(Cl. 156-26) bers will be described in detail. As shown in Fig. 4, the left-hand head i2 is provided with a stern I9 which extends into the lend of the tube I0 through a hole in a wood block Ziì which is fixedly a part of a turn in either direction. The im proved fixture is of pleasing appearance, can be positioned in the wide intermediate section I3 manufactured inexpensively, is absolutely noise `of the tube. The hole in the block 25 forms a guideway for the stem of the head to slide back less and will hold a curtain ñrmly in any posi and forth in, and the outer part of the hole is -tion in which placed.

The spring 2l tends at all times to project the'head I2 outwardly into firmly hold ing frictional engagement with the guide I3. A Vpreferred embodiment of the invention is pre sented herein, but it will of course- be appreciated that such embodiment is intended primarily for the purpose of exemplification and that the in vention is susceptible of being embodied in other structurally modified forms coming equally with 20 in the scopeof the appendedclaims. In the accompanying drawing: Fig. 1 is an inside front View of a window cur tain assembly equipped with the new fixture; Fig. 2 is a vertical transverse section through 25 the íixture, taken on the line 2_2 of Fig. 1; Fig. 3 is a similar section, taken on the line 3-3 of Fig. 1; Fig. 4 is a vertical longitudinal section through one end of the ñxture; 30 ` Fig. 5 is a horizontal section, takenon the line 5_5 of Fig. 4; f f Fig. 6 is a horizontal section through the center of the fixture, taken on the line 'ii-_6 of Fig. 1; and 35 Fig. 7 is a vertical longitudinal section, taken on the line 1_-1 of Fig. 6. i As will be observed in the drawing, the fixture includes a tube lll, an operating knob II midway between the ends of the tube, and heads I2 be 40 yond the ends of the tube. The tube Ill, which is preferably made of either sheet or extruded metal, is vertically elongated in cross section, with narrow upper and lower sections and a rela tively wide rectangular intermediate section I3, 45 and is provided along its upper edge with a par tially closed groove I4 in which the lower edge The inner end of the stem lil is threaded into a small sleeve 2li which is slidably mounted in an enlargement at the inner end of the hole in the block 2li, and the sleeve 24 is in turn pivotally attached to one end of a long rod 25. The end of the sleeve 2li which is connected with the rod 25 is bifurcated, as best shown in Fig. 5, and ther adjacent end of the rod 25 is iiattened to fit within the bifurcation. A pivot pin 2li is mounted in the bifurcated end and passes through an aperture in the ñattened- portion of the rod, which aper 25 ture is elongated axially of the rod to permit of a certain amount of endwise movement of 'the rod relative to the sleeve and its associated stem and head. This endwise movement is normally prevented by the resistance of a spring 2l which is mounted on the rod 25 near the pivotal con nection and is compressed between a washer 28 secured to the rod and another washer 29 abutting against the end of the sleeve. The far end of the rod 25 terminates adjacent the location of the knob I I in two oppositely spring-pressed strips 30 which are riveted to the rod and are provided at their free ends with laterally projecting studs 3l. The rods 25 leading to both heads are connected to a rotatable hub 32 which is located in the tube I0 behind the knob il. The knob has a reduced neck portion 33 which is journaled in a circular aperture cut in the front face of the tube, and the hub 32 is clamped to the inside face of the knob by a screw >35i which passes through the center of the knob and is threaded into a recess of the curtain I5 is securely held rby a small filler ’ in the center of the hub. The end of the hub rod I6 inserted from one end of the tube. which is clamped to the knob is larger than the The heads l2 are preferably equipped with rub 50 ber blocks Il, but they may befurnished with neck portion and accordingly locks the knob any other suitable device for frictionally engag« against outward movement. The hub is centered ing with the’ vertical guides I8 at the sides of on the knob by means of the screw 364 and is the window opening. As both of the heads I2 caused to turn positively with the' knob by means> and their associated control members are the of a rib 35 on the inside face of the knob which 55 same, only one of the heads and its control mem lits into a complementary groove 35 on the ad 2 ,2,113,837 I claim: f1.Y In a curtain fixture, an outwardly movable head at one end of the fixture for engagement with a guide at one side of the curtain, a spring for pressing the head outwardly, a rod connected jacent end of the hub. The hub 32 is of gener ally cylindrical shape, with segments cut out of opposite sides between the ends, which segments leave two pairs of spaced ears 3l. The strips 30 on the inner ends of thel rods 25 are sprung together to ñt between the ears 31, and when so fitted the studs 3| on the ends of Vthe strips snap into recesses in the ears and establish pivotal con ` with theV head, a rotatable operating member con- ' nected at a point eccentrically thereof with the rod, and a resiliently yieldable coupling between nections between the Y_ends of the rods andthe 10 hub eccentrically of the axis of the latter. The strips 30 are preferably provided, in the spaces between the same, with yieldable pads 38 of felt or other suitable cushioning and sound-deadening material. Near the hub 32 the rods 25 are provided with 15 springs 39 which project upwardly and down wardly at an angle from the rods andare pro vided with bent foot portions 4D which abut with the inside walls of the tube I0 in the enlarged intermediate section I3 thereof. These springs, in addition to supplementing the action of the»V springs 2l in tending to force the heads into en gagement with the guides, tend to keep the-rods 25 centered in the tube and free from all up-and 25 down as well as sidewise play. ‘ Y When the fixture is first installed, the heads saidoperating member and said rod so con structedrand arranged as to permit the operating 10 member to berrotatableV in eitherA direction pastV the dead center Yposition of the rod in retracting the head.

V3.V In a curtain fixture, an outwardly movable head at one end of the fixture for engagement with a guide at one side of the curtain, a spring for pressing the head outwardly, a sleeve thread inglyV connected with the head, a rod pivotally connected with the sleeve, a rotatable operating I2 are screwed either in or out in the sleeves 24 in order to cause the heads to engage with'the , member connected at a point eccentrically there guides I8 just'before the pivotal connections be- ' of with the rod, and a resiliently yieldable cou pling at the location of the pivotalconnection 30 30 tween the hub 32 and the rods 25 reach their between the sleeve and the Vrod so constructed dead center positions. Y Y , Torretract the heads from the guides in rais and arranged as to permit the operating mem ing or lowering the curtain, it is merely necessary ' to rotate the knob II a part of a turn inY either 35 direction. It doesn’t make any difference inVv what direction the knob is turned because if it Vis started in a direction which would project the' heads instead of retract them the rods'25'wil1 pass through their dead center positions without 40 any diñiculty due to'the resiliently yieldable cou plings in the rods aiïorded by the springs 21. In assembling the several parts of the fixture at the time of its manufacture, the rods 25 are hooked up with the hub 32 and all of the :insideVV 45 mechanism is then threaded through Vthe tube I0 at the same time.
