Nov. 25, 1947. A. F. WELLS, JR., .ET AL APPARATUS FOR FORMING TEST SAMPLES OF ELECTROLYTIC TIN PLATE Filed Nov. 13, 1945 /N VEN TORS Tiq.. I
P/M CWc/QB A TTORNE);
of the lower arm of the frame below the path of the strip so that when the latter overlies the die and the punch descends, a circular sample will be struck from the strip. For conveniently receiving this sample a tube 20 having an inwardly directed flange 20 at its lower end is mounted below and in alignment with the hole in the die block so that as the sample descends therefrom it will pass into the tube, and to enable it to be conveniently removed therefrom the tube is cut away to provide a slot 2| in its front so the thumb and finger of the operator can be nserted and the sample or samples turned edgewise and drawn out through the slot, or the tube may be arranged in some other manner for ready removal of the samples.
For actuating the piston compressed air or other suitable fluid is conveyed to the respective ends of the cylinder by pipes 22 controlled by a valve or valves (not shown) positioned for convenient access by the operator who normally stands near that edge of the strip opposite that proximate the apparatus when retracted to the non-operative position of Fig. 3 and which for convenience we term the front edge.
It will now be apparent that when the punch is raised the frame can be moved forward on tracks I from the position of Fig. 3 so as to enter the rear edge of the strip in its throat and then bring the punch above the strip to any desired point between its edges. To facilitate entry of the strip between the punch and the die block, a forwardly and upwardly curved shield or guide 24 provided with an opening for the passage of the punch is secured to the front end of the upper bar of the frame so as to properl guide the edge of the strip into the throat of the latter.
Since it is desirable that the samples used for making each consecutive test be cut from the strip at the same distance from its edges, means now to be described are provided for effecting this result by insuring the same relative location of the punch with respect to the rear edge of the strip each time that it is operated to form corresponding samples whereby all those taken proximate the rear edge of the strip will be centered on a line parallel thereto, all those from the center of the strip on a line coincident therewith, and all those proximate the front edge on a line likewise parallel to the rear edge. T this end a pair of brackets 25, 26 are fixed to the upper frame arm 2, conveniently to one of its sides, and serve to rotatably support a rod 21 substantially parallel to but extending transversely of the upper surface of the strip. The front end of this rod, which is long enough to extend well across the strip, is formed to provide a convenient handle 28 while a nut 29 on the rod behind bracket 26 is effective to communicate a pull on the rod to the frame to move it forward on the tracks. Additionally means are provided for stopping such forward movement of the frame at consecutive predetermined intervals with respect to the rear edge of the strip so that the initial movement from the position of Fig. 3 will bring the punch a predetermined distance from that edge preparatory to punching out the first sample, the ensuing movement will bring it to the center of the strip, and the final movement to a point relatively close to the front edge thereof; thus after the first sample is punched out the apparatus may be moved to the second position and properly located therein preparatory to punching the center sample and then to the third position preparatory to punching the other eds? Sample,
, ter sample from the strip (Fig. 5).
after which it may be returned to its initial or non-operative position.
More particularly said locating means comprise a series of spaced gauge stops on rod 21 between brackets 25, 26, corresponding in number to the number of samples to be taken for each set and of such length the normally extend below the path traveled by the strip as it moves toward the coiler. Three of these stops 30, 3|, 32 are usually employed but of course if it be desired to take more or fewer samples during a single progressive forward movement of the apparatus across the strip, a correspondingly larger or smaller number are provided. Preferably the stops are adjustably secured on the rod in any convenient way, as by set screws 34, so they will extend generally normal to the plane of handle 28 which normally lies substantially parallel to the path of the strip, the stop 30 being positioned adjacent and in front of bracket 25 so as to transfer a rearward push on the rod thereto and thence to the frame. It will thus be apparent that when the apparatus is pulled forward by means of the handle from the inoperative position of Fig. 3 its progress will be arrested in the position of Fig. 4 by engagement of the lower end of stop 39 with the rear edge of the strip, thus locating the punch for taking the sample from adjacent that edge. The operator then actuates the control means for the piston in cylinder I!) so as to drive the punch down, punch the sample from the strip and return the punch to raised position.
He then turns handle 28 in a clockwise direction when viewed as in Fig. 1 so as to correspondingly rotate rod 21 and raise the stops substantially to the dotted line position. indicated therein in which they extend above and substantially parallel to the upper face of the strip, and draws the apparatus toward him sufficiently to bring stop 30 above its surface meanwhile turning the handle in counter-clockwise or reverse direction so as to lower stop 3| sufiiciently to engage the rear edge of the strip when it reaches it and thus position the punch for taking the second or cen- To enable a full reverse movement of the handle, the lower part 36 of stop 36, and likewise the lower part 3| of stop 3!, is hinged to the upper part in such manner that when the lower corner of either stop engages the strip as the handle is being turned back to initial position, the hinged part can swing upwardly and ultimately assume substantially the position of Fig. 2, the hinge being preferably designed to permit the hinged part to turn outwardly but not inwardly with respect to the upper part.
The punch is next operated to form the center sample, the handle again turned clockwise to raise the stops and the apparatus pulled still farther forward while the handle is being returned to initial or horizontal position until stop 32 engages the rear edge of the strip and so locates the punch for taking the third sample from near its forward edge (Fig. 6), the lower parts 30' and 3| of stops 30 and 3| both turning upwardly and outwardly as above explained. Obviously it is unnecessary to hinge the lower part of stop 32, constituting the last in the series, since it is never necessary for it to engage the face of the strip, limiting, as it does, the ultimate essential forward movement of the apparatus.
Afterthe third sample has been formed the apparatus is returned to the initial position by pushing on the handle which is preferably turned in a clockwise direction to lift stops 30, 3| entirely ri ldiii h y: th nh a i edzt f ns the sa el s h ever d sired, hile he t ipis a s as en a ee i e t e ov d f m. e eoiler a d, the lea nc d o he uhe i d fo low g art at-- aeh d th eto r formation. o the su c ed-inscoil, and as the manner of its operation will be ead y und rst od; f m. h ts alrea y be n said further reference. thereto would be superfillets.
