FRANK E. SAEGKEB, OIE APPLETON, WISCONSIN, ASSIGNOR TO APPLE'ION MACHINE COMPANY, OF APPLETON, WISCONSIN.

PAPER-STOCK SI-IREDDER.

Application filed August 11, 1913.

To all whom it may concern:

Be it known that I, FRANK E. SAEGKER, a citizen of the United States, and resident of Appleton, in the county of Outagainie and State of lVisconsin, have invented certain new and useful Improvements in Paper- Stock Shredders; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention consists in what is herein particularly set forth with reference to the accompanying drawings and pointed out in the claims of this specification, its object being to provide a simple, economical, strong, durable and eflicient machine organized to eliminate friction on the stock fed to shedding saws thereof, whereby free travel of said stock is insured and clogging or bunchmg up of the same avoided, especial attention being called to a pair of driven shredding-rollers constituting parts of said machine and having disk elements thereof sidewise to the saws.

Figure 1 of the drawings represents a side elevation of one of my improved paperst-ock shredders having parts thereof broken away;

Fig. 2, a plan view of the same having parts thereof broken away;

Fig. 3, a sectional view of a portion of the machine indicated by line 3-3 in Figs. 2 and 4c, and

Fig. 4:, a sectional .view of a fragment of the machine indicated by line 1-4: in Figs. 1 and 3.

Referring by numerals to the drawings, 5 indicates'each of the side standards of the shredder-frame mounted on the axles 6 of the wheels 7 the shredder being preferably portable, and an electric motor 8, or some other description of motor may be employed as part of the machine. Arranged on upper cross-bars 9, 9, of the frame is a table 10 having side guards 10 for the stock, and the standards of said frame are provided with bearings for the journals of rollers 11, 12, upon which an endless apron conveyer '13 is trained to traverse the table. The bearings for the journals of the roller 11 are adjustable to provide for tension regulation of the conveyer apron and the frame-standards are also provided with bearings for an arbor 14 upon which the circular shredder-saws 15 of the machine are Specification of Letters Patent.

Serial No. 784,149.

Another pulley 19 is fast on the saw-arbor and a belt 20 connects this pulley with a pulley 21 fast on a shaft 22 for which the frame standards are provided with bearings, working-tension of the belt 20 being determined by an idler 23 carried by a hand'lever 24 having fulcrum connection with the crossbar 5) of the frame. Fast on the shaft 22 1s a spur-pinion 25 in mesh with a spur-wheel 26 fast on the journal of the apron-roller 12, and another spur-wheel 27 on the same jour nal is in 'mesh with a spur-pinion 28 fast on the arbor of a pulp-supporting roller 29 under the shredder saws, the latter spurpinion being also in mesh with a similar pinion 30 fast on the arbor of another pulpsupporting roller 31 companion to the one aforesaid. The frame-standards of the shredder are provided with bearings for the arbors of said pulp-supporting rollers, and fast on each of these rollers at suitable intervals apart are projecting disks 32 sidewise to the saws 15 that have a rasping action as they rotate to shred the stock fed thereto, by the aforesaid conveyer, over a ledger plate 33 in detachable connection with a crosspiece 3 1 of the frame.

Brackets 85 connected to the forward ends of the frame-standards are connected by a pintle-rod 36 engaging the knuckle-end of a semi-circular housing 37 for the saws.

Fast on the shaft 22 at the main drivingbelt side of the machine is a sprocket-wheel 38 connected by a link-belt 39 with a similar wheel 1-0 fast on a spindle 41 for which a bracket-end of the crossbar 9 is provided with a bearing. Another sprocketwheel 42, fast on the spindle a1, is connected by a linkbelt 13 with a similar wheel 14: fast on the arbor of a pressure roller 15 parallel to the apron-roller 12, said arbor being engaged with supporting arms -16. One of the arms is loose on the spindle 11 and the other arm is similarly disposed on a pivot-bolt 17 extending through another bracket-end of the crossbar 9. Shackled to the arms 46 are the upper ends of rods 18 similarly connected at their lower ends to cranks 49 fast on a shaft 50 for which the frame-standards are provided with bearings, and a cranked footlever 51 is fast on said shaft to enable the operator of the machine to vary the pressure of the roller 45 on the paper stock fed by the conveyer to the shredding-saws.

From the foregoing it will be understood that motion is transmitted from the driven saw-arbor to the forward apron-roller 12, the rollers 29, and 31, and the pressure-roller 45, when the idler 23 is in normal position over the belt 20, but when the handle end of the lever 24 is depressed said idler is lifted to stop the operation of the conveyer, pressure-roller and anti-frietion rollers.

It is noted that by the arangement of gearing, the saws 15 rotate at a much greater speed than. the pulp sru'iporting rollers 29 and 31, and thus the rollers serve substantially in the nature of a concave to provide for a maximum action of the pulp by the saws. At the same time the rollers are c011- tinuously rotat ahle and thus provide for a sweeping action of the saws over their entire peripheries between their disks 32 whereby the rollers are kept clean to pre vent possible clogging and at the same time the disks of the rollers project slightly between the saws to prevent clogging of pulp therebetwcen. As indicated more particularly by the arrows in Fig. 3 it is noted that the innermost roller rotates in a counter clockwise direction, while the outer roller rotates in a clockwise direction to thus pro- Gopies of this patent may be obtained for five cents each,

vide a maximum retention of the pulp in contact with the saws.

I claim:

1. In a paper stock shredding machine, the combination of a feeding mechanism, a driven arbor, a series of eircularshredding saws on the arbor to which the stock is fed, and a plurality of driven rollers disposed under the saws to engage the pulp and hold it against said saws.

2. In a paper stock shredding machine, the combination of a feeding mechanism, a driven arbor, a series of circular shredding saws on the arbor to which the stock is fed, a pair of rollers disposed under the saws for holding pulp thereadjaeent, and means for driving the rollers in opposite directions preventing passage of pulp therebetween.

3. In a paper stock shredding machine, the combination of a feeding mechanism, a driven arbor, a series of circular shredding saws on the arbor to which the stock is fed, a plurality of driven rollers disposed under the saws, and disks on said rollers extend.- ing between the saws.

In testimony that I claim the foregoing I have hereunto set my hand at Appleton in the county of Outagamie and State of VVisconsin in the presence of two witnesses.
