Definitions

  • the present invention relates to a telephone index of the kind that is preferably intended to form a base plate for a table telephone and in which the numbers of various subscribers may be recorded on index cards which can be made visible by a simple manipulation when the number of a certain subscriber is to be locked up.
  • a telephone index of this general kind is the subject matter of the Swedish Patent 173,234.
  • This previously known telephone index consists of a flat case in which a tray is movably guided.
  • the tray carries a pile of cards from which any desired number of index cards may be pulled out.
  • the bottom side of the tray is provided with a shaft on which a number of double-armed levers are pivotally journalled in a row.
  • the rear ends of the levers are designed with upwardly projecting heads in each of which a pulley is rotatably journalled and projects slightly above the top of the head.
  • the tray is provided with an opening through which the heads with their pulleys, which are normally in their inoperative position located beneath the top of the tray, may be moved up by pivoting the levers.
  • the index cards are provided with notches the width of which increases from one card to the next in such a way that on actuation of a lever the head thereof is moved up through the notches in a predetermined number of index cards and brings these cards along when the tray is pulled out.
  • the remaining cards are pressed by the pulley against the underside of the upper wall of the case and are'kept against it by friction While the tray is being pulled out.
  • the telephone index described above has become quite popular and functions rather satisfactorily, but nonetheless it cannot be denied that there are some inconveniences and defects connected with it.
  • the index consists of a rather great number of separate parts so that the assembly becomes bothersome and consequently rather expensive.
  • the individual index cards are, so to speak, pushed out by action on their rear edges.
  • the object of the invention is to provide a telephone index in which the above defects or inconveniences are eliminated.
  • the telephone index according to the invention is substantially characterized in that, at their fore edges located next to the open end of the case, the index cards are provided with aligned holes for engagement with said second lever ends in a number decreasing from top to bottom from one card to the other in the pile in such a way that on actuation of a lever the other end thereof engages holes in those cards which have a position corresponding to the position of the lever in the row, while the remaining cards are raised at least slightly, and in that near its open end the case has rearwardly directed, inner hooks or stops which on outward movement of the tray catch the cards thus raised and prevent them from being pulled out.
  • the telephone index consists of a flat case 10 in which a tray 11 is movably guided.
  • the tray 11 carries a pile of cards 12 from which any desired number of cards may be pulled out.
  • Doublearrned levers are provided for the selection of the index cards. These levers are pivotally journalled in a row on a shaft 13, and in the drawing only one of them is illustrated by the lever 14. A detailed description of the levers 14 and the manner in which a desired number of index cards is selected will be given below.
  • the fiat case which is preferably made of plastic, has side walls 15, 16, a rear wall 17 and a top wall 18. These walls are preferably integral and the side walls are extended to form two shanks 19, 20 projecting in front of the top Wall. Guides for the tray 11 extend along the inner sides of the walls 15, 16 but as such guides may be designed in many different ways they have not been shown in the drawing. In front the fiat case 10 is entirely open, and rearwardly directed hooks or stops 21, 22 are provided in the opening near the inner sides of the walls 15, 16 for a purpose to be described below.
  • a box-shaped mechanism housing 23 is secured to the foreedge of the tray 11 "and contains the above-mentioned shaft 13 with the pivotal levers 14.
  • the top side of the mechanism housing 23 has a longitudinal slot or recess 24 for the purpose of improving the grip of a finger tip when the tray 11 with the pile of cards 12 is to be pulled out.
  • the fore ends of the double-armed levers 14 pivotally journalled on the shaft 13 are designed as keys 14A projecting through suitable shaped holes in the top of the mechanism housing 23 within the area of the slot or recess 24.
  • the rear ends of the levers are shaped as arcuate hooks 14B extending through holes in the tray 11.
  • hooks 14B either engage the holes 25 in the cards or raise the cards located above.
  • the rear side of the mechanism housing 23 is provided with an abutment 26, the rear surface of which is vertical and on the hori- Zontal top surface of which either advertising text or telephone numbers of predetermined subscribers, such as socalled emergency numbers, may be written.
  • a leaf spring 27 is disposed on the inner side of the rear wall 17 of the flat case 10 and urges the index cards forwards in the case.
  • pivotally journalled double-armed levers 14 are biased towards the position of rest shown for the majority of them in any suitable manner, such as by separate springs or by dimensioning the weights of the lever arms such in relation to each other that the levers of their own accord strive to return to the position of rest.
  • any suitable manner such as by separate springs or by dimensioning the weights of the lever arms such in relation to each other that the levers of their own accord strive to return to the position of rest.
  • the second key 14A from the left in the row of keys is depressed. Thereby the arcuate hook portion 14B moves through the corresponding holes 25 in all the index cards having a hole in this position. However, the topmost index card 12A has no hole in this position and therefore it will be raised slightly by the end of the hook 14B.
  • the tray 11 is pulled out by gripping with the tip of a finger in the recess 24, thereby pulling out all the index cards caught by the hook .14B, whereas the topmost card 12A has been caught by kept pressed against the hooks 21, 22 by the spring 27, 'will of course during the inward movement of the tray be lifted ofi these hooks by the abutment 26 and be arranged accurately together with the other cards in the pile in readiness for the next occasion.
  • index described is useful not only as a so-called telephone index but it is also useful in any similar connection, such as for stock indexes, membership registers etc.
  • topmost card entirely without holes it is of course possible to gain one key function, as said topmost card will always be pulled out together with the tray if no key is depressed.
  • This card may contain information about code numbers etc., for instance.
  • the index cards may be printed on both sides, and be arranged to be turned upside down for utilization of both sides thereof.
  • the index being provided with a number of aligned, pivotally journalled double-armed levers having one end actuatable manually for the purpose of selecting the desired number of index cards and having the other end adapted to engage the index cards on actuating of the lever in question, characterized in that at their fore edges located next to the open end of the case, the index cards are provided with aligned holes for engagement with said second leverends in a number decreasing from top to bottom from one card to the other in the pile in such a way that on actuation of a lever the other end thereof engages holes in those cards which have a position corresponding to the position of the lever in the row, while the remaining cards are raised at least slightly, and in that near its open end the case has rearwardly directed inner hooks or stops which on outward movement of the tray catch the cards thus raised and prevent them from being pulled out.
  • a telephone index according to claim 1 in which a tray is provided with a mechanism housing at its foremost edge, characterized in that a shaft for pivotally journalling the levers is accommodated in the mechanism housing, and in that the fore ends of the levers, which are 1 designed as keys project through the top wall of the mechanism housing within a portion thereof provided with a grip recess, the rear ends of the levers being designed as arcuate hooks for engaging the holes of the index cards and for raising theindex cards, respectively.
  • a telephone index according to claim 1 characterized in that a resilient member, such as a leaf spring, for instance, is disposed at the rear wall of the case to urge said raised cards into the hook members which have caught them, when the tray is being pulled out, a vertical abutment surface being provided at the rear side of the mechanism housing to move the raised cards out of engagement with the hooks at the return movement of the tray.
  • a resilient member such as a leaf spring, for instance
  • a telephone index according to claim 1 characterized by an abutment provided at the rear side of the mechanism housing and having a rearwardly facing vertical abutment surface for arranging the index cards in the pile at the inward movement of the tray and preferably a horizontal top surface for accommodation of an advertising text, emergency numbers or the like.
  • a telephone index according to claim 2 character,- ized in that a resilient member, such as a leaf spring, for instance, is disposed at the rear wall of the case to urge said raised cards into the hook. members which have caught them, when the tray is being pulled out, a vertical abutment surface being provided at the rear side of the mechanism housing to move the raised cards out of engagement with the hooks at the return movement of the tray.
  • a resilient member such as a leaf spring, for instance
