UNITED STATES EUGENE SMITH, or 'rooEtE, UTAH SASH-OORD rnsrnnna awn rnLcnUi r non wrnnow-sA-snns.

Application filed January 5,, 1920.

To all whom it may concern c it known that I, EUGENE SMITH, a citizen of the United States, residing at Tooele, in the county of 'looele and State of Utah, have invented certain new and useful Improvements in Sash-Cord Fasteners and Fulcrums for lVindow-Sashes, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to the art of win dow frames, wherein the inner sash and parting stripsor heads are removable, and particularly to improved means carried by the sash whereby the sash may be swiveled for reversing the sash, so that it can be re placed in a reversed position for cleaning the window pane or for glazing the sash.

As another object of the invention it is the aim. to provide means for attaching a sash cord to a sash whereby when the sash is swung inwardly it may swivel so that it can be reversed, and then replaced in the frame for. cleaning the outer face of the pane or. for reglazing the sash.

A further object is to provide a device to obviate the necessity of window cleaners sitting out on the sill of the window, or on supporting shelves, thereby avoiding endangering life.

A still further object of the invention is to provide device of this character pecially adapted for use in connection with sashes, which are not slidable but are fixedly arranged in the frame; said device being 1 designed to act as a fulcrum for the sash whei6by the be reversed as t s moved inwardly so that the outer face of the pane may be cleaned or the sash reglazed. In this case, it is the aim of the invention to provide a support for the device or fulcrum so that the sash may he swivelly reversed for the purposes intended.

-While the design and construction at pres ent illustrated and set forth is deemed preferahlm it isiobvious that as a result ofa reduction of the invention to a more practical form for commercial purposes, the in:

vention may be susceptible'to changes, and,

the right to these changes is claimed, provided they are comprehended within the scope of what is claimed. 7

The invention comprises further features and combination of parts, will he hereinafter set forth, shown in the drawings and claimedv Specification of Letters Patent.

Fig. 11 is a detail view showing how the bracket 82;. is attached. to thefsideof the window frame. 7

Referring more especially to thedrawings, l designates a conventional form of t o 7 of th inside sa h stop detachv ably fastened to the window frame, as

shown. In order to accomplish this resut to not mar the paint or other finish of the inner sash stop section 7, sleeves or bushings 10 are extended into or countersunk in said section. lhese sleeves or bushings 10 are provided with beads or rolls 11, against which the shoulders of the thumb screws 9 contact. it will be noted that the sleeves or bushings 10 are in diameter than the shanks of the thumb screws, in order to permit of an easy or screws through the sleeves or bushings. 11115 obvious that when the inner sash stop section 7 is detached, itis possible to remove or swing the lower sashinwardly of the room, so that it can be reversed.

The lower section 5 of the partmg str p is constructed of sheet metal, lJ-shaped in cross section, as shown clearly in Fig. 5, and the inner longitudinal edge portions of the side flanges of said parting strip are bent slightly toward each other as shown at 5 By this construction, it is possible to start and force the side flanges 5 of the parting strip section '5 into the groove 5 ot the Erame'rail, as shown clearly in Fig. 9. This method of attaching the parting st up section 5 is uniform throughout all the illustrations of the device. The lower end of the parting strip section 5 has a lateral ear or bent portion 5 When placlng the parting strip section 5 in position, the aperture or open1ng5 receives a dowel pin 5,

securely in place.

which is driven into the base of the window frame, adjacent the lower end of the groove 5 After placing the ear or lateral portion 5 in position, the parting strip section is moved toward and into engagement with the groove 5. In fact before inserting the parting strip sectionfi in the groove, its side flanges '5" are bent slightly toward each other, and when the parting strip section 5 is positioned home, the side flanges are brought-together, and owing to friction between these flanges and the side walls of the groove, the'partingi' strip section 5 is held all hen the parting strip section 5 is removed, the upper window sash can, be lowered, and then swung inwardly and reversed and placed in the position shown in Fig. 1, so that the outer face of the window pane may be cleaned or a new pane of glass inserted. strip section 5 maybe removed very easily, by inserting atool or sharp instrument or the likethrough any one of the'openings or apertures 5 .llhe instrument or other tool is passed through both flanges of the section The lower parting 5, and a pulling action is imparted on the tool, to pull the section 5 out of position.

Referring particularly to nigs. 1 and 2, each of the side rails of the upper and lower sashes and 15 is provided with a cylindri' cal depression a to receive the tubular cylinder Z). This tubular cylinder is provided with lateral ears 0 which receive screws d, in order to hold the cylinder in place. In fact the ears 0 are counter-sunk inthe'edge of the sash rail. A solid cylinder 6 is loosely guided in the cylinder b and has its inner end provided with an annular collar or flange g which is designed to contact with the inner end of the cylinder 6 to limit the outward movement of the solid cylinder 6, when the sash is reversed. In Figs. 1, 2, 3 and 4: the upper and lower sashes 14: and 15 are provided with the usual sash cord receiving grooves h and k to receive the sash cords m and a, when the upper and lower sashes are in'their proper position.

The outer end portion of the solid cylin der 6 is providedwith a transverse opening 9 to receive the lower end of the sash cord. The solid cylinder 6 has a threaded opening 72 extending axially of the cylinder. This opening p joins the opening Q and is designed to receive a threaded plug 3.

This plug 8 has'the usual slit or groove a in its oiiter end to receive a screw driver,

whereby the plug may be screwed home. A

' clamping plate 4) is placed through the threaded opening p, and in contact with the side of the end of the sash cord. The clamping plate o is concaved, so that its marginal edge will bury or sink into the sash cord, and act to clamp the cord in position in the opening q. The plugs at its inner end is concaved as shown at w to engage the clamping plate 4) so as to force it toward the sash cord. By this construction each sash cord is securely and detachably connected to itsrespective sash. At the present, the solid cylinder 0 is believed to be the most preferable form of connection for the sash cord, particularly in view of the fact that while Fig. 1 discloses the grooves it and 70 above the point or" connection of the sash cord, it is obvious that they may also be formed below the connection ot-thesash cord, as in Figs. 6, 7 and 8, whetherthe sash rail is thick or thin. In other words, withthc form of connection shown. in Figs. land 2, the sash cord receiving grooves may be formed above and below the connections of the sash cords, as the solid cylinder can be made very small in diameter, in comparison to the tubular sliding. cylinder which is shown in the other figures of the drawing.

hen it is desired to clean the outer faces of the panes of the upper and lower sashes, the inside stop section 7 and the parting strip section 5 are removed. The

lower sash is then moved in'wardl reversed, and placed in the position shown in Fig. 1. The upper sash is then pulled down and swung inwardly, reversed, and then disposed on the lower part of the window sill, as in Fig. 1. The sash cords engage around the opposite edges of the sash rails as will be obvious from an inspection of Fig. 1. The outer face of the panes of the upper and lower sashes may then be washed and the upper sash turned to assume its proper position and replaced in the frame, and then raised to its normal position. The lower sash is then pulled down from the upper position shown in Fig. 1 and reversed to its normal position and replaced in the window frame. However, before replacing the lower sash, the lower parting strip section 5 is replaced in the manner previously stated. After replacing the lower sash, the lower inside stop section 7 can be re-connected. The outer tubular cylinder Z) in Figs. 1 and 2 is provided with a U-shaped cut away portion .2 shown clearly in dotted lines in Fig. 2 to receive the sash cord when the sash is in its proper position in the frame.

in Figs. 3 and l the hollow outer cylinder 7) is provided with a single ear 0, which extends downwardly and receives a fastening screw (Z similar to that shown in Figs. 1 and 2. lllounted in the outer tubular cylinder Z2 shown in Figs. 3 and lis a hollow or tubular cylinder 6 the inner end of which is prowilled with an integral collar or shoulder The wall of the cylinder 0 has an opening 0 provided with an eye-let or sheet metal lining e. In this construction, the sash cord is passed through the eye-let or lining and is formed with a knot 91. to prevent the detachment of the cord. Also in this instance, the cylinder 6 is provided with the slot 32, which is shown in Fig. 8. This form of connecting the sash cord is particularly adapted for window sashes of the ordinar type, which have their rails very thin, and is also byfar a cheaper construction, by reason of the simple way "of attaching the sash cord to the inner cylinder by means of the knot. However, to use a knot for securing the cord to the inner cylinder it is necessary to have a larger cylinder than may be used in the construction shown in Fig. 1 or larger than the con struction of cylinder shown in 6, 7 and 8. The outer cylinder 5 in Figs. 3 and 4 provided with asemi-circular cut away portion or recess 5 which conforms to the construction of the sash cord receiving groove, so as to permit the cord to engage the eye-let covered opening of the, inner cylinder. l-lowevei', it is not possible to use sash cord receiving grooves below the cylinders 7) in Figs. 3 and l, by reason of the fact that the ear 0' extends downwardly.

the attached ends of the cords.

When the sashes are so positioned it is possible to reverse the sashes and then replace them temporarily in the frame, so that the outer faces of the panes of both sashes may be cleaned or the sashes glazed or reglazed from the interior of the room.

The reversing of the sashes is possible due to thesash cords 16and 17 being attached to their respective sashes by swivel or fulcrum connections, as indicated in the drawings, particularly in Figs. 6 and 7.

Each connection of a cord to a sash comprises inner and outer cylinders 18 and 19, y

the inner cylinder being rotatably mounted within the outer cylinder. Theouter cylinders of the fasteners of eachsash are counter-sunk or extended into the sash rails, as

shown, and are provided with diametrically.

opposite flanges 20 to receive fastening screws 21, to hold the outer casings 19 securely in fixed positions. In orderto counter-sink the outer cylinderslt), the side rails of the sash are drilled or bored out to form chambers, which are deep enough to permit the inner ends of the inner cylinders to errtend inwardly into the siderails beyond the inner ends of the outer cylinders 19. l-lowever, the inner ends of the inner cylinders 18 are provided with annular beads or shoulders 22 adapted to contact with the inner ends of the outer cylinders, to prevent the withdrawal of the inner cylinders entirely, when it is desired to remove the sash cords from their counter-sunk positionsin the side rails of the sash. The sash cords 16 are fastened to the walls of the outer ends of the inner cylinders by first passing the ends of the cords through openings or apertures of the inner cylinders, there being clamps 23 secured to the ends of the cords by means of clamping screws 24. The apertures or openings of the inner cylinders have their marginal edges bound or lined with headings or.

should the openings or, apertures not be lined.

In order that the sashes may be replaced in the frame after having been reversed so that the outer faces of the panes of glass may be cleaned, the outer edges of both side rails of the sashes are provided with grooves 26 and 27 above and below where the sash cords are attached to the sashes. It is obvione that when each sash is in its proper posi: lion, the sash cords engage the grooves 26, but when the sash is reversed, and replaced in the frame, the sash cords engage the grooves 2? which are then positioned above In order that the cords may lie in either set of grooves, diametrically opposite portions of the walls of the outer cylinders adjacent their outer ends are provided with semi-oil curing strip or stop 31..

cular recesses 28 for the reception. of the cords. f i r Referring to Figs. 6, 7 and 8 of the draw-. it ill be seen that either one or both thesashes may be moved inwardly of the room by first having detached the removable sections of the parting strips and inside sash stops. After having swung one or bothof the sashes inwardly of the room and then withdrawing the inner cylinders, the sashes may be moved swivelly, using the inner cylinders 18 as trunnions, until the outer faces of the panes face inwardly: lhe inner cylinders may then be. pushed inwardly causing the. cords to engage the grooves 2'7. The. sashes may then be replaced temporarily, after which the window cleaner or glazer may proceed to clean the pane, or glaze the same. i

In Fig. 10, agnon-slidable sash 30-is mounted in the window frame and held fixedly but i'omovably in position by the se- This strip or stop is fastened in. a similar mannerto the stops 0 5 previously described, preferably by we use of thumb screws heretofore referred to, though not necessarily. The sash 3G in Fig. 10 has its side rails provided with the cord attaching or fastening means which vebeen heretofore described. However,

llltlllS instance sash cords are not employed, and furthermore the attaching means, which may be so called in the presentinstance, simply constitutes a fulcruming means for the sash. The inner cylinders have their outer ends provided with segmental notches or slots 32 which as hereinafter set forth act tov straddle suita le supports to permit the sasii to be swivelly reversed when the sash stop: removed. It is to be understood that the inner and outer cylinders constitute trunnion means for slidable'window sashes as in Figs. 1 and 2 and 6 and 7, or when used on a single non-slidable sash as in Fig 10, and that the inner'cylinders are supplied with the notcheso'r slots so that the fulcruining trunnion means can be used in either case. in other words, the fulcrui'ning trunnion means constitutes an article of manufacture comprising the inner and outer cylinders telescopically and swivelly united with means on the inner end; of the inner cylinder to limit the inner cylinder in its out vard movement, in combination. with the sash cord attaching means and the segmental slots 7 or notches so thatthe"fulcruming trunnion means may be usedrin connection with slidable sashes wh ash cords may be attached to the inner cylinder, or on a non-slidable sash where the notches or slots enga e suitable supports, so that in either case the sashes may be moved inwardly and swivelly r versed after the stops have been removed.

Furthermore, referring to Fig. 10, it will be noted that there are brackets 33 connected to the side rails of the frame,'as indicated at 34 and '35. These brackets are in the form of metallic strips and their outer ends are provided with openings or apertures 36.

Suitable braces for the brackets 33 are proided, and each brace comprises a tubular lar section. W hen the brace :is employed,

the tubular section rests upon thesill of the window frame, as illustrated, while the outer end of the. rod section is fastened to the outer end of the bracket by means of a bolt or nut 40. The bolt may pass through any one of the openings or apertures 36 so. as to connect the brace to the bracket in different adjusted positions. Owing to the adjustable connection of the brace to the bracket and owing to the adjustable connections between the two sections of the brace, it is possible to hold the bracket indifferent adjusted positions relatively to the frame so that when the sash is moved inwardly of the room it may be held in different positions. Ordinarily the arch plate 35 is fastened to the window frame'as a fixture and when it is desired to right angle. ends of these brackets are inserted between the arch plates and the win dow frame after which the thumb screws 35 ar engaged through the arch plates and the it angle ends of the bracket. However, llu, b 'acket may be adjusted relatively to the vindow frame and in order to do this the humb screw 35 and the screws Bel may be renoved, the arch plates 35 replaced in a her or lower position on the side of the :i 1116 and the brackets may then be attached. When the arch plates are so adjusted it is obvious that the braces should be adjusted in order to accommodate the brackets in their different positions.

Obviously the brackets 33 may be used in connection with window sashes which are slid'able and which are carried on sash cords as well asin connection with non-slidable sashes. When-the brackets 33 are used in conn ction with 'slid'able sashes where the l1 cords are employed, the brackets will act to steadythe sashes when they are swivelly reversed even though thesash cords remain attached to the fulcruming trunnion means; As previously stated, when using the cylinders as shown in Fig. 10 there are no sash cords employed. It is. obvious that when the sash holding strip or stop 31 is removed, the window sash may be lifted inwardly of the room from the frame after which the inner cylinders 18 may be withdrawn. When the cylinders are so posidle the upperedge portions of the brackets 33 allowing the sash to slide inwardly of the room. When positioned suiiiciently in- 18 being held stationary by means of the notches 82. The inner cylinders act as trunnions, on which the outer cylinders (which are counter-sunk in the side rails of the sash) may rotate. After the sash has been 'swivelly reversed, it is possible to temporarily re place the sash so that the window cleaner.

may wash the outer face of the pane (which then faces inwardly of the room) or glaze the sash.

The outer cylinders 19 adjacent their outer ends are provided with semi'circular recesses 28 for the reception of the cords 16 when the inner cylinders are extended inwardly to their full counter sunk positions.
