Specification of Letters Patent.

' Serial No. 411,073.
. which the following is a specification.
' the miles travele connected with my invention to an electric My invention relates to improvements in devices for limiting the speed of electrically ignited explosive engines; and the object of my improvement is to prevent such an engine, or vehicle propelled thereby, from exceeding a desired speed.
This specification is a division'of my application for a similar device, .filed January 9, 1907, Serial No. 351,489.
I attain my object by the mechanism and electric circuits illustrated in the accompanying drawing, in which:
A vertical section of a s eed indicator, commonly used u on vehic es to indicate per hour, is operably ally ignited explosive engine.
he numeral 1 is a sectional view of a speed indicator operated by centrifugal force by means of a flexible shaft 2 which extends any desired length and has a small pinion attached'to its extreme end (not shown in drawing) that meshes with a gear upon the vehicle wheel, or engine shaft, which causes the flexible shaft 2 to revolve at a s eed proportional to the speed of the whee ,.or
engine shaft, and swing the weights 15 and 16 at a s eed necessary to raise them by centrifuga force against the tension of the spring 17 and cause the index 4 to rise upont e scale 3 and indicate the number of miles the vehicle is traveling, or the speed of the engine shaft, according to the divisions upon the scale 3.
5 is a flexible contact normally touching a shorter contact 6 and both attached to an insulated terminal that is adapted to be clasped upon the frame of the indicator, at
any point of the scale, with the longer contact 5 in the path of the index 4 ,10 indicates a battery, or source of electricity; 7 is .a
switch; .8 represents an induction coil; and i 9 representsan-ex losive engine. 11;, 12, 13 and 14 are meta ic electric circuits connectmg the different apparatus.
gines it is necessary to have an electric spark produced in the cylinder at the proper time to ignite-the mixture of gases, and to latedoint 19 when the cam 18 upon the engine s aft raises the movable contact and causes the two to meet, thence through "the wire 11' to contact 5, contact 6 and by the wire 12 back to the battery, 10,forming a and 6 and the coil 8.
When the cam 18 passes by the movable contact upon the en ine and allows, it to the current through the primary winding of a momentary current of high potential is induced in the secondary winding of the coil 8 that flows through the wire 14 to the spark plug 20 in the engine, and jumps across the gap in the lug to the frame of the engine, thence by tiie'vire 13 completing the circuit of high potential, and producing a spark within the cylinder at the proper time to ignite the gases, and operate the engine. This spark of ignition is produced at each separation of the movable contact from the point 19 and causes the continuous operation of the engine until the circuit from the battery is broken by opening the switch 7 or se arating the contact points 5' and 6.
f the terminal su porting the contacts 5 and 6' is clamped to t e frame of the indicator so that the longer contact 5 covers the figure indicating a speed of fifteen miles er hour, and theengine is pro elling the ve icle at a speed below fifteen miles per hour, the index 4 will not rise so as to reach the contact 5; but should the speed be increased, until a s eed of fifteen miles is reached, then theineX- 4 will meet the contact 5 and separate it i from the contact 6, open the primary circuit through the coil, prevent a high potential 2 current from bein induced in the secondary produce this spark requires a source of complete circuit through the two contacts 5 separate from the insu ated contact" point 19 the induction coil 8 is suddenly broken, and
In all electrically ignited explosive en- 1 wiring of the co' 8, stop the spark in the 1 10 cylinderand deprive the engine of its power until it slows down sufficiently to allow the contacts 5 and 6 to come together and close the primary circuit through the coil 8, thus reproducing the spark in the engine and causing it r 0 continue in operation. By this means the engine will be enabled to kee an ap roximate s eed of fifteen miles per our an I revente from exceedin this speed, thus imiting the speed of an e ectrically ignited ex losive engine.
What% claim as my invention and desire to secure by Letters Patent, is
1. In an electrically ignited explosive enine; a primary electric circuit; means for interrupting the primary circuit consisting of a speed indicator; and a movable index; contiguous contact points, closing the primary circuit, adapted to be set at any point upon ei eie tor.
2. In combination with an instrument having a movable index and a scale for indicating the speed of a vehicle propelled byan electrically ignited explosive engine; contiguous contact points closing a primary electric circuit, adapted to be set at any point upon the instrument scale; the index of the instrument separating the contact points to open the primary circuit.
Signed at the city of New York in the county of New York and State of New York this 14th day of January A. D. 1908.
