To @ZZ/whom it may concern,.-

Be it known that we, HERBERT C. OETTINGER and JACOB WALLENSTEIN, citizens of the United States, and residents of Cincinnati,

Hamilton county, State of Ohio, have invented certain new and useful Improvements in Fasteners for Sash Meeting-Rails; and we do de- Clare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, attention being called to the accompanying drawings, with the reference-numerals markedthereon,which` form a part of this speciiication.

This invention relates to improvements in sash-fasteners of the kind where, for `the purpose of locking a window, the meeting-rails of the two sashes are locked to each other, and whereby in addition to their locking they are also drawn closely together to prevent them from rattling in windy weather, 'as well as to exclude cold air, draft, dust, duc., the drawing together of the sashes causing at the same time the latch or bolt to become locked in its closed position, and from which itcannot be released until the operation of drawing the sashes together is first and in re- .versed order performed again, which, inasmuch as this operation can only be performed from the inside, defeats the object of any tampering for the purpose of unlocking from the outside.

-,The novel featuresof this invention reside in the general construction, and particularly in that part of it whereby the sashes are drawn together by use for such purpose of the knob whereby the locking-bolt is operated.

In the following specification, and particularly pointed out in the claims, is found a full description of our invention, its operation, parts, and construction, the latter being A also illustrated in the accompanying drawings, in which- Y Figure 1 showsa top view of the two meeting-rails, each provided with its particular partv of the sash-fastener, but not locked yet.

Fig. 2 shows in a vertical section the same parts approaching each other and the fastener locked in dotted lines. Fig. 3 shows in a per;

spective View the parts in the same condition as shown in dotted lines in the preceding tigure. The sashes shown therein as badly titting are, however, now in additio n to their locking closely drawn together. l

. In-the drawings', 6`represents ,a bolt contained in a housing 7, which is provided with [ianges 8, whereby it is secured to the upper sash-rail 9of the lower window-sash. v Within this housing, into the bore of which itclosely tits, this vbolt is capable of a longitudinal movement, and behind it, between its end and the closed end of lsaid housing, there is inserted acoil-spring 10, which imparts to the said bolt a normal tendency to move toward and. out ofthe open end ofthe housing.

11 is a knob secured vby its shank to' bolt 6,

such shank passing for this purpose'through a slot 12 inl the upper part of housing 7, limit- `ing thereby the movement of the bolt and preventing the spring from pushing it out from its position. The other part or catch of the fastener, with which the aforedescribed bolt engages for the purpose of locking the sashes, is` provided with a base 13, bywhich it is secured to the lower rail 14 of the upper sash, Its position thereon is `such as to enable the end of the bolt, which for such purpose projects sufficiently beyond and out of housing 7, to enter a socket or cavity 15 in said catch, within which it 'is held by the pressure of the spring behind it. (See Fig..2.

To facilitate the projecting end of the bolt to enter such socket an inclined surface 16 .is provided above it on the catch, which causes the bolt to move back in its housing, while its end slides over'it, during the approach of the sash-rails, after which, with the latter in position, the restrainedbolt is released, when the compressed spring` now expanding, carries the bolt to its position automatically within the socket of the catch. v (See Fig. 2.) The bolt may also be held back previous to its locking and against the pressure of the spring by turning knob 11 in a-manner-to cause its shank to enter a notch`17, communicating with slot 12. (See Fig. 1.)

For the purpose of drawing the sashes,

closely together, in case they should t badly, and also in order to hold the bolt more securely in its locked position, a hook 18 is provided below inclined surface 16 and tov one side of socket 15, which forms with the upright part of the catch a slot 19. On the bolt there is a pin 20, projecting laterally there- ICO from in such a manner thatas the former is driven into socket said pin passes under the end of hook 18 and into the lower open part of slot 19. There is further provided an additional notch2l, branching ott from slot 12 and located in proper position,whereby`as the shank of knob 11 is turned into it pin 2O is caused to enter slot 19, as may be readily understood from inspection of Fig.A 3. This operation of knob 1l causes the sashes to be closely drawn toward each other by reason of the inclined surfaces 22 and 23, the former on hook 18, the latter on housing 7 and within notch 21. By reason of these two inclined surfaces a compound or double action takes place-to wit: bythe shank of knob 11, which, when coming in contact with surface 23, draws bolt 6 inwardlyand with it the catch, by reason of pin 20, in engagement therewith, and the effect of this action is increased by reason of pin 2O bearing at the same time against surface 22 on hook 18, whereby the Y catch, in addition to the previous movement,

is independently drawn toward bolt 6. Inasmuch as the parts thus drawn together are each secured to a different sash, it follows, of course, that these latter share in such movement and are also drawn closely toward each other. With the parts in such position the bolt cannot be unlocked from the catch until pin 2O thereon is free of hook 18.

Instead of having the inclined surface .16 on the catch the end of the bolt might be properly inclined to facilitate its entrance into socket 15.

For mere lockingpurposes the spring behind th'e bolt might be omitted and the latter be pushed into socket 'l5 when in proper position opposite thereof. lnasmuch as such mode of operation, however, would impose an additional duty on the person closing the windows, carrying with it the liability to be forgotten, it is preferable to retain the spring, whereby the locking operation of the bolt takes place automatically as soon as the sash es are closed.

As will be seen, by utilizing the knob on the bolt, in addition to its usual function, also l for drawing the sashes together, special parts for such purpose are. done away with. The rear end of the housing may be closed, wherebythe actuating-spring is readily confined in its positionand the general construction greatly simplified. f

Having described our inventio ,.we claim as new- 1. In a sash-fastener, the combination of a l housing 7, provided with fianges for attachment and a cylindrical bore closed at one end and open at the other, a slot 12 in the upper bored part of the housing, a locking bolt closely fitting and confined in the bore of the housing, a spring between the closed end of the latter and the inner end of the bolt, an

operating knob 1l on the latter, passing with its shank out through slot 12, whereby the movement of the bolt is limited and a pin 20 on its outer end, a notchv2l branching off `from slot l2, whereby when knob ll is opposite it, a limited rotation of the bolt is permitted, a catch having a cavity or socket 15, in its front-side adapted to be entered by the outer bolt-end and provided with a slot 19 in its side to receive pin 20 after rotation of the bolt, and inclined surfaces 23 and 22, the former in notch 21, the other in slot 19,which by contact with knob 11 and pin 20 respectively, of the bolt when the same is rotated, produce a compound and double action for the purpose of drawing the sashes together. y

2. In a sash-fastener, a catch or keeper, inclined on its'upper surface and adapted to be secured to the sash-rail, a socket or cavity 15 in its front-side below its upper inclined end and a slot 19, in its side, in combination with a rotary spring bolt having a pin 2O at its outer end adapted to enter slot 19 when the outer bolt-end is in position within socket l5.

In testimony whereof we hereunto affix our hands in the presence of two witnesses.

HERBERT C. OETTINGER. JACOB WALLENSTEIN.
