Mounted in the well 4 and attached to transverse members 7 and 3, against the panel 5, is a vertically disposed sheet metal casing 9 having a cover 10 attached to the casing 9 by screws 11 or other fastening means and said casing is preferably located and 15 respectively and journaled in said bearings is a binding arbor or shaft 16 having a shank or tang 17 on which is mounted a crank or operating handle 18. The bearing 15 extends through the panel 5 so that the crank or handle 18 may be operated at the inner side of the door or wall.

Suitably fixed on the arbor 1G is a com pound wheel which may be made of two parts out and stamped from metal with the parts thereof spot welded or otherwise connected together, but in some instances the compound wheel may be a homogeneous mass with the periphery thereof having a configuration which will serve two purposes. As shown, one part of the compound wheel is in the form of a chain driving member 19 and the other part in the form of achain supporting member 20. The periphery of the chain driving member 19 is provided with equally spaced recesses or pockets 21 for chain studs 22, said studs being carried intermediate the ends of the links 23 and 24 pivotally connected together by rivets or studs 2 Each alternating link 21 may be composed of two parts held together by the studs 22 and the ends of the two parts may be pressed and apertured so as to provide opposed ears between which may extend the apertured ends of the links 23. \Vith the links 23 and 24L cut or stamped from sheet metal the chain can be easily and quickly made and its links readily articulated to afford a] comparatively fiat flexible member and one end of said member is adapted to support the sash 3. For this purpose an end link ofthe chain is provided with a right angular tubular extension 26 which in some instances may be connected direct to a bottom rail 27 of the sash 3, or may be provided with a roller 25 to roll against a bottom channel rail 27 on the lower edge of the sash 3. I prefer to fix a wide sash supporting member 28 on an angular extension 26 of the lowermost link 23 and provide the ends of the supporting member 2-8 with spools or flanged rollers 29 on which the rail 27 rests for supporting the sash 3 in the guides 2. The supporting member 28 is in the form of a long head or beam which will provide a long support for the sash relative to the chain and in consequence of this long support the sash will be evenly supported for uniform movement in the guides 2, it being practically impossible for the sash 3 to cant and bind against the guides during its movement. This is also brought about by the casing guiding the chain and by positioning the sash regulating device so that the raising and lowering end of the chain will be approximately in termediate the ends of the rail 27.

The chain supporting member 20 has its periphery formed with flat sides or facets 30 and as shown in Fig. 6, the member is hexagonal so that two or more of the facets 30 may atall times cooperate in supporting two or more links of the chain. This chain supporting member will sustain the weight of the sash through the medium of the chain and relieve the chain driving member 19 of stresses and strains, particularly at its driving connections with the chain.

Since one end of the chain is free provision has been made for guiding the chain in its movement so that there will be no danger of accidental displacement of the chain relative to the compound drive wheel on the arbor 16. The cover 10 being fastened directly to the casing 9 has its 1011- gitudinal edgesoif-set, as at 31, to cooperate with the edges 32 of the casing 9 in forming longitudinal channels 33 for the chain, the channel extending up over the compound wheel, as best shown in Figs. 6 and 9. In addition to the channel guide for the chain the casing 9 has a depressed way or groove 3% providing clearance for ends of the rivets 25 and studs 22, and it is the channel guide and groove which retains the supporting end of the chain always perpendicular for supporting the sash properly in the sash guides 2.

Mounted on the arbor 17 in the housing 4 12 of the casing 9 is an eccentric 35 and loosely mounted on said eccentric is a toothed inner clutch member 36 normally engaging a toothed outer clutch member 37 which is fixed in the housing 12 by any suit able means. Attached to the side face of the outer clutch member 37, by spot welding or other fastening means, is a spacing ring 38 providing clearance for an outer locking member 39 secured to the face of the inner clutch member 36 by spot welding or other fastening means. The outer locking member 39 has an oblong opening 10 providing clearance for an inner locking member 11 on which slides the outer locking member 39,

- actuated except by han and i the inner locking member 41:has an oblong opening .42so that the inner locking member'may slide on a head 43 loose on the arbor 16 and secured tov the compound wheel by spot welding=or other fastening means. The constructive arrangement of the locking members 39 and i1 is such that during the eccentric movement of the inner clutch member 36 the locking members are caused to shift, but irrespective of the location of the inner clutch member relative to the outer clutch member it will be impossible for any load sustained by the compound wheel of the arbor '16 to rotate said arbor, thus affording a novel" eccentric or irreversible gearing. In other words, the locking members hold the arbor 16 and the inner clutch member relative to the outer fixed clutch member so that the arbor 16 can be only rotated by hand, thus providing an automatic locking mechanism which prevents the sash regulatin device from being 5 power appliedby the handle or crank 18 or a likeelement. The action of the locking members is best understood by reference toFig. 7 where; the

inner and outer locking members are shown in position to slide as the inner clutch member is eccentrically moved about in constant meshwith the outer clutch member. The meshing teeth of the clutch members are of such configurationthat the arbor 16 can be turned clockwise or counter-clockwise and in either instance held against accidental rotation when released' The downward movement of the sash 3 will be limitedjby the lower ends of the guides 2 or any suitable stop placed in the well l, and the upward movement of the sash 3 may be limited by closing the channel gui'de of the casing, over the compound wheel, so, that the 1 chain extension 26, or 26 will engage the closed end of the channel guide, thus preventing the operating mechanism. from completely releasing the chain. 1

I. attach considerable importance to the fact that the greater part of the sashregulating device is made from stampings, in contradistinction .to drop forgings, consequently those parts subjected to wear can be easily hardened and all of the parts readily' assembled to provide an extremely light, flatrand'. durable device for adjusting a sash, closure or other movable structure While in the drawings there is illustrated a preferred embodiment of my invention, it is to be understood that the structural elements are susceptible to such variations and modifications as fall within the scope of the appended claims.

What I claim is: r

1. A clutch for a sash regulating device including an arbor, a wheel, and a flexible memberadapted for raising and lowering asash :said clutch being adapted for holding the sash and flexible member in an adjusted position, said clutch comprising a fixed outer clutch member, an arbor actuated inner clutch member normally engag-' ing said fixed outer clutch member, and

locking members interposed between said wheel and said inner clutch member normal 1y establishing a driving relation for said wheel by said arbor and precluding any driving of said arbor by said wheel.

2. A clutch as called for in claim 1, wherein said inner'clutch member is eccentrically a wheel are included as elements of a sash raising and lowering mechanism, said means comprising a fixed outer clutch member, an arbor actuated eccentric driven inner clutch member in said outer clutch member, and gyrating means establishing a driving relation between inner clutch member and said wheel.

6. Clutch means as called for in claim 5, wherein said gyrating means includes a head loose on said shaft and fixed tosaid wheel,and members slidable relative to. said head, one of said members being fixed to said inner clutch member.

7. The combination with a sash, a chain for moving said sash, an arbor, a wheel loose on said arbor and over which said chain is trained, an outer clutch member, of a clutch, said clutch comprising an inner clutch member normally engaging said outer clutch member and'driven by said arbor, and means articulating said inner clutch member and said wheel so that rotation of said arbor may impart rotation to said wheel.

8. A clutch for a sash regulating device including awinding arbor adapted to actuate a wheel, drum or other rotary. member to cause adjustment of the sash ;.said

clutch being adapted to prevent rotation of i ing members cooperating with said clutch members in preventing adjustment of said sash independent of said winding arbor.

9. A clutch for a sash regulating device including a winding arbor which aotuates a wheel, drum or other rotary member to cause adjustment of the sash ;said clutch preventing rotation of the winding arbor by movement of the sash, said clutch comprising an irreversible gearing disposed about said winding arbor in a plane parallel to the rotary member by which the sash is adjusted and adapted to be actuated by 10 said Winding arbor for sash adjusting purposes.

In testimony whereof I aflix my signature in presence of two witnesses.
