DEVICE FOR OPERATINGWINDOW-SHADES.
SPECIFICATION forming part of Letters Patent No. 301,554, dated July 8, 1884. Application filed May i2, 1884. (No model.)
To all wiwm/ it may concerti.:
Be it known that we, VALENTINE BLANK andTHoMAs J. ANTHONY, both citizens ofthe United States, residing at Springfield, in the county of Clark and State of Ohio,have jointly invented certain new and useful Improvements in Devices for Operating VVindoW-Shades; and we do declare the following to be a full, clear, and exact description of the invention, such as will ena-ble others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and gures of reference marked thereon, which forni a part of this specification.
Our invention relates to devices for operating window-shades, and is an improvement upon the device used for the same purpose for which Letters Patent No. 295,901, dated April l, 1884, were granted to Valentine Blank and Thomas J. Anthony. In that device an inverted- L-shaped inetalbar extends across the window and down one sideof the same, which barcarries the shaderoller, and has pinions attached at the ends of the latter,which engage with the teeth oi vertical toothed racks on either side of the Window. In this yimprovement we dispense with the pinions and the toothed rack-bars in order to render the device noiscless, to simplify the construction, and lessen the cost of construction. The guideway through which the vertical limb of the L-shaped metal bar (which carries the shade) extends and operates is also simplified, and the springcatch of the same made to operate 5ok allow it to operate freely on the rods b, an open keeper, having a vertical L.- shaped slot therein to allow itto slide ovcrlcgs b2, is
without a dog, and is more certain and posi I used to iuclose the rod Z1 on the right side, Fig. l. On this is placed the small angular bracket-plate b, in which the right end ofthe roller is pivoted. On this bracket-plate the metal bar C is placed, and the Whole secured together by a bolt, h, the upturned lugs 'i2 of the keeper b" preventing any lateral Inovement of the latter on the bar, as seen in the detail, Fig. 6, which shows a top view of bar C as attached, also a separate view ofthe bracket-plate.
The end of bar C, which is turned downwardly at right angles, as seen on the left in Fig. l, has attached thereto the bracket d, in which this end of the shade-roller o is pivoted, an d under this,with two guide-rollers, one pivoted' in each end-is a flat case, (c This latter consists of two plates, a3 and c4, the former of which has its edges turned inwardly at right angles, while at is a plain lia-t plate, lugs or edges i" resting thereon, so as to form an opening between the two plates for the horizontal rollers c', as well :is/for' the rod b. 'Iliecase is cut away at each end on the outside edge, so as to' leave the inclosed part about onethird the length of the case, thro ugh vwhich rod b extends. The case is oblong, and a roller is pivoted in each end, so as to have a bearing on the inner edge of rod b above and below the .axial line of the shade-roller. The bracket-plate CZ is intermediate between bar G and the oase c, and a single bolt secures the three pieces together, similar to the fastening n the opposite side of the Window. Theend of bar C lies between lugs a" ai and the proj ecting or bearing part of the plate d,'in which the roller c is pivoted, (at the left end, Fig. 1,) and lateral movement of the parts thereby prevented. The rollers a; being upon either side of the plane of the bracket-fastenings, tendV to keep the bar C and its attached shaderoller in a horizontal vplane while being oper ated, and prevent binding between either of power is applied to the vertical limb of '0, a simple slide-plate or keeper, 0*, can be used on that side. Being in the same vertical plane above the point g', it is easily moved either up 4or down; but without the aid of rollers at the end of the horizont-al arm of the bar G on the opposite side of the window to ease the movebracket and keeper, with a cross-section of the rods Z2 and the sliding members. y As the IOG 2' sores/1' be liable to bind at this end. The case a and keeper I)AL arel slipped onto bars b at the top ends, while a hook, j', at the lower ends of the latter prevents danger of the device slipping off in case of disengagement of the spring e, or the breaking of the same by accident.
The guideway D consists of a singleplate of oblong shape, having an elevated middle part and depressed ends c', with openings c between the two parts for the operation of the 4bar C therein. It is provided with feet on each side at the ends, by which itis attached to the casing of the window, and has a fiat curved spring, @,with its lower end fastened to the foot ci. This spring extends upward under the middle part, and has anotch, i/,which engages with notches M in the edge of bar C. By reference to Figs. 4 and 5 the construction of the guideway and its spring e can b'e seen. In the edge View,` Fig. 4, -the engagement of spring e with the notch z in the bar can be noticed. Above the right-angled notch i", cut in the same, its end is attached to the shank of the knob e. The top of the spring is cut half away to form the notch or shoulder i. The shank of the knob extends under the bar C across the guideway, and is operated by pressure upon k-nob e, (on the right side of thelatter,) which pushes the spring out of the notch. The spring operates automatically in its engagement with notches Mwhich latter are sloped in from below for that purpose) as the bar C descends in lowering the shade.
In Fig. 2 two views of the right-angled bracket-plate cl, used in connection with the end of the bar C at theleft end of shade-roller c in Fig. 1,are shown. It will be noticed that this plateis reversible, and can be used on either side of the window, lugs d2 on either side ofthe opening d3 allowing it to be changed to either end of the shade-roller. Both this plate and b3 are provided with long holes d to permit of their adjustment.
The shade is operated,in changing the locament of the bar upward on the rod-), it would tionof its rol1er,by the movement of bar C up or down, as in the device referred to in our former patent, said bar being similar in its construction. v
vWe claim as our inventionl. In a device for operating window-shades, the combination of the L- shaped. bar, the shade-roller pivoted thereon, a sliding keeper at one end of said shade-roller, and a pair of pivoted rollers at the opposite end, both attached to said L-shaped bar, and the smooth vertical rods each side of the window, on which said rollers and keeper operate, substantially as set forth.
2. In a device for operating window-shades of the class described, the combination, with the vertical rods, the inverted-L-shaped bar, with keeper and roller devices thereon, upon either side of the window, adapted to slide upon said rods, of the guideway formed of a single plate with openings therein, and having the iiat bent spring with knob attachment, as set forth.
3. The combination, with the end of bar C and the rod b on the same side of the window, of the roller-case a, having the vertically-pivoted rollers a vtherein adapted to engage said rod on the edge of the same when operated, as set forth.
4f In a device for operating window-shades of the class described, the combination, with Y the L-shaped bar having notches therein, the
vertical rods, the case provided with rollers,
and the keeper operating thereon, the angular bracket-plates, andthe pivoted shade-roller, of the guideway,with its spring and knob attachment, constructed and operated as specified.
In testimony whereofwe afix our signatures in presence of two witnesses.
