CURTAIN FIXTURE STRUCTURE l Filed June 1956 j: INVENTOR j? LIDEEF'H EEHUNK.

ATTORNEY Patented Oct. 25, 1938 PATENT oFFIcE g CURTAIN FIXTURE's'rinro'rulsui` Joseph schunk, Newark, N. '1.,' assignor to The National Lock Washer Company,'N ewark, N. J., a corporation of New Jersey Application June 4,1936, SerialV No. 83,56-w i s claims.. (ol. 15e-26) The present invention relates to a curtain fixture structure, and particularly to the sliding head of the raising and lowering fixture of curtains, such as areused in railroad passenger cars, l: busses,and the like. 'Ihe raisingk and-lowering xture is mounted at the lower end of the curtain and is provided at each end with a head which operates in a metal channel at each side of the window opening. As heretofore constructed these heads were provided with rollers and metal sides, and from the lmovement and vibration of the car the head :would hit the side of the groove producing a very noticeable and objectionable noise. Itis an object of the present invention to provide a head which will be noiseless, and to this end it is proposed to provide the head with rubber shoes ateach end, which will come in contact with the sides'of the grooves when there is sufficient movement or vibration 2,0 to rotate-or slide the fixture in either direction,

thereby eliminating any noise that might otherwise be produced through contact of the head with the channel wall.

A further object is to provide a head which will slide easily in the groove, and will operate noiselessly during the raising and lowering of the curtain, due to the fact that metal to metal contact is eliminated and there are no movable parts, such as the rollers of the previous constructions, the bearings of which were apt to squeak if not frequently oiled.

Another object is to provide a retaining and releasing cam having a rubber facing for engaging the guide grooves, preventing marring or scratching of the groove and preventing noise that would result from metal to metal contact.

With the above and other objects in View an embodiment of the invention is shown in the accompanying drawing, and these embodiments will be hereinafter more fully described with reference thereto, and the invention will be finally pointed out in the claims. v

In the drawing: Fig. 1 is a front elevation of the lower end of a curtain, with portions broken away, showing the fixture according to the invention, one end of the fixture being partially shown in, vertical section. o Fig. 2 is a front elevation of the head, as used at one end of the fixture.

Fig. 9 is a bottom plan view. Fig. 10 is a side elevation of one of the metal inserts of vthe shoe. v

SimilarA reference characters indicate corresponding parts throughout the several figures of 10 the drawing. f v Y Referring to the drawing, Vthe curtain l0 has secured in its lower end, by means of a stitched hem portion Il, a xture consisting of a tubular rod I2yupon' each end of 'which a head according l5 to the invention is screwed, these heads 'being engaged and operablein metal channels Iii-,I3 at the Yrespective vertical sides of they window casing. A `plate lIII is secured centrally of the rod I2 by a screw I4@ and' is provided with a pair 20 of slots" I5I5 in which the finger grip portion I6- I6 of the locking cam operating rods I1 are engaged, these rods being normally pressed outwardly by meansvof a spring .I8 mounted upon each of them between a washer I9 secured in 25 the tubular rod I2, and through which the rods move slidably, and a washer 20 secured upon the rod I'I.

Inasmuch as the heads at each end are of identical construction, except that they are reversed 30 with respect to each other, only one will be described in detail. This consists of a sheet metal frame member 2| of U-shape in horizontal section and having a tubular socket portion 22 secured centrally to the inner side thereof, the end of the tubular member, 22 being contracted as at 23 to engage within an opening24 in the frame member, and being secured thereto by brazing or other suitable means. The socket member 22 is interiorly threaded and as above pointed out 40 is screwed upon at the end of the tubular bar I2. A locking cam member, consisting of a metal insert member 25 and a rubber facing 25a molded thereon, is mounted between the sides ofthe frame 2| upon a pin 26, and is normally pressed outwardly by the engagement therewith of the bent end 21 of the rod Il, being thus tightly pressed againstv the base of the channel I3 to retain the curtain. By pressing the finger grip portions |6-I6 toward each other the rods I1 50'v are retracted to release the cam members whereupon the curtain may be raised or lowered as desired. f.

The frame member is provided at its upper and lower ends with pairs of inwardly offset edges of the ears 28 are considerably longer than the inner edges.

The shoe members which are mounted at the upper and lower ends of the head upon Vthe ears --28 each consist of a resilient U-shaped rub:

ber member 32, one leg of which is longer than the other so that the ends of the legs-Will engage the shoulders and 3l while the shoe engages about the edges of the ears 28`--28, the rubber member being mounted upon an'insert member consisting of a pair of metal plates 33-33 having outwardly bent flanges 34-.3.4',-which are rem-f5.

bedded in the rubber and serve to lockthe rubber to the insert member and having'idia'gonal lower edges. vThe insert member is `centrally `of the central plane of the shoe and is engaged between the ears 28f28being secured thereto vby means of a pin 35 extending through apertures 36-36 in the ears and aperturesl 31-31 in the plates 33. 4 y

The rubber shoes project with respect to outer edges of the frame 2l, so that the outer surfaces of the shoe will engage the base of the channel I3 as the xtureis raised and lowered therein. The greater length of the outer legs of the shoes provides greater surface contact of the rubber against` the base of the channel Without increasing the height of the xture. The side surfaces of therubber shoes are projected with respect to the ears 28, so .that cushioning areas are provided at the upper and lower ends of the frame 2 I. It will be observed that any tendency of the fixture to turn in the channel or to vibrate will cause the cushion sides of the rubber shoes to engagegthe sides of the channel, eliminating all I have illustrated and described a preferred and-satisfactory embodiment of the invention,

but it will be obvious that changes may be made therein, within the spirit and scope thereof, as

' dened in the appended claims.

Having thus described my invention What I side channel of a window casing, comprising a frame having a pair of spaced ears at each end,

' and a pair of cushion shoes, one at each end, each comprising a metal insert member secured between saidV ears and a rubber member carried by said insert member surrounding the peripheriesof saidearsand projecting with respect to the side surfacesof said ears.

3. In combination, a tube, a curtain fixture' head rigidly connected to said tube for engaging the side channel of a window casing, said headl said tube normally pressing said gripping member outwardly to engage it with the channel base and to retain said frame out of contact with the channel base, a pair of rubber shoes, each projecting with respect to the edges of the open side of said frame to contact the base of the channel at each end of said open side upon` tilting about the point of contact of said gripping member Withthe channel base in the direction of the channel base and having exposed sides upon tilt.- ing` about the point of contact of said gripping member with the channel base in thedirection of the channel sides.
