PORTABLE DOOR AND WINDCVV FASTENER.
Specification of Letters Patent. Patented Sept. 21, 1220.
Application filed March 5, 1919. Serial No. 280,842.
To all whom it may concern:
Be it known that I, CHRISTIAN P. ScHoEL- KOPF, of St. Paul, Minnesota, have invented a new and useful Improvement in Portable same, reference being had to the accompanying drawings, forming part of this' specification.
My invention has for its object to provide a simple and eflicient door and window fastener that is portable, capable of being readily detached from the door or window and to be carried in the pocket, so that it is adapted for use, for-example, by tourists or travelers. V
Generally stated, the invention consists of the novel devices and combinations of parts hereinafter described and defined in the claims.
The improved fastener is illustrated in the accompanying drawings wherein like characters indicate like parts throughout the several views.
Referring to the drawings:
Figure *1 is a side elevation of the fastener;
Fig. 2 is a bottom plan view thereof;
Fig. 3 is a fragmentary perspective show ing the fastener applied to secure a door; and
Fig. 4 is a fragmentary perspective showing the fastener applied to secure a window.
In Fig. 3, the numeral 5 indicates a door, the numeral 6 the door casing, the numeral 7 the floor. In Fig. 4c, the numeral 8 indicates a lower sash of the window and the numeral 9 indicates the window frame.
The fastener is made up of three main ele- V ments, to wit: a channel-shaped arm or link 10, a forked arm or link 11 and a head 12.
The forked arm 11 is provided with a forked free end 11% and its other end is pivotally connected by a rivet 13 to the intermediate portion of the sides of the channel-shaped arm 10. The head 12 is provided with a frictional facing shown as formed by a knurled or serrated surface 14:. Said head 12 is provided on its back with a lug 15 that projects between the flanges of the arms 10 at one end thereof and is pivotallyconnected thereto by a rivet 16. The extended, end of the channel-shaped arm 10,'it will be noted, affords a stop that engages the back edge of the arms 11 and thus limitsthe buckling action of the toggle made up of the arms 10 and 11, to a position in which the axis of the pivot 13 is slightly below a dead center or line of strain represented by an imaginary line drawn from the pivot 16 to the points of the pronged head 11.
The manner of. applying the device to secure a door in a closed position is illustrated in Fig. Forthus applying the fastener, the points of the pronged end 11 are placed on the floor and the frictional face 1 10f the head 12 is placed against the door, while the toggle members 10 and 11 are buckled upward, and then the toggle is pressed downward to its position past its dead centerandthere locked, and will then.
hold the door tightly closed. Any force applied to the door tending. to open thesame, will, of course, be resisted by the fastener. The extended end of the member 10, when the toggle is buckled affords a projection adapted to be engaged by the foot to force Y the fastener against the door under very considerable pressure. g
In applying the fastener to the window, as shown in Fig. 4, the prongs are preferably engaged with the groove in the window frame and the head 12 applied to the upper edge of the sash 8. The device is of extremely simple construction and small'cost and, in practice, has been found highly efii cient for the purposes had in View.
What I claim is:
bination with a channel-shaped arm provided at one end with a oivoted head having a frictional face, of a-second arm hav ing a pointed outer end and having an inner end that works between-and is pivotally connected to the intermediate portions of the flanges of said first noted arm.
2. In a door or window fastener, the combination with a "channel-shaped arm, of a 1. In a door or window fastener, the com- 7 head having a serrated face and with a lug on itsback, which lug is pivotally connected to the ends of the flanges of said channelthe extended portion of said ohannel shapei shaped arm, and an arm having a pi'onged arm affording a stop for-limiting the buck- 10 and polnted outer end, the other end thereling action of the members in one direction.
of Workin between the flanges of said chana q 7 -w nel-vshaapecf arm and pivo t'ally connected SQHDELLOL thereto by a rivet, the pivotal connection Witnesses:
between said two arms being movable from AMELIA SoHonLKoPF,
one side to the other of a dead center, and IRENE SoHoELKoPF.
