TYPE-WRITING MACHINE.

Application filed Jul 2, 1914. Serial at. 848,618.

To all whom it may concern:

Be it known that we, MARSHALL SAR- GENT and Anvil) E. KARLBERG, citizens'o United States, and residents of Indianap- -olis, in the county of Marion and State of Indiana. have invented certain new and'useful Improvements in Type-\Vriting Madeclare the following to be a full, clear, and exact description of-the invention, such as will enable others skilled in the art to'which it appertains to make and use the same.

' This invention relates to improvements in typew-ri t'ing machines and more particu-' larlyfto the universal bar or frame construction and its relation to the mechanism with which it co6perat'es,-one object of the invention. being to reduce the length, force and pounding efiect of the stroke of the key actuated means which control the operation of-s aid universal bar or frame. I

A further object is to provide a universal bar or frame structure which shall-be operated by the key leversin proximity to the fulcrums of the latter and to so mount an engaging or'abutment pad that it may be readily adjusted or renewed.

With these and other objects in view, the invention consists in of construction and combinations of parts as hereinafter set certain novel features forth and pointed out in theclaims. v

In the accompanying drawings, Figure l is a sectional view, partly inelevation, showing a stenographic typewriting machine em-t bodying our improvements. Fig. 2 is a parwith the universal shown in front ele- 4 are detail views.

frame, suitableguiding devices 'being also provided for directing the movements of the paper and inking ribbon between the type and the platen. 1

Av universal frame 11 is mounted on the rod or shaft 7, and comprises uprights l2- 13 connected at their lower ends by a crossbar 14; (which may beltermed the universal barpw- 8e) and; connected at theirnpper portions by a crossbar-'15, which latter may consist of two horizontal arms projecting toward each otherand provided with ears 16 through which a, bolt 17 passes. The ears 16' are spaced apart to accommodate a pawl 18 which is-loosely mounted on the bolt 17 and serves to actuate'the ink-ribbon mecha-" nism when the universal frame is rocked .by the actuation of a key-lever.

'lhelower ends of'the uprights 12- 13 are bent forwardly and extend below the plane of the rod or shaft 7, so, that the universal cross-bar 14 shallbe disposed horizontally unde'uthe key-levers slightly in advance of the pivotal mountings of said key-levers.

A platelt) islocated over the cross-bar 14 and constitutes a holder for a pad 20 to'be engaged by the ground lower faces oredges of the key-levers. The plate l9.is support ed over. the cross-bar 1-'l by means of a plurality of screws 21 which pass -u pwardly through the cross-ban. By means of these screws, the pad may be readily adjusted with-relation to the key-levers, and said pad and its holder may be prevented fromjlat-. 22-

eral -displacen ient by means of screws passing through the uprights of the universal frame and engaging the ends of the" plate or pad holder. Thevarious screws 21- 2; are provided with lock-nuts 23 to insurethe retention of the pad and its holder in the positions to which they may be adjusted.

An arm 2e having a is secured to the lugs 16 of bar of the universal frame,

bifurcated lower end the upper "crossand through'the upper-portion of this arm, a screw 25 passes the head of said screw consti-.

forlnmting the throw of the universal bar when actuated by the key-levers, said universal barbeing returned to and maintained in its normal position by the action of a spring 27. Thekey levers 6 are maintained in and returned to their normal position by its in Tel"- gtistnble a win s 28, mveznents at the "DE-62 z 'i eta-p lmme 1 nepzesse in secure verticnilv anti means for hniding suit;
