IEMMET M. INGERSOLL, OF

' RATION OF ILLINOIS.

, OF CHICAGO, ILLINOIS, A ooRPo-' PAPER-GUIDE FOR TYPE-WRITING MACHINES,

.' To" all whom it may concern: "Be it known that I, EMMET M. INGERSOLL, residing at 'Woodstock, in the county of McHenry and State of Illinois, have invented certain new and' useful Improvements in Pa er-Guides for Type-'Writin Machines; and do hereby allowing is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

This invention relates to improvements in paper-guides for the carriages of type-wri ting machines by which the advance ed e of a sheet of paper when inserted into t e machine is guided around the platen from one feed or presser roller to the other. 7

The object of theinvention is to provide a device for holding properly in place the intermediate portion 0 a paper-guide of the eneral character mentioned In constructions where the length of the guide is such (as in an extra long carriage) that the guide cannot well be made sufficiently stifi or rigid to prevent the de from bending or flexing and wherein th d central part of the guide tends to shift out of its proper position in relation to the resser-rollers and the platen.

improvement is herein shown as applied to the carriage of an Oliver typewriting'machine; but it may be adapted to other machines where the same general features of construction of the pa er guiding and holding devices used in the liver typewriting machine are resent.

As shown in the awings, .Fi re 1 is a 1 front elevation of the carriage 0 an Oliver type-writing machine, showing my improvementap liedthereto. Fig. 2 is a cross section of t e carriage. Fig. 3 is a perspective view of the holding device, showing a part of the pa er-guide in dotted lines.

- As s own in the drawings, A designates as a whole the carriage of an Oliver t e-writing machine, A the platen thereof, and A A A the resser-rollers by which the paper is 'ded about the platen and by which it is ihgld roperly in'place against the platen during "t e printing 0 eration'. Said carriage comprises in genera terms end plates a a and (t upon the of the letter-spacing mechanism.

shield located at the front of e platen and A A and by which the advance mar in of a sheet of paper which is being inserte' into a machine Is guided as it asses from the lower to the upper presser-ro er. The saidfront resser-rollers are mounted in aframe comprising end pieces 0 C and a longitudinal connecting-bar O,'whioh extends be tween and is connected at its ends with said end pieces. Saidbar C"'is connected with to swing at its lower margin toward and from the platen. The'shafts of said resser-rollers are rotatively mounted in the 11 per and lower ends of said end pieces C of th' removably mounted in the carriage of the machine by means ofstuds c c, projectinglater ally from said end pieces, and enter forwardlyopening notches in the end plates va, a, of the carriage-frame. The arts thus described are held in place and are attached at their lower ends to the car-' riage and bear at the upper or free'ends against the ends of the guidelate B, the

springs permitting the guide-p ate to yield thic ess of a number of sheets The construction of said frame and the manner of mounting the same and the rollers and guide on the carriage are substantially the same as shown in the prior United States Leton the 11th day of February, 1902,v and need Patented June Application filed June 8,1904.

WOODSTOCK. ILLINOIS, ASSIGNOR TO THE OLIVER "TYPEWRITER COMPANY between the upper and lower resser-rollers said end pieces by means permitting it to pressed toward the platen by means of leaf-springs E E, which .ters Patent to Knapp, No. 693,033; granted f J not be further described. Such otherparts 1 of the carriage illustrated which constItute no part of the present im rovements are not herein described', but are t ejusual parts of an Oliver type-writing machine.

The improvements constituting the present invention-consist of a device or devices for supporting or holding pro erly in place the intermediate portion of the guide-plate B with respect to the platen uudto the when upward or outward pressure is appliedthereto, as when inserting a heavy sheet of paper or a number of sheets of paper into the carriage, thus resulting in pressing the guideplate B, upwardly away from the lower presser-roller in advance of the n'iargin ol' the entering sheet, thereby seriously interfering with the proper passage of the sheet or sheets of paper around the platen. in order to remedy this defect, I provide an attachment con sisting of an arm F, which is attached at its lower end to the carriage-lrainc and extends upwardly to and engages the central part of the supporting-bar in a manner to prevent the central part of said bar and the plate attached thereto from bending or flexing outwardly. Said arm also made of yielding character to permit the central part of the guide-plate to yield bodily outward with its ends and the end pieces C C to which it is pivoted when a thick sheet of paper or a number of sheets of paper are inserted into the carriage. Said arm is thereby adapted to act with the springs E E to hold the guideplate as a whole pressed toward or adjacent to the platen. Said arm F in the instance illustrated consists of a fiat leaf-spring which is afi'ixed at its lower end in any suitable manner to the longitudinal member a of the carriage-frame and is engaged at its upper end with the bar C, whieh carries the guide late B in a manner to prevent said her from both bending outwardly and rising. As herein shown, said arm is provided at its upor end with a hook-shaped portion f, which.

The arm is attached at its rower end to the longitudinal member-of the carriage, in the instance illustrated by means of a l'ieaded screw f extendingthrough a slotted opening f 2 in the lower end oi" the armand into the carriageframe. member. Said slotted opening enables the arm to be vertically adjusted with respect to the carriage-frame in fitting the same to the machine. if a single supporting or' holding arm 1? be employed, it is lo cated midway between the ends of the guide plates B;'b ut more than one arm may be used, in whicl'ievent they are so disposed as to receive e,"qually the stress brought upon the guide'tending to displace the same. It is obvious that the same general results will be obtained if the arm be made otl'ierwise than of spring 1n'aterial-as, for instance, tl 1e part F may be made rigid and yield ingly connected with the earriage frame by a spring connection.

I claim as my'inventi0n- 1. The combination with a paper-'carria e, b connected at its ends with the carriage-frame and springs pressing the swinging margin of the guide toward the platen, of an arm'af fixed to the carriage-frame and engaging the paper-guide at a point opposite-its pivotal axis and between the-ends of said guide to prevent the central part of the letter from flexing or bending outwardly.

2. The combination witl'i apapsr-carria e, platen, a longitudinal paper-guide pivota 1yconnected at its ends with-the carriagedrame to afford movement one margin of the guide toward and. from. the platen,- and springs acting on the ends of" the guides to hold the guide as a whole adjacent to the platen and also to yieldingly press the swinging margin thereof toward the platen, of a yielding or spring arm mounted on the can riage-frarne and engaging the guide at a point opposite its pivotal axis and between the ends of sis-id guide to hold the central part of the letter from bending orfiexing outwardly.

3. .he combination witha pa er-carriagei, platen, a longitudinalpaper-gu1de pivotally connected at its ends 1th the carriageframe and sprin ing the swinging margin of the gniidev the platen, of an arm at l lXfll tO the carriage-fm1ne and engaging the guide at a point opposite its pivotal axis and between the ends of said guide to prevent the central pa rt of the latter fronrfiexing or bend ing outwardly, said arm being so attached to the guide as to also prevent the samefrom bending er flexing upwardly.

4-, The combine-hon with apaper-carriage, platen, a longitudinal papefeguide pivotally connected at its ends with the carria -trams to aflordmovement of one niargin of the guide toward and from the platen, and

in effect, a rocb-shait, to.

springs acting on the ends of the guides to hold the guide as a whole adjacent to the platen and also to yieldingly press the swingingmargin thereof toward the platen, of a yielding or spring arm mounted on the carriage-irame and having interlocking engagement with the guide between the ends of the latter to hold it from both outward and upward fiexure.

5. The combination with a paper-carriage, a platen and a longitudinal paper-guide which is connected at its ends with the carna e-frame, of a yielding or spring arm attached at its lower end to the carria edrame, and provided at its upper end with a hook which engages the central part of the guide in a manner to prevent the same from rising.v

- 6. The combination with a paper-carriage, a platen, upper and lower resser-rollers at one side of the platen, a frame movable toward and from the platen in which the shafts of said Presser-rollers are rotatively mounted, and a guideplate located between said presser-rollers and connected at its ends with said Presser-roller frame, of a holding-arm attached to the carriage-frame and connected with the guide intermediate the ends of the latter to prevent the central part of said guide from bending outwardly and rising.

In testimony that I claim the foregoing as my invention I affix my signature, in presence of two witnesses, this 15th day of April, A. D. 1904.
