amasar.

To all fui/0m it may concern:

Be it known that l, ERNEST MoColyNELL, a citizen ot the United States. residlng at Los ngeles,l in the county of Los Angeles and State oitl California, have invented a new and uset'ul Safety Swinging Window, ot' which the following is a. specification.

The main object of the present invent-ion is to provide a window in which the sash can be swung o1' tipped inwardly for cleaning, thereby obviating the necessity of the window washer reaching to the outside of the window or assuming a dangerous position while cleaning the window.

lhe invention is particularly applicable to the ordinary sliding windows or to set windows, and a further object of the invention is to provide in such windows a swinging lsash which is mounted on the niain sash in'such manner that the f ull strength' of the main sash is maintained and the operating of the sash in locking and opening and closing is not interfered with.

Another object of the invention is to provide a. swinging window of the above stated character in which the swinging sash is balanced to some extent on its pivotal supports.

Othel'l objects of the invention will appear hereinafter.

'lhe accompanying drawings illustrate an embodiment of the invention, and referring thereto:

Figure 1 is a front easing, showing the in .closed position. line c2-4r in Fig. 1. on line r3`af3 in Fig. 1. Fig. Il is a section on line .eL-x4 in Fig. 1. Fig. 5 is a view showing the application ol' the invention to a stationary window.

1 designates the casing or frame of a window of the sliding sash type, 2 and 3 being respectively the upper and lower sashes sliding inl said frame and guided vertically by stops f4, 5 and G, of the window frame. Each of the sashes 2 and 3 is formed as a rectangular frame having side bars 6', top bars 7, and bottom bar 8, and a swinging inner sash 9 is pivotally mounted in each ot" said sashes 2V and 3 to swing within the saine to either closed or open position. The pivots 10 for each sash are located opposite elevation of a Window window sashes therein Fig. 2 is a section on Fig. 3 is a section one another on opposite sides of the sash and extend horizontally a short distance Specification of Letters Patent. application med august 21, 1911.

above the bottom layer or bar of the sash. rlhe innerand outer sash frames are rabbeted and inclined on their adjoining faces, the shoulders 19, 19 of these rabbets and inclined faces 22, 22 otl the sash rails facing inwardly at all portions which are above the pivots, and facing outwardly at all points below the pivots,

joint against the weather pin is provided with a stud orextension 13 adapted to be projected into a socket or recess 14 in the side of the window A spring 15 surrounding said stud seated in a a shoulder 17 on the pivot pin 10 to press the pivot pin inwardly. A metallic tubular housing 18 is provided in the inner sash member around the bore 11 therein to serve asa guide for the pivot pin 10 and the end of said metallic housing 18 is beveled or formed with an incline as indicated at 20 to engage with a correspondingly inclined., fiange or projection 21 on the pivot p when the inner window sas Ais swung inwardly to open the same, the inclined portions 20 and 21 wlll engage with one another frame.

. projected into the oeking recess- 14. Pin 10- has a lug 10, engaging in a slot 16 in the housing for the pin, to hold the pin from turning.

Means are provided for normally locking the inner sashes in closed position in the outer sashes, said means consisting, for example, of catches 24 pivotally mounted at 25 and said catches being formed as arms adapted to engage beneath hooks or lugs 27 on the outer sash members. 24 are provided with handles 28 whereby they may be turned to open or close the. same and said handles Aalso serve as meansv of conveniently opening and closing the inner sashes.

Suitable means such as hooks or eyes 30, 31 may be provided on the respective inner AssIGNon or ONE-HALF To w. D.

Said catcheslocking and outer sashes for attachment o a chain such as indicated in dotted lines at 32 in FiO. 2.

indicates the usual counter-balance cords for the counter-weights for the respective sashes.

The top of the window trame is preterably provided with a pocket 34 for re ceiving the inner sash when it is raised so as to allow the inner sash to be raised sutliciently far to permit the outer sash when lowered to swing inwardly under the inner sash.

The operation is as follows: When it is desired to clean one of the sashes, for example, the inner sash, the said sash is moved to lowermost position at which time pivot pins 10 thereof come in line with the recesses 14 in the window casing. By then grasping the handles 28 the catches Q4 are moved out of engagement with their hasps or hooks 27 and the inner window sash is drawn inwardly causing it to tip on its pivots and torce the pivot pins inwardly'i'nto the locking recesses 14 by the operation of the inclines 20 and 21,- the inner sash memhermay thus be swung inwardly as far as desired for cleaning, or glazing, or other purposes, and while it is in this position the sash is locked against vertical movement obviating the risk of accident. 1f it is desired to hold the sash in tipped position this may be done by means of chain 32 attached to the hooks 30 and 31 as in Fig. 2. The inner member of the upper sash may be swung inwardly in a similar manner, the lower or inner sash being iirst pushed up out of the way and the upper outer sash being then drawn down and operated in the same manner as above described for the' inner sash.

In addition to the locking recesses 14 for retaining the sashes in lowered position other locking recesses 14 may he provided at higher levels, to enable the sash to be tipped and locked at other positions.

The invention may be applied to stationary windows, the sash of the window being a rectangular frame as above described, part of such frame being indicated at 35 in Fig. 4, and being set in position in the w indow l frame 36. In this case the pivot 10', may be formed on the stationary sash 36 and engaged in a metallic socket 37 on the swinging sash member 9.

By pivoting the inner sash frame above the bottom ot' said frame, I am enabled to provide the outer sash frame with the bottom bar or rail extending between the two side bars and bracing the same so as to retain the full strength of t-he rectangular frame. Moreover, this arrangement of the pivots balances the inner'sash to some extent, so that with a heavy window. the tipping and returning of the sash will he tacilitated. Y

lhat l claim is:

1. The combination of a window casing having recesses, an outer sash frame mounted to slide vertically in said casing, an inner sash frame mounted to swing, within said outer sash trame the pivots for said inner sash trame being slidably mounted and having portions adapted to project into said recesses in the window casing, and means on said inner sash frame for moving said pivots to projecting position when the inner sash frame is tippedtrom vertical position.

v. The combination ot a window casing having recesses, an outer sash frame mounted to slide vertically in said casing, an inner sash frame mounted to swing within said outer sash frame the pivots for said inner sash Jframe being slidably mounted and having portions adapted to project into said recesses in the window casing, and means on said inner sash frame for moving said pivots to projecting position when the inner sash frame is tipped from vertical position, and a spring acting on each of said pivots to remove the same from engagement with said recesses.

ln testimony whereof, I have hereunto set. my hand at Los Angeles, California this 16th day of August., 1911.

ERNEST MCC-ONNELL.
