c. B. MAXSON COUNTING MACHINE Jan. 5, 1932.

Filed April 29, 1926 Patented Jan. 5. 1932 UNITED STATES PATENT} OFFICE CHARLES B. MAISON, OF WESTERLY, RHODE ISLAND, ASSIGNOR OF ONE-HALF TO JULIAN W. MAXSON, OI WEBTERLY, RHODE ISLAND COUNTING MACHINE Application filed April 29, um. Serial No. 105,505;

The present invention relates to counting machines, and more particularly to machines for countin sheets of paper or the like in a stack or pile of the sheets.

5 .The chief object of the invention is to improve upon machines of the above-described character. Other objects will appear hereinafter and will be particularly pointed out in the appended claims.

The invention will be explained in connection with the accompanying drawings, in

which Fig. 1 is a diagrammatic view illustrating the invention in its preferred form;

Fig. 2 is a continuation of Fig. 1, and Fig. 3 is a view of a modification of Fig. 1.

The invention is illustrated in its preferred form as applied to the counting of sheets of paper in a stack or pile 2. The sheets4 are first fed, in lapped relation, from beneath the pile in any well-known manner, as, for example, by the mechanism illustrated and described in Patent No. 690,167 granted December 31, 1901. In the beginning, the speed of travel of the sheets in the table 5 is comparatively low. As soon as the head 6 of each sheet reaches the bite of two feed rolls 8 and 10, these rolls increase the speed of travel of the sheets. At this increased speed, but preferably still in so lapping relation, the sheets are fed by tapes v 12 into a lay-boy 14.

Prior to the sheets reaching the rolls 8 and 10, each sheet is engaged by a roll 16.

The roll 16 is pivoted to rotate at one end 17 of a link or links 18, the other end of which is pivoted at 20. The link or links 18 are thus free to pivot in opposite directions about the point 20, permitting oscillation of the roll 16. The roll 16 is continuously driven from any desired source, as from a motor 22 that drives a shaft, not shown, the

axis of which coincides with the pivot and that is connected with the roll 16 by suitable gearing The speed of travel of the periphery of the roll 16 is somewhere between the low speed and the high speed of travel of the sheets. If the sheets are fed out from the stock 2 at a speed of fifty feet per minute, for example, and if this speed is increased by the rolls 8 and 10 to 150 feet per minute, it is convenient to have-the surface speed of the roll 16 at about feet per minute.

When the roll 16 is first engaged by a sheet, therefore, it is traveling much faster than the sheet. Assuming that the roll is rotating in the direction of the arrow, it will swing over to the left about the pivot 20,

and it will remain at its extreme position to the left, just barely out of contact with the sheet. When the speed of the sheet is increased, on the other hand, it will be traveling faster than the surface speed of the roll, and the latter will then swing over to the right. The roll will thus swing back and forth about the pivot 20 once for each sheet that is fed forward out of the stock 2 and into the lay-boy 14. To count the number of sheets so fed, therefore, all that is necessary is to count the number of swings of the roll 16. A convenient construction com rises an arm 26 that is fast to the link. or linlis 18, so as to .swing therewith, and that is connected by a lever 28 to a counter 30.

The counter 30 thus counts the number of changes in the speed of travel of the sheets 4 or whatever other traveling means is engaged by the traveling periphery of the roll 16. The invention is therefore adapted to wider uses than to counting the number of overlapping sheets illustrated in Fig. 1. In Fig. 3 the invention is shown applied to the counting of sheets 32 that are fed in'spaced-apart relation at 34 over high-speed tapes 36. Each sheet 32 will cause the roll 16 to swing to the right, and the roll 16 will be maintained in its right-hand position until the sheet has passed the point 3 1. It will then swing back to the illustrated position. But to actuate the counter, it is necessary to swing the roll 16 beyond the illustrated position, to the left. This may readily be efi'ected in any desired way, as by having the roll 16 engage a roll 38, rotating in the opposite direction. Assuming that the sheets 32 are fed at the rate of feet per minute, and the periphery of the roll 16 at 100 feet per minute, as in the case of Fig. 1, the surface speed of the roll 38 may be 50 feet per minute. The roll 38, will, of course, be stationed to one side of the tapes 36, so as not to interfere with the travel of the sheets 32.

Other modifications, too, will readily occur to persons skilled in the art, and all such are considered to fall within the spirit and scope of the invention, as defined in the appended claims.
