UNITED ST T S PArroFFic GEORGE E. MAGRATE, OF W HITINSVILLE, MASSACHUSETTS.
BOBBIE CLUTCH.
Application flied July 28,
novel clutch device to be mounted upon a,
s indle for the pn ose of gripping and h dlding thereon a s p ool or bobbin such as iscommonly used.
An important object is the provision of a clutch of this character which employs spring pressed convex members which will operate to ip within the hole in the bobbin.
11 additional object is the provision of a device of this character which will be simple and inexpensive in manufacture and installation, eficient in use, labor saving, durable and a general improvement in the art.
With the above and other objects and advantages in view the invention consists in the details of construction to be hereinafter more fully described and claimed and illustrated in the accompanying drawings, in which:
Figure 1 is a side elevation of my improved bobbin clutch,
Figure 2 is a longitudinal section and Figure 3 is a view of the blank from which the spring members are formed.
Referring more particularly to the drawings the letter A designates a spindle such as is used in many machines in the textile art, this spindle being tapered as is customary and carrying a drive pulley B.
In carrying out my invention I provide an elongated cylindrical casing member or body 17 which has one end formed with a hole of such size that it may be jammed onto the spindle. This body is formed with a plurality of holes 18 arranged in series as shown. Secured within the member 17 is a spring device which is formed from a single blank 19 of spring metal cut to define a plurality of tongues 20 terminating in circular portions 21. This blank after being cut is bent into circular form and the circular end portions 21 are cupped to an outwardly convex form. This spring member is disposed within the tubular member 17 in such position that the portions 21 will 1922. Serial no; mass.
project through the holes 18, and is riveted in lace.
rom the foregoing description and a study of the drawings it will be apparent that I have thus provided a simply constructed and consequently inexpensive clutch device for holding bobbins upon spindles in a very efiicient manner and in such a way as to prevent tanglin of the threads with the mechanism. Owing tothe simplicity of the construction and the fewness of the parts.
it is apparent that there is nothing to get out of order so that the device should have a long life and satisfactorily perform all of the functions for which it is intended.
While I have shown and described the preferred embodiment of the invention it is of course to be understood that I reserve the right to make such changes in the form, construction and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claims. Having thus described my invention I claim:
1. A bobbin clutch for a spindle comprismg a casing mounted on the spindle and having openings therein, and a plurality of spring fingers mounted in fixed position within said casing and having outwardly displaced portions of their free ends projecting outwardly through said openings to engage and hold a bobbin on said spindle.
2. A bobbin clutch for a spindle comprising a casing mounted on the spindle and having openings therein, and a plurality of elongated spring fingers within said casing, each having the free end portion thereof convex in cross section with its outer face projecting through one of said openings and effective to engage and hold a bobbin mounted on said spindle.
3. A bobbin clutch for a spindle comprising a casing mounted on the spindle and having openings therein, and a driving member supported within said casing and having a plurality of spring fingers each formed at its free end portion with an outwardly curvedface projecting through one of said openings and effective to enga e and hold a bobbin mounted on said spind e.
4. A bobbin clutch for a spindle comprising a casing mounted on the spindle and having openings therein, and a driving member formed from a single piece of resilient sheet metal and having a substantially cylindrical body portion and a rality of inte al upwardly exten ing spring fingers ormed thereon, said body portion being fixed in position relative to said casing and the upper free end portions of said fingers being outwardly displaced and projecting outwardly through said openings and efi'ective to engage and hold a bobbin mounted on said spind e.
5. A bobbin clutch for a spindle comprising a casing mounted on the spindle and having openings the-rein, and a driving member formed from a single piece of resilient sheet metal and having a substantially cylindrical body portion fixed to the inside of said casing and a plurality of integral upwardly extending spring fingers formed theeron, the upper free end rtions of said fingers being outwardly displaced and projecting outwardly through said 20 openings and effective to enga e and hold a bobbin mounted on said spind e.
In testimony whereof I afiix my si nature. GEORGE H. MAGR TH. 1
