Description
BREAK GAUGE SETTING DEVICE Filed Dec. 10, 1951 INVENTOR. M4 1 14M 1/. W0:
A? ran/yr) Patented July 27, 1954.
UNITED srrss OFFICE BREAK GAUGE SETTING DEVICE William .l. Noe, Marion, iowa, assignor to Collins Radio Company, 'Sedar Rapids, Iowa, a corporation or liowa 1 Claim.
This invention relates in general to means for setting a stop for accurately positioning a workpiece which is to be bent.
It is oftentimes desirable to break a workpiece, as for example, to form an angle which might be 90 degrees. The thickness of the material and more important the width of the punch at its narrow section must be considered to obtain accurate dimensions and it becomes difiicult to lay out on the fiat sheet the point of contact of the breaking die.
It is an object of this invention therefore to provide a break gauge setting device that may be used for setting a backstop as a reference for the workpiece.
Another object of this invention is to provide an adjusting instrument for accurately and quickly setting the position of a stop.
Further objects, features and advantages of this invention will become apparent from the following description claim when read in View of the drawings, in which:
Figure 1 is an isometric view of the break gauge setting device of this invention;
Figure 2 is an end View of the setting device;
Figure 3 is a sectional view taken on line of Figure 1; and,
Figure 4 is a bottom view of the setting device.
Figure 1 illustrates a base plate it which might form a supporting plate or" a breaking die. A stop 5 i is mounted at one edge thereof. The stop H is received in a pair of slots it, one of which is shown. As best seen in the sectional view of Figure 3 a Wedge shaped member i is received in the tapered slot i2 and a threaded shaft in is threadedly received therein.
A knob ll is attached to the upper end of shaft 16 and clamps down on the member ii. There are two clamping assemblies which thus make it possible to adjust the stop 5 5 relative to the plate Iii.
A female breaking die 58 is mounted on the base plate Iii and is formed with a V-shaped opening it into which the male punch (not shown) presses the material to bend it.
The problem presented is to set the stop I i relative to the die it so that when the workpiece is bent, the bend will be formed a desired distance from the outer edge.
This is accomplished by the break gauge setting device which comprises a body portion 2i which is generally rectangular in shape and which receives slidably therein a rule 22. The rule 22 is formed with a longitudinal groove A. hook clamp 22 passes transversely through the blocl; it so that the hook 2% at the end of an internally threaded sleeve ii engages the groove 23 as best shown in Figure 2. A knob 2'1 2 is fixed at the end oi a threaded shaft 42 that mates with sleeve ll and may be rotated to tighten the hook 25 in the groove 23 and thus to lock the rule 22 so that it will not move relative to the block 2 I.
A pair of vertical pins 28 and 29 respectively, extend transversely through the member 2| and have sharp points iii and 32 respectively. Screws it and 3:3 loci: the adjustable pins 28 and 29 to the block 2 I.
Figure l illustrates a plate 37 which is attached to the bottom of the block 2!. A rectangular opening #2 3 has aback edge it in alignment with the points of pins BI and which pass through openings 55 and 36. To set the gauge to the desired dimension the rule 22 is set so that the desired dimension is indicated at the back edge 44 of the plate 37. The knob 2'! is then tightened and the points ti and 32 are seated in the bottom of the V It. The stop H is set so as to engage the end 36 of the rule 22. It is then looked in place and the gauge may be removed. The workpieces may then be placed against the stop I I and the male punch actuated.
Although this invention has been described with respect to a particular embodiment thereof, it is not to be so limited as changes and modifications may be made therein which are within the full, intended scope of the invention as defined by the appended claim.
I claim:
A break gauge setting device comprising, a generally rectangular body portion with a rectangular groove longitudinally cut therein, a pair of vertically adjustable pins extending through said body portion, internal locking means in said body portion to hold said pins at a desired level, a backing plate covering a portion of said groove with a cut-away portion bounded by an edge in line with a line between said pins, a rule extending through said groove and held between said body portion and backing plate with numerical graduations beginning at one end, fastening means mounted internally in said body portion to fix the rule and body portion in any desired position so that the distance from the end of the rule to the line between the pins may be measured.
