. lThe subject matter of this applicationV was Y-jfound in an application filed by us on Sep- V tember 14, 1928, Serial No.'306,087-, for signaling devices, and was divided out of that application. A `This invention relates-'to signaling switches which may be used in variousV signaling devices of the general type disclosedin our application Serial No. 243,499,131@ December 30, 1927, for signaling devices for automobiles.

The object of the invention is to provide an improved signaling switch for use in connection with signaling mechanism. Another object is the provision of a signaling switch which is adapted to be connected to an accelerator rod or the like on an automobile, and is adapted to close and open a circuit during one continuous movement in one direction of the accelerator rod. Another object is the provision of a device which is simple in construction and operation, and is highly eliicient'for the purposes enumerated.V

Other objects and advantages will appearV more fully in the following specification when taken in connection with the accompanying drawing in which:

Fig. 1 is a view partly in section and partly in elevation showing one embodiment of our invention;

Fig. 2 is a sectional View taken substantially on the line 2 2 of Fig. 1; and

Fig. 3 is a detail view of the contact e-ngaging jaws of our device, and is taken substantially on the line 3&3 of Fig. 2.

Referring now to the drawing, our device is provided with a casing 5 having an integrally formed depending tube 6, in which is inserted stem 7 having shoulder 8, and which may be provided at one of its ends with an j insulating collar 9, which has an enlarged bead 10. Collar 9 is held on stem 7 by flattened portion 11. Intermediate the ends of stem 7 is provided a coil spring 12, which is adapted to impinge upon the base of collar 9 at one end of said spring, and upon the wall of casing 5 at its other end.

Upon the walls of casing 5 may be mounted binding post 13 and insulated from casing 5 by means of insulation 14. To one of saidY binding posts is secured a U-shaped member V15 formed into a .pairrof resilient jaws 16.

As is illustrated more clearly in Fig. 3, jaws 16 are arcuate in shape, and are adapted to receive a blade/or rod betweenthem; sincetv jaws 16 are in an oppositely disposed relation, the rod may be inserted between them with equal facility from the upper and lower ends of jaw I16. l

Y To the other binding post 13 maybe secured a coiled resilient contact member 17 having formed intermediate its ends a ring '18, which `slidablyengages collar 9, Vand is limited from any furtherupwardwmovement on collar 9 by bead 10. At the freeend of `member 17 is'provided'a rod-'like eXtension 19. Y

1n operation, stem 7 may be` connected to the accelerator stem of an automobile, and

by appropriate electrical connections, binding posts 13 may be securedto a' Wire leading to a signaling device;v When the accelerator rod is depressed, stem 7 will be pulled outwardly through depending tube 6, and when this isdone, contact member 17 will be drawn l downwardly by Vbead 10 on collar 9, and will pullv rod-like extension 19` into engagement by jaws 16. y

When further pressure isapplied tothe acbroken. When the tension on stem 7 is ref.Y I

leased, coil spring 12 by impinging upon the base of collar 9, willforce the stem upwardly, and the tension of coiled Contact member 17 will cause extension 19 to slide upwardly through jaws. 16, and out of contact withsaid; A

jaws. v It is of vcourse understood*thatcertainvariations may' be'ma'de without" departing vfrom' the scope oit 'ourinve'ntiom and hence "we do not wishto be limited tothe precise des.;

celerator', extension 19wil1 be drawn free otr-'S0 I v ber having a ring intermediate its ends, said pair of jaws supported by the other of said` binding posts, said jaws being adapted to engage clampingly said resilient element when it is drawn between said jaws, and means for maintaining normally said resilient element out of engagement by said jaws.V

2. In a signaling switch a casing having a projection, a member slidable kwithin said projection, binding posts mounted within said casing, amember mounted on one of said binding posts and engageable with the aforesaid1 slidable member, and ineansfor clampingly engaging said member supported by the other of said binding posts, Vsaid switch being adapted to close and open a circuit during one continuous rectilinear movement of said slidable member. Y

3. In a device of the character described, a casing having an integrally formed tubular projection, a rod slidablly mounted in-said tubular projection and provided at one of its ends with a collar having an enlarged beadk portion, binding posts mounted on the walls of said casing, a resilient contact member mounted on one of said binding posts and provided intermediate its. ends with a ring adapted'to engage said collar, said resilient contact member also being providedwith a rod-like extension, and a Uf-shaped member providing a pair of jaws mounted on one of jsaid binding posts, said jaws being adapted to Aengage clampingly the extension of said resilient contact member.

4. A device of the character described comprising a casing having a wall adapted to reenlarged bead secured to said rod, binding posts secured to the walls of said casing, a resilient Vcontact element having a ring intermediate its ends and secured to one of said binding posts, said ring being adapted to embrace said collar and impinge upon said bead ywhen said rod is withdrawn partially .from saidl casing, and a pair of jaws secured to one of said binding posts, said jaws being adapted to engage clampingly said resilient contact member when said rod is withdrawn par- -tially from said casing.

6. In a signaling switch, a casing having an aperture therein, a member slidable through said aperture, binding posts within said casing, a spring member mounted on one of said binding posts and lslidably yengaging said slidable member, kand means for clampingly engaging said vspring member supported by the other of said binding posts.

In testimony whereof we have signed our names to this specification.
