SAW FOR CUTTING PAPER ROLLS.

Application filed. October 30, 1922, Serial No. 597,730. Renewed March 14, 1925.

T 0 all whom it may concern:

Be it known that I, WILLIAM B. GILES, citizen of the United States, residing at Park Place, in the county of Harris and State of Texas, have invented certain new and useful Improvements in Saws for Cutting Paper Rolls, of which the following is a specification.

This invention relates to new and useful improvements in a saw for cutting paper rolls.

One object of the invention is to provide a saw of the character described whereby rolls of paper may be cut into sections of -f any desired length.

Another object of the invention is to provide a device of the character described whereby the roll of paper may be slowly turned automatically and gradually fed to the saw manually.

A further feature of the invention resides in the provision of a device of the character described so constructed that the roll to be cut may be easily mounted for the application of the saw thereto, as well as easily adjusted on its mounting.

A still further feature of the invention resides in the provision of'a simple and efiicient paper roll saw which may be cheaply and easily constructed and readily kept in condition for efficient use.

With the above and other objects in view the invention has particular relation to certain novel features of construction, operation and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying drawings, wherein Figure 1 shows a side view of the device partly in section.

Figure 2 shows an end view thereof partly in section, on the line 2-2 of Figure 1.

Figure 3 shows an end view of the shaft for carrying the paper roll and the bearing therefor and,

Figure 4C shows a side view of the opposite end of said shaft mounted in its bearing.

In the drawings, the numeral 1 designates the frame work which preferably consists of a table and supporting legs therefor. The numeral 2 designates a transverse drive shaft which is mounted in suitable bearings carried by the frame work and one end of which has the drive pulley 3 fixed thereon. The other end of this shaft has the large pulley fixed on it which is alined with a similar pulley 5. This last mentioned pulley rotates on a suitable spindle 6 which is carried by the standards 7, upstanding from the frame work. A band saw 8 operates over the pulleys 4 and 5. The frame work carries two transverse tracks 9, 9 mounted thereon and spaced apart, and whose facing sides have lengthwise grooves to receive the edges of the slide 10. This slide has along angle iron 11 bolted thereto and depending from which there is a lug 12. A crank 13 works in a bearing in said lug and is held against lengthwise movement relative thereto by means of the fixed collars 14, 14: fastened on the shaft on opposite sides of the lug. The inner end of the crank is threaded through a tapped hole in the frame work and its outer end is formed into the usual handle 15 by means of which it may be turned. By the operation of this crank the slide 10 may be adjusted toward and from the framework. The numeral 16 designates the roll carrying shaft. One end of this shaft works between the fingers 17, 17 of the hearing 18 which is mounted on the corresponding end of the angle iron 11. Said end of this shaft has a deep annular groove 19 and there is an adjusting rod 20 which is threaded through the bearing 18 and which has a fixed disc 21 thereon whose margin works in the groove 19. The shaft 20 has a grip handle22 by means of which it may be turned and the shaft thus adjusted lengthwise. Provision is thus made for nice adjustment of the paper roll 28 relativeto the saw. This roll is wound on a split mandrel 24 through which the shaft 16 extends, and the mandrel is tightened in the roll by expanding the same through the instrumentality of cone shaped collars 25 which are fitted on the shaft and whose small ends fit within. the corresponding ends of the mandrel. These collars are keyed to the shaft by means of keys 26 providing for their adjustment and the adjustment of the paper roll on said shaft. The other end of the shaft 16 is rotatable in a bearing member 27 which is mounted on the other end of the angle iron 11 and which is bifurcated forming the lugs 28, 28 spaced apart and between which the screw gear 29 works. The end of the shaft 16 works through hearings in the lugs 28, 28 and the gear 29 is splined thereon. The shaft bearings in lugs are it is desired to remove the roh on the opposite end of said shaft may be lifted from the bearing- 18 and the exchange made.

I There is a transverse shaft mounted at one end in the bearing, 31 and at its other end in the bearing 27. This shaft is driven from theshaft 2 through the belt 32 which operates over the pulleys 3S, mounted respectively on the shafts 2 and 30. There is a worm gear 3d splined on the shaft 30 and in mesh with the gear 29 through which said last mentioned gear is driven in the direction indicated by the arrow in Figure 2.. .Vhen the gear. 8% is in driving relation with the gearv 29 the former-abuts against the bearing'27 and is held in said driving relation. Then it is desired to disconnect said gears the shaft 16 may be manually turned forwardly, in the direction indicated by the arrow in Figure 2'and this will operate to slide the gear 34 inwardly on the shaft30 and out of mesh with the gear r29.

In operation the saw is driven through the. shaft 2 at the required rate of speed and the shaft16 and the roll of paper mounted thereon is automatically driven through the belt 32 at a slower rate of speed. The paper rollis, adjusted to the desired place on the shaft 16 and is fed to the saw by slowly turning the crank 13 until the roll is severed. The collars 25 are then released and the roll adjusted on the shaft 16 to the proper place for cutting another section. An accurate adjustment, however of the roll is made through the adjusting rod 20 and the operation is repeated until the roll is cut into the required number of sections.
