G'YBATGBY MACHINE.
Ipeaimtion of Letten Patent.
Application led october 30.
Patented Mor. 22, 1910. isos. serial No. 460,205.
To all whom it may concern:
Be it known that I, Joins Fransen: a citizen ofthe United States, residing at Milwaukee, g in the county of Milwaukee and State of i Wisconsin, have invented certain new and useful Improvements in Gyratory' Machines, of which the following is a specification, reference being had to the accompanying drawing, forming a part thereof.
This invention relates more particularly to freely suspended or supported gyratory in achines of the class shown and described in application Ser. No. 322,149 filed June 18, 1906.
The main objects of the present invention are tcmore evenly balance a machine of this kind when it is at rest around the central weighted shaft or axis, so that in starting and stopping its gyratoi'y orbit will increase and diminish more gradually u s the speed of said shaft increases and diminishes; to provide for shiftin centrifu al weights of greater mass, ang a. more e ective and advantageous arrangement of springs and guides; and generally to improve the construction and operation of the means for producing and determining the gyratory movement of machines of this class.
It consists in certain novel features of construction and in the peculiar arrangement and combination of parts as hereinafter particularly described and pointed out in the claims.
In the accom anying drawing like characters designate t e same parts :in both figures.
Figure 1 is a central vertical section of a gyratory bolting machine enibodyin the present invention, the sieves being omitted; and Fig. 2 is an enlarged plan View of one of the shifting weights with its connections and associated parte for varying and regulating the ratory movement of the machine in stopping and starting.
Referring to Fig. 1, c designates the caso l or frame-of the halting machine, which is freely suspended by jointed or flexible hangers l;2 from a ceiling or overhead support o, 1 and 1s provided at or near the center with bearings d for a vertical rotary shaft e. This s aft is provided with a pulley f which 5 is connected y a belt. g runnin on guide pulleys h attached to the case or rame, with a suitably located driving pulley, not shown. 1'
On the shaft e above and below the case a cross heads formed centrally on one side with hubs 7' which are secured on said shaft by set bolts or other suitable means.
Radially movable shifting weights Z are mounted on parallel guide rods m, which are secured nt their inner ends in the cross heads 2'. These rods are connected and held in the proper relation to each other at their outer ends by cross pieces n. The middle rod of each roup projecting radially from the hub j cig the associated cross head z', is located above or below the plane of the outer rods, and thus forms therewith and with the connecting cross piece u, u still' self-bracing supporting and guiding structure for the shifting weight mounted thereon.
Two parallel rods o, passing loosely through euch cross head if on opposite sides of the shaft c, are secured at one end in the associated weight l, und ut their opposite ends are connected by a plate or oke i. Spiral compression springs f2 cucire ing t e rods o between the cross head z' and the plate p, tend to draw and hold the weight l against the cross head z'. A third rod r is preferably secured at one end in the cross head t midway between and parallel with the rods o, and passes loosely through an opening in the plate or yoke p, which serves as a guide therefor, and a spring ff surrounding this rod between said cross head and plate cooperates with the other springs to draw the weight l toward the shaft c und to afford a veldin g resistance to the outward movement of said weight by' centrifugal force when the shaft c is rotate The plate p is udjustablv secured on the rods o by nuts, and affords means for adjusting thc tension of the springs q. l
The outer guide rods m are adjustable collars s secured t screws t and serving as stops provided with iereou by .set for limiting ,the outward nioveuient of the weights l.
The weights l are preforuhlr' cut away or recessed us shown. so that when they ure thrown to the outer limit of their movement they will extend over the collars x.
'lho cross heads e' are preferably counterhored to form sockets for the springs around thc rods o and r, so us lo admit ci shortening said rods iu connection with springs of :l given length.
The weights l, which are heavier than thc cross heads 1i, aro cut away on their inner 55 are mounted parallel with euch other, two I .sides hotwoon the rods n. as shown in Fig. '2,
llt
y :to ,tit over 4the habe-5j of the associated creas 4houle a', that when the nnuizhine is arrest und said weights are held bythe spain s y iu their inner positions, the machine wi4 be apprrmiuately iu balance around the axis of the Shaft e, the cross heads i' acting ascoiin terweights with respect to the shifting weights l.
The machine operates as follows: .In starting, the shifting weights l being held by the springs g at the linut of their inward movement close to the cross heads or counter wei hts '5, the axis of the shaft c will at first be 'xed or describe a very small gyratory circuit, but as the speed of the shaft increases, thc .weights l will be gradually Inoved away from it. by increasing centrifugal force against t-he resistance of the springs y; the center of gravity being thus gradually shifted away from the axis of the shaft e, the latter with the freely suspended case Vor frame in which it turns, will be caused to gyrate in a gradually enlarging circuit about an axis coinciding wit-b or assing through the center of gravity. iJVhen the shaft e attains its full normal speed, the outward movement of the Weights l is arrested by the adjustable collars or sto is s, and the or frame a., with its loaf, gyrates about its center of gravity, which is determined or modified by the posi tion of said Weights relative to the axis of said shaft. The center of gravity ot' the machine being thus gradually shifted away from the axis of the shaft e, and the gyratory orbit or circuit increasing gradually from zero to its full or normal limit, the center of gravity or normal axis of ration will never cross the path of gyratlon, and the erratic movements and consequentshock and jar to the machine and its supporting connections, which would occur if the weights were permanently adjusted to produce the normal gyratory circuit, are avoided.
In stopping, as the rotary speed ofthe shaft e and the centrifu al force acting on the wei bts l are reduced, the weights l are gradua y moved inwardly toward said shaft, the center of gravity of the machine gradually approaches the axis of the shaft and the Uyratory orbit or circuit described hy said s aft gradually diminishes until it finally comes to rest when the weights rc sinne tli'cir initial positions, and the axis of gvrntion or the center of gravity of thc nur c line coincides with the axis of said shaft. 'lhus in stopping as in starting, erratic movements and consequent shock or jar to the machine are avoided, and a cushion. guide or other means for confining the niovement of the machine within certain limits, is dispensed with.
i Various changes in the details of construetionnnrl arrangement of parts may be made i "reageer without departing from the principle and swipe ort the invention.
