Definitions
- the invention comprises two electromagnets in contact with one of two stops a mounted on or solenoids, energized alternately by a spring but insulated from the casing.
- the stops 0. are carried on a plate A of 15
- the invention further comprises the provision insulating material adjustably mounted on the of a plurality of cam discs given a rotary movecasing by a spindle a screwing therethrough to ment by the switch to control external electric propel a. bracket a affixed to the plate A.
- Fig. 1 is a front elevation showing the 0011- of the contact a.
- the casing E travels over a roller 11 carried by Fig. 2 is a similar elevation showing the 0011- the lever D, tact maker in the other extreme position.
- the rate at which the spring (1 causes the 25 Fig. 3 is a side elevation.
- lever A to travel between the two stops a is 4 is a Section 011 ine ig. 1.
- a connecting 5 is a p of the m g t rod 0 pivoted to the lever A and to a toothed Fig. 6 is a detail view of the contact maker.
- quadrant The quadrant gears th a pin- Fig. 7 is a detail view of the lever D and star ion 0 on a spindle 0 also carrying a further 30 wheel.
- pinion c which engages a pinion c on a spindle Fig.
- FIG. 8 is a detail view of the cam discs and carrying a wheel 0' engaged by an escapement contacts for exterior ir i c pivoted on the casing on a spindle 0
- the switch is opera-ted y a Contact maker 63 gearing retards the rate of movement of the controlled by two solenoids B through gearing t t d th o ition of the stops a de- 35 C W c provides a time lag the movement termines the distance which the contact a o the Contact maker has to travel between them.
- the solenoids B are arran ed to be energized Current is fed to the solenoids by a lead from alternately and are constructed with common n i s lated terminal 2 on the casing, the rearmatu e b a p t0 be drawn first in one turn lead 3 from one solenoid being connected direction and then in reverse by first one and t one top and the return lead 4 from the then the other of the solenoids.
- the con- DOTtiOn 0f the armature b is recessed and D tact a completes the circuit to the casing into vided with a p n 1) Which engages a Slot (1 in which is screwed a return terminal 5.
- Two discs F F having a series of cam faces are also mounted on the spindle a each disc being engaged by one or more rollers g (two are shown in the drawings).
- Each roller g is mounted on a lever g and held in contact with the cam surface by a spring g
- a contact arm G is mountedon each lever g and as the cam disc rotates is intermittently brought into and out of contact with an insulated terminal 6 on the casing E thus intermittently making and breaking an electric circuit completed through the casing by the return terminal 5.
- intermittent electric switch comprising a casing, a spring operated switch arm, two
- solenoids energized alternately by the switch arm, a common armature for the solenoids, 2. depending .lever “pivoted on the casing, a pin onuthe armatureengaged by the lever, a pin on the leverv to transmit the movement to the contact maker, gearing to retard theoperation of the contact maker, further pins on the depending lever, and a star wheel intermittently rotated in one direction by the pins.
- An intermittent automatic switch comprising a casing, a spring operated switch arm, two solenoids energized'alternately by the switch arm, a common armature for the solenoids, a lever pivoted to the casing and oscillated by the armature, a pin on the lever to engage a slot in the switch arm, a lever pivoted to the switch arm, a quadrant pivoted to the casing and partially rotated by the lever and escapement gearing operated by the quadrant to retard the rate of movement of the lever and switch arm.
- An'intermittent automatic switch comprising a casing, a spring operated switch arm, two
- solenoids energized alternately by the switch arnxa common-armature for the solenoids, a lever pivoted to the casing and oscillated by the armature, a pin on the lever to engage a slot'in the lower portion of the switch arm, a lever pivoted to the upper portion of the switch arm, a triangular contact member on the upper pore tion of the switch arm adjustable contacts on the casing engaged by the triangular contact member, a quadrant pivoted to the casing and partially rotated by the lever and escapement gearing operated by the quadrant to retard'the rate of movement of the lever and switch arm.
