Continuation in part of application Serial No. 54,416, filed. October 6, 1915. This application filed July 8,

1916. Serial No. 108,092.

To all whom it may concern:

Be it known that I, BYRON A. SHAMMO, a citizen of the United States, and a resident of the city of New York, borough of Manhattan,

in the county and State of New York, have invented a new and Improved Paper-Fender for Type-Writing Machines, of which the following is a full, clear,'and exact description. This invention relates to typewriting machines or attachments for such machines of the nature set forth in my co-pending application, Serial No. 54,416, filed October 6, 1915, and allowed December 17, 1915, and of which application this is a continuation.

More definitely stated, I provide a device intended to be either an integral part of a standard machine or an attachment to be applied to a standard make of typewriting machine, so constructed and arranged adjacent the upper portion and back of the platen as to receive the upper end of the page or series of sheets being written upon and thereby guide the same well upwardly and rearwardly so as not to roll a second time beneath the platen.

In doing manifolding work, the operator is frequently bothered with the wrapping of the lowermost sheet of carbon paper around the cylinder. Sometimes even two or more sheets will wrap around the platen and by reason of the reduplicating of the carbon impressions, the entire sheet or sheets will have to be rewritten. Under certain weather conditions, even the first sheet (whether a duplicate is being taken or not) will also curl around the platen.

One of the chief objects, therefore, of this improvement is to' apply a device to any standard typewriting machine that will ob viate the difliculties above enumerated in a practical way without encumbering the ma chine or interfering in any manner with the manipulation thereof.

With the foregoing and other objects in view the invention consists-in the arrangement and combination of parts hereinafter described andclaimed, and while the invention is not restricted to the exact details'of construction disclosed or suggested herein, still for the purpose of illustrating a practical embodiment thereof reference is had to the accompanying drawings, in which like reference characters designate the several parts in the several views, and in which the same. I

section of form of'the invention; and Fig. 5 is a Referring now more particularly to the first figures of the drawings, I show a' type of typewriting machine including a platen 10 journaled in a frame 11 and having associated with the frame back of the platen, a paper table 12. This machine also includes a transverse frame rod 13 extending from one side of the frame to the other back of the platen.

vertical transverse section of In the usual operation, the paper is de-' 7 livered. from the platen in an upward direction and the loose ends thereof are apt to curl around the upper and back portions of the platen. In order to prevent this trouble,

I provide a paper fender comprising front 7 and rear panels 14 and 15 hinged together at or around a rod 16 having its'ends secured in a pair ofparallel arms 17 supported on or above the frame in any suitable manner according to the type of machine. in this form of the invention, the rear ends of the arms are pivoted on coaxial horizontal pivots to theupper ends ofa pair of standards l8. The front ends of the arms are fitted with anti-friction rollers 19 adapted to rest upon the ends of the platen, and beneath whichthe platen is adapted to turn in the usual manner with little or no friction. The front panel-14 lies between the front ends of the arms 17 and projects with its front edge close to the upper surface of the platen and thereby the paper will be guided upwardly and rearwardly over the fender. This front edge of the frontpanel may be stiffened or reinforced with a heavy wire or rod 20, whereby sufiicient strength and weight are assured for its purpose. The rear panel 15 of the'fender is adapted to swing upwardly and forwardly around the pivot rod 16, as shown in dot and dash lines in Fig. 2, to give free access to the rear of the platen for introducing the paper, the rod 16 being well spaced forwardly with re- As shownfender is to be determined. After the V 7 standards are secured to the frame or frame bar 13, as above indicated, they will remain fixed'in such position. The arms 17 and the fender plates carried thereby are adapted to swing upwardly and rearwardly, as shown in dotted lines in Fig. 2, in order to gain access directly to the platen or to remove it for any purpose.

Adjustable supports of any suitable character may be provided for the rear fender panel 15 which cooperate with the hinge rod 16 to hold said panel in desired position or at the required inclination for use. These supports are indicated at 23, each comprising a finger having an angularly arranged extension 24: at its lower end fitted frictionally in a transverse hole 25 in the standard to which it is connected. The upper end of the finger 23 may be set forwardly or rearwardly so as to vary the inclination of the panel 15. as suggested in dotted lines in Fig. 2, the side edges of the panel resting upon the turned ends 26 of said fingers.

. In the other form of the invention illustrated in Figs. 1 and 5, the fender is somewhat different in appearance and is shown applied to a different type of machine, but i in the essential characteristics it is quite.

similar to the form previously described. In this modified form, the platen 10 is journaled in a frame 11, to which a pair. of standards 18 may be clamped in any suitable manner. The upper and rear ends of the standards are connected by means of a pivot rod 16, to which the fender plate or panel 15 is pivoted and around which said panel is adapted to swing upwardly and rearwardly to provide free access to the platen. The paper is introduced to the machine beneath the rod 16" and between the panel 15 and the paper table 12. The front portion of the panel 15 is provided with antifriction rollers 19 journaled in shoes 27 slidable forwardly and rearwardly along guideways or keepers 28 secured to the under surface of the panel or fender. The rollers 19 are so positioned that the front edge or lip 14 of the fender will cooperate closely with the platen to receive the paper therefrom and deliver it upwardly and rearwardly along the main fender;

With respect to a typewriting machine having guides adjustable longitudinally of the platen to accommodate narrower paper or cards,it is important that certain portions ofthe main fender panel be cut away to provide access to said guides. I, therefore, provide auxiliary fenders or fingers 29 which project downwardly over portions of the open space and which are adjustable longitudinally of the main fender along a rod 30.

While the device described and illustrated herein is designed primarily and essentially to act as a paper fenderand guide for that portion of the paper already, written upon, it also serves the useful purpose of preventing the unwritten end of the paper from being blown forwardly and becoming doubled or folded beneath the platen, to the annoyance of the, operator. It also prevents the unwritten end of the'sheet from blowing or flopping over above the platen so as to obstruct the operators view of'the work.

I claimr 1. In a typewriting machine, the combination with a frame, a platen journaled therein and means to guide the paper to and around the platen, of a fender to receive the paper as it leaves the platen and deliver it well upwardly and rearwardly, said fender comprising a plate, bracket means to support the plate upon the rim, one portion at least of the fender being movable around its line of support, and anti-friction means for preventing a too great degree of contact between said movable portion and the platen.

2. machine frame, a platen journaled therein and means to guide the paper to and around the platen, of a fender to receive the paper as it leaves the platen and deliver it well upwardly and rearwardly, anti-friction supports for the front portion of the fender upon the platen, and connections between the fender supports and the frame providing for the adjustment of said anti-friction means forwardly and rearwardly.

3. The combination with a typewriting machine including a frame, a platen journaled therein and means to guide the paper to and around the platen, of a fender to receive the paper as it leaves the platen and deliver it well upwardly and rearwardly,

The combination with a typewriting said fender comprising a main panel, a pivot I rod to which the panel is connected and around which the panel is adapted to swing to provide free access to the platen, and

supporting means for adjustably connecting the pivot rod to the frame to vary the relative position of the front receiving edge of the fender panel with respect to the platen.

at. In a paper fender'for typewriting machines, the combination of a pair of stand ards, means to secure the standards in place, a pair of arms pivoted to the upper ends of the standards, a pivot rod extending from one arm to the other, a pair of fender panels pivoted upon said rod, one of said panels being movable in one direction around said rod while the panels are both movable with the arms in the other direction around the arm pivots, and means to limit the swinging movement of said panel around said rod.

5. In a paper fender for typewriting machines, the combination of a pair of parallel arms, pivotal supports for the rear. ends of the arms, a pair of fender panels hinged together upon an axis in front of and parallel to the axis of said arm pivots, one of said panels being movable upwardly and forwardly around its axis, and adjustable means to limit the rearward movement of hinged together on an axis located between V the arms and in front of the arm pivots, and a pair of supports to limit the rearward and downward movement of the rear panel.
