T. OREGAN. Blind-Slat Retainer.

TIMOTHY CREGAN, OF WILLIMANTIC, CONNECTICUT.
IMPROVEMENT IN BLIND-SLAT RETAINERS.
Specification forming part of Letters Patent No. 208,691, dated October ti. 1879; application filed July 29, 1979.
To all whom 'it may concern:
Be it known that I, TIMOTHY OREGAN, of Villimantic, in the county ot Windham and State of Connecticut, have invented certain new and useful Improvements pertaining to a Blind-Slat Retainer, of which the following is a specication, reference being had to the accompanying drawings, wherein- Figure 1 is a front view. Fig. 2 is a side view of the blindan edge view.
The invention is an improvement in that class of devices used to retain blind-slats in any desired position of adjustment; and consists in a construction of parts whereby simplicity, cheapness, and efficiency are attained.
It has been found necessary heretofore, in devices of this kind, where the slat-rod and blind-frame were directly connected, that some kind of a joint should be made use of in the connecting and adjusting device to compensate for the rotary movement of the slats. This was a source of additional cost, and ren dered the device more or less complicated and cumbersome.
In my device I avoid all of these undesirable features by omitting this joint and substitutin g an inandout right-angle movement. This movement has all the ease of manipulation of the old devices and the additional advantage of great cheapness and simplicity.
The letter a denotes the blind-frame; b, the pivoted and partially-rotatin g slats, and c the slat-rod, loosely jointed to all the slats. To this slat-rod are attached two or more eyes, d, in which lies the ratch-bar e, in such shape that the eyes have longitudinal play on the ratch-bar. This ratch-bar turns an elbow or angle at the bottom, and runs into an orice, f, made in the frame a, in such shape that theI ratch-bar can play back and forth toward and from the face of the blind.
As a modification, the horizontal part of the ratch-bar may run through eyes attached to the top of the bottom bar of the blind-frame. The ratch-bar bears a ratch, e', 011 the side, and the slat-rod bears on the side a springpawl, g, taking into the ratch, and thereby holding the rod and the slats in the desired position of adjustment. The position of the spring-pawl attains and gives a great convenience in manipulation. By grasping the slatrod and springpawl between the thumb and rst iin ger, the hold of the spring-pawl on the ratch is broken, and immediate] y, and without shifting the grasp, the slats can be manipulated to the desired adjustment; and on letting' go, the spring-paul flies to engagement with the ratch, and holds the slats to position.
I claim as my invention- The frame a, bearing the oricef, the rotary slats b, the Slat-rod c, bearing on its side the eyes cl and the spring-pawl g, and the ratch,A bar e, sliding in the eyes d, and its elbowed foot sliding in the orifice j', all combined as described, for the purpose set forth.
TIMOTHY OREGAN.
