UNITED STATES PATENT FFICE.

GREGOR TRINKS, OF JERSEY CITY, NEW JERSEY.

WINDOW-CURTAIN SLIDE.

Specification of Letters Patent No. 28,922, dated June 26,1860.

To all whom it may concern.'

Be it known that I, GREGOR TRINKS, of Jersey City, Hudson county, State of New Jersey, have invented a new and useful Improvement in Window-Curtain Slides; and I do hereby declare that the following is a full and exact description thereof.

My invention consists in an improvement in construction and arrangement of the rack and spring catch connected with the sliding cord pulley of a window curtain slide or fastening.

The object of my invention is to effect the release of a curtain cord pulley slide, which has no other motion than a sliding motion, without making further tension upon the cord, and simply by pressing down the thumb piece of the spring catch.

To enable others skilled in the art to make and use my invention I will proceed to describe its construction and operation, reference being had to the annexed drawings, forming a part of this specification, in which- Figure l, is a front elevation of my improvement; Fig. 2, a side sectional elevation of the same; Fig. 3, a back elevation.

Similar letters of reference indicate the same parts.

A isthe frame of the slide; B, rack upon the edges of the same; C, thumb spring; C thumb piece on same; D, cross piece attached to spring; E, slide piece to which button G, and the spring C, are attached; E', rivet which unites spring C, and slide piece E; E, washer; F, friction wheel on the button Gr; H, slot in the frame A.

The frame A, of my improvement is made much in the usual manner, except that it is slotted through its central portions at H, and has rack teeth cut on its side parts as shown. The slide piece E is attached to the button G, by means of a rivet, the friction roller, F, over .which the window curtain cord passes, being secured on the rivet which unites the slide piece E and button G.

The spring C, is furnished at its lower part with a cross piece D, which fits the rack teeth of the frame. The spring is attached by a rivet E to the slide piece E, and moves with it. `When at rest the spring serves to hold the cross piece D, against the teeth of the rack, and thereby retains the slide piece E and its appurtenances, in a given position. A portion of the spring projects through the slot H, to a convenient point below the button G, and terminates in a suitable thumb piece C', the spring with its cross piece and thumb piece when connected with the cord pulley slide being, and performing the function of, a spring catch or latch. When it is desired to tighten the window cord, the finger is placed on C', and the spring C pressed inward, which carries back the cross piece D, clear of the rack teeth, and permits the required movement of the slide E, by means of the button G.

My improvement is one of great simplicity, efectiveness, and cheapness of construction. The objections to the common slides such as their liability to become worthless, after being a short time in use, and the danger of wounding the hand, by exposure to the unprotected edges and corners of the same, in the act of adjustment, are entirely obviated by my invention, and a safe, convenient and durable slide provided, at a reduced cost.

`What I claim as my invention and desire to secure by Letters Patent of the United States is- In connection with the slide of a sliding cord pulley, of a window curtain fastening the improved construction and arrangement of the spring latch and double rack substantially as described and substantially for the purposes hereinbefore set forth.

GREGOR TRINKS.
