MAGNETIC GRIP.
Specification of Letters Patent.
rammen aug. 22, 1916.
Applicationied March 29, 1916. Serial No. 87,458.
Be it known that I, EDWARD H. WALSH, a citizen ot' the United States, and resident of Chicago. in thecounty ot' Cook and State of Illinois. ha ve, invented certain new and useful Improvements in Magnetic Grips, of which the following: is a specication.
My invention relates to shearing, punching and stamping machines and has particuf Alar reference to a novel gripping or holdlng device for use in connection therewith.
In the employment of shears, it is wellv known that the material to be sheared must be rigidly held or clamped during the shearing operation. If this is not done, the material will move laterallyA and a curved or To obviate this and at the same time to facilitate production it is common to provide three or more workmen charged'with the duty of retaining the plate or bar in its propel' position during the shearing operation. The reason this facilitates production is that the shearing could not be conducted with rapidity if a mechanical clamp was to be adjusted at each operation.
I have conceived the idea of providing a clamp or hold-down device which operates automatically and with rapidity and eliminates the workmen heretofore required for such holding operation. By the use of my. device it vis only essential to provide such workmen as are necessary to properly dispose the article uponV the bed, whereupon the shear or press is actuated and the article is automatically gripped during the shearinf: operation. The result is secured by providing' a plurality of magnets or magnetic gripping devices located below the surface ofthe bed and connected to a source of electric energy,the means of connection being 'in the form'of an automatic switch associatedwith' the main shaft of the shear and which switch.'l is actuated .or completes a cycle of :its movement during each revolution of the power shaft.
The invention will be more readily .understood by reference to the accompanying drawings wherein, f
'Figure 1 is yan-end elevation of a power 'shear 'equipped with my invention; Fig. 2
l vis a front elevation of the shear; Fig. 3 isa plan view of the bed; Fig. 4 is a sectional view through the bed considerably enlarged over that of Fig. 8, and, Fig. 5 is a Wiring diag'rani.
In the drawings I have illustrated the invention as applied to a shear ofthe vertically reciprot-atingr type. include Aframe members 10, a bed l1, to which the lower vshear knife. 12, is rigidly secured. Mounted within the frame is the main power shaft 153. on which the eccentrirs 14. 14. are securec. The reciprocation of the upper shear blade 15, iS brought about by the eeeentries in a manner Well understood.
This device may' Mounted in the bed' l1, are the magnets,
the method of mounting being shown in` Fig. 4. Thesel magnets comprise a core 16, serew-tlu'eaded into the base, the core being surrounded by the windings 17, the surface of the core being made flush and the windinns retained in place by means of the .plates 1S. I have shown a relatively large number ot thesel magnets in the bed', fourteen thereof being' as these cannot be properly carried allin series, I have divided Athem .into two unitsv and connected these units in multiple as best shown in Fig. In that igure'the supply and return wires are indicated at 19, 20, respectively. i at Q1. 22. while the terminals adapted to be connected by the switches are indicated at Q3. Q4. y
The switches which I best shown in Fig'. l` nets are divided into two sections I provide a switch upon each end of the machine,vthe
prefer to employ. are
The ma ,Qnets are ,indicated indicated in Figs. 8 and 5. Inasmuch and where thev magmovable element of the switch being inthe form ot a segment 25, secured to the 'end of .the main shaft by means of the screws or bolts Q6. The terminals 23, 24, are disposed. in thev path 'ofl the disk and as the segment makes one complete revolution atfeach actuation of the shear blade it will be seen that the magnetic devices are operated or are .f
energized during substantially one half of each cycle of operation oftheshear. The portion of the stroke of the shear during which the magnets are energized is of course the active portion orthat which the shearing operation takes place.
f The operation of the device 4is as follows;
Assuming. that theshear is ill-the .position of Figs. 1 and 2, a plate lor bar'trobe sheared 'is located on the bed l1, in proper positonbeportiOn during neath the shear blade 1.5. The mechanismvis then actuated whichA .starts the'- shear into operation. As the shaft 13,-begins torevolve the segment rotates therewith and the terminals'QS, 24, are closed thus energizing the magnets. afThisserves to securely grip or hold the article, the holding action continuing until the shear has retracted and is substantially out of contact with the article.
It will be seen that the device as suggested is entirely automatic in its action, requires no attention or manual operation and may be installed at a very slight expense. 0l)- viously modifications may be made in the construction as shown and such modifica- ,"t1ons as are Within the scope of my claims I consider within .the spint of my invention.
l. In a device of the class described, the combination of a bed and a movable element, a plurality of series of magnetic devices in said bed, a source of electric energy and a pair of switches connected to the main shaft of said reciprocatory element for actuating said magnetic devices during a portion only of the stroke of said shaft, substantially'as described.
2. In a device of the class described, the
combination of a bed and a vertically reciption of said shaft,substantia1ly as described.
3. In a device'of the class described, the combination of a bed, a plurality of magnets mounted in said bed, a reciprocatory element mounted above said bed, an eccentric shaft for actuating said reciprocatory elemeut and a segmental switch member carried by said shaft and so arranged that said magnets are energized durln a portion only of the rotation of said sha t, Substantially as described. v
