FLEXIBLE TO THE LUGRIN FLEXIBLE DOOR SHUTTER.
SPECIFICATION forming part of Letters Patent No. 550,630, dated becember 3, 1895.
Application filed January 15, 1891. Serial No. 377,800. (No model.)
.T at whom it may concern:
Be it known that I, I-IoRATro' N. H. LUGBIN, a citizen of the United States, residing at \Vorcester, in the county of WVorcester and State of Massachusetts, have invented new and useful Improvement in Flexible Shutters, of which the following is a specification, reference being had to the accompanying drawings, in which- Figure 1 represents a portion of a flexible shutter embodying my invention. Fig. 2 is a sectional view on line an ac, Fig. 1; and Fig. 3 shows a similar sectional view of one of the parallel bars forming the body of the shutter,
r 5 and showing a slight modification in the method of constructing the hinge.-
Similar letters refer to similar parts in the several figures.
My invention relates to certain improvements in flexible shutters composed of a series of parallel bars or leaves hinged together at their edge; sand it consists in certain detail of construction, as hereinafter described, and set forth in the annexed claims.
Referring to the drawings, .A denotes the parallel bars or leaves of which the body of the shutter is composed, the bar upon the left side of Fig. 1 being shown asdetached from the shutter and a portion of the bars in Fig. 0 1 are shown in sectional view, in order to disclose more clearly the construction which forms the essential feature of my present invention. The bars or leaves A are preferably formed of wood and their length corresponds with the width of the shutter, the width. of the bars being determined by the uses to which the shutter is to be applied and the effect it is desired to produce. Ordinarily I make the bars from one and one-half to two and one-half inches in width and from onehalf inch to three-quarters of an inch in thickness, and upon opposite edges of each bar are the barrels B and 0, preferably formed integrally with the bar itself. The barrels B upon one edge of the bar are provided with pintles B, concentric with the barrels B, and the spaces intervening between the barrels B are made equal to the length of the barrels 0 upon the opposing edge of the adjacent bar. The ends of the barrels O are provided with mortises extending from the edge of the barrels toward the center of the bar a sufficient distance to allow the pintles B to be received and brought concentric with the barrels O.
In constructing the flexible shutter the ad jacent bars are hinged together by bringing their opposing edges together, carrying the pintles B" into the mortises O, and then inserting a small block 0 Fig. 2, in order to close up the open end of the mortise G and prevent the removal of the pintle. These blocks C? may be glued into the mortises or fastened by any other known method. The edges of the bars A, opposite the barrels B and O, are made concave to correspond with the convex surfaces of the barrels, and the concave edges of the bars and the convexsurfaces of the barrels are made concentric with the pintles B, so that when the bars are united, as described, the edges of adjacent bars will form a hinged joint allowing the shutter to bend and be rolled up.
The pintles B may be formed integrally with the barrels B, or they may be made in separate pieces of either wood or metal and inserted in the ends of the barrels B. By the construction shown in Fi 2 a strain upon the door coincident with a line passing through the centers of the pintles will be received by the inserted block O and in Fig. 3 I have shown a form of construction in which this strain willbe received by the bar rels O, and it consists in forming the mortises, as represented at 0 upon the sides of the barrels O and at right angles with the line of strain passing through the pintles of the several bars. When the mortises are thus made, it will be necessary, in hinging the bars together, to place each pair of bars at right angles with each other, in order to enter the pintles B into the mortises G I deem the construction of the mortises as shown at O in Fig. 2 to be preferable, for the reasonthat the inserted blocks 0 are hidden from view when the door is extended, as represented in the drawings. The length of the barrels upon either edge of the bars can be varied as the judgment of the builder shall dictate.
The barrels B and O,instead of being formed integrally with the bars A, can be made in separate pieces and securely attached to the bars.
The barrels B and O are made cylindrical and concentric With the pintles B, and the edges of the bars between the barrels B B and O O are made concave and concentric with the axis of the pintles B, so as to fit the convex surfaces of the barrels and assist in holding the bars against lateral displacement, thereby relieving the strain upon the pintles B. The inserted blocks C by which the mortises are filled after the pintles are placed therein, serve to retain the pintles in place, but in some cases, where the mortises' are placed at an angle with the line of strain upon the pintles, as represented at C in Fig. 3, or in cases where the flexible shutter is designed to run in a groove, the blocks 0 can be omitted, the mortised barrels serving as hooks to engage the pintles B, which will be retained within the mortises, as the bars or leaves A will be restrained by the groove in which the shutter runs, and therefore held from lateral movement sufficient to carry the pintles out of their mortises.
hat I claim as my invention, and desire to secure by Letters Patent, is
edges with barrels, which are cylindrical in form and concentric With their hinging pintles, the edges of said parallel bars between said barrels being concave and concentric with the hinging pintles, pintles held in said barrels and entering mortises in the barrels of the adjacent bars and blocks inserted in said inortises in order to retain the pintles in place, substantially as described.
Dated the 13th day of January, 1891.
