United States Patent O atenas? LAM? BEVER Wilbur i2. Wade, M572 Mill St., Portland, Greg. Filed ee. lS, wel, Ser. No. 16ml@ 1 Claim. ("Ql. 40m-77) This invention relates to a type of lamp device, and more particularly to a novel lamp device that includes adjustable mechanism for dispensing information. In a particular embodiment of the invention, a lamp device is contemplated that may be used by piano and organ players, and the like. Information dispensed by the adjustable mechanism may then relate to chord structure, and serve as an aid to the player as he performs.

A general object of the invention, therefore, is to provide a novel type of lamp device, that includes novel adjustable mechanism for dispensing information.

A related object is to provide such a device, with an information dispensing mechanism constructed in a novel manner whereby part of the light emitted from the usual lamp bulb in the device is used to illuminate an indicator body in the mechanism having marked thereon the information to be dispensed. Thus, the indicator body may be read easily in darkened rooms. j

A further object is to provide a lamp device, with illuminated mechanism for dispensing information, where the mechanism is constructed so as fully'to utilize available light.

Related objects are to provide a lamp device of the above general description that is easy to manipulate in order to obtain the information desired therefrom; a lamp device that is readily adjusted to a position where direct light is shielded trom the person using thelamp device; and a lamp device that is simply and economically constructed, and thus producable at relatively low unit cost. These and other objects and advantages are attained by the invention, and tie same is described hereinbelow in conjunction with the accompanying drawings, wherein:

HG. l is a side elevation of a lamp device constructed according to one embodiment of this invention, and with portions of the device broken away to illustrate details ot interior construction;y

HG. 2 is a front elevation of portions of the lamp device illustrated in FIG. l

FG. 3 is a cross-sectional view, on a somewhat enlarged scale and taken generally along the line 3-3 in FIG. l., illustrating details or" an indicator body that is part of adjustable information dispensing mechanism in the lamp device; and

FiG. 4 illustrates, also on a somewhat enlarged scale, portions of a cylindrical shade in the device and howinformation may be read in viewing the indicator body through apertures provided in the shade.

Referring now to the drawings, and lirst of all in particular to FlGS. l and 2, the lamp device shown comprises generally an upright standard or support, indicatedat l0, having an upper portieri 19a bent over at an angle, and a substantially vertical lower portion lllb. Abase l2 is provided at the bottom end of lower portion llilb, and such serves as a support for the lamp device as a whole. Mounted on the other end of standard is hood structure indicated `generally at 1d.

interconnecting base l2 and standard l@ is a socket assembly i6 pivotally connected at id to base l2 so as to accommodate swinging of the standard about a horizontal axis, and thus swinging of the standard to various inclined positions. The base of the standard is rotatable within assembly i6 about a vertical axis in FG. l. Such movement allorded the base of the standard "ice accommodates positioning of hood structure lliin various positions to the front, rear, and sides of base l2.

Hood structure 14 is connected to the dispositey end of the standard through a socket assembly 2e similar to socket assembly 16 just discussed. Thus, at 22 there is indicated a pivot connection pivotally connecting structure ltd to standard lll with structure i4 swingable about a horizontal axis in FIG. l. tructure le is rotatable relative to the top end of standard 1l) about an axis extending longitudinally o portion 10u. Thek connection of hood structure lll with standard l@ is such as to enable the hood structure to be tilted over at either end, or swung up and down.

Considering now the construction of hood structure 14, and referring now to FlGS. l, 2, and 3, structure 14 comprises an elongated and substantially cylindrical shade element 24 connected midway between its ends to socket assembly 2d through lug Z5. ln the embodiment illustrated, each end ot shade member Zdis closed oli by a cup member secured in a suitable manner to the shade member, such as cup or closure member Z6 closing oil the lett end of the shade element in llG. 3. Shade element 24 has a bounding edge Ella, and extends from this edge over approximately a 270 angle to another edge 24h. Edges 24a, Zeb define an elongated opening extending along one side of the shade element, and the shade element extends substantially without interruption between edges 24a, 24h over the other side of the shade element.

An adjustable information dispensing mechanism in the lamp device comprises a rotatable indicator body or cylinder Si), journaled within the hood structure adjacent one end thereof. The indicator cylinder is rotatable about its longitudinal axis, and such axis coincides with the longitudinal axis of shade element 24.

In the embodiment illustrated, the indicator cylinder comprises end members or spiders 32, 33, spaced along the length of the indicator cylinder, and secured to the ends of a shaft 34. Spider 32 at the right end of the indicator cylinder in FIG. 3 is secured directly to shaft 34 by a screw 36. Spider 33 at the left end of the indicator cylinder in FIG. 3 has a cover cap 3S joined thereto, and a nut il and screw rtf; secure the cover cap and spider together with a washer i4 thereinbetvvcen. The cover cap and spider 3.3 are secured to shaft 3ft by screwing screw 42 into an accommodating threaded bore in the end of shaft 3st. At 46 there is indicated a lock washer that holds nut lh securely with the cover cap and spider 33 joined as one. Felt rings are indicated at d?.

Spiders 32, 33 have annular flange portions 4d that ex tend toward each other from opposite ends of the indicator cylinder. Fitted on the inside of these iianges and seated in grooves 5t) is a section of material 52 that is pervious to light. Such section ordinarily might take the form of a light-colored, translucent plastic sheet. Informative markings are prepared on the surface of section 52. A portion of section 52 is shown in FIG. 4, and such markings are indicated at S4.

Mounted within hood structure 1d adjacent the end opposite indicator cylinder E@ is a lamp socket means 5o, of conventional construction, for mounting alamp bulb 5S. A conductor 65 supplies electric current to socket means 55. Over the end of shade element 24 is a .cover cap et), that snugly encircles the outside of cup .'26 closing oil the end of the shade element. Lamp socket means 56 is secured in place by a nut 62 screwed onto an externally threaded portion o4 that is part of the lamp socket means and that extends through cup 26 and cap di?. Switch knob 65 is for turning the lamp on and od. Lamp bulb 555 within the hood structure is exposed by the opening defined by edges 2da, 24h, and with the bulb energized, light shines out through this opening.

Spiders 32, 33 have apertures 68 therein that open to the interior of the indicator cylinder or body. For this reason, the interior of the indicator cylinder is lighted by light emitted from a lamp bulb in socket means 56. Light inside the indicator body shines through light-pervious section 52 thus to illuminate the informative markings on the section during use ofthe lamp device.

1t should be noted that the opening along one side of the hood structure dened by edges 24a, 24h extends the entire length of the hood structure, and that a portion of light-pervious section 52 is exposed by the opening. Light shining through section SZ passes through the opening where the section is exposed. Thus, with a lamp bulb lighted, light is given ort along the entire length of hood structure 1d.

Apertures 7b are provided in shade element 24, and these are spaced away from edge 24h, in a direction extending from this edge around the sides of the shade element opposite the side containing the opening, to edge 24h. Three of such apertures are indicated, although various other numbers could be provided, if desired. n rotation of the indicator cylinder, selected ones of the informative markings on section 52 come into registry with the apertures, thus to become discernible to a person looking at the outside of shade element Z4.

in a typical case, the lamp device may be intended to aid a piano or organ player, and the adjustable mechanism described used to dispense information relating to chord structure. Thus, as can be seen in FIG. 4, under the upper left aperture 70 labeled CHORD NAME there appears a letter C (marked on section SZ) which designates a specific key. To the right of this aperture, is an aperture which is labeled CHORDS MOST COMMON- LY USE-D 1N THiS KEY. Here letters EZ A7, 137, GZ 12, and Fm appear. These indicate chords that are commonly used in the key of C. The lower aperture may be used to indicate other chords used in the key of C, with certain musical effects produced. On rotation of the indicator cylinder, similar information in connection with other keys may be made to appear through the apertures 70.

In using the lamp device, the cover cap 38 at the left end of the hood structure constitutes a turn means er1- abling turning of the indicator cylinder within the hood structure. Adjustment of the indicator cylinder is easily made by holding structure 14 adjacent its other end with one hand, and with the other hand turning cover cap 3S.

Thus, an adjustment may be made, Without touching cenr tral parts of structure 14, where one might be subjected to becoming burned. l

Summarizing some of the novel features of the invention, light from the lamp bulb shines into the indicator cylinder from one end, and is used to light its interior and thus make markings on section 52 observable. Apertures 70 are located on a portion of the shade that may be viewed with the viewers eyes shielded from direct light from the lamp bulb. Light shines through the opening in hood structure 1d along the entire length of the opening. Pivotal movement in the lamp standard accommodates positioning of the hood structure easily to a position where apertures 70 are visible and the lamp bulb within the hood structure is shielded.
