Bnventor Cil Patented Oct. 8, 1935 UNITED STATES PATENT OFFICE 2 Claims.

This invention relates to an improvement in windows and more particularly to the mounting of window sash in the window casings and control of the sash.

Since storm sash and screen sash are usually mounted interchangeably in Window casings, the changing depending upon cold or hot seasons, it is an important feature to provide such an arrangement of parts that these changes may be conveniently made.

By use of the herein described invention the mounting of sash in window casings or removal therefrom may bev readily and safely accomplished from the inside of a building, no outside work being required, this feature being of great advantage for use in tall buildings since the work may be performed speedily, conveniently and accidental injuries may be avoided.

The invention consists of the new and useful lconstruction, combination and arrangement of parts as described herein and claimed, and as shown in the drawings, it being understood that changes may be made in form, size, proportion of parts and minor details, said changes being within the scope of the invention as claimed.

In the accompanying drawings, Fig. 1 is a broken away detail view showing the inner side of a detachable storm or screen sash provided with an arcuate guide-plate.

Fig. 2 is a detail View showing a roller bracket attached to the blind-stop of a window casing, the roller being in section.

Fig. 3 shows the outer side of a window casing, and windows therein.

Fig. 4 shows a window casing and storm sash in longitudinal section to illustrate the operation of hoisting the sash into operative position from the inner part of a building.

Fig. 5 is an enlarged detail relating to Fig. 4, showing the upper part of the sash in its inclined position, the fastening devices being in section.

Fig. 6 is a View in detail relating to Fig. 5, showing a socket-plate mounted on the vertical blind-stop of the window casing.

Fig. 7 is a View of the socket-plate and blindstop taken at right-angles to the View shown in Fig. 6.

Fig. 8 is a detail showing the lower part of a storm sash in section to clearly show a catchmember and a second catch-member mounted thereon.

Fig. 9 is a plan view showing a part of the base of a window casing provided with a hinge and a latch pvotally mounted on the hinge,

' described in connection with the base I0 and blind-stop I I of a window casing I2, and a detachable storm sash I3, and pair of windows m.

While a detachable storm sash is shown in the drawings, it will be understood that the invention includes a detachable screen sash, the 10 parts to be described for the control and mounting being the same so that one kind of sash may be substituted for the other conveniently whenever required. l

In order that the objects first mentioned may b`e attained I provide a pair of downwardly projecting, rectilinear socket-plates I4, these being secured upon the inner sides of the casing near the top thereof, said sockets preferably being 2 mounted upon theblind-stops II of the casing.

Each socket-plate I4 is provided with a. slot I5 and includes a buffer-flange a disposed at right-angles to its base.

Numerals I6 indicate a pair of opposed, up- 2 wardly projecting, arcuate guide-plates which are secured to the upper end of the detachable sash I3, each arcuate guide-plate being provided with a slot I'I.

Numeral I8 (Fig. 2) indicates la roller-bracket 30 which is secured to the upper part of the casing upon the blind-stop II, said roller-bracket being used for supporting a hoisting-strand I9 for use when the sash is lifted to operative position or lowered therefrom.

Numeral 20 indicates a catch-member provided with a horizontal, apertured projection b, best shown in Figs. 8 and 9 of the drawings and at 2I is indicated a second catch-member, these parts being mounted on the lower end of the 4 sash upon the inner side thereof.

As thus described the hoisting of a window sash into operative position from Within a building may be conveniently accomplished. The strand I9 is secured to the apertured projection 4 b at the lower end of the sash and engages in a staple 22 at top of the sash, and the strand engages the roller of the bracket I8 so that the sash may be elevated or lowered by manual use of said strand.

. 50 When moved through the casing to be fitted engage in the apertures or slots I5 and Il of the 55 respective sockets and guide-plates the sash may be supported by the casing, and it is obvious that the guide-plates I6 will readily slide downward -from the sockets for removal of the sash after the keepers 23 have been removed. Y

The operation of parts last mentioned will be readily understood by an inspection of Fig. 5 of the drawings, and it will be seen that on account of the arcuate form of the guide-plate I6 the storm sash I3 may be swung outwardly of the casing, this being of advantage to provide Ventilation of a buil-ding.

Since these members I6 are of arcuate form they may swing around the rectilinear socketplates while the sash has a swinging movement to closed or open positions, the slots which are traversed by the keepers 23 also permitting the swinging movements of the window sash.

Numeral 24 (Figs. 3, 9) indicates a hinge which is mounted on the base I!! of the window casing, and pivotally mounted at 25 upon one of the wings of the hinge 24 is a latch 25 having a terminal part bent at right-angles to provide a second latch-member 2 having a notch 28 opening on its edge.

After the sash has been swung to closed position within the casing as shown in Fig. 9, the latch 26 may be swung downwardly into the catch for locking the sash in closed position, the

latch 26, for this purpose swinging from its pivot on a wing of the hinge 24.

In order to maintain a storm sash I3 in open position the latch 26 is also used and may be swung outwardly to the position shown in broken lines in Fig. 9, the notch 23 of the second latch 21 of said latch 2E receiving the second catch 2I of the sash.

The latch 25 may have swinging movements in a plane parallel with the longitudinal axis of the hinge for engaging the catch 20, and may be swung at right-angles to said axis of said hinge outwardly of the window casing to; permit said notch 28 to receive the second catch 2| of the sash, said latch 26 having two movements, one being parallel with the sash I3, and the other movement being transverse to said sash to cause the second latch 21 to engage the second catch 2|.

Since screen frames are generally tted into the casing to remain in stationary position the use of keepers 23 will not be required, but Will of course be required in all instances when the sash is disposed in inclined position.

I claim as my invention,-

l. In a hinge for use with a sash and a stationary frame, a slotted socket-plate adapted to be secured to the frame, a guide-plate adapted to be secured' to the sash and having a slotted arcuate part, said sash being adapted to be tted into the frame with the slot of said arcuate part in register with the slot of the socket-plate, a pivot disposed at approximately right-angles to the face of the guide-plate engaging in said slots and adapted to be mounted in the sash for supporting and permitting a swinging movement of said sash relative to the frame.

2. In a hinge for use with a sash and a stationary frame, a rectilinear, vertically disposed socket-plate adapted to be secured to the frame, a guide-plate disposed parallel with the sash and adapted tc be secured thereto and having a slotted arcuate terminal part, said sash being adapted to be fitted into the frame with the slot of said arcuate terminal part in register with the slot of the socket-plate, a pivot disposed in said slots and adapted to be secured to the sash for supporting t said sash, whereby the arcuate part of the guideplate may move around the lower end of the socket-plate to permit a swinging movement of said sash relative to the frame.
