SPECIFICATION forming part of Letters Patent No. 303,844, dated August 19, 1884i.
Application filed August 4, 1888. (No model.)
iro ctZZ 1.072.072?, it iii/(by concern.'
Be it known that I, MICHAEL C. HARNEY, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented an Improvement in \i.cl;-Raisers, of which the following is aJ specification.
My invention relates to those wick-raising devices in which a vertical shaft, a horizontal shaft, and contrate or crown wheels connecting the shafts are employed to adjust the wiel: from beneath the fonnt or reservoir, the vertical shaft being secured to the outside of the fount or reservoir, its lower end being passed down through the base, and provided with a wheel, by which it may be turned.
My improvement consists in certain details ot' construction, hereinafter described, and pointed out in the claims, whereby the means for operating the wick-shaft teud'to hold the latter to its bearings, thus preventing the displacement of the burner cone or cap by the elevation of the wick-shaft, as in previous devices where the means for turning the wiel;- shaft are located beneath or on one side ofthe latter.
rihc accompanying drawing is a pcrspeo tive view of a lantern having my wick-raising device, a portion of the body of the lantern being removed to exhibit the application of the device.
A is the base; I3, the body; the fount or reservoir; l), the burner without the cap or cone; lil, the wiclvshaft having contrate or crown wheel Il, G', the vertical shalt having contrate or crown wheel II, located over the wick-shaft crown-wheel, I, strap for securing the body of the vertical shaft to the reservoir; J, the air-chamber between the body and the fount, having a Iloor, K, provided with opening for passage ot' the vertical shaft; and L, a loclenut beneath the iloor to hold the teeth ol" the crown-wheel II down to engage the teeth of the erowirwheel F, when adjusted on t-he threaded end ot' the vertical shaft, which earries the.regulatingwhcel M.
By the arrangement ot' the various parts as shown there is not any liability of the dis placement ol' the wiclt'shaft, burner, or cap orv cone, because the nut beneath the floor can be adjusted on the vertical shaft, and the latter with its crown -wheel to a nicety to sufficiently engage the crownwheels without displacing the wick-shaft.
I am aware that crown wheels have been employed to connect the vertical and horizontal shafts. Also,.that a nut has been einployed, by which the vertical rod of a wickraising device could be adjusted. Also, that the vertical shaft has been strapped to the outside of the fonnt, and its lower end passed down through the iloor of the lantern, where it has been provided with a hand-wheel. Such construction, therefore, I disclaim as used and applied separately. The advantage of my ar rangement will be seen to be in so adapiing the various partsI as to permit them, when combined in the manner shown in my device, to provide means by which the horizontal crown-wheel can be adjusted to the vertical crown-wheel. by simply adjusting the nut on the thread-of the vertical shall beneath the licor.
Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:
l. The combination, with a l'ount having a burner provided with a wick-shaft having a crown-wheehof a vertical shalt having a crown-wheel at its upper end over the wichV` shaft erown-wheel, and a screw-thrcad at its lower end provided with a locl -nut, and a regulating wheel, as set forth.
2. The combination, with a fount, a burner provided with a \vielc-slmi`t, and a crownwheel on the wiel; shaft, ol' a vertical shaft having a crown-\\'heel at its upper end above the crown-wheel ot' the wicltshal't, and screwthreaded at its lower end, a lock-nut on the sorew-thre'zul to adjustthc vertical shaft, a regulating-wheel, and a lanterirbody having an opening in its 'loor, through which the vertical shalt extends, as set forth.
