AUTOGRAPHIC REGISTER.

r 'all Iwhom Iz'tmay conce-m v-fBe it known that I, WILLIAM RITSCHARD,

-faf'citi'zen vof the United States, residing at New York, in'the county of New York and -State'of N ew York, have invented a new and useful Improvement in Autographic Regis-vA of rolls of paper are supported i'n a casing,

and the webs of paper carried forward over a platen `or writing surface. Sheets of carbon paper or other manifolding material are interposed between the webs of paper so that the original record or writing`of the top web of paper is transmitted to the lower webs of paper, and when such record has been made on the portion of paper over the writing surface, the several webs of paper are carried v forward to bring-a fresh portion in position,

one of the Webs being rewound on a record roll within the casing, and the remaining webs torn ofi'.

One of the objects of my invention is the provision of new and improved means for feeding th'e paper forward over the writingV surface.

Another object of the invention is the provision of an improved device for supporting the record roll withinv the casing.

.IjiLstill further object of the invention isv toprovide means to vengage the inner surfaces lof the hollow tubular cores of the supplyrolls and act as a friction brake or ref tarding device'for the rolls.

Other objects of the invention will appear hereinafter, the novel combinations of ele- -40 mentsE being set forth in the appended claims.

Referring to the accompanying drawings in which is illustrated a construction embodying one form of my invention,-Figure i 1y is a side elevation of the machine with the adjacent side of the casing removed; Fig. 2 isa plan view; Figs. 3 and i are front and rear end elevations respectively; Fig. 5 is a sectiona-l side elevation vof the opposite side l ,n from that shown in Fig. 1. part being broken away, and certain parts of the machine being omitted for the sake of clearness; F ig. 6 is a detail showing means for automatically operating the tearing blade; Fig. 7 .isa detail view ofa ret-arding device for a supply roll;

Fig. 8 is a sectional detail view of the record roll; and Fig. 9 is -a fragmentary detail view of lthe paper clamp.

Y The casing comprises side plates A and B connected by braces l, 2 and 3, 4, located at opposite ends of the casing and which forni with thev side plates a rigid frame. The bottom C of the casing is made removable in ,order to permit the supply rolls to be in- Serted or removed, and as here sliownis slidable endwise in the guides 5. The ends 6 and 7 of the casing are preferably hinged near the upper corners of the side plates A, B as b v means'of the lugs 8 formed on or secured to the end plates, and journaled in the upper corners of the side plates. This thence over the writing surface and forward to the guide roller 13 at the front end'of the machine and down to the record roll H. The manifolding material which may consist of a roll of carbon paper 14 is contained in a receptacle 15 secured to the side of the casing. The roll 1l:` in this vinst-ance comprises two sheets of carbon paper the free ends of which extend across the writing surface andare interposed in the usual way between the webs of paper from the supply rolls. At the sidel of the casing adjacent to the carbon roll, the sheets of carbon are securely .held or clamped in position by ymeans of a bai- 16 which ts between a bracket 17 and the side of the casing. EX- tending along the left hand side of the writing surface is a supporting member 18 se-- cured to the side A of the casing by means of depending arms 19 which are curvedoutwardly to space said member from the side of the casing. The ends of the carbon sheets are clamped between the-supporting member 18 and a clamping bar 20 pivoted at 21 to the member 18. The opposite end of the bar 20 is lvieldingly held in position by a. spring 22 which pulls the -bar toward the number 18 but permits the bar to be swung back and .the Carbon sheets `placed in position. Any

other suitable means may be used for hold-` B and the supporting member 18 respec'- tively. The platen 12 ispreferably formed with an integral extension 12 at its forward end, offset to provide room for the paper clamp. in position over the platen 12 and spaced therefrom a suflcient distance to permlt'the webs of pa )er to pass freely between said frame and txhe platen.

'lhc paper clamp G is supported by a carrying trame comprising bars 26 and 27 a cross bar or brace 28 at the front end an a bar 2f) which forms the lower or stationary member of' the paper clamp. The bar 29 is provided at its ends with depending flanges 3l by means of which it is rigidly secured to the frame. An additional race 32 may be used in front of the aper clamp if desired, and a sheet metal p atc 88 may be secured to the braces 28 and;32 by screws 34.' rl`he upper member 35 of the paper clamp is hinged to the lowermember by means of lugs or bosses 36, 37, secured to or formed on the upper and lower clamping members, and a hinge rod 38. Coil sprmgs 3f) serve to hold the clamping. ed es of the jaws firmly in engagement wlth't e pa er, and if desired the engaging surface or e ges of the clamping jaws may be roughenedor lmurled as shown, or rovided with any other well known expe ient to prevent the paper from slipping.

'lhe carrying frame is adapted to have a longitudinal reciprocating movement and is supported and guided on one side by the ribs 40, 41 on the inner surface of the side B of the casing. The o posite side A of the casing is provided witi ribs 42, 43 spaced apart to receive a similar rib 44 formed on the bar 27. The lower edge of the Ibar 27 is formed with rack teeth 45 which mesh with corresponding teeth on the drive pinion 46. The pinion 46 is keyed to a shaft 47 journaled in the sides of the casing and provided outside the casing with a hand crank 48.

Referring to Figs. 1 and 2 a-short rockshaft 4f) is journaled in lugs 50 on the inside of the rack bar 27. This rock-shaft has secured thereto an outwardly extending trigger 51, and a rock arm 52 which extends inwardly beneath a finger 53 secured'to the u per clamping jaw 35. Secured to the s e A of the casing is a cam Msadapted to engage the trigger- 51'at the end of the forward movement 'of' paperl clamp and :rock the shaft 4f) and arm 52. .This movement of the arm 52 lifts .thefinger v53 and-opens the paper clamp. During the return move- A rectangular fraaie 25 is secured:

ward by .the cam 54, the front end of the latch is tilted downward until the trigger 'passes beyond the latch and permits 1t to swing back by gravity to its horizontal position and preventthe trigger from moving up above the r1b 57 as the paper clamp 1s returned.

. The method of supporting the supply rolls within the casingwill now be described. The spindles 58 which support these rolls each has an end flsquared or flattened to fit in a correspondingly shaped opening in a bearing plate 60 secured to a lug 61 on the side B of the casing. The other end of. the spindle is held by a socket 62 extending through an o ening in the side A of the casing into a ox 63 cast integral with the casing. A stem 6l on the socket (l2 extends outward through the box 63 and is provided with a thumb piece 65. lA coil spring 66 holds the socket normally in engagement with the spindle but permits the spindle with its roll of paper to be readily inserted orv removed. -Mounted on the spindle 5S are spools or cores 67 and 68 which are free to rotate on the spindle. These spools are made-of a size to fit closely in the tubular cores upon which the commercial rolls of paper are usuallywound. In order to prevent the roll of paper from turning independently of the spools one of the spools, as 68, is preferably formed with'recesses 69 in which are secured leaf springs 70 bowed so asy to extend outward beyond the periphery of the spool and frictionally engage the core of the paper roll.

Between the spools 67 and 68 is placed a friction device for preventing the roll of paper from turning too freely. This device comprises a tubular sleeve 71 and end flanges 72. The sleeve 71 has a portion cut awa)r from one side, and the spindle 58 has a corresponding flattened portion 7 3. The sleeve fits on the spindle with the edges formed by the cut away portion in the same plane as the flattened surface of the spindle. A friction spring 74 has one end secured to the fiat surface formed by the sleeve and spindle and its free end is preferably provided with a roller 75 which normally projects a short distance beyond the peripheries oft the spools 67, 68. lVhen the roll of paper is placed on the spools the roller 75 bears against the inner surface of the tube on which the paper is wound and prevents the rollfrom 4turning too freely. 'The flanges 72 protect the friction spring, but the sleeve and flanges may in some cases he omitted, the spring then being secured directly to the spindle. The relative position of thesprings and spoolson the shafts 5S '4 a disk 92.

5 per. The spools are held in position on the y spindle by the collars S2. j

The lrecord roll H which is formed by the web of paper from `the supply roll F. is wound on a spool 7.6 of wood or other suit- A10 able material. This spool has a. longitudinal slot to receive a wedge or flat bar 77 bv meansof which the web of paper is secured to the spool. A recessTS in the spool permits the bar 77 to be grasped b v the thumb and linger and thereby readilv removed.

The spool 76 is vmountedon a spindle 79, one end of which is journaled in the side A of the casing. The opposite end of the spindle has a bearing in a circular plate or disk S0 removabljv held inthe side B of the casing.

vThis side B is formed with a circular' opening S1 somewhat smaller than the disk 80, said opening having recesses S3 to Areceive lugs 8st formed on the bearing disk S0. The

,disk 8O is secured in position in the side B of the casing by projecting the lugs SJC through the recesses83 and then rot-ating the disk to bring the lugs Si out of alinement with the recesses S3, as indicated in Fig. 1. The disk 80 is also provided .with

a central bearing 'S6 forthe end of the spindle 79, and with outside lugs 85. Loosely mounted on the inner end of the spindle 79 is a toothed gear wheel ST meshing with an idler pinion 88 which in turn The gear meshes with the rack-teeth 4:5. wheel ST carries a disk S9 provided with va spring pawl 90 which 'engages ratchet teeth 91 formed on the lateral surface of The disk 89 which is secured to the gear wheel 8T ma)r be replaced b v a seg- `ment or an arm if desired. The disk 92 which forms ra driving member for rotating the spool 76, is preferably provided I with a ber plate 93 in frictional engagement with a similar plate 9i secured to the spool 76. The gear 92 is also provided ywith ratchet teeth 9i 4on its periphery which are engaged bv a spring pawl 95 to prevent backward rotation of the disk. spring pressed disk 96 is placedbetweenv the outer end of the spool 76 and the bearing plate 80 to hold the fiber plates 93 and 91' in frictionalcontact.

y lT he tearing blade 97` is pivoted in the casing and its tearing edge is normallv held up bv the spring 98. A handle 99 is used to swing the blade down to tearing position. If desired, means may be provided for moving the blade automatically. One arrangement which may' be used for this purpose consists of a lever 100 having one end con4 nected by a link lOl-to the tearing blade 5 and 'the other end in position to be moved by apin 102 on the gear Wheel 46 and move -blade 9T. l placed in position and the free ends of the the tearing edge down as the paper clamp reaches its forward position. 'l q To prepare the aut-ographic register for use, the Vbottom C ma)v be removed and the spindles 58 with their spools 6T. GS, taken out of the casing and the supply rolls D E, F placed thereon. The rolls with their spools and supporting spindles yare then placed in position in the casing. The web f from the supply roll F is then carried up over the roller 11. and forward over thev platen 1:2. between the clamping jaws 29 and 35, over the front roller 13, and down to the spool T6 to which Ait is secured by means of the clamp bar '78.- A carbon sheet is next placed in position over the web f. The web of paper e from the roll E vis next placed in position, as shown with its free end extending about to the tearing edge of the Another carbon sheet is then two carbon sheets secured b v the clamp bar 20. and iinallv .the web d is placed in position vand the clamping jaws allowed to irmljv grip the/three webs of paper from the suppl)v rolls,v The machine is now ready for use. Whenj'the portion of the paper in position over the platen has been written upon and it is desired to feed the paper forward. the hand crank $8 is turned to rotate the gear -lG and move the rack-bar 27 forward. The rack-bar carries with it the paper-clamp and the three webs of paper which are securel)1 held thereby. During this forward movementof the paper clampV and its supporting frame, the trigger 51 moves above the rib 5T until it reaches the cam 5l which moves the trigger downwardly to open the paper clamp as before explained. The ends of the webs d and e are now free and the operator'grasps them with one hand at the recess 35 while with the other he moves the blade 9T down against the paper and then tears ott the two webs. Thecrank i8 maj7 now be turned backward to return the parts to their initial position. During this return moven'ient the trigger 51 rides along the under surface of the rib 5T and holds thev paper-clamp open. As the paper-clamp reaches the limit of its ret-urn movement the trigger 51 passes bevondthe rib 5T and permits the clamping jaws to snap shut on the three webs of paper readv for another opera-tion. It lwill'A be observed that the tearing edge of the blade 97 is a short distance forward of the initial position of the clamping jaws. and that the upper clamping jaw is up enough to readily clear the ends of the paper, which insures that all the webs will be caught bv the clamp when the trigger 51 is released.

During` the forward movement of the rack-bar the gears 88, 487 are operated to rotate the record roll-H and take up the web f as fast as it is fed forward by the paper clamp. The friction driving connection between the spool 76 and the disk 92 )ermits the backward rotation of the spool reiatively to the disk which is necessary as the record roll increases in size and the peri heral speed of the record roll relatively to t at of the paper clamp increases. The pawl permits backward rotation of the gears 87, SS independently of the disk 92, while the pawl positively prevents backward rotation of said disk.

rlhe paper-clamp and means for operating it form an important feature of the ypresent invention as they form a means for osilively feeding the paper forward wit iout the. slipping or creeping that occurs when the paper is fed forward in the usual way by a pair of rollers. rlhe present arrangement also insuresl the paper being moved forward exactly the same distance each time, and that all the webs shall be moved an e( ual distance. This is specially desirable when printed forms are used and it is necessa ry to maintain the several webs in alinement and move them forward the same distance each time the machine is operated.

The present invention may readily be adapted to autographie'registers having any desired number of webs of paper more or less than those shown in the drawings, and certain features of the invention may obviously be applied to a machine using a single web of paper, or to a machine in which all the webs are torn off as they are used, and

' I wish therefore to have protection on all such forms of the invention as come within the scope of the appended claims.

I desire further not to be limited to the exact construction shown, as various changes in the details of construction and arrangements of parts might be made by those skilled in the art without departing from the s irit and scope of the invention.
