CHENEYREED AND ELIAS HOlVE, JR.,'OF CAMBRIDGEPORT, MASSACHUSETTS.

APPARATUS FOR OPENING AND CLOSING BLIN'DS Specification forming part of Letters Patent No. 6,748, dated September 25, 1849.

To all whom it may concern:

Be it known that we, CHENEY REED and ELIAS HOWE, J r., both of Cambridgeport, in the county of Middlesex and State of Massachusetts, have invented a new and useful Apparatus for Opening and Closing Vindow- Blinds, dto.; W'ithout Raising the Sash, and we do hereby declare that the following desoription, taken in connection with the accompanying drawings, hereinafter referred to, forms a full and exact specification of the same, wherein we have set forth the nature and principles of our said invention, by which it may be distinguished from others of a similar class, together with such parts as we claim and desire to have secured to us by Letters Patent.

The figures of the accompanying plate of drawings represent our invention.

Figure l is an exterior elevation of a narrow window-frame and asingle blind hinged thereto with our new apparatus attached. Fig. 2 is avertical section of the same, taken in the plane of the line A B, Fig. 1; and Fig. 3 is a horizontal section taken in the plane of the line C D, Fig. l.

By recent inventions the same object and result have been aimed at and attained as `in use, and must eventually7 supercede them.

a a. b b are the two sides of the windowframe. c is the cap, and d the sill, of the frame, constructed and put together as shown in the drawings or in any other suitable manner.

e e e e is the blind, which ishung or hinged to the side da of the window-frame by means of the two common hinges fg, Figs. l and 2. Just above the lower hinge and secured to the saine side rail of the blind to which the sock ets of the hinges are attached is firmly fasti vened the right-angular metallic cleat 7L h.

(Shown partly by dotted lilies in Fig. 3.) A

horizontal arm t' t' is cast on one side of this cleat, so as to project out some distance from the side rail of the blind in the direction shown in Figs. 1 and 3, and said arm has an elongated oval slot or space lc formed near its outer end, as shown in the drawings. A lever-arm Z (cast on and projecting at right angles from a'horizontal sliding and turning rod fm, fm) tits near its lower end into the slot 7o of the horizontal arm @'12, as shown in the several drawings. The rod m m moves forward and back and turns in a proper hole or bearing bored through the side a a of the windowframe, and this rod should be so arranged as that its axis shall be in the same vertical plane with the axes of the two hinges by which the blind is hung. One end of the rod m m projects into the interior of the apartment and has a knob ot fitted thereon, and from the above-described connection of parts it will readily be seen that by moving said rod m m in and out and turning it a little in its bearings the blind may be moved at pleasure in either direction and be under entire and perfect control from the room while the sash is closed.

In order to fasten the blinds when opened or closed, we cut a notch o in proper position on two sides of the turning rod m m and form a proper mortise across the side ct ct of the window-frame, in which we insert a common latch p 1J, which turns on a fulcrum or pin q, and is shown by dotted lines in Fig. l and in section in Figs. 2 and 3, and said latch falls into the aforesaid notches when the blind is opened or closed, and of course fastens it in either position.

It will be evident from inspection of the drawings of our improved apparatus that the slotted arm t t' may be cast on t-he plate rrof the lower hinge, instead of the independent cleat h h, and that the latch p p may be arranged on theinside of the Window in lieu of being placed in a mortise in the same. It will also be seen that the sliding rod may be arranged in its mortise, so as to turn or swivel laterally as well as move forward and back, being connected to the arm on the blind by a hinge-joint or otherwise; but this arrangement we deem to be substantially the same in principle as that we have described above.

Another method of fastening the blinds when opened or closed has occured to us as a modification of that above explained. -It vis simply to form a proper notch on the under side of the sliding rod m m near the knob n', which notch should be so arranged as to hook over a stationary catch and hold the blind as desired.

Having thus described our new contri Vance for opening and closing blinds we shall state our claims as follows:

Vhat We claim as our invention, and desire to have secured to ns by Letters Patent,

The apparatus hereinabove described for opening and closing blinds from the interior of the house Without openingr ythe saslies, said apparatus consisting of a horizontal slotted arm fastened to and projecting from the blind, as described, and a lever-arm cast on and projecting at right angles from asliding and-- turning rod passed through the Window-frame, as described.
