WINDOW FASTENER.

' Application filed September 2, 1924. Serial No. 735,401.

In the fastening of casement and certain other types of windows", it is custon'iary to mount a latch upon the window sash and arrange a striker plate on the casing or window jamb to cooperate therewith. This ar rangement is undesirable for the reason that it necessitates the displacement of the curtains or screen, if any in order to operate the latch.

It is one object of the present invention to provide a window sash fastener that may be readily operated from the face of the window .casing.

It is another object of the invention to provide a standard device adapted to be fitted to any depth of window jamb withoutmechanical alterations.

It is still another object to provide a device of the character indicated that is simple in construction, economical to manufacture, quickly and easily installed, and highly efficient in its practical application.

In the drawing:

Figure 1 is a plan view of the device in an operative position, a part of the window sash, jamb and casing being shown in section.

Figure 2 is a face view of one portion of the fastener in position in the window jamb.

Figure 3 is a face view of one portion of ltlshe fastener in position in the window sas 1 Figure 4 is a side elevation of the fastener housing with the bolt therein.

Figure 5 is an elevation of the casing plate. J

Figure 6 is an illustration of 'another embodiment of the invention.

Referring more particularly to the drawing, I show at 1 a window jamb with a casing at 2 and a stop at 3, a portion of a casement window sash being shown at 4. At 5 is shown. a striker plate mounted on the edge of sash 4 and provided with an opening 6 having a bevelled edge 7.

The latch proper comprises a plate 8 having opening 9 therein and adapted to be mounted on the face of jamb 1 as shown. This plate has portions of two of its sides bent back upon themselves as at 10 to receive the outwardly turned ends 11 of hous ing 12, the housing 12 having. bearings formed therein as at 13.

' In the bearings 13 and within the housing'12' is revolubly mounted element 14 carrying a finger or bolt 15 bevelled as at 16 to engage the bevelled edge 7 of opening 6 in striker plate 5.

In the present case element 14 has a square orifice 17 passing therethrough in concentric relation to its axis of rotation. Slidably mounted in orifice 17 is a square rod 18 terminating at one end in an enlarged cylindrical portion 19 and a handle 20.

4 A plate 21 is provided for mounting parts 1820 on the face of the window casing, the portion 19 of the rod engaging an orifice 22 in said plate. At 23 I show a groove formed in and encircling portion 19 of the rod a distance from the handle 20. When the plate 21 is in position on the rod a portion 19 to bear against the inner surface of plate 21, the outer coil 25 of the spring being of less diameter than the re maining coils and snugly engaging the groove 23, thereby obviating the necessity of providing a pm or other stop for this end of the said spring.

This latter arrangement provides a simple, economically constructed means for maintaining the rod and handle in. osition in the plate 21, and also secures su c'ient friction between the plate and handle to maintain the handle in any position in which itmay be placed.

In assembling the device the element 14 is inserted in housing 12 and then the edges 11 of said element are sprung into engagement with parts 10 of plate 8, the said parts 10 being pinched into engagement with edges 11 and making the plate and housing into one integral whole.

A hole 26 being bored into the casing parallel with the face of jamb 1, and plate 8 and parts carried thereby secured in position, the rod 18 is inserted'in the rectangular orifice 17 of element 14 and the plate 21 secured in position on casing 2.

By making rod. 18 of a given maximum length the devices may be made up in quantities and precisely the same, as the sliding engagement of rod 18 with orifice 17 will permit any required spacing of the plate 8 from the casing 2.

In Figure 6 I which a flexible rod or cable 27, is used instead of the ordinary rod 18.

A flexible connection of some nature between the element 14 and handle 20 may be show a construction inspring 24 is slipped on to the cylindrical fill desirable in cases where it is inconvenient or difficult to arrange the handle in axial alignment with the orifice 17 in element 14.

By combining the flexible rod with the sliding connection between the rod and the element 14 a construction is provided that of the appended claims.

I claim 1. In a device of the character described, a

latch mountable in a window jamb, a plate mountable upon the window casing, a rod engaging said plate and latch and actuating the latter, and a handle for said rod, 'sai .od having an annular groove formed therein a distance from said plate, and a spring mounted upon said rod and engaging said plate at one end and having a spiral of reduced diameter at the other end forengaging said oove.

2. In com ination with a window jamb having a passage formed therein parallel with its face and communicatin with the lace of the window casing, a late mounted in said jamb and intersecting said passage,

a plate having an orifice formed therein mounted upon the window casing with the orifice in alignment with said passage, a handle, a rod carried by said handle and engaging the orifice in said plate and slidably engaging said latch and actuating the same, said rod having an annular groove formed therein a distance from said late, and a spring mounted on said rod and aring against said plate and having a coil of reduced diameter for engagement with said groove.

3. A sash fastener including a housing mountable in a window jamb, a latch journaled therein, a handle mountable upon the window casing, and means 0 erated by said handle and having a sli ing connection with said latch for operating the same, said means being yieldable to permit the placing of said handle out of axial alignment with said latch. ,7

4. In a device of the character described, a revoluble latch operating rod, a supporting plate therefor, and a handle for said rod, said rod having an annular groove formed therein a distance from said plate, and a spring mounted upon said rod and bearing against said plate at one end and having a spiral of reduced diameter at the other end for engaging said groove,
