Definitions

  • the present invention aims to avoid these difficulties in the assembling.
  • the mobile organ according to the present invention is characterized in that the shaft is removable and presents, at one of its ends, a securing element adapted to be connected with the toothed member, in a position coaxial with the latter, by simple axial displacement of the shaft in a direction towards said member.
  • the illustrated movement comprises a base plate 1 and an upper bridge 2, which form the two opposite elements of the movement frame.
  • bridge 2 extends the dial 3 provided with a central circular opening 4.
  • the bridge 2 has in its upper face an annular recess 5 situated in a line with the opening 4 which traverses the bridge 2 on a portion of the periphery thereof and from the center of which projects a cylindrical sleeve 6 secured to the bridge 2 and extending through the opening 4.
  • On this sleeve pivots a cannon-pinion 7, the toothing of which meshes with a barrel 8 arranged between the frame elements 1 and 2.
  • An hours-wheel is engaged on the cannon-pinion 7.
  • the toothing of this hours-wheel extends between the bridge 2 and the dial 3.
  • a minutes-hand and an hours-hand 11 are secured to the upper end of the cannon-pinion 7 and of the hours-wheel 9, respectively.
  • the barrel 8 is provided with a toothed crown 12 meshing with the pinion of an excentered center wheel (not shown).
  • This pinion drives the pinion of a third or petitetown wheel 13, which in turn drives the seconds-wheel fromed 'by a toothed member 14 and a shaft 20.
  • the member 14 is formed of one piece of injected plastic material. It is axially traversed by a passage 15 the lower end of which presents a conical entry opening into a hub 16 formed in the center of the lower face of wheel 14.
  • the upper end of passage 15 also is shaped to produce a cylindrical zone 19 which opens into the plane upper face of the pinion of member 14.
  • the shaft 20 has at its lower end of a cylindrical step adapted to the dimensions of the opening 19, this step being limited by a collar 21.
  • the shaft 20 presents two collars 22 and 23 situated within a cylindrical portion of a passage 24 traversing the sleeve 6 in axial direction. As seen in the drawing the passage 24 is slightly widened out at its upper portion.
  • a secondshand 25 is secured to the upper end of shaft 20.
  • the assembling of the described movement is effected in the following manner:
  • the ditferenent Wheels of the going train are successively placed onto the base plate 1, the barrel 8 resting on a ratchet wheel 27, which itself is placed on the plate 1.
  • the mobile 14 is positioned without its shaft 20. It is maintained in a stable position coaxial with respect to the movement owing to the peg 18 and to the hub 16.
  • the mobile 14 is axially engaged between these two frame elements, whereupon the upper base 2 is placed and secured with its periphery to the plate 1.
  • the cannon-pinion 7 and the hours-wheel 9 may be engaged on the central sleeve 6 whereafter the dial 3 and the minutes and hours hands may be mounted. All that has to be done then is to introduce shaft 20 through passage 24 and to exert an axial pressure to frictionally engage its step into the passage 19 whereby the collar 21 bears against the upper face of the pinion of mobile 14.
  • Both elements of the fourth-Wheel are thus connected with each other.
  • the placing of the seconds-hand 25 may be effected afterwards or before the placing of the shaft 20. While the mobile described hereinbefore pivots on a stationary peg 18 it could of course in another embodiment present a pivot connected with the mobile 14 and projecting downwardly.
  • the plate 1 would then be provided with a conventional bearing adapted to receive this pivot.
  • fourthor seconds-wheel described hereinabove could also in another embodiment be dimensioned so as to form a fourth wheel placed in a position excentered with respect to the movement.
  • the described mobile organ comprises an independent shaft which may be positioned after the assembling of the movement, such assembling is highly facilitated since the seconds-wheel may be placed in a stable position coaxially with respect to its bearings and since it is not necessary any more to take particular care to this mobile during the positioning of the upper frame elements.
  • a watch movement comprising a first frame member, a toothed member rotatably mounted adjacent said frame member, one of said members containing a bore receiving a pivot stem carried by the other, and one of said members providing an annular abutment engaging the other and coaxial with said stem, a second frame member spaced from said toothed member and disposed on the opposite side thereof relative to said first frame member, said second frame member having a wall defining an elongated passage aligned with said stern and open at both ends, and a shaft insertable and removable through said passage for engagement and disengagement respectively with said toothed member, said shaft extending beyond both sides of said second frame member and having a surface in bearing engagement with said wall.
