TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented Sept. 3, 191$.

Original application filed January 12, 1916, Serial No. 71,606. Divided and this application filed June 19, 1917. Seria1No.175 ,578.

To all whom it may concern:

Be it known that I, BENJAMIN P. Fon'rIN, a citizen of the United States, residing in Hartford, in the county of Hartford and State of'Connecticut, have invented certain new and useful Improvements in TypelVriting Machines, of which the following is a specification.

This invention relates to typewriting machines and more particularlyto means for accurately guiding the sheets while in the machine.

This invention is an improvement on a machine of the type shown and described in the patent to W'ernery and Smith, 1,132,055, dated March 16, 1915, in which the fanfold Web advances over an auxiliary carriage,

and then over a carbon-retracting carriage,

where the plies of the webare interleaved with carbon sheets, the latter being carried by the carbon-retracting carriage. The web advances thence over a paper table and around the platen, andthen to a paper shelf at the delivery side of the platen.

A feature of this invention is the provision ofmeans whereby the sheets may be accurately gaged and guided during the Q11? tire travel through the machine, particu, larly at critical points in said travel.

The auxiliary paper table at the intake side of the machine is provided with a pair of upstanding fingers 'or side-edge gages, between which the leading end of the web advances.

To guide the web proper into register with the carbon sheets, the carbon-retracting carriage is provided with guides which engage the side edges of the folded web just before the web is interleaved with the carbon sheets. a

After a portion of the web has been writ ten upon, the platen is lifted, to straighten out the webs to permit the retraction of the carbons. The web sheets are then pulled forwardly by hand until the leading edges thereof meet a gage extending up from the paper shelf at the delivery side of the machine.- This gage determines the location of the bottom edge of the written form, which may thereupon be severed from the web by means of a knife.

To aid the operator in accurately alining the bottom edge of the written form with the knife, a gage is provided upon the auxiliary paper shelf. This gage is arranged to be engaged by the side edge of the paper, before the written form is severed from the web.

hen the carbon sheets are relieved from pressure by the shifting of the platen, the 60 carbon carriage is moved rearwardly to I bring the interleaved carbon sheets thereon into cooperation with a fresh portion of the web. During this movement, the guides ar ranged thereon, jog the web into proper superposed relation with the :arbon sheets.

Another feature of this invention is the provision of the novel arrangement and construction of these various gages, whereby they may be economically manufactured and readily attached to the machine, and so that adjustment may be made for the purpose of permitting forms of various dimensions to be used.

Another feature is the provision of one of the guides at the introductory side of the machine, with means whereby it may also be used to grip the web and prevent the same from falling off the machine. This combined guide and gripper is adjustable to accommodate webs of various widths.

This application is. arlivision of my copending application, Serial No. 71,606, filed January 12, 1916 (now Patent No. 1,237,319, dated August 21, 1917.).

Other features and advantages will hereafter appear.

web before the same is cut.

- to do so.

Referring to the drawings, the platen 10 has an axle 11 which is journaled in a frame having end pieces or arms 12 fast to a rockshaft 13. The shaft 13 is journaled in the end plates 1 1 of the platen carriage. The frame for which the shaft 13 serves as a pivot, is normally held in Fig. 1 position, with the platen down against the usual feed rolls 15 and 16. It is swung from its normal. or printing position, as shown in the patent to lVernery and Smith, N 0. 1,132,055, by means of an arm or handle 17, which latter is also fast to the shaft 13. For looking the platen frame in printing position, the handle 17 carries a pin 18 adapted to be engaged by a hook 19 pivotally mounted on a bracket 20 on the left-hand end plate 1 1 of the platen carriage. A spring 21 engages the hook and the bracket to hold the hook in platen locking position, and to return the hook to such position when free The nose of the hook is shaped at 22 to permit the pin 18 to cam it backward until the pin. can pass under the nose, thereby making the locking operation automatic when the platen frame is swung down to normal position. A tooth 23 on the hook may serve to determine the return throw, and normal position of the platen, in con junction with a pin or stop 24 on the righthand end carriage piece 141, against which the arm 12 strikes when the platen is thrown 'mesh with gears 30 and 31.

down.

To effect the line-space feed or rotation of the platen, there are provided the usual hand wheel 25 and ratchet wheel 26, both fast to a short shaft 27, mounted to rotate in the left-hand end piece 1 1 of the carriage. In printing position, the shaft, 27 is concentric with the platen shaft 11. The ratchet 26 is actuated by a pawl 28 on a slide 29 which may be operated, as in Underwood typewriting machines, by a linespace lever (not shown). A spring pawl (not shownl holds the ratchet wheel and platen against accidental displacement.

The driving connection between the shaft 27. whose axis doe-snot shift, and the platen axle 11, which swings from one to another position, consists of gears 30, 31 and 32. The gear 30 is fast to the shaft 27; the gear 31 is fast to the platen shaft 11, and is of the same size and number of teeth as gear 30; and the gear 32 is loose on the shaft 13 around which the platen swings, and has a face of sufficient width simultaneously to p A driving con nection between the shaft 27 and the'platen is thus maintained.

In the patent to Wernery and Smith, above referred to, it is shown that in the operation of removing a printed length of the web, and in readjusting the web for printing the next length, the platen is swung up from printing position to a position away from the feed rolls, so that the. web no longer wraps around the platen, but may be moved freely in substantially a straight line from the back to the front of the machine. lVhen the platen is in this position, the carbon sheets between the plies or folds of the section of the web to be removed, are drawn back into the length or section of web next to be printed; and, after withdrawing a length of the web, the platen is returned to its normal position against the feed rolls.

The web is preferably in a single piece, fan-folded longitudinally, to provide for several copies when carbon sheets are interleaved with the folds. It may also be in crosswise fan-folded condition before being fed into the machine to permit of compactness and convenience in handling, or it may be fed from a roll. It is fed into the machine over a bar 33 at the rear of a table 3 1, shown as formed of tubing. The rear bar is connected with a front bar 35 by side bars 36. The front bar 35 is mounted in ears 39 on brackets 40 on the platen carriage. From the side rails 36 depend arms 43 carrying rolls 44awhich ride and support the table on a rail 415, connected to the main frame of the machine.

The web is led-across the table and ove1 the front end thereof behind the platen, whence it is passed down between the platen and the pressure rolls, and thence up across the printing line at the type T, and onto a 105 paper shelf 18 forming part of the swinging platen frame carried by the arms 12. To the shelf 48 is secured a gage in the form of a bar 19, having adjustably mounted thereon a gage piece 50. The latter is a bent 110 metal strip having openings through which the bar 19 passes, and having an offset portion against which the web can be drawn in measuring the length of the sheet to be cut from the web at the cutter 51. The cuttei. 115 is shown as a blade fast to a sleeve 52 which is loose on the shaft 13. A finger piece 53, also fast to the sleeve 52, is used to swing the cutter against the web when a measured length of the latter is to be removed. A 120 snriug 54 holds the cutter in normal position away from the web, and returns the cutter to that position when'the finger piece is released.

and 5) for the side edge of the web. The guide 56 has a hole through it to receive any one of several screws 58, positioned at intervals along the brace 55, according to the before it is cut.

width of web employed; and a thumb nut 59 threads onto the screws for detachably securing the guide in selected position. Ears 60 on the guide, by engagement with the edge of the brace, prevent the guide from being tipped out of correct posltion, and aid in the proper setting of the guide.

It has been stated that the web is folded longitudinally so that a pluralityrof copies may be made at a time by the use of carbon sheets. These carbon sheets, as above stated, are drawn back from the written portion of the web, into the length thereof next to be written, at the time the web is relea ed, and For permitting forward line-space feed of the carbon with the web, and for withdrawing the carbon sheets from the written to the next unwritten section of the web, there is provided a carriage. 61 to which the rear ends of the carbon sheets are attached. This carriage, (see Fig. 1) consists of a rectangular plate 66, having grooved rollers 64 which ride on rails 65 attached by screws to the tops of the side bars 36 of the table.

On the carriage 61, at each side thereof, is a stepped block 741. Fingers or clips 75, to each of which one carbon sheet may be attached, are securedto the steps76 of the blocks 74. The fingers are staggered; alternate fingers being secured'to the same side of the carriage, so that the fingers may lie in the oppositely directed fan-folds of the web. The steps ''76 space the several folds ofthe web sothat the fingers which hold the carbon sheets may not bind the web. The web, therefore, 'as soon as it reaches the carriage 61 becomes interleaved with the carbon sheets, the rear edges of which are held and the front edges of which are free,except that they areclamped be tween the folds ofthe web atthe platen by the pressure rolls 15and16. Releaseof this pressure, on lifting the platen, permits resheets,'relatively to the web;' and a handle 79-011 Lthe plate66 serves as a means for throwing back the carriage 61. A suitable step may be provided for stopping the carriage at the proper throw of the same.

Side. gages or guides for the web, in its passage across the table, are provided. One set of these is carried by the carbon holding plate 66, and comprises L shaped members 91-, the uprights 95 of which form the web guiding surfaces. These L shaped members are carried by and are preferably integral with strips or plates 96, slotted at 97 for the passage therethrough of thumb screws 98, which are threaded into the backs of the stepped blocks 74-. The screws 98 have shoulders 99 so that, by turning the screws in or out, the plates 96 may be clamped in set position, or may be released to he slid on the blocks 7% to any setting according to the width of the web. Flanges 100 on the blocks support the lower edges of the plates 96 to maintain the guide pieces 95 in vertical position. The plates 96 also have offsets 101 at their ends which by engagement with the sides of the blocks 74, prevent the plates 96 from being thrown inward against the screws 98 in such manner as to injure the latter.

Another set of lateral guides or gages for the web is found on a bar 102 rigidly sup ported by arms 103 from the rear bar 33 of the table. These guides comprise upright plates 104 and 105, each fast to a sleeve 106 slidable along the bar 102, (see Fig. 2). The bar 102, which is shown as a tube, is perforated at107 at intervals therealong to receive locking pins 108 which are shiftable in and out of the sleeves 106, and which, by projecting into the bar 102, hold the guides in place. Leaf springs 109 embrace the sleeves 106, and each has one end fixedly secured to the sleeve by a screw 110. The springs are slotted circumferentially thereof at 111 for the passage therethrough of headed screws 112 carried by the sleeves. The heads of the screws 112 hold the underlying ends of the springs to the sleeves, but not tightly enough to prevent free movement of the free ends of the springs circumferentially of the sleeve within the limits defined position on each return by the slots 111. The pins 108 also pass be turned down against the web to hold the web from slipping or being displaced when the carbons are belng interleaved, or whenever the web ISIQlGElSGd from the platen and is not held by hand. This clamp consists of a finger 113" horizontally offset from the guide 105. The left-hand sleeve106 is not only slidable along the bar 102, but may be turned thereon to bring the finger 113 to theweb. The :tront of the bar 102, at the left-hand side Of the table, also perforated at points 114:, so that when the finger 113 is swung to web-engaging position it may be looked in such position by entry of the pin 108 in whichever of the holes 114 accords to the set position of the guide along the bar.

It will be seen that the guides 104 and 105 at the introductory side of the machine, the guides 95 on the carbon-retracting carriage 61, and the guide 57 and gage 50 at the delivery sideof the machine, jointly aid in properly guiding the Web through the machine.

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