This invention relates and, more particularly, mechanisms for feeding a continuous strips Heretofore it was proposed to provide the conwith physical alterations, usually tinuous strips in the form of apertures, which, in cooperation with the feeding disks, would cause the feeding operation of each individual strip tocease when the feeding disk entered the aperture therein. This not only caused the strips to stopfeeding, but also permitted them to move into alignment with each other either by the tendency of the may be accomplished in feeding disk engaging the margin of the aperture to advance the strip, or by reason sion being made'in the pileof strips Such a feed is for causing disclosed in vember 8, 1921. v

It is an object of this invention to automatically restart the feeding of the paper strips, or at least to place the mechanism in. position to restart even though the feeding mechanism is operated intermittently.

In the broader aspects of this invention, this various ways. In the form of the invention herein disclosed, this is done by initiating the operation nism as a result of the cessation of advancing movement of the paper strips, and the arrangement is preferably such that, after the strips have stopped, a predetermined number of idle operations of the feeding means occurs before the. operation of the starting mechanism is initiated and the paper'restarted 'so as to give an opportunity brought into. registrathe present invention, because the J idle operations are limited and definite in number, it

The present invention is illustrated as adapted to the invention described in copending application Serial No. 187,044, which discloses means for feeding and maintaining. registration 01' manifolding strips when used in a typewriting machine.

As shown in the accompanying drawings, the invention is applied to a front-strike typewriting machine having a cylindrical platen l0 mounted in a carriage frame II. The usual feed rollers 12, which are adapted to press worksheet strips against the platen, are dropped in inoperative position when the device of the present invention is used. The platen is rotated lineby-line by a line spacing a ratchet wheel l3 mounted on the shaft l4 carrying the platen and is rotatably mounted in the carriage frame II.

Paper sheets or strips are guided to the platen by a paper table l5. An apron l6, disposed adjacent the platen, causes the paper to follow the curvature of the platen and lie close thereto atthe line of writing H where type bars I 8 strike upon the platen.

The machine has a bail including side arms 2| whichusually supports auxiliary presser rollers engaging the work in advance of the writing line. The arms are locked down by latches 22 pivoted at 23 on the carriage. The feeding mechanism of the present invention is mounted on the bail in place on the auxiliary roller.

a plan view of the device shown I the paper tends to ticns and relieve the mechanism including will rotate the feed The manifolding material used with the present invention comprises a plurality of record strips 24 having forms 25 printed thereon and having interleaved therewith transfer strips or continuous carbon sheets. The strips are pro.- vided with transverse lines of weakness 2! wherey the strips of the pile .can be severed to form sheet lengths.

The pile of strips may be held together in registration by a staple 28 disposed preferably on each weakened tear line 21.

As described in said copending application, creep when being moved around the curved platen, and, to avoid the accumulating of the creep, the pile is provided with physical alterations, and feeding means, which are relatively narrow disks or rollers, are adapted to enter the aperture or physical alterapile of .strips of the feeding pressure so that the creep accumulated therein can be dissipated.

The physical alterations may be of any shape. In the illustrated form, however, they are made as notches 3t disposed in pairs along the lateral margins of the pile. The pile of strips is advanced by a pair of feeding disks 32a, 32b engaging the pile, one at each side of the machine, and located in longitudinal alignment with .the notches 3|. The feeding disks may be of any suitable material capable of frictionally feeding the strips and are carried by a rod 33 mounted in a pair of at 35 on the arms 2| iliary roller rod. The

in place of the usual auxrod is secured against rotation by screws 33a threaded through the arms' into the ends thereof, see Fig. 3.

The arms 34 extend rearwardly and are provided with springs 36 connected to a bar 37 on the machine so that the rollers are yieldingly pressed against the platen and the pile of papers carried thereby.

To keep the bail arms 2! from rising as a. re sult of the pressure of the rollers 32a, 32b against the platen, they are provided with a pin 38 engaging a notch in the locking arms 22 referred to above.

After the manifolding pile has been fed around -the platen and under the pressure disks 32a,

3%, the rotar movement of the platen will cause the pile of strips to advance line-by-line with the platen until notches ll reach the bite of the rollers 32a, 32b, at which time the rollers enter the notches and relieve the pile of strips from feeding pressure. The strips are thus enabled to shift to relieve the bunch formed therein.

In this position, the movement of the platen rollers but will not, of course, advance the strips.

To insure against the platen inadvertently advancing the pile of strips while the disks'fla, 32b are located in the notches II, a' drag plate 3! is located between the platen and the pile of not advance the stri carried on the pins 38 of plate '30 is provided with Inasmuch as the feed means inoperative at each form-length interval, some arms 34 which are pivoted e anew h 3 a i flib y e r nsfth a p i'iSedJi Usuallyj an, operator' applies suiljlcient 5 2 to regulate the friction drive.

The actuator for releasing the detent can be operated in many ways to release the starter roller when it is desired to again render the feeding means operative.

In the present preferred form of the invention, the detent is released, through the control of a suitable feeler mechanism which engages the paper, in response to cessation of the advance of the paper during feeding operations of the platen. This will insure that'the starting means will not be operated during the normal intermittent operation of the advancing means, but will operate only at form-length intervals when the feeding means is inoperative to feed the strip.

This control is accomplished in the form of the invention shown in Figs. 1 and 2 by having the feed roller 32!) formed with an outwardly A extending hub 80 provided along its edge with a plurality of cammin'g surfaces 8|. In the preferred form of the invention, the cams are spaced around the hub at line space intervals.

A feeler sleeve 82 is loosely mounted on the stationary rod 33 and extends into a recess 83 formed in the end of the hub. The sleeve is provided at one end with a projection 82a carrying aisoft rubber roller 84 which is adapted to engage the strip and be driven thereby so as to-- rotate the sleeve when the strip is advanced. A

trip device, having a sleeve 85 withan integral collar 88, is mounted to slide longitudinally of the sleeve 82 with the end oi thesleeve 1! also entering the recess in the hub. The sleeve II is provided with a cam follower" whichis held in engagement with the cams. by means of aspring 88 interposed between. the collar N'- of the trip anism for the detent is inoperative to release the latter during normal advancing of the strip. The feed rollers will advance the strip line-by-line and the feelerroller, which is driven by the advancing paper, will, of course, rotate simultaneously with the feed roller. v When the feed roller engages the feedv arresting notch in the paper, the strip will not be advanced even though the feed rollers are rotated by the feeding means. The feeler roller, being driven by the paper, will not rotate. Further operations of the feeding means, while in inoperative advancing relation with the strip, will cause the feed rollers to rotate while the feeler roller remains stationary.

According to the present invention, the rela tive rotation between these elements is used to release the starting mechanism. During the initial rotation of the feed roller 32b in inoperative advancing relation with the strip, the hub 80, rotated thereby, will cause the cam formed thereon to rotate with respect to the follower on the sleeve which is held against rotation by the feeler roller engaging the stationary strip. The cam will shift the trip device against the action of thespring 88 and into engagement with lever 12 of, the actuating mechanism. for the detent.

7 Movement of the arm 12 to the right, as shown in Figs. 3 and 4, will cause the lever arm 65 to engage the front edge of the 'o' ning 63 and raise the detent about thepivot i out of engagement with the notch, so that further operations of the feeding means will cause'the starter roller to be rotated and engage the strips to advance them as shown in Fig. 8.

. As shown 'in Fig. '7, the detent, upon being released, is also bodily moved forward and held device and .the projection 02a onthe end of the feeler sleeve. The cami'ollower has a projection 89 which extends into aslot SI formed in the feeler sleeve to prevent relative rotation of thewhile permitting longitherealong. A pair of.

Itwill be seen that the starter mechanism is automatically thrown into action, by a predetermined operation of the feeding mechanism after it has been made inoperative to advance the strips, to the feed of the strips without an operator being present. I

In some instances, the pressure of the feeler roller resting on the paper, at it passes over the platen, may be suiilcient to advance the strips platen even though the feed rollers are the notches in the form. In the shown in Figs. 9 and 10, is avoided by disposing the feeler that it engages the paper to be driven this difllculty roller so thereby at a point remote from the platen.

In this form of the invention, an arm II is disposed between the collar 82 andthe projection "a on: the of the sleeve 82. 'The arm is pivotally'moimted on the rod and has-at its outer roller 04' rotatably will carry the feeler roller so engages the advancing strips and is ro- The-feeler-rollerhasagear ll gearedi thrmigh an intermedistejgear ll carried y he to the teeler'roller 'to be rotated J is now free to turn with sleeve thereby.

The gearing is such that the sleeve 82 will be rotated in unison with the feed rollers during an advancing operation.

when the feed rollers engage the notches so that the advance of the paper is arrested, the feeler roller willno longer the feed rollers in inoperative advancing position will cause relative movement 80 and sleeve 82 and associated trip device will be operthe notch in the starter roller as in the previously described form of the invention to automatically render the feed means operative again to feed the strips.

In order to insure that the feeler roller will be driven by the paper, a supporting roller 99 is mounted on a rod I on a projection of the arms 34' so as to be disposed beneath the paper. The weight of the pivoted arm will cause the the paper and press it against the supporting roller. This will insure a satisfactory driving engagement between the strip and the feeler roller.

'Variations and modifications may be -made within the scope of this invention and portions of the improvements may be used without others.

In a manifolding machine having a platen tive for strip advancement number of ineffective operations of the feeding I over which a plurality of superposed stripshaving feed-arresting, form-registering apertures therein are advanced; feeding means including feed rollers and operative upon the material of the strips for advancing gaged in the apertures in the strips, one of said feed rollers having a hub thereon; means for supporting said feed rollers in cooperative relation with the platen; a feeler mechanism mounted on the feed roller support comprising an arm carrying a feeler roller in spaced relation to" the platen and contacting the strips so as to be rotated by advancement of the strips, a sleeve rotatably mounted on the feed roller support and extending into cooperative relation with the hub on the feed roller, and means carried by the arm for connecting the sleeve to the feeler' roller to be rotated thereby; a trip mechanism carried by the sleeve and adapted to be moved by the hub upon relative rotation between the sleeve and the hub; a starter mechanism for again making the advancing means operative to feed strips; and detent means for holding the starter mechanism in inoperative position, the continued operation of the feed rollers during the period that it is in inoperative relation with the strips, causing relative movement between the hub and sleeve, thereby actuating thev trip mechanism into a position wherein it engages 'and moves the detent means into release position.

20. In a manifolding over which a strip is advanced;

device having a. platen intermittently the strips until enoperating means for-advancing the strip lim -byline a predetermined distance at the lirmt of which the feeding means becomes ineffective to further advance the strip and movement of the strip ceases; and means automatically made operative after a predetermined number of ineffective operations of said feeding means for causing the feeding means to again become effective for strip advancement.

21. In .a manifolding device having a platen intermittentl; operating means for advancing the strip lineby-line, said means cooperating with the strip and becoming temporarily ineffective to advance the strip after the strip has advanced a predetermined distance; and means to automatically cause the feeding means'to again become operaafter a predetermined means. v

22. In a manifolding device having a platen .over which a strip having spaced physical alterations therein is advanced; intermittently operating means cooperating with the strip for advancing the strip line-by-line, said means coacting with said physical alterations and becoming temporarily ineffective to advance the strip after the strip has advanced a suflicient distance to cause the next spaced alteration to move into cooperative relation therewith; and means for automatically causing the feeding means to again become effective for strip advancement after a predetermined number of ineffective operations of the feeding means.

23.- In a manifolding device having a platen over which a strip is advanced; intermittently operating means for advancing the strip line-byline, said means cooperating with said strip and 40 becoming temporarily ineffective to advance the strip after the strip has advanced a predetermined distance; and means automatically made, operative as an incident to cessation of movement of the strip and a predetermined number of operations of the feeding means while in ineffectual feeding relation with the strip for causing the feeding means to again become effective for strip advancement.- 1

24. In a manifolding device having a platen over which a strip having spaced physical alterations is advanced; intermittently operating means for advancing the strip line-by-line, said means coacting with said alterations and render.- ing the feeding means temporarily ineffective to advance the strip after the strip has advanced a distance sufficient to cause the next spaced aleration to be moved into cooperative relation with said means; and means automatically made operative as an incident to the cessation of movement of the strip and a predetermined number of ineffectual operations of the feeding means for causing the feeding means to again become effective for strip advancement.
