6 Claims.

This invention relates to new and useful improvements in a window construction.

The inventionhas for an object the arrangement of a window construction which is characterized by a means to constrain movement of the sash or sashes in the act of sliding and located either on the sash or sashes of the window and acting against the jamb, or on the jamb and acting against the sash or sashes.

It is a still further object of this invention to arrange a plurality of weather flanges on the sashes and acting in non-contacting tracks or guideways in the jamb, ortoarrange the flange or flanges on the jamb and acting in non-contacting tracks or guideways on the sash or sashes,

in a manner so that the flanges practically float within the guideways due tothe constraining a'otion accomplished by such means as rollers or the like. d a vIt is a still further object of this invention to arrange certain of said rollers in a manner to prevent transverse motion of the sash or sashes. Further, it is an object to arrange the rollersso as to prevent the flanges and tracks before mentioned from frictionally engaging each other, accomplishing instead a floating construction.

A still further object of this invention is to arrange the rollers when located uponthe jamb in a manner so that in all positions of the sash or sashes, the latter element or elements always contact therewith so as to make it possible to move the sashes through their entire path of motion and have the roller contacts at all times. For simplicity, in representation only one set of rollers at the central areas of the sashes is shown, whenthe latter elements are in their closed posi-' tions.

Furthermore as another object of this invention it is proposed to provide baille flanges on the 40 sash capable of dividing a compartment portion of the jambinto separate compartments, or baffle flanges on the jamb capable of dividing an air compartment in the sash or sashes into separate compartments so as to cause a number of reverses of air attempting to pass fromthe outside to the inside of the window or vice versa forming an efiicient seal.

As a still further object it is proposed to arrange the rollers to act against the baffle flanges mentioned in the previous paragraph for forming the floating arrangement of the weather flanges in their guideways.

It is further proposed to arrange the rollers to occasionally act against the edges of the bafiie flanges so as to limit lateral motion of the the provision of slight transverse movement of sashes whichwould cause the edges of the weather flanges to engage against the insides of their guideways and thus cause friction. Further, any combination of rollers may beused, that is, the rollers may be arranged on one of the sides of the bafile flanges only, or on both of the sides of the baiile flanges, or any combination of the sides and the edges of the baffie flanges.

It may be well to state here that while theinvention has been illustrated and described as particularly applied to metal windows, this is not intended as a limitation since it may be similarly applied to other types of windows such as wood or wood with metal coverings or the like. ,Another arrangement would be the applicationv of metallic sash strips upon the sides of wooden sashes in cases where the invention is to be applied to wooden windows. 7 Another one of the objects of this invention is the rollers so as to allow drawing together of inner and outer sashes in the closed positions of the latter elements in the action of fastening the sashes together as is conventional construeion.

Instead of rollers other means such as sliding surfaces may be used and the friction in such cases will be small since the contacting faces may be made small.

A still further object of this invention is the provision of a window construction which is of simple durable construction, dependable in use and efficient in action, and which can be manufactured and sold at a reasonable cost.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had tothe following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth. 95

In the accompanying drawings forming a material part of this disclosure:-

Fig. 3 is a fragmentary enlarged transverse sectional view taken on the line 3 3 of Fig. 1.

Fig. 4 is a fragmentary perspective View of a 1 portion of the baffle flange seen as though looking in the direction of the line 4-4 of Fig. 2.

Fig. 5 is a view similar to a portion of Fig 2, but illustrating a modified construction.

The window construction comprises a window jamb member 10 for mounting within masonry 11 or in any other manner upon a building. A weight box 12 is associated with the jamb 10 for receiving couunterweights 13 used in counterbalancing the sashes of the window. A division plate 14 within the weight box 12 serves to divide the'weight box into compartments so as to separate the paths of the weights. In Fig. 1 a window frame 15 is illustrated which is provided with a double hung window having'a-n outer sash 16 and an inner sash 17. While a double hung window has been disclosed, the invention can be equally applied to other types of windows and to windows that do not necessarily move in the vertical.

The sash members 16 and l7-are slidably arranged within the window frame so as to coact with the jambs 10 in their non-contacting sliding action. Groups of rollers 18 are shown in Fig. 1.

arranged within the jamb member at the central portions of the sashes when the sashes are in their closed positions for the purpose of accomplishing slidable supporting of the sashes. In Figs. .1 and 2 one embodiment of the invention has been disclosed, in which the groups of rollers 18 are arranged in the jamb.

A long compartment 19 is provided for each of the sashes and extends the full length of the jamb. This compartment is formed by the attachment of a metallic or other member upon the jamb and is provided with a front slot 20 extending its full length. A baflle flange 21 projects from the Window sash and engages into the compartment through the front slot 20. A bracket 22 35' isfixed in the longitudinal compartment 19 and serves to support the group of rollers 18 in a fashion so that the baiiie 21 is efliciently supported and constrained from transverse movement.

' The group of rollers 18 comprises an edge roller 23 rotatively mounted in the bracket 22 and lo-' cated so as to guide the edge of the baffle flange 21. The group 18 also includes a pair of opposite rollers 24 rotatively supported in the bracket 22 and engaging upon opposite-faces of the baflle flange 21 so as to slidably suppoit the latter element. A plurality of weather flanges 25 project from the sashes and engage without contacting in tracks or guideways '26 supported on the jamb 10. The rollers 24 should be so designed and positioned as to hold the weather flanges 25 from contacting with the sides of the guideways 26 while sliding, and the roller 23 should be so arranged as to make it impossible for the edges of the weather flanges 25 from engaging against the inside of the guideways 26. The weather flanges 25 together with the baflie flange 21 serve to form a practical weathertight arrangement even though the parts do not form contacting sliding fits in that they are arrangedto cause many reverses of the air in its travel.

For example, the passage of air may be traced from the outside at the point 27 into the guideway 26, then travel must reverse so asto discharge within the compartment 28 formed by one of the weather flanges 25 and the bafile 21.

Next the current must reverse again and pass through the longitudinal opening 20 and into the longitudinal compartment 19. Another reverse then must take place in the air to travel along the other side of the baiile flange 21 out through the longitudinal opening 20 and then be within the compartment 29 formed by the other of the weather flanges 25 and the baffle flange. The current then must continue into the guideway 26 and then reverse again out from the guideway.

By this time the travel of the air has been so resisted that it is practically nil. The sashes include panes of glasses 30 held in place by metallic binding strips 31 on opposite sides thereof. I

It is conventional construction to latch the sashes together when in the closed position by a fastener which has a cam surface tending to draw the sashes together. As shown on the drawings, this-fastener comprises a cup 32 pivotally supported to swing in the horizontal and having a cam surface 33 and being mounted upon one of the sashes. This cup is coactable with a hook element-34 fixed upon the other of the sashes in a'manner so that the cam may be turned to cause engagement with the hook and upon turning to draw the sashes together. A handle 35 projects from the member 32 to allow manual turning. From this brief description it is thought that the fastener can be recognized, since it is of conventional construction generally used. In order to allow-the window sashes tobe drawn together'by the fastener, certain resiliency must be provided in the vicinity of the group of rollers 18. For this purpose the baflie flange 21 is formed with cuts 36 located above and below the points of contact of the rollers 24 with the bafile flange 21. The small section of the bafile flange between the cuts 36 as shown in Fig. 4 necessarily has a large degree of flexibility and this allows flexing when the sashes are drawn together.

In Fig. 5 a modified construction of the invention has been disclosed in which the main difference is that the constraining mechanism is carried by the sash member instead of by the jamb member. In this figure the jamb is indicated by reference numeral 38 and is shown supported upon masonry 39. A weight box 40 is usedin conjunction with the jamb 38. A weight 41 is arranged within the weight box for counterbalancing the sash. The sash 42 is shown carrying a bracket 43 which supports rollers 44,- 45 and 46. A member 47 is attached upon the jamb 38 and has a projecting baffle flange 48. The member 47 also has weather flanges 49.

The sash member is provided with tracks or guideways 50 into which the weather flanges 49 co-act. ' I'he rollers 44 and 46 act against the opposite sides of the baiile flange 48 so as to slidably support the sash in a manner that the guideways 50 may not touch the weather flanges 49. The roller 45 is located along the edge of the baflie flange 48 for the purpose of preventing the sash from moving laterally in a manner in which the bases of the guideways 50 would engage against the edges of the weather flanges 49. The operation of this form is substantially identical with the preferred form as it relates to the passage of air from the front to the rear of the sash and as it regards the slidable supporting of the sash for the elimination of friction. a

From the description the operation will be clear, but it may be best to amplify upon the advantages of the invention. It should be noticed that the provision of the baffle flange forms a strong structure sothat it is possibleto use narrower sections for the sashes or the jambs without sacrificing strength. The introduction of the baflie plates serves to add additional passages for the air to cause a greater number ofreversesand add to the efliciency of the weather seal of the window. Furthermore, the provision of the bafiie flange which acts against the rollers to slidably guide the sash serves to separate the weathering function lie from the tracking function of the sash. By this it is meant that contacts between the weather flanges and the track or guideways therefor are not necessary.

The floating co-action eliminates sliding contacts of flat pieces. Furthermore, allowance is made for the movement of the sash due to expansion and contraction and inaccuracies in manufacturing. Tolerances are also provided for accommodating different sizes and improving the weather stripping of the window and incidentally eliminating rattling in that the rollers act firmly and unyieldingly against the baffle flange or the like. The rollers may be set at predetermined and accurate positions and then maintain the correct spacing of the sash relative to the jamb so that the weather flanges properly float within the guideways. The invention is not restricted to a single hung, double hung or any other type of window. Warping and inaccurate sizes of parts will not produce binding. The rollers are used in group and may be accurately assembled and machined in casting, or may be individually applied according to various designs.

Provision is made so that cooperating surfaces and cooperating edges and surfaces can maintain definite relation without touching, except at the roller points. This is accomplished by projecting the peripheries of the wheels slightly in advance of the surface or edge, or by directly contacting the rollers with the edge or surface. The provision of the bearing contact of the rollers upon the balile flanges serves to eliminate rattling of the sashes without the necessity of anti-rattling devices. Friction according to current practice is reduced by greater spacing of the weather flanges from the sides of the guideways and the consequent greater loose fitting. In spite of the greater spacing and looser fittings, rattling is not present and the weather proofing increased.

While I have illustrated and described my invention with some degree of particularity, I realize that in practice various alterations therein may be made. I therefore reserve the right and privilege of changing the form of the details of construction or otherwise altering the arrangement of the correlated parts without departing from the spirit or the scope of the appended claims.
