WINDCW-SASH LOCK.

To all whom it may concern.'

Be it. known that. I, JOHN DnsDALn, a citizen of the United` States, and residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in W'indow- 'Sash Locks, of which the following iS a slrilled in the art to specification, such as will enable those which it appertains to malte and use the same.

Ilhis invention relates to device-s for lock-v ing the sashes of a window together in a closed position, and the object thereofis to provide an .improved device of thisclass which is simple in construction, eiicient in operation and which may also be used for thefpnrpose of holding the sashes in an open or adjusted position for ventilationv purposes, and which when so used will prevent the sashes from rattling.

The invention is fully disclosed -in the following specification, of which the accompanying dra-wing forms a part, in which the .separate parts of my improvement are designated by suitable reference characters in each of the'views, and in which :f-

Figure l is a perspective view of the cen-n tral part of one side port-ion ofa' window .showingfthe bottom part of the top sash and the 'top part of t-he bottom sash and showing my improved sash lock; F 1g. 2 a transverse sectional view through the sash lock i and that part ofthe top and bottom sashes with which it is connected; Fig. 3 a view showing the operation of the sash lock 1n holding the sashes in' an open or adjusted position, the parts of the sashes being shown parts (l and e, the first of which is secured' in section and parts of the upper sash and the lock being broken away; and, Fig. l a sectional side view of a screw-threaded bolf which forms a part othe sash lock.

In the drawing forming part of this speci- "ication, I have shown at a one side portion of a Window frame, at Z1 a bottom corner portion of the upper sash and at c a top corner portion of the lower. sash. 4

My improved sash lock consists of two to the upper sash and the last to thelovver sash. The part e comprises a base plate e2 having a cent-ral raised transverse port-ion e,

the top of which is provided with a transverse sleeve e4 through which is passed a .threaded bolt. f provided' at yits outer end with a thumbA and finger head f2 and in-v wardly thereof withl a collar f3, and the .in-

provided with a pro- ]ecting'plug g which is countersunk and -secured therein, and which is. composed oi" rubber, or suitable fibrous material, and which forms a projecting nose piece g2, the operation of scribed.

'In practice, the part e is secured on the top bar c2 of the bottom sash o adjacent to the right hand side of the'window frame,

and the part-(Z is secured toa .mortise in' the corresponding side portion b2 of the top sash Z1, and said part Z consists of a .plate havinga central and inwardly dirested sleeve d2 which is threaded interiorly and adapted to receive the inner end of the bolt. f as clearly shown. In the construction shown-in Fig. 3, the inner end portion f4 of the bolt is not threaded nor is the sleeve d2 of the plate d'. The operation will be readilyu'nderstood from the foregoing description when taken in connection with the accompanying drawlng and the following statement. Whenever it is desired to lock the sashes together and lin a'closed position as shown in Figs. l and 2.,*thne bolt f is turned to the right u'n. til the inner end thereof enters the sleeve d2, as shownin F ig. 2. This operation securely bin-ds the sashes together and prevents the moveltlent` of either vertically and also prevents t-heir rattling.

If'it isdesigned to opien the .sashes as shown in Fig. 3 for' ventilation or other pur- -.poses, the bottom sash must be'raised, or the top sash lowered, or both of said sashes may be open after which the screw f is manipulated so as to' force the nose piece l 2'aga-inst the side of the top sash as shown in Fig. 3. This will hold the sashes in the open positio-n and will also prevent their rattling, but it is understood that in this posit-ion of the parte, thesashes are not absolutely locked against vertical move-ment..

lV-ith the inner end portion of the bolt f not threaded and the sleeve d2 of the part d also not .threa.(.l as shown .in Fig. 3, my impro-vement wil still operate asa sash lock solas tov prevent .the vertical movement et' the sashes but the-sasheswill not be drawn togetl'ier as they Wili'whe'n said parts are threa ded as-sho-wn in Fig.. 2.

Although, I have shown my improved sash lock as applied at one side of the window only, it will .be understood that it may be applied at both sides of the window, if

which will be hereafter, de-
