METAL-SHEARING MACHINE.
Specification of Letters Patent.
Patented May 23, 1911.
Application filed October 19, 1910. Serial No. 587,945.
To all whom 'it may concern:
Be it known that I, KARL lVAoH'rnR, a subject of the King of W iirtemberg, residing at lVeingarten, Kingdom of Wiirtemberg, German Empire, have invented certain new and useful Improvements in Metal-Shearing Machines, of which the following is a specification.
This invention relates to certain new and useful improvements in metal shears.
The invention has for its object the provision of simple and improved means for supporting angle irons and T-irons in p0sition to be operated upon by the shears.
A further object is to provide means for adjusting the support to permit right or left bevel cuts at an angle less than 45.
The invention will be hereinafter fully set forth and particularly pointed out in the claims.
In the accompanying drawings :Figure 1 is a front View of figured iron shears embodying my improvements, the parts being adjusted for a rectangular cutting of figured iron. Fig. 2 is a detail illustrating the parts in position for a left bevel or miter cut. Fig. 8 is a section through Fig. 2 on the line 33. Fig. 4 shows a back-View of the figured iron shears with the angle-iron put in for a left miter cut, the support being in the rear. Fig. 5 is a front view of the shears, the same as Fig. 1, with the angle iron put in for a right miter cut. Fig. 6 is a detail front view illustrating a slightly different form of construction in the same position as Fig. 1. Fig. 7 is an end view of Fig. 6. Fig. 8 shows the support according to Fig. 6, adjusted for a left miter cut. Fig. 9 is an end view of Fig. 8.
Referring to the drawings A designates my improved metal shears as an entirety the same comprising a base B and a rotary cutting member B. Secured to one side of the shears A is an adjustable member a provided with a laterally extended tongue 6 on which is slidably mounted a carrier 0 provided with beveled ends. Said carrier is locked in its adjusted positions by means of a plug-bolt (Z carried thereby and adapted to engage any one of the recesses e f or g in tongue 5. As illustrated in Figs. 1 to 5 .the opening in the carrier 0 for tongue 5 is nearer one end of the said carrier than the other, whereby said carrier serves as an abutment member and is provided with a long projection c and a short projection 0 either of which may be placed in operative position by simply reversing said abutment member.
An opening D is provided in the shears to receive the metal 71. to be cut, said metal being supported by the edges of said carrier or opening and said abutment member 0.
In the position shown in Fig. 1 the abutment member 0 is in its medium-position, and the plug bolt (Z has entered the middle hole 6 of the guide rail 5. The longer end 0 of the tongue is pointing upward. In this position the tongue serves only as a down holder and an abutment or support for the rectangular cutting of angle and T-irons. If now the abutment member a is reversed so that its shorter end points upward, and then adjusted to the position where plug bolt (Z engages the left hole f of the guiderail 6, it cooperates with opening D to support metal h in position to provide a bevel cut at an angle of less than 45 on the left side. The shears can likewise be used after locking the abutment member C at the right hole 9 of the guide-rail b for beveling angleirons on the right side at an angle of less than 45. Each of the projections c c has beveled side and front faces, whereby the abutment is produced.
In the form of construction illustrated in Figs 69 the abutment member is not moved from the guide rail 6, but is here provided with a suitable insert piece Is. Said insert piece 70 is reversible and provided with two parts k, 70 of different lengths either of which can be inserted in the carrier 0*. In the adjustment according to Figs. 6 and 7 the shorter end k of the piece is is fixed in the carrier 0 and the long end k is at the top so that the down-holder is exactly in the position shown in Fig. 1 for holding down angle and T-irons when they are cut rectangularly. If now the tongue 0 is shifted and the piece is reversed (Fig. 8) this adjustment serves exactly the same purpose as Fig. 2, namely as an abutment for cutting angle-irons under an angle of 45.
I claim as my invention 1. The combination with metal cutting shears, of an adjustable member provided with a lateral tongue, a reversible abutment member, and means for adjustably supporting said abutment member on said tongue, said abutment member being provided with abutments of different lengths.
2. The combination with metal cutting shears, of an adjustable member provided with a lateral tongue, a reversible abutment member, and means for adjustably supporting said abutment member on said tongue, said abutment member being provided with abutments of diiierent lengths, said abutments being each provided with beveled side and front faces.
8. The combination with metal cutting shears, of an adjustable member provided with a lateral tongue, a reversible abutment member, and means for adjustably supporting said abutment member on said tongue,
said abutment member being provided with abutments of difierent lengths, and means for locking said abutment member in any ad justed position.
4. The combination with metal cutting shears, of an adjustable member provided with a lateral tongue, a carrier adjustably mounted on said tongue, and a reversible abutment member removably secured in said carrier and having abutments of difierent lengths.
In testimony whereof, I affix my signature in the presence of two witnesses.
