In the present construction the usual springs for maintaining the paper apron 29 in contact with the platen may be dispensed with so that the paper apron, except when operated as hereinafter described, lies out'of contact with the platen as shown in 3; or, if preferred, in order to prevent the paper apron from being loose on its pivots 31, a light spring or springs may be used to cause the paper apron to bear very lightly against the platen.

A paper table 34 may be mounted on a support 35 at the rear of the platen, and the usual paper fingers 36 may be mounted on across bar 37 at the front of the platen (Fig. 2). i

The carbon roll mechanism proper is carried on a supporting frame which is mounted on the usual brackets 38 for the tabulator stop bar (not shown). lhe supporting frame is vertically disposed andcompriscs side bars 39 which are secured to the brackets 38 by headed screws 40 passing upward through holes in said brackets 38 into the bases of said side bars 39 (Figs. 2 and 7). The side bars 39 are formed with vertical slots or guide ways 41 having angularly disposed orhorizontal entrance ways 42 at their lower ends to receive the carbon roll-holder presently to be described. At their upper ends said side bars terminate in socket portions 39 which receive the ends of the e);- tensions 43 of a frame piece 43, which frame piece provides a bearing for a guide roller presently to be described. The frame piece is preferably made of wire and is shaped like an inverted U, the extensions 43 forming the sides of the U and being fixed in the sockets 39 in any suitable manner. Cross arms 44 connect the sides or extensions 43 and are suitably secured thereto, said cross arms serving as braces to strengthen the supporting frame and ma'lre it rigid.

Before the wire forming the frame piece 43 is bent into shape it receives a guide roller or guide 45, the construction of which is best shown in Fig. 5. The guide roller proper is a hollow cylinder which is propieces 46, said hubs being suitably secured in the ends of the guide roller 4-5. lhe guide roller is adapted to turn freely on the frame piece 43 but is held from endvvisc motion by collars 47 abutting against the end of the hubs 46. Said collars 47 are secured to the frame piece by set screws 48.

The details of: the material carrying or roll-holder device are best shown in Fig. (3. The roll-holder proper 49 is preferably made solid to give it weight, for the reason that in the present construction gravity is de- 'ways 41, rack bars 55 (l i pended on to move the roll-l'iolder automatically and rewind the carbon paper or other material thereon, as will presently be described. he roll-holder is cyliinlrical and is formed with reduced end portions 19. Said roll-holder is mounted on a. shaft 50 and is adapted to turn Iwith said shaft ordinarily but may have a rotary motion independent. thereof by reason of a frictional connection with said shaft. The shaft at its ends is slightly tapered and carries pinions 51, said pinions being driven on to the lapered end portions of the shaft and being held in place by headed screws 52 which are received in tapped openings in the ends of the shaft, the heads of said screws being provided with flanges 52 which abut against. the outer heads of the pinions 51.

One end of the roll holder 45) is formed with a depression or socket 523 which receives a coiled friction s n-ing 54, said spring surrounding the shaft 50 and bearing at one end against the bottom of the depression 53 and at the other end against the inner face of the adjacent pinion 51. It will be seen that the pinions 51 are fixed to the shaft 50 so that they always turn with it and it will be understood that by reason of the frictional connection through the spring 54- between the roll-holder proper 4.) and one of the pinions 51, said roll-holder will normally turn with the shaft and pinions without any change in relationship among them. it will be understood, however, that ii the shaft and pinions are held from turning the rolLholdcr 49 may, nevertheless, be turned it suliicicnt power he applied to overcome the friction of the spring 54. shown in Fig. (3 the distance between the inner faces of the pinious 51 is slightly in excess of the length of the roll holder proper 45) so that said piuions in then'lselves will not prevent relative turning movement of the roll-lmldcr, the friction spring performing this function.

The heads of the screws are a laplcd to cooperate with the sii'lcs'of the guide ways or slot-ways 41 in the side bars 39 to guide the rolbholdcr up aml'down lengthwise of said slots, the llangcs 52 preventing cudwisc displacement of the r llholdcr. In order to cause turning movements of said roll-hol lcv during its excursions up and. down the slot- 1., 2 and T) to cotipe ate with thepinions of are provided. said rack bars extending lengthwise of said slots and being secured to the inner wall.- of the side bars 3%) at the rear sides of the slot-ways 4.1.

To insure the proper engagement of the teeth of the pinions teeth of the rack bars 55, a mechanical loading device is provided for receiving the roll holder and entering the roll-holder in place on the machine, or loading it. dcfore entering the roll-holder in place :1 rolled 5L with correspond ing ceases son to unwind or wind the sheet 56.

The loading device is illustrated in Figs. 1, 2, 7 and 9, comprising a rock-shaft 58 having bearingsin the bases of the side bars 39.

Adjacent the inner faces of the side bars 39, cradle pieces 59 are mounted on the rock shaft 58, said cradle pieces being provided with hubs 60 wh ch are pinned or otherwise suitably secured to the shaft. Each'cradle piece is provided with a toe or extension 6]: having a curved edge 62 which is a continua tion of the curved upper edge 63 of the body of the cradle piece. The shaft 58 extends outward through and beyond the right-hand side bar39 as shown most clearly in Fig. 9, which is a rear View. The extended partof said shaft receives a handle 64 which is provided with a hub portion 65, said hub being driven or otherwise suitably secured to the shaft 58. The hub 65 is provided with a depression 66 which receives a coiled restoring spring 67, one end of which engages the hub,-

the other end engaging the adjacent side bar 39. The spring 67 tends constantly to turn the shaft 58 and. the cradle pieces forward, and normally maintains the right: hand cradle piece in contact with a stop pin 68 projecting laterally inward from the lefthand side bar 39. If desired, the spring 67 may be dis ensed with and the loader operated entire y by hand.

Vihen it is desired to enter the roll-holder in place in the machine the handle 64 is pushed rearward, turning the loader to the position shown in Fig. 7 then the roll is placed on the loader with the reduced end portions- 49 engaging the curved edges 62-63. The roll holderis thus seated or cradled, as it were, on the loader, the handle whereof is then. released, enabling the spring (37 to turn the loader forward onits axis of rotation and causing the edges 63 to press the roll-holder forward. During the first iart of the forward motion of the rollholder, the heads of the screws 52 will pass through the mouths or entrances 42 of the guideways 41., and. the forward movement of the roll-holder will continue until the'heads of screws ccntact with the front walls into mesh with theiacks, 55ers appears from an inspection of Fig. 8. It willbe seen that the loading device or loader affords a simple and convenient means of entering'or feeding the roll-holder or material carrying device into-place'into the machine and insures that corresponding teeth of the rack bars 55 will be engaged by the associate pinions 51.

When the roll-holder is in'place, the free I end of the carbon paper 56 may be drawn upward at the front side of the roll-holder and over the top of the guide roller 45. Thence the carbon paper passes down over the front of an inclined chute ortable 69 (Figs. 1 and 2). The chute is fastened to and supported by rods 70 extending forward from the upper cross rod 44 and is also-fixed to an angled bracket 71 which extends forward from the left-hand side bar 39 and thence inward behind the chute, broadening out near its end to receive two securing screws 72 which enter theback of the chute. The side edge portions of the chute 69 are bent or inclined inward indicated at 69 over the top of the being inclined slightly forward as best shown in Fig. 2, so that when the carbon paper passes the lower free end of the chute, which terminates slightly above the platen, said carbon paper will pass downward behind the platen and in between said platen and the rear feed roller 24. The platen may now be turned in line' spacing direction to feed the carbon paper through the machine until it passes so far beyond the forward edge of the paper apron 29 that at the end of the automatic retracting movement presently to be described, the free end portion of the carbon paper will be between the platen and the forward end of the paper apron so that the carbon paper may be clamped by the paper apron ifs hereinafter explained.

When the carbon caper is led off the rollholder and is pulled upward and over the guide' roller :45, the roll-holder will, of course, be turned or rotated. Because of the engagement of the pinions 51 with the 1 straight rack bars the roll-holder as it rotates, will also move bodily upward, the piniens rotating and-traveling along the rack -bars 55,- nevertheless the roll-holder will continue to turn 'fll'ld fpermit further uninter rupted movement 0 the free end of the carbon paper because of the frictional device or spring 54:. The lengths of the slot-ways ti and lack-bars 55 are preferably proportioned to allow a length of carbon paper to be unwound movement of the roll-holder equal to the length or the longest bill sheet or work sheet which is intended to be written.

Cir

Supposing that the carbon paper 56 has been drawn forward past the paper apron as above explained and that the release key 28 be pushed rearward to move the feed rollers 23 and 24% away from the platen and release the carbon paper, then the roll-holder. 49 being weighty will promptly run downward in its slot-ways under the influence of gravity. As it runs or moves downward, the roll holder will be rotated through the pinions 51 and racks 55, thus rewinding the carbon paper. This rotation or turning of the rollholder and rewinding of the carbon paper will continue until the roll-holder reaches position of rest near the botton of the slot ays 41, where it may be arrested by contact with the edges 68 of the loader. It will be noted then that the loader may perform an additional function, serving as a closure for the lower ends of the slot-wuys -11 and as a stop to limit the downward run of the rollholder.

In order to prevent running up or excess movement of the transfer sheet or carbon paper during the rapid downward morement of the roll-holder, n'mans are provided lorrausing the paper apron 29 to automuh ically grip or clamp the free end of the cari bon paper when the roll holdcr reaches the end oi its downward travel. This automatic gripping or clamping means comprises an arm 73 lined to and depending from a sleeve 74 surrounding the rock shaft 2?. The arm T23 is provided with an open-mouthed slot-75 which receives the lateral pin as best shown in Fig. 4 A angular arm 76 is fixed lo the top of the sleeve Tel and extends rearward from said sleeve and then upward, being; formed at the rear of its upper end portion with an inclined or cam edge 77. This cam edge cooperates with the left-hand red need end 49" of the roll-holder so that when the roll-holder nears the end of its downward travel it contacts with the edge 7? and turns the gripping member (comprising the arm 70, sleeve 74- and arm Til) on the shaft 27, thereby rotating the lover iii-32 on the rod 1? and forcing the forward portion of the paper apron or gripping device toward the platen to clamp or grip the carbon paper movement around the platen. The operative positions of the grippingmember and mpel apron are illustrated in Fig. at.

it will be understood that an operation such as that described, beginning with the loading and ending with the downward run of the roll-holder, is only necessary when the during the upward bodily l l l roll-holder by the edges (ill on llio roll of carbon paper first lozni'cd or cni rcd in the machine. suming ihnt the (nametion has been gone through with as :ibrwc dcscribeiil, the mechanism. and the carbon pm per are now arranged to cooperate with the bill sheet or paper to be written on. its is well uinlcrstood the work ehccts commonly employed with ihis clas oli mechanism are in the liu'm cl" folded bill sheets, such us ihul illust 'aled in Fig. 1 and numbered '18. The bill sheet is entered into the machine by lb: 1 passing thejolds or lcnvcs Ibci'col one in front of and one behind the chute (il so that the bill straddles the chute and the fo d ol? said bill is brought into elurugemcnt with the right-hand edge ol the chute. Then the bill is slid dowmvnrd until its edge p; a luetwecn the roar :lecd roller 21! and the platen, said platen being then iurncd until. the bill has been advanced into posiiion lo receive the iii-st line of writing. is wcll undcrstoinh this operation rcsulls in inclos inn; lhc cnrlum paper between lhcr folds of the bill and said carbon pnpcv will be led forward lhrtmgb the .i'i'iochinc with the bill sheet. At the start ol the lccdi o l lhc can bon paper; the bodily upward nun mcul ol the roll holder will begin and .d roll holder will scpurni from thc cum cdgtc permitting the pap npron 2; to fall away from the platen to the 1 osiii m shown in Fig. ll.

The writing is done in the usual way, the usual inking ribbon (not shown) inking;- the outer l'old ot the bill and the inner lold thereof being printed lrom tho :H'bol] paper as is well understood.

\Vhen the writing on the bill has been completed said bill may be led forward out 01 the machine and then the release lcvrr 28 mi be hushed rearward to rch we the car bon paper or lruuslm' shoct. is soon as the carbon paper is rclcnscd. the rol hohh r ltl will run downward under the inllucucc of gravity, turning during its downward run lo wind up the carbon paper and food it baclo ward through the machine until said carbon paper is arrested by the clumping plate or paper apron 25 in position to begin the op- F eruiious l'or writing on u now or second bill sheet, and arrest its further backward teeilmg.

viously when the edge 77' operates in this. vay, the weight of the roll-holder will be applied to the paper apron through thereonnections between said paper apron and the edge 77 so that the clamping power or fric timi will be maintained constant. When the edge 77 is arranged in themanner last de scribed it will, of course, be necessary, in order to introduce the roll-holder into its force the upper arm 7?) forward on the rock shaft beyond its working position.

v by my holder There must therefore be suilicient yield or give in the connections between the arm 76 and the clamping plate or paper apron, or suficient resiliency in the arm 76, to permit of the for-cine forward of said arm. 76.

By the construction above described, it will be noted that the spring devi -es heretofore commonly employed to automatically retract or rewind the carbon popes? in this class of carbon roll 'mechsnism are dis penscd with, and the construction-is thereby simplified and rendered more certain in operation. Furthermore, it will be noted that the automatic clamping device or aper apron E29 advantageously replaces the rake mechanism heretofore made use of to pre; vent overrunning; or excess rewinding of the carbon paper. lit will further be seen that present invention 1' provide a rolldevice compjrising a roll holder pro er, a shaft extending through said rollholll or proper, pinicns 'fixed to said shaft at the ends of sale roll-holder proper and yielding connection between said r0ll-holder proper seid shaft; that said yielding connection is a frictional connection and comprises afriction spring which cooperates with said roll-holder proper and with said shaft; that said pinions are retained on said shaft and prevented from accidental displacement therefrom by screws'which are provided with beads that serve as guides for said roll-holdcr device when it is mounted in the machine; that combined with the rollically holder device or roll-holder is a loading device 6r loaderfor receiving said roll-holder outside the machine and introducing it into lace in the machineso thn' t-itiis automatbrought intofcooneration' with controlling meclianism,' saidicoi'itrolling mechcnism comprising a pair .of racks or rack "bars; that said loading (ii-W109) is pivotally mountedonthe machine and is movable by hand into position to receive the roll-holder;
