TATTING SHUTTLE Filed May 4, 1945 Patented May 20, 1947 TATTIN G SHUTTLE Gustav A. Carlson, Chicago, Ill., assignor to The Boye Needle Company, Chicago, 111., a corporation of Illinois Application May 4, 1945, Serial No. 591,954

'7 Claims. 1

This invention relates to a tatting shuttle, and more particularly to a tatting shuttle possessing improved features which contribute to the ease and efficiency of the use of the shuttle.

An object of the invention is to provide a simple efficient tatting shuttle of improved construction. Another object is to provide a tatting shuttle having the arms thereof arranged to provide lead grooves for the thread for greater ease in winding the thread on the shuttle. Yet another object is to provide in the arms of a tatting shuttle, lead grooves at the ends thereof extending from the upper and lower sides of the arms. A further object is to provide in a tatting shuttle an integral pointed arcuate end for use in forming picots.

Other features and advantages will appear from the following specification and drawing, in which Fig. 1 is a side elevational View of the improved tatting shuttle; Fig. 2 is a similar side elevational view showing the thread wound on the core of the shuttle; Fig. 3 is a sectional view taken along the line 3-3 of Fig. 1; and Fig. 4 is an end elevational View taken along'the line 4-4 of Fig. 1.

In the embodiment of the invention described herein, the shuttle possesses a frame I having a core H for receiving a threadwinding. Preferably, the entire structure is made of a resinous material, such as a synthetic resin, although any suitable material may be used.

The core H for receiving the thread winding may be of any suitable size or shape and, as illustrated, consists of a fiat plate having end surfaces It and i3 above which the thread is wound. If desired, the core II as shown may be provided with small holes I4 and I5 which may be used to anchor the end of the thread. Thus, the thread may be passed successively through the two holes and the end tied to the body of the thread to provide a loop.

A pair of integral arms l6 and I1 extend for wardly from opposite ends of the core II in opposed adjacent relation. These arms extend toward each other so as to provide at their ends relatively narrow dimensions so that the shuttle may be readily passed through the loop of thread held on the fingers in the tatting operation.

Another pair of arms I 8 and I9 extend rearwardly from opposite ends of the core in opposed adjacent relation. The arms [8 and i9 are simv ilar to the arms l6 and I1 except that the arm l9 is provided with an elongated arcuate pointed .2 end 20 which extends beyond the end of the opposing arm I8.

The pointed end 2!! is used in drawing a thread through a picot, the end being passed into the picot to engage the thread, and then being withdrawn to carry the thread with it through the picot.

The inner surfaces 2| and 22 of each of the forwardly-extending arms I6 and I! extend rearwardly from the end of the arm toward the core and are each inclined toward the adjacent opposed surface of the other arm, thus providing a tapered thread-receiving groove of a maximum width at the ends of the arms. As illustrated,

the groove is substantially V-shaped and provides a lead for the thread when it is being wound on the shuttle. Similarly, the inner surfaces 23 and 24 of the rearwardly-extending arms 18 and I9 are each inclined toward the opposed'adjacent surface of the other arm to provide a similar groove at this end of the shuttle.

The arms [6, ll, l8 and I9 may also be provided with inclined rounded or beveled surfaces at their upper and lower sides to provide threadreceiving grooves at these portions of the ends of the arms. As seen particularly in Fig. 3, the inner surface of the arm l6 may be inclined from its upper edge 25 downwardly and toward the arm ll. The surface may be rounded as shown at 26. Similarly, the inner surface of the arm I! may be inclined from its upper edge 21 downwardly and toward the arm 16, as shown at 28. The same surface of the arm I! may be inclined from its lower edge 29 upwardly and t ward the arm 16, as seen at 30. Similarly, the inner surface of the arm l6 may be inclined from its lower edge 3! upwardly and toward the arm IT, as seen at 32. In this way, thread-receiving grooves having a maximum width at the upper and lower edges of the arms are provided for leading the thread when the thread is to be wound on the core. Similar grooves may be provided by the arms 18 and 19, as seen in Fig. 4, the arm It! being provided with the inclined surfaces 33 and 34 and the arm l8 being provided with the inclined surfaces 35 and 36.

As illustrated the core of the shuttle is substantially rectangular at the horizontal plane and has substantially fiat upper and lower sur faces only slightly spaced apart to provide a relatively thin core body. Each pair of arms forms a continuation of the core. Each of the arms is also thick in substantially the same plane as the core and is provided with substantially fiat upper and lower surfaces.

In use, the thread is secured to the core H by passing it through the holes [4 and I5 and forming a loop through these holes, and is then wound about the core to provide a threaded shuttle, as seen in Fig. 2. In the winding of the thread about the core, the thread is passed between the adjacent arms [6 and I1 and between the adjacent arms l8 and 19. The thread engages the substantially V-shaped grooves formed at the ends of each pair of arms and also at the upper and lower sides of each of the pair of arms. In this way, any tendency for the thread to fail to pass between the arms in the course of a rapid winding operation is minimized.

The tatting operation is carried out in the usual manner, with the shuttle being passed through the loop of thread which is formed on the fingers of the user. When the thread is to be passed through a picot, the pointed end 29 is inserted in the picot and engages the thread. The pointed end is then withdrawn and draws with it the thread which is then brought through the picot.

Although the invention has been described in connection with a specific embodiment, it will be apparent that modifications and changes may be made without department from the spirit and scope of the invention.

I claim:
