BLIND-STOP.

SPECIFICATION forming part of Letters Patent No. 448,517, dated March 17,1891.

Application filed June 9, 1890. Serial No. 354,838. (No model.) I

To all whom it may concern.-

Be it known that I, THEODORE GoHLKE, of St. Louis, Missouri, have made a new and useful Improvement in Blind-Slat Fasteners, of

which the following is a full, clear, and exact description.

The improvement relates to that class of fasteners which are applied to the stick or rod which is employed in operating the slats ot' a Venetian blind; and it consists in the special construction whereby the stickor rod can be adjusted vertically and locked at any desired point of adj ustnient, substantially as is hereinafter set forth and claimed, aided by the annexed drawings, making part of this specification, in which- Figure 1 is an elevation showing the improved fastener in position. Only the lower portion of the blind is shown. Fig. 2 is a vertical section on the line 2 2 of Fig. 1; Fig. 3, an elevation of the case in which the bolt of the fastener works; Fig. 4, an elevation, partly in section, of the fastener-bolt, including the parts therewith moving as the bolt is raised and lowered in its case; and Fig. 5, a cross-section on the line 6 6 of Fig. 1.

The views are not all upon the same scale.

The same letters of reference denote the same parts.

The blind is of the usual construction, saving as it may be supplemented by the improvement under consideration.

The blind-slats are represented at B 13, and 0 represents the rod for operating the slats.

The-improved fastener is applied to the lower rail a of the blind. Its component parts are substantially as follows: the slotted tubularcase D, which by any suitable means such as the flanges cl and the screws d i's fastened totheblind-rail a, and the bolt E, which works longitudinally in the case D, and at its inner end a is provided with a handle e, which is journaled upon the bolt to be turned horizontally thereon, as indicated, and at its outer end 6 is provided with an elongated eye a, to which is joined a socket a The rod 0 at its lower end is secured in the socket 0, so that by working the bolt E in its case the blind-slats can be turned upon their journals and adjusted as desired. The bolt E is operated by means of its handle 0', to which end the handle is turned upon the bolt to bring the handle-neck 6 into line with the longitudinal slot (1 in the case when the bolt is moved inward or outward in the case, according to the direction in which it is desired to move the blind-slats, and after the bolts and slats have been adjusted as desired the handle 6' is turned upon the bolt to cause its neck toenter that one of the series of. slots d which extends laterally in the shell of the case to the right and left of the longitudinal slot therein and connects therewith, substantially as shown. As the bolt E is thus moved its eye remains at right angles to the blind A, as shown in Figs. 1 and 2, and for this purpose the case D is provided with a pin (1*, Fig. 5, which engages in a groove c, extending longitudinally in the bolt. Provision is thus made for the outward and inward movement of the rod O as it. is raised and lowered. The rail to has a recess to admit the eye c when the bolt E is drawn downward.

I claim 1. In combination with the blind having the journaled slats and rod, the herein-described fastener, the same consisting of the case I), having the longitudinal and lateral slots,the bolt E, having the journaled handle and the elongated eye, and the socket jointed to said eye, as set forth.

2. The combination of the case having the longitudinal and lateral slots, the bolt having the handle journaled thereon at or toward its a lower end and having the elongated eye at its upper end, and the rod-socket, substantially as described.
