c'ooLiNc-BED FOfR BAND-IRON;

srncirrcnrron forming part of Letters Patent No. 614,202, dated November 15, 189%.

Application filed July 26, 1897.

To all whom it may concern:

Be it known that I, VICTOR E. EDWARDS, a citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented a new. and useful Improvement in Cooling-Beds for Band-Iron, of which the following is a specification, accompanied by drawings forming a part of the same, in which- Figure 1 represents a side elevation of a cooling-bed for band-iron embodying my invention; and Fig. 2 is avertical sectional view on line 2 2, Fig. 1.

Similar letters refer to similar parts in both figures.

My present invention relates to an apparatus for cutting a continuous strip of bandiron while it is being delivered from the reducing-rolls into determinate lengths while still in motion, straightening the severed pieces, bringing their ends against a stopplate, and conveying the strips to a' common pile or receptacle, said apparatus'being capable of acting upon the strips of band-iron while they are still in motion, thereby en- I abling the operations to be carriedon during the process of cooling; and these objects are accomplished by means of the mechanism shown in the accompanying drawings and hereinafter described, the several features of novelty being specifically set forth in the annexed claims.

Referring to the drawings, A A denote a pair of feed-rolls by which a strip of bandiron B as delivered from the last pair of reducing-rolls is fed forward at a speed independently of the speed of the reducing-rolls. Shear-blades A A are inserted in the periphery of the rolls A A parallel with their axes and arranged to act conjointly in severing the band-iron as the rolls are rotated in the direction of the arrows 1 1, severing the bandiron once during each revolution of the rolls A A into lengths equal to the periphery of the rolls. The peripheries of the rolls A A are concentric with their axes of rotation and are arranged to run in contact with the strip of band-iron, so that the rolls A A are primarily feed-rolls, thereby imparting a momentum to the strip of band-iron. The momentum of the severed pieces is sufficient to carry them Serial a. 646,052. (No model.)

forward through a guide-trough 0 upon a cooling-bed 0, having its upper surface 0 inclined and located slightly below the guide trough C, so that the band-iron as it passes out of the guide-trough 0 upon the inclined surface 0 is bent downwardly by its own weight, as represented at B, Fig. 1. Recessed in the cooling-bed O is a semicircular rocking shaft D, having its plane side D 00- 6o incident with the inclined surface 0 at one end by its rocking motion, but being slightly raised above the inclined surface C at the opposite end of its rocking motion, as represented in Fig. 2, that portion of the curved periphery of the shaft D which is raised above the inclined surface 0 forming a stop to prevent the band-iron from sliding down the inclined surface 0 The side of the rock in g shaft B which forms the stop for the bandiron is located at a lower point upon the inclined surface 0 than the guide-trough C, so the heated band-iron becomes deflected in the direction of its width, as shown at B Fig. 2.

The severed strips of band-iron are straight- 7 5 ened by their contact with the inclined surface 0 and by the side of the rocking shaft D. At the end of the cooling-bed O opposite the guide-trough C is a stop-plate E, against which the successive pieces are brought in order to even their ends. As the heated and flexible pieces of band -iron' are projected upon the inclined surface 0 with considerable velocity it becomes necessary to retard their advance movement in order to prevent them from being carried forcibly against the stop-plate E, which would cause the strip of band-iron to bend or buckle.

framework of the machine and connected by a link F with a crank-pin F which is adjustable in a slotted face-plate F carried on the shaft of the upper feed roll A. The

brake-shoe affords sufficient frictional resist- 5 ance to retard the forward movement of the severed strip 13 but not enough to entirely check its motion. As the last end of the sev- This is accofir- 'plished by means of a brake-shoe F, carried by a two-armed lever F, pivoted to the rigid o I supported upon the peripheries of a series of conical feed-rolls G, which project through openings G in the inclined surface 0 The rolls G rotate in the direction of the arrows 2, Fig. 1, in order to move the strips of bandiron forward against the stop-plate E. The rolls G are conical, so that the forward or feeding motion of the strips becomes gradually reduced in speed as they approach the lower ends of the rolls in order that they may not be carried violently against the stop-plate E. Each strip of band-iron as it slides off the rolls G is delivered upon an endless apron H, carried upon rolls H H, having parallel axes. The apron H throughout the upper portion of its travel is supported upon a platform I in order to maintain the apron in a horizontal plane. The shaft D is rocked by means of an arm J projecting from one end of the shaft and operatively connected by means of links J J and a walking-beam J with a crank-pin J adj ustably held in a slotted face-plate J attached to the shaft of the lower feed-rolls A I do not, however, confine myself to the specific mechanism shown for imparting a rocking motion to the brakeshoe F or the rocking shaft D.

The operation of the apparatus above described is as follows: A continuous strip of heated band-iron as delivered from the reducing-rolls is conducted between the revolving feed-rolls A A, by which it is projected forward through the guide-trough O and is severed at each revolution of the rolls A A by means of the shear-blades A The momentum of the strip after it has been severed by the shear-blades is sufficient to carry it forward upon the inclined surface 0, its flexibility allowing its weight to carry it downward into the corner formed by the inclined surface 0 and the raised edge of the semicir- ..,cu :tirocking shaft D, causing the heated rocked to allow the severed strip to slide down the inclined surface and be supported by the periphery of the conical rolls G, which are rotated by connected driving mechanism to move the strip forward toward the stopplate E with a gradually-retarded movement as the band-iron approaches the smaller end of the conical rolls, from which it is carried forward by the apron II and delivered upon a common pile or into a receptacle.
