HARVEY J. MITCHELL, OF RIVERTON, NEW JERSEY.
MACHINE FOR COlLlNG METAL.
SPECIFICATION forming part of Letters Patent No. 747,203, dated December 15, 1903.
Application filed January 3, 1903. Serial No. 137,662. (No model.)
To all whom it may concern,-
Be it known that I, HARVEY J. MITCHELL, a citizen of the United States, residing at Riverton, in the county of Burlington, State of New Jersey, have invented new and useful Improvements in Machines for Coiling Metal, of which the following is a specification.
My invention consists of a'machine for coiling metal embodying a former composed of novel parts and also means for adapting said former to coils of varying diameters or sizes.
It also consists of novel details of construction, as will be hereinafter described, and pointed out in the claims.
Figure 1 represents a side elevation of a machine for coiling metal embodying my invention. Figs. 2 and 3 represent views of op posite ends thereof. Fig. 4: represents a vertical section on linem m, Fig. 1. Fig. 5 represents a section of a portion on line y y, Fig. 3. Figs. 6 and 7 represent views of coils the product of the machine.
Similar letters of reference indicate corresponding parts in the figures.
Referring to the drawings, A and B designate rotary shafts which are mounted on suitable housings A and have the spur-wheels 0 connected therewith, which are geared together by the idler D, whereby motions are imparted in the proper direction to said shafts, the working mandrel E of the latter being provided with the shoulderF. On the ends of the shafts A, surrounding the mandrel E, are rolls G, whose peripheries are adjacent to the side of said shoulder F, said mandrel, rolls, and shoulder constituting the former of the machine. The openings on the housings for the shafts A are enlarged or elongated, as at H,whereby the adjacent portions of said shaftsmay be moved toward and from each other, and said shafts are provided with grooved pulleys J, around which is passed a rope, chain, or other belt is, the ends of the latter being connected at different places with the lever L, which is mounted on the adjacent housing, whereby by properly operating said lever, the shafts A, and consequently the rolls G, may be moved toward each other and toward the shoulder F, and when said lever is released said parts return to their normal position, as will be apparent in Fig. 3. To limit the outward motions of the rolls G in their separation from the mandrel E, I employ the screws M, which are mounted in the adjacent housing outside of the shafts A and in line with the elongated openings H, so that the bearings of said shafts A of said rolls when so separated will abut against said screws, as shown in Fig. 4, the efiect of which is evident.
Mounted on the side of the housing adjacent to the shoulder F is a'lever N, which is provided with a tapering nose P, the latter being adapted when desired to bear against .the convolutions of a coil during formation, so as to spread the same as shown in. Fig. 7.
The operation is as follows: Power is applied to the shafts A B, and a bar, rod, or piece of wire to be formed into a coil is applied to the mandrel E and primarily bent around the same to a limited extent. The lever L is operated so as to close the rolls G against the bar, 850., and the latter is backed against the shoulder F and rotated with the mandrel while being supported on the latter and subjected to the pressure of said rolls G, thus converting the bar, 850., into a spiral or coil, which as its convolutions increase is moved along the mandrel, in the present case to the right, as will be seen in Fig. 1. As the rolls G rotate the belt K yieldingly engages with the shafts A and is held stationary, said rolls, however, remaining in their closed condition. When the coil is completed, the lever L is released, whereby the rolls G separate and relieve the coil of pressure, when it may be stripped from the mandrel, after which a fresh bar, &c., may be presented'to said mandrel, partly bent around the same, and the rolls G closed, when the coiling is repeated. Should it be desired to form a coil with the convolutions spread or separated, the lever N is operated so that as the coiling progresses the tapering nose P bears laterfect of which is evident on reference to Fig. 7.
The mandrel E is connected with the adjacent end of the shaft B by the bolts Q, which pass through the shoulder F into the shoulbe removed and substituted by a mandrel of a different diameter relatively to the varying sizes of coils required to be formed.
Various changes may be made in the deally against the coil or convolutions, the ef der F on said shaft, and said mandrel may tails of construction without departing from the general spirit of my invention, and I do not, therefore, desire to be limited in each case to the same.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. In a coiling-machine, a former consisting of a mandrel, a shoulder thereon, rolls surrounding the mandrel with their peripheries adjacent to the side of said shoulder, said mandrel, rolls and shoulder constituting the former of the machine and cooperating in conjunction with each other, and unitary means for moving said rolls toward each other and yieldingly engaging the shafts of said rolls and holding them in theirclosed position.
2. In a coiling-machine, a former consisting of a mandrel, a shoulder thereon, rolls surrounding the mandrel with their periphcries adjacent to the side of said shoulder, said mandrel, rolls and shoulder constituting the former of the machine and cooperating in conjunction with each other, the shafts of the roll being mounted in bearings, the openings of which are elongated radially with relation to said mandrel, a belt engaging the shafts of all of said rolls, and means for actuating said belt to move said shafts and rolls.
3. In a coiling-machine, forming mechanism, rotatable shafts carrying the same and surrounding the mandrel, and unitary means yieldingly engaging certain of said shafts for ism, consisting ofa mandrel, a shoulder thereon, rolls surrounding said mandrel adjacent to said shoulder and cooperating therewith, rotatable shafts carrying said mandrel and rolls, said mandrel being detachably secured to its carrying-shaft adjacent its shoulder, a belt engaging the shafts of all of said rolls, and means operatively connected with said belt for simultaneously moving the rolls and their shafts radially with respect to the mandrel.
6. In a coiling-machine,coiling mechanism, a 'movably-supported lever and a tapering nose on said lever adapted to be entered between and bear against and regulate the spread of the convolutions of a coil.
7. In a coiling-machine, a mandrel having a shoulder, rolls disposed about said mandrel with their shafts in elongated bearings, and a belt common to all of said rolls engaging the shafts thereof for simultaneously moving them radially toward and fromeach other and the mandrel.
8. In a coiling-machine, a mandrel, shafts mounted in enlarged bearings, rolls carried by said shafts, pulleys on said shafts, and means engaging all of said pulleys and connected with means for adjustment whereby all of said rolls maybe simultaneously moved toward and from the mandrel.
9. In a coiling-machine, a mandrel, a housing,elongated openings in said housi-ng,shafts mounted in said openings, rolls carried by said shafts, means connected with said shafts whereby all of the said rolls may be simultaneously moved toward and from the mandrel, and screws mounted on said housing opposite to said shafts and in alinement with said enlarged openings.
