SASH-FASTEVN'E-R.

SPECIFICATION forming part of Letters Patent No. 702,806, dated June 17,1902.

I Application filed October 30,1901. Serial 1T0. 80,482- (No model.)

To all whmn-it may. concern:

Be it known that I, RICHARD D. LOGAN, a citizen of the United States, residing in the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Sash-Fasteners, of which the followingis a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to that class of sashfastener adapted for use both in holding the pair of sash of a window in closed position and in partially-open position for ventilation. The fastener is so constructed as'to furnish ample retention for the sash in any desired position and at the same time provide adequate security against the operation of the fastener from the exterior of the window while partially open'for ventilation.

Myinvention consists in features of novelty hereinafter fully described and pointed out in the claims.

Figure I is a View, partly in elevation and partly in vertical section, of a window with my sash-fastener applied thereto. Fig. 11 is a vertical cross-sectional view taken on line II II, Fig. I. Fig. III is'an enlarged perspective view of the fastener, the position of the parts thereof being similar to that shown in Figs. I and II. Fig. IV is an enlarged crosssectional view taken on line IV IV, Fig. 1. Fig. V is an enlarged crosssectional view taken on line-V V, Fig. IV. Fig. VI isan enlarged cross-sectional view taken on line VI VI, Fig. IV, illustrating a modification of the bolt-retaining means. larged detail-perspective view of the auxiliary bolt carried by the main bolt of the fasten er..

located at suitable intervals, as seen in Fig.

II, and seated in the window-frame in the groove occupied by the lower sash 2 are socket-keepers 6, located at suitable intervals, as shown in Figs. I and II.

7 designates keepers attached to the uppe sash 3, spaced apart on said sash at intervals corresponding to the locations of the pockets 5 in the parting-strip 4.

8 designates a box-plate mounted on the Fig. VII is an enlower sash 2, provided with a box land containing a recess 10, and 11 is a box-plate mounted on the lower sash 2 in line with the plate 8 and provided with a box 12, the'said plate 11 containing a recess 13.

14 designates a main slide-bolt rockingly mounted in the boxes 9 and 12, provided with a handle 15. The inner end ofthis main slide-bolt is adapted for projection intolthe socket-keepers 6, as seen in Figs. I and IV, for the retention of the lower sash of a window in either a lowered or raised position, according to the keeper into which the bolt is projected.

Extending rearwardly from the main slidebolt 14 is an arm 16, that carries an auxiliary slide-bolt17,'having a tapered point18, that is adapted for projecting througheither of the keepers 7, carried by the upper sash 3, into the pockets 5, contained by. the partingstrip 4, whereby the upper sash is held from movement in any desirable position, according to'the keeper 7 and pocket 5, into which the auxiliary bolt is projected.

For thepurpose of retaining the slide-bolts 14 and 17 and preventing their being retracted from the keepers that receive them by the introduction of an instrument from the exterior of the window I utilize a: retaining: screw 20, that is mounted in the arm 16,which unites said bolts and the pointof which-is adapted to be lowered into the recess 10in the box-plate 8, as seen in Fig.V, and which when so lowered holds said arm from movement, and consequently retains the slide-bolts in their projected; positions.

Instead of using the retaining-screw 19 I mayuse a retaining-key 21 to hold the slidebolts from movement, as seen in Fig. VI. This key is adapted for insertion into the groove 14, extending transversely of the main slide-bolt 14 and adapted to be brought into registration with said groove 13. On the introduction of said keyit will be seen that the slide-bolt is connected to the box-plate '11 thereby and firmly held from movement. The auxiliary slide-bolt 17, being provided with 'thevpoint 18, tapered at the forward face thereof, provides means whereby the upper sash is drawn toward the lower sash on the projection of said auxiliary bolt into a keeper 7, owing to the fact that the tapered face of the bolt bears against said keeper, as shown in Fig. IV, while the bolt is being introduced thereinto.

I claim as my invention 7 1. In a sash-fastener, the combination of a slide-bolt adapted to be mounted on the lower sash of a window for engagement with the window-frame, of an auxiliary slide-bolt parallel to and rigid with said slide-bolt, and keepers carried by the upper sash of the window, said auxiliary bolt adapted to engage said keepers.

2. In a sash-fastener, the combination of a main slide-bolt carried by the lower sash of a window and adapted to engage keepers in the windowframe, of a parting-strip and keepers carried by said parting-strip, of keepers carried by the upper sash of the window and an auxiliary bolt parallel to and rigid with the main slide-bolt and adapted to pass through the keepers carried by the upper sash to engage the keepers in the parting-strip.

3. In a sash-fastener, in combination with the lower sash of a window, a box-plate carried by said sash, a slide-bolt carried by said plate and adapted to engage keepers in the window-frame, of an auxiliary slide-bolt parallel to and rigid with said slide-bolt and adapted to engage keepers carried by the parting-strip and the upper sash of the window, of a recess in said box-plate, said auxiliary bolt provided with a tapered end, and a retaining-screw carried by said auxiliary bolt and adapted to engage the recess and to hold the bolts against movement.

4. In a sash-fastener, the combination with the lower sash of a window, of a box-plate carried by said sash, of a slide-bolt carried by said box-plate and adapted to engage keepers in the window-frame, of a second boxplate, said bolt also sliding therein, of a recess in said second box-plate, of a key adapted to fit in said recess, a recess in said bolt, said key also engaging the recess in said bolt, whereby movement of the bolt is dogged and an auxiliary bolt parallel to and rigid with said slide-bolt and adapted to engage suitable keepers in the parting-strip and upper sash' of the window.
