This invention relates to a paper handling device, and has particular reference to a device for handling paper of the character used in wrapping fruit, and the like.

Fruit wraps for wrapping fruit are usually of very thin paper and are more or less inconvenient to handle. The fruit wraps, or paper for wrapping fruit, are-usually arranged in stacks from which they are individually removed when used. It is'very difficult toremove a single sheet of this thin paper from a stack or pile without rufiling or disturbing the order of the pile. 7

It is a general object of the invention to provide a device for retaining a stack' of fruit wraps, or the like,'in an orderly condition.

It is another object of the invention to provide a device of the character mentioned that retains a stack or pile of paper in a man ner so that an individual sheet of paper may be easily and quickly removed without shifting or creasing the remaining sheets of paper.

a It is another object of the invention to provide a paper handling device of the character mentioned that is automatic in its operation and'that does'not require adjustment or setting as the paper is used of removed.

It is'another object of the invention to provide a device of the character mentioned that may bereadily mounted on a typical paper carrier and that may be adjusted to engage the paper at variousdis'tances from its edge.

It is a further object of the invention to provide a device of the character mentioned that is sturdy in construction and simple and inexpensive of manufacture.

The various objects andfeatures of my invention may be best and more fully under stood from the followingdetailed description of a typical, preferred form of the invention, throughout which description reference will be had to the accompanying drawing, in which: i

Fig. 4 is a'vertical view taken as indicated by line H on Fig. 3, showing the device apart from the carrier. Fig. 5 is an enlarged horizontal detailed sectional view of one ofthe paper engaging needles, being a view taken substantially as indicated by line 5-5 on Fig. 3, and Fig. 6 is a transverse detailed sectional view taken as indicated by line 66 on Fig. 4.

i r The present inventionis capable of embodiment in forms for useon or in connection with various classesof paper containers or carriers. In the drawing I have illustrated a form of the invention particularly adapted for use on a typical container or box for holding-fruit wraps, or the like, it being understood that the invention is not to be taken as restricted-to the particular form or appli- 7o cation-illustrated, but that it is to be taken as including any features or modifications 7 that may fallwithinthe scope of the claims.

The paper container orcarrier C il1ustrated in the drawing maybe considered as being 1 constructed of wood, or the like, and is intended primarily to hold a stack ofifruit wraps P, or paper oflike character. The carrier C may consist of a bottom 10, spaced sides 11, and an end or back 12. The-fo'rward end and top of the'carrier'C areopen so that the' paper P may be readily withdrawn. a l The paper holding device provided by this invention includes, generally, a bracket or body 13 adapted to bemounted on the back 7 12 of the carrier C, a shank or stem 14 slidably carried by the body 13, spacedarms 15 connected with the-stem 14 and disposed within the carrier 0, needles 16 on the arms 15 for engaging the paper P, and means 17 for maintaining the needles 16 in pressural engagement with the stack of paper P.

The bracket or body 13 is adapted to be mounted in a verticalposition on the outer side of. the back 12 of the paper container 0. The body 13 is the stationary elementof the device andslidably carries and guides the stem 14. In the form of the invention illustrated in the drawing, the body 13 is an elongated integral member having a central longitudinal opening 18. The opening 18 carries or guides the stem 14 for vertical movement and is preferably rectangular in cross sectional configuration. Mounting ears or flanges 19 project laterally from opposite sides of the body .13. The flanges 19 are adapted to seat against the back 12 0f the paper carrier and are provided with 'openings 20 for passing screws 21, or the like, for

attaching the bodyto the carrier G; The

body 13 is preferably mounted onthe carrier C so that its upper end is flush with or below I than the body 13 so that its upper end exp tends above the body when the-parts are in the full down position. The upward movement of the stem 14; may be limited by a set screw 24. A- longitudinal slot' or'passage 25 is provided on the inner side" of the-body 13 to freelypassthe set screw 24", and the set screw is adapted t'oengage the upper end of the slot to stop the upward movement of the stem 14: The extension 23' of the stem extends laterally or substantially horizontally from the upper end of the'inain portion 22 to e'xtend' over the upper edge ofthe back 12 and over the interior of the carrier The extension 23may be integral with the main portion 22 of the stem. In accordance with the invention, the extension 23 is of round cross section to'adjustably carry the'arms15, as-will be hereafter described; 1 r

-The arms 15 areprovided to carry the paper engaging needles 16 and are suspended from the extension 23 of the stem. In the particular embodiment of the invention illustrated in the drawing, the needle carrying arms 15 project downwardly from the lower end of ahead 26. The head 26 is an elongated vertical member having a: transverse opening 27 adjacent its upper end for passing the extension 23. The" opening 27 slidably passes the extension 23- so' that the head-and arms 15 may be adjusted toward and away from the back 12 of the carrier and so that the arms may be positioned where their needles 16' effectively engage the paper P. Meansis provided for releasably setting the head 26 against movement along the extension 23. The head 26 is provided with a central longitudinal: opening 28 intersecting the opening 27 and a set screw 3O is screwthreaded into the upper end of the opening. 28

The arms 15 niay be formed of a single length of material or stock having its central portion extending through and fixed in a transvers opening 31 in the head 26. The upper portions "of thear'm's' 15 may. extend or diverge downwardly and outwardly from the head 26, while the lower end portions of the arms are preferably parallel. During normal operation, the lower parallel portions of the'arms 15 are substantially vertical, as illustrated in the drawing. The opening 31 intersects the opening 28 of the head, and the central portion of. the arm assembly eXtending through the opening 31 closes the lower end'ofthe opening 28 to form a chamber for holding a supply of needles for use on the arms 1-5;. It will be apparent that needles may be inserted in or removed-from'the opening 28 by unthreading the setscrew 30: and removing the head- 26=from the extension 23. A needle 16 isJmounted on the lower end of eacharm 15, for engaging, the stack of aperP. The needles 16 are removably attached to the arms; In accordance withthe broader principles of the invention, the needles: may be removablyseoured to the arms-in any suitable manner, In the form of the invention illustrated iirthe drawing, the lower end parts of the arms 15 are in the form of chucks and have Vertical sockets or openings for receiving the shanks of the needles, 'Transverse' slots: 34- extend upward-1y from the lowerends-ot the: arms 15-; Clamping-nuts or chuck nuts 35 are screwthreaded onthe ends or the arms toclamp their split portions onto the shanks of-the needles. The-extreme ends of the. arms 15 and the openings thenuts 35' may be provided witlr co-operatingZ tampered parts to: cause effectivecompression: on thesplit ortions of the arms against the needles 1 6. henuts 85 may be provided with knurled exteriors so that they" may be effectively grasped when it'is desired to' mount or replace a needle 16. a

Any suitable type of sharpened pin or needle may be mounted on thezends of the arms 15f-or' engaging the stack of paper P. The needles 16 operate to piercethe uppermost sheets of paper to hold them against shifting vor displaeemei'it. In the drawing, I hZlVG l'll HSi'lIQ-tP/(l an improved type of paper engaging needle 16;1nounted on the spaced: arms 15. The needles 1-6' are providedwithtapered or pointed lowerends to pierce the uppermost part of the stackofpaper P.- The:

pointed or tapering portions ot th'e' needles 16 a're of triangular cross-sectlon, having three sharpened longitudinal edges 36, The

needles 16 are arranged in the chucks at the lower endsof the arms 15 so that eachhas a:

sharpened. edge 36 facing rearwardly toward.

the back 12 of the carrier C. \Vhen a sheet of paper P is drawn forwardly from the carrier in the direction indicated by the arrow in Fig. 5, the rearwardly facing edge 36 cuts the paper. As the paper is drawn for ward, the angularly related sides of the needle which converge at the edge 36 act to part the paper at each side of the cut so that the paper is not torn.

The means 17 for maintaining the needles 16 in pressural engagement with the paper P is in the nature of a spring means and operates to normally yieldingly urge the assembly of the stem 14, the head 26, and the arms 15 downwardly so that the pointed needles 16 pierce several sheets of paper at all times. The means 17 includes springs 40 arranged at opposite sides of the body 13. The springs 40 are in the form of helical springs and have their upper ends attached to lugs 41 projecting from the stem 14 and their lower ends attached to ears 42 project ing from opposite sides of the body. The lugs 41 project from the shank 14 at the upper end of the portion 22 and at a point above the upper end of the body 10 so that they are adapted to engage the upper end of the body to limit the downward movement of the stem. The springs 40 are under tension and act to feed the needles 16 downwardly into the stack of paper P as 7 paper is removed from it.

It isbelieved that the utility and operation of the device provided by this invention will be readily apparent from the foregoing detailed description. When it is desired to place paper in the carrier C, the stem 14 may be manually raised to disengage the needles 16 from the paper. The head 26 may be adjusted longitudinally along the extension 23 so that the needles 16 will engage the paper at the desired points. 1 Further, the head 26 may be oscillated or tilted on the extension to bring the needles in even engagement with the paper. The springs 40 are sufliciently strong to cause the needles 16 to pierce several of the uppermost sheets of paper P and, upon paper being removed from the stack, the needles are automatically fed downward. The device may be set to handle paper of various sizes and to engage the paper at any desired distance from its inner edge by threading or adjusting the single set screw 30.
