APPARATUS FOR STRAIGHTENING AND COOLING METAL RODS.

SPECIFICATION forming part of Letters Patent No. 585,262, dated June 29, 1897.

Application tiled May 4, 1896.

To all whom it may concern:

Be it known that I, Vieron E. EDWARDS, a citizen of the United States, residing at Vorcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Improvement in an Apparatus for Straightening and Cooling Metal Rods, of which the following is a specification, accompanied by drawings forming a part of the same, in which- Figure 1 represents a plan view of the apparatus embodying my invention. Fig.' 2 is aside elevation of the same. Fig. 3 is a plan view, on a larger scale, of a portion of the cooling-table and of the adjustable carriage provided with gripping mechanism by which one end of the rod is held. Fig. 4 is a side view of the adjustable carriage and gripping mechanism. Fig. 5 is a end view of the adjustable carriage and gripping mechanism, showing the cooling-bed in transverse sectional view. Fig. 6 isatop view of the mechanism for applying a strain to the rod for the purpose of straightening the same. Fig. 7 is a side elevation of the apparatus shown in plan view in Fig. 6.' Fig. 8 is a vertical sectional view of the gripping mechanism shown on line 8 8, Fig. 6. Fig. 9 is a detached view of the mechanism for counterbalancing the weight of the gripping mechanism and parallel bars by which the same is supported, a portion being shown in sectional View in order to show the inclosed spiral spring. Fig. 10 is a top view of a portion of the cooling-bed, showing the inclined skids upon which the rods are held during the process of cooling, together with the rocking shafts and radial arms which are adapted to hold the rods at different positions upon the inclined skids. Fig. 1l is an end view of the parts represented in Fig. 10, and Fig. 12 is a detached view of the mechanism for actuating the rocking shafts and releasing the rods.

Similar numerals refer to similar parts in the different figures.

My invention relates to certain improvements in an apparatus for straightening rods while in a heated condition as delivered from the finishing-rolls of a rolling-mill and sup porting the same after they have been Serial No. 590,126; (Noinodel.)

straightened and during the process of cooling; and it consists in the construction and arrangement of the several parts, as hereinafter described, and set forth in the annexed claims.

Referring to the drawings, l, Fig. l, denotes a pair of inishing-rolls from which the rod is delivered,said rolls being in alinement with the trough 2, into which the rod is projected by the action of the rolls l. The trough 2 is shown in cross-section in Figs. 5 and 1l .and is provided with an angular bottom 3, provided with openings 4t, to allow the scale from the cooling-rod to fall, and having the vertical side Walls 5 5, between which the forward movement of the rod is restrained.

At intervals along the trough 2 are angular feed-rolls 6, having their periphery eX- tending slightly above the bottom of the trough and mounted upon the spindles 7, which are journaled in suitable bearings and carry sprocket-wheels 8, by 4means of `which the feed-rolls 6 are positively rotated by a chain-belt connection with the finishing-rolls 1 or other source of power. At one side of the trough is an inclined plate 9, preferably integral with the trough 2 and provided with a series of ratchet-teeth lO. Supported above the inclined plate 9 is a movable carriage 11, provided on one side with the trucks l2 12, adapted to run along one of the vertical side walls 5. llhe `opposite side of the carriage is provided with a shoe 13, resting on and adapted to slide along upon the ratchet-teeth l0.

Pivotally mounted upon the carriage l1 is a tilting frame 14C, having one end provided with a hook l5, adapted to engage the ratchetteeth lO, and in the opposite end ot' the tilting frame I place a rocking spindle 16 to which is attached the radial finger 17, having its lower end pointed at 18, said radial linger being of the proper length to engage the en d of the rod 19, resting upon the web 2O of the tilting frame 14. To the end of the rocking spindle 16 I attach a hand-lever 2l, extending rearward and parallel with the hooked end 15 of the tilting frame. The hooked end 15 of the tilting frame is lifted out of engagement with the ratchet-teeth 'l0 by meansof a coiled torsional spring 22, sup- IOO ported b y the rigid framework of the carriage and having one end 23 extending over the tilting frame and connected thereto by means of a link 24, the tension of the coiled spring 23 bein g justsufcient to hold the hooked end 15 of the tilting frame normally disengaged from the ratchet-teeth 10.

The trough 2 is placed in an inclined position longitudinally, and at the lower end of the trough I place the mechanism for exerting a longitudinal strain upon the rod for the purpose of straightening it.

The straightening mechanism consists of a framework 25, upon which is mounted a steam or hydraulic cylinder 2G, containing a reciprocating piston connected by its piston-rod 27 with a lever 2S, pivoted at its lowerend to the frame 25 and carrying at its u-pper end a stud 29, upon which is mounted a sleeve 30, provided on one side with a lug 3l, to which is pivoted the parallel arms 32 32, and upon the opposite side of the sleeve is a radial arm 33, pivotally connected with a screw-threaded rod 34, carrying a piston 35 and inclosed in a barrel 3G, which is pivoted at 37 to the frame 25. Inclosed within the vbarrel 36 and above the piston 35 is a Spiral spring 38, with its tension exerted upon the piston 35 to press it downward, so the force of the spring 38 will act as a counterbalance to the weight of the parallel arms 32 32. 4

The free ends of the parallel arms 32 32'are pivotally connected with the gripping-block 39, in which is pivoted a spindle 40, carrying a finger 41, having its end pointed at 42 and adapted to engage a rod inserted between it and a table integral with the gripping-block 39. Tothe spindle 40 is attached a hand-lever 44, by which the spindle is rocked and the pointed end of the finger 41 carriedinto engagement with the end of the rod 45, resting upon a table 43, thereby holding the rod from longitudinal movement. The grippingblock 39 is pivotally connected to the outer ends of the parallel arms 32 32 and is provided with a vertically-depending wall 39, from one side of which projects the horizontal table 43, providing an open space upon one side and above the table, thereby allowing the rod which extends from the iinishin groll to the trough 2 to be entered between the table 43 and the radial finger 41 by the lateral movement of the gripping-block in bringing it into alinement with the trough 2, thereby allowing the rod to be incloscd within the gripping-block 39 while it isin motion. Steam or water under pressure is admitted to the cylinder 2G in the usual manner by the reciprocating movement of a valve-stein 46, which is moved by a hand-lever 47.

A rod is delivered from the finishing-rolls 1 and conducted into the trough 2. The movement of the rod up the inclined trough 2 is aided by the positively-driven feed-rolls (i. As the rod runs clear of the iinishing-rolls its motion is continued by the action of the positively-driven feed-rolls G until the last end of the rod is brought opposite the grippingblock 39, when the attendant moves the block 39 into alinement with the trough 2 and inclosing the rod. The hand-lever 44 is then raised, causing the rear end of the rod to be clamped between the pointed end 42 of the :n ger 4l and the table 43, thereby checking the longitudinal movement of the rod. The forward end of the rod is then seized by an attendant and inserted between the web 2O and the radial finger 17 of the carriage 11, which has been moved along in proper position to meet the advancing end ofthe rod. The hand-lever 21 is then depressed, causing the pointed end 18 of the finger 17 to engage the end 19 of the rod and clamp it between the pointed end of the finger and the web 20, the pressure upon the hand-lever at the same time rocking the tilting frame 14 against the tension of the coiled spring 22 and carrying its hooked end 15 into engagement with one of the ratchet-teeth 10, thereby holding thecarriage 1l from movement while the rod is being straightened. rlhe upper end of the rod being now held from longitudinal movement and the lower end of the rod being engaged by the gripping mechanism supported by the free ends of the parallel arms 32 32, steam is admitted to the cylinder 2G, thereby rocking the lever 23 and exerting a tensile strain upon the rod held in the grippii'lg-block 39. As a tensile strain is exerted upon the rod the parallel arms 32 32, which had been deilected to one side, as represented in Fig. 6, for the purpose of bringing the gripping-block 39 in alinement with the trough 2, will be drawn into a position parallel with a straight line at right angles with the axis of the stud 29, drawing the rod into a straight line extending from the gripping-block 39 to the point of engagement of the rod with the carriage 11, thereby drawing the rod out of the trough 2 and over the inclined plate 9. The rod which has been straightened by the tensile strain exerted by the stretching mechanism is then released from its gripping mechanism and allowed to rest upon the inclined plate 9, from which it is moved by its own weight upon a series of inclined skids 43, which form a continuation of the vinclined plane of the plate 9. Journaled beneath the inclined skids and at right angles thereto are the shafts 49, to which are attached radial arms 50 with their free ends projecting slightly above the upper surface of the skids when the shafts 49 are rock `l in proper position. Parallel with the shafts 49 are the short rocking shafts 5l, to which arms 52 are attached,connected by links 53 with one of the radial arms 50 upon each of the shafts 49 and having hand-levers 54, by which the shafts 51 are rocked and through the links 53 rocking the shafts 49, in order to carry the radial arms 50 above the upper surface of the inclined skids or depress them below the surface ofthe skids. 'lheradial arms 50 serve as dogs to hold the rods which have been dropped upon the inclined table 9 from moving down the skids, and these dogs are arranged at different positions throughout the length of the skids, so as to hold the rods in groups, with a few rods in each group, during the process of cooling, the first series of dogs stopping the rods near the upper end of the skids until a number of rods have accumulated, when the upper row of dogs are depressed and the rods held by them are allowed to move down the inclined skids and be caught by the next series of dogs, the iirst series of dogs being again raised into position to hold the next group of rods. lVhen the second group of rods have been accumulated, the first group held by the second series of dogs is released and allowed to move down to the third series of dogs andthe second series of dogs brought into position to receive the last-accumulated group of rods as they are released by the Iirst series of dogs. The rods are thus held for a period of time at different stages of their movement over the inclined skids and before they are finally released in a cooled state upon the horizontal table at the foot .of the inclined skids, from which they are transferred to a series of positively-rotated rolls 5G, by which they are moved endwise to suitable shearing apparatus 57, where they are cut into the desired lengths and delivered upon the table 5S.

The trough 2 is provided with an angular bottom in its cross-section in order to cause the rod to move in the center of the trough during its longitudinal movement and also to allow it to be drawn laterally out of the trough by the application of a tensile strain between the clamped ends of the rod, which are outside the plane of the trough. A curvature is given to the trough 2 corresponding to the catenary curve assumed by the rod as it is suspended between the clamping mechanisms in order to cause the rod to clear the Vtrough throughout its length.
