Definitions
- Our invent-ion refers to intermediate gearlng more especially for use with sewing machines and the like. It is an ob ect of our invention to provide agearing which allows tightening quickly and easily the belts connecting the shafting as well as the sewing machine with the intermediate gearing without being com elled to shorten the belts or
- the novel intermediate gearing further has the property of bringing about a transmission of power from the shafting to the sewing machine which is at unnecessary. However, this the same time elastic and free of shocks.
- Fig. 1 is a front elevation and Fig. 2 is aside elevation of an intermediate gearing embodying our invention, the gearing being shown applied to the underside of a sewing machine table.
- Fig. 3 is a cross section on the line III-III in Fig. 1.
- Fig. 4c is a diagram showing the transmission of power from the shafting to the sewin machine.
- 14 is the sewing machine table
- 1 is a bed plate fixed to the underside of this table
- 2 is the frame supporting the stationary spindle 3 for the pulleys 15 of the intermediate gearing.
- the frame 2 can be fixed in horizontal as well as in vertical position. It is mounted for rocking motion on eccentric discs 4 keyed onto a spindle 5.
- a leafspring 6 fixed to the bed ed hole 16 in the frame 2.
- Intermediate gearing for sewing machines comprising a support, a spindle mounted in said support, an eccentric on said spindle, a frame pivotally mounted on said eccentric, an intermediate shaft mounted on said frame, a belt driven pulley carried by said shaft, a belt driving pulley carried by said shaft, means whereby said frame may be adjusted on said eccentric for'tightening the belt on the driven pulley, and means for turning said spindle for bodily shifting said frame for tightening the belt on said driving pulley.
- Intermediate gearing for sewing machines comprising a support, an intermediate shaft, a frame pivotally mounted on said support and carrying said intermediate shaft, a belt driven pulley on said intermediate shaft, a. belt driving pulley on said intermediate shaft, spring means acting to maintain a constant tension on the belt running on one of said pulleys, and means whereby said frame may be bodily shifted on the support for tightening the belt on the other pulley.
