, FASTENERFOR MEETING-RAILS OF ssHs.

SPBCIPIOATION forming part ofn Letters Patent No. 381,2170, dated April 17, laas.

' lApplication inea september 15, 1881. serai No.249so1. (No model.)

of Honolulu, Hawaiianlslands, have invented a new and Improved Sash-Fastener, ,of which the following is a full,clear, and exact description.

l My invention relates to an improvement in sash-fasteners; and it has for its obj ect to provide a device,where'by when theupper rail of the Ilower sash and the lower rail of the upper sash are brought in proper registry the twoA sashes will. be automatically locked, and wherein when thesashes are locked they canor similar instrument. l

The invention consists in the construction and combination of the yseveral parts, as will be hereinafter fully set forth.

Reference is'to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding partsjn all thelfigures.

Figure 1 is a perspective yView; Fig. 2, a side elevation, partly in section; and Fig. 3 is In carrying out the invention, upon the upspaced standards A are attached,through the medium of an integral horizontal base-plate, a,which standards are preferably made with a, concaved rear edge, a', and a perpendicular frontedge, and are further provided with aligning horizontal recesses b, produced 'in the aforesaid perpendicular or front edge near the base-plate. Y

Between the standards A, at the' top, a lever,r]3,y is pivoted, provided with Va weighty projection, b', at the rear, the inner longitudinal edge vof which projection at each side is cutaway to form the yconvex shoulder b2, adapted to engage vthe concave surface a of the standards and limit the inward throwr of the lever. v a l That portion d of the lever B projecting inward beyond the standards is adapted,rwhen in its normal position-Athat is, when the over the upper railof thelower sash,as shown substantially oval in shape and provided with a transverse locking-pin, d', extending horiv zontally outward at each lside, for a purpose hereinafter set forth. "The majorlportion of the leverB, including they inner end, is prefer-- ably recessed centrally, as an ec'onoxnicmeas#y 5 5 ure,and also to render the same as light as'pos!V sible consistent with strength. 'A v Upon the upper surface ofthe top rail ofthe Y lower sash a plate, E, is secured, in substantial j alignment withthe base-plate a, provided with y6o lugs e, to which a U-shaped finger-plate, E', is pivoted, adapted to face the 4standards A and receive betweenits membersthe inner'end of the leverB. v y

rlhe members of thefnger-plate attheirextremities are weighted,"and inclined upon the upper face, in order that normally the said f `extremities,will rest Kupon the plate E',thus imparting a downward and outward inclina- 'tion to the entire finger-plate. Centrally the 7o members of the inger-plate-and above thek p pivotal point vertical and integral studs -h are f- ,provlided, adapted to constitute a barrier 'for the pin d should the lever B be inadvertently f pressed outward. The outerledges of the stud 7 5 are convexed, the convexity extending from Y topto bottom. ,A Y', j In operation, thed windows being locked, as' in Fig. 1, to lmanipulateeither the Iupper or lower sash, the-inner end ofy the ngerfpiece is 8:, pressed down,which causes the studs k to lpassl under the locking-pin d,and.thelever B is'` then pushed outward,the finger-piecebeing released until the pin enters the horizontal re' Y fcesses b inthe standards, thelever assuming .85`

the position, indicated in dotted lines, Fig.` 2. Either sash may then be raised or lowered at will. 'When the sashes ,are brought totheir normal or-closed positions, the weight at .the

rear ofthe lever Br automatically forces the go y inner end thereof over the plate E. As said end is oval, but little friction is produced, and forces the pin'd over the conyex surface ofthe f studs h, tilting the nger-piece inward at the same time.V As soonias the finger-piece isre- 95.

lieved frompcontact with the pin itreturns to its normal position, and the said studs effect-l ually prevent the pin from passing back,even if the 4lever is pushed out, unless ,the ngerp plate is manipulated.

It will thus be observed that whenthewin-y dows are closed they automaticallylock themi ,Y

selves, and that when being closed there will be no danger of leaving them unlocked, as the fastener locks automatically.

Having thus described my invention, Iclaim as new and desire to secure by Letters Patent- 1. In a window-fastener, the combination, with a standard provided with a horizonal recess in the lower front edge, and a horizontal base and a lever pivoted in said standard, provided with a weighted projection upon the outer end, and an oval-shaped inner end having alocking-pin secured transversely therein, of a U- shaped finger-plate pivoted upon a horizontal base, having the extremities of its members weighted and provided with vertical studs above the pivotal points adapted to engage said lockingpin, substantially as shown and described, and for the purpose herein set forth.

42. In a windowfastener, the combination,

with a standard having a concaved outer edge and provided with a horizontal base, and a horizontal recess in the forward edge near said base, a lever pivoted in said standard, pro- .to operate substantially as shown and described.

JOHN EDWARD BROWN.
