PAPER'FORM GUIDE Filed 001;; 5, 1962 FIG.3.
IN VENTOR Cecil William von't Velg United States Patent 3,1t'37,fi36 PAPER F'Uiatai GUEDE Cecil W. vant Veid, seas l ew Hampshire Ave, Apt. 315, Silver Spring, Md. Filed Get. 5, 1962, Ser. No. 223,566 2 Claims. (Cl. 225-196) The present invention relates to paper form guides, and more particularly to a paper form guide applicable to high speed printers.
The primary object of the invention is to provide a paper form guide that can be readily and easily attached to high speed printers, and which will guide the paper forms continuously into their proper position when the high speed printer to which the paper form guide is attached is in operation.
A further object of the invention is to provide a paper form guide which is easy and inexpensive to manufacture.
For illustrative purposes, but with no intent to unduly restrict the application or scope of the invention, the paper form guide is shown in the drawings as applied to a 1403 Printer, which is manufactured by the International Business Machines Corporation.
The efiiciency and advantage of this invention will become apparent in the following specification when considered in the light of the attached drawings, in which:
FIGURE 1 is the perspective View of the invention located in its proper position on the IBM 1403 Printer.
FIGURE 2 is a vertical medial cross-section of the invention and the IBM 1403 Printer.
FIGURE 3 is a frontal view of the invention located in its proper position on the IBM 1403 Printer.
Referring now to the drawings in detail, wherein like reference characters indicate like parts throughout tl e several figures, the reference numeral 10 indicates generally a paper form guide constructed in accordance with the purpose of the invention. However, the paper form guide 10, shown in the drawings, although preferred, is
not necessarily the only form of embodiment of the invention.
The supply of continuous form paper 1 flows in the direction indicated by arrow an at top of FIGURE 2, by arrow dd in center of FIGURE 3, and by arrow ee at top of FIGURE 1. If the paper form guide 16 were not attached to the IBM 1403 Printer 2, the form paper 1 would how in the direction indicated by arrow bb at center and to the left in FIGURE 2. The form paper 1 would consequently pile up in Area A, which is formed by the glass door 14, the stacker guide 4, and a section of the IBM 1403 Printer 2. With the paper form guide 19 attached to the IBM 1403 Printer 2, the paper form guide 19 will enable a continuous flow of form paper 1 to proceed in its proper direction and arrive between the stacker guide 4 and the steel backing 3 of the IBM 1403 Printer 2, as shown at bottom of FIGURE 2. Arrow cc, at bottom of FIGURE 2, indicates the flow of the form paper 1 when leaving the IBM 1403 Printer 2.
The fiat surfaced section 12 of the paper form guide 10, shown in center of FIGURE 1, has two slots 6, each of which is inserted behind the head of a metal screw '7 located on the pivoting cover 5 of the IBM 1403 Printer 2, as shown at upper left of FIGURE 2. When cover 5 is raised, as shown by 5a in FIGURE 2, the flat surfaced section 12 of the paper form guide pivots along with the cover 5, the position of the paper form guide being i 'a concavely shown in dotted lines and indicated by the reference numeral $12. When this occurs, the two perpendicular sections 8 of the paper form guide 163, as shown in FIG- URE 1, remain in a perpendicular position between the stacker guide 4 and the steel backing 3 of the IBM 1403 Printer 2. This continuous perpendicular position of the two perpendicular sections 8 of the paper form guide it results from the fact that the two perpendicular sections 8 are attached to the flat surfaced section 12 of the paper form guide it by means of two hinges 15, each hinge 15 is attached to one perpendicular section 8 of the paper form guide it The pivoting of the paper form guideiti on hinges 15 prevents the paper form guide 10 from pressing aaginst any form paper 1 located between the paper form guide it and the steel backing 3 of the IBM 1403 Printer 2.
The two perpendicular sections 8 of the paper form guide it} each have curved upper ends 9 to guide the form paper 1 when it flows over the curved top of the IBM 14-33 Printer 2, as indicated by the curved arrow aa located at top of FIGURE 2.
The two curved upper ends 9 of the two perpendicular sections 8 are attached together by means of a horizontal section 11. With the paper form guide 19 attached to the IBM 1403 Printer 2, the stacker guide 4 is still able to operate as originally designed. The lever 16, FIGURE 3, can still raise or lower the stacker guide 4 to its maximum high and low positions.
Having thus described my invention, I claim:
1. A guide for guiding the leading edge of a supply of continuous form paper in a high speed printing machine of the type employed as an output medium in data processing systems wherein the continuous high speed flow of form paper in moving from the input to the output portion of said machine must change direction through an arcuate path so as to operatively enter an output paper form channel defined by a flat backing means and. an output guide means spaced therefrom comprising in combination: at least one elongated member having a straight portion adjacent to and overlying in spaced relation said flat backing means and extending from said output guide means in a direction opposite to the direction of flow of said form paper so as to define a paper form channel operatively aligned with said output paper form channel, said elongated member terminating in a curved free end portion extending beyond and at least partially overlying said arcuate path of said form paper so as to present curved guiding surface to the leading edge of said form paper passing through said arcuate path whereby said leading edge of said form paper will be guided into said paper form channel defined by said straight portion of said guide and said backing member and thence into said output paper form channel without manual arrangement of said form paper in said paper form channels, and mounting means associated with said printing machine operatively mounting said elongated member.
2. The structure defined in claim 1 wherein said mounting means includes means pivotally supporting said guide.
