For the purpose of illustrating the application of my invention I have shown a portion of a window which is designated by the reference numeral M). This window comprises a window frame i! having a stop l2 extending about the same and forming a rabbet H3 in which the storm sash M is received. This frame also provides a groove l5 in which the regular sliding sash of the window is disposed and which forms no particular feature of the invention and has not been shown in the drawings. Only a portion of the sash it is illustrated namely one of the stiles it thereof which carries a pane of glass ll supported therein in the customary manner. The invention may also be used for screen sash and it is to be understood that where the word storm sash is used, a screen sash is also intended.

In the use of the invention, preferably two sash stays and fasteners are employed, one on each side of the storm sash. These sash stays and fas-- teners are, however, identical in construction except that one is left handed and the other right handed and only that used on the left hand side of the window has been illustrated and will be described. This sash stay and fastener comprises 40 a pair of jointed arms l8 and it which are pivotally connected together at their joining ends by means of a friction joint 211. The arm it is pivoted to a mounting 22 secured to the stile iii of sash it, while the arm I8 is pivoted to a mounting 23 secured to the stop l2 of the window frame it. These parts will now be described in detail.

The arm i8 is constructed from sheet metal and is stamped to provide a shank having circular ears 25 and 26 at the ends thereof. The 50 ear 25 is pivoted to the mounting it which consists of a flat plate 2i of a width equal to the width of the stop M. This plate is secured to the stop it by means of screws 28. Between the ear 25 and the plate 23 is a friction washer 29 which is 55 showing the constructed of fibre or some other similar material. A rivet 3| passing through the ear washer 29 and plate 21 and riveted over said plate serves as the pintle for connecting the arm E8 to the mounting 23.

The arm I!) is constructed similar to the arm l3 and is formed with a shank 32 and circular ears 33 and 34 at the ends thereof. Issuing outwardly from the end of the ear 26 of arm I8 is a strap 35 which terminates in another circular ear 36. The strap 35 is bent U-shaped in form, as shown in Fig. 2, so that the ear 36 overlies the ear 26. The car 34 of arm I9 is disposed between the ears 26 and 36. Between the three ears are arranged friction washers 31 and 38. A bolt 39 having a square head 4| passes jointly through the ears 26, 34 and 36 and the washers 31 and 38. The head 4| of bolt 33 is received within a square hole in the head 26 and is held from rotation thereby. Upon the end of the bolt 39 is a nut 42 by means of which the joint may be tightened. Nut 42 engaging the ear 36 which is integral with the ear 26 is thereby prevented from rotating as the arms l8 and I9 swing relative to one another. The strap 35 is so arranged that the portion thereof, designated by the reference numeral 43, engages the edge 44 of arm |9 and limits the opening movement of said arms so that the arms cannot be arranged with dead centers. This permits of closing the sash by merely drawing on the pull thereof and without prior adjustment of the arms.

The mounting 22 is constructed in the form of a bracket from sheet metal which is stamped and bent to provide a base 45 and a flange 46 extending outwardly therefrom. Base 45 is adapted to be secured to the stile l6 of storm sash M by means of screws 41. The flange 46 of bracket 22, as best shown in Fig. '7, is formed with an opening 48 which extends upwardly from the base 45. The uppermost portion of this opening is reduced and formed in the shape of an arcuate groove as indicated at 49, which groove provides a bearing 5|.- The ear 33 of arm l9 has issuing outwardly from it a pintle 52. This pintle is constructed with a spindle 53 and a head 54 at the end of the same. The other end of the spindle is constructed with a stem 55 which extends through the ear 33 and is riveted thereto. Head 52 is larger in diameter than the spindle 53 to provide a shoulder 60. The extreme end of this head is tapered as indicated at 56. The opening 48, in flange 46, is of suitable dimensions to permit of inserting the head 54 of pintle 52 through the opening. The tapered end 56 of the head 54 facilitates such insertion. The spindle 53 is of a diameter suitable to be received within the opening 49 and is guided for rotation in the bearing 5|. When the parts are applied, as shown in Fig. 6, the shoulder 60 prevents axial movement of the pintle 52 in one direction and thereby prevents disengagement of the spindle 53 from the bearing 5|.

For holding the spindle 53 in engagement with bearing 5|, a keeper is employed which is indicated in its entirety by the reference numeral 51. This keeper is constructed from sheet metal which is stamped to provide a body 58 pivoted to the base 45 of bracket 22 by means of a rivet 59. The body 58 has formed on it a head 6| which is offset from the plane of the base 45 and which is provided at its center with a groove 62. Groove 62 is adapted to receive the head 54 and forms a further bearing for the pintle 52. This bearing, in conjunction with the bearing 5|, guides the pintle for rotation relative to the supporting bracket 22.

In order to force the pintle 52 into the groove 62, head 6| is constructed with a cam 63. This cam is turned down to form a sloping cam surface 64, best shown in Fig. 3, which engages beneath the pintle 52 and forces the said pintle upwardly into the reduced portion 49 of opening 48 as the keeper is rotated. The outer surface 65 of the cam 63 is arcuate to cause the same to clear the flange 46 of bracket 42, said cam moving in close proximity thereto. The head 6| is also constructed with a stop 66 which is adapted to engage the flange 46 of bracket 22 when the pintle 52 is in engagement with groove 32 to limit further swinging movement of the keeper 51. The bracket 22 is preferably arranged so that the stop 66 is uppermost whereby the keeper is held through the action of gravity in proper position. The body 58 of keeper 51 is provided with two upstanding lugs 61 and 68. These lugs are spaced apart a distance slightly greater than the width of the average screw driver and are used for rotating the keeper 51. When the screw driver is placed between these lugs and turned rotational movement is imparted to keeper 51. The lug 61 is preferably constructed a little longer than the lug 65 so that the same may be grasped by a pair of pliers and the device rotated thereby instead of by a screw driver.

My improved sash stay and fastener is adapted to be locked in closed position by the swinging of the two arms i8 and i9 jointly after the sash is in closed position. For this purpose the two arms 58 and i9 are of the same length from pivot to pivot and the pivots formed by pintle 52 and rivet 3| are disposed so that the same overlie one another when the storm sash is closed. In addition, a lug 1| is employed which extends outwardly from the arm l8 and which is adapted to engage the edge 12 of arm l9 when the two arms are brought together. into final position, this lug resists opening of the sash and holds the same in locked position.

The method of installing and using the invention is as follows. The storm sash I0 is first closed, as shown in Figs. 2 and 3, and the two arms i8 and is of the sash folded up and placed along the stop l2 and rail Hi. The fasteners may be arranged at any desired locality with reference to the hinge of the sash, it being borne in mind that the lower the disposition of the fastener the less the movement of the sash. While properly disposed the bracket 22 is secured to sash I4 through screws 41. The uppermost of the screws 28 is next applied .and thereafter the.

sash is openedand the lowermost of said screws is next applied. If two sash fasteners are employed, the other is similarly installed, care being taken to install the fasteners with the pivots of the brackets thereof .at the same distance from the axes of the hinges of the storm sash. The arms l8 and IQ of the fastener are prevented from fully opening by means of the corner 43 of strap 45 which engages edge 44 of arm l9. By merely manipulating the sash through the pull attached to the lower rail thereof the sash may be opened and closed and the two arms I8 and I9 follow the movement of the sash and swing from open to closed position and vice versa. When the sash has been completely closed the arrangement of the parts is .as shown in Figs. 2 and 3. If it becomes desirable to lock the sash, the two arms l8 and I9 are swung jointly from the position shown in Figs. 2 and 3 to that shown When the arms are swung in Fig. 4. In the latter position the lug 1| pre-" vents opening of the arms and the sash remains locked in closed position.

When, at the end of the season, the storm sash is to be removed, the keeper is swung by means of a pair of pliers or screw driver to disengage the pintle 52 from bearing 5i. Thereafter the pintle may be slid outwardly from the opening 48. This is accomplished by pressing the two arms l8 and I9 together. To facilitate such movement, the arm I8 is constructed with an offset 73. Arms l8 and [9 may, if desired be constructed with ribs H which stiffen the same. In Fig. 2 the keeper 5'! has been shown as swung away from the pintle 52, said pintle being in a position to be disengaged from the bracket 22. A bracket similar to bracket 22 may be applied to the screen sash if a screen sash is to be used in place of the storm sash. The pintle 52 may be thereafter applied to the bracket of the screen sash and the screen sash may then be operated in identically the same manner as the storm sash.

The advantages of my invention are manifest. An extremely simple .and practical device is provided whereby storm sash or screen sash may be held in adjusted position in a manner such as to prevent rattling. The device for holding the parts detachably connected is easi1y operated and will not become unintentionally disengaged. The sash stay and fastener can be constructed at a nominal cost. By means of the locking lug utilized the sash can be locked in closing position.

Changes in the specific form of my invention, as herein disclosed, may be made within the scope of what is claimed without departing from the spirit of my invention.
