HAROLD D. CHURCH, OF DETROIT, MIQHIGAN. ASSIGNOR TO PACKARD MOTOR CAR COMPANY, 0F DETROIT, MICHGAN. A CORPORATION 0F MICHIGAN.
HYDROCARBON-MOTOR.
Specification et'V Letters Patent.
Patented May 14, 1918.
lie it known that, I, HAROLD I). Unomat, a citizen ot' the United States, and resident ol'- Detroit, Wayne county, State of lVlit-higait;l have invented certain new and useful Im- ]irovcmrnts in Hydroearbou-Motors, of which the following is a specification.
This invention relates to hydrocarbon motors and particularly to the control thereof. f
It is customary in most motors used in commercial motor vehicles or trucks to empwy a. governor to prevent excessive speed of the motor and thus of the truck, lVith the f fovernorsl as generally used there is f sometimes a hunting tendency due to the inertia of the governor closing the throttle valve too quickly and then opening it again as the speed goes down. It is one of the objects of the present invention to obviate this difficulty and provide a governor mechanism that will be smooth in its action and which will also permit a slight excess of speed and consequently of power for a limited time above the normal maximum limit to which "the governor is set. One form of the invention. is shown and described in this a )plieation but it will be understood that this form is illustrative only und that various changea therefrom and modifications thereof may be made without deparb ing from the Spirit or scope of the inven tion.
'Ihe above and other objects of the invention will appear from the following description taken in connection with the drawings which form e part hereof, and in which:
r Figure l is a vertical sectional view through a. governor mechanism and motor4 iutaketpipe, embodyingr the invention;
'Fig'. 2 is. a plan view ofthe governor mechanism shown in Fig. 1 with part of the cover eut away;
y Fig. 3 is a transverse section looking up, on the line 3,-3 of Fig. 1; and
Figs. 4 and 5 are detail views.
Referring to the drawings, 10 representsi the intake pipe of a hydrocarbon motor, and 11 is a throttle valve therein. the valve shown beingr of the butterfly type. Arrangrrdin series with the valvtl ll in'a `aimilar valvtl l2, and it willlal umh-.rattled that either of these valves may entirely close the intake pipe 10 and that when o. of' them is open, tie other may control the passage of f lrasthrough the intake from the maximum te? the minimum au'lount.
The valve l1 is arranged to be operated b v hand as through an arm llt and a rod il, while the valve li is adapted to -lle |governor controlled through the arm 1T. link lt and bell crank 17.
vThe governor casing lts' is adapted to be suitably mounted upon the motor. preterably in proximity to the intake pipe 1t) so thatthe connections 15. lt' and 17 may be, as Simple as possible, and its rotatable shaft 19 is adapted to lie driven by the motor through `suitable gearing including the gear Q0. The Shaft l!) is shown as hollow orof tubular form and has a sleeve lil secured upon its upper end as by a nut t9. .kn op-` erationr rod 21 paseos througl'i the .shaft l!) and is provided with a crosaI pin 22 which slides in slots 23 arranged for it in tlu` sha l`t. 19 and sleeve i9. The sleeve also has lugs 24 upon Which are pivotally mounted as at :7.5, the ball members 26 of the governor. One or more springs '27 draw the weighted ends of the ball membersl QG toward nach other into the rest position in which they are shown in Figi. 1 of the drawings, 'lhe inwardly extendingr arms 2S of the ball mem` bers are formed with yoke ends 29 which ro operate with the cross; pin 2.2 to movi` the operating rod 2l longitudinally as the gov ernor ball members Qt, change their position duoa tio centrifugal t'orei as the shalt l!) i. rotated.
lWeansy for adjusting the tension ot the governor springs QT. are provided in the lolin of pins 30, one ol which is mounted in each of the ball members 26. llath ol' `there` pins is formed with a cylindrical part 3l and a shoulder 32 and hw a nut 33 by means of which it may la adjusted and locked in its seat in the hall member. Also there is :in angular part 3l by which the piu may be turned. llaeh end of the pin is `formed with a crank or eccentric nib 13a to which the ends of the springs 27 are connor-.ted and it will he Seen that `by turning one of the pins in its seat 'these nibn may be moved relatively to the nibs of the other pin aud a tightening or lofaiening of the springs will result. 'lo
.thus adjust the tension -ol the Springs, it will he understood that it is only noessaljv to loosen 'the nuts 33, turn the pins the desired amount` and then tighten the nuts.
THD
A cap 36 is detachably secured to the casing 18 over the governor to thereby protect it from dfust and dirt while at the same time offering easy access for adjustment and reair.
p The lower part of the casing 18 is in the form of a cylinder 37, which is shown as having` its axis in line with the driving shaft 19 of the governor, and in this cylinder a hollow piston 38 operates and is springpressed upwardly as by the coil spring 39. The lower end of the cylinder 37 is closed by an adjustable cap 4() threaded into the cylinder and locked in adjusted position by a nut 41.
The piston 38 is formed with a stem 42 having a cross pin 43 which coperaties with the yoke ends 44 on the bell crank lever 17 hereinabove referred to. Thus, the tendency of the spring pressed piston 38 is to yieldingly press the horizontal arm of the bell crank lever 17 upwardly, and thus move the rod 1G to the right in Fig. 1 and close the throttle 12 in the intake pipe 10. Therefore, this springr device., as it may be termed, constantly tends to close the throttle valve 12, and it will be seen that the lower end of the operating rod 21 abuts the upper end of the stem 42 of the piston 38 and by reason of the greater strength of the springs 27 of the governor tendini;r to force the operating rod 21 downwardly, the valve 12, when the governor is idle, is held by the governor spring 27 in open position as shown in the drawings. Hence any adjustment of the tensionV of the spring 39 by the cap 40 will act directly on the governor. Therefore this arrangement provides a second and finer and more accessible adjustment for the governor.
lt will be understood also that as the overnor shaft 19 is rotated, the governor liall members 26 begin to move outwardly and thus raise the operatin rod 21. This permits the spring device-1n the cylinder 37 at the lower end of the governor casing l to aet upon the throttle valve through the connections shown and more or less close the valve, dependmg upon the exact position of the rod 21. Thus the piston 38 may be said to follow the operating rod 21 in upward movements, and if the Speed oi 1 governor shaft 19 were suddenly increased 'the ball members 26, would fly outwardly quickly and the throttle valve would be almost instantly closed. To prevent this sudden closing of the throttle under these conditions, a dash-pot mechanism is arranged'in combination with the piston 38. This dash-pot mechanism permits the piston to move downward rapidly but makes its upward movement more sluggish, Thus, the piston is provided with ports 45 and a valve 46 therefor slides on. the stem A light spring 47y presses the valve 46 down- Leemans wardly on the ports 45, but permits the valve to rise when the piston 258 moves downwardly. lt is intended that the cylinder 37 shall be filled with oil or a similar liquid to a point somewhat above the top of the piston 38 and the cylinder is provided with a by-pass -18 controlled by a valve` 45). which permits the slow passage of the oil around the piston. Thus it will be seen that when the operating rod 2l presses the piston 32 downwardly, the valve Vll-t will rise and .permit the oil beneath the piston to pass freely to the part of the cylinder above the pieton, and the movement ol' the rod 21. and consequently the opening action of the throttle 12, is not retarded in any way. However, when the operating rod 21 is suddenly raised as by a rapid increase in speed of the driving shaft 19, the piston will not readily follow the rod 2l, but will be sluggishin its movement due to the fact that the ports 45 will be closed by the valve 46 and the oil will by--pass slowly around the piston through the valved opening. Thus the throttle -valjte 12 will close more slowly than it would were there no retarding means provided, and therefore, while the governor and consequently the operating rod 21 may hunt `to some extent, the piston 38 and colisequently the throttle valve 12, will more slowly reach the normal running position of the parte where they will be controlled in the usual manner by the governor.
.lt will also be observed that by opening the hand controlled throttle 11 very suddenly, the motor may be speeded up and carried somewhat above its normal magimum speed before the governor-controlled throttle can suiliciently close to Check it. This will permit the operator to get a slight burst of power for starting the truck or getting it out of a hole, wherehe would not be able to do so if the throttle valve 12 immediately followed the position of the operating rod 21.
