Cone spool mounting adapter for a sewing machine

Abstract

An adapter for mounting a cone spool on the spool pin of a regular home type sewing machine. The adapter has a truncated conical upper end portion that inserts into the lower open end of a cone type spool. There is an aperture in the body that slip fits onto the vertical pin on the sewing machine and a second aperture offset from the axis of the adapter to slip fit onto a horizontal spool pin of sewing machines so equipped. A slender rod like member is mounted on and projects upwardly from the adapter and terminates in an eyelet to guide the thread as it leaves the spool.

We claim:  
     
         1 . An adapter for mounting a cone spool on a regular home type sewing machine having a pin for a conventional small spool of thread, said adapter comprising: 
 a body member having an upper end portion for inserting into a cone spool having an open bottom;    a body member including a vertical aperture for cooperatively engaging a pin on said sewing machine for supporting said cone spool in a vertical orientation on the sewing machine; and    a thread guide mounting on said body member.    
     
     
         2 . The adapter of  claim 1 , wherein said thread guide comprises a slender elongated member projecting from said body member and terminating in an end located beyond said upper end portion of said cone spool mounting on said adapter, said terminal end portion having an eyelet thereon through which the thread passes as it leaves said spool cone.  
     
     
         3 . The adapter of  claim 2 , wherein said eyelet is disposed above the center of said cone spool.  
     
     
         4 . An adapter as defined in  claim 1  wherein said upper body end portion is tapered for cooperatively engaging a cone spool having a tapered open bottom.  
     
     
         5 . The adapter of  claim 1 , said body including an aperture formed therein along a longitudinal axis disposed transverse to and laterally offset from the axis of said cone spool mounted on said adapter.  
     
     
         6 . The adapter of  claim 1  wherein said body end portion is a truncated conical portion.  
     
     
         7 . The adapter of  claim 1 , including a pin mounting on a top surface of said body.  
     
     
         8 . An adapter comprising an elongate body member having a lower portion and an upper truncated conical portion, said truncated conical portion being sized to mate with an open bottom end of a cone spool to support the same, an aperture in the lower portion of said body that slip fits onto a spool pin on a standard sewing machine and support the cone spool on the adapter in a vertical orientation on said machine and a thread guide comprising a slender member anchored at one end thereof to said lower portion of said body member and terminating in an opposite free outer end and means adjacent said free outer end to guide thread on said cone spool as it leaves the spool, said thread guide being located above an upper end of a cone spool mounted on the adapter.
