(Cl. 156-17 ) My invention pertains particularly to a folding bars of each of the pantographs. Both guide pieces 21 and 28 are rigidly attached to pipe 26. metal shade which is to be attached to the out side of dwellings or other habitable quarters to The guide pieces 21 and 28 are formed from strap prevent the sun’s rays entering such quarters iron, bent in a U shape, the sides of the U in each case being pierced by holes through which 5 through windows. guide pipes 9 and 8 respectively are disposed. An object of my invention is to provide a win dow shade which will serve as a storm blind as well as a sun shade, which will be sufficiently weather resistant to permit its use throughout all of the seasons of the year, and which, when not in use, may be folded into a non-obstruc tive, neat appearing bundle. Other objects of ‘ my new invention will be made apparent in the following speci?cation. My invention will be understood from the fol lowing description, taken in connection with the accompanying drawings in which: Figure 1 illustrates in side elevation the com plete shade properly disposed with respect to a 20 window in a wall of a building. Figure 2 illustrates the complete shade in front elevation. . Figure 3 illustrates a cross-section of the shade taken along the plane 3-3 of Figure 2. Figure 4 illustrates a cross-section taken along the plane 4-4 of Figure 1, showing the detail ‘of the manner in which the lattice bars and the shades are attached together with bolts. Figure 5 illustrates a cross-section along the plane 5-—5 of Figure 2, and shows a plan view of guide piece 28. Figure 6 illustrates a cross-section taken along the plane 6-45 of Figure 2 and shows a plan view of guide piece 21} Referring to the drawings, a metal frame work, which is made up of guide pipes 8 and 9, a pipe l0 and pipe nipples ll, l2, l3 and Ill and T’s l5, l6, ll, I8 and I9, is attached to the wall 2!! of a building by means of lag screws 2|. Metal Washers 22 are disposed between nipples l3, l4 and the wall. Two pantographs 23 and 24 are formed by metal lattice bars and bolts. These pantographs are maintained in position with re spect to each other by metal shades 25, which 45 are each attached at their longitudinal extremi ties to one lattice bar in each of the pantographs. A shade is attached to ‘each of the lattice bars, which slopes downward and away from the wall, while no shades are attached to the last bars which slope upward and away from the wall. Both pantographs are suspended from pipe Hi, the upper lattice bar of each pantograph being pierced by a hole through which pipe ll] extends. A pipe 26, to the extremities of which are attached 55 guide pieces 21 and 28, pierce one of the lattice Pulleys 29 and 3| are attached to guide pieces 28 and 21 respectively. A cord 30 is attached to the T l6 and leads thence through pulley 29, thence through pulley 3|, and thence upward and 10 through a pulley 32 to a lug in any convenient location to which the extremity of this cord may be attached. As illustrated in Figure 4 the lattice bars I) to which no shades are attached, are pierced by a smooth hole through which bolts 33 are loosely 15 ?tted. The bolts 33 are threaded through lattice bars a and pierce the flanged edge of shades 25, this ?anged edge being held in place against lat tice bar a by means of the nuts threaded on bolts 20 33. ‘ The guide piece 28 is equipped with slotted holes through which the guide pipe 8 is disposed, which permits longitudinal movement of pipe 26 with respect to guide pipe 8, while the guide piece 21 is equipped with around hole through which guide pipe 9 is disposed and in which guide pipe 9 ?ts - neatly. ' By means of pulling on the extremity of cord , 3B, the pantographs, together with the shades, 30 may be raised to any desired position, limited by a position in a compact bundle at the top of the window, in which position they may be held by means of attaching the cord to the lug. Re leasing the cord will permit the pantographs, to 35 gether with the shades, to descend by reason of their own weight, to any desired position. While I have described in detail one form in which my new invention may be incorporated, it is understood that I do not intend to limit myself 4.0 to these details, rather intend to claim broadly all of the advantages which are inherent in my new invention. I claim: 1,. A window shade comprising a pair of spaced 45 vertical guide rods, a pair of laterally spaced lazy tong members pivotally mounted at their upper ends and adapted for vertical extension and re traction between said guide rods, shade members extending across and secured to said lazy-tongs, 50 oppositely disposed yokes secured to said lazy tongs at a point below said pivotal means and slidably engaging the respective guide rods, .pul leys carried by said yokes, and an operating cord secured at one end at a ?xed point adjacent the 55 2 2,123,128 upper ends of said lazy-tongs and running over said pulleys, for adjusting the position of said lazy-tongs. 2. In a window shade comprising a pair of lat erally spaced lazy-tongs adapted for vertical ex tension and retraction adjacent a Window, shade members extending across said lazy-tongs and terminating in right angular projections at their opposite ends, said angular projections being se 10 cured by the pivotal connections of adjacent lat tice bars of the respective lazy-tongs. 3. In a Window shade of the type comprising a pair of spaced lazy-tongs adapted for extension and retraction adjacent a Window and having shade members extending across said lazy-tongs, means for pivotally connecting adjacent lattice bars of said lazy-tongs and for attaching said shade members, consisting of bolts extending through adjacent lattice bars, the shank of each bolt having a plain portion for freely engaging one lattice bar, and a threaded end for engaging complementary threads in the other lattice bar, said threaded end projecting beyond said last named lattice bar, and means at opposite ends of said shade members embracing the threaded ends of said bolts for securing the respective shade members in place on said lazy-tongs.
