Application filed November 25,1927. Serial No'. 235,541.

This invention relates to typewriting machines which are used for typing stencils, and

. particularly to machines provided with frames in which stencil-cards are inserted in a flat and moistened condition. The present improvement relates to devices for shielding the machine'for the purpose of protecting the slots in the segment, the ribbon-shield and operating arm, the type-bars and the linkbearings from water or other liquids'used in 'moistening the stencils before inserting them in the machine and dirt from the stencils. Heretofore, one of the main objections to the I stencil-typing machines has been the clog- 1 ging up and sticking of the typewriter-parts, due to the'rust and dirt caused by the wet stencils, so that it has been essential to clean the typewriter thoroughly very frequently in order to keep it in good working order. The

2 necessity for the costly cleaning of the machine so frequently will be greatly eliminated by providing the machine with shielding devices in accordance with the present invention.

According to the present invention there is provided a longitudinal shield at the rear of the segment-bar in a position so that moisture or dirt of'any kind which drops from the stencil-card will fall on the shield, and from there into'an inclined gutter which directs such matter into a removable receptacle out side the frame of the machine, The shield itself is formed with a gutter extending over the universal bar and other parts of the typewriting machine in a manner to divert the fluid from these parts, so that it will flow out. either side'thereof into the inclined gutter Both the shield and inclined gutter are positioned where they will not interfere in any manner with the operating parts of the type- .writing machine. Q

The shield and gutter in accordance with the resent invention are formed so as to bereadlly attached to the machine without altering any of the parts thereof, but by'securing them m place by utilizing existing sdrews which secure other parts of the machine in place. *f y x Other features and advantages will hereinafter appear.

In the accompanying drawings, Figure 1 is an isometric view. of therear portion of'a tfiewriter, with partsebroken away to show t e present invention; appl ed vFigure 2 is a rear elevational view of the typewriting machine. in which the present I invention is incorporated, parts being omitted and broken away.

Figure 3 is a-vertical sectional view taken on line 33 of Figure 2;

This invention is illustrated as applied to an Underwood standard typewriting ma= chine suitable for the handlingof cards, such asnsed in certain'types of addressing -machines. The machine includes a platen 11 mounted in a carriage 12, reciprocably mounted upon'a frame 13 in the usual manner. Th1s machine is provided with a stencilcard-carrylng frame 14 for carrying a stencil-card 1.5 in flat condition, in typlng position in front ofthe palten 11. The usual type-bar-segment 16. is-provided on which type-bars 17 are pivotally mounted at 18 and operated by means of levers :19 and 20. causmg the type-heads 21 to strike along the printing line of the platen. The typewriter is provide and escapement-mechanism generally designated at 23, with which the ribbon-vibrator with the usual universal bar 22 c 24 is connected for raising the ribbon 25 to the printing point when a type-key is depressed. The ribbon may be silenced for cutting stencils by a mechanism (not shown)i such as disclosed in the patent to Cook, No.

926,050, dated Junie 22, 1909. The escape- .ment-mechanism 23 and other parts are mounted on standards 26 extending upwardly.

from a base 27 mounted on the rear base-portion 28 of the frame 13. The parts thus far described are all standard in the stencil-cutting typewriting machine.

The present invent on mcludesa shield 29, I

which is secured by means of screws 30 to thesegment-bridlgle 31 and slopes'downwardly therefrom wit the middle portion of the lower edge bent upwardly to forma gutter 32 above the universal bar 22, extending between it and the typewriter case-shift-bar 33. The shield 29 extends laterally beyond the ends of the type-bar-segment a suflicient distance so that it will extend under the stencil-card, 15 from one extreme end position of the card-frame travel to the other.

vIt is customary to soak the stencil-cards and position them in the card-holder in a moistened condition.v The shield 29 is ef-..

fective to catchany'drippings, small particlesof fiber or other matter from the stenoils and to divertthe same awayffrom the various underlying parts of the typewriter so that the drippings will fall into an inclined gutter 34 beneath the shield 29. The gutter 32 is effective to direct such matter to either side ofthe universal bar and ribbon-vibrating mechanism. a I

The gutter 34 is provided with a closed upper end 34 and extends from the left-hand end of the shield 29 downwardly in an inclined direction to a position beyond the right-hand portion of the frame 13, and on the outer end: 35 thereof is a removablymounted receptacle 36. A ring 37 is secured to the end 35 of gutter 34 and is provided with bayonet slots 38 forreceiving pins 39 on the receptacle 36. This receptacle 36 can be emptied by occasionally removing it from the ring 37 by a slight turn therein, and, after it is emptied, it can be returned and fastened in place again by a similar operation.

, The gutter34 is provided.with rearward horizontal extensions 40, 41 and 42, which are secured to similar'extensions on arms 43 and 44 extending upwardly from a base-member 45, which is secured above the escapementbase 27 by means of screws 46. The extensions 41 and 42 are separated sufiiciently so as not to interfere with the back-spacing link 47 of the typewriting machine, which extends upwardly through an opening 48 provided by the spacing between the extensions and formed in the upper portion of the arm 44.

Variations may be resorted to within the scope of the invention, and portions 'of the improvements may be used without others.
