RI-DE,
Application filed Jury 2,
To all whom it may concern: Be it known that I, JAMES M. MONT- ooMERY,'a citizen of the United States, residing at 'Ber'y, in the county of Mineral and State of West Virginia, have invented certain new and useful Improvements in Carbide Lamps; and I do declare the following to be a full, clear, and exact description of the invention; such as will enable others skilled in the art to whichit appertains to make, and use the same, 5 K
My invention relates to' improvements in carbide lamps, such as those used by miners, the principal object of the invention being to provide a simple and inexpensive agitator Within the carbide receptacle but having an operating handle exposed at the bottom of such receptacle, said agitator serving not only to revive the charge of carbide without the addition of more water but being operable also to effectively loosen the exhausted carbide to permit easy dumping thereof, without the necessity of pounding the receptacle, with danger of opening leaks therein.
The carbide receptacle has a threaded connection with the remainder of the lamp and it is a further object of the invention to provide a handle for the agitator which is of such sha e that said handle can be turned only in a irection which tends to tighten the threaded connection, as otherwise there would be danger of loosening this connection and wasting gas when operating the agitator.
With the foregoing in View, the invention resides in the novel subject matter hereinafter described and claimed, the description being supplemented by the accompanying drawings.
Figure 1 is a side elevation partly in section showing a lamp equipped with my improvements.
Figure 2 is a vertical sectional view of the carbide receptacle and the agitating means associated therewith.
Figure 3 is a horizontal sectional view on line 3-3 of Fig. 1.
Figure 4 is a bottom plan view.
Figure 5 is a detail vertical section on line 55 of Fig. 4.
In the drawings above briefly described, the numeral 1 designates a carbide lamp of the type used by miners, said lamp having a water receptacle 2, a carbide receptacle 3 an. serial no. wjua:
beloWthe-water receptacle, a threaded connection t between the two receptacles, 'and a valve 5 for controlling the discharge" of waterfroni' the receptacle 2 into thecarbide receptacle 3.
Within the receptacle 3, 1 provide an agitator 6 which is preferably 'of' the U- shaped form shown 'inFig.'2,to loosen the carbide around'the 'fside wall and' 'adjace'nt the bottom of said receptacle' This agitater is carried by a 'central'dependingstub '7 which passes rotatably through an opening 8 in the bottom 9 of the receptacle 3, a packing washer 10 being interposed between the agitator and bottom, while another packing washer 12 is preferably disposed against the lower side of said bottom. I have shown a washer 13 hearing against the packing washer l2 and formed of metal or other rigid material and a clamping nut 14 is threaded on the stub 7 to contact with said washer 13. It will be seen that by tightening the nut 14, the two packing washers 10 and 12 will be tightly held in place to prevent possible leakage around the stub 7 The lower end of the stub 7 is provided with an operating handle which is preferably formed from a single strip 15 of metal or other desired rigid material, the center of said strip having an opening in which the stub 7 is secured, for instance by a nut 16. The end portions of the strip 15 are curved upwardly into close proximity with the bottom 9 of the receptacle 3 and said ends are then bent downwardly to provide a pair of finger-grips 17 to be engaged by the thumb and forefinger in rotating the stub 7 and the agitator 6. To prevent rotation of these parts in a direction which would tend to loosen either the connection of the handle with the stub 7 or the threaded connection 4, I provide the grips 17 with oblique or inclined lower edges 18 extending throu hout their horizontal width, said beveled e ges having their upper ends in a plane above the lower edge of a depending rim 19 with which the bottom 9 is provided. The lower ends of the inclined edges how ever are of considerable distance below this rim and are connected with the body portion of the strip 15 by vertical edges 20. A. sufficient thrust may be exerted against the edges 20 to readily turn the agitator and associated parts in the desired direction, but the users thumb and fingers will slip from iii n" fleb "ilfifi 'tfibffi made to tliri i liie fig ftor in a r vr so direction. Thus, there is no danger of loosening the threaded eenaeetien 4 or er pesibiy wages mg the connection between the brindle strip 15 and the stub 7. v 7
