' 7 To all whom it may concern:

Be it known that I, Jones REMMEN, a resident of Donora, in -the county of Washington and. State of Pennsylvama, have 1n+ vented a new and useful Improvement in. Wire and Rod Coiling and Coolmg Devices,

of which the following is a specification.

This invention relates to ap aratus for coiling and cooling wire, rods or wire, or

product.

other small metal rodsor bars and similar The object of the invention is to provide a coiling and cooling device whereby the wire, rod or other product is coiled un formly and with certainty and whereby 1t 1s cooled below the point of oxidation, so'as to prevent scale formation.

The invention comprises, generally stated,

a coiling device of vertical conical form,-

having the guide for delivering the product to be coiled located vertically above the same, together with means for rotating sa1d conical coiling device.

The invention also comprises a coiling device of the character specified mounted on trunnions so that it can be tilted to discharge the coil.

The invention also comprises a coiling devicev of the character specified arranged to coil the rod while submerged in water to cool the same. y

The invention also comprises certain details'of construction and arrangement hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a vertical section through the lower art of a wire rod press and my improved coi ing device; Fig. 2 is a side view of the same; and Fig. 3 is a sectional view showing a double coiling device arranged to receive wire rods from a rod mill.

-The invention is-particularly adapted for coiling rods for wire, and it will be described as applied to this use, but it will be understood that it is not limitedthereto, but is 3. The guide 4 for guiding the rod to the Specification of Letters Patent. Patented Oct, 19, 1909, Application filed. September 2a, 1905. sei l no. 4554822.

reel is located directly above the, cone, so that the forward travel of the rod causes it to automatically coil around the cone. Coiling devices of this general character with stationary cones are old, the rod being coiled automatically by its forward travel. In

'somecases the rods do not coil themselves uniformly on a stationary coiler of this kind.

In order to prevent kinking or reversing of the rod and secure a. uniform coiling there- -of, I provide such vertical conical reel with means for positively rotating the same on its vertical axis. The driving means shown comprises a vertical shaft 5 carrying a bevel gear 6 meshing with a similar gear 7 on a horizontal shaft 8 which may be driven any suitable way, such as by bevel gear 9 meshing with a similar gear on driving shaft '10. T1118 imparts positive rotary movement to the cone and effectually overcomes any tendency of the rod to buckle, kink or reverse its direction of coiling around the cone.

It is not material at what speed the cone-is driven, since if the speed of the cone is greater than the feeding travel of the rod, the latter simply follows around with the cone; whereas if the cone is driven slower than the feeding travel of the rod, the latter automatically coils itself in the same manner as though the cone were stationary. Consequently, this arrangement operates uniformly well, irrespective of the size of the 0011 or bundle on the cone, or ggf the rate of feed or travel of the rod.

The cone is mounted to discharge the coil or bundle. To this end the shaft 5 is mounted 1n a frame 12 provided with horizontal trunnions 13 mounted in suitable bearin l4: and provided with means for tilting t e frame. The means shown comprisesa pinrack bar 16 which may be actuated by any suitable mechanism, such as a hydraulic or k other power cylinder 17. Various other mechamsms for tilting-the reel to discharge the coil or bundle may be employed. The

shaft 8 extends out through one of the hollow trunmons of the frame, so that the drivmg means does not interfere with the tilting.

In order to discontinue the rotation of the I cone when tilted, I provide driving connections which become disengaged when the cone is tilted. As shown, the shaft 5 is provided virith a disk 20 having a beveled face engaging by friction a corresponding face 21 on the inside of the cone, thereby forming a frictional drivin connection which is in engagcment whent e cone is in upright or vertical position. The cone is loose on the shaft 5 so that when inverted, it slides on said shaft to break contact between 'the face 21 and disk 20. To prevent the cone from sliding off the shaft 5 and at the same time be free from the rotary action of said shaft, I provide a suitable stop, that shown comprising a disk or arms 22 secured to the frame 12 and having its outer edge arranged to be contacted by an inwardly projecting ring or flange 23 on the base of the cone. The flange is shown as a separate part from the cone, and the flange and disk 22 are provided with correspondingly inclined cont-acting faces, but these are details which can be varied within wide limits. The shaft 5 is mounted in a step bearing 2d in the frame 12.

In order to cool the-rod while coiling, the cone is surrounded by a suitable receptacle or basin. As shown the cone is provided with an outwardly projecting portion or floor 26} tothe outer edge of whlch is conpoint.

nected a ring or annular wall 27, forming in effect a basin surrounding the cone. This basin is water-tight and contains water to such depth that the rod is submerged while being coiled. The centrifugal force due to the rotation of th cone causes the water to assume an inclined position as shown at 28. The excess of water overflows the ring or wall 27. The water may besupplied from any suitable source, andmay be either-cooling water from the dies or rolls used to form the rod," or supplied through a separate source. v

Fig. 1 shows the rod produced by forcing the same by a suitable plunger 30 working in a cylinder 31 whose lower end is closed by die 32 through which the hot metal is forced to-form the rod. The die is cooled by having water supplied to a passage 33 therein,

which passage has connected thereto ports 34 in such position that the water is proj ected' against the rod as it emerges fromthe die, thus cooling the rod to some extent at this Below the die is a suitable tube or conduit, 35 forming the guide and having connected to its lower end a hood 36 covervo1; conduit 35 and into the coiler. If this water is not sufficient, additional water may be supplied through pipe 37 projecting through the hood 36; The rod formlng apparatus shown in Figs. 1 and 2 is substantially similar to that described and claimed in my application filed Aug. 17 1908, Serial No. 448.855.

Fig. 3 shows the application of the invention to an ordinary rod mill whose finishing air of rolls is shown at 40. From this eads a suitable tubular guide 41 for conducting the rod to the coiler, said guide at the same vertical sha t 5 so that when the frame is tilted to discharge the bundle from one of the cones, the other cone is brought into upri ht posltion to receive a fresh .rod. This dou ble coiler is particularly adapted for 'rod mills where rods are produced in rapid succession through the same ass.

In the use of the apparatus described, the

rod is formed either between the rolls shown in Fig. 3, or by pressing through a die as shown in Fig. 1. In either case the hot rod travels at a comparatively high speed. It is guided to the cone at a point directly above the latter, so that said rod tends to coil itself automatically around the cone, due to ,the

travel imparted thereto by its production. By driving the cone positively, however, the rod is prevented from snarling, kinking or reversing its travel around the cone. The driving of the cone does not interfere with the proper automatic coiling of the rod. With a high speed of rotation the rod travels around w1th the cone, whereas with a slow speed of rotation, the rod automatically coils itself partially in the same manner as though the cone were standing still. Even a moderate speed of rotation of the cone prevents all danger of reversing, snarling or kinkin and by having a cone shaped. coiler with t e delivery guide located above the same, no particular attention 'nee be paid to the speed of travel of the rod or the speed of rotation of the coiler, as it operates equally as well when the coil is being formed around the large part of the cone as when being .formed around a smaller diameter. WVhen the coiling of a bundle is completed the frame 12 is tilted on its trunnions to automatically discharge the bundle. When inverted the cone slides downwardly on the portance when forming small rods, such as,

for wire, in which even a thin layer of oxid constitutes a very perceptible percentage of the entire tonnage.

Apparatus for coiling wire, rods and similar product, comprising in combination, a cone-shaped receiver or reel arranged with its axis vertical, mechanism for rotating said receiver or reel, a guide for the product located above and in lme with the axis of said cone-shaped receiver or reel, and mechanism for feeding the product through said guide and to the receiver or reel.
