Specification of Letters Patent.
Patented Nov. 30, 1920.
Application filed January 24, 1920. Serial No. 353,731.
To all whom it may concern: 7
Be it known that I, HORACE EDWARD MOR- TON, a subject of the King of Great Britain and Ireland, residing at Sydney, in the State of New South Wales, Commonwealth of Australia, have invented certain new and useful Improvements in and Relating to VVindow-Blinds, of which the following is a specification.
This invention relates to improvements in the type of window blinds known as Venetian blinds and the object of the invention is to dispense with the webbing which forms the ladder support for the laths.
A further object of the invention is to provide that any or all of the laths can be readily removed without interfering with the running gear. Another object is to increase the life of the blind. The invention consists of a trellis closing ladder formed of metal strips riveted together and arranged beyond-the ends of the window slats and between them and the window casing and to brackets or cradles on which the ends of the laths are supported.
Each alternate member of the trellis closing ladder is provided with a projecting stop piece which holds the members out of vertical alinement and insures that they will always open outward when the blind is drawn up.
The cradles which may be made of any suitable light sheet metal are L shaped, the horizontal member forming the support for the laths while the verticalmember is pivotally attached to the trellis members. The horizontal members of the cradle have spring clips into which the ends of the laths are sprung and are prov1ded with slots through which. the cord passes to work the blind.
When constructing blinds of over four feet in width it is advisable that the laths should be out in sections and supported by intermediate cradles which are made double with the trellis working between the vertical members. 0
At the top of the trellis ladders is the ordinary balance lath which governs the shading of the blind. r
The trellis ladders are supported to the pulley head by means of a pivoted rod or metal strip so that free movement of the laths is provided'each way to shade the light.
But in order that the invention may be -in Fig. 6 and separately in Fig.
Fig. 2 is a similar view showing laths in l the horizontal or unshaded position.
Fig. 3 is a front view of Fig. 2.
Fig. 4 is an enlarged perspective showing the construction of the trellis members.
Fig. 5 is blank from which one of the trellis members is constructed.
Fig. 6 is aview of supporting cradle.
Fig. 7 is covering plate for supporting cradle.
Figs. 8 and 9 show two views of the metal cap which is fitted on the ends of each lath.
Fig. 10 is a perspective view ofa double supporting cradle showing two of the trellis members attached thereto.
Fig. 11 is a plan of pulley head for blind with undivided laths.
together and to intermediate supporting brackets or cradles.
Between each supporting cradle there are four trellis members two upper 12 and two lower 13 which are riveted together at 14 and to the cradles at 15.
The construction of the trellis members 12 and 13 is shown clearly in Figs. 4 and 5. Fig. 5 shows the metal blank which is folded longitudinally to form the member 12.
The member 13 which consists of a metal strip is riveted between the folded sides of the member 12 and has a projecting shoulder 16 which bears against the back of member 12 and prevents the members hanging in vertical alinement and insures that the trellis will expand outward from the center between each cradle as the blind is pulled up.
The supporting cradle which is illustrated in Fig. 6 consists of a sheet metal plate 17 with the end portions of one edge curved inward to form spring clips 18 and the central portion bent upward at right angles to form a vertical member 19 to which the trellis members 12 and 13 are riveted. The trellis members 12 and 13 are also riveted to the cover plate 20 which is shown in osi tli on he cover plate 20 is provided for the purpose of covering the trellis members when the blind is up, these cover pieces are not shown in Figs. land 2.
On both ends of each lath 6 is a sheet metal cap 21 with central recess 22 on each side of which is a bead 23. The caps 21 taper toward the beads 23 and are provided with side flanges 24, which fit over the cover plates 20 on cradle 17. The caps 21 on ends of the laths 6 are supported on the brackets or cradles 17 the beads 23 being sprung under the spring clips 18. The recesses 22 in caps 21 overlie the apertures 25 in cradles l7 and provide a through passage for the cords 26 which work the blinds.
The top of the trellis ladder is secured to the ordinary balance lath 27 to which are attached the cords 28 by means of which the blind is shaded.
The balance lath 27 is secured to the pulley head 29 by rods or metal strips 30.v
The blind is operated in the ordinary Way by cords passing down from the pulley head.
When the blind is over say four feet wide the laths are divided and have their inner ends supported on double cradles which are affixed to an intermediate trellis ladder as illustrated in Fig. 10' in this case an extra operating cord passes through the center of the pulley head.
I claim.
1. An improved window blind comprising a plurality of closing metal trellis members supported from a pulley head and arranged beyond the ends ofeach of the blind slats and between them and the window casing, bracket members to which one end of each of said trellis members are pivotally connected and spring clips formed by said bracket members into which the ends of said window slats are detachably clipped.
2. An improved window blind comprising slats or lathshaving on their ends metal caps adapted to engage spring clips on supporting brackets attached to metal trellis closing ladders suspended from a fixed pulley head and adapted to be operated by cords or the like passing therethrough substantially as and for the purpose herein set out.
3. An improved window blind comprising a plurality of closing metal trellis members supported from a pulley head and arranged beyond the ends of each of the blind slats and between them and the window casing, bracket members to which one end of each of said trellis members are pivotally connected, spring clips formed by said bracket members into which the ends of said window slats are detachably clipped, and cover plates adapted to be placed outside the said brackets and the attached ends of said trellis members.
In testimony whereof I have affixed my signature in presence of two witnesses.
