WINDOW-SASH-ADJUSTING DEVICE.

Specification of Letters Patent.

Patented Apr. 2, 1912.

Application filed September 15, 1910'. Serial No. 582,140.

. To all whom it may concern:

Be it known that we, ARTHUR G. LINDLEY and NORMAN F. DICKENS, citizens of the United States, both residing at Schenectady, in the county of Schenectady, State of New York, haveinvented certain new and useful Improvements in VVindow-Sash-Adjusting Devices, of which the following is a specification.

The present invention relates to window sash adjusting devices, and has for its object to improve their construction and operation, whereby the sashes may-be raised and lowered in the ordinary manner and also swung inwardly into the building for the purpose of safely and conveniently cleaning the outside of windows, or be removed entirely from the frame for repairing, etc., and this without interference in any case from the sash cords and weights of the counterbalancing means.

For a detailed-description of what we believe to be novel and our invention. attention is directed to the accompanying description and claims appended thereto.-

In the accompanying drawings is illustrated one of the embodiments of our invention, in which- Figure 1 is a vertical section of awindow frame fitted'with our invention, the sashes being shown in dotted lines; Fig. 2 is a similar view showing the upper and lower sashes swung into the building and resting on the stool cap and floor rests; Fig. 3 is an enlarged detail view showing one of the 1 lower corners of a sash and a hanging strip;

' Fig. 4 is a side view of the same; Fig. 5 is a detail view of the j amb and one of the removable stops and its securing means; Figs. 6 and 7 are detail views of the floor rests that support the inner ends of heavy sashes when swung into the building; and Fig. 8 shows the details of the safety hook.

In Figs. 1 and 2 of the drawings is shown a section of a window frame having sash stops 1, parting strips 1*, pulleys 2, sash cords 3 for the weights 3, sashes 4:, shown in dotted lines in Fig. 1 and full lines inFig. 2, a stool cap 5,and a lintel 6, all of which are or may be of usual construction.

As our invention contemplates the feature of swinging both the top. and bottom sashes inwardly into the building for the purpose of readily and safely cleaningthe outside of the window, repairing or removing them, pivoting means are provided therefor. l For convenience that of the lower sash will be referred to first. The sash is or I may be cut away or rabbeted on opposite sides at its lower corners as best shown in Fig. 3. Owing to the character of the view, only one side of the sash is shown, but it is to be understood that the opposite side is or may be similarly prepared. Mounted in this cut-away portion is a pivot-pin 7 which may be of any suitable construction, but for simplicity and reduced-cost a screw is used. To the lower end of the sash cord is attached a flexible connector?) that may be made of chain, cable or wire, or this connecting means-mayextend from the hanging strip to the weight, eliminating the sash cords, as best suits the requirements in any particular case. I In connecting the sash cord with the connector, and assuming for'illustration that the latter is made of wire, it is first bent and sharpened as at 10. Itis then inserted into the body of the cord and the outside tightly wrapped with fine wire as shown at 11. Owing to the fact that the joint between the cord and the connector gradually tapers it will readily pass-over the pulley 2 if necessary. The thin flexible v:

connector is used because the lack of space between the ordlnarv sash and wmdow jamb prevents the use of relatively heavy-"cord.

By using the thin connector and thin flat hanging. strips, we are enabled to equip windows of various kinds which are now in use, without cutting the frames or the sashes except at the bottom to receive the pivot pins. Of course if the sashes make a very tight fit they may be relieved slightly on,

the sides, but in no case is it necessary to cut or groove the frames, a task which is bothdiiiicult and expenslve.

The lower end of the connector 9 is se-V cured to a flat metal hanging strip 8 by suitable means, as for example, by, the clip 12 and the hook-likeformation of the con-,

nector' end. The clip may be riveted to the hanging strip or otherwise secured thereto,

The connector is passed through the eye of the clip and when the desired adjustment of length of sash cord, position of weight, etc., is obtained, the extra length 'is cut oif and the end turned up as as at 13 to form a supporting hook or secured in. some other suitable manner.

The hanging strip 8 may be made of any" suitable material ,having the necessary strength and rigidity with small cross-secthe sash. The seat for the pivot is below the mouth of the notch or slot to prevent accidental displacement of the parts. A pin 33 may also be mounted in the sash above the pin 7 and close to upper edge of the notch 14 to prevent accidental displacement when the sash is being raised preparatory to swinging it downward for cleaning or repairing. lVhen the sash is being turned down about the pivot 7, the pin 33 moves out of the opening of the notch 14. and into such a position that it does not interfere with the removal of the sash, if it is desired to take it out. With the pivot pins in place the sash can be raised and lowered at will and in the same manner as the ordinary window.

The inner sash stop 1, which is fastened to the frame, is made in two principal parts, the upper part being securely fastened in position while the lower part is made removable to permit swinging the sashes inwardly.

Unless means are provided to prevent it, the sash weights will suddenly raise the bottom of the sash as the top is swung away from the frame when they overba-lance the load on them. To prevent this a means is provided that locks or secures the sash weights .in their elevated positions while the sash is being swung on its pivots. This lock becomes effective before the inward swinging movement of the sash is commenced so as to prevent accidents which might take place with large heavy windows, and also insures a fixed and definite position for the sash when it is desired to clean the glass or make repairs. The locking device comprises a suitably shaped notch or slot 15 in the hanging strip 8 fitted with a safety hook 28 and cooperating with a pin, screw or equivalent device 16 located in the window jamb and therefore fixed in position. Between the pivot pin 7 and the locking pin 16 the hanging strip is or may be offset so as to readily engage said pins. These pins are out of vertical and horizontal alinement as is shown in Fig. 4.

To swing the lower sash inwardly the action is as follows, it being understood that both sides of the sash are alike and similarly supported: The lower portions of the sash stop are removed and the lower sash raised slightly to clear the stool cap 5, and at the same time moved inwardly until the looking pins '16 enter and are finally seated in their cooperating notches 15. As soon as this is done the weights on the cords are prevented from raising the sash. The top of the sash is then swung about pivot 7 away from its upright position and down ward into the building until it assumes the position shown in Fig. 2 and is resting on the stool cap 5, and its floor rests 25 if the weight of the sash makes it necessary to use said rests. This downward movement of the sash causes the safety hooks 28, which are pivotally mounted on the hanging strips 8, to cover the openings of the slots 15 when the lock pins 16 are engaged therein, preventing said lock pins escaping from their engaging slots until the sash is again raised to its normal position, when the hooks are automatically raised and held out of the path of the lock pins. This action is best seen in Fig. 8. When the sash is in normal position, the pin 29 mounted stationary in the sash prevents the hook from dropping by bearing on the projection 30. The opposite projection 31 on the safety hook is also now in the path of the pin 29, so that when sash is moved inward a short distance the hook is caused to move downward over the slot opening. Owing to the radius of the travel of the safety hook being much shorter than that of the sash about their respective pivots, the projection 31 on the safety hook drops out of the path of the pin 29 when the sash is swung in. The downward movement of the hook is arrested by its coming into engagement with the pin. 16. The projection 30, owing to its sufficient length, is still in the path of the pin 29 when the sash is dropped inward, which allows the pin to raise the hook as the sash is nearing its normal position. The end 32 is so shaped and is so located with respect to the pivot of the hook 28 that should the pin 16 press against it, there is no tendency to lift the hook but rather to hold it in position to close the opening of the notch. The weight of the free end of the sash acting through the stool cap as a fulcrum forces the pivot pins 7 into the upper end of the slots 14 where they are held by the weight of the sash and are prevented from slipping out by the inclined walls of the mouths of the slots; see Fig. 2. This same action causes the pins 16 to be firmly seated and held in the slots 15. At this particular time there is an upward thrust on those portions of the strips between the pins, which causes the lock pins 16 to act as supports for the sash when in horizontal position. To restore the sash the free end is raised to its normal position, the pins 16. disengaged and the stops remounted in place.

The arrangement of the pivot pins, hangupper sash inwardly it is necessary to first move the lower sash as described and then to remove the lower portions of the parting rods 1 which are made in two pieces for the purpose. The sash is then lowered until it strikes one or more stops 24. These are so set that when the sash engages them the mouth of notch 15 will be in position to receive the locking pins l6 carried by the jamb when the bottom of the sash is moved inward. After this the sash may be restored to normal operating conditions by raising it to an upright position and disengaging the locking pins by pressing the lower part of the sash back against the blind-stop.

Referring to Figs, 1 and. 3, it will be noted that the locking pins'16 and 16" in the window jamb extend into the path of the sashes and would limit their downward movement. To permit the sashes to be moved to the de sired position, a small piece is cut out of the lower corners of the sashes as shown in Fig. 3, the length of said cut-away portion being determined by the position of the pins and the desired travelof the sashes To swing the sashes inwardly it is necessary, as before stated, to remove the lower portion of the sash stops 1. To permit these stops to be quickly and easily removed without mar-ring the wood-work, specialsecuring means are provided. The adjacent ends 17 of the sections of the stops are connected by dowel pins 23. The jamb 18, Fig. 5, is counterbored atone or more places to receive screws 22 of suitable shape and size. Registering with each screw and fastened on the removable section 19 of the sash stop by a screw 21, is a spring clip 20 having two arms arranged to embrace the head of the screw 22 when forced, over it. These spring clips interlocking with the screws hold the stops against the lower sash, prevent lateral movement thereof, and form a simple yet efiective means for securing the stops. 7

It willbe noted from Fig. 2 that the sloping wall of the upper portion of the slot 14 inthe hanging strip 8 securely locks the sash in its horizontal position thereby preventing accidental removal. To remove the sash it is sufficiently raised at its free end to cause the pivot 7 to register with the mouth of the notch, after which a movement of the sash away from the frame will remove it. The weighted sash cords during this operation are held by the locking pins 16 or 16 In using this device on large windows the weight of which would be too great for the lock and pivot pins to support across the stool cap, floor rests are provided as shown at 25-Figs. 1, 2, 6 and 7, one on each side .tively unskilled workman.

of the sash. These supports are made preferably of light metal angle, a section of which is shown at 25 (Fig. 7 and are attached to the sash by screws 26 (Figs. 2, 6

and 7). In these views the sash is shown in horizontal position with supports dropped to rest on floor. When the sashes are restored to their upright position these supports, swinging on the screws 26, assume a vertical position, Fig. 1, the legs of the angle extending around and parallel with the inside corners of the sash, with the longer leg of the angle between the jamb and sash. To provide space for the shorter leg of the anglefwhen in this position, the sash is rabbeted as shown at 28Fig. 6. These supports are applied only to the lower sash, as the upper sash rests upon the lower when in horizontal position (Fig. 2). These supports are made of proper length to allow the stool cap to act as a fulcrum for the purpose mentioned, and yet relieve the pins of the extra weight by reaching the floor.

The chief advantage of our improved construction, aside from its simplicity and low first cost, resides in the fact that it can be applied to any weighted window wherein the sashes are moved up and down whether they are new or old, without cutting the window frame or jambs or modifying the sashes except by making small cuts in the lower corners thereof. This latter operation is so simple that it can be done by a rela- Our arrangement does not require any particularly nice fitting or adjusting, and hence can be installed in a short space of time and at small expense.
