entree stares KW FFIC rnunimn nn, or STAVANGER, NORWAY TYPEWRITEB AND LIKE MACHINE Application filed May 21, 1931, Serial No. 538,984, and in Norway April 121930.
I have made applications in Norway on the 12th April, 1930. Patent not yet grant-' ed; Sweden on the 9th April, 1931, Denmark, on the 11th April, 1931, Germany on the 11th April, 1981, and Great Britain on the 13th April, 1931. V
The present invention" relates to typewriters and has for its object to provide an automatic device for the insertion of envelopes into a typewriter. According to one construction a pile of envelopesis arranged on a support adapted to receive a'ieed movement, and the envelopes are removed one by one from the pile by means of endless transporting means, are carried bythese means around the platen of the typewriter, and after the completion of the typing are removed from the platen and conveyed to a suitable point where they are discharged.
One construction embodying the features of the invention is illustrated by way of e2;-
ample in the accompanying drawing, 1nv
which Fig. 1 is a sectional elevation ofthe im-\ proved device taken on line AB of Fig. 2,
Fig. 2 is a plan of the device corresponding to Fig. 1, and i Fig. 3 is a detailed cross section on line CD of Fig. 1, showing the pile support and the manner of its mounting on the machine.
Referring to the drawing, a pile containing a. suitable number of envelopes 1 is carried upon a supporting plate 2 adapted to be fed by .springs 3 which hold the supporting plate pressed against a frame a, slots 5 being provided in the plate 2 for the reception of the springs and for guiding the plate 2 along the springs. The frame l is provided upon its longitudinal edges with flanges 1a in which are adjustably mounted lugs 13. These lugs 13 carry by means of bearing members 12 a shaft 11 on which are rotatably mounted rollers or pulleys 6. Over the pulleys 6 and the ends of the platen 7 of the typewriter run two bands or belts 8 carrying a a number of thin cross bars 9. The pulleys 6 are preferably provided with flanges 10 for guiding the endless belts. Alternatively, the pulleys may be provided with projections engaging openings in the belts for the purpose of guiding and driving the latter.
The envelopes 1 rest with their forward ends against a stop plate 15 which is provided with a'downwardly bent portion 16. The latter portion 16 rests on the paper apron 17 of the typewriter and serves as a slide for the envelopes. The plate 15 is provided with two clips 18 which grip the surfaceof the paper apron 17 and together with the portion 16 serve for attaching the device to the machine.
To insure that the cross bars 9 of the transporting. device shall-always slip under the closing flap 19 of the envelope, a plate 20 is provided which forces the said cross bars down, just before theyreach the flaps of the envelopes. The plate 20 is so shaped as to leave the closing flaps loose or free.
The operation is as follows: p
-V Vhen the platen of the typewriter is turned, the belts are moved in the direction of the arrows andone of the cross bars 9 slips under the closing flap 19 of the topmost envelope and during continued rotation of the platen carries the envelope around the platen into the position for typing. Upon further rotation of the platen the endless belts are further moved and the cross bars carry the envelope out of the platen, whereupon the envelope is discharged at the rear of the device.
It will be understood that in the foregoing description the term typewriter is meant to include any similar machine employing a platen, and the term envelope is intended 85 to cover articles similar to envelopes and intended to be inserted intothe machine, Details of construction may be modified in various ways without departing from the scope of the invention. For instance, instead of employing two belts provided with cross bars asingle broad-belt arranged on rollers might be employed.
