.This invention relates to circuit making and breaking devices for electromagnetically.operated reciprocating mechanismsand ithas for its primaryobject to provide acoupling between the members controlling the 'energization of the electromagnetic coils and the reciprocating members, which permits intermittent operation and idle motion of the positively moved coupling members within the members controlling the energization, which coupling uses means fOrpI'o- -ducing said intermittent coupling which are easily adaptable to different types of mechanisms and to :different strokes of the reciprocating members and which are'easily adjustable in order to obtain greatest precision.
A further object of the invention consists in providing a circuit making and breaking device of the character above indicated of great simplicity, operatingwith a .minimum of moving or movement transmitting parts, which device is positive andautomatic in its operation and at the same time is self-contained-and reliable, and may be finely adjusted for action at predetermined phases of operation.
A still further objectof the invention consists in providing a circuitbreaker construction which will produce a pressure at the contacts which is suificient for perfect contact and safe operation.
Further objects will become apparent in the .course of the following detailed specification.
The invention .is illustrated'inthe accompanying drawing showing one embodiment thereof.
.It is, however, to be understood that this embodimentis merely one example intended to illustrate a practical application. The invention is described and illustrated in such'a manner that further embodiments-may be constructed without difficulty by persons skilled in this art and these further embodiments which have been foreshadowed by the following specification as far as included in the annexed claims, are therefore part of the invention and do not constitutedepartures therefrom.

It will be understood that theinventioncoming arrangement and its combination with the electromagneticall-y operated driving mechanism thereby. For the sake of illustrating one pracfor .fuel pumps was arbitrarily selected. This driven device is not=of influenceon the driving electromagnetic .device with its circuit breaker mechanism.
Thearrangement shown in Figure 1 comprises a casing 5 fixed on the. diaphragm pump.6, which comprises, as .usual, a diaphragm I, held one.
I 0, a delivery chamber I I, a delivery or outlet opening 2|, a fluid admission chamber [2, asuction chamber 13, a suction valve M, andan admission opening 23, all these parts arranged and The plunger 8 is screw-threaded and carries nuts l5 clamping an arm I6. 'Its end is screwed into the core is of a solenoid or electromagnet 29.
finding its base in a plug or socket 24.
The-electromagnet comprises a coil "25 fixedly mounted within the casing, whose circuit is to produce a reciprocating This control of the circuit of the solenoid or electromagnet 2i! is'performed by means of the circuitmaking and'breaking arrangement designated ingeneral by the reference numeral :30. It consists of the arm :56 carried "byplunger 8 through opening zs'intothe interior of asleevejecting foot members 34 and screws 1 and 4).
On its upper-endithegui'de tube or slide :carrier 3215 provided with a'laterally 'projectingbra-cket 38 which, by means of'insulating'washers .33'car- -ries a contact spring 49, having a pre-selected At the end of thesprin'g T36 (Figures a'contact A! is'mounted.
'In the 'hollow'interior :of the guide tube .32 a slide 44 is movable which :consists, as shown in Figures 1 and 5, of a metal strip with a U-shaped bent portion 42 which fills the entire section of the guide tube 32, so that the straight portion glides on one side thereof while the bent portion glides on the opposite side.
It will be seen from Figure 1 that the bent or retracted portion 42 causes the formation of a gap or cavity 48 in the slide into which the arm l6 enters.
Through the side walls of the bent portion, setscrews 49, 50 are projecting, which cooperate with the end of arm 16. The width of thegap and the distance between the set-screws which is finely adjustable determine the extent to which the arm may travel without moving the slide and thereby determine the length of the piston stroke.
The end of the slide 32 is bent (at 46) and is provided with an insulated contact 41 which cooperates with contact 4| on spring 40.
To hold the slide 44 in its correct position within the guide tube 32 during its movement a spring 52 is provided which presses against the straight portion of the slide. This spring not only holds the slide in its correct position in which the straight parts are lying flat on the guide but by virtue of the friction produced by the pressure also holds the slide in whatever position into which it may have been shifted. In order to avoid displacement of the spring small tongues 53 may be punched out in the guide tube near the upper end thereof and may be bent inwardly, so as to form a support for the spring.
The operation of the device will be clear from the foregoing detailed description. When the plunger 8 is moved downwardly the arm I6 reaches the set-screw 49 and moves the contact 41 towards contact 4| on sprin 40. It will be noted that spring 40 is somewhat depressed during the last phase of the downward movement so that it presses the contacts firmly against each other, preventing imperfect contact between the same.
When the contacts 4| and 41 close the circuit of the solenoid magnet 20, the latter attracts core I 8. thus starting an upward movement. The cirduring the first phase of such movement as arm l6 moves within gap 48 without moving the slide. Finally, near the end of the stroke arm l6 strikes against screw 50 and entrains slide 44. The slide,
-in moving upwardly, moves contact 41 away from contact 4i and spring 48 whereby the circuit of the solenoid is interrupted. Spring 22 moves the core downwardly and the cycle starts again.
When the circuit breaker is at rest, the spring 22 holds the arm IS in its lowermost position and, therefore, holds contacts 41 firmly in engagement, thus holding the device in readiness for immediate further operation.
It will be seen from the above that the circuit breaking device according to the invention operates safely with a. minimum of moving parts, and permits adjustment of the stroke individually as well as adjustment for different types of solenoid magnets. It is especially adapted for mass production.
It is also to be understood that the foregoing description, while giving specific rules of construction, intends to outline the principles involved so that it will be manifest to experts that the parts, members and devices specifically described may undergo many constructive changes without, however, leaving the outlined principle on which the invention is based.
cuit of the magnet is, however, not interrupted I claim:
