Y Application tiled March llil `Serial No. 98,164.V (No model.)

Be it known that I, CHARLEsJ. BELLAMY, a citizen of the United States, residing at Springfield, inthe county of Hampden and Commonwealth ofMassachusetts, have invented a new and useful Type-Writer Attachment, of which the following is a specifica- My invention relates to improvements in atachments for type-Writers with which rolls of paper may be used and in which certain peculiar devices for handling the rolls and the paper and for manifolding are employed,

all ashereinafter fully described, and espepecially pointed out in the claims; and the objects of my improvement are, first, to provide Ymeans for attaching rolls of paper to a type-writer carriage; `second,to furnish means for manifolding; third, to provide a tension appliance for paper-rolls; fourth, to construct lan attachment with which to successfully `manipulate paper from one or more rolls or from a single roll and in sheets or in sheets without any roll; fifth, to provide means for uniting the ends of the manifolding-apron; sixth, to effect a saving intime and labor,

and, seventh, to provide mechanism embodying these advantages and carrying out these objects in a practical manner. It is a signal advantage to be able to make copies of the matter Written by the machine or not, at the pleasure o f the operator and with a minimum amount ot' trouble required to effect the change.` Previous devices for the use of pa` per-rolls in type-Writer Work have shown se-` rious defects in` operation, and my invention overcomes such defects in apractical manner. lt is obvious that substan tial advantages lnust accrue from the use of rolls of continuous strips fed continuously after the paper has once been inserted between thecarriagerollers, no stop being necessary for a fresh supply until the rollsbecome exhausted.

Much time and `labor are conserved by the use of paper-rolls, whether a copy is taken or not, but` naturally more in the former instance, and although my invention is useful when separate sheets are employed its greatest advantage shows forth in the manipulation of rolls.

Myattachment may be made light and compact and so constructed as tobe applied to almost anyordinary type-writer. I show it applied to the carriage of a Remington `machine; but the same can be affixed to other ,makes of type-writers without material or important change. Usually the attachment will be so arranged as to permit of ready connection with and disconnection from the writing-machine; but it may be afixed permanently to the machine.

` I attain the aforesaid objects by the mechanism illustrated in the accompanying draw ings, in whichf Figure lis a side View of a type-Writer carriage having my attachment mounted thereon; Fig. 2, a front view of said attachment, the bottom bar of the frame and one of the `holding devices being in section; Fig. 3, a plan view of the upper part of the attachment, the frame being in section; Fig. 4, a

.partial side View of the manifolding-apron, showing means for uniting the ends thereof; Fig. 5, an end view of a detached paper-roll Aand tension; and Fig. 6, a side View of a modified form of construction, the carriage-rolls also `being represented.

Similar letters and iigures designate like parts throughout the several views.

An'ordinary Remington type-Writer carriage a, slidingly mounted at the rear on a rod journaled at b and provided With the rubber roller or platen c and tension-roller d, is shown in Fig. l, the platen and tension-roller also being indicated in Fig. 6. My attachment is preferably arranged to be mounted on the hollow posts that rise from the rear bar of the carriage a, one of said posts being shown at e in Fig. l, although connections may be formed with other parts or at other points.

A `supporting-frz'tme comprising side uprights 2O 20, connected by a top bar 2l and a bottom bar or base 22, is mounted on the carriage a, being held in place by any suitable of the base 22 and arescrew-threaded to re- I CO` ceive the set-nuts 24 24, washers 25 25 being interposed between said base and nuts. Each carrier 23 has a flange 23", located below the base 22. When the nuts 24 are screwed down tight, the base 22 is firmly gripped between the flanges 26 and the washers 25, so that lateral movement of the carriers23 cannot take place. Abushing26,preferablyintegralwith the carrier, depends from the latter to enter the vertical hole in the post e and rear bar of the carriage et, while the carrier rests upon said post. Each bushing 26 is slotted at 26', so it can be expanded by the rod 27, which extends through a central passage in the carrier, head, and bushing. The lower terminal of the rod 27 is enlarged at 27' and has a projection 27 to register with a second slot in the bushing 26, whereby said rod is prevented from turning. A thumb-nut 28 is threaded to the upper end of each rod 27 and bears against the head 23'. Now in order to secure the frame in place it is first necessary to loosen the thumb-'nuts 28, also the nuts 24, if the bushings 26 have not already been fitted to the post-holes. Next adjust the carriers along the base 22 until the bushings 26 register with the post-holes, when the nuts 24 are tightened. Finally, turn the thumb-nuts 28 until the bushings are secured in position. This last is accomplished by the elevation of the rods 27 when the thumb-nuts are turned and the consequent expanding of the split or slotted bushings by the enlarged terminals of said rods.

When mounted on the carriage, the frame and the members supported thereby move with said carriage either when it is reciprocated or turned upand down. All parts of the frame and members must be high enough to clear the type-writer frame when the carriage assumes its vertical position, except when used with makes of type-writers in which the `carriages do not turn up.

Three slots 29, 30, and 31 are cut through each frame-upright 20, the first two opening through the front and rear, respectively. A block 32, slotted to receive an upright 20, is

fitted to the inside of each upright below thetop bar 21, and arms 33 and 34 extend forward and backward from said block, respectively. A bolt 35 passes through a hole in each block 32 and the corresponding slot 3l to receive a thumb-nut 36 on its threaded outer end. By loosening the nuts 36 the blocks may be raised or lowered within the limits fixed by the ends of the slots 3l, and then by tightening said nuts said blocks with their connected members are held securely in position. A roller 37 has its shaft 38 journaled in the front ends ofthe arms 33, and a roller 39 has its shaft 40 journaled in the rear ends of the arms 34. A pulley4l is fixed on each end of the shaft 38, and a pulley 42, of larger diameter than the pulley 4l, is fixed on each end of the shaft 40, the pulleys on opposite shafts being connected by cords or elastic bands 43 outside of the uprights 20.

"elastic bands.

By this arrangement the roller 37 is driven a little faster than the roller 39, but in the same direction, for the purpose presently to be described. The shaft 44 of a tensionroller 45 is journaled in arms 46 46, each pivoted at 46 to one of the arms 33. Springs 47 47, attached to the pivots 46', are arranged to force the roller 45 into contact with the roller 37. An arm 48 extends backward from each-upright 20, andthe shaft 49 of the roller 50 is journaled in the rear end thereof.

A hollow winding-drum 5l is provided with trunnions or a shaft 52, which has its bearings in the bottoms of the slots 29. A pulley 53 is fast on each end of the shaft 52 outside of the upright 20. Some means for attaching the end of a strip of paper to the drum 5l must be provided, as the slot 51, extending horizontally through the periphery thereof. By inserting the end of a strip of paper into the slot 51' and turning the drum 5l a little the strip is connected to the latter and may be wound thereon.

A short distance above the base 22 each upright 2O extends forward and then upward for the greater part of its length, and a short rearward and upper extension or ear 54 is formed on said upright back of the forward extension, a horizontal space or bearing 55 being left between adjacentedges of the vertical parts.

Continuous strips of paper suitable for type-writing purposes are rolled up for use with my attachment, these rolls being provided with suitable holders, as trunnions or shafts, projecting from :the ends thereof. Said holders supplied with paper-rolls, and the tension appliances that go with them constitute an essential feature of my invention. Such a roll and appliance are shown detached in Fig. 5, the latter consisting of a rod 56, extending across and projecting beyond the face of the roll 57 and held againstthe periphery of the same by some resilient means, as an elastic band 58 at each end, connecting the projecting ends of said rod and the holder or shaft 59 or a grooved enlargement thereon. Springs may be substituted for the This tension appliance prevents the paper from unwinding and serves other purposes presently to be explained.

The shaft 59 of the paper-roll 57 is mounted in the slots 30 of the uprights 2O above and in contact with the drum 5l. On the outer ends of the shaft 59 are fixed pulleys 60 60, connected by crossed cords or elastic bands 6l 6l with the pulleys53. The pulleys 60 are slightly larger than the pulleys 53, so as to accelerate the speed of the drum 51, which is driven by the crossed bands 6l in the opposite direction to that of the roll 57. This is the copy-strip roll. Owing to the difference in size of the aforesaid pulleys, it is obvious that the bands 6l will slip more or less on the pulleys of the driving-shaft 52 during a portion of each revolution, especially as the feed-roll grows smaller with IOO IIO

particularly well adapted for use in this atj slack between the roll 57 and type-writer with the shaft. 33'` rollers which would naturally result from the jerking motion imparted to the paper by lsaid rollers. The provision for accelerated speed is found useful, moreover, in offsetting the retarding eect of friction and slipping and in keepingthe strip taut between the type-Writer rollers and winding-drum, thus preventing bagging and uneven winding. These elastic belt connections also serve the purpose of' holding the roll 57 in close frictional contact with the winding-drum, thus furnishing one element in the required tension, as well as assisting to rotate the drum.

The shaft 59 of a second or original striproll 57 has its bearings in the` ears 54, one of said ears being slotted to permit of the easy removal and insertion of said shaft. A fitr ger 62 ispivoted at 63 to the slotted ear, and the upper curvedr terminal of said finger is `normally held over the adjacent end of the shaft` 59 by means of a spring 64, extending between the lower terminal of the linger and a screw 65 in said ear. A stop-pin 66 projects from the ear into the path of the finger By actuating the finger 62 away from the shaft 59 the same can be readily removed and another shaft with a fresh roll thereon substituted. A tension- `rod 56 rests upon thebearing-snrfaces 55 and `necessary for the drum and its accompanying paper-roll, `as shown in`Fig. l. Here the bases of the winding-drum journals or slots 29 constitute stops, and the drum itself serves as a rotary member,which is caused to bear against said stops by thepull of the paper as it passes partly around saiddrum from the roll 57. elastic bands are found especiallydesirable in connection with a paper-roll and its tension-rod, because where the angle at the point of" departure of the strip from the roll is acute 'if the bands were not crossed the rod would be likely to act as a complete stop to the movement of `the` roll, especially if the angle is a sharpl one, since the tendency of straight belt lconnections would be to rotate the rod in a direction opposite to that of the Elastic bands are tachment, since theyalways tend to take up sizes.

The manifolding or copying apron A consists of a normally endless band provided with a copying medium, except at and adjacent to the jointed sections of said apron and preferably only on the inside. The apron is adapted to travel between the carriage-platen c and roller d, over the rollers 37 and 39, and in contact with the roller 50.

In order to facilitate the operation of inserting the apron A in and removing it from the carriage and attachment, it is necessaryV to have -t in the form of a strip and provide some suitable means for uniting and disuniting the ends of said strip at will. means may be employed for this purpose; but l find that a simple and convenient union consists of interlocking projections A at the ends of the apron A, forming casings, with a thin strip 67 run through said casings. The strip 67 can be easily removed from the casings orinserted therein. The connection between the ends of the apron must be thin and narrow enough to pass, with a plurality of sheets of paper, readily between the carriageplaten and lroller and over or around any other rollers that may be used to support said apron.

The joint or connection which I use comprises only two thicknesses of cloth, with that of the connecting-strip, which latter may be almost as thin as a sheet of stiff paper. strip of this kind is quite stiff enough for the purpose and may be easily and quickly threaded into the casings, where it keeps its place without difficulty and with said casings distributes thestrain evenly, so that the apron is not pulled out of shape.

It will be perceived that the casings on the two ends of the copying-apron, as well as the strip used to connect them, occupy a certain amount of space on said apron and that it will be impracticable to copy through these sections. Hence it is of vital import-ance to so construct the apron that the process of taking a copy shall not be interfered with. In order to avoid any difficulty of this nature, I make my apron of a length or circumference that shall be a multiple of the length of the sheet or page of paper on which copy is to be taken. Thus the same portion of the apron always comes opposite like parts of the aocoinpanying sheets or pages if properly started. Furthermore, the non-copying sections of the apronthat is, those sections made up of the casings and connecting-strip-are identical in dimen'sion in the longitudinal direction of the apron with the portion of the accompanying sheet or length of paper on which no copy is required, or, in other words, with their combined top and bottom margins.

Before inserting the apron A into the ma'- chine and attachment it is necessary to loosen the thumb-nuts 36 and lower the blocks 32 until the bolts 35 rest in the bottoms of the slots 3l. Now pass one end of the apron A between the platen c and the roller CZ and be- Various IOO IIO

tween the rollers 37 and 44, the latter, with its spring-pressed arms 46, being raised for this purpose. Next carry the otherend of said apron upward, back of the roller 50 and over the roller 39, and unite the two ends with the strip 67. Finally raise the blocks 32 until the proper tension is given to the apron A and tighten the thumb-nuts 36. By raising or lowering the blocks 32 any desired change in tension of the apron can be made at any time. The inked or carbon surface of the apron A is on the inside when said apron is in place. After placing the apron A insert a roll 57 above the drum 5l, lead the end of the strip of paper of which said roll is composed from the bottom of the roll backward between it and said drum, around the back of the latter downward between thecarriage-platen c and roller d and around said platen, thence upward to the drum, where it is attached, as hereinbefore explained. This strip is designated by the reference-letter B and may be termed the copy-strip.7 Next lead the end of the strip C from the bottom of the lower paper-roll 57', over the tension-rod 56, forward between the platen c and roller d and around the former, thence upward between the rollers 37 and 45 and out beneath the top bar 2l, which serves as astraightedge orknife against which said strip is torn off from time to time,

as occasion requires. The tension-rod 56 is .held against the roll 57' by the bands 58 and against the bearing-surfaces by the pull of the paper as it is drawn through the typewriter, said rod being revolved by the paper and said bands. The strip C receives the original impression from the type-writer and may be termed the original copy-strip, and the apron A is caused to transfer a copy of `this impression to the strip B. The arrows indicate the directions taken by the rotary members and traveling strips and apron when ythe platen c is turned to actuate the paper forward for a new line; but it will be understood that the paper can be actuated in the strip B unwinds from its roll it is wound `upon the drum 51, since the latter is rotated by the pull of the paper and by the bands 6l,

which also serve to draw the roll into closer lcontact with the drum and to prevent possi- In order to remove the drum, cut the paper between the platen c and said drum and lift the shaft of the latter out of the slots 29, when the copy may be unwound. It will be understood that the copy-strip roll rests upon to enlarge upon the same. v

A guard 68, SuppOrted by the bar 2l, overhangs the front of the attachment to prevent the end of the strip C from falling forward before it is grasped between the rollers 37 and 45. After passing between the rollers 37 and 45 the strip C is taken care of without any difficulty, owing to the fact that these rollers have an accelerated speed imparted thereto by the bands 43. This provision not only keeps the strip C taut after it leaves the type-writer, but also the front of the apron A, and increases the efficiency of the coacting mechanisms. In Figs. l and 6 the front reaches of the strip C and apron A are shown separated for the sake of clearness in illustration, but in practice they would be contiguous.

One or both strips B and C may have letter-heads, bill-heads, or like matter printed thereon at regular intervals and be perforated at predetermined distances before being rolled up. If there is no printing or perforation, it is desirable to have the type-written matter so spaced that the strips can be separated into pages or sheets, as before. Hence the apron A should be a multiple of the length of one of these-sheets or pages, as has been stated hereinbefore, because there is no ink or carbon on the projections A', nor would it be practical to strike the strip 67 with the face of the type. Care must be exercised in inserting the strip so that the projections A' will arrive beneath the platen c coincidentally with the place of division of two of the before-mentioned sheets.

As herenbefore eXplained,a paper-roll with a tension-rod and resilient means to draw. it against said roll are employed in connection with the attachment described. As a complement to the roll, tension-rod, and resilient means stops are furnished for said rod,whicl1 is caused to bear against said stops by the pull of the paper. The rod may be located either above or below the stops, according to the direction which the paper is to take. If the paper passes from the bottom of the roll over the rod in a downward direction, the rod is placed above the stops, as best shown in Figs. l and 6, where the bearing 55 serves as such a stop in the first instance and the arm 69 in the other; but if it should be necessary to take theA paper from the top of the roll and pass it under the rod in an upward direction the rod must be placed below the stops. As-the paper-roll grows smaller the ytension-rod approaches the shaft and always operates to hold the paper in place while being rewound or when the roll is stationary and to regulate the unwinding of the same. This is true in all cases. To recapitulate, it may be stated in a general way that the tension-rod is drawn against the paper-roll by resilient means and caused to bear against .suitable stops interposed in its path by the pull of the paper, which must pass partly around said rod.

This attachment is compact and easily manipulated either in the removal of any of its detachable members or in the operation re- IIC quired for writing. The paper strips and apron are arranged and adapted to work in unison Without slipping, twisting, or other- Vwise interfering with their proper passage through the carriageof the type-writer.`

Several modifications are shown in Fig. 6,

which will now be described. The' copystrip roll has its shaft supported at the bottom of the slots 29 in this oase, andthe drum is supported above and out of contact with l said roll, a slot 30a being provided in each upright 2O to receive the drum-shaft, said `slot preferably opening through the front of` said upright.. An arm or stop 69 projects elastic bands with the roll-shaft.

from the back of each upright to receive a tension-rod 56, which is connected by crossed A pulley 70 is fast on each end of the roller-shaft 49 and connected with the pulley 53 on the drumshaft byaband 71,4the pulley'O being larger than the pulley 53. There is no connection between the paper-roll andrdrnm, and the `latter is actuated by the apron A through the An original-copy-strip roll and tension ap-` pliance may be employed with the apparatus shown in Fig. 6, or two tension-rollers 72 and 73 can be used. The trunnions or shaft 74 of the rear roller 72 is journaled in the bearings provided bythe wings 54, and the trunfaces 55.

nions or shaft 75 rests on the bearing-sur- A crossed elastic band 76 connects corresponding ends of the shafts 74 and 75. The rollers 72 and 73 are useful when the original-copy strip C is taken from a roll placed at a distance from the attachment, said strip being led under the roller 72 and over the roller 73, saidrollers acting as tensionguides for the paper. These rollers are ap-V plicable to the construction shown in Fig. 1. Aside from the differences pointed out the operation of the attachment shown in Fig. 6 i's similar to that shown in Fig. l.

When no copy of the original typewritten matter is required, the apron may be removed and only the strip C run through the carriage, or the strip B maybe used, the operation of either and their respective running and regulating parts being practically the same as previously described. If the strip B is used for the original copy, it can `be carried upward between the rollers 37 v and 45 or wound on the drum, as desired,

said dru m furnishing the tension when placed as shown in Fig. l. On the other hand, either original paper or the copy-paper may be fed 4the apron.

in detached sheets in either construction or both original and copy may be made on de tached sheets, thus dispensing with one or both rolls, as the case may be. In case it is desired to take the copy on detached sheets rather than on paper from a roll a detached sheet is fed down between the actuating-rollers ofthe typewriter between the apronA and the platen c instead of feeding down the strip from the copy-roll 57, the paper-roll as Well as the drum 5l being removed for the sake of convenience in manipulation should it be deemed necessary. Thus the impression given in operating the type-writer to the strip C, which is fed on the outside of the apron A, is transferred by the latter to the detached sheet, which when released from the rollers c and dafter receiving the desired copy can be takenout as delivered back of said apron.

copy-roll 57 and drum 5l are retained and a `detached sheet is fed into the machine behind the apron A, coming out in front of the same after being printed, to be removed as Soon as released from the machine-rollers. Vhen detached sheets are to be used for both original and copy, the roll 57 and drum 51 may be removed, the roll 57l is dispensed with, and two sheets are fed between the machine-rollers, one back of the apron A and the other in front of the same, said sheets.

being removed as they emerge from said rollers. Then, again, the apron can be removed and sheets of carbon-paper employed with strips from both rolls or with one ofsaid strips and detached sheets. In the event of using both rolls 57 and 57 with carbonpaper in place of the apron A said sheets may be fed down in succession between the `strips B and C in the path, as indicated in both constructions, Figs. l and 6, taken by The carbon-sheets come out of the machine in the path taken by said apron and can be removed for further use. When detached sheets of paper for the original and sheets of carbon-paper instead of the apron are used, retaining the roll 57 for the copy, a sheet of paper with a carbon-sheet on its back side arev fed down together behind the strip B and pass between the type-writer rollers, from which they are received when released in the usual manner, While the copy-strip B goes to the winding-drum 5l, as before. If it is desired to use detached sheets for the copy, retaining the roll 57', but dispensing with the apron A, a sheet of paperdesigned to receive copy and a carbonsheet on the front side thereof are fed between the typewriter rollers with the strip C and between such strip and the platen c. In passing out from between the type-writer rollers after the strip C has received the original impression and the detached sheet the copy through the `interposed carbon-paper said strip C pursues its upward course, as hereinbefore explained;

but the detached sheet and carbon-paper are` In case it is desired to use de- .tached sheets for the original impression the IIO taken out as soon as freed from the machinerollers. In this last case it is obvious that the copy-roll 57 and the drum 51 may be removed, since they are not employed if the space occupied by them is required for the more convenient manipulation of the other features.

It will be understood that numerous variations in the relative positions of the copystrip roll and the winding-drum are possible; but they are too obvious to vrequire further illustration or description, except to say that if frictional contact between the roll and drum is not desired the shaft of whichever is uppermost should be positively journaled, while if frictional contact is desired the shaft of whichever is uppermost should be received in slots cut low enough to permit the same to` drop.

Various changes of minor importance other than those herein mentioned may be made in my invention without departing from the nature thereof, and all such variations whether in shape, size, construction, or arrangement of parts are intended to be included in and covered by this application.
