Description

April 13, 1937. F. J. PLYM WINDOW CONSTRUCTION Filed sept. fr, 1954 Patented Apr. 13, 1937 WINDOW CONSTRUCTION Francis J. Plym, Niles, Mich., assigner to The Kawneer Company, Niles, Mich., a corporation of Michigan Application September '7, 1934, Serial No. 743,032

7 claims.

Among the objects of the present invention is to provide a novel double-hung metal window construction.

A further object is to provide a novel frame construction in which the sash weights, pulleys and cords, or the mechanism for raising and lowering the sashes are not positioned in vertical alignment with the sashes but are off-set therefrom. By thus positioning the operating mechanism, it in no way disturbs the weathering features of the window. l

Another object of the invention is the provision of a novel construction and arrangement of mechanism for operating the sliding sashes in a double-hung window.

A'still further object of the present invention is to provide a novel compact window construction having a minimum number of parts and affording a maximum area of transparency and light.

Yet another object of the present invention is the provision of a novel window construction which may be readily assembled and/or replaced and in which the parts are more readily accessible than those now in use.

A still further object is to provide a novel metallic window construction in which the frame and/or sash members are formed of extruded metal giving the structure unusual strength and stability.

Further objects are to provide a construction of maximum simplicity, efllciency, economy, and ease of assembly, operation and maintenance; and such further objects, advantages and capabilities as will later more fully appear and are inherently possessed thereby.

In the drawing:

Fig. 1 vis a view in side elevation of the interior of the window.

Fig. 2 is a broken view in'vertical cross section through the window taken in a plane represented by the line 2--2 `of Fig. 1. i

Fig. 3 is a view in horizontal cross section taken in a' plane represented by the line 3-3 of Fig. 1, but with the position of the window reversed.

Fig. 4 is a fragmentary view in side elevation of an alternate construction.

Fig. 5 is a view in vertical cross section of the construction disclosed in Fig. 4. t

Referring more particularly to the disclosure in the drawing, the embodiment selected to illustrate the invention comprises a window frame I formed preferably of extruded metal and having

side jambs

2, 2, head 'jamb 3A and sill 4. Any suitable means may be provided for retaining the /frame in the window opening. f

In the window frame are provided

slidable sash members

5 and 6. Each sash member is provided with side rails 1, the upper sash having a top ing channel or groove I2 for receiving a pane o! glass I3. In order to assemble or replace the glass, one of the side rails is made removable as by means oi' screws, bolts or the like, the pane being pushed into the grooves in the other rails. These other rails may be suitably connected as by soldering, welding or the like.

The side lrails 1 of the upper and

lower sashes

5 and 6, and the top rail 8 of thc upper sash and the bottom rail I I of the lower sash, are each provided with an outwardly facing groove or channel I4. The groove in the top rail 8 is adapted to receive a rib I5 formed on the head jamb 3, when the upper sash 5 is in closed position, while the groove in the bottom rail II is adapted to receive a rib I6 formed. on the sill 4, when the lower sash 6 is in its closed position. 'I'his provides an elcient weathering means for the top and bottom of the window.

Upon each side jamb is mounted a resilient strip of metal Il having a pair of ribs or guides I8 adapted to seat in the grooves I4 in the side rails l. These ribs have the double function of guiding the sashes in their sliding movement and of forming an efficient weathering means at the sides of the sashes. Due to the resiliency of the metal, the ribs I8 readily adjust and align themselves with the grooves or channels `in the sash members.

In order to readily raise or lower the sashes and to retain them in their adjusted position, the invention comprehends the provision in the form shown in Figs. 1to 3 inclusive, of a weight I9 connected to each sash. Each weight is connected to one end of a cable, cord or the like 20, with theother end 2| of the cable or cord connected to an eye bolt or other fastening means 22 mounted on a face of the sash. This cable or cord passes over a pulley 23 which is suitably mounted in the frame and which projects through the side jamb 2 and strip I'I. As clearly disclosed, the pulley, weight, cable or cord and the means for connecting the cable or cord to-the sash is off-set from the sash, or out of vertical alignment therewith. This construction insures no interference between the ribs I8 and sashes and permits these ribs I8 to extend for the com- Handles a are provided for aiding in ly, which when the sashes are in closed position,

interengage and afford complete insulation and weatering. A weather strip 26 of felt or other suita le material may also be provided in one or projection 21 on a removable plate or section 28 of the window frame. This section is suitably affixed tothe side jamb 2 by means of screws, bolts or the like 29, and when removed permits access to the weights and pulleys. The opposite side or face of the side jamb 2 is provided With a similar L-shaped projection 30, but which is shown as forming a part of the jamb rather than as a removable unit. However, it will be readily appreciated that this projection maybe made separately and suitably attached to the frame or side jamb. The base of these L-shaped projections or where they join the jamb proper, is cut away as at 3| to receive and retain the opposite ends of the iiexible strip l1, while the intermediate portion of this strip is formed to provide a parting stop 321 This strip is laterally removable from the window frame.

In Figs. 4 and 5 there is disclosed an alternate construction of window operating means in which the weights, pulleys and cords or cables are dispensed with. In this construction there is provided a helical screw or member 33 suitably positioned in the chamber formed by the L-shaped projections 21 and 3D. Each sash is provided with an eye bolt 34 in which is rotatably mounted a threaded nut 35, the latter rotating on the screw or member and carrying therewith .the sash.

A frame 36 is provided for carrying a screen or the like 31. 'Ihis frame is shown as suspended from one or more retaining members or lugs 38 and is provided with a groove 39 extending around the` four sides thereof. This groove is adapted to receive a bar or rod 40 for clamping and retaining the screen in position.

From the above description and the disclosure in the drawing, it will be readily apparent that the invention comprehends a novel window con-l struction and window operating means which in no way aiects the sliding operation of the sashes or the complete weathering between the side jambs and the sashes; This operating means is off-set from the vertical plane of the window. The invention further provides a frame and sashes therefor which afford a maximum amount of light and transparency.

Having thus disclosed the invention, I claim:
