FILLING-CARRIER FOR LOOMS.
SPECIFICATION forming part of Letters Patent No. 691,816, dated January 28, 1902. Original application filed November 8, 1898, $eria1No- 695,880. Divided and this application filed August 23. 1901. Serial To all whom it may concern: 7
Be it known that I, HARRY W. SMITH, a citizen of the United States, residing at North Grafton, in the county of Worcester and State of Massachusetts, have invented an Improvement in Filling-Carriers for Looms, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings repre- I ing it has been found that all'the filling cannot be unwound from the filling-carrier during the weaving, as the end is liable to be left in the web between the selvages, thus producing what i n the trade is called secthis action of the aukiliary mechanism is of veryconsiderable impo'rt-ance,and looms have ends, and consequently attemptshave been made to bring the auxiliary mechanism into action when the filling has beenexhausted to a predetermined point prior to complete exhaustion, The loss of filling resulting from been provided with feelers to contact with the filling on a filling-carrier at the forward movement of the lay, and when the diameter of the filling mass has been sufficiently reduced the feeler by its near approach to the longitudinal center of the filling-carrier permits certain devices controlled by the feeler to be started to supplynew filling andeject' the filling-carrier from whi'chthe fillinghas been practically exhausted.
Theobject of the present invention is the production of awound mass of'filling wherein maybe secured a reserve quantity of filling to one side of a detecting means'after the working filling on the carrier has become practically exhausted and wherein also the amount of waste filling may be determined stance as embodying my'invention consists'of ,derstood in the art',and the end of theyarn will (No model.)
ing is subsequently wound, so thatin the op- 55? I eration of weaving the detecting means is and must be uncovered just prior to the unwinding of that portion of the filling first unwound,
or the initial windings, to thus indicate the quantity of reserve filling or'w'aste remaining on the carrier. The filling-carrier th s generally outlined and having the detectinginember is adapted for use inany loom having an auxiliary mechanisnn-suchas stopping or changing nechanism, controlled bya feeler--' as, for instance, one having a magnetic feeler g adapted to be coupledwith the detecting member, which is of magneticmateriahor with a feeler adapted to close an electric circuit by contact with saiddetecting member.
my invention. Fig.2 is a longitudinalsec ti'on thereof, showingithe manner of laying the initial windings onth'e carrier; and Fig. 3 is a" longitudinal sectional'viewofla filling-Q carrier. 1 I
The weft-carriershown in the present-ina bobbin having-any 'usual cylindrical body or section 1, a conical baset2, and a head 3.
V Referring to the drawings, Figure lis a side View of'one form of filling-carrierembodying Preferably adjacent the head 3 andnear the I T base of the conical section 20f the bobbini's a detecting means, preferably'in the form of a metallic band 4,an'd contiguous tovsaidband is formed in the material of the bobbin a depression or groove 5. I I
" In winding the'filling on=the carrier the latterwill be placed ona spindle, as is well un-' beconnected with thebarrel of the carrier at one side of the detecting means or member 4:, preferably at that side thereof between the band and the small or' delivery'end ot' the bobbin, and'the bobbin being then rotated the thread-guide, of whateverform', Will DQ111310- tained in such position with relation to the bobbin as to wind thereon at one side of the detecting member a series of distinctive initial windings c, which will determine the amount of reserve filling or waste, the said initial windings on the form of bobbin shown IOO being laid upon the conical base portion 2 of the bobbin and into the groove 5. Then sufficient yarn has been laid on the bobbin to one side of the detecting member or band 4 to constitute the desired quantity of reserve filling on the bobbin after the detecting member in the operation of weaving has becoine uncovered, the traverse of the thread-guide is caused to lay the yarn over the detecting member one or a plural number of times and to thereafter regularly lay the yarn in the usual and well-known manner, as shown in Fig. 3.
It will be evident that when a filling-carrier or bobbin is provided with a groove, as 5, in proximity to the detecting member such groove may in some instances be sufficiently large in itself to contain what I have termed the initial windings to form a supply of reserve filling or waste after the detecting member has been uncovered, or such initial windings may extend, as has been above explained, not only in the groove 5, but along the filling-supporting surface of the carrier, and while I have shown in the present embodiment of my invention the groove for containing a part or all of the initial windings to constitute the reserve supply of filling of course it is evident that such groove is not essential, the initial windings being carried by the filling-supporting surface of the bobbin to one side of the detecting means or member. It will be also obvious to one skilled in the art that the particular form of bobbin selected for illustration of my invention is not essential, nor is it necessary that the detecting member or band 4 shall be located at the base ofthe conical section 2 of the bobbin, as variations in the form and distribution of these parts may be made within the scope of myinvention.
A bobbin provided with a detecting means or member and wound, as described, with the distinctive initial windings at one side of said member constitutes a new and very desirable article of manufacture, which may be used with profit to people run ninglooms in the manufacture of cloth.
I believe I am the first to devise a bobbin adapted to be held stationary, said bobbin having a detecting means or memberbetween its ends, said means or member being located on the bobbin preferably, though not necessarily, near its head or base, and thereby adapted to have the yarn wound thereon by distinctive initial windings to one side of the detecting member and thereafter upon said detecting member.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-
1. A filling-carrier provided with detecting means and having a distinctive initial wind of filling on said carrier to one side of the detecting means, the filling being thereafter wound upon the carrier to cover saiddetecting means and permit the filling to be delivered from the end of the carrier whereby the detecting means may be uncovered as thefilling is being unwound and prior to complete exhaustion of the filling.
2. A filling-carrier provided with a metallic band and having a distinctive initial wind of filling on said carrier to one side of the metallic band, the filling being thereafter wound upon the carrier to cover said metallic band and permit the filling to be delivered from the end of the carrier whereby the metallic band may be uncovered as the filling is being unwound and prior to complete exhaustion thereof.
3. A bobbin provided with adetecting member and a groove, and having the filling initially wound to fill said groove and thereafter wound to cover said detecting member,whereby in unwinding the filling the detecting member will be uncovered before the initial windings are unwound from the groove.
4. A fillingcarrier provided with detecting means and having a distinctive initial wind of filling on said carrier to one side of the detecting means, the filling being thereafter wound upon the carrier in conical layers to cover said detecting means and to permit the filling to be delivered from the end of the carrier whereby the detecting means may be uncovered as the filling is being unwound and prior to complete exhaustion thereof.
5. A filling-carrier provided with a conical base and detecting means secured to said base and having a distinctive initial wind of filling on said carrier to one side of the detecting means,the filling beingthereafter wound upon the carrier to cover said detecting means and permit the filling to be delivered from the end of the carrier whereby the detecting means may be uncovered as the filling is being unwound and prior to complete exhaustion thereof.
6. A bobbin provided with a groove and a metallic detector member,the groove containing a quantity of filling to constitute waste, the detector member being overlaid with filling which may be unwound therefrom'prior to the complete unwinding of the filling from said groove.
In testimony whereof I have signed my name to this specification in the presence 0 two subscribing witnesses.
