Specification of Letters Patent.

Patented Jan. 27 1 914.

T 0 all whom it may concern:

Be itknown that we, LOUIS G. J ULIHN and JOSEPH FRANK CULVERWELL, both citizens of the United States of America, residing at \Vashington, in the District of Columbia, have invented certain new and useful Improvements in Copy-Holders, of which the following is a specification.

This invention relates to improvements in copy holders for typewriting machines and is directed more particularly to the equipment of what is known as a fiat platen or downwardly printing typewriter with copy holding means adapted to be automatically operated to line space the copy as the typewriter is manipulated to line space the writing on the work sheet.

The primary object of the invention 15 to provide a machine of the character specified with a copy holder including a copy holding drum or cylinder operated automatically, incident to the normal operation of the typewriter, by simple and efficient mechanism mounted exclusively upon the traveling machine structure and requiring no attachment to the fixed substructure, in order that the copy holding and manipulating mechanism will require no attention when the machine is placed upon or removed from the stationary platen.

Another object is to equip the operating mechanism of the copy holder with variable means whereby the feed of the copy may be regulated relative to the line space movement of the typewriter in order to facilitate the handling of copy the lines of which are spaced wider or narrower than the desired spacing of the record to be typewritten from the copy.

A' further object is to provide the copy holder operating mechanism with setting means whereby the copy, according to the wishes of the operator, will be moved both back and forth as the machine is moved back and forth over the platen, or in a forward direction only, remaining stationary when the machine is moved back, or held stationary during the movement of the machine in both directions.

A still further object is to combine with the copy holder and its automatic operating means an instrumentality whereby the copy holder may be rotated freely in either di- 'a modified form of copy holder.

rection by hand to facilitate the displacement, replacement, or adjustment of the copy. I

Each part is indicated by its appropriate reference character wherever shown.

It may be stated by way of premise that the machine to which the copy holder is shown attached is what is known as the Elliott-Fisher billing machine of commerce. This machine is what is known as a flat platen or downwardly printing typewriter in which a stationary fiat platen 1 supports a machine frame 2 movable longitudinally of the platen to line space the writing effected by printing mechanism, not shown, movable with a carriage 3 mounted to travel transversely of the platen on the frame 2 to letter space the writing. The carriage 3 is fed to the right (viewed from the front) by carriage propelling mechanism in the form of spring drums 4 connected to the carriage by tapes 5. The movement of the carriage is controlled by an escapement, not shown, operated by the keys of the printing mechanism in a. manner well understood in the art. For a more complete disclosure of the typewriter structure than is thought necessary for present purposes reference is made to Patent No. 573,868 to R. J. Fisher.

(In accordance with this invention it is designed to support the copy above the rear of the machine. Therefore brackets 6 are secured to the rear of the frame 2, as shown in Fig. 1, and support standards 7 which rise to a point above the carriage 3 and are provided at their upper ends with bearings 8 for a horizontal drum shaft 9 upon which is mounted intermediate of the bearings 8 a cylindrical copy holding member-10 which may be and preferably is in the form of a hollow drum provided with hubs 11.

The drum 10 is designed to rotate with the shaft 9 to which it is secured by a key 12 fixed within one of the hubs 11 and extended into an elongated key way 13 in the shaft 9. This character of connection between the shaft and drum compels their rotation in unison, but permits the shaft to have slight independent longitudinal movement for the purpose of disconnecting the drum from its operating mechanism in a manner and for a purpose to be described.

To one end of the shaft 9 is secured a thumb wheel 14: by which the copy holding drum 10 may be manually rotated and at the opposite end of said shaft is supported a friction disk 15 rotatable with the shaft 9 through the interposition of a spline 16 and urged laterally by a spring 17 against a gearing screw 18 screwed into the end of the shaft 9 and serving to limit the movement of the disk under the impulse of the spring. The spring 17 encircles the shaft 9 and is backed by an anti-friction collar 19 between which and the adjacent bearing 8 are interposed a series of anti-friction balls 20. It will thus be seen that the friction disk 15 is mounted to yield slightly longitudinally of the shaft 9 against the resistance of the spring 17, but is compelled to rotate with said shaft, the friction incident to such rotation being reduced by the interposition of an anti-friction bearing bet-ween the shaft bearing 8 and the backing collar 19.

Disposed in frictional engagement with the outer side face of the friction disk 15 is a second friction disk 21 mounted to rotate with but slidable vertically upon the squared upper end 22 of a vertically disposed shaft 23 journaled in bearings 24 formed at the outer ends of arms 25 extended laterally from the upper and lower ends of one of the standards 7, this particular standard being extended considerably below the bracket 6 to locate the lower arm 25 adjacent to the plane of the platen 1.

The disk 21 is provided with a threaded hub 27 designed to be engaged by a feed regulating nut 28 fixed to rotate upon the upper end of the shaft 23 and internally threaded to engage the threaded hub 27. By rotating the regulating nut 28 the disk 21 may be elevated or depressed and thus adjusted toward and from the center of'the disk 15 to regulate the feed of the copy, or in other words, to vary the degree of movement transmitted to the copy holder drum 10 from the shaft 23.

At the lower extremity of the shaft 23 is secured a beveled gear 30 meshing with a similar gear 31 having an enlarged hub 32 mounted on the short horizontal shaft 33. The shaft 33 is journaled in a bearing 3& at the lower extremity of the standard 7 and at the side of the bearing opposite the gear 31 said shaft is equipped with a spur-gear 35 meshing with one of the toothed tracks or guides 36 which are ordinarily disposed longitudinally of the platen and sup-port the frame 2.

It will now be seen that if the machine frame 2 is advanced over the platen the pinion 35 will be rotated, thus rotating the shaft 33, and if the pinion 31 is secured to the shaft 33, motion will be transmitted through'the gears 31 and 30 to the shaft 23 and thence through the friction disks 21 and 15 to the shaft 9 and drum 10 of the copy holder, it being noted that the disk 15 is held in frictional engagement with the disk. 21 by the spring 17. Therefore the forward movement of the machine frame 2 to line space the record will be accompanied by rotary movement of the drum 10 to line space the copy sheet held thereby and the relative extent of these movements of the two recited members will depend upon the arrangement of the intermediate gearing.

As we have already seen, the friction gearing located in the line of the operating connections of the drum may be adjusted to regulate the relative movement of the drum and machine frame according to the spacing of the copy. In addition to this regulation of the feed, other regulations of the copy holder mechanism are desirable. Forinstance, in some classes of work it is desirable to have the copy moved forward and back as the writing mechanism is moved forward and back over the platen, since this will maintain a correspondence between the writing line of the machine and the reading line of the copy in all positions of the former. For instance, the operator may write a numberof lines on the work sheet with the feed of the copy keeping pace with the progress of thewritten record and if then the machine is thrown back to any given previous lineof writing, the copy is automatically fed back to the same line to facilitate comparison.

In other classes of work it is desirable to have the copy fed forward as the writing mechanism moves forward over the platen, but remain stationary when the writing mechanism is moved back. This is particularly desirable where the character of the copy is such that a number of record sheets will be required, or in other words, where machine advances in making the record and to then remain stationary so that the copy will be in position for a continuance of the work when the machine is moved back to the rear end of the platen to begin the writing of a new record sheet. Again, when it is not desired to use the copy holder, it is preferable to disconnect the mechanism so that the fewest possible number of parts will be operated by the machine and burden its advance. To provide for these three conditions, to-wit automatic feed of the copy in both directions with the'm'achine, automatic feed of the copy in one direction only with the machine, or no automatic feed of the copy, what may be termed Setting means for the copy feeding mechanism is provided.

The hub 32 of the gear 31, is counterbored, as indicated at 36, for a-distance of approximately one-third of its depth for the reception of the end of a hollow hub extension 37 and beyond this counterbore the hub is provided with internal longitudinally disposed ratchet teeth 38. The short-shaft 33 is extended through the hub 32 and into the extension 37 and is provided with a longitudinal slot or recess 39 extended from the left hand end of the shaft in Fig. 7, the inner or bottom wall of the recess at its opposite end being curved to form a cam face 40. Within the slot or recess 39 is disposed to slide longitudinally the flattened end 41 of a sectional setting shaft 42 the sections of which are joined by a coupling 43 which compels them to move longitudinally in unison, but permits the inner section to rotate independently of the outer section. At the inner end ofthe flattened portion 41 of the setting shaft is pivotally mounted a dog or clutch member 44 yieldingly urged by a spring 45 into engagement with the internal teeth 38 of the hub 32.

The dog 44 is provided with an inclined side face, as shown in Fig. 8, so that the teeth 38 and the dog 44 constitute a awl and ratchet connection between the sha 33 and the gear 31, provided the dog is free to swing back when urged against the inclined faces of the teeth 38. By reference to Fig. 9, however, it will be seen that when the setting shaft is moved to the limit of its inward movement, the free end of the dog will ride up the inclined face 40 and wil be effectually blocked thereby against such backward movement as would serve to disengage it from the teeth 38. It will therefore appear that in one position of the setting shaft, to-wit the first position or that shown in Fig. 9, the dog'48 will establish a ratchet clutch connection between the gear 31 and the shaft 33. Consequently, when the machine frame is moved either forward or back, the rotation of the pinion 35 in opposite directions will transmit rotary motion in opposite directions to the copy hold ing drum 10. If, however, the setting shaft 45 is withdrawn to the second position or sufliciently to remove the free end of the dog 44 from a position opposite the cam face 40, said dog will coact with the teeth 38, as shown in Fig. 10 to transmit motion from the shaft 33 to the gear 31 during the forward movement of the machine, but will click idly over the teeth when the shaft 33 rotates in the opposite direction during the backward movement of the machine. The third condition is effected by a still further adjustment of the setting mechanism. It has been seen that in one endwise position of the setting shaft 42, the dog 44 establishes a positive clutch connection between the shaft 33 and the. gear 31; that in another position of the setting shaft the 'dog 44 establishes a ratchet connection between said shaft and gear, and it will now be seen that by further withdrawin the setting shaft 42 to the third position shown in Fig. 11, the dog 44 will be withdrawn entirely from the teeth 38 by the engagement of said dog with the inner end of the hub extension 39, thus disconnecting the shaft 33 and the gear 31 and causing the entire copy holding mechanism, with the exception of the pinion 35, the shaft 33 and the inner section of the setting shaft 42, to remain stationary as the machine is advanced over the platen in either direction.

in addition to the elements described, the setting mechanism includes mechanism by means of which the operator may conveniently shift the setting shaft 42 to secure any one of three conditions specified. EX- tended horizontally from front to rear of the machine frame 2 adjacent to the bottom thereof is a shaft 46 journaled in suitable bearings 47 carried by the machine frame and provided at its front end with a thumb wheel or other operating device 48 and at its rear end with an arm 49 having a slot and pin connection 50 with the outer end of the setting shaft 42. By rotating the thumb wheel 43 the shaft 42 may be shifted to either of its-three set positions.

In order that the operator may be apprised of the exact condition of the setting mechanism, it is preferable to provide an indicator in the form ofa pointer 51 fixed to the frame of the machine and coacting with numbers or other suitable indications 52 on the face of the thumb wheel 48. When the pointer is opposite 1 the setting mechanism is in the first or completely clutched position; when the pointer is opposite 2 the setting mechanism is in the second or ratchet position, and when opposite 3 the mechanism is disconnected.

It has been stated that the shaft 9 is permitted limited endwise movement independentof the drum 10 for the purpose of shifting the friction disk 15 against the resistance of the spring 17. This movement of the disk is intended to withdraw the latter from contact with the coacting friction disk 21 so that the drum may be freely rotated by hand in either direction when desired. This endwise movement of the shaft 9 is effected by pulling outward upon the end wheel 14 which may then be turned to rotate the platen, the endwise shifted position of the shaft and disk being maintained by a swinging stop 53 mounted on one of the bearings 8 and arranged to be swung down by a spring. 54 into engagement with the side face of the hub 55 of the wheel 14, see Fig. 3. Normally the stop 53 rests upon the periphery of the hub 55, as shown in Fig. 1, but when the shaft 9 is moved endwise to disconnect the drum from its operating mechanism, the stop automatically moves into position to prevent the return of the parts to normal position when the wheel 14 is released. The stop 53 is provided with a finger piece 56 by which it may be readily withdrawn from its active position when it noeener is desired to permit the spring 17 to restore the operative relation between the friction disks 15 and 21.

the bearings 8 for the drum shaft may be integral with the standards 7, but for convenience of manufacture and assembling these hearings are preferably formed at the upper ends of bearing brackets 8 constituting extensions of the standards 7 and secured thereto by stud screws 8*, the arm 25 which sustains the upper bearing 24 of the shaft 23 being formed as an integral part of one of these brackets. Similarly the lower bearing 24 for the shaft 23, as well as the bearing 34 for the shaft 33, are formed as integral portions of a bearing bracket 7 secured to the lower end of one of the standards 7 by a set screw 7 The retention of the copy sheet 00 on the copy holding drum 10 may be efiected by any of the various paper holding instrumentalities in common use in copy holding and analogous devices, but by preference a pressure frame 57 is mounted to swing from the brackets 8 and is equipped with a series of pressure rolls 58 urged against the periphery of the drum by springs 59. The side arms 60 of the frame 57 are curved, as shown in Fig. 5, and constitute supports for a transversely curved sheet metal apron 61 which assists in guiding the copy sheet a: around the under side of the drum 10 and between said drum and the pressure rolls 8. in order to cause that portion of the sheet :1 extending above the rolls 8 to lie smooth upon the drum, a guide in the form of a bail 62 is secured to the bearings 8 and is extended over the drum and closely adjacent thereto, as shown in Figs. 1 and 5.

Briefly the operation of the mechanism illustrated in the first fourteen figures of the drawings is as follows: The operator first moves the hand wheel 14 laterally thus withdrawing the friction disk 15 from the disk 21 and disconnecting the copy holding drum 10 from its operating mechanism. The parts are retained in this position by the stop 53 which automatically drops into place, as

shown in Fig. 3, and permits the drum to be freely rotated in either direction by manipulation of the wheel 14. The bottom edge of the copy sheet m is then passed under the guide 62 and around the front of the-drum and bet-ween the drum and the pressure roll 58, the lower edge of the sheet being caught and guided by the apron 61. When the copy sheet has been thus positioned on the copy holder, the stop 53 is moved from the position shown in Fig. 3 to that shown in Fig. 1, and the shaft 9 is thus permitted to move endwise to bring the disk 15 into engagement with the disk 21 and thus reestablish an operative connection between the drum and its automatic operating mechanism.

The operator now transcribes a line on the work sheet supported by the platen 1 after which the machine is advanced to the next line position in a manner well understood in the art. As the machine advances the pinion 35 engaging the stationary rack 36 rotates and this movement is transmitted to the drum through the intermediate gearing for the purpose of feeding the copy sheet a down until the next line of the copy drops to the reading position immediately above the pressure rolls 58. If the transmitted motion feeds the copy sheet a distance greater or less than one line space, the feed is regulated by rotating the nut or cap 28 for the purpose of moving the disk 21 the proper distance relative to the axis of the disk 15 to secure the proper feed of the copy. The operator now proceeds as before, manipulating the machine in the usual manner and automatically effecting the line spacing of the copy as the machine advances to line space the record on the work sheet. If the setting means of the copy feeding mechanism is in the first position, to-wit that shown in Fig. 9, the copy will be fed forward and back as the machine is moved forward and back over the platen so that should the operator move the machine back to any line previously written, such movement of the machine will cause the copy sheet to be fed back to the corresponding line to facilitate comparison. If, however, the capacity of the copy sheet is greater than that of a single work sheet, the setting mechanism may be adjusted to the second or ratchet position, indicated in Fig. 10. If now, the machine is moved forward the copy will be correspondingly advanced, but when the capacity of the work sheet is reached and the machine is moved back to the rear end of the platen for the purpose of beginning a new sheet, the copy will remain stationary until the machine is again moved forward, the feed of the copy thus keeping pace with the feed of the record and being unaffected by the rearward movement of the machine over the platen. If now, it is desired to discontinue the use of the copy holder or of the automatic copy feeding mechanism thereof, the setting means is moved to the third position, shown in Fig. 12, thus entirely disconnecting the main driving shaft 33 from the gear 31. With the setting mechanism in this position the movement of the machine will merely cause the rotation of the wheel 35 and the shaft 33, but will be unburdened by the movement of any of the other elements of the copy feeding mechanism. A pointer or indicator w is preferably attached to the rear of the carriage and its upper end traverses the reading line of the copy as the printing point of the machine traverses the writing line of the record,

extended through and journaled in oneof the bearings and provided with a thumb wheel 14 by which the drum may be moved longitudinally against the resistance of a spring 66 to disengage the clutch members 63 and 64:. \Vhen the drum is thus disconnect-ed from the shaft 9 it may be freely rotated by the manipulation of the wheel 14. The drum 10, however, is normally held in clutched position by the spring 66 encircling the hub 65 and interposed between the end of the drum 10 and the adjacent bearing. For the purpose of retaining the drum disconnected a stop 53, similar to the stop 53 of the first described construction, is mounted to coact with the end wheel 14:. At the end of the shaft 9 opposite the wheel 14 is secured a sprocket wheel 67 geared through the medium of a sprocket band 68 with a similar sprocket wheel 69 fixed to one end of a short shaft 70 which carries at its opposite end a friction wheel 71 having a rubber or other frictional surface 72 arranged in frictional contact with the adjacent track 36 at the side edge of the platen. The shaft 7 0 is ournaled in an adjustable bearing 73 having a vertically disposed sleeve 74 adapted to receive and slide u on the lower end of one of the standards Connected at one end to the sleeve 74 and at its opposite end to the standard 7 is a spring 7 5 which when unrestrained elevates the bearing 73 for thepurpose of withdrawing the wheel 71 from engagement with the track 36. Coacting with the upper end of the sleeve 74 is a cam 7 6 pivoted on a stud 7 7 projecting from the standard 7". The cam 76 is designed to be swung by a controlling lever 7 8 fulcrumed adjacent to the upper end of the standard 7" and connected to the cam 76 by a link or connecting rod 79. To prevent the sleeve 74 from turning on the standard suitable guiding means may be provided, as for instance a projection 80 entering a longitudinal slot 81 in the standard 7" and projecting from a screw 82 screwed into the wall of the sleeve, see Fig. 18.

Briefly the operation of the last described form of mechanism is as follows: By moving the hand wheel 14 laterally, the drum 10 is drawn endwise to separate the clutch members 63 and 64 thus disconnecting the drum from the shaft 9 and permitting the stop 53' to drop to its active position'to hold the drum disconnected while the latter is freely rotated by hand to facilitate the placing of a copy sheet thereon. When the sheet is in proper position the stop 53 is withdrawn to the position shown in Fig.

10, thus permitting the spring 66 to effect the rengagement of the clutch members 63 and 64. When the machine is line spaced over the platen after the writing of a line the rotation of the wheel 71 incident to its frictional engagement with the track 36 will effect the rotation of the drum to line space the copy sheet through the medium of the gears 67 and 69, the sprocket band 68 and the shafts 70 and 9*. If the operator desires to discontinue the automatic feed of the copy, he merely elevates the outer end of the lever 78 which will swing the cam 76 the face of which recedes toward the axis of the cam thus allowing the spring 75 to elevate the bearing 73 and withdraw the friction wheel 71 from engagement with the track 36 Similarly, if with the parts thus disconnected, it is desired to effect the automatic feed of the copy, it is simply necessary to throwdown the lever 78 thus swinging the cam 76 back to normal position and causing said cam to depress the bearing 73 for the purpose of moving the wheel 71 into contact with the track 36*. The devices for retaining the copy sheet on the drum are substantially the same in this form ofthe invention as in the form first described and therefore appear to require no specific description.

The term copy feeding mechanism is intended to embrace, in the several forms of the invention, those elements which are set in motion by relative movement of the platen and printing mechanism to transmit movement to the copy holder.

It is thought that from the foregoing, the construction and operation of the copy holding and feeding mechanism will be clearly comprehended, but while the present embodiments of the invention appear at this time to be preferable, we expressly reserve the right to effect such variations of the illustrated structure as may come fairly within the scope of the protection prayed.
