SASH-HOLDER.

SPECIFICATION forming part of LettersPatent No. 461,16'7,dated October 13, 1891.

Application tiled May l2, 1891.

To all whom it may concern:

Be it known that I` DANIEL WILLIS GAS- KILL, a citizen of the United States, residing vat Little Rock, in the county of Pulaski and purpose specilied, which can be cheaply constructed, put together without separate fastenings, and which Will be convenient of operation.

The improvement consists of the novel features and the peculiar construction and combination of the parts, which will be hereinafter more fully described and claimed, and which are shown in the annexed drawings, in which- Figure lis a perspective view of a cornbined sash lock and fastener embodying my invention, parts being broken away. Fig. 2 is a cross-section of the invention near the rear end of the case, showing the escutcheon and the key. Fig. 3 is a central section taken at right angles to Fig.- 2. Fig. 4 is a central horizontal section of the device. Fig. 5 is a modification.

The case F is closed on three sides, the front and rear ends being left open and the intermediate side being closed by the removable plate g. The extensions f at the endsof the case overlap the mortise in the stile of the sash and are apertured to receive screws or other fastenings, by means of which the device is secured to the said stile.

The blockD is recessed in its rear side and is placed in the case and is free to move backV and forth therein, being advanced or pushed forward in the case by the eccentric A, which is j ournaled at its ends in the sides of the case. The front side of the block curves in between its top and bottom ends and the bindingroller B is held in the middle of the block by the spring C, which is fastened at one end to the case, the other end of the spring curving up and confining the binding-roller B between it and the curved side of block D. Agroove or channel K is formed transversely across the face of the block D midway between its ends, in which is fitted a strip of rubber or similar elastic material 7c. The spring is centrally located between the sides of the case and Works through a slot d in the loiver end of block D, and its upper end enters an an.- nular channel bin the binding-roller, so as to come below the surface of the said roller and not interfere With its free action and op` eration. The recess in the rear side of block D is sufficiently deep to form guide-arms CZ d, which retain the block in an operative position against all strain. One journal of the eccentric is provided With an angular-shaped recess E in its end to receive the key H, by means of which the said eccentric is rotated to press forward the said block D. The key is transversely apertured at its outer end and is held in the escutcheon I by means of a shoulder and the ring J, the latter passing through the said aperture in the end of the key. The eccentric is provided With a series offlat faces m, which in the operation of the invention bear against the rear side of the block D and hold the eccentric in the located position against accidental displacement.

In Fig. 5 the parts are precisely the same as shown in the other figures, except that the groove K and the elastic strip k are dispensed with and the eccentric A is circular in form instead of being provided With a series of flat faces m.

All the parts are cast except the spring C, and when assembled occupy the relatedposition shown most clearly in Fig. 3.

The device is essentially a mortise-lock and fastener, and the escutcheon is fastened on the outside of the stile and retains the key in proper relation to the eccentric. To fasten the sash, the eccentric is rotated until the binding-roller Bis jammed between the casement and the block D. In this position the sash is locked against movement in either direction, because a movement of the sash in either direction, would cause the roller B to ride on the incline above or below, as the case the binding-roller normally held against the said elastic strip, substantially as described.

2. In a sash-lock, the` combination, with a block having its face depressed between its ends, of a roller and a spring for holding the roller against the said block and in the lowest part of the depression, substantially as described.

3. In a sash-lock, the combination of the block having its face depressed between its ends and having a recess in its rear side, a binding-roller normally held at the lowest point in the said depression, and an eccentric located in the recess in the rear side of the block directly opposite and in line with the said binding-roller, substantially as and for the purpose described.

4. In a sash-lock, the combination of the' block D, the binding-roller B, and the eccentric A, having a series of iiat faces, substantially as and for the purpose described.

5. In a sash-lock, the combination, with the movable block, the binding-roller, and the eccentric having an angular-shaped recess lin its end located in a mortise in the sash, of

the escutcheon I, the key H, having its inner end fitted in the said recess E and having a shoulder to bear against the inner side of the escutcheon, and a ring passing through an opening near the outer end of the key to confine the escutcheon between the said shoulder and the key, for the purpose set forth, and serving as a means to rotate the key and the said eccentric, substantially as described, for the purpose specified.

In testimony whereof I affix my signaturein presence of two witnesses.

DANIEL WILLIS GASKILL.
