To all whom it may 00mm: v I

Be it known that I, GEORGE A. SE13, citizen of the United States, and resident of Ilion, in the county of Herkimer and State of New York, have invented certain new and useful Improvements in Typewriting- Machines, of which. the following is a specification.

My invention relates to typewriting machines and more particularly to. paper feed or controlling devices therefor.

The main object of my-invention is to provide a divided or two-part rock-shaft for the paper feeding or controlling devices so connected and supported that when either part or section is turned it will, after aslight lost motion, cause a turning movement also of the other part or section, whereby the paper feeding or controlling devices mounted on said parts or sections may be moved together.

A further object is to provide each shaft I rially modifying the structural features of such machines as they now exist. 7

To the above and other ends which will hereinafter appear my invention consists in features of construction, arrangements of parts and combinations of devices set forth in the following description andparticularly pointed out in the appended claims.

In the accompanying drawings, wherein like reference characters indicate corresponding parts in the various views,

Figure 1 is a fragmentary front elevation of a platen frame and some of the parts carried thereby including the margin feed or control devices of my invention.

atent to G. H. Smith,

ay 7, 1912. H In such prior devices each margin feed roller was separately released whereas in the present construction an operation of a reare disclosed in the tive to simultaneously release both margin feed rollers. In the present instance I have shown my invention embodied in a machine like the No. .10 or No. 11 Remington machine in which the invention may be readily introduced without materially modifying should be understood, however, that the invarious styles of The platen frame, comprising end plates 1 and a cross bar 2, supports a platen 3 and diagrammatically shown in Fig. 2. i

In front of the platen and below the printing line isa divided rock shaft designated as a whole by the reference numeral 6. This shaft extends throughout the lengthof the platen and intermediate the end plates 1 of the platen frame and comprises two separate and distinct parts or-sections. Each section consistsof a main body portion 7 which 1s rectangular in cross section and is provided at its outerend with a cylindrical portion '8, which has a bearing in a sleeve or bushing. 9 'threadedinto a tapped opening in an end plate of the platen frame. The sleeve has ahexagonal or octagonal head 10 adapted for a thin wrench and by which the sleeve may be threaded into and out ,of the tapped opening. The inner end of each bearing sleeve 9 coacts with a bearing shoulder 8 on its shaft section to resist an outer thrust of the latter. The outerend of each section of the shaft extends through its bearing sleeve and beyond the head thereof where it has a finger piece,.arm. or release ,lease key at either end of the platen is eifecthe existing structural features thereof. It

key 11. fixedly ing movement of the other slight lost motion between lost motion is permitted by tending at this to move away cured by screws 19. to

dric'al outer surface on in Fig. 4) upon which is fairly loosely operative relationship,

'pendently one tion,as seen at 11. As .best shown in Fig. 2, a contractile spring 12 is connected at one end 13 to its release throughits finger pieceon a section of the shaft, tends to turn the latter and causes the margin feed roller or device carried thereby to bear against the platen under spring tension orpressure. The inner end' portion of each section of the shaft is formed with a cylindrical bearing portion 7 which is receivedina bearing 16 formed at the free end of an arm 17 which sheet metal bracket 18. This bracket is sethe-cross'bar 2 and thus constitutes a support from the platen frame for "thei'n'ner ends of the sections of the shaft '6. Theinner end portion of each shaft section extends beyondits bearing and is slabbed "off on one side to form a fiat contact face 20 where it overlaps and coacts with" the corresponding part on the other section. The two end portions, thus combinedto make a lap-joint, present a cylinthe shaft (as shown fitted the flat faces 20 in so that a releasing movement of'one section will cause a releasse tion after a the two. This the flat faces 20 time [to cam or flex the inner overlapping ends of the shaft sections away from each other until arrested by the loosely surrounding sleeve 21, when the shaft sections can no longer move indeof the other but must move together, thus causingboth paper fingers 23 from the platen. The-sleeve 21 is arranged between the bearings 16 and is prevented from endwise movement by a sleeve 21 which keeps said bearings. I

" j The rectangular-or squared body portion .7 ofeachsection of'the shaft is surrounded .roller at its upper by a correspondingly shaped sleeve 22 adapted'to turn with the shaft but also adapted to w v Each sleeve 22 is formed integral withits paper finger 23 which extends up: from the shaft across the printing lineaand carries a margin feed end. a The power of the springs'12, exerted throughthe finger piece 11 and the separate section of the shaft, normally presses both margin feed rollers against the platen or the paper there- A'forward pull or'pressure on either finger piece 11 is effective to move both margin feed rollers away from the platen against the power of the springs V 12. In order to limit this movement of feed rollers 24 away from the platen I provide each finger piece secured thereto as for. in-

a key and at the other 7 end to a pin. 14 onthe associated end; plate :1. The'power of each spring 12; exerted constitutes part of a bent inwardly from" the lower end thereof this, being possible byreason of'the presence of the 'lap-joint, which motion between the sections.

' The usual forwardly extending projection of ear 27 is formed on each sleeve 22 for cooperation with stop pins (not shown) 7 to arrest the paper fingers andpreventthem from reaching the printing'point. M

It will be understood of course that the two slabbed off or flat contact portions 20 areloose or unattached to each other but have a bearing one against the other within the loosely surrounding sleeve, so that when one shaft section is turned it will first receive a slight independent movement and then its motion will be transmitted to the other section through the free, overlapping flat contact faces 20. 'Thus not only does the construction enable both feed rolls to be thrown off by anoperation of either section, or its finger piece 11, but it also enables thc springs to be self-balancing so'as to equalize the pressure of the separate feed rollers 24. If for example the thickness of paper is greater at one feed'roller than at the other, the lap ioint permits an automatic whole,-the construction is strong and firm and adapted to any lengthof carrlage and.

in practice is better than a single, continuous shaft'which is more apt to spring 'or sag or be distorted in action in throwing Off the margin feed rolls (particularly without ac'enter support) and 'which besides does'not lend itself well to a balancing of the pressures of the margin'rolls in a mounting thereof of the kind herein shown.-

'In assembling sleeve or bushing 9 is seated on the bearing portion 80f its shaft section. The section is then introduced endwise through the tapped opening in the end plate in which the associate bushing 9 is to'be received and is then passed through the sleeve 22 of the corresponding paper finger and through the bearing 16'for the shaft section and then into the sleev'e21. The bushing isthen shaft the parts each. bearing [or arm 11 with a stop or lug 25 which I affords aslight lost threaded'into-its end platefcarrying its shaft section along with it, by reason of the engagement of the'latter with the shoulder 8, thus moving the inner end of the section farther into the sleeve 21. .The other shaft section is introduced into place in a corresponding manner, the inner end of the shaft section being brought into the overlapping arrangement shown when the second section is introduced in place.

What I claim as new and desire to secure by Letters Patent, is
