Specification of Letters Patent.

' Application filed November 4, 1913. Serial No. 799,249.

of San Francisco, State of California, have invented certain new and useful Improvements in WVindows; and I do hereby declare the following to be a full, clear, and exact description of the said invention, such as will enable others skilled in the art to which it most clearly appertains to make, use, and practise the san a. I

This invention relates more particularly to windows in which the two sashes are so connected that they counterbalance the weight of each otl? er.

Among the objects of this invention are, to eliminate cords, pulleys and other counterbalancing'mechanisms from windows; to

so connect the two sashes of the window that they will counterbalance the weight of each other; to retain the desirable features of the sliding sash window, and add the advantages of reversible sashes, and a variety of sash positions possible only in pivoted sashes.

Other objects and advantages will appear as the descriptionprogresses.

In the drawing accompanying and forming part of the present specification, to which like reference characters have been applied a simple form ofputting this.invention into practice is shown.

I do not wish to be understood as confining this invention to the disclosures made in said drawing and description, as'many variations may be introduced, within the spirit of this invention as defined in the claims succeeding the said description.

In the drawings; Figure 1. is a front elevation in perspective from the outside of a window constructed in accordance with this invention with the upper sash in an inclined position. Fig. is a side elevation of the same, with the side of the frame removed on the line II-II to disclose the sashes in the closed position. Fig. 3. is a similar view of the same with both sashes in the full open position. The positions assumed by the sashes when registering in the open position is indicated in dotted lines in this figure. 'Fig. I. is a view similar to Fig. 2. illustrating the positions assumed by the sashes, when the lower sash is reversed.

Fig. 5.-is a similar view, with the upper sash reversed. Fig. 6. is a fragmentary detail view in cross section of the corner of the upper sash and the adjacent frame work, looking down at the level designated IV- IV, disclosing the spring pivot, and the relation of the connecting and swing arms to the sash and the frame. Fig. 7 is a similar view taken on the line V-, Fig. 1, illustrating the application and form of the switch plate. Fig. 8. is'a front elevation of the'switch plate as applied to the guiding slot. Fig. 9 is a front elevation fragmentary detail of a substitute for the switch plate and spring pivot for the top sash.

Fig. 10. is a fragmentary detail in front elevatlon of the sash lock as applied to the sash stile, and engaging a notched plate secured to the jamb stopg Fig. 11. is a from above of thesame.

In detail the construction illustrated in the drawings consists of a conventional win dow frame, that will vary with architectural conditions, and will be understood to include everything except the sashes, sash guides and other 'minor elements intimately combined with the sashes, in their combinative relation to the frame.

The window frame is provided with the grooves-1, l on both sides, extending from the sill 2, to the top plate 3. These slots are preferably formed in an inserted molding 4: of hard wood, metal or other suitable material, gained into the side jambs 5-5 of the window casing. This molding is preferred to slots grooved directly into the jambs; and further, the molding may be shimmed out to make up for any excess play between the window casing and the sashes, by inserting the shims 6.- ,For appearance the moldings are preferably the same width as the sashes are thick.

The sashes 7 and 8 are the usual rectangular, glazed frames, adapted when superimposed in the window casing to completely close the window opening. The necessary space between the sashes and the casing is sealed by the jamb stops 99 and 10 at the top and sides, alined with the stool 11, against which the sashes bear in the closed position, and from which they are adapted plan view to swing outward in opening.

Patented Sept. as, 1915.

The lower sash 7 is provided with the laterally extended spring-pivots, 1212 pref turned flanges 17, to normally hold the pivot in the extended position. The heads of the pivots extend into engagement with the grooves or slots 1, 1 Within which theyrnove freely up and down with the sash and exert aslight frictional pressure against the bottoms of the grooves for reasons that will be disclosed later.

To prevent the top of the lower sash falling outward it is provided with the spring bolts 18-18, similar in construction and similarly applied as described in connection with the spring pivots 12-12, a shoulder 14: engaging, a slot in the shell being provided to limit the extension of the pivot or the bolt as the case may be. i

The upper sash 8 and is provided as near the two upper corners aspraoticable with the spring pivots 19-19, similar to the pivots 12-12, and similarly engaging the grooves 1, 1. Thus constructed and installed either the upper or lower sash may beraised or lowered vertically, guided by its engagement with the grooves if the other'sash is swung out of its 4 path.

The two sashes are connected together by theconnecting arms 20-20, having each of their ends pivoted at points approximately one quarter of the length of'the sashes from the adjacent ends thereof. To permit the connecting arms to lie outside of the plane of the sashes, the extension brackets 21-21,

' and 22-22 are provided, to which the ends of the connecting arms are pivoted. The brackets 21-21 are gained into the stiles of the lower sash, at a point approximately one quarter of the distance from the top of the sash to the bottom thereof. The brackets 22 22 are gained into the stiles of the upper sash, at a point approximately one quarter of the distance from the bottom of the sash to the top thereof. The pivot tenters on the extensions on these two sets of brack ets extend beyond the outer plane of the sashes and aline vertically; whereby the connecting arms lie parallel with the plane of' the two sashes, when in the closed position; this is the preferred arrangement, but it is not arbitrary, as it may be varied without departing from the spirit of this invention.

To support the weight of the connected sashesand permit their various evolutions, the swinging arms 23-23 are provided on each side of the casing. The upper ends of these arms are pivoted at 24-24 to the adjustable plates 25-25 attached to the side jambs of the casing, near the top of the winis similar to the sash dow, preferably in line with the alined exuphold the weight, but the suspension system shown is preferred for many obvious reasons. The lower ends of these swinging arms 23-23 are pivoted" at 26-26, to the connecting 'arms preferably near the center thereof between the two end pivots where they join the extension brackets 21-21 and 22-22. ,The lower sash reverses more freely if the distance between the pivots 26-26 and 21-21 is slightly greater than that between the pivots 26-26 and 22-22, about one half an inch greater in actual practice. The exact locations of the pivots 24: of the upper ends of the swing arms are'determined when the sashes are in the closed position, then the adjustable plates 25-25 can be fixed permanently to the jambs, until further adjustment maybe found necessary owing to distortion. of the window frame or other causes. It is desirable to have the swinging arms 23-23 as long as practicable, better to support the sashes in such extreme positions as in Fig. 3, and to give a more favorable leverage in the manipulating of the sashes.

The invention operates substantially as "follows: To place the upper sash in the positionshown in Fig. 1, grasp the handle 27 and push the lower edge of the sash outward; this causes the upper edge of the sash confined by the engagement of the pivots 19-19 with the grooves to slide downward in the plane of the grooves. The lower sash beingconnected by the arms 20-20, and

fulcrumed on the pivots 26-26, of the swinging arms 23-23 is caused to rise simultaneously in ratio with the movement of the top sash. The weight of the upper and lower sashes being approximately. equal on both sides of the fulcrum mentioned, their respective weights are counterbalanced and either or both sashes will maintain the position into which they are forced by the operator.

The lower sash having its upper edg'eoonfined in the grootesby the spring. bolts 18-18, and its lower edge similarly confined by the engagement of the spring pivots 12-12 with the same grooves, is forced to rise and fall in a line parallel with the plane "of the grooves. To permit the two sashes within the casing, without at any period their evolutions projecting inward beyond the stops 99 and 10 and the stool 11, the switch plates 28-28 are provided as one desirable means. These plates comprise preferably, a single piece of sheet metal with the lateral extensions '2929 on opposite sides, adapted to be inserted into thegrooves 1-1, from the bottom of which they incline upwardly to the plane 30 of the plate that is surrounded on three sides by the upturned flange 31. These plates are secured in position by the screw 32 engaging the molding 4, and the nails 33-33 securing the edges of the extensions 29 to the bottoms of the grooves.

Just above the point where the lower sash going-up, would meet the upper sashcoming down, the switch plates are inserted. The spring pivots 1919 descending in the grooves strike theinclinedextensions 2929 up which they ride to the plane 30 of the plates, which clears the pivots from the grooves and permits them to travel laterally within the confines of the flange 31, removing ,the upper sash laterally from the path of the lower sash, which may be raised until stopped by the length of the connecting rod attached to the now vertical swinging. arms 23-23,- causing the sashes to assume the face to back position shown.

The same result may be accomplished by substituting a pivot X on the link X pivoted at X on the plate X gained in the sash stile X, as shown in Fig. 9, the slot X engaging the stop pin X", to limit the swing of the link X or in any other suitable manner.

It is obvious, since both sashes are-similarly secured within the window frame, and counterbalanced by attachment to each other at relatively equal points, that it is possible to cause the lower sash to follow the same evolutions that the upper sash is, capable of, if the top edge of the lower sash is freed from engagement with the grooves by the spring bolts 18-18. To so free the spring bolts from the grooves, the molding 4: is cut away on both sides of the'casing. Instead of making a gap it is preferable to notch the molding on both edges to form the incline planes 34-34, up which the bolts 18 will be caused to ride until they are de pressed in to the sash stile sufficiently to permit their engagement or disengagement with the grooves, for the purpose intended. This same result may be accomplished by substituting spring plungers for the spring bolts 18-18, thatwill project through the sash stile, for the withdrawal of the plungers from engagement with the grooves.

To reverse the lower sash, that is, to present the outside of the sash to the inside of the room, for washing, or other purposes; place about as shown in Fig. 1, release the spring bolts 18.18, then lift the lower edgeof the lower sash until'it is completely reversed, it will then have assumed the location within the window opening shown in Fig. 4.. To reverse the upper sash, follow the sameprocedure except that the upper edge of the upper sash is pulled downward, until its outer surface is presented within the room. See Fig. 5.

It is needless to explain that the other .sash describes correlative evolutions during the reversal of either sash, all of which are rendered sufiiciently obvious, by consulting the drawings. The sashes are restored to their normal positions by reversing the various actions described. One particularly desirable feature of this invention is the very convenient position, near the center of the window opening, that the sashes assume in the reversed position, facilitating washing, etc.

Because of the perfect counterbalancing of the sashes, and the novel arrangement of the leverage of the connecting and support ing arms, the upper sash can be made to assume any desired position by forcing the lower sash into the proper correlative position, and vice versa, that is to say, by rais ing the vlower sash, the upper sash can be forced into the positionshown in Fig. 1, or most of the various desired positions. These several positions are maintained even against strong wind resistance, vibration, or the like, because of the perfect balance of the sashes, assisted by the very slight friction exerted by the various spring pivots and bolts, frictionally pressing against the bottoms of the rooves that they engage.

Because of tl i ence of the upper and lower sashes, locking either will lock both; therefore it is preferable to apply the. locking means to the lower sash, because of its accessibility. Due desirable form of lock is shown, selected from the many forms available for the purpose. This form of lock includes the guide 35 screwed to the sash stile contiguous to the j amb stop. The slide bolt 36, provided with a conveniently shaped handle 37, is slidably guided in the guide 35. This bolt hasa head 38 adapted to engage the notches 39, in the plate 40 screwed to the jamb stop. To prevent the complete withdrawal, of the bolt the end of the head 38 is bent upward to stop against the end of the guide, when the bolt is withdrawn, from the notches 39.
