' snnnrnrnn HOLDER.

Application led April 1, 1926. Serial No. 99,153.

For convenience in transporting or shipping and storing sand paper it'has been a common practice heretofore to put the same in bales of several reams to the bundle, and recentlyit has been the practice to put the sand paper in boxes made of pasteboard or cardboard and much trouble and inconvenience has been caused by 'breakage due toV piling the boxes one upon another, for storage or transportation.

Certain objects of my invention are to overcome the objections incident to the use of boxes made of pasteboard or other flexible and brea-kable material as heretofore for packaging sand paper, and to provide a box of the character referred to which will withstand the pressure of'any number of boxes piled one upon another, together with simple and ellicient means whereby sand paper may be handled in the original packages conveniently arranged in any desired number and held in separated relation in such manner as to permit easy access toV their contents and without danger of vcrushing or breaking a box byV pressure of other boxes thereon due Vto packing and storing ortransporting sand paper in pasteboard boxes piled one upon another in large numbers.

Another object is to provide means whereby the individual boxes may be conveniently handled, whether singly or stacked one upon another, when it is desired to remove a sheet or sheets of sand paper therefrom as needed from time to time, or for the purpose of transporting the boxes from place to place for refilling the same.

The invention will first be hereinafter more particularly described, with reference to the accompanying drawings, which are to be taken as a part of this specificatiomand then pointed out in the claims at the end of the description. y f

In saiddrawings, Fig. lis a perspective view of a pasteboard box in course of construct-ion, designed and adapted for use in packaging sand paper for transportation or storage, in accordance with my invention;

Fig. 2 is a detail sectional view taken on the line wof Fig. 5;

Fig. 3 is a perspective view of a metallic frame' structure designed and adapted to ernbrace and reinforce a pasteboard box of the character referred to to adapt it to withstand the pressure of e number of boxes piled l box together.

thereon, without danger of being crushed or broken;

Fig. 4 is a perspective view of a stack ofboxes of the characterv referred to with reinforcing means thereon; the lowermost box inthe `stack being partly withdrawn from its reinforcing means and having a hinged end-portion thereof lowered for convenience in removing a sheet or sheets of sand paper therefrom; and i Y y Fig. 5 is a longitudinal vertical sectional view through one of the boxes Aand its reinforcing means.

VReferring to said drawings, inwhich the same reference letters are used to denote corresponding partsin different views, I have shown in Fig. l a piece of pasteboardj cut and shaped to form a box having an open top and upturned portions ne? and a2,- to

form the sides and ends, respectively, of the completed box; said endportions a2 being turned'inwardly and secured together and reinforced by overlapping integral exten- Vsions a3 ofthe bottom of the box at each end;

said extensions being upturned and' bent over said endportion a2 and then downwardly and having the free enda4 thereof on the inner side of the box bent substantially at right angles to said downwardly bent portionand secured to the bottom of the box by means of a button-like flap a5 cut out of said bottom and arranged to abut against and overlap said free end-portion at, thus securing the end-portions of the As will be seen the main side portions or sections a Aof the box'are longer than the side portions or sections al, and

vthe upper parts of the latter Sections are ycut away' so that theyincrease in depthy toward the front end-portions a2. vThe bottom of the box is slit or grooved transversely at yan intermediate point to form a hingelike connection so that the front end-portion or extension a6 thereof may drop down-` into the position shown in Fig. 4L for removing sand paper therefrom. The box constructed as described is inserted in one end ofa container B, also made of pasteboard or the like and havinga closed bottom, top, sides and end, but open at one end so that the box with the open top may be inserted therein, and thereupon the assembled 'parts are inserted withinan open frame-work such as shown in Fig. 3

'of the drawings, consisting* preferably of thin pieces of sheet metal C of angular form in cross-section secured by spot welding or other means, as at o, in the four inner corners ofend pieces C1 of oblong rectangular form having horizontal top and bottom portions or bars connected at each endrby upright portions o1, either integral therewith or rigidly secured there. to, as shown, thus forming a crate-like structure within which the pasteboard box may be inserted to provide a reinforcement therefor while permitting the box to slide back andrforth so that it may be readily withdrawn and replaced at will. It will be observed that the end pieces or members C1 of the crate-like structure are in the form of continuous bands extending around the angle bars or connecting members C at opposite ends thereof and are secured thereto on the outer sides thereof so t-hat an unobstructed slideway'is provided by said conn necting members to permit the container to nt snugly within the crate-like structure and adapt it to be easily inserted at either end and withdrawn therefrom without coming into contact with thev end pieces C1. As will be seen, any number of pasteboard boxes of the described construction containingY sand paper and reinforced by metallic frame structures of the described form may be` piled one upon another, as shown 1n Fig. t of the drawinos, without danger of break-l ing or crushing Va box or boxes underneath the pile orV stack during transportation or while. in storage for use in removingsheets of sand paper therefrom very much in the same manner that books are removed from an ordinary sectional book-case, by simply partially withdrawing a box from its reinforcingmeans so that the hinged end portion thereof may drop down into the position shown inFig. l of the drawings for convenience in removing a sheet or sheets of sand paper from the box or re-tilling the same.

For the purpose of withdrawing the pasteboard box having the open top from the eontainer' in which it is enclosed, a pieceV of fabric or other flexible material is glued 'or Y otherwise secured underneath the bottom of the front hinged end-portion of the box to provide a flap or handle D, which may be readily grasped between the thumb and foretinger for pulling the box out of the con-i tainer. f Y

l/Vhile I have shown and described as one element of my improved sand paper holder a pasteboard box constructed in a single piece and adapted to serve as the sand paper holder proper, it will be understood of course that other constructions may be used, as the thing desired is a box similar to the described construction having an open top and a hinged front, and adapted for insertion in an enclosing case or container open at one end only; the latter boing adapted to be inserted in the crate-like reinforcing means having longitudinal and transverse frame members spanning the container along both ends thereof and along its edges tn both its upper and its lower sides, so as to prevent the container from being crushed or injured under pressure'of superposed boxes in a stack. l also desire it to be understood that the word pasteboard7 as used in the appended claims is intended to include other similar light and flexible material such as cardboard, for example, from which boxes of the characterreferred to may be easily constructed at very little expense, and which by reason of the character of the material usedin their construction require reinforcement t-o prevent injury thereto when the boxes are piled one upon another with consequent danger of crushing the material of which they are made.

.ln some cases it may be desirable to-use a sand paper holder or box made of pasteboard or other similar flexible and brealable material, without the hinged front end portion, for insertion in acont'ainer of the described construction or for insertion in the crate-like reinforcing structure without the container or inner box; my invention in its broader aspects being designed to include such arrangements.

Having thus described my invention, what l Vclaim as new and desire to secure by Let#V ters Patent of the United States is:

.1. A reinforced sandpaper holder comprising inner and outer boxes made of pa'steboard or lthe like, one slidably inserted within the other; the inner box having an open top and a hinged end-'portion adapted to d rop down when withdrawn from the outer box; the duplex box being slidably inserted in acrate-like reinforcing structure comprising frame members which extend across and around the ends of the duplex box and other members 'which extend along the upper and lower longitudinal edges of the duplex box, whereby the assembled boxes are kept intact when piled one upon another while permitting the inner pasteboard box to be partly withdrawn from the outer box for removing sheets of sand paperv therefrom or for refilling the same without disturbing the pile; said outer box being adapted to be readily withdrawn from said reinforcing structure together with the inner box and the inner' box being adapted to be withdrawn from the o uter box without-with drawing the latter from said reinforcing structure. y

2. A reinforced sand paper holder comprising inner and outer boxes of shallow form made of vpasteboard or other flexible and breakable material, the inner box having an open top and a front hinged end-,portion adapted to drop down when partly Cil withdrawn from the outer box; the latter being open at one end only, and a metallic crate-like reinforcing vstructure which the duplex box is inserted; said structure having .longitudinal and transverse frame members `spanning the outer pasteboard box along its ends and along its edges on the upper and lower sides thereof, so as to prevent the pasteboard box from being crushed or injured 4under pressure of superposed boxes in a stack; said longitudinal frame members heilig of angular form and secured within the four corners of said transverse frame members; the latter being in the form of continuous bands extending aroundv and secured to the outer sides of said longitudinal members so as to provide an unobstructed slideway for the insertion and removal of said holder.

3, A reinforced sand paper holder com-V prising a box of shallow form with open top and hinged front end-portion inserted in a box of similar form open at one end only; said boxes being made of pasteboard or other flexible and breakable material and inserted in a metallic crate-like reinforcing kstructure having longitudinal and transverse frame members spanning the pasteboard box along both of its ends and along both of its longitudinal edges on both the upper and lower sides thereof, so as to pre` vent the pasteboard box from being crushed or injured under pressure lof superposed boxes in a stack; said longitudinal frame members being of angular form and secured within the four corners of said transverse frame members; ,the latter being inthe form of continuous bands extending around and secured to the outer sides of said lon-l gitudinalr members so as to provide an unobstructed slideway for the insertion and removal of said holder at either end thereof.

4. A reinforced sand paper holder comprising two telescopically connected boxes made of pasteboard or the like; the outer box being open at one end only, and the inner box having an open top and a hinged within c end-,portion adapted to drop down when withdrawn from the outer box, and a reinforcing crate-like structure embracing the duplex box, the latter being slidably inserted in said structure at one end thereof; said crate-like structure consisting of strips p withdrawn from the outer box for removing sheets of sand paper therefrom or for relling the same without disturbing the pile.

5. A reinforced sand paper holder comprising two telescopically' connected boxes made of pasteboard orv the like; the outer box being open at one end only, and the inner box having an open top and ahinged end-portion adapted to drop 'down when withdrawn from the outer box, and a reinforcing crate-like structure embracing theV duplex box, the latter being slidably inserted in said structure at `one end thereof;

said crate-like structure consisting of stri-ps of metal which extend transversely across and around the ends of the duplex box, and other strips which extend along the upper and the lower longitudinal edges of said box, said transverse strips being secured to the ends of said longitudinal strips; whereby the assembled boxes are kept intact when piled one upon another in large numbers while permitting the inner box to be partly withdrawn from the outer box for removing sheets of sand paper therefrom or forrefilling the same without disturbing the pile; said crate-like structure being adapted to permit the duplex box to be inserted therein at either end thereof.
