- ie comprises a frame composed of lo and a left side 11, connected together by means of tie rods 12, 13, and mounted. on the typewriter carbeing secured thereto by means of 7', 18. or in any other suitable mandrawings represent a type of TYPE WRITER.

1923. Serial No. 64?,27

standard typewriter among those found on the market, and specially machined screws 17, 18, have merely been substituted for other screws already provided at the same places, retaining the carriage release levers 19, 20, so as to make it easy to mount the attachment on existing machines.

The rear lower part of the frame side pieces is also shown inserted over the column. spacing bar 21, and connected thereto, and to the supporting brackets therefor 22, 23, by means of screws 24, so that the mounting of said frame on the carriage is firm and effective.

From this it follows that the frame, and all its parts, travel with the carriage of the typewriter, which is operated in the usual manner, and which of course carries, among other parts, the platen 26, and the space indicating bar 27. The platen is supported by a frame, of which 28, 29, designate the end pieces, which may be raised from the position shown in the drawings, where small, or lower case type is printed, to the upper position where higher case or capital. letters will be printed, in a manner which is well known, by means of shift keys provided for this purpose.

The frame constituted by side pieces 10 11, and by tie rods 12, 13, 14, 15, is designer to support the rolls of paper which have to be fed to the plaum; in the present instance the rolls being three, one, 80, supplying paper for the or ginals, and two, 31, 32, supplying paper or ii and second copies. These rolls are respectively mounted on shafts 33, 34, 35, inserted in open bearings 37, 38, provided in each side piece, and said shafts are provided, if necessary, with suitable positioning means for the rolls, for instance collars 39, secured on the shafts 5 set screws 40.

The ends of the strips of paper 31, 32', issuing from the rolls, are fail to the platen in the usual manner, as shown in l ig. 1.. and. at the front or writing s de, copying ribbons 11, 12. are respectively inserted be tween strips 30, 31', and S1, 32, as clearly shown in Fig. 5; the device is then in position to simultaneously produce both orig r Li and copies, simply by operating the typewriter in the usual manner.

Ribbons 4.1, 42 (see Fig. 5), stretch for the entire width of the paper, and preferably, i: order. to utilize the full capacity of the sion spring 90, 91, fixed to a point 93;), in line respectively with pivots 75), 80 and with the central line of arms b, when midway between their two extreme positions. In other words, if rod 76 is in the position shown in the drawings, where the forked ends of ai-fins 87, 88, are to tne right of their respective pivot-s, springs 90, 9.1, tenf in said position.

l to maintain said arms However, if clip 89 pushes down arm to a point where the forked ends of arms 87, 88, ''ill have passed their intermediate position, and will assume a position slightly to the left of pivot, 79, 80, springs 90, Si, which have in the n eantime been stretched, will cause said arms to snap towards their es:- treine left position as soon as the dead point has been passed. It is therefore sutilcient to assemble the different parts in such a anner that clutch member 78 will become entirely disengaged after the dead point of arms 87, 88, has been passed, to insure continued operation of shifting rod 76 to completion; and the same remark applies to clutch member 72 when the shifting rod is moved in the opposite direction.

v the time when the clip at the leftend will ill) force down arm 84, again shifting rod 76 towards the right.

The feedi of ribbons (ll, 42, only takes place intermittently, and the actuating means thereof are arrang d so that the rib- )OQS will be fed during the en motion f the carriage, after the line spacing feeding of the paper has occurred. This is obtained iuei y by using the hue spacing lever SH, with which the pewriter is provided in the usual manner, the action of the same first to operate the platen so as to ie paper, and then to pull the carriage is the right. order to start a new The actuating means for the ribbon 1 become operative during said return travel of the carriage, and are inoperative towel";

during 'ts step by step travel caused by the wr 1n the reverse direction,

bearing 99 integral with bracket 69; sait gear being in mesh with said rack; a worm 100 mounted on said shaft in mesh with a worm wheel 101 mounted on shaft 68; and a ratchet wheel 102 operated during the return s'roke of the carriage by a pawl 103 mounted on a disc 10iintegral with gear 97, fixed on shaft 98. VJ hen the carriage moves to *ards the left, gear 97 is caused to revolve also towards the left, sprocket wheel 102 remaining stationary. lVhen lever 9% is operated, the platen is first caused to revolve for a given angle, and then the carriage is pulled to the right. The sense of the rotation of gear 97 becomes then reversed, and pawl 103 carried thereby will engage ratchet wheel 102 causing shaft 98 to rotate, and causing therefore, through worm 100 and worm wheel 101, the rotation of shaft 68 and of the reel connected thereto.

It is obvious that a positive ribbon feed, such as described, is preferable to a stepy-step motion s ch as might be caused by utilizing the same detent mechanism which is used for feeding the original printing ribbon in most typewriting lnachinesi Such a step-by-step feed might interfere with the step-by-step feed already obtained owing to the intermittent motion of the platen caused by the operation of the type-bars, and would make it necessary to employ special timing devices in. order to insure proper feed of the ribbon. The main objection to such a method of feeding; the manifolding ribbon or ribbons, however, resides in the fact that it is absolutely essential, in a machine of this kind, to preserve sensitive response of the carriage to the pulling action of the spring, each time a key is operated. It is upon this sensitive response that the speed attainable with a machine depends.

In an ordinary typewriter the ribbon feed noes not seriously interfere with the carriage feed, although both feeds are produced at the same time by the action of the same spring; but in a manifolding typewriter, the manifolding ribbon or ribbons are inserted between adjoining sheets, and are subjected to considerable friction for the entire width of the sheets. It takes quite a positive pull on the ribbon, in order to feed it under these conditions, andv an oven tension excl-toil by such a spring as available would be decidedly mu'eliable in overcoming this friction. To do this, the tension of the spring would have to be increased beyond the limits which can be safely used.

It is of course possible to use a separate spring for this purpose; but even then, the friction to be overcome is not always the same, and at times a jerk or a sudden action is really necessary in order to pull the ribbon through. Therefore I prefer to posiively drive the ribbon feeding means, prefiii) The requirements for certain forms of documents, like shipping slips, order records, etc, are not very exacting in what concerns the appearance of their edges, and in such cases tearing up devices of a suitable design may be used instead.

A device of this character is illustrated in Fig. 1, shown applied in connec ion with slots 106, similar to slots 105,106. Said device consists of a stationary plate 120, secured in position by means of bolts 110, 111, carrying a plate 121 formed with a pressure edge 122, pivotally mounted at 123. Said plate 121 is integral with arms 12%, to which a tension spring 125 is attached tending to hold edge 122 of plate 121 pressed against plate 120, shown at 121 in dotted lines. Plate 120, however, carries a stop member 125 pivoted at 126, and formed with an indentation 127 adapted to interlock with edge 122, normally holding the same in a position detachedfrom plate 120. A tension soring 128 tends to pull stop member 125 downwardly, and said stop member is provided with a handle 129 projecting through slot 105, by means of which the same may be operated.

1.1 a similar manner, arms 12 1 are provided with a handle 130 by means of which the same may be operated.

The device is normally set in the position shown in the drawing, where the paper strips are free to move between plate and edge 122. When the filled blanks have to be detached, stop member is raised by means of handle 129, freeing edge 122, and

spring 125 will then cause said edge to press the paper against the surface of plate 120. The slips may then be detached by a well known method, by tearing the same along the holding edge 122.

By means of handle 130, plate 121 is then moved back, until through the action of spriim; 123, stop membe- 125 again free to si .to c; .gement with edge .122, again bola g plate 121 in its normal position. The operation on the next sheets may then be started.

In the feeding of paper by means of the platen, a slipping tendency is liable to develop, especially when a number of copies are produced, which may cause the various sheets or stri s to be fed of uneven uantities; in other words, a relatiye motion takplace between the various sheets or strips. This is not open to serious ob ections when the rolls consist of blank paper, or of printed paper for the original only, and blank paper for the copies; but when a number or copies of printed and sometimes numbered blanks have to be produced, it is essential that corresponding copies of the same register at all times, and means to prevent slipping should preferably be provided, if frequent readjustments are to be avoided.

This result may be achieved in any suitable manner, and one among the arrangements which may be adopted is illustrated in fig. 6. In the same, the strips of paper are provided with equidistant perforations at the sides, at 131, adapted to be engaged by teeth 132 of a cylinder or roll 133, adherence of the strips on to said roll being insured by another roll 134 provided with grooves 135 to accommodate said teeth. Said rolls 133, 134, are preferably mounted on the device between the rolls of paper and the platen 136, and the simultaneous engagement of the perforations of corresponding blanks by teeth 132 will insure their correct matching in simple and positive manner.

In the form illustrated, the device is unobtrusive and practical, inasmuch as the line of vision of the operator is not interfered with, and the operation of the typewriter remains unchanged. Experience has proved that the carriage of the average machine can stand considerable weight and still readily respond to the action of the keys; but of course, when a large number of rolls of paper should be used, or rolls of extra large diameter and weight, it may be preferable to mount the frame supporting the same on a separate stand back of the typewriter, and

to provide suitable means for causingthe Q same to follow the movements of the typewriter carriage.

It is obvious, that when some of the matter written on the original should have to be left off some of the copies, the strips used may accordingly be of different width, or set off at one side of the necessary quantity.

The ire-rolling of some of the strips without cutting is also possible, and this may represent a desirable feature when it should be an advantage to keep records in a chronological or numerical order.

It is obvious from all that precedes, that devices en'ibodying my invention may be produced in various styles and forms, according to the purposes for which the same are intended, and may either be in the form of attachments for existing machines, or may form integral part of especially designed machines.

I therefore reserve myself the right to carry my invention into practice in all those ways and forms which may enter, fairly, into the scope of the appended claims.
