To all whom it may concern:

Be it known that I, ENGLAND'J. BARKER a resident of Morgan Park, in the county oi Cook and State of Illinois, have invented certain new and useful Improvements in Type-VVriters, of which the following is a clear, exact, and complete description.

The object of my invention is to provide means for suplgilying" one or more continuous webs of paper to the longitudinali reciprocal platen of a typewriter from rol s which are journaicdin a vertical frame that is supported independently of the carrier in-Which said platen is journaled, but reciprocated therewith by virtue of means that removably connect it thereto. This I accomplish by the mechanism hereinafter full described and as particularly pointed ont in the, claims.

In the drawings: Figure l is a plan view of a typewriter having my invention applied thereto. Fig. 2 is a side elevation thereof. Fig. 3 is a perspective view of the rack in which the rolls of paper have bearings, removed from the typewriter but illustratin the manner in which it is removably secured thereto.

Referring to the drawings A represents a suitable supporting-frame, and B the transversely reciprocal carrier. The framework of the carrier is, preferably, rectangular', 'and :its ends are connected at the rear of the machine by a longitudinal bar a, and near the front of the machine by a rearwardly The shield I) is placed over the platen c, journaled in the ends of the carrier, and it is arranged in the usual manner at a tangent to the circumferential strip the typewi'itten work therefrom. A longitudinally disposed cutter-blade C is placed iiatwisc against and in front of the lower portion of the shield Z, but is separated therefrom a snlicient distance to permit of the work, as it is delivered from the platen c, to pass hetween it and the shield. The cuttcrdilade is considerably narrower than the shield, and its upper edge is `sharpened lo facilitate the tearing;r oli of the paper when it is desired lo remove it from the machine. The ends of this cutter-blade project upwards and torni arms c lhrr 'or, the u )per side edge of the upper portion` nl' which are provided with downturned pivotal lugs ci', that are pivotally connect ed lo the ends of the shield l adjacent to its upper edge. The arms c at one end of the blade C is provided with a suitable finger grasp d, by means of which the blade, C, can be raised or lowered, and at a suitable point adjacent to the pivotal lugs c2 its ends are provided with lugse, which are connected bly means of contraction rings e to a suitab e strap c2, securedto t e upper edge of the ends oit' the carrier above the portion of the flat metal strips D secured direct to the upper edge of the carrier, as shown. The action of the sprin sie upon the cutter-blade is such as to hol it securely in its position against the shield, or, when raised and moved to the limit of its rearward movement, holds it in the latter position.

The rear ends of thestrips D extend to the rear of the carrier, and have mounted upon and secured to their rear end portions, standards E, which are connected by an upper and lower horizontal guide-bar E', E', between which the paper strips pass from the feed rollers in transit to the platen.

I prefer to use three rolls oi paper in connection with a typewriting machine when my improvements are applied thereto. These rolls of paper are of suitable Width and are arranged and located parallel to.

each other iii the same vertical plane. Their' 'ends are suitably journaled in stationary centering devices ut one end and at theother to centering-plates 2 oii the ends oifspindles which are )ouriialed in lugs 3MB, carried on and projecting i'carvifiirdly from the upper ends of suitable fremde 4, which latter are pivoted at their lower ends to a perpendicular inverted U-shaped frame 5. Near their upper ends these frnniesl haiid-grasps (5, and their upper cndsare kept pressing toward lie said rolls by means 0f springs K, which are wound upon the stud projecting to the rear from the vertical frame .3,iiiid at one end held to said slipportiiig-t'rame in e. suitable manner, and

have the other and longer end projectiiif.; upwards and hearing' agi-:inist i pin 8 projecting inwards from said .traine 4, which latter, al this point, is bent or bowed to the rear to provide spare for and to accommodate the presence ot' spring T. Vlien it is desired to insert or remove the roll of paper all that it is necessary to do is to swing the frame 4 laterally are prpvided with` and thus move the centering plate out 'of engagement with the adjaccntendof the Same.

The lower ends of the inverted U-shaped vertical frame 5 are secured to andibetween the longitudinal sills ina truck 9. This rollers of the truck travel on a suitable rail or track 12, consisting of a horizontal bar, which is supported out a suitable distance from the rear of the supportingframe, by means of a truncated V -shaped clamp 13, the forward separated clamping arms of which have their extremities hooked or turned toward each other, and are adapted to clamp. the rear lower rail of the supporting-frame A of the machine', by means of bolts or screws 14, substantially as shown in Figs. 2 and 3 of the drawings. About midway its height the inverted U-frame 5 has a oke 15 secured to and projecting horizontally forward therefrom. The portion of this yoke,

extending substantially parallel tothe axis of' lhepaper rolls has two corres ending hooks 1G, 16, projecting forward rom it, which are located a suilicient distance apart and have their hook-shaped ends caught over and around the longitudinal bar a connecting the ends of the. carrier. The weight of the paper rolls and their support- -ing mechanism and the grip of the hooks 16 on the bar a of the carrier, are sufficient to cause the truck and the paper rolls supported thereby to move back and forth on' track 12 simultaneously with the carrier, but at any time should it be desired to feed ordinary letter heads, legal ca or separatc sheets oi. paper to the mac ine, the said truck and paper -rolls can be -easily and quickly removed from the machine.

In order to reproduce a manifold or carbon copy of the original work upon -one of the additional sheets of paper fed to the machine, I employ an auxiliary inking ribbon i F that extends longitudinally in 'ont of the platen in alinement with the original or record ribbon of the machine. The s ecic means for o eratin this auxiliary rib on is made the subject o a atent granted to me November 5th, 1907, o. 870,336, and it is therefore unnecessary to describe the same in detail herein. Suffice it to say, however, that the ribbon is wound upon s ools f, f',

mounted on suitable brackets G t at are secured to any convenient part of the carria Spindles hon which thespools are journa ed are provided with ratchet disks H and levers I loosely fulcrumecl pn said spindles that carrv a suitable aw m to engage with said ratchet. Levers 1 -are' keptnormall at right angles to the line of movement o the carriage by a leaf spring c and have their longer extended portions engaged by arms and K attached to the frame of the machine in theV manner shown. When one of the levers I engages its respective arm lJ or K said lever will move a slight distance and ,likewise cause its spool to wind up a portion of the ribbon by reason of the engagement of the pawl m with the ratchet. Arms J and K are provided with slots 7' and if: respectively and thumb-screws L and N for the purpose of adjusting the same to regulate the movement of levers I. If desired, one of these arms may be moved out'of the path of the lever I when the other is in use, and vice versa.

The track, the truck, and the paper supporting framework can be easily attached to and removed from most any machine now on the market having a reciprocating platen carrier, and either to old or new machines. To do this might require a slight modification of the construction of the hooks'l or equivalent mechanism, but all such changes l desire to be considered as contemplating within the scope of my invention, substantially as hereinbefore described.

What l claim as new is 1. A typewriting machine comprising a suitable Supporting-frame, a reciprocal car riage, a platen journaled therein, a shield therefor, a cutter-blade pivotally connected to the. ends of said shield and normally pressing down upon the same and common means for retaining said cutter-blade either at the lower or upper limit of its movement.
