IMPRovEMEN-r IN STANDARDS Fon onor-LIGHTS.
Speciicationforming partof Letters Patent No. 115,442, dated May 30, 1 871.
To all whom t may concern: i
Be it known that I, JAMES CUNNINGHAM, of West Meriden, inthe county of New Haven and State of Connecticut, have invented a new Improvement in Standard'for Drop-Light; and
I do hereby declare the following, when taken in connection with the accompanying drawing and the letters ofreference marked thereon, to bea full,- clear, and exact description of the'same, and which said drawing constitutesupart of this specilcatiomand represents,
Figure 1, a side View; Fig. 2, a vertical central section; Fig. 3,'a side view of the pack-y ing-cylinder; Figzi, the `pli1g;'and in Fig. 5, the lubricating and packingspring. Y `v This invention relates to `an improvement in packing device for slides, epecially adapted y for drop-lights of gas-fixtures, but applicable for other purposes. 4Various' devices have been Aemployed for this purpose, butin all there, are some' objectionseither leaking of the gas, or too much or too little friction, and
also an unequal lubrication. `To overcome these diiiiculties is the object of my invention,
. i which consists in combining with a standard a cylinder, through which the said standard passes, and within which` cylinder, around the said standard, is arranged a spiral spring bearing against a packing at one end, with a sim- `ilarpackin'g at the other end adjusted by a screw-plug screwing into the cylinder to compress the spring.
I represent my invention as applied to a gas fixture. A-is the standard or tube of the drop-light, which passes through a cylinder, B, to the upper. end of which the gas-pipe is attached, the tube A running up intol the gaspipe. Thecylinder B is closed at the upper end aroundthe tube, and is of such relative diameter to the tube A `as to form a chamber,
t C, within the cylinder around the said tube.
A packing, a, tting closely the tube A, is inserted against the upper head ofthe cylinder B Then into the cylinder, and bearin g against the packing, aspring, D, is inserted, the said spring shown detached in Fig. 5, and is formed,by preference, from square wire of a size to nearly ll the chamber within the cylinder, and formed at both ends to give a direct bearing on the packing entirely around the cylinder. The
spring inserted, the lubricating materialis introduced with it, completely. lilling the chamber, or nearly so. Then onto this a packing,
I), is set, and the plug E screwed into the tube, as seen in Fig. 2, compressing the spring until the requisite amount of friction is attained to support the burner attachedY to the' tube A. The spring, at the saine time that it serves to adjust the friction, serves also to distribute the lubricating material around the tube.
. It will be observed that'this manner oi' packing may be appliedto shafting and various other purposes where a tube or shaft is to Work through or into a cylinder, and, therefore, when I use the expression tube, describing the part A, I wish to be understood as embracing, also, a rod or shaft.
I do not wish to be understood as broadly claiming the arrangement of a spring and packing within the cylinder, as such, I am aware, is not new.
I claim as my invention- In combination with the tube A and cylinder B, the spring D arranged within the cyll inder, the packing a b, and adjusting-plug E, substantially in the manner herein setforth.
JAMES CUNNINGHAM.
