INVENTO M 1? DEM/{CM ATTORNEY UNITED STATES PATENT OFFICE.

EDMUND H. LUNKEN, OF CINCINNATI, OHIO.

POCKET-WINDOW.

Application filed June 1?, 1919.

To all whom it may concern.

Be it known that I, EDMUND H. LUNKEN, a citizen of the United States, and a resident of the city of Cincinnati in the county of Hamilton and State of ()hio, have invented certain new and useful Improvements in Pocket lVindows, of which the following is a full, clear, and exact descrip tion, reference being had to the drawings accompanying this specification.

My invention relates to pocket windows of the type wherein the sashes slide under suitable counterba ancing weights and are adapted to be moved into a pocket adjacent the window opening.

The object of this invention broadly stated is to provide a double pocket window of the above type, wherein there are two sets of sashes, or two sashes side by side, and it is desired to economize in space to the greatest possible extent.

I have found that in a properly constructed window there is no absolute necessity for counterbalancing weights for both sides of the window provided the pull or" push exerted against the window is properly directed, and according to my invention this discovery is employed in the construction of a double pocket window where there is the necessity of great saving of lateral space. The principle of my invention is therefore to provide a window which has two sashes or more located side by side, with a narrow intervening separating strip, and counterbalance the said sashes on the outer side only and not at the meeting sides thereof. It is also, to provide for means to direct or force the operator to pull up on the windows at the sides opposite the counterbalancing weights.

.Vhile this invention is more particularly adapted for use with pocket windows, it is also adapted for use in the ordinary window. The use in pocket windows, is particularly advantageous because it readily enables me to provide a unit construction, adapted for shipment as a package, with the sash positioned and held in the pockets, all as specifically set forth in my Patent No. 1285269, dated November 19, 1918.

In the drawings,

Figure 1 is a vertical cross section taken through a double window constructed according to-my invention.

Specification of Letters Patent.

Patented Apr. 6, 1920.

Seria1 No. 304,828.

Fig. 2 is a detail horizontal section therethrough.

Fig. 3 is a detail prospective of a modified window pull Fig. 4 is a detail perspective of the roller, used for antifriction on the sides of the shades opposite the weights.

In the adaptation of inv invention shown in the drawings 1 indicate a unit double window construction, having a pocket at the upper end of the window opening. The construction has two sash weight boxes, having the outer boards 1 and the inner boards 2, both extending throughout the window opening and the pocket. There is a top board 3 to the pocket, a cap trim l for the window opening and a sill 5. Extending throughout the window opening and the pocket, through the center thereof is a dividing board 6, which serves as a stile for the sashes in both sections of the window. The inner boards 2 of the weight boxes serve as the outer stiles for the sashes, according to normal methods of construction and the pocket and weight boxes are closed by suitable boards.

There are pulleys 7 located in the upper end of the boards or stiles 2 and in the side boxes are the weights 8 and 9 for the upper and lower of both sets of sashes, which have proper weight cords for attachment to the outside upper end of the sashes.

It should be noted that by the words outside and inside in this specification is meant the portions away from the center of the window and adjacent the center of the window, rather than the indoor and outdoor portions of the window.

As shown there are two sashes in each section of the double window. the upper sash indicated at 10 and the lower sashes at 11. I prefer to countersink into the inner, upper edges of each sash an antifriction roller 12, which bears against the stile formed by the dividing board. This however, may be omitted since the window will operate without the antifriction device, although not so perfectly.

In order to direct or force the operator to impart the proper thrust or give the proper pull to the sashes, I provide lifts 13, for the lower sashes, which have inscribed thereon the words down on the outer side, and up on the inner side for each sash.

Thus the operator will lift the lower sashes on the side opposite the counterbalancing weight, thereby relieving the sashes of the necessity of a weight on the inner side, since the Weight is sufficient to relieve the strain throughout the entire window. The operator by lifting on the side opposite the weight really does no more than prevent the sash from canting' sidewise in the frame and wedging into a stationary position. The antifriction rollers also located on the sides opposite the weights tend to prevent this binding action.

' Upon the downward pull the tendency of the weights are to cant the sash toward the center of the window, and thus the pull is directed ,to the outer side of the sashes in the line of the counterbalancing weight.

In another modification of the device, I rely not, only upon the notice impressed upon the sash lifts, but provide special socket lifts (Fig. 3). The up lift 1 1 has a sloping base, and a horizontal top and the down lift 15 has a sloping top and a horizontal base. The operators fingers will slide out of the down lift, if he attempts to apply force thereto in lifting the sash, and vice versa with regard to the up lift, since only engagement that can be made by the fingers is with the horizontal portions of the two lifts.

It will be noted that there is provided for each sash both upper and lower, locking pins 15, which engage in sockets in the outer sash stiles. As noted in Fig. 1, the tendency of the sashes are to cant side'wise after they have been pulled down, due to the effect of the uneven counterbalancing, and thus the locking pins are a necessary portion of the combined structure, since they will hold the sashes in a level closed position. It isnot essential that the pins be spring pins, although they may be made with springsso as to automatically find their sockets when the sashes are properly positioned.

The entire unit, when made up is capable of being shipped as a package with the sashes counterbalanced and positioned in the pocket, as shown in my patent heretofore referred to.

There is no necessity for indications or special lifts for the upper sashes, when such are used, because the operator will fice to describe the non-pocket type, leaving entirely out of consideration the pocket por- 'tlOIl as now described. In a single window there would be but one weight box, if my invention were employed.

The narrowness of the double window, is very marked, and will provide the maximum opening and maximum light for a given space in a building. The width of two sash weight boxes is done away with altogether, and the whole structure is pleasing to the eye, and surprisingly easy in operation.

I do not wish to be limited to double or pocket windows.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is 7 1. In a window, the combination with a frame, of window sashes located on each side in said frame and sash weights for counterbalancing the sashes on the outside only, said sashes having lifts adapted to prevent the operator from applying pressure to the side adjacent the weights in lifting the window. 7 V

2. The combination with a window frame of a sash slidable therein, a counterbalancing weight and cord for one side only of the sash, and means for directing the operator in raising the sash to exert pressure on the oppositeside from the weight, and on lowering the sash to exert pressure 011 the same side as the weight, and locking pins on the side of the sash adjacent the EDMUND 1-1.
