Fild Dec. 16. 1927 Patented Dec. 30, 1930 HENRY WINTER, or BALTIMoRn, MARYLAND WINDOW-SASH FASTENER p Application :filed December 16, 1927. Serial No. 240,505.

This invention aims to provide novel means whereby a. window sash may be raised and lowered, and be turned on a horizontal axis to a tilted position. rlhe invention aims to provide novel means :tor mounting the sash on the carriers whereunto it is pivoted, and to provide novel means for holding the sash against tilting movement with respect to the carriers.

lt is within the province of the disclosure to improve generally and to enhance the utility ot devices of that type to which the invention appertains.

`With the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment or" the'invention herein disclosed may be made within the scope of what is claimed, without departing from the spirit ofthe invention.

ln the drawings:

Figure 1 shows in elevation a pair of window sashes wherein the device forming the subject matter of this application has been embodied.

Figure 2 is a vertical longitudinal section showing one of the sashes tilted into a partially open position.

Figure 3 is a section taken through the pivotal mounting of the sash.

Figure 4; is a sectional view showing the latch mechanism; and

Figure 5 is a. horizontal section taken through the latch mechanism and showing the latch mechanism in its relation to the sash on the carrier.

rllhe numeral 1 marks a window frame provided with the usual strips 2 which guide the sashes 3 for vertical right-line sliding movement. Since the construction is the same for the upper and lower sashes of the window, the description will proceed in the singular number so far as these sashes are concerned.

Metal bearing plates 4l are countersunk into the outer edges of the stiles of the sash 3 and are held in place by securing elements 5, such as screws which enter the sash. Behind the platesl, recesses 6 are formed in the stiles ofk the sash 3. The recesses 6 receive the heads 7 of-pivotelements 8,.such as rivets, the pivot elements 8 being mounted in the plates 4, and spring washers 9 being mounted on theV pivo-telements 8 between the heads Z and the bearing plates l.

Channel-shaped carriers 10, formed of metal, are mounted to reciprocate between the Y strips 2 on theA window frame 1. The carriers 10 are formed of spring metal, and include flanges 11 which diverge, the flanges bearing resiliently on the strips 2, to make a tight closure, as shown in Figure 5 of the drawings. T he flanges 11 have inwardly extended wings 12 which slide in Contact with the Awindow trame 1 and prevent the carriers 10 from wearing into the window, to any appreciable extent. Openings laiare formed in the carriers 10, and in the making of the openings 14, tongues 15 result, the tongues 15 being folded over on'ea'ch other, as shown in Figure 3 to form a secure place of mounting for the rivet or pivot elements 8, the rivet having a head 16 which engages the outermost ot the tongues T15'. Anchors/17 are secured to the bases of the carriers 10, and to the anchors 17 are connected the usual ieXible elements 18 that carry the sash weights, the flexible elements 18 being rove over pulleys 19 mounted in the window frame.

, The construction is such that the carriers may be slid up or down and be held bythe sash weights (not shown) in any position to which they have been raised or lowered. The sash 3 can be tilted into an open position, as shown in Figure 2 on .the pivotelements 8. The function ot the spring washers 9 is to draw the carrier 1() up against the edges of the sash 3 and afford atight joint through which the wind cannot iind its way.

Means is provided for holding the sashes 3 in alinement with the carriers 10, and with this end in view, box-like casings or supports 20 are let into the sash 3 at points near to the corners of the sash, the casings being secured to the sash, as shown at 21. rEhe casing 2O is provided on one side with a slotV 22, and on its opposite edge it has a slot 23. AlevergQ is tulcrumed intermediate its ends at 25 on the casing 2() and extends outwardly through the slot 22, the lever being provided at its outer end with a transverse finger-piece 26. The inner end of the lever 24 is pivoted at 25 to a link 28, the link being pivoted at 29 to the inner end of the latch 30 which is fulcrumed intermediate its end on the casing 20, as shown at 3l, the outer end of the latch 30 projecting through the slot 23 and terminating in a, transverse keeper 32. The bases of the car riers 10 have openings 33, through which the keepers 32 or the latches 30 are adapted to pass, the openings 33 having reduced eXtensions 34 into which the latches 30 move when they are in locked position. There are lugs 35 and 36 on the opposite ends of the latch 30 and these lugs 35 and 36 are oifset from each other slightly, lengthwise of the latch 30, as seen best in Figure 3 of the drawings. A spring tongue 37 is wound about a projection 38 on the casing 20 and includes an arm 39 that bears against one wall of the casing 20. IVhen the lever 211 is swung downwardly to the solid line position of Figure t the latch 30 swings outwardly7 through the slot Q3 and through the opening 33 in the carrier 10, the latch swinging down into the reduced eXtension 34 of the openings 33, and the keeper 32 engaging within the carrier l0, to draw the carrier up tightly against the sash 3 and against the edge of the casing 20 to prevent air from blowing through between the sash 3 and the carrier 10. IVhen the latch 30 is in the locked position of Figure t the spring 37 bears on the lug 35 and tends to hold the latch in the position specified when, however, the latch 3() is swung back into the casing 20 into the unlocked position shown in broken lines in Fig. 4 of the drawings, then the spring 37 bears on the lug 36 of the latch 30 and tends to hold the latch in the retracted position specied. The carriers 10 are pulled against the edges of the sash 3 at all four corners of the sash, and not only is the sash securely held against swinging into an open position on the pivot elements 8, with respect to the carriers 10, but, at the same time the carriers are pulled tightly against the edges of the sash and the passage of cold air between the carriers and the edges ofthe sash is prevented.

IVhat is claimed is l. In a device of the class described, a support, a latch bolt fulcrumed intermediate its ends on the support, spaced lugs on the latch bolt, a spring mounted on the support and engageable with the lugs one at a time, to hold the latch bolt in advanced and locked position and in retracted and unlocked position, and means for operating the latch bolt, said means comprising a lever fulcrumed intermediate its ends on the support, and a link pivotally connected with the inner end of the latch bolt and with the inner end of the lever.

2. In a device of the class described, a support, a latch bolt fulcrumed intermediate its HENRY IVIN'IER.
