i Application iiled Marh 1]., 1899. Serial No. 708,632. (No model.)

To all whom it may concern:

Be it known that I, GEORGE H. HAMALIAN, a citizen of the United States, residing in Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Window Shutters or' Blinds; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to makev and use the same, reference being had to theaccompanying'drawings, and to letters `of refer ence marked thereon, which form a part Vof this specification.

This invention relates particularly to blinds or shutters having movable slats; and the object ofthe invention is to provide'a blind or shutter of this kind with means for adjusting its slats to various positions, it being a further objectto so construct a blind or shutter provided with this adjusting means that simplicity, inexpensiveness, and facilityin operation will be attained.

,'The invention consists in a blind or shut ter provided with my improved Slat-adjusting means and in the combination and arrangement of the various parts, substantially as will be hereinafter pointed out and finally embodied in the clauses of the claim.

My invention is fully illustrated in the accompanying drawings, wherein- Figure lis a perspective view showinga blind or shutter mounted in position in a window-frame and provided with my improved Slat-adjusting means, certain parts being shown in section. Figg2 is a transverse sectional view taken on the line in Fig. 3. Fig. 3 is an enlarged view in elevation of a portion of the blindand my Slat-adjusting means, portions of the latter being broken away to clearly show certain details thereof. Fig. 4 is an inside viewot the casing of said Slat-adjusting means, showing certain of the parts of l said means operatively arranged therein; and Fig. 5 is a longitudinal sectional View of a modilied form of my improved slatadjusting means detached from the blind;

In said drawings, a designates the frame of a shutter or blind, in one of whose vertical or side rails b the slats c are pivotally supported and in the other of whose side or vertical rails in the side of said rail which is adjacent thel slats. rSaid recess e extendsapproximately as far asfrom the top to the bottom rail of the-blind or shutter frame. 1

` f designates a metallic three-walled casing which is substantially rectangularin crossf section and which' receives between its two side walls f f? the rail d,lbeing so disposed thereon as to cover the recessie in said rail. In order that the outer surfaces-of the side walls f f2 of the casing may beiiush with the corresponding faces of the rail, said side wallsjare set into grooves g, formed in the latter. 'The third wall h of the casing f is provided with av series of orifices h', which provide bearings for crank-shaped pins z', one

'of which projects from the adjacent end of' each slat. v

j is a reciprocating rod which is arranged in the recess c and which is provided With a series of holes j', each of which lreceives the free end of one of the crank-shaped pins fi. Said rod is provided with apin 7c, which projects toward the Wall h of the casing and abutsagainst the same, so as tojprevent an undue binding between the rod and the pins t'. There may be one or more of these pins la, as desired.

Z designates elongated bent springs which are secured in the recess between the rear Wall of the same and the rod, said .springs acting to firmly maintain the latter in its operative engagement with the crank-shaped pins 'L'.

m is an operating-lever for the reciprocating rod j.' Said lever vis pivoted near one of Yits ends on a pin or screw fn, that 4projects through the wall h ot' the casing and into the rail d, thereby serving the double function of a securing means for s'aid casing and a fulcrum for the lever. It will be obvious, of course, that the lever maybe fnlcrumd upon any other pin or screw, if desired. Said lever projects through and is movable-in alongitudinal opening o, formed in the inner side wall f2 of the casing, and it is provided with a longitudinal openingp, that receives a pin p', projecting from the reciprocating rod j.

q denotes a slide having an orifice q therein just large enough to admit the lever m, said slide being adapted as a closure for the longitudinal opening o in the wall f2 of the casing and being maintained in its operative position by virtue ofthe fact that it is set into an elongated recess g2, formed in the rail cl and communicating with the larger recess e therein.

In the modified form of my invention I" have provided means whereby the reciprocating rod, and consequently all the movable parts connected therewith, may be automatically locked in such a way that the slats'can only be operated from the inside of the blind. The device in this instance is substantially the same as that hereinbefore described, with the exception that instead of providing a lrea cess in the rail wherein the slide q moves and whereby it is maintained in its operative position-that is to say, against the'inner sur` face of the wall f2 of the casing-elongated bent springs s are secured in said casing to its side Wall f and bearat their free ends against the slide, said slide being provided with a knob or lug t, that is adapted to en-` gage either one of two or more `openings u. 'Fliese openings u taper toward the outersurface of thewall f2 of the casing, and the free end of the lug or knob is rounded.

o is screw which penetrates one of the side walls of the casing and projects into the rail d, so as to secure said casing in place.` I have only shown one of these screws, but` several may be used for this purpose.

It will be apparent that when it is desired to adj ust the slats at any desired angle it will only be necessary to move the lever m up or down about its fulcrum. Ii the device is provided with the locking means comprised in the modifiedform of my invention, it is only necessary to iirst press` inwardly.` the knob orlug t, so as to release the slide 'and permit the actuation of the lever. The openings u are tapered outwardly, and the lug or knob L' is rounded at its free end, of course, so as to facilitate the disengagement.

Having thus fully described myinvention, whatl claim as new, and desire to secure by Letters Patent, is

l. In a blind or shutter having pivoted slats,'a casing secured to one of the vertical rails of said blind, a reciprocating rod arranged in said easing and having an eccentric connection with each Slat, a suitably-fulcrumed actuating-lever for said rod, said casing havingan opening for the lever, and a slide disposed over and closing said opening and penetrated by and loosely connected to said lever, substantially as described.

2. In a blind having pivoted slats, a casing secured to one of the vertical rails of. said blind, a reciprocating rod arranged in said casing and having an eccentric connection with each slat, a suitably-fulcrumed actuating-lever for said rod, saidcasing having an opening for the lever, aslide inclosed in said casing, coveringthe opening and penetrated by and loosely connected to said lever, and means for maintaining said slide in contact with the casing, substantially as-described.

3. In a blind having pivoted slats land provided With an elongated recess formed in the inside of one of its vertical rails, a casing secured over said recess and tothe rail, a reciprocating rod arranged in said casing,

crank-shaped pinsprojecting from each of` saidslats and connectedv to said rod, a` screw or pin penetrating thecasing and projecting into the rail, an actuating-lever fulcrumed on said screw or pin and having a pin-andslot connection with` said rod, said casing having an opening for the lever, a slide inclosed in said casing, covering' the opening and connected to said lever, and means for maintaining said slide in contact with the casin g, substantially as described.

` In testimony that I claim -the foregoing l have hereunto set my hand this 7th day of March, 1899.

GEORGE l-I. HAMALIAN.
