COPY-HOLDER FOR TYPEWRITERS.

Specification of Letters Patent.

Patented July 6, 1920.

Application filed. November 24, 1917. Serial No. 208,808.

To all whom it may concern Be it known that I, MILTON EUGENE BLUME, a citizen of the United States, and resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Copy-Holders for Typewriters, of which the following is a specification.

This invention relates to improvements in copy holders for typewriters and has as its principal object the provision of a device, that may be attached to the frame of a typewriter, which will display the copy so it will always be in front of and visible to an operator.

A further object is to provide means for shifting the copy at will; also to display one or more lines of the copy as is desired. Another object is to provide means whereby the copy holder may be folded over the typewriter, when not in use, so as to economize space.

A still further object of the invention is to provide guides for the copy paper which will direct the paper properly into operating parts of the device and also prevent the copy paper from interfering with the typewriter itself.

These and other like objects are attained by the novel construction and combination of parts hereinafter described, and shown in'the accompanying drawings, forming a material part of this invention, the particular features of novelty constitutin the invention being pointed out in the c aims hereof.

in the drawings, in which like figures of reference refer to similar parts wherever they occur: i

Figure" 1 is a front elevational view,

Fig. 2 Same.

Fig. 3 is a transverse sectional view taken on line'33 of Fig. 1, and

Fig. 4 is a fragmental sectional detail of the paper engaging parts, partly broken away in order to show the construction more clearlyyand Fig.5 is a fragmental front elevation of a is a side elevaional view of the thereto. I In the drawings the numeral 10 indicates a pair of opposed feet adapted to be secured to the rear upper part of a lays writer frame. Engaged'therewith by hinge joints 11, are

bent support bars 12, connected by a transverse rail 13, forming a supporting frame for the parts below described, the bars having secured to them horizontal arms 14, in which is journaled an operating shaft 15, provided with a turning knob 16, beyond the arm, while extending between the arms, secured. to the shaft, is a feed roller 17 covered with rubber or similar material.

A compression roller 18 is also mounted in slots formed in the arms, and may be moved to or from the feed roller 17 by hook connections 19, engaged with cams 20, mounted upon a transverse spindle 21, also journaled in the arms 14, and which is turned by operating the lever 22, both the cam carrying spindle and the compression roller being housed in the casing 24, secured by brackets 25 to the support bars 12, in which is also secured a guide plate 26, turning angularl'y toward the front, which is adapted to direct the paper 27 to the feed roll. A curved paper guide 28 is hinged by the pin 29 to the lower edge of the casing 24, and serves to guide the copy paper projecting from between the rollers and to keep the same from interfering with parts of the typewriter and also as a screen to cooperate with the screen 37, below described, to screen from the view of the operator all of the copy except that portion thereof being transcribed. Springs 30 are engaged with the supporting frame and the extendin ends of the compression roller so that t e latter is normally held against the feed roller.

Also supported by the support bars 12, by means of brackets 32, is a curved plate 35, the ends 36 of which are turned toward the front, and engaged with the same isa screen 37 operable vertically with relation to the support plate by means of racks 38 engag ing with spur pinions 39 secured to a shaft 40, rotatably mounted in bearings &1, the shaft having an extending knob 42, so that by turning said knob the screen 37 is caused to move parallel and uniformly, so as to disclose at will one or more lines of the mat ter to be copied. l

The upper ed e of the; screen 37 is bent backwardly to mm a paper guide 37 as shown in Fig.3. p In order torotate the paper feed roll '17, a ratchet wheel 45 is secured to the shaft 15, and engageable with it is a pawl 46, normally pressed forward by'a spring 47 secured to one of the support bars 12, the pawl having an extending pin 48 by means of which it can be withdrawn from engagement with the ratchet. This pawl is pivotally engaged at its lower end with the top of a bar 50, slidably engaged in a bearing 51 formed with the adjacent support bar, and is pivoted at its lower end to a link 52, having a plurality of slots 53 in its lower end, engageable with a pin 54 set in the end of a lever 55, fulcrumed at 56, and having at its outer end a button or key 58 by means of which the lever may be depressed, it being normally held in a raised position by the spring 59, which is of sufficient'tension to actuate the feed roll when the lever is released.

Journaled at the top of the support bars 12 is a spindle 60 having secured at its ends disks G1 and an operating knob 62, said disks containing openings (33, through which pins may be passed from the arms 64, said arms carrying at their extremities a rod 65, upon which is secured a plate 66 formed with a turned lower edge (57, re ceptive of a thin book such as is used by stenographers, the leaves of which are held against the plate by a slide 70 having a longitudinal slot 72 through which the copy is disclosed, and which is held in any desired adjustment on the plate by means of the flat springs 73, carried by the slide in contact with the back of the plate opposite to the guide edges 74, thu. )ermitting the slide to be adjusted as desire In Fig. 5 I illustrate an important feature of my invention, showing that all the copy in the copy-holder is screened from view with the exception of that portion that is actually being copied. Also that the line of matter 100, that is being copied, is held at all times in vertical alinement with the line being written by the typewriter, or, in other words, with the striking point of the type against the platen of the typewriter as shown at 101.

It will be obvious that the element 28, while serving as a guide for the copy paper, also acts as a screen for the copy on that portion of the copy paper that projects invariably beneath the feed and compression rollers, and that said element 28, and the screen 37 together eflectually screen all the copy except that portion of the same that is intentionally exposed to be copied.

In operation, the feet having been secured on a typewriting machine, the support bars are extended as shown and locked in position by the slotted sliding plate 76, which engages with a stud or screw heads 77 when in use, or which permits the structure to be folded over the machine when not required.

Paper is inserted in front ot the plate 35 and the knob 16 operated to feed the same desired, after which the button or key 58 may be actuated producing the same re suit. The plate 37 is then adjusted to show one or more lines of the copy, or if a copy book is used, the support plate (36 is turned forward and used in the manner indicated.

From the foregoing it will be seen that a convenient device for holding the copy has been disclosed, and that one or more lines may be shown as is desired, and that the copy can be moved in a convenient manher by the operator.

It will also be seen that the copy is in the best possible position to be viewed by an operator and that the same may be readily attached to any machine.

Having thus described my invention, what I claim as new and desire to secure by Let ters Patent, is:

1. A copy holder comprising a supporting frame, a feed roller and a compression roller mounted in said frame, a fixed guiding member extending upwardly from a point adjacent, the meeting line of said feed and compression rollers, and an adjustable guiding and screening member dis )osed in front of said. fixed guiding mem er and having its bottom edge a short distance above the said compression roller, a rack secured to said screening and guiding memher, a pinion engaging said rack, and means whereby said pinion may be rotated.
