16 Claims.

'I'his invention relates to a paper cutter stand and has relation more particularly to an apparatus of this kind of a portable type particularly designed for large and heavy rolls of wrapping paper and the like and wherein is embodied means to allow desired lengths of the paper to be unrolled and cut oil.

It is a particular object of the invention to provide a stand of this kind including a vertically disposed paper cutter provided with a cutting bar which will leave a protruding or left overv endon the roll of paper to facilitate the next detachment and wherein such cutter bar is provided along the rear margin of its cutting edge with teeth serving to steady the paper as it is being cut.

The invention also has for an object to provide an apparatus of this kind including a cutter bar mounted in a manner to assure constant pressure on the roll and wherein means are provided to assure the convenient and effective placement of the paper roll in proper position upon thev stand.

The invention has for a further object to provide an apparatus of this kind including a cutter bar having associated therewith a guide bar so constructed and arranged to hold the outer free end of the paper away from the roll and projected outwardly at a proper angle to allow said free end portion of the paper to be conveniently grasped.

A still further object of the invention is to provide an apparatus of this kind including a turntable upon which the paper roll is rested and wherein said turntable is of a diameter materially less than the initial diameter of the roll and wherein is also provided an upper or top pivot arm constructed and mounted in a manner to be readily moved into operative or inoperative position and which arm is readily adjustable in a vertical direction to compensate for rolls of varying heights.

An additional object of the invention is to provide an apparatus of this kind including a turntable upon which the paper roll is to be rested and wherein said turntable is provided.Y

with the yieldable center pin which may be readily depressed so that no obstruction will be offered 'while placing a roll of paper upon the turntable.

It is a further object of the invention to provide an apparatus of this kind including a base having ground engaging wheels one ofwhich is of a -castor type and said castor wheel having operatively engaged therewith a handle member (Cl. 24E-55.5)

which, when in one position, serves to maintain a brake element in holding engagement with the castor wheel and wherein additional means are provided to hold the castor wheel against swivelling when the brake is effective. 5

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved paper cutter stand whereby certain important advantages are attained and the device rendered sim- 10 pler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

'I'he novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, `I will now proceed to describe the same with reference to the accompanying draw- I ings, wherein:

Figure 1 is a vertical sectional view with portions broken away and parts in elevation of a paper cutter stand constructed in accordance with an embodiment of my invention;

Figure 2 is a horizontal sectional view taken through the upper portion of Figure 1, certain i'f the parts being generally indicated by broken mes;

Figure 2a is a fragmentary view in perspective of the cutter member as herein comprised:

Figure 3 is a view in perspective of the. stand as herein disclosed;

Figure 4 is a view in bottom plan of the base;

Figure 5 is a fragmentary transverse sectional view taken through the forward portion of the apparatus and illustrating certainfeatures of the braking mechanism; A y

Figure 6 is an enlarged fragmentary sectional view partly in section and partly in elevation illustrating in detail the mounting for the post and the means for rotating the sleeve on the post and for holding said sleeve` at the limit of its movement in opposite` directions.

As disclosed in the accompanying drawings, B denotes a base member of desired dimensions and configuration and which has depending therefrom suitably Y positioned strengthening flanges 2 and a depending ange 3 dening the marginal portion of the base member. Also depending from the rear portion of the base member B substantially parallel to and in close proximity to the flange 3 are the additional anges 4 and said flanges 4 and the flanges 3 are provided with the transversely aligned depending lugs 5 which, Whendesired, may be employed as rests for contact with a suitable supporting surface.

The flanges 2 and 4. however, coact to provide pockets to receive the ground engaging wheels 6 of desired diameter and which are held in desired position by the headed axles 'I freely insertible through the iianges 2 and 4 and the hubs cf the wheels 6. As herein disclosed, these axles 'I are of a length to extend inwardly beyond the flanges 4 so that the cotter pins 8 or the like may belinserted through said extended portions to maintain the desired assembly. It is believed to be obvious that the simplicity of mounting for the wheels 6 readily permits the same to be applied or removed when desired.

'lhe opposite or front end portion of the base B at its transverse center has depending from the iiange 3 a lug 9 also extended to provide a leg or rest for the base when the supporting wheels are not used.

The forward portion of the base B at its transverse center is provided therethrough with Van opening Ii) through which is inserted from beflow the stem II of the fork I2 for the castor wheel I4. The base or intermediate portion of the fork i2 is formed to provide a shoulder I5 surrounding the stem II and contacting from below the base B. The stem II projects a desired distance above the base B and threading upon the stem II for contact with the base B from above is a locking or holding nut I6 whereby the fork I2 is maintained in swivelled engagement with the base B.

The lower portion of the stem Il has disposed radially therethrough a relatively large opening il in which extends the upper portion of a tubular stem I8 connected to the central portion of a brake shoe I9 for coaction with the wheel I4.` The end portion of the stem I8 within the opening I'I is dened by an outstanding ange 20 and Ainterposed between this iiange 20 and the bottom Wall of the opening I'I is an expansible member 2| herein disclosed as a coil spring encircling the stem I8. This member or spring 2I serves to urge the shoe I9 into release position.

Slidably and snugly engaging from above within the stem I8 is an elongated member or piston 22and interposed between the inserted end of the memberfor piston 22 and the inner or closed end of the stem I8 is a coiled brake spring 23 of desired tension. The outer end portion of the member or piston 22 is enlarged to provide a head 24, the outer face of which is ilat and in a plane substantially at right angles to the axis of the stem i8.

The top portion of the stem II of the castor fork is bifurcated,` the' kerf 25 of which is in communication with the opening II. This kerf, however, is preferably of a width less than the width of the opening I'I. Extending withinthe kerf 254 is the lower or inner end portion of a handle member H, said portion of the handle member H within the kerf being pivotally held to the stem II by the pin 26 carried by the stem Il and intersecting the kerf 25.

The end of the handle member H inwardly of or below the pivot pin 26 is formed to provide two angularly related faces a and b, the face b being disposed inwardly and forwardly of the handle member H and on such angle with respect to the rear face a to allow the member or spring 2I to move the shoe I9 into released position when the handle member H is swung forwardly into a position to pull the base B.

,The meeting ends or junction of the faces a and b provide a high point or cam c which, as the handle member H is drawn back into inoperative position, contactswith the member or piston 22 and forces the shoe I9 through the interposed spring 23 into braking engagement with the wheel I4 thus holding the base B against movement.

The handle member H need not be raised to its full extent to apply the brake shoe I 9 as the position of the high point or cam c is such that when the handle member H has been raised to an angle of about 60 the depression of the member or piston 22 will start and will gradually increase its power until the handle member H is thrust back to full 90 whereupon the shoe I9 will be locked down in a steadfast position.

It is to be pointed out that the handle member H is effectively held in its fully raised position under the action of the expansive pressures of the springs 2I and 23 which will firmly press the member or brake piston 22 against the face a of the handle member and in this manner firmly locking the handle member with snap action in fully raised position. It will, therefore, be noted that the brake locking and handle holding operations are simultaneous. It is of importance to provide means to prevent the full raising of the handle member H and the setting of the brake shoe I9 until after the handle member H and, of course, the castor wheel I4 have been aligned and centered to the front. For this purpose the base B has extending upwardly therefrom a flange 21 positioned rearwardly of the opening I0 but in `relatively close proximity thereto and substantially concentric with the rear half of the opening I0 or of the stem II. The central portion of this ange 21 is formed to provide an elongated centering slot or channel 28 which is in direct longitudinal alignment with the axial center vof the opening I0. The handle member H at its pivoted end portion is provided with a rearwardly directed lug or tail piece 29 of a length to readily enter from above within the slot or channel 28 upon raising of the handle member H after such handle member has been properly centered. However, when the handle member H is not properly centered, upon lifting movement being imparted to the handle H the lug or tail piece 29 will contact from above to prevent the handle member H being fully raised or being raised to an extent to make .the braking mechanism effective.

The lug or tail piece 29 when within the slot or channel 28 also provides an effective means for holding the castor wheel I4 against swivelled movement which is of particular importance and advantage while a roll is being applied to the base or the paper unrolled and cut.

Positioned within the slot or channel 28 and anchored to the bottom wall thereofas at 30, is an upstanding spring clip 3| which frictionally engages the lug or tail piece 29 when the handle member H is in its fully raised position. This clipr 3l is provided as an auxiliary means for holding the handle member H in its fully raised position should the holding means -hereinbefore referred to under the action of the springs 2| and 23 for any reason become inoperative.

The rear portion of the base B has disposed therethrough at its transverse center or in longitudinal alignment with the opening I0 a second opening 32 surrounded by the pit or depression 33 provided in the top face of the base B. This pit or depression 33 is surrounded'by an upstanding annular flange 34 which may also be referred to as a turntable guard. Positioned within the pit or depression 33 is a turntable T which is of adiameter materially less than the initial diameter of the paper roll R placed thereon. This turntable T at its axial center is provided with a depending tubular trunnion 35. 'Ihreading upon the lower portion of this trunnion 35 is a bearing cone 36 coacting with a ball bearing assembly 31 which also engages within an annular raceway 38 provided by enlarging the lower portion of the opening 32.

This bearing cone 36 is readily adjustable as desired and is maintained in its desired adjustment thru the medium of the lock nut 39 threading upon the trunnion 35.

The peripheral portion of the turntable T at its under surface is formed to provide an annular raceway 40 which overlies an annular raceway 4I provided in the outer marginal portion of the pit or depression 33. Associated with these raceways 40 and 4I is a ball bearing assembly 42. At this time it is to be stated that the ball bearing assemblies 31 and 42 are each of a typ-e hav-` ing a suitable retainer associated therewith so that the balls will be properly spaced and may be readily installed or easily removed.

It is to be noted that the flange or guard 34 closely approaches the peripheral edge or face of the turntable T but that the top of the turntable T is positioned slightly above said ange or guard. This flange or guard while serving to enclose the upper bearing assembly also operates to relieve to some extent pressure which may be exerted on the rim portion of the turntable.

The bore 43 of the trunnion' 35 is extended up through the axial center of the table T and snugly and slidably tting within this bore or opening 43 is a. bottom pivot pin 44, the upper portion 45 of which is tapered. 'I'he lower portion of this pin 44 has a bore 46 open at the bottom of the pivot and extending within said bore 46 is a depressible pivot spring 41 of desired tension. 'Ihe upper or inserted end portion of this spring 41 is held to thepin 44 `by a cross pin 48 while the lower or outer end portion of the spring 41 bears against and is engaged with a cross pin 49 carried by and intersecting the lower portion ofthe trunnion 35. The spring 41 serves to normally maintain the pin 44 projected up above the top or working surface of the table T yet readily permits the same to be depressed by the weight of the paper roll when being applied to the table. When 'the roll has been properly centered the spring 41 will cause the bottom pin 44 to readily project up into the conventional wood center block 56 of the roll R. The tapered portion 45 of the pin 44 is providedto allow the pin 44 to' properly set into wood center blocks that may have a large or non-standard size of hole. Furthermore, this tapered portion 45 as a resultof the upward pressure on the pin 44 will also properly engage within the hole of the wood center block should it be for any reason up out of its proper position in the core.

At a point between but in alignment with the openings I and 32 the base B is provided with a third opening I. This opening 5I is preferably positioned closely adjacent to the opening I0 in order to allow center clearance for the paper roll R initially mounted on the turntable. Extending from above through this opening 5I is the lower end portion of an elongated and vertically disposed tubular post 52. This post 52 extends a slight distance below the base B to per surface of the ybase B 4whereby the post 52 is eiectively held against rotation and at the same time providing further means for Vmain-l taining the post in proper assembly. The upper end of the post 52-is open and snugly insertlble within the post 52 through said. upper open end is an elongated member or bar 51. This bar 51 together with the bore of the post 52 are cylindrical in cross section so that upon raising the member or bar 51 a predetermined distance the bar or member 51 will be free to rotate. However, the upper portion of the member or bar 51 is provided with an outstanding and longitudinally directed key 58 which engages within a keyway 59 provided in the upper portion of the post 52 and' open at its upper end. This key 58 is normally engaged within the keyway 59 so that the member or bar 51 is eifectively held against turning movement. This normal engagement o f the key 58 within the keyway 59 is maintained by a compression spring 60 of suitable tension. This spring 60 surrounds an elongated shank- 6I secured to the inserted or lower end of the member or bar 51 and terminating in an enlargement or head 62. The spring 60 is interposed between this enlargement 62 and a cross pin 63 carried by the post 52.

The member or bar 51 has its upper end portion at all times above the upper end of the post 52 and carried by said upper portion of the member or bar 51 is a laterally disposed arm 64, the outer end portion of which carries a depending top pivot 65 to engage within a conventional wood center block 66 of the paper roll R. This top pivot, as herein disclosed, comprises a revolvable tapered sleeve 61 having associated therewith in a conventional manner the ball bearing 68. The outer end portion of the arm 64 above the top pivot 65 is provided with a head or enlargement 69 to provide means whereby the -arm 64 may, when desired, be raised and swung into or out of working position. It is believed to be obvious that when a roll R is to be re-apv plied the arm 64 is swung laterally to one side out of the way. Y 1

It is also to be stated that when the arm 64 is in operative position it is held in constant and true alignment with the lower pin'44. It is also thought to be evident that the up and down movement of the member or bar 51 within the post 52 will allow the effective mounting of paper rolls of varying heights or when the upper wooden center block 66 may be pressed in\ too far or be otherwise out of position. l

Snugly surrounding the post 52 but free to rotate is a sleeve 10 and keyed, as at 1|, to the lower end portion of this sleeve 10 is a surrounding casting 12 pi `)vided with an outstanding lug 13 which overlies and extends across an arcuate slot 14 of desired length produced through the base B and at a side lateral of the post 52. Extending up through this slot 14 is an upstanding pin 15 carried by an elongated rod or bar 16 underlying the base B and having slidable engagement through a suitably positioned depending flange 2. Interposed between this flange and a head or enlargement 11 xed to the bar or rod.16 is a coil spring -18 off desired tension and for a purpose to be hereinafter referred to.

The sleeve 10 is held in position upon the post 52 by a, holding band or collar 19 surrounding the upper portion of the post 52 and held thereto by a binding screw 80 or the like. The sleeve 10 at desired points therealong has rigidly secured thereto by welding or otherwise the end portions of the cutter bar arms 8| of desired length and each possessing a certain degree of inherent resiliency. The outer end portions of these arms 8| are rigidly attached to the vertically disposed paper cutter member M. This cutter member M has its lower end terminatingabove but in close proximity to the top surface of the turntable T so that its eiiciency will in no way be impaired as a result of contact with said turntable as the diameter of the paper roll R diminishes. These arms 8| are preferably curved and formed of light weight steel strips, the resiliency or flexibility of which assure the cutter member having uniform contact with the roll. 'I'his contact of the member M with the roll is definitely assured, however, by the pressure of the spring 18 hereinbefore referred to. However, when these arms 8| are swung outwardly to bring the lug 13 past center, this spring 18 will operate to hold the arms 8| in such position.

The cutter member M, as herein disclosed, comprises a fiat main plate 82 of desired dimensions and which has its outer or forward longitudinal margin defined by an outwardly and inwardly inclined cutting blade 83 co-extensive in length with the plate 82. The inner or rear longitudinal margin of the plate 82 is defined by a back plate 84, the free longitudinal marginal portion 85 of which is disposed on a predetermined curvature to facilitate the drawing of the paper from the roll. It is this portion 85 which has direct contact with the roll proper. The upper end of the member M is provided with an end plate 86 to which is welded or otherwise secured the upper end portion of a guide bar 81. This bar 81 is in relatively close proximity to the curved portion 85 of the plate 84 but separated therefom a distance sumcient to provide a slot 88 through which the paper sheet passes. This guide bar 81 does not extend the entire length of the member M but only for a distance not more than one-half the length of the cutter member and preferably only about one-third of such length. By having the guide bar 81 of this character it has been fully demonstrated in practice that by its relatively short length this guide bar is just as efficient in projecting the paper away from the roll as if it were of full length. c

, T'he arms 8| are of such length whereby the -contact of the rounded portion 85 of the plate 84 determines the desired `point the paper leaves the roll, and the pressure of the portion 85 upon the roll and particularlyas a result of the action of the spring 18, assures a tight winding of the paper roll as the paper cannot be forced up or back by the paper that has been unrolled. In other words, the contact of the member Mwith the roll operates to prevent back unravelling of the paper remaining on the roll. It is also to be noted that the plate 82 and knife 8 3 together with the plate 84 are so constructed and arranged to assure a 'projecting free end portion. of the paper after a cutting operation so that the paper can be again conveniently grasped to pull off another length.

. The free or leading edge of thea blade 83 is the cutting edge along which the paper is torn or cut. With the cutting edge left smooth or. plane,

thus assuring a corresponding straight and smooth edge at the cut.

The apparatus as a unit is given mobility by the use of the removable castor wheels 6 and |4 but if desired these castor wheels may be dispensed with and the base allowed to be supported by the lugsv and 8 hereinbefore referred to.

When the handle member H is in its fully raised position but preferably has its upper portion closely approaching the post 52 or more particularly the sleeve so that when the stand is at desired location for use, the handle member H will not extend outwardly to a position that might result in injury or interfere with the effective use of the stand. A

The turntable T is of a diameter about threefifths of the longitudinal diameter of the roll R mounted thereon. This diameter of the turntable T is adequate to bear the roll R in even balance and by having the turntable T relatively small is made possible positioning the upper bearing assembly 42 very close to the peripheral margin of the table T. This placement of the assembly 42 eliminates any overhanging portion that could be bent or otherwise dis-aligned and by having the turntable T small in size it is easier to mount; is lighter in weight; revolves more easily; and is less conspicuous. y

The pit or depression 33 results in the turntable being deeply embedded in the baseB so that the center of gravity is kept at a low point and thereby facilitating placing of the roll R on the table T as well as resulting in the base being neat and compact. The upper assembly 42 is of a thrust type and the race-ways 40 and 4| are deep so that the balls of the assembly engaged within said raceways act as keys to keep the table in alignment especially at times of unusual side pressure, as for example when a roll R is being applied upon the table. The lower bearing assembly 31 is of a combination radial and thrust type operating in the raceway 38 and associated bearing cone 38.

From the foregoing description it is thought to be obvious that a paper cutter stand constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.
