COPY ATTACHMENT FOR TYPEWRITERS Filed Dec. 10, 1927 2 Sheets-Sheet 2 Patented June 9, 1931 oF FicE V CARL H. MON'SEES, or SALISBURY, MARYLAND COPY ATTACHMENT FOR TYPEWRITERS Application filed December 10, 1927. Serial No. 239,065.

In such institutions as publishing houses, telegraph, railway and public utilities offices, it is desirable and essential that records of all matters be maintained and kept so as to be readily accessible when required. Therefore, recognizing the necessity of making copies of all written matter, the present invention seeks to provide an attachment for typewriters whereby a copy of all work turned out 19 by a machine may be preserved and filed away for future reference.

The invention contemplates a roll of paper a rewinding roll upon which the copy is wound, a supporting frame for the rolls, means for positively operating the rolls and allowing for the difference of diameters due to the unwinding of the paper from one roll and the winding of the paper on the other roll, clamp means for detachably connecting the frame to the typewriter, and roll connecting means admitting of their ready removal and replacement as required.

WVhile the drawings illustrate a preferred embodiment of the invention it is to be understood that in adapting the means to meet specific needs and requirements the design may be varied and such other changes in the minor details of construction may be resorted to within the scope of the invention as 31 claimed, without departing from the spirit thereof.

For a full understanding of the invention and the merits thereof, reference is to be had r to the following description and the drawings hereto attached, in which,-

Figure 1 is a front View of a copy attachment embodying the invention, showing the same applied to a typewriting machine.

Figure 2 is a side view of the parts illustrated in Figure 1.

and table 5.

Figure 6 is a detail view showing the mannor of feeding the several sheets to the'typewriter. I

Figure 7 is a detail view showing two main rolls in addition to the rewinding roll.

Figure 8 is a detail view of a modified form of clamp.

Corresponding and like parts are referred to in the following description anddesignated in the several views of the drawings by like reference characters. 7 The attachment is adapted'to' be applied to any make or model of typewriting machine and in consequence, slight changes will'be necessary to adapt the device to the various styles of typewriters. The attachment includes a supportingframe, clamp means for attaching the'supporting frame to the type .writer, and main and rewinding rolls. The supporting frame comprlses members or bars 1, and clamps at the lower end thereof for detachably connecting the device to the carriage or like part of the typewriter. Referring to Figure 2 of the drawings, the n'umeral'Q denotes the body of a typewriter and 3the' carriage upon which is mounted the platen 4t,

The attachment is mounted upon the carriage 3 tomove therewith. Each of the supporting members 1 is provide'dat its lower end with a clamp which is adapted to be fitted to an end bar 6 of the carriage "3. As'shown" most clearly in Figure5of the drawings, the clamp includes a block 7' and side plates 8. The block 7 is adapted to engage and rest upon a bar 6 and the'side plates. 8 are connected to the sides of the block 7 by so means of'bolts 9, which also serve to draw the plates 8 together and clamp the bar 6 therebetween in a manner to retain the device in proper position. The bars 1 are pivoted to v the clamp at 10, and are made secure in the required adjusted position by means "of bolts 11 whichpass through slots formed in the bars 1 concentric'with'the pivots l0. This is indicated most clearly in Figure 2 oft'he drawings. The numeral 12 denotes the main roll, and 13 the rewi'nding roll. These'rolls are mounted between'the upper ends of the supporting members or bars 1 in a manner for ready detachment and replacement. The numeral 14: denotes a strip-ofpaper of inde-" terminate length which is wound upon the roll 12 and adapted to be unwound from said roll and rewound upon the roll 13. The rolls 12 and 13 are substantially alike, and are adapted to be detachably supported between the members 1. Stub shafts 15 and 16 are journaled to one of the members 1 and are provided with grooved pulleys 17 which are connected by means of a drive belt 18. In this manner both stub shafts are rotated in unison and provision is had for slippage of the drive belt to compensate for difference in diameter of the paper wound upon the rolls 12 and 13. The contiguous ends of the stub shafts and rolls are formed with interfitting parts to insure rotation. These iuterfitting elements preferably consist of a tongue and groove, as indicated most clearly in Figure 3 of the drawings. A spring clip 19 engages a roll and the stub shaft cooperating therewith opposite the oints formed between the abutting ends to maintain them in alinement.

i represents an arrangement whereby an 55 for the copy. Carbon sheets 33 are inter- A barrel 20 is attached to the opposite suporting member 1 and receives a pin 21 which projects to engage the adjacent end of the cooperating roll 12 or 13. A knob 22 is applied to the projecting end of the pin 21 cooperating with the roll 12. A crank 23 is 7 formed upon the projecting end of the pin 21 cooperating with the roll 13. An open coil spring 24 housed within each of the barrels 20 and surrounding the pin passing through the barrel normally exerts a pressure to move the projecting end of the pin in engagement with the cooperating roll 12 or13. The manner of mounting the rolls 12 and 13 admits of their ready detachment and replacement, as will be readily understood.

In the modification shown in Figure 8 the lower end of each of the supporting memposed between the sheets 31, 32 and 14, the duplicate copies being made simultaneously with the original by the well known manifolding process.

Having thus described the invention, I claim:

A typewriter attachment comprising side members, clamps at the lower ends thereof, stub shafts journaled to the upper end of one of the side members, grooved pulleys fast to the stub shafts, a drive belt connecting the grooved pulleys, barrels projecting inwardly from the upper end of the other side member in line with the respective stub shafts, and spring actuated pins in the barrels and projecting beyond the ends thereof and hav ing gripping elements at their outer ends, the inner ends of the stub shafts and pins being'adapted to engage rollers therebetween to support and effect rotation of the rollers as and for the purpose specified.

In testimony whereof I afliX my signature.

bers 1 constitutes an element of the clamp, the coacting elements being pivotedthereto 1 at 25 and consisting of a short 'bar or plate. 7

An open coil spring 26 is interposed between the upper end of the member 27 and the part 1 and presses the lower end of the member 27 inwardly to grip the bar 6 between it and the lower end of the bar 1. An inner extension 28 of the bar 1 forms a stop to prevent downward displacement of the attachment when properly positioned upon a typewriter.

Figure 7 shows an arrangement wherein a second roll 29 is provided to receive a strip 30 of paper, whereby provision is had for a duplicate copy, or said strip 30 may be prepared for manifolding, thereby obviating the necessity for placing carbon sheets to produce a record upon the recording strip or sheet 14. r
