Specification of Letters Patent.

Patented Jan. 5, 1909.

' Application filed May 1a, 1903. Serial No tb'KGIB.

To all who'mit may concernf Be it known that I, BURNHAM C, STICK- NEY, a citizen of the United States, and resident of Elizabeth, in the county of Union audState of New Jersey, have invented oertain new and useful Improvements in Type- Writln Machines, of which the following is a' specliication.

hls invention relates to the paper guid Zing devices of typewriting machines, and

paper after it leaves the printing point, such forinstance as illustrated in my U. S. Patent No. 658,931, dated October 2nd, 1900; and its object is to guide the leading edge of the paper away from the platen at the proper tune, soas to avoid liability of the paper fouling with certain parts ofthe paper- I guiding and other carriage mechanism. 20...

My invention consists in. certain combina- .tlons of devices and features of construction, as W111 be hereinafter set forth and particularly pointed out in the concludingclaims.

In the drawings foming part of this specification, Figure 1 is a perspective view of a front adjustable paper guide of the class described in said patent. Fig. 2 is a cross section of a paper carriage of a front strike writing machine, showing my improvements applied thereto. Fig. 3 is a perspective view of a stripper for guiding the paper away from the platen. Fig. 4 is a front view of the paper carriage.

In the several views, like signs denote like parts.

The paper carriage comprises sidebars 1 and 2, jomed by a rear bar 3, which runs upon; suitably/"supported balls't. A platen .s-is mounted upon an axle 6 which is journaled in said side bars. Behind the platen is mounted a paper shelf 7, from which the aper is fed and guided around. the platen h y pressure rollers 8 and 9 and a deflector 101, A scale 11 at the front side of the platen-is supported at its ends upon arms hese are pivoted upon the forward ends platen and have springs Exte'nding longitudinally of the platen and'ii'nounted thereover and in rear of a of fixed arms 13, which extend for-.. Wardly" beneath the 14;;for pressing the scale against the platen.

axis, is a bar 15, secured at its ends by screws 16 in the side bars 1 and 2 of the carriage. The bar is longitudinally grooved at 15, and sleeves 17 are splined thereto so as to be independently adjustable therealong. From the outer end of each sleeve an arm 18 extends forwardly directly over the platen upon its delivery side; and at its forward end the arm is bent inwardly longitudinally of the platen at 19; and u on this free end is laterally mounted a flexible finger 20, which is curved to suit the platen and extends forwardly and downwardly in front thereof, at its lower end' overlapping the platen scale, and. at its u per end approximating the bar 15, and flaring upwardly so as to make a passage for the paper over the bar. The latter 1s provided with a spring 21 for pressing the paper fingers against the platen or the paper thereon.

Between flanges 22 formed upon each sleeve 17, I mounta stripper'23, which may be formed of sheet metal, and consists of a cylindrical body portion 24 formed loosely around the sleeve 17 so as to pivot thereon, and a forwardly and downwardly inclined stripper portion 25, whose forward end may rest slightly upon the platen, the weight of the stripper being preferably sufiicient to keep it in contact with the platen. The stripper which is confined against endwise displacement by the flanges, extends between the bar 15 and the platen, and is adjacent to the upper end of the paper guiding finger 20, the latter overlying the former, as seen at Fig. 2, and the stripper and finger cooperate with opposite sides of the paper to give positive direction to the movement of the paper. The strippers also extend inwardly from said fingers towards each other, as'at Fig. 4.

The stripper preferably Widens from its front portion to its rear portion, the edge connecting said portions being oblique, as

at 26, thereby assisting in stripping the paper from the platen.

In operation, the paper is fed in b the rollers 8 and 9 and guided bythe de ector 10 and the platen. scale 11, from which it feeds between the fingers 20 and the platen and passes onward over the bar 15, emerg- ,said arms, and a pair 0 -ing between" the arms 18 and through the mounted upon saidbar for. adjustment therealong, and a stripper pivoted upon said paper-guidingdevice. ,Y,

3. In a typewriting machine, the combination witlj a=platen, of a bar extending along the p aten, a paperuiding device supportedhpon said bar fbr ad ustment therealong, said paper-guiding device extending forwardly from said bar directly over the platen and including a finger which extends partly around the platen, and said bar being arranged relative y to the platen andthe'guide *so that the paper may feed between said finger'and the platen and pass and means. adjustable onward over the bar,

with said papery-guid ng device for stripping the paper from the-plateff 4; In a typewriting machine, the combination with a platen, of a bar parallel therewith and arranged above the platen, a device adjustably mounted u on said bar and extending forwardly therefrom directly over the platen for guiding the paper rearwardly over said bar when it has passed the printing point," and a gravity-operated stripper connected to said paper-guiding device so as to be adjustable therewith.

- 5. In a front strike typewriting machine,

the combination with a platen of a paper guide curved to suit the platen and terminating at its lower on in front of the platen and extending upwardly and rearwardly over the platen, a bar parallel with the platen and arranged at the rear end of said guide, means extending rearwardly over the platen for supporting said guide adjustably upon'said bar, said supporting means being so a-rranged'that the paper may pass under the guide and overthe bar, and a pivoted stripper between the-bar and the platen.
