Specification of Letters Patent.
Patented Nov. 28, 1905.
Application filed April 16, Serial N0. 203.4:7L
To all whom it may concern:
Be it known that I, BERNHARD SOHNITZER,
a subject of the King of Wiirtemberg, residing at Wildbad, in the Kingdom of Wi'irtemberg, Germany, have invented certain new and useful Improvements in Polishing and Grinding Mechanism for Paper Machine Press-Rollers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to polishing and grinding mechanism for paper-machine pressrollers.
The rollers of paper-machines provided with rubber, paper, and felt covers are subject to an irregular wear, and in order to again insure good work they are obliged to be leveled and ground true. I
The object of the present invention consists in an apparatus for grinding the pressrollers which is characterized by the arrangement that the rollers during the runnin of the paper-machine are kept true by aid of this apparatus, and therefore fit together most exactly and can be polished thereby, so that troublesome dismounting of the rollers is avoided, and the material passing between the rollers always arrives from the moist part to the dry part equally cleared of water over the whole track, which is very advantageous for the product, both in the qualitative and the quantitative sense.
In the accompanying drawings, Figure 1 is a side elevation. Fig. 2 is a top plan. Fig. 3 is an end view, and Fig. 4 is a section on the line A B of Fig. 2.
The device illustrated in the drawings consists of a longitudinally-slotted tube a, which is supported in bearings 6 upon the machineframe, and of a screw-spindle 0, arranged in this aforesaid tube. Upon the screw-spindle a support d can be adjusted by revolving the crank 6, attached to the screw-spindle, whereby the said support is displaced longitudinally by means of a neck f, passing through the slot of the tube a, which forms a guide for the sliding block or collar g, embracing the tube. On this slide 9 there is pivoted, by means of the ears 1), contact-shoe h, of suitable shape and provided with the requisite polishing or grinding material 0, (emery or the like.) The tube a can be turned by means of a lever Z, arranged in the head 7c, the
head 76 of course being fastened, by means of screws or otherwise, to the tubea. Owing to the revolution of the tube a the contact-shoe, pivotally connected with the slide is correspondingly approached to the ro er to be ground or pressed with greater or less firmness thereu on, while the same is also displaced in the ongitudinal direction by turning the crank e. The grinding material is preferably secured in single sheets upon the contact-shoe in such a manner that the worn-out sheets can be readily removed. The method of displacement of the contact-shoe and the method of pressing it upon the roller may of course be carried into effect in various ways. As will be obvious herefrom, there may be effected, bymeans of the said shoe, a grinding of the one roll and at the same time the immediate control of the regular contact of both rolls. This constitutes a very important advantage of the present over previous methods even without considering the hitherto tedious and troublesome dismounting of the rolls, because even when the rolls are equalized in the most exact manner upon the lathe they still had not throughout their length exactly the same spacing, because wet pressing-rollers, even in their covered part, wore down irregularly, so that an absolutely parallel adjustment and exact air-tight contact was only attainable with great difficulty.
What I claim, and desire to secure by Letters Patent, is
1. A roll polishing and grinding device comprising a feed-screw journaled in suitable bearings, a traveling nut mounted on the screw, a guide extending parallel to the screw, a slide secured to the nut and movable u on the guide, a contact-shoe pivoted to the slide eccentric to the feed-screw, means for rotating the screw, and means for revolving the slide about the axis of the screw.
2. A roll polishing and grinding device comprising a feed-screw journaled in suitable bearings, a traveling nut mounted on the screw, a tubular guide inclosing the screw, a slide secured to the nut and movable on the guide, a contact-shoe pivoted to the guide, means for rotating the screw to adjust the slide longitudinally of the guide, and means for revolving the slide about the screw to adjust the position of theshoe laterally.
3. A roll polishing and grinding device comprising the combination, with a roll, of a feed-screw extending parallel thereto and journaled in suitable bearings, a nut threaded shoe toward and retract the same from the. IO on the screw, a slotted tubular guide inclosroll.
