Referring in detail of thedrawing.:`

. Numeral 1 `indicates a window which `is adapted to be'.y r'eciprocated vertically in :a suitable"frame,the lowerpar't ofwhich is indicated at 2; Numeral 3 indicatesa plate which is mounted on and secured to the lower-part 2 in any desirable manner while g. 2 `1s ak front yeleva-tion of'one of the slidable plates employed onA the lowercon'f i' to the `"several, rfigures 4 indicates a cover platemwhi'ch is screwed to saidv plate by suitable screws 5 and which forms with-sindy lute 3 a' housing containing a clutchv 'and other` mechanism to be presently described. A vertical depending bafr or strap Slis fastened at its upper end to the plate 3 and at its lower end to a` cross-bar 7 which is detachabl secured to theilside 4walls of other parts o thewindow we The ybar 6 is yprovided adjacent its-lower end with twov slots8 'and 9 respectively, the slot 8 being so cut in the material as to' form an arm 10. 11 and 12 indicate vertically slidabl'e plates each of which2 is provided with depressions 13rv pressed vinwardly from the metal and actingv as anti-frictionmem- -bers slidably engaging the bar or strap 6. The upper `ends of said plates 11 and 12 are bent'inwar'dly into engagement with each other Vand within the Slot'S to form a shoulder 14. A com pres'sion' spring 15 encircles the arm 10 an the u per .inwardly bent ends-"of Athe platesr and) bears against the y shoulder 14 and actstofpress' or force said4 ig. 'l is afrontelevatlon of the windowv plates. downwardly on the bar or strap 6.

y A bolt 16 extends through the slot 9 in the barn and Ialso through suitable annular openings in the plates: 1'1 and 12. Said bolt is'prOVidedwith ears or shoulders-17 engagingin slots 18 in plate 12-which slots communicateywith the bolt-receiving opening in saidplate. The engagement of'said ears with vsaid slotsA acts to 'prevent rotation of'said bolt. The hub portion 19 of a lower rotatable sprocket 20 is mounted on the en' larged annular portion 21'o'fA the bolt 16, a

longitudinal movement of said sprocket on said portion 21 bein prevented by la flange 22 on said bolt and y an annular ridge 423l on theplate 12 whichfis" pressed Aoutwardly from Athe, metal and which engages the side of the hub portion 19. `A` nut 24 is screwed i on the end of thebolt and holds vthe plates together'as is manifest, a washer 25 prefer ably being-interposed between said `nut and 4late. 11 and seatm onf-a shoulder 26 formed y a depression? lWit whichsaid plate is pro` v1ded. f

An endless driving chain 27 passes over an upper sprocket 28, which is mounted on the plate?) in a manner to be presently described, saidchainibein'g heldtaut by the actiony of the spring 15 which, as has been described,

loo

presses downwardly against the vertically slidable plates 1l and 12 carrying the lower sprocket 20, thus preventing the chain from running off said sprockets. The chain 27 is connected to the window 1 by means of a roller stud 29 engaging in a slot of a plate 30 which is secured to and depends from the lower side of the window. A handle 31 is mounted on a housing and connected with mechanism within said housing formed by the cover plate 4 and plate 3 whereby rotation of said handle will rotate the upper sprocket 28, thereby cansino' the chain 27 to travel around the upper and lower sprockets thus effecting a raising and lowering of the window depending on the direction of rotation given the handle.

Numeral 32 indicates a crank shaft which is provided with enlarged and reduced hub portions 33 and 34 rotatably received by an annular neck 35 pressed out from the plate 4 and a removable bearing 36 respectively which bearing is received and held within an o ening in the plate 3. (See Fig. 6.) The iandle or crank 3l is secured to the end of said shaft in any desirable manner. The shaft is provided with a substantially rectangular-shaped driving-member actuator 37 preerably integral therewith and having fiat sides and rounded ends and also end flanges 38 slidably fitting intermediate the plate 4 and ae fixed clutch member 39. The flanges 38 act to prevent rocking or dis lacement of a clutch driving member 42 to e presently described. y

The fixed clutch member 39 is provided with pins 40 extending through depressions in the plate 4 the ends of said pins being riveted 4over on said plate within said depressions, whereby the clutch member is securely held against movement. Said clutch mem ber is also provided with an enlarged opening 4l extending tlierethrou h having a serrated or toothed ed e as in icated. i

The driving mem er of the clutch is indicated at 42 and is provided with outwardly projecting ins 43 and an opening 44 having an upper fat wall, rounded side walls and a lower wall having an irregular or cam surface. (See Fig. 9.) The lower portion of the driving member is also provided with teeth 45 adapted to interlit with the teeth ot the opening 41 of the iiXed member 39. The openin r 44 is adapted to receive the actuator 37 on t ie shaft 32 and the opening 41 of the fixed clutch member 39 receives the driving member 42, the fixed clutch member and driving member 42 both lying in the saine plane. Then the handle or crank on the shaft 32 is not rotated or operated one of the flat sides of the actuator 37 engages the upper fiat wall of the opening 44 while its curved ends engage the rounded side walls of said opening as shown in Fig. 5.

Numeral 46 indicates the driven ymember loosely carried on the shaft andwhich comprises a flat disk provided ,with slots 47 therein slidably receiving the pins 43 of the driving member 42. (lne of said slots carries a spring 43 beariii against one of the pins 43 and acts to retain the driving member 42 in the position shown in Fig. 5 with its teeth 45 lockingly engaging the-teeth of the fixed member 39, whereby rotation of the shaft 32 will be prevented if rotation is attempted rom the end adjacent the hub portion 34 as is obvious.

The driven member `46 is provided with outwardly projecting pins 49 entering and interiitting with suitable openings in a pinion 50 loosely mounted on the shaft, said pinion meshing with a large ear 51. When the crank or handle is rotate the part 37 of the shaft takes the position shown in Fig. 9 or at right angles to said-position depending on the direction of rotation of the crank or handle. As the pa'rt 37 may not completely rotate within the opening 44 it forces the driving member against the action of the spring 48 to move in a direction whereby the teeth 45 will become disengaged from the teeth of the fixed member 39, after which the member 42 will rotate with the shaft. Rotation of the shaft thus effects a rotation of the driven member 46 due tothe pins 43 en gaging in the slots 47. When the driven member rotates the pinion 50 and ,large gear 51 likewise rotate because of the connection between these parts as hereinbefore described. When the crank or handle is released .the parts automatically lock as the spring48 bearing against one of the pins 43 acts to move the driving member 42 into its first position whereby its teeth 45 will engage the teeth of the fixed member 39, the part 37 being also forced back into normal position shown in Fig. 5. For all practical purposes the driven member 46 and pinion 50 may be considered one part, they being constructed of two parts merely for convenience of manufacture. y

The gear 5l is fixed to a shaft 52 provided with a flange 53 acting as a stop to prevent a longitudinal movement of the gear thereon. One end of said shaft 52 is hollowed out as at 54, this end of the shaft being supported by a depressed support 55 pressed inwardly from the metal of the plate 4 and entering the liollowed out portion 54. The other end of the shaft is mounted in an annular neck 56 pressed out from the metal of the plate 3 and forming a bearing for said shaft, a washer 57 being preferably interposed between said bearing and shaft. The plate 3 is also provided with an annular ridge or bead 58 pressed inwardly from the plate and acting as an anti-friction support slidably engaging the side of the gear 51 and adapted to prevent rockin thereof. The end of the shaft 52 is reduc and relll() llO ceivesthe sprocket 28 which is rot-atable `therewith and which is adapted to engage a shoulder 59 on the shaft to prevent a lonwith a head 61 received by the recess54.

The opposite end of said bolt carries va washer 62 adapted to prevent removal of the sprocket from the shaft.

The plate 4 is provided with an inwardly extending lu 63 vcut from the metal to which one en of a counte'rbalancing spring 64 is secured or hooked, the other end of said spring being secured or hooked to a lug 65 on the gear 51. The sprin is supported andprevented from sprea in outwardly by additional lugsy 66 on sai gear and is prevented from too great an inward movement, which might tend to interfere with the rotation of the shaft 52, by a semiciroular shapedV ridge or` bead 67 pressedv inwardly from the plate. The counterbalancing spring per se is old although in so far as we are aware the Vparticular manner of mounting and holdin the same in proper position as shown an 4described is new. The function of the spring is to assist in the raisingof the window, the spring befl 'ino' wound up by thel lowering thereof.
