Application filed November 1, 1910. Serial No. 590,118.

To all whom it may concern:

Be it known. that I, ALFRED G. F. KU- nowsnr, a citizenof the United States, residing in the borough of Brooklyn, city of New York, in the county of Kings and State of New York, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specitication.

This invention relates to locking means to "retain paper guiding devices where adjusted along a typewriter platen, and con stitutes an improvement upon a portion of the device disclosed in the application of Frank A. Young, filed October 7, 1910, Serial No. 585,752. In said application a pa per guide and roll are mounted on an arm hinged to a slidable mount or clip, the latter being fitted to a guide rod and the guide being pressed toward the platen by a spring.

I have provided an improved positive lock,

to hold the bracket where adjusted said lock comprisinga dog arranged internally of a barrel that is journaled on the rod and confined between arms formed on the mount, said tooth engaging a rack formed on the rod. A finger piece on the barrel turns the same to release the dog. The rod is oblong in cross section to fit guide holes in the mount, so that the latter may not turn, while said barrel tits on the rod in a man-. her to be capable of rotation thereon. M

Other objects and advantages will herein? after appear.

In the accompanying drawings, Figure 1 is a perspective, showing the invention ap plied to the platen frame of an Underwood writing machine. Fig. 2 is a section through the locking barrel. Fig. 8 is a rear perspec tive of a paper finger, showing the guide rod and rack. Fig. 1 is a cross section, showing the mount locked to the guide rod. Fig. 5 shows the mount released. Fig. 6 is a detail, showing the mount and guide rod.

Types 1 strike a platen 2 on anaxle 3 journaled in the ends 4: of a platen frame, said ends connected by a paper shelf 5. The sheets are drqpped between the paper shelf and platen, and are fed beneath the platen by the usual rear and front feed rolls and 7. After leaving the front guide roll 7, the leading edge of the sheet rises and is caught by a downwardly-extending'finger 8, which conducts the sheet up in front of the platen and under a feed roll 9 running on the platen, after which a rearwardly-extending finger 8 directs the rising sheet backwardly over the platen.

The paper guides and holders are preferably arranged in pairs, one for each side edge of the sheet, the guide fingers 8; 8 and roll 9 being pivoted on inwardly projecting pins 10 carried by arms 11 each pivoted be: tween ears or arms 12, 12, preferably integral with a sliding clip, bracket or mount 13. A spring 1d on the mount bears against a projection 11 formed on the inner end of the arm 11, to press the roll 9 normally against the platen, (Fig. 1). lWhen the arm 11 is swung up out of the way, (Fig. 6) the spring engages a dwell portion 1 1 to hold the guide fingers and roll idle. The mounts 13 are each supported for adjustment to different widths of sheets, on a guide rod 15 extending between the platen ends, said rod passing through bearings formed in the arms 12, 12 and through an aperture 19 in, a steadying arm 20. (forming part of the mount) parallel with the arms 12, 12*. The aperture 17 in arm 12 and aperture 19 in the arm 20 may conform to the-contour of the rod which may be flattened at 16, to prevent the mount from turning thereon. This form may be produced by cutting away opposite sides of a cylindrical rod, so that it will be oblong in cross section, as illustrated.

The .mounts are each positively locked I where adjusted, by an internal-dog 21 projecting from'the inner side of a collar or barrel 22 journ'aled on the cylindrical sides of the rod 15, and confined between the in ner arm 12 and the steadying arm 20. -Said dog 21 is held in engagement with a rack 23 on the rod, by a spring 2 1, coiled around the rod within the barrel, its ends engaging the barrel and the bearing 20 respectively. By pressing forwardly on a finger piece projecting from the barrel up through a slot 26 in the mount 13, the barrel is turned to release the dog 21 from the rack 23 and enable the guide fingers and roll to be adjusted along the rod 15. The releasing pressure on the finger piece causes the latter to bear against one end of the slot 26 and thereby rock the mount slightly forward about the rod (see Fig. 6), to lift the corners 27 of the angular apertures 17 and 19 oifthe rack teeth 23. (which are cut in one corner of the, rod 15), to avoid noise from the teeth in shifting themount along the ioo ' rack,
