UNITED STATES PATENT OFFICE.
PHILIP DIEI-IL, OF ELIZABETH, NEIV JERSEY, ASSIGNOR TO THE SINGER MANUFACTURING COMPANY OF NE\V JERSEY.
SEWING-MACHINE SHUTTLE.
SPECIFICATION ferming part of Letters Patent No. 375,695, dated December 27, 1887. Application filed June 14, 1886. Serial No. 205,109. (No model.)' I
To rtZZ whom it may concern.-
Be it known that I, PHILIP DIEHL, a citizen of the United States, residing at Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in SewingMachine Shuttles, of which the following is a specification, reference being had therein to the accompanying drawings.
The object of my invention is to provide a sewing-machine shuttle of such construction that it is adapted to carry a large amount of thread in proportion to the size of loop required for it to pass through, as well as a shuttle which will be very convenient for use and easily threaded, my invention being more par ticularly designed as an improvement on that class of shuttles which are segmental in form and which in operation have an oscillating or rotary movement.
In carrying my invention into effect I provide the frame or body of the shuttle with a bobbincase, which is preferably cylindrical in form, open at its rear end, and pivoted at its forward end to said frame or body. In the preferred form of my inventiontlie said bobbincase has an open -ended threading'slot leading into a thread-delivery hole, the latter being beneath a tension-spring secured to the outer side of the case. The bobbincase, being pivoted to the body of the shuttle,
is thus adapted to be swung aside for the insertion or removal of the bobbin, and when returned to its operative position is held in place by a spring-catch. The bobbin-case is arranged lengthwise of the segmental frame, rim, or body of the shuttle; or, in other words, in such a manner as to form or partly form a chord of an arc of the circle of which the said rim or body is a segment.
In order that myinvention may be fully understood by those skilled in the art to which it relates, I will fully describe the same in connection with the accompanying drawings, in which- Figure 1 is a side view of one form of my invention, and Figs. 2 and 3 plan views of the same with the beak in section. Fig. 4 is an cndview,and Figs.5 and 6 are sectional views, of the same. Fig. 7 is a plan View, with the beak in section, of a slightly different form of my invention from that shown in the preceding figures; and Fig.8 is a similar view of the same with the tensionspring removed. Fig. 9 is a side view, partly broken out, of still another form of my invention; and Fig. 10 is a cross section of the tension-spring shown in Fig. 7 on the line 10 10 in the latter figure.
A denotes the frame or body of the shuttle, and B the bobbin-case, the latter being preferably cylindrical in form with a tapered or pointed forward end, at which part it is secured-to the frame or body A by a pivot-pin, a, so that it may be swung outward, as shown in Fig. 3, for the insertion or removal of the bobbin, said case being open at its rear end for this purpose. If desired, however, the bobbin-case may be pivoted to the frame or body A at or near its center.
To hold the pivoted bobbiu case in its operative position, I provide a spring or springcatch, 0, secured in a recess, d, in the inner side of the frame A, the free end of said spring engaging said case by a slight recess at e in the latter, said free end entering a hole,f, in the said frame to prevent the lateraldisplacement of the spring by the friction of the bobbincase against the same. The bobbin-case is provided at its rear end with a shoulder, g,which, when the said case is swung into operative position, comes into contact with the heel-piece or arm h on the shuttle-frame A, the said shoulder thus forming a stop for the said case.
0 is the tensionspring, secured to the outer.
side of the bobbin-case by an attaching and adjusting screw, 2', and j is a threadingslot, preferably open at its rear end, as shown,said slotleading into a threaddeliveryhole, k, beneath the tension-spring. In the form of my invention shown in Figs. 1, 2, and 3 the slot 9' is outside of the tensionspring and extends forward nearly or quite to the front end of the bobbinchamber, running thence diagonally rearward intothe thread-delivery hole, thetension-spring having a thread-finger, the point of which enters a slight recess in the bobbincase; but in the form of my invention shown in Figs. 7 and 8 the threading slot is entirely beneath the tension-spring and is straight, and the delivery-hole into which the said slot opens is about midway lengthwise of thebobbin-chamber. Also, in this latter form of my invention the tension -spring overlying the threading-slot and delivery-hole has an inclined rear end to guide the thread into a holding-notch, 12, formed in an inwardly-turned lip, m, entering a slot, 0, in the bobbin-case. With this construction the shuttle is threaded very easily by a single slight pull on the thread to draw thelatter along the threading-slot and into the delivery-hole and the holding-notch, .the latter securely preventing the escape of the thread from beneath the tension-spring.
The pivot-pin a, by which the bobbin-case is attached to the shuttle frame or body, may be easily driven out to permit of the removal of the case from said body when for any reason it is desired to detach these parts, as when the said frame or body (on which most of the wear comes) is worn out, so that it becomes necessary to renew it, or when it may be desirable, owing to the class of work being performed, to substitute a bobbin-case different in its construction or having a different form of tensionspring for the bobbin-case formerly in use. The bobbin-case may, however, be rendered detachable from the shuttle frame or body by constructing these parts as shown in Fig. 9, in which the said case is represented as being provided with a pointed nose, 1), entering a recess in the said frame, the rear arm, d, on the latter being made very light, so that it will spring to allow the said case to be snapped into operative position, said arm thus serving as a springcatch to hold the bobbin-case in place.
The tapered or pointed forward end of the bobbin-case serves as a spreader to carry the loops of needle-thread over the said case, this construction permitting of the use of a comparatively large bobbin case with a narrow segmental shuttle frame or body to run in the shuttle-race, so that a bobbin capable of carrying a large amount of thread may be used in a shuttle not requiring a very large loop of needle-thread for it to pass through.
Having thus described my invention,I claim and desire to secure by Letters Patent- 1. In a sewing-machine shuttle, the combination, with a segmental rim or body, of an independent cylindrical bobbincase attached to the said rim or body and arranged lengthwise thereof, or so as to form a chord of an arc of the circle of which the said rim or body is a segment, the said bobbin-case being tapered or pointed at its forward end for easy passage through the loops of needle-thread, and open at its rear end for the insertion of a bobbin, substantially as set forth.
2. In a sewing-machine shuttle, the combination, with a segmental rim or body, of a cylindrical bobbin-case detachably secured to the said rim or body and arranged lengthwise thereof, or so as to form a chord of an arc of the circle of which the said rim or body 1s a segment, substantially as set forth.
3. Asewing-machine shuttle having a cylindrical and detachable bobbin case which is tapered or pointed at its forward end for easy passage through the loops of needle-thread and open at its rear end for the insertion of the bobbin, combined with a spring-catch to assist in retaining the said case in the rim or body of the shuttle. i
4. A sewing-machine shuttlehavingaeylmdrical bobbin-case which is tapered or pointed at its forward end and open at its rear end,the said bobbin-case being pivoted at its forward or tapered end to the rim or body of the shuttle, combined with a spring-catch to hold the free or rear end of the said bobbinease in operative position.
5. A sewing machine shuttle rim or body and a cylindrical bobbin-case having a pointed or tapered forward end, at which it is pivoted to the said rim or body, and an open rear end for the insertion of the bobbin, the said case having also a shoulder or stop, as g, and the said body having an arm against which the said shoulder or stop impinges, combined with a spring-catch to engage the said bobbin-case and retain it in operative position.
6. The combination, with the shuttle rim or body A, having the recess d, of the springcatch 0, secured in said recess, and the cylindrical bobbin-case having a tapered or pointed forward end, at which it is pivoted to the said rim or body, said case being engaged at its rear end to be held in operative position by the free end of the said spring catch.
7. Asewingmachineshuttle having an openended bobbin-case provided with a thread-delivery hole, athreading slot, and a second slot, combined with a tension spring having a notched inwardly-turned lip extending into said second slot, substantially as set forth.
8. A sewing-machine shuttle having an openended bobbin-case provided with a thread-delivery hole, a threading slot, and a second slot, combined with a tension spring having a notched inwardlyturned lip extending intov said second slot and an inclined rear end, sub stantially as set forth. 7
In testimony whereof I affix my signaturein presence of two witnesses.
