Ta a/ZZ whom/t may concern.-

Beit known that we, EDWARD B. HEss, ofthe Machines, of which the following is a specification.

to lThis invention relates to devices for feeding, guiding,controlling, and delivering paper sheets, cards, or envelops ordinarily used in writing-machines to the platen and coacting parts. Its purpose is to control the paper accurately and efficiently at all stages of its passage to and around theplaten and to provide for the ready and accurate use of mul-y dially of the platen to permit the passage betiple sheets of paper or cards.

As will be hereinafter apparent, the invenzo tion is applicable to various styles of machines, even to understroke machines, without substantial modification in the principles of construction and mode of operation. It has, however, been shown as applied to a front-stroke or-visible-writing machine.

We employ an `endless-band paper-feeder so arranged that it will travel in contact with the surface of the cylindrical rotatable platen at a side of the platen where the printing 3o does not occur. It is preferably a unitary band or structnreand is of such width as to contact or coperate with both the central and end portions of the platen and is preferably of'a width equal or substantially equal tothe greatest width of sheet the machine is adapted to receive. Cards or envelops or wide sheets may, therefore, be fed without adjustment or change of any kind and willbe eiliciently held and fed or directed around the 4o platen. It may be feasible to divide such an endless carrier longitudinally into two or more parts and yet have them behave in the desired manner. It is believed, ho\vever,\that the best results are obtainable when the carrier is continuous transversely. Such a carrier should be of nonelastic material to obtain the best results, although the material may, perhaps, be more or less elastic and the carrier operate satisfactorily under proper 5o conditions. In Iorder to insure a certain and platen. `mounted and arranged with reference to the platen that when no paper is being fed the carrier bears upon the surface of the platen uniform feed, particularly where multiple sheets are fed to the machine, we provide that the endless carrier shall be driven positively, and it is best that when so driven it should have the same surface speed as the Such an endless carrier being so and the platen and carrier both being po'si- 6o tively driven at the same surface speed dur- .ing the feedingroperation, it follows that 'the sheet or sheets inserted between them will he carried around the platen with accuracy and with a minimum disturbance of the relation of the sheets where multiple sheets are fed. The carrier should be capable of yielding ratween the two members of multiple sheets of such thickness as may be desired, and 'it is 7o very much preferred that this capacity of the carrier should depend upon the parts upon which it run-s and not upon its own elasticity.

An organization such as suggested comprising an endless-band carrier of non-elastic material and positively driven to run inthe same direction as the surface of the platen at the same surface speed and in contacttherewith involves a principle which, so far as is known, is entirely novel in this art. 8o

While, as stated, the best results are obtainable by employing a unitary endless carrier of such width as to contact and coperate at the same time with the central and end or lateral .portions of the platen, some of the advantages of this invention maybe obtained by employing feed devices comprising two or more narrow endless bands arranged with reference to the platen as in the Well-known Remington understroke machine or asshown 9o in the patent ofSpiro, No. 463,464, making the bands, however, of non-elastic material and driving them positively at`.the same surface speed as that of the platen.

In connection with an endless carrier of the character indicatedguides or delivery members are employed which, in coaction with the platen, receive. the cards or sheets from the endless carrier and while properly holding them during the act of printing deliver roo them from the platen. These guides or delivery devices preferably consist of endless bands, which, as herein shown, are frictionally driven from the platen, and they are so mounted and disposed as to be capable of adproperly guide the greatest 'thickness of sheets or cards that maybe delivered to them by l the endless carrier. If they are endless bands, they may be elastic or non-elastic, and in the latter event their radial movement could be derived from the parts on which they are mounted.

So far as is known endless-band guides cooperating with that side or face of the platen where the printing occurs and adjustable longitudinally of the platen are new. Preferably in conjunction with them the endlessband feeder or carrier coacting with the olf surface or side of the platen is employed, the conjoint use of these two organizations giving in a writing-machine ideal conditions and an inexpensive and simple construction.

In the machine herein illustrated and specifically described the feeding devices or endless carrier are located in rear (having reference to the line of travel of the paper) of the printing-line, and hence may coact with any portion of the platen. The subsidiary devices, which have been termed guides, and which may also be endless bands, and which receive the sheet from the carrier or feed devices, may lie wholly beyond the printingline oracross-t'- e., on both sides of-the print ing-line. These devices, coacting, as they should, with the printing-face of the platen, should be adjustable longitudinally of the platen to adapt them to sheets or cards of different width.

In the accompanying drawings, Figure lis a plan View, partly broken away, transversely through the central portion; Fig. 2, a front elevation; Fig. 3, an elevation of the righthand end of the machine with the carriagecarryingrails in section; Fig. L1, asimilarview of the left-hand end of the machine; Fig. 5, a detail view indicating the roller-bearing of the carriage upon the carrying-rails; Fig. 6, a detail transverse section showing only the platen, endless carrier, guides, and associated parts; Fig. 7, a like view showing the same parts in a different position; Fig. 8, a detail View showing one of the channel-arms in which the lower rolls of the endless guides are mounted; Fig. 9, a front elevation, and Fig. 10 a transverse section merely indicating an organization in which in lieu of endless-band guides ordinary clamping-fingers are employed.

The carriage is composed ot' end plates a a, tied together by bars. The carriage-rails b l) are to be supported in any appropriate way in the frame of the machine. They are located, respectively, at the lower front and rear top parts of the carriage and are formed with longitudinal grooves, preferably V- shaped, in which run antifriction-balls c, spaced by a perforated plate d, Fig. 5, and embraced above by corresponding grooved rails or bars c e, forming part of the carriage. This structure affords a practical and very efficient mode of mounting the carriage. It has been deemed unnecessary to indicate a frame and carriage actuating devices. They, as well as the type-bar and other usual mechanism of a writing-machine, may, except as herein stated, be of any suitable character.

The platen f, of any usual character, has upon its shaft the usual hand-wheel. At one side of the platento the rear, as here illustrated-is mounted a pulley g, turning in bearings in the end plates a a and substantially equal in length to the platen. Around this elongated pulley or roller passes an endless band h, as wide, substantially, as the platen is long. Below the platen and somewhat in front of a vertical plane passing,r through its axis is a roller or pulley fi, preferably of somewhat less diameter than g, but of equal length. The pulley t' is supported in bearings in arms 7c, preferably curved somewhat to conform to the curve of the platen and pivoted in rear of the platen adjacent the ends of the roll g in brackets m, mounted on the end plates of the frame. The arms have projections extending upwardly and forwardly in the special construction shown from their pivots and have pivoted to their ends links n, which incline upwardly and somewhat rearwardly and are pivoted at their upper ends in the lower ends of downwardly and rearwardly extending radial arms o, attached to a rock-shaftp, mounted in bearings in the end plates.

In the normal position of the parts thus far described and as shown in Figs. 3 and 6 the endless-band carrier h bears upon the under face of the platen and being, as shown, substantially as wide as the platen is long makes contact with it centrally as well as at or adjacent its ends. Sheets of paper, cards, or envelops introduced between the platen and the endless carrier will take the direction indicated by the arrow in Fig. 6 and passing loetween these two members will be carried around under the platen. A spring 50, to be applied, as shown in Figs. G and 7, to each arm 7c or otherwise, serves to draw the endless carrier against the face of the platen, but permits of its being forced away therefrom to accommodate different thicknesses of paper or cards introduced between them. Obviously if the rock-shaft p be turned in the IOO IIO

ro` figures of the drawings.

Of course it is to be understood that the invention is not limited to the precise manner of mounting and operating either the endless-g band carrier or the endless-band guides.

Figsl, 2, and 4 show line-space devices operated by a hand-lever 11. They are of ordinary construction and form no part of this invention.

The common device of crowning the rolls zo or pulleys'upon which the bands `run to cause them to travel accurately may be employed in 'this construction. The crowning, however, will be very slight, so as not to disturb, practically, the parallelism of the different,

z parts of the bands or their uniform coactionl at all points with the surface of the plateni This crowning of the rolls would be so slight; that it would not be perceptible in the draw ings, and as it is a common expedient it haS 3o been thought not desirableto exaggerate thev drawings to illustrate it. j vIn the construction illustrated the printing line or point may be at 12, Fig. 3.

The term cylindrical platen used in the 3 5 claims includes ordinary forms of rotary platens usable in writing-machines and which may be described generally as cylindrical,and does not require that the periphery of the platen shall be a perfect circle.

In this specilication and in the claims the endless-band carrier has been described as positively driven. By this term is meant a definite driving of the endless carrierregardless of its frictional contact with the platen.

In the drawings the carrier is so shown as definitely or positively driven by reason of its bite or hold upon its positively-driven roll. As stated in this specification, however, the same result may be produced in other 5o ways.

IVe claim as our invention- -f 1. In a writing-machine, the combination with a rotatable cylindrical platen, of an endless unitary band carrier adapted to travel at 5 5 the same time in contact with the central and side portions of the cylindrical surface.

2. In a writing-machine, the combination with a rotatable cylindrical platen, of an endless unitary band carrier adapted to travel at 6o the same time in contact with the central and side portions of the cylindrical surface, and means for throwing the carrier out of operative engagement withthe platen.

3. In a writing-machine, the combination with a rotatable cylindrical platen', of an endless unitary band carrier adapted to travel at the same time in contact with the central and carried around the platen toward the printf ing-point bythe conjoint action of the surfaces of the platen and carrier betweefi' which the sheets travel. p u

5. In a'writing-machine, the combination with a rotatable cylindrical platen, of an endless-band carrier running in contact with the central and side portions of the cylindrical surface and positively driven'at the same surface speed.

6. In a writing-machine, the combination with acylindricai rotatable platen, of a unitary endless band carrier arranged centrally of the platen and adaptedto run in contact therewith, and means-for driving Vthe 'carrier at the same surface speed as that of the platen.

7. In a writing-machine, the combination with a cylindrical rotatable platen, of a unitary endless band carrier of a'width approximately equal to the length of the printingsurfaceof the platen and adapted to run in contact therewith, and means for driving the carrier at the same surface speed as that of the platen.

8. In a writing-machinathe combination with a rotatable cylindrical platen, ofan endless-band carrier running in contact therewith in the same direction and positively driven at the same surface speed whereby sheets fed between the platen and carrier are carried around the platen toward the printing-point by the conjoint action of the surfaces of the platen and carrier between which the sheets travel, and means for throwing the carrier out of operative relation with the platen. 'v

9. In a writing-machine, the combination with a rotatable cylindrical platen, of an end- IOO IIO

less-band carrier running in contact therewith and positively driven at the same surface speed, and means for throwing the carplaten and carrier between which the sheets travel. s

l1. In a writing-machine, the combination with a rotatable cylindrical platen, of a posil `tively-driven endless-band carrier traveling direction of the hands of a watch, as viewed in Fig. G, the effect will be for the radial arm o and link n to throw the arm downwardly and move the endless carrier out of contact with the face of the platen or to permit it to become so slack as to allow of the adjustment by the operator of a sheet or sheets already in the machine. The large surface of contact of the endless carrier with the introduced sheets or cards carries them readily around under the platen as the platen is revolved and,

incidentally-by friction, it may be-the contiguous surface of the carrier is caused to travel at the same speed as the paper. As shown in Fig. 7, when the shaft p is rocked through a sufficient arc the toggle action of the arm o and link n will hold the carrier away from the platen. The rocking of this shaft may be conveniently accomplished by means of a projecting hand-lever q, keyed thereto.

A further important feature of this invention is the positive driving of the endless-band carrier at the same surface speed that the platen has. This may be conveniently done by means of a gear-wheel 1^, placed at one end of the platen and meshing with a pinion s on the shaft of the pulley g, Figs. l and 3. Experience has demonstrated that with an organization of this kind cards or sheets of paper forming a pile or collection of very considerable thickness may be introduced and carried around the platen without disturbance of their relative arrangement with quite the same facility that a single sheet or card may be handled. Aside from the advantages of operation, the structure is one of small cost, and the usual paper-table, along or over which sheets are fed to the machine, may be dispensed with. While the endless band at all points of contact with the platen presses the intervening sheets against the platen, this is particularly so at the forward roll t', which is or may be distinctively a pressure-roll.

As shown in the main figures of the drawings, front guides or bands are arranged just above the roll t' or forward portion of the endless carrier. These guides may be of appropriate width, but are relatively narrow, and are so mounted and arranged as to be respectively independently adjustable longitudinally of the platen and capable of being moved away from the surface of the platen. As shown in Fig. 6, these guides or bands t when in normal position press against and conform to the surface of the platen and are driven frictionally. When thrown outwardly for the adjustment of a sheet, they may pass entirely out of contact with the platen, if desired, or bear lightly thereon, as shown in Fig. 7. Each band passes around a roller u,

suitably adjacent the rollerz'and having bearings in the lower end of the curved arm c, preferably of channel-iron to afford sufficient rigidity, turning at its upper end upon a bolt w, projecting laterally from a horizontal arm :r and having upon its end a pulley y, around which the band also passes. The horizontal arms r extend part way across the top of the platen and each forms part of a block z, movable upon a square or angular' bar 1, extending between the end plates of the frame and upon which the blocks are capable of being adjusted longitudinally by means of setscrews, as shown. The rock-shaft p, before mentioned, passes through apertures in th armsac and in lugs 2, also forming part of the blocks e and arranged, respectively, adjacent the arms 0c. From the shaft p between the parts a"l and 2 project upwardly arms 3, movable longitudinally on the shaft by means of slot-and-key connection and to which are pivotally connected the rear ends of links 4, whose front ends are slotted to embrace apin 5, fixed in the aperture 6, Fig. 8, of the part 7 of channel-iron fu, extending upwardly beyond its pivot-bolt w. When the rock-shaft is actuated by the hand-lever q, as already described, or otherwise the first action that is commenced is the swinging of the endless carrier h away from the platen, following which the pin 5 comes against the end wall of the slot in the link Il and the channel-iron arms u are swung upon their pivot-bolts w to throw the band carriers t away from the platen. The band carriers are normally pressed against the face of the platen by the springs 50, applied tothe arms 7a. When the parts are thrown into position shown in Fig. 7, the band guides t, as well as the endless carrier h, are maintained in their outward position by the toggle action between the parts -n o.

The rear roll of the endless carrier or that at the entry side of the platen need not be movable toward and from the platen, while the front roll may be. The latter in the construction shown acts as a pressure-roll, and between the two the endless feeder or carrier has a relatively long surface contact with the platen, and for that reason it is not necessary that there should be any great pressure between the platen and carrier. With ordinary feed-rollers contacting with the platen at single points only relatively greater pressure is required to enable the machine to perform the ordinary operations expected of it. Such reduction of pressure, possible with the present organization, has a beneficial eect on the action of the retaining-pawl acting on the platen ratchet-wheel, permitting more accurate seating of the pawl with less spring-pressure.

The guide-band rolls adjacent the roll of the carrier and which, as shown, are pressure-rolls may be movable; but the other guide-rolls need not be, and the latter being placed a suitable distancey from the face of the platen act, with the aid of the bands, to deliver the printed sheets or cards from the platen.
