OVERFLOW DEVICE FOR LAMPS.
SPECIFICATION forming part of Letters Patent No. 359,568, dated March 15, 1887.
i Application iled January 6, 1887. Serial No. 223,531. (No model.)
To all whom, it may concern,.-
Be it known that I, OTTO J. HEYNE, a citizen of the United States, residing at Springiield, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Overflow Devices for Lamps, of which the following isa specification.
This invention relates to lamps having an upper and a lower oil-reservoir, sometimes called pump-lamps,7 which contain means for lifting oil from the lower to the upper reservoir, and adjustable overflow devices to cause the oil which is delivered into the upper reservoir to be partially drawn back into the lower reservoir to a greater or less degree, as may be desirable, Vwhereby the number of hours that the lamp will burn, drawing its supply from the upper reservoir, is determined, the object ot' this invention being to provide improved overflow devices for lamps of this class, said devices being also applicable to any vessel containing iiuid for the purpose of drawing the contents of the vessel off down to a certain level.
In the drawings forming part of this specication, Figure l is a side elevation of a lamp having an upper and a lower reservoir, and a pump for transferring oil from the latter to the former reservoir, provided with adjustable overiow devices constructed according to my invention, the top of the chimney of the lamp being shown broken off. Fig. 2 is a plan View of detail parts of the device hereinafter fully described. Y
In the drawings7 A indicates the lamp, of which b is the lower portion or main reservoir thereof, which is ordinarily supplied with a considerably larger quantity of oil than is required to fill the upper oil-reservoir, c, from which the supply of oil for the burner d is directly drawn in the ordinary way, the said lower reservoir being filled with oil through a common tube covered by a screw-cap, e, said screw-cap being provided with a small venthole at x. A pump (shown in dotted lines in Fig. l) having a handle, n, projecting above the upper reservoir, c, is fixed in the interior of the lamp, as indicated, and is employed to pump the oil from the lower into the upper reservoir.
Lamps of this class are used principally for street-lamps, and the use thereof for this purpose demands that they should be provided with means which are simple and easily adjustable, whereby, after the reservoir c has been filled, or nearly so,with oil from the lower reservoir, such part of said oil as may be in excess of the quantity required to supply the burner of the lamp for a certain number of' hours shall be drawn off into the lower reservoir, so that there shall be no waste of oil; and it is also required in lamps of this class that said overflow devices shall be adjustable, to the end that sufficient oil for a greater or less supply of oil to the burner may be left in the upper reservoir to provide for the varying hours of burning the lamp.
' My improved adjustable overflow devices consist of a sip-hon, 5, the long leg of which ext-ends through the top of the lower reservoir, b, and through a collar, 6, secured thereon, as shown, the said leg of the siphon being screw-threaded, as shown, and has thereon a nut, 7,(shown in plan viewin Fig. 2,)the upper face of which nut has thereon certain graduating-marks and indicating -.numerals, for the purpose below described. A strap, 8,- is secured to the top of the reservoir b, and extends across the nut 7, and has a central perforation,through which the si phon 5 passes. The strap S serves to hold the nut 7 in the position shown in Eig. l, so that when the nut is turned to operate the overflow devices, as
below described, it will retain its proper position. The said strap S has a part of its edge at z properly formed to constitute a stoppingpoint for the nut 7, as below described. The said long leg of the siphon 5, when the latter occupies the position shown in Fig. l, extends nearly to the bottom of the lower reservoir, b, and the short leg thereof nearly to the bottom of the upper reservoir7 c, said short leg passing through a suitable opening in the top of the rlatter-named reservoir, and having a free movement therein. A tube, D, is fixed in the lower reservoir, b, as shown in Fig. l, which receives the long leg of the siphon, and aids in holding it in proper position. Said tube D is shown in dotted lines.
The operation of my improvements is as ICO follows: The lower reservoir, b, is supplied with a suitable quantity ot' oil through the tube, which is covered by the screw-cap e, and said cap is then screwed on. The Said pump is then operated by grasping the handle n, and oil is pumped from the lower into the upper reservoir in suitable quantity. With the said operation of the pump, and the consequent lowering of the oil in the lower reservoir, a certain amount of vacuum is created in the last-named reservoir between the oil and the upper side thereof, and, consequentlj/,as soon as oil enough has been carried into the upper reservoir, c, to cover the end of the short leg of the Siphon,said vacuum causes the oil in the upper reservoir to be drawn through the siphon down to the level of the end of said short leg, and therefore the position of said short leg of the siphon or the distance that the end thereof stands above the bottom of the upper reservoirdetermines the amount ofoil that will finally be left in the upper reservoir after operating the pump, as aforesaid.
rIhe figures l, li, l, li' on the face of the nut 7 indicate its position as shown bythe bar 8, which extends across it, when it shall have been turned to move the Siphon upward to bring the end of its short leg sufficiently above the bottom of the upper reservoir to leave oil in the latter sufficient to supply the lamp for respectively one, one and one-fourth, one and one-half, and one and three-fourths hours. Said gures on the nut 7 may be changed to other indications, as may be required, the extent of the rotation of the nut to adjust the siphon being of course dependent upon the fmeness or coarseness of the Screw on the siphon on which the nut works.
From the above description it will be seen that the overflow devices of the lamp consist of said siphon, having a connection with the upper and with the lower reservoirs, and a nut, by which the end ofthe leg of the Siphon which communicates with the upper reservoir is capable of being adjusted to such positions above the bottom of the last-named reservoir as will, after pumping oil into it, as aforesaid, draw off all of Said oil excepting a sufficient quantity to provide for burning the lamp for a given time, said nut being provided with suitable marks thereon, whereby the position of the short leg of the siphon in the upper reservoir is indicated for the above-mentioned purpose. The said Screw-cap c is provided with the slight vent x, which is only sufficient to permit of the proper action ot' the pump, and
is not suteient to interfere with the production of a proper vacuum by the action of the latter, whereby the oil, as aforesaid, is caused to be drawn by the siphon from the upper reservoir to the lower one, always leaving a certain quantity in the upper reservoir.
The siphon 5 may, if desired, be adjusted vertically, for the purpose aforesaid,by aid of the graduating-marks shown on its short leg, the dist-ance from lnark to mark signifying one hours supply of oil in reservoir c, the long leg of the siphon being made to fit sufficiently close in said tube in reservoir b to serve to retain the siphon by friction in any position to which it may be moved, thus making the siphon operativefor proper adjustment without the aid of a nut.
In moving the siphon each mark thereon is brought to view at the plane ot' the upper side of the top of the reservoir c, and thereby the height of the end of the short leg of the siphon above the bottom of said reservoir is indicated.
Vhat I claim as my invention is* 1. In combination, a lamp having an upper and a lower oil1eservoir, a pump to lift oil from the latter to the upper reservoir, and a siphon, substantially as described, having one leg communicating with the lower and one with the upper reservoir, and adjustable to bring the end of one of its legs to different positions above the bottoni of the upper reser Voir, substantially as set forth.
2. In combination, a lamp having au upper and a lower oil-reservoir, a pump to lift oil from the latter to the upper reservoir, a siphon, substantially as described, having one leg communicating with the lower and one with Said upper reservoir, and a nut, substantially as described, having a screwthread engagement with said siphon, whereby the latter is moved to adjust the end of one of its legs to different positions above the bottom of said upper reservoir, substantially as set forth.
3. The lamp A, having a lower and an upper reservoir, a pump, Substantially as described, to move oil lfrom said lower to the upper reservoir, the strap 8, secured on the lamp, a siphon, 5, having communication with both of said reservoirs, and the nut 7, having a screw engagement with Said siphon, cornbi ned and operating substantially as set forth.
