SPECIFICATION forming part of Letters Patent No. 661,728, dated November 13, 1900.

Application filed May 13, 1899. Serial No. 7161695. (No model.)

To all whom t may concern: d', as shown in Fig. 4. Each roller C O' is Be it known that I, WILLIAM AGAR, a citiactuated by a coil-spring e, Fig. 6, fixed at zen of the United States, residing at Chicago, one end to the interior of the roller and at (Pullman,) in the county of Cook and State the other end to a liXed shaft e', on which the oflllinois, haveinvented anew and usefulImroller rotates and which in turn is supported 55 provementin Window-Adj ustments, ofwhich by brackets e2.

The adjustment is of peculiar value when Figs.2 and 6 show the two strips of 'tape as used in connection with a car-window andis formed from a single slotted piece, being 2Q illustrated in the accompanying drawings as united at e4. 7o applied to such a window. rlhe pulley-Stiles are connected by a slotted In the drawings, Figure l is a broken intecross-piece E, supplied with a sash-stop f for rior View of the side wall of a car supplied limiting the upward movement.

The sash is suspended by metallic provided with slots h to permit horizontal strips of tape d, flanking the grooves a and movement of the roller. passing about hollow spring-actuated rollers The spring-held guide-roller and attendant C C', located some distance above the sash, parts, after assembling, are inserted, barrel 95 and the sash balanced and guided and the foremost, into a socket in the vertical sash tension at the rollers C C counteracted by edge. The roller is preferably grooved, and spring-held guide-rollers D, located near the its groove forms practically a continuation of four corners of the sash. The tape strips d the sash-groove a. The bottom of the roller- 5o are conveniently secured to the sash by screws groove projects somewhat beyond the groove roo in the sash, however, and bears firmly against the metallic vertical guide c or c", as'the case may be. 'Thesash edge itself does not contact with the pulley-stile, as shown by the space at z', Fig. 5. Thus it appears, since the rollers are held under sufficient tension to prevent the sash contacting at any point on its vertical edges with the pulley-Stiles, that wedging of the sash is impossible. The tension of the guideroller spring, in fact, is suficient to overcome the force of the liftingrollers and cause the sash to remain in any desired position.

To lock the sash in its closed position and further aid in preventing the sash from sete tling down under a jolting action, such as is peculiar to railway-trains, a peculiarly-arranged spring-held locking device is provided.

This comprises a bell-crank Gr, pivotally secured in a casing G', setinto the bottom part of the sash and provided with a nearly-hori- Zonal arm 7c and a depending arm k', a rod joined at its inner end to the depending arm of the bell-crank and provided at its outer end with an angular part engaging' a notch on the guide-piece c', and a spring 7195 serving normally to hold the rod k2 in its lock-ing position. Upon inserting the fingers at thepart G' for the purpose of raising the sash they lirst engage the arm 7c of the bell-crank and unlock the sash, after which it is raised with extremely slight effort. At the desiredv position the hand-pressure on the bell-crank is released and the free end of the rod k2 bears against the track d, contributing a frictional force tending to prevent settlingof the sash. If desired, of course, a notch maj7 be provided at an elevated position for the end of the rod to enter, though this is ordinarily an unnecessary precaution.

The device is usefully applicable to vertically-sliding sashes in many situations'. Any desired number of guide-rollers may be provided, though there should be at least two at each vertical edge of the sash to prevent wedging.

Fig. 7 shows a barrel of elliptical eross-section, which may replace the one of circular cross-section where it is desired to use a narrow sash.

What I claim as new, and desire to secure by Let-ters. Patent, is` l l; The combination with two pulley-Stiles provided with projecting vertical guide-bars having smooth inner edges, a sash provided at its vertical edges with grooves receiving said guide-bars, and spring-held grooved rollers carried by said sash, the grooves whereof project slightly beyond the bottoms of said sash-grooves and bear throughout their traverses upon the smooth adjacent edges of said guide-bars, substantially as and for the purpose set forth.

' 2. The combination with two pulley-'Stiles provided with projecting vertical guide-bars, a sash provided att its vertical edges with grgoves receiving said guide-bars, draft-excluding lining of felt, or the like at said sashgrooves, contacting with said guide-bars, and rollers carried by said sash and projecting into said sash-grooves and bearing upon said guide-bars, substantially as and for the purpose set forth.

' 3. The combination with two pulley-Stiles, each provided with a central projecting guidebar and with stops parallel to and flanking said guide-bar, of a sash confined between said stops andv provided at its vertical edges with barrel-receiving sockets and grooves receiving said guide-bars, said vertical sash edges being outof contact with the pulleystiles, barrels D2 in said sockets provided with slots having outerends affording stops, rollercarrying blocks D in said barrels, springs confined between the blocks and the inner ends of the barrels and tending to force said blocks outward, rollers for said blocks having grooves projecting normally beyond the bottoms of the sash-grooves and bearing upon said' guide-bars,`and pins affording axes for the rollers and having their ends projecting beyond said blocks into said slots, whereby the outward movement of the blocks is limited when the sash is removed, substantially-as and for the purpose set forth.
