Application filed September 10, 1919. Serial No. 322,989.

To all whom it may concern:

Be it known that I, J osEr-H CLEME T,

a subject of the King of Belgium, residing,

at Tournai, Belgium, have invented certain new and useful Improved Construction of Windows, of which the following is a specification.

This invention relates to the construction of buildings and has for its object to replace the wooden window frame and sash frames of sash windows by a reinforced concrete window frame in which slide two sash frames, also of reinforced concrete, so that construction of the window frame and of the sash frames is limited to the making of three concrete frames, each frame being Either concrete, or reinforced concrete as commonly known, may be used in my invention, but in the drawings for convenience the concrete is not shown as reinforced; and to avoid multiplicity of claims the term concrete therein should be interpreted as covering reinforced concrete as well.

The invention provides also a method of guiding sash frames by means of wooden guides or bars secured to the reinforced concrete frame of the window, which at the same time ensures easy. manipulation of the sash frames, close fitting thereof in the window frames. with, non-penetration of wind, andsolidity of construction.

The accompanying drawings show byway of example two methods of carrying out this invention. 2 A

Figures 1 and 2 are respectively a vertical section and a horizontal cross-section through a'window frame With sash frames of reinforced concrete.

Figure 3 is a section similar to that of Figure 2 showing a modified method of guiding the. sash frames.

With reference to the drawings, and more particularly to Figures 1 and 2, 1 is the window frame, the sill of which is moulded as for wooden frames, the styles and the upper rail being without moulding or groove; 2 and 3 arethe sash. frames, also made infone piece the uprights of which have throughout the whole of their height a groove as shown intended to engage woodenbars or ledges 4 4 secured to the styles of'thewindow frame 1. Two other wooden bars or

spacing ribs

4 and 4 also secured tothe styles of the window frame, complete the guiding of the "two sash frames frame 1.;

' relatively to each other and to the window frame.

For fixing the wooden bars P, 4 4?, 4

to the window frame 1, it is preferable to,

provide in the styles ofqthe latter, holes into which are introduced, after removal from the mould, wooden plugs 5to which.

the said bars are screwed '(see vFigure 3).

In order to prevent too sudden a contact. of cement with cement, one or more cushions 6 of rubber, cork or other suitablematerial PAT T "Omar. i

are embedded in the portions exposed to g shoulder 16, the recess 15. and shoulder 16 extending lengthwise of g the bottom face of the inner sash frame, the shoulder 12 of the sill'being engageable in the recess 15 ofthesash frame, and the shoulder of the sash frame being engageable in the recess 13 of the sill when the 'innervsash frameis in lowered or closed position for affording stop-weather connection between the sill and sash'frame. l

A strip of cushioning such as 6, may be secured in a recess on the shoulder 12 for cushioning the contact between the concrete bottom face andthe concrete Upper face of the portion 11 of the sill 'andpres venting passage of moisture.

It ispreferable to give to the two sash frames 2, 3 different heights, in order to make it possible to obtain at will complete closing of the. window bay, opening at the top or at the bottom only, or opening at the top and bottom simultaneously,-for the. purpose of ventilatingthe place.

The two sash frames can be connected togetherby cordswith'bahnce weights, but the two ,fram'eswill be preferably of prac tically 'equal' weight, in which case they:

will be connected together by a cord.-8 passing over pulleys arranged on a sup:

port 7 carried by 'therail of the window.

The arrangement described isa spe cial characteristic of the window of .the.presout invention, and consists in the fact that the two sliding frames are of, different height so that as a result of their relative positions there may be presented, for the passage of air, an opening at the top or at the bottom or at both the top and bottom of the window simultaneously. For example, the two frames may have the same weight and respective heights of 1% meters and 1 meter, and when the window is closed the larger frame3 (1-;- meters) may beat the bottom of the frame of the window, and the smaller frame 2 (1 meter) is at the top. This maybe obtained by giving to the smaller frame a heavier weight than to the larger one, or by well weighting the smaller frame 2 by means of heavier masses therein, or by relying upon counterweights. The two frames being thus balanced are connected by cables in such manner (as in Fig. 1) that when the one goes up the other comes down, and vice versa.

Suppose then that the large frame 3 be raised by a half meter, the smaller frame will descend about a half meter and there will be presented both at the top or at the bottom of the window an opening a half meter high. This double opening permits then ventilation at the top and bottom simultaneously. If one. continues to lift up the large frame until it reaches the top (its maximum path is 1 meter), the smaller frame will therefore travel 1 meter and it will leave at the bottom of the window an opening one half meter.

This arrangement is very advantageous for at will locating the point of the ventilating opening. If the structure is reversed, i. e., if when the opening of the window is completely closed, the smaller frame will beat the bottom, and one isable by the relative displacement of the two frames to obtain the ventilating opening at the top only or at the s top; and bottom simultaneously.

With reference more particularly to Figure 3, the uprights of the sash frames 2, 3 are not recessed laterally, but the upright of the inner frame 3 has a groove engaging a touch on the bar 4 while the'upright of the outer frame 2 has projectinga metal strip 9 partly embedded in the cement and sliding in a groove provided for the purpose in the corresponding style of the'window.

and show a considerable saving on the wooden frames. Reinforced concrete frames occupy less space, they are lighter in appearance, are not liable to deformation or loosening of the constituent elements, and are moreover incombustible. They can be made of any desired color, last indefinitely, do not require any attention, painting, or repairs.

Any desired mouldings or ornamentation can be obviously added to them. The metal skeleton forming the reinforcement may be in accordance with well known rules, or as desired.

What I claim as my invention and desire to secure by Letters Patent is 1. A sash window construction comprising a window frame of reinforced concrete and having a groove; two sash frames of reinforced concrete and adapted to slidein the window frames; guide strips secured to the uprights of the window frames and engaging grooves in the uprights of the inner sash frames, and metal guide strips projecting from the uprights of the outer sash frame and engaging the concrete of the grooves in the window frame.-

2. A sash window construction comprisinga window frame of reinforced concrete; two sash frames of reinforced concrete and adapted to slide in thewindow frame; guide strips secured to the uprights of the window frame and engaging grooves in the uprights of the inner, sash frames; and metal guide strips projecting from the outer face of the uprights-0f the outer sash frame and engag.

ing groovesv in the window frame.

3..A. sash window construction compris ing a window frame of reinforced concrete, two sash frames of reinforced concrete and adapted to slide in the. window frames, the three frames being made each in a single piece, guide strips secured to the" uprights of the window frames and engaginggrooves in vthe uprights of the sash frames, and cushion elementsinterposed between the sash frames and the window frame.

6.
