Arthur Seversan INVENTOR.

BY MM fiMz Patented Sept. 2, 1952 WINDOW s'ror' Arthur Severson, Milwaukee,.Wis. q Application January 31, 1950, Serial'No. 1 41.425"

1 Claim. 1

This invention relates to a window stop which may be readily mounted in a window sash or other similar structure by inserting it into an aperture drilled to receive such window stop, and more particularly to a spring-actuated window stop for selective engagement in a recess formed in a window frame or like structure.

An object of this invention is to provide a spring actuated window stop adapted to be secured in a window sash or like structure which is provided with spring means continuously urging the window stop into engagement with the window frame.

A further object of the invention resides in the provision of a window stop for locking a window sash within a window frame, which window sash may not be readily tampered with from the outside of the window.

Another object of the invention resides in the provision of a window stop which will positively look a window sash in a given position relative to a window frame.

Still further objects of the invention reside in the provision of a window stop that has parts that can be readily manufactured at low cost and which may be easily assembled to produce a device that is strong, durable, highly efficient in operation, and capable of being made from a variety of materials.

These, together with the various ancillary objects of the invention which will become apparent as the following description proceeds, are attained by this window stop, a preferred embodiment of which has been illustrated by way of example only, in the accompanying drawings, wherein:

Figure 1 is a front elevational view of the invention shown in operative emplacement in a window sash, with parts thereof being broken away to show the window stop in greater detail;

Figure 2 is a horizontal sectional view as taken along the line 2-2 in Figure 1; and

Figure 3 is an exploded view of two elements used in the window stop comprising the present invention.

With continuing reference to the accompanying drawings wherein like reference numerals designate similar parts throughout the various views, reference numeral l generally designates a window sash or like structure which is slidably mounted within a window frame [2 having a plurality of recesses l4 suitably spaced therein for reception of a stop portion l6 of the window stop comprising the present invention. The stop portion It is formed integral with or connected to f {UNI-TED! STATES PATENT OFFICE a shaft I8 of reduced cross sectional area which is slidable within a hollow sleeve 20 inserted, in an aperture 22 in the window sash [0.

The sleeve 20 is provided with an apertured end wall 24. Adjacent the end wall 24 are a plurality of notches 26 which are individually selectively engaged between the bifurcated portions 28 of a bracket 38 of substantially L-shape cross section. The bracket 30 is connected to the sash ill by means of screws 32 inserted through apertures 34 in the side 36 of the bracket 30 opposed to the bifurcated portions 28. A spring 38 concentric with the shaft I8 is positioned within the sleeve 20 and biases the stop portion l6 against the frame [2 and therefor the recesses l4. In threaded engagement with the end of the shaft l8 as at 48 is a knurled knob member 42 which limits the outermost position that the stop portion 16 may attain.

Unlike other devices, this window stop has a great advantage in the installation. As prior art window stops of necessity had to be inserted in the outside of the window frame into a hole drilled in the frame, it was necessary to remove part of the window casing and take the window sash out of the frame in order to insert the prior art window stop.

The present invention does not require removal of the window sash. All that need be required is to drill a hole through the window sash while the window is in situ. The spring 38 is inserted into the sleeve 20 and the shaft is is then inserted into the sleeve 20 within the spring 38. Then the stop portion I6 is positioned within a recess I4 which has been drilled into the window frame I2 through aperture 22. The bracket 30 is then secured to the window sash with the bifurcated prongs 28 in engagement with the notches 28 in the sleeve 20. The bracket 30 thus holds the stop in position.

Since from the foregoing the construction and advantages of this window stop are readily apparent further description is believed to be unnecessary.

However, since numerous modifications will readily occur to those skilled in the art after a consideration of the foregoing specification and accompanying drawings, it is not intended to limit the invention to the precise embodiment shown and described, but all suitable modifications and equivalents may be resorted to which fall within the scope of the appended claim.

Having described the invention, what I claim as new is:

A window stop for locking a window sash to a window frame comprising a cylindrical sleeve having an apertured end and adapted to be inserted in an aperture in said sash, a spring projected shaft in said sleeve having an end slidably extending out of said apertured end and its other end adapted to be projected into an aperture in said frame, a knob on the first named 4 REFERENCES CITED The following references are of record in the file of this patent:
