Specification of Letters Patent. Application flied m 25, 1908. Serial No. 434,736.

Patented April 27, 1909.

To all whom it may concern:

Be it known that I, ARTHUR G. NEUMIEIS- TER, a citizen of the United States, residing at Appleton, in the county of Outagamie and State of Wisconsin, have invented certain new and useful Improvements in Window- Locks, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to improvements in sash locks; and an object of my invention is to provide a. sash lock which will be simple in construction, comparatively cheap in manufacture, durable in use and readily applieable to any window of ordinary construction.

A further object of my invention is toprovide a sash lock which will afiord great security and which cannot be unlocked by parties operating from outside, of the window.

In the drawings illustrating the principle of my invention and the best mode now known to me of applying that principle, Figure 1 is a perspective view showing my new sash lock in place; Fig. 2 is a rear elevation; Fig. 3 is a detail partly in section showing the locking bolt in locking position; Fig. 4 is a view similar to Fig. 3 to show the locking bolt withdrawn; and Fig. 5 is a detail showing the-bolt.

The lockconsists of a housing or casing a having near its bottomoutwardly extending flanges I) through holes in which pass the screws 0 which fasten the ca sing to the upper rail or check rail (Z of the lower sash. The casing u is formed with a chamber e through 1 which extends a locking bolt f.i The latter is slidahly mounted in the front and rear walls of the casing (Figs. 3 and 4) and is provided at its outer end with a pull-ring g. lVithiu the chamber 6 the locking bolt f is provided with a collar 5. between which and the inner wall of the casing is interposed a coil spring 11. The locking bolt is formed with two circumferential grooves 7', 7a, with th walls of which is designed and adapted to engage the free end-m of the locking lever 11., between the other end of which lever and the top of the casing is interposed a coil spring 0. The upper end of the casing is provided with a pair-of lugs 17 which carry a pivot pin 9 on which the lever 14. rocks asan axis or fulcrum. One of-the, side rails 1' 55 of the upper sash is formed with a series of holes 8 each of which may sleeve t.

The bolt f being withdrawn, as shown in Fig.-4, and held in that position by the engagement of the locking lever n with the walls of the groove j, the lower sash may be raised and the free end m Withdrawn from the groove j by depressing the other or spring-controlled end of the locking lever n.

be lined with a [he coil spring 71 will then throw the bolt 7' toward the rail 1-, and when the locking end of the bolt comes opposite the next hole .9, the coil spring i will force the bolt f into the hole 8 and will lock the two sashes together. In the locking position of the bolt f, the groove is will come opposite the free end of the locking lever n; and if the springcontrolled end of the latter be allowed to rise, the free end m will be forced into the groove [17, as is shown in Fig. 3, thereby looking the bolt in its locking position. If the upper rails or check rails of the two sashes be brought on the same level, the bolt f-will prevent the raising of the upper sash.

It will be observed that the action of the locking lever 11?, may be automatic and sowill be the action of the bolt f,- that is, the bolt f being released by depressing the spring-controlled end of the locking lever u, its locking end will be forcedagainst the side rail 1" of the upper sash. And when the locking end of the bolt f comes into register with one ofthe holes 8, the spring 1- will force the bolt f into the hole 8 and at the same time the coil spring 0 will force the free or locking end m of the lever 11, into the groove 70.

suitable face-plate u may he provided to prevent undue wear which might otherwise result from the rubbing of the locking end of the bolt f during the movement of 'the sashes relative to each other.

I claim:

1. A sash fastener consisting of a casing formed with a chamber; a locking bolt formed near one end with a groove, said bolt projecting from opposite sides of said casing and extending through said chamber; a spring which is mounted in said chamber and which tends to force said bolt lengthwise; and a spring-controlled lever mounted on the outside of said casing and having one of its ends adapted to engage in said groove to lock said ho t in position.

2. A sash fastener consisting of a casing formed with a chamber; a locking bolt in botliits locking and its releasing positions. formed near one end with a plurality of ln testimony whereof .I have hereunto set grooves, said bolt extending throu h said my hand at said Appleton this 20th day of chamber and being 'slidably mounted in the May, 1908, in the presence of the two under- 5 walls thereof; a spging1 W%1l(3ll (ils monfnted signed witnesses.

in said chamber an w iici ten s to orce r\ said holt lengthwise; and a spring-con- A ARHHTR NLUMPIS l trolled lever mounted on the outside of said Witnesses: casing and having one of its ends adapted ELSIE Korean, 10 to engage in said grooves to lock said bolt J. I. FRANK.
