MACHINE FOR DOUBLING AND SHEARING PLATES.
SPECIFICATION forming part of Letters Patent No. 611,134, dated September 20, 1898. Application filed November 17,1897. Serial No. 658,840. (No model.)
To all whom it may concern:
Be it known that we, THOMAS H. LEWIS, JAMES DORAN, BENJAMIN LEWIS, and EVAN J. LEWIS, citizens of the United States of America, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Machines for Doubling and Shearing Plates, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to certain new and usefulimprovementsin machines fordoubling and shearing tin or sheet-metal plates, and has for its object to provide novel and efiective means whereby the sheet of metal will be doubled, the ends thereof being brought together and sheared or cut automatically by the action of tables for doubling the sheet so that the said ends Will be perfectly even.
The invention consists of two normally-inclined tables or platforms that are pivotally supported in the frames and which are operated by hydraulic pressure or other suitable mechanism which brings the tables to avertical position, thus doubling between the same the sheet of tin-plate or metal which has previously been placed thereon, together with an automatic means for operating the knife with the closing of the tables or platforms, whereby the ends of the sheet are sheared evenly, all of which will be hereinafter more fully described, and particularly pointed out in the claims.
In describing the invention in detail reference is had to the accompanying drawings,
- forming a part of this specification, and
wherein like letters of reference indicate similar parts throughout the several views, in which- Figure Us a perspective view of our inn-- by the frame. Fig. 8 is a similar view of one of the guide-plates attached to the table. Fig. 9 is a perspective view of the shearingknife and its'operating-levers. Fig. 10 is a perspective view of the depressing-bar carried by one of the tables. Fig. 11 is a perspective view of the head-block carried by the opposite table. Fig. 12 is a perspective view of the guide-plates and the scrap-carrier. Fig. 13 is a perspective view of a portion of one of the tables or platforms.
Referring now to the drawings by referenceletters, a designates the frame, which consists of the top and lower side rails, the end rails, the end supporting-legs a, and the central supporting-legs a J ournaled in the top rails of this frame, at each side of the supporting-legs (1 are shafts or rods b, which form a support for the inclined tables or platforms 0 d, which are held normally at an incline of about forty-five degrees. These tables 0 and d are each formed on the rear face, near the base, with a hollowed-out or recessed portion 6 and carry in the lower end, at each side, pivotal pins f, which engage in slots g, provided therefor on the guide-plates h. Attached to the inner face of the frame, over the central supporting-legs M, are the guides In, which are formed with a central longitudinal slot is and at each side of the said slot with curved slots 16 which form guideways for the pins f of the tables, which project through the slots g and into the said slots These guidesk are secured to the frame by bolts 70, passing through openings W, as shown in Figs. 6 and 7. The slot 70 in the guides is provided for the purpose of receiving the flange h, provided on the I guide-plate h, which serves to guide the tables as the said tables are moved from the inclined to the vertical position, or vice versa. These guide-plates h are connected together across the frame by means of a bar 71 centrally attached to which is the piston h carscrap carrier or receiver g, which is inclined at an angle, so as to readily carry off the scrap from the tables onto the receiver 9 secured to one of the end rails and projecting inward to the center of the machine. This receiver is also inclined so as to permit the scrap from accumulating thereon, and is preferably hinged to the end rail A so that, as the tables are brought to a vertical position, the carrier 9 may be depressed by the action of the tables, and as they are again inclined the said receiver will elevate itself to an inclined position. The table 0 is provided with a transverse slot at its upper end, in which operates a bar 0, to the ends of which are secured pins engaging said pieces C and retracting-springs 0 The other ends'of said springs are connected to similar pins secured in the edge of the table. Operating in the same recess in this table and beneath the depressing-bar c is a shearing-knife c, to the rear edge of which are fulcrumed curved levers 0 connected together by a cross-bar c These levers are pivotally supported in yokes 0 attached to the rear of the table or platform 0, and the shearing-knife is held normally out of engagement by means of a coilspring 0 which is attached to the cross-bar c and to a metal band 0 that is attached near the upper end of the table and passes over the shaft 1) and being attached at the lower edge of the table, thus serving as a guide to prevent the tables from falling toward each other while they are being depressed. The table cl is likewise provided in its upper end with a recess or cut-away portion in which is provided a head-block 61', having projecting ends (2 in which are secured pins 61 for attaching thereto the coilsprings (1 the other ends of which are attached to the table din the same manner as the coil-springs d are attached to the table 0, and thus serving to hold the head-block normally in the position shown in Figs. 1 and 2. This head-block is further provided on its underneath side with a cut-away portion d to receive the knife 0 as will be hereinafter more fully explained. This table d is also provided with a metal band d similarly attached to the table 01 as heretofore described for the band 0 that is attached to the table 0. The table 0 carries near one edge a' pin 0 and is provided directly above said pin with an aperture 0, that is designed to receive a pin d secured in the same relative position on the table cl, the said pin 0 being adapted to enter a recess or aperture 61 provided therefor in the table 01 directly beneath the pin (Z These pins 0 and (Z serve as side stops for adjusting the plate in position, and when the tables are closed upon the plate the pins will offer no obstruction to the same by reason of their entering the apertures provided therefor in the opposite tables.
The operation is as follows: The sheet of metal, tin-plate, or other material is placed upon the tables, with the edge thereof engaging the stop-pins 0 and CW, the tables being in the position shown in Fig. 1 of the drawings. The pressure is then applied (be it hydraulic or otherwise) to the shaft or stem 7L3, so as to pull downwardly on the bar 71/2 and thus draw the tables or platforms to a vertical position, which is accomplished by means of the pins f, projecting into the curved slots As the tables are thus drawn into a more inclined position they ride upon the shafts or rods 19, operating over the curved recesses 6, provided in the backs of the tables, until the depressing-bar 0 comes into engagement with the head-block d as the tables are farther drawn downward, and being now in a perfectly vertical position the shafts I) pass out of the curved recessed portions 6 and that shaft which forms a portion of the support for the table a engages the lever-arms c of the knife, thus forcing the lower ends of the same outwardly and thrusting the shear-knife 0' into engagement with the plate, so as to cut the ends evenly against the knife and recessed portion (1 of the head-block (1. Through this operation the sheet of metal or other material that has been placed upon the tables is doubled upon itself between the two tables, and when the reverse motion is given to the operating mechanism the tables are forced upwardly, and as the shafts I) again enter the inclined recesses e provided on the backs of the tables they are again permitted to fall into the inclined position shown in Fig. 1 of the drawings. The withdrawal of the shaft 1), that operates the shear-knife, from engagement with the lever-arms c loosens the springs a to retract the'said shear-knife, and the head-block cl and depressing-bar c are again forced outwardly toward the face of the table by the action of their respective springs 0 cl. This depressing-bar and the head-block are retained in this position for the purpose of engaging the ends of the plates as the tables are being forced together and thus retain the plate on the tables. As the said depressing-bar and the head-block are exactly opposite each other, they are each depressed into the tables or platforms by their respective action against one another and the shearing-knife passes beneath the same and into engagement with the cut-away portion (1 on the head-block, at which point the shearing is performed. In the reverse movement of the machine, in returning to the position shown in Fig. 1, the bent plate is supported by the plate g. The scraps caused by clipping the ends of the plates fall downward into the carrier g and from this onto the receiver g from which point they may readily be removed without interfering with the operation of the machine, and it will also be noted that various changes may be made in the details of construction without departing from the general spirit of our invention.
Having fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-
1. A doubling and shearing machine, comprising two inclined tables, one of which carries a shearing-knife, and means for operating the said tables to bring the same to an inclined position, substantially as shown and described.
2. A doubling and shearing machine comprising two inclined tables which are adapted to be drawn toward each other until they assume a vertical position, and a shearing-knife operated by the tables assuming their vertical position, substantially as shown and described.
3. In combination with two inclined tables, of a shearing-knife operating in one of the tables, and operating mechanism for bringin g the two tables into engagement with each other, substantially as shown and described.
4. In a shearing and doubling machine, the combination of the inclined tables supported by and operating in guides mounted on a suitable frame, a depressing-bar in one table and a head-block in the other table, means for closing the tables together and for drawing the same downward in their guides, and .a shearing-knife operating in one of the tables, to be operated automatically by the downward movement of the tables substantially as shown and described.
5. In a shearing and doubling machine the combination with the inclined tables, of the shearing-knife operating in one of said tables, means for closing the tables together and drawing the same downward, and a suitable frame having a receiving-plate for the scrap cut from the plate by the shearing-knife, substantially as shown and described.
6. A doubling and shearing machine, comprising two receiving-tables, means for operating said tables to bring the same to a vertical position and into close proximity to each other, one of said tables carrying a shearingknife, said knife being automatically operated by the movement of the table, substantially as shown and described.
7. In a doubling and shearing machine, the combination with the supporting frame, guides secured thereto .and provided with stops, tables operated by said guides, the slots controlling the movement of the tables, and a shearing-knife carried by one of said tables, substantially as shown and described.
8. In combination with two inclined tables, of a shearing-knife operating in one of the tables, operating mechanism for bringing the tables into close proximity to each other, and an incline arranged below the tables to receive the offal, substantially as shown and described.
In testimony whereof we affix our signatures in presence of two witnesses.
