This invention relates to typewriting machines and typewriting and accounting machinesof the 101; L V V rails indicated at'4' connectedby'cross bars, certain'of which are indicated at fi. The machine so-called Elliott Fisher'or'flat'platen" type and more particularlyto clamping devicesior clamping cards" and similar worksheets on'the platen.

Certain objects 'of the invention are to inr-v prove the construction and mode of operation; of

work-sheet cl'amping: devices and to produce a Clamp construction bypwhich a work sheet .1 or" less width than 'the platen ma'y be clamped along two ormore edges of the sheet.- 2 Anotherobject of the invention is to produce acombination of work clamping device and-gauging means by which-awork sheet ofless-width 7 than the platen may be gauged and clamped along two or more: edges. l

Witnthe above and other objects in view-, the

invention consists in a mechanism embodying the novel and improved features-constructions and" combinations of parts hereinafter described and particularly pointed: out inthe claims, the adappreciated bythose ekilledinthe art: l a aT-he invention will be clearly understoodlfrom the accompanying drawing illustrating the invention' in its preferred form and the following detailed description of the construction: therein .shown.-.-

The machine comprises a substantially, re'ctangu-g lar platen frame indicated as* a'*whole' at '2 and provided with substantially parallel side bars or is provided jwith thes'usual line space frame mounted upon'the side rails 4jof the platen frame Y for forward and rearward movement. The machine is further Iprovided-withfthe-usual type f carriage supported upon wfrOnt and rear" rails forming'parts 'of the line space frame for movement in letter sp-acingdirectionv and return.

treadle-mechanisml' a p All of the parts above briefly described prefer ably have substantially-the same construction as the corresponding parts of the machine illustrated and described in .said 'Foothorap patent.

It is not considered ne'cessary 'to'di'sclcse in'this 7 application the line space-frame, together with ,its operating mechanismor the typecarriage,

since these mechanisms are sufficiently disclosed in the 'aboverFoothorap patent. ,7

3 In Fig. 1 is illustrated a type barindicated, at

8,'the type bar being-shown in its lowered position for engagingthe type with the work," The platen may. beqsupp'orted and operated'by mech-f anism substantially the zsanie Jas that disclosed in thepatent' to Foothorap No.1,596,420; dated August n, 1926, or rby any'other'suitable mechanism by which it may be moved clamp and release the Work sheets.

'sThe clamping mechanism for clamping the work sheets onth'e platen comprises a clamping strip indicated at 9, secured to the'left .hand platen rail 4' and extending forwardly and rearwardlyvwith relation tothe platen,'this strip being mounted in a groovein the rail and arranged to extend from the rail ashort distance overthe V platen assho'wn in the drawing. This strip-is terminated-"a considerable distance from the front end' of the plateni Justforwardly 'o'f'th'e forward end of the clamping strip 9, the clamp I it plate H1 is mountedfonthejleft rail 4 offthe V platen frameandisarranged to'exetnd laterally over the platen for a substantialdistance towardthe fore-and-aft central line of the plateng' lhe j clamping plate 10 provided with-an attaching 1 is mounted ma groove substantially {the same portion or base I l which in the left handrail f4 in manner as thestrip 9;; To support the'right hand tpo rtiongliigs. 1'and 2, of the clamping plat'e 'iil said portion of the plateis fixed to the upper-end 'Mounted inthe platen frame is the usual sub 'stantially flat platen indicated at lgCarriedfon suitable supporting linksor other supporting'de vices'and arrangedto-b movedyertically' in the plat-en fr'ame bye suitable'manually operated" and controll'e'cl mechanism,,such as a spring-and 1 vertically to r over, as clearly shown in Fig. 4.

v clamping plate 'lfi withits extension of a rod I2 extending from the plate downward- 1y through an opening I in the platen. In order to support the rod; a bar I6 isattached, at its ends, to the under sides of the cross bars 6 of the platen frame and the lower end portion I8 of the rod I2 is threaded and passes through an To hold the rod from axial opening in said bar. movement with relation to the bar, nuts'20 are threaded upon the portion l8o the rod and-are drawn up tight against the bar 16.

The left hand rail 4 constitutes a gauge for locating the left hand edge of a Work sheet in- I troduced between the platen and the clamping plate III. In order to locate the right handedge of said sheet with relation to the clamping plate and platen, a gauge 22 is mounted upon the upper end of the rod l2 between a shoulder on the rod and the clamping plate In. The gauge 22 is 7 preferably circular in cross section and is made somewhat larger in diameter than the rod l2,

the gauge fitting into anenlarged portion of the opening i l in the platen" when the platen is raised. is As shown, the upper end portion 25 of the-rod I2 is threaded and the gauge '22 is'corre spondingly threaded; to fit-on the rod and is V screwed up tightagai'nst theshoulder 24. l The portion 26 of vthe rod is'also'threaded into the The card or other work sheet is introduced betweenthe platenxandltheclamping plate iii dash linesand indicated'at C in 2. When in this position, the forwardv portion of .the clamping strip 9 and theg'portion ofthe clamping plate lilforwardly thereof; willvclamp the vleft hand "marginal portion of the card and the rear marginal portion 2810f the clamping plate [0, will clamp the work sheet forwardly ofthe printing line. In orderto clamp the work sheet plate H3 and the ext-remeehd thereof is riveted l 7 introduced between said clamping plate andthe side rails and a substantially fiat platen mounted for vertical movement in said frame; a clamping 'str-iplattached to one of the side rails of the platen frame and arranged to engage a work sheet at one side of the typing point, a clamping plate fixed to'the' latter side rail and extending from the same over the platen to a point spaced from the other side railand arranged to clamp the work sheet in front of the typing point and an extension on the innerportion of said plate projectingrearwardly from the body of the plate and spaced from each side rail to clamp the work sheet attheother side of the typing point.

2. In a machine of the class described having afsubstantially rectangular platen frame comprising sirie rails and cross bars connecting said side rails and a substantially fiat platen mounted for vertical movement in said frame; a clamping plate attached to one of the side rails of the platen frame and extending therefrom a substantial distance over the platen toward the centralportionof the same and agaugeattached to theinner-portion of'saidplate and extending into the adjacent portion of thelplatenforengagement with theinner edge of a work sheet platen,

l 3. In a machine of the class describedhaving a rectangular, platen frame comprising side rails a substantially in'the position shown" in dot and" to theright ,of the printingpointor line, the v clamping plate 5% is providedw'ith an extension 30 projectingrea'rwardly from the .body' of said u platea's shown in Figs. 1. a1rdl2. This extens on terminates in an edge 32 located some distance to the leftof the gauge 22. Thus when the card or other work sheet is located beneath the clamping plate H3 with its right hand edge inen'gagcment with or relatively close to the gauge 22., the

extension 39 will extend over therighthhand marginal portion of the worksheet, as shown in Fig. 2, and will clamp the isame to the platen when the platen is raised. 5

-The rear edge of the body of the clamping I plate H3 which engages 'a'work sheet in front of a. typing line, is beveled as shown in Fig. 5 to avoid contact of'the type heads therewith.

By means of the clamping strip 8 'and'the v a card or otherwork sheet; introducedrbetween the clamping'plateand the strip and the platen} may be clamped on both sides or and in front offthe printing'or typing line. The adjustable c imes v tion between the lower end of the rod 42 and the. bar-it, enables the vertical position of the righthand end portion of the clampingphtem ,to'be accurate-1y adjusted vertically to iocate the elamping plate parallel with the platen.1
