Patented Sept. 6, 1938 UNlTED STATES PATENT OFFICE DEVICE FOR HOLDING HINGED CLOSURES IN OPEN POSITIONS 6 Claims.

This invention relates to new and useful improvements in devices for holding hinged closures in open position. I

In hinged closures which are hinged at the top and swing on horizontally disposed pivots,

such as basement windows, it is necessary to provide means for holding the window open. Generally a hook and eye is used for this purpose. This is unsatisfactory for several reasons as it is necessary to use both hands in opening and closing the window; the hook which is generally attached to the floor joist or ceiling of the basement is unsightly and usually hard to reach; and, furthermore, it is not possible to regulate the extent of the opening of the window.

The object of the present invention is to provide a device which is attached to the window frame and to the window sash and is automatically operated to hold the window in open position and which is neat in appearance.

Another object of the invention is to provide a device of the class described which can be operated to open the closure member to the full extent or to open it only partially in any number of various positions and which is automatically operated by the movement of said closure member.

Additional objects of the invention are to provide a device for basement windows and the like which can be easily attached in position, is of simple but durable construction, and. can be economically manufactured.

With these and other objects in view, my invention consists in certain novel features of construction and arrangement of parts, hereinafter more fully described and claimed, and illustrated in the accopmanying drawings, in which-- Figure 1 is a front elevational view of my device showing it attached in position.

Figure 2 is an enlarged cross section taken on line 2-2 of Figure 1.

Figure 4 is a fragmental longitudinal cross section showing the device in position when the window is being closed.

Figure 5 is a perspective detail view of the pawl member.

Figure 6 is aside elevation partly in cross section of a modified form of my invention.

Figure 7 is a longitudinal cross section of my device.

Figure 8 is a cross section taken on line 88 of Figure 6.

Figure 9 is a cross section taken on line 9-9 of Figure 6 and showing the pawl in a moved position.

Referring by numerals to the accompanying drawings, N) indicates one of the stiles of a window frame and l l a sash window which is hinged at the top to said frame as shown at I2. I4 is a device provided for holding the sash open in any position.

This device includes an elongated housing l5 fixed to the stile l0 longitudinally thereof and near one of the upper corners of sash II, a bracket l6 fixed to the window sash ll adjacent to the upper end of said housing, and a link I! pivotally connected at its upper end to said bracket, as indicated at l8 and having its lower or free end l9 operatively extending into said housing.

The bracket l6 has its shank portion bent or offset as indicated at lfia in order to bring the outer end thereof adjacent to the upper end of link H. In this manner link I1 is not distorted and the device can be used at either side of the sash simply by transposing the bracket Hi.

The housing l5 comprises a base plate and a cover 2!. The ends of the plate 20 extend beyond the ends of cover 2! and are apertured to receive screws 22 by means of which said housing is secured to the window frame. The cover 2! is detachable from said plate and is secured thereto in any suitable manner. A longitudinally disposed bar 24 is secured to base 20 to one side of the longitudinal axis of said housing. This bar is formed with a horizontally and longitudinally disposed ledge 25 which is spaced a suitable distance from base 20 to provide a clearance or space 25a. The ends of this ledge terminate short of the ends of cover 2| so as to provide spaces or

clearances

26 and 21, respectively. The upper face of this ledge is formed with a plurality of ratchet teeth 28 presented rearwardly or toward the pivot I 8.

The outer or lower end l9 of link l! is disposed angularly to said link and enters said housing l5 through a slot 29 formed longitudinally in cover 2|. A block or pawl 3c is pivotally mounted on the extremity of said end l9, as indicated at 3|. A tooth 32 extends laterally from said pawl and is adapted to engage the ratchet teeth 28 of bar 24. A spring 34 engages block 38 and presses it downwardly or toward the base 24.

Block 39 occupies a position in housing l5 to one side of the bar 2t and the ratchet teeth portion 25 while the tooth 32 is disposed in the vertical planeof said portion 25. When the window is closed the parts occupy positions shown in Figures 1 and 2. In this position block 30 is disposed in the forward end of housing 15 with the tooth 32 disposed forwardly of the forward end of the ratchet bar 25. The underside of tooth 32 is curved, as indicated at 3260, and when the window is moved into open position bracket l6 raises the upper end of said link so that the curved underside 32a of tooth 32 moves upwardly over the toothed face of the bar 25. As the tooth 32 passes each tooth 28, the end 32?) of said tooth 32 is adapted to engage the straight face of the tooth 28, thereby holding said block 38 against retrograde movement and holding said window in open position, as shown in dot anddash lines in Figure 2. Thus each tooth 28 represents a predetermined open position of the window.

When it is desired to close the Window it is moved to its extreme upper or open position, whereupon the block 35 will move past the upper or rear end of ledge 25 and will drop against the base plate 20. This will position the tooth 32 below the ledge 25 and as the window is moved into closed position block 39 will travel forwardly with the tooth 32 traversing the space 2511, as shown in dot-and-dash lines in Figure 4. Upon reaching the extreme forward position, i. e., when the window is closed, the parts will assume position shown in full lines in Figure 2.

In the modified form shown in Figures 6 to 9, a ratchet tooth member 35 is formed integrally with the base 36. One side of the latter is formed with an extension which terminates short of the ends of said base and is bent upwardly as indicated at 35a and then horizontally as at 3617 and then again upwardly to present the teeth 35 upwardly. The horizontal portion 36b is spaced suitably from the base 35 to provide a longitudinally disposed runway 31 open on one side and at both ends. An elongated pawl 38 is pivotally mounted at one end to a bracket 39 by a pivot 39a. This bracket is fixed to a closure member 40 while the base 35 is fixed to a stationary member 4|.

The outer or free end of arm 38 is formed with a laterally projecting tooth 38a which traverses the vertical plane of teeth 35.

A leaf spring 42 is fixed at one end to the underside of base 36 as indicated at M, and extends through an opening in said base into said runway 31 and forwardly and diagonally thereof with the free and 42a projecting a suitable distance past the forward end of the tooth member 35 and runway 3?.

A housing 45 is attached to the base 35 and encloses said tooth member 35 and runway 37 and the free end of arm 38. The top and one end of said housing is slotted as indicated at 46 to allow said arm to operate therethrough.

When the closure member 30 is closed the parts occupy positions shown in full lines in Figure 6, with the pawl or tooth 38a resting upon the free projecting end 42a. When the closure member is moved to open position the arm 38 is moved forwardly and the tooth 38a rides over the teeth of member 35. The reverse movement of the arm 38 is prevented by the engagement of the tooth 38a with the square side of said tooth. Thus the closure member can be supported in any number of positions by the engagement of tooth 38a with the corresponding tooth of ratchet member 35.

To close member ii! the latter is opened to cause the tooth 38a to move past the rear or upper end of member 35, whereupon the free end of into the position shown in Figure 6.

A coiled spring 47 is arranged on the pivot 39a and connected to arm 38 and tends to hold the tooth 38a against the teeth of member 35 and against the base 36 when cleared of member 35. The tension of this spring 4'! is less than that of leaf spring 42 so that the latter is capable of raising the free end of said arm 38 as described.

My device is of simple construction, can be easily applied, and is reliable in operation.

While I have disclosed herein my invention as being applied to a window, it can be equally as well used in connection with bread boxes, trunks, chests and with other hinged closure members. It is obvious that various changes can be made in the construction and arrangement of parts of my device without departing from the spirit of my invention.
