I at 2i forming an upper bearing surface and a lower bearing surface 26 connected together by a circular driving neck portion 27, which neck portion is adapted to fit into the notches 19 in the flange l8 driven thereby as the quoit rotates.

By this construction it will. be seen that the flange 18 extends into the groove or space 24: between the upper and lower bearing members of the carrier thereby presenting a carrier-simporting surface the extent of which is illustrated by the shade lines at 28 in Figure 4 and as this surface moves with the carrier the driving friction on the latter is reduced to the minimum.

By my improved construction it will be seen that I have obtained a number of important advantages in the operation of a braidin machine; first, the quoit members are made to rotate and are provided with very broad engaging peripheral surfaces which cooperate with a similar supporting surface on the carrier to hold the carrier in an upright position and prevent it from tipping or swaying from side to side as it is moved rapidly through the serpentine raceway; second, I engage the guiding surface of the carrier about midway between its upper and lower guiding members and thus balance the frictional resistance between the upper and lower guiding surfaces due to exerting a driving pressure at a point substantially in the center thereof.

y my improved construction of braiding machine I am enabled to drive the carriers at a very high velocity and by supporting the carriers against an oscillating motion I am enabled to produce a high quality of work which is uniform in character.

By the term broad or extended as applied to the supporting surface of the quoits and carriers, in both the specification and claims, I wish to be understood as meaning av supporting or hearing with a substantial distance between its upper and lower bearing edges and the bearing or contacting portion of the surface itself may or may not be continuous between these edges.

The foregoing description is directed solely towards .the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which thedevice is susceptible, the invention being defined and limited. only by the terms of the appended claims.
