ROY BODNEY WILEY, WALLACE KENNETH XVILEY. AND WILLIAM SIMPSON ROUGH,

JR.. OF ST. CATHERINES. ONTARIO, CANADA.

LLUMINATED SIGN.

To all whom lit 1muy concern:

ll'armcr; K. WILEY. and lYiLLLm S. Horen, Jr., citizens of the United States of America, and residents of St. Catherines, in the Province of Ontario and Doniinion of Canada, have invented certain new and usefnl Improvements in Illuminated Signs, of which the following is a specification.

Our ini ention relates t.) signs in general, and to illuminated signs in particular.

The objects of the invention Aare to produce a maximum brilliancy, with a minimum number of lamps; to protect'the reflecting surfaces from dirt. and the weather; to eliminate all useless portions of the retlectin surfaces, for the purpose of reducing bu 'and weight; to eradicate blurring effects i and localized bright' spots, and to provide a durable sign for loi-.g distance vision, aswell as for short range.

Thestatenient of the invention is as follows, it being noted that. the various scopes of the invention are attended to in the claims hereinafter annexed.

The organization, underlyingr our conception, ponsists of a plurality of cent-ral segments of parabolic reilectors placed relatively to each other so as to form a character,

the arrow Y.

a box whose contour is that of said character,

surrounding said reflectors, a glass plate covering said box, and lamps for the rellectors.

Figure 1 is a front elevation of'the device.

a portion of a modified reflector, on anen' larged scale. Fig. 4 1s a front elevatloh of a modifiedA construction of the letter Fig. 5, is a side View of that portion of the letter N, at the left of the line W' Z. F1g. 6 is a front elevation of the frame used 1n eferring particularly to Figs. l and 2,

the structure consists of a. box, shaped like mental parabolic reflectors 3, grouped to form the letter H, and located inside of said 'box l, the redecting portion of the reflector being tfnatportion of a paraboloid, which lies between two parallel planes, respeo,

Fig. 2 isa vertical section at the line i X X, in Fig. l, looking in the direction of Fig. 3 is a side elevation of Specification of Letters Patent.

tively on opposite sides of the axis of the Be it known that we, Roi R. lVILErM e respectively located at the foci of the reflecln operation` the light is divided, one portion being reflected by cach reector S, in a beam of light having' approximately a rectangular shaped cross section, another por` tion being thrown forward by the fiat surface 9, at the back of the lamp, and another portion striking the reflector 5, then the reff ectors 9 and 8,`and finally leaving the device, while .some of the light radiated to the reflector 5, passes through the holes thereof,

and evens up` the. general brilliancy of the character.

Our invention may be modified Without departing from the spirit thereof. Instead of tte more connnon parabolic surface of spoon shape= the surface 8a maybe that described by a parabolic curve moved parallel to a plane which coincides with the axis of the parabola, and farther and farther away from said plane, Fig. 3; being anA enlarged side View o a portion of such a parabolic surface, and Fi s. 4, 5 and 6 being di'erent views o connote parabolic surfaces applied in a modified construction. The said modified construction embodies the l mission of 2class fronts and casings for the reectors.

le will now' describe the modiiications shown in Figs. 4, 5, and (3.v series of retlectors A., B, C, &c., -are mounted end to end on an N shaped frame, composedo long and narrow boxes G, which contain the Wiring H' for the lamps H. I represents cross braces for making the structure suitable for shipping and for endurance. J 100 represents bolts and nuts for attaching the letter N tol supports usually on the tops or sides of`buildings.

By this simple construction, it, is easy to provide signs several feetv high, and by 105 means of only one lamp in each reflector, i

the sign appears brilliant all over its surface, and at great distances away.
