Abstract:
A mouth actuated remote control unit operable to permit selective variation of a pneumatic operated controller having a proportional electrical control output to the electric motor of a sewing machine and wherein the controller has a fluid input port, said remote control unit comprising:a hollow, elastic, compressible bladder element for containing a quantity of controller actuating fluid and provided with a fluid outlet orifice;a fluid transmitting conduit connected to said orifice of the element and adapted to be operably coupled to the port of said control unit for conveying fluid from the element to the controller,said element being of length, width and height dimensions permitting insertion thereof in a persons mouth between the upper and lower teeth with the height dimension being such that when the element in uncompressed condition is positioned between the person's teeth, that person's upper and lower teeth engaging the element are held apart a distance no greater than an amount that can be comfortably accommodated,said element being formed of non-toxic, flexible material defining a hollow bladder element which is closed except for the outlet orifice thereof,said element being compressible by closing of the person's teeth thereon to effect transfer of fluid from the element through the conduit to the inlet port of the controller; anda one-way fluid valve associated with said bladder element and the conduit which is operable to prevent loss of fluid from the element and from the conduit when the element is compressed by the person closing their teeth, resulting in transfer of fluid from the element to the port of the controller, and allowing fluid to enter the bladder element and the conduit when the person opens their teeth, thus causing the elastic element to return to its original shape.
