TYPE-WRITING MACHINE.

Specification of Letters Patent.

Application filed June 29, 1906. Serial No. 324,032.

have invented certain new and useful Im-' provements in Type-VVriting Machines, of which the folloi'ving is a specification.

My invention relates to typewriting machines and more particularly to mechanism for effecting a feed ofstencil plates, cards or like work sheets.

One object of my invention is to provide ellicient mechanism'for quickly and accurately feeding stencil plates, cards or the like to operative position in the machine.

Another object of my invention is to provide means for regulating'the feed to suit different characters of work or work sheets employed.

A still further object of my invention is to provide efficient means for automatically discharging the plates, work sheets or cards from the machine after they have been written or perforated.

To the above and other ends which will hereinafter appear my invention consists in the features of construction, arrangements of parts and combinations of devices to be hereinafter. described and plaime In the accompanying drawings, wherein like reference characters indicate corresponding parts in the various views, Figure l is a side elevation with parts broken away i 5 of. one form of machine embodying my in- 'vention..

Fig. 11 is a detail perspective view of one of the followers or discharging devices which feed the stencil plates from the hopper.

The machine to which I have shown my invention applied in the present instance is a stencil making machine which employs a plurality of stencil cutting type bars or bars provided with points or needles arranged on each bar in accordance with the character of perforations to be formed in the stencil plate by the individual type bar and the feed mechanism is intended to feed the stencil plates successively to the printin or stencil cutting position, to properly feed the plates from line to line after they have arrived in such position and to feed each stencil plate out of the machine after it has been completed. It should be understood, however, that my improved feed mechanism may be employed in. connection with ordinary cards, envelops or the like in various forms of typewriting machines and for convenience I will refer herein to the stencil plates as cards or Work sheets, though it should be understood that these terms are intended to apply generally to different characters of work sheets, whether they be ordinary cards, envelops, stencil plates. or other forms of work sheets, and whet-her they are to be printed upon in the usual manner or perforated to make stencil plates as in the present construction.

The machine shownin the drawings has a main frame, key levers, type bars and escapement resembling the corresponding parts of the Remington typewriter; indeed, these parts of a typewriting machine may be used without change in carrying out my invention.

The frame of the machine comprises a base 1, corner posts 2 and a top plate 3. Key levers 4, provided with the usual finger keys 5, are fulcrumed on a fulcrum bar'6 secured to the base of;the machine. Each key leveris pivotally connected at 7 to a link 8, the upper end of which is pivoted at 9 to a type ar 10 pivoted at 11 to] type type bar carries 1- iora tin' needles'oi mts 13 arranged o tlief'character f: the individual bar which carriedtliem.

Each key when pressed is operative to swing the associated so-called type bar 10 to the printing or perforating position so that the points 13 will impact against the stencil plate or work sheet and the platen by which it is fed, as will hereinafter more clearly appear. Extending beneath the key levers 4 is a uni versal bar 14 connected at its ends to upwardly extending links 15 which in turn are connected to the ends of a transverse bar 16 carried by the forwardly extending arm 17 of a dog rocker pivoted at 18 to a depending bracket 19 which is secured to the top plate. The upwardly extending arm 20 of the dog rocker carries the usual feed dogs 21 which cal er-ate with a feed rack 22 carried by rearwardly extending arms 23 connected with a carriage 24. Said carriage comprises a substantially rectangular frame having front, rear and. side bars, as shown in Fig. 2. A restoring spring 25 is connected at one end to the dog rocker and at its opposite end to the depending bracket 19 to restore the dog rocker and the universal bar to the normal position when pressure is released on the finger key 5.

A spring drum 26 has one end of a band 27 connected thereto, the other end of said band. being connected to a bracket arm 28 secured to the carriage. A supporting and guide rod 29 is mounted in u wardly extending lugs 30 which project mm the top plate and this rod passes loosely through ears 29% (Fig. 1) projecting from the carriage. Said ears prevent accidental displacement of the carriage, but the weight of the latter at the rear is carried by grooved rollers 31 mounted on the carriage and 00- operating with the guide rod 29. The forward side of the carriage has aroller 32 journaled in 1: depending block 33, the roller bearing on a fixed track 34, thus sup orting the forward side of the carriage. e forward side of the carriage may be raised to inspect the work or for any other pur- 1059, the connection with the rod 29 servmg as a pivot.

The carriage is adapted to move from side to side of the machine, the extent of such movement depending on the length of the work sheets or stencil plates employed. A depression of a finger key will effect a stepby-step letter space feed movement of the carriage in the manner usual in typewriting machines. A cylindrical, rotary platen 35 is mounted upon a shaft 36 supported in bearing plates 37 and 38 which project up-' wardiy from the side bars of the carriage 24 and the outer ends of said shaft are provided with finger wheels 39 and 40 by which the platen may be turned. A longitudinally extending groove or slot 41 is formed within the platen throughout the length thereof. A textile covering of two or more layers 42, 43 surrounds the platen and the ends 44, 45

are adapted to be received within the longitudinal groove or slot 41 in the platen as shown in Fig, 3. A clamping piece or stri 46 is adapted to be received between the ad jacent ends 44, 45 of the-textile covering,

as shown in Figs. 3 and to clamp or socure the covering in place on the platen. Outwardly projecting fingers47 are provided on the locking strip in order to remove it to afford a removal of the textile platen-covering. The textile coverings of e8 to the platen permit the perforating need pass through the stencil sheet. As will appear more clearly hereinafter, the art of the laten having the slot 41 therein 15 never at the bottom next to the work sheet at the time when the perforating of saidsheet is taking place.

A serrated or toothed feed wheel 48 is formed on the platen head at each end of the platen in order to engage the stencil plates and feed them forward as the platen rotated, as will hereinafter more clearly ap pear. A supporting plate 49 (shown in detail in Fig. 5) has upwardly projecting ears 50 perforated at 51 to receive heade screws 52 by which the rear portion of the supporting plate is secured to the rear cross-- bar of the carriage. Outwardly extending portions 53 on the sup orting late 49 rest upon inwardly extending brac et arms 54 which are formed integral with the plates 37 and 38. Screws 55 are received in perforations in thebrackets 54 and take mtO threaded openings 56 in the projections 53 to'secure the forward portion of the supporting plate to the carriage. A trough or chute 57 has rearwardl extending ears 58 by which it is secured by screws 59 to the forward edge of the supporting plate 49. The forward portion of the chute is provided with an upwardly extendin portion 57 formed with forwardl exten ing lugs 60 which project over an are adapted to bear upon the front rail or crossbar 61 of the carriage. The construction of the chute 57 is such that it extends longitudinally of the platen and is adapted to receive the work sheets or stencil plates as they are fed forward from the platen. A stencil-plate or worksheet holder or hopper 62 which is adapted to'reccive and maintain the work sheets in a flat state is vertically disposed in the rear of the platen and the rear wall of the hopper secured to a depending flange 63 on the supporting plate by screws 64, whereas each side wall of the hopper is provided with a downwardly and outwardly extending ear (3?; which is formedi tegral therewith and extends down throng a slit (35 in the supporting plate 49 and is secured to the bottom thereof by screws 66.

The upper edges of the hopper are bent outwardly, as indicated at 67 to provide a flaring mouth for the hopper to readily reoeive and guide the stencil plates or work sheets into the hopper. ,The hopper is closed on three sides and is open or cut away at just short'of the bottom thereof; terminat ing justabove the supporting plate 49 so as to provide a horizontal slit or opening 7 (Fig. 3), through which the stencil plates may be discharged one at a time. The

central portion of the supporting plate 49 is cut away to form an opening 71 Fig. 5) over which the hopper is mounted. Betfi een the opening 71 and the slits 65, there arefing'ers 73 (Figs. 3 and 5) formed from the". metal of the supporting plate 49. As

the sidewalls of the hopper rise perpenunder the right and left dicularly from said slits, these fingers lie hand ends of the stencil plates or work sheets. The front of the hopper extends just forward of the free ends of-the fingers 73, whereas the rear wall of the hopper is adjacent to the flange 63.

Sprmgfingers' 74 are bent downwardly at the rear ends 75, thereof and are secured at their bent' ends to the depending flange column of 63 by screws 76, the fingers extending forwardly above the fingers 73 and on past the ends of said fingers, beneath the extreme platen roller, terminating near fingers thereof and constitute supports for the stencil plates 77 when said stencil plates are resting in the hopper and also when th platen.

ey are being fed forward to the The stencil plates are each formed with a cardboard frame 78 having I a'reot'a'ngular central portion "79 which is covered bythe sheeto r paper that is pasted stencil to the frame 7 8 as indicated in Fig. 7. The

plates are arranged one on top of another, as shown in Fig. 3, and a'weight pressure toward the platen. the fingers 73 with a suitable tool the width 80 which corresponds in shape to the inside opening of the hopper is arranged on top of the pile of stencil plates so as to force themdown as the stencil plates successively feed from the hopper, a finger piece 80 being provided on the weight to facilitate its removal whendesired. Said weight is also shown-provided with corner posts 80 to prevent its being fed out through the slit when the pile of stencil plates is. exhausted. The forward ends of the fingers 74 are bifurcated as indicated at 81, the slots in the bifurcated ends of the fingers extending beneath the serrated or toothed feeding wheels 48 -at-t-he ends of the platen and the fingers exerting an upward spring By bending of the slot 70 may be regulatedto permit 2) so as to 'prbpreferably half rotation of the platen at a time. The tension 0 the spring fingers .74 may be varied bybending them in the" p e same way inorder to regulate the pressure. I

exerted by the fingers and cause them to properly cooperate, with the feed wheels 48 to effect a forward feed of the stencil plates.

' It will thus be understood that the bottom of the hopper is entirely open except at each side thereof where the spring fingers 74'extend beneath the hopper and constitute a support 'for the column of stencil plates and that said fingers actwith the side walls of the hopper as a guide to direct the stencil plates in their forward movements through the slot 70 at the bottom of Each side wall of the hopper has a horizontal slot near the bottom thereof which receives-an inwardly projecting finger or follower 82 (Fig. 11) formedas a part of a reciprocating slide 83'that moves fore and aft of the machine on the supporting plate 49 and is guided in such movementby shouldered and headed guide screws 84, the stems of said screws passing through slots 85 in the slides and being received in openings 86 (Fig. 5) in and cooperating with nuts 87 (Fig. 3) beneath the supporting plate.

slides 83 is provided with an tending ear or lug 88, at the thereof (see Fig. 11). An outwardly extending pin 89projects from the ear 88 for the attachment of one end of a coiled conupwardly extractile spring 90,' the opposite end'ofs id spring being connected which projects outward the lower end thereof The tension of the springs 90 is thus exerted to normally maintain the reciprocating discharging devices or slides 83 1n their rearmost positions, as shown in Figs. 2 and 11, where the inwardly to a pin 91 (Fig. 2)

projecting fingers 82 thereof are just in the rear of the lowermost stencil plate and where they wiil engage the rear edge of said stencil late it forward movement of the slides 83 will, therefore, bring the fingers 82 into engagement'with the rear edge of stencil plate and will fo-rc'e this lowermost stencil plate forward in a flat state along'the fingers 74 and through the slit or opening 70, the side edges of the stencil plate being brought into cooperation with the serrated feed wheels 48. Each end of the platen carries two fixed actuating devices or pins 92 which are located diametrically opposite each other, as shown in Fig. 2. tion of the parts is such that during each at each end thereof wiilfioe operation with the lug 88 Each of the forward end from the hopper at when the slides are moved forwardly;

the lowermost The relaone of the-pins. brought into co j}: on its associated the hopper.-

carrier 83 and both carriers will be simuL' j taneously forced forward to effect a'iffo'rward feed of the lowermost stencil 4 1 g will restore the slides I are released from the pins continued forward feed movement of the platen will cause the pins 92 which are in engagement withthe lugs 88 to be disengaged from said lugs, when the springs to normal position, as shown in Fig.- 3, ready to engage the next or lowermost stencil plate in the hopper. A forward feed of a stencil plate 1n the manner just described forces it to a position where the forward portion of each side,

into engagement edge thereof is brought wheels 48 on the with the serrated feed platen as heretofore stated, and a further rotation of the platen produces a forward feed of the stencil plate in a fiat state through the actuation of the serrated feed wheels and the cooperation therewith of the spring fingers 74 which force the sides of the stencil plates into engagement with the serrated feed wheels. A continued forward feed movement of the platen will eventually discharge the engaged stencil plate into the chute 57 and it will be directed in such movement under a guide finger 93 that projects at its free end toward the platen and is secured at its forward end to the chute by a screw 94. 7

As heretofore pointed out it requires but a half rotation of the platen to effect a forward movement of the slides 83 to bring one of the stencil plates to position to cooperate with the platen. During the forward feed movements of a stencil plate with the platen the other set of oppositely disposed pins 92 are being rotated to a position where they will cooperate with the lugs 88 on the slides 83, when said slides have effected a forward movement of the preceding stencil plate and 92 which actuated them.

The platen shaft 36 has a line spacing wheel 95 secured thereto near the right-hand end of the shaft. This line spacin wheel, as shown in detail in Fig. 4, is provi ed with two series of ratchet teeth 96, 96 and 'intervening plain or untoothed portions 97,

97 on which theline spacing pawl is adapt-- ed to ride freely without transmitting mo tion to the line spacing wheel as will hereinafter more clearly appear. A detent roller 98 is carried by a spring 99 secured by a screw 1.00 to a downwardly and inwardly J projecting lug 101 formed on the plate 38.

The detent roller bears against the periphery of the line spacing wheel in the usual manner. A line spacing lever 102 is pivoted at 103 to the and downwar ly extending arm or handle 104 by which. it maybe actuated. An upwardly extending arm- 105 on the line spacing lever projects above and to one side of the line spacing wheel 95 carries a line 'spacing pawl 106 of the lever at 10 The pawl has a leaf 65 spring 108 secured thereto at 108 and the:

ivoted on the inner side late 38 and has a forwardly free rearwardly projecting end of the leaf spring is received under a pin 109 which projects inwardly from the line spacing lever, the tension of the spring being exerted to force the nose of the pawl toward the line spacin wheel. A stop pin 110 projects inwardly. rom the line-spacing lever and constitutes a stop for the awl 106 to limit the upward movement of t e engaging nose thereof relatively to the lever. "An adjustable device or stop 11.1 coacts with the tail 112 of the pawl and determines the extent of line spacing movement that ma be given the platen at each actuation o the lever 104105. In the normal position of the parts the upward pressure of the arm 104 brings the tail of t e pawl against the stop 111 and forces the pawl against the tension of its spring 110 as shown in Fig. 3. \Vhen the line spacing lever is actuated by turning it on its pivot 103 and against the tension of its spring 113, the tail of the pawl will be moved away from the stop 111 and the pressure of the spring 108 will be effective to force the nose of the pawl into engagement with one of the teeth of the line spacin ratchet wheel and a further movement 0 the line spacingrlever will effect a rotation of the platen. he adjustable device for determimn the extent of line spacing movement is s own in detail in Fig. 6 and comprises the stop 111 .and a rotating carrier 114 therefor, the pin being off-set rom the center of the carrier. This carrier is provided with a stem' or pivot 115 which is re ceived in a bearing in the plate 38 and projects through the same to the outer side thereof where it is threaded at 116 for cooperation with a finger piece 117 by which the device may and rotated in its bearing to set the stop 111. in different positions. A coiled expan sion spring 118 surrounds the pivot 115 and bears at one end against the finger piece 117 and at its-other end against the plate 38 to exert an outward pressure on the device.

The carrier or member 114 is provided with an outwardly projecting pin adapted to be seated in any one of several openings in the plate 38. By an inward pressure on the piece 117 the member 114 may be moved to the left in Fig. 6, thereby withdrawing the pin 119 from the opening 120 in which it is seated. The finger piece 117 may then be turned to bring the stop 111 in the desired position to determine the extent of line spacing movement which is to be effected at each actua-' tion of a line spacingl lever, and when pressure isreleased on t e finger piece the pin 119 will be seated in an opening 120-to secure the device against rotation in its adjusted position. i It will be understood that by adjusting the device in the manner point 108 into contact with its stop be moved longitudinally 119 which is exerting"- seas to force the sleeveand disk to the left. The pin 124 extends"through the disk so as to provide alcckingpin 129 which into engagement with the ratchet wheel, de-

ending on-the adjustment of saiddevicei hile I have shown one means for accomplishing this purpose it should be under stood that any suitable'means for determining the extent of line spacing movement may be employed.

The stencil plates have room for four or five lines of writing, and saidplates are fed from-line to line by the line space mechanism just described. When one stencil plate has been perforated, it is fed out of the machine and another is fed up to the first writing line by turning one of the finger wheels 39, 40. In order to arrest the platen when the first writing line is beneath the platen in position to be struck by the perforating types 13, I have provided a stop device which positively arrests the platen shaft'at this position and prevents further turning of said shaft by the finger wheel until after the linespace lever is operated. This stop device'is adjustable to vary the position on the stencil plate of the first writing line.

Projecting rearwardly and downwardly from the line spacing lever is a stop or arm 121 secured to the line spacing lever at 122. In'the normal position of the line spacing lever this stop or locking arm or abutment 1.21 is so positioned that it will extend into the path of stop or looking pins or abutments 123, 124 which are carried by a disk 125 which is locked to rotate with the platen. It will be understood,'- therefore, that a forward rotation of the platen by the finger wheel will bring one of the stop pins into contact with the rear end of the stop arm 121 and a further movement of the platen in this direction by this means is'prevented by such contact; the line spacing lever normally bearing against the member 114, as shown in Fig. 3, to prevent further upward movement of 'the rear arm of said lever. The disk 125 is rigidly connected to a sleeve 126 which surrounds the platen shaft and extends through a bearing opening in the plate 38, the outer end of the sleeve being provided with a finger piece 127 by which .the sleeve and the disk 125 connected there- 'to may be moved longitudinally along the shaft.

A coiled spring 128 surrounds the platen shaft and bears at one end against the hub of the finger wheel 40 and at its opposite end against the finger piece 127 is'adapted to be received in any one of a number of openings 130 in the line spacing wheel so as to rigidly connect the disk and pins'l23 and 124 carried thereby, with the line spacing wheel. Sight apertures or openings 131 are provided on diametrically opposite sides of-the disk 125 in the periphery thereof'j-and these sight openings are adapted to register with the indices or index numerals a on the outer face of the line" spacing wheel. The means just described affords an adjustment of the looking pins 123 and 124 relatively to the line spacing wheel and determines at what period in the rotation of the platen the pins 123 and 124 will be brought'into contact with the stop arm 121- and determines at what period in the forward rotation of the platen it will be arrested.

It will be seen that the indeii numerals a are arranged as follows O, 1, 2, 3. An adjustment of the disk 125 so that a sight aperture l3l will register with one of these index numerals positions the stops 123 and 124 and indicates at how many line space distances from the top of each stencil plate the first line of writing will appear, and, indirectly, how many line spaces may be written on each stencil plate before the line spacing mechanism will be rendered inoperative to turn the platen farther, as will hereinafter more clearly appear.

When the line spacing lever is in the normal position the stop arm 121 is in the path I of the stops 123 and 124 and will arrest the platen in its forward rotation when such forward rotation is efi'ected-by either of the finger wheels 39 or 40. Although the platen can no longer be given a forward rotation by the finger wheels when one of the stop pins 123 ,or 124 contacts with the end stoparm 121, the line spacing lever is nevertheless free to be actuated at this time. Thus an actuation of the line spacing lever at this time lowers the stop arm 121 away from the engaged stop 123 or 124 before motion is communicated to the platen and the further movement of said line spacing lever effects a line spacing movement or forward feed of the platen.

A rotation of the platen for a single toothed A ace distance moves the stop 123 or 124, which was engaged by the stop arm, forwardlya corresponding distance and when the line spacing lever is released it will be restored to the normal position; a cut-out portion or recess 132 in the stop arm registering with the formerly. engaged pin 123 or 124, so that the pin and stop arm will not interfere with the line spacing lever being restored to normal position. The line spacing lever' may be employed to effect a forward feed of the platen until one of the blank portions97, 97. isbrought into the path of the line spacing pawl when the line spacing mechanism is rendered inoperative and a further forward feed ofthe platen operates with the cams 14'2 cannot be effected by this means. The operator will therefore understand that further writing on the stencil-plate cannot be effect ed, or that the last line on the stencil plate 5 has been reached. While the line s acing mechanism is ino erative to effect a urther forward'feed of tile platen the finger wheels 39 and 40 may at this time be employed to turn the platen forwardly in order to discharge the last written stencil plate to the chute and to automatically feed the next stencil plate forward into cooperation with the platen and into position to receive the first line of writing. In other words, the operator may rotate either of the finger wheels 39.01 40 to produce a forward movement of the platen until the next succeeding stop pin 123 or 124 is brought into engage-- ment with the end of the stop arm 121 to arrest further forward movement of the platen through the finger wheels. This 'movement is sufiicient to discharge the stencil'plate which has been written and to antomatically feed the next succeeding plate forward to proper position to receive the first line of writing.

It will be observed thatone stencil plate is fed out of the machine at each half rotation of the platen, and that only a few lines are written on each stencil plate, so that the types 13 never strike the platen except along a few lines on each half thereof. The slot 41 is situated between these two areas in a part of the platen that is never struck by the ty es.

Vhen a stencil plate has been fed free of the platemit falls into the chute 57, and I have provided means for disehargingit from the left hand end of said chute. The discharging device comprises a Vibratory or oscillating arm 133 pivoted at 134 and ressed in the direction of the arrow in ig. 2 by a spring 135, one endof which is secured at 136 in an opening in the supporting plate 49, the other end of the spring being secured at 137 to the vibratory arm The forward free end of the vibratory arm has an upturned portion 138 to assure. contact with the stencilplate. From an examination of Fig. 3 it will be seen that the arm 133 is bent at 139 so that the free end of the arm may extend down in and adjacent to the bottom of the chute 57. A hub 140 is secured. by a screw 141 to the platen shaft 36 and this hubv carries two oppositely disposed cams 142, 143. The cam 142 is formed as an extension of a plate-like portion 142 (Fi 9) that is located in a plane at rightang es to the shaft'36 and in a like manner the cam 143 is provided with a plate-like member 143 which is likewise in a plane at right angles to the shaft 36. An upwardly projecting half cylindrical pin 144 is carried by the discharging device 133 and coand 1.43 as tin-.5;

striking against are rotated witlrthe shaft 36 to more the vibratory discharging device against the tension of the spring The parts are so timed that while the stencil plate is being fed forward by the serrated feed wheels 43 one of the cams 142 or 143 will engage the pin 144 and will positively more the vibratory arm 133 against the tension of the spring 135. After the stencil plate engaged by-the feed wheels 48 has been discharged into the chute and under the guide finger 93, the cam which engages the pin 144 will be moved to a position where the abrupt drop or straight edge thereof will. clear the pin, thus relmsing it. The arm will be forced by its spring in the direction of the arrow in Fig. 2, thus bring the upturned end 138 into engagement with the right-hand edge of the stencil plate and the force of the arm 133 the stencil plate will force it along the chute 57 and discharge it from the machine at the left-hand end of said chute. The movement of the arm 133 just described is arrested by the pin 144 engag ing the plate-like portion 142- or 143 of the next succeeding cam so that it is in a position to cooperate with the next succeeding cam during a further rotation of the platen in order to place the spring 135 under tension and then automatically release the arm to discharge the nextstencil plate that has been fed fdrward into the chute by the serrated feed wheels 48.

Having described'the construction I Wlll now proceed to describe in detail the operation of the machine.

The operator first determines how many line spaces are to be written on each stencil plate or work sheet 77 and where the first line of writing is to appear by adjusting the disk, carrying the stops 123 and 124, on the line spacing wheel T ins if the operator desires to produce the first line of writing at, say, two line space distances or the distance of two teeth of the line space wheel from the top writing edge of the stencil plate, the disk'125 will be set so that the index numeral 2 will be exposed at the si ht openings131 in the disk and when the filaucn has been rotated forwardly until it is arrested by one of the stop pins 123, 124 coming into contact with the stop arm -1J1 the stencil plate will be properly positioned to receive the impact of the puncturing points It the line indicated. After this line has been completed the operator may actuate the line spacing mechanism to feed the stencil plate to write or. perforate other lines. After three line space distances or the distance of three teeth of the line spacing ratchet whcr-L one of the blank portions 97 or 97 of the ratchet wheel will be brought into coti 'icration with the line spacing pawl and a further movement of the platen cannot be effected by the line spacing mechanism. The forward sEsT AVAILABLE cos feed of the platen thus roduced by the line spacing mechanism wil bring the stencil plate to a position where the last line of writing may be produced near the lowermost portion thereof or that portion of the stencil plate which is near the lower edge of the frame 78. No matter what adjustment is given to the stops 123, 124 the line feed mechanism will always be rendered inoperative before the lower edge of a stencil plate. is brought to the printing line by one of the blank or untoothed portions 97 or 97 being brought into cooperation with the line spacing pawl. The operator may effect a further forward feed of the platen by the finger wheels 31) or 40 after the last line of writing has been produced on the stencil plate in order to discharge the completed stencil plate into the chute and to automatically effect a forward feed of the next succeeding stencil plate. After the mechanism has been set. in the manner described the operator may fill the hopper with stencil plates or work sheets and lace the weight in position thereon. The rst stencil plate is fed to operative position to receive the first line of writing by the combined operation of the line spacing mechanism and the finger wheels 89 or 40; the line spacing mechanism being actuated first and the final movement of the stencil plate being effected by either of the finger wheels. \Vhen a further rotation of the fin er wheels is prevented by one of the loc ing members or stop pins 123, 124 coining into contact with the stop arm 121 the stencil plate will be in position to receive the first line of Writing and the slides 83 which moved said stencil plate forward will have been released from the pins 92 which actuated them and will be restored by their springs to the normal position shown in Fig. 2 where they are ready to effect a forward feed of the next stencil plate which is the lowermost stencil plate supported on the spring guide fingers 74. The operator may now proceed with the writing and as the successive lines are written and the line spacing produced by the line spacing mechanism, one of the blank portions 97 or f)? on the line spacing ratchetwheel will be brought to a position Where the. line spacing pawl will cooperate therewith before the bottom of the stencil plate has been reached. This will render the line spacing mechanism inoperative to produce a further forward feed movement of the platen, thus notifying the operator that the last'line on the stencil plate has been reached. After this line has been completed the operator will turn the platen forwardly through the finger wheels 39 or 40 until further movement. is arrested by one of the stop pins 123, 124 coming into contact with the stop arm 121. This last mentioned movement of the platen through the finger wheels 39 or 40 is effective to bring the other set of pins 92 into contact with the upwardly pro ccting lugs or cars 88 on the slides to si1nultaneously move them forward in order to automatically effect a forward feed of the next stencil plate as the completed plate is being fed forward into the chute by the rotation of the platen. The same movement is also effective to move the discharging device 123 against the tension of its spring and the parts are so timed that when the completed stencil plate is discharged into the chute and the next succeeding stencil plate is in operative position to receive the first line of writing the discharging device 183 will be automatically released and will strike the stencil plate in the chute and drive it along the chute and out of the machine. After this operation has been completed further forward rotation of the platen by the actuation of the finger wheels is prevented through the engagement of one of the stop pins 123 and 12 i engaging the stop arm 121. It is necessary, therefore, to proceed with the writing and to effect a further forward movement. of the platen through the line spacing mechanism. These operations are continued until the stencil plates are exhausted and the front. of the hopper being open enables the operator to observe when it is necessary to refill the hopper.

It. will be observed from the foregoing description that the finger wheels 39 and 40 and the line spacing mechanism are alternately operated to effect. a forward feed movement of the platen; that after a predetermined extent of movement. by either of the devices in question said device is rendered inoperative to effect a further forward movement of the platen until the other device is actuated; that in this manner the stencil plates are successively brought to proper position to receive the first line of writing and as the writing proceeds the stencil plate in operative position is arrested from further movement before the bottom thereof is presented to the print.- ing line: that after the stencil plate is completed the other device, or either of the finger Wheels 39 and 40 may be employed to effect a further forward feed of,tbe completed stencil plate to discharge it from the platen into the chute; that the plate in the chute will be automatically discharged from the machine and the next succeeding stencil plate will he autoi'natically brought into operative position: that the predetermined extent of forward movement of tilt platen effected by said finger wheels is determined by the cooperation of the locking devices 121, 123 and 12f and positiveli regulates the positioning of the stenci plates in the machine. to receive. the first aiu ast lines of writing and that the adjust ment of the disk 125 is effective to vary th positioning of the stencil plate corresponding to the character of the work to be produced.

It will also be seen that the'feed of the work sheets or cards from the hopper to the platen is positively effected by the positive engagement of the positively actuated fingers 82 with the cards and that the cards or stencil plates are maintained in a fiatstate from the time they are received in the hopper until they are discharged from the machine as completed stencil plates.

Various changes may be made without departing from my invention.
