WINDOlV-OPEIt-ATING DEVICE.

To all whom it muj l concern Be it known that we, Annow HOLMES, a citizen of the United States, residing at Highland Park, in the county of Delaware and State of Pennsylvania, and VVILSON D. CRAIG \Viiiei-rr, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Penn-.

and to characters of reference marked there on, which form a part of this specification.

The present invention has reference, generally, to improvements in window operating devices; and, the invention relates more particularly "to a novel and simple construction of mechanism adapted to be connected with a, window whereby thesaine mag be easily and qnicklyi'aised or lowered ya simple operation requiring little effort 01' muscular exertion.

The invention has for its principal obpect to provide a self-balancing opening and closing mechanism for connection with any type of window, but more particularly adapted for use with the windows and doors of limousine automobile bodies,coarhes, railway carriages and similar vehicles. To this end the present invention provides a sprocket and chain mechanism for produciug the throw or movement of the window, the same hcin; operated. by means of a handle means through a .reduction gearing transmission whereby the weight cf the window is offset by the power multiplication of said gearing. ln addition to the above arrangement the said-handle means is constructed so as to he selfdoekina for the purpcse of maintaining the window locked in any position. open, closed or inter mediate of said open and closed position.

Other objects of the present inrention. not at this time more particularly enumerated. will be nearly understood from the following detailed description of the said invention.

The said invention consists, primarily. in the novel. window opening :and

handle means; and Fig. 8 is a cross-section: of the same, taken on line 88 in Said Fig;

I between its outer and inner wall, and

riiou'nted' preferably upon said inner wall dis a base-plate 5, the same being se-- chred inj'said mounted position by means of sc rews 6,'or1any other desirable form of fastening means. Connected with said baseplate 5,'so as to project therefrom at a suitable location, ,is a stud or-gjournal 7, and

mounted to rotate u on saidjournal or stud .7. is h sp'i'dckct-whee 8, of suitable diameter so as to 1provide a circumference which equals or s ightly exceeds the maximum distance of the throw or moi ementof said -windowmember 3 in its guides 2.

-.-The reference character 9 indicates a sprocket-chain adapted to run upon and be operated by said sproeketswheel 8. Said sprocket-chain 9 is secured by one end, by

means of anchor-links 10, to the body of said sprocket-wheel 8, and the sprocketchain 9 then-extends, normally, around the circumference of said sprocket-wheel 8 and in proper engagement with the sprocketteeth 11 of the latter. Connected with the free end of said sprocket-chain 9 is a trans versely extending'cross-pin 1.2, which provided at one end with an enlirged hatchportion 18 thro gh which saiu llanged antifrictionroller 3 may be inserted to carry the same into said slot 15, so that its fian es 14 fengagethe marginal edges of said slot to thus prhyentdisplacement of said antifriction rbller l3 from'its properly associated relation to said pull-piece 16.

Mounted upon said base-plate 5, and spaced therefrom by the spacing-block 19 and the holding angle-pieces 20, so as to lie in the plane of said sprocket-wheel 8 and tfiigent thereto, is a vertically extending cliinh-guide or runway 21, the wall 22 of which is cutaway at its upper end so that said sprocket-wheel 8 carrying the sprocketchain= 9.-may' enterthereim so secured in the'uppei' end of-{said chain-guide or runway 21 is aguide-hlock 23, which projects over said srocket-wheel 8 and sprocket-chain 9',

and t e curved under surface 24 of which provides a guide for guiding the free end of said sprocket-chain 9 down into said chainsguide or runway 21 so as' to cause the former to enter the latter. Said chainguide or runwa 21-is rovided in its front wall, 25 with a ongitu inall extending slot or opening 26 through whic passes or pro jects said cross-pin 12 connected with the free end of said s'procket chain 9, when the latter enters and travels in said chain-guide or runway 21. I,

The reference character 27 indicates a.

plate-member which is secured, by means of 6 a fastening screw 28 to the outer end of said stud or journal 7, and being further secured at one end to a. lug or block '29 projecting from said base-plate 6, by the screw 30,01

other suitable fasteningmeans. As thus positioned said plate-member 27 extendsacrdss if the face of said sprocket-wheel 8, the latter-E- 'hein g thereby retai'ned'against 'r'emoval'f-rom said stud or journal 7, and the end of'said-i' be engaged by said cross-pin 12, thereby serving to guide the same into said slot/or openin 26, and said sprocket 'chain 9 into said main-guide or runway" 21 as said sprocket-chain is paid off from the rotated sprocket-wheel 8.

The reference character 33 indicates a gear-Wheel which is also journaled upon said journal or stud so as to rotate there-- on. Said gear-wheel 83 is secured to said sprocket-wheel 8, so that a rotation of theformer turns the latter, the fastening means comprising screws 34 in combination with spacing-members 35, whereby said sprocketwheel and gear-wheel are not onl 'secured together, but are also spaced away rom each otier so as to allow the unobstructed arrangement of said sprocket-chain 9 with said sprocket-wheel.

The reference character 36 indicates a, pinion which mesheswith said gear-wheel 33. Said pinion is provided withhub-portiors 37 and 38, the hub-portion 37 being journaL-ed in a. bearing opening 39 provided therefor in said base plate 5, and the hubportion being journaled in a bearin opening 4 formed in a yoke-block 41 whic is secured to said base-plate 5 so as to straddle said pinion 36. Said pinion is provided with a rectangular opening 42 for the reception of the rectangula'rly formed end 43 of the stem 44 of a handle-member 45, the

rotation of which serves to rotate said pinion 36, therebyin turn rotating said gearwheel 33 and said sprocket-wheel 8 connected with the latter.

The referen a) character 48 indicates a plate-member having a centrally positioned tubular bearing-portion 47- in which said stem 44 of the handle-member 45 is journaled, said plate-member 46 being counter sunk in the outer surface of said inner wall 1 of the window or door frame 1 The reference character 48- indicates a face-plate adapted to be registered over said and consequently turns said sprocket-wheel of said sprocket-chain 9 carries said crosssaid stem. 44 at said handle-member 45 extends. The end-wallofsaid casing portion. 49 is provided with a plurality or series'of stopreceivingperforations '50. Secured to said stem 44 of said handle-member 45, so.

as to be located. within said casing portion 49 is a disk or flange 51 arranged to rotate with said 'stemuand handlc momberq Said disk or flange 51 carries thereon an outwardly projecting stop-stud 52 which may be selectively registered with any one of said stop-receiving perforations 50, so as to enter the same, and thereby lock said stem and handle-member at the end of various degrees of operation or rotation of the same. A coil-spring- 53 arranged in back of said disk or flange 51, causes an outward longitudinal movement of said stemand handlemember when the latter is released,- whereby said stop-stud 52 is projected into one of the said stop-receiving openings. Said stem and handle-member being therefore capable of a longitudinal movement, as well as a rotating movement, such movement is allowed for when connecting said rectangularly formed end 43 of said stem in said rectangular opening 42 of saidpinion 36, so thatthe requisite amount of longitudinal play of the formerin the latter isprovided for, while yet maintaining their coupled relation so that the rotation of said handle-member and stem will rotate said pinion, 36, and eonse uently said gear-wheel 33 and sprocket-wheel 8 driven thereby.

In the.operation-'of the above described mechanism, assuming that the window is closed, asshown in Fig. 1, and it is desired to open the same, as shown in Fig. 2, said handle-member 45 is first pushed inward to produce a longitudinal movement of said stem 44 which carries inward said disk or flange 51 against the compression of the coil-spring 53, thereby withdrawing said stop-stud 52 from engagement with one of said stop-receiving perforations 50, and consequently freeing said handle-member 45 from its locked condition,- allowing the same to be rotated. The rotation of said handlemember 45 and its stem 44 rotates said pinion 36, which ineshingwith said gear-wheel 33 transmits the rotary movement thereto 8. In thus turning said sprocket-wheel 8 the sprocket-chain 9 is paid off of the same, and the free end of said sprocket-chain moves toward the guide-block 23, the curved surface 24 of which holds said chain in engagement with the teeth of said sprocket-wheel-. 8 until the entrance of said chain-guide or runway 21 is reached. Since the free. end' ment.

downwardly in. said chain-guide or runway pin l2 and antifriction roller 13- which is coupledwitli. the pull-piece16 of the. windowmember 3, the downward movement of the free end of said sprocket-chain, as it follows around the moving sprocl ret wheel 8, exerts a (lownwardpull uponsaid window-member 3 which. starts its lowering or opening move The forward'movement of said. firee end ofi said sprocket-chain, cross-pin and anti-firictio-n roller, being. compensated for by the traveling movement of said roller 13 in the slot 15 of said pull-piece, since themovement. of said free end-of the chain becomes vertical only after entering said chainguide or runway 21. As the rotation ofi'said sprocket-wheel. 8 continues said free end of the sprocketchain 9 is carried downward into said. chain-guide or runway 21, and said cross-pin 12 engages said gu'idingedge of the guide-member 31 so as; to cause the same to ride into said slot or opening 26 of the front wall 25 of said cha-in guide or rnnivay 21, with the effectof causing the sprocket-chain 9 to leave or remove from said sprocket-wheel 8- andcontinue to travel 21. Said sprocket-chain 9 being inc-losed by said chain-guide or runway2l, the same 'is P evented from buckling or bending,.so

that the body of the same is forced to travel downwardly in said chain-guide or runway 21, the free end carrying said cross pin 12 and roller 13 also traveling downward and therefore continuing to pull downwardly upon said pull-piece 16' and the window-- member 3 connected therewith, whereby the latter is moved to its open position.

Since the pinion 36 is reduced in proportion to the gear-wheel 33, the power applied by the handle-member is multiplied so that a very little exertion will accomplish the movement ofthe window either up or down, and, furthermore, the positive connection of the chain with thesprocket-wheel 8, and the geared connection of the latter with the no handle-member in effect balances the win-- dow-member so that the same is maintained in the position to which it is moved, but even if such were not the case, the s'elf-locking feature of the handle-member-when the spring 53 forces the stop-stud into a stopreceiving opening, as above described, will rotated in the opposite direction. to turn in the opposite direction the gear-wheel 33 and sprockehwheel 8 whereby the sprocketchain is wound up on said sprocket-wheel, and by the direct pull of such operation the. 15

.windoW-member is also moved upward to-- 'j-closed position or. any intermediate closed position. a Y

I I t will be a'pparent thatahe'above appar'atus'is simple ,both in construction and jperation, requiring little efi'ort'to operate and being. positive in the application of the multiplied moving force to the Window.
