mer'al 10, is provided with any suitable screen material 11 secured to said'franie 10' as by the moulding strips 12. Theup'per and outer edge 13 of the top member 14 of the frame 10 is beveled as indicated to corres-pon'd with and abut the inclinedsur face 15 of'tlie" casing 2. In a similar way the bottom strip 16' of the frame" 10 is pro vid'edwith the I in'c'lined surface 17- to correspend with and" substantially it against the inclined;- surface 18' of the window sill 6 when said frame 10 is in closed position The entire relative tothe window casing. frame lO'is adapted to swing on the hooks 20"s"e'cu'redto the upper casing 2, s'aid'hooks' being engaged by the slotted members 21 secured to the upper member 1 1 of theframe 10, in the usual= and well known Secured to one of the side mem bersysuch as 25,-of thefr'ame 10 is the angle member 26 provided with the pin 27' pivotallv-supportingaispacingjbar 30.

hespacing'bar 30; seeFigures 1 7 8' and 11, has cam notch 31 in one edge thereof near the pivot 27, a plurality of holes" 32 disposed in spaced I relation to each other, and u-liolding notch 33' located in the same edge withthe cam=notch 31 but disposed be- ,yond theholes-32 and near the free'end of the bar 30.'- The extreme free end of the bar' 30 isbent substantially at right angles to the mainbody portion' thereof' to-form a foot 35 t-he' side edges of which are inclined relatively to said body portion as clearly shown in Figures 45, 5,=6'and 10. This foot 35-is provided with a suitable opening 36 to receive the-bolt of the latch tO'secured to said frame lOnearthe bottor'n member 1 5 there of. Also one edge of the foot 35 isbeveled as at 3 7 to aid'the' bolt of'sa id-latch 10 in engaging the aperture'36'of-the spacing bar,

The latch 4e0maybe of any suitable type such as that indicated in the drawings where in the boltel" thereof is controlled asby the spring 42 and operated'by the thumbkneb 43 secured to the said bolt and working thr'o'ug'ha slot 14 in'the casing'o'f the liI-teh- 10. Said latch is so disposedjon the frame 10- of the screen that the spacing bar' 30 when swung from its pin27 downwardly willcause be engaged by'the' bolt 41 of said latchas- Ill (ill

window is the bracket 50, see Figures 1, 6, 7, 8 and 9. This bracket 50 comprises the brltge portion 51 provided with a thumb screw threaded therethrough and having a shank suliiciently long to engage one of the holes of the spacing bar 30 to hold the latter against movement. The bracket 50 is secured to the frame member at one end by a screw disposed through the apertured car 5-lof the said bracket, said ear 5 contacting with the frame member 5 and spaced from the bridge 51 as by the connecting portion 55 of said bracket. The other end of the bracket 50 is formed a little differently, see especially Figure 9, being provided with an apertured car 56 secured to the bridge 51 by the connecting portion 57 which is of less length than the other connecting portion 55. so that said car 56 is parallel to but spaced from the frame member 5 in order that the securing bar 30 may be passed between said car 56 and the frame member 5 when desired. A screw (30 passed through the apertured car 56 into the f 'ame member 5 will secure said spacing bar 30 within the bracket member 50 as will be readily seen from the drawings.

The operationbf the device is as follows: W hen the opening, such as the window in the drawings, is desired to be closed by the screen 11, the frame holding this screen is swung on the hooks secured to the casing 2. The screw 60 of the bracket member 50 secured to the frame 1 is then removed and the spacing bar inse "ted within the bracket 50 by passing the bar between the car 56 of the bracket and the side member 5 of the frame, whereupon the screw ('30 is then replaced to prevent the spacing bar 30fron1 leaving the said bracket. The frame 10 is then allowed to swing in toward the window frame 1 and the bar 30 turned about the pivot 27 in a downward direction and the foot moved toward the bottom member 16 of the frame 10 so as to have the aperture 36 of the said foot engaged in locked position by the bolt 41. of the latch ll). During this operation the inclined edge 13 at the top of the frame 10 will abut the inclined edge 15 of the casing and likewise the inclined edge 17 at the bottom of the frame 10 will substantially litthe inclined surface 18 of the sill 6. The hooks 20 and the socket members 21 engaged thereby are so disposed that the frame 10 will tightly lit the casing 2 as well as the frame 1. Also the spacing bar 30, the angle member 96, the bracket member 50, and the latch l0 are all so disposed relative to each other that when the screen is in closed position as shown in Figure 2, the bottom of the frame 10 will be in close contact with the bottom frame member elof the window frame, and the intermediate portion of the screen frame 10 to which the angle member 26 is secured will be forced into close contact with that portion of the side members 5 of the window frame to which the bracket is secured.

This drawing of the screen frame 10 into close contact with the window frame by means of the spacing bar 30 is accomplished as follows Vvith special reference to Figures 7 and 8 it will be observed that the cam notch Ell comprises the short inclined surface disposed nearly at right angles to the longitudinal axis of the spacing bar 30, and the longer inclined surface 71 disposed at but a slightangle to the longitudinal axis of said bar. Further it will be observed that the screw (50 is so disposed in the side member 5 of the window frame that the surfaces of the cam notch 31 will normally at all times contact with said screw.

lVith special reference to Figure 7 it will be noted that the frame 10 is advancing toward the window frame, as indicated by the arrows, to occupy its closed position. During this movement the spacing bar 30 will ride on the surface of the screw (50 until the cam notch 31 is reached whereupon the bar 30 by its own weight will cause the inclined surface 71 of said notch to be engaged by the screw 60. Continued movement of the parts shown in solid lines in said Figure 7 will *ause the screw 60 to occupy the deepest portion of the notch 31 thus bringing the parts into the position shown in dashed lines. Figure 8 shows the screen frame 10 in full closed position and from this figure and Figure 7 it will be seen that during the final step of closing the screen frame 1.0 the short inclined surface '70 contacts with the screw (it). During the successive steps there fore in closing the screen 10, it will be seen that the screw (30 serves as a fulcrum for the spacing bar 30 as a lever. That is to say, the free end of the bar 30 becomes the operative end of a lever which when turned about the screw 60 as a fulcrum forces the screen frame 10 into close contact with the window frame 1 due to the spacing of the cam notch 31 and the said screw 60. \Vhcn the fran'ie 10 has contacted with the side members 5 of the window frame as above described, the spacing bar 30 is in a depending position such as shown in Figure 2 and may be then locked in such position as by the bolt 41 of the latch 40. Thus it will be seen that the screw (30 serving as a fulcrum detcrmil'ies the position of the pivot pin 27, as well as the position of the foot 35 of the spacing bar 30 when the screen is closed.

In the modified applicatiom shown in Figure 11, the spacing bar 30, till! angle member 26, and the latch 4-0 have been applied to the cover of a trap, or man-hole. such as are provided in roots. The bracket member 50 is applied to the box farming of the manhole as shown and bears the same relative position to the spacing bar 30 and latch 40 as it did in its application to the window and screen .above described. That is to say, the cover 100 is hinged as at 101 to the box framing .102 in the .roof 103, and the angle member 26 is disposed on the under side of said cover in'such a position, relative to the latch 'also on the under side of said cover. that when the cover is in closed position as shownin solid lines in Figure 11 the foot 35 of said bar 30 may be engaged in locked position by the bolt 4 1.of the latch, exactly as was the case in Figure 2 of the drawings. If desired to open the cover 100 only partially or to a position as indicated in dashed lines in said Figure 11, the thumb knob 52 on the bracket is engaged in such a hole 32 as will give the desired opening of said cover. In every respect the latch 40, the spacing bar 30 and its associated member 26, and the bracket 50 are the same as the latch, spacing bar, angle member and bracket as disclosed above in relation to a window screen, and therefore the operation of these parts is exactly the same as was the operation above described.

In Figure 12 is illustrated a modified form of bracket corresponding to the bracket 50 above described. there is provided a casting comprising a base plate 120 adapted to be permanently secured to the frame 121 of any opening as by the screws 122. Rigidly secured at one end of the plate 120 is the lug 123 and likewise at the opposite end is a similar lug 124. Suitably secured in pivotal relation to the lug 123 as by the loose rivet 125 is the bridge or plate 126 of such a length as will extend from the lug 123 to the lug 124 and which may be secured to the lug 124 as by the screw 127 threaded into said lug. Thus the bridge 126 is secured to the base plate 120 in spaced relation thereto sufficient to slidably= receive the spacing bar 30. Disposed centrally of the bridge 126 is the thumb screw 130 threaded through said bridge and adapted to engage any one of the holes 32 located in the spacing bar 30. The advantage of the modified form of bracket shown in Figure 12 over the bracket 50 above described is apparent but may be briefly stated as follows. The continued removal and insertion of the screw from the bracket 50 in order to allow the spacing bar 30 to be positioned and removed from the said bracket will in time so destroy the material of the window frame as to make it imperative to either locate the screw 60 in a differ ent portion of the window frame or else move the entire bracket 50 to a difierent position thereon. The former contingency would be a serious mistake since the screw 60 serves as the fulcrum for the spacing bar 30 in order to secure the closure in tight relation to the opening.

The construction shown in Figure 12 ohviates this difficulty, in that the bracket 120 In this modificationis adapted to bepermanentlysecured to the frame ofthe opening and only thescrew 127 removed in order to permit the'placement and displacement .of the spacing bar 30. Since the. parts 120, 123, 124, 125, 126 and 127 are all constructed of metal. there will be little if any wear on the parts as will be obvious. In this respect of course the lug 124 serves as the fulcrum for the spacing bar 30 and as its position is always fixed relative to the window casing, the continued removal of the spacing bar 30 will never cause to exist an ultimate state of condition as that described above with the use of the bracket 50 and screw 60. WVith either type of bracket, that is, 50 or 120, it is to be noted that the closure may be retained in an open position by means of the notch 33 in the bar 30, see Figure 10, which will engage with the proper element of the bracket, as clear from Figure 1 of the drawings. That is to say, the notch 33 being at the free extremity of the spacing bar 30 will, when engaged with the screw 60 of the bracket 50, or the lug 124 of the bracket 120, hold the closure in a substantial open position.

It is to be understood that the closure fasteners above disclosed will be utilized in pairs. That is to say, in the use of these fasteners there will be one applied to the left side of said closure and another fastener disposed on the right side of said closure. Stated in still other words, as is well understood, these fasteners will be made in rights and lefts.

It is obvious that those skilled in the art can vary the details of construction as well as the arrangements of parts without departing from the spirit of the invention, therefore it is not desired to be limited to the foregoing except as may be called for by the claims.

What is claimed is:

1.
