To WHoM 1T MAY ooNoRN:
Be it known that I, DAVID MANUEL, of Boston, State of Massachusetts, have invented new and'usetul Improvements in Machines for Forming Wire Springs; and I do hereby declare the following to be a full and exact description of the same, reference being had to the drawings that accompanyr and form a part of these speciiieations, in which Figure 1 is a. perspective view of the machine.
Figure 2, detached parts of the portion of the machine to which-my invention relates.
Figure 3, view of u. spring'formed for sprng-bed or upholstering purposes.
Letter A, the form on which the spring is wound; letter B, portion of a hollow spire spindle; 1ct-ter C, the counterpart to B; letter D, a strong thimble, which is made to embrace B and C, as illustrated in Figure 4; letter E, a spiral spring, holding the form A in pluce;` letter F, a spring formed for hed-bottom or, uphols tering purposes; letter L, a. hollow, formed partly in B and partly in C; letter z', tongue of the spring F, which lies in the hollow cylindrical boreof B and C, while the other part of the spring is boing wound upon the form A. In winding these springs, I commence at the small end, forming the shank first.
The object ofA my invention is to provide such improvements in machines for winding wire springs of the `haracter shown, as to give a truc tongue or centre piece, z', and to commence the coil so immediately at theV huso of this tongue z', as to secure a. spring much more perfect in form, and one much less liable to be crushed down and its elasticity destroyed. The form of the spring is not a true c one, but is elliptical, and forms an srch at the apex, which gives much greater strength. Y i
In the formation of this spring I commence at the apex ortsmall end, and having secured. the tongue precisely inthe centre, which is readily done by the use of the couplings B and O, and thimble D, I next wind the arch, and. finish at the base ot'- the cone.
What I claim, and desire to secure by Letters Patent, is-f 1 4 The couplings B and C, with the thimble D, in combination with frame A, as and for the purposes specified.
i DAVID MANUEL.
