BOBBlN-SPRING.
Specification of Letters Patent.
Patented .J uly 10, 1906.
Application filed March 4, 1904. Serial No. 196.494.
To all whom it may concern.-
Be it known that I, GEORGE M. BURGESS, a citizen of the United States, residing at Hopedale, in the county of WVorcester and State of Massachusetts, have invented a new and useful Bobbin- Spring, of which the following is a specification.
This invention relates to a construction comprising two intermeshing sets of springarms which has been especially designed for use as a bobbin-grip or as a means for connectinga bobbin to a spindle.
The especial object of this invention is to provide a bobbin-grip in which two sets of spring-arms are intermeshed, so as to secure equal pressure from a common center, and to provide a construction which may be readily and easily manufactured and which can be quickly assembled and put in place.
To these ends this invention consists of the construction and of the combinations of parts, as hereinafter described, and more particularly pointed out in the claims at the end of this specification.
In the accompanying drawings, Figure 1 is a side view, partly broken away, of a spindle having its whirl provided with spindle-gripping springs according to this invention.
ig. 2 is a perspective view of the upper set of s ring-arms. Fig. 3 is a perspective view of t e bobbin-supporting ferrule. Fig. 4 is a perspective view of the lower set of springarms. Fig. 5 is a side view of the whirl. Fig. 6 is a transverse sectional view of the lower set of spring-arms, and Fig. 7 is a side elevation of a whirl provided with the spindle-gri ping springs.
In United States Letters Patent No. 744,040, granted to me November 17, 1903, I have shown, described, and claimed a springpacking for spindle-bolsters, in which two sets of intermeshing spring-arms are employed for sup orting a spindle-bolster centrally within a ase.
The rimary object of this invention is to apply t e principles of construction shown in my prior patent to a bobbin-grip for a spindle; and a secondary object of this invention is to provide an improved way of confining the ends of the spring-arms and to im rove the details of the construction of suc springarms, whether they are employed either in a happensthat in crowding the bobbins ,down' into place with too much force the bobbins will be split or broken. In the use of a spindle provided with a bobbin-grip constructed according to this invention the spring-fingers will have sufficient outward tension to hold the bobbin rigidly in place, while at the same time the bobbin in all cases may be forced down against a fixed shoulder on the spindle, so that in the use of a spinning or twisting frame equipped according to this invention all bobbins will be at a fixed distance above the rail.
Referring to the accom anying drawings and in detail, as shown in I 4 ig. 1, A designates a spindle, and W designates the whirl thereof. The whirl W may be of substantially the ordinary or usual form, ,eXcept that the same is provided at its upper end with a shoulder 10, and the wheel of the Whirl is provided with an annular recess 11 for receiving the ring of the lower set of spring-arms. The face of the whirl is also preferably provided with two sets of four nicks or recesses, the upper set of said recesses 12 reoeivin the ends of the upwardly-extending set 0 springarms and the recesses 13 receiving the ends of the downwardly-extending set of springarms.
The upwardly-extending set of springarms 15 extend up from and are carried by a ring or bottom part 14. As shown most clearly in Fig. 6, the spring-arms 15 are preferably grooved longitudinally or curved upon a shorter radius than the ring 14, so that there will be no bearing at the edges of the spring-fingers which would prevent sharp edges or corners which would be liable to cut. Fitting down over the upwardly-extending set of spring-fingers is a supporting-ferrule which forms the support for the bottom of the bobbin. This ferrule, as herein illustrated, comprises a cylindrical body portion 16 of the flange 17. The body portion of the ferrule is provided with fourgrooves 18, which receive the upwardly-extending set of spring-arms 15. The downwardly-extending set of spring-arms 20 extend down from and are carried by a split ring 19. Y
In assembling the parts for a spindle as thu constructed the lower set of spring-arms is first forced down into place, so that the bot tom ring sets into an annular groove 11. The supporting-ferrule is next forced down into place over the first set of spring-arms, the spring-arms extending up through the grooves 18 of the ferrule. The top set of spring-arms of intermeshing spring-arms may be bowed onto the spindle, while at the same time the outwardly at different points in their length,
so as to furnish two separated places of engagement.
In the use of a bobbin-spring as thus constructed a bobbin may be held in place with s'uflicient firmness so that it will be locked bobbin will not be cracked or broken by being ut onto the spindle, and it may always be orced down into engagement with the fixled collar or flange of the supporting-ferru e.
Certain features of the construction herein shown and described are also applicable to the construction of a spring-packing for a s indle-bolster. For example, I have found t at the longitudinally grooving or curving of the spring-fingers upon a shorter radius than the radius of their supporting-ring to prevent engagement with sharp edges and also the confining of the ends of the springfingers in notches or nicks are features which can be used to advantage in the spring packings or bolsters. I do not wish, therefore, to
be limited to the special construction I have herein shown and described, nor to this special application of my invention but What I do claim, and desireto secure by Letters Patent of the United States, is
1. The combination of aspindle, and means for securing a bobbin thereto comprising a base-piece, spring-arms extending up therefrom and a top piece having spring-arms extending down therefrom and intermeshed with the first set ofspring-arms.
2. The combination of a spindle, a whirl ,mounted thereon, an upwardly-extending set of spring-arms carried by a connecting piece or ring, which is fitted into an annular recess in the whirl, a second set of springarms extending down from a connecting piece or ring, and intermeshed with the first set of spring-arms, and a supporting-ferrule having a body portion which is slotted longitudinally to receive the first set of springarms and having its top surface or flange forming a fixed shoulder for engagement with the bottom of a bobbin.
3. In a construction of the class described, for use as a bobbin-grip, spring-packing, or for similar purposes, the combination of a cylindrical part, a set of spring-arms extending from a connecting piece or ring, a second set of spring-arms extending from a second connecting piece or ring and intermeshed with the first set ofspring-arms, the ends of one set of spring-arms being tucked into place behind the connecting piece or ring of the other set of spring-arms and fitting into notches or sockets in the cylindrical part.
4. In the construction of the class described, the combination of two connecting pieces or rings, spring-arms extending from one connecting piece or ring and a second set of spring-arms extending from the second connecting piece or ring and intermeshed with the first set of spring-arms the cross-section of each of said spring-arms being of curved shape on a radii shorter than the radius of the connecting-pieces.
In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
, GEORGE M. BURGESS.
