ORANGE VENNEE, "OF BELFAST, MAINE.
i'lVlPRVEMENT IN SWINGMACHINES.
Specification forming part of Letters Patent No. 133,814, dated December l0, 1872.
To all whomt't may concern:
Be it known that I, ORANGE VENNER, of
lBelfast, in the county of Waldo and State of Maine, have invented certain new and usefulV p Description of therAccompaitg/ing Drawing.
Figure 1 is a plan, `showing the movable shuttle-race block; also a part of the table T T, the shuttle-race block being represented in the position it will occupy when the machine forms the shuttle-stitch. Fig. 2 shows a sec- .tion of the shuttle-race block, and also the looping device, the parts being in position for action as a shuttle-machine, the looper performing no function; Figs. 3 and A being the same as l and 2, except the parts are in position for action as a loop-stitch machine. Fig. 5 shows the looper in connection with the movable shuttle-race block. Fig. 6 shows the shut# tie-race block and its adjuncts from the under side.
General Description..
A is av shuttle-race blockattached to the table of the machine by the screw a, Figs. l,
`3, and 6, and is arranged so as to swing on said screw as a pivot'from the position represented in Figs. 1 and 2 to that of Figs. 3 and A. To the shuttle-race block A the guard B is attached, as shown, soas to form a shuttle# race, the shuttle being driven by the swin gin g arm H K. The net adle-throaty or channel c, Figs. l, 3, and 6, shown in section in Figs. 2 and 4, is divided, by a'movable plate, Nl N,
' into two parts, C and D, Figs.2 and 4. When the shuttle is to be used the shuttle-race block A and the division-plate N occupy the position shown in Figs. l, 2, and 6, the plate forming the back of the needle-throat. When in this position the plate cuts off all communication between the needle and the looper, and although the looper is in mot-ion it can have no effect upon the thread. When the looper is to act the shuttlerac'e block A is swung over to occupy the position shown in Figs. 3 and 4, the plate N1 N being withdrawn so as to allow the needle to operate in connection with the looper E to form the loop-stitch. The plate NlN is connected to the bent lever N2, which, in its turn, is pivoted to the lug M affixed to the body of the machine, so that the side move ment of the shuttle-race block A will cause a corresponding longitudinal movement of the plate N]L N. Thus, when the shuttle-race block A is swung over to the position indicated in Fig. 3, then the plate N1 N is withdrawn from the groovein the shuttle-race block, into which the needle Works, as shown in Fig. 3, the converse of this being also true. The looper E is attached to a hanger on the shuttle-race block A, and is free to move on the cam G, so that it is always in action, though doing no work except when the shuttle-race block is in position for sewing by the loop-stitch.
The character of my invention is such that I have a machine that may be made to sew either a loop or lock stitch by simply changing the relative positions of parts ofthe same machine.` This change may be effected by simply moving the shuttle-race block A and the plate Nl N, as already described, or by allowing it to remain stationary and moving the plate N1 N and the needle-bar, pressure-foot, and their adjuncts.
The combination of parts in my invention is a changing one-that is, the needle is a constant element, while the shuttle-race and the looping device alternate as elements.' This ,alternate combination may be effected by moving the needle or by moving the shuttle-race block, which embraces the shuttle and looping devices.
I claim as my invention- V l. The combination of the movable shuttle race block with the reciprocating plate N1 N, operating to divide the needle-throat G D, subA stantially as described, and for the purpose set forth.
2. The'cornbination of the movable shuttlerace block A, the'vertical looper E, and the 'link F with the cam G, arranged substantially as described, and for the kpurpose set forth. ORANGE VENNER.
