Description
NPETERS, PHOTO-LITHOGRAPHER WASH NGTON D C NrTnD STATES PATENT OFFICE.
ISAAC LAMPLUGH, OF SPRINGFIELD, ILLINOIS.
S pcciiioation forming part of Letters Patent No. 42,003, dated March 22, 1864.
T0 aZZ whom, t may concern,.-
Be it known that I, IsAAc LAMPLUGH, of Springeld, county of Sangamon, and State of Illinois, have invented a new and Improved Tool-Holding Frame; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l is a perspective view of my improved frame having tools applied to it for shearing metal. Fig. 2 is a side elevation of the same. Fig. 3 is an end elevation. Fig. 4 is a top view of the bed of the machine, seen by removing the levers and upper shearingtool. Fig. 5 is a vertical transverse section showing the construction of the lower part of the shearingtool and the application of the same to its rail-bed.
Similar letters of reference indicate corresponding parts in the several figures.
The object of this invention is to so construct atool-holding frame that while it is well adapted for receiving and operating punchingtools for making nuts and washers, Snc., it is particularly adapted to the use of tools for shearing metal by furnishing holders and guides for said tools and facilities for manipulating, guiding, and feeding the Stock to the shears.
To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.
In the accompanying drawings, A represents a long wooden beam, which may be constructed with short axles projecting from its sides for receiving small rollers or truckwheels a c, by which the machine can be easily moved from one place to another; or, if desirable, the wheels may `be dispensed with and the beam A secured in an established place. This beam forms the bed for a long rail, B, which is made of metal and rigidly secured along the upper surface of the beamA by metal straps b b, or other suitable means. The beam A forms a solid bed and strengthener for the rail B, and the two (beam and rail) are thus rendered very stiff and strong. At or near one end of this bed A B, and projecting up therefrom, is a strong tie or standard, C, which is bent outward from one side of the rail B, as shown in Figs. l and 3, and slotted or forked at its upper vertical end for receiving the pivoted end of a fish-bellied lever, D, which is in or nearly in avertical plane with the rail B. This lever D extends longitudinally over the rail B and projects out beyond two standard-guides, c c, which are secured on each side of the rail B, as shown in Fig. l, and at the extreme end of this lever D two links, d d, are pivoted, the upper ends of which are pivoted to ahand-lever, E, which is itself pivoted between the upper ends of the guides c c. Thus it will be seen that the free end of the leverD can be depressed with great force by drawing down the hand-lever E. The upper ends of the standards C c c are braced and tied together by the two rods ff, which are secured on each side of said standards and allow the lever Dto work between them. The
upper end of the curved standard C overhangs the rail B insxuch manner that the lever D is brought directly over and in the vertical plane of said rail, so as to allow the free end of this lever D to work between the vertical portions of the guides c c, which arrangement prevents the free end of the lever from moving laterally and consequently changing the position of the tools which may be secured to it.
I have represented in the accompanying drawings two shear-blades, e e. applied to the rail B and lever O, both of which blades are formed alike, so that a description of the construction of one will give a clear understand ing of the other. The lower plate, e, or that which is secured to the rail B, is shown clearly in Fig. 5. It consists of an extended slotted portion, g, and a lip, g', between which and the former is a groove or recessfor receiving the upper edge of the rail B. The upper portion of this device has the cutting-edge h formed on it obliquely to the sides of g g', as shown in Figs. l and 4. The cutting-edge of this shearI is beveled, as shown in Figs. 2, 3, 5, so that this edge will be overhanging and adapted to receive the corresponding beveled edge, h', of the upper shear-plate, e', as shown in Fig. 2, when the lever D is depressed in the act of shearing metal. The upper shear is secured to the lever D directly over the lower shear by means of a bolt or screw, i, which passes through an oblong longitudinal slot, j, made through the projecting side support, g, while the lower shear is secured to the rail B by a screw-bolt, t', which passes through a vertical slot, j', at right angles to the slot j.
The object of forming a groove in each shear is to secure the side supports, 'which prevent Al' any possibility of the edges of these shears deviating laterally from their proper position when the operation of shearing is performed, and the object of making the slots j j', through which the fastening-bolts pass, at right angles to each other is to enable the shears to be adjusted vertically as well as horizontally without entirely withdrawing their respective screws.
By arranging the shears obliquely to their supporting-bars and curving the standards C c c I accomplish two objects-wiz., I can cut off wider and longer strips of metal in avery short machine by passing the stock through the machine in a direction with the cut of the shears, vwhereas if the shear-blades were arranged in a line with their respective bars a strip or sheet of metal longer than the space between the end standards could not be cut lengthwise in the machine; and when thus arranged I am enabled to bevel the two sides of the shears which come together, so that they will clear themselves and prevent any binding in consequence of the lever D moving in the arc of a circle.
By the use of the forked standards C c c, I am also enabled to dispense with double plates, and to thus diminish the weight and expense of the double-plate machine, at the same time securing all the strength required by making the lever D thicker at its middle than at its ends and bracing and stiifening the frame, asV
above described.
If desirable, the slots in the side supports, g g", of the two shear portions e e' may be made in the form of the letter T, so that each one of these portions can be adjusted vertically and horizontally on its respective bar by simply loosening the fastening-bolt.
It will be seen that while my improved frame is peculiarly adapted for the use of shears, it is also well adapted for receiving other tools-such as punches, dies, iid-which can be secured to their respective bars BD in the same manner as described for the shears.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. A tool-holding machine consisting of a a bed, B, curved standards C c, lever l), and longitudinal braces f f, in combination with the diagonal shears c e', all arranged and operating substantially as described.
2. A machine for shearing metal, Src., constructed and operating substantially as described.
