SASH-FASTENER.

Specification of Letters Patent.

Patented April 21, 1908.

Application filed June 20, 1907. Serial No. 379,838.

To all whom it may concern:

Be it known that I, CHARLES S. WnIPrLE, a citizen of the Unit-ed States, residing in Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Sash Fasteners, of which the following is a specification.

This invention relates to that class of sashfasteners which are adapted to hold the upper and lower sashes in a closed position, or to prevent the upper sash when'lowered to a limited extent from being lowered still farther from the'outside, or the lower sash when raised to a limited extent from being raised still farther from the outside, so that the space between the upper sash and the head of the sash-frame or between the lower sash and the sill cannot be enlarged from the outside unless such space is sufficiently great to allow the sash-fastener itself to be reached from the outside.

The'invention consists of a new and improved device adapted to be applied to the to of the lower sash and to engage one of the sti es of the upper sash, as fully described in detail below, and illustrated in the accompanying drawings, in which Figure 1 is an elevation showing portions of the up or and lower sashes, with the upper sash owered with relation to the lower sash, and my device in position. Fig. 2 is a vertical section taken on line 22, Fig. 1, looking toward the right. Fig. 3 is a pers ective view of my device, dotted lines slowing portions of the stiles in the upper and lower sashes.

Similar letters of-reference indicate corresponding parts.

a represents a portion of one of the stiles, and b a portion of the meeting or top rail of the lower sash, and 0 represents a portion of the corresponding stile and d a portion of the ,meeting or bottom rail of the upper sash.

.the plate and the slots, the

wardly extending vertical portion 7c integral with the portion 9 and at right angles therewith, the lower end of said vertical portionbeing bent inward at at under the main portiong at an obtuse angle with the portion k. The upper plate p is flat and has its forward or inner end beveled off into chisel-shape s, and said plate is rovided with two elongated slots Z and m ocated centrally and longitudinally therein. A screw 15 is rigid with the main portion g of the lower late or member, and extends up through t 1e slot Z at a slightly rearward angle with said portion g, and a thumb-nut u is in engagement with said screw above the plate p. A short pin 1) extends fromthe ortion g u through the slot m, said slot m eing near tlie rear edge of pin and the screw are so arranged that the rear or outer .edge of the upper plate extends under the lip k, and against the lower plate at the portion where the lip joins the main portion 9.

This lip is at such an angle that the upper plate can swing from a horizontal osition on the lower plate to a considerab e angle above it, the limit of its upward movement being determined by the position of the thumb-nut u on the screw t.

When the device has been placed in osition, as illustrated, the flat portion 9 o the lower plate or member lies on the upper end of one of the stiles e making a part of the sash, the portion It extends down along the inner or rear surface of said stile, and the portion n underlaps the small ledge or shoulder at (Fig. 2) which is found in check-rail window sashes as commonly constructed.

The upper plate or movable member plies against t e stile c in the up or sash. By reason of the chisel-shaped edge 8, if an attempt is made to lower the upper sash with relation to the lower sash or to raise the lower sash with relation to the u per, the plate or member p is forced into t e stile a sufficiently to effectually revent such an attempt from being successful, and the looking may be even more effectual by screwing the nut it against the plate p.

The elongated slots and the pin 1) are for. the purpose of retaining the up er plate with its inner or rear edge under the lip h, whereby said plate can swing and is practically hinged to the lower plate without the employment of a pintle and other portions of an ordinary hinge. Moreover the swinging member 19 can be easily removed by removing the thumbnut u from the screw it. Unless the thumb-nut is screwed with considerable force against the plate p, said plate rests gently against the upper sash, and will allow said sash'to be raised or the lower sash to be lowered. The object of the portions 7c and n is, of course, to prevent any upward or outward movement of the lower plate, whereby the device is firmly held in position, but can be applied and removed without the use of screws or any fastening contrivances.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent is z- 1. The hereindescribed improved sashfastener, consisting of a lower stationary plate or member comprising a flat portion adapted to rest on the up er surface of the lower sash, an upwardly and inwardly bent lip at its rear or outer end, and a downwardly extending portion at its inner end adapted to extend down at the rear of the lower sash and provided with a rearwardly extending lip at its extreme end for engaging said sash; a swinging upper plate or member the rear or outer end of which extends under the lip at the corresponding end of the lower plate, and the front end of which has an edge adapted to engage with the stile, and the main poi-1 tion of said upper plate being provided with a slot; and a screw extending from the lower plate through said slot and provided with a suitable thumbnut,for the purpose set forth.

2. The hereindescribed improved sashfastener, consisting of a lower stationary plate or member comprising a flat, portion adapted to rest on. the upper surface of the lower sash, an upwardly and inwardly bent lip at its rear or outer end, and extending ortion at its inner end adapted to extend own. at the rear of the lower sash and provided with a rearwardly extending lip at its extreme end for engaging said sash;

a swinging upper plate or member the rear or outer end of which extends under the lip at the corresponding end of the lower late, and the front end of which has a elhiselshaped edge, and the main portion of said upper plate being provided. with two elongated slots; a screw extending from the lower plate through one of the elongated slots in the upper plate and provided with a suitable thumb-nut; and a pin extending from the lower plate up through the other slot in the upper plate, for the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
