Application filed October 28, 1908. Serial No. 459,910.

To all whom 'it may concern.'

Be it known that I, EDWARD F. KArUs, a citizen of the United States, residing at St. Joseph, in the county of Buchanan and State of Missouri, have invented certain new and useful Improvements in Combined Sash Locks and Fasteners, of which the following is aspecilication, reference being had therein to the accompanying drawing.

My invention relates to improvements in combined sash locks and fasteners, in which the objects are to provide a neat and substantial mechanism, which will automatically draw together and lock the two sashes of a window, be positive and reliable in its automatically operated movements, and which, to automatically lock, shall be started by but one quickly and easily accomplished movement.

A further object is to combine the parts of a window lock with other parts, in such manner, that a window fastener is formed of said combined parts, whereby said two sashes are automatically fastened and drawn together, in such manner as to allow of the upward and downward movement together, of the thus fastened sashes, and thereby permit ventilation, either below, above, or both below and above said fastened sashes. Also, to so construct and arrange the parts, that they will automatically close the crevice, ordinarily found between the parting rails of said sashes, when either used as lock, or as a fastener, thereby preventing admission of air and dust, and also preventing said sashes from rattling, and to so situate and combine the parts, that they shall, in an ordinary sense, be inaccessible and inoperable from the outside of said sashes, thus providing what is ordinarily termed a burglary proof lock and fastener.

I attain these objects by the mechanism illustrated in t-he accompanying drawing, in which Figure l is a vertical section, eut on the line X X', seen in Fig. 4, showing the parts in locked position. Fig. 2 is a view from the outside, showing the parts in fastened position. Fig. 3 is a top plan, showing the 'parts in both unlocked and unfastened position. Fig. 4 is a bottom plan of the parts in locked position, the parting rails of the sash being omitted, to avoid obscurity. Fio. 5 is a bottom plan of the parts in set position, the parting rails and the lower portion of the catch-bar being omitted, to avoid obscurity. Fig. 6 is the same as Fig. 5, except that the parts are shown in fastened position. Figs. 7, S and 9, illustrate one of the various forms of catch-bars, that may be made.

liiy invention in its preferred form, comprises a case l, provided with a slot 1.', formed in the top thereof; a latch lever 2, slidably and pivotally mounted on said case; a pivot stud 3, preferably formed integrally with said lever, projects downward therefrom, through said slot; a semi-annular cam 1, rigidly secured on the lower end of said stud; a crank-pin 5, projecting from the lower surface of said cam, and preferably formed therewith; a spiral spring 6, having one of its ends pivotally secured on said crank-pin and its other end pivotally secured to the front portion of said case. Latch lever 2 is provided with an upwardly projecting', semi-annular locking flange 7, formed integral therewith, and having an inclined upper surface 9, said iiange and its inclined surface being arranged eccentric to stud 8. Said latch lever is also provided with a hook 8, on one end thereof, and a thumb piece 2, on the opposite end of said lever. Hook S is provided with a sloped surface 9, for deflecting said hook, as hereinafter described. A catch-bar 10 is provided, having notches l1, formed in one edge thereof, and a projection or shoulder l2, formed longitudinally on its outer side. The lower portion of said catch-bar is suitably curved to pass downward outside of bearing piece 18, and is provided with an inwardly projecting sleeve 14:, formed integral with the lower portion of said catchbar, and rotatably secured in aperture lll in said bearing piece, by rivet 15, which passes through the inwardly projecting flange 16, formed on the inner end of said sleeve, and through spring washer 17, and is headed 0n both of its ends. Said spring washer' rests against the inner surface of bearing piece 13, and elastieally draws the lower portion of catch-bar 10 against the outer surface of said bearing piece, thereby providing an inexpensive, substantial and well alined pivotal securing means for securing said catch-bar to said bearing piece, and frictional holding neans, for movably holding said eatch-bar at any desired angle to said bearing piece, when it is desired to rotate said catch-bar, to thereby remove the same from such positions as will obstruct the ordinary operation of cleaning glass 23. Said catch-bar is stopped at erect position by contact of its foot 18, on stop flange 26, formed with bearing-piece 13. Bearing piece 13 is extended inward at its upper end, to form bracket 27, on the end of which is formed the downwardly projecting locking flange 13, adapted to be engaged by the locking flange 7, for locking parting rails 19 and 21 together. Said rails form a part of the respective sashes 19 and 21.

In the installation and operation of my invention, bearing piece 13 is secured by screws 20, at or near t-he center, on the upper surface of the lower or parting rail 19, of the upper sash 19 of any ordinary window, and case 1 is secured in register with said bearing piece, on the upper or parting rail 21 of the lower sash 21 of said window, by screws 22. In practice, the operator, in locking said sashes, by thumb-piece 2 rotates lever 2 from stop stud 1, (seen in Fig. 3,) until crank-pin 5 has thereby been carried to the point, indicated by dotted lines 5, in Fig. 4; after which spring 6 draws said crank-pin to the position seen at 5, thereby rotating lever 2, carrying flange 7 into engagement with i'iange 13, in the position seen in Figs. 1 and 4, which locks rails 19 and 21 together. It will be seen and understood, that the inclined upper surface 9, of flange 7, is carried under, and presses upward against the bracket 27, thereby forcing rail 19 and its sash 19, upward.

Thile the described rotation of lever 2 is taking place, the semi-annular periphery of cam 4 is thereby rotated from the position indicated in Fig. 3, to the position shown in Fig. 4, in which position said cam has its longitudinal movement stopped by the outer wall of case 1, thus forming a rotatable abutment for stud 3 and preventing outward movement of flange 7, which, (due to its position, eccentric to stud 3,) draws flange 13', inward, and thereby draws rail 19 from the position seen in Fig. 3, to the position seen in Fig. 1, thus closing crevice 28, seen open, in Fig. 3, thus tightly and substantially locking the described sashes. If the operator so desires, he may assist spring 6 in its automatic operation, by applying pressure to thumb-piece 2.

To unlock the locking parts, the operator draws thumb-piece 2 overcoming spring 6, unt-il said spring has passed the center of stud 3, after which spring 6 automatically draws the part-s to the position seen in Fie'. 3, with lever 2 stopped against stop stud 1 To fasten and draw said sashes together, in proper position for ventilation, as seen in Fig. 2, thumb-piece 2 is pushed toward catch-bar 10, and rotated until the sloped surface 9, of hook 8, has deflected said hook and has passed said catch-bar, after which, spring 6 draws said hook into engagement with the catch-bar 10, in set position, seen in Fig. 5. IVhen parts are in set position, the raising or lowering of either one of said sashes, brings one of notches 11 in register with hook 8, which is then automatically drawn into engagement therewith, by spring 6, in fastened position, seen in Fig. 6. Spring 6 continues to pull said catch-bar, after being thus fastened, and thereby draws rails 19 and 21 toward each other, and thusprevents their sashes 19 and 21, from rat-- tling.

While I have shown and described my invention in the foregoing manner, it is evident shoulder 12, on catch-bar 10, could be supplemented or augmented in various ways, by the forming of recesses in said catch-bar, without departing from the spirit of my invention, one of such recessed catch-bars being shown at 10b, in Figs. 7, 8 and 9, in which hook 8a is adapted to pass into engagement with shoulder 12a, in set position, seen in Fig. 7 and to enter recesses 12b, and be thereby secured in place when said hook is in notches 11a, in fastened position, seen in Fig. 8. In this latter position, said hook rests in recess 10, formed in the outer side of said catch-bar, for so inaccessibly placing the innerl edge of said hook, in said catchbar, that an unfastening instrument, (not shown,) forced upward through crevice 23, could not be inserted between said hook and catch-bar.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
