Description
J. A. DEWNE PAPER MAKING MACHINE Filed June 15 1925 Jmw Patented Apr. 2?, 'l iitia near Jenn nnvinfa, or
enonenn, on'ranio, oan'ana.
PAEERJ'EAKING maenmn. v i as Application filed .iune 15, was. Serial No. 37,209.
To all whom a may concern.-
Be it known that I, Jenn ALEXANDER Dnvnvn, residing at Thorold, in the county of Welland and Province of Ontario, Canada, have invented new and useful improvements in Paper-lhlaking lllaohmes, of which the fol lowing is a specification.
My invention relates to improvements in paper making machines, and the object of the invention is to devise simple and cheaply constructed means for preventing wire mesh carrying the paper stock cutting; into the emotion tops of the suction boxes longitudinally and it consists essentially of thearrangement and construction of parts as hereinafter more particularly explained.
Fig. 1 is a side elevation showing the wire mesh, its carrying rollers, suction hoxes and my device applies thereto.
Fig. 2 is a plan view of the parts shown in Fig. l.
in the drawings like characters oi re ference indicate corresponding parts in each figure. l
1 indicates a wire mesh in the form ol' an' endless hand upon wvhich the paper stock is distrihuted in the usual manner.
2 is a hrest roll and 3 is a couch roll.
4 are the suction boxes by which the superlluous moisture isdraw oil from the paper pulp as it passes t-hcreover.
5 is an idler roller driv n hy the wire mesh. The hrest and couch rollers 2 and $3 and idl r roller 5 arcv mounted according to the usual practice in hearings, which hearings I have not shown as they form no part of my invention.
6 is a roller-over which the lower-11in ot' the wire mesh passes. The shaft 7 of the roller (3 is pivotally mounted at one end as indicated at 8 (o-permit the roller to swing in a horizontal plane. V
9 is asprocket gear secured to the shaft of the idler roller 5.
10 is a sprocket gear mounted upon a shaft 11 carried in suitahle bearings (not a citizen of the United States,
18 in which is slidably carried a bearing 19 in which is journalled the opposite end of the shaft 7. V
20 is a link provided with an eye, 21 at one end carried upon the projecting end of the shaft 7 and connected at its opposite end to the crank pin 16.
It will be seen by this construction that the idler roller 5 being driven by the travel of the wire melsh 1, the worm 12 is revolved through the sprocket drive consisting of the sprocket gears 9 and 10 and sprocket chain 22, thereby driving the worm gear 13 carrying the free end of the shaft 7 alternately in opposite directions by means'of the connecting link 20 thereby swinging the f roller 6, slowly, which swinging movement of the roller guides the wire mesh 1 alternately laterally in opposite directions so that its line of travel longitudinally is alternately altered, so that it moves over the suction boxes in constantly changing positions so as to wear the surface f the suction hox evenly, preventing any grooving or cutting into the suction boxes by the wire travelling thereover constantly in the same position.
It will he understood that under ordinary conditions the tendency is for the longitudinal strands of the wire ,mesh to out fine transverse grooverin the Wooden tops of the suction boxeswhen these strands travel in an unchanging position. lVhen, however, they are moved laterally by my device, the effect is to eliminate any tendency to the formation oi these transverse grooves as the lateral movement of the longitudinal strands on the suction boxes wears away any wood which is tended to be left on each side of such grooves, thereby maintaining the surface of the suction box in a smooth even condition.
Although I have described a sprocket drive whereby my device is operated, it will of course he understood that any other drivin connection may be employed for achieving the same result.
.Vhat I claim as my invention is:
l. In a paper making machine. the con1- hinalion with stationary suction boxes and an endless wire mesh, the upper ply 0t 1 which travels over said boxes, of means driven by the lower plyto impart a continuous slow angular swinging movement to said lower ply, whereby said upper ply iscaused to reciprocate laterally in its longitudinal. travel over said boxes.
In a paper making machine, the combination with stationary suction boxes and an endless wire mesh, the upper ply of which travels over said boxes, of a horizontally oscillatory guide roller for the lower 1y, a worm gear driven by the latter, a era pin on said gear, and a crank actuated by said pin for oscillating said roller.
3. In a paper making machine, the combination with stationary suction boxes and an endless wire mesh, the upper ply of which travels over said boxes, of a horizontally oscillatory guide roller for the lower ply, a sprocket wheel driven by the latter, a worm on the shaft of said wheel, a horizontal worm gear driven by said worm and having a crank pin, and a crank actuated by said pin for oscillating said roller.
In testimony whereof I have hereunto afiixed my signature.
JOHN ALEXANDER DEVINE.
