GOING, OF MIDDLETOWN, CQNNECTIGUT, ASSIGITOR, BY MESNE ASSIGN- MENTS, T0 REMINGTON TYPEWRITER COMPANY, A CORPQRATION OF NEW YORK Application filed February 21, 1927. Serial No. 169,882.

My invention relates to typewriting and like machines and more particularly to improved means for supporting a roll of paper and connecting the roll holder or support to travel with the carriage, provision being made for severing a section of the paper from the web after it has been written.

The mainobjects of my invention, generally stated, are to providecomparatively simple, yet highly efficient, means of the character specified which are in the nature of attachments that may be readily attached to or detached from existing typewriting or like machines without changing the existing structuralfeatures thereof, and without -adding weight to the carriage which will inter fere with the usual case shifting and letter feed movements thereof.

To the above and other ends which will hereinafter appear my invention consists in the features of construction, arrangements of parts and combinations of devices set forth in the following description and particularly pointed out in the appended claims.

In the accompanying drawings wherein like reference characters indicate correspondingvparts in the different views:

ig. 1 is a fragmentary perspective view showing the upper rear part of a typewriting machine equipped with the devices of my invention.

Fig. 6 is an enlarged, detail, sectional view of the connecting means for the roll support and knife, the section being taken on the line 6-6 of Fig. Land looking in the direction of the arrows at said line.

The devices of my invention are shown in the present instance attached to No. 6 Remington-Noiseless machine, only so much of said machine being shown as is necessary to illustrate my invention in its embodiment therein. It should be understood, however, that the devices of my invention are not restricted to use in such machines but may be employed in various other styles of typewriting and like machines, wherever found available.

The power driven carriage 1 of the typewriting machine carries a platen 2 and is mounted in the usual manner on crossed hearing rollers to travel from side to side of the machine in a letter feed direction under control of the usual escapement mechanism, not

shown. The shift rail 5 on which the car-' riage issupported is adapted to receive a vertical case shifting movement from the ke controlled shift links 6, as is usual in suc machines. The usual main paper feed rollers 7 and 8, and the rollBrs 9 carried by the spring pressed bail 10 and coacting with the paper above the printing line, are provided to coact with the platen and feed the paper-11 forward as the platen 2 is rotated.

In order to attach the devices of my invention to the machine two rearwardly extending bracket arms 12 are detachably secured by screws 13 t0 upstanding members 14 which form part of the frame of the machine.

The bracket arms 12 have a traverse or su porting rail or rod 15 secured thereto y screws 16. The length of this rod corre-. sponds to the extent of travel of the typewriter carriage and constitutes a support the cross bar about midway in its length and on opposite sides thereof are two depending plates 18, secured at their upper ends to the 7 bar 17 by screws 19.. The lower end portions of these plates loosel embrace the rod 15 on opposite sides thereo and constitute sup orts for two plvots 20 on which are mounte two rollers 21. The grooved peripheries of these rollers bear on and travel along the support-' of each upright supporting member 22 has an upright open-ended bearing slot 24. A paper roll supporting spindle 25 has a circumferential groove 26 in each end thereof (see Fig. 5). The depth of each groove 26 is such as to leave the diameter of the spindle at this point substantially the diameter of the slot 24 in which. the grooved portion, of the spindle receives a bearing. The width of each groove 26 corresponds substantially to the thickness of the upright support 22. By this construction the spindle 25, together with the roll of paper 27 thereon, may be readily lifted from itsbearings to mount a new roll of paper on the spindle. When, however, the spindle is seated in its bearings the side walls of each groove 26 will engage the sides of the associated supporting member 22 and prevent an axial displacement of the s indle, without however interfering with the ree rotary movement of the spindle in its bearings as the paper is advanced from the pa er roll.

eans are provided for detachably mounting the paper roll 27 on the spindle 25, which, in the present instance, comprises two spool flanges 28 each preferably made of sheet metal and provided with an inwardly disposed wooden hub 29 secured to its flange by screws 30. The diameter of each hub corresponds substantiall to the central opening in the paper roll 27 so that the latter may be seated at its ends on the inwardly extending hubs and the flanges 28 willcoact with the ends of the paper roll to hold layers of paper against accidental endwise displacement. Each flange 28 is detachably secured to and adjustable along the supporting spindle 25. This is in order to enable a full paper roll to be readily placed on the spindle, when desired, and also to enablethe flanges to be adjusted to accord with paper rolls of different axial dimensions. The means in question in the present instance comprises a coiled spring 31 contained within a recess 32 in the hub of each flange and confined therein at one end by the associated flange 28, and at the other end by the bottom wall of said recess,

as shown in Fig. 5. Each spring surrounds the spindle and has a friction-tight fit thereon, so as to hold the associated flange in the position to which it is adjusted along the spindle. i

It will be seen that the roll holder comprising the cross-bar 17 and upright arms 22 constitutes a substantially Ushaped frame arranged directly above the supporting rail 15.

In order to support the roll holder in a vertically disposed position over the supporting rod 15, and connect it to travel with the carriage, I pivot on the members 22, at 33, two forwardly extending links 34. These links are united by cross rods 35 to compel them to swing in unison, and in effect provide a swinging frame. The forward end of each'link has an open-ended U-shaped bearing slot 36 (see Fig. 3), the open mouth of which is uppermost when the links are in the normal position. A headed pivot pin 37 is seated in each of these bearing slots, each pivot pin projecting inwardly from a supporting bracket 38 detachably secured by screws 39 to one of the usual arms 40 on the end plates of the typewriter carriage. From an inspection of Figs. 3 and 6 it will be seen that each bracket 38 carries an inwardly projecting pin 41 located directly beneath the 1 34 to permit a swinging motion of the linkwithout enabling ,thelink to be displaced from its pivot 37 until it reaches some such position as that indicated in dotted lines in Fig. 3. When each link assumes some such position, it may be shifted rearwardly, displacing it from its pivot 37, thus detaching the links 34 and the roll holder connected therewith from the typewriter carriage.

It will be understood that when the links 34 are connected with the carriage in the manner described, the entire direct weight of the paper roll and holder is borne by the supporting rod-or rail 15, such parts being arranged irectly above said rod. The links 34 merely prevent a fore and aft swinging movement of the roll and roll holder around the supporting rod 15, and connect the roll tend to interfere with the letter feed movement of the carriage.

In order to detach the roll holder from the machine it is merely necessary to lift it off the supporting rod 15 and tilt it forward until the links 34 assume a substantially upright position, as indicated in dotted lines in Fig. 3. The links may then be shifted rearwardly to detach them from the pivots 37 and the holder and paper roll may be removed from the machine.

it have provided a severing device by which the advance written section of the paper web 11 may be readily detached from the remainder of the web, as indicated in Fig. 1. This severingdevice is detachably mounted in place on the typewriter carriage and com-' prises two supporting arms 43 connected together at their forward ends as will hereinafter appear. Referring more particularly to Figs. 2 and 6 it will be seen that the rear en of each arm 43 is provided with an open ended inclined bearing slot 44, the open mouth of which is at the front, when the arms are in the normal full-line position, shown in Fig. 2, with the associated pivot 37 seated in the bottom or rear end of the slot. The rounded end 45 of each arm coacts with the associated pin 41, hereinbefore described, to permit a turning movement of the arm on its pivot, but to prevent the arm from being detached from the pivot except when the arm has been turned to some such position as that indicated in dotted lines in Fig. 2. When this position has been attained the open mouth of the bearing slot 44 will be in the rear of its pivot 37, and the arm is free to be shifted forward without being obstructed by the pin 41,.and may be displaced from its pivot and detached from the machine.

Each arm 43 also is provided with a rear- Wardly extending stop member or foot piece 46 which, when the arm is in the normal full line position shown in Fig. 2, bears against the front face of the usual tabulator stop bar 47 secured to the carriage by the screws 39. This limits the downward pivotal movement of the arms 43 around the ivots, holding the arms in normal position by gravity. Both arms 43 are constructed and connected to the carriage in a like. manner, each being connected at its forward end by screws 48 to one end of a severing or cutting bar 49. From an inspection of Fig. 4, it will be seen that the rear side of this bar is beveled at 50 to provide a cutting ed e 51. The length of this cutting bar is-su stantially coextensive with the length of the typewriter carriage and the bar is located, when in normal position, above the platen and to the rear of the front face thereof, so that paper as it passes upwardly and rearwardly from the printing line may pass to the rear of said cutting bar. A aper clamping member or bar 52 is provi ed at its ends with trunnion-like pivots 53 which are received in bearing openings in the supporting arms 43 toturn towards and away from the cutting bar into and out of clampingbcooperation therewith,or with the paper we which passes between the clamping bar and cutting bar. A finger piece 54 is secured by screws 55 to the clamping bar to control its movement into and out of clamping position. A stop pin 56 is mounted on one of the arms 43 and projects inwardly therefrom into the path of the lower end portion of the clamping bar 52 and limits its pivotal movement away from the cutting bar 49.

. It will be understood that the supporting means such as are arms 43 and the cutting bar 49 are ri idly connected and virtually constitute a rame detachably connected to the carriage at 37 and that suchframe, together with the clamping bar 52. carried thereby, maybe readily attached to or detached from the typewriter carriage as a sin le unit. This device is mounted to shift wlth the carriage in the case shiftingmovements of the latter and when in place is always maintained at a uniform distance from the printing line. The representation of the machine in Fig. 1, due to the character of the perspective, illustrates the machine very. much fore-shortened. It should be understood, however, that the view is intended to illustrate a carriage of ordinary length of a No. 6 Remington-Noiseless machine equipped with the devices of my invention.

Various changes may be made in the con struction, and certain parts thereof may be employed without others, Without departing from my invention as, it is defined in the accompanying claims.

What ll claim as new and desire to secure by Letters Patent, is
