Abstract
Abstract A speed indicating device is provided which may be adjusted to indicate a maximum and a minimum speed as the vehicle is in motion. A pair of switches or contacts are provided which indicate maximum and minimum speeds which may be perhaps ten miles per hour different. A fan or propeller actuates an arm which will oscillate between contacts depending upon the vehicle speed. However, the contacts are adjustable through operation of the arm. The normally fixed contact support may be released, so that the vehicle speed may be increased to a predetermined maximum, and then the contact support may be locked to provide an indication when the desired speed is exceeded.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
121 words
A vehicle speed indicating device including: a rotatable member actuated by air pressure the rotative position of which is dependent upon the speed of movement of the vehicle, a shaft supporting said rotatable member and rotatable therewith, a hub secured in fixed relation to the vehicle and through which said shaft extends; a control arm secured to said shaft and extending generally radially therefrom, a contact member rotatably supported on said hub coaxial with said shaft, circuit actuating means operable by engagement of said control arm with said contact member, means normally holding said contact member from rotation, and driver controlled means for releasing said last named means, whereby when said control arm engages said contact member it may rotate therewith.
Claim 2
Dependent Claim
121 words
A vehicle speed indicating device including: a rotatable member actuated by air pressure the rotative position of which is dependent upon the speed of movement of the vehicle, a shaft supporting said rotatable member and rotatable therewith, a hub secured in fixed relation to the vehicle and through which said shaft extends; a control arm secured to said shaft and extending generally radially therefrom, a contact member rotatably supported on said hub coaxial with said shaft, circuit actuating means operable by engagement of said control arm with said contact member, means normally holding said contact member from rotation, and driver controlled means for releasing said last named means, whereby when said control arm engages said contact member it may rotate therewith.
Claim 3
Dependent Claim
25 words
The structure of claim 1 and in which said rotatably supported contact member includes a pair of members between which said control arm may rotate.
Claim 4
Dependent Claim
21 words
The structure of claim 2 and including resilient means urging said control arm in one direction against one of said members.
Claim 5
Dependent Claim
22 words
The structure of claim 2 and including signal means controlled by engagement of said control arm against either member of said pair.
Claim 6
Dependent Claim
22 words
The struCture of claim 1 and in which said means normally holding said contact member from rotation comprises a spring urged plunger.
Claim 7
Dependent Claim
15 words
The structure of claim 5 and in which said spring urged plunger is solenoid actuated.
Claim 8
Dependent Claim
16 words
The structure of claim 1 and in which rotation of said rotatable member is resiliently resisted.
Claim 9
Dependent Claim
20 words
The structure of claim 1 and including signal means controlled by engagement of said control arm with said contact member.
Claim 10
Dependent Claim
14 words
The structure of claim 1 and in which said contact member includes a disc.
Claim 11
Dependent Claim
18 words
The structure of claim 9 and in which said disc supports a pair of angularly spaced switch means.
