INDICATOR FOR DESIGNATION STRIP HOLDER Filed Aug. 1, 1952 i 25 S 25 INVENTOR. l 2 E3 25 21 Dav/d] W6X/6! Patented Feb. 23, 1954 UNITED STATES PATENT OFFICE INDICATOR FOR DESIGNATION STRIP HOLDER 4 Claims. 1

. 'I'hev present invention relates to visual indicators, and more particularly to sliding indicators of this character which can be applied directly to an existing designation strip holder.

, There are many instances where, in addition to the usual designation strip, it is desirable to apply a manually operable visual indicator or visual signal device to the designation strip holder. Designation strip holders are used in conjunction with telephone switchboards, form holders such as hospital chart holders, and many other devices, and the visual indicator of the present invention is for the purpose of showing a particular or special condition, or that some action is to be taken or has been taken, when the indicator is operated to one of its positions.

Generally, the invention comprises a body member which is preferably H-shaped and adapted to be inserted into the designation strip of the indicator and be securely frictionally held thereby, a cover member longitudinally slidable with respect to the cross-bar of the H-shaped body and frictionally held in any desired position of adjustment, and indicia carried by the cross-bar of the H which may be covered or uncovered at will by sliding the cover member to appropriate positions.

Accordingly, an object of the invention is the provision of a visual signal device of this character which may be readily applied to a designation strip holder.

Another object of the invention is the provision of a device of this character comprising indicia and a manually slidable cover member which is movable at will to cover or uncover the indicia, as desired.

Still another object of the invention, is the provision of a device of this character wherein the body member is securely frictionally held in the designation strip holder, the cover member being relatively lightly frictionally held.

Other and further objects will become apparent upon reading the following specification together with the accompanying drawing forming a part hereof.

Referring to the drawing:

Fig. 1 is a front view of a designation strip holder with an embodiment of the invention applied thereto, the cover member being positioned to expose the indicia.

Fig. 2 is an enlarged fragmentary view, similar to Fig. 1, with the cover member positioned to cover the indicia.

Fig. 3 is a sectional view taken along the line 3-3 of Fig. 2, looking in the direction of the arrows.

Fig. 4 is an enlarged front view of the H -shaped body member.

Fig. 5 is a bottom view of the body member shown in Fig. 4.

Fig. 6 is an end view of the body member shown in Fig. 4.

Fig. '7 is a perspective view of the manually slidable cover member.

Referring to Fig. 1, a designation strip holder I I is shown secured by suitable fastening means, such as rivets [2, to a flat surface l3 of any desired object. The designation strip holder ll comprises extending rounded flat end portions I4 and two parallel inwardly turned flange portions l5. which extend lengthwise of the back or body portion I6, forming two longitudinal grooves or recesses I! adapted to receive therein a designation strip (not shown) of paper or other suitable material having any desired information appearing thereon. A suitable transparent strip may cover the designation strip, if desired.

An indicator embodying the present invention is shown inserted in the right hand end of the designation strip holder H, the indicator being designated generally as 20. The indicator 2!) comprises a generally H-shaped body portion 2| having a cross-bar 22 and four legs 23 extending outwardly from the cross-bar 22. The cross-bar 22 carries indica 24 on the left half thereof, which, in the embodiment illustrated, may be an area of distinctive color, such as red, for example.

The H-shaped body portion 2| may be formed of any suitable resilient material, but is preferably made of metallic spring material such as Phosphor bronze, for example. As may best be seen-in Figs. 5 and 6, the H -shaped body is curved forwardly about two mutually perpendicular axes, in this instance being both the vertical and horizontal axes, so that the four legs 23 extend forwardly with respect to the center of the crossbar 22. When the H-shaped body 2| is inserted in the longitudinal grooves I! of the designation strip holder II, the legs 23 resiliently engage the front walls of the grooves I! formed by the inner surfaces of the flange portions I5, the pressure of such engagement being sufilcient to hold the H-shaped body securely positioned within the designation strip holder l I.

A cover member 25 (Fig. '7) is shown provided with an outwardly curved central portion 26 and two tapering side portions 21 for sliding engagement with the longitudinal grooves I! of the designation strip holder II. The cover member 25 is shown provided with a. tab portion 28 which may be grasped to assist in sliding the cover member 25 along the longitudinal grooves H. The tapered side portions 21 of cover member 25 engage the longitudinal grooves 11 with sufficient frictional force to retain the cover member 25 in any desired position, but insuificient to prevent easy sliding of the cover member by hand, when desired.

The H-shaped .body member 21 and the cover member 25are inserted in the designationstrip holder II, as shown in Figs. 1 to 3. The legs 23 of the H-shaped body 2i limit the sliding movement of the cover member 25 along the longitudinal grooves ll of the designationstrip holder H. The force of frictional engagement of the legs 23 of the H-shaped body 2| with the walls of the grooves I1 is considerable, so that it may be displaced only intentionally. The indicia 24 .on

the cross-bar 22 of the H-shaped bodyZi may thus be covered or uncovered at will by'sliding movement of the cover member 25.
