Application April 23, 1949, Serial No. 89,348

4 Claims.

My invention relates to an improvement in an attachment for a duplicator machine which consists of a postcard feedbox.

It is a feature of my invention to provide a feedbox for duplicator machines which produce copies principally from stencils or from a system known as the spirit or direct process.

It is a further feature of my invention to provide a card feedbox which will hold a supply of cards in correct position for positive feeding to a duplicator machine and which may be positioned on the duplicator machine with little adjust ment, thus doing away with the adjustment and positioning of the ordinary guides used for work in the size of letters and legal material. My device is so constructed that it may be placed in operating position without the use of connections or tools. My device is used principally with postcards but it may be used with cards of any size. Heretofore postcards had to be fed one at a time by hand to the duplicator machine, or a change of the large guides on the machines had to be made, which change does not prove adequate.

It is a further feature of my invention to provide a card feedbox which may be positioned on a duplicator machine without disturbing the setting of the guides provided with the machine which may be set for letter or legal sized paper.

It is an additional feature of my invention to provide a card feedbox which has resilient retaining posts which prevent more than one card from being pushed into the machine at one time. I also provide risers upon which the cards are positioned. These risers cause the cards to lay in the feedbox ina cupped position which facilitates forcing one of the cards from the feedbox at atime. r a

It is also a feature to provide projections or locating guides on the bottom of the feedbox to hold the same in rigid position on, the feed table of virtually any type of duplicator machine.

These features, together with other details and objects, will be more clearly defined and set forth in the following specification and claims.

In the drawings:

Figure 1 is a perspective view of a duplicator machine with my card feedbox placed in operating position thereon.

Figure 2 is a perspective view of my card feedbox.

Figure 3 is a bottom view thereof.

Figure 4 is a plan view of my card feed box positioned as illustrated in Figure 1, showing the feed arm of the duplicator machine in operating position over the same and the card partially removed from the card feedbox.

Figure 5 is an enlarged sectional view on the line 55 of Figure 4.

Figure 6 is a bottom view of an alternative form of adjustment for my card feedbox.

My card feedbox A is composed of a bottom portion I0 which has secured to the sides thereof the longitudinal side wall portions I I. The partial end wall portions I2 are formed on the rear ends of the feedbox A projecting inwardly fromthe side walls II. tray A is open.

Adjacent the rear end of the side walls II I provide the openings I3 formed in the side walls I I and which are adapted to receive a portion of the resilient cylindrical card retaining members I4 which partially project through the openings I3. The card retaining cylinders I4 may be made of rubber or any suitable material. The openings I3 extend the full width of the side walls II except for a portion of the side wall II at the top edge thereof. The casings I5 are secured to the outer surface of the side walls II and retain the cylindrical card retainers I 4 in proper position in the openings I3. The distance between the inner The front end of the feedbox surfaces of the rataining members I4 is slightly.

less than the width of the card B desired to be used with a feedboxtray A. In addition the retaim'ng members I4 are maintained at a slight angle with relation to the side walls II as illustrated particularly in Figure 5. The angle of the retainer members I4 facilitates the placing of a large number of cards between the members I4 and also the moving of the cards from the feedbox tray A by means supplied from the ordinary duplicator machine C. The cylindrical retainer members I4 may be inserted into position from the bottom of the casings I5 through an indentation formed in the bottom It with the upper end of the retainer I4 butting against the upper edge of the opening I3.

The risers I5 are formed in the bottom I0 adjacent the rear partial end walls I2 and the resilient card retaining cylinders I4. The risers- I5 cause the card B to lie in a cupped position which facilitates moving the cards from the feedbox A as particularlyillustrated in Figure 5 of the drawings.

I also provide 2. depending lug I6 which is centrally located on the bottom I0 of the feedbox A. The lug I6 is adapted to fit Within the groove I! found on virtually all duplicator machines and the same positions the feedbox A laterally on the feed bed I8 of the duplicator machine C. The depending rear side lugs I9 are secured to the bottom I0 and adapted to fit the transverse slot 20 found in the feed bed of virtually all duplicator machines. The lugs I9 maintain the feedbox longitudinally upon the feed bed I8 of the machine A.

The lugs I6 and I9 may be adjustable as are the lugs 2I and 22 illustrated in Figure 6 by providing the long angled portions 23 thereon and having formed therein the slots 24. The set screws 25 are positioned within the slots 24 and screwed 1n- 3 to the bottom I thereby allowing complete ad justment of the lugs 2| and 22 for duplicator machines which are not universal in construction.

My card 'feedbox ,is used in "the following manner:

The cards B are placed within the feedbox A so that the side edges are in contact with the partial end walls 12, and the under side of the bottom card rests on the bottom and the risers l5, which tend to maintain the cards in a cupped position. To facilitate the cupping of the cards the cards may be cupped slightly as they are placed in the feedbox A tightly fit between the retaining members M. The cards B are also, when inserted in the feedbox tray A, positioned againstfthe'partial endwalls l2. The'members i4 tend to .''hold the cards within the'feedbox A under raslight tensionbut'which cards B may be removed. therefrom by the :movement' of the feed arm D as it contacts the upper card by means of the gripping members '26 as secured. thereto. With the cards B in cupped position as illustrated in Figure 5' only the lower corner edge of the card contacts the retaining members 14. Thus the contact'of the cards B with the retaining members M is positive but only on theunder lower corner thereof and not along the "full edge of the cardx-as would be the case if the cards werefiat and .not cupped. In this way cards, although positively held, are more easily removed than if the oards were in aflat position.

The: card feedbox A with thecards positioned therein ashereinbefore-described, is then placed on thebed I 8'of the machine'C so that either the lugs lil and IE or the lugs 2| and22 fit within the slots I1 and. 20. With the feedbox .A thus positioned, the machine C is then set in operationgandthe' feed armD'with the gripping members" 26 :is caused to contact the upper cardand move it'. toward the stencil roll of the'machine where animpression is made on the same. The card is then carried from'the stencil roll to a receiving receptacle such as 21.

'The feedbox A may be made'of a size to handle the Government penny postcard for the printing of the same with a duplicator machine. My device fills a long felt need for a retainer which would quickly, efiiciently and easily hold postcards forprinting on a duplicator machine. It is obvious that my feedbox tray may be made of a size to handle any given sized cards.
