LoUIs LUDWIG, or PHILADELI'HIA, PENNSYLVANIA SHUTTLEKAND BOBBIN Application med May 31.

This invention relates toa shuttle and bobbin arrangement, the gene'ralobjectl of the invention being to provide a shuttle having means therein for supporting a plurality of bobbins, With the thread or yarn so arranged on the bobbins that when one bobbin is empty7 the thread or yarn Will be drawn from another bobbin and this will continue until all the bobbins are empty7 so that it is not necessaryto stop the loom to replace a bobbin at `frequent intervals, as is the case Where but one bobbin is used.

Another object of the invention is to provide means for stopping the loom When the l thread from the last bobbin has been removed 'herefrom This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.y

ln describing'the invention in detail, referen ce will be had to the accompanying drawings Wnerein like characters denote like or corresponding parts throughout the several views, and in Which- Figure 1 is a top plan view, with parts in section7 of the improved shuttle, With the bobbins therein.

Figure 2 is a side view.

Figure 3 is a section on line 3-3 of Figure 1. Figure 4 is a fragmentary plan View, With parts in section.

Figure 5 is a section on line 5-5 of Fig-" ure 4.

Figure 6 is a section on line 6-6 of Figure 4.

Figure 7 is a section on line 7-7 of Figure 6.

Figure 8 is a section on line 8 8 of Figure 4.

Figure 9 is a perspective view of one of the atch means.

Figure 10 is a perspective view of the rear Y end of a bobbin.

v In these drawings, the letter A indicates a shuttle which is of suficient length to be vthat the loom Will be stopped.

divided into a number of bobbin chambers 1, so that a plurality of bobbins B can be carried by the shuttle. The partitions 2 Which divide the shuttle into the bobbin chambers are each formed with a centrally located hole throughwvhich a tube 3 passes, this tube being suitably held in the hole and has a part projecting beyond the partition so that this projecting part will enter the` enlarged part of the bore 4 of the bobbin which is arranged in the base thereof. Each of said partitions also forms a support for the latch member 8 for engaging the annular groove 9 in the base of the bobbin. Each latch member is of angle shape in cross section, with the pins 10 carried by onelimb of the member, these pins passing into the holes 11 extending vertically throughv `the partition and a spring 12 is located on each pin and engages a part of the partition and a projection on the pin .so that these springs tend to hold the latch member in latching engagement With the bobbin. rlChe base of each bobbin is formed With a number of diagonally arranged holes 'or passages 13 therein which have their inner ends communicating With the bore adjacent the tube 3 so that the thread passing through the tube can pass forwardly at an angle through one of these passages and then be Wrapped aroundthe bobbin in the usual manner.

A spool 14 is rotatably arranged in a chamber 15 formed in one end of the shuttle in rear of the last bobbin to be unwound and a. pair of contacts 16 is placed in the chamber and is insulated from the shuttle and these contactsy are electrically connected With any suit-able form of stop means for the loom. The spool carries a bridge piece 17 which, when the spool is moved to a certain position, will bridge the contacts 16 and thus complete the circuitto the stopping device so @ne end of the thread or yarn is fastened to the spool afterthe same is placed in a position with its bridging piece 17 out of engagement with the contacts, as shown in Figures 1 and 4. The thread or yarn is then passed through -thefirst tube 3 and through one of the passages 18 in the first bobbin and is then CTI one side or" the shuttle and the yarnpasses from the chamber through a -hole24 arranged at the center oi 'the shuttle.

From the foregoing it will be seen that the yarn is hrst drawn Jrom the bobbin located adjacent the friction brush and then when this bobbin `is empty, the yarn is drawn `from the next bobbin and so on until all the bobbins are empty. As soon as the rst bobbin is empty, or that bobbin which is next to the spool le, the pull of the yarnwill cause the spool to turn so that the bridge piece 17 will bridge the contacts, thus completing the circuit to the stopping device so that the loom will be stopped. The latchL means are then raised so that tie empty bobbins can be removed and tall ones substituted therefor. By passing the yarn through the chamber 28, there is no danger of the yarn leaving the shuttle being interfered with by the yarn leaving the bobbin.

Thus I have provided simple means whereby the loom can be run for a long time without stopping the same to renew the bobbins.

It is thought from the foregoing description that the advantages and novel features ot he invention will be readily apparent.-

lt is to be understood that changes may be made in the construction and in the combination and arrangement oi the several parts, provided that such changes all within the scope oi the appended claims.

What I claim is l. A shuttle of the class described comprising a plurality or' bobbins arranged in the shuttle, the yarn on the bobbins being connected together in a continuous manner whereby when one bobbin is empty, the yarn will be drawn from the next bobbin, and a cir'- cuit closer for a loom stopping device fin the shuttle and operated by the yarn when the last bobbin is empty. l f Y 2. A shuttle of the class described comprising` a number of bobbin chambers, a bobbin in each chamber, means whereby the arn from one bobbin passes to the next bobbin so that the yarn is continuous and a circuitV closer'ior a loom stopping device in the shuttle and operated by the yarn when the last bobbin is empty. v

3. A shuttle having a number of partitions thereindividing the same into a number of bobbin chambers, a tubular member carried `whereby yarn can pass through each tubular member and the passage and be wrappedV around the bobbin, a circuitcloser for a loom stopping device in the shuttle and operated bythe yarn when the last bobbin is empty, and latchmeanscarried by each partition for holding a bobbin in position. Y K 4L.l A shuttle having a number of partitions therein dividing the same into a number of bobbin chambers, a tubular member carried by each partition and entering apart of eachbobbin, each bobbinihaving a diagonally arranged passage',A in its base leading from, the tubular member to the exterior of the bobbin wherebyyarn .can pass through each tubular member and the passage and be wrapped around the bobbin, latch means carried by each partition for holding a bobbinV in position, a circuit closer for a loom stopping device in the shuttle in rear of the last bobbin and to which the yarn is connected, whereby the yarn will move the closer to a position for closing a circuit of the loom stopping device whenl the last bobbin is empty.

5. A shuttle having a number of partitions therein dividing the same into a number of bobbin chambers, a tubular member carried by each partition and entering a part of each bobbin, each bobbin having a diagonally ari ranged passage in its base leading from the tubularmember'to the exterior of the bob-V bin wherebyv yarn can pass throughl each tubular member and the passage and be wrappedaround the bobbin, latch means carried bypveach partition for holding a bobbin in position, one side of the shuttle having a passage through which the yarn passes from the rst bobbin, a circuit closer for a loom stopping device-in the shuttle and operated by the yarn when the last bobbin is empty, and friction means carried by theshuttle and engaging the yarn kafter it leaves the first bobbin. Y

In testimony whereof I affix my signature.

LOUIS LUDWIG.
