Specification of Letters Patent.
Patented May 21, 1907.
Application filed December 26, 1906. Serial No. 349,467.
The object of my invention is to Aprovide an improved construction of governor for regulating the speed of engines or motors in general, and the invention consists of an improved construction of air cylinder which is adapted to impose a certain amount of work upon the engine by pumping air into the cylinder, the said cylinder being vented at varyn ing predetermined pressures, all as will be hereinafter fully described and claimed.
For a full understanding of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result, reference is to be had to the following description and accompanying drawings, in which: Figure 1 is a side elevation of my improved governor cylinder, parts being broken away to show the interior mechanism, Fig. 2 is a similar view illustrating a modification here- 'inafter specifically referred to.
Referring to the drawing, the numeral 1 designates the cylinder provided at each end with heads 2 that are preferably bolted there- 3 designates an air inlet pipe which leads from the pump (not shown) that is intended to be driven by the engine for which my improved cylinder constitutes the governor.
4 designates a gage pipe which is secured to the cylinder and which is provided with a T-shaped end 5 of which one arm carries the gage 6 and which the other arm carries a vane-capped whistle 7. 7 a designates a valve in such arm of the T-shaped end of the pipe 4, so that the air to the whistle may be con trolled Aor shut oi'l, as desired.
Within the cylinder 1 are two oppositely acting pistons 8 and 9, the rods 10 and 11 of which extend respectively out through pref erably stuffed openings in the heads 2 of the cylinder. A cross-bar 12 is secured to the outer end of each of the rods 10 and 11, and sets of coiled springs 13 are secured to the ends of these cross bars and also secured at their'inner ends to the cylinder or to the head in any desired manner. These springs exert tension to draw the piston rods into the cylnder and move'the two pistons 8 and 9 to ward each other and toward the middle of the cylinder.
The cylinder is provided with vent cocks 14 which, in the present instance and in the embodiment illustrated in 1 are shown' as arranged in two series, five in each series. The cocks of one series are designated A, B, C, D, and E, and the others, A, B, C', D/ and E. Each one of these vent cocks is provided with a valve intended to be turned by hand to open and close the cock.
In the practical operation of my improved cylinder governor, the load imposed upon the `engine to which the cylinder is applied so as to govern the speed thereof may be regulated by means of the various cocks. For instance, if it be desired that the engine run under a very light load, the vent cocks A, A are open, as the engine operates, it pumps air into the cylinder and consequently will move the two pistons 8 and 9 apart andy outwardly away from each other, against the action of the coiled springs 13, but as soon as the pistons shall have passed the vent cocks A, A it .is manifest that the air will vent itself and the engine will not be called upon to work up to any higher pressure. The varying pressures desired may be readily determined by means of the gage 6, as is evident. Again, if desired, the cocks A, A', B, B', C, C and D, D may all be closed and the cocks E, E opened. Under these conditions, it is manifest that a much higher pressure of air will be reached within the cylinder and the engine will have to pump air into the cylinder until the pressure is sufficient tomove the away from each other a distance to or beyond the outermost vent cocks E, E. As the air is vented, it is obvious that the coiled springs will exert their tension to move the pistons 8 and 9 toward each other, and it is to be understood that the tension of these springs is resisted at all times by the pressure of air between the pistons. By this means the speed of the engine may be regulated and the pistons caused to be held by the air pressure at about the planes of the respective vent cocks, according as these different cocks are opened, or closed.
ln the modification illustrated in Fig. 6, I use one piston instead of two. ln this modified form 1a designates the cylinder which is preferably arranged upright, 2EL the head thereof, 3a the air inlet pipe, 45L the gage pipe, 8at the piston, 10a, the-piston rod, 12, the cross bar secured to said rod, and 13a the pistons 8 and 9 IOO IIO
springs adapted to move said piston rod and piston inwardly or downwardly within the cylinder. laa designates the series of cocks. In this construction, the parts work in a similar manner to the parts embodied in the construction illustrated in Fig. l, except that only one piston is used instead of two.
Having thus described the invention, what is claimed as new is.
1. In a governor, the combination of an air cylinder provided with an air inlet, and a series of vent cocks, means for opening and closing the respective cocks, a piston mounted to move within the cylinder by the pressure of air therein, a rod secured to said piston, and means secured to said rod for resisting the pressure of air exerted on said piston.
2. In a governor, the combination of an air cylinder provided with an air inlet, and a series of vent cocks, the series extending longitudinally of the cylinder, means'for opening and closing the respective cocks, a piston mounted to move in said cylinder by the pressure of air therein, a rod secured to said piston and extending out through the head of the cylinder, a cross bar secured to said rod, and contractile springs secured to said cross bar and to the cylinder and adapted to resist the outward movement of the piston.
3. A governor of the character described, comprising an air cylinder provided with an air inlet and an air pressure gage and also provided with a longitudinally extending series of vent 'cocks, means for opening and closing the respective cocks, a piston mounted in said cylinder and movable by the pressure of air therein, a piston rod secured to said piston and extending out through the head of the cylinder, a cross bar connected to said rod, and contractile springs secured to said cross bar and said cylinder and adapted to resist the movement of the piston as it is: acted upon by the air pressure. z
In testimony whereof I aiiix my signature in presence of two witnesses. L
