SPECIFICATION forming part. of Letters Patent No. 316,529, dated April 28, 1885.

Application filed November 26, 1883. (Model) To aZZ whom it may concern Beit known that I, LI'JON O. DION, of N atick, in the county of Middlesex and State of Massachusetts, have invented a certain new and useful Device for Opening and Closing Blinds and Shutters, of which the following, taken in connection with the accompanying drawings, is a specification.

My invention relates to devices for operating shutters or blinds from the interior of the house to which they are attached; and it consists in certain novel features and arrangements of parts, which will be readily understood by reference to the description of the drawings and the claims to be hereinafter given.

In the drawings, Figure 1 represents a perspective view of a window the blinds of which are provided with and operated by my improved device. Fig. 2 represents an enlarged side elevation of my improved device, the different parts of which being shown in the positions they occupy when the blinds-are closed. Fig. 3 represents afront elevation of the same. Fig. 4 represents a side elevation of the same with the parts thereof in the positions they occupy when the blind is opened. Fig. 5 represents a partial sectional elevation on line 00 w on Fig. 2. Fig. 6 represents a central longitudinal section of the rotary lifter. Fig. 7 represents a sectional elevation of the blindfastener, the cutting-plane being transverse to the window-sill; and Figs. 8 and 9 represent, respectively, a side elevation and a plan of the pintle, which is attached to the blind.

A is a window-frame of the usual construction, B is the sill thereof, and O C are blinds secured thereto by the hinges a a. Each blind is provided on its lower end with a suitable fastening device for retaining the blind either in an open or closed position.

The device shown in the drawings consists of avertically-movinglatch, b, secured by one end to the blind near its pivotal edge, while its opposite end extends through the stapleguide a, and is retained in the bottom thereof by virtue of its own tension. This latch 22, when the blinds are closed, engages with the catch d and retains the blinds in that position, while it effects the same object when open by engaging with the catch 6.

A little above the lower hinges a a suitable holes are bored through the window-frame, to each of which holes is fitted a metal tube, D, in which is mounted the shaft E, to the inder end of whichi. 6., that end which enters the interior of the house-is firmly secured the crank-handle F. Near the outer end of the shaft E the rotary lifter G is firmly secured thereto, so as to revolve therewith. The extreme outer end of the shaft E consists of an enlarged hub, f, to which is firmly secured the spiral spring H, the opposite end of which is secured to the vertical hub g of the removable pintle I, mounted in a suitable bearing in the ear J of the metallic bracket K, firmly secured by screws or otherwiseto the blind O, the said pintle I being provided with an ear, m, in which is formed an angular notchun, to fit the corner of the bracket K, as shown in Figs. 3, 8, and 9.

WVhen the reduced end of the pintle I is in the bearing in the ear J, and the corner of the bracket K is within the notch n, and the spring H is holding the said pintlel in this position, the said pintle is as rigid with the bracket K as if it formed an integral part thereof, and therefore the blind C may be readily moved about its hinges by rotating the pintlel.

' The rotarylifter Gis made of such a diameter that the toe h, mounted on its outer edge parallel to its axis, projects beneath the shoulder '5 of the bracket K, the blind being pro vided with a suitable cavity, It, to accommodate such rotation of the toe h. The bracket jecting arm Z, by which the blind may be lifted when the said blind is in an open position.

The operation of my invention is as follows: The different parts of my improved device being in their normal positions, as shown in Figs. 1, 2, 3, 5, and 7 of the drawings, if the blinds are desired to be opened, the handleF is moved iuthe directionof the arrow, Fig. 1, thereby rotating the lifter G and bringing the toe h thereof in conjunction with the shoulder t upon the blind, when, if the lifter G continues to be rotated, the blind G will be lifted upon its hinges a a a sufficient distance to disengage the latch 72 from the catch d. While the blind O is being thus lifted and the shaftE rotated, the vertical pintle I is prevented from 5 K has extended from its front surface the prorevolving until the latch b is released from the catch'd on account of the engagement of the notch n of the ear m thereof with the cornerofthebracketKupon theblind O,and,there- 5 fore, as one end of the spring is being rotated with the shank E while the other is securely held 'in' a fixed position, an extra torsional strain is given to the spring H, which, when the blind G has been lifted so as to disengage the latch b from the catch d, causes the blind to swing outwardly. The continued rotation of the handle F, shaft E, and hub f causes a torsional strain to be transmitted through the spring H to the pintle I, which. is thereby r 5 cause to rotate in its bearing, and by virtue of the notch n-of the ear m, acting upon the corner of the blind O, the said blind is also caused to rotate until the latch b engages with the catch e, when the blind will be retained in an open position.

repeated, with the exception that the toe it acts upon the projection Zto lift the blind, instead of acting upon the shoulder i.

If at any time it is desirable to remove the blind, it can readily be accomplished by simply go removing the pintle Ifrom its bearing, which will sever all connections between that part of the device which is, attached to the frame and that which is applied to the blind, so that the blind may be lifted from its hinges.

It is obvious that the connections may be as readily made again by simply placing the notched end of the ear m against the corner of the bracket K and inserting the reduced end of said pintle I in its bearing.

5 with any other means for rotating the blindas, for instance, a pair of bevel-gears or a balland-socket joint. Y

. To operate the shutters from the interior of the hous'ein stormy weather without the necessity of opening the window has long been deemed advantageous, and therefore many attempts have been made to accomplish this object, the results of which have failed to come into general use either on account of their liability of getting broken or otherwiseinoperative, or on account of their complexity and cost.

To obviate these difficulties is'the object of this invention. 1

One of the greatestdisadvantages-to be It is obvious that instead of a spiral spring found with devices for this purpose heretofore constructed is that. their only point of fasteningis on the hinged side of the blind and generally in a line with the axis of rotation of the blind, so that the wind in rough weather is liable to get so great a leverage upon the blind as to tear it from its points of attachment; but in the improved device herein described this disadvantage is entirely obviated, as each blind has a fastening device secured thereto at some little distance from the axis of rotation of the blind, the said fastening device being operated, as has already been described, from the interior of the house. I am aware that a coiled spring has been heretofore used for transmitting power.

What I claim as new, and desire to secure by Letters Patent of the United States, is=- 1. A device for operating blinds or shutters, consisting of a shaft adapted to pass horizontally from the exterior to the interior of the window-frame and provided on its inner end with means for rotating it, a support or car adapted to be attached to the blind, and flexible coupling composed of a spiral spring rigidly secured at one end tothe shaft and at the other end to the ear, as set forth.

2. In a blind or shutter operating device, the combination of the crank-shaft E, the rotary lifter G, the shoulder or arm 1', and a means for connecting said shaft E with a vertical pintle secured to the blind G and adapted to transmit motion from the said shafttd the said pintle and through it to theblind, substantially as described.

3. In a blind or shutter operating device,

the combination of the crankshaft E, the r0 Y tary lifter G, the shoulder or arm I, and a means for connecting said shaft E with a vertical pintle secured to the blind O and adaptrco ed to transmit motion from the said shaft to the said pintle and through it to the blind, substantially as described.

4.- In combination with a blind or shutter pivoted by one of its vertical edges, the crankshaft E, the revolving lifter G, the bracket K,- with the shoulders or arms iand Z, firmly secured to the pivotal edge of the blind or shutter, a flexible or universal joint connecting the shaft E with the bracket K, the latch b,

and catch 01 or c, all arranged and adapted to 1 operate substantially as described.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 23d day of N ovem-'
