This invention relates to hand writing machines of the type where a strip of paper is fed across a platen on which memoranda may be made by hand: and the strip advanced by regulated steps and torn from the strip for filing or other purposes as desired. y I

The object of my invention is to provide a handwriting machine the platen rollers and advancing mechanism of which are con structed as a unit and maybe securedin any suitable casing, or in any type ofshowcase, table or desk where desired through which to feed a continuous strip of paper from a roll or ziz-zag stack. I v -A further object is to provide a device for the nurposeset forth which is comparatively simplefin construction readily assembled and positive "in operation an in which the roll of paperjis hidden from view and only a short strip'is exposed as it passes over the platen, vand in which the paper may be advanced by regulatedsteps by a wheel or. other means conveniently arrangedunder the heel of the hand as the memorandum is made.

With these and such other objects in view as will be apparent as the description proceeds, the invention resides in all the novel features of construction and combination of partsherein disclosed and particularly pointed out in the appendediclaiins.

In thedrawings Fig. 1 is a side elevation i of the complete handwriting machine in its 1; Fig. 6 is a side elevation of the paper I advancing unit; Fig. 7 is a top plan view of the paper advancing unit, the central part of the casing being shown in section; and

. Fig. 8 is a top view ofthesides, top and bottom members of the paper advancing unit disassembled.

In describing my invention, reference is 1929. Serial No. 352,627.

which like reference numerals are' used to designate like parts in the several views,

In the embodiment of my invention illus trated in the drawings, 10. designates a onepiece casing molded or stamped from any suitablemateriah'thebottom of which is open. In the top is a suitable openingll under which the platen and paper advancing unit designated generally by the reference numeral 12 ismounted. The casing is made longer than necessary to house the unit and the opening 11 is a sufiicient -distance from the :one end so that a rest for the arm-is provided at 13. The opposite I and into a boss 16 (indicated in dotted lines in Fig. 4) onthe opposite side wall.

The paper advancing mechanism "and platen are constructedas a self-contained and separable unit 12 a which may be mounted in any casing desired. 7

The frame of the unit 12 comprises two

side plates

20 and 21, a bottom plate 22 which includes a semi-cylindrical end member and a top plate or platen 23 all shown in dissassembled relation in Fig. 8.

The

side plates

20 and 21 are each made with inwardly bent lugs 25, on their bottom edges and a laterally directed portion 26 bent in from one end. Forconvenience in describing the arrangement of parts the end of the side members provided with the inwardly turned portions 26 will be termed the roller end oi the frame and the opposite end will be called the platen end. The top and bottom edges of the side members 20 I and 21 near the rollerend are provided with arcuate cut-out portions 27 and 28 (Fig. 6).

The bottom plate 22 comprises a flat bot tom portion 30 with its edges 31 folded inwardly parallel with but spaced slightly from the bodyportion30 toprovide guides for the paper. The outer .ends of the flanges 31 are spread somewhat as at 82 to facilitate the threading of the paper into the guides and to prevent catching of the the plate and forms the journal for th 1 paper as it is drawn therethrough. The opposite or inner our 33 of the bottom plate 22 is bent into a semi-cylindrical form to conform to the arcuate portions 27 and 28 of the side members, and is provided at each side with short extensions 34 and which fit into the cut-out portions 27 and 23-respectively. The bottom portions of the member 22 rests on the lugs 21 of and is positioned between the side members and with the projections and 35 of the curved end engaged in the arcuatecut-out portions 27 and 28, the said

members

20 and 21 are clamped tightly to the member bytie rods 36 which extend froom one side member to the other.

Positioned in the semi spherical endinember 33 is a roller 37 which is spaced therefrom far enough to permit :a'sheet of paper topass therebetween. =-The roller 37 is cured non-rotatably on an axle member which in turn isjournaled in the

side plates

20 and 21. Rigidly secured to one end of the axlemember 38 by the screw 38 on the outside of the plate 20 is a gear wheel '39 having a flange 40 which extends through end of the axle. The roller 37 is clamped tightly against the flange lO by a nut 41 at the opposite end of the axle. To prevent end play of the axle in the frame, a flanged nut 12 is threaded onto the axle from'the outside of the plate 21, the flange 13 tightly abutting the nut -12 serving to loclr the same in place andalso providing a smooth journal where it passes through the plate 21 in which it rotates with the axle 38.

Journaled in the side plates '20 and 21 near the opposite end of the unit 12 is a second axle 4-5 which has a gear wheel 16 secured non-rotatably thereto outside the plate 20 by the screw i7. Secured nonrotatably to the other end of'thc axle by a. nut 48 a-notched wheel 19 of such a si e that the projections 50 thereon extend slightly above the top edge of the side plate 21 when t ie wheel is rota-ted.

Secured for rotation on the side plate 20 bythe bolt 52 and intermes ug with the

gear wheels

39 and 46 is an idler gear wheel 53.

The semi-cylindrical end member '33 is provided with two elongated openings 55 extending longitudinally tl erect and disposed between the line of the inwardly projecting portions 26 of the side members ant the axis of the roller 37. Between the openings for the axle 38- and the inwardly projecting portions'26 each side plate is provided with :a short slot 56 in which an axle member 57 which extends between the side plates has some movement toward and from the roller 37. On this axle 57-are two sn rollers 58 arranged so their outer perip iesextendthrough the openings '55 in F member 33 and Contact with the roller 37 or with the paper when it is threaded over the roll 37. Secured to each end of the axle 57 immediately inside of the

side plates

20 and 21 are collars 59 each having a radially projecting lug 60. Compression springs 61 engage over the lugs 60 and extend between the inwardly projecting members 26 of the side plates and the collars 59 on the axle 57 for yieldingly pressing the rollers 58 toward the feed roll 37'to hold the paper there-against.

The platen 23 is provided with attaching portions 65 bent laterally from the side edges thereof by which the same is secured to the

side plates

20 and 21 by screws 66.

The end 67 of the platen near the roller 37 is bent down slightly and extends beneath the end of the member 33 to facilitate threading of the paper therebetween.

The unit 12 when assembled is positionedin the casing-10 with the platen 23 directly under the opening 11 and the operating wheel 49 extending slightly above the top surface of the casing. Spacing blocks 70 are interposed between the sides of the unit 12 and the casing, and screws 71 which pass through the sides of the casing 10, spacing blocks 70 and screw into the side plates '20 and 21 securely holding the unit in place.

Across the casing 10 at the top edge of-95 the platen 23 a cutter bar 75 is secured by screws 76.

In operating the device, the paper 14 from the roll is threaded through under the guides '31 on top of the plate 30 and about the feed roll 37, between it and the semicylindrical end 33 which guides the paper thereabout, and from the feedroll over the platen 23 and under the cutter bar 75. The

rollers 58 hold the paper 14 tightly against the roller 37 so there-will be no slipping of the paper when the feed roller 37 is rotated.

After writing on the paper 14 which is presented in the opening 11 over the platen 23 the wheel 49 is rotated by-a forward push with the heel of the hand under which it is conveniently located, and by means 'of the gear-s39, 53 and 46, the feed roller 37 is rotated, and a freshstrip of paper=is exposed. detached by aquickpull across the cutter bar 75 under which it passes.
