The annexed figures represent an improvements in Castors, invented bv J. Hanley, No. 10 North "William street, New York Gity. Figure 1 represents a section of the frame of the castor, with section of the cap upon it Fig 2 is a section of the wheel or roller, showing it and the journals cast in one piece. The same" lettefcr refer to like parts. The frame, A, of the castor and its axis, B; is made in one piece The axis, B, is of a conkal' shape and has a broad base, C ; the apex terminates with a pin, D, which is of wrought-iron and inserted in the mould of the casting, and is thus moulded along with the axis. The end of this pin passes through the centre of as to hold the frame and the cap together, but ! allows the frame to revolve in the cap. The frame, A, is made with two channels, F (one only shown) cast in it, to answer for beariijH ofG G, to the wheel or roller H io work The wheel or roller is secured in its pla * I the pins, I I, of wrought non whic ! moulded in the casting; these pins ar* lw i*j over the journals of the wheel, as shown by the dotted lines, and it is thus secured in its place. The wheel or roller, H, is cast with, journals in one piece. The cojimon castors toe no conical upper axis, but a straight one siWeil in the cap by a transverse pin; the [ axes or journals of the common rastor rolle are a separate spindle, not cast along with the wheel. The evident improvements of this castor for furniture will be plain to every cabinet or furniture maker Measures have been taken to secure a pa tent.
