TYPEWRITING MACHINE.

Application led November 2B, 1923. Serial No. 677,863.

To ZZ 207mm it may concern:

Be it known that I, MAX R. URBAN, a citizen of the United 'Sta-tes, residing in Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Typewriting Machines, of which the following is a speciication.

This invention relates to typewriting machines, and more articularly to work-websupplying and car on-carrying means therefor. More artieularl it relates to typewriting mac ines of tie continuous billing class.

ln the continuous billing machine, as illustrated for example, in the patent to Wernery and Smith, No. 1,132,055, provision is ordinarily made of a long carriage-extension supported in part upon a rear eX- tension of the machine frame, andhaving a track upon which a carbon-carrier is reciprocable toward and from the revoluble platen of the machine. The work-webs have heretofore been introduced into the machine at the rear of the carriage-extension from stationary web-carrying rolls or other suitable web-supplying means located to the rear of the carriage-extension and generally at a substantial distance below it.

This arrangement of the web-.supplying means is open to several objections. lin order to make the web-supplying means accessible for the replenishment of the web and for other purposes, it was necessary that considerable space be provided at the back of the desk on which the machine was supported, and this was a drawback in crowded offices. The web-supplying means was not visible to the operator moreover, and hence one of the webs was apt to become exhausted without the operator-s knowing about it. This would result in the writing of one less copy than intended until the fact vthat one of the webs had become exhausted was discovered, when it would be necessary, of course, to rewrite the form or,

forms of which an insuiiicient number of copies had been made. Then, too, a stretch of slack -had yto he provided in each web between the stationary web-supplying means and the movable carriage-extension billing machine 1s supported to accommodate the relative movement of these parts, and these slack stretches of the webs, especially if separate narrow webs were employed, were apt to become disarranged, or tangled by the wind.

In accordance with the present invention, all of the above-mentioned difficulties are overcome by the provision of a websupplying frame mounted for movement from side to side with the carriageu This frame is preferably mounted on the usual carriage-extension above the carbon-carrier. `Web rolls may be mounted on the frame and are preferably arranged in a horizontal row, so that all are visible to the operator seated at the machine and are readily accessible for web replenishment.v When the web upon one of the rolls is exhausted, the operator can .observe the fact at once and can easily insert a fresh web-supply. The mounting of the web-supplying rolls to travel with the carriage eliminates the need of the webs as the carriage travels from side to side. A substantial economy of oltice space may be effected also, due to the fact that the desk upon which the continuous can be placed back to back with another desk, or can be placed against the wall.

The webs areV directed by suitable guides from their supply rolls to the rear .of the carriage-extension, and are thence led forward between the earbons of a carboncarrier reoiprocable toward and from the platen. The carbon-carrier may include the usual stepped frame, but the steps of the trame, according to one method ofpracticing the invention, are not used. Brackets are detachably connected to the carboncarrier frame and bear carbon-carrying rolls, each of which rolls is provided with carbon for active use and also with a considerable reserve supply. Provision is made of means for holding the carbon-carrying rolls against rotation in the ordinary operation of the machine, but such means may be released when it is desired to replace a- Uli Vus

wornout stretch of active carbons with a fresh stretch.

It is a feature of the invention ,that the supports for the work-web-supplying rolls are adjustable toward and from each other to accommodate diierent lengths of webrolls between them, and are also adjustable together to locate the web in line with different selected fields of the platen. The carbon-roll-supporting brackets,too, are adjustable toward and from each other to accommodate carbon-rolls of different lengths in accordance with the width of the work-webs, and are adjustable together to locate the carbons in line with different selected fields of the platen, the adjustments of the carbonroll-supporting brackets being made to correspond to the adjustment of the supports for the work-web-supplying rolls.

In accordance with one feature of the invention, the web-supply .frame is detachably mounted upon the carriage-extension, and the carbon-roll-supporting brackets are detachably mounted on the carbon-carrier. The carbon-carrier frame has provision. as usual, for the attachment of carbon-holding blades.

4It will be seen, therefore, that the machine may be quickly converted for doing fan fold work in the previously known manner.

The carbon-carrier mav be converted for.

fan-foldwork independently of the removal of the web-supply frame, and, conversely, the web-supply frame may be removed independently of the conversion of the carboncarrier.

Provision is made kfor changing the workweb in the machine at will, when a diiferent style or width is desired. The supports in which the ends of the web-supplying rolls are journaled are connected to each other to from a rigid truss, which is held to the remainder of the web-supply frame by its own weight and the weight of therolls, and therefore may be removed at will from the frame. The carbon-carrier is also detachably mounted on the carbon-carrier base. When it is desired to substitute in the machine a web of a different width, or different in some other characteristic, from the web in the machine, the carbon-carrier and the web-supplying rolls may be removed from the machine together without disturbing the interleaved relation of the work-webs and carbons, and a truss bearing paper-webs of the desired width, together with a carbon-carrier having carbons of the desired width interleaved with said webs, may be substituted.

Other features and advantages will hereL inafter appear,

In the accompanying drawings,

Figure 1 is a sectional side elevation on the line 1--1 of Figure 4, showing a continuous billing machine having the present invention applied thereto.

Figure 2 is a detail lon itudinal vertical section on the line 2-2 o Figure 7, showing an end of the web-supporting truss, and its connection to an end member of the web supply frame.

Figure 3 is a horizontal section on the line 3-3 of Figure 4, showing an end of the web-supporting truss.

Figure 4 is a transverse vertical section on the line 4.--4 of'Figure 1, looking toward (not shown) are depressed to swing types 10 upwardly and rearwardly to print against the front of a revoluble platen 11,l

journaled at its ends by a platen-axle 12 in a swing-frame 13 mounted on the .traveling carriage 14 of the machine. The carriage 14 is movable from side' to side in the usual manner upon a front rail (not shown) and a rear' rail 15 supported by the machine frame 16. A rear carriage-extension 17, comprising brackets 18, transverse rods 19 and 20 and longitudinal rods 21, is mounted for movement with the carriage 14being sup rted at the. rear upon a rail 22 mounted at t e rear of an, extension 23 of the machine frame 16. The carriage-extension 17 has rails 24 upon which the base 25 of a carbon-carrier 26 is mounted for movement toward and from the platen 11. At line-spacing, the carbon-carrier 26 advances toward the platen with the workwebs A and carbons B. When the typing of a stretch of webs is completed, the swing-frame 13 is displaced to raise the platen 11 and thereby to permit straightening of the-carbons B; the work-webs A are drawn forward to a gage 27; and the carbon-carrier 26 is thrust to the rear to withdraw the carbons from the completed section of web A. The platen 11 is then restored to normal position and the completed web-section is severed by means of a knife 28 located at the front of the platen. As thus far described, the machine is like the Wernery and Smith machine referred to above.

In' accordance with the present invention, provision is made of a work-web-supply frame, which is mounted on the carriageextension 17 for movement therewith from side to side of the machine. This frame consists principally of upright end members 29 and 30, mounted, respectively, at the front and rear of the carriage-extension 17 and a connecting roll-supporting truss 31. The end members 29 and 30 are in the form of inverted Us, the forward member 29 consisting of vertical legs 32 and a horizontal body 33, and the rear member 3() consisting of vertical legs 34 and a horizontal body 35.

The -lower ends of the legs of the end members 29 and 30 are detachably connected to the carriage-extension 17, the arrangement being such that the web-supply-frame may be quickly removed from the machine. Each leg 32 of the front upright. frame member has its lower end curved to partially embrace the front transverse rod 19 of the carriage-extension 17, and is provided with a complementary clamping jaw 36, which may be drawn forcibly toward the leg 32 by turning a knurled headed screw 37, threaded into the leg 32, to cause the jaw to co-operate with the leg to clamp the leg firmly in upright position upon the rod. Each leg 34 of the rear end member has a -pin 38 projecting from it. which is received in a clamping plate 39 to correctly locate the latter. A knurled headed screw 40 passes through the 'clamping plate between the transverse rod .20 and another-transverse rod 41 commonlv provided at the rear of the carriageextension 17 for web-guiding purposes, and is threaded into the leg 34 of the rear end member 30. The screw 40 may be turned to draw the clamping plate 39 toward the leg of the end member to clamp the end member securely in uprightposition.

The weblrollsupporting truss 31 consists chiedy ot' a left web-roll-bearing side member. 42 having inturned ends 43 and 44 and a right web-roll-bearing side-member 45 having inturned ends 46 and 47. The rear inturned ends 44 and 47 of the side members 42 and 45 co-operate to form the rear end of the truss 31. and the forward inturned ends 43 and 46m-'operate to form the forward end of the truss. 'lihe inturned endsv of the side members are connected to each other, with provision for widthwise adjustment of the truss to enable the truss to be used with web-rolls of different lengths. A headed screw 48 passes through an elongated slot 49 in the inturned end 44, and isl threaded into the inturned end 47, and a similar screw 50 is received in an elongated slot 5l in the inturned end 47. and is threaded into the inturned end 44. One or both of these screws 48 and 50 may be tightened to secure the end members 44. and 47 against relative movement. The forward inturned end members 43 and 46 are similarly connected to each other by screws 52 and 53. llach of the forward inturned ends 43 and 46 is provided with a hook 54 to extend forwardly and downwardly to interit with one of a series of notches 55 in the horizontal body-portion of the forward frame end member 29, and each of the rear inturned ends 44 and 47 is provided with a similar hook 54 to extend rearwardly and Idown` wardly to interfit with one of a series of notches 55 1n the body-portion 35 of the rear frame end member 30. A considerable number of these notches 55 is provided, so

that various widthwise adjustments of the truss 31 may be accommodated, and so that the truss may be positioned in line with various fields of the platen.

The side members 42 and 45 o-f the truss 31 have downwardly and rearwardly extending slots 56 in their uppersides, the lower ends of which form bearings for shafts 57 of the work-web-supplying rolls 58. One of these web-supplying rolls 58, as shown in Figure 6, consists of a spool 59 of web, wound on a hollow core 60 which is 'placed upon a core member 61 mounted on the ,roll-shaft 57. Arms 62 extend downwardly from the side members 42 and 45 between the ends thereof, and have downwardly and rearwardly directed slots 63, which receive and form bearings for the 'ends of a web-guiding roll 64. Similar arms extend downwardly from the side members 42 and 45 adjacent their rear ends, and have downwardly and forwardly directed slots 66, which receive and form bearings for a web-guiding roll 67. The

work-webs are unwound from the rolls 58 by rotation thereof in a counterclockwise'direction, and are led to the rear over the guide-roll 64, thence around the guideroll 67 and forward through the carboncarrier 26 to the platen 11.

The carbon-carrier 26 reciprocates toward and from the platen in the usual manner, but embodies in its construction several features of novelty. The usual carbon-carrying blades are not used although the usual provision is made for their attachment, but

instead there are attached to the carboncarrler two co-operating carbon-roll-supporting brackets 68. Each bracket 68 comprises a transversely-extending portion 69 by which it is attached to the carbon-carrier frame 70, a rearwardly-extending portion 71 for bearing thecarbon-rolls 72, and an inturned web-guiding finger 7 3 for holding the uppermost work-web A down to the carbon-carrier. y. The transversely-extending portions 69 of the brackets 68'have' elongated slots 74ytl1erein, and through each ot these slots therepasses'a screw 75 that is threaded into. the rear ofthe carbon-carrier frame for securing the bracket thereto. lThe brackets 68 mav be adjusted toward and from each other by reason of the screwand-slot mounting to vary theJ distance between the bearing portions 71 of the brackets to provide for carbons of `different widths v corresponding to the different widths of work-webs used. rllhe rearwardly-extend ing bearing portions 71 of the brackets 68' have open-ended slots 76 which form bearl nut 82draws the shaft 77 lengthwise, causing ythe flange 78 to bear against the end 79 of therarbon-paper spool and force the other end of carbon-spool 72 against the washer 81. This. pressure secures the carbon-spool 72 against rotation relatively tothe washer 81, and the pressure of the washer against the bracket 68 prevents rotation of the washer, so that the carbon cannot be unrolled whenl the nut I82 is turned up tight. tions 71 of the brackets 68 are upwardly inclined, so that the carbon-rolls 72 are arranged conveniently to have the work-webs vA led forward between them.. Whena stretch of carbon is used up. the nuts 82 are loosened and the forward ends of the carbons are held stationary while the carboncarrier is retracted, to unwind a fresh formlength of carbon. The used up stretch of carbon is then severed with a ytyped workweb section and the nuts 82 are tightened to again secure the carbon against unwinding.

The carbon-carrier frame 70 to which the bracketsV 68 are attached is detachably mounted on the base 25 in the manner disclosed in the patent to Benjamin P. Fortin, No. 1,237,319, granted August 21, 1917. The carbon-carrier frame 7 0 with its carbonrolls 72 and the web-supporting truss 31 with the work-web rolls 58 may be removed from the machine together therefore. without disturbing the interleaved relation of the carbons B and work-webs A, and may be replaced bya web-supporting truss and a carbon-carrier having webs of a different style or width interleaved with carbons of an appropriate width. Unless the workwebs A are quite narrow, the weight of the web-supplying rolls 58 will be-considerable, and their inertia is apt to cause the Work to slip relatively to the platen 11 -at line-spacing andso to cause irregular ffline-spacing. Provision is made of a clamp 83. therefore, for drawing the work-web A forward with the carbon-carrier 26, preparatory to typing, to create a slack in the work-web atv the rear of the carbon-carrier, so that the rotation of the web-rolls 58 at line-spacing will bel unnecessary. This clamp may be like the one disclosed in the patent to Smith, No. 1,364,819, granted January 4, 1921. It comprises a stationary lower jaw 84 on the car- The rearwardly-extending por-v bon-carrier frame to underlie the workwebs A and carbons B and a. swinging upper jaw 85 extending above the work-webs and carbons and pivoted :1t-86 on the carbon-carrier frame .70. vA spring 87 normally draws the swinging jaw 85 down to effective position, and a bell-crank 88, pivoted on the carbon-carrier handle 89, may be moved by a clamp handle 90 slidingly mounted on the carbon-carrier handle 89 to render the swinging jaw 85 ineffective. The drawing forward of the carbon-carrier 26, while the clamp 83 is effective, draws the web A from the web-rolls 58 around the guide-roll 67. As the carbon-carrier 26 .again moves to the rear, a slack is formed between the guide-roll 67 and the carboncarrier', which is drawn upon at the subsequent line-feeding of the work. This slack is not permitted to fall at random where it may catch upon stationary parts of the machine or other objects, as it travels from side to side with the carriage, but is supported upon the movable carriage-extension 17, the longitudinal rods 21 of the carriageextension forming a table or frame for supporting the slack..

Variations may be resorted to within the scope of the invention, and portions ofthe im rovements may be used without others.
