AT TORNEYS INVENTOR.
larly pointed out in Patented July. 28, 1942 SHEET MECHANISM AND METHOD FOR OPERATING THE SAME John Cronshaw, Brooklyn, N. Y., asslgnor to E. W. Bliss Company, Brooklyn, N. Y., a corporation of Delaware Application May 23, 1941, Serial No. 394,873
Claims.
The present invention relates to sheet feeding mechanism as used in a body maker of a can making line andis more particularly concerned with a device for receiving the shock of the incoming body blanks, which are taken into the 1 machine from a feed-in mechanism at a high rate of speed. By my improved device extensions of the body blanks which later on form the tongue to be engaged by a key opener are protected against the impact of the delivery thrust, whereby loss of material, which hitherto oc-,
"curred, due to bending or of this tongue, is avoided.
In a body maker of the type described, sheets are delivered, stacked up in piles in a magazine,
the rate of delivery being about 100 per minute.
' In the forming of blanks as practiced heretofore the blank, when being fed in, was thrust against the frame of the machine in a way that caused the extension or tongue which arrived there foremost, to bear the whole impact. As a consequence thereof many of these tongues were bent or broken, the whole blank becoming damaged thereby.
The present invention overcomes this draw-.
back by providing a special arrangement for the protection of this most exposed part of the blank. In order to prevent the protruding tongue from being thrust against the side wall of the machine, a member of a particular shape is interposed at the part of the body maker where the blank is fed in between the wall and the incoming blank. This member, which extends over the 7 base plate of the body maker for the, greater part of its length. receives the impact of the blank as a whole, whereas the end portion of said member extends upward at an angle with the base plate, leaving a free space or clearance for the tongue of the blank toslip in free of impact.
To the accomplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particuthe claims; the annexed forth in'detail certain mechanism embodying the invention, such disclosed means constituting, howeveabut one of various mechanical forms in which the principle of the invention may be used.
In said annexed drawing:
Fig. 1 is a perspective view of the body maker;
Fig. 2 is a plan view of the parts of the machine forming the invention;
Fig. 3 shows the same parts inside elevation; and
Fig. 4 is a section on line 4-4, Fig. 2.
Referring to Fig. 1, 5 is the frame of a sheet feeding mechanism through which a pile of blanks I are fed in a known manner over a transfer mechanism I to the bed plate I of the station from which the blanks are started .on their way through the body maker and which will be hereafter called the starting station. The blanks,
one of which is shown at 9, are moved on a rack ll successively past the notching, hook-forming and bumping stations respectively, all of which do not form any part of this invention and are, therefore, not included in the following description.
Bed plate 8 is carried by a frame I I with standards i2, it. On bed 8 a frame I5 is located, consisting of three plates I6, l4" and 30, best seen in Fig. 4. Plate It carries two bars H which serve for receiving the blanks at the starting station. Fingers ll, ll on these bars, capable of reciprocating movement, pick up the blanks and feed them through the machine to the several working stations as set forth above.
The plate ll extending in a plane perpendicular to the other two plates, forms the side wall of the starting station. The third plate 30, having a slot ll, is secured to the machine frame by a bolt 32. The connection is slidable in a horizontal plane and makes it possible to adjust the size of the starting station in accordance with the blanks under treatment in a manner known of the sides, 4, extending for its entire length over plate It. The second side, b, forms an angle with the plane of plate It, thus leaving a clear space for the tongue 2! to slide in when'the blank is fed into the starting station. At the other side of lever, ll a'sprlng 22 is mounted drawing and the following description setting between pins 23 and 24 secured to the lever and the side wall respectively, which holds down the lever in its normal position above plate I! and returns it to the same if it is removed by action of the tongue as set forth below. A stop 25 is been started the blanks are fed from the pile i one at a time over transfer mechanism I to the starting station and are received on bars I]. The
main body of the blank 9 is thrust against the lever l9, which is in the position shown in Fig. 3 of the drawing, whereas the tongue 29 slides into the clearance provided by the receding shape of lever l9, not meeting any resistance at all. Immediately after the blank has come in, fingers l8 push it forward in the direction shown by the arrow in Fig. 3. As the blank moves'forward tongue 29 bears against the lever lifting it from its shown position and sliding through underneath side a of the lever, the spring 22 being compressed while it moves on, until the blank has passed fingers l8a. As soon as the tongue ceases to travel along the lever, spring 22 is free to press the lever down again, thus returning the same into the former position on stop 25. Meanwhile the next blank is in position for being fed by the action of fingers l8, while at the same time fingers l8a push the first blank through the body maker proper.
While I have shown the shock receiving member in the form of a lever of substantially triangular shape it will be understood that I do not want to be limited to that particular embodiment of my invention. Any structure equivalent to the lever shown in the drawing, viz., any member receiving the'impact of the blank as a whole while leaving a clearance for the tongue, is within the spirit of the invention and'the scope of the appended claims.
Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.
I therefore particularly point out and distinctly claim as my invention:
1. In a can-body maker in combination, a feedin means for body blanks, means for delivering the body blanks to the starting station, means for feeding the body blanks through the body maker proper, a shock receiving device in said starting station, said shock receiving device comprising a member having an elongated portion for receiving the main portion of the body blanks,
and an angle portion to provide a clearance for a protruding tongue on said body blanks.
