adapted to drive the grinding disks through the medium of the ropes or belts 33 which ride on thepulleys 3l.an'd 34 of the disksha-fts 21 and motor sliaft 35, respectively.
The driving ropes or belts 33 are .at all times kept under proper tensiomthrough the medium of take-up devices, of which there is one for each belt. Each of said devices consists .ofa grooved pulley 36 engaging with its respective driving rope and mount: ed on an arm 37- which swings loosely on a stud 38, and "has a tensioning weight39. The stud 33 is carried by a slide 40 which is mounted on' the slotted bar 41,,and said bar 41 is adjustablymounted through the medium of slotted arms 42 on the cross member 4 of the machine supporting frame. Each of the slides 40 is provided with a securing bolt 43 which engages with a slot of the bar 41 and is adapted for securing said slide in adjusted position.
In the application of the machine for grinding the, slitter knives of a paper machine the frame is rested upon the spreader 6 and guide roller 7 ofthe paper machine -as in that manner illustrated in Fig. 2. The emery disks 10 are then adjusted on their respective hangers tobring their grinding surfaces into contact with the cutting edges of the slitter knife 11, and such adjustment is then secured by the means heretofore stated. The motor 32 is then operated to rotate the disks 1O and simultaneously therewith a slitter knife being ground is turned through the medium of the shaft on which it is mounted. The hangers are then adjusted to remove the grinding disks when the machine is free to be moved bodily, by sliding along the guide roller and spreader, to bring the grinding disks to be disposed on opposite sides of the slitter knife 11 to be ground. The machine in its entirety 1 may be lifted from one paper machine and 50 placed on another as shown in Fig. 2, when the above-described operations may be again performed.
It is obvious that those skilled in the art may vary the details of construction and arrangement of parts without departing from the spirit of myinvention, and therefore I do not wish to be limited to such features ex ept as may be required by the claims.
What I claim is 1. In a grinding machine, the combination of a support; a hanger mounted on" said .support' and comprising a swingingly- -mounted on" said shaft; an-arm having a dove-tailed slidable connection with said bar; a journalbearing rotatably mounted on said arm, a shaft journaled in said bearing; a grinding element mounted on said shaft; and a motor connected to drive the shaft of said grinding element, substantially as described.
3. In a duplex grinding machine, the combination of a support; a shaft mounted on said support; a pair of hangers mounted'on said shaft; a pair of grinding disks mount-ed on said hangers; means for imparting universal adjustment to said grinding disks; a motor mounted on said vsupport; and driving connections between said motor and said grinding disks.
4. In a portable duplex grinding machine, the-combination of a rectangular frame; a shaft secured in hearings on said frame; a
pair of hangers swingingly mounted on said shaft; said hangers comp-rising each a bar having a dove-tailed guideway formed therein,'an arm having a-dove-t-ailed head slidably mounted within said guideway, an
adjusting screw mounted on said bar and connected with said arm for adjusting the same, and a bolt passing through said arm and bar for securing the arm in different set positions; journal bearings adjustably mounted on the lower ends of said hangers;
grinding disks journaled on said journal bearings; and amotor mounted on the frame and having driving connect-ions with said grinding disks.
In testimony whereof, I aflix my signature, in presence of two witnesses.
