14 Claims.

This invention relates to typewriting machines and more particularly to typewriting machines employing form stationery, such as coupon stationery.

One feature of this invention is the provision of means for quickly feeding a form sheet out of a typewriter after it has been typed upon.

Another feature of this invention is the provision of means for alining the next following 0 form sheet into position for typing thereon.

The invention may be best illustrated by applying it to a teletypewriter used for printing on coupon stationery. It is to be understood that the scope of the invention is not limited to teletype- 5 writers, but is, in general, applicable to all typewriters. Neither is it to be limited to coupon stationery, but it extends broadly to all types of stationery including single sheet stationery, multicopy stationery, and manifold stationery.

0 In many types of businesses, it is frequently necessary to print upon a large number of coupons by means of teletypewriters. The coupons usually used comprise simple printed forms upon which information is typed. Such coupon stationery usually does not have perforations there-' in for feeding and alining it because, in general, typing is made upon only a small portion of each coupon so that accurate registration of the typing upon horizontally arranged lines is not necessary. Heretofore, the stationery was fed through teletypewriters in accordance with line-by-line typing operations. Although only one or two lines may be typed upon an individual coupon, it has been necesasry for an operator to feed the 3 stationery through a teletypewriter only at the slow rate of one line at a time. In order to feed a coupon out of a teletypewriter after it has been typed, it has also been necessary for an operator to feed the coupon out at the rate of only one line After having taken a typed coupon out of a teletypewriter, in order to type upon the next following coupon, it has been necessary for an operator to exercise care in order to stop the feeding operations so that the first line which is typed upon the next coupon will be in the proper position.

The purpose of the present invention is to speed up such operations in order to decrease the time lost in the alining operations both by the operator and the teletypewriter. The invention comprises feeding means for feeding stationary through a teletypewriter during the typing of a coupon, ejecting means for rapidly feeding stationery out of a teletypewriter after a coupon has been typed upon, and an alining arrangement for automatically bringing the next following coupon into the proper position'for typing thereon.

The feeding means feeds stationery by means of the co-action of a driven platen with a pair of idler pressure rollers having a common axle. This feeding means feeds stationary through a tele-. typewriter at the rate of one line at a time because it operates in accordance with line-by-line typing operations.

The ejecting means rapidly feeds stationery out of a teletypewriter by the co-action of another pair of idler pressure rollers, also having a common axle, with two other pressure rollers having a common axle which is continuously driven.

The aligning arrangement depends upon the use of a strip, or roll, of coupons having openings therein at spaced intervals. These openings are so located as to pass between the rollers of the ejecting means, but not between the rollers of the feeding means. When the openings come between the rollers of the ejecting means, the rollers will become out of contact with the stationery and the ejecting of the stationery will cease. Due to the proper location of the openings, the stationery will stop in the proper position for typing upon the next coupon and no additional alining will be required.

Control and disabling means are provided for controlling the operation of both the feeding means and the ejecting means and for disabling either of them.

The invention will be better understood from the following detailed description with reference to the accompanying drawing in which:

Fig. 1 is a three-dimensional view of a preferred form of the invention;

Fig. 2 is a cross-sectional view of the arrangement shown in Fig. 1; and

Fig. 3 is a three-dimensional view showing how stationery may be alined.

In considering the following description, it should be kept in mind that the description is applicable to both a teletypewriter at the transmitting end of a telegraph line and to a teletypewriter at the receiving end. Both machines are similar in construction and operation. This description is given for purposes of illustration only and the invention is not to be restricted to the specific construction disclosed herein.

Figs. 1 and 2 represent only that portion of a teletypewriter 'which is necessary for the purpose of illustrating the invention. In these figures the apparatus is shown as being in the process of ejecting stationery from a teletypewriter. Since the ejecting means is shown to be in operation, the feeding means is shown to be disabled, or non-operable. Coupon stationery 1 is represented as coming into the teletypewriter from a supply (not shown) located near the lower right corner of each of Figs. 1 and 2. From this supply, stationery 1 passes between retarding rods 2, between driven platen 3 and guides 4, 4, between platen 3 and

guides

5, 5, and is then fed out of the teletypewriter by the co-action of

idler pressure rollers

6, 6 and driven pressure rollers"7, '7.

The ejecting means will now be described in detail and its operation explained. It may be assumed that an operator, having finished typing upon a coupon, wishes to eject the typed coupon from the teletypewriter and to bring the next following coupon into position for typing thereon. In order to do this, the operator transmits a predetermined signal combination or eject signal. In response to this eject signal, link 13 of both the transmitting teletypewriter and the receiving teletypewriter or teletypewriters will be pulled down. Any of several methods may be employed for transmitting the eject signal and for pulling down link 13. The pulling down of link 13

pulls rollers

12, 12 away from platen 3, thus disabling the feeding means as will be explained hereinafter. At the same time,

idler rollers

6, 6 will be pushed against driven rollers '7, '7.

Rollers

6, 6 are locked in this position by detent 15 which also maintains them under pressure as shown in the drawing by means of its spring 18. Rollers '7, '7 have a common axle 14 which is continuously driven by any convenient means such as the power supply which operates the teletypewriter. Unlike platen 3 which can rotate only one line space at a time, rollers '7, 7 are rotating continuously. Therefore, the speed at which stationery 1 will be ejected from the teletypewriter depends upon the speed of rotation of rollers '7, '7. This constitutes a saving in operating time because a typed coupon was formerly fed out of a teletypewriter at the rate of only one line space at a time. This former method not only was slower, but also required more work on the part of an operator.

The alining arrangement will now be described and explained. It will be observed from the drawing that stationery 1 has a V-shaped notch 8 cut out from each margin along the line of division between two contiguous coupons. The use of V-shaped notches instead of openings of some other shape has been shown simply to illustrate one embodiment of the invention.' This shape of opening was chosen because it does not unnecessarily disfigure a coupon. The scope of the invention includes stationery having openings of other shapes and locations. When stationery having openings shaped and located as shown in the drawing is used, it is necessary that

idler rollers

6, 6 be so spaced on their common axle 16 that the distance from the inside end of one roller 6 to the inside end of the other roller 6 is a little greater than the distance between the points of the V-shaped notches 8 in stationery 1. Due to this construction,

rollers

6, 6 will travel only over that portion of stationery 1 wherein notches 8 are located. When a pair of

notches

8, 8 comes between

rollers

6, 6 and '7, '7 (as is indicated in Fig. 3), a stationery 1 will become out of contact with

rollers

6, 6 and '7, '7 and will cease to be ejected. In order to avoid the danger of further ejection of stationery 1 due to its being carried forward by its momentum and thus being brought into contact with

rollers

6, 6 and '7, '7, it

is advisable to employ some vsort of speed checking device, such as retarding rods 2.

Rollers

6, 6 and '7, '7 are so located that, upon ceasing to be ejected (due to the appearance of

notches

6, 8 between

rollers

6, 6 and '7, '7), stationery 1 will stop in the proper position, with respect to type bar 9, for typing upon the next coupon. No further alining of stationery 1 is necessary. This does away with the need for alinement attention by an operator, thereby effecting a saving in operating time. An additional saving in operating time is due to the fact that the coupon which follows an ejected coupon is stopped in position for typing thereon so that an operator need no longer feed an untyped coupon up into place at the slow rate of only one line space at a time.

When an operator wishes to resume typing he may do so by printing any character. This will cause link 10 to be pulled down by the printing bail (not shown) of both his teletypewriter and the receiving teletypewriter or teletypewriters. The ejecting means will now be disabled because

idler rollers

6, 6 will be lifted up out of contact with driven rollers '7, '7. The same result may be obtainedby manually depressing key 11. Although rollers '7, '7 may keep on rotating, their rotation without the co-action of

rollers

6, 6 is insufiicient to eject stationery 1.

At the same time that the ejecting means is disabled, the feeding means is rendered operable and will now be described and explained. When link 10 is pulled down, it unlocks detent 15 from the position shown in the drawing and shifts it into a new position (not shown). At the same time,

idler rollers

12, 12 are pushed against driven platen 3 which has its axle 17 connected to the power supply of the teletypewriter. Rollers 12, 12' are locked in this position by the new position of detent 15 and maintained under pressure by means of spring 18. Stationery 1 can now be fed through the teletypewriter by the rotation of platen 3 in accordance with line-by-line typing operations.

Rollers

12, 12 are so located upon their common axle 16 that the distance from the outside end of one roller 12 to the outside end of the other roller 12 is less than the distance between the points of the V-shaped notches 8 in stationery 1. Since notches 8 are located in the margins of stationery 1, it is evident that they do not come between rollers 12. 12 and platen 3. Therefore, the feeding means is not directly afiected by notches 8.

After a coupon has been typed upon as much as is desired and the operator wishes to eject it and bring an untyped coupon into position for typing thereon, the operator transmits a predetermined signal combination or eject signal. This eject signal causes link 13 to be pulled down thereby causing

rollers

12, 12 to be pulled away from platen 3. This disables the feeding means because the rotation of platen 3 without the coaction of

rollers

12, 12 is insufl'icient to feed stationery 1. As was explained above, this eject signal causes

rollers

6, 6 to be pushed against rollers '7, '7 thereby rendering the ejecting means operable. Since rollers '7, '7 are continuously driven, they will co-act with

rollers

6, 6 and rapidly feed the typed coupon out of the teletypewriter as is shown in Figs. 1 and 2. Also, the next following coupon will be alined into position by the alining arrangement as described above.

If an operator wishes to tear oil a typed coupon after it has been ejected, he should first manually depress key 11 which, as has been described above,

disables the ejecting means and brings

rollers

12, 12 into contact with platen 3. This procedure will hold the next following coupon firmly between

rollers

12, 12 and platen 3 thereby facilitating the tearing off of the typed coupon and preventing misalinement of the untyped coupon during the tearing operation. If desired, a tearing edge may be supplied, otherwise the stationery should be perforated along the line of division between two contiguous coupons, as is shown in the drawing. For the sake of simplicity in the drawing, a tearing edge has not been shown. If a tearing edge were desired, a convenient location would be just above axle 14 and just below axle 16, so as to enable stationery 1 to be torn along the line of division between two contiguous coupons.

This use of the device is illustrative of its operation. As has been stated above, the application of the invention is not limited to the use of V-shaped marginal notches. If stationery having openings of other shapes and locations were employed, the apparatus shown in the drawing could be readily modified accordingly. Also, if it were desirable to use stationery having perforations therein for pinwheel feeding, this could readily be done. In short, the embodiment described will serve to assist in interpreting the claims. The claims are not to be restricted to the precise construction disclosed, but are intended to include all changes and modifications employing the principles and features of operation of the invention.
