Description
UNITED STATES PATENT Orr-ICE J OSEPH KINTZ, OF MERIDEN, ASSIGNOR TO HIMSELF ANI) P. J. CLARK, OF
WEST MERIDEN, CONNECTICUT.
sMPRovEMEN-r m LAMP-BASES.
Specification forming part of Letters Patent No. 128,048, dated June 18, 1872.
Specification describing a new and useful Improvement in Base for Lamps, invented by JOSEPH KINTZ, of Meriden, New Haven county, State of Connecticut.
Y' My invention consists of a lamp-base in two parts, the lower one being a hollow cup or approXimately cup-shaped plate, with four holes (more or less) through the bottom, and the upper one being a plate covering the hollow one, and having four legs or pins corresponding to the holes through the lower piece, which pins are pressed down upon pieces of soft vulcanized rubber by the bolt which secures the lamp-stand to the base, so as to press the pieces of rubber through the holes enough to support the base above the table, and thus prevent it from scratching or injuring it.
Figure 1 is a transverse sectional elevation of my improved lamp-base taken onthe line x of Fig. 2; and Fig. 2 is a horizontal section on the line y y of Fig. l.
A is the hollow bottom piece, which may be constructed in any approved form suited for a lamp-base. B represents the holes, through the bottom of which there are, preferably, four, but may be more or less, as preferred. C is a cavity in the lower side of said plate, as in other lamp-bases, to provide room for the nut D of the screw which attaches the lamp-stand. E is the top plate, which is large enough to cover the top of part A, and is, preferably, rabbeted at F to set down inside slightly, and to prevent lateral movement on A. G represents the legs or pins on the under side of plate E, arranged to come in the holes where the two pieces are fastened together, but to extend through the holes only a little, if any. H represents the pieces of soft vulcanized India rubber, placed over the holes and passed through them by the pins for rests for the base, as clearly shown on Fig. 1, constituting soft bearing-pieces that will not injure Witnesses:
