MANSUR, F EABDIN, IfllISSOURI STARTING SWITCH FOR AUTOMOBILE ENGINES Application filed February 4, 192?. Serial No. 165,968.
The present invention is directed to improvements in starting switches for automobile engines.
The primary object of the invention is to provide a. device of this character so constructed that when the ignition switch is closed the starting motor will be placed in operation, thereby starting the engine without the necessity of actuatlng a starting button, or the like,'as is now customary. Another object of the invention is to provide a device of this character so constructed that the vacuum dreated in the intake manifold of the engine will automatically control the operation of thestarting motor, whether initially'starting' the automobile or should the same become stalled in traflic. In the accompanying drawings Figure 1 is a side elevation of the device showing the same associated with the intake and carbureter of a motor vehicle.
Figure 2 is a view, partly in section, showing the switch controlled by the construction shown inFigure 1. I
25 Figure 3 1s a view of the wiring circuit.
Figure 4 is a sectional view on line 4--4 of Figure 2. r
Referring to the drawings, 1 designates a carbureter and 2 the throttle valve operating lever, the mixture from the carbureter, as customary, enteringthe intakemanifold 3.
Fixed to the'engme, not shown, or on anyother part of a motor vehicle is a frame 4, having fixed thereto a cylinder 5, said cylinder being in communication with the manifold 3 through the ipe 6. Slidable in the cylinder is a piston 7 the rod 8 fixed thereto being extended through the head 9 of said cylinder.
A relatively rigid contact plate 10 is suported by the frame 4 and may be ad'usted, 1 f desired, through the medium of t e nut 11 and threaded shaft 12, the inherent resiliency of said plate operating to, this end. This plate. is in circuit with the binding post 13 through the conductor 14, and also supported by the frame 4 is a resilient contact arm 15 in circuit with .the bindingpost 16 through the conductor 17 A post 18 is sup- 50 ported by the frame 4 and pivotally supported,
thereby is a bell crank lever 19," the arm 20 of which. is pivotally connected to the piston rod 8 by a link 21. The arm 22 of the lever has the rear terminal of the coil sprin 23 connected thereto, the forward end of w ich is secured'to the frame 4 by an adjustable screw 24. The spring normally holds the contact arm 15 in contacting relation with the plate 10. To limit the rocking movement of the lever 19 in one direction a screw 25 is carried by the frame and obviously arrests the movement of the arm 22, as indicated in dotted lines in Figure 1. The frame 4 is ref-- erably formed with end flanges 26 an top and bottom flanges 27 and 28, the screw 24 being engaged in one end flange while the post 18 is supported by the lower flange, as 1s the screw 25, which is provided with a head29 to facilitate the adjustment thereof.
The starting motor switch is designated generally by the numeral 30 and comprises a metallic plate 31 adapted to be attached in any suitable manner upon the motor vehicle. The plate has fixed thereto electro- magnets 32 and 33, the coil 34 of the former being grounded through the wire 35, while the coil 36 of the latter is in circuit with the post 16 through the conductor 37 The armature 38 has contacts 39 upon its ends for contact with the contact heads 40 and 41 of the respectivesmagnets: 4 Supported upon the plate 31 is a'housing 42, contact plates 43 and 44 being carried by said plate and located in the housing. The contact plate 44 is in circuit with the starting motor 45 through the conductor 46. The contact plate 43 has leading therefrom a conductor 47 which is in circu1t with the battery '48 through the wire 49, the battery being,
grounded through the wire 50. The circuit is completed through the arm 15 and plate 10 through the conductor 51 when the ignition switch 52 is closed.
Upon the housing 42-is mounted a casing Y53, and telescopically engaged therewith is a casing 54, said casings bein rectangular in cross section, to prevent rotatlon of the arms.- ture 38 to .which the casing 54 is fixed. Having'its upper end fixed centrally to the armature 38 is a bolt 55, the lower end of which slidably extends through the bottom of the casing 53 and is fixed to the contact bar 56,
the terminals of which are adapted to contact with the plates 43 and 44 at certain times. As shown in Figures 1 and 3 the arm 15 is in contact wit-h the plate 10, the tension of the. spring 23 being suliicient to overcome the intake manifold eiand. a:p'artial vacuum is created in the cylinder 5 through the pipe 6, thus drawin the piston 7 outwardly against the tensi n ofthe spring 23. The retraction of the rod: 8.obviously. permits the arm 15 to flex, thus breaking; the circuit through said armtand plate 10. This operation, of course, deenergizes the magnets 32 and 33 whereupon the spring 57, mounted in the casings 53 and 5.4, will lift the armature 38 to elevate the bar -56,"instant'ly stopping the starting motor 45. It will beunderstood that as soon as the engine is in motion sufiicient suction is present in the cylinder 5 to pull the piston 7 rearwardl'y a suficient distance to Withd aw the arm 15 from contact with the plate 10, thus breakin the circuit'as long as the engine is running. bviously when the engine stops suction in the cylinder ceases,
' whereupon the spring 23- acts to move the arm 15 into contact with the platelO.
Having thus described the invention, I claim: v 1'. A circuit-breaker'offthe character described comprising a frame, contacts carried by said frame, one contact being movable towards and away from the other and normally remaining in engagement therewith,
