TYPE-WRITING MACHINE Specification of Letters Patent.

Patented'June 9, 1908.

Application filed June 22, 1907. Serial No. 380,196.

To all whom "it may concern:

Be it known that I, ROBERT J. ORR, a citizen of the United States, residing in New York city, borough of Manhattan, in the county of New York and State of New York, have invented certain new and useful Improycments in Type-VVriting Machines, of which the following is a specification.

This invention relates to typewriting machines, and particularly to means for gaging and alining the side edge of the sheet-of paper as it is being introduced into the machine and passed forwardly around the platen.

One of the "principal objects of the invention is to facilitate the adjustment of said side gages or guides, as well as the front paper-guiding fingers, to accommodate different widths of sheets tobe used.

In carrying out this feature of invention, I

couple the side guide directly to the front guiding finger, so that both may be adjusted together along the platen,-and so that'when either one is adjusted to 'the right position, the other is necessarily adjusted to a corresponding position.

The front paper'guiding fingers of the well known Underwood typewriting machine are mounted by means of brackets upon a rod extending along the platen at the rear thereof, and are independently swiveled on said rod so as to be turned up away from the platen. In carrying out my invention, I mount the side guides on the same rod, and couple them to the front guiding fingers, (or to the brackets that carrysaid fingers), so that the adjustment of either the finger or the side guide which is coupled thereto, insures a corresponding adjustment of the other of the coupled memben In theaccompanying drawings, Figure 1 is a plan View ofthe platen frame of the Underwood typewriting machine showing my im-- provcments applied thereto' Fig. 2 is a perspective fragmentary view of a typewriter p aten and paper table, showing the improved paper-guiding device. Fig. 3is an end view,

showing the parts in normal positions. Fig. A

4 is a view similar to 3 but showing the papenguiding finger raised from the platen.

igs. 5 and 6 are plan and side elevations, re

spectively, of the improved side guide. Fi s.

7 and 8 are a side View and plan, respective y,

of the paper-guiding finger and the bracket therefor.

The usual platen 1 is ournaled in a frame in the machine.

2 having an inclined paper table 3. The ends 2 of the platen frame are connected by a fixed rode, having on its under side a longitudinal groove or key-way 4 Swiveled on said rod 4 and extending forwardly therefrom is ,a. bracket 5, theforward end of which is bent at right angles, to form an ear 6. To thisear is attached a springy finger 7, curved forwardlyand, down around the front of the platen, for guiding the paper and pressing the same against the (platen. Carried on said paper-guiding finger is the usual pressure-roller. 8. From the bracket 5 a bar 9 extends along rod 4, and is bent up to form an car 10,- said rod 4 passing through both said ear and the rear end ofthe bracket 5. The usual roll or lever 12' is pressed by a bowed spring 11 into said key-way 1*, thereby pressing the roll 8 against the platen.

Mounted against rotation on the rod 4 and extending rearwardly therefrom,- isan arm 15 for guiding the paper at its side edge, said arm carrying at its rear end an inclined papersupporting flange 16, which lies close to the surface of the inclined paper table 3, the inclination of said flange agreeing substantially with the inclination of the paper table, and the side guide and flange just clearing said table. A key 17 on arm 15 fits in the keyway 4 in the rod l, to prevent the arm from turning. Although the arm 15 and bracket 5 are coupled together, stillrotatio n of the bracket onv the rod l'independently of the arm 15, is. permitted. I provide the arm 15 with acurvedslot or slots 18, to receive the shank of screws 20 each having a nut 21, the

fiat edge of the nut engaging the rod 4, to

prevent the nut from turning. The screws are tapped into holes 19 in the brackets 5.

The arm 15 is slightly offset as at 22 whereit is coupled to the bracket 5, so as to aline with said bracket, Fig. 1, and thereby facilitate the'alining of the side edge of the apcr The limits of the a justment of the guide and bracket along therod 4, are determined by collars-23.

In Fig. 3 the bracket 5 is shown in its lowermost position, with the roller 8 ofthe' paper-guiding finger 7 in normal position on the platen, and in Fig. 5 the same arts are shown, but with the paper-guiding nger re-- leased or swung up away from 'thepla'ten.

Having thus described my invention,,I claim:

1. In a typewriting machine, the combination of a platen, a platen frame, a rod fixed 4. In a typewriting machine, the combinain the platen frame above the platen, an arm tion of a platen, a platen frame, a rod having mounted on said rod against rotation and a key-way and fixed in the platen frame ends extending rearwardly therefrom to support slightly above and in rear of said platen, a and guide the paper at its side edge, and a i bracket swiveled on said rod, apaper-guiding paper guiding finger rotatable on said rod finger attached to said bracket and extendand extending forwardly therefrom and curving forwardly, the bracket at its oint of ating down around the front of the platen; said tachment to the paper-guiding nger being arm and finger being coupled together for offset to approximately the width of the finsimultaneous adjustment along said rod. ger, an arm also mounted upon said rod and 2. lnatypewrlting machine, the combinaextending rearwardly therefrom, said arm tion with a platen frame and a rodfixed in having a paper-supporting flange at its rear said platen frame, of a spring-pressed paperend, and also having a spur or key fitting the guiding finger journaled upon said rod and key-Way in said rod to prevent rotation of. extending forwardly therefrom, a side guide said guide thereon, and a curved slot formed mounted upon said rod and extending rearin said arm, means extending through said 0 wardly therefrom and having a spur or key slot for coupling the arm to the.bracket, said to fit a key-way in said rod to prevent slot permitting the rotation of the bracket on rotation of the side guide on the rod, and the rod independently of the arm, and the also having a curved slot, and means enarm and bracket being adjustable together ga ing the curved slot to couple the side along the rod; said arm being offset at its guide and the paper-guiding finger together, point of coupling with the bracket so as to the paper-guiding finger being rotatable on l aline with said bracket.
