ACETYLENE LAMP Filed April 15, 1928 Patented June 11, 1929.
.BEN WILLIAMSON, or ASHLAND, KENTUCKY.
ACE'IYLENE LAMP.
. Application filed April 18, 1928. Serial No. 269,758.
The present invention relates to'improvements in acetylene lamps, and more pa rticu-,
larly to the dropper orva'lve controlled communication between the water and carbide containers.
"The principal object of the present inven tion is to provide certain improvements in the construction described and claimed in the U. S. Patent M. Stein, No. 1,376,651, dated lVlay 3d, 1921. i l
Briefly stated, the present invention aims to provide means for slidably keyin the valve stem to the screw threaded adjusting sleeve, in combination with means for longitudinally adjusting the valve stem relative to the dropper tubeand the adjusting sleeve, whereby to obtain an adjustment of the dropper valve relative toits seat or the lower end of the dropper tube, independent of the opening and closing movement of the valve by turning a of the adjusting sleeve, for setting the valve so as to properly function even though the same is worn by reason of continued use.
A further object is to provide for attachment of the operating handle for the adjusting sleeve to the latter in such manner that said handle will not break loose from'the.
for the valve stem, whereby positive down-' ward adjustment of the valve stem is insured uponv mere rotation of the ad usting nut,
' and whereby detachment and loss of the ad:
justing nut is prevented.
Otherobjects will appearas the nature of the invention is better understood, and the same consists in the novel form, combination and arrangement of parts hereinafter more fully described,shown in the 'acco 'npanying drawing and. claimed.
In the drawing Figure'l is a. view,partly in elevation and partly in vertical section, of an acetylene lamp constructed in accordance with thepresent invention Figure 2 isan enlarged fragmentary vertical section showing details of the dropper device;
Figure 3 is a horizontalsection on line 33 of Figure 2; I
Figure 4 is a horizontal section on line 44 of Figure 2; and
Figure 5 is an enlarged perspective view of '16 relative to the latter.
the operating handle for the adjusting sleeve and the attached nut for adjusting the valve opening 11 is provided in the top of the water container and furnished with acover 12.
Extending through the top and bottom of the water container is a. dropper which comprises an. open ended tube 13 having a hole communicating with the water chamber 4 in the usual way. The tube 13 is internally threaded as at 15 at its upper end, said tube being secured in place permanently by solder ing or the like at the top and bottom of the container.
Extended through the tube 13 and project ing at both ends therefrom is a stem 16 which is threaded at its upper end and provided ad jacent its upper end with a pair of swaged.
the stem 16 has its body flattened to form the wings '17 as clearly shown.
F ora'djusting the stem 16longitudinally or vertically relative to thetube 13 and sleeve 18, a nut 20 is provided which is threaded upon the stemlG and disposed upon the sleeve '18 to hold the keying devicesorwingsl? and slot 19 locked in adjusted relationship.
F or'convenience inrotating the sleeve 18 to raise and lower the stem-16, a handle 21 is provided which is permanently secured. to the sleeve and which is constructed of; resilient metal so as to operate as a tension'device to hold the sleeve against ready rotation, as
required to maintain and. establish. water flow. As shown, the nut 20 is provided with a reduced lower end portion which is attached and swiveled in an opening in the inner end of the handle 21 as generally indicated at 25, and a depending sleeve 26 is provided on the inner end of the handle 21 which is snugly fitted ell) over the head or upper end of the sleeve 18 and lirmly press 2d thereon against accidental upward removal. As the nut 20 is thus held. against upward movement when rotated to :uljust the stem 16 downwardly, downward adjustn'ient of thestein 16 is positively insured. The head. or upper end of the sleeve 18 is novided with a lateral projection 27, and, iormed in the inner side oi the sleeve 26 is a slot 28 through which the projection 27 extends. llhe n'ojection 27 is oi a width sidistantially corresponding to the width of the slot 28, and in this way. the handle 21 is keyed to the sleeve 18 so that the latter positively turned upon operation of the handle 21, as will be obvious. By reason of this construction, it is insured that the handle will remain operative for its intended purpose, thereby overcoming the objectionable tearing loose oi the handle from the stem as has heretofore been experienced when the handle is simply soldered upon the upper end of the sleeve as in the patent above mentioned.
To the lower end of the stem 16 there is secured a valve 22 provided with a. bottom flange 23 and with a cone 24.- which cooperates with the lower end oi? the (llOPpQl'tllllG 13 to control the How or dropping of water from the water container 4. to the carbide eontainer It will be obvious that upon rotation of the nuts 20 in one direction, the stem 16 will. be positively adjusted downwardly in case its removal, from the tube 13 is desired. Upon removal of the stem 16 the sleeve 18 may be readily threaded out of the tube 13 if necessary for purposes ol cleanin and repair. On the other hand, when the nut 20 is rotated in the opposite direction, the stem 16 n'iay be adjusted upwardly so as to set the cone 24: closer to the lower end of the tube 13 for a given adjustment of the sleeve 18, thereby adjusting or compensating for wear of the valve22 ailter continued use.
From the above description it will be seen that the stem slidably keyed to the sleeve 18 instead of being simply held engaged therewith. the nut 20 being used for material" and intentional adjustment of the stem 16 to adjust the valve 22 for compensating for wear. As the handle 21 is fixed to the sleeve 18 and the nut 20 is attached tothe handle 21, the downward adjustment or stem 16 is positively QlllQCl'GCl merely upon turning the nut 20, no downward :torce being necessary upon the rod 16' a i'ter turning the nut 20 as is required when the nut merely engages the upper face.
of the handle as shown in the patents men tioned above.
Minor changes may be made without departing from the spirit and scope of the invention as claimed.
hat I claim as new is 1. A dropper for acetylene lamps comprising a. tube open at both ends, a sleeve having a thread ed connection with the tube, a stem slidably extended through the tube and sleeve, a valve carried by the-stem, means for slidably keying the stem to the sleeve, a handle for rotating the sleeve, a nut for adjusting the stem longitudinally relative to the sleeve with their keying means relatively engaged, said sleeve having a head at its upper end, and a second sleeve on the inner end of the handle snugly fitted and pressed over the head of said threaded. sleeve.
2. A dropper :tor acetylene lamps com prising a tube open at both ends, a sleeve having a threaded connection with the tube, a stem slidably extended through the tube and sleeve, a valve carried by the stem, means for idably keying the stem to the sleeve, a handle for rotating the sleeve, a nut for adjusting the stem longitudinally relative to the sleeve with their keying means relatively engagfll, said sleeve having ahead at its upper end, and a second sleeve on the inner end oi? the handle snugly titted and pressed over the haul of said threaded sleeve, said head of the threaded sleeve having a lateral projection, said sleeve of the handle having a slot at its inner side snugly receiving said projection to key the handle to the threaded sleeve. i I
3. A dropper for acetylene lamps comprising a. tube open at both ends, a sleeve having a. threaded connection with the tube, a stem sl idably extended through the tube and sleeve, a valve carried. by the stem, means for slidably keying the stem to the sleeve, a. handle for rotating the sleeve, a nut for adjusting the stem longitudinally relative to the sleeve with their keying means relatively engaged, said sleeve having a. head at its upper en d, and a second sleeve on the inner end of the handle snugly fitted and pressed over the head of said threaded sleeve, said head of the threaded sleeve having a lateral projection, said sleeve of the handle having a slot at its inner side snugly receiving said projection to key the handle to the threaded sleeve, said nut being swiveled to the inner end of the handle. p
In testimony whereof I alibi my signature.
