Application filed July 28, 1917. Serial No. 183,233.

To all whom it may concern:

Be it known that I, MORITZ BENON, a citizen of the United States, and a resident of the city and State of New York, have invented certain Improvements in Recording Mechanisms, of which thefollowing is a specification.

This invention relates to certain improvements in recording mechanisms, and more particularly in that class or type of such mechanisms which are. more especially designed and adapted for employment in the production of successive records upon record sheets or strips such as are commonly used in connection with monotype type casting machines and the like, and the object of the invention is, in part, to provide a mechanism of this general character having means of a novel and improved description for assuring the uniform and regulated supply of the record sheet or strip to the recording means where such sheet or strip, as is customary, is supplied in roll form, wherebyinjury to the sheet or strip resulting from irregular or non-uniform unwinding of the same from the roll, and improper presentation thereof to the recording means, resulting in destruction of the feed apertures ordinarily provided, or insufficient spacing of the successive records, are effectively prevented; in part to provide feed aperture producing means of a novel and improved description, for use in connection with recording mechanisms such as are provided with feeding means engageablewith feed apertures in the record strip or sheet, where-,

by such feed'apertures may be produced in the previously unperforated strip or sheet in advance of such feeding devices or means to assure substantially perfect or absolute registry therewith and avoid not only loss of registry such as sometimes arises through expansion, contraction, or drying out of the previously perforated or apertured sheets or strips commonly employed, but also the increased cost arising from the expense involved in previously operating upon the sheet or strip for the production of the feed apertures therein, and in part, to a special embodiment of my improvements as an attachment capable of ready and convenient application to recording mechanisms commonly in use, so as to enable such mechanlsms to be improved by the addition of either the improved regulating or supplying means, or saidimproved feed aperture-producing means, or. both, without material change or alteration of the mechanisms as at present in use. 7

The invention consists in certain novel.

features of the construction, and combinations and arrangements of the several parts of the improved recording mechanism,

whereby certain important advantages are attained, and the mechanism is rendered simpler, less expensive, and otherwise better adapted and more convenient and effective for use, all as will be hereinafter fully set forth.

The novel features of the invention will be carefully defined in the claims.

In order that my improvements may be i the better understood, I will now proceed todescribe the inventlon with reference to the accompanymg drawlngs, wherein- Figure 1 is a side elevation of a recording mechanism embodying my invention, showing the application of my improvements to a monotype or similar recording machine by way of example, my said improvements being herein shown constructed as an attachment for such a recording machine, and certain of the operative parts commonly provided in such machines being represented diagraphically Fig. 2 is an elevation of the parts shown in Fig. 1, as viewed from the rear, the suptachment, showing features of construction to be hereinafter referred to, the plane of Fig. 7 is a detached detail view also partly in section, illustrating features of the perforating means which will be hereinafter described;

F 1g. 8 is a fragmentary detail view show- I ing the means for holding the perforators removably in place upon the carrier of the perforating means; 7

Fig. 9 1s a fragmentary perspective view showing features of construction of the bearings for the delivery roll of the attachment,

and a Fig 10 is a fragmentary sectional view showing features of construction of the detent provided for retaining the removable roll holder in position in the attachment.

In these views I have shown my improvements embodied in an attachment espe cially designed and adapted for use in connection with the recording mechanism of monotype type casting machines, but it will be apparent that the invention, while presenting important advantages when embodied in such an attach1nent, is not limited to this special application exclusively, but may with good results be constructed as an attachment for use in connection with machines of various other and different kinds or if desired, may be embodied as an integral part of the machine to which the improved perforating device is to be applied.

The recording mechanism to which my improvements are herein shown applied for use comprises a frame having spaced uprights, as 1, between which is supported for turning movement a driven feed sprocket 2, adapted for positive driving engagement with a record strip or sheet :0, usually of paper, which in the machine to which I have herein shown my improvements applied is fed from a roll, ordinarily provided along and-adjacent to its opposite lateral edges withnparallel series of alined feed perforations, primarily formed in thestrip before its application, in rolled form, to the recording machine, and adapted for engagement by thev teeth of the driven spcoket wheel 2 in such a manner as to permitthe latter to feed said strip accurately and intermittently to and between

guides

3,3, having alined vertically directed apertures adapted tobe traversed by a series of punches, as 4, which are selectively operated as will be hereinafter explained, to produce along the central part of said strip 00, between its oppositely arranged series of feed perforations, a perforated record conforming with the matter to be cast, so that after the completion of such record, said strip may be removed from the recording machine and applied to a casting machine having matrix shifting and casting devices adapted for operation in asubstantially automatic manner under control of said record, to cast the desired matter in type form.

As herein shown, a chamber is provided between the frame uprights 1, adjacent to their lower parts, across which is extended a rock shaft 5 adapted to be rocked in any preferred manner at each depression of any one of the individual keys 6 of a key board which, insuch machines as ordinarily constructed, comprises keys corresponding to the individual characters to 'be recorded, to-

gether with space controlling keys. The particular means employed for actuating the shaft 5 upon the depression of the several keys 6 is obviously immaterial to my invention. As herein shown, the desired opera tion is assured by the employment of a pneumatic cylinder 7, wherein is movable a piston 8, the stem of which is coupled with an arm on shaft 5 atone side ,of the frame, air under pressure being supplied to said cylinder from a supply pipe 9, under control of a valve 10, coupled with a' universal bar 11 .operable'upon depression of either one of the several keys 6 at the, key board to open said valve and admit air under pressure to said cylinder beneath the piston 8 so as to elevate the latter and rock the shaft 5 each time one of said keys (3 is manipulated, a spring or the like being provided for retracting the parts prior to the ClGPIQSSlOlLOffllG next succeeding key.

The recording punches 4, are operated se' lectively from 01: in unison with therocking of shaft 5 under control of the individual keys 6 at the key board was toproduce the desired record in accordance with the order in which the individual keys are depressed, and the means'for accomplishing this result are also immaterial to my present invention and may be such as are ordinarily employed in monotype recording machines, operable upon the depresslon of any particular key 6 to actuate thecorresponding punch 4 exclusively from the rock shaft 5 in such a manner as to produce the desired record perforation in the strip 00 at an arbitrary point in the width thereof, as clearly indicated in Fig. 5 of the drawings. The feed sprocket wheel2 will also be driven intermittently in unison or time with the depressionof the keys 6 by any preferredlmeans, in such a manner that a feeding impulse will be imparted to the strip 00 afterthe depression of each key 6, and corresponding operation of the related perforating punch 4, so as to present an unperforated part of said strip in position to be perforated upon the next succeeding operation of one of said series of punches 4.

pared with plication to as at present muse, for whlch purpose 12, adapted to receive a detachable roll support, whereon is replaceably mounted a roll of paper provided for the production of 'the record, said roll having been previously prefeed perforations parallel with its opposite lateral edges for engagement by the teeth of the feed sprocket 2, but in actual practice, certain disadvantages have arisen from the employment of such previously formed perforations, either on account of their lack of registry with the teeth of the feed sprocket through inaccuracy in the formation of said perforations as originally produced, or through expansion or contraction of the paper after their production, or

from other causes, besides which the production of the feed perforations in the paper prior to its introduction into the machine is obviously a matter of greater or less expense, the avoidance of which assures an important economy and advantage in the operation of such machines.

In carrying out my invention, in orderto avoid these disadvantages, I dispense with the preliminary perforation of the strip and supply an unperforated roll in lieu of the previously perforated roll commonly employed, said unperforated roll being supported in such a manner as to permit the un perforated strip or web of paper to be fed therefrom to a perforating device or means operable under control or in time with the key and feed mechanisms in sucha way as to assure perforation of the strip for the production of one or more feed perforations upon the depression of eachkey of the key board or upon each successive operation of the recording punches 4, or of the intermittently driven feed sprocket, the perforating device employed for the production of such feed perforations being so constructed and arranged that the perforations are produced in the strip in accurate registry with the teeth of the feed sprocket so asto avoid tearing or injury to the strip due to insuflicient registry, and said perforations being produced during the operation of the recording mechanism, so as to avoid loss of registry due to expansion or contraction of the paper, and the increased cost heretofore arising from separately operating upon the paper for the preliminary production of the feed perforations.

In the emb diment of my invention herein shown, the improved perforatingdevice is constructed as an attachment capable of apmonotype recording machines the attachment is provided with a transverse shaft or support 14, the ends of which afford ournals removably engageable in the alined bearings 12, ordinarilyprovided for the reception of the roll support, so that the attachment may readily be applied to the machine without substantial or material modifi cation ofthe latter. This method of connection of the attachment to the recording machine is obviously not material to my invention. I t

Between its journals, the shaft or support 14- is provided with

alined arms

15, 15 adjustably mounted thereon and having at their extremities alined bearings, in which is adjustably held by means of set screws 16,

or the like, a shaft or journal 17, extended transversely across the attachment between the spaced

side frames

18, 18 thereof, to which said shaft or journal is fixedly secured at its extremities, by which means it will be apparent that the attachment is capableof a certain extent of adjustment vertically so as to position its operative parts in any desired relation to the feed sprocket 2 of the recording machine, it being apparent that angular ad ustment of the arms 15 with regard to the shaftsl and 17 is possible by proper manipulation of these parts and their set screws in such amanner as .to raise or lower the attachment. The journals of the shaft or support 1% may be secured against movement in the bearings 12, of the recording machine in any preferred way, if

this be desired as, for example, by means of nuts applied upon the ends of said shaft or support, and upon the spaced

side frames

18, 18 of the attachment I have provided adjusting screws 18 engageable with the spaced frame uprights 1, to position the attachment in a horizontal direction, it being apparent that by turning said screws they may be caused to project to a greater or less extent from the side frames 18 so as to position the operative parts of the improved perforating attachment farther from or nearer to the feed sprocket 2 of the recording machine, as may be desired.

The outer sides of the

side frames

18, 18 of the improved attachment are provided at their lower parts with integral laterally 'projecting offset lugs or

shoulders

19, 19 vertically alined and spaced apart from each other, cross bars or

tie members

20 and 21 being attached at their opposite 'ends thereto so as to extend transversely across the frame of the attachment at its lower part one above the other, the uppermost of said bars or members, as 21, being as herein shown formed in upper and lower sections for convenience in the production between them of a narrow elongated passage 13 adapted to be traversed by the record strip 190 as will be hereinafter explained.

At their upper ends the

side frames

18, 18 of the improved perforating attachment are provided with alined bearings 22 22 wherein are mounted adjustablepintles 23,

23 having tape-red orconica'l extremities :de- 7 tachably engageable in axially alined recesses 26 at .the opposite ends of a removable roll support whereon the unperfo rated paper roll 00 is removably supported, as clearly indicated in the drawings, so that the strip 00 maybe withdrawn from said roll support gradually during the operation of the improved perforating device.

For convenience and as herein shown, the roll support 25 is provided at onerend with a head or enlargement 32 affording an abutment against which one end of the paper roll 00 is adapted to bear when applied upon said support, the other reduced end of said support being provided in one side with a longitudinal channel 33 wherein is secured a spring retainer 33, the free extremity 34: of which is adjacent to the end of the roll support and is normally held by the tension of the spring material from which the retainer is produced, pressed outwardly from and beyond the side of said support, so that an inclined or beveled surface upon said extremity 3% is presented for contact with the paper roll when the same is being applied to V the support, in order that the roll may readily he slipped in place upon the support over said beveled'surface, while a shoulder upon-said extremity 34 of theretainer at its side opposite to said beveled or inclined surface operates by engagement with the paper roll when the latter is in place upon the support, to prevent withdrawal of the roll therefrom except the extremity of the retainer be first pressed down into the channel 33 as is permitted by its inherent elasticity.

One of the pintles 23 as herein shown is in the form of a screw longitudinally adjustable in the bearing 22 of the corresponding side frame of the attachment, so as to permit of being adjusted for positioning the roll support and unperforated paper roll carried thereby laterally of the attachment if this be desired, a lock nut being provided upon said screw for holding the same in adjusted position, and the other of said pintles 23 is formed as an'endwise movable bolt having atone side a slot or recess 26*.extencled lengthwise in it, engaged by a screw or'pin 27 upon the bearing 22 of the related side frame 18, said pin or screw 27 operating as a stop to limit the endwise movement of the bolt and to prevent with drawal of the same from the bearing. 29 represents a locking pin or detent pressed by a spring 30 endwise along an aperture in the bearing 22 and having :a pointed extremity 31 engageable with a conical recess in the side of the bolt or pintle 23 so as to hold the latter against endwise movement when in position toengage the roll support 25, as clearly shown in Fig. 10. By withdrawing the detent 29 against the tension of its spring, the bolt 23 may be'disengaged from the roll support to permit requires to be replaced.

As herein shown, the lugs 19, 19 project laterally from the side frames 18, 18 at that side o-fthe attachment which in operation is nearer to the feed sprocket 2 of the recording machine, while at the opposite or rear side .of the attachment said side frames 18,v 18 are provided with integral alined bearings wherein is supported for free rotation a guide roll 35 over which the unperforated paper strip 00 is adapted to be supplied, and in order to equalize the tension upon said strip during its withdrawal from the roll as and delivery to said guide roll 35 despite the intermittent operation of the feed sprocket 2 and the varying resistance offered by the paper roll on account of its gradually diminishing diameter, which is liable to tear the strip or its feed perforations,and to interfere with its gradual and regulated delivery from the roll 00- I provide an equilizing means interposed between said roll m and the guide roll 35 which as herein shown includes an equalizing roll 36 mounted to turn freely in the ends of arms 37 pivotally supported at 38' upon brackets 39 securedtothe lower part of the spaced uprights 1, of the recording machine below the improved perforating-attachment, or otherwise supported in such a manner that the strip fromthe paper roll m may be drawn downwardly beneath said equalizing roll 36 and thence be led upwardly to and over the guide roll 35 in such a manner as to form a loop as indicated at m in the drawings, the roll 36 being capable of a certain extent of vertical movement in such a manner as to tend to equalize the movement of, the strip as the same is withdrawn from the roll x and to compensate for the intermittent feeding impulses imparted thereto by the operation of the feed sprocket 2 while at the same time equalizing the strain and pull upon said strip as the same is drawn intermittently through the improved perforating attachment so as to avoid tearing of the feed perforations or breakage of the strip itself, as well as avoiding the unwinding from the roll 00 of an excessive length of the strip such as would be likely to occur were the sharp and sudden intermittent feeding impulses imparted directly to the roll 00 itself instead of'b'eingtaken up by the loop 92 The length-of the loop w and LOO the precise manner in -which the same is 7 formed are, of course, immaterial to my present invention. As herein shown, one or both of the arms 37 which afford'pi-votal supports for the equalizing roll 36 have.

extensions LO with which are coupled springs 41 the tension of which is exerted to hold the roll normally depressed with an elastic pressure nicely calculated to compensate for the intermittent feeding impulses {during which the strip is drawn through the attachment.

As herein shown, the guide roll 35 is provided adjacent to its opposite ends with circumferential flanges or

projections

42, 42 the inner surfaces of which are beveled or tapered in such a manner as to be adapted, by engagement with the opposite lateral edges of the strip a, to guide and center the same with relation to the feed sprockets of the recording machine and the perforating means of the improved attachment as will be hereinafter explained, and 52, 52 represent springs which bear upon the lateral or edge portions of said strip opposite to the guide roll 35 in such a manner as to retard the travel of the strip m through the attachment and to place a desirable tension upon the same between said guide roll 85 and the feed sprocket 21, in such a manner as to eliminate the likelihood of occurrence of any slack or looseness of said strip such as might result in improper positioning or spacing of the feed perforations produced in said strip by the perforating means which in the embodiment of the invention herein shown, operates upon the strip during'its travel from the guide roll 35 to said, feed sprocket 2. An idler roll is also positioned in the attachment adjacent to the guide roll 35 to assist in directing the strip therefrom to the perforating means which latter will presently be described. If'desired, this roll 70 may be replaced by a fixed rounded bar or equivalent member, or may be dispensed with altogether.

From the roll or member 7 0 the strip 00 passes through the aperture 43 hereinabove referred to between the upper and lower sections of, the' uppermost tie member 21, which aperture is made of dimensions sufficient to accommodate the free passage of said strip so that in its travel through the attachment the strip will be, held flush against the upper surface of the lower section of said tie member by reason of the tension exerted upon the strip by the operation of the leaf springs 52 hereinbefore referred to, and above said uppermost tie member 21 and also extended transversely of the attachment and of the strips traversing the same is positioned a vertically movable punch carrier or support 45, alined with and normally spaced apart from said tie member 21, its opposite end portions being provided with separately formed detachably mounted

punches

44, 44 the lower ends of which are pendent parallel with each other beneath said carrier 45 and are adapted to traveise vertical bores or passages 46 provided in alinement with each other through the spaced upper and lower sections of saidtie member 21 when said carrier or support is depressed, in such a manner as to penetrate the strip as within the aperture 43 and adj acent to its opposite lateral edges for the production of the feed perforations therein.

The proportions and arrangement of the parts, as herein shown, are such that when in their normal inactive or elevated positions, the lower ends of'the punches 44, 44, are engaged within the

bores

46, 46 of the upper section of the tie member 21, and stand above and out of position for contact with the surface of the paper strip m traversing the aperture 43, said upper section of the tie bar 21 actingas a stripper to compel disengagement of the punches from said strip when the punches are retracted upwardly, so that said punches offer no interference to the feeding movement of said strip during the intervals intervening between successive depressions of said punches, the alinement of the bores 46 of the lower section of the member 21 with said punches assuring penetration of the strip lying flush upon said lower section when said punches are depressed, for the production of the feed perforations in said strip and being traversed by the particles of paper removed from said strip by said punches in theproduction of said perforations, which particles are thus discharged at the underside of the tie member 21.

54 represents a receptacle or drawer removably; positioned between the tie-

vmembers

20 and 21, open at its top to receive the particles punched from the strip and discharged at the underside of the upper member 21, said drawer being provided at its lower part with a spring retainer 55 having a shouldered extremity 56 engaged beneath the lower tie bar 20 in such a manner as to lock the receptacle or drawer securely thereto when inserted between the members 20 and21. Upon depressing the shouldered end of the retainer 55 to disengage it from beneath the member 20, the drawer orwreceptacle may be removed" from the attachment to permit of bein emptied whenever necessary. A handle 5% is provided upon the rear side of said drawer to facilitate its removal. I

' 47, 47 represent parallel guides connected with the opposite ends of the punch support or carrier and pendent beneath the same, their lower parts traversing alined apertures in the

lugsorprojections

19, 19 ofthe respective side frames of theimproved' attachment, so as to be adapted for endwise movement therethrough, and being connected below the lowermost tie member 20 with the opposite ends of a cross head 48 which is adapted for operation from or in time with the operation of the actuating ,means for the recording punches 4 of the monotype recording machine, by means which will be presently described, in such a manner as to depress the punch support or carrier 45 in order that its

punches

44, 44 may penetrate the strip a; for the production of feed perforations therein at or for each individual actuation of the recording means, and 49,

strip; at and housed within the bores 46 of the upper section of said member 21 to permit free feeding movement of said strip after each punching operation. As herein shown each of said springs has its upper end coupled with the lower end of a screw .50 which is passed through an aperture in the end of the tie member 21 and is engaged with a wing nut 51 above said tie member by turning which wing nuts the screws may be moved vertically to adjust or regulate the-tension of said springs individually or jointly. r i

V 58 represents an auxiliary retracting spring secured at its central part to the underside of the punch support or carrier 45, and having its arms bent downwardly in position to engage the uppermost tie member 21 when the punches are depressed for the production of the feed perforations in the strip, whereby t'he upw ard' retraction of said punches and their disengagement from the strip is assured. prior to the feeding move- 1 ment 'ofthe latter; 62, 62 represent adjustable stops, herein shown in the form of screws mounted adjacent to the opposite ends of the punch carrier or support 45, with their tipsprojecting beneath the same and adapted for engagement with the upper tie member 21 of the attachment frame in such a way as to limit the descent of said punches when the cross head 48 is actuated, and 63, 63 represent similar adjustable stops also in the form of screws carried adj ac'ent to opposite ends of said cross head and having their tips projecting above the same in position for engagement against the underside of the lower tie member 20 of the attachment frame in such a way as to limit the upward retracting movement of the parts and prevent the punches from being withdrawn completely from: the bores 46 of the upper section of the upper tie member 21 upon upward movement of the punch support or carrier. By adjustment of these

screws

62 and 63 the vertical movements of the punches may be regulated at will.

As herein shown, the

respective punches

44, 44 and their bores or

passages

46, 46 in the tie member 21 are distinctively formed or shaped, so as to be adapted for the production of distinctively different series of feed perforations along the opposite sides of the record strip w, and for convenience in replacing or substituting said punches, I have herein shown them detaohably secured to the carrier or support 45, for whiohlpurengage the head 59 ofthe punch so as to hold the latter securely in place.

The means for operating the cross head 48 in time or synchronism with the keys 6 of the recording machine key board and their related record-making punches 4, may obviously be of any preferred kind, but as herein, shown this means includes an adjustable connection pendent" below the central part of the cross head and adapted for connection at its lower end with 71 projecting rearwardly from the rock shaft 5, so that at each rocking movement imparted to said shatt upon the operation of one of the keys 6, the cross head is drawn downwardly and

the'punches

44, 44 are caused to penetrate the paper strip a for'tlie production of the feed perforations therein. As hereinshown, the actuating connection employed includes upper and lower members-or stems 72, 72, alined with each other, one of said stems or members being apertured'at its upper end for the passage of a removable pin or bolt 74, which traverses spaced apertured lugs centrally produced upon the underside of the cross head so as toafl'ond detachable connection therewith, while the lower of said stems or members .72 is provided with a head or the like engaged beneath the arm 71 of the 7 rock shaft 5 so that when said arm is depressed upon the rocking shaft ensulng upon depression of either of the keys 6 at the key board, the cross head '48 is also drawn downwandly, together with the punch carrier or support 45, to cause the

punches

44, 44 thereof to penetrate the record strip for the production .of the feed perforations therein. The actuating connection also includes a central member 73 with which each of said stems or

members

72, 72 has jointed or universal connection, nuts being provided upon said members or stems 72, 72 engageable above and below the central member 7 3 by which means the connection may be adjusted lengthwise to [assure proper operation of the improved perforating attachment.

By this construction and arrangement of the parts it will be apparent that whenever a key 6 at the key board of the recording machine is depressed, the mechanical or other suitable connection of the punch actuating cross head 48 of the improved attachment with the recording mechanism will assure the operation of the

punches

44, 44, to produce feed perforations in the record strip w immediately in advance of the feed sprocket 2, and said punches being 'alined with the teeth of said sprocket and the strip held with a uniform tension during the production of said feed perforations, it will be apparent that absolute registry of the feed perforaions with the sprocket teeth will be assured and the possibility of loss .of such registry due to expansion or contraction of'the strip will be entirely done away with, while at the same time a material economy is attained by reason of the avoidance of any separate operations such as have heretofore been necessary for the preliminary perforation of the record strip.

After the depression of each key 6 at the key board of the recording machine, the feed sprocket 2 being actuated in the ordinary manner, serves to feed or draw the rec- 0rd strip not only past the record forming punches 4, but also to draw or feed said strip to exactly the necessary extent past the

punches

44, 44 ment, so that the spacing of the feed perforations produced upon successive operations of the

punches

44, 44 will conform accurately to the toothing of the feed sprocket in order that the likelihood of subsequent tearing of the feed perforations may be avoided, while at the same time the employment of the equalizing means including the looping roll 36 between the paper roll 00 and the guide roll 35 avoids excessive unwinding or jerking of the strip from the paper roll incident to the intermittent character of the feed, as well as such pull or draft upon the strip as might interfere with uniform operation of the tensioning means 52 or result in tearing of the feed perforations.

The employment of the equalizing means including said looping roll 36 also permits of using in the recording machine a paper roll of considerably greater diameter than is possible of employment where such equalizing means are omitted, it being apparent that where the stripis unwound from said roll in a graduated and regular or comparatively continuous manner, irrespective of the intermittent character of the feed, the roll may be of much greater size than is possible of employment where, as heretofore, the feeding impulses are imposed directly upon of the perforating attachthe roll to unwind the same intermittently. It will thus be apparent that the equalizing means is possessed of advantages and'functions which may in some cases render the same desirable for employment independently of the improved perforating means, and for this reason I do not desire to be understood as limiting myself to the use of said equalizing means exclusively in connection with the perforating means herein shown. i i

In order to. deliver the perforated strip accurately to the feed sprocket 2 of the recording machine from the perforating means includingthepunches 44, 44, I- have herein shown the improved attachment provided' with a delivery roll or member herein shown provided With spaced plural rubber or other surfaced

enlargements

64, 64, over which the perforated strip 00 is adapted to pass to the feed sprocket 2, said enlargements being alined and adapted for contact with or pressure upon the toothed parts of the .sprocket wheel so as to assure the delivery of the newly perforated strip or web thereto. The rubber surfaced

enlargements

64, 64 are spaced to engage the strip 00 in line with the feed perforations thereof and their yielding surfaces permit the penetration of the. teeth of the feed sprocket slightly thereinto to assure registry of said teeth with the ,feed'perforations of said strip.

As herein shown the delivery member has reduced portions affording journals which are mounted to turn freely in

open bearings

66, 66 upon the bent forward ends of

carriers

67, 67, mounted upon the respective spaced side frames 18, 18 of the attachment, and capable of adjustment lengthwise or to ward and from the feed sprocket to permit of positioning the-delivery roll or member at a greater or less distance beyond the frame of the attachment and thus assure proper delivery of the newly perforated strip to said sprocket. The side frames 18, 18 are herein shown provided with

slots

68, 68 traversed by bolts or screws 69 on the carriers 67 67, which screws or bolts may be loosened to permit endwise adjustment of the carriers or tightened to hold them in adjusted position. The adjustability of the delivery roll, and the various adjustments hereinbefore referred to whereby the attachment frame may be desirably positioned upon the frame of the recording machine are features of material importance in the em-' tion it will be apparent that the improved perforating device constructed according to my invention is of an extremely simple and comparatively inexpensive nature, and is particularly Well adapted for use by reason not only of the economy attained by dispensing with the employment of previously perforated paper rolls for the production of records, but also by reason of the accuracy with which the perforations are produced in the record strip without liability of loss of registry through expansion or contraction of the paper, and the avoidance of liability of tearing or otherwise impairing the feed perforations or breaking the strip due to the employment of the improved equalizing and tensioning means, and it will also be obvious from the above description of myinvention that the device is susceptible of considerable modification without material departure from the principles and spirit of the invention, as defined in the appended claims, and

for this reason I do not desire to be understood as limiting myself to the precise formation and arrangement of the several parts of the device as herein set forth in carrying out my invention in practice.
