Description

Patented Dec. 1-, 1925. i
1,563,670 PATENT" OFFICE.
LEON G. SPENCER, 01E: OGDEN, UTAH,
ELECTROMAGNETICALLY-OPERATED STARTER SWITCH.
Application filed June .10, m4. Serial in 719,155.
To all whom it may concern.
, Be it known that I, LEON C. SPENCER, a.
citizen of the United States, residin at Ogden, in the county of \Veber and tate of Utah. have invented certain new and useful Improvements in Electromagnetically-Operated Starter Switches; and I do hereby declare the following to be a full,
clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. a
This invention provides an electric switch for controlling the starter current of a motor vehicle, said switch being included in an "electric circuit containing a push button, which when operated effects automatic operation of the starter switch to close the starter circuit, thereby dis nsingwith the ordinary foot operated switch whereby the starter circuit is usually closed. I
Other objects and advantages will be apparent and suggest themselves as the nature of the invention is understood.
While the drawing illustrates an embodiment of the invention it is to be understood that in adapting the same to meet different conditions and requirements, various changes in the form, proportion and minor detalls of construction may be resorted to w1th out departing from the spirit of the lnvention.
Referrlng to the accompanying drawings forming a part of the application: Figure 1 is an elevational view of an electric switch embodying the invention, the housing being in section;
Figure 2-is a view similar to Figure 1,
' partly in section; and
Figure 3 is a sectional View on line 3-3 of Figure 1.
Corresponding and like parts are referred to in the following description and designated in the several views of the drawing by like reference characters.
The switch is mounted upon a base plate 1 and the operating arts are enclosed by a housing 2 which is etachably connected to the plate 1. Studs 3 project from the base plate 1 and support a plate 4 which is attached thereto. An approximately U- shaped frame 5 is mounte centrall upon the )late 4 and the upper ends of its side mem ers are inturned to enga e and form a uide for an armature 6 whic 1 as shown is fiat'and of circular outline. Arms 7 extend starter circuit.
5 and its core has an axial opening 11 through which the post 9 passes freely. The post 9 is of non-magnetic material such as rass and is threaded to make'adjustable connection with the plate l and adjustably support the armature 6.
Contacts 12 and-13 are mounted upon'the base plate 1 and are electrically insulated therefrom. The starter circuit includes the contacts 12 and 13. A circuit closing. member 14 co-acts with the contacts 12 and 1.3 andis attached to a stud 15 which is loosely mounted in the base plate 1 and which is of non-circular outline to prevent turning of the member-14 and insure its pro er coaction with the contacts 12 and 13. light spring 16 mounted upon, the stud 15 normally holds the member 14 clear of the contacts 12 and 13. The starter portion of the circuit closing member 14 is disposed in line .with the post 9 and when the electromagnet 10 is energized and the armature 6 attracted the member 14 is advanced and engages the contacts 12 and 13 thereby closing the One terminal of the winding of the electro-magnet 10 is grounded to the base plate 1' as indicated at 17 ,and
the other terminal is electrically connected,
to a binding post 18 mounted upon the base plate 1 and electrically insulated therefrom. The electromagnet is included in a circuit which is controllable by means of an ordinary push button which when pressed upon closes the circuit including the electro-magnet 10 and the latter in turn becoming energized, automatically closes the starter circuit in the manner stated.
What is claimed is y 1. An electric switch com rising circuit closing elements including a ridging member yieldingly held from enga ement with contact members, a substant1ally U-shaped frame having the ends of its side members inturned, an electromagnet mounted upon said frame and having an opening through its core, an armature directed in its move ments by the inturned ends of the said frame, an element connected to said armature and passing through the opening of the core of the electromagnet and adapted to actuate said bridging member into engagement with the contact'members.
2. An electric switch com rising circuit closin elements including a Eridging member y1elding1 held from engagement with contact mem'ers, a supporting frame, an
electromagnet mounted upon the frame and upon the said post.
3. An electric switch comprising a base plate, circuit closing elements associated therewith, a substantially U-shaped frame 20 mounted upon the plate and having the ends of its side members inturned, arms'extending from the side members of the frame, a flat spring attached to the said arms, an electromagnet mounted upon the frame and having an openingithrough its core, a post having' adjustable htinnection with the said fiat spring and passing loosely through the opening in the corefof the electromagnet, and an armature adjustably mounted upon the post and disposed between the inturned terminals of the said frame.
