GEORGE H. DIMOND, OF BRIDGEPORT, CONN, ASSIGNOR TO WHEELER 8:
IVILSON MANUFACTURING COMPANY, OF SAME PLACE. a
IMPROVEMENT IN BOBBlN-HOLDERS.
Specification forming part of Letters Patent No. 207,400, dated August 27, 1878; application filed April 29, 1878.
To all whom it may concern:
known that I, GEO. H. DIMOND, of
m Bri dgeport, county of Fairfield, State of Conside elevation, showing the bracket in upright position in full lines and turned back in dotted lines; Fig. 3, a front elevation; Fig. 4, a rear elevation, and Fig. 5 a section on lines ac a, Fig. 3.
The ordinary Wheeler & \Vilson machine has a device called a ring-slide, its purpose being to hold the bobbin within the hook, and such ring-slide is made adjustable toward and from the face of the hook. With such ringslide it becomes necessary to loosen the screw which confines the base of the ring-slide to the base of the machine each time the bobbin is to be inserted or removed, and when the bobbin is inserted and the slide is being secured in place by the screw the bobbin is liable to drop out of place. The rigid upright portion of this ring-slide has been made of different shapes to adapt it to the particular forms of machine to which it was to be applied-as, for instance, it has been made as a ring, and has also been made as a fiat piece of metal, provided with aspring.
This my improved bobbiaholder is applicable to all the different forms of Wheeler & lVilson machines.
The base a of the bobbin-holder is provided with. a rib or projection, o to enter a groove in the base I) of the frame c,with a stop-screw, d, to govern its position with reference to the book 0, and with a screw, (1 which works in a slot in the base a, to fix it in place, all as usual. I This basehaspivoted at one end, at f, a bracket, 9, provided, if desired, with a spring, h, to bear lightly against the bobbin w or bobbincover. At the junction of the base and bracket is placed a lockingdevice, composed, as shown in the drawings, of a spring, t, terminating in a hook, i, to engage a portion of the bracket and retain it in upright position, as shown in full lines, the bracket then holding the bobbin properly within the recess at the face of the hook. Upon this base is placed a disengaging device, 70, made in. this instance as a bolt, which, when pressed inward, releases the spring of the locking device from the bracketand permits it to be turned backward, as in dotted lines, for the insertion or removal of the bobbin.
The base of the bobbin-holder is made horizontally adjustable with reference to the face of the hook, in order to accommodate the bracket to bobbins of different thicknesses for different classes of work. It is obvious that this spring may have an opening to receive within it a pin or projection on the bracket, or vice versa.
I do not broadly claim holding a bobbin in position by means of a pivoted bracket; nor do I broadly claim such a bracket when it is engaged and held at its upper end by a spring, which does not form part of the removable bracket and base.
I claim The combination, in a bobbin-holder, of an adjustable or sliding base, a, the bracket 9 pivoted thereto, a spring-hook to engage the lower end of the bracket and to lock it to the base,
and a bolt, Ir, for disengaging the two, all to w I operate substantially as shown and described! In testimony whereof I have signed my nanie to this specification in the presence of two subscribing witnesses.
GEORGE H. DIMQND. Witnesses: I A. STEWARD, H. E. FRENCH.
