'TATTING SHUTTLE.

Application filed June 6,

T all whom it may concern:

Be it known that I, Gnsrev A. CARLsoN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Tatting Shuttles, of Which the following is a specification.

This invention relates particularly to tatting shuttles; and the primary object is to provide an improved tatting shuttle which is capable of being cheaply manufactured and which operates in an improved manner. The invention is illustrated, in its pre ferred embodiment, in the accompanying drawing, in which Fig. 1 represents a' plan view ofv the improved tatting shuttle; Fig. 2, an edge view, partly in section; Fig. 3, a section taken as indicated at line 3 of Fig. 1; Fig. 4:, an enlarged broken section taken as indicated at line 4 of Fig. 1; Fig. 5, a view showing the bobbin removed from the housing and applied to one extremity of the frame for winding purposes; and Fig. 6,

a view of the blank employed in making the frame of the tatting shuttle.

In the construction illustrated, A represents the frame of the shuttle; and B, a demountable spool or bobbin housed in said frame. i

The frame A preferably is formed from light sheet-metal, being integral in formation. It comprises a pair of resilient pointed side members 1 and 2. In stamping these side members form a strip of sheet-metal, the side members are left connected at one end by a reduced strip 3 which forms, when th strip is bent upon itself, one extremity of the frame or shuttle.

The line upon which the metal is bent is indicated by the dotted line 3 in Fig. 6. The side member 1 is provided at one extremity with a crochet hook i, which is stamped from the sheet-metal and is integral with the side member. At the base portion of the hook there are provided lateral notches 5. The member 2 is provided at its free end with lateral projections 6 which are adapted to be bent into engagement with the notches 5 and clenched against the side of the neck portion which is flanked by the notches 5. The manner in which the free ends of the side members 1 and 2 are connected together will be readily understood from Figs. 1, 4, and 6.

The edges of the side members 1 and 2 1921. Serial No. 475,407.

are suitably curved to give the double point ed form to the frame; and the side members of the frame are bowed apart in the manner shown in Fig. 5. At their central portions, the bows 1 and 2 are provided with inwardly struck embossments 1 and 2 as clearly appears from F These embossments serve as trunnions for the bobbin B.

The bobbin 1)) comprises a tubular portion or drum 7 and. flanges or disks 7 secured on the ends thereof. The flanges 7 are made conc a-vocoiivex, the edge portions of the flanges being curved away from the sides of the frame. The ends of the barrel '7 engage the trunnions 1 and 2 and the flanges of the bobbin are free from engagement with the bows of the frame. In inserting the bobbin, the bows are sprung apart. The ronstruction'is such that when the bobbin is inserted, the compression caused by expanding the resilient side members 1 and 2 is exerted on the ends of the barrel 7, so that only a moderate amount of friction is created. This permits the bobbin to be turned with considerable freedom to enable the thread to be unwound as the tatting operation is carried on. Near the hook-equipped end of the frame A the bows 1 and 2 are provided with registering sets of

perforations

8, 9 and 10 thru which the thread 11 may be passed in any desired manner, to give the desired tension upon the thread. By selecting the manner of passing the thread thru the perforations, the tension may be varied to suit the operator.

When it is necessary to rewind the bobbin, it may be readily removed from the frame and its barrel may be forced onto the end of the frame which is afforded by the folded reduced neck portion 3. It will be noted that the lateral edges of these reduced portions are substantially straight and their width corresponds approximately with the inner diameter of the barrel of the bobbin. When the bobbin is forced onto the reduced end extension of the frame, in the manner shown in Fig.5, the resilient side members are forced together somewhat. owing to the curvature of the interior of the barrel. Thus, the bobbin is held upon the extremity of the frame by strong frictional resistance. The user may therefore hold the frame in the fingers of one hand and may wind thread upon the bobbin while the shuttle frame serves as a holder for the bobbin, the frictional resistance between the bobbin and the missible in view of the prior art.

What I regard as new, and desire to secure by Letters Patent, is

1. A tatting shuttle formed of a single strip of sheet material and comprising a pair of bows united at one end by a reduced neck portion the strip being folded on itself at said neck portion and, one of said bows being equipped at its free end with a hook, means securlng the free end portions of the bows together, and a bobbin mounted between said bows.

- '2. A tatting shuttle comprising a pair of bows which are united at one end by an inte gral reduced neck portion, the free end of one of said bows being equipped with a hook and the free end of the other of said bows being equipped with clenching lugs serving to secure the free end portions together, and a bobbin mounted between said bows.

A tatting shuttle comprising a pair of bows having at one end an integral neck portion connecting the bows, the free end of one of said bows being equipped with a hook and adjacent thereto with lateral recesses and the free end of the other how being equipped with clenching lugs engaging said accesses, and a bobbin mounted between said ows.

4. A tatting shuttle having a frame comprising a pair of bows, said frame being equipped at one end with a hook and at the opposite end with a bobbin-mounting, and a bobbin removably mounted between said bows, said bobbin being adapted to be fitted on the bobbin-mounting at one end of the frame.

5. A tatting shuttle comprising a frame having bows united at one end by a reduced neck affording a mounting for. a bobbin, said frame being equipped at the opposite end with a hook and said bows being provided with trunnions, and a bobbin comprising a barrel and flanges, the ends of said barrel engaging said trunnions, said bobbin being removable and capable of being mounted on the reduced neck at the end of said frame.

6. A tatting shuttle comprising a pair of bows affording. a frame having a hook at one end, said bows being provided near said hook with a series of perforations affording uides for a thread, inwardly struck embossments at the central portions of said bows aifording trunnions, and a bobbin comprising a barrel and flanges, the ends of said barrel engaging said trunnions and the flanges of the barrel being free from engagement with the adjacent surfaces of the bows. 7. A ta-tting shuttle comprising a frame having bows united at one end by areduced neck affording a mounting for a bobbin, said frame being equipped at the opposite end with a hook and said bows being provided with trunnion-bosses, and a bobbin comprising a barrel and concavo-convex flanges, the ends of said barrel engaginglsaid trunnions, said bobbin being removable and capable of being mounted on the reduced neck at theend of said frame.
