My improved sash fastener can be used with any type of swinging sash though the same is particularly applicable to a storm sash hinged at its upper end for swinging movement into and out of the frame with which it cooperates. The invention will hence be described as used in conjunction with such type of construction.

For the purpose of illustrating the application of my invention, I have shown in Fig. l a window indicated in its entirety by the reference numeral ID. This window comprises a frame 59 ll arranged with stops l2, l3 and I4 which slidably support lower and upper inner window sash l5 and I6. In conjunction with frame H a storm window I1 is illustrated which is constructed with stiles 18 connected together through nails 2|, 22 and 23 and supporting the window panes 24 in the usual manner. The frame I!) further includes a header 25 to which the storm window I! is hingedly connected by means of a sash hanger 26 in the usual manner so as to permit of swinging of the sash outwardly as shown in Fig. 1 or to permit the same to be swung into the rabbet formed adjacent the stop l4 and indicated at 2'! as shown in Fig. 2. For the purpose of readily manipulating the various sash suitable pulls, not shown, may be employed whereby the sash may be opened or closed in the usual manner.

My invention preferably embodies two sash fasteners which are attached to the stiles |8 of the sash l1 and to the frame Both of these devices are identical in construction except that one is left handed and the other right handed and for this reason only one of the fasteners has been illustrated which is indicated in its entirety by the reference numeral 28.

The sash fastener 28 as best shown in Fig. 1 comprises an arm 3| which is pivoted to a mounting 32 attached to the storm sash I1 and which cooperates with a bracket 33 attached to the frame These parts will now be described in detail.

The mounting 32 is constructed of sheet metal and is bent to provide a base 36 which is adapted to be secured to the rail i8 of the storm window H by means of screws 34. Extending outwardly from the base in an ear to which the arm 3| is pivoted.

The arm 3| is also constructed of sheet metal and is formed from a narrow strip of metal provided at one end with a circular head 36. This head is drilled to receive a rivet 31 which passes through the ear 35 and said head and which is riveted in place to provide a pivot or pintle for hingedly connecting the arm 3| to the mounting 32. Near the other end of the arm 3| the same is constructed with a quarter twist 38 by means of which a portion 39 at the end of said arm is provided which extends in a plane at right angles to the plane of the arm proper. Ear 35 as shown in Fig. 1 is so arranged that the body of the arm proper is vertical whereby the portion 39 is substantially horizontal when the window is open. The portion 39 forms the latching member of the invention which will be subsequently more fully described.

The bracket 33 like the mounting 32 is constructed from sheet metal and is bent to form a base 4| which is attached to the stop M of the window frame H by means of screws 42. Issuing outwardly from the base 4| is a flange 43 which is constructed with an opening 44 in the shape of a cross. This opening has two vertical reaches 45 and 46 and two horizontal reaches 4? and 48 all of which function in a manner to be presently described in detail. The flange 43 at the two reaches 45 and 46 of the opening 44 is constructed with converging edges 5|, 52, 53 and 54. In addition, the flange 43 is constructed with upper and lower edges 49 and 50 at the reaches 45 and 46 which are connected to the edges 5|, 52, 53 and 54.

The latching member 39 as shown in Figs. 8 and 9 is constructed with two notches and 56 which face outwardly and which are so proportioned that seats 51 are formed in the ends of said notches which are adapted to engage the edges 53 and 54 of the flange 43 formed at the reach 46 of the opening 44. The notches 55 and 56 are constructed wedge shaped and of suitable dimensions so that the minimum width thereof is slightly less than the thickness of the metal of the flange 43. Likewise the distance between the seats 51 is slightly less than the minimum distance between the edges 53 and 54 and 5| and 52. In this manner the latching member 39 may be wedged in between the edges 53 and 54 of the flange 43 when downward pressure is applied upon the same. It will be noted in Figs. 1 and 5 that the latching member '39 is bent slightly upwardly from the arm 3|. This is for the purpose of making the same substantially horizontal when the sash is open to procure proper engagement of the notches 55 and 56 with the edges 53 and 54. By means of this construction the arm may be rigidly attached to the bracket 33, in such a manner as to prevent movement of the said arm with reference thereto, thereby eliminating rattling of the parts of the arm and rattling of the storm sash.

At the end of the latching member 39 is provided a finger piece 58 which is formed by bending the extreme end of the metal from which the arm 3| is constructed downwardly in the shape of a hook. The bend between the finger piece 38 and the latching member 39 is constructed with a luxurious curve 59. This is for the purpose of providing a rounded surface which engages the sash IS in the event that the fastener should become disengaged from the holding means therefor when the storm sash I! is in closed position. By means of this rounded corner the fastener can slide freely along the sash so that it becomes impossible to cause the sash |5 to jamb in the event that the fastener becomes disengaged.

The finger piece 38 is of a width slightly less than the narrowest portion of the reach 46 of opening 44 and is of a length less than the distance between the ends 49 and 56 of the reaches 45 and 46 of said opening. This permits of sliding the said finger piece through the opening 44 for the purpose of detaching the arm 3| from the bracket 33. The latching member 39 is of a width greater than the maximum width of the reach 46 so that the notches 55 and 56 may become engaged with the edges 53 and 54 of the bracket when disposed at such reach. However, this portion of the arm is of a width less than the distance between the ends of the reaches 41 and 48 as shown in Fig. 7, so that the said portion of the arm may slide freely in this part of the opening 44. Adjacent the two notches 55 and 56 on latching member 39 are two lugs 6| and 62 which are of a width slightly greater than the width of the latching member 39. These lugs prevent the arm from sliding past the notches 55 and 56 when moving outwardly, whereby positive engagement of the notches 55 and 56 with the edges 53 and 54 is procured. Adjacent the lugs 6| and 62 the portion 63 of latching member 39 is reduced to the width of the finger piece 58. This is for the purpose of permitting the disengagement of the hook 58 from the bracket 33. When the arm 3| is raised as shown in Fig. 7, the lugs 6| and 62 may be slid outwardly through the opening 44 and the portion 63 is disposed within said opening. When the parts are so arranged the lowermost end 64 of finger pece 58 engages the lowermost end of the bracket and prevents disengagement. By raising the finger piece 58 until this portion extends above the lowermost edge of the reach 46 the portion 63 will be disposed in reach 45 and the entire length of the finger piece being less than the distance between the ends 49 and 50 of the reaches 45 and 46 the finger piece .may bepassed through the opening 44 and the arm disengaged from bracket 33..

The lowermost edge 65 of the arm 31 slides along the edge 50 of the flange 43 of bracket 33 when the arm 31 is traveling through the opening 44. In such position the latching member 39 would come opposite the edges 53 :and 54 when the twist '38 was reached. For the purpose of raising the latching member 39 to 'a position where the same enters the reaches 4'! and 48 of the opening tithe corners of the flange 43 at the intersections between the various reaches of the opening 44 are rounded as indicated at 136. Que-0f these cornersengages-the twist .38 andelevates the arm so that the latching member'39 is guided into the recesses and 48 of the opening 44. In opening the sash it is, therefore, only necessary to force the sash open by applying pressure directly to the same and the notches 55 and 56 will eventually become engaged with the edges -53-and 54 without manual effort.

In order to hold the sash partly open the edge 65 of the arm 3-! is constructed with notches 61, 6t and til which are adapted to engage the edge 5% of the flange 63. ,Notchfifi is fairly close to the vrivet 3'! and when this notch engages the flange -43 the window is almost closed as shown in Fig. 3. If by lowering the lower sash it until the same engages the top of arm 13! a burglar proof fastener results preventing forcible entry from the exterior to the interior. Notch 63 is so positioned that the opening between the storm sash H and the frame H is so small that the hand cannot be inserted into the same. While the sash i5 rests uponarm 3! the same cannot be moved and it, therefore, becomes impossible to open the window from the exterior.

For the purpose of opening the sash and particularly where the sash is frozen to the frame, arm 3i is used as a lever. At the end of this arm as shown in Fig. 5 is -a projection H which serves as a pry. This projection has a hooked edge 12 which has two parts 1.2a and lZb-adapted to engage the edge '53 of flange 43 of bracket 33 when the arm 3| is raised as shown in Fig. 4. Initial movement of the arm 3| upwardly brings the part Ha. of edge l2 into engagement with the edge 53 of flange -63 which causes the sash t? to be elevated and to be moved toward its hinges. This has the effect of breaking the ice and freeing the sash. As the arm 3| is further raised the portion Nb of edge 12 is brought into engagement with the edge 53 of flange 43 which operates to forcibly move the sash outwardly. After outward movement of the sash is started the sash can be readily moved to any of its several positions by merely sliding the arms 3| in the brackets 33.

In order to lock the sash in closed position, the bracket 33 is so situated that when the arm 3! is in its downward position, :as shown in Fig. 2, the edge -55 of said bracket engages the surface M of the flange d3 of bracket 33 and forces the sash inwardly. To hold the arm 31 in place a nail 15- is employed which is driven in the stop Hi as best shown in Fig. 9. This nail fits in back of the latching member 33, as illustrated and holds the same in proper position. To prevent lateral movement of the arm 31 so as to prevent disengagement from the nail, an opening or cavity is formed in the latching member 33 which receives the head it. This opening provides shoulders which directly engage the nail head and prevent unintentional disengagement with the arm 3i .Itwill benoted that the rivet 31 partly passes through the opening 44 :in bracket 43 when the sash is closed. To accommodate the head thereof, it is necessary that the head be disposed in reach 48. To cause this 'to occur .a fillet is formed in the bracket 43 between the edges 58 and .54 which when engaged by the edge 65 of arm 3 moves the rivet upwardly into reach 48. It, therefore, becomes impossible to erroneously install "the parts of the invention.

The use-of the invention is obvious. Assuming the sash to be in closed position as shown in Fig. 2 to open the sash it merely becomes necessary to move the arms 3| toward the sash to dis engage the head "E6 of the nail 15 from the shoulders formed byopening Tl. Arms 3! can then be moved laterally to become disengaged from the nails and can be swung upwardly. When the arms reach a position such as shown in Fig. l, the .pry H engages the edge -56 of the flange 43 of bracketSt, with the result that the window if! is both raised and forced outwardly. Thereafter-the arms may be slid through the opening it in the flange =43 of brackets 33 and if the window is desired to be maintained partly open the notches .61, 68 or 69 maybe brought into engagement with the :lower edges .56 of the brackch; 33. If the sash is desired to be :in fully open position, the notches 55 and '55 are brought into engagement with the edges 53 and 54, whereby a wedging action is procured which holds the arms 31-rigidlyattached tothe brackets 33. With the parts so arranged, rattling of the sash and fasteners isentirely prevented. When it becomes necessary to disengage the arms 3! from the brackets 33, these arms are raised until the latching members .33 come opposite the reaches 4i ing the twist in the arms the latching members in are arranged in substantially horizontal position when the sash is open, thereby affording suitable surfaces to which pressure may be applied in wedging the parts together. My invention is entirely rattle and noise proof when arranged to hold the sash fully open. By means of the lugs adjacent the notches in the arms, the arms will not become unintentionally disengaged from the brackets with which they cooperate. By constructing the notches in the latching member wedge shaped the same are readily brought into engagement with the edges of the bracket with which they cooperate. By the arrangement of the fillet at the bottom of the opening in the bracket, erroneous installation of the invention is prevented. The finger pieces being constructed in the manner illustrated are easy to manipulate and are readily disengaged from the brackets when occasion demands. Due to the curvature between the finger pieces and the arms, iambing of the sash is prevented in case the arms become unintentionally dis-en gaged from the nails holding the same in closed position. The shoulders formed 'for engagement with the heads of the nails prevent unintentional disengagement of the arms from the nails.
