SPECIFICATION forming part of Letters Patent No. 426,792, dated April 29, 1890.

Application filed June 28,1889. Serial No. 315,910. (No model.)

To all whom it may concern.-

Be it known that I, JAMES H. FOOTE, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in VVindow-Sashes; and I do declare the following to be a full, clear, and exact description of the invention, reference being had to th'e accompanying drawings, which form a part of this specification.

This invention relates to those windowsashes which are capable of being raised and lowered within a frame or casing and of being turned on pivots, so as tobe either horizontal or inclined at any position that will be most convenient or effective for cleaning or ventilation; and the first part of my improvements comprises a novel combination of devices for operating a hollow guide that traverses a vertical groove of the frame. Vhen these devices are so operated as to advance the guide laterally within the groove, the sash can then be raised and lowered in unison with said guide; butwhen the latter is retracted within said groove the sash is free to be turned on its pivots, as hereinafter more fully described.

The second part of my improvements comprises a novel combination of devices for locking the pivots, in order that the sash may be retained in an inclined or horizontal position, as hereinafter morefully described.

My improvements further comprise certain details in the construction of the pivot mechanism, the particulars of which will be hereinafter more fully described, and set forth in the claims.

In the annexed drawings, Figure lis a sectionized elevation of one of my pivotbearings for a sliding and swinging window-sash, said sash being arranged to be raised and lowered with the guide. Fig. 2 is a horizontal section of said bearing, taken at the line X X. Fig. 3 is another sectionized elevation, but showing the sash supported by the pivot, so as to be turned thereon. Fig. 4 is a horizontal section thereof, taken at the line YY. Fig. 5 is a front elevation of the face-plate of the case that contains the pivot mechanism. Fig. G is an enlarged vertical section of said case, taken at the line Z Z. Fig. 7 is an enlarged plan of a portion of the guide and the edge plate of the case. Fig. 8 is an enlarged horizontal section of the devices that operate the cam-shaft of said case. Fig. 9 is a detail view of a portion of said shaft.

A represents a portion of a box Window frame or casing, and d is a vertical groove therein, which groove is traversed by a hollow three-sided guide B, that is preferably made of sheet metal, and is usually as long as the sash to which it is applied. This hollow guide has near its mid-length a vertical slot b, traversed by a bolt C, having a notch c at one end and a cylindrical shank c near its opposite end, said bolt being adapted to slide within a vertical slot (Z of a barrel D, Whose periphery is grooved or fluted longitudinally at d.

d is a head on one end of this barrel, which latter is adapted to slide freely within a cylindrical'neck or socket c of the edge plateE of a case F, within which case the principal operative parts are housed, in the manner shown. G is a vertical stop secured within this case, as seen in Fig..6, said stop being furnished with a circular opening g, to admit the boltshank c', and a vertical slot g', through which said bolt passes, the inner end of said bolt having a pair of collars or nuts H H', between which is inserted the free and forked end of a spring I, the fixed extremity of the latter being fastened to a rock-shaft J, carrying a pair of cams K K. These cams are adapted to bear against the lower ends of bent levers L L', pivoted at Z Z to the case and its cap and normallyheld in contactwith thebarrel-head d. Rock-shaft .I is suitably journaledwithin the case and cap and has at one end a socket j, (seen in Fig. 3 and indicated by dotted lines in Fig. 9,) which socket receives a square or other non-circular arbor m at the inner end of a spindle M, the exposed end of the latter being provided with any approved form of handle or other convenient turning device m. Spindle M is grooved longitudinally at m to admit a plate-spring N, Whose free end carries a pawl n, adapted to engage with a segmental ratchet O, properly secured outside the case, the screw or pin n', that fastens said spring, serving as a stop to prevent said spindle being drawn too far forward. The spindle-handle m may turn within a pit p, cast in the face-plate Pof the case,

IOO

as seen in Fig. 5; but I prefer the arrangement represented in Fig. 8, in which illustration the spindle M is shown as passing through a central circular hole q of a dished plate Q, having an annular flange q', seated against a bearing p of the face-plate and held in place by a screw-threaded ring Q. p are screws that secure this plate to the window-sash R, the edge of the latter having a vert-ical groove r, suitably mortised to admit the case F and its cap S, which cap is pierced, as at s in Fig. 9, to receive the end of rock-shaft J.

Face-plate P is slotted horizontally at j? for the passage of the rounded portion t of a catch T, suitably pivoted to the rear of said plate, as seen in Fig. 2, the free end of this swinging catch being adapted to enter either one of the grooves d. of barrelD. The pivot of this catch has a pair of fiat facets, against either one of which the spring t bears, and thus holds said catch either in geai.` with the barrel or out of gear therewith.

t is a small projection wherewi th the catch T is swung either to the right or left, as occasion requires.

U U are duplex eccentricsor cams united by a pair of rounds or bars uu', one of which, as u', is grasped by the notch c of bolt C, while the other bar u has a hook V attached to it. i* is a sashcord attached to this hook, which cord or chain is passed over apulleyin the frame, and is then carried down within a suitable box or casing and furnished with a customary weight capable of balancing the sash in the usual manner. XV is ascrew that unites the cap S to the case F.

lVhen the various parts of my sash are in their normal positions, the upward pull of saslreord o causes the freely-suspended cams U U to bear against the guide B with sufficient pressure to force it into the groove r until it comes in contact with the edge plate Eef case F, as more clearly seen in Fig. Land the hook c, being engaged over the bar u', couples the sash R to said cams and through them to the sash-cord, the spring I preventing any accidental detachment of said hook. It is evident the sash is now suspended from the cord r, and as the hollow guide B is inserted in part within the groove a of the frame and in part within the groove i' of the sashit is apparent said sash is now incapable of being swung or turned in `either direction, but is free to be raised and lowered in the usual manner, the guide B confining said sash to a strict vertical path; but when it is desired to swing or turn the sash the small projection t is pushed to the right, so as to throw the catch Tout of gear with the grooved barrel D d', and the handle m is then turned in the proper direction to cause the cams K K to act against the levers L L', and thereby shift said barrel longitudinally until its head d strikes against the end of neck e, as seen in Fig. 3. This advance movement of the barlll rel forces the guide l entirely'out of the sash groove r and drives said guide into the framegroove u, as seen in Figs. 3 and 4. Consequently the sash is now supported wholly upon the barrel D, which serves as a pivot or bearing around which the collar c turns with perfect freedom, and when the sash has been turned in this manner until the desired angle is obtained the catch T is brought into service and by engaging withanother one of the barrel-grooves serves to lock the sash in position. Although the sash is now inclined or perfectly horizontal, if desired, it can be raised or lowered as before, but cannot aceidentally turn upon its pivots. To restore the sash to a vertical position, the catch T must first be intentionally disengaged from the grooved barrel D cl', as previously described, and then by retracting said barrel the guide B advances into the groove r and all the parts are restored to their normal places. This lateral sliding of the guide into the sash* groove is readily effected on account of the pressure exerted against said guide by the sash-weight pulling on the freelysuspended eccentrics U U', which have no connection with said guide, but simply bear against it. Previous to advancing the guide the spindle M is shifted forward as far as the pin 'a' will permit, which act disengagcs the pawl n from ratchet O and allows the rock-shaft .l to be turned back until the cams K K assume the position seen in Fig. l. Spindle M is then forcedmback, so as to enable the pawl n to re engage with the ratchet O, when the sash is again operated, as previously described. It is preferred to eorrugate the face of the edge plate E, as seen in Fig. 7, and also to corrugate the guide, thereby stiifening the latter and causing it to havea spring action within the mframe-guide. The dotted lines in this illustration show that the cams U U can bear against the concave portions of the corrugated guide.

In Figs. 2 and 4i considerable space has been IOO IIO

left between the bolt C and cams U U and between the latter and the sides of guide B, so as to prevent these parts being confused in the drawings; but said parts should be fit ted up quite snugly to each other, as indi cated by dotted lines in Fig. '7, so as to pre vent any material playA I claim as my invention-e l.
