SELECTEDSPEED REGULATOR Filed April 10, 1937 Emma kw Gnu/M43 Patented Sept. 6, 1938 UNITED STATES PATENT OFFICE 2 Claims.

This invention relates to the class of motor vehicles and pertains. particularly to a novel means of controlling the speed of the same.

The present invention has for its primary object to provide a novel device designed for application to a motor vehicle, by means of which the maximum speed at which the vehicle may be operated may be set upon a locked control so that persons operating the vehicle will be pre- 1 vented from running the same at a greater speed than is desired by the person responsible for the vehicle.

Another object of the invention is to provide in association with a fuel intake regulator adapted to be attached between the vehicle engine intake manifold and carbureter, a control unit which is adapted to be disposed in a position in the vehicle convenient for setting by the operator of the vehicle and coupled with the fuel intake regulating means whereby when the control is set to indicate a desired maximum speed for the vehicle, it may be locked to prevent unauthorized persons changing the speed.

A further object of the invention is to provide a lock controlled motor Vehicle mechanism speed regulator which is of simple but rugged construction and which may be inexpensively manufactured and easily and quickly applied to a motor vehicle.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawing forming part of this specification, with the understanding, however, that the invention is not confined to any strict conformity with the showing of the drawing but may be changed or modified so long as such changes or modifications mark no material departure from the salient features of the invention as expressed in the ap- 40 pended claims.

In the drawing:

Figure 1 is a view illustrating in vertical section a portion of a motor vehicle engine intake manifold pipe and a carbureter coupled therewith,

4.5 showing the device embodying the present invention inserted between the carbureter and manifold and showing in elevation the control means for the device.

Fig. 2 is a view in elevation of the rear of the 50 control panel for the device.

Fig. 3 is a sectional view taken on the line 33 of Fig. 1.

Referring now more particularly to the drawing the numeral I generally designates a portion of 55 the intake manifold of a motor vehicle engine to which is attached in the usual manner the outlet 2 of a carbureter. The coupling between the carbureter and the intake manifold is usually effected through the medium of bolts 3 which are passed through the adjacent spaced ears or 5 flanges 4 which form. integral parts of the carbureter and manifold units.

The device generally comprises the two units 5 and 6 which are coupled together by a Bowden wire which is indicated generally by the numeral 10 1. The unit 5 constitutes the control valve and consists of the two plate members 8 which are interposed between the bolt connected flanges 4 and which have their opposing faces cut out to form a slide chamber 9 in which the shut-off l5 slide valve Ill is positioned. The plates 8 are provided with alined openings II which, when the plates are in position between the flanges 4, are concentric with the fuel passageways I and 2 and the slide valve Ill when moved inwardly in 20 the chamber 9 is adapted to close the openings I I so as to shut off the passage of fuel to the engine. The plates 8 are provided with the lateral integral extensions I2 which have their opposed faces recessed as indicated at I3, and these re- 25 cesses merge with the recessed portions of the plates so as to receive the shut-off valve I0 when it is drawn outwardly to open the fuel passage. The Bowden wire I which consists of the usual flexible casing portion I4 and the wire I5, has 3 one end of the casing secured between the extended portions I2 of the valve unit as illustrated in Fig. 3, and the. adjacent end of the wire I5 connected with the slide valve I0 as here shown.

The control unit which is indicated generally by the numeral 6, is placed within the motor vehicle at some point convenient to the operator so that the mechanism speed for operating the vehicle can be changed conveniently. This unit consists of a plate or panel IE in which a window I1 is formed, and secured to the back of the panel across the window I! is a plate I8 upon the face of which a scale I9 is placed which is arranged to be seen through the window I'I when viewing the panel IB from the front.

Below the plate IS the panel has rotatably secured thereto a shaft 20 which passes through and has secured thereto the wheel 2| in the periphery of the lower half of which is formed a series of notches 22. This wheel carries a pointer 23 which extends upwardly between the plate I8 and the window opening H, the plate I8 being suitably spaced from the panel IE to permit the pointer or needle 23 to move freely when the wheel 2I is rotated. 5

The wheel M has attached thereto the crank arm 24 to the free end of which the other end of the Bowden wire i5 is connected, and the other end of the casing M is secured to a block 25 which is mounted transversely of the lower portion of the panel H3 upon the back of the latter. This block 25 supports a lock nut which is generally designated 26, and may be of any suitable type, preferably the type in which there is a key-controlled rotatable barrel 2'3 upon the inner end of which an eccentric disc 28 may be secured. This disc 28 upon the inner end of the lock barrel positions in the elongated slot 29 formed in a follower 3B which is slidably mounted in a recess 3! in the block 25, and this slide carries a latch finger 32 which, when the slide is moved to the upward limit of its path of travel, will engage in one of the notches 22 of the wheel 2|. By this means the wheel can be secured in any set position, and when the lock securing means is released the necessary rotary motion can be imparted to the wheel 25 by the knob 33 which is disposed at the front of the panel !6 and mounted upon the shaft 29 to which the wheel is secured.

From the foregoing it will be readily apparent that when the device embodyingthe present invention is installed, it will be initially set or adjusted so that when the needle 23 is moved tothe extreme left position the fuel control slide valve ill will be in a position to close the fuel passage between the carbureter and the intake manifold. Then by rotating the wheel 2! the needle may be set to 48, 553, or 60, or any of the other speed indications shown on the dial so that the valve plate H3 will be drawn outwardly a sufficient distance to allow only enough fuel to pass into the intake manifold to effect the operation of the engine at the speed designated by the needle. After the needle has been set to the desired speed position, then it may be secured by the operation of the lock nut 25 so as to secure,

through the medium of the securing finger 32, the
