    • 11,861. Lake, H. H., [Schenck,M.B.]. May21. Castors.-The attaching-plate of a sheet-metal roller-bearing castor, which is an improved form of that described in Specification No. 5884, A.D. 1906, is flanged so as to receive a channelled runway ring secured to the pintle, the rollers, guided by an inner runway ring, bearing between the runway ring and the wheel frame, which is held loosely upon the pintle. The attaching-plate 2, Fig. 3, is struck up so as to form two channels concentric with the pintle-hole as shown. An inverted outer cup, of shape corresponding to that of the attaching-plate, has side flanges 15 and an annular flat portion 11, which form a runway and bearing- surface for the stamped sheet-metal rollers 16. The pintle, Fig. 11, has secured firmly together upon it the attaching-plate and runway ring, by forming on it a heavy annular flange 25 seated against the boss 12. The inner runway cup 13 is then placed upon the pintle, the roller bearings being introduced between the two runway rings. The wheel frame is placed upon the projecting end of the pintle, which is upset round a washer 27 holding the parts in position and permitting movement of the wheel frame.
