FLY-WHEEL.

SPECIFICATION forming part of Letters Patent No. 295,215, dated March 18, 1884.

(No model l T0 CIJ/ who/lt t may colli/Cerfa:

Beit known that I, Ruini-XV.' VnrrNnY, a citizen of the United States, residing at Cleveland, in. the county of Cuyahoga and State of Ohio, have invented cert-ain new and useful Improvements in Fly-Wheels, of which the iollowing is aspeciiication, reference beingh had therein tothe accompanying drawings, in which* Figure l is a vertical section of a iiy-wheel embodying my invention. Fig. 2 is a side elevation with the disk removed. Fig. 3 is a perspective of the disk and the binding-bolt. Fig. 4 is a perspective ci' the binding-bolt, and Fig. 5 is a modication.

' Like letters refer to like parts in all the iignres.

My invention relates to that class of ily` wheels which, or the adjuncts of which, are adapted to divert the power applied from the main machine` with which the flywheel is connected, to independentmechanism, Vwhereby the latter may be operated while the former is at rest, and although primarily and principally set forth herein as for use upon sewingmachines, my said invention is also fully and readily applicable to any mechanism which comprises independently operative parts, which it is desirable at will to use separately, and I therefore do not limit myself to an application of my said invention to sewing-machines, but reserve myl right to adapt the same for use upon any machine which permits of its use, or which, by the exercise of ordinary mechanical skill, can be Ina-de to permit its use. Taking a sewing-machine provided with a bobbin-winding,mechanism as an example of a machine which is adapted to receive and make use of my invention, it is well known that said bobbin-winding mechanismr is constructed to be thrown in contact with the belt which serves to convey motion fromthe treadle or crank shaft to the main shaft of the machine, and to be operated. In such cases it is apparent that the machine is also operated during the operation of the bobbin-winding mechanism, and itis the object of the class of ily-wheelsto which my invention relates to obvia-te the necessity of the simultaneous opera-tion of both mechanisms at such times.

Other objects and advantages of my invention will appear in the following description of its construction and operation, and the novel features of the same will he specifically set forth in the claims.

A represents the main shaft of a machine, and B a ily-wheel mounted thereon and secured rigidly thereto-in this instance by a setscrew, b, but any other well-known devices may be used instead of said set screw for the iirm' connection of the fly-wheel with the shaft. The hub of the fly-wheel is cut out to form a sleeve, B', and a rim or shoulder, B2, and although shown as interiorly and continuously fitting the shaft, the sleeve may not be so constructed, if desired. Any usual balance weight, C, may he secured to the wheel within the hub and between the sleeve and rim, but in this instance it 'performs an additional function, hereinafter described.

D represents a disk having a peripheral belt-groove, D, and is adapted to rotate upon the sleeve B of the hub. In this instance the disk is provided with a sleeve, D2, fitted to the sleeve B and extending 4within the hub. rlhe distance to which it shall extend is not essential, as all that is desirable is that the disk be mounted, directlyor indirectly, upon the shaft vA, and be capable of longitudinal movement upon the sleeve B', so that when held snugly against the rim or shoulder B2 of said disk the wheel and the shaft shall revolve as one piece..

The means or binding device employed in this instance for drawing and holding the disk in firm contact with the rini or shoulder Bicom prises a headed holt, E, and an interior circumferential groove, D, formed in the disk D, into which groove the head E ofthe bolt C IOO As thus far described, it is evident that the same operation could be attained were the groove D3 vmade eXteriorly and the bolt E relatively located; and so far as the particular lo cation of the grooveis concerned I do not limit myself.

To prevent the bolt from revolving in the groove, which would have atendency to loosen or run off the nut, I fiatten or cut away a portion of the head, so as to produce the surface e, (see Fig. 4;) but for this purpose the head may be pivoted upon the body, so as to rotate thereon7 or the body may be made square in cross-section; but these modifications increase the expense of manufacture and tend to increased friction and wear of the parts, andl hence I prefer the construction shown. In this instance, though ynot essential, I have shown the bolt passing through the weight C, and I,

thereby gain a longer bearing for the bolt, which is'advantageous, in that it renders the connection of the parts firmer and prevents accidental bending of the bolt, whereby the head thereof would be thrown out of line with the groove D3.

If desired, as shown in l, the hub of the wheel may be provided with a belt-groove, B3, in which case, in order to operate the disk independently of the wheel, the belt would be shifted from said groove into the groove D of the disk, and this change in the position of the belt may be useful, in that it might be the means of conveying power tothe bobbin-winder without shifting its position to bring it in contact with the belt, as would be the case were the beltrnn continuously in the groove ofthe disk.

Suitable oil-holes, D4D5, are shown for lubricating the sleeve and disk-groove.

I deem it proper to state that I do not wish to be understood as limiting myself to the eX- act proportion7 construction, and arrangement of the partshereinshown, but I may alter the same in any manner and to any extent within the skill of persons conversant in the construction of power-conveying mechanisms.

As before indicated,the disk may be mounted directly upon the shaft so long as it is capable of independent rotation thereon, and capable also of longitudinal movement toward and away from the hub of the wheel.

In using the terms circnmferentially grooved relative to the disk, I mean the groove D, whether located interiorly or eX- teriorly, and in unison or in company with the belt-groove; but for finished appearance I prefer the interior location of said groove.

Having described my invention and its operation, what I claim isi l. The combination of a fiy-wheelprovided with a rim or shoulder, a disk having a beltgroove, and an interior circumferential groove, with a binding device, substantially as specifled.

2. The combination of a ily-wheel having a sleeve and a rim or shoulder, a disk having a belt-groove, and a sleeve adapted to rotate and to move longitudinally upon the sleeve of the wheel, with a binding device, substantially as specified.

3. The combination of a belt-disk having a circumferential groove, and a binding device projecting into said groove and through the hub of a ily-wheel, substantially as specied.

4. The disk D, having the belt-groove D, the sleeve D2, and the groove D3, substantially 'as shown and described.

5. The combination of the disk D, having the belt-groove D and the groove D, with the bolt E, having the head E cut away, as at e, substantially as shown and described.

6. rlhecolnbination of the wheel B, provided with the rim or shoulder B2 and sleeve B', the disk D, having the groove D3, bolt E, having the head E, the weight C, and nut E2, substantially as shown and described.

7. rlhe combination of the wheel B, having the rim or shoulder Bgand sleeve B,'with the disk D, having the belt-groove D', sleeve D2, and groove D, and with the bolt E, having the head E', weight 0, and nut E2, substantially as speciiied.`

In testimony whereof I affix my signature in presence of two witnesses.
