WILLIAMLORD, Vor sauf/FRANCISCO, oALIronNIA.
`Letters Patent N0. "106,069, dated August 2, 1870.
` IMPROVE;4 SPRING FOR BEDS, sores, ecc.
The ,Schedule referred to in these Letters lihate'xit4 and making part of the same.
, To all whom it may concern i Beit known thatI, WILLIAM LORD, ofthe city `andcounty of ,San Francisco, State of California, `have invented an'linproved `Spring for Beds, Sofas,
Chairs, 85e; and I do hereby declarey that the follow# ing is afnll, clear, vand exactidescripti'on of the same, refe'rene i being had. to the accompanying drawing and to the letters niarked thereom- 'l My invention relates to that class of spiral springs in which the radii o f the coils increase fromfthe cen- ,tertoward the ends of i thespling.
The object of myinvention is to-provide an improved spring for general use,' and particularly for chairs,-
`sofas, or other-seats, `and for beds, a'nd consistsin the employment, with a spiral spring, of a central rod rigidly secured toa cap', 4and guided by a hollow standard, said standard being secured toa base; and further consists of an improved device ,for securing `the ends ofthe spiral spring to said cap and base; also," of'` interposing' between the cap and'` hollow Vstandard 4an. India-rubber spring encircling the centrai rod, in order to prevent the inelastic parts of the machine from coming together, in case the spiral spring is overloaded, the whole arranged in snob a manner as to'form a spring that has a true rectilinear action, is not easily put out of order, and ycan be readily applied to any desired purpose, either singly or in numbers. i
,l In the ccompanyingdrawing- Figure 1 is a longitudinallsection of'\"xny improved spring. y y, Figure2 is a view ot under side of cap, showing i fastening' of spiral 'spring and other details.
4Figure 3 is a cop` view of base, showing the hollow or guidingstandard, l l
` Like letters refer to like part-s in all of the figures.
A is the spiral spring.
B, the base.
C, the cap. D, the central rod, rigidly secured to the clamp or shoulder-pieceE by means of screws F', as shown.
G is the hollow guide-standard, secured to the base by means ofthe screws H.
I is acylindrical rubber spring, through which the rod D passes. 1
y .J are clamp-pieces that firmly secure the end coils of the spiral spring to the cap and base, by means o t' the screws K. l i
It vis evident that the hollow standard Gr will effectually guide the rod D,'so that, when my invention is in operation', the cap Gvwill approach or recede from the base B in a straight line, and that, if the spiral spring should he' overloaded, thevrubberspringwould v prevent the contact of the inelastic faces oi' the stand` Witnesses G. W. M; SMITH, l DAVID R. SMITH. l
