PIANO-LAMP.
Specification of Letters Patent.
Patented Mar. 1 4, i591 1 Application filed March 1, 1910. Serial No. 546,673.
To all whom it may concern:
lie it known that I, Janus (l. Mwctisxznc, a citizen of Canada, residing at Westville, Pictau and Province of Nova Scotia, Canada, have invented new and useful Improvements in Pi-ano-Iaunps, of which the following is a specification.
This in ention relates to a lamp designed niore'especially as an attachment for pianos and organs so as to concentrate the rays of light wholly on the music andprevent an annoying glare in. the eyes of the. musician. The. invention has for one of its objects to provide a cou'iparatirely simple, ine'vpele sire and ellicient' device of this character which is of attractive. appearance and can be used as a permanent part oh'or as an attaelnnent for, the music instrument.
;\1l()tll l object of. the'invention-is the provision of a lamp in the nature of a tubular shield or holder ha ring a longittuli-- nal slot through which the rays from the incandescent lamp bulbs are directed on the music. there being a door that swings upwardlyand baclnvardly to open position for emitting; rays forwardly whenever desired, the holder or tube being construction and more or less ornamental.
\"v'ith these objects in view, and others as on appear as the description proceeds. the invention comprises the various novel t'eatures of construction and arrangrenumt. of
parts which will be more fully described hereinafter and set .t'orth with particularity in the claims appended hereto.
in the accompanying drawings, which illustrate one embodin'lent .l inure is a front view of a device partially broken away; and Fig. 2 is an end view thereof with the lamp tube or holder in section.
Similar reference characters are en'lp'loyed to designate 'corrcs ionding parts through the several views.
Referring to the drawing, A designates the tubular holder or guard of the device. the same being disposed horizontally and supported on brackets 1 which may he attached directly to the lIlSllUlIlQIll by the manul'ahturer or when the device is used as an atta'el'uuent. the brackets may be secured to starularrls 2. which -will rest on the music holder ol the instrument. The. tube. A,
which may be constrmatt-al of sheet metal."
\vrmilm' other suitable material and finished in any desired rrnmner and posscsslng an of any approved of the nvention;
! ornai'nental form, is closed at: its ends by caps 3. and immediately adjacent thecaps, the tube is corrugated at 4, to provide a stronger hold for the cement or plaster of Paris it, which secures the incandescent lamp sockets 5 in the ends of the tubular holder or guard. In those sockets are screwed bulbs '(iiwhich illuminate the music. there being a. lon itua b tonal slot at the bottom of the tubular holder through which the rays of light are directed on-the music in a manner shown in Fig. 2. The body A is preft'eri-ibly lined with asbestos S or equivalent material whieh being white serves as a light diffuser .and also prevents excessive heating of the body A. The body A has its front. open directly at the bulbs so as to provide access thereto for rcinovaland renewal, and also for permitting the rays of light to be directed for- I wardly whenever desired. These openings are. normally closed by'doors S), which are approximately scmi-cylindrical in form to correspond with the shape of the tubular body A and the hinges 10 are located to the rear of a vertical line passing throughthe tubular body so that when a door is thrown open, it will-remain by its own weight in such position, asshown by dotted lines in Fig}: 2. The bulbs are connected to wires 11, which lead in through the brackets it from thestandards 2, which may be hollow to -receiv the wires and the wires are connected in suitable manner with a source of supply. When the lamp is applied. to a piano or organ by the manufacturer, the.
wires can be concealed within the case of the instrun'leut', or when the device is to be rigidly fastened to an instrument already in use. the connecting wires can be cov' nil by a strip of the same color as the casin at I the Instrument. device of this character is extremely useful for the purpose intended and is of such design as not to detract. from the. appearance of the instrument to' which it is applied.
- From thev foregoing description taltenin connection with the accompanyin drawing. the advantages of the construction and of the method of operation willbe. readily apparent to those skilled in the art to which the. invention relates. and while 1 have dc l l scribed the principle of operationoli-the inj vention, together with the device which I I thereof. I desire to have it understood that. l the apparatus shown m merely illustrative now consider tov be the best: enlhodimcnt; 110' and that such changes may be made when desired as are within the scope of the claims.
What I claim as new and desire to secure by Letters-l-ate11t 1s:----
1. A devlce of the class described, comprising a horizontally disymsed tultmlmbody prising a tubular body havin spaced openings in its front and proviC ed with light emitting means in its bottonn a pl urality of lamps mounted in the body and arranged one at each opening, cove's separately mounte on the body and adapted to swing u nvardly and rearwardly to open position, and means for connecting the lamps in circuit. with a source of current.
In testimony whereof I aflix my signature 3;,
in presence of two witnesses.
