UNITED STATES PATENT OFFICE.

HARRY DAIN IIINKS, OF BIRMINGI-IAM, ENGLAND.

LAMP-EXTINGUISHER.

SPECIFICATION forming' part of Letters Patent No. 437,782, dated October 7, 1890. Application filed March 10, 1890. Serial No. 843,436. (No model.) Patented in England January 27, 1890. No. 1,397.

To a/ZZ whom it may concern:

Be it known that I, HARRY DAIN 1-I1NKs,a subject of the Queen of Great Britain, and a resident of Great I-Iampton Street, Birmingham, in the county of iVarwick, England,'

have invented certain new and useful Improvements in Lamp Extingnishers, for which I have applied fora patentin Great Britain, No. 1,397, bearing date January 27,1890,) of which the following is a specification.

My invention relates to improvements in extinguishing mechanism for lamps, as hereinafter described.

Usually -that is, in present practice-for the purpose of raising the extinguishers a joint is made upon the burner-body to receive the fulcrum of the Operating-level' and its joint-pin, a fnlcrum hole or bearing being also of course necessary in the lever itself; and the object of this my invention is to provide an arrangement whereby the fnlcrnmjoint hole upon the lever and fulcrum-pin and the interferencc with the ordinary perforations of the burner-body are dispensed with. I attain these objects by the mechanism illustrated in the accompanying drawings, in whichi -Figure 1 is a Vertical section of a burner embracing this my inrention, showing the extinguishers down. Fig. 2 is a Vertical section showing the extinguishers raised. Fig. 3 shows an end view with the extinguishers down, and Fig. 4 shows an end view with the extinguishers raised.

Similar letters refer throughout the several views to the same thing or part.

Instead of interfering with the ordinary perforations in the burner-body in order to form a fulcrL1n1-joint,suoh perforations are carried continuously around. In the bottom a of the burner I make a small hole at Z). I now cut out or stamp a rocking leVer-bar c, having no fulcrum-hole for a joint-pin, but having upon its under side a projection or tooth d, which enters freely into the said hole b in the bottom a of the burner. This forms a rockin g fulcrum.

By reason of the lever or rocking bar being engaged at its inner end e with the central Vertical slide f, attached to the extinguishers g g, and again engaged by the aforesaid tooth din the hole b, and, further, in its passing through the slot h in the body of the burner, it is held or Controlled in its acting position without the aid of the usual fulcrum-pin, which not only dispenses With such pin, but also with much of the friction existing in its use.

The outer end of the lever or rocking bar is suitably shaped to suit taste or design.

In using this my iniproved rocking bar with extinguishers having no Springs upon their flaps, but which are closed by atrip actiJn, (similar as described and illustrated in English specification No. S08, of 1888,) a downward pressure upon the exterior of the lever only is necessary, inasmnch as their own Weight is sufficient to bring them down aga-in into position. r-l`his trip action operates as follows: The shutters or fiaps i z' are provided with inclined armsj j. (See Figs. 5 and 6.) cis a fixed upright, the top of which is provided with stop-pieces Z. Z. When the sliding extinguishers g g have been lifted nearly to their full extent, the two inclined arms jj strike against the stop-pieces Z Z. The continued motion of the slidin g ext-inguishers causes the said inclined arms to turn upon their pivot-s m m, and thereby to turn the fiaps over and cover the wicks and extinguish the flame.

I am aware that pror to this my iuvention a trip action similar to that described in my specification has been made, and therefore I do not claim any part of such trip action, having described it only for general explanation of the other parts; but,

VVhat I do claim as my invention, and desire to secure by Letters Patentof the United States, is-

The combination, with the sliding extingnishcrs of a lamp, having fiaps 'i and arms j, which are actuated by a trip-stop Z Z, and with the sliding bar f, of the rocking lever-bar c, having a controlling projection d taking into the hole b, constructed and Operating substantially as herein described, and illustrated upon the drawings, and for the purposes specip Wit-nesses:

ARTHUR J. PHILLP, ERN. W. JONES.
