ed with the valve-stem and by meansof which. the resistance of the valve to the action of the governor could be varied; but these devices,
were capable of providin for but a'small variation of the normal engine speed, and modern practice requires a much wider range. It is to meet this demand that my invention has been produced.
governor-head.
elevation of a governor embodying my inven tion with some parts broken away .and others shown in section for purposes of illustration. Fig. Zis a detail view showing my'mjethod of spective view of the upper part of the spindle I Fig. 4 is a view of the end face of the adjusting-rod, showing the engaging points. Fig. 5 is a perspective view of the coupling Fig. 6 is a sectional view of the same.
Referring to the drawings, arepresents the 3 shell of the valve, 1) the valve proper,'and c the valve-stem. To the shell of the valve .is
secured the frame d, providedwiththe spindle e, on which the governor is rotatably mounted. The governorillustrated is of the type having upper and lower sleeves f f fitting on the spindle and provided with flanges f f towhich the ends of the'ball-carrying- I springs are secured. The top flange f has a threaded boss f to receive a bonnet-nut, as later described.
in any suitable manner to a coupling-piece g. Passing down through the spindle e is anadjusting-rod h, which is threaded to engage against rotation.
The usual method of doing this was wise with respect thereto, but holding it The adjusting-rod has an operating-handle, as the knurled head it.
Its lower end fits into a recess in the coupling x g, and the face of this lowerend is provided with engaging points 7%, which cooperate with similar points at the base ofthe socket or on the part with which the adjusting-rod contacts in order toprevent the accidental turning of this adjusting-rod. These engaging points are not deep enough, however, to prevent the ready turning of the rod by the knurled head it". w
A bonnet-nut incloses the sleeve-nut '1',
and is screwed to the threaded boss f This centrifugal. action of the weights the sleeve- I nut and the adjusting-rod will be carried with 7 5 Another object of my invention relates to I the manner of mounting the springs i'nthe' it, this downward movement being transferred to the valve-stem through the coupling g to cause a corresponding movement of the In the drawings, Figure 1 is a perspective? valve. A thin metallic washer is is interposed between these shoulders in order to al- 86 the coupling 9. Means are provided, as the worm-gear m, for winding up this spring,
causing the dog to exert an upwardpressure 9o on the coupling. This spring tends to lift the valve, and its force must be Overcome by the governor in order to close the valve.
.The operation of the device is as follows, it
being understood that the governor is driven 5 from the main shaft of the engine through the pulley 0 and the beveled gears 11: .The valve is set to meet'ordinary conditionsof'use by winding up the torsional spring m until it exerts an upward pressure on the valve-stem, Ioo ..'which will be counterbalanced by the centrifugal force of the rotating governor-head I use a short valve-stem c, which is secured unusual causes the speed of the engine is to To 5 beincreased or it is desired to increase the threads in a sleeve-nut 'i, which is splined to v the spindle'e, leaving it free to move length- 55 carries a dog a, which engages shoulders on speed of the engine during certain hours of the day, the adjusting-rod is unscrewed from the sleeve-nut i, permitting the valve to be raised under the influence of the spring, giving it a greater distance to travel in controlling the admission of steam. In consequence the engine speed must increase. The speed of the engine is diminished by screwing down the adjusting-rod and closing the valve independently of the governor action. noted that all parts of this adjusting device It is to be are non-rotatable and in consequence that it cannot be affected in any way by the rotation to the top and base flanges of the governor- These flanges f f have slots 25 milled in them, the bottoms of which are at angles to their axes. The springs u u at each end are secured firmly in these slots flat against the bottoms, with the result that when the governor is at rest the springs are on an even continuous curve from the top to the bottom flange. When the governor is in action, the springs of course are curved still more; but under ordinary conditions the curve is substantially a continuous even one from flange to flange, resulting in a more continuously uniform action of the governor-head. In assembling these parts the springs are secured in place in the grooves, the bands 1) are shrunk onto the flanges, and the space over each spring is filled by pouring in a molten metal, as lead, (seen at w.) Thus when the whole structure is assembled the parts are solidly bound together and an advantageous construction is provided.
I claim as my invention -1. A governor for steam-engines and the like comprising the valve-chamber, the valve and its stem, the governor-head, and means for adjusting the valve vertically independently of the governor-head comprising a non rotary nut and an adjusting-rod threaded into said nut with its end connected with the end of the valve-stem, and connections between the top flange of the governor-head and said adjusting-rod to cause them to move together vertically, as and for the purposes specified.
2. A governor for steam-engines and the like comprising the valve-chamber, the valve and its stem, yielding means normally exerting an upward pressure on said valve, the governor-head, and means for adjusting the valve vertically independently of the governor-head comprising a non-rotary nut and an adjusting-rod threaded. into said nut with its end connected with the end of the valvestem, and connections between the top flange of the governor-head and said adjusting-rod to cause them to move together vertically, as and for the purposes specified.
3. A governor for steam-engines and the like comprising the valve-chamber, the valve and its stem, yielding means normally exerting an upward pressure on said valve, the governor-head, and means for adjusting the valve vertically independently of the governor-head comprising a non-rotary nut, an adjusting-rod threaded into said nut with its end conected with the end of said valve-stem, and a bonnet-nut secured to the top flange of the governor-head and having engagement with said nut whereby said nut takes its vertical movement from the vertical movement of said governor-cap.
4. A governor for steam-engines and. the like comprising the valve-chamber, the valve and its stem, yielding means normally exerting an upward pressure on said valve, the governor-head, and means for adjusting the valve vertically independently of the governor-head comprising a nut splined to a nonrotary part of the governor and adapted for lengthwise movement thereof, an adjustingrod threaded into said nut with its end connected with said valvestem, and connections between said nut and the top flange of the governor-head to cause them to travel together vertically.
5. In a governor the cap and base-rings, and two or more springs secured thereto, the plane of attachment of said spring to said rings being angularly disposed with reference to the axes of the governor.
6. In a governor the cap and its rings having peri heral slots the bottoms of which are angular y disposed with relation to the axes of the governor, and springs having their ends firmly secured to the bottoms of said slots, and weights attached to said springs.
7. A governor for steam-engines and the like comprising a valve-chamber, a valve and its stem, a governor-head, and means for adjusting the valve vertically independently of the governor-head comprising an adjustingrod threaded. in a non-rotary part with its end connected with the end of said valvestem, and engaging points on the end of said adjusting-rod.
In testimony whereof I aflix my signature in presence of two witnesses.
