Specification of Letters Patent. 1 Patented. Dec. 26,1911.

Application liled l'uly 18,1910, Serial No. 572,585.

To all t'vhom it may concern: Be .it known that .I, HENRY HERBERT a; subject of the King of Great Brita n,'res1ding at 43 Pelham road, Southsca,

-Portsmouth, in the county of Hampshire,

England, have invented a certain new and useful Combination Device for Type-Writ- :rs, of which the following is a specifica- The present inventfionrelates to a combination device for typewriters and one object of the invention is to provide an easily attachable and detachable accessory device.

which is cheap to manufacture and which .will serve as a receptacle for refuse such as that of rubber, eraser, and paper, such refuse being occasioned by the act of erasing erroneous characters or words from type-written productions while in the machine,'another object being to adapt such a device for use as a hand rest, eraser holder, pencil holder, lockingdevice, protector and advertis ement or sign plate, without appreciably increasing the cost aswill be hereinafter particularly'described.

According t this invention a receptacle formed from sheet metal, wood veneer,

. papier mach, celluloid or other suitable material andis so constructed that it may be quicklyinserted into position insuch relation to the platen, that when erasing takes place the particles of rubber or eraser and paper fall down into the receptacle which thus prevents the said particles from fall into ,or on to pivots, or bearings or other delicate or vital parts of the typewriter;

i As is well known particles of ink eraser as commonly used at the present day contain such matters as are capable of inflicting injury even upon bearings of a hard nature, andfthe use of the device according to the invention not only makesfor cleanliness but actually prolongs the life of the fof a machine In the accompanyingdrawings forming part of this specification ':-F igure 1 is'a perspecti-ve view of a novel device according to this 1nvent1on as seen 'from the .front; Fig. 2 is a perspective view looking into the interior of the receptacle from the rear; Fig. 3 is a rear elevat1on;'-Fi. 4" is a cross section of a typewriting-machlne of the so-called frontstrike variety, showing my device in operative position thereon, and Fig. 5 is a perspective view as seen from the front of a portion to which the novel device is applicable. I r

As is well known the modern tendency is' to construct machines on the front-strike principle according to which the typea on the type bars I) or levers lie normally near to the" keyboard adiagrammatically indicated in Ifig. 4 and which when operated, are against the platen d, Reference to Fig. 5

will show thatthe type-carrying levers b,

are arranged in these machines so as to lie approxlmately 1n the surface of a sem1- cylinder or other segment of a cylinder and Fig. 4 illustrates the manner in which the pivots, e of the levers are located immediately beneath the front portion of the periphery-of the platen (Z so that when an erasure is made upon the paper-sheet f by rubbing the latter where supported by, the platen, the particles of eraser and 'paper fall-down directly upon the pivots e and .other delicate and important parts located immediately beneath. In order to catch and receive all suchrefuse particles and the like the invention provides a receptacle comprising-a body portion 9 which is suitably bent to follow somewhat the curvature of the grille surface formed by the assemblage of type bars or levers b and closed at one end by a segmental end plate h soldered riveted or otherwise suitably fixed to the body portion g. The curved edge ofthe plate h preferably extends beyond the under surface of the portion 9 and referably closely followsthe curve ofthe gr lle constituted by the levers b. Near to the opposite end .of the body portion 6 there may be a shallow upstanding flange j, which acts'asa stop as hereinafter described and which may be cut away. as at k to allow, of'fittmg. flush against theframing in spite of projections upon the latter. The end. plate hmay have its upper edge Z curledor. bent .overso as to 1 thrown upwardly and rearwardly 75 constitute a pencil-holding device and also to offer a smooth harmless and convenient support upon which to rest the hand or wrist when erasing and on its surface toward the interior the plate It may be fitted 'with a loop, or pocket, or clip 'r for supporting and retaining a circular or other eraser s, Thelongitudinal edges of the body portion 9 are conveniently bent over as at m for the purpose of engaging the uppermost side type levers of the curved series and the bent over parts m may be horizontal at and near'the open end of the body portion 9' these horizontal portions merging into downwardly inclined portions at and near the end plate It. The curved edge of the plate It may be shod with rubber as. for instance by securing peripherally thereto arubber strip. In the drawings a rubber strip at, is secured over a portion of the periphery by fixing the two ends of the strip in clips 0 and providing atlange -or seating 0 for the rubberstrip n to lie alongso" asjust to protrude beyond the plate h. i v I The device is applicable for use as folthe periphery of lows:-\Vhen an erasure is to be made the receptacle is inserted into the machine so that its open end enters the space between a segmental .portion'g of the framing and the assemblage of type bai s 'b. The receptacle is pushed in until the flange j comes flush with the framing part g and the eriphery of the end plate h stands upon t e assemblage of type bars 6. The particles which fall during the act of erasing are caughtin the receptacle and prevented from falling.

on to the operative parts. The curled edge Z is situated atjust a convenient height for the hand or wristto be supported thereupon so that it is possible to apply just the requisite pressure which is not easy todo if the hand or wrist is not supported. --It is to be noted that when in position in the machine the side flanges m, take over the uppermost type bars and are supported thereby, When the erasure 1s finished the receptacle is removed and the debris may be emptied there- 'from. w

dust but will also preventthe keys if accidentally knocked from throwing up the type bars and spoiling any work which may be left in the machine.

What I claim and desire to secure by Letters Patent of the United States is 1. In a. typewriting machine,-the combine tion with the machine'fra'me and the typebasket, fof a refuse receiver comprising an open-top receptacle provided with support ing means arranged to engage fixed parts of the machine to hold the receptacle within the type-basket and below the plane of the platen.

2, In a typewriting machine, the combination with the machine frame andthe typebasket', of a refuse receiver. comprising a hollow receptacle open at the top and pro-. vided at its edges with supporting flanges to engage a fixed part of the machine for bolding the receptacle within the type-basket below the plane of the platen.

3.
