@Minstens getraut @ffice MAX ADLER l AND LOUIS KN ELL, OF BUFFALO, NEW YORK. Letters Patent No. 61,035, dated January B, 1867.
To ALL .wHoM IT MAY. conchas;v
Be if, .known that we, MAX ADLER and LoU'Is KNELL, both of the city of Buialo, in the county of Erie, and State of New York, have invented a certain new and useful improvementfin Hinge and Sash-Fastener Combined; @and we do hereby declare that the following is a full and. exact description thereof, reference being had to the accompanying drawings making part ot' this specification.
' Figure 1 is a horizontal section of one side of a Window frame, with theblind in a closed position, and a plan View of our improvement applied thereto.
Figure 2 is Va similar view, with the blind shown as being open.
Figure 3, an elevation of the hinge and fastening detached, with the upper wing raised from its connection with the lower wing and lever. Y
Figure 4, a diagram, representing thedog and catch for holding the lever and preventing it from turning.
Like letters of reference indicate corresponding parts in all thegures.
VIt is the object of our invention to combine a hinge for window blinds with a device for operating and fastening the same, in such a manner that the blind may be readilyopened and shut from the inside, and secuned rmly in either position and it consists inthe following-described device in combination with the. lower hinge ofthe blind. i
As 4represented in the drawings, A and B indicate, respectively, the ordinary window frame and blind. The hinge proper is formed in two parts or wings, the lower wing a being made with right-angular plates, iitting around the corners and-fastened to thefrarne A; and the upper one, 6, is secured to the window blind B in the ordinary manner. These wings are connected by means of a spindle, c, extending downward from 'the upper wing, and resting in a corresponding socket in the lower one, indicated by dotted lines, fig. 3. The
upper wing attached to the blind is made with two hooked points or beaks, d d, whose extremities approach cach other, leaving but a small space between them, as shown. Within these points is an'open space, the
surrounding metal being formed with'a bevelled concave, e, in the peculiar manner represented. From a hand-A knob, g, on the interior of the Wall, a spindle passes through the window frame, having its outer extremity, f, bent upward so as to enter the open space inside of the bealis d d, in a position to engage with the concave sides of e, when the knob gis turned for opening and closing the shutter; or, when at rest, to be in the space directly between the opposing points i d, and form a lockte prevent the same from being moved. When the blind is closed the outer extremity of the lever frests between the points of the beaks d d, (as shown in iig. 1.) By turning'the handle g the lever is raised, and presses against the bevelled side of the concave e, at one side of the centre of motion, causing it to revolve on the axial pin e and open the blind, the end of the leverf sliding around within the bevelled concave until it again drops between the points d (Z, in a transverse position, (as shown in tig. 2,) but is prevented from dropping below these points, when in either position, by a stop, z', secured to the spindle, which strikes against the top of wing a, or by any other suitable means oi' arresting its motion. By reversing the motion the blind may be closed in the same manner. When the blind is either closed or open, the lever f rests between the points d d, and serves as a fastening to prevent the wing b from turning, and consequently thc blind is secured in place. The lever lis provided with a ratchet-wheel, h, and the wheel is also provided with a dog or catch, lc, suspended from above on the inside of the windpw frame, as shown most clearly in iig. 4. When the lever is rturned to the positiondesired, thev dog k engages with the rag-wheel, and this wheel'being secured to the lever f, it is held rmly and prevented from turning in either direction until the dog or ,catch is disconnected therefrom; and, consequentlyhe blind will be held securely when either closed or open, or in an intermediate position, and cannot then be turned from the outside. When it is desired' to open or close the window blind, it is only necessary'to raise the catch c and turn the handle g inthe required direction, when it is easily vswung around to any position desired, and at the same time is securely fastened without the troublesome necessity of opening the window in inclement weather to unfasten or turn the same. But one of these devices for each blind is required, which should properly be placed at the bottom, for convenience in handling, and the knob g may be made of any suitable form or shape to enable the lever-spindle to bel-conveniently turned by it, and admits of being made a highly ornamental appendage to the window.
While performingftheir proper function of operating the blinds," the pair willvat the same time serve the double purpose of curtain knobs.
What we claim as our invention, and desire te secin'e by Letters Patent, is-A In a hinge and blindfastener combined, the points or beakis d d, bevelled cncavee, bent lever j', kob g, and the part a of the hinge, in combination with lthe ratchet-Wheel h, and dog k, substantially as set -forth.
In Witnesswhereof we have hereunto signed our names in the presence of two subscribing witnesses.
Witnesses: J. A. DAVIS, J. FRASER.
