ADJUSTABLE SUPPORT FOR VAPOR-LAMPS.
, Specification of Letters Patent.
Patented Oct. 13, 1908.
Original application filed July 28', 1904, Serial No. 218,473. Divided and this application filed January 9, 1906.
Serial No. 240,274.
To all whom it may concern:
Be it known that I, STANWOOD E. FLIoHT- NER, a citizen of the United States, and resident of Englewood, county of Bergen, State of New Jerse have invented certain new and useful mprovements in Adjustable Supports for Vapor-Lamps, of which the following is a specification.
The present invention relates to frames for vapor electric lamps such as are represented by the well-known mercury vapor lam s now in common use. 1
T e special object of the invention is to rovide means whereby the starting of such amps may be readily accom lished either sing y or'in groups by means 0 tilting ap aratus in-which, connection is first made etween the negative and positive electrodes through a stream or column of mercury, and afterwards such connection is broken by a proper manipulation of'the apparatus, so that the current which originally flowed through the vapor column or stream shall pass through the vapor path between the main positive and the main negative electrodes.
It has been found in practice that a variety of tilting frames is required for various purposes, whether for photogra hing by means of mercury vapor lamps, or or printing, enlarging or copying, as the case may be.
This a plication'is a division of my ap )lication fied July 28, 1904, Serial Num er 218,473, and relates to a special application of the invention therein described and shown.
In the drawings, Figures 1 and 2 are, respectively, front and side elevations of an apparatus especially adapted for printing; and Fig. 3 is a side elevation of a modified form of apparatus for the same purpose.
Referring to Fig. 2, of the drawings, I have two lamps, 2, 2 ,'mounted on frames, 1, 1, the two frames being themselves mounted upon standards, 3, 3. Behind the lam sare reflectors, 4, 4, adapted to throw the ight forward upon blue printing paper (not shown) mounted upon a frame, 5, (see Fig. 1). The lamps are suitably pivoted and are mounted upon a carriage, 6, supporting the standards, 3, 3.
This carriage is shown as being adapted to travel under the frame 5 so that the printing frame may be exposed across its entire surface to the radiation of the lamps 2, 2. In
continued until a successful lamp being order to accomplish the starting of the apparatus by ti ping or tilting, the carriage has to be moved i om under the frame5, whereupon the tiltingmay takeplace through the medium of the frame 1 and its supporting rod, 7, which is pivoted in uprights 3, 3. The lamps having been started, the carriage can be moved under the frame and the operation printing is accomplished.
Fi 3 illustrates a similar apparatus, in which, however, the necessit for removing the carriage as described above is avoided. In this construction, the frame 1 is pivoted at 8 in a standard, 9, and the operation of tilting the lam or lamps for starting purposes is accomp iished by releasing the upper end of the frame 1 supporting the lamp or lamps 2 from the standard 3, and tiltin it by hand until the lighting is accomplishe after the position shown in the figure. The free end of the frame 1 is supported upon a suitable shoulder on the standard 3, and may be released therefrom for the urpose of tilting the frame and the lamp or amps 2, by hand for accomplishing the lighting as above set forth.
. In the construction shown in the drawing, it is possible to do away with the necessity of moving the lamps across the field of exposure, by providing suitable reflectors which will diffuse the light over the said field.
I claim as my invention 1. The combination with an inclined frame and a vapor electric lamp supported thereby, of a carriage supportingthe frame and means for tilting the frame upon its carriage for starting purposes.
2; The combination with an inclined frame, of a vapor electric lamp supported thereby, a carriage supporting the frame, the pivoted to the frame near the bottom thereof and means whereby the lamp can be let down at the opposite end for starting pur oses.
Signed at ew York,in the county of New York, and State of New York, this 3rd day of January A. D. 1905.
STANWOOD E. FLICHTNER.
