Description

SSSSSSS ES Patented Feb. 10, 1925.
UNITED STATESY JOHN THOMAS MCCUNE, E DECATUR, MISSISSPPI.
SASH FASTENER.
Application ledwetober 3,-1922.
ried by the sash and cooperating with a` double series of notches in the sides of the window frame, whereby the sash may be held securely at any desired position, the dogs being retractable by movement of a. thumb piece toward the sash handle or lift to permit the sash to slide freely.
The special object of the invention is to arrange the thumb piece above the sash lift so that it may be operated by the thumb of the operator to release the dogs from their engagement, the foretinger engaging the 25 sash lift, the latter sustaining the entire weight and strain of lifting the sash after the dogs have been released.
To the attainment of the above objects and advantages, the invention consists in the details of construction and arrangement of parts to be hereinafter more fully described and claimed, and illustrated in thi` accom'- panying drawings, in which:
Figure 1 is a front elevation of ay window equipped with my device, a portion of the frame being in section;
Figure 2 is a vertical section on the line 2-2 of Figure 1;
Figure 8 is a vertical section on the line 3-3 of Figure 2, and
Figure 4 is a detail section on the line all of Figure 3.
Referring more particularly to the draw ings, the letter A designates a sash slidablc within the window frame B, which has the rear side of its face formed with a `series of ratchet like notches C, and recesses D. Mounted on the lower rail of the sash is the usual lift or handle E. i
In carrying out my invention, I `provide the opposite edges of the sash with casings 10, which are mortised therein as shown, and within each of which is pivoted at its upper end at 11, a depending dog 12, having an angular end 13, normally held .in outwardly projecting position by a leaf spring 14,
Serial No, 592,959.
,which engages against the rear edge ofthe dog and the opposed wall of the casinglt).
4:ner ends formed with slotsi, and which have their outer ends extending into the cas- 1ngs.10and terminating in flattened angu lar `extensions or arms 17, ywhich engage `.against the forward,r edges ofthe dogs.` ,Re-
cessed into the bottom sash rail isa housing 18, through the ends of which the shafts 15 entend, and this housing is located above the lift E. Bearings 15 are provided for the ends of the shaft.
The operating means consists of a thumb lever 19, formed of a plate 20, which is bent intermediate its ends to deline a sleeve 21, encircling the inner ends of the shafts 15, and further including a plate 22 which eX- tends across this sleeve and which engages within the slots 16 of the shafts 15. The plate 22 lies beneath the plate 2O and they are secured together by means of a rivet 23.
Assuming that the device has been constructed and installed as above described, it will be seen that by grasping the lift E with the forelinger and pressing on the thumb lever 19 with the thumb at the same time, the shaft 15 will be rocked owing to the engagement of the plate member 22 through the slots 16, and this rocking movement of the shafts 15 will cause the arms 17 at the ends thereof to swing the dogs 12 rearwardly so as to withdraw the angular ends 13 thereof into the casings 10. The sash will be easily raised and lowered by pulling on the sash lift E as it is freely slidable within the frame when the dogs are thus retracted. When pressure upon the thumb lever 19 is relieved, the springs 14 operate to project the dogs so that they will engage within the notches C or recesses D, as the case may be.. After the dogs have been retracted out of the recesses D, the sash may be raised as much as desired without it be ing necessary to press the thumb lever owing to the ratchet like formation of the notches C, but it is essential that the dogs be retracted before the sash can be returned to its lowered position. Owing to that fact, that the recesses D have their upper walls square instead of inclined, it is to be noted that the sash cannot be raised at all until the dogs are withdrawn from these recesses.
Hence the latch is locked when the dogs are in engagement with the recesses.
From the foregoing description and a study of the drawings it will he apparent that I have provided a simply constructed and consequently inexpensive and easily installed device tor holding or securing a slidable sash either in closed position or in a partially open position. As' the parts are so fev.' it is apparent that there is practically nothing to get out ot' order, so that the device should have a long lite and satisfactoriiy perform all of its functions.
Having thus described iny invention l claim:
rl`he combination with a Window sash having a lift secured rigidly thereto, and a Window iframe provided with a plurality ot' ratchet-like notches and recesses, of sash holding means consistingof a pair of casineens/i:
ings mounted in the sash, spring-pressed dogs pivoted within said casings and adapted to selectively engage said notches or said recesses, a pair ot' rock shafts having theirI outer ends formed with angular arms engaging said dogs, and a thumb lever secured rigidly to and connecting both of said shafts at their meeting inner ends, said thumb lever projecting out from the sash over the said lift, so that the thumb may press upon said iever to releasel the dogs, whereupon the sash may he raised hy the liorelinger engaging the lift, whereby all the strain and weight ot iaising the sash is borne by the sash lift.
In testimony, that l claim the foregoing as my own, l have hereto affixed my signature.
