    • 13,333. Hill, J. S. June 15. Window blinds.- Relates to brackets for supporting the ends of b l i n d rollers and also for guiding the cord or tape, and to roller ends. The end a', Fig. 3, of the roller A is made in one piece of metal or other material to form the pulley round which the cord is wound. The cord C is passed through a hole b in the fitting B, the sides of which form a guide for the cord. The pivot a of the roller passes through an opening b in the side of the fitting B, the side having also a recessed part b to receive the end of the roller and prevent the cord from slipping between it and the casing. In some cases the roller A has a long tubular pin or pivot a , Fig. 5, which acts as the pulley and which may have a hole or slot a for the attachment of the cord or tape. The opening b , Fig. 7, through which the cord passes, may be provided with rollers F for the cord to run on. The fittings B are provided with plates having stud holes which engage with studs on plates secured to the window frame ; the fittings may also be screwed to the window frames. The brackets for the ends of the rollers are made with recesses which cover the extreme ends of the pivots, or the pivots may form part of the brackets and fit into holes in the ends of the rollers. The pivots are made from round metal or othar material pointed or screwed at one end. Where holes are made in the ends of the rollers, ferrules may be employed instead of pivots. The fittings may be applied at the right, left, or top of the window frame.
