. .MEANS mn CONTROLLING THE PULP- STRAlNER DRUMS 0F PAPER-MAKING MACHINES."

To an" why???) it may concern/r Be it known that I, MiARCELLAMORT, a citizen\ of France, residing at Paris, in the said Republic, have invented new and useful Improvements in Means for Oo'ntrolling'the Pulp-Strainer Drums of Paper Making Ma.- chines, (for which a" French patent, No. 362,996,..of'Februai'y 5, 1906, has been Obtained,) of which the following is a specificat1on.

This invention relates to improved means for controlling the pulp-strainer drums of paper-making machines, whereby two movements can be communicated to them, one-a shaking or shogging movement, which im' parts to the drum a displacement of afew millimeters in the vertical direction, the other a rotary inovement a consequence of the first, which imparts to the drum a very slow rotary movement of only a few revolutions per minute.

The annexed drawings represent by way of example, Figure 1, an end view, partly broken away, of an ordinary pulp-strainer drum of a paper-making machine provided with the controlling means forming the sub ject of the esent invention; Fig.2, an elevation of t e same, partly in longitudinal section, taken on the line as y of Fig. 1'; Fig. 3, a plan of the same, partly broken away; and Fig. 4 a detail of one of the devices serving for working the machine.

The same reference-numerals indicate like parts throughout the figures.

1 is a pul -strainer drum consisting, as usual, of a j ac et or casing 2, supported at its ends by two metal heads 3 4, each having a flange 5 6, similar to the rim of a pulley that is to say, each is capable of receiving a strap 7 8, placed as shown at 9 1O 11, and the points of attachment 11 12 of which are constituted by means of feet forming grippers.

' At'9 13 the straps are connected to theends of two iron arms 14 15, both of which are keyed on a shaft 16. By causing the ends of these arms 14 15, pivoted on the shaft rection. .5

16, to rise and fall a reciprocating movement is impartedto the druml in the vertical di- This movement is obtained in a continuous and rapid manner b employing a third lever v17, one end of whic 'iskeyed to the shaft 16, while its other or free end serves as a fulcrum or hearing for a vertical connecing-rod, 18, which is itself connected at its Specification of Letters Patent.

centric 20, forming part of a driving-shaft 2-1, which is set in motion by means of a belt passing over a stepped pulley 22, therebyenvabling the speed to be'varied at will, soas to obtain a' number, also variable, of shakings or shoggings of the drum- These shakings or shoggings are rendered sharper'"'and more energetic by the addition on each side of the drum of metallic stops or abutments 23,

placed immediately below each strap. As these stops or abutments are fixed and as the straps are capable of extension ,the feet 1 1 12 are not fixed, but are each connected to a' screw-rod 25 26, capable of being raised or loweredby' means of a hand-wheel 27 28, forming a nut[ The travel of the drum can therefore be regulated by causing it to fall from a greater or less height back onto the stops or abutments, thereby obtaining all the desired effects-viz., beatingswithout shock, beatings with shock, strong or weak, or even immobilityr The rotary movement of the drum is effected intermittently each time this latter is raised by the two straps. It is, however, the consequence of this rising movement and can, in fact,,only take place as long as the straps are drawn by one end only, because if they were drawn by both the r ends the drum would always fall back to the same place and there would be no rotary movement. This movement is, moreover, proportional to the-' necting-rod 18 by bolts 30 31. At its upper end the connecting-rod 18 is jointed to the lever 17 by means of a hemispherical brass piece 34,, traversed by the comiectingrod,

which is screw-threaded at its end and is held by means of a nut and a lock-nut. The piece '34 rests in a recess formed in the end of the lever 17, which is bored to allow the connecting-rod 18 to pass through.

The shaft 21 is carried in two )lummer blocks, one of which is placed on the side at 47 and carries two pairs ofbearing-blocks fixed on the two faces of the frame 35 at 36 37 38 39. The other, also fixed on the frame, sustains the displacements of the shaft throu 'h the intervention of the rings 40 and 41.

The shattll may be placed in the direction of the axis 42 43 or in the direction of the "axis 44 45. In this case, it is carried in two plummer-blocks resting on iron chairs.

When two strainers are arranged tandem, the shaft 21 may be replaced by a shaft carrying two eccentrics at 20 and 46.

The annexed drawings represent other constitutive parts of: ordinary pulp-strainers for' paper-making machines; but as these arts do not in any way relate to the present invention they are not described herein and consequently are not numbered.

1- claim Means for controlling the pulp-strainer drums of paper-making machines, whereby two movements are communicated to them,

one a shaking 0r shogging movement which imparts to the drum a' displacement of a few millimeters in the vertical direction, the other a rotary movement which imparts to said drum :1 very slow rotary movement of only a few revolutions per minute, said means consisting of carrier-straps for the drum, one of the ends of which is fixed while the other is capable of receiving, at will, reciprocating movements of traction of variable amplitude, whereby the shakings or shoggings of the drum and, consequently, a slight rotary movement of this latter are efiected.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
