William Edward Bartlett; Atlanta, Ga. Application October 27, 1950, ser'ia1 No.'-r9 2,507

This invention relates to -a combination Weatherstrip and sash balance which can be' applied to either old windows or. to new.

An object of. the invention is to provide an improved weather strip and sash balance which after the initial installation can be applied and removed as desired, thus permitting, the ready removal of the sash for the purpose'ofcleaning'the outside thereof, and theirreplac-ement' without the use of tools.

A further object of the invention is to provide a weather strip and sash balance coextensive in length with the depth of the sash'so thatv the weather is completely excluded;

A further object of thelinv'entionis to provide a device of thef character indicated" which will efiectively hold the sash at any elevatiorias desired.

A further object of the invention is to" provide a device of the character indicated which is economical in manufacture, easy to' ope'rate and highly efficient for the purposes intended."

Further objects will more particularly appear inthe course of the following detailed description.

The invention consists in the novel construction, arrangement and combinations of parts hereinafter more; particularly described and claimed. I

One sheet of drawings accompanies this specification aspart thereof, in which like reference characters indicatelike partsthroughout'. 1

I In the drawing:

v Figure l is a fragmentary view from the inside of a conventional double sash window frame with sash in position and showing the improved weather strip and. sash balance being applied to the lower sash.

Figure 2 is a fragmentary horizontal cross section taken through the window frame and a portion of a sash and the improved strip andsash balance; 7

c Figure 3 is a vertical cross section taken'on the line-3-3 of Figure 2; b 1 Figure 4 is a fragmentary-back plan viewof one end of the improved weather strip and sash balance; and ,7 1

Figure 5 is a fragmentary perspective'view of the hinged connectionfor thearticulated'portions of the weather strip and sash balance.

In the modern construction of homes there are numerous objections to the long prevalent form of sash controls comprising cords and weights which have proven objectionable for many years both by the additional space and expense required in the construction of the Window frames Claims. (01. '20.--52 .e) v

to provide. the necessary wells, for the weights, and also 'in the tendency of the? cords to break and .the necessity of. removing" normally permanent parts or the" window frame in "order to gain access to the weights for the replacement of the'cordsj I The result 'o'fth'is has been the development of frictional devices and the present invention is directed to an' 'improved" frictional slide device which can be interposed between the side edges ofthe' sash a'nfdj'a planar. surface'of the. window frame construction, thereby eliminating entirely the weight welLaswell as the sash cords; pulleys, et'c., and. providing in one device an efii'cient weather strip andbalance for the sash.

Such frictional devices have been heretofore proposed, but in view of the fact that the sash in a normal double sash window are each of a depth in excess of one-half of the total height of'the window openings by the width of the central rail, such frictional devices have necessarily been made shorter than the sash, thereby rendering them inefilcient to completely exclude wind and weather. If made of the full length of the sash, they could only beinstalled and removedby removal of the guide strips? on the a-ame.--

In accordance withthe present'invention the improved weather strip and sash balanceis-made in articulate form so that it can be bent and and thereby permit the insertion of such a weather strip and sash balance'of the full length or the sash} notwithstanding the 'fact' that the space available above the. sash is less than onehalf of the window opening.

Thev improved weather strip and sash weight of which the attached drawing discloses an efficient embodiment, comprises two frictional slide mern-bers. ll, each of whichis preferably beveled on its longitudinal edges as at 22 to prevent .'the entrance and adherence of paint in the normal painting of th'efwindolvwflandeach of which frictional stripsisipreferably formed, as illustratedof T-cross secti'on having a stem portion 3' adapted to mm a box-like base'member formed of channel cross section having its end portions inturned, as at 5 -5, to form such ends. The window sash S are initially formedlwith longitudinally extending grooves G, and preferably one base section, and its associated slide section, are substantially less'in length than the other base section and its associated slide. section, to

permit the introduction of the combinedmembers with a minimumflof flexing. However, the combined lengths of the two associated base sections and slide sections, are equal to the full length of the groove G and the sash s. Each of the frictional slide members l-l is coextensive in length with the respective base members 4-4 and these combined base and slide member-s, identified by the characters a and b (Figure are hingedly connected by a flat spring strip 1' adapted to lie flat against the web of the channel member forming the base 4 and to be secured by its ends to said web by the rivets 8. These rivets 8 are formed with heads 11 and with their opposite ends 9 of reduced diameter so that when the ends of the rivet are set, as at I0, they will rigidly associate the end of the spring strap 1 with the web of the channel base, as is well illustrated in Figure 3. The heads I I of the rivets 8 are slidable in countersunk holes l2 set in from the outer face of the slide members I, and the leg portion 3 of the slide member is normally forced away from the web of the channel base by compression springs M, a portion of which is seated in the countersunk holes l3 formed in the leg 3 of the slide strip and opening toward the inner face of the web of the channel base.

By reason of the structure thus far described, it will be apparent that the legs 3 of the frictional sections I will be slidable in and out of the channel base, being normally'forced outwardly by the compression springs M with the outward movement limited by the heads of the bolts 8.

.At the abutting ends of the friction strips [-4 are positioned small pieces of felt of substantially the thickness of the inturned end portions 55 of the channel base members, so as to provide a complete seal for the two frictional strip members when the same are brought into longitudinal alignment.

At one end of one section of each weather strip and sash balance is provided means for securing the channel base members against longitudinal movement with respect to the sash, comprising plate 20 adapted to bridge the edge of the sash and the adjacent end of the frictional slide, the plate 20 being bent backward upon itself, as at 2!, and thence downwardly, as at 22, within the channel base, having its end 23 extending through a slot in the web of the channel base to form an outwardly directed lug l8 projecting beyond the outer face of the web IS. The entire channel member is preferably disposed in a groove G formed in the side edge of the sash and in the base of this groove is driven a naillike member 5 having a head I! formed with a transverse notch l8.

When properly positioned in the groove G of the sash S, lug l8 engages the groove l8 and securely locks the channel base members against longitudinal movement with respect to the sash. From a consideration of Figure 3 it will be apparent that when it is desired to remove the weather strip and sashbalance, that pressure against the edge of plate 20 will force the channel member against the pressure of springs I 4 toward the frictional slide, thereby permitting the ing 18 to pass out of the slot T8, at which point alignment with the lower section and the entire 4 device inserted and withdrawn, as desired, without the removal of any of the covering strips from the window frame.

Where these improved weather strips and sash balances are used in new construction it will be apparent that the structure of the window frames F can be materially simplified and cheapened by eliminating the box structure on each side ordinarily provided to house the sash weights. However, the device can readily be used with frames of conventional structure, thereby eliminating the use of the cords and weights.

, While the present specification discloses a highly desirable embodiment of the invention, it will be apparent that other modifications will readily suggest themselves to those skilled in the art, but Within the scope of the present invention as claimed.

Having thus fully described my invention, I

claim:
