2 Claims.

This invention relates to a separable shield for a rosette forming device. It is generally known in the art that the present method of making rosettes is unsatisfactory. In general this method consists of using a device which is provided with a plurality of spaced radial pin members, applying a series of looped threads diametrically across opposite pin members, and thence tying each of the looped threads together by means of an additional thread member However, in this process, the thread member used to tie each of the looped threads together has a tendency to catch on the exposed points; when this happens the operator must first free the thread before proceeding. I have found, however, that by means of the use of a separable shield member placed over said looped threads, this disadvantage can be eliminated.

The invention will be further described by reference to the accompanying drawing which are made a part of this specification.

Fig. 1 is a bottom plan view of the separable shield of this invention.

Fig. 2 is a sectional view of the shield of this invention taken on lines 2-2 of Fig. 1.

Fig. 3 is a top plan view of the shield of this invention.

Fig. 4 is a drawing showing the conventional method of tying together the looped threads in the conventional method of making rosettes showing how the tying thread catches on the exposed spaced radial pin members when the conventional method of making rosettes is used.

Fig. 5 is a. drawing showing how the catching of the tying thread on the spaced radial pin members is avoided by the use of thi invention.

The conventional rosette forming device, which is shown in Figs. 4 and 5, is formed with a plurality of spaced radial pin members I0. Threads II are looped diametrically across opposite pin members I0. Additional thread I2, secured to needle I 3 is used to tie each of threads I I together after threads I I are looped over pin members It so as to form one unit. It is noted that in this conventional process the radial pin members of the rosette forming machine are necessarily in extended position since the threads II must be held in place. Where tying thread I2 i used to tie threads I I to each other it has a tendency to catch upon the exposed points of pin members I 0. Such catching in the conventional process is shown in Fig. 4 of the drawings. The catching of the tying thread upon the exposed radial pin members as previously set forth is a great disadvantage since the operator of the machine must stop work and clear the thread before proceeding. The present invention, therefore, provides a separable shield member which is adapted to be placed over the underside of the exposed pin members of the conventional rosette forming device while the tying thread is being used to tie the threads disposed across the upper side of the pin members. After the tying thread has been placed in position the separable shield is removed, the pin members retracted, and the completed rosette removed from the machine.

Shield member I4, which comprises this invention, is formed with a hole 6 in the center thereof. Preferably also the outer face I! of shield I 4 is inwardly tapering with the portion containing hole 6 being the highest portion of shield I4.

The underside I6 of shield I4 is formed with a flattened circular portion 5 adjacent to hole 6 and an additional circular portion 4 surrounding circular portion 5. Shield member I4 is provided with a plurality of spaced radial grooves 2 which are adapted to cover the underside of pin members I0 when the device is in use.

The operation of this device in the manufacture of rosettes will now be explained.

The conventional rosette forming machine which is provided with retractable pins, is obtained and the pin members I0 thereof extended. A plurality of threads I I are then looped over opposite pin members II] to form the skeleton of the rosette.

An additional thread I2 is then disposed upon needle I3. Shield member I4 is then placed in position to cover the underside of the exposed points of pins IIl. Thread I2 is then wound over threads I I as shown in Fig. 5 of the drawing and is adapted to secure thread II to each other so as to form a rosette. After thread I2 has been wound about threads I I the excess is cut off and shield I4 is removed from pin members I0. Pin members It are then retracted and the completed rosette is removed from the machine.

The foregoing specific modifications of this invention are for illustrative purposes and for DurpOses of example only. Various changes and modifications can obviously be made within the spirit and scope of this invention and will occur to those skilled in this art.

I claim:

1. In a rosette forming machine provided with a plurality of spaced retractable radial pin members, a separable shield member adapted to cover the underside of said spaced radial pin members when said pin members are extended and a plurality of threads are disposed upon said pin members; said shield member being provided with a plurality of spaced radial grooves upon the undersurface thereof and a hole in the center thereof.

2. In a rosette forming machine provided with a plurality of spaced retractable radial pin members, a separable shield member adapted to cover the underside of said spaced radial pin members when said pin members are extended and a plurality of threads are disposed upon said pin mem bers; said shield member being provided with a hole in the center thereof, said shield member being also formed with an inwardly tapering outer face, a flattened circular portion on the underside thereof adjacent to said hole, an additional radial grooves.
