TYPE-WRITER ATTACHMENT.

Specification of Letters Patent.

Patented Nov. 19, 19 18.

Application filed July 9, 1917. Serial No. 179,410.

To all whom it may concern:

Be it known that I,- O'rro H. Knnnonn, a subject of the Emperor of Germany, re-

' siding at Los Angeles, in the county of Los Angeles and State of California, have in vented a new and useful Type-Writer Attachment, of which the following is a specinew paper to be copied from the original.

Another object is to provide means by which the original paper is shifted automatically with the paper shifting mechanism on a typewriter.

Another object is to hold the original paper free from and above the paper written on the typewriter and copied from the original paper. 7

Another object is' to provide shifting mechanism on the attachment similar-t0 the shifting mechanism on the typewriter so-as to allow the shifting of the original paper above the newly written paper in accordance with the advancing of the newly written aper separate from the shifting of the newly written paper, shifted by the mechanism of the t pewriter.

Another ob ect is to cover the writing of the original pa r except for a suitable number of wor so as to make it easy to compare the words ofjhe original paper with the words of the newly written paper.

Another object is to providescales near the words of the original paper and similar scales near the words of thenewly written paper so as to automatically check up the letters, figures and spaces of the original paperwith the letters,'figures and spaces of the newlywritten paper to the minute fragmentary perspective view Other objects will appear from the following and accompanying papers.

In the drawing Figure 1 is a front elevation of an assembly of my device.

Fig. 2 is an end elevation of the device in Fig. 1.

Fig. 3 is a fragmentary line 3-3 of Fig. 1.

Fig. 4 is a fragmentary elevation of the frame with roller engaging mechanism.

Fig. 5 is a detail side elevation of the sectional view on spring for holding the reading plate andchecking plate in a desired position, to be secured to the main frame 5.

F 1g. 6 is a fragmentary perspective view,

illustrating the engaging of the lower ends of the main frame over the shaft of the platen, such shaft and platen as well as a of a typewriter being shown in dotted lines.

5 designates the main frame suitably shaped at its lower end 6 to engage over the shaft 7 of the main roller 8 in a. typewriter 52, and also constructed to allow the attachment of suitable extra plates 9 to make the frame applicable to the different makes of typewriters. In Fig. 2, the lower end 6 of the main frame is formed hooklike to hook over the shaft 7 of the typewriter-roller 8 from the front, the extension end 10 projecting toward the rear of the typewriter having a suitable number of threaded holes 11 for screws. by which in combination with the small plate 9'tl1e main frame 5 is secured to the typewriter. The plate 9 is provided with slots or notches 12 allowing a shifting in a suitable direction to bring the slot, notch or cut out 13 close to a rod 51 or suitable screws on the typewriter thereby locking the plate and there'- with the main frame 'to the typewriter, as will easily be understood, there being always rods or screws rearwardly of the main roller or platen within the frame work of the typewriter. And it will also easily be understood that other means may be used as long as the frame 5 can thereby be held on the typewriter in a similar manner.

A rod, as indicated at 51 in Fig. 2, is on certain types of Underwood typewriters a short distance behind the platen parallel to mswrltioss mo ls or a reading plane '23 is swingsbly mounted i some film roller 15.

main frame 5. To disengage the holding rollers 15 and 16 from the main roller 8 for the, purposedescribed above, the disengaging frame 35v is lifted until the catch 39 engages the frame 35 holding theframe in this suspended position. The catch 39 is swin'gably mounted on the main frame 5 by the pin plate 40.

As soon as the catch is released, the disengaging frame 35 is pulled down into its engaging position in relation with the main roller and the holding'rollers 15 and 16 by the springs 19, as described above.

If the reading and checking plates are: not desired close to the rollers, they can be set by suitably shaped spring members45, havingsuitably shaped recesses 43 and 44, allowing a setting of the plates from the lower position 41 to the upper position 42 just as desired.

Such spring members can. easily be at-- tached to the frames close to the edges of the reading and checking plates, as will easily be understood. 7 a

Having thus described my invention, I claim:

1. In a copy checking device of the class described a frame having means for removably engaging the shaft near both ends of the main roller or platen of a typewriter and projecting from such engaging points radially in relation to the platen, both ends of the frame having slots extending from near the engaging points to a suitable extent radiallyjn relation to the platen, and copy holding rollers turnably disposed within the frame and engaging with the slots for sliding movement radially in relation to the main roller or platen, the longitudinal axis I typewriter.

of the copy to the axis of the platen.

holding rollers being. parallel 7 2. In a copy checking device of the class described a stationary frame having means for removably engaging the shaft'near both" endsof theplaten of thetypewriter andhaving slots from near the engaging points extendingto a suitable extent radially to the platen'forming the stationary frame for the copy checking device, copy holding rollers having shafts dieposedthrough the slots in the stationary ame, and a movable frame having slots parallel to the slots in the stationary frame for slidingly engaging over the shafts on the-cop holding rollersadapted to hold the copy olding rollers out of engagement with the platen of the 3. In a copy checking device of the class described a frame comprising two parallel guide members each having a guideway parallel to a guideway in the other, copy-holding rollers turnably'and slidingly mounted in the guideways of the, frame, the frame having 'also means for removably engaging a typewriter at any'suitable point for bringing the guideways in the frame into radial relation to the axis of the platen of the typcwriter, the guideways being of suitable length and design to allow oneof the copyholding rollers to rest on the platen of the typewriter arallel to the platen and a1- lowing anot er roller to rest on the first vnamed roller parallel to the firs't' named roller the guideways also adapted to allow a shifting of the copy-holding rollers to a suitable extent to be out of engagement withthe platen. I

In testimony whereof I have hereunto set I my hand at Los Angeles, California.
