UNITED STATES PATENT JOSEPH KINTZ, OF BALLARD VALE, MASSACHUSETTS, ASSIGNOR TO HIMSELF AND THE CRAIGHEAD & KINTZMANUFACTURING COMPANY, OF MASSA- CI-IUSETTS.

SUSPENSION-LAMP.

SPECIFICATION forming part of Letters Patent No. 400,856, dated April 2, 1889.

Application filed October 4, 1888. Serial No. 287,206. (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 Massachusetts, a citizen of the United States, have invented certain new and useful Improvements in Suspension-Lamps, of which the following is a specification.

My invention relates to that class of suspension-lamps in which a spring-actuated winding-drum is employed to take up and release the suspensionchains by which the lamp-fixture is hung from the ceiling, this drum having its motion controlled by a springlatch having a connection extending to the lower portion of the fixture, by which the latch may be opened when it is desired to raise or lower the lamp.

In the accompanying drawings I have represented at Figure 1, in vertical section, a suspension-lamp embodying my present improvement, and at Fig. 2 an enlarged view of details of the apparatus, as will be hereinafter more fully explained.

The drawings show a fixture comprising the raising and lowering drum A, supportingchains B B, winding and unwinding from said drum, supports C 0, preferably chain, extending from the drum-case downwardly to the shade-ring D, pendent from which are brackets supporting the lamp-fount-cup support E also, I have shown in connection with the drum a latch, F, mounted upon a spring, G, within the drum-case, and provided with an exten sion, II, passing downwardly through the drum-case. All the parts thus far described are substantially such as have been heretofore employed in lamps of this character.

The immediate object of my present invention is to so construct and arrange the connection whereby the spring latch F may readily be operated from the lower part of the fixture, when it is desired to raise or lower it, that the same shallbe both graceful in appearance, simple in construction, and easy in operation. I accomplish these results by means of the following mechanism: Attached to the lower end of the extension H is a bent rod or cross-bar, I. From the extremities of this cross-bar I chains K K descend, and their lower extremities are connected with the upper ends of the arms of a stirrup, L, adapted to conform substantially in its shape to the outline of the lamp-fount-cup support and to move vertically within the same. To the lower part of this stirrup is attached a downward connection, M, terminating in a suitable finger-graspas, for example, the ring N.

With the construction above described a neat, simple, and convenient device is af- 6o forded for operating the spring-latch from the lower part of the fixture.

It will be understood that the tension of the spring G, which normally holds up the latch F in engagement with the drum, also causes the stirrup L to be lifted or held up by reason of the connection through the chains and cross-bar. VVheu now it is desired to withdraw the latch, in order to permit the drum to revolve, to raise or lower the fix- 7o ture, this may be done by pressing down the ring N, and so long as this is held downward the fixture may be raised or lowered. (See Fig. 2.) WVhen the pressure upon the ring N is released, the latch F is free to move upward, under the tension of the spring G, to engage with the drum and stop its revolution, thereby holding the fixture in suspension.

The location of the stirrup L within the lamp-fount-cup support is a desirable feature, because this stirrup is necessarily of fragile construction, and being Within the lamp-fountcup support, is thereby protected from accidental injury by a blow or otherwise. Furthermore, the passages or holes in the upper portion of the lamp-font-cup support, through which the arms of the stirrup move, serve to center it and prevent it from turning, and thus, the lamp-fount-cup support itself being utilized for this purpose, no addio tional guides for the stirrup need be provided.

I am aware of the structures described and shown in United States Letters Patent No. 285,381, dated September 26, 1883, and No. 311,224, dated January 27,1885, and disclaim as of my invention anything therein shown or described.

I claim In a suspension-lamp of the character described, the combination, with the mechanism I00 which controls the motion of the raising and lowering drum, of a hollow lamp-fount-cup support, E, a stirrup, L, located and vertically movable therein and having its upper portions passing through the upper portion of the lainp-fount-eup support,2t finger-grasp,N, attached to the lower part of the stirrup, and connections K, extending upwardly from the upper ends of the said stirrup and attached to the extremities of a C1OSSbL1,I, connected with the drum-controlling latch, all substantiztlly as set forth.

In testimony whereof I have hereunto sub- 1o scribed my name this 25th dayof September A. D. 1888.

JOSEPH KINTZ.
