SHUTTLE.
Patented dan. li, 1918.
Original application iled February 5, 1915, Serial No. 19,209. Divided and this application le'May 28, 1917. Serial No. 171,132.
To all 107mm 'it mag/ronccrn:
lle it known that l, JONAS Non-Timor, a citizen ot the United States, residing at Hopedale, in the county of Worcester and State ot' Massachusetts, have invented cer: tain new and useful improvements in Shuttles; and I do hereby declare the following to he a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. A
The present invention relates to an improvement in shuttles for looms, and more )articularly to an improvement in the bobliin or filling carrier holding jaws of selftlireading shuttles for automatic looms.`
The present 'application is a division of application Serial N. 19,209, filed February 5, i915.
Bobbin holding springs, as commonly constructed heretofore, have been of heavy Iforged steel and machined into the proper shape to" secure the requisite resiliency. rlhis method of constructing the springs is expensive. lt has, accordingly, been proposed to reduce the expense in the production of bobbiii holding springs by making them of iiat stock bent into the required shape. @ne difficulty hitherto experienced inthe use of lat stock for bobbin holding springs has lain in the fact that they have not possessed the necessary resiliency. The object of the present invention, theret'ore, consists in constructing bobbin holding springs of fiat stock in such a manner as to secure the necessary resiliency. f
The preferred form of the invention is illust-rated in the accompanying drawings, in which Figure 1 is a top plan of the thread, delivery and bobbin holding ends of a shuttle with the middle portion thereotA removed,
showing the application of the structure of y the present invention to the, bobbin holding end of the shuttle; Fig. 2 is a longitudinal sect-ion of the bobbin holding end of the shuttle, partly in elevation; and Fig. 3 v
is a sec'tion on line 3 3 of Fig. 1.
In the illustrated embodiment of the invention the shuttle 5 is, in general, of the usual form of construction, having an elon- `ated bobbin recess 6, and is provided at its thread delivery end with a threading block designated generally by the reference character B. The threading block is held in place by a screw7 7 vwhich passes through va slot formed transverselyl in the bottom construction. At the bobbin holding end of the shuttle, bobbin holding springs 0r jaws l0 are provided which constitute the subject-matter of the present invention.
The bobbin holding'javvs or springs 10 are made of a strip of flat stock, the ends being bent lul-shaped, the bottom of the U being somewhat elongated into anarrow neck 11 and receiving between the depressed sides a block l2 for solidity. The neck 11 of the holding jaws is receivedl in a recess in the bobhinholding end of the shuttle and secured therein by the screw 13. The parallel sides of' the jaws are provided with notches or recesses 15 into which are received the rings on the bobbin in the usual manner for holding the bobbin in operative position. Heretofore, bobbin holding jaws constructed .of dat-'stock have lacked the resiliency .of
.of both jaws so tliat the chamt'er tapers gradually from about the point 16 at the base ot' cach jaw to about the point 17, from whence outward to their ends the sides of the-jaws -run parallelly. From the point A17 the cha nifer or bevel. proceeds to the ends ot' the jaws parallel with their top edges. The result of chamfering the jaws in this manner, as it is obvious, is the removal of the greater amount of stock from the extrem-- ity of the jaws Where'the greater resiliency4 desired and the/'lesser amount of .stoc from` the base"of )the jaws where a lesser resiliency and agreater strength are desired. Bobbin-holding jaws constructed in this Imanner have all the advantages of jaws constructed of forged .steel machined into proper shape. Another advantage of the bevel or chamfer on the top inside edges of the sides of the bobbin-holding jaws lies in the ready entrance it affords to the bobbin during thc filling replenishii'icnt.
As indicated in the preamble, the present while being especially Having thus described the present invention, what is Claimed as new is:-
l. .l loom shuttle for the automatic inserion of a fillingr 'carrier or bobbin, having lil-shaped liohhn holding jaws, recesses in he jaws for maintaining the bobbin in op ei'ative position, and deep chamfers on the op inside edges of the parallel sides for the ieady, inseition of bhe bobbin.
2. A loomshuttle for the automatic inser- Lion of alling carrier o1' bobbin, having '1J-shaped bobbin holding jaws, recesses in he jaws for maintaining the bobbin in operative position, and a ehamfer on 'the top inside edges of the jaws beginning at the bottoni of the rounded portion of the jaws and tapering downwardly to aloouiI the parallel sides of the jaws, 'from which point to the ends of the jaws the chamfer runs parallel with the top edgesoz` the jaws for imparting the proper resiliency to the jaw's.
3. A loom. shuttle having, in combination, U-shaped bobbin holding jaws, recesses in the jaws for maintaining the bobbin in operative position, and alohamfer on the top inside edges of the jaws `tapering gradually from Athe botto the jaws to abou the beginnin of the/ pan allel sides of the jaws, from w ich point to the ends of the jawshe chamfer runs substantially parallel with the top edges of the jaws. v
