UNITED STATES PATENT OFFICE.
`AMEDEE M. G. SEBILLOT, OF DENVER, COLORADO.
' ELECTRIC LAMP.
SPECIFICATION forming part of Letters Patent No. 253,770, dated February 14, 1882, Application filed November 1E, 1881. (No model.)
To allwhom it may concern:
Be it known that I, AMDE M. G. SBIL- LOT,ofDen\er,in the county of Arapahoe and State of Colorado, have invented anew and Improved Electric Lamp, of which the following is a full, clear, and exact description.
The object of my invention is to so com bine electric lamps with a reflector and an air-eX- hausterthatavacuum may becontinually maintained aboutthe carbons and the rays of light reiected in a proper direction, as hereinafter described. A series of these lamps are arranged within a parabolical or like annular mirror on the top of ahigh tower orlikestructure, which mirror throws the light-rays a great distance, whereby a large space can be illuminated.
Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters ot' reference indicate corresponding parts in all the figures.
Figure lis a longitudinal sectional elevation of the mirror and one of the lamps. Fig. 2 is alongitudinal sectional elevation of the combined air-pumps. Fig. 3 is a crosssectional elevation of the upper part of the light-tower.
The carbons A A' are contained within a glass globe,B,and are attached to the carbcn holders O O', attached to pistons D D', fitting in the cylinders E E', between which the globe B is held, the ends of the cylinders fitting so closely against the globe as to form air-tight joints. The carbo11holding rods O C' pass through the packing-strips F F', held by the packing nuts or boxes G' G' in the adjoining ends ofthe cylindersEE', through which packing-nutstherodsGC'alsopass. Threadedrods H H', provided with milled buttons I I' at the outer ends, pass into threaded apertures J J' in the pistons DD'. By turning these screwrods the pistons and the carbon-holders and carbons can be adjustedmthat is, they can be brought closer together or a greater distance apart. Thescrewsac' serve t0 lock thescrewrods H H', and consequentlyr also the pistons and carbon-holders, in the desired position. An air-channel, K, leads down through the wall or thickness of the cylinder E' to the tube L, leadL ing to the main tank or receiverM' of the com pound air-pump, which tube L is provided with a stopcock, b, to shut off the communication between the globe B and the tank M', from which the air is being continually pumped, so that when the globe B and the tank M' are in communication there will be a vacuum in the globe B, and this vacuum will be maintained as the pumps are to be operated continually.
The lamp is contained within a parabolic or like mirror, S, which throws someofthe lightrays down vertically,whereas others are thrown out a great distance, only slightlyinclined or al mosthorizontally. Alargemirror,S,isarranged in the form of a ring or overhanging circular cornice, S', on the top of a high tower or other very high building or structure, T, and a ring of lamps, constructed in the same manner as those described, is arranged within this mirror and below the overhang of the same, as Fig. 3 shows. As these lamps are veryheavy,Ihave provided a central derrick,R, for lifting them.
The globe Aof everylamp must be connected with the main tank M' ot' the compound airpump. This compound air-pump is composed of ascries of air-pumps, N' NZTN N4, and as many air-tanks, Ml M2 M3 M4, which regularlyT and gradually decrease in size, so that the tank in which there is the least pressure-that is, the tank TWP- will be the largest. The pumps decrease in size correspondingly, and are all connected with one and the same crankshaft, O; but the cranks vary in size with the pumps. The cylinder of each pump is connected with the two tanks, betweenwhich it is located", by pipes P P.
The outlet-valvesQof the tanks open downward or outward and the inlet-valves Q' open inward or upward. I do not limit myself to any number ot' air-pumps and tanks in the compound air-pump; nor do I limit myself to any certain or specified arrangement in the size of the tanks and pumps. Likewise the number of lights arranged under or within the annular mirror S on the top of t-he tower or structure Tmay be limited, and the size and form ofthe annular mirror may be varied. This mirror is so constructed as to send the most powerfullyreflected rays at the circumference, as shown in Fig. 3.
The pumps N' to N4 are so constructed that the pressure of the air in the tank M4 will be one- Itenth ofan atmosphere, the pressure of the air in the tank Mf'one one-hundredth of an atmos roo phere, in the tank M2 one onc-thousandth of an atmosphere, and in the tank M one ten-tl1ou sandth of an atmosphere. The pressurein the globes B,Wl1icliare all connected with the tank M', will also be one ten-thousandth of an atmosphere only. rlhis reduction of the pressure could not be maintained with a single pump, as the backpressure of the air (which has one atmosphere ofpressure) would not permit ofsuch reduction; but by the first pump, N, the pressure is only reduced to one-tenth ofan atmosphere, and the back-pressure on the second pump, N3, (which rareties the air to one onehundredth of an atmosphere,) will only bconetenth of an atmosphere, and in the same manner the back-pressure on the pump Nzwill only be one one-hundredth of an atmosphere, and tliatof the pump N will only be one one-thousandth of an atmosphere-that is, the air is successively pumped from the globes Binto the tanks M M2 M3 M4,and its pressure gradually increases toward the first pump, N4. The carbon-holders C C are connected with the poles of an electric generator of any suitable kind.
These lamps may also be used in private 25 dwellings independently7 of the pumps, by
which, however, the Vacuum is created in the globes, which are then sealed, and then arranged at the desired locality. l
Having thus fully described my invention, 1 3o claim as new and desire to secure by Letters Patent- The combination, with a reflector and airexhauster, substantially as described, of a ring of electric lamps having opposite adjustable 35 carbons surrounded. by a transparent vessel connected with the air-exhauster, whereby the vacuum may be maintained and the rays of light reflected, as described.
