With reference more particularly to Figures 1 to 16, inclusive, there is disclosed an awning type window embodying my invention as associated with a wooden window frame, the latter being designated by the numeral I. In the present instance three sashes 2, 3 and 4, respectively, are employed. The manner in which these sashes are mounted and are operated will now be described in detail.
Mounted for vertical slidable movement in a suitable guide channel 5 formed in each side of the window frame I is the metal actuating bar 6. 'Ihere are .two of such bars, one in each side of the window frame for cooperation with the respective ends of the several sashes.
Plate-like members I are disposed across the slidable actuating bar and are secured to the frame I by suitable fasteners 8. These platelike members not only serve to retain the actuating bar in its channel, but also provide a means for securing one portion of the hinge unit that is associated at the respective sides of each sash.
Each hinge unit includes a link 9 that is pivotally connected at its lower end, as at I0 to the respective plate-like members. The upper end of the link 9 is pivotally connected to the leg member I I that is fixedly secured to the side edge of each sash. These members II constitu-te the sole means for supporting the sashes.
Each leg member I I is formed with an offset arm portion I2 at its upper end, as is more clearly illustrated in Figures 2, 3, 4, 9 and 15, respectively.
The leg members that are associated with the uppermost sash 2 have their oilfset arm portions pivotally connected to the upper portions of the slidable actuating bar 6 as indicated at I3.
The hinge unit that is associated with the central sash 3 includes a bracket I4, havinga raised central portion to which the upper end of the offset arm I2 is pivotally connected as at I5. The end portions of this particular bracket are formed with longitudinal slots indicated at I6 and serrations I1 are formed in the outer face of the slotted portions of the bracket to coact with the edges of the lugs I8. Screws I9 extend through the lugs I8 and the respective slots I6 and are 4 threaded into suitable openings provided therefor in the slidable bar 6.
This construction provides a means for adjustably securing the hinge unit associated with each side of the central sash 3 to the actuating bar, thereby providing for a tight fit between the several sashes when the latter are in a fully closed position.
The bracket forming a part of the hinge unit that is associated with the lower sash 4 is shown at 20 in Figure 14 of the drawings and this particular bracket has its raised intermediate portion 2I formed with a keyhole slot 22. An arcuate lug or shoulder 23 is formed on ythe raised portion 2I for a purpose to be presently described.
The end portions of the bracket 28 are also formed with longitudinal slots 24 similar to the slots I6 formed in the end portions of the brackets I4, and transverse serrations 25 are formed in the outer face of the slotted end portions of the bracket 20.
Channel shaped lugs 26, similar to the lugs I8 have their edges coacting with the serrations 25 in the manner as clearly illustrated in Figures 9, 11 and 12 and accommodate the screws 21 that extend through the slots 24 and screw into threaded openings provided therefor in the slidable actuating bar 6. In this manner, the hinge unit associated with the lower sash 4 is also adjustably connected to the slidable actuating bar.
The arm I2 of the hinge unit, that is carried by the lower sash 4, is formed at its upper end with the flanged finger portion 28 that is adapted to cooperate with the shoulder 23, in the manner to be presently described.
A fiat faced pin 29 extends laterally from the arm I2 adjacent the flanged finger portion 28 and this pin is operable in the keyhole slot '22 formed in the raised intermediate portion-2| of the bracket 20, in a manner also to be hereinafter explained.
The aforementioned hinge unit construction as associated with the lower sash provides for the delayed opening of the lower sash, which is a salient feature of the present invention.
The central or intermediate sash 3 is employed to constitute the operator for opening and closing the several sashes, although I do not wish to limit myself to this arrangement as the top sashmay serve as the operator or an entirely independent operator may be employed to effect the operation of lthe actuating bar.
A handle 30 is associated with the lower rail of the central operating sash and this handle may also serve as a closure for cooperation with a suitable keeper 3| carried by the top rail of the lower sash 4 for locking these two sashes together when the sashes are in a fully closed position.
Forming an important part of the present invention is the locking means provided for the upper sash 2. To this end, thereis mounted on the frame I a bracket 32. A hook-like fastener 33 is pivotally mounted on the bracket 32, for cooperation with the keeper 34 that is secured on the adjacent side edge of the upper sash 2.
A lip 35 extends laterally from the pivoted hook-like fastener for cooperation with the pin 36 that is carried by the slidable actuating bar 6 for moving the hook into locking engagement withl the keeper 34 when the bar 8 is moved unwardly.
A bent finger 31 extends from the lower portion of the pivoted hook and is adapted to engage with the lower portion of the bracket 32 to limit the swinging movement of the pivoted hook in one direction. It is. of course, understood that this hook-like fastener is gravity actuated, so that the same will be released from the keeper 34 when the pin 35 is moved downwardly away from engagement with thelip 35, upon the actuating' bar being moved downwardly.
For the purpose of locking the lower sash 4 inits fully closed position, I provide the lower end of theslidableactuating bar 5 with an oilset hook 38, (see Figure 16 of the drawings). This hook cooperates with the lug mounted on the bracket that is secured on the lower sash 4.
Also forming an important feature of my improved awning type window is the means for holding the slidable actuating par in any vertically adjusted position and thus hold the swinging sashes in any angularly adjusted position. This means comprises in providing transverse serrations 4I in the outer face of the lower end portion of the actuating bar 5 and forming similar serrations on the inner face ofthe lower platelike member 1.-
A short shaft 42 is mounted-for oscillatory movement in the window frame I, an actuating handle 43 being secured to the outer end of this shaft. A cam forming pin or projection 44 is carried by the inner end of the shaft 42 and is operable in a suitable cavity 45 provided therefor in the window frame.
The outer free end of this pin 44 is disposed adjacent the inner face of the serrated portion of the actuating bar 5 and is adapted to force the teeth 4| on said bar into locking engagement with the serrations on the inner face of the lowermost plate-like member 1 when the shaft is turned in one direction, thereby locking and holding the bar against sliding movement and holding thel sashes in any adjusted open position.
The operation of thisv awning type window may adjusted position by actuating the shaft 42 and be stated as follows. With the parts disposed in the position shown in Figure 2, all of the vertically swinging sashes are locked in their fully lclosed position and the actuating bar is in its uppermost position in its guides. When it is desired to open the window the handle 38 is iirst swung out of locking engagement with the keeper 8|. Then the central sash 3 is pushed outwardly.
This will automatically cause the hinge units associated with the upper and intermediate sashes to move the actuating bar 6 downward. During the downward movement of the bar 6 the locking means for the top and lower sashes will be released.
By referring to Figure 3 of the drawings it will be observedthat the top and intermediate sashes have been partially swung to an open position,V
while the lower sash 4 still remains in its closed position. In/this manner, the ventilation through the window can be controlled or regulated, preventing drafts, etc.
Further outward pushing on the handle will cause the upper and intermediate sashes to swing to a still further open position andfat the same time cause further downward movement of the bar 5, resulting in the keyhole slot 22 in the bracket 20 cooperating with the pin 25 so that when this pin'reaches the enlarged portion of the keyhole slot, the flanged nger 28 will coact with the arcuate shoulder 23 to cause the lower sash 4 to swing outward to an open position. This movement iswhat I term as the openingA of the lower sash.
By reason of the const of parts as shown and described, it will be obdelayed ction and arrangement bar 50.
served that the upper and intermediate sashes will operate simultaneously.
When all of the sashes have been swung to their fully open position, the .parts assume the position illustrated in Figure 4. As heretofore stated, the sashes may be held in any angularly the locking means controlled thereby.
When the sashes are returned to a closed position, the lower sash will assume its fully closed position ahead of the other two sashes. Thus the lower sash opens last and closes iirst.
The locking means for the upper sash will be brought into operation as the upper sash approaches a fully closed position, while the locking means for the delayed opening sash is brought into operation upon the further upward movementof the sliding bar, after the delayed opening sash is in its fully closed position.
Upon the sashes being moved to their fully closed position, the upward movement of the bar 5 will automatically operate the locking means for the upper and lower sashesin the manner heretofore explained. When the several sashes are locked-in their fully closed position there will be rattling or loose fit of the sashes. By adjusting the hinge units, the degree of opening of the sashes may be regulated in a positive and efficient manner, and also faster closing of the delayed sash can be eiected, and tight closing of all ofthe sashes will be attained, so that the automatic locking means will :properly function. l
Attention is now directed to Figures 1'1 to 23, inclusive, wherein I have shown my invention as associated with a metal window frame and wherein metal sashes are employed. However,
the principles of voperation are the same.
In this form, the channeled metal window frame is designated by the numeral 46 and the metal frame of the sashes designated at 41, 48 and 49, respectively.
Mounted for vertical slidable movement, in the. channeled metal frame 46 is the actuating This bar is formed with longitudinal slots 5| through which extend theA pivot forming Iscrews 52 that are threaded into the base portion of the channel shaped frame 48.
`The hinge unit for theupper metal sash 41 comprises a leg member 53 that is fixedly attached to the side edge ofthe sash 41. An offset arm 54 is formed at the upper end of the leg member 53 and this arm is pivotally connected to the upper end portion of the sliding bar -50 as at 55.
A link 55 is pivotally connected at its upper end to the lower portion of the leg member 53 as at 51, while the lower end of this link is pivotally connected to the uppermost screw 52.
The hinge unit lthat is associated with the 58 that is iixedly secured to the side edge of said intermediate sash. A link 5% is pivotally connected at its upper end to the lower portion of the leg member 58 as indicated at 50. The lower end of this link has pivoted connection with the intermediate pivot forming screw 52.
The upperl end of the leg member 58 is formed with an offset arm portion 5| and this arm portion is pivotally secured to the upper portion of the adjustably mounted bracket 62 as at r 55|.' This bracket 52 is adjustable vertically on the bar 50 and is secured thereon by the'means indicated generally at 54.
Theupper end of the bracket 62 is formed with a curved edge 65 with which coacts the arcuate flange 66 formed on one side edge portion of the arm 6I.
The hinge unit provided for the lower sash 49 which embodies the delayed opening principle, includes a leg member 61 that is xedly attached to the side edge of the lower sash. A link 68 is pivotally connected at its upper end to the lower portion of the leg member 61 as at 69. The lower end of this link has pivotal connection with the the bracket 12 and is adapted to cooperate with the stop kforming ilange 16 formed on one side edge of the leg member 61. The lower end of this flange 16 is formed with a projecting ear 11.
An automatic locking means designated generally by the numeral 18 is provided for the locking of the upper sash in its fully closed position. This lock is identical with the lock conbar in the meantime will have actuated the automatic locking means provided for the upper and lower sashes.
Means may be provided for holding the metal sashes in any angularly adjusted position similar to that employed in conjunction with the wooden sashes.
It will thus be seen from the foregoing description that I have provided an awning type window that can be readily and easily assembled, installed and operated and due to its simplicity will be inexpensive, yet strong and durable and at all times positive and eilicient in its operation.
While I have shown the preferred embodiment of my invention, it is to be understood that various changes 'in the size, shape and arrangement of parts without departing from the spirit of the invention and the scope of the appended claims, may be made.
What I claim is:
1. A window construction comprising in combination, a frame, a plurality of vertically swinglng sashes mounted in the frame, an actuating bar mounted for vertical sliding movement in the frame, means for pivotally connecting all of the sashes to the sliding bar, one of said sashes constituting the means for actuating the sliding bar,
struction employed for securing the upper sash iinger 19 that projects from the lower sash 49.
The operation of the metal awning type window may be briey stated as follows. With the parts arranged in the position shown in Figures 17 and 18, all of the vertically swinging sashes are locked in their fully closed position and the actuating bar is in its uppermost position.
By pushing outwardly on the operator associated with the intermediate sash 48, the hinge units associated with the upper and intermediate sashes will cause the bar to move downwardly. During the downward movement of the bar 50, the locking means for the top and lower sashes will be released.
The upper and immediate sashes will swing outwardly to a partially open position while the lower sash still remains in its closed position.
Further downward movement of the actuating bar 50 will cause the slotted bracket 12 to move downwardly on the pin 14 until the lug 15 is disposed below the lower edge of the flange 16 and is clear of the ear 11.
When the parts have reached this position, the curved ange 1I will be clear of the adjacent side edge of the bracket 12 and will be ready to ride over the curved upper end 80 of this bracket,
whereby the sashes may be opened or closed depending upon the direction of movement of the sliding bar, certain of said sashes being actuated simultaneously, means interconnecting the sliding bar and another of the sashes for causing a delayed opening of said last mentioned sash, and interengaging means carried by the sliding bar and the delayed opening sash for automatically locking the latter sash when the same is in a fully closed position, upon further continued movewhereupon, further outward movement of the operator sash will cause the lower sash 49 to also swing outwardly to an open position. Thus a delayed opening of the lower sash is eiected by this particular hinge construction.
When the sashes are returned to their closed position, the lower sash will assume its fully closed position ahead of the other sashes.
When the sashes are all intheir fully closed position, the upward movement of the actuating ment of the sliding bar.
2. A window construction comprising in combination, a frame, a plurality of vertically swinging sashes mounted in the frame, an actuating bar mounted for vertical sliding movement in the frame, means for pivotally connecting all of the sashes to the sliding bar, one of said sashes constituting the means for actuating the sliding bar,
whereby the sashes may be opened or closed de` pending upon the direction of movement of the sliding bar, certain of said sashes being actuated simultaneously, means interconnecting the sliding bar and another of the sashes for causing a delayed opening of said last mentioned sash, interengaging means carried by the sliding bar and the delayed opening sash for automatically locking the latter sash when the same is in a fully closed position, upon further continued movement of the sliding bar, and additional interengaging means carried by the sliding bar and one of the iirst mentioned sashes for automatically locking said sash as the same approaches a, fully closed position. 3. A window construction comprising in combination, a frame, a plurality of vertically swinging sashes mounted in the frame, an actuating bar mounted for vertical sliding movement in the frame, means for pivotally connecting all of the sashes to the sliding bar, one of said sashes constituting the means for actuating the sliding bar, whereby the sashes may be opened or closed depending upon the direction of movement of the sliding bar, certain of said sashes being actuated simultaneously, means interconnecting the sliding bar and another of the sashes for causing a delayed opening of said last mentioned sash, and interengaging means carried by the sliding bar and one of the rst mentioned sashes for automatically locking the latter as the same aple 0f this patent: 2,272,722
