  • Our invention relates to a printing device
  • the object of our invention is to provide a printing device of that kind in which the types are caused to rollagainst the paper.
  • Fig. 1 is a sectional view showing the position of the type-wheel before printing
  • Fig. 2 is a sectional view showing the position 25 of the type-wheel, as the typeirolls on'the paper;
  • Fig. 3 is a sectional .viewshowing the position of the type-wheel, after the printing hasbeen done;
  • Fig. 4 is a front view of the machine. Some 30 parts have only been partially designated'or have been removed to facilitate the understanding of the drawings.
  • Types 1 are mounted on type-wheel 2, which is joumalled on support 4 above pivot 3.
  • the typewheel turns about its pivot 3 synchronously with the motion of the register cards past a contact device on the tabulating machine.
  • a toothed wheel 6 is secured by means of rivets 5 to type-wheel 2; this toothed wheel 6 meshes with a toothed wheel '1 itself in mesh with toothed wheel 8, which, in turn, meshes with gear 9 provided on main driving shaft 10.
  • This main shaft 10 rotates in an anticlockwise direction.
  • Toothed wheels 7 and 8 are pivoted to type-carrier 4 about pivots 11 and 12 respectively.
  • Typewheel carrier 4 is pivoted at 13 and 14 with two intermediate links 15 and 16 55 respectively, which links are pivoted to the frame about pins 18 and 17.
  • typewheel carrier 4 rests through its projecting part '19 upon a stop 20 on frame 21.
  • lever 28 provided with rack 58, the lever release 29, springs 30 and 31, intermediate piece 32 and 70 magnet 33.
  • The, type-wheel carriers can be moved independently from one another because they are mounted at a distance from each other which is smaller than the width of the magnets; some of the magnets 33 are mounted one below N the other, as shown in Fig. 4; but with each type-wheel carrier 4, there corresponds only one magnet 33.
  • Return bar 34 extending over the whole width of the printing device acts on all type-wheel 80 carriers, and when moved, returns all type-wheel carriers back into their initial position. Said bar34 is secured to arm 35 which is attached to fixed frame 21 through pivot 37 about which it can turn. Am 35 is moved by means of cam 38 85. mounted on main shaft 10 in such a way that F cam 38 strikes against a roller 39 which is fixed through pivot 40 to arm 35. Return bar 34 tends always to be brought back into its initial position (see Fig. 1) by means of spring 41. This spring 00 isattached to arm 35 by means of pin 42 and to v the fixed frame by means of pin 36.
  • Shaft 10 of the printing device and therefore also typewheel 2
  • Shaft 10 of the printing device rotate synchronously with the main shaft of the tabulating machine, and also synchronously with the passage of the cards past a contact device.
  • intermediate link 16 is provided with an elongated slot 51 in which axle 14, which is secured to type-wheel carrier 4, can be moved.
  • spring 22 In the initial position spring 22 always presses the axle against the left hand side of slot 51.
  • the type-wheel carrier will be able to swing slightly about axle 13, because axle 14 slides to the right in slot 51.
  • the tension of spring 22 regulates the power of the pressure of the type-wheel against the paper.
  • roller 53 which is mounted on type-wheel carrier 4 by means of axle 54, will push the rack 56 of stopping lever 28 away from toothed wheel 8, and it will push it so far that it is stopped in the initial position (see Fig. 1) because projecting part 55 of stopping lever 28 is engaged with hook 29.
  • Cam 38 now moves back roller 39. This moves arm 35 (which was retained in the initial position by spring 41) and causes it to turn about axis 37, which brings all typewheel carriers 4 back to their initial position. In the two positions of rest, each type-wheel carrier is retained by spring 22.
  • Type-wheel carriers 4 are not brought back to their initial position before type-wheel 2 will have turned so far that the part of the type-wheel facing the paper bears no types, and no'type can therefore now touch the paper.
  • stopping lever 28- is released by magnet 33 becoming magnetized through a current which is established through a hole in the card. There is no objection to the release of stopping lever 28 being effected through mechanical means as the hole in the card ispassing. The printing device would be the same otherwise.
  • rack 56 provides for an efiicient stop for the teeth of wheel 8 and prevents any failure in the working.
  • a printing device especially adapted to be used in connection with tabulating machines for perforated cards which comprises in combination. a fixed frame, a plurality of supporting members jointed to said frame so that they can be given a translatory motion with respect thereto, a set of toothed wheels in mesh with one another carried by each of said supporting members, a paper roll, a typewheel journalled on each of said supporting members opposite said paper roll and in mesh with one of said toothed wheels, a plurality of types carried by said typewheel on the periphery thereof, a driving toothed wheel meshing with one of the wheels of said set and journalled about a stationary axis with respect to said frame, a movable member provided with a plurality of teeth located opposite one of the first mentioned wheels, and means for bringing the last mentioned member in contact with the last mentioned wheel.
  • a printing device especially adapted to be used in connection with tabulating machines for perforated cards which comprises in combination, a fixed frame, a plurality of supporting members, a plurality of links jointed both to said frame and to said supporting members so that said members can be given a translatory motion with respect thereto, a set of toothed wheels in mesh with one another journalied in each of said supporting members, a paper roll, a typewheel journalled on each of said supporting members opposite said paper roll and in mesh with one of said toothed wheels, a plurality of types carried by said typewheel on the periphery thereof, a driving toothed wheel meshing with one of the wheels of said set and journalled about a stationary axis with respect to said frame, a pivoting lever provided with a plurality of teeth located opposite one of the wheels carried by each supporting member, means for keeping said lever in the inoperative position so that the last mentioned teeth are kept away from the wheel opposite which they are located, elastic means for actuating said lever so as to bring the last mentioned teeth into mesh with the last
