HAROLD D. CHURCH, OF DETROIT, MICHIGAN, ASSIGNOR TO PACKARD MOTOR CAR COMPANY, OF DETROIT, MICHIGAN, A CORPORATION OF MICHIGAN.
HYDROCARBON-MOTOR.
Application filed January 27, 1913.
To all whom it may concern:
Be it known that I, HAROLD D. CHURCH, a citizen of the United States, and resident of Detroit, \Vayne county, State of Michigan, have invented certain new and useful Improvements in Hydrocarbon-Motors, of which the following is a specification.
This invention relates to hydrocarbon motors, and particularly to the controlling mechanism thereof.
In hydrocarbon motors as used on commercial vehicles, it is desirable to positively limit the speed of the motor, preferably by automatically governing it. In the art' pre vious to this invention, it has been common practice to connect the motor throttle with the governor through various rods and links in such manner that any wear in the connections would tend to permit the throttle to open somewhat wider than the original setting and thus produce a greater speed of the motor than was originally intended. The speed at which these heavy vehicles should travel is very carefully calculated by the manufacturer, and as a rule the governor and throttle connections are housed and sealed so that the governor setting cannot be tampered with by the operator of the vehicle. It is of the utmost importance that the speed of the vehicle should be kept down to the calculated limit.
The principal object of the present invention is to so connect the governor with the throttle valve that wear in the connections will tend to relatively close the throttle instead of relatively opening it. This construction, therefore, tends to slow the ve hicle down rather than to speed it up when the parts become worn through constant use.
Other objects of the invention will be apparent from the following description, taken in connection with the drawings, which form a part of this specification, and in which,
Figure 1 is an elevation of a hydrocarbon motor intake pipe with an integral casing for the throttle arm, and the governor casing and governor therein, showing the corers of the casings removed and parts broken away; and
Fig. 2 is a sectional view of a detail.
Referring to the drawings, 10 represents a portion of the motor intake ipe with the blttclfly throttle valve 11 t erein. This throttle is operated by an arm 12 on the Specification of Letters Patent.
Patented June 25, 1918.
Serial No. 744,450.
outside of the intake pipe, and a second arm 13 is also connected to the throttle, and a spring 14 connected to the arm 13 tends to hold the throttle 11 yieldingly in closed position. These arms and the spring are housed in a casing 15, which is shown as integral with the intake pipe 10 and as having its cover removed. The cover is preferably bolted on to the casing in the well known manner by bolts passing through the holes 16.
A governor casing 17 is shown at the left in Fig. 1, and this casing may be mounted at any convenient point on the motor, or if desired it may be mounted on the gear box or other part of the vehicle in which the motor is used, so that the governor shaft can be driven by some part of the vehicle that rotates as the vehicle moves and at a speed relative to that of the vehicle. In the present instance, the casing is mounted adjacent the intake pipe and is connected thereto by a tube 18 which forms a conduit between the interior of the casing 17 and the interior of the casing 15, as will be clearly seen in the drawings.
The governor 19 may be of any well known type, a centrifugal governor being shown. This governor is mounted on a shaft 20 mounted in bearings 21 in the casing 17, and a gear 22 may be suitably connected with any driven part of the motor or vehicle for rotating the shaft 20.
From the above, it Will be seen that as the governor balls 23 are thrust outwardly by centrifugal force, the governor rod 24 is moved upwardly, and as the speed of the shaft 20 drops, the spring 25, connecting the governor balls 23, tends to draw the governor rod. 24 downwardly. The rod 24 is shown as mounted in a bearing 26 in which it both rotates and slides.
As shown in detail in Fig. 2, the upper end of the rod 24: bears downwardly against a disk 27 through a thrust bearing 28, a suitable abutment in the form of a nut 29 retaining the upper member 30 of the bearing 28 on the end of the rod. The disk 27 is formed with trunnions 31, which are engaged by theforked ends 32 of a bell crank lever 33. This lever is pivoted at 3-1 and is provided with an arm 35, which is connected through a link 36. with the arm 12 of the throttle valve, hereinabove described.
Again referring particularly to Fig. 2, it
will be seen that the upper end of the rodtrolling element of the governor, and the leverage of such spring is such that it will' overcome the tendency of the spring 14 to close the throttle 11. Therefore, when the motor is not running, the governor will be in the position shown in Fig. I andthe throttle will be moved to its wide open position, as shown therein in full lines. But the spring 14: is'always tending to close the throttle l1, and therefore all the lost motion in the joints between the link 36 and the arms 12 and 35 and in the connection between the bell crank lever 33 and the disk 27 is taken up by this spring 14:, and the valve is more or less closed relative to the position of the governor, depending upon the amount of play in these joints and connections.
From the above description, it will be seen that as the governor balls 23 fiy outwardly by reason of the rapid rotation of the shaft 20, the spring 25 will be overcome and the rod 24: will be moved upwardly.
As the rod 24 moves, the disk 27 follows it I by reason of the spring 14 tending constantly to move the horizontal arm of the bell crank lever 33 in an upward direction. This upward movement of the disk 27 permits the bell crank lever to rock and carry with it the link 36 and the throttle valve arm 12. As the link 36 Withdraws it permits the spring 14 to'close the throttle more and more as the shaft 20 speeds up. A consideration of Fig. 1 will show that if for any reason the spring 14 should fail the link 36 would still close the valve as the speed of the motor increased. In other words, there is a constant tendency on the part of the spring 14 to close the throttle, which tendency. is overcome by the spring 25 of the governor so long as the governor is at rest, but when the governor reaches a critical speed, it moves the rod 24 upwardly, and thereby permits the spring 14 to close the" throttle.
A specific embodiment of the invention has been described in detail, which embodiment is deemed to be new and advantageous and will be specifically claimed, but it should be understood that the invention is not limited to the exact details of construction shown, as it will be apparent that changes may be made without departing from the spirit and scope of the invention.
