CURTAlN-STRETCHER BAR.
srncrrrclrrron forming part of Letters Patent No. 617,813, dated January 17,1899.
Application filed May 25', 1896- nois, have invented a new anduseful Improvement in Curtain-Stretcher Bars, of which the My invention relates particularly to that class of bars used in frames for stretching lace curtains while drying in which the pins are made movable, so as to engage the meshes of the lace curtain at such a point that it will. exert constraining force upon the .curtain'in but one direction, and thereby prevent a lateral force often found in frames where the barpins are made stationary, and the object of my invention is,.first, to make a pin that shall- Fig. 4 shows a pin with a base consisting of a piece of metal with a pin soldered or riveted thereto.
- Similar letters refer to similar parts throughout the several views. Y i
0. represents a section of the bar, having a rabbeted edge on its upper surface. Opening on this rabbeted edge is the T-slot c, in which slide the pins dd. In Fig. 3 I have shown the base of the pins din two shapes, round and square; but it is evident that they might have any one of an infinite number of shapes if made to fit in the base of the T-slot. It is also evident that the basemight have a different shape, makingan L-slot or any simi-' lar shape. I
The pins are made to move freely in the slot; but when the curtain is stretched upon the when tilted such base will b'ea a" n Serial No. 593,077. (No model.)
' frame the pins will be drawn over to the'position indicated by the dotted line e in Fig. 2, and the base of the pin will be held rigidly against the sides'of the slot, so as to prevent sliding, thereby giving all the advantage of a Stationary pin while in use and of a sliding pin when adjusting the curtain,
A'pinwith a metal basea'nd having the upright piece soldered, or riveted thereto, as shown in Fig. 4, I have found quite satisfactory, but prefer thepin shown in Fig. 3, as it can be stamped out of a single piece of wire,-
thereby lessening the cost to manufacture,
and the pin formed in this way is very durablei Having thus described my invention, what I desire to secureby Letters Patent is+ 1. A curtain-stretcher bar, having a rabbeted upper edge, a T, or similarly-shaped slot, opening upon the rabbeted upper edge, a pin with'a metal base and so constructed that the said pin shall extend upwardly from 'said base, made movable in said slot, the
metal base of said pin and the slot being so proportioned'that when tilted suchbase will. bear against both sides of the slot, thereby preventing the sliding of theqpin,-subs tan- 'tially as and for the purpose set forth.
2. A curtain-stretcher bar, having a rabbeted upper edge, a T, or similarly-shaped slot, opening upon the rabbeted upper edge, a-pin'having a base formed out of a single piece of wire and so'const'ructed that the said pin shall extend upwardly omi saidjbase', made movable in said sl0t.-=ith has of said pin and-the slotbeing so pi pertien-e sides of the slot, thereby preven ing of the pin, substantially as and -:for the purpose set forth.
