IMPROVEMENT IN SEWING-MACHINE SHUTTLES.-
Specification forming part of Letters Patent No. l68,067, dated September 2l, 1875 application filed Mayu, 1875.
To all whom it may concern Be it known that I, HUGH LEwIs WALKER, of the town of Guelph, in the county of Wellington, in the Province of Ontario, Canada, machinist, have invented certain new and useful Improvements in Sewing-Machine Shuttles, of which the following is a specication:Y
The objects of the invention are, lirst, to
` lessen the cost of manufacturing the shuttle 5 second, to facilitate the threading of the same; and, third, to provide an even, smooth tension, easily regulated and adjusted without the assistance of a screw-driver or any such tool. These objects are secured by simplifying the construction ofthe shuttle by dispensing with all set-screws for regulating the tension and centers for holding the bobbin; also in obtainingthe tension by passing the thread between two spring-plates, which are riveted together, and are hinged to the shuttle, forming a cover for it and a holder of the bobbin, 'substantially as hereinafter described.
Figure 1, plan without spring-cover; Fig. 2, plan with cover; Fig. 3, longitudinal section; Fig. 4, elevation; Fig. 5,-transverse section.
A is the body of the shuttle, in which the bobbin B lies. G-is the top spring-plate, held to the bottoni spring-plate D by the rivet d. The two thus held together are hinged onthe pin b to the shuttle A, the hinge being formed by the pin b passing between the two spring-plates C and D, the end c of the latter .being shaped as shown, so as to form the desired hinge. E is the thread-hole in the shuttle, and F is a notch cut in the plate C, which serves thepurpose of a funnel to guide the thread through the hole E, the bridge G assisting in the action. The end H of the plate D is bent down, and when the lid of the shuttle formed by the two plates D and O is closed this bent end H presses l against the end of the bobbin, holding it in position, the notch f fitting over the shank of any desired tension it has been adjusted to, which adjustment and operation of the shuttle are effected as follows: Open the shuttle-lid formed by the two spring-plates C and D, and push the bobbin B into its place, as indicated by drawing; slip the thread I between these two plates, the shape of the end H facilitating this operation. When the thread is thus placed slide it up toward the rivet d. The stiffer the tension required the nearer must the thread be to the said rivet. When the thread I is in the desired position draw it into the notch it is opposite to, it being remembered that the thread must enter in the notched side of plate. When thus adjusted close the lid of the shuttle and pass the thread I through the eye E, the notch. F in the plate G making the operation extremely easy to accomplish. rlhe threading is now complete, and it will be found that not.
centers required to hold the bobbin in position, and no screw-driver necessary to regulate the tension; that should the spring-plate C and D be broken, or otherwise require renewing, no mechanical skill is required to take it oft' the shuttle and put another, which may be obtained from the factory, in its place; and, nally, that when the lid is closed the bobbin is securely locked in its proper position.
I claim as my invention-f l. The spring-plate D, having the notches a, the slotted bent end H, and the bridge Gr, combined with the spring-plate G, provided with the notch F, said plates being fastened together and pivoted to the shuttle, substantially as and for `the purposes speciied.
TE" Erica 2. The sprimgf-plante` C, having the slot h, and spring-plate D, provided with the slot f, pivoted to 'the shuttle and riveted together, as shown, combined with the bobbiu B and ,pin g, substantially as and for the purposes specified.
3. The shuttle-body A, provided with theV pin g,in combination with the plate C, having 'alle slot h, substantially as and for the purpose specified.
