WINDOW-BLIND HOLDER.

Specication of Letters Patent.

Application filed November 23, 1909.

Patented May 24, 1910.

Serial No. 529,560.

To alt whom it may concern:

Be it known that I, OLAUs THoMAsEN, a subject of the Kin@ of Norway, and a resident of the city o? New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved VVindow-Blind Holder, of which the following is a full, clear, and exact description.

My invention relates to mechanism for holding window blinds and analogous structures, my more particular purpose being to enable the operator to secure the blind rigidly in an infinite number of definite positions, so that the screening elect of the blind may be more readily controllable at will.

More particularly stated, I provide a jointed rod, made up of sections pivotally connected together, and secure the ends of this jointed rod permanently to the stationary window sill and the movable blind, and further provide means whereby the various sections of the ointed rod are normally movable relatively to each other but ma i at will be clamped in an innite number o definite positions.

Reference is to be had to the accompanying drawings forming a part of this speciication, in which similar characters of reference indicate corresponding parts in all the figures.

Figure. 1 is a fragmentary perspective of a window having storm blinds or shutters, each of which is provided with one of my improved window blind holders; Fig. 2 is a top view showing the same in plan, the walls being in section; Fig. 3 is a detail showing in perspective how the rod sections are connected together by a. joint which may be loosened or tightened at will; Fig. 4 is a detail showing part-ly in section and partly in elevation the mechanism appearing in Fig. 3; Fig. 5 is a fragmentary perspective showing a latch forming part of my device and carried by the shutter; Fig. 6 is a perspective showing another latch forming part of my device and mounted upon the window sill; and Fig. 7 is a view partly in section and partly in elevation, showing how the latch carried by the shutter engages with the latch mounted upon the window sill when the( shutter is closed.

The window sill is shown at 5 and the blinds or shutters at 6, the latter being hinged so as to swing relatively to the window sill. Mounted upon the window sill is a base 7 and extending upwardly from the latter is a stem 8 supporting a head 17, the upper surface of which is beveled. Integral with the stem 8 and parallel with the lower portion of the head 17 is a boss 18. A rod section 9 is provided at one of its ends with an eye 8a and this eye is, by aid of a pin 8", journaled between the head 17 and the boss 18, as will be understood from Fig. 7. The rod section 9 is also provided with an annular bearing plate 10, the latter having cllepressions 10, as will be understood from Another. rod section 11 is provided with an annular bearing plate 12 integral with it, this bearing plate being provided with lugs 13 which are adapted to enter the depressions 10a. A screw bolt 14 extends through the annular bearing plate 12, this screw bolt being provided with a reduced threaded portion 16 which extends through the bearing plate 10. A nut 16a is revolubly mounted upon the reduced threaded portion 16 and is normally tightened so as to secure the screw bolt 14 rigidly in relation to the annular bearing plate 10 A wing nut 15 is revolubly mounted upon the screw bolt 14 and may be turned so as to force the bearing plate 12 down against the bearing plate 10, thus causing the lugs 13 to enter the depressions 10at and thereby lock the rod sections 9, 11 firmly together. By turning the wing nut 15 so as to loosen it relatively to the bolt 14, the rod sections 9, 11 may be turned relatively to each other, so that the ointed rod, as a whole, is virtually bent to different angles, as will be understood from Fig. 2. A bracket 19 is mounted upon each blind or shutter 6. This bracket is provided with parallel walls 19a extending outwardly from it. The outer end of the rod 11 is provided with an eye 9al and. this eye is, by means of a pin 9b secured to two parallel, perforated flanges 19b integral with the bracket 19.

A bell crank lever 20 is pivotally mounted upon a pin 21 carried by the walls 19a and is provided with a hook portion 22 of the form shown in Fig. 7 The lever 20 is further provided with a thumb piece 20a to enable it to be readily rocked by hand upon the pivot 21. A leaf spring 23 is connected with the lever 2O and engages the bracket 19, as indicated in Fig. 7. The operator, by placing his thumb upon the thumb piece 20a and forcing the latter backward-that is, toward the shutter with which it is associated-causes the hook 22 to be raised. It will be seen, therefore, that the lever 20 carrying its hook 22 is a form of latch which is adapted to engage and disengage the head 17, the latter being a form of latch.

The operation of my device is as follows: The operator grasps the wing nut l5 and by turning it loosens it relatively to the screw bolt 14. He then grasps the blind and swings it into the position which he wishes it to occupy. I-Ie next tightens the wing nut 15. In swinging the blind he causes the lugs 13 which are of rotund conformity to glide out of the respective depressions l0a in which they have been, and to glide back into other depressions l()a than the ones which they left. When the wing nut is tightened, the rod sections 9, ll can not be moved relatively to each other, and consequently the blind must remain in the position in which it is thus located.

When the blind is closed as indicated at the right of Fig. 2, the latch carried by the blind engages with the stationary latch mounted upon the window sill, and the blind is thus locked in position independently of the clamping action of the wing nut 15. The action of each blind is for the most part independent of the action of the other. It will thus be seen that the operator may at will place either blind in any one of a large number of denite positions, and, further, that either blind may be closed and latched independently of the other. It will also be observed that if the blind at the right of Fig. 2 be first closed and latched, and then the blind at the left of said ligure be closed and latched, the blind last mentioned forms, to some extent, a lock for the other blind, as is usual in window constructions.

While I prefer to mount the base 7 upon the window sill, I do not limit myself thereby, because obviously it may be mounted upon any convenient part of the window frame or other stationary fixture.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

The combination of a stem provided with a head having a beveled upper surface, a jointed rod journaled to said head, a swing ing blind, a latch carried by said swinging blind, a bracket mounted upon said swinging blind and connected with said jointed rod, and a latch journaled upon said bracket and provided with a thumb piece whereby it may be actuated, said latch being further provided with a hook for engaging said beveled upper surface of said head.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
