MACHINE FOR TREATING METAL STRIPS.

Specification of Letters Patent. Pate ted June 7, 1921.

Original application filed December 20, 1917, Serial No. 208,070. Divided and this application filed March 3, 1920. Serial No. 362,899.

To all whom it may concern:

Be it known that I, AUGUs'r SUNDH, a citizen of the United States, and a resident of Hastings-upon-Hudson, county of Westchester, State of New York, have invented certain new and useful Improvements in to be treated and a part of the means for pickling the strips,

Figs. 3, 4 and. 5 show in section and plan the stripsplicing operation; I

Fig. 6 is an elevation of the pickling means;

Machines for Treating Metal Strips, of Fig. 7 is a fragmentary plan of a portion 60 which the following is a specification. of the apparatus of Fig. 6;

This invention broadly considered has ref- Fig. 8 is an enlarged section of the 10 erence to the treating of metal strips, wheremeans for holding the parts of the pickling by strips as they come from the annealing means in adjusted position, and oven are pickled, cleaned, dried and straight- 'Fig. 9 is a wiring diagram. 65

ened and finally wound up into rolls in a thoroughly cleaned condition.

It is desirable in such a machine to provide means whereby several strips may be treated simultaneously, and to accomplish this end I provide a plurality of winding drums which are capable of drawing a plurality of strips through the machine simultaneously, and inasmuch as the various treating means making up the machine have been provided with this idea in mind, it is possible to stop any one of the winding drums without stopping work on the other strips. For the same reason I have provided the guides for the strips, which guide the strips in their passage, independently operable.

The present application is a division of my copending application, Serial No. 208,070, filed December 20, 1917, and is di rected specifically to that portion of the machine whereby successive strips passing through the same may be spliced to each other readily, and wherein the strips are pickled, it being understood that a number of strips may be treated simultaneously, and as the rear end of each strip is reached, it is stopped without disturbing the others, and another strip spliced or joined to it, this last strip then being drawn through the machine and treated. s heretofore mentioned the whole machine is so constructed as to make this possible.

Referring now to the drawings wherein I have illustrated an embodiment of my invention,

Figure 1 shows in elevation a machine embodying the novel features making up my invention;

Fig. 2 shows in part sectional elevation the means provided for splicing the strips together, the holders for the coils of strips In order that a thorough understanding may be had of my invention I will describe briefly the entire machine as illustrated in Fig. 1, describing the details of construction illustrated in the other figures later on.

The strips are placed in a coil on the machine at B, from which the endof a strip, or all of the strips if more than one is being treated simultaneously, is ledthrough a pickling reservoir where the strip is subjected to a pickling operation. The strip next passes to D where it is washed and scrubbed and freed of dirt and scale, next passing to E. Here the strip is dried and straightened, next passing to winding drums designated F where the strip is wound u in a thoroughly cleaned condition. It is understood that as many strips may be treated simultaneously as may be desired, the number to be treated being limited only by the'space available for installation of the machine. I have shown three strips being treated.

AtB, I have provided a number of holders for the supply of metal strips, these holders being in the form of slots 1, as many as may be desirable, drels or the like on which the metal coils 2 are placed. The frames in which the slots 1 are formed are mounted on a bed3, and adjacent an end of a pickling reservoir 4;.

"adapted to receive man This reservoir as it contains apickling acid is preferably lead lined throughout to withthe carriers are strip-guiding sectional rollers 8, supported in the carriers by rods 9 of brass or other non-corrosive material, the rollers themselves being preferably made of porcelain. By rotating thehand wheels 7 to the left or right as the case may be the rollers 8 and carriers 5 may be raised and lowered.

In-order that the hand wheels may be locked, I have provided plates 10 one for each Wheel,-adapted to be brought into and out of engagement with the wheel by a hand wheel 11 mounted on a stub shaft 12 having a screw-threaded connection with the side of the pickle reservoir.

vThe strips are passed from the supply coils over a sectional roller 13 at the end of the pickle reservoir, and from thence they pass under. the upper sectional rollers 8, at the left hand end of the reservoir, through the pickle in the reservoir over sectional rollers 8 at the right hand end of the reservoir, back through the pickle, around the lower set of sectional rollers 8, and back through the pickle once more to the right hand end'of the reservoir. From these rollers the strips are led at an incline upwardly betweeen wipers 13 at the end of the reservoir, around sectional rollers 14, from which they pass through the remaining portions D andof the machine andare wound on the drums or blocks at F.

It will be seen that the rollers 8 in the reservoir are so disposed that each strip is caused to pass through the pickle several times soas to be thoroughly pickled. Inasmuch as the rollers 8 are mounted on the carriers 5 it will be seen that these carriers high as 80% may be obtained in this man- In order that it may not be necessary for' the operator to place his hands in the pickle at any time I have rovided the hand wheels 7, rotation of whlch will raise the strips passing through the reservoir out of the pickle, the hand wheels then being locked by the mechanism already described until it is desired to resume operations.

In order that the contents of the pickle reservoir may be heated which I have found desirable, I provide steam pipes 15 of some non-corrosive materialsuch as l ead.

As it isusually desirable to coil the finished strips in greater lengths than they come to the mac 'ine, I have provided the splicing mechanism already briefly-referred In and fln io'mn'hafl A. This mechanism" nnmprises a frame 16, carrying a punch head 17 adapted to be reciprocated vertically by a foot pedal 18. As many of these punch heads are provided as" there are strips to be spliced to a strip passing through the machine, from which figure it will be observed that the end of the coil of new strip is led from the strip holder passed around the roller 21 and passed under the rear end of the strip already in the machine. It will be-understood of course that the strip in the machine must be at rest at this time, and I will explain presently how this is acc0mplished without stopping the operation of the entire machine. The pedal 18 is now depressed to punch three holes through the strip as indicated at 22 in Fig. 5. The strip is then passed to the anvil 23 and hammered down .to the form indicated in Fig. 4. It will be observed that the finished splice has no sharp edges to catch in the machine as the strips passthrough, which is of importance as heretofore much trouble has been experienced from the strips catching.

The wiring diagram for the machine is shown in Fig.' 9, and it will be seen from this figure that the motor 24: for driving the winding drums together with the motors 25 and '26 for the straightening and drying apparatus and the washing and scrubbing apparatus all receive their power from a common source 27, each motor being independently controllable by switches 28 or centrally controllable by a switch 29. The m0- tor 24 for the winding drums is connected to each drum by independently operable clutch mechanism 30 controlled by a bank of push buttons 31, so that each drum may be started and stopped independently of the others in order that the splicing operation may be erformed without-effecting operation on t e other strips passing through the machine. a
