As usual in one Underwood typewriting machine, types 1 strike rearwardly through a ribbon 2 threaded through a viorui'oi 3) against the front side of a cylindrical plnten or roll l, which is mounted by an axle 5 in the ends 6 of a platen frame, i'he lndei' also compiling e peoer shell '2"a in rear of the platen. and formed upon its top with :1 rolled brim 8. The platen is turned either by a line-spacing end cen'icge-retui'ning lever 9, or by knobs 10 fixed upon the ends of the platen axle 5. Pressure rolls 11., 12 i-i'in w en the under side of the platen to feed the paper in line space direction. The platen f" in said llnderwood machine is mount ed upon e carriage 13 which irevcls upon in horizontal rail 14 for letter feeding; ears 15 depending {com the carriage to he -upon rail. 7

There ere shown three horizontal rolls or webs of e pes 16, '17, 18, in the reel: of the type-writinginechine, with their axes exi'ending reerwerdly sight angles to the carriage-rail 14, or to the direction of irnvel of carriage. From these rolls the webs are led upwardly to the right (to the left at 1), as indicated si 19, 20, 21, to ahorizontel guide on? 22 fixed upon the carriage, said her ex'lending rearwardly to the axes 23 of said paper rolls. it will be understood lmwevcr that ii; is not always necessary that ihe webs shall he in the form of rolls, so long as the means herein disclosed are employedfor guiding the Webs to the line-feeding sells on the cm'i'isge.

The Webs (of which either one 01- more may be used, es z'eqnii'ed) turn around over the of said nide 22, thence'rnn 1e ve'sely, or longisudinally of the "paper carliaise to second guide be? The latter "ds diagonally at an angle oi" degreesinc guide bar 2n; the apex of the angle being at the rear ends of the bars. The webs dip under the diagonal bar 24, and fold over the same to take a direction (considered edgewise) at right angles to their preceding direction, or parallel with the 2-2; and then they run over the rclled hrim and parallel c 8 on the paper shelf, and thence down between the plaien e and the feed rolls machine,

tom of the platen and up between the same and a knife 25 usuallyemployed for severing the webs after writing. If a web is not severed, it may pass rearwardly from the as indicated at 26, and drop over a horizontal guard 27 extending in the same direction as the carriage travel, located in rear of the guide bars 22, 24. There may be also employed simultaneously additional horizontal rolls 28, 29, in a row forming a tier above the row of rolls already described; and the

webs

30, 31 from the upper rolls may interleave the webs from the lower rolls, as seen at Fig. 1. In some cases the rolls 28, 29 may'consist of carbon paper, to

make copies on the

webs

20, 21 of theoriginal matter written on the web 19. Any suitable system of ink ribbons may be mounted on the carriage to run between the webs to write upon the under webs. The ribbon 2 writes upon the upper web 19; said ribbon 2 being usually wound on spools 32.

. It will be understood that the paper rolls may have other than horizontal axes, so long as their axes run at an angle to the direction of travel of the carriage, and so long as the webs led from the rolls fold over a diagonal bar to alter the direction of the travel of the web to run to the paper feeding rolls of the carriage.

In the present instance the roll axles are detachably hung in open vertical slots 33 out in the top of a pair of horizontal supporting bars 34 connected by cross bars 35, the latter having legs 36 to rest upon a table.

Preferably a pair of perforated ears 37 are. bent forwardly from the forward bar 34, to be inserted between the usual rubber feet 38 and the bosses 39 formed on the bottom of the typewriter framework 46; said ears secured by the same screws 41 which usually secure the rubber feet 38. From the bars 34 rise standards 42 to support-the rolls 28, 29, whose axles 43 rest detachably mounted in slots 44 in the tops of said standards. lhe guard 27 is bent down at its ends to form standards 45, secured to the end bars 35 of the roll frame.

The web-controlling guides 22, 24 are preferably formed of a single length of wire bent at 46 to give the required angle. At their forward ends the bars are secured in collars 47 adjustable along a rod 48 and secured thereon by screws 49. The rod 48 is carried in arms 50, the latter supported by a rod 51 fixed in brackets 52, the latter fixed by screws 53 uponth'e carriage 13.

Side guides or gages 54 for the edges of the web or webs may be adjusted along the guide bar 22 and secured in any suitable way.-

It will be seen that all the work of unwinding the webs from'the rolls occurs during the return of the paper carriage to begin a new line. The webs hang loosely from the bar 22 during the writing of the 'line, and offer no impediment to the operation of the carriage.

Many variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.

Having thus described my invention, I. claim: 1

The combination with a letter-feeding paper carriage having line-feeding devices, of a roll or web of paper mounted upon a stationary support, its axis at about a right angle to the travel of the carriage, a guide upon the carriage over which the web from said roll is led, said guide being about paralv lel with the axis of the roll, and a diagonal guide over which the, web folds to run toward said line-feeding devices, said web guides formed of a single rod bent to give the required direction to the guides; said bent rod being secured in collars which are adjustable along a support provided upon the carriage.

2. The combination with a letter-feeding paper carriage having line-feeding devices, of aroll or web of paper mounted upon a stationary support, its axis at about a right angle to the travel of the carriage, a guide upon said roll is led, said guide being about parallel with the axis of the roll, and a diagonal guide over which the web folds to run toward said line-feeding devices; said web guides being adjustable along the carriage to position the web longitudinally of the platen.

3.' The combination with a letter-feeding paper carriage having line-feeding devices, of a plurality of paper rolls orwebs mounted upon stationary supports, their axes extending horizontally and rearwardly, a horizontal guide webs are led, said guide extending rearwardly, and a horizontal diagonal guide over which the webs fold to run toward the line-feeding devices of the machine; the diagonal guide adjustable along the carriage to position the webs longitudinally of the platen.

4. The combination with a letter-feeding paper carriage provided with line-feeding devices and having a guide, of a diagonal guide, and a paper web running over the first guide and folded around the diagonal guide and running thence to the line-feeding devices; the diagonal guide adjustable along the carriage. w

'7. A letter-feeding paper carriage having line-feeding devices and provided with Web guides projecting therefrom, one at an acute angle to the other; one guide in position to receive a Web traveling in one direc* tion, and the second guide to cause the Web to make a fold to travel toward said paperfeeding devices; the second guide being adjustable along the carriage.

8. A letter-feeding paper carriage hav= ing line-feeding devices and provided with Web guides projecting therefrom, one at an acute angle to the other; one guide in posi tion to receive a Web traveling in one direction, and the second guide to cause the web to make :1 fold to travel toward said paperfeeding devices; the second guide being adjustable along the carriage, and a guide pro- .vided upon one of said guides for the side edge of the Web.
