UNITED STATES PATENT OFFICE;

JOSEPH KINTZ, OF BALLARD VALE, MASSACHUSETTS, ASSIGNOR TO HIMSELF AND THE ORAIGHEAD & KINTZ MANUFACTURING COMPANY, OF MASSA- CHUSETTS.

EXTENSlON-CHANDELIER.

SPECIFICATION forming part of Letters Patent No. 400,857, dated April 2, 1889.

Application filed October 24, 1888. Serial No. 289,047. (No model.)

To all whom it may concern;

Be it known that I, JOSEPH KINTZ, of Ballard Vale, in the county of Essex and State of lvlassachusetts, a citizen of the United States, have invented certain new and useful Improvements in Extension Chandeliers, of which the following is a specification,

My invention relates to that class of lightcarrying fixtures in which a suitable light= carrier is suspended from the ceiling by means of chains winding and unwinding upon a spring drum, the revolution of which is controlled at pleasure by a catch adapted to be operated from the lower part of the fixture. Its object is to improve certain details of construction of such mechanism. 1

In the accompanying drawingl have shown at the figure in vertical section a complete apparatus embodying my present invention, which I will now proceed to describe.

A A represent the supporting-chains of the fixture, through the instrumentality ofwhich it is suspended in place for use.

B represents a spring-drum, upon which the chains A A are wounch The revolution of the drum when the fixture is lowered tends to wind up its spring, which, when wound, tends to revolve the drum in the opposite direction and so to assist in the operation of raising the fixture. The lower face of this drum is provided with notches 1) arranged in a circle; The drum is inolosed within an ornamental case, 0, a perforated frame, 0, extending across the said case below the drum.

At the lower part of the drum-case O is a catch-piece, D, mounted upon and normally held up by a vertical coiled spring, cl. The upper end, d, of this catch-piece is forked, as shown, the extremities of the forks passing through the perforations in the plate 0 and normally engaging with the notches b to prevent the revolution of the drum B.

Attached to the lower part of the drumcase is a hollow depending tubular shell, E, in the upper part of which is secured a bushing, 6, which serves as an abutment for the spring d, above mentioned, and through which the catch=piece D is free to move vertically. The shell E at its lower extremity is 50 connected with a hub, G, which carries one or more laterallyproj ecting lamp-sockets, G This hub, like the shell E, is hollow, and the chain F, before mentioned, passing down through the hollow shell and hub, is attached at its lower end by means of a pin, f, to a finger slide I, surrounding a hollow tubular shell, J which depends from the lower portion of the hub G, and which is slotted, as at 9', to allow for vertical motion of the fingerslide I and pin f.

The operation of the device is as follows: The drawing represents the fixture as at practically the highest point of elevation and at rest, the catches engaging with the notches on the drum to prevent its rotation, and the spring within the drum being unwound. If, now, itvis desired to lower the fixture, downward pressure upon the finger-piece I, com= municated by means of the chain F to the catch-piece l), releases the fork d from the notches on the drum-plate, and leaves the latter free to revolve. The fixture may now be held down, and so long as downward pressure is kept upon the finger-piece I it may be raised or lowered at will. When the pressure is relieved from the finger=piece I, the. upward thrust of the spring d brings the fork d into contact with the notches b of the drum and holds the fixture in suspension.

The perforated plate 0, through which the So fork D works vertically, serves as a guide to it in its vertical motion and prevents it from being accidentally twisted, by the twisting motion which might be given to the catchpiece D under the influence of its actuated spring.

I am aware of the matters set forth in United States Letters Patent No. 285,381, dated September 25, 1883, and No. 311,224, dated January 27, 1885, and hereby disclaim as of my in-\ go Vention anything therein shown or described.

In an extension-chandelier, the combina-- tion of the supporting-chains A A, winding= drum B, provided with notches b on its under side, the drum=case 0, provided with the internally-located perforated plate 0, the catch piece D, having a fork, 01', arranged to work vertically through the perforations in the said plate to engage with the said notches, the Ice coiled spring cl, supporting said catch-piece, the shell E, hub G, shell J, provided with the Vertical slots j j, finger-slide I, surrounding the said shell J and provided with a pin, f,

fixture may require, all substantially as set 10 forth.

I11 testimony whereof I have hereunto subscribed my name this 20th dayof October, A.
