LAMP-BURNER.

SPECIFICATION forming part of Letters Patent No. 477,034, dated J' une 14, 1892. Application iiled August 19,1891. `Serial No. 403,127. (No model.)

To all whom it may concern;

Beit known that I, FRANK THEoDoEE WIL- LIAMS, of Meriden, in the county of New Haven and State of Connecticut, have invented a new Improvement in Lamp-Burners; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent a view in side elevation of a lampfount,a burnersocket, and a burner-slip constructed in accordance with myinvention and arranged one above the other in the order of their assemblance.

My invention relates to an improvement in central-draft lamp-burners, the object being to produce a simple and cheap burner in which the burner-slip may be disconnected from the burner socket for cleaning the burner without disconnecting the said socket from the lamp-fount.

lVith these ends in view myinvention consists in the combination, with aburner-socket having one or more double-ended bayonetslots formed in its flange, of a burner-slip having one or more simple bayonet-slots formedin its flange, and whereby the turning of the burner-slip to disconnect it from the burnersocket will turn the same and change one end of its double-ended slot for the other end thereof with respect to the retaining nub or point entering the said slot from the lampfount, with which the burner-socket is thus kept coupled.

The burner-slip A is of ordinary construction and has the ordinary bayonet-slot B formed in its iiange, which co-operates with an inwardly projecting nnb or retainingpoint B', formed by striking in a portion of the flange of the burner-socket C, which is also of the usual construction, with the exception that its bayonet-slotD, formed in its lian ge, is double-ended, or, in other Words, extended laterally in both directions to form two ends CZ and d. The said double-ended slot D cooperates with a nub or retaining-point D', formed by striking inward a portion of the flange E of the collar E', permanently attached to the lamp-fount F. Vhen under the above-described construction the burnerslip is turned in the direction of the arrow a to disconnect it from the burner-socket for cleaning the burner, the friction between it and the said socket will cause the same to be turned, also, in the same direction, whereby the end d of its double-ended bayonet-slot is changed for the end CZ' thereof with respect to the retaining-point D' and the coupling between the burnersocket and the lampfount maintained, so that the said socket will not be removed from the lamp-fount when the burner-slip is lifted to disconnect it from the burner-socket. Vhen the burner-slip is replaced upon the burner-socket and turned in being connected therewith, the burnersocket also turns again, whereby the end d' of its double-ended bayonet-slot is changed for the end d thereof with respect to the retaining-point D', with which the said end d is normally engaged. It will thus be seen that my improved construction provides extremely simple and inexpensive means for constructing a burner with a removable slip, which may be taken oft and replaced at pleasure without disconnecting the burner -socket from the lamp-fount. Although, as shown in the drawings, the burner-socket and burner-slip are each provided with only one slot, they will be ordinarily provided with two each, the slots of the slip quartering, so to speak, with those of the socket.

I am aware that it is not new to couple a burner-slip and a burner-socket together by means of a simple bayonet-lockinvolving the very objection which it is the purpose of my present invention to avoid-that is, the accidental removal of the 'burner-socket with the burner-slip when it is intended only to remove the latter. Thus it is that, while heretofore burner-sockets have had simple or oneended bayonet slots, I provide them with double-ended bayonet-slots, which are the characteristic and novel feature of my present invention.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, isl In a lamp-burner, the combination, with a IOO burner-soeket having one or more doubleended bayonet-slots formed in its ange, of a burner-slip having one or more simple bayonet-slots formed in its flange, substantially as set forth, and whereby the turning of the burner-slip to disconnect it from the burnersooket will turn the same and change one end of its double-ended slot for the other end thereof with respect to the retaining nnb or 1o point entering the said slot from the lampfount, with which the burner-socket is thus coupled.

In testimony whereof I have signed this speeieation in the presence of two subscribing witnesses.

F. TI-IEODORE WILLIAMS.
