county of York, .England,ywool merchant,-

subjects of the King of Great Britain and Ireland, have invented new and useful Im-' provements' in and Relating to Lamps and Reflectors for Same, of which the-following" is a specification.

v This invention relates to improvements in lamps and reflectors for same, our object being to arrange and constructa lamp combined with lenses'and reflectors in such a manner as to utilize the light given off from the burner or the like to the fullest extent.

The purposes to which our device may be applied are naturally many and various, and while we hereinafter describe i same as being for use with a motor car or the like, we wish it to be understood that we do not limit ourselves to suchsingle application, the lamp and reflectors being readily adapted for signaling, for use with ships, trains or for other purposes. 7

Referring more particularly to motor cars and like vehicles, in many instances motorists or the like are satisfied to display only one side or head light and such arrangement is far from satisfactory, therefore we have turned our attention to the'arrangement and construction of a single lamp and reflectors for same so placed in connection with a motor car or the like as to show'three or more beams of light from one single electric bulb,

or. other suitable burner or source of illumination. It is well known that where one powerful light is used by itself, the glare is dazzling, yet a plurality ofequally powerful lights in the vicinity of the first light serve to mitigate the said dazzling effect while giving a better illuminating power. With a single burner and lamp we obtain prac-.

tically the same effect as a plurality of lamps, our lamp and reflectors being adapted-to provide from 3 to 5 or even more lights or seriesfof beams of light of to all intents and purposes, equal power. The lamp will be found to be of comparative lightness, and

economical to. produce when there is taken into consideration the resulting effect.

' In order that our invention may be clearly with reference to the accompanying sheets of drawings, similar letters indicating similar parts, in which Figure 1 represents a general view show- Fig. 2 represents a diagrammatic sectional invention, such plan may also represent a and 4: represent modified arrangements of reflectors hereinafter referred to. Fig. 5 represents a modified arrangement of reflectors and-lenses. Fig. 6 represents a detail of a swivel or adjustable reflector as hereinafter described. ,Fig. 7 represents a detail of lamp and mirror carrying means.

In carrying our invention into effect, for convenience of construction we prefer to construct the lamp A from a hollow sphere and arrange the burner or electric bulb B in the center thereof, an electric bulb being lene burners will necessitate the use of a chimney or openings for the escape of the will nothowever involve much difliculty of construction and may-be arranged in any suitable manner; the form hereinafter de scribed being one in which an electric bulb is employed.

Referring to Fig. 2 A is the sphere the circumference both as to sectional plan and sectional elevation being divided into six equal parts three of suchparts being cut out to form circular ports such as P, P and P the remaining parts being blank this arrangement as will be understood will give'5 ports one showing to the front, one at the top, one at the bottom and one to each side. Any one of these ports or all or a combination is opposite a blank. portion of the sphere such as R, R and R and such parts may -carry suit-able reflectors.

form the ports, to be utilized for reflectors on the blanks R, R and B the said cut away portions being burnished and plated or otherwise worked up into reflectors, these ing our invention as applied to a motor car.

The use of a. sphere of suitable metal to form the lamp from enables these portions cut away to;

and fully understood, we will describe same plan of a lamp constructed according to our preferred as the use of a gas, oil, or acetyproducts of combustion, such arrangementsthereof may be ,used as desired. Each port reflectors R R and B may be attached to the lamp and retained in position by means.

of adjusting screw nuts or the like S, which screw may assist in bringing the reflector into perfect focus with the bulb B ,each reflector having one of the said adjusting screws.

Each port be provided with a suitable glass arid mounted behind each glass is as shown in Fig. 2 a lens such lenses being designated by L, L and L Thus there will be 5 beams of equal intensity thrown in diflerent directions from the single lamp and bulb. This arrangement is shown in Fig. 1 wherein is shown the lamp A re- 'tained in a suitable bracket A projecting rays of'light in five directions. In order to collect the rays of light four mirrors or like reflecting devices M, M, M and M are employed, M being mounted say toward the top and center of the radiator or the like -M and M being placed at the sides and M below. All can be adjusted to the necessary angle to 'catch the-reflected light from the lamp. and again to,project same forward. If desired the mirrors may be mounted on the lamp bracket A or from arms attached to same or they may be carried on the lamp itself. It is preferred to support the lamp from a bracket or gateisuch as that shown in Fig. 1 and in more detail in Fig. 7 wherein the lamp A is carried on bracket A to which are attached two side brackets A one pivoted to one side of the vehicle and the other retained in position by a plunger or bolt A, One mirror M is mounted toward the top of the radiator, the mirrors M and M are carried from' the gate as shown and an extension A carries the mirror M below. To start the car the plunger A is lifted and the gate and lamp swung to one side, the gate being afterward placed back into the normal positionand fastened by the plunger A or other equivalent means. The lenses L, L, L are not of necessity arranged behind the port as shown. They may be combined with the'port glass or even be arranged in front thereof. a

The mirrors M, M M and M will require adjustment in order to obtain the correct focus and alinement of the light beams and this may be accomplished by mounting them in many ways one being shown in Fig. 6 wherein M is the mirror mounted on arm C carried by clamp C and held therein by set screws or like C to the clamp C is attached another clamp or like I) carried slidably on arm I) being retained in position by screw D The arm D is mounted on bracket H which is in turn suitably attached to the vehicle frame or the like. This arrangement allows complete adjustment and removal (when desired) of the mirror.

It will be understood that the mirrors are of. necessity set at an angle 'tothe vehicle and therefore they will not be so liable to become incrustcd with dust or dirt as *wduld through the port.

be the case were they to face the direction of travel direct as with ordinary lamp fronts.

When is is desired to increase the brilliance of one or more of the rays or beams of light, an auxiliary reflector B", Fig 3, may be employed placed in front of the -main reflector to concentrate the rays of light back on to the lamp and thereby assist its brilliance, such reflector being of practically the same curvature as the lamp casing.

In Fig. 4 is shown an arrangement adapted to utilize a portion of the reflector which would be dead when a lens L is employed which causes a spot on the reflector the same size as the lens on account of its not being in focus; this arrangement comprises a conical reflector F with its sides arranged to deflect such light on tothe outer surface of the reflector R which will then project the rays Fig. 5 shows a modified arrangement of reflectors and lenses which enables comparatively small mirrors to be used, where it is thought detrimental to have large beams of light projected rearward from the lamp. Condenser lenses L are placed in the desired ports and these condense the rays of light and same are in such state projected on to the small mirrors M In'order to project the light forward, in front of each mirror M is mounted a. lens L in focus with the intense spot of light on the mirror and the beams are magnified and straightened out and projected forward. The dia gram (Fig. 5) will serve either as a sectional plan or sectional elevation and is given to show an alternative only, as such arrangement will obviously not be so advantageous as that hercinbefore described with reference to Figs. 1 and 2.

The lamp port glasses or the like may be mounted in frames and hinged and retained in position in the usual manner, and the sphere may be divided into two readily attachable and detachable or hinged portions for cleaning and inspection purposes.

It will be understood that the hereinbefore described ports may be at angles to each other different to those shown in the drawings so long as such angles are other than 90 or 45 and which may be arranged to accomplish our object. More than five ports and their accompanying reflectors may be arranged without in any way departing from the principle of our invention. It will, of course, be understood that the interior surface of the lamp may be polished to serve as reflectors. Depending on the nature and disposition of the beams of light, the reflectors and mirrors may be either flat, concave or convex, and the same may be arranged at any desired angle in order to project parallel, diverging or converging beams of light.

What we claim as our invent-ion is: 1. In combination, a spherical lamp pro- I vided with a plurality of ports positioned in different horizontal planes and means .for

projecting the rays of light from each port in the same direction, certain of said means being externally positioned with respect to said lamp.

2. In combination, aspherical lamp provided with a plurality of ports positioned in different horizontal planes and reflecting surfaces operatively associated with each port foriprojecti-ng the rays of light in the same direction, certain of said reflecting ing-therethrough will be projected in a forward direction and means exterior t-o said lamp for projecting the rays of light from the others of said t-ion. v

4. In combination, a spherical lamp provided with three ports, reflecting surfaces therein positioned opposite each of said ports in a forward direcports and reflecting surfaces operative-1y associated. with cert-ain'of said ports and pov sitioned exteriorly of said lamp for projecting the rays of lightin the same d1rection. y

In witness whereof, we have hereunto set our hands, 1n the presence of two wltnesses.
