ROBERT F. GOLDEN, OF SOUTH ORANGE, NEVI JERSEY, ASSIGNOR TO THE NATIONAL LOCK WASHER COMPANY, OF NEWARK, NEW JERSEY, A CORPORATION OF NEW JERSEY.

CURTAIN FIXTURE.

To all whom it may concern:

Be it known that 1, ROBERT F. GOLDEN, a citizen of the United States, residing at South Orange, county of Essex, State of New Jersey, have invented certain new and useful Improvements in Curtain Fixtures; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains, to make and use the same.

This invention relates to curtain fixtures, in which a spring tension roller is employed at the top and constantly tends to wind the curtain, the latter being equipped at the bottom with what are known as curtain rods that are provided at their inner ends with finger pieces which are pinched toward each other to draw the rods inwardly against the resiliency of springs that surround them, these rods being usually connected at their outer ends to cams that are carried by heads that track in grooves at the sides of the window casing.

This style of curtain fixture is well known and is commonly used on the curtains of railway car windows, and the present invention has reference solely to the rods and the cams that are carried by the trackin heads.

Referring to the accompanying drawings Figure 1 is a front elevation of the ourtain fixture as it appears when properly engaged with the side grooves of the casing, one end portion being shown in section.

Figure 2 is a broken section at right angles to that shown at Figure 1, and

Figure 3 is a detail broken perspective view of the outer end of the rod showing a modification thereof.

Similar numerals of reference denote like parts in the several figures of the drawing.

In curtain fixtures of this description it has heretofore been the practice to connect the outer end of each rod with its cam so that when the rod was pinched inwardly it would withdraw the cam.

According to the present invention, there is no connection whatever between the rod and cam, and when the rod is drawn in wardly it does not withdraw the cam with it.

As there are two rods, one for each end of the fixture, and as these rods are identical in form and function, only one of such rods will be described.

1 is the tube that is secured to the bottom of the curtain, 2 the finger piece and 3 the rod surrounded by a confined spring 4, all constructed and assembled as heretofore.

To the outer end of the tube is screwed the shank 5 of the head 6 which latter at its ends has the usual track rolls 7 that travel in the usual groove in the window casing.

The outer end of the rod 3 is formed into a laterally extending portion 8, which engages between the sides of the head 6 so as to prevent the independent rotary movement of the rod. As shown at Figure 1 this part 8 is in the form of a hook merely because this is a very cheap way of providing a laterally extending portion and not because any function is to be performed characteristic of a hook, and the end of the rod may be flattened so as to provide a laterally extending part 9 as is shown at Figure 3. In both instances the laterally extending portion provides means cooperating with the head for preventing the independent rotation of the rod, and in this connection attention is called to the fact that a cross-pin through the end of the rod or mere side fins formed thereon are fully within the scope of this invention, the gist of which rests in the broad idea of so equipping the outer end portion of the rod that it will only be revolved by rotation of the head and yet will have no actual connection whatever with either the head or the cam 10 which latter is pivoted at its lower end within the head.

In assembling the structure, the rod is inserted within the tube and the head placed over the rod so that the portion 8 is located between the sides of the head, and the latter is then revolved so as to cause the shank 5 to screw on to the rod and at the same time cause the inner end of the rod to screw within the threaded socket 11 of the finger piece 2.

The portion 8 will always be normally projected against the cam 9 to force the latter beyond the head into frictional contact with the track, but when this rod is withdrawn by manipulation of the part 2, the cam no longer is backed by any force whatever and will therefore readily yield to permit the ready operation of the curtain.

This assembly of the rod free of any connection whatever at its outer end does not impair the efficiency of the fixture in the least, but it does enable the fixture to be furnished at considerable less cost than heretofore since many operations are dispensed With, taking into consideration that there 5 are two rods to a fixture.

What is claimed is In a curtain fixture of the character described, the combination With the tube, the central fingerpiece socket, the head threaded 10 on the tube, and thggarn Within said head,

of the resiliently acting rod threaded at its inner end Within said socket and having at its outer end a laterally extended portion that is freely housed between the sides of the head, is rotated by the rotary movements of said head, and is normally projected against said cam.

In testimony whereof I affix my signature hereto.

ROBERT F. GOLDEN.
