IMPROVEMENT IN SEWING-MACHINES.
Specication forming part of Letters Patent No. 134,209, dated December 24, 1872.
of the city of Montreal, in the district of Montreal, in the Province of Quebec, Canada, have invented certain new and useful Improvements on the Shuttle-Slides for Sewing-Machines; and I do hereby declare that the following is a full,.clear, and exact description of the same.
This invention has reference to improvements on that class of sewingmachines in which shuttles are used, to obviate the diiiculty that often occurs from the slide covering the hole in the table for the shuttle to travel in becoming displaced while the machine is in full operation, thereby allowing the shuttle, by the tension oi' the thread at the extremity of its stroke, to be raised out of place in the shuttle-carrier and lodged upon its extremity. Whenever this occurs, the shuttle, in moving forward, comes in contact with the needleplate of the machine, where it is firmly jammed, causing one of the following accidents to occur, viz: Either the driving-stud must break; the shuttle be crushed; the needle-plate be bent or broken; or the gears or other driving mechanism be broken 5 or the whole of the above-mentioned partsv may be more or less represents a front elevation of Fig. l, Fig. 3
represents a modification; and Fig. 4 represents a modification.
Letter a is a portion of the entablature, of any configuration, in'Which are placed the slides 'b and c, covering the opening in the table a, in which the shuttle travels. d is the needle plate or throat. In the form ot' bedplate of sewin g-machine shown in the drawing, b is the slide covering the shuttle at the back of the stroke, to prevent which from slipping out of place, as aforesaid, I provide a lockplate, e, pivoted at e to the bed a. This lockplate e is provided with a notch,f, engaging with a button-headed stud, g, and any suitable projection, h, for turning it up in the position shown in dotted lines in Fig. l. To prevent it from bein g turned altogether back, and thus forgotten to be turned to the proper position to prevent the slide b from coming out, the spur t is provided, so that it is rendered necessary for the operator to put the lock-plate in the proper position before beginning the Work.
Another modication of the lock-plate e is shown in Figs. 3 and 4. Here a recess, Zt, is formed in the bed a to receive it, and it is Worked by a nger-nail recess, Z, the projection of bed at m answering the purposes of the spur i in Fig. l. The object of this moditication is to do away with any projection beyond the outline of the bed a, by which the Work being operated upon may be caught. It will be easily understood that where the direction of the plates b and c is that ofthe line A B in Fig. l the same arrangement may be applied.
What I claim as my invention is as follows:
l. The plate b, in combination with lockplate c, constructed, arranged, and operating substantially as described.
2. The plate b, in combination with lockplate e with spur i, substantially as set forth.
