REFLECTOR SIGN Filed Aug. 16, 1953 ATTORNEY Patented Sept. 25, 1934 y mais; "REFLECTGB SIGN menare w. r.uce,wesm1a,`1v.lx, miniera Signal. Service Corporation, a corporation of Delaware Application Angustia,

'Ihis invention relates particularly to the mounting of reflector buttons in sign plates or boards of natural or artiiicial wood or like fibrous material which can be readily pierced with a sharp instrument.

Inaccordance with this invention the button employed has a limiting circumferential flange or collar near its front end and the button body is of a size to'enter a hole bored in the face of the mounting until the flange or collar strikes the outer face of the mounting. The body is provided however, with protuberances such as sharp barbs, for example, which extend beyond the wall of the hole and pierce the material. As the button is forced in by pressure against its outer end,

the protuberances bite into or pierce the wall and secure the button in the hole.

When barbs are used hey wili preferably be inclined to the axis so as o have a spiral disposition and thus cause the button to rotate as it is forced into the hole, the barbs describing a spiral path in the wall. Preliminarily the wall will preferably be treated to seal the pores and exclude moisture. The barbs will most convenient- 1y be formed on a separate clip applied to the button.

I shall now describe the illustrated embodiment Y Fig. 1 is a cross section through a button ren ceiving hole in a sign board mounting with a button shown in place and with a mounting tool immediately above the button.

Fig. 2 is a plan of the barb carrying clip shown applied to the button in Figure 1.

Fig. 3 is a side elevation of the clip.

Fig. 4 isa view similar to Figure 1 showing a slightly modied form of mounting.

In the form of mounting shown in Figure l, the board 1 has a cylindrical hole 2 bored therein, of a size to receive the body of the button 3 with a fairly tight iit: The hole is first treated with shellac or paint to seal the pores of the wood and keep out moisture. The iiange 3a on the front end of the button is of a. size to abut against the vfront face of the mounting and thus provide an overlap to seal the opening.

At the bottom of the cylindrical wall of the button body are provided two diametrically 'opposite securing lugs 3b and 3c. On these there is secured the clip 4 shown in detail in Figures 2 and 3. This clip is of sheet metal and has a bottom plate portion 4a with arcuate ends and upstanding from the ends are the arcuate flanges '55 AMaand 4c, one at each end. These flanges are 1933, Serial No.'685,428

provided with ahole or recess which receives and interlccks with the respective securing lug 3b or 3c. Thus the clip is locked on to the b'ody.-

One corner of each flange 4b and 4c is bent back to form a barb, the two barbs being formed on corresponding corners of the flanges and being substantially equally inclined to the axis of the button so as to have a spiral relation. p 'I'he barbs are numbered respectively 4b' and 4c and they extend well beyond the wall cf the hole when the button is centrally disposed therein. Consequently they pierce into the wood and securely hold the button in place against any pulling force which can ordinarily be applied to the outer end o of the button.

To insert the button a tool 5 such as shown in Figure 1 may be used. This has a socket of a size and shape to receive the end of the button with the peripheral edge resting on the flange 3a. Mallet blows on the outer end of the tool so set will drive the button into its hole and cause the barbs to cut a path along the wall.

lSince the barbs are spirally disposed they willv traverse a spiral path as'the button is forced longitudinally. In other words the button as a whole will rotate as it descends.

Where itis desired tol recover the button after a short period of use, the hole in the mounting should be drilled entirely through as shown at 2a in Figure 4, and a back plate 1a placed over the rear of the sign plate as shown. To recover the reflector the back plate is removed and the reflector mayy be driven out from the rear with a flat faced tool without any injury to the reflector.

It is obvious that the construction illustrated and described can be otherwise variously modiiled without departing from the spirit or scope of the invention as expressed in the appended.

claims.

I claim:

1. A sign construction comprising a mounting of fibrous material having a button receiving hole in one face thereof, a reflector button the body of which is entered intol said hole, and sharp pointed barbs spirally disposed on the body extending outwardly beyond the wall of the hole into the material of the mounting.

2. A signconstruction comprising a mounting of fibrous material having a button receiving hole in one face thereof, a reflector button the body of which is entered into said hole, and a clip secured on the body and provided with a plurality of barbs inclined to the axis in the same direction and having their ends extending into the material of the mounting .in retoining relotion.

3. A sign construction comprising o, ounting of fibrous materiel having o button receiving hole in one foce thereof, a. reflector button the body of which is entered into seid hole, end e clip secured upon the inner end of the body ond having two opposed outwardly turned herbs inclined to the exis in the some direction so es to cause the button to move spirelly es it is forced into the hole, the ends of the barbs having their ends extending into the material of the mounting in retaining position.

d. A sign comprising o Wooden sign boord hoving o button receiving hole in one foce, e, reflector button the body of which is inserted into Vthe hole, end a. clip localizedv to the inner end of the body and having two opposing orcuote onge portions disposed circumferentielly of the body, corresponding corners of the flange portions loeing bent out so os to form spirallv disposed herbs the ends of which extend into the wooden well of the hole and hold the button in the hole.

5. l eign construction comprising a. mounting heving o button receiving hole in one fece thereof, e, renector button the body of which is entered into seid hole, ond e clip secured on the body ond provided with on element driven into the meterinl of the mounting in retaining relation. Ci. For signs the symbols of which are defined for redector buttons set into holes provided in e. support thereior, o reflector button, a clip therefor includhig en element adopted to pierce the support secure the clip thereto, and means for securing the reflector button to the clip.

l. For signs the symbols of which are defined by reector buttons set into holes provided in a support therefor, e. reiiector button, a, clip therefor including herbs adopted to pierce the support end eeonre the clip thereto, end complementery interlocking projections end recesses on the hutten sind clip for securing the button to the clin.,
