concerning

Scissors, especially tin snips

The invention relates to scissors, in particular sheet metal shears.

It is known to arrange adjustable stops for the au-cutting plate on the scissors themselves.

However, this is not always convenient, especially then not, if the width of the piece to be cut off is approximately equal to or greater than the corresponding dimension of the Scissors is.

In this case one usually cuts along one The scratch line previously drawn on the sheet.

The invention is based on the object. one Scissors, on which no stops are arranged or else

at the

/ i'chere existing stops because of the large width of the the plate or the like piece to be cut off cannot be used, the previous marking of the plate avoid.

To solve this problem it is provided according to the invention that a stop on each side edge of the to cutting plate or the like can be fastened and in the cutting position cooperates with its stop surface with the front face of the skirt of the scissors and that each stop has a Hßarm which can be aligned along the side edge of the plate, the length of which is measured from the Stop surface corresponds to the distance between the cut edge of the apron and its front face.

In a preferred embodiment of the invention, each stop has two clamping jaws, between which the edge the plate can be clamped.

In order to be able to align the measuring arm simply on the side edge of the plate, it is in a further embodiment the invention can be pivoted parallel to the clamping plane on the Arranged stop.

The invention and advantageous details of the invention are shown in the following on the basis of relevant drawings explained in more detail using an exemplary embodiment.

Figure 2 is a plan view of a stop "in a Scissors according to the invention,

FIG. 5 shows a section along the line III-III in FIG

The scissors shown in FIG. 1 comprise a lower knife 17 attached to a stationary apron 60 and a upper knife 6 attached to a movable apron plate 16. The scissors frame is denoted by the reference numeral 1B designated. The strength E of the knife 17 carrying, niit The apron 60 firmly connected to the frame 18 is constant over the entire length. So the cutting edge of the machine is opposite the front end face 60a of the skirt 60 offset by the distance E.

On the table 10 and the upper narrow side of the apron 60 a plate t is placed. Dan sheet t is in its position opposite the stationary apron through on its side edges clamped stops 67 can be determined.

One of these stops 67 is shown in detail in FIGS.

Each stop has two clamping jaws 71 and 73, which can be adjusted relative to one another by means of a viewing hood 72, so that the edge of the sheet metal can be clamped in on them.

The stop 67 bears a

The stops according to the invention are used as follows: The outer edge t _{2 of} the sheet metal t to be cut is inserted between the clamping jaws of a stop. After clamping by means of the screw 72, the measuring arm 68 is pivoted _{parallel to the side edge t 2.} In the same way, a second stop is clamped onto the opposite side edge of the sheet metal t, so that the end edges 68a of the measuring arms 68 fall into a common connecting line t 1. When the sheet metal with the stops 67 is pushed against the front face 60a of the stationary skirt 60, the connecting line t forms. the cutting edge, which is thus indicated by the measuring arms 68.

The sheet metal t can also be fastened with the help of hold-downs before it is cut.
