FASTENER FOR MEETINGwRAILS OF SASHES.

SPECIFICATION forming part of Letters Patent No. 365,679, dated June 28, 1887.

Application tiled March 10, 1887. Serial No. 230.43.). (No model.)

.t'o all whom, it may concern:

Be it known that I, BERNHARD Ganrnn- BERG, of Oovington, Kenton county, Kentucky, have invented a new and useful Iinprovement in Sash-Fasteners, of which the following is a specification.

My invention relates to a means for fastening to each other the lower and upper sashes, which cannot be shaken loose or tampered with from the outside, and which prevents the sashes rattling.

In the accompanying drawings, Figure I is a perspective View, which shows my sash lock or fastening in its retracted or inoperative condition. Fig. II is an axial section of the same in its protracted or locked condition. Fig. III is an underside view of the bolt, the same being shown in its protracted condition. Fig. IV is a front, and Fig. V is a top, View of my bolt-case adapted for use with sashes, the stile of whose lower member is prolonged upward above the level of the meeting-rail.

1 2 may represent port-ions of a lower and an upper sash, respectively. An auger-hole, 8, in the upper sash receives the boss 4 of socket 5, which is secured by spurs 5" and screws 6 to the face of the upper sash. The auger-hole 3 is excavated deep enough to receive the thicker part 7 of a helical spring, 7 8, whose contracted portion 8 occupies the bore 9 of the socket 5. In the retracted condition of the bolt the portion 8 of the said spring occupies the bore 9 throughout its length, or nearly so, as seen in Fig. I. This spring, yielding to the entering-bolt in the act of locking the fastening, becomes com pressed longitudinally, as shown in Fig. II, and by its resilient force prevents the bolt being shaken loose from its locked condition, and also prevents rattling of the sashes.

10 is a cylindrical case having perforated wings 11 12 for screws 13 14, by which it is at tached to the lower sash. A bayonet-slot, 15, in said case receives a stud, 16, that projects from the side of a cylindrical bolt, 17, which hold the said bolt to its locked conditions (Shown in Fig. III.)

For use with the so-called lugged sashes whose stiles extend above the meeting-rail, as seen in Fig. IV, the shell occupies an angerhole formed for it in the lug, to which it is attached by screws 22 23, that traverse a collar or scutcheon, 24, that projects rectangularly from the shell. An inferior, but nevertheless useful, modification of the above may consist of the described parts, with the exception of the socketspring 7 8. By pressing knob 18, turning it to right, and then releasing, the fastening becomes self-locked. To unlock, again press knob, turn to left, and again release.

I claim as new and of my invention The combination, with an uppersash having a hole in one rail, a socket fixed to said sash and having a perforated boss projecting into said hole, a helical spring bearing at its outer end at the bottom of said hole, havingashoulder bearing inwardly against the said boss, and a contracted portion entering the perforation in said boss, of the lower sash, a casing fixed thereto, and abolt adapted to slide within said casing and enter the bore. of said socket,

whereby the spring is compressed and forms an anti-rattler, substantially as set forth.

In testimony of which invention I hereunto set my hand.

BERNHARD GANTENBERG. Attest:
