v Be it lrnown thet I, Crmnnns Pn'rzoinn, e citizen ol -the Un ted States, residing at Providence, county of Providence, State of- Rh ode island, have invented an Improyement in lland 'lhreadlng Shuttles, of wh ch the following description, in connection Withthe accompanying drawing, is especification like characters on the drawing representing like parts. i
This invention relates to hand-threading sln-ittles and has for its object to provide it simple threading device which can be inexpensively manufactured; which will not 001 lei-t or gzzther lint; which will also-be efiica cums in removing slubs or knots frorn the 'ing' which occupies shuttle; Fig. 7 is a fragmentary View show- .inp; u dill'orcnt en'ibodhnent of the invention;
1 designates the body of the shuttle Whichis provided with the usual bobbin-receiving thread as it is drawn from the shuttle, and which has other features of improvement, all as will. be more fully hereinafter described and then pointed out in the appended claims. i
Reilerringio the drawings wherein l have illustrated one embodiment of my invention,
Figure 1 is a plenvvicw ofon'e end of a shuttle embodying my invention; Fig. 2 1s 1 side view of Fig. 1; Fig., 3 is e-section on the line were, Fig/15 F g. 441s a sectionon: the line Q y, F 13;. Figs. 5 and 6 are perspective views of the threed-deliveryhushthe deli-very eye of the recess 2 and with a delivery eye 3 through which the yarn or thread is delivered. The
. thread is led into the delivery eye through a thread guiding passage formed in the Wall of the shuttle, this passage comprising the:
vertical portion e which extends from the top of the shuttle down part way through the body thereof, and the horizontel portion.
5 which forms a communicating passage be tween the vertical portion land the shuttle eye The inner end 6 of the Vertical'por tion 4 of the thread-guiding passage is preferably located on the opposite side of the axial line of the shuttleor bobbin receiving recess from the outer end of said portion s, so that this vertical portion crosses. said axial line,
The thread-delivery eye-3 is formed in a thread-delivery bushing 7 which is inserted into an opening-formed. in thesi-de of the shuttle. This thread-delivery bushing is of special shape and construction. It is tubu- PatentedMa-y 20,1913.
i nd thebore thereof constitutes the delivery eye 3. With a longitudinal threading slot 8 and the outer Wall of the bushing on one side of the slot is cut away; asat Q thereby to form a The bushing 7 is providedcurved passageway 10 which leads from the horizontal portion 5 of the threading passage to the threading slot 8. The bushing 7 isof such a length that the inner end thereof issituated beyond the axial line of the shuttle or bobbin receivingrecess, and the inner end 11 of the bushing isinclined to the axis thereof, the inclination being parallel With the portion 4 of passage and coming approximately in alinenie'nt therewith.
substantially the" threading The bushing is also provided with the knot-catching slot- 12 in th side thereof which faces the ing' chamber 2, this slot '12 extending i'rom the inner end of the bushing toapproxi mately the' axisl-line of the shuttle The Wall of the shuttle is provided with the groove or recess 14 and the ou'ter zend l3.-
' of thebushing comes substantiallyfinsh-with thebottoin of. the groove or recess 14: The
bobbin-reeeivbushing is also cute-Way on its outer end 13,
as shown at '15," ah the point Where the --threeding slot 8 is situated, and the size of the aperture in whieh the bushing is'resolved, or what is the same thing, the, exterior diameter of the bushing, is substantially the same as the Width of the recess 14.
As a'result, when the bushing is in place the outer end of the threading slot 18 will stand at a considerable distance from the portionand the latter will form a prevent the shuttle eye 160i the shuttle, guard which tendsto from (lo-threading.
At the end of'the bobbin-receiving recess 2 the shuttle is cut away to form a; fiat surfacel7 which is situated just below theknotcatching slot 12. In threading the shuttle follows that the thread will beheld inlthe passage it ;.the thread is laid into the vertical portion 4.5 qf the threading passage, and then drawn "through the horizontal portion 5 thereof slot) 12 as it is drawn ofi' from the bobbin. If'the thread should have a knot or stub therein which would be likely to make an imperfection in the cloth, such knot or slub Will catch in the slot 12 thereby breaking the thread and causing the loom to be stopped through the usual stopping mechanism.
Itwill be noted that my device is ex;
tremely simple and can be readily put into the shuttle. Moreover, I have demonstrated from experiments that my threading device will not gather lint as many threading devices do.
I propose to provide the delivery bushing with an aperture which .opens into the bobbin-receiving chamber. The purpose of this aperture is to make the shuttle anonsucking one. The practice of threading a shuttle by sucking the thread through the shuttle eye is deleterious to the health and by providing the thread-delivery bushing With the aperture 20 it is impossible for an operator to thread the shuttle by sucking therethrough. v
The threading slot 8 may be formed-either in the upper or the under side of the thread delivery bushing 3. In Fig.2 I have shown it as formed in the under side of the bushing, and in Fig. 7 as formed in the upper threading passage leading to saideye, said passage comprising a vertical portion extending from the bobbin-receiving chamber outwardly, and a horizontal portion connecting the vertical portion with said eye, a thread-delivery bushing in said eye having a threaded slotin its under side which conimunicates with the threading passage, the
inner end of said bushing extending beyond the axial line ofthe bobbin-receiving chamher and being formed with an inclined face extending substantially parallel to the vertical inclined port-ion of the threading passage, said bushing having in its side facing the bobbin-receiving chamber a knot-catching slot which extends from the inner end of the bushing approximately to said axial line.

2. A hand-threading shuttle having a' thread-delivery bushing in. said eye, the in= ner end of said bushing extending Jeyond the axialfline of the shuttle, said bushing having a knot-catching slot extending from its inner end outwardly and situated on the side thereof facing the bobbin-receiving chamber, and also having an aperture 'between the knot-catching slot and its delivery end, which aperture prevents the thread from'being drawn into the eye by suction,
In testimony whereof, I have signed my name to this specification, in the presence of two subscribing Witnesses.
