GOVERNOR.
APPLIOATION FILED NOT-9, 1908.
Patented Nov. 12, 1912,.
DIXON IE. WASHINGTON, OF CHICAGO, ILLINOIS, ASSIGNOR OF ONE-HALF TO CHARLES W. PATTON, or CHICAGO, ILLINOIS.
GOVERNOR.
To all whom it may concern:
Be it known that I, DIXON E. WASHING- TON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Governors, of which the following is a specification.
This invention relates to improvements in governors particularly adapted for use in engines and the like, and the primary object of the same is to provide an improved device of this character in which the governor weights are adapted to move independently of their supports and in which the inertia of the weights will cause an adjustment of the governor.
A further object is to provide improved means for holding the weights in position with respect to their supports and improved means whereby the position of the weights with respect to their supports may be varied.
A further object is to provide improved means for yieldingly holding the weights in position and improved means whereby the tension of the said holding means may be varied.
A further object is to provide an improved device of this character which will be simple, durable and cheap in construction, and elfective, efiicient and positive in operation.
To the attainment of these ends and the accomplishment of other new and useful objects, as will appear, the invention consists in the features of novelty in the construction, combination and arrangement of the several parts hereinafter more fully described and claimed and shown in the accompanying drawing illustrating the embodiment of the invention, and in which Figure 1 is an elevation, partly in section, of an improved device of this character in accordance with the principles of this invention. Fig. 2 is an enlarged detail sectional view on line 22 of Fig. 1. Fig. 3 is an enlarged detail sectional view on line 3-3 of Fig. 1. Fig. 4 is an enlarged detail sectional view on line 44 of Fig. 1.
Referring more particularly to the drawing and in the present exemplification of the invention the numeral 10 designates the usual rotatable support for the governor arms, to which is secured adjacent the upper end thereof the cross head 11. The arms or upper links 12 of the governor are pivotally Specification of Letters Patent.
Application filed November 9, 1908.
' PatentedNov.12,1912. Serial No. 461,668.
connected by one extremity to the cross head 11 in the ordinary and usual manner.
The weights 13 may be of any desired configuration but are preferably of the ball type having an extended neck or portion 14 projecting from the weights and each of the Weights is provided ing into its body portion and opening through the neck or extended portion 14. The opposite walls of the recess adjacent the extremity of the neck or portion 14 are preferably beveled as at 16, for a purpose to be set forth.
The free extremity 17 of each of the arms or upper links 12 is preferably tapered as shown more clearly in Fig. 3 of the drawings, and these extremities project into the respective recesses 15 of the weights 13. Each weight is pivotally connected to its arm or link 12 in any desired or suitable manner, preferably by means of a sectional pin, one section 18 thereof being provided with a reduced extremity 19 and the other section 20 with a recess 21 to receive the reduced extremity 19. These sections are passed respectively through opposite walls of the recess 15 of the weight 13 so that the heads of the respective sections will rest against the outer face of the walls of the recess.- A portion of the arm 12 through which the pivot pin passes is preferably enlarged as at 22 for reinforcing or strengthening the arm at this point.
Pivotally connected to each of the weights 13, preferably the neck or extended portion 14 at points adjacent the point of pivotal connection of the weight with the arm 12 is a yoke 23, the arms 24 of which engage the sides of the neck or portion 14. The arms are pivotally secured in position by means of pivot pins 25 which pass through the arms of the yoke and into the neck, or portion 14 of the weight. If desired, the free extremity of each of the pivot pins 25 may be reduced as shown and screw-threaded for the reception of nuts 26 which hold the yoke against displacement. The yoke 23 is secured to the weight 13 on pivots arranged transversely to the pivot which connects the weights with the arms and supported by the yoke is a sleeve or tubular portion 27, which is provided with internal screw threads 28.
The lower links 29 of the governor are pivotally connected by one extremity to a with a recess 15 extendcollar which is secured to the slidable member 31 of the governor in the ordinary and usual manner. The free extremity of each of the links 29 is screw-threaded as at 32 and is adapted to enter and engage the screw thread 28 in the respective sleeve or tubular portion 27 on the yoke 23 so that when the yoke is axially rotated, the engaging screw-threaded portions of the sleeve 27 and the extremity of the link 29 will cause the said extremity to be moved into or out of the sleeve or tubular portion 27 to shorten or lengthen the link 29.
Any suitable means may be provided for holding the weight 13 in position with respect to the supporting arm 12 and for this purpose there may be provided suitable elastic members 33 in the form of coil springs or the like, two of which are preferably employed, one on each side of the arm 12 and with one extremity respectively engaging opposite faces of the extremity of the arm and the other extremities respectively engaging adjustable members 34 in the form of nuts having screw-threaded peripheries which engage suitable screw threads 35 in the apertures 36 arranged at diametrically opposite points in the weight and which communicate with the recess 15 so that a portion of each of the elastic members 33 will project into the recesses 36 to engage the respective nuts 34. If desired, these nuts 34 may be provided with key seats 37 by means of which the nuts may be adjusted to vary the tension of the elastic members 33. hen the nuts 33 are adjusted so that the tension of the elastic members 33 will be uniform, the extremity 17 of the arm 12 will be in a position to permit the weight 13 to' move the same distance in either direction.
With this improved construction, it will be apparent that when the governor is rotated in the ordinary and well known manner, the weight 13 will be thrown outwardly by centrifugal force which will adjust the member 31 on the member 10 in the ordinary and well known manner, but as the weights 13 are capable of an independent movement with respect to the arms or upper links 12, the inertia of the weights will impart an axial rotation to the sleeve 27 to lengthen or shorten the link 29 according to the speed of the governor. By thus lengthening or shortening the link, the governor will be automatically adjusted to cause the same to operate quickly upon the member to be shifted. With this improved construction it will also be apparent that the inertia of the weights will compensate the load fluctuations without changing the horizontal plane of operation of the governor weights, thereby producing a compact arrangement whereby the operation or shifting of the member to which the governor is connected will not rely solely upon the centrifugal force generated by the governor to throw the weights into a higher horizontal plane. By the provision of the inclined portions 16 of the walls ofthe recess, the weights will be permitted to move freely about their pivots without coming in contact with the extremity of the arm 12.
The recess 15 within the weights may be of any desired size, but it is preferable to provide a recess which is of a width only slightly greater than the width of the ex tremity of the arm, and the lower portion of the recess in which the extremity 17 moves is preferably enlarged, as shown, to permit a free movement of the weight with respect to the arm.
