FRANK JENISON MAIN, OF MADISON, WISOON SIN.

FASTENER FOR THE MEETING-RAILS OF SASHES.

SPECIFICATION forming part of Letters Patent No. 424,990, dated April 8, 1890. 7

Application filed November 23, 1889. Serial Ila-331,294. (N0 model.)

T0 on whom it may concern:

Be it known that I, FRANK J ENISON MAIN, a citizen of the United States, residing at Madison, in the county of Dane and State of WVisconsin, have invented certain new and usefullmprovements in Sash-Locks; and I do declare 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, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

Figure 1 is a front elevation of a portion of a window with my improved sash-lock applied thereto. Fig. 2 is a vertical section of the same on the plane of line 1 1. Fig. 3 is a vertical section on the line on m of Fig. 1. Fig. 4 is a top view of the locking-bolt.

The object of my invention is to produce a simple strong automatic locking-bolt which, in connection with an automatic clasping device, m'ay be readily attached to windowsash.

A is the window-frame.

B and B are the upper and lower sashes.

G is the bottom rail of the upper sash.

D is the center bar of the sash.

D D are panes of glass.

011 the top of the lower sash, and in line with the center bar D of the upper sash, is secured by screws a a the standard E, in which slides a loose locking-bolt F, and from the upper end of which hangs a pendent bolt-keeper G, so as to bear upon the outer end of the sliding bolt F, the standard being perforated near its top at b for the reception of the pivotal end of the pendent boltkeeper and at c for the reception of the loosely-sliding bolt F. The head 6 of this bolt is triangular, as shown, and a triangular recess cl is cut in the front face of the standard E for its reception.

A keeper fwith an incline on its upper and a shoulder on its lower end and one or more keepers h with inclines at both ends and a recess or socket between them are secured to the upper sash directly in line with bolt F, as shown in Figs. 1 and 2. The bolt F is long enough to project underneath the keeper f or into recess 9 of the keepers h.

To draw the sash together closely at the same time that they are automatically locked, an upright wedge-shaped tongue of metali is secured to the top of the bottom rail G of the upper sash, and a clasp k, with a wedgeshaped open mouth, is secured to the upper rail of the lower sash. When they come together, they hold the sash close together laterally, while the bolting device prevents any Vertical movement.

The pendent bolt-keeper is made in the form shown in the drawings, havinga curved cut-away portion on its inner face Z as a bearing-surface for the head of the bolt F, and inwardly-inclined sides next to the expanding triangular head of the bolt, so as to receive, in connection with the bolt, the pressure of the thumb and one finger of the operator when unlocking the bolt or setting the sash.

These devices are supposed to be attached to sash that are suspended and move freely. When in position, the pendent bolt-keeper is hearing automatically all the time on the head of the sliding bolt and pressing it against the sash. The automatic operation of the devices takes place as the sash come together. The pendent keeper allows the bolt 'to slide over the incline of the keeper f on the sash, and after passing forces it underneath its head, the tongue 11 at the same time being hugged by the clasp la, and the sash are locked against both side and vertical movement. There may be one or more of the keepers h secured to the sash, and thus admit of their being locked at any desired height. The bolt, hOW6Y91,Wlll not enter the recesses only when the sash are moved slowly.

It will readily be seen that my device is simple, strong, and easily applied to the sides or the center of any window-sash. No springs are needed, and the locking bolt with its pendent keeperperformtheirindividual functions separately, and the locking is done antomatically as the sash are moved into the desired positions.

What I claim as new, and desire to secure bo1t-keeper G, with keepers h, with inclines 10 by Letters Patent, is- I at both ends and intervening socket, as and 1. An automatic sash-look consisting, of a I for the purpose set forth. standard E, with a loose sliding bolt F, and In testimony whereof I ailix my signature in 5 a pendent Weighted bolt-keeper G, attached presence of two Witnesses.

as shown, in combination with keeper f, as FRANK JENISON MAIN. and for the purpose herein set forth. \Vitnesses:

2. The combination of standard E, provided GEORGE 0. MAIN,

with the loose sliding bolt F and pendent E. S. MCBRIDE.
