VERTICALLY DISPOSED MENSURATION DEVICE FOR PULLING PAPER FROM ROLLS Filed Jan. 215, 1965 3 Sheets-Sheet 3 United States Patent This invention relates to a device for unreeling paper from a roll, measuring the unreeled portion thereof and 3,136,192 Patented June 9, 1964 a top beam 16 and a bottom beam 17, both of a generally U-shape cross section, and including a pair of suitably angularly disposed support braces 18, disposed at each end and conventionally secured to the top beam 16 and to the floor.

A rectangular block 19, preferably of iron metal, is

4 disposed at each end of the mechanism and conventionalthereafter cutting away the measured portion and more particularly this invention relates to such a device disposed vertically to save valuable floor space.

There are many mensuration devices for pulling out paper from a roll and thereafter measuring and cutting the portion pulled out. All, or substantially all these devices are horizontally disposed so that the machine requires a vast amount of area for its operation. This is particularly so where the paper roll is five feet or more in width.

It is an object of this invention to provide a mensuration device for paper which is vertically disposed and hence requires a minimum of floor space.

It is another object to provide a paper dispensing device which is adapted to dispense simultaneously one or more sheets of unreeled paper.

It is a further object to provide a vertically disposed paper dispensing machine which is loaded with paper at either end and is optionally operable from left to right or from right to left.

These and other objects of this invention will become apparent upon reading the following descriptive disclosure taken in conjunction with the accompanying drawing of an illustrative embodiment thereof and in which:

FIG. 1 is a side view of the invention showing paper dispensing rolls on each end and showing the sheet hold er in its initial position and showing in outline the sheet holder in its pulled out or leftwardmost position,

FIG. 2 is a section view taken substantially on line 2-2 of FIG. 1 and the paper holder in its initial position, and

1y secured to the floor. The bottom beam 17 is bolted to the interior surface of each block 19 by bolts 20.

Each block 19 is provided with a pair of suitably spaced-apart wells comprising an inner small diameter cavity 21 communicating with a larger diameter recess 22 which latter communicates with a recess 23 of largest diameter forming a ledge 24 upon which a conventional annular thrust bearing 25 is disposed.

The roll of paper 27, generally about five feet or more wide, is provided with a suitable core 28 to the lower end of which is secured a cone shaped bearing surface 29 adapted to engage the co-acting ring of the thrust bearing 25. A suitable coil spring 30 is disposed in cavity 21 and engages the bottom of core 28 to in-part and suitably support said core and paper roll 27.

A pair of suitably spaced-apart guide rollers 31 is disposed in between and at each end of the top and bottom beams and conventionally secured thereto through the 7 use of conventional bearings 32 and support plates 33.

A slotted stationary cutter plate 34 (FIG. 6) is provided with flanges 35 at each end and bolted or riveted to both the top beam 16 and the bottom beam 17. A slotted cutter plate 36 is secured hingedly to the stationary cutter plate 34 by means of a pair of suitable hinges 37 suitably spaced-apart to permit the paper 27 to pass between the hinges.

A pair of suitable U-shaped rod clamps 38 are disposed through suitably located apertures in plate 34. A

' wedge 39 is suitably secured to each moveable plate 36 in its leftwardmost position in outline, and showing a pair of guide rollers on each end as well as a slit plate of each end,

FIG. 3 is an end view of the device and the manner of bracing it,

FIG. 4 is a section view taken on line 44 of FIG. 1 and showing the paper holder,

FIG. 5 is a section view taken on line 5-5 of FIG. 1 and showing a hinged paper slitter and the manner of holding the top edge of a slit paper against falling,

FIG. 6 is a perspective view of the slitter, brokenaway in part,

FIG. 7 is a side view of the hand operated cam lock means used to lock the paper holder to the frame after it has been pulled away from the paper roll the desired measured length,

FIG. 8 is a side view of the lock means in locked position showing the paper holder lifted off the channel floor and locked to the bottom frame,

FIG. 9 is a view taken on line 99 of FIG. 6 showing the means of holding the cut paper from falling after it is cut,

FIG. 10 is a view taken on line 10-10 of FIG. 1 showing the manner of locking a respective leading edge of a paper sheet to its respective side of the paper holder so that it may be then pulled in the respectively desired direction, and

FIG. 11 is a view taken on line 1111 of FIG. 1 showing a leaf spring biasing each of two hinged paper grasps, said grasps being disposed on the paper holder.

Turning to the drawing, a metal frame 15 comprises in the corner thereof so that a leg of a clamp 38 frictionally engages the wedge surface forcing the moveable plate against the paper 27 disposed between

plates

34 and 36 thereby clamping it in a vertical position.

The slot 40 of hinged plate 36 over lies slot 41 of the stationary plate (FIG. 9) so that the paper therein may be cut vertically. To prevent the cut paper from falling a holder clamp is preferably provided.

This clamp (FIG. 9) comprises a rotatable handle 42 suitably secured to a'suitable post conventionally secured to the moveable plate 36. The hinged plate 36 is provided with a suitable aperture 43 and a suitable leaf spring 44 having a wedge shaped cam surface 45 is secured by a 'rivet 46 over the aperture 43. The base of the wedge 1 45 is preferably provided with a felt pad 47 to bear upon the paper 27 so not to disfigure it.

The spring 44 normally retains the felt pad 47 away from contact with the paper 27. After a sheet of paper has been pulled out and is ready to be cut, it is clamped by the action of handle 42 riding the inclined wedge or cam 45 thereby forcing the felt pad 47 lockingly against the stationary plate 34. Thus a paper 27 cut by a knife 4: is retained in its upright position by said felt pad 4 As shown in FIGS. 1 and 2, this invention accommodates 4 rolls of paper. Thus two sheets of paper may be pulled simultaneously from each end. The paper, used in printing is expensive, and may be of diiferent thickness. With slight changes an extra pair of rollers can be added to each side so that four sheets of paper may be pulled out to the desired length and then cut at one time.

In order to pull the paper out to the desired length a moveable lock plate 50 is provided. Lock plate 50 (FIG. 10) is provided with three pairs of clamping means for clamping paper fed from either side of the device.

i which an indicator 55 is attached at the top as by rivets.

Also in this central area are located the posts 56 for the pivot arms 57 (FIG. and the posts 58 for the leaf springs 59.

Three clamp elements comprising a central plate 6t) to which a pair of seizure plates 61 are hingedly secured are spot welded at the central plate 60 tothe underlying lock plate 50. Wedged shaped cams 62 are welded to each seizure plate 61so that handle 57 rides up the cam inclined plane to seize the paper 27 between

plates

50 and 61.

The seizure plates 61 arebiased gently against the plate 50 by means of leaf spring 59, thereby permitting the paper 27 to be pushed in between

plates

50 and 61 in the absence of cam pressure on cam 62.

A scale 63 is provided and is calibrated from both ends, due allowance being had for the distance between slot 40 and the initial reading on the scale as well as for the distance between the vertical edge of the paper and the center of plate 60.

For printing trade purposes lengths of paper less than about two'feet are never used in the Wide sheets. Thus, for example, the initial reading on the scale may be calibrated to be two feet. p

As can be seen from FIG. 1, the paper may be clamped to either side of the handle 54 on the lock plate 50 and,

the plate then pulled respectively to the right or the left. After it is pulled the desired length as measured on the scale 63, the lock plate 50 is locked in place by means of a conventional hand operated cam lock 64 (FIGS. 7 and 8). The cam lock 64 is disposed on the back side of plate 50 at its bottom.

As shown in FIG. 8 the bottom beam 17 is provided with a. pair of inwardly disposed horizontal ledges 65. The action of cam 66 by operation of the cam handle 67 raises the wheels off the bottom wall of the bottom beam 17 so that they seize a ledge 65. When the lock cam 64 is not in use the handle 67 is seized in a conventional clip 68.
