' Applicatio'n filed .Tuly 28,

My invention has particular relation to operating means for operating the usual. opposite shutters of skylights althoug'hnot l1mited to this use alone. I

The main object .of the invention resides the provision of slmple and effective means whereby. either of two reciprocable members may be positioned to either end of its move ment while the other is ateitherend of-its movement through the medium of a single f operating member. As applied to theopera tion of opposite shutters of askylight both shutters may. be .fullyopened or closed or either maybe fully opened or closedw thout necessitating-the otherbeing in any particu z ,lar posit-ionsueh as closed position, thus providing a universal controlof the opposite shutters through the medium .of a single op erating member, whereby --where distant op eration is necessary or convenient as 1s usual train of distant control mechanism-is neces; sary. u t if .With th s ob ect 1n,v1ew my lnvent on con- Pa b other objects hereinafter-v appearing are ef fected. allas fully describedwith reference, to the accompanying drawings and more particularly pointed out in the. claims. in the saiddrawings my lllVGntlOIlfOI operating theoppositeshut ters of the skylight.

A. pair of links 21 arepivotally secured at their opposite ends to the lower endsof respective arms. 18 and toirespective links 5 whereby res ciprocable movement of the'arms williopen and close respective sets of, shutters4, ;and v .the brackets 17 are provided with opposite stops22-which limit the opposite, i. e,- shut- 1 ter. opening and closing, movements of respe'c tiv'e arms 18. ,The arms 18'ar'econnected' to :IGSPGOUVG ad acent crank pins 16;by. longhthereof, a cylindrical block 27 disposed within the portion 24for longitudinal sliding movement, and two coiled compression springs 28 disposed within the portion 24 at respective ends of the block 27 and respectively abutting the head 25 and plug 26 and abutting the block whereby to resiliently maintain the block in its normalposition at an intermediate point in its movement within the portion 24. See Fig. 4. The block 27 is pivotally secured'to the res )ective arm 18 by a headed stud 29 passing t rough dim metrically-opposite longitudinally extending slots 31 in the tubular portion 24 and a diametrical bore in the block 27 for pivotal movement therein and screwthreaded into the respective arm 18.

The arms 18 are moved between the stops 22 by angular movement of the respective gears 14 by means of the crank pins 16 and connecting rods 23 whereby the respective shutters are opened and closed. The throws of the crank pins 16- are excessive so that the arms 18 engage "the stops 22 at both ends of I their movements before the crank "pins reach the linesintercepting the axes ofrespective gears and the axes of respective studs 29. In this case the arms 18 engage respective stops when there is still 15 of angular dis tance between the-res tive crank insand the respective lines. he springs 2 permitting theblock'27 to move in the tubular portion 27 of the connecting rods 23 provide for the additionalmovement of the crank ins so that in the cycle of each gear lithe strokin of the respective arm 18 is alternated wit periods during which the arm 18 is held 7 against respective stops 22, during'one t er riod the arm 18 being held in closed sh position and during the other period it being held in open shutter position. As shown these periods each embrace 90 in the angular movement of respective gears 14.

As hereinbefore stated the crank pins 16 are sequentially timed at 90 so that the stroking riods of each arm occur during the periods when the other arm is held against one of the respective stops whereby either armmay be positioned to either end of its movement while the other arm is positioned at either end of its movement. The result is that either of the opposite sets of shutters maybe positioned in open or closed position while the other is positioned in either-open i new and desire to secure by Letters Patentthe following. I I V silientconnections coo or closed position thus providing universal adjustment thereof. rs 4: are as is obvious operated by the shaft 8 through the small gear 13 whereby the universal control of the shutters is provided through a single train of mechanism. It will be further observed that the mechanism permits of a plurality of shutter operating mechanisms being disposed at points along the operating shaft 8 and operated in unison therefrom.

While I have herein shown and particularly described the preferred embodiment of my invention I do not wish to be limited to the precise details of construction shown as changes may readily'he made without departing from the spirit ofmy invention, but having thus described my invention 1 claim as Claims: 1.
