Application filed October 6, 1910. Serial No. 585,632.

Be it known that 1, PAUL Pnrmr, a subject of the King of Saxony, residing at '13 Lindenstrasse, Heidenheim onthe Brenz,

Germany, have invented certain new and useful Improvements in Paper-Making Machines; and I do hereby declare the following to be afull, clear, and exact description of the invention.

This invention has for its object an arrangement in longitudinal straining cloth paper-making machines, which enables the .cloth to be adjusted to various inclinations,

without the height of ,the' breast-roll end of the cloth being thereby altered.

Several forms of construction of the improved arrangement are shown in the accompanying drawings, in which v Figure 1 is a side elevation of a paper making machine embodying my invention. Figs. 2, 3, 4, and 5 are similar views of machines of modified construction.

In the machine illustrated in Fig. 1 only the inclination of the shake-frame a is variable, while the inclination of the suction part b remain-s constant. The standards Z of the suction part are made so as to be telescopically extensible. Toothed wheels g, I which are operated by means of a crank in,

a shaft and pairs of bevel wheels, engage with rack-bars (not shown), which? are firmly connected with the displaceable hoodshaped upper parts of the standards 1 in such away, that by rotating the crank 70,

the suction part is raised vertically parallel with itself. An arm h is cast on each of the two right hand standards. The ends of the rails or girders 0 are pivoted to these two arms 71, which girders are pivotal on bolts e and carry by the intermediary of standards p and f the bars of the shakeframe; the standard or bracket 1 is pivoted in the ordinary way, so that it allows of the necessary shaking movement of the cloth. By vertically displacing the suction part, the inclination of the shake-frame is altered.

' The suction part is given such an inclination that when the shake-frame is adjusted to the most inclined position which it may be desired to give it while the machine is in operation, the part of the cloth lying on the shake-frame and that lying on the suction frame are approximately in-the same direction and lie in one plane. If the suction part were tolie at a lesser inclination or horizontally when the shake-frame was confrom the first suction boxes and from the last rollers of the shake-frame. Fig. 1 showsthe machine with the shake-frame adjusted to the greatest inclination, while the position of the cloth when the make-frame.

is lying horizontally is shown in dotted lines in F i 1.

In the form of construction shown in Fig. 2 the standards Z carrying both the .ends of the girders adjacent 'to the squeezing press are connected to-the lower end of a screwed spindle q vertically mounted in a standard 'm, the upper end of which screwed spindle is formed as a worm-wheel n. By turning the crank g the worm wheel 72. is rotated and thereby the spindle q raised and the inclination of the cloth altered.

In the form of constructionshown in Fig.

8 the pair of girders c is arranged above the straining cloth. The suction part is carried by standards Z rigidly mounted on the girders. The shakeframe a? is suspended from the girders by means of flexible steel bands 72?, which allow of the necessary shaking motion. 1

In the forms of construction shown in Figs. 4 and5, the rollers of the shake-frame and the suction boxes are supported by a single continuous pair of rails s, which in. Fig. lare stiffened by struts 14,0, w and in 5'by a truss frame a, o, w, in such a waythat the flexion load may be freely carried by the rails and the arrangement of standards (pand Zof-Fig. 1) is superfluous.

In the form of construction shown in Fig. 5, the breast-roll end of the pair of rails is suspended on two pillars or standards f of purpose that because of the breast-roll end of the shake-frame not being displaced in height when the inclination of the cloth or apron is changed, the flow of paper pulp on PatentedDee. 13, 1910.; I

siderably inclined, the cloth in consequence of the tension imparted to it would tend to I adjust itself in a straight line and lift away the cloth is in no way afl'ected by changing the inclination so that the inclination of the cloth may be altered within wide limits even during the working, and thus, without the slightest loss of time, the inclination of the cloth, which at the moment appears to be the most suitable one, may be ascertained by testing during the working of'the machine, which is impossible in the ordinary apparatus .in which, when the inclination'of the cloth .is altered, the os'ition of the breastroll end of the shake-. ame is also altered in height.

clined suction frame a normally inclined shake frame, a sub-frame extending from the breast roller end of the shake frame to the front end of the suction frame, said subframe being pivotally mounted at the breast roller end of the shake frame, means connecting with the suction frame for raising or lowering the endof the shake frame next to the suction frame, together with the whole suction frame, the plane of the two frames,

including in no position an angle of less than 180.

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

PAUL PRIEM.
