HARRY n. SEVISON, or ELxHAn'r, INDIANA, ASSIGNOR T cur-IE ADLAKE ooMPANmor CHICAGO, ILLINOIS, A CORPORATION or ILLINOIS V CURTAIN FIXTURE Application filed July 22,

This invention'has to do with curtain 'fixtures of the type in which a pair of laterally spring-pressed holding members are carried by the lower end of an upwardly springdrawn car window curtain in frictional engagement with guides at the sides of the curtain.

In curtain fixtures of the type described, the holding members are retracted, when the curtain is raised or lowered, by a pair of centrally located finger pieces which are connected with the holding members. The finger pieces, however, usually rattle a little invention, other objects and advantages will be apparent to those skilled in the art' upon a full understanding of the construction, arrangement and operation of the novel silencing device.

One form of the invention is presented herein for the purpose of exemplification, but it will of course be understood that the invention is susceptible of embodiment in other structurally modified forms coming equally within the scope of the appended claims.

In the accompanying drawing:

Fig. 1 is a front View of a curtain fixture equipped with the silencing device of the invention I Fig. 2 is a longitudinal section through one of the duplicate ends of the fixture;

Fig. 3 is a transverse section, taken on the line 33 of Fig. 1; and

Fig. 4 is an interior view, showing the manner in which the double spring clip, which is secured to the inner face of the cen ter plate, embraces the finger pieces, one of 1929. Serial No. 379,910.

the finger pieces being removed for clear U ness of illustration. 1

The curtain fixture shown'in the drawing is structurally the same as that shown in Whitmore applicationSerial No. 330,171, and therefore need not be described in detail. Briefly, it consists of a tube 10 which is adapted to be encased inthe lower end of an upwardly spring-drawn window curtain.

The tube carries two outwardly springpressed' heads 11 which are adapted to ride up and down in two grooved guides 12 attached to the oppositesides of the associated window frame. outwardly spring-pressed'rods 18 which are connected at their inner ends to two'finger' pieces 14 and are connected at their outer] ends to two cams 15. The finger pieces 14 are adapted to retract the cams 15 away from the bottoms of the grooves in the guides,

while the cams 15 are adapted to wedge frictionally against the guides to prevent vertical movement of the fixture.

The finger pieces 14' are provided with flattened finger-engaging portions 16 on the outside of the tube, and with elongated interiorly threaded portions 17 within the tube at right angles to the portions 16, which interiorly threaded portions receive the inner threaded ends of the rods 13. A plate 18 is secured by a screw 19 to the tube over an opening in one side of the center of the same, and is provided with two axially elongated slots 20 through which the finger pieces 14 extend. 1 A pair of thin spring metal plates 21 having overlapping ear portions 22 are secured against the inner face of the plate 18 by an eyelet 23 which extends about the edge of the screw aperture in the same. The spring plates 21 are provided with: inturned flanges 24, in opposed pairs, which flanges press resiliently against opposite flattened surfaces 25 on the rod-engaging portions 16 of the finger pieces, whereby to hold the finger pieces snugly against any sidewise movement. The normal spacing of the flanges 24, with the finger pieces removed, is slightly less The tube also carries two.

than the distance between the flattened sur I faces 25 on the finger pieces, with the result holding members, finger pieces for retract- .30

that, when the finger pieces are inserted, the flanges bear resiliently against the sides of the same with a certain amount of pressure. I 'The provision of the silencing device does not add materially to the cost of the fixture,

but does greatly enhance the value of-the same by reason of the way inWhich 'it effectlvely ehmlnates the noise. heretofore caused by'the'sidewise movement of the fin I ger pieces; While the silencing device has been illustrated anddescribed herein in connection with one particular form of curtain fixture, it will or" course be appreciated that it is equallyv applicable to various other forms of curtam fixtures havlng finger pleces for use in operating the same.

I claim: V 1. In a curtain fixture, means for holding a curtain against upward movement, means for retracting the holding means, and means acting against the retracting means to prevent the same from-rattling. I

2. In a curtain-fixture, normally extended holding members, finger pieces for retracting thesame, and means acting against the finger pieces to prevent the same from rattling While the holding members are extended.

3; In a curtain fixture, normally extended ing the same, spring means bearing resiliently against the finger pieces to prevent. the

'same from rattling While the holding m'em bers are extended. 4. In a curtain fixture, a tube, upwardly spring-pressed holding members at theends of the tube, finger pieces projecting laterally from one side of the tube at the center of the same for retracting the holding members, and spring clips compressibly embracing the portions of the finger pieces within the tube to prevent the finger pieces from rattling.

. 5. In. a curtain fixture, a tube,'outwardly spring-pressed holding members at the ends i of the tube, a plate attached to the tube over an opening in the center of-one side of the same, finger pieces connected Within the tube to the holding ;members. and projecting laterally through elongated slots in the plate for retracting the holding members, and spring clips carried by the plate Within the tube and compressibly.embracing the portions of the finger pieces Within the tube to prevent the finger pieces from rattling.

' In Witness WhereofI have hereunto subscribed my name.

HARRY D. SEVISON.
