, control device 13. A yielding contact 45 on lever 35, affords the proper. yielding and essentially perfect electrical contact to assure proper control of the motor 1'7 at such times as it is necessary to have it function. Disclosure of an electric circuit including the motor'and switch elements has not been made for the reasonthat it is not a part of the'invention disclosed and is but a simplematter quite obvious to one skilled in the art. I

In operation, the parts shown are in normal position and condition, which means that treadle 33 is in elevated position as shown in Fig. l, with arm 28 in backward position, permitting clutch 24 to assume engaged condition under influence of spring pressure from the clutch spring. Normal position and condition also means that switch lever 35, because of the-backward position of arm 28, occupies a position such as shown in Fig. 5, while switch lever 36, because of the engagement of pin 43 therewith, under pressure by finger 44 of control device 13 when it is in normal rearward position, occupies a normal position away from lever 35 and consequently in broken circuit relation therewith. The roll of stationery having had its several webs arranged as shown in Fig. 1, with one as propelling web preferably, and the .others occupying merely draped condition, is thusalso normallyready for use of the apparatus.

Of course, the first operation of the operator is to fill in the web forms on the platen 45, by using the typewriter 46, as is usual; After the forms on platen 45, by using the typewriter 46, have been filled in, the typewriter is pushed back to allow knife 47 to raised and the superposed webs on the platen to be disengaged from the hooked aligning pins 48 with which'the apparatus is equipped. 'The raising ofknife 47 is accomplished by means of'treadle 33 which accomplishes the results described, when depressed by the operators foot. With the raising of knife 4'7,

cable 32 draws upon rod 31 and causes fork- 30 to move arm 28 forwardly, thereby moving switch lever 35 to the greatest tilted position shown in Fig. 6, simultaneously therewith, causing clutch yoke 26 to draw upon clutch collar 25 to compress the clutch spring and disengage the clutch 24. This operation therefore frees loose pulley 22, and, because of the snubbing action of web 50 on rollers 52 and 53, allows web control device 13 to move forwardly as the webs are pulled forwardly by the operator in order to bring a set of fresh forms into position. Forward -movement of the control device moves finger 44 from pin 43 and allows switch finger 36 to move to the position shown in Fig. '7, preparatory to a closing of the switch by lever 35 as will be explained shortly. It may be pointed out that belt 23 which is wrapped on loose .pulley22, is attached to control device 13 in some such manner as shown in Figs. 1 and 2, and'that the control device is provided with a-forwardly extending finger 49 which engages the frame of the typewriter to arrest forward movement'of the control device and to permit rearward movement of the type- 'writer to move the control device rearwardly,

also as will be explained presently.

over the aligning pins 48, the control device 13 is now caused to be moved backwardly by releasing treadle 33, which allows cable 32, rod 31,

and arm 28 to be moved rearwardly by the clutch spring functioning to engage clutch 24, and, through block 39, pin 40, socket 41, and lever 35, to close the switch as shown in Fig; 8. The resultant operation is then to start motor 17 and, through gears 18 and 19, and clutch 24, to cause pulley 22 to windup belt 23 as the control device is drawn rearwardly. Rearward movement of the control device is permitted without restraint by the horizontal portions of the webs, because the snubbing action effected by the webs to cause the control device to be moved forwardly when the webs have been drawn manually over the platen, has been overcome due to clamping of the webs by knife 47 in connection with pins 48, the power of motor 1'? being suiiicient to cause thewebs to slip between rollers 52 and 53 as device 13 moves rearwardly. This slippage is the amount which occurs equal to the total backward movement of thecontrol device and actually is the amount of feed given the webs during each cycle of operation 'of the apparatus described above.- .As the control device is caused, automatically,thus-to move rearwardly, the one web 50, which is the taut web and acts to rotate the stationery roll 51, is drawn uponby its assigned rollers or bars 52 and 53 of the control device, thereby unwinding suflicient ofthe webs to reestablish the necessary amount of drape of the remaining webs, preparatory to a repetition of the moving lever 36 to the position shown in Fig. 5,

and thus breaking the circuit and stopping motor 17. The entire sequence .of operations is now repeated as has been described. 7

It may be well to call attention to the fact that the details of construction of the control unit. constitute no part of the invention herein described, inasmuch as these features have already been described in a copending application to which we have referred above. It also may be advisable, to draw attention to the fact that such a power driven mechanism as that which we have just described, is as readily applicable to other forms of the same general control mechanism which are well known and in common use in connection with billing machines of the long established type.

Having thus described our invention what we claim is:

1. In combination with a platen adapted to receive and position a plurality of superposed webs from a source of supply, a web tensioning and aligning apparatus comprising a control device for feeding the webs and adapted to travel toward the platen under manual operation and away from the platen under power operation, a source of power, a power driven means connected with the control device, and a second means functioned upon completion of the manual operation to connect the source of power with the power driven means, all said parts being so arranged and related that feeding of the webs will be accomplished by movement of the control device bythe power driven means.

2. In combination with a platen adapted to receive and position a plurality of superposed webs from a source of supply, a web tensioning and aligning apparatus comprising a control device for feeding the webs and adapted to travel toward and away from the platen under manual and power operation respectively, a source of power, a power driven means connected with the control device, a second means functioned upon completion of the manual operation to connect the source of power with the power driven means, all said parts being so arranged and related that feeding of the webs from the source of supply will be accomplished by movement of the control device by thepower driven means, and a plurality of elements between which the webs are threaded, carried by the control device, snubbing the webs upon movement of the control device toward the platen and allowing slippage of the webs between the elements upon movement of the control device away from the platen.

3. In combination with a platen adapted to receive and position a plurality of superposed webs from a source or supply, a pair of guide rails extending rearwardly from the platen, a web tensioning and aligning apparatus comprising a control device adapted to travel on the guide rails, a plurality of bars on the control device, between which the webs are threaded, said control device being movable toward the platen under manual operation and away from the platen under power operation, a source of power, a power driven means connected withthe control device, and a second means functioned upon completion of the manual operation to connect the source of power with the power driven means, all said parts being so arranged and related that feeding of the webs from the source of supply will be accomplished by permitting web passage between the bars upon movement of the control device by the power driven means.
