To all whom it may concern Be it known that 1, JOHN E. MoLu a citizen of the United States, residing at 'Wausan, in the county of Marathon and Stat of Wisconsin, have invented a new and usei'vl. Paper-Holder for Type-Writers, of which the following is a specification.

This invention relates to paper holders for typewriters and is more particularly a division of an application for United States Letters Patent filed by me on August 3, 1908, Serial No. 446,677, renewed December 12, 1911, Serial No. 665,378.

Heretofore it has been the practice'in order-to hold envelops, or sheets of paper of diiferent sizes, in proper position on the platen, to provide paper holding clips on the earria e and adjacent the ends of the platen, said c ips being shiftable toward or from each other so as to lap the side edges of the envelop or sheet of paper to be written upon. The adjustment of these clips has required considerable time and in some machines it has been found that should the operator fail.

to return the clips to their extreme positions at the sides of the carriage, when wide sheets of paper are being used, the type will strike the clips and-be injured thereby. Furthermore the clips are so located as to be difficult to reach quickly.

One of the object-s of the present invention is to provide means whereby paper of different widths can be properly held against the platen at the point where it receives the impact from the type,-this holding device re- :quiring no adjustment and being so located that it can be easily thrown into or out of clamping position.

A further object is to provide a device of this character which not only serves to hold the paper in place but can also be used as a straight edge when it is desired to rule a line upon the paper without removing the paper from the platen.

With the foregoing and other objectsin view which will appear as the description ;proceeds,the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood uat changes in the precise embodiment of the invention herein disclosed can be made Within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown. In said drawings: Figure 1 is a front ele-- vation of a carriage having the present improvements combined therewith. Fig. 2 is a section on line AB Fig. 1, one of the positions of the paper holder being indicated by dotted lines. Fig. 3 is a section on line C-D Fig. 1. Fig. 4 is a bottom plan view 7 of one end portion of the carriage.

Referring to the figures by characters of reference 34 designates the end plates of the carriage and in which are journaled the end portions of the shaft of the platen 33, said end plates being connected at their lower front corners by a longitudinal bar 35 and other rods or bars 36 connect the said end plates so as thus to form a rigid frame for the support of the platen. A roller 37 is journaled on the bar 35 and is adapted to travel on a suitable track, not shown. A

. clip such as shown at 43 maybe attached to the front bar 35 for the purpose of preventing the front of the carriage from lifting up off of the track on which the roller'37 may be mounted.

Arranged under the platen 33 and extending throughout the length thereofare rollers 50 and 51 journaled at their ends in levers 52 each of which is pivoted, between its ends, to one end of a bar 53. These bars 53 are pivotally connected, as at 53, to the end plates 34.and are connected by a plate 54 which constitutes a paper guide. This plate extends downwardly close to the roller 51. Each lever 52 carries, between the journals of the rollers 50 and 51, an anti-friction roller 54 engaged by a spring 55 which tends to maintain the rollers 50 and 51 yieldingly in engagement with the bottom portion of the platen.

A s'tud 201 may be extended laterally beyond one end of the paper guide 54, this stud projecting over a cam 202 which is pivotally mounted, as at 203, upon 'one of the end plates 34 of the carriage. A finger piece 204 extends laterallyfrom the cam so that the said cam can be easily shifted. The camis so shaped that, when it is moved in one direction, it will push upwardly on the stud 201 and tlius cause the paper guide 54 and the two'bars 53 to swing about their pivots 53', thereby shifting the levers 52 and the rollers and 51 away from the platen 33. An apron 5T is'movably connected to the bar 35 at the front of the carriage and is held yieldingly in contact with the lower portion of the platen by springs 58 connected to the bar 3 I A rod 66 extends longitudinally across the front portion of the platen and. is supported at each end by a lever 67 fulcrumed on one of the end plates 34. Each lever has a thumb piece extension 68 at its upper end while a roller 69 is carried by the lower end of the lever. A spring 70 is fastened to each end portion of the bar 35 and projects into the path of the adjacent roller 69. The construction is such that the paper holding bar 66 may bemoved toward or from the surface of the platen to hold the paper thereto or to release it vtherefrom. This movement is participated in by the rollers 69 which engage the spring fingers 70 and ride over the same, and these spring fingers snap back behind the rollers when the bar 66 is in engagement with the paper and press it against the end plates 34. Furthermore when the bar is moved away from the platen a sufiicient distance to release the paper, the springs 70 will again snap back of the rollers 69, thus holding the parts yieldingly out of operative position. The spring fingers 70 thus constitute a yielding lock for the bar 66 in both of the positions to which. said bar may be shifted.

, It is to be understood that paperor envelops of any width equal to or less than the length of the platen 33 can be inserted between'the guide 54 and the platen 33 so as tozbe engaged by the rollers 50 and 51 as well as by ithe platen. Thus by rotating 3 the platen, the paper or envelop will be guided between the platen and the apron 57, the'end' edge of the paper being moved upwardly across the front portion of the platen. Whenthe bar 66 is pressed forwardly away from the platen, as indicated by dotted lines in Fig. 2, the paper upon being shifted by the platen will pass between the platen and the bar 66.- By then pressing the finger pieces 68 toward the end plates 34, the bar 66 can be caused to snap against the paper and push it against the platen, thereby holding it smoothly ,on the platen. The action of the bar 66 will .be the same no matter what may bethe width of the paper or'envelop used. By shifting the cam 202 so as to elevate the stud 201, the bars 53 can.

be shifted on their pivots 53 so as to move the rollers 50 "and 51 away from the ,platen 33, thereby to permit the paper or envelop to be pulled freely from position ion the platen. i

It is to be tacts with the paper above the line on which the impression is received and thus will not interfere with the-view of the charactersas printed. Furthermore the said bar 66 can be used as a straight edge whenever it is desired to rule a line upon the paper.

What is claimed is 1. In a typewriter the combination witha carriage and a platen mounted for rotation thereon, of members pivotally mounted on the carriage, a paper guide connecting the understood that the bar 66 con-- members above their pivots. and movablewith the members, levers fulcrumed between their ends upon the members below the pivots of the members, rollers. journaled at their ends within the levers, and yielding means engaging said levers for .holding the rollers in engagement with the platen and for holding the guide yieldingly in normal position.

r 3. In a typewriter the combinationwith a carriage, and a platen mounted for rotation thereon, of'members pivotally mounted between their ends on the carriage, a plate constituting a paper guide connecting the members' above their pivots and movable with the members, levers fulcrumed upon said members below the pivots of the members, a

pair of rollers journaled within the levers, yielding means engaging the levers between the rol ers for holding said rollersin contact with the platen, and coiiperating means upon one of said members and the carriage for shifting the members to move the rollers out of engagement with the platen.

4. In a typewriter the'combination with a carriage, and a platen.v mounted for rotation thereon, of bars pivotally mounted between their ends, on the carriage, a paper guiding plate constituting a connection between and. movable'withthose portions of the bars above their pivots, levers fulcrumed upon the bars below the pivots thereof, rollers journaled at their 'ends within the end portions of the levers, yielding means engaging the levers at points between the rollers for holding said rollers in contact with as my own, I have hereto afiixed my signathe platen, a projection upon one of the bars, ture in the presence of two witnesses. and a cam movable into engagement with the projection for shifting the bars Land I JOHN MOLLE' guide plates about their'pivots to 'move the Witnesses: I rollers out of engagement with the platen.
