This invention relates 'to improvements in warehouse trucha and particularly to 'iniproveniente in trucks for handling' rolls oi news print paper.

Explanatory to the inventiom l will state,-

here that there an enormous loss cause-d by the now commonly employed methods and means of handling;` news print paper. This loss results from damage done to the edge of the rollso'l. paper durinpY the ,loading or unloading process. This will be better understood when it is known that such rolls et `paper weigh from twelve liiteen hundred pounds and when they are tilted over on the edge igor loading; onto or from a trucli, this enormous weight meshes orbreaks the edge of the roll. Should a roll of paper that is damaged be placed in a printing press, the strip of paper will tear, due to the stress placed thereon, at the damaged placeand as a result the press will have to be stopped and the strip re-threaded .thii'ough' it. Fory this reason, it is customary oraliiress man to inspeet each roll beforeiit is placed in the press and to cut away the roll down to the depth oi any damaged edge portion. This may necessitate the removal of the outery part vof the roll to a depth of from one-iourthinch to one inch and this, in a. short length of time, runs into an enormous amount of waste.

In view of the above,k it has been the principal object of this invention to provide improvements in trucks which permits the loading, or unloading` of rolls ot news print paper therefrom*without placing;` the weight oi the roll on the edge and, in this way, avoids damage to the roll that would require any of the paper to be wasted. n

More specifically staltedthe principal feature of the invention resid esin the details of construction and manner oif Amounting); the nose olf the truck by means et whichy the paper roll is supported. p

Another object of the invention' is to so construct the iframe 'of the truck and to so 4Vlocate the supportingwheels thereon that rolls poi different length may be carried in proper balance that their weight is notsus tained by the operator in handling or moving the truck.

Other objects of the invention reside in the various details oit' construction and combina-` tion oi' parts as will hereinafter be described and in their mode-of operation.

Rei'erring more in detail to the drawings'- 1 and 2 designatespaced apart handle hars a vertical. section *of the truck of the truck fran'ie. i These are provided at-- their upper ends with suitable handhelds 3 and-at their lower ends are cutk on a bevel` as at l? so that when the handle bars entend upward at an angle of approximately sixty ydegrees with the horizontal., theends rest 'flatly againstthe iloor. The bars 1 and 2 are rigidly joined by" a plilrality'o transverse bars 5 and by an axle @lined thereto Abeneath their lower end portions."k This axle is provided atits ends with supporting` wheels 7 #f7 l which would be suiiicient fwidth and diameter' to provide easy movement. e

. Toward the `upper ends, the handle bare havedownwardly extending frames bolted thereto.l These comprise spaced lapart yside kpieces 1O--1O and transverse conncctin5.;`

pieces 11 andlQ. Caster wheels 13 are mounted by standards 14 which 'extend revolubly through apertures in the cross pieces and which aresupported thereon by short cross plates 15 that' are pivotally mounted by pins 16 within slotsl? provided inthe 'stanlilards The 'standards are tired at their lower ends to yolres 18 which mount'thecaster wheels and the head 'of the yoke of each wheel'rests in supporting engagementy with the lower cross piece 12 of 'its frame. The caster 4wheelsordinarily wouldbe used only when longr rolls of ypaper which extend well toward the ends of the handles are' being moved.` v

Then short rolls are handled the casters are detached by turning the cross plates 15 longitudinally of the standards and then withdrawing the standards fromy their frames. The frames may then' beused as supporting legs when the truck is at rest.

The principal feature of'this invention reysides in the details of construction of the nose.

This comprises an upright plate y2O that is Lio curved transversely at. approximately the same curvature as the side surface ot the thus adapting the top of the plate to tilt toward or from the handle bars.

Supported horizontally at the lower edge of the plate 2O is a shoe 28 which has a shortupstanding flange 29 at its rearward edge that is alined with and corresponds to the curvature of the plate 20. llhis shoe is adjustably att-ached to the plate 2O by means of two bolts 30 and 30 which are l'ixed at their lower ends in lugs 31 on the bach side of the flange 29 near the ends of the shoe 28 and at their upper ends are slidably mounted in lugs 32 liXe-fl to the bach side of plate 20. On the upper ends of the bolts are nuts which may be adjusted to different position to limit their downward travel by contact with the lugs 32. This connection provides a rigid mounting` for the shoe but permit-s it to move toward the lower edge of plate 2O for loading and away from it to adord better balance of the roll in transportation. Y

The shoe plate is of substantial width and is provided, in parallel spaced relation, to the rear edge ange 29, with an upwardly pressed shoulder 35 as shown best in Figure 3. This shoulder is formed approximately one and onehalf inches from the flange 29 and onefourth inch above the dat base portion of the plate bet-weten the flange 29 and shoulder. Then the truck is positioned for loading a roll of paper, it is placed as shown in Figure l and in order that the forward edgeof the shoe will be held down against the floor in such position that it may be slipped beneath the roll to be loaded and may not tip back and be gouged into the side of the roll as often happens when loosely hinged, l have fixed rearwardly extending arms 38 to the rear of the flange 29 of the shoe and have attached springs 39 to the ends of these arms and to the-bars l and 2. These springs are of suflicient strength to hold the plate 28 against the floor during loading but do not interfere with movement of the shoe away from the plat-e 2O after the roll of paper is positioned thereon.

ln Figure I have illustrated a nose construction of an alternative type wherein the back plate and shoe 28 are formed in an integral piece. This is provided with mounting ears 22 which are attached to the truck in the same manner as the plate previously described. The shoe piece is likewise provided with theraised shoulder as is the piece 28.

It is also desirable to have a lool-:ing dog Lit) pivotall7 mounted on the axle and adapted to be pressed into holding` Contact with the floor to prevent bac-lr movement of the truck when the roll is being tilted onto it and to assist. in prying-'rolls of paper into place. This dog may be weighted so to automatically lift from the floor when pressure placed thereon.

Assuming the trucl: to be so constructed, it would be used follows:

ldlhen a paper roll is to vbe loaded, the truck is moved up to the roll,V which stands on end, and the handles of the truclrare eirctended upwardly so that the lower ends of the bars l and 2 rest fiatly on the door and the shoe plate 28 is held against the floor by springs V3S). First, the paper roll is tilted i ust enough to permit the shoe to be projected beneath it and the side of the roll to be seated against the lange 29 of the slioeand against the plate 20. lt will be noted, by reference to Figure 3, that when the paper roll is in this position, it is supported on the shoe at-a point approximately one and onehalt inches inside of its edge, and the edge is not in contact with any support by which it could be damaged when the roll is tilted bach onto the truck. The roll is then tilted back against the truck handles and the truck then tilted down, so as to assume the position shown in Figure 2. lt is to be pointed out thatduring this tilting movement of the roll and trucl; the shoe 28 remains on the floor until the bolts 30 have extended to their limit of travel and thus the roll, if it is the longer type of roll, is permitted to come near to a balance over the supporting axle. lf the roll is a shortone, the caster wheels are not desired for the reason that the center of gravity of the roll is forward of the supporting axle and can only be shifted rearwardly thereof by tilting the handles down farther than is permitted when the casters are used. Therefore, the casters should be removed and this can be done quickly by turning the keys l5 with- Yin the slots 17 so that the standards let may be withdrawn; if the roll is a long one, the casters are desired to support the rear part of the truck. as shown in Figure 2. y

By use of a truck having a supporting shoe of this character, the edge of the paper roll which otherwise is damaged, does not comein supporting contact with the base of ,the shoe in loading and this insures that it cannot be mashed or damaged is usually the case when loaded onto or pried about by the ordinary type of blunt nosed trucks. Then no'damage is done to the edge of the roll there is no waste of paper. Such trucks may be made in various sizes, and for various purposes, and its details of construction may be altered without departingfrom the spirit of the invention.
