Specification of Letters Patent. 3 2 l-Qtdzented Apr. 18, 1916 Application filed January 2, 1915. Serial No. 190;
- beenthe custom to fasten-window blinds by the troubles and disadvantages from the use thereof, such troubles as disengagement from the catch and consequent banging of the blind.
The object of my invention, therefore, is to provide a mechanism or catch which will be positive in its holding functions and ease will eliminate the objectionable features hereinabove referred to.
Another object of my invention is to provide a blind fastener of such a c0nstruc- I tion that the blind will so easily engage its manipulation of fastening the blind.
catch or locking mechanism that an unskilled person will have no difiiculty in the In fact, the fastener of my invention is practically automatic in its action of locking, as
a slight pull on the blind toward the lock to close it or a slight push to open it will cause the blind to lock itself into place.
My invention will be more clearly understood by reference to the accompanying specification and drawing, wherein- Figure 1 represents a perspective View of a blind and the manner of attaching the improved lock' of my invention to said blind; also the window-sill in which is driven a v hook for engagement with the lock when the blind is closed; Fig. 2 is a view of a portion of a wall in which is anchored a second hook for engagement with the lock on the blind when the latter is open; Fig. 3 is a Fig. 4 is a top plan view of the lock with the cover in place; Fig. 5' is a side elevation of.
the lock; Fig. 6 is a transverse sectionaleleva-tion, and Fig. 7- a top plan view of the lock showing the manner in which the operating spring is compressed when the parts are'moved by the hook for locking engagement or by hand for opening the lock.
"Referringmore specifically to Fig. 1, 1 represents the blind tobe fastened, 2 the window-sill, 3 the sill hook and 4 my inproved lock secured to the under side of the blind rat the end thereof farthest from the hinged end. In Fig. 2 the wall hook is represented at 5. In the subsequent figures the lock box or casing 6 may be cast or die formed, as is true of other of the assembled parts of my improved locking machanism, but the method of manufacturing these parts is immaterial so far as the working of my invention is concerned. 7 7 represent flanges on the cover 6 in which are suitable screw-holes 8, 8 registering with corresponding holes 9, 9 in the box4 for fastening the cover 6" thereto when the parts are assembled. The screws themselves are not shown. 7
InFig. 3, 10 represents a m'ember which terial having the lugs or projections 11, 11.
'These lugs 11 are normally opposite the opening 12, 13in the box 4 into which openings are inserted the hooks 3 and 5 respec tively, the particular hook which is inserted depending on whether the blind is to be fastened to the sill or to the wall. As shown in Fig. 8, it may be assumed for the purpose of illustration, that the hook 3 is the sill hook, shown in full lines, and that the hook 5, shown in dotted lines, is the wall hook.
I It will be obvious from the construction,
in either direction in the opening 18 in the side of the box 4.
The operation of my invention is as follows: Where it is desired to close the blind 1 by fastening it to the sill 2, the blind is either pulled or pushed in with suflicient force to cause the hook 3 to tion' of the spring and the lugll engages o enter the opening '12 in" the box" on the j blind. This causes the hk3 to move the member from the dotted line position, Fig. 7 to the full lineposition in the same figure, compressing the spring 16 until the hook 3 haspassed the lug 11 of the member 10, whenthe member 10-returns bythe acunder the corresponding lug on the hook 3, thus securing the hook 3 in th'e1lock,"and
' consequently locking the blind to the sill;
The same action occurs with reference to the hook- 5; when it .is desired to-lock' the U blindto the all of the building,,only in this case the Wall--hook5 enters the look in the'opening-13, that-is, in the sideof the lock oppositeto the opening 12. Whenit' is desired to open the lock to unfasten the blind from either the sill or the-wall, it is only necessary to move; the knob 17 against the spring. in a direction opposite from the particular hook engaged,'when, with a slight pull on the blind in the proper direction,
the hook Will be Withdrawn from the opening in the lockzand thenblind will be unfastened. l
. In accordance Withthe "pro isions of the patent statutes, I have herein shown and understood that I do not Wish to limit m'y-,
self to such specific form only, but wish 'to cover "the appended all I I tions thereof spirit and scope of "my invention. p i 7 What lcla mias new and deslre tosecure byLetters Patent of the/United Statesis:
1.,Ab1ind or shutter'lockcomprising a f metal box, a fsprin'g-pressedsliding latch having a detent on. opposite sides at the ends, said detents being adjacent respecv tively to openingson opposite sides and'ends' of thezbox and adapted toengage a catch the latch.
v 2. A'bli'nd or shat'enak com fism a metal box, -a sliding spring actuated latch 53 havinga. detent at each end given a normal elastic seat for movement in eitherjdirection 55 1 by a stud engaginggtwo springs anc'horedp f against abutments in the box, the box haV- ing openings to admit a catch onthe Wall o or sill 'when op'en or closed, and a knob securedto the latch projecting through a, slot 5 x in the'boX torperr'nit opening or closingthe 3 blind.
