TYPE WRITING MACHINE. APPLICATION FILED MAY 2a, 1906.
UNITED STATES A'rnnr OFFICE.-
HERMAN L. WAGNER, OF MOUNT vERnOii, NEW YORK, ASSIGNOR'TO UNDERWOOD TYPEWRITER COMPANY, OF NEW YORK, N. Y., ACOR- PORATION OF NEW JERSEY.
TYPE-WRITING MACHINE.
Specification of Letters Patent.
Patented March 26,1907.
Application filed May 28, 1906. Serial :No. 319,100.
To all whom it may concern:
Be it known that I, HERMAN L.'WA GNEn, a citizen of the United States, resldmg 1n Mount Vernon, in the countyof Westchester and State of NewYork, have invented certain new and useful Improvements in Type- Writing Machines, of which the following is a specification.
' shield over t etype-bar pivots, said'shield coverin the usual slots in thesegment, and move t e shield back out of the way of the type-bars when the latter'are swung u to print. The movement of the shield is e ected by the usual universal-bar frame, to, which thejshield or cover is connected and which moves backward at the latter part of each t e-bar stroke.
the accompanying drawings, e '1 is a perspectiveview of a portion of t 'e wellknown Underwood front-strike writing machine provided with my im rovements,
2 is a perspective view of t e type-bar shield or cover. Fi 3 is a sectional eleva tion of platen, typear segment, and type-' bar. In Fig. 3 a type-bar is shown in normal position, and in Fig. 1 inprinting position.
In said Underwood machine types 1 are mounted upon the forward ends of bars 2, pivoted upon a rod 3, mounted in 'a segment 4, the latter having radial slots 5 to receive the type-bars, and the latter striking against the front side of a platen (5.- The platen is supported upon a carriage (not shown). which runs 'upon a rail 7. T e slots 5, itwi'll be seen, are on the lower or peripheral ed e of the se ment and extend from front to ack 'thereo and are partlyopen at their tops, owing to the formation of a segmental recess 8 in the frontface of the segment-casting immediately above the type-bar guides.v
The type-bar shield is in the form of a segmental sheet-metal flange 9, directly overlyupon a .to receive the type-bars,
sai
its rear edge a ing the slots 5 and normally projecting for wardly, so as to overhang the front face of the segment, Fig. 3, said flange formed on the lower' edge of a curved vertical plate 10, which has a top flange 11 underl' a rib-or anvil 12, formed on the front fac e iifthe segment and adapted to support the type-bars at the instant of printing, Fig. 1.
The parts 9, 10, and 11 all cooperate to prevent access of dust or grit to the type-bar slots 5, whereby the latter are kept clear and constant freedom of action of the type-bars is assured. r
The dust-shield is preferably mounted air of tongues 13', extending forwardly om the usual universal-bar frame 14, said tongues extending through horizontal slots 15, formed in the vertical wall of the segment 4.. The shield may be attached to said tongues by means of screws 16 .and ears 17, the latter detachably secured to the vertical segmental plate 10. *To the frame 14 is fixed the usual segmental universal bar 18 by means of arms 19, formed on the frame and riveted at 20 to cars 21, formed on the universal bar.. The latter is operated on the type-bars and at the completionofeach grmting stroke. of the latter moves backard for the purpose of feeding the carriage by the well-known means. The dust-shield,-
whichis fixed to the universal-bar frame, moves back therewith, so .as'to clear'the typebar when the latter is in printing position, Fig.1. It will be seen that the curved flange v9 may itself be employed as a universal bar and t e segment 18 omitted, the flange 9 being in that case struck by the type-bars and forced back thereby at the last portions of the printing stroke; but the returning-spring and other usual appurtenances of the uni versal-bar frame may be retained. Having, thus described my invention, I claim-- a I I 1. In a type-writingm'achine, the combi nation with a system of type-bars pivoted .below the laten to strike against thefront side thereo of a segment in which the typebars are pivoted, said segment having slots a segmenta shelf pro'ecting forwardlyfrom the front wall of type-bar segment,-asegmental shield overlying the t e-bar' slots and having at an e extending upto said. shelf and directly 'eneath the same, and
auniversal bar mounted in rear of sai typebar segment; and having lugs projecting forwardly through said se ent, and a curved dust-shield in front of t type-bar segment 7 andinounted upon said lugs, and overlying the type-bar slots, and having at its rear edge 1 5 a flange extending up to said shelf and 'ireotly beneath the same.
