WARREN A. SHERWOOD AND EDWIN L. GARDNER, OF LANCASTER, PENNSYLVANIA.

ILLUMINATEID SIGN.

To all whom it may concern:

Be it known that we, WARREN A. SHER- wooD and EDWIN L. GARDNER, citizens of the United States, residing at Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in Illuminated Signs; and we do hereby 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 illuminated signs and has for its object to provide a more evenly distributed light and easy means of access to the source of illumination.

In the signs now in use the light is thrown upon the sides unevenly, as the light gets weaker, so that the parts farthest from the source of illumination receive less light than those closer to it. In this invention the light is equally distributed, the source of it is made easily accessible and the same is readily returned to and held in its proper place.

To these ends and for the general improvement of the sign our invention consists in the construction and combination of parts hereinafter set forth and claimed.

In the accompanying drawings Figure 1 represents a vertical section of a sign embodying our invention; Fig. 2, a detail view of the triangular check and ring; Fig. 3, a detail view of one of the T-irons; Fig. 4., a detail view of part of the bottom of the trough reflector the catch and head of the supporting rod; and Fig. 5 represents in detail sectional view the trough reflector in its lowest position, for access to the light, showing proximate parts.

A A designates the two concave upwardly diverging reflectors secured at their upper edges to the sign case B. These reflectors may be covered with some enamel of any color or may be left uncovered, being of polished metal. They are fastened together at their converging lower ends preferably by a screw tapped plate C or they may be brought together and fastened in any suitable way. By arranging these side reflectors in such a way that as the distance from the light increases the distance from the sides of the sign casing and the side reflectors decreases it will be seen that the strength of the rays at the farthest point will be greatly increased and as the dis Specification of Letters Patent.

tance is shortened in proportion to the increase of the distance from the light the strength of the rays at the farthest point will be equal to the strength of the rays at the nearest point to the source of illumination, therefore the light will be spread equally over the sides of the sign.

The sides or show faces B of sign case B are preferably provided with holes D receiving bulls eye lenses D. These we do not claim in such use except as combined with the reflectors in the especial arrangement described. Each face or side B may, however, consist of one sheet of glass having characters marked on it without affecting the operation of the other parts of the device hereinafter described or the scope of the claims apart from such special arrangement and adaptation.

The top-plate E has flanges is E, provided with bolt holes which correspond to holes 6 in the side walls of said casing. Bolts 6 passing through said holes fasten said flanges and top plate to the body of the casing.

The trough-reflector I suspended below the reflectors A A and capable of being lowered for inspection and other purposes consists of metal highly polished or enameled on the inside and is preferaby semi-hexagonal. in cross-section. It is provided with a hole H in the longitudinal middle line of its bottom. The supporting rod of said trough reflector is screw-threaded at its upper end 9 to screw into a screw threaded hole G in the plate or nut C, and is provided with a head G at its lower end, which head may pass through the hole H in the bottom of the trough reflector and be fastened outside the same, when in normal position, by the catch I, see Fig. 4:, which is pivotally fastened at 2' to the bottom of the trough reflector I and provided with a notch I adapted to engage the supporting rod G above the head G and thereby prevent the trough reflector from lowering to the position provided for easy access to the source of illumination (see Fig. 5) until said catch I is turned out of engagement with the supporting rod G.

T-irons or brackets F are fastened to the inside of the sides of the casing B. Their object is to act as a check to prevent the operator from inserting the trough reflector too far and to also hold brace rods K. To accomplish this last object they are formed of a sheet of metal of the correct width bent in the following manner; first a base flange 1 is formed, then a horizontal portion 2, then a vertical portion 3, then a horizontal portion 4, of the same height and parallel to the portion 2, is formed and then base flange 5 is formed. During this operation portions are punched or cut out of the portion 3, leaving holes 3. These T-irons are then fastened to the sides of the sign, care being taken to make the holes in the T-iron on one side correspond to the holes in the T- iron on the other side.

To the edges of the trough reflector I is fastened a check J consisting of two upwardly converging rods J J fixed at their upper ends to a ring J which is smaller in diameter than the diameter of the head G and encircles the rod G. The downward movement of the trough reflector is checked and limited by the said head which the said ring strikes against and remains against in the lowest position of the trough reflector. The T-irons F similarly limit upward movement of the trough reflector I, being struck by its upper edge or rim.

In the trough reflector is located and secured the source of illumination K, preferably an electric lamp but it may be anything that will give light.

The brace rods K are fitted at the ends into the holes 3 in the portion 3 of the T- irons F and serve to brace and hold apart the bottoms of the two sides B of the sign casing B. These are found particularly useful in large signs.

Various minor changes within the limits of the appended claims may be made in the construction and arrangement of parts hereinbefore described without affecting our invention.

e do not claim in this application a casing provided with two sets of reflectors, each of a trough shaped reflector and a pair of converging side reflectors, both sets sliding on the same series of rods as shown and claimed in our application #495,199; nor do we claim in this application a pair of straight integral converging reflectors hav ing a curved concave reflector below them as in our application #493,944.

We do not claim broadly in combination a sign casing, a reflector casting light through the same, a movable reflector normally within the said casing and reflecting light on the reflector first mentioned, a source of light and supporting rods for the movable reflector allowing the latter to lower out of the casing without separation from said rods, this subject matter though shown in the present application being sufliciently claimed in said application #498,944.
