To all wlwm it may concern:
Be i known that I, DANIELL. MAINEBI,
acitizen of the United States, residin .at
Canton, in the county of Stark and tate This invention relates to machines for t o enin packs of metallic sheets when the s eets 1n the said pack. have been caused to adhere one to the other, in the process of rolling and shearin a. I t
a The rincipal ob ect of the invent on is to provlde means for quickly loosening one of the ends of the sheets and spacing the saidiloosened ends one from the other.
Another object is .to construct a machine that will simultaneously loosen all of the sheets in an entire pack, at one operation.
With these and otherobjectsin view, the invention consists in the novel construction andlarran ementof parts, hereinafter described, il ustrated -in the accompanying "drawings, and particularl pointed out in the appended claims, it ein understood that various changes in the ormpropor .tions, size and minor details of construction may be made within the scope of "the appended claims, withoutdeparting from thes irit or sacrificingany of theadvantages o the invention.
Inthe drawin .Figure 1 is a front elevation of my evice, showing a pack of sheets in position to be opened.
Fig. 2 is aperspective viewof the presser Fig. 3is an enlarged cross sectional view through the presser plate and the lower die or bed plate which cooperates therewith, the ends of :a pack beingshow-n between the said presser and bed plate. a
r Fig. 4 is a detail-view illustrating the stop for the pivoted crossbar.
Thosefamiliar with the process of manufacturing iron or steel sheets, are well aware of the difiiculty which is ex erienced in opening a pack of sheets, after t e said pack 1 has been rolled, and the edges thereof trimmed upon a shearing machine. Various methods have beendevised to open a pack vast amount of human labor required to do this work, but in even the most modernand well eq ipped shee nulls, the p cks of of Ohio, have invented, a new and useful Metal-Sheet-Pack-Opening Device, of which the following is a specification.
sheets are still opened by laboriously flexing one corner of the said pack with a man" operated pair of tongs until the top sheet of the pack has loosened sufficiently topermit a sharp edged instrument to be inserted to further pry thesheet away from the balance of the pack. This method is still em- 'ployed for the reason that no device prior to this time, has been constructed to satisfactorilydo the work. It is obvious that the above described method is not only slow, but that it requires a vast number of men to handle the output of a modern sheet mill. My invention will not only performthe work. of several men, but will accomplish the result in a small fraction of the time necessary to do it by hand powersince one operation of my machine will open an entire pack instantly.
At 1 is indicated a table upon which the pack of sheets will be placed to be opened.
Secured at either side of the said table are substantial uprights 2 and 5t which are rigidly secured at theirupper ends by a cross bar 5. In each of the uprights 2 and 3 is formed a horizontal bearing 6, which bearings are in horizontal alinement and are designed to receive the opposite ends of a crank shaft indicated at 7. One or more cranks shown at 8 are provided upon the crank shaft and'a connecting rod 9will be attached in the ordinary manner to each of said cranks. Hingedlyi fastened to the lower end of each of said connecting rods is a plunger 10 which plunger is mounted to slide vertically through bearings 11 formed in a cross bar 12 which is pivotally secured to the standards 2 and 4. One extremity of the crank shaft 7 will project through one. of the bearings 6 and carrythereon a gear shown at 14 which gear isiarranged to mesh with a compara- .tively'small gear 15 mounted upon a shaft 16 which in turn is mounted to rotate in a Secured in ahorizontal position to the a lower extremities of the plungers is a presser plate or die indicated at 20. The
- die 20 will beof substantially the. width 50f the pack of sheets to be opened. as
shown in F igI 2', the forward corners of the die or presser plate 20, will be flattened as at 21 for a purpose to be hereinafter set forth, and formed upon the lower side of 10 the said presser plate is an elongated projection 22, which is of slightly less width .and length than the said presser plate and is rounded as shown in Fig. 3. o In direct alinement beneath the. presser plate 'is asimilarly shapedbed plate or lower die 24 which is embedded-in the table 'top 1, the top face of the lower die or bed i 7 plate being slightly above the said table top. The bed plate will be of the exact size 20 and shape of the presser plate and will have itsforward corners similarly flattened, and formed in the upperface of the said bed plate is an elongated depression of the exact proportions to receive the projection 22, if the upper die were broughtinto contact withithe said lower diet Referring now to F ig. 4, the cross arm 12, Wl11(}l1 aspreviously described, is pivotally secured between the standards 2 and 4, is provided with a projecting finger 25, which finger is arranged adjacent the standard 2. A pairof stops 26' and '27 carried by the said standardv arelocated oneon: either side of the finger and are spaced very slightly therefrom.-The'plungers l0, sliding through the, cross arm '12, are thus permitted a slight amount of play in descending, allowing the upper die orpresser plate 20, to approach the limit of its downward travel 40with its forward edge very slightly higher 'than its rear edge.
It will be obvious that asv the bottom of the downward stroke is reached,'the connecting rods 9 and plungers 1 10 will be in perfect vertical alinement, thus bringing the plate 20 into horizontal posigion, the said plate describing an arcin so The packpofsheets indicated'at 30 will be placed upon the table 1 with the forward edge of said pack projecting slightly beyond the forward edge of the bed plate 24' as shown inlFig. 3. The-lever 20 will then be operated to shift the belt 18 on tothe tight pulley, thus starting a rotation of the gears '14 and 15 and the crank shaft 7. A down ward movementof the cranks 8 will cause the" plungers 10 to lower the presser plate 20 and bring the projection 22 thereon into contact with the top sheet of the pack. Be-
9 cause of the peculiar shapes of the presser plate 20 andthe' bed plate'24: and their par- 7 ticulari' points of contactupon the "upper V and lower'sid'esj off the pack, together with the slight rearward. movement of the plate 2043s it come sfinto contact with the top of thepack, the ends of the sheets in the said pack will begin to separate, this separation commencing first at the forward corners of the pack and in front of the flattened corners of thesaid presser and bed plates. As the pressure from the descending plate 20 increases, the separation of the sheets will extend from the corners toward the center along the front edge of the pack until each of the sheets is entirely separated from adjacent sheets for its entire length at the front edge.
The press mechanism shown in the draw- -ingsand described above, is simply illustrative of a type of mechanism for lowering the presser plate, but it 1s obvious that any well known type of press may be used, or,
a steam or compressed air cylinder with a piston working therein and having a connecting rod attached to the presser plate, may be employed. It is also obvious that should a compression cylinder be used, but one plunger connecting through the presser plate will be necessary.
Having now described my invention what I claim and desire to secure by Letters Patent is 1. In a device of the character described,
an upper die flattened upon its forward. corners and a lower die flattened upon its forward corners and arranged in vertical alinement with said upper die. 2. In a device of the character described, a movable die of substantially the width of the pack of sheets designed to be opened, the said die being flattened at its forward corners and a stationary die flattened at its forward'corners and arranged. in vertical alinement beneath'said first die.
3. In a device of the character described, a vertically 'movablc die having flattened portions at its forward corners and a stationary die having flattened portions at its .forward corners and arranged in vertical alinement beneath said vertically movable die.
