SIGN HOLDING DEVICE Henry C. Yfafi, Jr., East Orange, N. .l'. Appiication June 15, 1937, Serial nof-iiazts 2 Claims. (01. 40-445) This invention relates to improvements in Fig. Z'iswaperspectiVe view of the two part street sign display devices and more particusign plate holding frame, embodying my inven larly to devices of the type described in U. S. tion, i

The construction dein which: scribed also precludes the danger of excessive Fig. 1 is an elevational View of the device when expansion and contraction of the frame due to used to indicate two intersecting streets, parts climatic conditions. being broken away for the sake of clarity, Each of the parts 6 and l is substantially U- 55 rotated to draw the parts firmly together. Up- V shaped and has on opposite sides semi-cylindrical bosses H and I2 so that when the frame is assembled, the bosses fit together to provide cylindrical bosses as shown in Figs. 1 and 3. An external rib l3 preferably triangular in cross sec tion, as shown in Fig. 2 extends around the periphery of the frame.

Passing through the bosses II and I2 is a rod H, (see Fig. 3) which is preferably provided with a cap- I 5 integral therewith or threadedly secured thereto, said cap having opposing triangular grooves i6 adapted to fit over the rib l3 of the frame, the internal diameter of the cap 15 being greater than the diameter of the cylindrical boss formed by the bosses H and I2. The cap is usually provided with an integral ornament H.

When for example two sign plates are used to designate two intersecting streets the top rib is of the upper frame is engaged by the cap [5, while the bottom rib on the upper frarne is engaged by opposing triangular grooves IS in a collar I9 which surrounds the bosses on'the lower side of the upper frame and on the upper side of the lower frame, (see Fig. l), the collar 19 having grooves Hi to also engage the upper rib of the lower frame. The lower rib 13 on the lower frame fits in grooves Zl ina collar 22 integral with a two-part cap 23 which fits over the top of and is clamped. by suitable means'to a cylindrical supporting post 24. The lower end of the rod H5 is preferably threaded and passes through an aperture in cap "23.

In assembling the device, cap 15 is fittedover the bosses II of the upper frame, the rod M passing through the bosses H and between the sign plates 9 which are bowed or spaced at the center by thestrips H] to receive the rod 14, and the collar 13 is then slipped over the rod 14 and into position over the bosses on the underside of the upper frame; the lower frame members are then placed in position with the upper bosses il thereon surrounded by collar 19.

The cap 23 is then positioned over the lower bosses 12 of the lower .frame after which a 'nut 25 is threaded on the end of the rod 1'4 and 'I have provided a sign holding device of simple structure requiring no nuts or bolts, and which can be readily assembled by a single unskilled workman. The parts are fitted together so that allowance can be made for limited expansion and contraction due to changing weather.

The foregoing disclosure is to be regarded as descriptive and illustrative only, and not as restrictive or limitative of the invention, of which obviously embodiments may be constructed, in-

cluding many modifications, without departing vfrom the general scope herein indicatedand de- Inoted in the appended claims.

Having thus described my invention, what I claim as new'and desire to secure by Letters Patent, is:

1. In a sign holding device, a frame member comprising a pair of substantially U-shaped internally channelled sections, each section having bosses at the free ends of the legs thereof,

'- means surrounding said bosses to hold the sections together, and members connecting the legs of each section adjacent the bosses, said members being positioned on the longitudinal center lines of said sections.

'2. In a sign holding device, a frame member comprising a pair of substantially U-shabed internally channelled sections, each section hav-- ing bosses at the free ends of the legs thereof, cylindrical collars surrounding said bosses to hold sections together, and members connecting the legs of each section'adjacent the free ends thereof, said members being positioned on the longitudinal center'lines of said sections.
