JACOB IGNOT ROBIN, OF LONDON, ENGLAND, ASSIGNOR TO STRAND MAN-TITLE AND MACHINE COMPANY, LIMITED, OF LONDON, ENGLAND.

ADAPTER FOR BUNSE-N BURNER/S.

Application filed June 4, 1913.

To alt 107mm it may concern Be it known that I, JACOB IGNOT ROBIN, a citizen of the United States Republic, and residing at 111 to 113 Great Titchfield street, London, WV, England, have invented certain new and useful Improvements in or Relating to Adapters for Bunsen Burners, of which the following is a specification.

This invention relates to adapters for Bunsen burners and has for its object to devise means for overcoming the diificulties that have hitherto been incidental to all attempts to increase the efiect of a Bunsen burner when employed for lighting or heat ing. Hitherto it has been customary when, for example, it has been required to increase the lighting eifect either to increase the size of the incandescent mantle which arrangement is unsatisfactory above a certain limit of size owing to uneven illumination of the mantle, or to provide a plurality of burners or mantles upon the one fitting. This latter method has necessitated alterations in the attachments of the burner owing to the special character of the fitting and, further the fitting has been such as to set up eddies with consequent resistance to the passage of the gas or gas mixture.

According to my invention I overcome the above disadvantages by providing a fitting which is such that it may be fitted to any standard burner attachment or mixing chamher and which is provided with any convenient number of burners or mantle supports as may be desired depending upon Whether the burner is required for heating or lighting.

The invention also consists in forming the fitting in such a manner that it ofi ers little or no resistance to the passage of the gas or gas mixture.

The accompanying drawings illustrate one mode of carrying out the invention.

Figure 1 is an elevation showing one convenient form of burner adapter constructed in accordance with the invention. Fig. 2 is a fragmentary view showing a portion of the adapter in sectional elevation. Fig. 3 is a plan. Fig. 4 is a cross sectional view illustrating an arrangement of valves or plates for closing the conduits or pipes; Fig. 5 is a similar view of a modified form of closing device; and Fig. 6 is a vertical sec- Specification of Letters Patent.

tional view through a fragmentary portion of the structure shown in Fig. 5, in connection with the burner.

In carrying my invention into effect in one convenient manner when applying it, for example, to a burner for incandescent gas lighting I provide a fitting in the form of a plug (1 having a recess 5 therein provided with a suitable standard gas thread andbeing of such a size that it may be readily adapted or fitted to any standard form of burner attachment or mixing cham ber. Into the plug a which may have its lower portion coned or tapered as shown I fit any convenient number (four being shown in the drawing) of pipes c, the pipes communicating with the interior of the plug and being set at an angle or inclined to one another so that the inner walls of concentrically centered apertures in the body of the plug where they meet the lower face of the recess 2) in the plug form a sharp wel1- defined edge or point cl so that little or no resistance is ofiered thereby to the passage of the gas or gas mixture which is evenly distributed among the various pipes comprised in the burner. When, as above stated, the burner is required for lighting the free ends of the pipes or tubes 0 may be provided with any usual form of attachment or mantle support 6.

If desired when employing a number of pipes or tubes with the burner I provide a plurality of plates as shown in Fig. l, arranged to cut oil one or more of the pipes from the gas supply, the plates being arranged, for example, to be eccentrically mounted upon the body of the plug-like member a and to slide gas-tight between an upper and lower portion thereof so that upon rotation about the point of support each plate will close one of the pipes to the supply. In lieu of the above, as shown in Fig. 5, a single plate or disk concentrically mounted in the plug is provided to simultaneously close or uncover the passages.

In the form of the invention shown in F iof the drawings, the plug a is provided with a plurality of radial. slots f similar in number to the number of pipes or tubes, and pivoted in each slot is a lever 9 having a portion projecting outwardly of the plug and having each a circular plate 72,

designed to be shifted to cover or uncover its respective aperture 1n the ad acent pipe or tube or to uncover said aperture to a cera the body of the-plug and having a projection or arm '70 by which it may be turned so that'through the instrumentality of spaced recesses Z and intermediate plate portions m, the device may be covered or uncovered.

Although I have illustrated my invention in its application to an inverted burner for lighting purposes it will be obvious that it-is equally applicable to an upright burner and, further, the invention is not to be confined to any particular number of pipes or tubes employed in my improved form of fitting and the construction and arrangement may befsuitably modified depending upon the purpose for which the burner is to be employed. It will also be clear that the mixing chamber need not necessarily be situated intermediate of the fitting plug and the source of gas supply.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is 1. In an attachment for Bunsen burners,

a'plug adapted to be fitted to a suitable burner and a plurality of pipes fitting into i said plug and arranged in an inclined mannor, the bores of said pipes being continued within theplug so that the part of the plug between the pipes takes the form of a sharp edge or point, said edgeor point being situated centrally in the path of the entering stream of gas or gaseous mixture, and means for cutting off the gas supply from one or more of the tubes.

2. In an attachment for Bunsen burners, a plug adapted to be fitted to a burner fixture, a recess within said plug, a plurality of tubes fitting into said plug and arranged in an inclined manner, a sharp edge or point formed within said plug by the continuation of the bores of the pipes, said edge or point being situated centrally in the path of the entering stream of gas or gaseous mixture, a plurality of radial slots in said plug, and means moving in said slots adapted to open or close the respective tubes.

3. An attachment for Bunsen burners, comprising a plug or fitting adapted to be fitted to any suitable burns and a plurality of tubes fitting in said plug and arranged in an inclined manner, said plug having separate passages alining with the bores of the tubes to form a sharp edge or point at the meeting portion of the tubes whereby the gas is uniformly divided and deflected directly through the tubes with a minimum resistance.

l. An adapter of'the class describcd,comprising a fitting adapted for attachment to a standard burner, a plurality of tubes detachably secured in said fitting, said fitting having a central portion and apertures produeing a sharp central edge and recesses in the interior wall thereof communicating with the bores of the tubes, means carried by the fitting adapted to cut off the gas supply from the tubes as desired, andv means carried by the tubes for supporting gas mantles.

In testimony whereof I aHiX my signature in the presence of two witnesses.
