Definitions

  • This invention relates to timing mechanisms for machines, particularly for washing or dry cleaning machines, of the type in which a series of operations is carried out in a predetermined order according to the setting of the machine.
  • a supplementary control hereafter referred to as the position-control
  • the timing mechanism proper hereafter referred to as the time-control
  • the mechanism, object of this invention is particularly adapted to the control of washing or dry cleaning and like machinery, the successful working of which depends on the successive operation of supply valves and drain valves, so as to accurately control the admission and draining of the various liquids (cold water, hot water; detergents and other washing reagents) in predetermined sequence and quantity, according to the laundering or other operation-sequence formula, in accordance with which it is desired that the machine should operate.
  • the mechanism can be used. for controlling any predetermined sequence of operations of similar kind to that just described, namely, having for its object the displacement of any liquid or liquids, for any purpose to which the method of position-control herein described may be applied.
  • the timing mechanism, object of the invention is hereafter described in connection with the operation of a washing or dry-cleaning machine, its use is therefore not limited to the operation of such a machine, as will be made clear hereafter.
  • FIG. 1 is a side elevation of the present invention
  • Fig. 2 is a vertical section taken substantially on the line 22 of Fig. 1.
  • A is the time-control device proper
  • B is the position-control.
  • Reference character I is the record, here a perforated band, wound on the drum 2 pivoted at a and gradually fed on the drum 3, pivoted at b, by the action of the ratchet 4 and ratchet teeth 5 actuated by the linkwork 6, I, 8 pivoted at b and c.
  • the element 8 carries a roller 9 which is normally depressed by a cam
  • the levers 5 6, and 8 are returned to their normal position by gravity or by any other suitable means (not shown).
  • the cam Ill depresses the roller l2, thereby actuating levers 53, i l,
  • the feeler ll engages an unperforated portion of the record it merely slides in sleeve l5 l6 against the pressure of the spring l8, which is adjustable by means of the screw
  • On being engaged by the rocking lever ll, the pawl 2
  • first depresses the roller 28 of the catch 29 pivoted at f, against the action of a spring 29' by means of an incline 2
  • the catch 29 is capable of being depressed by a feeler
  • the feeler lib penetrates in the aperture of the drum and reaches a projection 32 carried by the catch 23, depressing the latter and causing it to release the pawl 2
  • the drum III is mounted on a sheave 33 actuated by a float by means of the cord 34 After the termination of the sequence of operation, the record-is re-wound on the drum 2 by means of the handle 2a.
  • the rocking of the arm ll feeds the record forward until the first perforation passes under the feeler I1, when the lever 23 is pushed forward, as described, and the tap is opened by the rod or wire 25, and maintained in the open position owing to the fact that the lever 23 is locked in its forward position, so that water is entering the container the level of liquid in which it is required to control.
  • the float rises and the drum 33 revolves, and with it the drum 30.
  • the feeler lib inoperatively strikes the surface of the drum 30, but as soon as the aperture 3
  • the means described herein to actuate the portion of the mechanism concerned with the position-control is by no means a characteristic of the timing mechanism according to this invention, and that it may be replaced by any other means depending on the movement or position of any member of the actuated mechanism, so that the timing mechanism, object of this invention, can be applied generally to the control of a predetermined sequence of operations of any description capable of supplementary position-control by means actuated by a material element variable in position, without departing from the spirit of the invention as described above. It is, for example, particularly suitable for automatically stopping and restarting machines, for operating a dumping apparatus and like applications.
  • a timing mechanism for controlling a series of predetermined operations to be performed by a machine comprising, a perforated member, a drive shaft, a rocking lever actuated by said shaft, an operating lever, means actuated by said rocking lever to advance said perforated member, a
  • A-device according to claim 1 including means adapted to return said operating lever to its original position.
