Definitions

  • MALCOLM L COSSIT'I. OF ALAMEDA, CALIFORNIA. ASSIGNOE TO MANIFOLD IMPRESSIONS CORPORATION. OF CARSON CITY. NEVADA, A OORYORATION OF NEVADA Specification of Letters Patent.
  • My invention relates to manifolding attachments to type-impression machines comprising typewriters, calculating machines and the like, and its object is to provide a simple, cheap and eli'ective device adapted both for single and plural copies upon loose sheets of paper, without the use of ordinary carbon sheets, said attachment employing one or more manifolding members of approximately the length of the platen, and adapted to be either independently or collectively carried from an inoperative position into functional position between adjacent Sheets of loose paper, in the line or re gion of type impact.
  • Another object of my invention is to lock said manifolding members independently or collectively both in inoperative and in functional position. by means requiring such deliberate operation, as will insure safety both in and out of use.
  • Another object is to control the movement of the manifolding. members in their path to the line or region of type impact, so that they may reach their functional position and depart therefrom without interference with fixed parts of the machine.
  • Another object is to provide for the movement of the manifolding member with each line spacing movement of the'platen, in order to change its position with each line with respect to the line of type impact, thereby lengthening the life of said member.
  • Xnother object is to provide simple and efl'ective means for attaching and detaching the manifolding members to and from the r carrying members.
  • Fig. l is a top plan view of a portion of a tvpewriting machinm showing my attachment applied thereto, the manifolding mem' bers being in normal position of rest, out of use.
  • Fig. 2 is an end view from the left of my mamfolding attachment, the position being one of locked rest, out of use.
  • Fig. 3 is a similar view, showing the initial unlocking of the manifolding members.
  • Fig. 4 is a similar view showing the several members progressively moved forward about their respective individual axes.
  • Fig. 5 is a similar view showing all said members fully moved about their dual axes to reach a locked functional position in the line of type-impact
  • Fig. 6 is an end view from the right of my attachment showing the manifolding members at locked rest, out of use.
  • Fig. 7 is a similar view showing said members unlocked and'progressively started towards their functional position.
  • Fig. 8 is a detail plan view, broken and partly in section, of one end of the machine platen and of my attachment.
  • Fig. 9 is a detail showing the attachment of the manifolding member to the carrying arm.
  • Fig. 10 is asection of the same on the line 10-10 of Fig. 9.
  • Brackets one at each end, Fig. 1. These brackets are formed with feet 2 adapted by means of screws 3 to be secured to the machine.
  • Figs. 6, T and 8 In the top of the bracket at the right, Figs. 6, T and 8, is journaled a short shaft 4, upon the outer end of which, as shown in Figs. 1 and 8. is fitted a hand wheel 6,to turn the shaft on its axis.
  • the inner end of the shaft l carries a crank 5.
  • sleeve is in dependently turnable on its axis.
  • the in nerinost sleeve 5 has liscd at each end an which a spring arm 9' and the has an arm 9".
  • a small finger-grip handle 10 is secured to the arm 9 at the right, another handle 10 to the arm 9' and another handle 10" to the arm 9", as shown in Fig. 1, the last named two handles fittin in open grooves 11, Figs. 6 and 7, in the middle and innermost arms respectively, so that the three arms lie nested snugly together when not in use.
  • a manifolding member say, for example, a section of manifolding ribbon 12, a. similar section of manifolding ribbon 12' being carried by and between the arms 9' and a similar ribbon section 12" bein carried by and between the arms 9". See Ti 1.
  • the former movement namely that with the shafts 4 and 4' for an axis is effected by operatin the hand wheel 6; and in order to limit an define this movement at eachend thereof, there is secured to the short shaft 4 a two-notched stop 13, Figs. 6 and 7, with dctent l4 coacts.
  • the upper notch of the stop limits the upward and backward movement of the shaft 4. as in Fig. 7, and the lower notch limits the forward and downward movement, as in Fig. 6.
  • the second movement of the ribbon sections. namel that having the rod 7 for an axis is contro led by stop fingers 15, 15' and 15". Figs.
  • a pinion 20 Journaled on a short stud 19 carried by and projecting inwardly from the right hand bracket 1 is a pinion 20, Figs. 6 and T. which carries on one side a cam 21.
  • This cam operates within a yoke 22 pivotully carried upon and depending from the short shaft 4.
  • the movement of the pinion is adapted, through the cam 21, yoke 22.
  • the spring detent 14 is carried by the yoke 22, as seen in Figs. 6 and 7.
  • a metallic clip 23 which at one side has a fold 24 which is pressed or crimped down u n the folded end of the ribbon section, an at the other side is provided with a bent tongue 25 which lies within and engages a notch 26 in the outer side of the arm.
  • a metallic clip 23 which at one side has a fold 24 which is pressed or crimped down u n the folded end of the ribbon section, an at the other side is provided with a bent tongue 25 which lies within and engages a notch 26 in the outer side of the arm.
  • the ribbon section is to be held under proper tension by any suitable means; in practice, a feasible way is by a slight yieldmg or resiliency of the arms so that by pressing them towards each other, the attachment of the clips may be made, and upon the release of pressure, the arms, springing back, will hold the ribbon taut.
  • FIG. 1 I have illustrated such portion of a typewriter as will sulfice for a proper understanding.
  • 27 is the frame of the machine; 28 are some of the keys: 29 is the platen with shaft 30 and hand wheel 31 all mounted on the usual platen carriage; 32 is the spacing ratchet of the platen: 33 is the spacing; and carriage-returning lever; 3- is the pawl operated by said lever and engaging the spacing ratchet; 35 is the regular typing ribbon of the machine; 36 are the ribbon drums: 37 is the index pointer; and 38 is the paper guide-apron.
  • the connecting members will be of such nature as to effect a proper union.
  • manifolding ribbons are independent single length sections of approximately the length of the platen and lie parallel therewith. and their dual axes of movement are parallel with the axis of the platen. The normal rest position of the parts, by
  • the ribbon sections are all free to be brought into play, but as we are assuming that only one 18 required, the operator takes hold of the handle 10 of the arms 9" of the front ribbon section 12".
  • This ribbon section is then turned forwardly and downwardly on its own axis on rod 7, describing an air which carries it down close to the front of the platen, and in a plane well inside and clear of the index pointer 37 of the machine, as seen in Figs. 4 and 7. which thus pre- 'scnts no interference; but its position just described is still above its functional position.
  • the operator in thus bringing the ribbon section to its first position with reference to the platen. separates the advance edges of the two sheets of paper in the machine, so that the ribbon section 12" passes down between them.
  • ribbons refers to and includes'strips having a general'ribbon shape. They may be of any suitable material, and their preparation may vary. as. for example, they may have an im pression or ink surface on one side only, the other side being a non-impression one; or if it be desired to make one ribbon produce two copies one of which is a tissue paper sheet to be read by transmitted light, the ribbon may have both sides inked in the for oing description of the operation. it wil be noted that the swing of the mam-folding member, in describing its initial downward movement.
