CAM OPERATED MASTER SLIDE Filed Jan. 13, 1960 2 Sheets-Sheet l INVENTOR. BOB W. WILLS W @M ,74M

ATTORNEVS B. W. WILLS April 2, 1963 CAM OPERATED MASTER SLIDE 2 Sheets-Sheet 2 Filed Jan. 15, 1960 ATTORNEVS rates This invention relates to traverse rod structure and particularly to a master slide for use on and with a traverse rod which will hold the curtains or drapery in substantially coplanar alignment with respect to each other when same are open, which will hold same closely against each other when same are overlapped in closed position but which will avoid interference between said curtains as the same approach each other in going rorn open to a closed position.

In conventional master slide construction for traverse rods, it is customary to offset either or both of said slides stnficiently that they and the curtains carried thereby will clear each other as said slides are moving the curtains from an open to an overlapped, closed, position. This is generally satisfactory but it requires some offsetting of the curtains with respect to each other. Thus, since the overlapping portions of the curtains are in such cases offset with respect to each other sufficiently that there is no interference between said curtains as they move from open into an overlapped closed position, the curtains are often spaced sufficiently from each other that they are quite unsightly when in a closed position in view of the space existing between them. Further, since the line or" support for the slides is in a single straight line, namely, the traverse rod track, it necessarily means that one or both of said master slides will have the weight of the curtain offset from a position directly below the point of support of said slides. This is not harmful in curtains of relatively light weight, but it is more serious in larger and heavier curtains. In such latter cases, there is often suflicient twisting of the master slide as to cause undesirable wear on the portions thereof engaging the traverse rod track and undesirable drag in the operating of the curtains.

ccordingly, the objects of the invention are:

(1) To provide a pair of master slides for a traverse rod construction which will hold curtains in substantially coplanar alignment while same are in open position, which will move at least one thereof sidewardly away from the other to provide clearance between said curtains as they are moving from an open into an overlapped position and which will then close said curtains against each other when the overlapped position is obtained to promote a smooth and uninterrupted appearance on the part of said overlapped curtains.

(2) To provide a device, as aforesaid, which will onable both of said curtains to be suspended substantially below a supporting track of the traverse rod structure in substantially all open and closed positions thereof.

(3) To provide master slides for a traverse rod, as aforesaid, which will move one edge of at least one of a pair of normally coplanar curtains laterally with respect to the facing edge of the other curtain as said curtains are approac ring each other and then when they have attained an overlapped, closed, position will close said curtains tightly against each other.

(4) To provide master slide construction for traverse rods which will function automatically, as aforesaid, as said master slides are moved toward each other and as they attain overlapping relationship with respect to each other.

(5) To provide master slides for traverse rods, as aforesaid, which will be sufficiently simple as to be capable of relatively economic construction and will require a minimum of maintenance.

Patented Apr. 2, 1963 ice (6) To provide master slide construction for traverse rods, as aforesaid, wherein the movements aforesaid can be accomplished without imposing appreciable additional drag upon the movement of the master slides.

(7) To provide master slide construction, as aforesaid, which will not look appreciably different from the master slides in previous common use and wherein. the manner of fastening the curtains to said slides will be the same as in previous common use.

Other objects and purposes of the invention will be apparent to persons familiar with devices of this general type upon reading the following specification and examination of the accompanying drawings.

Definitions For the purpose of convenience in reference the following definitions will apply:

The term forward or front shall refer to the portion facing away from the wall in normal use: of the apparatus, the same being the side seen in FIGURE 1. The term rearward or backward will refer to the part facing toward the wall and normal use of the traverse rod, the same being the side appearing in FIGURE 2 of the drawings. The terms upward and downward will refer to upward and downward directions of the parts in their normal position of use. The terms rightward and leftward will refer to the directions rightwardly and leftwardly as appearing in the drawings and particularly with respect to a given drawing to which reference is made when and as the terms are used.

Each of these terms will include derivatives of the words above specifically mentioned as well as words of similar import.

General Description In general, the invention consists in providing master slides having curtain-supporting members normally positioned substantially below the point of support of the master slides on the traverse rod tracks and coplanar with respect to each other. One portion of at least one curtain-supporting member is jointed to move laterally and thereby offset its leading edge laterally from the opposed leading edge of the other curtain-supporting member. Cam structure is provided interacting between said master slides and opposed by resilient means whereby said jointed section will normally lie coplanar with the remaining portion of the member of which it is a part but will move outwardly as above mentioned as the two slides approach each other and as the curtain-supporting members enter overlapped position with respect to each other.

Detailed Description Turning now to the detailed construction of apparatus illustrated in the drawings and embodying the invention,

mention is first made of the traverse rod with which said master slides are used. It will be recognized that there are several forms of traverse rods with which said slides may advantageously be used so that the choice of the particular traverse rod structure here used to illustrate the invention will be recognized as illustrative only and not limiting.

As shown in the drawings, there is provided a traverse rod member 1 having a generally oval shape and wherein one side is interrupted to provide the

coplanar tracks

2 and 3. The other traverse rod member 4 is slidably received into the first traverse rod member 1 in a conventional manner. An end bracket 6 is indicated for holding said traverse rod structure in a desired position upon a wall in the usual manner.

The leftward master slide 7 is slidably supported within the traverse rod structure and cooperates with the rightward slide structure 8 which is similarly slidably supported within said traverse rod structure. Each of said slides carries an end of the curtains supported by the traverse rod and is caused to move toward and away from each other in a known manner by traverse-controlling mechanism not here shown. The specific structure of said controlling mechanism forms no part of the present invention, is well known to the industry and hence has been omitted from both the drawings and the description thereof in order to avoid unnecessarily complicating this disclosure.

Looking now at the leftward slide 7 in more detail, and referring particularly to FIGURES 1 and 7 for showing opposite ends of said member, it will be seen that said slide includes a plate portion 9 which carries slides 11 and 12 which slides are of any convenient material, such as nylon, and are received into the slot defined by the edges or tracks 2 and 3- of the traverse rod. A curtain-carrying portion 13 extends downwardly from the plate portion 9 and is provided with a plurality of openings 14 and 15 (FIGURE 2) by which the curtain is hung onto the master slide 7 in the usual manner.

Extending rearwardly from the plate portion 9 is the cam portion 16 which is of somewhat V-shape with V the V portion opening forwardly. Said cam portion 16 has an opening 17 extending therethrough at the apex of the V and located at a point substantially spaced from each end of the cam section 16.

Turning now to the master slide 8, this comprises a body portion 21 (best shown in FIGURE 7) which is supported within the track of the traverse rod by the

slides

22 and 23 which slides will normally be identical with the slides 11 and 12. Said body portion 21 is provided with tabs 26 and 27 (see also FIGURE 6) extending rearwardly therefrom, said tabs being spaced vertically from each other and being both arranged sub stantially perpendicular with the plane of the body portion 21.

The curtain-carrying arm 28 of the rightward slide 8 is provided with openings 29 and 30 (FIGURE 1) for the reception of curtain hooks in the usual manner and has a U-shaped mounting portion 31 (FIGURES 1, and 6) at that end thereof which is rightward in FIG- URE 1 and leftward in FIGURE 5. Said U-shaped mounting portion 31 extends between the flanges 26 and a provide a generally rounding shape as best appearing in FIGURES 4 and 7.

A spring 42 is anchored at 43 to the body portion 21 of the rightward slide 8 then bends around the pivot portion 37 and is anchored at 44 (FIGURES 5 and 6) to the movable arm portion 28 of said rightward slide 8.

The limiting tab 46 (FIGURES 3 and 7) is provided on one flange, here the lower flange, of the U-shaped member 3-1 and is arranged to strike against an adjacent portion of the body part 21. Thus, the rotation of the arm 28 about the pivot 37 in response to the urging of the spring 42 is limited at such a point that the arm 28 is substantially parallel with and offset slightly from the curtain-supporting portion 14 of the leftward slide 7 (FIGURE 3).

Operation Starting with the master slides separated as shown in FIGURE 7, it will be noted that the arm 28 is substantially parallel with the transverse rod so that the adjacent edges of curtains carried on said master slides will be very close to coplanar with respect to each other. As the slides approach each other the cam follower 41 engages the forward surface of the cam 16 and rotates counterclockwise as viewed in FIGURE 7. This rotates the arm 28 around the pivot member 37 and against the resiliency of the spring 42 to occupy the position shown in FIGURE 5 (where, inasmuch as this is viewed from the under side as compared to FIGURE 7 which latter is viewed in part from the upper side, it is shown as having completed a clockwise rotation). This separates the adjacent edges of the curtains by a substantial margin so that there is no interference of either by the other as the slides continue to approach each other.

When the slides attain their fully closed position, as shown in FIGURES 1 to 4, inclusive, the cam follower 41 encounters the opening 17 and is able then to respond to the urging of spring 42 and move again until the tab 46 terminates such movement and the arm 28 is again parallel with the traverse rod and in overlapping relationship with the curtain-carrying part 13 of the leftward slide 7 (as best shown in FIGURE 3). The curtains are now overlapped but lying closely together so that there is no discernible space between them.

In opening the curtains, the above-described action is reversed and no appreciable drag exists between the over lapped portions of the curtains as the same are opened.

Thus, the action is direct and simple and is fully capable of accomplishing the objectives of the invention as set forth above.

Although a particular, preferred embodiment of the invention has been disclosed above for illustrative purposes, it will be understood that variations or modifications of the above disclosure are contemplated unless specifically stated to the contrary in the appended claims.
