1 Claim.

This invention relates to an improved form of stationery guiding instrumentalities designed primarily for use in guiding unperforated multicopy stationery during the process of feeding it from a supply roll.

When unperforated multicopy stationery is fed from a supply rollby friction feeding instrumentalities into and through a printing machine, such as a teletypewriter, there is a tendency for the individual sheets of the multicopy stationery to weave sidewise and to become lat- I they tend to cause bulging and buckling of the individual sheets of the multicopy stationery. This bulging and buckling impede, and sometimes prevent, the proper feeding of the stationery. This often results in tearing the edges 5, of the stationery and in improper positioning of the words typed upon the stationery.

The purpose of the present invention is to reduce the sidewise weaving and lateral misalignment of unperforated multicopy stationery during feeding operations. In accordance with this invention, a supply roll of unperforated multicopy stationery is placed upon a spindle having a circular/ end-plate adjustably and detachably mounted on each end of the spindle and held closely against the edges of the supply roll. D

to the fact that this end-plate has a larger ameter than the supply roll has, the individual sheets of stationery cannot weave sidewise nor become laterally misaligned while they are on the supply roll but are held tightly in correct latoral alignment.

Although it has been stated above that these stationery guiding instrumentalities are designed primarily for use in guiding unperforated multi- 45 copy stationery, they may also be used in connection with the feeding of perforated stationery whether of the multicopy type or not, as well as single sheet unperforated stationery. These guiding instrumentalities are of great assistance 50 when used for guiding multicopy stationery because the misalignment of the individual sheets of this type of stationery is much more objec tionable than the misalignment of single sheet stationery. However, they are most useful when 66 g eyare used for guiding unperforated multicopy stationery because such stationery is fed only by friction feeding instrumentalities which are not as capable of reducing misalignment of the individual sheets of stationery as are the sprocket feeding instrumentalities used for feeding per- 5 forated stationery.

The invention will now be described in detail in connection with the drawing in which:

Fig. 1 shows "the spindle used for supporting a supply roll of stationery; l0

2 illustrates the appearance of one of the end-plates when it is not mounted on the spindle; and

Fig. 3 represents the stationery guiding instrumentalities completely assembled for guidl6 ing stationery from a supply roll.

It can be seen in Fig. 1 that the spindle I has a projection 2 at each end. The purpose of these projections 2-2 is to enable the spindle to be rotatably mounted in a printing machine, such as 20 a teletypewriter. It can also be seen that the spindle I has two

circumferential grooves

3 and 4 in and near its left end and two more circumferential grooves 5 and 6 in and near the right end. grooves in and near each end of the spindle is to enable it to be used with supply rolls of diflerent widths as will be explained later. For purposes of illustration, it may be assumed that it is intended to use the spindle I for supporting sup- 30 ply rolls which are either eight or eight and onehalf inches wide. On the basis of this assumption, the supply roll ll, shown in Fig. 3, would be eight and one-half inches wide, the distance between the grooves 4 and 5 would be about eight 35 inches, and the distance between the grooves 3 and 6 would be about eight and one-half inches.

The end-plate 1, shown in Fig. 2, is one of a pair. Because each of the end-plates is identical in form and construction only one has been shown here for the sake of simplicity. The endplate I has a circular opening 8 in its center portion in order that the end-plate I may be mounted upon the spindle l. Stretched across the circular opening 8 are two helically coiled springs 9-9 which are attached to the endplate I by means of four rivets Ill.

To assemble these stationery guiding instrumentalities into a complete assembly, as shown in Fig. 3, a supply roll ll of unperforated multlcopy stationery I2 is placed upon the spindle I. This stationery l2 consists of individual sheets of paper l3 interleaved with carbon sheets I l. The stationery is usually wound on a cardboard roller (not shown) in order to make a compact 56 The reason for having a plurality of 25 a supply roll II. In placing the supply roll II upon the spindle I,'all that is necessary to do is to simply push the spindle I inside the cardboard roller (not shown) of thesupply roll II.

After supply roll I I has been placed upon spindle I, an end-plate I is mounted upon one end of spindle I, such as the left end, by inserting the end of spindle I through the opening 8 in endplate I and between springs 9-9. The end-plate I is then pushed against the left edge of supply roll II thereby enabling springs 9-9 to fit into,

, or co-act with, groove} in spindle I thus securely holding end-plate I firmly against the edge of supply roll II. The other end-plate I -is then mounted in a similar manner upon the other end (the right end) of spindle I. In this case,

springs 9-9 will fit into groove 6 in spindle I.

As was stated above, it is assumed that the width of supply roll II is eight and one-half inches and that the distance between grooves 3.

and 6- is about eight and one-half inches. In other words, grooves 3 and Ii are so located as to cause end-plates 1-1 to be held in close juxtaposition with the edges of supply roll II.

In Fig. 3, it can be seen that the diameter of each of the end-plates 1-1 is greater than the diameter of the supply roll II. This serves to prevent anyof the individual sheets of the multicopy stationery I2 from slipping or sliding over the edge of supply roll II. As a result, the individual-sheets of stationery I2 are held in correct lateral alignment on the cardboard roller (not shown) of supply roll II and, when supply roll II is rotated by the feeding of stationery I2 during printing operations,end-plates 'I'| will serve to guide stationery I2 from the supply roll II and will prevent stationery I2 from weaving sidewise and becoming laterally misaligned.

If it should be desired to use a supply roll of a different width, such as eight inches, the procedure (after placing it upon the spindle I) would be to mount an end-plate 1 upon one end, such as the left end, of spindle I in the manner described above. This time, however, the endplate I should be pushed over on the spindle I sufllciently to allow springs 9-9 to fit into groove 4. The other end-plate 'I would then be mounted on the right end of spindle I and should be pushed over closely against the edges of the supply roli. This would enablesprings 9-9 to flt into groove 5, thereby holding both end-plates 1-1 in close juxtaposition with the edges of the supplyroll. 5

In this manner, the plurality'of grooves in each end of the spindle I enable the position of the end-plates 1-1 to be varied, or adjusted, in accordance with variations in the widths of the supply rolls used. The reason for having a plu- 10 rality of grooves in each end of the spindle I instead'of Just one end is to enable a supply roll to be centered on spindle I regardless of the .width of the supply roll.

It is to be understood that only two grooves 15 have been shown in each end of the spindle I for the sake of simplicity. The invention is not limited to only two, but includes as many as are needed for the different widths 0! supply rolls that are desired to be used in a particularly 2o printing machine. Likewise, the invention is not limited to circular end-plates but extends to endplates of different shapes. The use of helical coiled springs has been shown as the preferred embodiment of the holding means for holding 25 the end-plates on the spindle. Some other type of springs or similar holding means could be used without department from the scope of the invention which is to be determined only by the appended claim.

- What is claimed is:

A device for holding a roll of stationery-upon a roller having a circumferential groove in and near each end, said device including apparatus for reducing lateral misalignment of the stationery, said apparatus comprising flat endplates having openings therein for enabling the ends of the roller to b'e'passed through the endplates, each of said end-plates having a larger diameter than the roll of stationery, and instru- 40 mentalities for holding the end-plates in place upon the roller and in close juxtaposition with the edges of the roll of stationery, said instrumentalities including a plurality of helically coiled springs attached to each end-plate and 5 stretched across the opening in each end-plate for engaging with the grooves in the roller.
