OVERHEAD SASI-I-PULLEY.

Loeonaa Specification of Letters Patent.

Application iled April 10, 1912.

To all whom t may concern: Y

Be it known that I, CHARLES Turnus, a subject of the King of Great Britain, at present residing at the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Overhead Sash-Pulley, of which the following is a full, clear, and exact description.

The invention relates to the type of pulleys known as overhead pulleys, and an essential characteristic of which is that the chain or cord extends upward from the top of the sash and continues in the upward di rection through the top of the window frame, as distinguished from the ordinary style pulley in which the pulley casing is simply mortised into the stile, and in connection with which the sash cord or chain extends laterally over the pulley through the stile.

With an overhead pulley formed and arranged in accordance with my invention, an opening for the insertion and removal of the pulley is provided, formed partly in the stile by cutting the same away at its upper end, and partly in the adjacent end of the top member of the frame, the pulley housing and its bracket being so formed and arranged that the face plate of the housing will range vertically, and the pulley housing will project in front and in the rear beyond the face plate, the front projecting portion of the housing being preferably in the'form of a laterally deflected member which closes that portion of the opening formed in the top member of the frame, while the rear of the pulley housing will extend rearwardly beyond the face plate and beyond the stile, whereby the chain will drop at the front from the pulley at a point above the stile and parallel with the face of the stile, outside of the same, to a conneption with the sash, while the chain or cord at the back will drop to the weight at a point rearward of the back face of the stile from a point on the pulley above the stile and outward and rearward of the latter suiciently for the weight to clear the end ofthe stile.

In connect-ion with the pulley, a housing, and a face plate as described, I employ a bracket member integral with the housing and face plate, and formed with a foot presenting a horizontal shoulder or under surface ranging in a rearward direction at right angles to the back of the face plate, and sidewise to present an area approximately equal to the total top surface of the stile at the cutaway portion thereof, whereby the weight of the sash and sash weight will be exerted in a downward direction on the horizontal foot of the bracket and its broad under surface, and directly against the upper end of the stile and in the direction of the lengt-h of the stile. By my arrangement I avoid exerting a leverage on the top member of the frame through the bracket and face plate, and I avoid the use ofva horizontal face plate engaging the top member of the frame; at the same time while providing a vertical face plate for closing the opening at the top of the stile, I cause the weight, as stated, to be exerted downward directly in line with the stile and through a member at right angles to the face plate, and overcome the tendency of the sash weight to rock the pulley housing "and face plate. The form of the opening at the upper angle of the frame and partially in the stile and partially in the top member of the frame facilitates the positioning of the pulley, its housing, and face plate, and when the pulley is in place, the openings are substantially closed by the housing and face plate.

The distinguishing features of my invention, and the important structural elements characterizing the preferred embodiment which is illustrated as an example, will be more particularly explained in the specific description hereinafter to be given.

Reference is to be had to the accompany ing drawings forming a part of this specilication, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a perspective view of my improved overhead pulley and its appurtenances, in position, and indicating in dotted lines port-ions of the window frame, sash, the chain or cord, and the sash weight; and Fig. 2 is a rear elevation of my improved overhead-pulley with parts of the housing and bracket in section.

In constructing an overhead pulley and its appurtenances in accordance with the form illustrated, the pulley l0 is journaled at its center, as at 11, to revolve in the housing 12, and integral with said housing and depending therefrom, in a line slightly in front of the center of the pulley are depending webs 13 constituting a bracket, integral with the the faceplate 1-1;ex ten'ds laterally beyond` the bracket webs 13, to effectively conceal the latter. The lower ends of the vertical bracket webs 13 are extended rearwardly, as at 17, andare formed integral with a foot 1S forming the lower end of the bracket.

The housing 12 of the pulley is generally of rounded form at the topth`e upper portion` 19 being desir-ably in the arc of a circle4 having the axis 11 of thepulley as the center, saidjupper portion of the housing being'V practice,` adjacent to the lintel' 30. The housing at the front hasa wider curve, beingI deflected outward,`as at 21, the lower edge ofy which, at the outer portion ofthe housing, terminates as at 22 on a line which whfen the' pulley is in place, will be flush with. the top member 40 of the window frame.l The lower edge of the front portion oftliepulley is advantageously cut away, as atf23, at, both sides, to prevent: the pos'- sibility of the chain catching the lower edge in the raising anddowering of the sash 50.

In. practice, the housing carrying the pulley is. entered diagonally through an opening formed' partially in the stile and partially inthe top frame 40 at the angle of saidjmembers, the stile being cutaway at its upper end as at. 25, and the top frame 40 being cut away adjacent to the opening 25, asiat 26.; After the pulley and the upper end of the housing of the described pulley areentered, the housing with its face plate andiitsbracket members 13 are brought` to such a position that the face plate is let'into the. face of the stile 2O to lie flush with the latter, andj a screw passed into the hole 16 secures the pulley in place,- with the foot 18 resting onthe top surface'QOa of the stile. It. will b el observed that the foot 18 extends atrig'ht angles to the rear side of the face platte 1 5', and has a width laterally so that the total'areal is approximately that of the tcp 2,0a `of the stile. Thechain leaving theI pulley at diametrically opposite sides will' cause the sashv weight 60 to be raised andjlowered ina path clear ofthe back of the st ilemfZO, andjat the front said chain will departfrom the pulley at a point within the opening 2,6 formediin the top member 40 of the' frame, and extends to the connection 2K7 with thesash on a line outside of the face plate,Y It willbe seen also that the horizsoutalju foot 18kv of the bracket 13 extends rearwardly to a verticalline passing through the center '11. of' the pulley, and therefore is in linewith' l thendownward pressure exerted by the' sash andfweight. The foot presents a broad area and rests directly on the seat Q0a provided by the cutaway upper end of the stile. At the front, the outward and downward extension of the housing, as at 21, 22, fills the opening in the top frame `member 40 through which the chain passes from the sash to the pulley.

f rllhus the' improved housing with the appurtenances described enables me to form the most convenient opening for the entrance and removal of the pulley and housing, which opening is edectively closed bythe face plate and the laterally deflected front end of the housing, and by my improved construct-ion' I obtain yall the advantages of the overhead pulley while providing the most effective resistance against the strain by transferring` the same directlyl in line with the stile. Moreover, the direct downward strain of the sash and sash weight overcomes all tendency of the sashweight to exert a leverage on the face plate, and relieves the frame members of any strain or leverage exerted transversely ofthe face plate.

In all large buildings it is the custom to make up and it the window frames. as the building progresses, the fitting and placing of the sash pulleys being deferred until the window frames are all in place, in order that the pulleys and their housings may notbecome rusted, in the case of iron, or tarnished in the case of other metalsbefore t-he completionk of the building.

lith my invention itis evident that overhead pulleys may be secured in position after the window frames are in place, which is a very important consideration as compared with pulleys that need to be fitted in the frame before the frame is placed in the building. and 4frame permit of the pulley being readily removed when required, without taking the frame apart.

Having thus described my invention, I claim as new, anddesire tojsecure by LetL ters Patent,
