rre resent windows ada'te'd .to swing later- ALBERT K. LOVELL, OF NEW YORK, N. Y.


Specification of Letters Patent.

Patented March 10, 1908.

Application filed December 17, 1903. Serial No. 185,554;

To all'whcm it mag concern:

Be it known that I, ALBERT K. LovELL, a citizen of: the United States, and a resident of N ewi' York-,in the county-of New York and State of New .York;fhave invented certain new and useful Improvements in Window er Shutter. Operating .Devices, of which the following is a'specification,

My invention relates to window or shutter operating devices, andit consists certain details of construction to bemore fully set forth in the following-specification, and the features believed to be-newand novel will be set forth in the'cla'ims'.

To enable others toiinderstand hiyinvention, reference is bad to the accompanying drawings in which: 7

- Figure 1 representsan elevation of closed windows or shutters, as the case may be, and

a broken viewof their operating-rods; Fig. 2 is a sectional view of the-wall andtop view of thewindows online 2 of Fig. 1, a broken "'view of the operating-rods, and a view in dotted lines of the" partially open windows; Fig. 3 is a detail lan view ofone of'the window-brackets a apted for use when the windows or shutters are tobe lapped one over the other againstthe building; Fig. ,4, is a view of one o the, driver pins and aisectional tiew of-the operating-rods mounted in LCOllBJ'S' adjustably secured to'said pin; Fig. 5

is a detail view of one of the driver-pins and'a sectional view of one of the window-brackets; Fig. 6 is elevation of closed windows adapted to be opened or closed in the same direction; Fig. 7 is ar'educed view of a series of windows arranged to .move'one in advance of the other, also broken view of the o eratilrlig-rods, and broken sectional-view of t e wa The construction and operationof my device are-asfollows: 1 and 2, Figs. 1 and 2,

y on the bin es 3 rackets 4 and 5 are secured tothe ottom of'the sashes. These brackets are rovided with the inclined slots 41*; and 5; t e clearly pins on whic ed. These drive-pins are adjustably secured these slots are loosely fitted to the-collars 10, 11, 12 and 13. 14 and I5 are the window. operating rods, and 16 are supports in which these rods are adapted to move freely;

The apparatus ooved rollers, 6 and 7,' sho wn more at Fi s 4 and5., 8and 9 bemg-dnves g these'rollers are freely mountis intended for usein con-' nection with a long series or line of windows or shutters. As it is thus applicable to either windows or shutters, and to avoid a repetition of terms, Iwill, in future, designate them-as windowsf The operatingrods 14 and 15 are actuated to move in oppositedirectionspasindicated by the arrows I, '1, where'the windows are to be moved in opposite directions and by mechan- The operating-rods are free to move in each alternate collar, for instance, Figs. 1

and'4 the ,upper rod 14 is adjiistablysecured 12 and is adjustably securedjto the collar 13 by thefset-screw13. By this arrangement, the operating rods are allowed to move in opposite directions to 0 en the windows in opposite directions, an means visl prov'ided for maintaining th'eLdrive-pins in a vertical position. But. when all. the windows are intended to be moved in the same direction,

.ism, not shown, located at any desired position on'the line.

. '76 to the collar 10 by means of the screw 10, but is allowed to run free "in the collar, while the lower rod 15 runs free in the collar especially when the windows are very heavy, I

the set screws 11:? and 13%, Figf 6 may secure the coliars l'l and 13 to the operating rods, which r0dswill-.then both be moved in the same direction; But when. the windows a are light,"theset screws IP-can be loosened so that the upper ro'dlcan move freely in the collars 11.

I Inoperating the device, shown .at Figs. 1 and 2, toopen the windows, the rods are actuated, as before mentioned, in the direction of the arrows a b. This'will force the grooved rolls-f6 and 7 of the 'driveins against the outer edges of the inclined s ots 4 and p 5 of the. window brackets,- which operation will cause the windows 1 and 2 to swingpen. The control of the windows b means of thetop'eratin mechanism is sucl i thatthe windows may e firmly held in any position from the closed position to the ex- .treme o enipositionf'as shown .by dotted lines in 1g.. 2.

To fold windowsthat are set close together one over the othe'r against the. wan, I make the upper endsof the slots in the; windowbrackets of eachalternate window straight or, parallel with thewindow, asshown at'4", Figs. 3 and 7,. Owing to this it is apparent that the windows 2 will start to openlor swing outward on the slightest movement ofqthe' operating-rods, but while the drivewindows 2 to 'pins 8 are travelin along the straight portion 4* of the brac ets 4 the windows 1 will brought against the wall or building A, the slower moving windows 1. will be folded against the m.

It will. be understood that the construction abovedescribedican be used for opening" one or more windows fromthe inside or from the outside ofa building. a

Having thus describe myi'nvention, what I claim as new and desire to secure by Letters Patent is:

..'1. A window operating device adapted to operate a plurality-of windows in opposite directions, comprising a bracket secured to each window, operating-rods parallel with veach'other and located adjacent to the win- (lows and" adapted to move in'opposite directions, said brackets having slots angularly inclined with respect to said rods and windows and oppositely inclined with respect to each other, supports for said rods, a collar oneach of said rods in front of each window, 'said collars being in vertical alinement with each other, a drive-pin carried by each air of collars and projecting within said s ots, for the purpose set forth.

2. A window operating device adapted to operate a plurality of windows in opposite dlrections, comprising a bracket secured to eachwindow, operatingrods parallel with each .other and located adjacent to the windows and adapted to move in opposite directions, said brackets having slots an ularly inclined with respect to said rods an oppositely inclined with respect to each other, collars on each of said rods arranged in pairs and in vertical alinement with each other, a drive-pin carried by each pairof collars and projecting within the bracket-slots, the outer end of the bracket-slots in each alternate window being rovided with a straight portion substantial y parallel with the opcrating-rods so as to cause the windows thus equipped to stand still while the windows having bracket-slots without said straight portions will start to open first, for the purpose set forth.

3. A window operating device adapted to operate a plurality of windows, comprising a bracket secured to each window, 0 cratingrods parallel with each other an located adjacent to thewindows, a support for said rods, said brackets having slots an ularly inclined 'with respect to said rods, col are on said rods arranged in pairs and in vertical alinement with each other, a drive-pin carried by each pair of collars and projecting within the bracket slots, for the purpose set forth.

Signed at Bridgeport in the' county of Fairfield and State of Connecticut this 20th day of Nov. A. D. 1903.
