SASH -FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 310,930, dated January 210, 1885.

.Application filed July 1S, 1884.

pecially for windows where the upper sash is stationary and the lower sash only is fitted to slide, without, however-,being counterbalanced by a weight, sashes so arranged being common in many places in all sections of the country.

The invention will be hereinafter fully described, and specifically pointed out in the claims, reference being had totheacconipanying drawings, in which- Figure l represents a vertical section of a portion of a window-frame and of the whole lowervsash and part of the upper, the sliding sash being iu the lowest or closed position, and locked in the said position by mypresent device. Fig. 2 is a section exactly similar to Fig. 1, but showing a different Inode of applying the fastener. Fig. 3 is a front or face view of the fastener itself. Fig. 4 .is an edge view of the same, partly in section on theline x x of Fig. 3. Fig. 5 is the face view of the washer used to keep the pivoting-screw of the fastener from turning. Fig. 6 shows the reverse side of the fastener, or as seen from the sectional line y 1/ of Fig. 4. iu the direction of the arrow 1, andshowing the manner in which the fastener is heldin a position out of contact with the sash to prevent the raising or lowering of the latter.

A is the side ofa windowframe.

B is the upper stationary sash, and C the lower or movable sash.

D is the fastener, being formed of a stein, a., having at one end oppositely-arranged lateral projections b, which serve as the stops or catches proper, as will presently appear, the whole forming the general appearance of the letter T. The other end of the stem a has a hole, c, bored through it to receive the shank of the screw d, by which the fastener D is pivoted to the side frame, A, of the window in such a position relative to the sash that the one or the other of the lateral projections Z1 (No model.)

may be made to engage the upper edge of the sash to prevent it from being raised from the outside, or to engage with the lower edge of the sash t0 temporarily retain it in the raised position when desired for ventilation o r other purposes; or the fastener may be swung out to bring both projections b out of contact with the sash, so as not to interfere with the raising or lowering of the latter, as shown in the dotted position marked D in Fig. 2.

C and D" indicate, in dotted lines in Figs. l and 2, the position of the sash C and fastener D when the former is held in its raised position by the latter.

The fastener may be arranged, as in Fig. 9, to engage the sash-frame by the angle between the stem a and lateral arm b; but as the weight of the sash or the pressure due to an attempt at raising it in that case tends to turn the fastener upon its pivots, and thus cause eXtra strain upon the locking device, presently to be described` I prefer the mode of applying it which is shown in Fig. l, where the pressure or weight of the sash acts more directly against the pivot, and cannot turn the fastener out of contact.

To prevent the screw d from turning after being screwed into the frame A to the proper depth, the shank of the said screw is Jliled down to form at opposite sides fiat surfaces e, and a little plate or washer, E, provided at one edge with a slot or notch, c', suitable to embrace the thus reduced portion of the serewshank, is applied, as shown in Fig. 4, to engage the said reduced portion, and is then secured to the window-frame by a screw, e2.

A small spring, F, secured in a recess on the inner side ofthe fastener D, engages,when the fastener is turned iu its upper, lower, or intermediate position, a correspondingly arranged, reduced, or iiattened surface, f, upon the shank in a manner which can be understood at a glance with reference to Fig. 6.

To lock the shank c and bolt D together against extra resistance in the two positions in which the fastener acts to support or locks the sash, I provide in the opposite upper and lower circumferential edge of the head ofthe screw d a flattened recess, g, (shown in Figs. 3 and 4,) and arrange in ahole through the shank a, parallel with the shank ofthe screw d, a sliding bolt or knob, H, having a flattened surface, h, which engages the one or the other ofthe aforesaid recesses g, as shown in 'Figs 3 and 4.

The sliding bolt or knob H is pressed outward by a spiral spring, G. To nnlock the fastener from the upper locked position in which it is shown in Fig. 4 and bring it into the lower locked position, it is only necessary to press the knob II inward untilont ot' contaot with the surface g; then turn (by a special handle, I, or otherwise) the fastener half a turn around until, by the action of the spring G, the lift h engages the lower recess, y, in the screw-head.

Itis evident that by arranging in different places upon the sash-frame a cleat, stop, orangularbracket, suitable to engage theproje'ction b of the fastener B, the sash maybe held at different points of elevation when desired.

Having thus described my invention, what I olaiin as new, and drsireto secure by Letters Patent, is

l. A sash-fastener consisting of a shank, a,

adapted to be pivoted to a window-frame, and l provided Wlth opposite lateral projections b,

arranged to engage as stops to a sliding \vin doWsash by turning the fastener uponis pivot into one or the other of two positions, as hereinbefore set forth.

2. In a sash-fastening device. the combination of the pivoted T-shaped fastener D, provided with the spring F, with the pivoting Screw d, having reduced or iiattened portions f, to engage the said spring for the purpose of temporarily retaining` the fastener in position in or out ot Contact with the sash-frame, substantially as speeied.

3. In a pivoted sash-fastener, D, the combition ot the stationary pivoting screw or stud d, havin upon its head flattened portions g, with a shank, a, having in a bored or soeketed portion adjacent to the pivoting-screw a springpressed sliding knob, II, provided with a lip or flat surface, h, arranged to engage and interlock with the said flattened surfaces g upon the screw-head, to prevent the fastener from turningron its pivot, as hereinbefore set forth.

at. The combination of the pivoted sash-fastener I), provided with a sliding knob, H, arranged to engage and interlock with the pivoting-stud, the pivoting-screw d, having upon its shanks opposite reductions'e, and t-heplate or washer E, provided with a notch, e', to engage the reduced portion of the said shank, the said screw d and plate E being both seenrable to the saine frame, A, as and for the vpurposes hereinbefore set forth.

ln testimony that I claim the foregoing as my invention I have signed my naine, in presence of two witnesses, this 7th day of June, 188i.
