SASH LOOK AN'D LIFT.
SPECIFICATION forming part of Letters .Patent No. 598,797, dated. February 8, 1898. l Application filed October 14, 1896. Serial No. 608,869. on; model.)
To all whom it may concern.-
Be it known that I, PORTER MARSHALL, a citizen of the United States, residing at Fair Play, in the county of Polk and State of Mis souri, have invented a new and useful Sash. Lock and Lift, of which the following is a specification.
This invention relates to sash lifts and locks for windows, &c.; and the object in view is to provide, in connection with a sash-lift secured rigidly to the sash, a gravity-latch which is so fulcrumed upon the lift that it is instantly detachable, the latch being fulcrulned in a manner that will insure the engagement thereof with the keeper on the sill without the aid of a spring. The latch is so disposed with relation to the lift that it will be moved out of engagement with the keeper by means of the operators finger in the mere act of raising the sash.
Other objects and advantages of the invention will appear in the course of the ensuing description.
The invention consists in a combined sash lift and lock embodying novel features and details of construction and relation of parts, as hereinafter particularly set forth, illus trated in the drawings, and pointed out in claims.
In the accompanying drawings, Figure 1 is a perspective view of a portion of a sash and window-frame, showing the combined lift and lock applied thereto. Fig. 2 is avertical crosssection through the same. Fig. 3 is a detail perspective View of the latch. Fig. 4 is a vertical section through the upper portion of the sash-lift, showing the manner of fulcruming the latch. Fig. 5 is a plan view of the device. Fig. 6 is a detail perspective view of the keeper. .Fig. 7 is an enlarged vertical section through the sash-lift, showing the latch in elevation.
Similar numerals of reference designate corresponding parts in the several figures of the drawings.
l designates the main'body of the sash-lift, the upper portion 2 of which is curved and extends forwardly beyond the front face of the vertical portion of the lift to form a lip,
beneath which the operators finger may be placed lengthwise in the act of lifting the i to the sash and to the bottom rail sash. At the base of the lift 1 the latter is provided with a rectangular portion 3, which by means of an offset at is located in a plane back of the normal plane of the lift 1, and said portion 3 has Openings 5 for the reception of suitable fasteners by which the lift is secured shown in Figs. 1 and 2.
The sash-lift 1 is provided with a vertical slot 6 entirely through it,which extends downward into the portion 3 and upward into the lip 2. Within this slot is mounted a gravitylatoh 7, the same being pivotally suspended from its upper end. The latch 7 is provided at its upper extremity with a forwardly-projecting stud 8, which enters a socket 9, provided therefor in the lip 2 and forming a continuation of the slot 6. The latch is also provided at its upper end with laterally-projecting segmental ears 10, adapted to rest in recesses 11, formed in the lip 2 on Opposite sides of the slot 6 at its upper end portion, the recesses being of such depth that a flush surand said ears and stud contribute to form the fulcrum upon which the latch swings,- which fulcrum is in advance of the front face of the vertical portion of the lift.
The latch 7 at its lower or free end has a forwardly-projecting lip 13, which is adapted to engageunder the lips 14 of a keeper 15, secured to the window-sill. The latch is also provided at its lower end with a depending stop projection 16, which extends downward in rear of the base portion 3 of the lift and limits the forward movement of thelatch. The latch 7 is made enough thicker than the lift 1 to enable the same to normally project at the edge 17 in front of the sash-lift, so that as the Operators finger is placed lengthwise under the lift in the effort to raise the window the latch will be vibrated out of engagement with the keeper, thus permitting the sash to be raised. When the sash is lowered, upon removing the finger from the sash-lift the latch will move by gravity into engagement with the keeper and lock the sash. Should, however, the free inward movement thereof, as
of the lower end of the latch be arrested by the frictional engagement of the interlocking surfaces of the hook and the keeper or otherwise, pressure can be applied to the rear face of the latch near its upper end to force the hook into positive engagement with the keeper, as will be readily understood.
The combined sash lift and lock will ordi-' fiarily be applied to the bottom rail of a sash,
ment with the keeper is insured. ,By making the latch instantly detachablefroin thelift in the manner described the workof applying the device to a window-sash is greatly facilitated, as afterthe latch is removed the s ash-lift may be placed against thesurface of the sash-rail and its position outlined by a suitable instrument for guidingthe work man in'rnortising said rail to receive the deper. end with laterally-projecting ears which vice.
I It will be understood that the device issusceptible of changes in the form proportion,
and minor details of construction which may accordingly be resorted to without departing from the spirit or sacrificing anyof the advantages of this invention.
Having. thus described the invention what is claimed as new is 1. A sashrlift, comprising a vertical portion having, a forwardly-extending overhanging lip ,at its upper end and a perforated plate portion at its lower end, said vertical portion being slotted entirely through it, and the slot extending at its respective ends into the perforated plate portion and the overhanging lip, a gravity-latch of greater thickness than the lift mounted in said slot and pivoted at its upper end in the overhanging lip, the front'face of the latch normally projecting beyond the front face of the vertical portion of the lift, and said latch having at its lower enda forwardly-extendin g lip adapted to engage a keeper, the construction being such that pressure may be applied to either the rear or front face of the latch to positively engage itwith or disengage it from the keeper,
substantially as described.
2. The combination with a sash-lift having an overhanging lipfor the finger and also provided with ,a vertical slot,- theupper end QfxWhiCh;QXtendS into the overhanging lip and iscutaway upon opposite sides, to form recesses, said overhanging lip having also a socket formed therein communicating with said slot, of a gravity-latch mounted and movable in said slot and provided at its uprest inthesaid recesses and witha forwardlyextending stud which fits loosely in said socket, substantially as and for the purpose specified.
' In testimony thatI claim the foregoing as my own I; have hereto affixed my signature in the presence of two witnesses.
