'and exact description thereof, reference be- The obJect ofithe invention is to provide a ytypeivriteir with an attachment for manifielding, whereby a number of carbon copies maybe made with a single operation of the machine and whereby said copies may be automatically removed from the platen.

Said roll 17 is a tension roll adapted to rotate in a direction so as to rewind the ribbon 18 u on itself after said ribbon has been unwoun from it, and, as shown in the` drawings, is located back of and. slightly above the longitudinal" central axis of the platen' and` is rotatively mounted in the end plates of the paper carriage. The roll 17 is supported by arms 12x secured to the end plates 12*l of the paper carriage, an consist-s of a tubular barrel 17"- (see Fig. 6 having a closed end=.1'(:"fl'to end closes the open end of the barrel L12 and provides rotative end bearin therefon@ v` 22 indicates a sprin coile upon the rod 19V and having an en 22* connected ,with the barrel and its opposite end 22D con-i nected to the rod 19.

Said gears are so arranged that a rotation of the roll 17 to rewind the ribbon 18 `will produceV a rotation of the roll 24 in the same direction to rewind the manifolding lsheet and the gears are so roportioned that the peripheral speed of t e two rolls will be substantiall vthe same.

` 34 indicates a paper roll rotatively supported in any convenient manner at the rear of the typewritin machine. As shown in the drawings, sa' roll is shown rotativelyY mounted on standards 35 rising upwardly from a base board 36 supported at the rear of the-machine in any convenient manner (not shown). From the paper roll 34 is unwond the manifolding sheet 34. The manifolding strip 34* is fed over the roll 24 which is provided with means for attaching said stri toits surface. Y 4

40 i 'cates a plate extending longitudinally of the roll 24 with its outer surface for part of the cylindric surface of said rell. rod 41 is removably secured in a slot 41x extending longitudinally of said plate.' As shown said rod has a reduced projection 41|l adapted to engage in a hole or aperture 40" in one end wall Aofthe slot 41%. AThe other end of saidrrod projects beyon the end of the roll 24 and is engaged by a swinging ratchet arm 42 pivoted to the end ofsaidv roll and adapted to retain said 1 rod in its associated slot 41". After swingsaid arm 42 outwardly to disengageit` :from` the end of the rod41, the rod 41 may be moved in the direction of its length to I withdraw its reduced end from the aperture 40 whereupon said lrod may be removed folding sheet.V

from the slot or groove 41".V By means of this constrl tion, after the manifolding,

strip has been wound upon the platen the required number o`f times, the part of the manifolding strip intermediate said and the paper roll 34 may be clamped 1n the groove 41 by means of the rod 41. A narrow longitudinal groove 40'l is formed in the surface of the ,plate 40 at the rear of the rod 41, so that after the manifolding strip has been connected to the surface of the roll 24, said strip may be severed by running a knife-edge through the groove 40.

The operation of my improved attachment is as follows: Then it is desired to'produce manifold copies of an original pa er, the forward end of the manifolding s eet 34'L is brought over the roll 24 and down into the apex of the angle between the forward end of the carbon ribbon and the surface of the platen 13. (See Fig. 2). The platen is then rotated' in the usual manner which causes the sheet 34 and the carbon ribbon to be wound about the platen, with the carbon ribbon superposed on top of the mani- The platen is rotated as many times as there are co ies to be made. When making the last rotation of the platen to wind the last section of the manifolding sheet on the platen, the original sheet upon which the original items are to be written, is fed overl the guide plate 15 into the space between the'irolls 16, 16, 16 .of the laten in the usual manner, said sheet thus yin on to of the outer section of the carbon rib on. T e writing isthen made upon the original sheet in the usual manner. The length of the circumference' of the platen 13 and of laten the roll 24, which is the same, is equal to the length from thev top to the bottom of the original sheet.A Thus eachV winding of the manifolding sheet on the 'platen represents the length from top to bottom of one ofthe manifolding copies when the sheet is severed into the `several copies which comprise its length. After the original has been written the rod 41 is withdrawn endwise from the roll 24 andthe manifolding strip 34a is clamped b said rod in the cove 41* inthe surface o said roll. The roll 24 duringthe winding ofthe manifolding strip and carbon ribbon upon the platen and during the writing upon the original has been rotat-in forwardly with the ribbon ro'lltoward t e platen and at a circumferential speed equal to the speed of the platen.4 The roll 24 has a predetermined anlg'ular and spaced relation to the laten suc that the end 18"L of the carbon ri bon attached to the platen is distant from the groove 40 in the plate 40 of said roll 24 measured by a strip being wound upon the platen and unwound from said roll 24. or vice versa, a space Iequal to the length of the original, winch, as before stated, is equal to the length of the circumference ofthe platen, and also to `the length of the circumference of the roll A blade or knife-edgev is then used to sever the manifoldingstrip in the plane of the groove liOl whereupon sections of said stri of like length and each equal to the lengtli of the original and containing a carbon copy thereof will drop from the roll 24 and may be gatheredup and distributed.

While in describing my invention I have` referred to certain details of mechanical construction and arrangement, manifestly these may be changed in various ways without departing from the spirit of my invention and I do not wish to be limited thereby except as ointed out in the appended claims.
