T on whom it may concern:

Be it known that 1, JOHN J. QUAcKENBUsn, a citizen of the United-States, residing in Lakeview, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in'Blind-Fasteners and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled. in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

My invention relates to attachments for blinds or shutters having pivoted slats, and it has for its object to provide a device of the general nature above indicated designed especially for securing the slats of the blind or shutter either open or closed, and, as a further object, to provide a mechanism which shall comprise in a single organization means for both securing the slats of the blind or shutter and for securing closed the blind or shutter itself.

My invention will be found fully illustrated in the accompanying drawings, wherein- Figure 1 is an inside view of blinds or shutters provided with my attachment. Fig. 2 is a horizontal sectional view of the blinds, taken just above the attachment constituting my invention and showing the slats held closed. Fig. 3 is a view similar to Fig. 2, but'showing the slats held open; and Fig. 4 is a vertical sectional view taken just to the right of the attachment, as seen in Fig. 1.

On the meeting rail of each blind or shutter a, hinged in the easement b in the usual manner, is secured an elongated plate 0, 6X". tending vertically. At the outer edges of these plates are arranged leaves d, which are pivotally attached to the plates by means of hinges 8, whose pivots stand out from the plane of the plates in such manner that when the leaves are swung around on the hingesinto the position shown in Fig. 3 there is clearance between the adjacent edges of each plate and the leaf. The object of this will be explained later. Each leaf is bent longitudinally at right angles, so that when the leaf lies against the face of the meeting rail of the blind the bent-off portion f extends around the edge of the meeting rail and takes against several of the slats of the blind, it being understood that saidslats are at this time in their closed position. In order to lock theleaves in theposition just described as that where they hold the slats closed, I provide a latch or bar g, having its pivot on a stud h, which may project from one of the plates 0. The blinds being closed, this latch is held in the horizontal or securing position by means of a keeper 1', which may be conveniently attached to the other plate 0. I11 order to prevent the latch being manipulated from the outside of the blind, a guard j is pivoted on one of the plates 0 in such manner that when suspended vertically from its pivot 7.: it takes against the top of the latch to hold the same down in the keeper. Latch g is also adaptedto secure the slats in their open position. To this end, and as bestseen in Fig. 3 and alsoin dotted outlines in Fig. 4, latch g is made long enough so that it extends, when in the horizontal position, in the path of movement of two of the pivoted slats in each blind.

It is, furthermore, preferably made of such width as to just fill the space between two adj acent slats in each blind when the same are in their open position. (See Fig. 4:.) In order that the slats may assume the open position and yet be engaged by the latch, leaves dare swung back into the'position shown in Fig. 3, so that the clearance above referred to as then existing between the hinging edges of the leaves and the plates 0 will permit the latch to be turned into engagement with the slats, as best seen in Fig. 3. It will be understood that in looking the slats open, since the moving of the latch on its pivot to the horizontal position means that one end thereof must be depressed while the other is elevated, of course the two series of slats must be first arranged in relatively reverse positions, so that when or slotted member a receives a turn-button 0,

whose shank-p is threaded and screwed into a plate q, secured to the casement-sill a. By

adapted to engage said series of slats to maintain them closed, said member being pivoted on the blind and having its pivotal axis extending transversely of the slats, and means for locking said member in the securing position, substantially as described.

2. The combination of the blinds each havin g pivoted slats, of securing members adapted to engage said slats to maintain themclosed, each of said members being pivoted on a blind and having its pivotal axis extending transversely of the slats, and a common means for securing said members in the securing positions, substantially as described.

3. The combination of the blinds each having pivoted slats, of securing members adapted to engage said slats to maintain them closed, each of said members being pivoted on a blind and having its pivotal axis extending transversely of the slats, and a pivoted latch adapted to engage in common both of said members to lock the same in the securing positions, substantially as described.

4. The combination, with the blinds each having a series of pivoted slats, of a pivoted securing member adapted to engage each series of slats between two of the same to maintain said slats in the open position, substantially as described.

5. The combination of a casement, a blind arranged in said casement and having pivoted slats, and means for securing the slats in fixed relation to the blind and the blind in fixed relation to the easement, said means consisting of a relatively stationary member fixed to the blind, hinged members carried by said fixed member and one of Which is adapted to engage the slats, and means for interlocking the other hinged member with the easement, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this 20th day of February, 1903.

JOHN J. QUAOKEN BUSH.
