all whom it may concern:

Be it known that I, SAMUEL M. LANGS'L'ON, a citizen of the United States, and a resident of Camden, inthe' colony of Camden and State of New Jersey, have invented a new and Improved Paper-Slider, of which the following is a full, clear, and exact description.

My improved machine is designed for cutting or slitting a strip of paper into a plurality of narrower strips and rewinding the narrower strips side by side upon a suitable reel. i The special feature of my machine cmthe present invention resides in the I employ for maintaining uniform surface strips during the entire rewinding o eration.

In my improve machine the reel upon which the strips are rcwound is disposed between two friction drums rotating in engagement with the lated material on the reel. The reel and the two drums are relatively movable so that as thef size of. the roll increases, the two fric-,

tion drums are spread apart and still maintain the same relationship to the. drums. these parts is re sisled so as to create the desired rubbing action on the material.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both the figures, and in which Figure l is an end view of a machine constructed in accordance with my invention; and .l 'ig. 2 is a side elevation of the machine viewed from the left-hand side of Fig. 1.

The roll of material slittcd or subdivided into a plurality of rolls of narrower material, may be supported in any suitable manner, as, for instance, upon standards 10 mounted adjacent the machine. The material is unwound from this roll and passes first through a tension device, thence past the cutters which subdivide the mate rial, and thence to the roll B, which latter is made up of a plurality of narrow rolls Z: arranged side by side upon the same shaft. The tcnsion-creating device and the cutters involve no special feature of my present invention and may be of any suitable character, although I ,referably use a row of cutter heads of substantially the form shown 1.

surface of the accumu- A-which is to be in my previous patent, Number 692,105, issued January 28, 1902, all arranged on the same shaft. The tension device, the cutters and the rewinding mechanism preferably are all mounted on the same frame, which latter may be of any desired form. As illustrated, the frame includes a base 11 and end standards or uprights 12, 12 spaced apart and supporting the several shafts which extend from one standard to the other. The specific tension device illustrated includes two parallel rollers 18 and 14, over both of which the paper passes, and a third roller 15 intermediate the two first-mentioned rollers and movable in respect thereto. The paper passes beneath the intermediate roller 15, and this roller is carried by two loosely pivoted arms 16. The weight of the roller 15 is supported by the paper, so as to maintain the desired tension on the paper. The paper then passes beneath a roller 17 and thence upwardly between the cutters to an upper roller 18. The cutters are mounted on two parallel shafts l9 and 20, which are rotated at the same speed by intermeshmg gears and the two cutters coijperate to subdivide the material into a plurality of sep arate strips, which pass over the roller 18. The rollers 13, 14, 15, 1'! and 18 are preferably merely idlers and are not positively driven.

The paper after passing from the roller 18 is delivered to my improved rewinding mechanism. The rewinding mechanism includes a spool or reel 20*, journaled at the upper and outer ends of twoparallel swing in arms 21, 21. The two arms are journa ed at their lower ends on a shaft 22, which latter is the machine. The spool or reel 20 comes at a slightly higher elevation than the cutting; mechanism, and is free to swing toward an from the latter, although such swinging is restricted by a friction device hereinafter described.

Adjacent the roller 18, which guides the paper from the cutters, is a friction drum 28, over which the pa er passes to the spool or reel 20, and this fi iction drum is so disposed that when the arms 21 are swung to one limiting position,

the spool or reel 20 will contact with the surface of the drum.

The drum is positively driven and its shaft.

the main drive shaft carries a drive pulley The shaft carries a gear wheel 30,

preferably comprises of'the machine and 29.

shown in dotted lines in Fig. 1, by means of which motion is transmitted to an idler 31 and thence to the two cutters in succession. The spool or reel 2O isdriven to wind the material-thereon, but its speed of rotation of course decreases as the roll increases in size. For rotating the reel, I provide said reel with a pinion 82 intermeshing with a gear wheel 83 jo urnaled on a stub shaft carried by one of the arms 21. On this same stub shaft is a small pulley 34 for receiving a driving belt. Adjacent to the stationary shaft 22 and parallel therewith, I provide a shaft 35, positively driven from the main drive shaft of the friction drum 28. A chain 36 and suitable sprocket wheels will serve for this purpose. The shaft carries a gear wheel 37 intermeshing with a the shaft 35,

' I provide the v shaft gear wheel 38 loosely mounted on the shaft 22 and rigidly secured to the gear wheel 38 is a pulley 39 in the plane of the pulley 34. A. crossed belt 40 connects these pn ys and drives the pulley 84 from the pulley 39. As' the arms 21 which carry the reel are journaled on the shaft 22, and as the gear wheel 38 and pulley 39 are loosely mounted on said shaft, it is evident that the swinging of the shaft does not interfere with the positive driving of the spool or reel. The belt 40 is loose, so that although it tendsto rotate the pulley'34 and the spool, yet it can slip and travel at a greater rate of speed than the spool as the roll of material on the spool increases in size. The friction drum 28 is positively driven at a uniform speed, as is also and the reel 20 is rotated in the reverse direction to the friction drum 28 and may rotate at a continually decreasing rate as the roll grows in size. The second friction drum 41 is of substantially the same size as the friction drum 28 and is also positively driven and is movable in respect to the reel. The friction drum 41 is carried a shaft 42 journaled at the outer ends of two parallel swinging arms 43, 43, which latter are keyed at their lower ends on the shaft 22. For driving the friction drum 41, 35 with a gear wheel 44 mesliin with a gear wheel 45 loosely mounted on t e shaft 22. The gear wheel 45 has a s rocket wheel 46 rigidly secured thereto, ant this wheel carries a chain 47 extending over a s rocket wheel 48 mounted on a stub shaft a jacent the outer end of one of the arms 43. On the same stub shaft with the sprocket wheel 48 is a gear wheel 49 meshing with a gear wheel 50 on the shaft 42 of the drum. Thusas the arms 43 swing with the shaft 22 and this shaft has the sprocket wheel 46 loosely-mounted thereon, it. is evident that the position of the arms 43' doesnot in any way affect the positive driving of the drum.

I The shaft 22 has a small drum or disk 23 keyed thereto, ad acent each end, and the frame carries ltwo semi-circular clamping aws 24, 24. These aws are pivotally connected together and pivoted to the frame by a suitable pivot bolt 25, and at their upper ends they are provided with means for drawing them togetherto frictionally bind the drums 23. Each clamping jaw 24 is provided with an upwardly-extending terminal flange 25 and a screw bolt 26 extends through these two flanges. By tightening the hand wheel 27 on this bolt,the flanges may be drawn together and the jaws caused to clamp the drum 01' disk 28 with any desired degree of pressure. The drum 23 is locked to the shaft and serves to retard rotation of the latter in respect to the frame. As the jaws 24, 24 are carried by the frame, it is evidentthat the resistance tothe rotatlon of the shaft may be increased or decreased as desired.

The distances from the center of the shaft 22 to the centers of'the two friction drums and the center of the reel, are all substantially the same, and as the drum 28 is stationary and the reel'20 and the drum 41 are movable, it is evident that the relative positions of all three may be changed as the materialinereases on the reel. The material is held between the drums 28 and 41 by the frictional resistance to the movement of the arms 43, and the weight of the material is counterbalanced by a weight 51 carried by a downwardly-extending arm or branch 52 rigid with its corresponding arm 21. The counter-weights, as well as the driving mechanisms for the reel and for the drum, may be duplicated at each end of the machine, if de sired.

The material after being slitted or cut into separate strips passes over the friction drum 28 and to the reel 20. The reel tends to rotate slightly faster than the drum 28, so that the material is tightly wound, and, furthermore, the drum tightly presses the material against the reel due to the friction clutches on the arms 43. The drum 41 is pressed against the material at the opposite side of the reel. and rotates at a slightly greater speed than the rate of surface travel of the material on the reel, so as to continually rub the surface of the material and draw it tightly on to the roll and insure the firm and compact winding of said material. The shaft 22 is so positioned in respect to the drum 28, that when the material has accumulated to form a roll of the desired size, the reel is substantially directly above the shaft 22. During the accumulating of the roll, the latter has been moved laterally and upwardly, and as gravityresists an upward movement of the roll,g. it is evident that this aids the clamping aws 23in holding the roll firmly against the drum 28'. With the arms '21 extendin verticallyupward, when the roll .is completed, the operator may loosen members and swing the arms 1 a "-o downwardly-to bring the roll closely recent the floor. It may now be removed lfOHl the machine Without Iii-ting 5 and Without the necessity for any sp cial tackle or hoisting mechanism. T vnig thus described my invention, I
