.BLlND-SLAT CHECK.

SPECIFICATION forming part of Letters Patent No. 319,620, dated June 9, 1.885..

Application filed February 26, 1885.

To all whom it may concern.-

Be it known that I, JOHN RAOEY, of Quebec, Canada, have invented a new and Improved Blind-Slat Check, of which the following is a full, clear, and exact description.

The object of my invention is to provide a simple, inexpensive, and efficient devicefor locking blind -slats partly or fully open or closed.

The invention consists in particular constructions and combinations of parts of the slat-check devices, including a plate pivoted to the lower blind-rail and adapted to engage the lower slat and the slat-connecting bar, and also a springcatoh fixed to the lower slat, for holding the slats in the various positions,all as hereinafter fully described and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures. Figure 1 is an inside face view of the lower portion of a Window-blind with my improved slat-check applied and adjusted for holding the slats fully open. Fig. 2 is a vertical sectional elevation taken on the line mm, Fig. 1. Fig. 3 is an inside face View of the blind with the check adjusted for holding the slats halfopen. Fig. 4 is a vertical sectional elevation taken on the line yy, Fig. 3. Fig. 5 is an inside face view of the blind with the check adjusted for holding the slats closed, and Fig. 6 is avertical sectional elevation taken on the line 2 2, Fig. 5.

The letter A indicates the lower portion of an ordinary window-blind having the lower rail, (4, and stilesb 1), between which latter the blind-slats B are pivoted in the ordinary manner, and the slats are attached by staples 0, as usualwith the connecting or operating bar 0.

I show but two of the blind-slats B, in order to show the slateheck devices in larger scale to better advantage.

The slate-heck consists, mainly, of a plate, D, of metal or wood, made with one long fiat edge, d, and by preference an opposite-curved edge, (1, and also with a projecting lip or catch, d", and pivoted by a pin or screw, E, to the blind-rail to below the end of the slat-connccting bar 0.

(ModoL) To the outer face of the lower blind-slat B is fixed at one end the elastic or spring wirecatch F,which extends toward the bar 0, and is bent in a loop, f, at the free end, which loop passes through or enters a slot in the slat.

The operation is as follows: Vhen the slateheck is not in use, the plate D will be set with its edge (I uppermost and in line with the top edge of the blind-rail a, and its edge 01 will stop against a pin, G, set in the rail a, to hold it in this position and as indicated in dotted lines in Fig. 3, which will allow the slats to be moved freely by their connectingrod G.

Should it be desired to hold the slats B halfopen,to admit light and secure ventilation,the plate D will be swung up from the position shown in dotted lines, Fig. 3, to the position shown in full lines in Figs. 3 and 4., and so that its end at (1" will stand between thelower slat B and the connecting rod (l, and the slats cannot be moved either way from the outside. and as in this position the upper and lower edges of adjacent slats will allow no opening between them on a horizontal line privacy is secured when light and air are admitted through the half-open slats.

When the slats are to be held fully open,the plate D will be moved over to the position indicated in dotted lines in Fig. 1., either by swinging it between thelower slat B and bar 0, or beneath the end of the bar (3 when the slats are closed, the pin-stop H being set in rail or, to limit the down swing of the plate, as indicated in dotted lines in Fig. 1., and when the slats are fully opened the spring F will be pressed down, so that the lip d" of the plate D may be swung over into the loop or eyef of the spring to lock the slats '13 fully open, as will be understood from Figs. 1 and 2 of the drawings.

When the slats B are to be held closed, the end (I of plate D will be swung up under the end of the connecting-rod O, as will be understood from Figs. 5 and 6 of the drawings, and the slats will be locked together, so as to be quite as rigid as a solid panel to the blind.

The stop-pins G H are not essential to t successful working of the slatcheck devices,

as the pivot-screw E will hold the plate D at rest against the face of the rail until it is pur- IOO posely shifted to lock the slats in half-open,

- fully open, and closed positions; but the use of the stop-pins G His desirable for positioning the plate D, as above described.

5 It is evident that the precise marginal contour of the plate D shown and above described is not necessary, the essential features as toits shape being the end portion 6?, adapted to hold the blinds half-open and closed, and

I0 the locking-lip d",to serve,with the catch F,in

holding the blinds fully open.

My improved blind-slat-check devices are applicable alike to either inside or outside blinds, as will readily be understood.

15 Having thus described my invention,Iclaim as new and desire to secure by Letters Patent 1. The combination, with the lower rail, 0;,

and lower slat, b, of a blind, of the plate D, pivoted to. rail a, and provided with a lip, d",

and the spring-catch F, having loop f, and se- 2o cured to the lower slat, substantially as herein set forth.

2. The combination, with the rail a, slat B, spring F, and plate D, of the stops G H, substantially as herein set forth. 25

3. As an improved article of manufacture, the slat-check plate D, made with a lockinglip, d", and end portion or shoulder d substantially as herein set forth.
