.IOHN G. BAUMANN, OF MILWVAUKEE, \VISCONSIN.
SPEED-REGULATOR FOR SHAFTING.
SPECIFICATION forming part of Letters Patent No. 394,435, dated December 11, 1888.
Application filed August 13, 1888. $erial No. 282,610. (No model.)
To aZZ whom it may concern.-
Be it known that 1, JOHN G. BAUMANN, of Milwaukee, in the county of Milwaukee, and in the State of Visconsin, have invented certain new and useful Improvements in Speed- Regulators for Shafting; and I do hereby declare that the following is a full, clear, and exact description thereof.
M y invention relates to devices for regulating the speed of shafting; and it consists in certain peculiarities of construction, as will be set forth hereinafter, and pointed out in the claim.
In the drawings, Figure l is an end view, and Fig. 2 a side view, of my device applied to a line of shafting, portions of both figures being broken away or shown in section to better illustrate the construct-ion. 3 is a detail view of one of the adjustable weights.
A represents an ordinary shaft suspended by ordinary hangers and provided with a pulley-wheel, B.
C is a hub having a flanged plate, a, and squared boss b,through which th e shaft passes, and to which it is secured, as by a key or feather, 0, while on each side of the boss I), and at some little distance therefrom, are wings (I (l so as to leave, practically, a channel or depression all around the central square boss, I), on the flanged plate a, to receive a center plate, 6, (provided with central square perforations to fit around the boss I), and straight edges to fit against the inner edges of the wings (Z (1,) and from this center plate there project the flat arms D D, provided with rows of perforations f ff, the center plate, 6, being kept in place by means of another hub, E, and securing-bolts g g, passing through the hubs E C and center plate, 6, and provided with suitable nuts, as shown.
The ends of the described flat arms D D are provided with weights F F, which are of the general shape best shown in Fig. 3, so as to offer the least resistance in their revolution through the air,- and which may be adjusted nearer to or farther from the center plate, e, as desired, and secured in this adjustment by means of the retaining-strips G Gr, each having catches h [at one end to snugly fit against and retain the weight in place, and a perforation at the other end to register with any one of the perforations f of the arm D, and be secured thereto by means of the bolt is and nut, the outer ends of both the strip G and arm D passing through the central opening in the Weight F, and all being further held firmly together by a set-screw, 'm, as shown.
In practice I prefer to suspend a guard or cage around the path of motion of the weighted arms I) to prevent contact therewith, but have not deemed it necessary to show such in the drawings.
It will be readily seen that by my device I can regulate the speed of shafting, overcoming dead-centers and preventing diminution of speed at one time, or too great acceleration thereof at another time, and also can at will increase or diminish the throw or circumferential path of the weights, and hence adjust to a nicety the speed and power of the shafting, as may be desired from time to time.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
In a speed-regulator for shafting, the combination of suitable hubs secured to said shafting, a center plate held by said hubs, arms projecting therefrom, movable weights on said arms, and retaining-strips for adjusting and securing said weights at the desired distance from said center plate.
In testimony that I claim the foregoing I have hereunto set my hand, at Milwaukee, in the county of Milwaukee and State of Wisconsin, in the presence of two witnesses.
JOHN G. BAUMANN.
