TRANSFER MEGHANISM FOR LAP-WELD TUBING.

Application filed January 29, 1915.

Y fo all 'zu/0m t may concern.'

Be it known that I, DANIEL lVoon` SIDE, a citizen of the United States, residing at Youngstown, in the county of Maliening and State of Ohio, have invented new and useful Improvementsin Transfer Mechanism for Lap-Weld Tubing, of whichV the following is a specification.

My invention relates to mechanism for Ytransferring lap-weld tubing sidewise from one welding-trough over an adjacent welding-trough. v

It is the object of my invention to provide a simple mechanism by which tubing in one of two parallel troughs at the rear end of a lap-weld furnace may he transferred sidewise over the other welding-trough. Heretofore it has been common to provide arms for lifting the tubes out of one trough and carrying them over the other trough. I have simplified the mechanism-by bodily lifting or swinging one welding-trough with a tube thereon over the other weldingtrough.

My invention further consists in details of the mechanism whereby the troughs are supported and operated.

Referring to the accompanying drawings, Figure 1 is a plan of one end of a pair of welding-troughs equipped with my invention; Fig. 2, a cross-section on the line Hull, Fig. 1; Fig. 3, a side elevation of a second form of my invention with parts broken away; Fig. e, a cross-section on the line ITL-IV, Fig. 3; Fig. 5, a cross-section on the line v V, Fig. 3; and Fig. 6, a cross-section on a reduced scale on the line VI-VI, Fig. 3.

Referring first to Figs. 1 and 2, 1 and 2 represent a pair of welding-troughs for re ceiving pipes as they are dischargedV from the welding rolls situated at the rear end of a. lap-weld furnace. I have not illustrated the furnace and rolls as they are well known in connection with pairs of weldingtroughs located as above described. The weldingtrough 1 normally rests on the top of pillars near the ends of the trough, one pillar 3 being shown. The trough is secured to the rock-shaft l which is parallel with the trough and supported by the pillars 3. To one side of the trough 1 I pivotally connect Vone end of the tilting skids 5, which have Specification of Letters Patent.

Serial No. 5,109.

.lVhen it is desired to transfer the pipe 11 from the trough 1 to the skids, the motor 10 is operated to cause the trough 1 to move from its full-line position to its dotted position (Fig. 2), whereupon the pipe 11 rolls out of the troughV 1, as shown on Fig. 2, and down the skids 5 to the skids 6, on which a pipe 12 is shown. The welding-trough 2 1s arranged at that side of the trough 2 which is opposite the skids 5. Its ends are supported by the legs 13, having the curved arms 14 connected to the rock-shaft 15. These arms 14 have their curves extending downwardly from the troughs and then upwardly in the form of the letter U, one leg of the U bearing the trough and the other being connected to the shaft 15. The curves are so shaped that the trough 1 is in the same when'the trough 2 is swung up on the shaft 15 to the dotted position.(Fig. 2). The shaft 15 is provided with the arm 16 having its outer end pivoted to the links 17, to which the piston rod 18 of the hydraulic or other motor 19 is pivoted.

Referring now to Figs. 3 to 6, the parts thereon corresponding in function to parts on Figs. 1 and 2 have the same reference numerals as on Figs. 1 and 2 with the eX- ponent letter a. The rock-shaft 15n has its ends mounted in the housings 20 and is provided with the collar 21 keyed thereon. The collar has the opposite arms 16a and 16", the former being connected by the links 17 to the pistonerod or plunger 1Sat of the motor 19a, and the latter being connected by the links 17b to the piston-rod or plunger 18b of the motor 19h. To the shaft 15a are keyed Vthe collars 22 which carry the arms 14a, supporting at their outer ends the legs 13a. The trough 2n is supported on the top of these legs, which rest normally on the block 23 on the bed 24: of the apparatus. The rock-shaft la is secured to the trough 1au which is between the shaft 4 and the trough 2, To the arm 7a on the shaft 4a, carried by the bearings 29, I secure the upper end of the links 8a, the lower end of the links being connected to the arm 25 on the collar 26 which is loosely mounted on the shaft 15a. This collar carries the opposite arms 27 and 28, the former being linked to the piston rod or plunger' 9a of the motor 10 and the latter being linked to the piston-rod or plung'er 9b of the motor 10b. When it is desired to discharge a pipe in the trough l2L upon the skids 6a (only one shown) the motor 10a is operated which causes the plunger 9ZL to oscillate on the sha-ft 15a toward the right, thereby lifting the arm 25, the links 8a and the arm 7u. The lifting of the arm 7 oscillates the shaft 4 so as to cause the trough 1a to be swung up over the shaft on the dotted lines above the same (F ig. 4) and to discharge the pipe therein upon the said skids. The trough is returned to its normal position by the motor l()h through the plunger 9b, the arm 28, the collar 26, the arm 25, the links 8, the arm 7a, and the shaft 4a. When it is desired to discharge a pipe in the trough 2a upon the skids 6a, the motor 19n is operated, causing the plunger 18, the links 17a, and the arm 16a to rise. The upward movement of the arm lba oscillates the shaft l5 toward the left, `thereby causing the collars 22 keyed on the shaft to lift the arms 14 together with the legs 13a and the trough 21% The latter moves up on the dotted lines (Fig. Ll) on an arc having its center on the shaft l5, the radius of this arc being sufficiently long to allowy the trough 2a to pass over the trough ln and discharge a pipe therein upon the' skids 6a in the same manner that the trough 2 passes over the troughl and discharges the pipe 11 therein upon the skids 6;; The trough 2a is returned to` normal position by the motor f trough so as to pass over the second ltrough.

and discharge a pipe therein on the opposite side of the second trough.

2. A pair of welding-troughs arranged side by side, a receiving table arranged at the outer side of one trough, means for-tilting the said trough and discharging a pipe in the said trough upon the table, and means movable relatively to the said trough` for lifting the other trough over Ithe said tilting trough and discharging a pipe in the second trough upon the table.

Signed at Youngstown, Ohio, this 26th day of January 1915.
