Abstract
Abstract One or more support plates are secured to frame portions of a motor vehicle each in proximity to one of the wheel suspension systems of the vehicle. Hingedly mounted on each support plate is a control plate. Each control plate has a free end positioned to coact with a portion of the wheel suspension system (wheel balancer, upper or lower control arm, shock absorbers, springs) and more particularly that portion of the wheel suspension system which will drop or move downwardly when the vehicle is jacked up in preparation to remove a tire. A mounting bracket is adjustably carried by each support plate in proximity to the control plate hingedly carried thereby. An electrical switch is positioned on each mounting bracket with the operating element for its contacts positioned for coaction with its respective control plate to be operated thereby in response to movement of the associated movable portion of the wheel suspension system. Each switch is, in turn, electrically interconnected in a circuit with electrical power and an alarm device such that switch actuation will sound the alarm in response to the raising of the vehicle in preparation to remove one or more of its tires. The electrical power and alarm device can either be the vehicles own battery and horn or separate battery power and noise making device.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
183 words
An alarm actuating device for indicating the removal of part of a motor vehicle comprising: a. a mounting plate; b. a control plate swingably mounted on said mounting plate for swinging movement between a first predetermined position and a second predetermined position; c. a mounting bracket having a first leg adjustably positionable on said mounting plate and a second leg positionable along with said first leg in relation to said control plate; d. electrical switch means carried by said mounting bracket and having a pair of contacts adapted to be selectively opened and closed; and e. a switch contact actuating member disposed for coaction with said pair of contacts of said switch means to either maintain same spaced apart or permit same to close; f. said switch contact actuating member further being disposed for co-operation with said control plate in said first predetermined position of said control plate to maintain said pair of contacts spaced apart, and in second predetermined position of said control plate to permit said pair of contacts to close to indicate the removal of part of a motor vehicle.
Claim 2
Dependent Claim
183 words
An alarm actuating device for indicating the removal of part of a motor vehicle comprising: a. a mounting plate; b. a control plate swingably mounted on said mounting plate for swinging movement between a first predetermined position and a second predetermined position; c. a mounting bracket having a first leg adjustably positionable on said mounting plate and a second leg positionable along with said first leg in relation to said control plate; d. electrical switch means carried by said mounting bracket and having a pair of contacts adapted to be selectively opened and closed; and e. a switch contact actuating member disposed for coaction with said pair of contacts of said switch means to either maintain same spaced apart or permit same to close; f. said switch contact actuating member further being disposed for co-operation with said control plate in said first predetermined position of said control plate to maintain said pair of contacts spaced apart, and in second predetermined position of said control plate to permit said pair of contacts to close to indicate the removal of part of a motor vehicle.
Claim 3
Dependent Claim
46 words
The alarm actuating device of claim 1 wherein a source of power and an alarm device for producing an audible sound are interconnected by electrical circuit means to said pair of switch contacts such that said alarm device is energized when said pair of contacts close.
Claim 4
Dependent Claim
18 words
The alarm actuating device of claim 1 wherein the source of power is a battery source of power.
Claim 5
Dependent Claim
16 words
The alarm actuating device of claim 1 wherein the alarm device is a motor vehicle horn.
Claim 6
Dependent Claim
113 words
The alarm actuating device of claim 1 wherein a. said mounting plate is to be secured to the frame of a motor vehicle, in proximity of one of the wheel suspension systems provided therewith, and in such a manner that said control plate co-operates with a portion of the wheel suspension system which will move with respect to the vehicle frame when the vehicle is being raised up; b. said first predetermined position of said control plate being when said suspension system is positioned when the vehicle is not raised up and second predetermined position of said contact plate being when said suspension system is positioned when the vehicle is being raised up.
Claim 7
Dependent Claim
23 words
The alarm actuating device of claim 5 wherein said control plate is mounted on said mounting plate by a pair of spaced hinges.
Claim 8
Dependent Claim
46 words
The alarm actuating device of claim 6 wherein said mounting bracket is adjustably positioned on said mounting plate by passing a bolt through an aperture in said first leg and through an elongated slot in said mounting plate and securing same in place by a nut.
Claim 9
Dependent Claim
66 words
The alarm actuating device of claim 7 wherein said electrical switch means is mounted on an upper surface of said second leg of said mounting bracket and said switch contact actuating member is a plunger which extends from said switch means through an aperture in said second leg of said mounting bracket down towards and into contact with said control plate which is hingedly mounted therebelow.
Claim 10
Dependent Claim
47 words
The alarm actuating device of claim 8 wherein a pair of pressure members are disposed beneath said second leg of said mounting bracket in proximity of said plunger and for coaction with said control plate to restrict movement of said control plate towards said second leg thereof.
Claim 11
Dependent Claim
52 words
The alarm actuating device of claim 9 wherein a mounting plate, mounting bracket, control plate, and electrical switch means are provided for each wheel suspension system of a motor vehicle, and electrical connection means are provided to interconnect all of said electrical switch means to the source of power and alarm device.
