'LEE A. MILLER, OF MILWAUKEE, WISCONSIN, ASSIGNOR TO THE WHEELER &
' VILSON MANUFACTURING COMPANY, OF BRIDGEPORT, CONNECTICUT.
{BOBBIN on UNDER-THREAD CASE-FOR SEWING-MACHINES.
SPECIFICATION forming part of Letters Patent No. 601,837, dated April 5, 1898.
Application inea June 1s, 1897.
To all whom it may concern:
- bin-starter in its outer position.
Be it known that I, LEE A. MILLEE,'of Milwaukee,in the county of Milwaukee and State of Wisconsin, have invented an Improvement in Bobbin or Under-Thread Cases for Sewing- Machines, of which the following description, in connection with the accompanying drawin gs,is a specification, like letters and numerals on the drawings representing like parts.
This invention relates to improvements in bobbin-cases for use in rotary loop-takers or shuttles, my improvements being directed more especially to the addition thereto of devices whereby the bobbin may be started outwardly mechanically when desired.
In accordance with my invention I have combined with the centrally-located stationaryhollow post fast with relation to the back of the bobbin case or extended from said back into the center of the case a bobbinstarter having a shoulder or projection which Y may be moved longitudinally with relation to said post by or through the action of a link occupying a position within said post and loosely connected with a suitable lever which is pivotally mounted on said post, the construction of said parts being such that when the free end of said lever is turned outwardly with relation to the bobbin and bobbin-case the projection of the starter coperating with the inner end of the bobbin will act to start the bobbin out of the case, leaving the head of the bobbin in position to be readily engaged by the operator to be withdrawn from the post, the said bobbin while being taken completely from the bobbin-case passing over the lever.
Figure 1, in front elevation, represents a bobbin-case with my improvements added,the bobbin being removed. Fig. 2 is a sectional detail of the bobbin-case and its contained bobbin. Fig. 3 shows the parts with the bob- Fig. 4 shows a section of the parts represented in Fig. 3, but with the bobbin removed; Fig. 4a, a side elevation of the bobbin-case of Fig. 3. Fig.
' 5 represents the bobbin-case in section with a starter somewhat modified in construction, the 'starter and the actuating -lever being Serial No. 641,263. (No model.)
closed; and Fig. 6 is across-section showing the post and starter of Fig. 5.
The thread or bobbin case a and the bobbin c are and may be substantially such as represented by like letters and` numerals in United States Patent No. 480,181, dated August 2, 1892.
The bobbin-case has a central hollow post a', notched at its outer end and slotted oppo sitely at its two sides, as at d'2. The notchin the outer end of the post receives a pivot b, upon which'is mounted the head of a lever b'. This lever has pivoted to it at b3 a link b4, and the inner end of this link, which is extendedinside the post,is made to embrace the lifting-pin d, the ends of which are extended through the slots a2 in the post, said pin entering the bobbin -starter e. This -bobbinstarter is in Figs. 1 to la represented as a sleeve provided near its inner end with a projection 2, againstwhich rests the inner end of the bobbin c when the bobbin is in position about the post.
When the bobbin-case isin use, the bobbin will be well in the case and the lever b will occupy such a position as to prevent the escape of the bobbin from the post. In Figs. 1 and 2 this lever is shown of a length to eX- tend substantially across the outer face of the bobbin, and the free end of the lever enters a notch 3 (see Fig. 4a) in the edge of the side wall of the bobbin-case.
When the bobbin is to be started out of the bobbincase, the operator will engage and turn the lever b' and in so doing will move the starter e, causing it to be moved outwardly on the post, the projection 2 ot' the starter by its contact With the bobbin starting it outwardly on the post, leaving the outer head of the bobbin in the position to be engaged by the fingers of the operator, so that the bobbin may be taken off the post.
In ream aware I am the first to apply to the post of the thread-case a movable device accessible at the outer face of the bobbin to act against the bobbin and remove it from the open face of the thread-case.
The post a (see Figs. 2 and 3) is also notched, as shown at 4, to leave a space in Which may enter and lie the link b4 when the lever is in its closed position. (See Fig. 2.)
Referring to Figs. 5 and 6, illustrating a modification of my invention, the post f has a slot f,`and the projection f2, constituting the starter for the bobbin, is extended through the said slot, so as to occupy a position under the end of the bobbin. The projection f2 in Figs. 5 and G is shown as forming a part of the link g instead of being in a separate piece from the link, as in Figs. 2 and 3.
In Figs. 5 and 6 a spring h acts to keep the lever closed or open.
I-Iaving fully described my invention, what I claim,and desire to secure by Letters Patent, is-
1. A bobbin-case having a post and a lever mounted on said post, combined With a starting device having a projection to engage the bobbin surrounding said post, and connec-` tions betvveen said lever and starting device to start said bobbin outwardly on said post, substantially as described.
2. A bobbin-case having a post, a starting device presenting a projection outside said post, and a bobbin surrounding said post, and a lever mounted on said post, combined with a link which in the movement of said lever operates said projection, substantially as described.
3. A bobbin-case having a post, a starting device made as a sliding sleeve having a projection, and a bobbin mounted on said sleeve, combined With a lever mounted on said post, and having a link connected with and operating said sleeve, substantially as described.
4. A bobbin-case having a post, a starting device made as a sliding sleeve having a proj ection, and a bobbin mounted on said sleeve, combined with a lever mounted on said post, and having a link connected with and operating said sleeve, said lever being long enough to overlap the bobbin from its center to the edge of the bobbin-case, the end of the lever entering a notch of the said case, substantially as described.
In testimony whereof I have signed my name to this specification in the presence of tWo subscribing Witnesses.
LEE A. MILLER.
