When the flat end portion is fully seated, arms l1 and I8 rest in grooves B and 9, hook members i9 and 2% are seated in recesses l0 and Il and vertical portion l5 of the loop member is seated in groove l2 formed across the end of the base of the guide. By means of this arrangement, the guide. is readily and easily placed upon its support and held in the operative position by means of the loop. The longitudinal recess formed in the base of the guide is preferably of substantially the same cross section as the flattened portion 4 of the support arm so that a snug seat is provided when the liat portion is seated in the recess.

Referring to Figs. 5 and 6 there is shown a mod iiied form of thread guide and support therefor, wherein the angular position. of the guide with respect to its support may be adjusted so that the tension. on the thread can. be varied. It will be noted in this arrangement that support member l is provided with a cylindrical end portion 2l and an intermediate iiat portion 4 between the plain cylindrical end 2| and threaded portion 3 of the support. The thread guide is of substantially the same conguration as the guide used in connection with support member shown in Figure 1; however, it differs therefrom in that the recess 22 formed longitudinally of the base of the guide is cylindrically shaped and adapted to receive the cylindrical end 2l of the support member. The guide isy further provided with a cylindrical shaped base having a plurality of grooves 23 formed exteriorly thereof and corresponding diametrically opposite grooves I2 across the end of the base portion, grooves I2 being adapted to receive section i6 of the loop when the guide member is mounted upon its support.

It will be appreciated that the transverse or diametrically opposite grooves l2 may be eliminated, since the guide can` be supported and held in the operative position on the support member by means of the engagement of the arms I1 and i8 of the loop with grooves 23 in which they are adapted to seat. By means of this arrangement, the angular position of the thread guide may be changed so as to vary the tension on the thread. As; in the arrangement shown in Figure 1, the guide is placed in the operative position by inserting it on the support member with the plain cylindrical end 2l in recess 22 formed in the base of the guide and permitting arms I1 and I3 to seat in a pair of grooves 273, ends I9 and 2B of the loop member being seated` in recesses l0 and Il formed at the ends of the grooves. In order to vary the tension on the thread, the position of the guide with respect to support member 3 is varied by rotating it so that a different pair of grooves 23 are brought into position to receive the arms of the looped member.

While I have shown and described the preferred embodiment of my invention, I wish it to be understood that I do not confine myself to the precise details: of construction herein set forth, by way of illustrations, as it is apparent that many changes and variations may be made therein, by those skilled in the art, without departing from the spirit of the invention, or exceeding the scope of the appended claims.
