PAPER-EDGING MACHINE.

Application filed April 16, 1924. Serial No. 706,953.

I '0 all who"; it may concern:

Be it known that I. BEN S. OLSON, a citizenof the United States. residing at St. Toseph, in the county of Buchanan and State of Missouri, have invented certain new and useful Improvements in Paper-Edging lilachines, of which the'following is a specifieation.

This invention relates to aper edging machines and it consists in tlie novel features hereinafter described and claimed.

An object of the invention is to provide a machine of simple and durable structural arrangen'ient having means and features adapted to operate upon a. stark of paper to produce ragged edges or deeollated edges upon the sheets.

\Vith the above object in view, the ma chine comprises a stand or frame having a shaft journaled thereon, there being provided upon the shaft one or more cutting elements. Pneumatic means is arranged adjacent the said cutting element and is adapted to receive the chips or particles which are removed from the stack of paper and convey the same to a distant point.

A frame is pivoted upon the stand under each of the cutting elements and standards are movably mounted upon the same frames. Means are provided for manually moving the standards along the frame. Stack holdcrs are slidably mounted for vertical movement upon the standards and manually operable means are provided for shifting the stack holders vertically along the standards and vertically and transversely of the edge cutting elements.

In the accompanying drawings,

Figure 1 is a side elevation of-the machine for producing decollated edged paper.

Figure 2 is a transverse sectional view of the machine, i

Figure 3 is a fragmentary detail plan view of a pivoted frame used upon the machine,

Figure 4 is an enlarged fragmentary plan view, with parts in section of means for shifting the. standards upon the frame.

As illustrated in the accompanying drawing. the machine for producing ragged dges or deeollatededges upon pieces of paper consists of a frame having a shaft 2 journale-d thereon, the cutting elements 3 are mounted upon the shaft 2. As shown in the said figure, there are two units of the machine mounted upon the same frame.

blOCkl and a base block 5.

These units are alike with the exception that the cutting elements 3 upon one of the units is longer or larger than the cutting elements 3 upon the other units. The units located at the right hand end of the frame in said figure is intended to beused for cutting the edges of relatively small pieces of paper as for instance, a sheet adapted to be used for making envelopes. The unit illustrated at the left hand end of the frame in said figure is intended to be used for cutting the edges of relatively large sheets of paper as for instance, writing paper or sheets which are intended to be folded and placed within the envelope. A description of one unit will answer for both. Each unit includes a base These blocks are spaced from each other and are mounted upon the stand 1. A frame 6 is pivotally mounted upon the block 4 and includes side shafts or rails 7 and 8. the shaft 8 being )rovided with teeth 9 which are cut into the ody of the shaft upon the side thereof and as best shown in Figure 3 of the drawings. .The frame also includes a cross bar 9 which connects the ends of the shafts 7 and 8 together. the block 5.' A pin 10 may be passed through the bar 9 and lodged in the block 5 whereby the frame 6 is held at a fixed gosition with relation to the blocks 1 and 5. k paced collars 11 are slidably mounted upon the shaft 8 and similar collars 12 are slidably mounted upon the shaft 7. Vertically disposed standards 13 are mounted upon the collars 11 and brace rods lat conneet'the standards 13 with the collars 12 as best shown in Figure 2 of the drawings. A platform 15 is slidably mounted upon the standards 13 and tubular members 16 are mouutedat the corner portions of the plat-' form 15 and slidably receive the standards 13. One of the tubular members 16 is longitudinally slotted as at 17 and the standard 18 which is received in the said slotted tubular member is provided with a series of teeth 18. A bracket 19 is fixed to the said slotted tubular member 16 and a shaft 20 is journaled upon the said bracket. A hand wheel 21 is mounted at the outer end of the shaft 20 and a gear wheel 22 is fixed to the inner end of the said shaft 20. The gear wheel 22-'mesl1es with the rack teeth .18. Therefore it will be seen that as the shaft 20 is rotated the tubular members 16 and the platform 15 are raised or lowered upon the The cross bar 9 normally rests upon standards 13. The tubular members 16 are connected together by a cross bar 23 and a shaft 24 is journaled upon the said cross bar. A hand wheel 25 is carried at the outer end of the-shaft 24.

A shaft 26 passes through the platform 15 and is journaled therein and carries at its lower end a gear wheel 27 which meshes with the teeth 9 in the shaft 8. A beveled pinion 28 is splined upon the shaft 26 and meshes with a beveled pinion 29 which is mounted upon the shaft 24. Therefore it will be seen that when the shaft 24 is rotated by using the hand Wheel 25 rotary movement is transmitted to the shaft 26 and gear wheel 27 and in that the teeth of the gear wheel 27 are in mesh with the teeth of the shaft 9, the standards 13 and the platform 15 will be moved longitudinally of the shafts 7 and 8 and longitudinally along the edge cutting elements 3. The head plate 30 is mounted upon the upper ends of the tubular members 16 and a clamp screw 31 is threaded through the said plate. A clamp plate 32 is carried at the lower end of the screw 31 and a hand wheel 33 is mounted upon the upper end of said screw. In practice a stack of paper is placed upon the platform 15 and the screw bolt 31 is turned whereby the paper is clamped between the plate 32 and the said platform. At the time that the stack of paper is placed upon the platform, the pin 10 is removed and the frame 6 is swung from over the stand 1. When the stack of paper is placed on the platform and clamped the frame 6 is'swung back over the stand 1 and secured by inserting a pin 10 through the bar- 9. The shaft 2 is rotated by a belt 34 from a motor By manipulating the hand wheel 25. the platform is raised and lowered with relation to the edge cutting element 3 and at the same time or subsequently the hand wheel I 25 may be manipulated whereby the platform and the stack of paper moves longitudinally along the edge cutting element 3. The edge cutting element 3 includes a number of radially disposed blades 34 and these blades cut into the side of the stack of paper and produce the ragged edges upon the sheets of the stackwhereby the sheets are decollated. For swinging the frame 6 and the parts thereof with relation to the stand 1 a handle 35 which is attached to one of the tubular members 16 may be used. A conduit or pipe 36 has its receiving end disposed opposite the cutting elements 3 and is connected with a horizontal pipe 37 which is connected with a suction fan 38. The shaft of the fan 38 is operatively connected with the shaft2by means of a belt 39. Therefore, the particles of the paper which are removed from the edges of the sheets and from the side of the stack of sheets are turned by the cutting element into the upper end of the conduit 36 as they gravitate down into the pipe 37 The suction draft which is created by the fan 38 carries the said particles from under the stand 1 and may discharge them at any desired point.

Having described the invention, what is claimed is 1- l. A machine for decollating paper comprising a frame, standards slidably mounted upon the frame, manually operable means for moving the standards along the frame, a platform mounted for vertical movement upon the standards, means carried by the platform and adapted to be manually operated for raising and lowering the platform along the standards, a cutting element journaled for rotation above the platform and having a series of radially disposed cutting blades and means for securing a stack of sheets upon the platform.
