9 Claims.

My. invention relatesy to new and useful improvements in automatic speed control meansI for automotive vehicles.

An important object of my invention is to provide a device for controlling and regulating the maximum speed of an automotive vehicle.

Another object of my invention is the provision oi a device of the above-mentioned character that is automatic in its action to permit a greater quantity of fuel to be injected into the carburetor when the vehicle is rapidly accelerating below the maximum speed for which the device is set.

Still another object of my invention is the provision of a device of the above-mentioned character that will automatically permit a greater quantity of fuel to be injected into the carburetor when the vehicle is ascending an incline.

Yet another object of my invention is the provision of a device for controlling and regulating the speed of an automotive vehicle that may be effectively operated independently of the conventional throttle valve of the vehicle and that will in no Way interfere with the actuationor operation of the same.

A further object of my invention is the provision of a device of the above-mentioned character that may be readily and expeditiously applied to vehicles already manufactured and in use.

A yet further object of my invention is the provision of a device of the above-mentioned character that is simple in construction and that is eicient and efficacious in the performance of its duties.

Other objects and advantages of my invention will be apparent during the course of the following description.

Figure 7 is a perspective View of another link member embodying a part of my invention.

In the accompanying drawings, wherein for the purpose of illustration, is shown a preferred embodiment of my invention, the numeral I designates the carburetor of an automotivey vehicle having the conventional gas feed line II, throttle actuating lever I2 and lthrottle rod I3. The carburetor is formed With a lower flange I4 normally registerable with the flange I of the intake manifold I6 and which is adapted tobe connected thereto by means of threaded bolts 23, or the like.

The numeral I'I designates a casing adapted to house the working parts embodying my invention. The casing includes a substantially cylindrical vertically disposed sleeve portion I8 havingl upper and lower peripheral flanges I9 kand 2U adapted to register with the flanges I4 and I5 of the carburetor and intake manifold respectively. The flanges I9 and 20 are substantially diamond-shaped in plan and are provided adjacent the ends thereof with openings 2l and 22 ladapted to align with openings in the flanges which integrally connects the same with `the sleeve. The Wall 24 includes aV peripheral flange 21 which defines a central horizontally disposed chamber 2K8 which is enlarged at the end 29 thereof to form a chamber 38 laterally of the sleeve I8.

The forwardly extending portion 25 of the wall is substantially circular in planand the flange 21 defines an enlarged cupular chamber 3| the lower portion of which communicates directly with the central passage 28. The flange 21 is provided at spaced intervals therearound with lugs 32 having threaded recesses 33 therein adapted 'to register with the openings 34 in the front cover 35 and to receive the threaded bolts 36 which hold the cover securely in place.

` The pintle 43 is positioned transversely of the vertical passage 31 of the sleeve I8 with ythe end 38 thereof journaled in the recess` 39`forrned in the inner wall of the passage and with the end 40 thereof extending through the sleeve I8 and into the chamber 30 to receive the lever arm 4I.

A throttle valve 42 is positioned within. the passage `3l and is suitablyfastened to the pintle 43.

Thesubstantially disk-shaped pendulum o-r weight 44 is positioned in the chamber 3| and pendulously mounted on the boss 45 integrally formed on the wall 24. The lower portion of the disk is stepped outwardly as at 4S to greatly increase the weight of the lower portion of the pendulum,l and an abutment 41 is formed on its lower periphery to engage the stop member 48 preferably integrally formed on the inner periphry of the flange 21, as illustrated in Figure 2. The stop member 48 engages the abutment 41 to hold the weight slightly olf center in the direction of the throttle valve 42 in order to normally assure the engagement of the abutment therewith, and the upper portion of the pendulum is provided with a plurality of arcuately spaced openings 49 to permit adjustment of the saidV i pendulum relative to the stop 48.

The companion link members 5|! and 5| are joined for longitudinal adjustment Vrelative to each other, and the end 52 of the link4 5|)` is pivotally connected to the pendulum adjacent the lower periphery thereof and at a point diametrically opposed to the middle opening 49. The end 53 of the link 5| is provided with spaced extensions 54 and 55 which slidably receive the pin 56 extending outwardly from the free end of the lever arm 4|. The end 51 of the link member 5|] is provided with an elongated slot 58 which slidably receives the pin 59 carried by the link 5| and the end E0 thereof is provided with a vertical slot 6| which receives the pin 56 of the lever arm 4| to securely hold the same between the extensions 54 and 55 of the link member 5|.

When the device is interposed between the carburetor |0 and intake manifold IB, as illustrated in Figure l, the throttle valve 42 may be positioned within the passage 31 to control the flow of fuel from the carburetor to the intake manifold; the throttle of the carburetor may be actuated in the conventional manner to control the flow of fuel therethrough. By adjusting the link members 50 and 5| relative to each other, the lever arm 4| may be acted upon to selectively position the throttle valve 42 for control o-f the vehicle at different predetermined speed limits. The heavy lower end of the pendulum 44 will assure the engagement of the abutment 41 with the stop 48 tol normally hold the valve 42 in the selected position and to prevent an excess of gas from flowing through the passage 31 and into the intake manifold, thus effectively and efficaciously controlling and regulating the maximum speed of the vehicle.

When the vehicle is being rapidly accelerated, the inertia of the weighted pendulum 44 will cause the same to swing toward the throttle valve 42 and to move the same to a relatively open position, thus permitting a greater quantity of fuel to be injected by the carburetor into the intake manifold. When the forward impetus of the vehicle has been checked and the vehicle is traveling at an even rate of speed, the heavy lower portion of the pendulum will cause the abutment 41 to once more engage the stop member 48 for control of the vehicle. 'I'he pendulum will be similarly actuated when the vehicle is ascending an incline. The engine will require a greater quantity of gas and the pendulum will swing in the direction of the valve to open the same and to permit the carburetor to discharge a ciously control and regulate the maximum forward speed of the vehicle.

It is to be understood that the form of my invention herewith shown and described, is to be taken as a preferred example of the same, and that various changes in the size, shape and arrangement of parts may be resorted to without departing from the spirit of my invention, or the scope of the appended claims.
