SAMUEL SEGAL, 0F NEW' YORK, N. Y.

SASH FASTENER.

Application filed February 5515, 1921. Serial No. 447,691.

To al? whom 'it may concern.'

Be it known that I, SAMUEL SEGAL, a citizen of the Uinted States, and a resident of New Yprk, in the county of New York and State of New York, have invented certain new and useful Improvements in Sash'Fasteners, of which the following is a specification.

My invention relates to sash fasteners andmore particularly to that type of sash faswindow sasha/nd by means of which the sash may be locked in open, closed or partially closed position.. y

The principal object of the invention is the production of a novel sash fastener which shall preferably be of the type hereinbefore referred to and which shall not 'only beof simple construction butwhich shall also be of extreme strength whereby it will effectively perform its fastening function with but slight danger of breakage. y

Other and further objects and advantages of the invention are the provision of a nonrotatable but removable bolt which may be renewed in the event of breakage and the provision of a movable carriage consistingv of a single piecebf material of substantialstrength enclosing and hiding from view Vthe interior and unsightly parts of the device and acting as a protective casing therefor and enhancing both the appearance and strength of the device. v

Referring to the d-rawings showing a practical embodiment of the invention:

Fig. 1 is a side elevation of the sash fastener shown attached to a window sash and in operative position.

Fig. 2 1s a plan view of the device.

Fig. 3 is a horizontal section on the line 3-3 of Fig. 2. y

Fig. 4 is a vertical cross-section on the line 4 4 of Fig. 3.

Fig.-5 is a rear end elevation of the device'.

lReferring in detail to the several figures of the drawing:

1 indicates an upper window sash and 2 a lower window sash`which are adapted to slide towards and away from eachother in suitable guideways (not shown) of a window frame; The base of the sash fastener comprises a metallic angle-piece having an upright or vertical member or post 3 and a lower transverse and horizontal member '4 having wings or extensions 5 .provided be secured to a slidablewith holes 6 adapted to `receive screws 7 i whereby said base may be securely'fastened to the top raillof one of the sashes, as for instance the sash 2. as shown in Fig. 1. 7 indicates a strengthening and supporting diagonal rib connecti.1g together the vertical and horizontal members of the base and I prefer in practice to construct said vertical member, horizontal member and diagonal rib'as an integral structure. The said upright or vertical member 3 is provided with an opening 8 preferably annular, extending therethrough and adjacent 'the top thereof.

9 indicates a bolt, the rear end of the shank of which is rectangular-shaped as shown at 10, said rectangular-shaped portion terminating in a head 11 and having a screw-threaded forward end as at 12. Said bolt is rigidly mounted in the upright member 3 by passing the shank thereof through the annular opening 8 and hammering the head 11 whereby the rectangular-shaped portion 10 will tightly engage. and be jammed within the surface of the opening 8 and the head 11 will engage the rear side of the upright member-B with the shank of the bolt extending forwardly rigidlyl from the upright member. This tight engagement of the rectangular-shaped portion l() and the opening 8 prevents rotation of the bolt but permitsit to .be removed in the event of its damage or breakage for the substitution of" a new bolt by merelyv knocking or hammering the screw-threaded end 12 to release the rectangular portion 1 from its engagement with the opening 8 whereupon the bolt may be withdrawn through said opening.

13 indicates the top wall of a movable carriage, .14 the side gvalls, 15 the front wall and .1G the rear wall thereof. All of said walls of said carriage are preferably cast as a single integral structure of lsubstantial strength, said carriage comprising a hollow housing open at its base as is illustrated. The rear wall 16 is preferably provided with an opening l to provide ease for assembly of the parts and particularly the bolt and to permit headed end 11 of the bolt without taking the sash fastener apart for the purpose of driv- `ing the bolt home" within the opening 8 1n the event of its becoming loose the-rein. The front wall 15 of the carriage is provided with a suitable opening receiving the screwthreaded end 12 of the shank of the bolt, which end carries thereon a thumb-nut' 18.

access to be had to the i spring- ]9 encirclcs said bolt and bears against the upright member or post of the base as well as against the wall 15 ot' the carriage and tends by its action to force the carriage forwardly or away from the upri ,eht member when the transverse member Ll: is fixed or screwed to the sash 2. The carriage, as shown, is mounted on the said.

transverse member t and is movable thereon in a direction transverse to the plane of the upright member 5, said upright member itting intermediate the side walls i4 of the carriage and acting' as a tc'uidc 'for said earyria,f e.

Vihen the sash fastener is in mounted and proper position the member 4f ot the base thereof is screwed to the top rail 01..,the sash 2 as shown in F l. `When it is desired to tasten the window in open, closed or partially closed position the thumb-nut 18 is threaded forwardly towards the sash l which forces the carriage rearwardly against the action of spring; 19 and in an obvious manner whereby the rear wall 16 thereofl will engage and exert a strong pressure against the upper sash l thus causing a binding' action ot" both sashes in the guidein the frame and securely locking said sashes against relative movement. To iin-- lock the sash fastener it is n'ierely necessary to unthread the thumblnut 1S thereby permitting the spring i!) by its action to move the carriage forwardly and release the earriagre Jfrom its engagement with the upper sash l to permit the sashes 'to .be moved t'reeiy.

My improved type or' carriage i'ieing,r composed ot' a single piece solid metal is notsusceptible to breakage and because of its strength it exerts a strong' locking;i pressure against the window sash l. lts peculiar construction permits it to act as a protective coveringf for the interior mechanism of the device, said mechanism not only being protected against injury butag'ainst dust and dirt.

It will. be understood that in some cases l' prefer to mount vand fasten the device on a sash in a position at right angies to that shown and described whereby the rear walt o' the carriage will be forced into locking engagement with the side of' the window frame inst :d of with second sash so that the Yfastener when in operative position, will' hold against movement only the sash to which it is 'fastened while pernntting treedom o' movement oi the other sash it one' obtains. The term second window sash in the appended eiaims will therefore be understood to also include the trame or other part oi? the window.
