Similar characters of reference indicate similar parts in the several figures of the drawings.
1 indicates a door structure whereinis mounted a vertically slidably window 2 and a rotatable gear 3 provided with an'arm 4i, the extremity 5 of which has roller Contact with the underside of the window whereby the said window maybe raised and lowered by the rotation of the said gear 3 in one or other direction. As the method by which the actual operation of the window is effected by the said gear is'not essential to this invention and lends itself to usewitlr many different mechanical arrangements for actually lifting and lowering a window, further description of this part of the device is not entered into herein, except to explain that in the illustrated arrangement thesaid 'gear 3 is rotatable onfasupportingplatev 6 suitably attached within the structure ofthe door 1, and is provided with a spring 7 acting more or less as a'counterbalance for the window and attached at its outer end to a pin 8 carried by the plate 6, which pinl projects through' an arcuate slot 9 in the gear and acts as astop, limiting the extent to which the said gear may rotate.y
10 is an operatingcrank for effecting the rotation of the gear 3 in one or other direction by means of a' pinion 11 toy which the said crank is indirect-lyconnected as will be further explained, andy this crank has a spindle 12': which passes through an opening 1l in the plate 6 above the gear 3, thel inner projecting end 14 of the said spindle beingl cut away or flattened as at 15 on opposite sides thereof to within a short distance of t-he said plate,
Upon the uncut portion of the spindleextending through the said plate the pinion 11 is freely mounted in mesh with the gear 3 and the plate is provided with' a raised portion 16 about the said pinion 11'to form a support for a disk 17 secured thereto by screws 18, which disk extends over the face of the said pinion and partially over the face of the gear 3, and isprovided with a central' opening 19 of greater diameter than the spindle 12. Thesaid opening admits of thel projection of centrally disposed abutments 2() on the said pinion through said opening, so that they extend into a central rewcess 21 formed in the face of thesaid dish 1f.
The. disk 17 forms the .fixed member or housing of a clutch device which also includes movable members or brakes 22and 23 rotatable in said recess 21 and a clutch releasing and rotating member 24 mounted on the flattened portion 11i of the spindle 12, the said member 24C having an elongated cent-ral orifice 25 conforming to the cross` sectional shape of the flattened portion 14 of the spindle and ensuring the rotation of the said member 2st with the said spindle. The clutch releasing member is provided at its extremities with abutment-s 26 and 27 which enter openings or recesses 2S and 29 in the said movable members 22 and 23 spectively.
lt will be noted that the member 22 is provided with a tongue 22a slidably entering a complementary slot 23 in the member 2B, and that the abutments 2G and 27 of the clutch releasing member are adapted to engagethey innermost faces of the recesses or slots28 and 29 if the said clutch releasing member' be rotated slightly relevant to the members 22- and 23, thereby drawing` the said members 22 and 231 together towards the axis of the spindle.
These members 22 and 23 are provided with outer corners-or friction points 22" and 23", which may frict-ionally engage theI annular wall of the recess 21, but which are'witl drawnv from such engagementtherewith when the said members 22 and 23 are moved inwardlyl therefrom by the clutch releasing member; and as this clutch releasing meniber-is definitely rotatable-with thespindle 12 upon the operation ofthecranlr 10 it accordingly follows that the members 22 and 2? are retracted from the annular wallof th recess 21 whenever thesaid crank is operated in anydirection. Consequently, upon such operation of the crank, the pinion 11 Vis freely rotatedy by reason of the engagement of its abutments 2O in inner recesses 2J and 23Cin the said members 22"'and and the gear 3 also rotated for the raising or lowering` of the window.
lf, however, when the windowk is raised, its weight tends to perform the reverse operation and cause the gear 8 to revolve the pinion 11, the abutments 20 of the said pinion will press the said members 22and 23 outwardly so that theiI friction points will engage the annular wall of the recess 21 of the disk 1T, thereby locking the said members 22 and 23 against rotation in the diss and of course preventing further rotation of theV pinionl 11 by the gear Thus the transmission ofpower from the crank toV the gear for the raising of the window` is effected through the members andJ 23 simultaneously with the effecting of their inward declutching movement, but in transmitting power in the opposite direction from the gear 3 to thepinion, the said pinion effects the clutching` movement of the said members 22 and 23;
The simplicity of this construction is verv apparent. The clutch mechanism does ndt call for the use of springs; the pinion, clutch releasing member, movable clutch members and the fixed clutch member or ring may be stampings, and the machine work required upon the spindle to provide for accommodation of the parts carried thereby amounts to very little.
rlhc clutch releasing member is shown as being surmounted by a washer 80, and a nut 3l over which the end of the spindle is riveted as at 32.
The modified arrangement, Figures 9 to 13 is similar to that already described, but includes a liner or band 33 lining the annular walls of the recess 2l of the disk 17 and which ring 8S is rotatable with the movable members or brakes 22 and 23, the latter of which is shown as being provided with a tongue adapted to enter between inwardly projecting ends 35 of the ring 33 which is split at this point to insure he rotation of the ring with the brake members and thereby protect the brake members and the disk 17 from wear one by the other.
rlhe clutch releasing members 2% are also provided with ear pieces 36, 37, 88 and 39 projecting over the face of the disk 17 and retaining the ring against lateral displacenient, and i0 indicates a roller or wedge member which may be disposed between the brake members and the ring 33 as an aid to the clutching' eiiect.
l attach considerable importance to the fact that my construction admits oi marked thinness in the clutch which makes it both compact and adapts it to incorporation in very thin doors or structures; and also to the fact that the parts, and especially the pinion, may consist almost entirely or" stampings, the lugs 20 of the said pinion being simply formed in the stamping operation.
rlhis invention may be developed within tie scope of the following claims without departing from the essential features of the said invention, and it is desired that the speciiication and drawings be read as inerely illustrative and not in a limiting sense,
yric-pt as necessitated by the prior art.
