WITNESSE' n Vrh/mh weee' "t,

Be it known that I, Liz-.tcm limo, a citizen of the ilnited fi ailes, residing.;` in the cityv of Newark, in the'connty oi' llsseiranifl State of `New Jersey, have invented certain new and usefulimprovements in @ash-Fasteners, of whichthe 'following is a tall, clear, and exact description, such as'will enable others skilled in the art to .vhicl-i it pertains to makeVconstruct. and. use the saine, reference being; had to the accompanying drawings, and to numerals of reiference marked thereon, forming;l a part of this specification. 1

My invention relates to improvements in sash fasteners, and thev object ot my invent-ionisito pron'iote security in the use of window sash fastenings..

A further object ot my invention is the production. of a sash fastener which shali he simple in construction, coxnparativeiy inexpensive in cost, and vwhich will hold the sashes securely whefi'aeled, andy when :re-v

leased, will perlnit the sashes to he moved npgurearh other freely.

WV ith this end in View, my invention con-.

' sists in certain novelties ot construction and arrangements of parte, as hereinafter set forth and pointed out in the claims.

While the preferred forms of my ini/ eni tion 'are illustrated in the accompanying.

drawings, yet .it is to beunderstood that minor detailchanges maybe matie without departing from the scope tllereot.- 4

In the drawings forming,` a part hereoi, Figure 1 represents a side elevation of my improved device, shown as fastening. the

sashes of a Window, the sashes being shown in section. Fig. 2 represents a pian view ot' .thev same; and`'-Fig. 3 represents e' side ele'- vatlon of my vimproved device, ,detached :from the sash,` showing the parts thereof in 1unlocked position, so asto permit the I,sasi'ies to he moved upon eachother freely.

Similar numerals of referencel indicate like parts throughout the specication and Specification of Letters LPatent.

the pirotetl .latch t3. These parte may he 'formed ot any suitable material, and may he made ot any desirable size.

The supporting bracket 4 is provided with two pivot lugs i extending npifvardly there troni, providing` a space between said ings for the reception of one end of the fastening bar represents a pivot, hy means of which said har is pivotally seenredto the snpporting); bracket 4i.

The front portions of the two pivot .lags are each provided. with a recess D, preferaoiy carved and extending' inwardly from the peripheral edges ot' sa id ings l0, fortl1erecep tion of the holding' lugs l0, formed on tiret iorward rnd oi the pivoted latch f3, presently to he described. 'The piveted fastening; har 5, at one end, is provided with an 'termed on the fastening;n har 5, the .stop l2 designed to engage with the supporting;v

bracket -l-, to limit the rearward movement of the fastening har and the stop 13 designed to he engaged with the sides of upward movement thereof.

rlhe pivoted latch t3 is preferably formed from 'a single piece of suitable material, the. forward ends et which are provided with holding;l lugs 10, having' a shape corresponding with the recesses 9 formed in the lne,r and with which they have locking engagement. The pivoted latch (S is further provided with two pivot lngrs lit extcndingi;` upwardlythere'iiron'i, providing a space be- -tween said ings for the .reception of the fastening har 'ihe construction oi" the holding ings l() of the pivoted latch 6, to-

gether with the recesses 9 'formed in the 1i. snitahie integral finger'piecev 1G is formed on the end of the pivot-ed latch t3, by means of which the same can be readily and conveniently manipulated.

Assuming the parts to be in the locked position as indicated iny Fig. l of the drawings. in order to unlock and permit the sashes to be moved upon fach other, the operation of my device is as follows: The two holding lugs 10 of the bifurcated pivoted latch (i are disengaged from the recesses t) formed in the two pivot lugs 7, by swinging the latch around its pivot '15, and exerting upward pressure upon the linger piece 16, until the side of the pivot` lug 14 engages with the stop l on the fastening bar 5. thereby limiting the upward movement of said pivoted latch. Further pressure applied to the finger piece 1G of thel latch (i, will permitI the fastening bar 5 to be swung in an upward direction around the pivot 8. until the stop 12. which. is formed on the fastening bar 5 engages with that portion of the top surface of the bracket t which is located between the two pivotl lugs T. thereby limiting the rearward movement of the fastening bar 5 with its attached pivoted latch as clearly indicated in l"ig 3 of the drawings; thereby permitting the sashes to be unlocked. so as to permit the same to be moved one upon each other.

rlhe present invention provides a very efficient and exceedingly simple sash fastener` the same being constructtal to a minimum mnnber of parts and reduced to the simplest operative etliciency` said parts being of such shape as to lend themselves readil to manufacture by the. use of snitable punches and dies from ordinary sheet metal.

llxperience has demonstrated that theI organization above described 'is a highly efficient one. and while the-device described is the preferred embodiment of my present invention, I do not care to restrict myself to the exact details of construction. combination and arrangement herein set forth, it bein(r obvious that minor variations thereof. not involving the exercise of invention, may he made by any skilled mechanic, and such departures from what is herein described and claimed. I consider within the scope and terms of my claims.

Having thus described my invention, what 'I desire to secure by Letters Patent is-zl. In av sash fastener, a suitable base provided with pivot lugs extending upwardly therefrom secured to the upper sash, a fasm tening bar` pivotally secured to said base, said fastening bar being provided with an elongated bearing surface adapted to engage with theI lower sash. a latch pivotally secured t0 said fastening bar adjacent to said bearing surface and adapted to have locking engagement with said base.

2. ln a sash fastener. a suitable base secured to the upper sash provided with pivot lugs extending upwardly therefrom. said pivot lugs being provided with recesses extending inwardly from the edges of said lugs, a fastening bar. one end of which is received between said pivot lugs and pivotally secured thereto.- said fastening bar being provided with an elongated bearing surface adapted to engage wit-h the lower sash, a latch pivotally secured to said fastening bar adjacent. to said bearing surface,

said latch being provided with holding lugs formed on the forward end thereof. designed to have locking engagement thereT with. and stops located on said fastening bar. one of which is designed to engage with the supporting bracket to limit the rearward movement of the fastening bar and the other of which is designed to be engaged with the pivoted latch to limit the upward movement thereof. v

3. ln a sash fastener. a suitable base provided with recesses secured to the upper sash. a fastening bar pivotally secured to said base. said Jfastening har being provided with an elongated bearing surface adapted to engage with the lower sash, a pivotally mounted latch provided with means designed to have locking engagement with the recesses in said base and stops located on said fastening bar designed to limit the upward movement of said bar and saidpivoted latch.

This specification signed and witnessed this 25th day of January. 1916.
