Specification of Letters Patent. I

Application filed May 20,1905. Serial at. 261,885.

To all whom it may concern:

Be it known that I, WILHELM A. SCHMIDT,

' citizen of the United States, and resident of Ilion, in the county of Herkimer and State of New York, have invented certain new and useful Im rovemen'ts in Writin -Machines,' of which t e following is a spec cation.

My invention relates to writing machines, and its main object is to .provide a machine having a 'flat platen which is particularly adapted for employment with a stencil sheet or other work sheet too inflexible to be-readilyfed around a cylindrical platen.

To this and other ends'the invention resides in the features of construction, arrangements of parts and combinations of devices, hereinafter fully setlforth and particularly pointed out in the claims.

. In the accompanying drawings, Figure 1 is a fragmentary top plan view of a writing ma chine embodying one form of my invention.

Fig. 2 is a front elevation of the upper portion of the machine, the p aten being shown raised, exposing the wor Fig. 3 is a sectional side elevation taken on a plane repre sented by the line ac-x in Fig. 1. Fig. 4 is an enlarged sectional side elevation of the platen carrier and the platen, parts being omitted. Fig. 5 is a bottom plan view of the platen showing the work retaining member levers 4 are pivoted at 5' in the rear of thebase, each key lever being provided with a restoring spring 6. A link 7 connects each of the key levers with a type bar 8 pivotally secured in a hanger 9, the series of hangers being circularly arranged and fixedly mounted on the top plate 3. The free end of each type bar is provided with a type 10,the

working face of the type having a puncturing or cutting surface, which surface, as herein shown, com rises a plurality of fine needle points 11. lhe free ends of the type bars are supported, when in normal position, by a ciruclar type rest 14.

Fig. 7 is an enlarged fragmentary Patented May 5, 19 08.

The puncturing elementsor t e bars are adapted to cooperate with the un or side of a flat platen or stencil support, designated as a whole by the reference 15, and comprising athin web like m6t8tl' portion 16' connecting heavier bar-like side portions 17. The weblike portion is somewhat thicker at the front and rear edges than in its body portion. As best shown in Figs. 2 and 4, the inner faces of the side portions 17 are formed beneath 5 the web 16-with grooves 18 which receive a backing plate 19 preferably made of wood.

Upon the backing plate 19 are placed a plurality of layers 20, 21 and 22 of a softer mar terial, preferably of fabric such as canvas.

The layers of the fabric progressively decrease in thickness, the innermost layer 20be-- ingcomparatively coarse and heavyand the outermost layer or facing'22 being comparatively thin and smooth. A bearing plate 23 is secured by screws 24 to the under side of the righthand side portion 1.7. Hinged to the bearing plate is a backing retainer or pad holder 25 which is held pressed against the facing 22 by a latch 26 pivoted to the under 30 face of the left-hand side portion 17 and adapted to engage the left-hand edge of the pad holder or retaining frame 25.

' A plate 27 is secured to the rear face of the platen frame by headed screws 28 and serves 5 I as one member of a hinge .whichsnp oits a work clamp. of retaining frame 29. 3O is provided with trunnions 31 which are receivedin bearings 32 projecting from the front of the platen frame. The topsof the trunnions 31 are flattened and a bifurcated latch leaf spring 33, secured to the topof the web 16 by a screw 34, is adapted to engage the. flattened portions of the trunnions when the latch 30 is in normal position, so as to retain '95 said latch in its bearings and in a position to engage the front of the retaining frame or work clamp 29 to hold the latter in operative or working position. A ortion 35 projecting upwardlyfrom the we 16 receives limit- 1 00 ing screws 36.

As best seen in Fig. 2, the outer faces of the right and left-hand side portions 17 of the platen are formed with V-shaped grooves 37 which cooperate with similar grooves '38 formed in guide rails 39 to receive rollers 40. The guide rails 39 are secured to a platenoarrier designated as a whole by the reference 41 and comprisi as best seen in Fig. 1, an-

inner rectangu ar frame 42, which is fixedly secured in an outer frame 43. The front bar 44 of the inner frame 42 is rovided at its ends with ears 45 which are b' rcated to embrace the front bar 46 of the outer frame. Screws 47 are screwed into the bifurcated 43 of the platen carrier; The screws 47 and 50 serve to maintain the inner and outer frames of the platen carrier in a fixed relation. The guide rails 39 are fixed to the under side of the inner frame 42 near its right The two and left-hand ends by screws .53. left-hand screws 53 pass through holes in the frame 42 just large enough to permit their assage and are screwed into threaded perorations in the left-hand guide rail 39, thereby maintaining the two members in a non adjustable relation. As indlcated in Fig. 1, however, the holes 54 in the frame 42 through which the right-hand screws 53 fpass are larger in diameter than the shanks o the "screws so that, until the screws 53 are screwed down into the right-hand guide rail 39 far enough to bring the heads of said s'crews into contact with the upper face of the front and rear bars of thefraine 42, the righthand guide rail 39 may be moved longitudinally of the frame 42, the extent of movement being limited by the walls of the holes54. This construction enables wear to be taken up in the roller bearings connecting the platen with the platen carrier and also permits ready adjust- -ment ofthe bearings when the platen is as-' sembled in the platen carrier. Screws. 55, screwing through the "right-hand side of the inner frame 42 so that their ends abutagainst the outer wall of the right-hand guide rail 39, control the movement of the latter and facilitate the adjustment of the roller bearings. Lugs 56 depend from the front and rear bars of the inner frame 42 of the platen carrier in position to co-act with thelimiting screws 36 so as to limitthe fore and'aft movement of the platen 15 in the platen carrier. A bracket 57 secured by screws '58 to the front bar 46 of the outer frame of the laten carrier serves to support awheel or ro er 59 which, during the movement of the platen from side to side of the machine,'runs on a guide rail 60 mounted on fixed posts 61.

' At the rear of the platen carrier is a truck 62 provided with wheels or rollers 63 which run on a fixed back rail 64. An abutment or arm 65 projectsrearwardly from the center of the truck 62 and is bifurcated to embrace a spool 66 slidably mounted on a fixed guide To rod 52 of the platen carrier, so t-hatsaid car- 1 rier may be swung upwardly about said pivot pins to expose the writing, as indicated in Fig. 2. Set screws 73 in the ends of the truck 62 serve to maintain the pivot pins 72 in afixed position and to prevent rotation of the rod 70. Retaining pieces74 are secured to the backof the truck 62 by screws'7 5 and curve downwardly and forwardly so that their lower ends are under thereby preventing the rollers 63 from becoming disengaged from said back rail.

An may e employed wit my invention. carriage feeding mechanism herein shown rethe back rail 64,

suitable carriage feeding mechanislpi" semblesgenerally that of the No. 6 Remington typewriter. As illustrated in Fig. 3, a

rack 76 is mounted on the truck 62 and normally meshes with an escapement pinion 77 which is operatively connected with an escapement Wheel 78. The latter is adapted to cooperate with escapement dogs 79 mounted in the vertically disposed arm 80 of a pivoted dog rocker, the horizontally disposed arm 81 whereof is connected b with a universal bar 83 which passes om side to side of the machine beneath the series of key levers 4. A strap 84 connects the truck 62 with the l usual s ring drum 85 which tends constantly to raw the truck 62, and with it the platen carrier 41 and platen 15, leftward across the top plate of the machine. The parts of the carriage feeding mechanism are proportioned to permit a step-by-stepmovement of the laten sufficient to properly space the letters fgrmed in the work sheet by the puncturing elements.

- Means for accomplishin movement of the platen an platen carrier in order to provide for the line spacing of the work sheet will now be described. A rod. or

shaft 86 extends from sideto side of the outerrods'82 a fore and aft 7 frame 43 of the platen carrier, passing over the inner frame 42 and over indicated in Fig. 1, bearin cured in the ends of the s through perforations in the thejplaten; As pins 87 are seaft 86 and pass side of the frame 43, said bearing pins having finger wheels 88 fixed on their outer ends. The construction is such that endwise movement of the shaft ,the shaft 86 near its center is a. pinion having a collar portion 90 through aft of the'machine beneath 86 is prevented, while at the same time it may be freely rotated by the finger wheels 88 or by means presently to be (1 scribed. On

fiinion 89, said which passes a set screw 91 by which the pinion is. fixedly secured to the shaft 86. The web 16 of the platen frame is out-away or de ressed at, 92 and in the depression is seats a rack member 93 extending fore and and meshing with the pinion 89, and provided with arms 94 through which screws 95 pass into the web 16, thereby seeming the rack 93 to the platen frame. A short saw-toothed rack 96 pro by ascrew 100 to vided with elongated screw holes 97 is adjustably secured by screws 98 to the web 16 of the platen frame at the left of the rack 93. The teeth of the rack 96 are a line space distance apart. A detent spring 99 is secured the rear of the inner frame 42 of the platen carrier. The free end of the detent spring 99 is provided with a small roller 101 which plays in a depression 102 in the web 1'6 of the platen frame and which engages with the saw-tooth rack 96, as shown in Fig. 1, so as to maintain the platen in any one of a plurality of predetermined line space On the shaft 86 near its right and end is fixedly secured a ratchet wheel member 103 which is represented in detail in Fig. 6. The member 103 is secured to the shaft 86 by a set screw 104 passing. through" a hub portion 105. The member 103 is provided with a circular linespace scale 106 which cooperateswith an indicator or pointer 107 fixed to the bar 46 of the platen carrier to indicate the line when the platen is down in normal position. The ratchet wheel roperf1-08 is in position to be actuated by a ine space pawl 109 which is operated by 'a line s'pace'lever 110 pivotedat 111. The

line s ace actuating mechanism just describe ,that is, the lever 110 and pawl 109, being of a knownconstruction, it 'is deemed unnecessary to describe it in detail. A pointer 112, secured to the bottom face of the left-hand guide rail 67 of the platen frame, cooperates with a scale 113 on the. left-hand guide rail39to indicate the line of writing when theplaten is raised, as shown in Fig. 2. A scale plate 114 is fixed to the work clamp or retaining frame 29 and indicates the letter space position, cooperating with letter space scales and pointers" on .the platen carrier and the truck 62 and which,

being of ordinary construction, are not shown in the drawings. 115 indicates the usual finger piece which is employed in manipulating the carriage.

' To prevent careless or unskilled manipulation of the machine by unauthorized persons, and consequent injury or destruction of the needle-pointed types, I provide means for locking the key levers against depression when it is not desired that the machine be used. Referring more particularly to Figs. 3, 7 and 8, the reference 116 indicates a looking bar extending from side to side of the machine, beneath the ke levers near their forward ends. The en 5 of the bar 116 are secured by screws 117 to blocks 118, the

outer ends whereof are provided with cylindrical portions 119 extending .through perforations in the sides of the base of the ma chine and confined by headed screws 120. Between the head of the right hand. screw 120 and the outer end of the right-hand cylindrical portion 119 is secured a crank arm' 121 provided with afinger piecel22, by

manipulatingwhich the -bar 116 may be revolved in its hearings in the side frames, the cylindrical, portions 119 of the blocks 118 serving as pivots. The right-hand block 118, as illustrated in Figs. 3. and 8, is triangular in cross section, the part furthest from the which, with the inclined faces of the block, forms a cam 123 adapted to cooperate with a flat holding spring 124 secured by screws 125 to the inner face of the right-hand side frame of the machine. project outwardly from the right-hand side of the base in position to co-act with the crank arm 121.

The inoperative position of the locking bar 116 is indicated 1n Fig. 3, wherein, it will be noted, the crank arm 121 is in contact with the forward limiting stop 126, being maintained in this position-by the pressure of the holding s ring 124 against one of the inclined faces of the right-hand block 118. With the parts thus positioned the bar'116 is maintained at a sufficient distance beneath be depressed to operate the machine without interference. When the work is completed and it is desired to lockthe key levers, the operator, by means of the finger piece 122, turns the crank arm 121 rearwardly, revolving the bar 116 in its bearings and causing the cam 123 to press the locking spring 124,t0 the rear, so that the parts may be turned until the crank arm 121 contacts with the rear limiting etc 127 and the spring 124 co-acts with the ot er inclined face of'the right-hand block 118 to maintain the parts in the position indicated in 'Fig. 8, and in Fig. 7 which corresponds thereto. A comparison of Fig. 8 "with Fig. 3 will showthatin the former the bar 116 has been swung upwardly until its-edge is in contact with the underside of the series of key levers, thereby preventing downward movement of the latter untilsuch time as the parts are restored to the positions indicated in Fig. 3. v

The operation of my invention will be understood from the foregoing description but will be briefly explained. The p aten carrier is first swung upward about the Bpiyot pins 72 to the position indicated in and the-spring pressed latch or detent 30 is pressed back to release the Work clamp or retaining frame 29, which latter is swung away from the platen as represented in Fig. 5. The. stencil plate or work sheet, indicated by the reference a, is thereupon placed in posi tion against the facing 22 and the retaining frame 29 is pushed back against the work sheet .and retained pressed against it by the latch 30. The laten carrier is then, returned to normal normal position with the roller 59 in contact with the front guide rail 60, and the carriage, com rising the truck 62, l the platen carrier and t 1e platen, ispushed bar 116 terminating in a rounded portion,,

Limiting stops 126 and 127 the series of keylevers to permit the latter to' cause their associate puncturing elements or type bars, through the links 7, to co-act with the work sheet a, so that the latter will be punctured or cut in the manner indicated in Fig. 2 of the drawings. Each operation of a type bar or of the spacing bar (not shown) causes the escapement members, through the universal bar and its associate train of mechanism, to cooperate in a known manner to permit the-carriage to be moved a letter space distance across the top plate of the machine under the influence of the spring drum 85. When the end of the line of writing is reached the carriage is returned rightward across the top "plate to a position to begin a new line of writing and the line space lever 110 is manipulated to cause the pawl 109 to turn the ratchet wheel 108, shaft 86 and pinion 89, which last, acting on the rack93 causes the laten to move forwardly from the position indicated in Fig. 1 until the detent roll 101 disengaging from the first tooth of the saw-toothed rack 96 engages with the second tooth of said rack. The platen will now be positioned to begin the second line of writing.

The operations above outlined are continued until the writing is completed, whereupon the stencil plate or work sheet may be removed and another one substituted therefor.

Various changes may be made in the details of construction and arrangements of parts without departing from the scope of my invention.
