ANDREW B. IVILBUR, OF BALTIMORE, MARYLAND.
MAKING SPIRAL SPRINGS.
SPECIFICATION forming part of Letters Patent No. 234,830, dated November 23, 1880.
Application filed October 8, 1880.
To all whom it may concern:
Be it known that I, ANDREW It. \VILBUR, of Baltimore city, State of Maryland, haveinvented a new and Improved Tool for Making I/Vire Spirals; and I do hereby declare that the following is a full, clear, and exact description of the same.
My invention relates to an improved handtool to be used principally by jewelers, that will enable them to rapidly make small wire spirals for shirt-studs; and the improvement consists, primarily, in a mandrel secured to an ordinary tool-handle, a carrier fitted upon the lower end of the mandrel to revolve around it, and a presser-bar pivoted upon the carrier, the parts being so arranged that the wire may be secured at one of its ends to the end of the mandrel and the presser-bar held against the wire and revolved around the mandrel and moved up and down upon the same and coil the wire closely around it.
My invention also consists in certain details of construction, hereinafter more fully described, and particularly pointed out in the claims.
In the accompanying drawings, Figure 1 is aside elevation of the improved tool; Fig. 2, a perspective View of the wire-holder; Fig. 3, a similar view of the end of the mandrel upon which the said wire-holder fits; Fig. 4, an enlarged sectional detail of the eye-plate that holds the end of the wire while it is being coiled. Fig. 5 is a perspective view, in detail, of a spiral formed by the improved tool; and Fig. 6, a sectional plan, in detail, in line as w of Fig. 1.
An ordinary tool-handle, A, such as is used upon awls and files, has secured to its end a rod or mandrel, B, of a size to correspond with that of the spiral, H, to be formed. The end of the mandrel nearest the handle is formed with a screw-thread of a pitch to conform to that of the spiral. V
The carrier is formed of a nut, 0, post D, guide-lever I, and presser-bar E. The nut is screw-threaded to fit the mandrel, so that as it revolves the carrier will be revolved and moved upon the mandrel from end to end. The presser-bar is pivoted upon the end of the post above the guide-lever I, which latter is (No model.)
journaled upon the mandrel to hold the carrier firmly in place upon the mandrel, and the presser-bar is pivoted above said guide-lever in such manner that the outer end of lever E may be pressed upon with the ends of the fingers to firmlyhold the other end against the mandrel and press upon the Wire. lar, F, upon the mandrel will determine the length ofthe movement of the carrier.
A col- Athimble-shaped holder, G,is made to snug- 6o lyfitover the end of the mandrel, and is formed with an eye-plate, 9, arranged diametrically across its end, that fits in a slot, 1), in the end of the mandrel. that passes through it, and is of a size to receive the end of the wire. the wire is placed in the hole 9 a suitable distance it is bent down at right angles, so that it will pass beneath the plate and through the slot 1) to the outside of the mandrel. means the end of the wire is securely held when the presser-f0ot is forced against it to bend the wire.
The plate 9 has a hole 9,
When the end of By this In using the instrument the handle is held and revolved by one hand, while the mandrel is held by the ends of the fingers of the other hand, so that the presser-bar will rest upon the fingers and be prevented from turning when the handle and mandrel are turned.
Instead of securing the end of the wire to The The tool may be made to work with good 0 effect without the screw-thread upon the mandrel but the convolutions of the wire will not be formed so regularly and quickly as when the screw-feed is used in connection with the carrier. 5
The above-described tool may be used for coiling wire to form springs, or for any similarpurpose.
What I claim as new is- 1. In a tool for bending wire into coils or 00 spirals, the combination of the handle, the mandrel provided with means for holding the end of the wire, and a carrier journaled upon the mandrel t0 revolve and move alongits length, these parts being combined and arranged to operate substantially as described.
2. The handle having screw-threaded mandrel, in combination with the nut encompassing the screw-threaded portion of the mandrel, the post attached to said nut, the guidelever pivoted around the mandrel and con nected with the end of the post, anda presserbar pivoted to the top of the guide-lever and adapted to co-operate with the guide-lever, as described.
3. The combination, with the mandrelB, having a diametrical slot, 1), in its end, of the thimble G, arranged to fit over the end of the mandrel and having a diametrieal plate, 9, arranged to fit in the slot 1), and having a central hole, g, substantially as and for the purpose described.
