BURGLAR-PROOF BOLT ATTACHMENT.
Application filed April 10, 1918.
To all whom it may concern:
Be it known that I, JOHN L. Corrine, a citizen of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in Burglar-Proof Bolt Attachment-s, of which the following is a specification.
This invention relates to builders hardware, and more especially to bolts; and the object of the same is to apply to a bolt, particularly to one which is employed on window blinds and the like, an attachment which will prevent. it from being retracted by an unauthorized person inserting something between the slats of the blind.
In many cases the blinds are double and meet at; the transverse center of the window. In other cases one large blind covers the entire window, or it may be a slatted door which closes the door opening. In any event, the blind or blinds are often lockedin closed position by means of" a bolt on the inside. If this bolt is already 'in place my attachment may be employed across its near end. But I prefer to'manufacture the bolt and the attachment at one time, and have so described it in the following specification and illustrated it in the drawings, wherein Figure 1 is an elevation of this improved bolt and its attachment,
Fig. 2 is a. horizontal section on the line 22 thereof,
Figs. 3 and 4 are vertical sections on the lines 33 and 44 of Fig. 1.
While the members shown might be two blinds, let us assume that B is the blind closing into the frame F. A keeper 1 is secured to the inside of the frame. A base plate 2 is secured to the inside of the blind and has loops 3 upon it in which slides the bolt 4:, being moved in either direction by an appropriate handle 5. As shown in Figs. 1 and 2 when moved to the left its tip enters the keeper 1 and locks the element B within the element F and when moved to the right the bolt is unlocked.
Across what We will call the inner end of the bolt I mount the attachment forming the subject matter of the present invention.
Here ,the numeral 10 designates a plate which may be separate from the base plate 2 or formed as a part thereof, according to whether this attachment is applied to a bolt already in place or is made as the bolt Specification of Letters Patent.
Patented July 16, 1918.
Serial No. 227,736.
is made. At its upper edge this plate is turned inward at right angles in a guard 11 projecting inward for some distance and overlying the inner end of the boltand the parts yet to be described. Upstruck from ward the plate end and hold it there.
When this attachment is applied as shown, the bolt 4: cannot be retracted until the latch is first raised or moved outward from its base plate 10, and this can only be done by inserting the nail or finger behind the thumb piece 15 and pulling it forward against the tension of the spring 16. As soon as the inner end of the bolt 4 passes under the latch, the latter may be released and the bolt slides along behind it. Now
when the bolt is again projected to throw its tip into the keeper 1 its rcarend slides out from under the latch and the latter snaps against the'plate lOunder the tension of the spring 16. The important feature of my invention, however, is the guard plate 11 overlying this latch and in fact overlying and protecting everything at the inner end of the bolt; and therefore an unauthorized person can hardly insert a bent wire or the like through the slats of the blind B and slide the bolt backward, because the bolt is latched in its locked position in a manner which will be obvious. This is on the assumption that this bolt is applied to the lower cross bar of the blinds. Even if we assume that it is applied to the midrail of a slatted door and that someone might reach upward through the slats in a lower panel, the wire could hardly be manipulated so as to be passed under the latch and raise the same, and at the same time another wire introduced and borne against the handle 5 to retract the bolt. Therefore this device practically locks the bolt in closed position against the manipulation of an unauthorized person from the outside.
The foregoing description and the drawmaterials, dimensions, et cetera, as may prove expedient and fall within the scope of the appended claims.
Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent,is:
V1. The herein described boltlock com prising a base plate disposed at the rear end ,.provided with a thumb-piece,
of the bolt and having upstruck ears, its. upper edge being bent at right angles into a guardoverhanging the bolt and the ears,
,a pinpivotally mounted through said ears and carrying at one end an upstanding latch."
and a spring ,coiled' on the pin between the ears and throwing said latch normally toward the base plate. V 2. In abolt the-combination with a keeper, the base plate for slatted doors and the like,
' for the door having an enlarged rear end whose upper edge is bent inward at rightanglesto its bottom, guides on thls plate, and a bolt 'slidably mounted through said}.
} guides; of a latch hinged at its lower end '1 to said base plate'at a point to pass therearv f end of the bolt when the latter is projected,
its upper end at this time standing beneath said guard, and a spring bearing said upperf end normally agalnst the enlarged portion of the base plate, for the purpose set forth.
'i mounted on one member, a base plate adapted to be mounted on another member, its} copies of this patent may be obtained for 8. In a device of the class described, the e l V combination with a keeper adapted, to be .springtur'ning said pinnormally in a direction :to'press the free end of the latch against the base-plate, for the purpose set forth.;.'
.s 4. In a device classdescribed, the
Ycombinationfwit'h askeeper adapted to be mounted on one member,anda horizontally sliding boltfadapted'to be mounted on another member; of a baseplate attached to saidleist-nam'ed member at the rear end of thebolt, a latch pivoted at its lower end to said plate; on a, linepa'rallel with the length of said bolt,;yielding means pressing it normally againstfsaid platein rear when the latter is rojected, and a fixed guard on the base plate overlying the latch. Intestimony whereof I aflixrmy signature .in presence of 'two witnesses.
