The present invention relates to improvements in closure fasteners and has reference more particularly to a device for fastening the upper and lower sliding sashes of a window either in a closed position or in any vertically adjusted position with respect to each other.

One of the important objects of the present invention is to provide a window fastener of the above mentioned character that can be readily and easily attached to the upper and lower sashes of a window without necessitating any material alterations of the parts of the window and which will not furthermore interfere with the vertical sliding movement of either of the sashes, when the sliding bolt is in a retracted position.

A still further object is to provide a window fastener of the above mentioned character which is simple in construction, inexpensive, strong and durable and further well adapted to the purpose for which it is designed.

Other objects and advantages of the invention will become apparent from the following description taken in connection with the accompanying drawing.

In the accompanying drawing wherein like reference characters indicate like parts throughout the several views:

Figure 1 is a perspective view of one form of the window fastener embodying my invention showing the parts secured on the upper and lower sashes of a window, and

Figure 2 is a detail perspective view of the modification of the keeper bar that is used in conjunction with an upper sash formed with central vertical ribs.

In the drawing with reference more particularly to Figure 1, the numeral 1 designates the keeper, the same being formed from a single piece of metal and being of a suitable length. The intermediate portion of this flat strip of metal is stamped outwardly as il lustrated at 2 and a series of vertically spaced openings 3 are formed in the outwardly bulged portion 2. This keeper is secured to the inner face of the upper sash A at one side edge portion thereof, and the lower edge of the keeper terminates adjacent the lower edge Serial No. 243,236.

of the uppersash. The securing means for attaching the keeper to the upper sash is shown at 4.

My window fastener further includes the provision of abase plate 5 that is secured on the upper edge of the lower sash B of the window adjacent the side edge thereof, and the securing means for the base plate is illustrated at 6. The outer endiof" the base plate is disposed upwardly to provide a'relatively large laterally disposed'ear 7.

A smaller ear Sis struck out fromthe central portion of the base plate 5 and is disposed upwardly in parallel spaced relation with respect to the outer ear 7. The smallerinner ear is formed with a centrally located opening which registersv with a similar opening formed in the outer'ear'7 andthrough which openings is slidable the bolt 9 an actuating linlob '10 being carried onthe outer endof the A notch 11 is formed in theiinner ear 8 and-the same communicates at its inner end with the central opening formed inthe ear. This notch is provided for they purpose of permitting the laterally extending pin 12 that is carried by the sliding bolt 9 to pass therethrough when the bolt is disposed in one position, the pin 12 being located on'the inner end'portion of'the bolt so that whenthe-bolt is retracted, the pin will be disposed against the outer face of the ear 8 and manifestly when'the'bolt is in its projected'position, the

'pin will be disposed on the opposite side face ofthe ear.

An' expansibl'ec'oil spring 13 encircles the intermediate portion of the bolt 9 and is disposed between the ear 7 and a pin l' lthat extends laterally fromthebolt, and this spring normally urges the bolt inwardly so that the inner end of the bolt may be disposed within the adjacent opening formed in the outwardly bulged portion 2 of the keeper 1.

When the slidingwindow sashes A, and B respectively, are ina closed position, the same maybe fastened in such'position' by grasping the knob and slightly turning the bolt 9 so as to position the pin 8 in alinement with the notch 11. The expansible coil spring 13 will then forcethe'sliding bolt inwardly so that the inner end thereof will enter the lowermost opening 8 formed in the keeper, and thereby fasten the sashes against sliding movement.

When the parts are arranged as shown in Figure 1, so that the pin 12 is disposed adj acent the outer side face of the ear 8, the bolt 9 will be maintained in a retracted position and the coil spring 13 will be placed under tension. The window sashes may then be vertically adjusted with respect to each other and when either or both of the sashes have been moved to their desired position, and one of the openings 3 is in alinement with the bolt, the bolt can again be released so that the inner end thereof will engage the adjacent opening in the keeper and thereby secure the windows in their vertically adjusted positions.

In Figure 2 of the drawing, I have shown a modification of the keeper wherein the same consists of a relatively narrow elongated bar 15 that is adapted to be secured on one of the central ribs G that supports the window panes in certain types of window sashes and this keeper bar is formed with a series of vertically spaced bolt receiving openings 16. 7The securing means for the bar is shown at 1 The unit that is attached to the lower sash is of the same construction as heretofore described only that the unit is located at the central portion of the sash so as to be in proper position with respect to the centrally located keeper bar 15.

It will thus be seen from the foregoing description that I have provided a window fastener that can be readily and easily, attached to the sliding window sashes for the purpose of securing the sashes in a closed position or in any vertically adjusted position with respect to each other. A fastener of this character may furthermore be manufactured at a very low cost, and due to its simplicity, may be readily and easily operated.

While I have shown the preferred embodiment of my invention, it is to be understood that various changes in the size, shape and the registering openings in said ears and adapted for rotary and slidable movement on the base plate, the innermost ear being formed with a notch that communicates with the opening formed therein, a pin extending laterally from the bolt and adapted to engage one side of the innermost ear for latching the bolt in a retracted position, said pin being adapted to pass through the notch in the innermost ear when in alignment therewith, an eXpansible coil spring associated with the bolt for moving the same inwardly when the pin is in alignment with the notch, whereby the inner end of the bolt will enter the adjacent opening in the keeper, and an actuating knob on the outer end of the bolt.

In testimony whereof I affiX my signature.

GEORGE L. PARKINS.

arrangement of parts may be resorted to withv V out departing from the spirit of the-invention and the scope of the appended claim.

Having thus described the invention, what I claim as new is a In a window fastener, a keeper for attachment to a sliding upper window sash,-said keeper being provided with aseries of vertically spaced bolt receiving openings, a sheet metal base plate for attachment on the upper edge of a sliding lower window sash andarranged in vertical alignment with said keeper, the outer end of the base plate being directed upwardly to form an enlarged ear, a' smaller ear struck up from the central portion of the base plate, said ears being disposed in parallel spacedrelation and provided with registering openings, a bolt extending through
