of access, at the lower part of the window.

These hooks c, c, takeinto dead eyes d el. on the lower -head A, and thus suspend the lower kto the upper head.

m m (Fig. 8,) are hooks arranged inthe i brackets, for catching into the plates fn., on the lower head, and supporting it when drawn up against the upper head, said hooks `being held against said plates by the springs s. To the top of one of the hooks m, is attached a cord p, which passing across the top of the upper head, runs over a pulley placed in the ltop of the opposite hook, thence down through the bracket, to some point of easy access. As the lower head rests in these hooks m, when it is in place, and as a simple drawing of the cord p, (as seen `in Fig. 6) will draw both these hooks -back `from the plates n, it is obvious that,

were it not for the cords, and hooks c, and dead eyes d, the lower head with its appendages would drop down. When the hooks are withdrawn, the cord to which the lower head is then suspended, is lowered away, and the blind is let down. 'The' hooks c, c, may be then taken out ofl the dead eyes `.0l d, and the main part of the blind may be removed, it being entirely detached from the upper head. The upper head may be also lifted from its supports, and the whole blind is removed and as readily replaced again. On the "upper head are placed guide rods t, t, which hang down a little below said head, and when the lower head with its slats is being raised into place these guide rods take into grooves u in the sides of the lower head, and direct said lower head into its place. As the lower head is drawn up against .the hooks m, said hooks spread out against the action of the springs s, until the plates n on the ends of the lower head rise up above t-he catches on said hooks. At this point the springs s, force the hooks under the plates n, andthe blind is firmly held in its place. Y

In the gures 9, 10, ll, 12, 2', 8', and 4', is represented a modified form of construction, where the brackets are not used.v In these figures A', is the lower head, and B', the upper one.

` m', m', are the hooks, which are hung in the upperhead, and catch over pins e', a', in the lower head.V These hooks are held up to the pins a', by the springs s', behind case may be let down as in the irst described plan from which it differs nothing in principle, and scarcely anything in detail, and need not be described in detail, as the drawings fully illustrate it.

Having thus fully described the nat-ure of my invention, what lf claim therein as IleW and desire to secure by Letters Patent is- 15 In combination with the lower head and blind, the additional or upper head, and the hooks and cords, for readily connecting or disconnecting the two heads, for the purpose of placing, or removing the blind from the window, substantially as described and represented.
