STEPHEN PALMER, OF LANSINGBURG, NEW YORK.
WINDOW-BLIN D.
SPECIFICATION forming part of Letters Patent No. 343,724, dated June 15, 1886.
Application filed March 5, 1886 Serial No. 194,104. (No model.)
To aZZ whom it may concern:
Be it known that I, STEPHEN PALMER. a resident of Lansingburg, in the county of Rensselaer and State ofNew York,have invented certain new and useful Improvementsin \Vindow- Blinds; and I do hereby declare that the following is a full, clear, and exact description of the invention, that will enable others skilled in the art to which it appertains to make and use the same, reterence being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.
Similar letters refer to similar parts in the several figures therein.
My invention relates to improvements in window-blinds having adjustable slats, and the objects of the invention are fully stated in connection with the following description.
My invention consists of the novel construction and combination of parts described in the specification, and pointed out in the claims.
Figure '1 of the drawings is a front elevation of a Window-blind with a portion of one stile broken away to show a slat-dowel seated in its socket. Fig. 2 is a central vertical section of a portion of one of the stiles, showing the dowel-seat. Fig. 3 is a side view of one end of aslat, showing one form ofslat-dowel. Fig. 4 is a plan view of a dowel-socket and a portion of one of the stiles. Fig. 5' is an end view of slat shown in Fig. 3. Figs. 6, 7, and 8 are' side views of one end of aslat, showing modified forms of slat-dowels. Fig. 9 isa sectional view showing a slat-dowel seated in its socket in the stile.
My present inventionis an improvement upon the invention described and claimed in my application for Letters Patent filed in the United States Patent Office December 31, 1885, No. 187,265, for improvements in Window- Blind Slats, and my declarations therein contained in reference to the state of the art and objects to be attained will apply with equal force to my present invention.
The difficulties to be overcome are the varying degrees of friction between the ends of the slat-dowels and the stiles, caused by defective parallelism of the stiles, Wear in use,,accuxnulation of paint upon the ends of the dowels, and varying degrees of resistance afforded by different portions of the materials employed in construction.
The frames of window-blinds are composed of stiles S and rails R, secured together by mortise and tenon. The stiles are provided with sockets B, oppositely located at suitable intervals,and adapted to form seats for the slatdowels t, rotary therein, and serving as pivots for-the slats A, one on each end of each slat. The sockets B are customarily formed by a bit having a central feed screw, which makes the central aperture, 0, in the bottom of the'socket. This aperture is in the form of a hollow cone, and its walls are softened and torn by the withdrawal of the screw. The slat A is provided with a dowel, t, upon each end adapted to enter and looselyfit the socket B. The dowels are provided with projections a, centrally projecting from the ends of the dowels, and adapted to enter and be seated in the central apertures, G, and form pivots for the slats to turn upon.
The mortises and tenons of the stiles and rails are indicated by dotted lines in Fig. 1, and after the slat-dowels are inserted in their sockets the stiles are drawn tightly to place upon the rails, which forces the pivots a into the apertures O, as shown in Figs; 1 and 9, and the slats having been connected by adj ustingrod r, and the parts of the frame secured in place, the blind is wholly formed. As the pivot a, theprojecting end of which is ofabout the same diameter as the mouth of aperture G, enters the contracted portion of the aperture, the walls of the latter are forced into close contact with the pivot, and the impinging surfaces are rendered very firm and rigid by the compression, whereby a better bearing-surface is afforded for the pivot. The friction between the compressed parts is sufficient to prevent the slats from being rotated by the wind, to produce an unpleasant rattling noise, and wear out the parts, and the diameter of the pivot being very small the friction is easily overcome by the hand of the operator when it is desired to adjust or readjust the position of the slats through the adj usting-rod. The distancethat the pivots may be forced into the central apertures, O, can be varied considerablyhvithout materially changing the frictional resistance offered to their rotation. This is a very important feature, as the stiles, if parallel with each other in the ii rst instance, frequently change relatively and lose their parallelism.
In the forms of construction heretofore employed, if the stiles should warp and spring apart the dowels would be loose in their sockets and rattle, while if they happened to spring toward each other the ends of the dowels would come in contact with the stiles at surfaces upon their largest diameter, and the frictional resistance frequently became so great as to render it impossible to rotate them by means of the adjusting-rod 0', while in my improved device the variation of the stiles is rarely if ever suiiicient to withdraw the pivots from contact with their hearings in apertures C so that they can rattle, or force them so tightly into the apertures C that they cannot be readily operated by the adjusting-rod.
It might sometimes happen that the mate rial of which the stiles are made would vary in quality, the walls of aperture 0 yielding more freely in one stile than in the other, and I make use of the shoulder (Z, formed by the different diameters of the dowel tand pivot a upon one end of the slat, to force the pivot on the other end of the slat into the aperture having the less yielding walls, as the distance to which either pivot can enter its appropriate aperture is limited by contact of shoulder 01 with the bottom of socket B; but the resist ance to entrance of the pivot intoits aperture will never be so great at either end as to cause inconvenient or injurious friction between the socket-bottom and the shoulder d at the other end. The end of the dowel may be cut down to form the shoulder (1 upon a smaller diameter, 1), as shown in Figs. 7, 8, and 9, whereby still less frictional resistance between the shoulders and socket bottom will be offered to the operation of the adjusting-rod, and especially when paint enters the sockets and reaches the ends of the dowels.
In the forms of construction heretofore employed, when the dowels come in contact at the surfaces of their largest diameters, a little paint would soon cement the contact-surfaces together, and the leverage of resistance being considerable it became impossible to separate the parts and rotate the slats by the adjusting-rod; but my improved device not only reduces the diameter of the contact-surfaces, but removes them a considerable distance at all points from the side walls of the socket B, so that considerable paint Inightenter without reaching the eontactsurfaces.
As I employ the saws which form the ordidinary slat dowels to cut down the ordinary dowels to produce the projections c and b, I prefer to make the parts a, b, and t cylindrical in form; but they may be made in the forms oi" frustuins oi cones, as shown in Figs. 6 and 8.
\Vhat I claim as new, and desire to secure by Letters Patent. is-
1. Ablind-slat dowel on which are formed pivotal end projections, a b, dill'ering from each other and from the dowel t in diameter and separated from each other by a shoulder, d, sul'istai'itially as shown and described.
2. \Vindowblinds having slat-pivotsa,separated from the body tof the dowel by a shoulder, d, in combination with stiles having the socket 3, and central conical aperture, 0, substantially as shown and described.
In tcsti mony whereofl have hereunto set my hand this 2d day of March, 1886.
STEPHEN PALMER.
