Abstract
Abstract An ignition safety system for garden tractors, with an electric circuit including a battery, a generator, and an ignition coil. A plurality of electric switches are connected in the circuit, and a weight-responsive tractor seat has one of the switches thereunder for closing when the operator sits in the seat. There are two more of the said switches which are manually operated, preferably by keys, with one of the two switches being in series connection with the seat-operated switch, and with the other of the two switches being in parallel connection with the seatoperated switch to electrically bypass the seat-operated switch, all at the discretion of the operator.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
194 words
In an ignition safety system for a garden tractor, an electric circuit including a battery and a generator and an ignition coil and a plurality of electric switches controlling flow of electric current in said circuit, a tractor seat having a weight-responsive support for lowering said seat under the weight of the operator, a first one of said electric switches being responsive to the lowering of said seat to be electrically closed when said seat is occupied and to be electrically open when said seat is unoccupied, the improvement comprising all of said switches being separate devices and independently operative, a separate control member for each respective one of the other of said switches, said other of said plurality of switches being two normally open and manually operated switches and at all times all said switches being operative independent from each other, one of said manually operated switches being electrically connected in series with said first one of said switches, and the other of said manually operated switches being electrically connected in parallel with said first one of said switches and connected in said circuit to electrically bypass said first one of said switches.
Claim 2
Dependent Claim
194 words
In an ignition safety system for a garden tractor, an electric circuit including a battery and a generator and an ignition coil and a plurality of electric switches controlling flow of electric current in said circuit, a tractor seat having a weight-responsive support for lowering said seat under the weight of the operator, a first one of said electric switches being responsive to the lowering of said seat to be electrically closed when said seat is occupied and to be electrically open when said seat is unoccupied, the improvement comprising all of said switches being separate devices and independently operative, a separate control member for each respective one of the other of said switches, said other of said plurality of switches being two normally open and manually operated switches and at all times all said switches being operative independent from each other, one of said manually operated switches being electrically connected in series with said first one of said switches, and the other of said manually operated switches being electrically connected in parallel with said first one of said switches and connected in said circuit to electrically bypass said first one of said switches.
Claim 3
Dependent Claim
35 words
The subject matter of claim 1, wherein said two manually operated switches are key-operated switches, and said control members for said two manually operated switches are two keys for operating said two manually operated switches.
Claim 4
Dependent Claim
87 words
The subject matter of claim 2, wherein said two keys are structurally different relative to each other by having different arrangements of teeth, and said two manually operated switches are structurally different relative to each other, with one of said two manually operated switches being operative only in response to the use of only a respective one of said two keys, and with the other of said two manually operated switches being operative only in response to the use of only the other of said two keys.
Claim 5
Dependent Claim
56 words
The subject matter of claim 2, wherein said two keys are structurally the same relative to each other by having the same arrangement of teeth, and said two manually operated switches are structurally the same relative to each other, with both of said manually operated switches being operative in response to each of said two keys.
