i IMPRCWBD TENOIIFOR BLIND-SLTS.
IO ALL WHOM IT MAY GONGERN: y 4
De it'knoivn thatl, WILLIAM McFARLAND, of New York, No..519 West Twenty-Fourth street, in the county and State of New York, have invented a new and improved Tenon for Blind-slats 'apdI do hereby declare that the following is a full, clear, and exact description thereof, which will lenable those skilled in theart to make and use the same, reference being had to thc accompanying drawing, forming part of this speeiicatiom'irx which drawingi K 5 i Figure 1 represents a blind-slot, one ofovhose ends is provided with one of my improved tenons.
Figure 2 is a central longitudinal section. i
The object of this-invention is to provide tenons for blind-slats, when the original tenonsare broken off or injured so as to become inoperative. Y Heretofore the breaking-off or the decay of a tenen has caused the' entire loss ofthe-Slat, there being` no means or device known, previous to my invention, whereby the tenen could be restored or repaired without incurring too much expense. And, furthermore, the repair or restoration of a broken tenori is diiicult without the removal of one of the side-bars ofthe frame.y
My invention obviatcs the diiculties of repairing thetenons of slats, and reduces the expense to a small amount, so that iti-becomes cheaper 'to use my improved tenen than to renew the slat. Among other advantages I may also mention this one, that, by enabling ono to retain the old slat, a uniformity in the color or shade of the slats ofthe blind is'preserved throughout. l i
The letter designates a slat,`on, o of Whose original tenons has been broken ofi' orbecome inoperative, while the other original tenori, B, isstill sound. The lette-r C designates my improved tenen, which has been applied and fitted tothe sla't in such a manner as to take the place ofthe one removed. My improved tenen C is made of metal, by lcasting or by any other convenient process, or it canbe made of any other suitable mate.4
rial. I have found that theyv can be made advantageously ofcast metal, and I have therefore shown one oi' that kind in this example.v ff .fp
l The tenon has onits inner end anescutcheomplate, D, which is-provided with screw-holes, to enable it to be permanently secured to the facev of ith-e slat, theinner facebeing selected for that purpose. Tho connection et' the escutcheon-plate to the tenfou proper is by a bevelled shoulder, E, Whose sides are made square, and the said shoulder is fitted in a recess of correspondingshape, which I cut in the end of the slat,`at the'plaee oecuf pied by the original tenon. In this example, the plate D is placed on the slut Without. being let in, so as to be flush with its surface, and in order to bring the tenen proper, C, at its proper place in the end' of the slat, the plate D is slightly raised above-the tenen, as is seen at the point F, but their adjacent surfaces will be in the same plane, or nearly so, in those cases where the plate is to be let in', so as to bring its surface ush with the face of the Slat. l v
It will be observed that this invention preserves the rest of-the slat unimpaired, and provides a new tenen of great strength. Any householder can apply my' improved tenen to a broken 0r injured slat, and that, too, wit-hout drawing the staple that hinges it to its stile, by cutting in tho end ofy the slat. a recess of the proper shape to receive they shoulder E, and then inserting one of my improved tenons in the proper mortise of the frame, andfitting the eseutcheon-plate D to the slat, and fastening it in a secure manner. The shoulder E- and plate D combine to keep the tenen in its proper position, and resist every tendency to displaeement'or working loose.- i v A. What I claim as new, and desire to secure by Letters Patent, is'- The tenen G, constructed with a bevelled shoulder, E, and fastening-plate D, substantially as and for the purposes set forth.
This specification signed by me, this seventeenth day of December, 1867. v
WILLIAM McFARLND.
