MEANS FOR USTING TILATING-CLOSURES.

Application filed November 27, 1914. Serial N 0. 874,188.

To all whom it may concern:

Be it known that I, EVAN LLEWE LYN, a subject of the King of Great Britain and Ireland, and residing at Tanybryn, Ystrad, ithondda, in the county of Glamorgan, Wales, have invented certain new and useful improved Means for Adjusting Ventilating- Closures, of which the following is a specification.

This invention relates to adjusting means for ventilating closures such for example, as skylights, fanlights, ventilators, and windows of the type comprising an adjustment bar secured to the movable member of the window or the like, and a spring-controlled detent carried by the fixed member and adapted to engage one or the other of a series of apertures in the adjustment bar.

The object of the invention is to devise such improvements in arrangements of the above character as will enable the same to be employed with any type of window or like closure, wl'iether the same is arranged vertically, horizontally or inclined and whether the closing member is to move inward or outward, a further advantage of the invention being that the device is capable of being readily manipulated however inaccessible may be the window or the like to which it is fitted.

lVith this end in view the invention con sists in the novel combinations hereinafter more particularly referred to.

The accompanying drawings illustrate one mode of carrying out the invention':

Figures 1 and 2 are a side sectional eleva-- tion and a front elevation more or less diagrammatic showing the invention applied to a ventilator or fanlight; I

Fig. 3 is an enlarged view of a detail shown in Fig. 2.

In carrying my invention into effect in one convenient manner I pivotally secure to the free edge of the fanlight or the like q which is hinged to the structure Z) along its other edge as at c in the usual manner a bar or like member (Z which may be straight or curved as desired and which may be formed from metal or other suitable material. The bar or the like member (Z is adapted to protrude through a slot in a guide block 6 iounted upon the framework of the fanlight or the like, which guide is adapted to oscillate (as, for example, by being pivotally mounted in brackets f fixed to the framework) so as to accommodate itself to the Specification of Letters Patent.

movements of the bar (Z, this being necessary by reason of the fact that the fanlight rotates' about an axis coinciding with the center line of the hinge 0. The bar or like member (Z is slotted or notched at intervals along its length or provided with apertures with which a springcontrolled catch or detent Z mounted upon the guide 6 is normally adapted to engage, the number of slots, openings or notches being regulated to suit the extent of adjustment or regulation that is required for the fanlight or the like.

In one convenient construction the detent comprises a projection h (Fig. 3) carried by a double-ended lever 71 pivoted. upon the guide 6 and controlled by a spring is, the arrangement being such that the projection 72, passes through an aperture in the part of the guide 6 adjacent to the member (Z. The free end of the lever 2' is connected to an operating cord or like flexible member 0 so that the projection k may be raised by pulling upon the cord when it is desired to alter the adjustment of the fanlight, and the adjustment may be efl'ected in one direction or the other by pulling upon a cord or like flexible operating member p. having its ends attached respectively to the two ends of the adjustment bar 03 and being adapted to pass over two pulleys or like anti-friction members n mounted in the guide block 6 preferably immediately below the slot therein through which the adjustment bar cl passes;

A pulley m is also provided for the cord or the like member 0 for the lever 2'. The respective cords are of such a length that they may be within easy reach of the operator to facilitate the manipulation of the device however inaccessible the device itself may be.

Having now described my invention what I claim as new and desire to secure by Letters Patent is Adjusting means for ventilating closures comprising a guide block pivoted to the fixed portion of the Window or the like and having a slot therethrough, an adjustment bar pivoted to the movable member of the window or the like and, having a plurality of apertures therein, the adjustment bar passing through the slot in said block, a springcontrolled detent comprising a double-ended lever pivoted upon said block and having a projection on one endcthereo'f adapted to pass through an aperture in said block, and into one or the other of the apertures in said adjustment bar, a flexible operating member Liand below the slot in said guide block for attached to each end of said adjustment bar, In testimony whereof I have signed my a separate flexible operating member attached name to this specification in the presence of 10 to oneend of said double-ended lever, two two subscribing witnesses.

anti-friction members arranged centrally of EVAN LLEYWELLYN.
