In, West Orange, N.J., assignors, by rnesne assignments,

to Electronic Associates, Inc., Long Branch, N.J., a

corporation of New Jersey Filed Oct. 3, 1960, Ser. No. 60,067 2 Claims. (Cl. 346138) This invention relates to recording paper or sheets, and, more particularly, to recording paper used as the recording medium of a recorder device.

In one type of recorder device, a variable parameter, such as the on-off time of a machine, is plotted as a function of a standard parameter, such as time, by rotating a drum having recording paper thereon and by marking portions of the paper in response to a voltage developed as a function of the operating time of a machine to obtain a plot of this parameter against time. In such devices it is desirable to secure the recording paper tightly on the surface of the drum and to be able to remove the recorded medium and to substitute a new one therefor with ease and simplicity so that periods wherein it is desirable to record data are not taken up with changing from one record paper to another.

It is an object of the invention to provide a recording paper for the rotatable drum of a recording device wherein the paper can be securely fastened to the surface of the drum along an axis parallel to the rotating axis of the drum so that errors are not induced into the recorded markings by misalignment of the recording paper thereon; and also, it is a further object of the invention to provide a recording paper which is both installable on and removable from the surface of the drum 'with ease and simplicity.

Another object of the invention is to provide a recording paper which after it becomes a recorded medium can be indexed and bound in a permanent record book for future reference.

Accordingly, the recording paper of the invention is fabricated with such dimensions and configuration as to enable the recording paper to be wrapped around the surface of the rotatable drum, the paper being slightly oversized in the longitudinal direction to facilitate the attachment of the recording paper to the drum and to enable the recording paper to be permanently bound in a record notebook. To facilitate the attachment of the recording paper to the drum, a folded flap with angled sides is provided at one end of the recording paper. The other end of the recording paper may also be provided with angled sides for securing that end of the recording paper in place underneath the leading end of the recording paper forming the folded flap so that the recording paper can be drawn taut across the surface of the rotatable drum and secured in place in a substantially small section of the surface of the drum.

Moreover, a perforated mark is provided in a vertical direction on the recording paper to insure that the folding edge which is used to secure the recording paper to the drum lies in a substantially vertical direction so that the recording paper can be properly positioned on the surface of the drum. A perforated mark can also be provided on the other end of the recording paper for forming another folding edge, which is more rigid than the paper itself so that it can be inserted underneath the leading edge of the recording paper and secured thereat tightly by a device used to secure the recording paper to the rotatable drum. Additionally, the recording paper can be inserted into a permanent record book by providing suitable openings in either of the ends thereof adjacent the folded edges provided in the recording paper, or alternatively, if desirable, the longitudinal length of the paper can be shortened by removing portions of the recording paper along the perforated mark provided in the recording paper.

These objects and features of the invention will be understood by reference to the following detailed description when taken in conjunction with the accompanying drawing, wherein:

FIGURE 1 is a plan-view of the recording paper of the invention;

FIG. 2 is a three-dimension view partly in section of a rotatable drum having the recording paper shown in FIG. 1 attached thereto; and

FIG. 3 is a side-elevation view of the drum shown in PEG. 2 with a portion of the recording paper cut away.

Referring to FIG. 1, there is shown the novel record ing sheet or paper 10 of the invention. As shown the longitudinal sides 12 and 14 are appreciably longer than the

vertical sides

16 and 18. The longitudinal length of the paper, however, is selected so as to enable the paper to be wrapped around the circumference of a rotating drum 20 (FIG. 2) of the recording device, and the length of the paper is oversized for reasons to become apparent. The vertical extent of the paper, on the other hand, is selected so as to enable the paper to cover a portion of the drum which is traversed by a marking stylus. Intermediate each of the

vertical sides

16 and 18, and the longitudinal sides 12 and 14, are

angled sides

26, 28, 38, and 40.

A perforated mark 22 or series of perforations 24 is provided in a vertical direction and to one side of the junction between each of the

angled sides

26 and 28 provided between the vertical side 16 and each of the longitudinal sides 12 and 14 at the leading edge of the paper. Accordingly, when the paper is folded back on itself on the perforated mark 22 a fiap 30 is provided with an edge 32 along which the paper can be secured in place to the surface of the rotatable drum 20.

In a similar manner, a perforated mark 34 or a series of perforations 36 is provided on the other side of the paper which intercepts each of the

angled sides

38 and 40 provided intermediate the vertical side 18 and the longitudinal sides 12 and 14. Similarly, a flap 42 with an edge 44 is provided at the other end of the paper by folding the paper back on itself at the perforated mark provided therein.

Printed numbers 46 may be provided in a longitudinal direction along one edge of the paper. These numbers may be used to identify each one of a plurality of machines having a variable parameter, such as the respective on-off time of each machine, and numbers 48 can be provided in a vertical direction along one side of the paper to identify a parameter, such as time, against which the variable parameter will be plotted. For example, the on-off time of a plurality of machines can be plotted as a function of time with a suitable recorder device in which electric signals indicative of the on-oif time of each of the machines to be monitored is connected to a stylus disposed adjacent the recording paper on a rotatable drum to obtain a permanent record of the operation of each of the machines over a selected period of time.

A flexible band 50 is provided for securing the recording paper or sheet 10 in place to the rotatable drum 20. The band 50, for example, consists of a strip of metal which is secured at the ends thereof and extends in a vertical direction across the surface of the drum 20. One end 52 of the band 50 is bent back on itself so as to provide a clamp for engaging one end of the cylinder comprising the rotatable drum 20. The opposite end 54 of the band 50 is provided with an opening 56 therein for securing the end 54 of the band to a surface of the drum 20.

A tension bar 58 having an opening 60 therein is positioned with the opening 60 over the opening 56 in the end 54 of the band and over a mating threaded opening 62 provided in the drum for securing the band 50 in place under stress after the end clamp 52 in the band is afiixed to the other end of the rotatable drum. Additionally, the end 54 of the band may be turned back on itself so that it rests on the top surface of the drum 20 and functions to restrain any movement of the band 50 circumferentially or in an outward direction from the surface of the drum.

The recording paper is correctly positioned on the drum with the surface thereof adjacent a stylus by sliding the

angled side

26 or 28 under the band 50 and positioning the folded edge 32 formed along the perforated mark 22 against a leading edge 64 of the band in enfolding relation thereto. The leading edge of recording paper 10 may be adjusted While in this position so as to have the folded edge 32 coincide with the leading edge 64 of the band in order to secure the paper in place in a vertical direction. The paper 10 is then wrapped around the circumference of the drum and the folded edge 44 at the other end of the paper 16 can be inserted intermediate the flap 30 and the surface of the rotatable drum 20 so that both ends of the paper are secured in place by the band 50. It should be noted at this point that by having the

angled sides

38 and 40 at the trailing edge of the paper, the trailing edge can be inserted under the ends of the band 50 wherein the pressure exerted by the band is a maximum with greater facility than if the angled sides were not so provided.

Alternatively, the flap 42 need not be formed along the trailing end of the paper if an

angled side

38 or 40 can be pushed underneath the band; however, by forming the folded edge 44, there is provided a substantially rigid surface, which can Withstand frictional contact With the flap 30 at the leading edge so that it can be positioned adjacent the leading edge of the paper; and moreover, the rigidity of the folded edge enables the trailing edge to be pushed underneath the leading edge and against the pressure exerted by the band so that the paper can be drawn taut across the surface of the drum.

Spaced apart openings 66 may be provided in one or both of the

flaps

30 and 42 initially or after pertinent data is recorded thereon. These openings 66 can be made to conform to the spacing of the binder in a notebook or record book. Thus, after the record of the event is completed the recording paper can be included in a notebook for future reference. In lieu of providing openings in the flap 30, openings can be provided in the flap 42 for securing the recorded paper in a notebook as previously indicated, and the flap 30 can be used as an indexing device for recording thereon pertinent data or indicia such as the date, recording hours, or any other significant data to be made of record in conjunction with the recorded event. Also the size of the recording paper can be shortened as needed by removing the portion of the paper along one or both of the perforated marks.

Having described the principles of the present invention with reference to a particular exemplary embodiment, the scope of the present invention is to be interpreted by the appended claims, and not in any way limited by the particular embodiment as many modifications thereof will present themselves to those skilled in the art without departing from the principles of the invention.
