Description
@mgm WW N.PETERS, PHD! 0-LITHOGRAPHER, WASH UNITED STATES PATENT GFFICE. y
J. J. MCCORMICK, OE PATERS'ON, NEW JERSEY, ASSIGNOR TO HIMSELF, AND J. L.
` 4CANFIELD, OF NEW YORK, N. Y.
SPRING BED-BOTTOM.
Specification of Letters Patent No. 32,235, dated April 30, 1861.
To .all 'whom it may concern:
Be it lknown that I, J. J ..l\/IcCon3UcK, of Paterson, in the county of Passaic and State of New Jersey, have invented a new and Improved Construction ot Circular and Elliptical Springs; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying` drawing, forming a part of this specification, in which- Figure l represents a longitudinal vertical section ot my invention. Fig. 2 is a plan or top View of the same.
Similar letters of reference in both Views indicate corresponding parts.
The object of this invention is to make circular and ellipticalisprings in such a manner that they can no-t only be easily attached or taken oit but so that an eXtra pressure eX- erted on one of the springs has no injurious influence lon its elasticity, and at the same time of simplifying and cheapening the constructions of springs for certain purposes that any carpenter with the most ordinary tools and materials can make and apply such springs.
To enable those skilled in the art to make and use my invention I will proceed to describe its construction and operation with reference to the drawing.
rIhe spring A is made of astrip of sheet steel vor any other suitable material bent as clearly shown in Fig. 1 in the drawing, its ends are secured to the slatB by means of a screw a which passes up loosely through said slat and through the ends of the spring and which screws into a block C placed inside the spring and made of wood or any other hard material which gives a good and lirm hold to the screw, this block C forms a cushion tor-the spring it the latter is dcpressed to its utmost capacity, and the height of this cushion determines the amount of motion allowed to the spring. This cushion is so regulated that if the spring` is subjected to an extraordinary pressure which causes its top portion to come down on the cushion it (the spring) being released 4from the pressure will assume its original form. By these means the spring will preserve its original elasticity under all circumstances and it will be able to sustain any pressure without being injured.
By combining the flat sprinO A with the top plate D and with the cushion C I am enabled to produce a spring superior in its eit'ect, more durable, and cheaper, than the spiral springs which are now in common use for upholstering purposes.
VHaving thus fully described my invention what I claim as new and desire to secure by Letters Patent is- The employment ot the cushion C in combination with the flat spring A and screw a, substantially as described and for the purpose specified.
J. J. MCCORMICK.
