Definitions

  • This invention relates generally to copying apparatus, and more specifically to a copy making device for making copies from an exposed matrix by placing a copy sheet in superimposed relation with the matrix to form a copy sheet-matrix sandwich and feeding the sandwich through the device where it is subjected to heat and pressure.
  • Applicants improved copy making device is believed to obviate these and other disadvantages of the prior art devices by providing a heated enclosure for the rollers having a novel compensating system for maintaining the temperature of the rollers within a narrow predetermined range.
  • Applicants device further has a novel electrical system for automatically moving the rollers into pressure engagement when the machine is turned on, and automatically relieving the pressure between the rollers when the machine is turned off. This prevents the formation of a flat on the resilient rollers, which forms following a sustained period of inoperation and which interferes with the proper reproduction of copies.
  • one of the objects of the present invention is to provide an improved copy making device in which a pair of opposed pressure rollers are mounted within a heated enclosure.
  • Another object of this invention is to provide an improved copy making device having a simple, heat compensating system for maintaining the temperature of the pressure rollers within a narrow predetermined range at all times, particularly when making multiple copies.
  • Still another object of the invention is to provide an improved copy making device having means for automatically moving the pressure rollers into pressure engagement when the device is turned on, and moving the rollers out of pressure engagement when the machine is turned off.
  • Another object of the invention is to provide an improved copy making device of simple design and construction, thoroughly reliable and efiicient in operation, and economical to manufacture.
  • FIG. 1 is a perspective view of a copy making device constructed in accordance with a preferred embodiment of the present invention, with portions thereof broken away and sectioned, and other parts eliminated for purposes of clarity;
  • FIG. 2 is a perspective view of the device looking at it from a dififerent angle with a portion thereof in an ex ploded view, other portions thereof broken away and sectioned, and other parts eliminated for purposes of clarity;
  • FIG. 3 is a schematic electrical wiring diagram for the copy making device
  • the copy making device of this invention comprises a base 5, FIG. 1, having a compartmented frame 6 secured to its undersurface for holding sheets of matrix and sheets of copy material.
  • a frame member '7 having side plates 8 is secured to the top of base 5, and each plate 8 has a V-shaped notch 9 for receiving a roller bearing 11 within which one end 10 of a metal roller 12 is journaled.
  • Another bracket 13 is pivotally mounted on a shaft 14 carried by side plates 8, and also has side plates 15 with notches 16 therein for receiving roller bearings 1'7 in which the ends 17' of a resilient roller 13 are journaled.
  • the bracket 13 and its roller 18 are pivotally moved toward and away from metal roller 12 by means of a pair of axially spaced eccentrics i9 (seen best in FIG. 2) mounted on a shaft 21 carried by side plates 8 of fixed bracket 7.
  • the eccentrics 19 are in peripheral engagement with cam followers 22 mounted on a shaft 23 carried by side plates 15 of pivotal bracket 13.
  • the pivotal bracket 13 is urged by a pair of helical springs 24 in a clockwise direction as seen in FIG. 2 for urging cam followers 22 into engagement with the periphery of the eccentric cams 19.
  • Each spring 24 has one end encircling a grooved end of a rod 25 carried in a notch 26 in side plates 15, and its opposite end secured to a threaded bolt 27 (see FIG. 1) extending through a bar 28 carried by fixed bracket 7 and secured to the bar by a nut 29.
  • a feed duct comprising upper and lower plates 31, 32 respectively is secured to fixed bracket 7 by any known means, not shown, for guiding a matrix and copy sheet sandwich into the nip of the pressure rollers 12, 18.
  • An upper guide member 33 (seen best in FIG. 1) pivotally secured by pins 30 to side plates 8 of fixed bracket 7 is adapted in its operative position to receive the matrixcopy sheet sandwich from the rollers 12, 18 and direct it out of the device,
  • the guide member 33 has a projection 3d at each end which is adapted to rest on the periphery of bearing 17 when it is in its operative position.
  • a plurality of upright plates 34, 35, 36, and 37 forming a partial enclosure of brackets 7, 13 and rollers 12, 18.
  • An L-shaped cover member 38 partially shown in FIG. 2 is releasably secured to the plates 34, and 36 to complete the enclosure, which has one notch 39 therein through which plates 31, 32 extend, and a slot 41 in upper plate 38 through which guide member 33 extends. Slot 41 is in register with opening of a housing 4% within which the device is enclosed.
  • a reflector, not shown, is secured to base 5 within the enclosure, and a resistive heating element 42 is secured to base 5 above the reflector for heating the enclosure.
  • insulating material 4-3 in blanket form of any known type is secured to the periphery of the enclosure by clips, not shown.
  • the temperature of the atmosphere within the enclosure and of the rollers 12, 18 is controlled by a thermostat 44' connected to a thermostat probe 44 of known type mounted within the enclosure adjacent the lower plate 32 of the duct (see FIG. 2).
  • the thermostat probe 44 in this position is responsive to the temperature of the lower plate 32, and the temperature of the lower plate is affected by the cooler matrix-copy sheet sari wich as it is introduced into the device. Consequently, as the matrix-copy sheet sandwich 30 is moved over lower plate 32 by the operator, the temperature or" the lower plate is reduced and actuates the thermostat probe 44 to call for more heat before the matrix-copy sheet sandwich 30 reaches pressure rollers 12, 18.
  • thermostat probe 30 to the temperature of lower plate 32 may be controlled by the insertion of a sheet of insulating material 45 between the probe 44 and lower plate 32.
  • the insulating material 45 is releasably held to lower plate 32 by a Spring clip 46 secured to lower plate 32.
  • the drive mechanism for the copy making device comprises a motor 47 secured to a bracket, not shown, mounted on base for driving a shaft 48 through a speed reducer, not shown.
  • Shaft 48 extends through an opening, not shown, in plate .36, and is drivingly connected by a coupling 49 to shaft of roller 12 for driving the roller at a predetermined rotational speed.
  • Another motor 51 similar to motor 47, is also secured to the bracket, and drives a shaft 52 through a speed reducer, not shown.
  • Shaft 52 extends through an opening in plate 36, and is drivingly connected by a coupling 53 similar to coupling 49 to one end of cam shaft 21 for driving same.
  • cam 54 is secured to cam shaft 21 and has a projection 55 thereon for moving a micro-switch 56 between two positions in the power circuit.
  • the device also has an operating switch S movable between off and on positions by means of buttons 57, 58 for connecting an electrical power source to the device.
  • the copying device is then in position for use, and the operator may feed matrix and copy sheet sandwiches 3t ⁇ therethrough for producing copies.
  • the device is turned off by moving the operating switch S to its off position. This action disconnects the power supply from roller drive motor 47, and connects it to cam shaft drive motor 51 through micro-switch 56 which is still in connection with contact 61. Consequently, cam shaft drive motor 51 drives the cam shaft 21 and cams 19, 54 through the remainder of its revolution, during which roller 18 is moved out of pressure engagement with roller 12, and projections 55 releases micro-switch 56 which returns to its normal position in engagement with contact 59, breaking the electrical circuit to cam shaft drive motor 51.
  • a copy making device for making a copy from an exposed matrix by placing a copy sheet in superimposed relation with said matrix to form a copy sheetmatrix sandwich and feeding the sandwich through the device where it is subjected to heat and pressure, the combination comprising:
