NEBULlZER AND MEANS FOR ATIACHING SAME ,TO SUPPORTING-TANKS.

SPECIFICATION forming part of Letters Patent No. 745,415, dated December 1, 1903.

I Application filed August 19, 1903. Serial No. 169,981. (No medeld To all whom it may concern: I

Be it known that We,WILLIAM BOEKEL and JULIUS BOEKEL,citiZenS of the United States, residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania,have invented certain new and useful Improvements in Nebnlizers and Means for Attaching the Same to Supporting-Tanks; and We do hereby declare the following to be a full, clear, and exact description of the invention, such as Will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to nebulizers and means for attaching the same to a supporting-tank, and has for its object to allow the nebulizer bulb or bulbs, with the parts contained therein, to be turned axially into horizontal, vertical, or any intermediate inclined position, while securing the maximum of strength, cheapness, compactness, and simplicity. To this end the said invention consists in the construction and combination of parts hereinafter more particularly set forth and claimed.

In the accompanyingdrawings, Figure 1 represents a side elevation of a single-bulb nebulizer embodying our invention, only the part of the tank and inclosed parts being shown. Fig. 2 represents, on a larger scale, a vertical central section of the nebulizerbulb and its supporting devices, the spraytube being shown in elevation. Fig. 3 represents a vertical longitudinal detail section of the spray-tube on a still larger scale, the upper end being broken away; and Fig. 4 represents a detail perspective enlarged view of the bulb-cap and devices for attaching the same to the tank. Fig. 5 represents a detail vertical section of the spray-tube enlarged.

A designates the upright air-tank, having tubular outlet at projecting from its side near the upper end and screw-threaded for the attachment of a doubly-screW-threaded nebulizer-coupling D. There will of course be as many of these outlets as there are nebulizerbulbs. For many uses one willsuffice. B designates the barrel or cylinder of an air-pump arranged within the said tank and having an operative reciprocating piston-rod G. The mechanical and pneumatic connections between the said tank and cylinder at their lower ends are not shown, being quite irrelevant to the present invention L designates an L-shaped nebulizer-sus pending bar the horizontal arm of which is provided with a reduced neck Z, adapted to enter the bore a of outlet at, and also with the screw-threads Z for engagement with the outer series of internal screw-threads of the said coupling. The short arm Z of the said bar L has a spray-tube M attached to it, preferably by soldering, though these parts may be screwed together or secured in any other convenient manner. The bulb N, inclosing this spray-tube, has a screw-threaded neck n, as usual, wherebyit is connected to the screwthreaded lower part 0 of a cap 0, the upper part of which forms a hollow drum O inclosing a space surrounding the upper end of the said'spray-tube and having a lateral outletopening 0 to receive the nipple p of a hose P, extending to the inhaling-mask Q. The

said cap is rigidly attached, either permanently or detachably, to the short arm Z of the tubular suspending-bar L and also the long horizontal arm of the said'tubular bar by a brace-bar R, preferably of T form in cross-section, which may be cast with said tubular bar. A plug S, suspended from said bar by a chain T, may be inserted in outletopening, 0 when the bulb and spray-tube are not in use. The said spray-tube may be in any of the well-known forms covered by our previous patents. We do not claim it in the present application. It has, preferably, as shown, an upper section provided with a central air-passage U and side outlet-passages u therefrom, a lower section V, having a liquid passage V extending up from its lower end and continued up through a reduced part '0', which screws up into the said upper section, leaving an annular airspace between them for the side air-passages u to connect with, and a ring or annular third section W, fitting on a reduced upper part of the end of the lower section, so as to leave an annular liquid-space w, connected to liquidpassages Vby side passages 11. The proximate edges of section U and ring W form at one point a narrow spray-hole X, receiving air and liquid through the passages and annular spaces aforesaid, so that the air driven by the said piston through outlet a, tubular suspending-bar D, and section U will issue through said spray-hole and draw up the liquid through the section V, driving it out also through the said spray-hole in a Very fine nebula or spray. It then fills the upper part of the said bulb, enters the drum at the top thereof, and passes out through the hose to the inhaling-mask.

By loosening the coupling aforesaid the op erator is permitted to turn the bulb and contents from a horizontal to a vertical position or the reverse, and then by tightening the coupling he may look the bulb securely in either or any intermediate inclined position without interrupting the flow or lessening the efficiency of the apparatus. This is often convenient in practical use,enabling the mask audits flexible tube to be more conveniently directed to and applied at the point where needed.

The tank may of course be arranged horizontally instead of vertically, in which case the words horizontal and vertical applied to the bulb and attachments would of course require to be reversed; but no change of structure would be necessary.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. A nebulizer-bulb and spray-tube,in combination with a tank which supports the said parts and connections which permit the said bulb and spray-tube to be turned into a vertical, horizontal or inclined position at will with respect to said tank, their operation being unaffected thereby, substantially as set forth.

2. The combination of a tubular suspending-bar having a reduced neck with a tank having an outlet receiving the said neck, a tubular coupling connecting the said bar to the said out-let, anebulizer-bulb cap attached to the said bar and suspended therefrom, a brace-bar connecting the said cap and the said tubular bar and a bulb and spray-tube arranged and operated substantially as set forth.

3. The combination of an angular tubular suspending-bar with a tank having an outlet communicating with the bore of said bar, a coupling which permits the axial adjustment 'of the said bar and a nebulizer-bulb and spray-tube attached to the bent outer end of the said bar in order that such adjustment may vary the position of the said bulb and tube substantially as set forth.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.

WM. BOEKEL. JULIUS BOEKEL.
