TO ALL WHOM IT MAY CONCERN:

Be it known that I, D. G. MORGAN, of Jordan, in the county of Onondaga, and in the .State of New York, have invented certain new and useful improvements in Window-Curtains; and do hereby declare that the following is a. full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making apart of this speci'dcaticn.

My invention consists in the attachment of a window-curtain in such a manner as to allow the room to be ventilated from the top by the letting down of the curtain: also in the devices' for securing the curtain in the position desired.

In the annexed drawings, A represents the window-frame, to which the roller C, with its curtain B, is attached. These devices are of the usual forms and materials. Upon each side of the window isA placed a metallic plate, a, having an oblong slot its entire length for the insertion of the pivots or tenons a: a: upon the The plates a a may be made of any suitable length, and are attached near the top of the z'z' represent small wire It will be seen ends of the roller. window-frame, so that the curtain can be lowered to the end ofthe slots in the plates.

hooks which are connected to the tenons z :v on the roller, and to the ends of the cords D D1. that this cord is connected to the left side of the windowframe, and passes up over the top of' the curtain through loops c c, or their equivalents. Connected to the main cord (at z) is the cord D, which is secured to the near hook z', while the end of the main cord is\tied to the far hook. G represents a metal rod lso bent as to form a point on its doubled end, and with two small loops at the two ends of the rod (see fig. 3.) This rod or spring is thrust into the side of the frame-for the connection of the lower part of the cord D, to hold the curtain the required distance from the top. It will be seen that the cord is first put into the lcflloop, and thence under and between the sides of the rod, and thence through the right loop, so that the cord -is rigidly held where it is drawn by the weight of the curtain and roller. Upon one side of thc roller C is a. ratchet, y, into which catches the crooked dog m. The cord D2, which is secured to the end of the roller, passes through this dog, and by means of its loop throws the dog from the ratchet and allows the roller to unwind.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

'lhe arrangement of the plates a a, wires it', and cords D D, in combination with the roller O, ratchet y, and dog m, whereby the curtain is raised-or lowered and .secured by the spring-rod, in the manner substantially as and for the purposes specified.

In testimony that I claim the foregoingI have hereunto set my hand this 9th day of March, 18,67.

DAVID G. MORGAN.
