ANTIRATTLING DEVICE Specification of Letters Patent.

FOR WINDOW-BLINDS.

Patented Nov. 16, 1915.

Application filed September 11, 1915. Serial No. 50,262.

To all whom it may concern I Be it known that I, AUoUs'r P. ANDERSON, a citizen of the United States, residing at Newport, in the county of Newport and State of Rhode Island, have invented certain new and useful Improvements in Antirattling Devices for lVindow-Blinds, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to an improved anti-rattling device for window blinds and hasfor its primary object to provide a simple, inexpensive and very effective device, whereby the blind may be securely held in its' open position against rattling or banging against the wall of the building.

It is a more particular object of the invention to provide a device for the above purpose constructed from a single piece of resilient metal adapted to be securely fixed intermediate of its ends to the building wall and having curved spring terminals of relatively different lengths, one of which is adapted to bear against theframe of the blind and the other against one of the pivoted slats of the blind or shutter, whereby the blind will be held against movement relative to the Wall and the shutter slats-will also be held against movement in the blind.

With the above and other objects in view, my invention consists in the novel features of construction, combination, and arrange ment ofparts to be hereinafter more fully described, claimed, and illustrated in the ac companying drawing, in which,

Figure 1 is a vertical sectional view through a blind, illustrating the application of the preferred embodiment of my invention; Fig. 2 is a section taken on the line 2-2, of Fig. 1; Fig. 8 is a perspective view of the device detached from the building wall.

Referring in detail to the drawing, 5 designates the window blind which is mounted at one of its vertical edges upon hinges indicated at 6 for swinging movement. This blind is equipped with the usual ventilating shutter embodying a series of spaced pivotedly mounted slats 7 which are loosely connected at their medial portions by an operating bar or rod 8. In the bottom portion of the blind frame, adjacent its free or vertical edge, a hook 9 is pivotally mounted in any preferred manner and the bill of this hook is adapted for engagement with an eye 10 projecting from the face of the building wall.

My improved blind holding device consists of a single length of resilient steel 11 having a straight medial portion provided with spaced openings 12 for the reception of suitable fastening screws 13 whereby the device may be securely fixed upon the face of the building wall,'as shown in Fig. 1. The holding device is preferably located on the wall at a point which. will be substantially mid-way between the opposite vertical edges of the blind when the same is open and adjacent to the lower end of the blind. The length of resilient steel is of uniform thickness throughout and from the straight medial portion thereof, the steel plate is formed into an upper reversely curved spring arm 14, said arm being provided with a comparatively wide downwardly curved section 15 and a relatively small reversely curved terminal bend 16. At the other end of the resilient steel plate, the same is formed into a lower curved spring arm 17 which is considerably shorter than the upper arm 14 and offers greater resistance to a laterally applied pressure. This arm terminates in a substantially circularly curved bend or loop 18. The resilient steel spring plate also preferably tapers in width longitudinally from its intermediate portion to its extremities.

Upon referring to Fig. 1 of the drawings, the operation of the device in practical use will be readily understood. When the blind is swung outwardly to its open position so that the hook 9 will engage in the eye 10, the lower horizontal frame bar of the blind will bear against the terminal loop 18 of the lower relatively short spring arm 17 with sufiicient pressure to place said springnrm under tension so that the same will exert an outward force against the blind and thus hold the bill of the hook 9 tightly in engagement with the medial portion of the metal eye 10. The terminal loop 10 of the relatively long upper spring arm 14 will be engaged by the lower shutter slat 7, below the plane of its pivotal axis and will also exert a pressure thereon so that the series of slats will be held against movement relative to the blind frame. In this manner, the blind and its shutter are securely held, when in open position, against movement with respect to the wall of the building, so that rattling or slamming of the same and the resultant objectionable noise, is obviated. 1

From the foregoing description taken in connection with the accompanying drawing, it will be seen that I have produced a simple, reliable and highly convenient blind holding device, which can be readily applied to the building walland does not require any structural alterations whatever in the blind. The steel springs can be conveniently cut out of a metal sheet by means of a suitable die, sothat the device can be very inexpensively manufactured.

\VhileI have shown and described what I believe to be the preferred embodiment of the device, it is to be understood that the same is susceptible of considerable modi I fication therein and I therefore reserve the privilege of adopting all such legitlmate changes as may be fairly embodied within the spirit and scope of the invention, as claimed.

Having thus described this invention, What I desire to claim as new and secure by Letters Patent, is z 1. A blind holding device comprising a single element adapted to be fixed to a building wall and having means to engage the blind and hold the same against swinging movement when in its open position, and additional means to engage one of the shutter slats of the blind and hold the shutter against movement with respect to the blind frame; i

2. .Ablind holder comprising a single resilient metal plate adapted to be fixed at its medial portion to a building'wall, and having spaced spring arms of relatively different lengths, one of said arms being adapted to engage the blind when the same is 1n its open position and hold said blind against swinging movement and the other of said arms having bearing engagement with one of the shutter slats to hold the shutter against movement with relation to I the blind frame.

3. The combination with a window blind provided with a slat shutter, and means for ing upon one of the shutter slats to holdthe shutter against movement with respect to the blind frame. i

In testimony whereof I hereunto affix vmy signature in the presence of two witnesses.
