.SPECIFICATION forming part of Letters Patent No. 617,317, dated January 10, 1899.

I Application filed February 23,1898. Serial Nth 671,345. (No model.)

To all whom it may concern;

Be it known that W6,FREDERICK E. CHURCH and WILLIAM C. ALLEN, citizens of the United States, residing at Cambridge, in the county of \Vashington, State of New York, have invented certain new and useful Improvements in Wire-Coiling Machines, of which the fol-. lowing is a specification, reference being had therein to the accompanying drawings.

This invention relates to wire-coiling machines, and more particularly to a machine for the purpose of producing a coiled-wire handle for articles of various characters.

The invention has for its object to improve the form of maudrelheretofore used for this purpose, so that a coil may be formed surrounding a central shank or stem.

A further object of the invention is F0 pro vide mechanism bywhich the mandrel may be rotated and reciproeated for the purpose of producing a handle having a spiral coil.

Other objects and advantages of the invention will hereinafter appear in the following description, and the novel features thereof will be particularly pointed outin the appended claim's.

In the drawings, Figureil is a diagrammatic. plan of the machine and auxiliary devices. Fig. 2 is a detail vertical crposs-section on the line 2 2 of Fig. 1. Fig. 3 isdetail perspective of the mandrel,.and Fig. 4 is'a detail eleva= tion of the complete coil of the handle.

Like letters and numerals of reference indicate like parts throughout the several figures of the drawings. I

The letter A designates the base-plate or foundation, from which extend suitable bear-- ings A, adapted to receive and support a driving-shaft B. This shaft is provided at one end with an elongated driving-pulley B, and the opposite end of the shaft is formed with a sooketB adapted to receive and retain the mandrel Got any suitable construction. The

shaft B is provided with a feeding-screw B which when engaged by a permanently-located latch D will produce a gradual longitudinal movement of. the shaft B. This latch D is pivoted at D upon-a support D permanently located upon the base A, and at its opposite end is provided with a finger-piece D, adapted to seat between the opposite lugs istohe p1:

the latch may be thrown into and out of engagement with the screw, so that the shaft can be shifted by hand from one extreme of its movement to the other, or when the latch is in engagement with the screw a gradual feeding movement will be produced. The

shaft 13 may be driven by any suitable means-for instance, from a power-shaft E, provided with a fast pulley E and a loose pulley E From these pulleys the power will be transmitted by means of a belt E which in the reciprocation of the shaft will slip upon the elongated driving-pulley carried by said shaft.

The wire from which the handle or article llngedisled fromralsuitable coil F through 'any desired form of straightening or tension device-for instance, as shown at F'and thence through a holder G, provided with a seat G, within which the wire will rest. By this means the wire is held against movement, and when suitably secured upon the mandrel the rotative and reciprocative movement of'the mandrel will producea spiral coil upon the same. The diameter of the coiled handle will be governed by the diameterof the different portions of the mandrel. During this gradual rotative and reciprocative movement of the mandrel to produce the spiral coil the latch is in engagement with; the

threads of the shaft. When the article is completed, the end of the wire severed from the main portion thereof, and the article removed from the mandrel, the shaft may be returned to its initiaL'positionl by simply raising the latch and moving the same by hand D raised from the base A. By this means or by any preferred mechanism. By this] means the mandrel can be at once returned to its initial position and ready for a further.

coiling operation. Q

While any character of mandrel may be. We have illustrated an used .upon this device, improved form of l ollow'mandrel provided with a longitudinal slot 0', extendingv part way of it length, and with a stem 0 adapted to seat in the socket provided at the end of the shaft B and to be securedtherein by any suitable means-for instance, a set-screw C, as illustrated. To prevent any possible-slipping of the mandrel in 'thissoek et, the stem may be formed angular and adapted to seat in a corresponding angular socket.

The form of mandrel just described is particularly adapted for the formation of a handle for carpet-heaters or other devices in which the handle is composed of a twisted shank 1 and surrounded by a spirally-coiled portion 2, reduced in diameter at one end 3 to engage the shank. For the purpose of producing this reduced portion 3 of the handle the mandrel is tapered, as at C the inclination of which tapering portion determining the taper of the handle.

For the purpose of prod ucinga carpet-beater provided with the handle just described the end of the Wire is first formed into a loop 5, the ends of which loop are twisted to form the portion 1. Then in this condition, the portion is centered within the hollow of the mandrel C, and the end of the Wire extends through the slot 0 and rests upon the base. The shaft now being rotated and simultaneously reciprocated produces the spiral coil forming the handle. Vhen the end of the Wire passes beyond the end of the mandrel, it is tightly coiled around the shank-body, and thus the finished handle is produced.

It is obvious that different forms of mandrels may be used with the machine just described and that the mandrel specifically described may be applied to other forms of operating mechanisms. The details of construction and the auxiliary parts may likewise be altered Without departing from the spirit of the invention as defined by the appended claims.

Having described our invention, what we claim, and desire to secure by Letters Patent, 1s

1. In a wire-coiling machine, the combination with a base, of a shaft provided with a feeding-thread and adapted to rotate and reciprocate, a pivoted gravity-latch supported upon the base to engage the upper face of said thread, a projecting finger-piece to said latch for releasing the same from the thread, and supports at opposite sides of the shaft to retain said latch against lateral movement; substantially as specified.

2. In a wire-coiling machine, the combination with a base, of a shaft provided with a feeding-thread and adapted to rotate and reeiprocate, base to engage said thread,astationary holder,

and a hollow mandrellprovidedswith a longil tndinal slot; substantially as specified.

3. In a Wire-coiling machine, the combinasocket at one end,

a pivoted latch supported upon the tion with a base, of a shaft mounted thereon, meansfor rotating and reciprocating said shaft, a Wire-holder located on said base, and a hollow cylindrical mandrel adapted to receive the shank of a handle to be coiled and provided with a longitudinal slot or recess communicating with the center of the mandrel; substantially as specified.

l. In a wire-coil machine, a hollow cylindrical mandrel having a tapering end portion and provided With a longitudinal slot; substantially as specified.

5. In a Wire-coil machine, the combination with a support, of a driving-shaft adapted to rotate and simultaneously reciprocate, a hollow mandrel provided with a longitudinal slot and carried by said shaft, a wire-holder supported upon the base, and a straightening device through Which the Wire passes before reaching said holder; substantially as specified.

6. In a wire-coil machine, the combination with a support, of a driving-shaft adapted to rotate and simultaneously reciprocate, a hollow mandrel provided with a longitudinalslot and carried by said shaft, a Wire-holder supported upon the base, an elongated drivingpulley upon one end of said shaft, and a belt extending from said pulley to a driving-shaft; substantially as specified.

7. In a Wire-coil machine, the combination with a base, of a reciprocating and rotating shaft supported thereon and provided with a means to produce the re ciprocation and rotation of said shaft, a hollow cylindrical mandrel provided with a longitudinalslot and removably carried by said shaft, and a stationary wire-holder adjacent to said mandrel; substantially as specified.

8. In a wire-coil machine, the combination with a base, of a reciprocating and rotating shaft supported thereon, means to produce the reciprocation and rotation of said shaft, a hollow cylindrical mandrel provided with a longitudinal slot and carried by said shaft, a stationary wire-holder adjacent to said mandrel, a feeding-thread upon said shaft, and a stationary pivoted latch to engage said thread; substantially as specified.
