INVENTOR BYMJM ATTORNEY Patented Nov. 5, 1929 UNITED STATES PAT 'f DETACHALBLE sAsH Application filed December 28, 1927. Eerial No. 243,192.

This invention relates to means for hanging sliding window sash and like slidingly mounted members, whereby the sash may be opened and closed in the ordinary manner,

0r swung laterally for the purpose of conveniently Washing the window panes or for other purposes.

Another object of the invention is the provision of a weight balanced sash having novel means for attaching the sash cord or chain thereto so that the cord may be detached to release the sash, together with means for holding the cord against movement with respect to the window frame, whereby the cord will be retained in position to be again conveniently attached to the sash.

With the above and other objects in view, the invention further includes the following novel features and details of construction to behereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

- In the drawings s Figure 1 is an elevation showing a portion of a window with the invention applied.

Figure 2 is an enlarged fragmentary vertical section illustrating the means of attaching the sash cord to the sash with the parts in locked position. Figure 3 is a view similar to Figure 2 showing the parts in released position.

Figure 4 is an enlarged fragmentary sectional view taken on the line 44 of Figure 1.

Figure 5 is a similar view showing the sash hingedly supported and swung to an open position.

Figure 6 is a face View of a portion of a window frame showing the cord carried section of the attaching member.

Referring to the drawings in detail wherein like characters of reference denote corresponding parts, the reference character 10 indicates a window sash which is slidingly mounted in a frame 11. One side of this frame is provided with'a longitudinally extending groove 12 but the adjacent edge of the sash 10 does not enter this groove and the usual retaining and guide strips at this side of the frame may or may not be dispensed with. The sash however is of the slidingly mounted weight balanced type and for this purpose has attached. thereto one end of a cord or chain 13, the attaching means which forms a part of the present invention being of a character to permit of the cord 5 being readily attached to or detached from i the sash. For this purpose there is provided a sectional cord attaching member which comprises a section14 and asection 15'. The section 14 isslidable in the groove 12 of the window frame, while the sectionv 15 is positioned within a groove 16 provided in the adjacent stile of the sash 10.' The groove 16 may or may not be, but preferably is provided with a metal lining 17 within'which the section 15 has a sliding fit. A small section of thelsash is left in the groove 12 to provide a sea I I The section 15 is provided with spaced parallel inclined slots 18 which receive pins 0 19 extending transverselyof the groove 16, so that the section 15 may have a lateral sliding movement within the groove 16 and will be moved vertically during such sliding movement. Guide pins 20 have their inner ends secured to the sash 10 and are received within parallel inclined openings 21 provided in the section 15. The section 15 further includes a transversely U-shaped metallic member 22 within which is secured a block 23. This block is shaped asshown in Figures 2 and 3 of the drawings so that the side wallsof the member 22 extend beyond the outer longitudinal edge of the block for the major portion of their length, as indis5 cated at 24. When the sect-ions14 and 15 are connected in a manner to be explained, these extended portions 24 of the side walls will enter the groove 12 upon opposite sides of the section 14. i j so The section 14 comprises a hollow transversely rectangular casing which is provided with an opening 25. Extending across this opening is a pin 26 which is adapted to be engaged by a tongue 27 which extends from ,95 the adjacent face of the section 15. By reference to. Figure 3 ofthe drawings it will be seen that when the section 15 is moved outwardly and'downwardly, the tongue 27 will occupy a position above the pin 26. When the sash is raised, the weight (not shown) upon the Opposite end of the sash cord 13, will move the section 14 upwardly in accordance with the movement of the sash 10 so as to balance the sash. WVhen the. sash 10 is moved downward, engagement of the tongue 27 with the pin 26 will bring the section 14 and the adjacent portion of the sash cord 13 downward, as will be readily understood.

The purpose of the invention is to release the sash from the cord so thatthe sash may be swung inward, and in order to permit of this inward swingingmovement, the'opposite edge of the sash 10 may be hingedly or. otherwise mounted. Various means may be devised for this purpose, but it is preferred to employ the means shown and described in my copendingapplication. This means consists of a hinge which embodies a stationary hinge plate 27. This plate is preferably mortised within the window frame within a groove defined by

strips

28 and 29. The strip 29 is cut away to receive spaced lugs 30 which are carried by the plate 27 and this plate is provided with an opening 31. The opening 31 accommodates a plate 32 which is hingedly secured to the plate 27 means of a link 33 whose opposite ends receive pins 34 which extend through the lugs 30 of the plate27, and through lugs 35 which extend from the plate 32. The lugs 34 are also received within the cut-away portion of the strip 29.

The outer end of the plate 32 is provided with a flange 36 within which 'is provided a groove 37 and this groove "slidingly receives one edge of a plate 38 which is securedto the adjacent face'of the sash 10. The opposite edge of this plate engages within grooves 39 provided in the lugs 35, so that the'plate 38 is slidingly mounted with respect to the hinge plate 32. When the parts are in the position shown in Figure 4 of the drawings, the sash may be raised and lowered inthe ordinary manner. V

,The plate 38 carries a sleeve 40 which may or may not be. integral with the plate and which accommodates a locking bolt 41 and this bolt is provided with a finger piece 42 which extends through a slot 43 provided in the sash. The bolt -41 is adapted to enter an opening 44 provided in the plate 32, and when the bolt is engaged within this opening, the sash 10 will belocked to the hinge plate 32.

Normally, the parts are arranged as shown in Figure 4 of the drawings with the bolt 41 disengaged from the plate 32, so that the sash 10 may be raised or lowered. WVhen itis desired to swing the sash laterally upon the hinges, the finger pieces 42 of each hinge are slid inward or toward the adjacent ortion of the window frame, so that the bolt 41 will enter the opening'44. The sash cord attaching member is then operated to move the section 15 from the positionshown in Figure 2 to the position shown in Figure 3, so that this edge of the sash will be released and the sash may be swung to the position shown in Figure 5.

In order to manipulate the section 15 of the cord attaching member, the lining 17 of the groove 16 has extending therefromspaced aperturedcars 45. Pivotally mounted between .these cars upon a pivot pin 46 is a lever 47 This lever includes a finger piece and arm 48 which engages between spaced projections 49 provided in the upper end of the section 15. By swinging the finger piece 47 upward to the position shown in Figure 3 of the drawings, the section 15 will be moved inward and upward so as to disengage the tongue 27 from the pin 26. The section 15 is then free from the section 14 so that these sections may be moved independently of one another. v r

. In order to prevent the weight from drawing the sash cord 13 upward, the section 14 has pivotally mounted therein a dog 50.-

This dog has one of its-ends forced through an opening 51 provided in the casing of the section 14 so that it may enter. an opening 52 provided in a plate 53 which is secured within the bottom of the slot 12 of, the window frame. A spring 54 is utilized for forcing the dog through these openings, this spring engaging the lower end of the dog so that as soon as the opening 51 registers with the opening 52, the dog will'be forced inward. The opposite end of the dog however is arranged in the path of the tongue 27, so that when the parts are in the locked position shown in Figure 2, the d0g'50 will-be pre vented from entering the opening 52 and the section 14 which is attached to the cord may have free sliding movement within the slot 12. Before manipulating the finger piece 47 to release the cord, the sash is moved into position so as to permit the dog to enter the opening 52, so that when the sections are released, the spring 54 will force the dog into' the opening 52 and preventthe' sash cord from moving upward'under the influence of the sash weight; When the parts are in proper position to lock the sash to the hinges, the dog will be in proper position to enter the opening 52. i s

The lever 47 carries laterally spacedextensions 55 of a length to engage the frame 11 upon opposite sides of the slot 12, and this frame 11 is recessed upon each side of the slot as shown at 56. Therecesses 56 are so located as to permit the lever 47 to be operated to move the section 15 only when the section 14 is in proper position to be locked to the frame 11.
