Definitions

  • the present invention relates to manifolding apparatus for typewriters, calculating machines and other such writing apparatus and. comprises carbon shifting means for employing the same sheets of carbon tissue several times, said carbon paper being interleaved between continuous strips of papen.
  • One object of the present invention is to provide a typewriter manifolding device. having a frame connected with the platen roller carriage: and a carbon tissue. holder slidablys mounted on said frame for movement: to and fromthe platen roller and a: power accumulating device con-- nected with said holder soas to accumulate power when the: holder is moved toward. the: platen roller and. deliver itagain during the oppositely directed movement of the holder in which thepull of the power accumulating device on the. holder will not tend to displace. the carbon sheets relative to the strips. of paper contacting; the platen roll.
  • a further object of. the invention is to provide: a typewriter'manifolding; device: of: the said kind; the manipulation. of which is: very simple. and requires aminimumof t'ediousmovements by the operator.

  • Fig. 4 is another-"embodiment of the invention shown in the same-manner asFig-l 2 and Fig. 5' is one of the side plates from the inside;
  • FIG. 2 is the platen roll carriage of the writing machine and3 the platen roll itself.
  • 4- is a frame support consisting. of rods connectedtothe stationary parts oi the writing machine i and carrying a guide rod 5 upon which the frame 6 of the manifolding attachment is slidably supported.
  • the lower partot theframe 6 is fixed to the platen roll carriage of the writing machine and the upper part carries side plates 1 supporting a power accumulating device 8 and guidingfor the paper and other parts of the manifold ing device described the following part of the description in connectibn with-two different cin bodimentsofthedevicet 4
  • Fig. 2,6 is a frame and L0 guides along the sides thereof guiding the ends H of? the carbon tissue holder.
  • the carbon tissue holder carries apin [2- on which are suspended. rules L3 each or which carries a sheet of carbon paper of. which only one is shown. Suchlrules l3 with carbon tissues it are interleaved between strips l5 and 16 of writing paper ofi which only two; strips are shown the strip l6 being. the one onwhich direct typing will be made and-the strip-1 5 being the one which will. contactthe platen roli

  • the holder II is, however, connected by a string or tape 3
  • the roller 32 is rotatable on the shaft 20 but connected with it by means of a spring 33 so that the roller, spring and shaft constitute a power accumulating device in which power will be accumulated when the holder H is moved forward pulling the string or tape 3
  • 34 is a rod over which the paper strips are passing. The rod 34 is fixed into the side plate 1.
  • Behind the roller 32 another roller 38 is rotatable on a shaft 3! (Fig. 5) mounted on the lever 33 fixed upon a pin 42 or a shaft reaching from one side plate 1 to the other and passing through journals in the side plates. On the pin or shaft 42 a hand lever 35 on the outside of the plate 7 is fixed.
  • the lever 36 is connected with the side plate by a spring 43 tending to keep the shaft 31 and roller 38 against the roller 32.
  • the pressure between the two rollers 32 and 38 can be released by depressing the lever 35.
  • the two-armed lever 39 having on at least one end a stop 4
  • the roller 32 has a milled surface or is covered by some friction giving material, e. g. rubber.
  • some friction giving material e. g. rubber.
  • the lever 35 On operating the embodiment of the invention illustrated in- Figs. 4 and 5 the lever 35 will normally not be depressed and the rollers 32 and 38 will press against each other with the paper strips between them.

  • a typewriter manifolding device having a frame for mounting on the platen roll carriage of a typewriter a transfer sheet holder slidably mounted on said frame for movement to and from the platen roll and a power accumulating device connected with said holder so as to accumulate power when the holder is moved toward the platen roll and deliver it again during the oppositely directed movement of the holder, a rotary member for engaging directly by friction that strip of the paper which in its further movement will directly contact the platen roll, means for transferring power from said rotary member to the power ac-- cumulating device during movement of the paper toward the platen roil, means for providing friction involving pressure for said strip with respect to said rotary member, and means for releasing the friction involving pressure between the strip and the rotary member.
  • a typewriter manifolding device having a frame for mounting on the platen roll carriage of a typewriter, a transfer sheet holder slidably mounted on said frame for movement to and from the platen roll and a power accumulating device connected with said holder so as to accumulate power when the holder is moved toward the platen roll and deliver it again during the oppositely directed movement of the holder, a rotary member, a roller for pressing against said rotary member at least that strip of paper which in it further movement will directly contact the platen roll, and a shaft on which said roller is mounted, said shaft being movable to such a degree that the friction between said strip of paper and said 6 rotary member ceases, said rotary member being rigidly connected with said power accumulating device.
  • a manifolding apparatus for use with a type writer having a platen roll carriage, comprising a frame for mounting on said carriage, a transfer sheet carrier mounted upon said frame for reciprocatory motion thereon, means for storing energy connected to said carrier for accumulating energy during movement of the carrier toward said platen roll and for releasing the energy thus acquired during the car ier movement away from the platen roll, a first rotary member disposed on the end of said frame r mote from said platen roll for engaging directly by friction that one paper strip which in it further movement will directly contact the platen roll, means operatively linking said rotary member and said energy storing means, means including a second rotary mem ber disposed adjacent first rotary member for releasably pressing at l ast said one paper strip toward said first rotary member, normally inoperative means for releasing said last named means from its pressing position, and means responsive to said releasing means upon the operation thereof for limiting the movement of said carrier toward the platen roll.
  • said releasing means comprises a first lever for moving said second rotary member
  • said movement limiting means comprises a second lever having a movement limiting projection and a mechanical linkage to said first lever, said projection being disposed in the path or movement of said carrier upon operation of said releasing means.
