CORD ATTACHMENT FOR WINDOW-SHADES.
Specification of Letters Patent.
Patented Nov. 5, 1907.
Application filed June '7, 1907- Serial No. 377683.
To all whom it may concern:
Be it known that I, EDMUND F. HARTSHORN, a citizen of the United States, residing in Newark, county of Essex, and State of New Jersey, have invented a certain new and useful Improvement in Cord Attachments for Window-Shades, of which the following is a specification.
The object I have in view is to produce means for attaching the cord to the slats of window shades and the like which will be cheap in construction; can be easily applied or removed without the use of special tools; will conceal the knot of the cord; will give the security of fastening afforded by a clasp or clip fastener as distinguished from a screw eye, and can be attached to shades having a depending fringe without interfering with the fringe.
In the accompanying drawing, which shows the device on an exaggerated scale, Figure l is a cross section through the slat of a window shade and the cord attachment applied thereto, and Fig. 2 is a perspective View of the cord attachment.
The cord attachment is made of a single piece of plate metal having a body 3 of elongated form, at the upper end of which is an inwardly turned tooth or prong 4. The lower end of the body 3 is bent upwardly to form a trough 5 for holding the knot of the cord which trough is of less width than the bottom of the shade slat. The upwardly turned end terminates in shoulders 6, 7 which bear against the bottom of the slat, and an upwardly projecting prong or tooth 8, which enters the bottom of the slat. The front of this upwardly turned side is provided with a slot 9, open at its upper end, through which the knotted end of the cord is slipped, the slot not being large enough to permit the knot to pull through The seeming of the cord attachment to the window shade is illustrated in Fig. l. The prong or tooth 8 enters the bottom edge of the slat 10, while the prong or tooth 4 enters the side of the slat. The device can be applied by making a hole with an awl for the reception of the prong 8 and by driving the prong 4 into the side of the slat with a hammer. The shoulders 6, 7 limit the extent to which the prong 8 can enter the slat, leaving the trough 5 depending from the bottom of the slat and giving room for the knot 11 of the cord 12. By making the clasp or clip so that it does not embrace the entire slat at the bottom, but is secured thereto by a prong entering the bottom of the slat, the attachment does not interfere with the fringe 13 when the shade is provided with such a fringe.
What claim is:
1. A cord attachment for window shades which comprises a clasp formed of a plate having a prong adapted to engage one side of the slat, and an upwardly turned lower end having a prong adapted to engage the bottom of the slat, substantially as set forth.
2. A cord attachment for window shades which comprises a clasp formed of a plate having :1 prong adapted to engage one side of the slat, an upwardly turned lower end having a prong adapted to engage the bottom of the slat, and depending below the slat to form a trough for the knot of the cord, substantially as set forth 3. A cord attachment for window shades comprising a clasp formed of a plate having a prong adapted to engage one side of the slat, an upwardly turned lower end having a prong adapted to engage the bottom of the slat, a trough for the knot of the cord depending below the slat and a slot in the side of the upwardly turned end open at its top and adapted to receive the cord, substantially as set forth.
4. A cord attachment for window shades comprising a clasp formed of a plate having a prong adapted to engage one side of the slat, an upwardly turned lower end having a prong adapted to engage the bottom of the slat, shoulders on the upwardly turned end limiting the entrance of the prong into the bottom of the slat, a knot trough depending below the slat,-and a slot in the side of the upwardly turned end to receive the cord, substantially as set forth.
5. A cord attachment for window shades comprising a plate 3, prong a, trough 5, shoulders 6, 7, prong 8, and slot 9, substantially as described for the purposes specified.
This specification signed and witnessed this fifth day of June, 1907.
