Abstract
The effective length of a control arm having manually alterable stops repositionable along is rendered automatically changeable by means of a solenoid movable strip arranged to be either pressed against the control arm or removed from contact with the control arm by operation of the automatically operated solenoid which may usually be operated by a change in the surrounding ambient temperature.
Claims12
An automatic adjustment for coal stokers using a reciprocating feed movement of a plate at the bottom of a stoker comprising the use of:
- a low power solenoid arrangement mechanism to move a light solenoid arm into the path of a normally manually adjustable setting means to cause a reciprocating movement of a feeding mechanism to have an increased scope.
An auxiliary control means for altering the range of control of a reciprocating control arm which oscillates between manually adjustable stops comprising:
- (a) a reciprocable control arm with at least one manually adjustable stop;
- (b) a solenoid provided with a condition responsive detector;
- and
- (c) a predetermined width spacer means in operative contact with the solenoid;
- (d) whereby when the solenoid is operated the spacer is brought against the reciprocating control arm adjacent to the at least one adjustable stop in order to effectively automatically change the length of oscillation between manual set points on the reciprocating arm.
A device for automatically varying the stroke length of a slideable plate type coal stoker assembly having a radially projecting shoulder plate member comprising:
- a spacer arm having a blade section and an end section spaced from said blade section, said spacer arm pivotably connectable to said coal stoker assembly and being pivotable between a first position in which the blade section is interposed between stop connected to a rod passing transversely in a reciprocating motion through an aperture in a plate member forming part of the stoker assembly thereby increasing the stroke length of the slideable plate, and a second position in which the blade section is not positioned between the stop and plate member;
- and
- means for pivoting the spacer arm between said first and second positions.
