Specification of Letters Patent.
Patented Apr. 11, 1916.
Application led June 12, 1913. Serial No.`7.73,187.
To all whom it may concern Ee it known that PHILIP Diem., late a citizen of the United States residing at Elizabeth, in the county of Union and State of New Jersey, and MARTIN HEMLEn, a citizen of the United States, residing at Elizabeth, in the county and State aforesaid, did invent certain new and useful Improvements in Sewing-Machine Loop-Takers, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention has for its object to provide a loop-taker of that type in which the thread-cassis journaled within the loopseizing member and is either wholly or partially removable therefrom for renewal of the mass of lower thread or for threading and adjustment of the lower thread tension.
Owing to the described relation of the relatively movable parts, it is important that the thread-case should. bemade as light as possible; and to this end, in a preferred embodiment of the present improvement the thread-case is constructed to omit the usual axial bobbin supporting pin and the central portion of the bottom of the thread-case which sustains the same. In thread-cases composed of separable sections locked together by means of latch devices such as that of the pending application of P. Diehl and M. Hemleb Serial No. 662,595, it has been customary to provide the body section not only with a bottom member sustaining an axial journal-pin, but to provide the cap member with a tubular bobbinsupporting post fitted to the journal-pin; but according to the present construction such pin and post are dispensed with, thereby materially lightening the bobbin-case.
Another desideratum of a thread-case is to secure a substantially direct lead of the .lower thread from beneath the tension spring to the work without passing around any abrupt corners. Ancording to the present improvement, the thread is led through the lower side wall of the thread-case and the outer face almost diametrically beneath a flat tension spring, thence through a delivery eye near the upper periphery of the outer face of the case and through a guide-channel in the holding lug in practice engaged by a stationary member of the machine for restraining the thread-case against turning, the thread being led from such channel directly to the work. By this means, a uniform tension of the thread is assured and untwisting and kinking are pre` vented.
The invention will be understood by reference to the accompanying drawings, in which- Figure 1 is an outer face view of a looptaker embodying the present improvements, and Fig. 2 an edge View of the same with the loop-seizing member insection. Fig. 3 is a transverse sectional view of the threadcase. Fig. 4 is a perspective,V view of the body section, Fig. 5 an inner face view of the cap section, and Fig. 6 a perspective view of the cap section with the tension spring and latch member omitted. Fig. 7 is a perspective View of the tension spring, Fig. 8 a similar View of a plate formed with the thread-delivery aperture, and Fig. 9 is a perspective view of the latch member.
The loop-seizing or hook-member is shown formed of a ring 1 connected by radial arms 2 with the hub 3 adapted to be secured upon a rotary actuating shaft. As described in our said application, the member 1 is cut away upon one side of its periphery and provided with the beak 4 and loop-deflector 5. This member is cup-shaped to afford an axial thread-cavity G in whose side Wall is formed an annular groove 7.
As herein represented` the sectional thread-case is composed of the cylindrical body section 8 provided with the segmental rib or flange 9 fitted within the groove 7 of the hook member, and the cap section which is formed with the cylindrical side-wall 10 and outer end wall 11. The cylindrical sidewall of the cap section is fitted within that of the body section 8 with its extremity resting against an annular shoulder provided therefor, The cap and body sections together inclose a cylindrical space which is uninterrupted between its ends both axially and diametrically to alford a thread-cavity to receive the lower thread bobbin 12; and the body section is formed as a, cylindrical shell open at both ends and having at its inner end, or that opposite the closed end of the cap section, the narrow inturned flange 13 serving to confine the adjacent flange of the bobbin 12 in position.
The body section 8 is provided in the upper portion of its periphery with the outwardly and upwardly projecting holding lng 14 having the radial channel 15 adapted to be entered by a fixed holding element sustained by the machine frame. In one side of its periphery. this body section is formed with a slot 16 terminating at the outer end in a notch 17 in a lateral flange or projection 18. The flange 9 is interrupted at one side of the section 8 to afford the usual loop-detaining shoulder 19 against which the needle-thread loop is carried by the hook 4 in casting the same about the lower thread.
The wall 10 of the cap section is provided in one side with the threading slit 20 eX- tending from the inner edge and terminating intermediate the edges in the aperture 21. The outer end of the cap section is shown provided with a lateral rib 22 formed with a thread-guiding notch 23 in substantial alinement with the slit 20 and connected therewith by means of the groove 24.
At the opposite side from the notch 23 of the end disk 11 of the cap section and nearly diametrieally opposite. is the flat plate 25 secured in position by rivets 2G and formed with an inclined slot 27 terminating in the tlnead-delivery aperture 28, thereby producing a laterally extending tongue 29. As represented in the drawings, the outer face ot' the tongue 29 is substantially flush with that of the end disk 11, and the extremity of this tongue is outwardly inclined at 29. as represented in Figs. (i and S to freely admit the lower thread beneath the same in threading. A transverse channel 30 is formed in the outer facel of the member 11 intermediate the notch 23 and tlu'ead-deli\'ery aperture 28 in which is secured by means of the screw 31 the flat tension spring 32, the bottom of the channel affording a countersunk seat disposed below the out-er face of the plate 25.
As shown in Fignri, the lower thread 1 leading from the bobbin passes through the thread aperture 2l and thence through the groove 2l and notch 23 along the bottom of the channel 30 and beneath the plate 25 to the delivery aperture 28 from which it emerges in its passage to the under side of the work. As represented in Fig. 1. the cap Section is so disposed relativeiy to the bottom section of the thread-case that the notch 23 and delivery aperture 28 are in substantial alinement with the channel ifi of the holding lug 14 through which the thread is adapted to be led in a nearly direct line from the tension spring through the usual needle 10 aperture in the throat-plate to thewori. To insure this relation of the separable bin-case. sections, the ril:- 22 is cat s. one side to afford shoulders 'n i gage the opposite edges of the i' z 14 as represented in Figs. l and ln order to detachably secure the cap tion to the body section, a iat-ch device employed which is similar to that of United States patent to Vi". Brandi. 557.547, of April 7, 1896. The member i. is shown formed with the undercut spaced parallel ribs 33 and 34 disposed transversely to the tension spring 32, t-he rib 34 being formed with a socket 35 to receive the spring 8B 86 (shown in dotted lines, in Figs. 1 and Fitted to these ribs along the opposite edges is the sliding latchplate 37 provided with the lateral lug to receive the thrust of ,the spring 36, and with the inturned nger 9@ 39 having the wedge-shaped extremity 40 and the latch shoulder 4-1 adapted to enter the slot 16 of the body section and to engage the projection 18. as represented partiioularly inFigs, 2 and 3. A clearance aperture l2 is formed in the side wall and end member 11 of the cap section to accommodate the slide-plate and its finger 39.
At the end opposite the finger 39 the latch-plate S7 is forked and provi(Y i? with i bosses 43 to receive the pin 44 which aordff a pivotal connection of the latch-plate the tongue 45 attached to the finger-piece The member 11 is formed with the aperture Je? to admit the tongue l5 which latter, when the iingenpiece 46 is raised, acts upon the cross-bar -18 intermediate the apertures 42 and +7 of the member 11 to force the latex plate 87 baelrwardly so as to disengage the finger 39 from the projection 18 of the thread-case section 8. The head of a stopscrew 49 upon the inner face of the latchplate 37 engages the cross-bar 4S to limit the retractive movement of the iatchas to hold the finger-piece 4G rigid for use a handle in withdrawing th ip section for renewing the bobbin or for other purposes.
ln applying a bobbin to the cap section, as herein represented. the bobbin is introduced and the thread drawn through the threading slit 2O into the aperture 21, after which it is led through the notch 23 between the adjacent edges of the spring 32 and channel 30, and thencel forwardly beyond the extremity of the tongue 29 and laterally toward the delivery aperture 28. In this clined point ot' the tongue upwardly 35 cured, and
40 cylindrical thread-cavity 55 ing a loop-seizing lateral movement., the thread is directed by an upturned lip 32 of the spring adjacent the tongue 29 downwardly so as to lead from the bottom of the channel beneath the' in- 2S), under which it is drawn into the delivery aperture. In the casting of the needle-thread loop about the thread-case in the production of the first stitch of a series. the lower thread is drawn to the under side of the work, being thus caused to pass through the channel of the holding lug 14 so as to assume nearly a direct lead from the tension spring 32 to the work and thereby avoid the tend- 15 ency to untwisting and kinking to which it has been subjected in loop-takers of other construction.
Vhile the present improvement is herein shown and described in what is considered its preferred form, itis obvious that it may be readily adapted to other types of looptaker than thatk of the present embodiment and that it is susceptible of material modification in constructive features without depai-ture from the scope of the invention.
