This invention relates to improvements in manifolding machines such, for example, as autographic registers, and in relation to some of its more specific features it relates to improvements in feed-controlling mechanism for the record strips or .work sheets of such machines.

' It is a general object of the invention to provide an improved, quick operating machine of the class mentioned which may be used to advantage in taking orders over the telephone where one hand is engaged in holding the telephone receiver, and for similar uses whereit is important that a record be quickly and accurately transcribed and the work sheet fed forwardly so as to eject the inscribed ticket or leaf and to place another in inscription-receiving position with a minimum of time and eifort.

A further object is to provide an improved strip feed mechanism for machines ofthe class mentioned, whereby a. length of record strip equal to the length of a single work sheet or ticket can be more quickly fed forwardly by a single uni-directional stroke of the feed mechanism by the operator.

Another object is to provide in machines of the class mentioned an improved strip-feeding mechanism,'whereby a transcribed sheet or ticket may be'automatically jarred from the machine by the reaction or rebound of the feedin mechanism following a feeding operation t ereof.

Still another object is to provide in machines of the class mentioned an improved reciprocal feed actuating mechanism operating through recoil or rebound of engaging parts so as to effect automatically a feed actuation.

Another object of the invention is to provide in machines of the class mentioned an improved strip-feeding mechanism having an improved stop arrangement for preventing overthrow of the strip feed.

Another object is to provide, in machines of the class mentioned, an improved mechanism for limiting to a predetermined value A furtherobject is to provide" in machines mechanism for automatically arresting operation of the feed mechanism at the end of each feeding cycle so as to prevent overthrow of the feed.

Other objects will be in part pointed outin the following detailed description of certain illustrative but preferred embodiments of-the invention and will be in part obvious in connection therewith. v

The invention accordingly comprises the features of construction, combinations of elements, and arrangement of parts, which will be exemplified in the construction hereinafter set forth and the scope of the application of which will be indicated in the claims.

For a more complete understanding of the nature and objects of the invention, reference is had to the following detailed descriptionof V the illustrative embodiments and to the accompanying drawings in which:

Fig. 6 is a sectional view similar to that of Fig. 2 but disclosing a modified form'of the invention; and

Fig. 7 is an elevation of a detail of the construction.

Referring to the* drawing for a detailed description and firstto the embodiment of tion to this type of machine of an embodiment of the invention. This autographic register may be provided with the usual casing 10 which-mav be formed atone end with vum an interior compartment 11 for the reception of a supply of blank record strips A. This supply ma be made u in the form of a zigzag folde supply pa A in which a plurality of the record strips are folded together in zigzag form in the pad. Also, at the forward end of the register casing, a storage compartment 12 may be provided for the reception in folded condition of one of the record strips A after it has been written upon in the ordinary course of business. A platen or writing bed 13 is provided over which the stri s are led in relatively superposed manifol ing relation with each other. Also, at a suitable position relatively to the platen, supporting means may be provided for one or more transfer sheets such as carbon paper whereby the transfer sheets may be interleaved with the record strips in order to transfer the inscriptions to the underlying strips.

Strip filing or folding mechanism, such for example as that disclosed by the atent to Clarence L. Johnston #1,658,12 dated February 7, 1928, for autograph-i0 registers, may be utilized for causing one or more of the inscribed strips to be folded in zigzag formation in the filin compartment 12 as indicated in Fig. 1 at As disclosed in the Johnston patent, it will be understood that each of the record strips may have one or more series of feeding or form aligning aperture's arranged therealong adjacent the edges and also a series of strip folding apertures may be provided in one or more 0 the record strlps for the purpose of cooperating with the folding mechanism in folding the strip in the compartment 12. The general construction of the strip feeding and filing mechanism and the arrangement thereof with reference to the platen and to the supply and filing compartments may be similar to that disclosed in the Johnston patent mentioned.

There are, however, certain improvements embodied in the strip feeding mechanism which will now be described. A feed shaft 14 is rotatably mounted in suitable bearings carried by the machine and carries a pair of :paeed feed disks 15 only one of which is own in the drawing. Each of the feed disks is provided with a peripheral enlargement or lug 16 similarly arranged on the two disks and having an outer cylindrical contact face in continuation of the periphery of the disk. A cylindrical feed roll 17 overlies the feed disks having its peripheral surface engaging that of the disks.

he feed roll 17 may be mounted in a roll housing 18 pivotally mounted for swinging movement by means of arms 19 ivoted to the casing at 20. The feed roll is preferably mounted for up and down movement in the housing the upward movement thereof being yieldingly resisted as by means of sprin 21 in a manner similar to that disclosed in the Johnston patent mentioned. A pinion 22 is mounted on one end of the feed roll or roll shaft and meshes with a tooth gear 23 carried by and rotatable with the feed shaft 14 so as to cause the feed disks and feed roll to rotate in unison.

The feed shaft 14 preferably projects through the casing as shown in Fig. 2 being provided at the extension thereof with a clutch head 24 having a recess in which is slidably mounted a plunger pin or dog 25 yieldingly urged outwardly by means of a spring 26. A clutch pinion 27 is rotatably mounted on the outer end of the clutch head being retained in position by means of a retaining plate 28 screwed to the clutch head.

As shown in Fig. 3, the inner face of the clutch pinion 27 is preferably formed with a slot 29 curved concentrically with the axis of rotation of the pinion for the reception of the adjacent end of the clutch dog 25. This slot is relatively deep at one end thereof forming a tooth or shoulder 30 against which the clutch dog may engage upon rotation of the clutch pinion in feeding direction, thus causing the feed disks 15 to be rotated in strip feeding direction. .The bottom of the slot 29 inclines upwardly from the shoulder 30 until at its opposite end it lies flush with the adjacent face of the clutch pinion.

As shown in Fig. 2, mounted for reciprocal rotation upon a-stub shaft 31, suitably secured to the machine as by means of a plate 32 is a toothed sector 33 meshing with the clutch pinion 27 and having secured thereto through an integral enlargement a manual operating arm or lever 34. The toothed soctor may be formed as shown with an integral hub 35 having an integral collar 36 merging with the sector. Resting against this collar and mounted for rotation on the hub 35 is a washer or actuating collar 37 having a concentric slot 38 (Fig. 5) positioned so as to open inwardly toward the hub 35. The lug 39 is mounted upon the hub 35 and received in the slot 38 of the actuating collar so as to contact with the opposite terminals of the slot so as to compel rotation of the hub and collar in unison. The lug 39 is of less extent circumferentially than the slot so as to permit a certain amount of relative or lost rotary motion between the collar and the hub. A coiled spring 40 surrounds the hub and is anchored at one end to the actuating collar 37 and'at its opposite end it is anchored to the frame of the machine or to the plate 32 as shown. A lug or'arm 41 extends outwardly from and is mounted upon the actuating collar 37 as shown in Figs. 1 and 5 and, as shown, preferably lies in the plane of the collar. A sto 42 is mounted in position to engage with t 1e lug 41 and may be suitably mounted on the machine, being shown as carried by the plate 32.

V Formed upon the clutch head 24 or upon the feed disks.

any other suitable part which rotates or moves with the feeding mechanism is a lug or tooth 43. Also a detent or pawl is arranged so as to be movable into or out of engaging position with the lug 43 so as to limit positively the forward feeding movement of In the embodiment shown, this feed limiting detent is indicated at 44" and is carried by the sector 33 moving *with the latter toward and away from its feed limiting position.

In" order to prevent retrograde rotation of the feed disks 15, a pawl suitably mounted on the casing may be provided and positioned so as to engage the teeth of the gear 23 as shown in dotted lines in Fig. 1. This pawl is so positioned as to freely permit forward rotation of the feed disks but to obstruct reverse rotation thereof and may be held in engaging position by a biasing means such as.

gravity or a spring.

One illustrative embodiment of the invention having been described, the operation will now be clearly understood and may be summarized as follows.

The record strips A having been loaded into the machine in. a manner well understood in the art an inscription. may be made on the top record strip over theplaten 13 which is transferred to the lower strips by the carbon sheets. The lower strip may be folded into the compartment 12 by the folding mechanism as above suggested. When the inscription has been entered, the operating lever 34 is moved by the operator from the full line position shown in F ig. 1 to the dot and dash line position in the same figure." During this movement, the feed disks 15 and rolls 17 are operatedthrough a single feeding cycle which is preferably sufiicient in extent to feed the strips forwardly about the length of a single form sheet or ticket into which the stri' s are tance slightly-less than the length of a form sheet or ticket and the feeding of the strip will be completed by a supplemental feeding action as described below.

" Aligning of the strips longitudinally is of fected by engagement of the feed disks 15 in the strip aligning apertures'of the strips as said apertures come into alignment with the feeding grip betweenthe disks and the feed roll '17. The strips may again be started when the apertures are thusialigned with the feeding grip by the action of the starting lugs 16 which engage the strips against the feed roll 17 at points thereof out of longitudinal alignment with the form aligning apertures. Also, the folding action on the file strip is accomplished during the feeding movement all as fully described in the Johnston patent referred'to.

As the feed lever in its feeding movement predetermined position.

approaches the forward end of its feeding stroke, the detent or pawl 44 approaches the surface of the clutch 'head 24 and as the limit of the feeding stroke is reached, the detent engages against the shoulder or tooth 43 of the clutch head as shown in Fig. 4. This action not only limits the forward movement of the feed lever but also positively stops the forward feeding action of the feed disks in a This stop or feed limiting position occurs just prior to the time that the form sheets or tickets are fed out of the grip of the feed disks and feed rolls. The strips are completely fed beyond the feed grips by the supplementary feeding action described below.

During this movement of the reciprocal operating arm 34, the stress of spring 40 is increased and at the end of the strip feeding cycle of the feeding mechanism, the lever 34 may be released whereupon spring 40 carries the feed lever and sector 33 to its initial position in a quick return movement.

During this return movement, the clutch pinion 27 is reversely rotated idly and the end of the clutch dog 25 rides from its position in contact with the lug 30 upwardly on the inclined bottom of the slot 29. When the clutch pinion has thus made a complete reverse rotation, the dog is projected again by the spring 26 into position to engage shoulder 30. It will thus be observed that the angular distance between one engaging position ofthe shoulder 30 and dog 25 and the next successive engag ing position therebetween is the same as the angular movement of the feed disks in their feeding action to feed the strips forwardly the length of a single form sheet or ticket. This angular distance in the embodiment shown is 360 or a complete revolution of the left terminal of the slot 38, as viewed in Fig. i

5. When the movement of the actuating collar is suddenlyarrested by engagement of the arm 41 with the stop 42, the lug 39 is carried through the momentum of the connected parts against the opposite terminal of the slot 38, that is the right terminal as viewed in Fig. 5, this now being the relative disposition of the parts as disclosed in'this figure. As the lug 39 thus engages the terminal of the slot 38,there is a rebound in the reverse direction of the sector caused by the engaging parts. In other words, the terminal of the slot may be said to act asan anvil and the lug 39 to a is clutch pinion 55. The clutch pinion is act as a hammer which rebounds due to the elasticity of the engaging parts.

This rebound of the sector 33 effects a supplemental feeding action of the feed disks 15 because at the time of the rebound the clutch dog 25 has moved into engaging position with the lug 30. This supplemental feeding action is sufficient to feed the form sheets or tickets which have just beeninscribed beyond the feed grips and said tickets may then be detached and disposed of as desired.

During the rebound action of the sector, as described, movement of the sector in the supplemental feeding action may be limited by the slot 38 because after a predetermined movement, the lug 39 contacts with the opposite end of the slot, that is the left end of the slot as viewed in Fig. 5. In this manner the supplemental feeding action of the strips is limited to the desired amount. With the arrangement described, it will be obvious that the rebound of the sector is not opposed by the spring ,40 and the supplemental feeding action is thus effectually accomplished.

There may also be a rebound between the actuating collar 37 and the stop 42 when the arm 41 engages said stop during the quick return action of the sector as described. The stop 42 thus may act as an anvil and the arm 41 as a rebounding hammer in a manner similar to that described in connection with the lug 39, but such rebound of the actuating collar would be opposed by the tension of spring 40. Even under these conditions, the rebound would under certain circumstances be sufficient to effect the supplemental feeding action mentioned and such action might be accomplished independently of the elongated slot 38 The embodiment of the invent-ion disclosed in Figs. 6 and 7 is similar to that above described and corresponding parts are designated by the same reference numerals. However, some parts are modified and are designated by different numerals. The sector 46' corresponds to sector 33 and is similarly mounted to the latter upon a stub shaft 47 carried by the casing 10, having a hub 48 provided with a collar 49 and to which the reciprocal operating lever 34 is attached. The actuating collar 50 is similar to the collar 37 of Fig. 2 and is similarly mounted upon the hub 48 having ail elongated slot 51 in which thelug 52 on the hub 48 is positioned. The arm or lug 53 is carried by the actuating collar 50 and is arranged to engage with a stop (not shown) similar to the stop 42 already described. The operation of the actuating collar to effect through the sector 46 a supplemental feeding action is the same'as that described above. a

The clutch head 54 is fixed to the end of the feed shaft 14 and positioned adjacent thereto formed on its face adjacent the clutch head with an inclined slot 56 similar to slot 29,

which engages the clutch dog 57 carried by the clutch head and urged into engaging position by means of a spring 58.

In this embodiment the sector 46 is formed at its inner side with a cam 59 having an inclined face. A stop pin 60 with an attached plunger head 61 is mounted in a tubular casing 62 attached to the machine. The plunger head 61 is positioned so as to be engaged by the cam 59 and is urged outwardlytoward said cam by a spring 63. The stop pin 60 is positioned so as to be projected between the spokes of the gear 23 or in an aperture thereof.

As the feed lever 34 is moved forwardly by the operator,'the cam 59 engages the plunger 61 forcing the stop pin inwardly to engage the wheel 23, thus stopping the feeding movement at a predetermined point as in the case of the detent 44 when it engages the tooth 43, as above described. In other respects, the operation of this embodiment is similar to that above described and Will be understood without further explanation.

Machines embodying the invention as above described are capable of rapid operation without much effort or concentration on the a part of the operator. This is partly on account of the fact that the complete feeding operation to feed the form sheets or tickets forwardly can be accomplished by a single pull or push in one direction upon the lever 34. These machines are, therefore, particularly well adapted for the reception of telephone orders or instructions where one hand is ordinarily employed in holding the receiver.

Also the improved machine as above described is well adapted for being countersunk or let down into the surface of a table or desk so that the top of the machine may lie substantially flush with the top of the desk in convenient position for receiving an inscription by the operator. When a machine is thus mounted, the upper end of the operating lever Will be positioned above the top of the machine and desk and the feeding operation can be readily accomplished since the operator can grasp the operating lever above the table during the operative stroke.

Since certain changes may be made in the above construction and different embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.
