BAR-PILING MECHANISM.

SPECIFICATION forming part of Letterslatent No. 610,749, dated September 13, 1898.

Application filed April 22, 1898. Serial No. 678,471. (No model.)

State of Ohio, have invented or discovered certain new and useful Improvements in Bar- Piling Mechanism, of which improvements the following -is a specification.

The invention described herein :relates to certain improvements in barpiling mechanism.

It is now the general practice to arrange bars as they come from the cutting mechanism and while in a hot condition in a pile one upon the other. This arrangement of the hot bars prevents to a very considerable extent the oxidation of the surfaces of the bars. The barpiling mechanism now in general use is so constructed and arranged with reference to the delivering-table of the cutting mechanism that the bars are`slid longitudinally upon preceding bars. As the present mill practice requires a rapid movement of `the bars, the latter are moved with considerable velocity, so that when they are stopped by the abutment at the rear end of the pilingframe the forward ends of the bars, which are hot, are buckled and bent. This bending or buckling prevents the bars from lying compactly or closely one upon the other and therefore permits of the access of air and the consequent oxidation of the surfaces.

The object of the presentinvention is to provide for the straightening of the bent or buckled portions of the bars and also to provide for the easy removal of a pile of bars.

In the accompanying drawings, forming a part of this specification, Figure 1 is a top plan view of a bar-piling mechanism constructed in accordance with my invention. Fig. 2 is a view partly in side and partly in end elevation of the same. Fig. 3 is a transverse section, the plane of section being indicated by the line III III, Fig. 1. Fig. 4 is a side elevation of a po'rtionof a form of bar-piling mechanism having my improved straightening mechanism applied thereto. Fig. 5 is a sectional elevation of the same, showing the position of the parts when the receiving cage or frame is raised; and Fig. 6 is a front elevation of the straightening mechanism.

At the end of the feed-table A leading from the shear mechanism are arranged a pair of rolls l, one or both of which are positively driven, and the upper roll is forced downwardly by springs 2, so as to obtain a firm grip by the rolls on the bar. The employment of a pair of gripping-rolls at this point is desirable, as the frictional resistance presented by the bar sliding over the surface of the preceding bar is considerable, so that at times the frictional grip of the ordinary feedrollers on which the article rests would not be sufficient to effect a movement of the bar. In the rear of the feed-rollers 1 and at suitable distances therefrom I arrange one or more rails 3 at right angles to the path of movement of the article as fed by the rollers 1, and on these rolls I place the wheels 4 of the trucks 5. On these trucks are secured supporting frames or beds 6 and 6, carrying the cages or frames for the bars. The cages or frames are formed by bottom plates 7 7 and side plates 9 and 9a. The bottom plates may be made continuous, if desired; but it is preferred to form them in sections, as shown, the forward end of each section being downwardly curved, so that they will not present any obstruction to the onward movement of Vthe bars.

` A series of posts or standards 8 and Sa are secured to opposite sides of the beds and 6a and project above the bottom plates 7 and 7a. The side plates 9 and 9 are secured to these standards above the bed-plates and serve to laterally ret'ain the bars in position. In order that the forward ends of these side plates may not present any obstacle to the onward movement of the bars, they are curved outwardly, as shown in Fig. 1. These receiving cages or frames can be shifted laterally into and out of line with the feed-rollers 1 by any suitable form or constructionof mechanismsuch, for example, as that shown, consisting of iiuid - pressure cylinders 10 and 10, arranged on opposite `sides of the cages or frames and having their piston-rods'or rams connected to thefralnes, as shown;A `In such a construction one of the cages or frames after having received a sufficient number of bars can be shifted out of line of feed of the rollers 1 and the other framesimultaneously IOO shifted into receiving position. While the second frame or cage is being charged the pile of bars can be removed from the other frame by a crane or any other suitable means. An abutment 12 is arranged in the line of feed of the bars as they come from the feed-rollers 1 to serve as a stop to the onward movement of the bars. As hereinbefore stated, the bars are moved with such velocity into the cages or frames that their forward ends are buckled up by strikingagainst the stop or abutment 12, so that they will not lie closely against or upon the preceding bar, and the succeeding bar will be raised in similar manner. In order to flatten out the ends of the bars and cause them to lie closely one upon the other, a power-driven hammer is so arranged with relation to the stop 12 that the ends of the bars when buckled can be easily and quickly hammered down to form a close compact pile.

In the construction shown in Figs. 1 and 2 the stop or abutment 12 is formed by a standard or upright 13, secured upon a suitable j foundation in proper relation to the rear ends of the cages when in the line of feed of the rollers `1. A fluid-pressure cylinder 14 is secured to the upper end of the post or standard, so that its axis will be in line with the rear ends of the bars as they abut against the stop 12. To the piston of this fluid-pressure cylinder is secured a suitably-shaped head 15. It will be readily understood that by the operation of the piston with its hammer-head the ends of the bars may be quickly and easily hammered down straight.

As shown in Figs. 4, 5, and G, myimproved straightening mechanism can be applied to a form of bar-piling mechanism now in use. Generally stated, this bar-piling mechanism consists of a frame 17, supported upon the rams or piston-rods of Huid-pressure cylinders 18, whereby the frame can be raised and lowered as required. This frame is formed by a series of vertical standards 19, which have side plates secured thereto for the purpose of laterally retaining the bars in position. The cage or frame thus constructed is designed to be lowered to receive the bars from the feed-rollers 1 and when a sufficient number has been charged thereinto to be raised for the removal of the bar-piles, which are held in position by stops 21, mounted upon the guide-standards 22.

At the rear end of the cage or frame a stop or abutment is formed by a bracket 23, pivotally mounted in suitable bearings formed on the post or standard 24. On its front side this bracket is provided with a toe or projection 25, adapted to project under the rear end of the cage or frame, which serves to hold the bracket in a vertical or operative position. The bracket is turned backward when the cage or frame is raised by means of a weight 26, connected to a rearward projection 27 on the bracket. A hammer-head orplate 28 is secured to the upper end of bars 29, which pass through suitable guide-arms 30, secured end loosely connected to the base of the frame or standard. This lever is connected at a point midway between its ends to the rod 33, which has its ends connected to the pistons of fluid- pressure cylinders 34 and 34, which are formed integrally with or secured upon the frame or standard 24. As the bars are forced against the stop 12a formed by the upper ends of the bracket their buckled or bent ends can be straightened by the operation of the hammer-head 28. As soon as the cage or frame has been charged with the proper number of bars it is raised, so that the pile can be removed, as hereinbefore stated. As the cage or frame is raised the bracket and the hammer-head will be moved by the weight 26 out of the line of movement of the rear ends of the bars. As the frame is lowered to operative or receiving position its rear end will strike against the toe or projection 25 on the bracket, thereby returning the bracket and the hammer-head to operative position.

I claim herein as my invention- 1. The combination of a bar-piling mechanism and a striking or pressing mechanism arranged in such relation to the bar-piling mechanism as to be operative to straighten and Hatten down bars fed into the piling mechanism, substantially as set forth.

2. The combination of a bar-piling mechanism, a striking or pressing mechanism arranged in operative relation to the piling mechanism, and means for shifting one of said mechanisms, substantially as set forth.

3. The combination of one or more bar-receiving cages or frames, means for shifting the same, and a striking or vpressing mechanism arranged in operative relation to the receiving cages or frames when in normal position, substantially as set forth.

4. The combination of a bar-receiving cage or frame, means for shifting the cage or frame, a striking or pressing mechanism and means controlled by the cage or frame for shifting the striking or pressing mechanism out of operative position, substantially as set forth.

5. The combination of abar-receiving cage or frame, means for raising and lowering the cage or frame, a pivotally-mounted bracket provided with a toe projecting under the rear end of the cage or frame and adapted to automatically drop away from the frame, a striking or pressing head movably mounted on the bracket, an operating-motor and a flexible connection from the motor to the striking or pressing head, substantially as set forth.

In testimony whereof I have hereunto set my hand.
