, the long-toothed gear of the upper roller is not, generally, keyed' on the shaft vof said roller, but is 'driven by means of a pawl or trigger, a ratchet-wheel being integral with the shaft of the upper roller which can, at giventimes and on acat an angularspeed greater than that which would result from a long-toothed gear drive. W'hen such device comes into action (which it can do in one direction'only), then the driving of the upper roller takes `place through' the point of contact,'which is detrimental to the material to be squeezed,said material undergoing a frictional strain which is greater inasmuch as the motion of the upper roller is different from that which is transmitted bythe long-toothed gears.

My invention has for its object a device by which said inconveniences are vobviated, the long-toothed gears being dispensed with and the driving of the upper roller being obv. main drive and eachl` roller. First. An instantaneous variation 1n the ments. y Y

Figures l and2 show, in front and side Vlews respectively,one o f these embodiments,

siderable on account of the great pressure count of the slope of the ratchet teeth, travel tained through an intermediatemember, the

axis of .which is positioned, as far as possible,

on a line substantially level with the center p of the upper roller in the non-operative position of thelatter.- Y ;Thisintermediate member by which my invention is characterized in its chief object may be interposed inthe driving mechanism either between both rollers-or between the It may consist, for instance, of a worm spindle and wheel, bevel or spur gears or any other known means, such means being, infaddition, combined so thatthe movement of rotation of the upper roller may be made wholly or substantially independent vof the lift 'offsaid roller in the ordinary limits ofK practice.

The drawingsappended hereto show, for mere indicative purposes, some possible embodiments of my above mentioned improve- Figurel being partly in section.

. Figs. 3 and 4 and Figs. 5 and 6 are, respectively, views similar to Figs.k l and 2 and show modifications of the invention.l

' Fig. vis a view similar to and illustrating l said shaft 39 drives, through gear 41, the shaft 8 of the lower roller 9 of the press. 0n`

the same shaft 39 are mounted sleeves44 and 45 on which gears 46 and 47 are free to rotate.

On `the other hand, the finely toothed gear 48 iskeyed at the end of shaft 39. `This gearV i drives, through a Vsuitably mounted idle gear 49, the removable or detachable gear `14. The

latter rotates shaft-50-on which it is 5 keyed and which bears heavily toothed pinions 60 and 61. Thesev two pinions drive, Vthrough the l,abovev mentioned loose gears 46 and 47 gears 53 and 54 fixed to shaft54 of the upper roller of the press.

` As gears 46 and 47 mesh with gears54 and 53 on a substantially'horizontal,line it follows that the upper roller of the press is able, together with its shaft 54', torise'an appreciable distance without any likelihood of the gears 46 and 447 becoming disengaged from gears 54 and 53. The mechanical drive of the upper Yroller is thus ensured, whatever thickness the layer of wool interposed between- rollers 2 and 9 may be, much more effectively than by ordinary long-toothed gears, a constant ratio being vat the same time maintained between the driving and the driven parts. By having th-e center of gear 46 just below the level of shaft 54 when the upper roller 2 has undergone no wear yet, such upper roller may be allowed to wear a considerable amount without loosing the'beneiit of this regular drive., t Y

The removable ordetachable gear 14 at the end of shaft may easily be replaced. Its number of teeth determines the speed ratio of rollers 2 and 9 of the press.

'Ihe intermediate gear member 49 borne by a stub shaft on a. semi-circular plate`49"rotat able on shaft 39 and secured by means of slots and 56 and nuts 57 and 58 takes care of the driving (Figure 2). The changes inthe angular speed of the roller are obtained by the provision of limited weight andeasily fitted gears of which it is not expensive to have a set in stock. .Practically it is suflicient Vto have a set of gears which differ in their numbers'of teeth by two successively. WithV a seven gear set it is possible'to obtainthe theoretical speeds for the upper roller notwithstanding a wear amounting to 14 centimeters on the diameter of such roller.

As gears 46 and 47 apply on upper roller 2 an upward stress proportional to the resistance of the press -to operation it follows that, by such driving arrangement, the press takes Vupthe material under treatment most easily Y and that there is much less liability fortlie wool to pack or accumulate in advance of the rollers. Y

Whatever the position of the upper roller may be in the limits of practice, 'the speed of the latter as results from being driven by y the intermediate members remains 'always over-thickness.

position of elevation of the former.

constant but, considering the moment when said upper roller rises or descends, the speed is not absolutely constant. v

As regards the pressure between both rollers, it diminishes when roller 2 has to y rise on account of a thicker Vsheet being fed,

the Cardan joint is driven by bevel pinion 26 and a bevel gear 27, the latter being keyed on shaft 2S of the gear box. Y Figures 5 and 6 show that both worm wheel and wormmay be rreplaced by two bevel gears 29 and 30. Gear 30 is driven by key 21 iixed on shaft 19". The latter is driven by means of spur gears 31 and 32, bevel pinion 26, bevel gear 27 and the gear box 7".

In the two above mentioned cases (Figures 3 and 4, 5 and' 6) an angulary speed of the upper roller 2a or 2b, completely independent of the lift of said roller, is obtained. f

In the paticular case of Figure 7, a worm V13b is fixed in position by being keyed on its vertical driving shaft. Suchv arrangementv gives an approximate solution, inasmuch as every vertical displacement of the upper roller 2b causes a slight variationin its movement of rotation, said acting, then, .as a rack Vwith respect to the worm wheel 17 b.

In the cases of Figures 3v and 4 (movable worm) and Figures 5 and 6 (movable bevel gear), the pressure between the two rollers is entirely independent of the upwardA or downward movement of the upper roller 2a. or 2b; the vertical stress between the worm 18 and` Worm wheel 17, and between the bevel gears 29 and 430, being cancelled by the reaction of the casing 20 fixed to the said upper roller. n

In the' arrangement of Figure 7 (fixed worm), the pressure between the two rollers diminishes when the upper roller 2b is about to rise; so that here again there is a reduction ofthe likelihood of failure ofthe press to operate through kclogging of the rollers. In allthe above mentioned embodiments the number of the exchangeable pinion, or the position at which the handle ofthe gear box must be set may, for instance, be indicated by means of a pointer 36 moved across an indexed dialv 37 by means of a rod 38 connected to the shaft ofthe upper rollers 2, 2a and 2b. It need not be mentioned that, instead of being positioned between the upper and lower rollers, the intermediate members lmay be interposed between the upper roller and the main drive shaft 39 of the press or between each of the rollers and said shaft 39. Inasmuch as the number of revolutions of the latter, for instance in the presses of washing machines, is generally tenfold that of the lower roller which it drives through pinions 40 and 41, it is easier to use smallsized pinions as intermediate members.

Having now particularly ascertained and described the nature of my said invention as well as the manner in which the same is to be performed, I declare that what I claim is:

In a press for squeezing textile or other materials, upper and lower pressing rollers between which the materiall is fed by the pressure of the rollers, means for applying power to the lower roller, intermediary gear trains imparting rotary motion to the upper roller substantially independently of lift of that roller due to passage of a portion of the material of abnormal thickness between the rollers, the gear elements of said intermediary gear trains transmitting power to the upper roller being located in a plane substantially horizontal with the axis of the upperrollerga main drive shaft, and a con nection between the same and the lower roller, the rotation of the upper roller being effected by said shaft through the intermediary gear trains; an auxiliary shaft whereon the gears Y ofthe intermediary gear trains which impart rotary motion to the upper roller are mounted for rotation independently of each other; a pinion fixed for rotation with saidv auxiliaryshaft; a plate mounted for angular adjustment at one side of the press; means which impart rotary motion to the upper f.

roller, thereby to permit the upper roller to rise a reasonable distance without separation of the meshing gears.

In testimony whereof I aiiix my signature.

EDMOND LOUCHET.
