Description
tlnitrll gaines @anni @Mira ROBERT BRIGGS. OF PHILADELPHIA, PENNSYLVANIA.
Letters Patent No. 91,512, dated .Tune 22, 1869.
Be it known that I, ROBERT-BRIGGSZ, of Philadel phia,
,county of Philadelphia, and State ofPennsylvania, have inventedcertain new and useful Improvements in Machines for Shearing Sheets of Metal i-nto Strips 5 and I do hereby declare the following to be afull and exact description thereof, reference being had to the accompanying drawings, making a part of this specification,
in whichi Figure l is a longitudinal section, Figure 2 is a side elevation, and Figure 3 is a top view of a rotary shears, showing the improvements therein.
The saine letters indicate similar parts upon the several views and sections.
A A, the bed-plate.
B B, the stands.
(l C, the shafts.
D D, the conuecting-pinions.
E E, the cutters.
'E F, followers or loose collars.
G G are sleeves, with internal screws.
H H aresleevcs, with external threads.
I I areset-screws, screwed into the adjustable collars F F. v
The adjustable collars F F are fixed by means of other set-screws, the ends of which enter into the shafts C C at c c".
J J, the front crow-bar.
K K, the back guard-plate.
L L are guards.
M M are guard-rolls.
To enable others skilled in the art to make and use my invention, I will now proceed to describe the same.
Upon two shafts, parallel to each other, of sulicient strength, as shown by C C, I place the sleeves HH, which sleeves are slid on the shafts, over the spline c".
The sleeves G G are screwed upon the sleeves H H, and at one end of each sleeve G G is placed the follower-collar F F, so that the cutter-rings E E will be held and spaced by the sleeves H and the followercollars F. I
The right distances having been obtained by the f screws upon G and H, th'e whole system is clamped together, by the screws I I. inipinging upon the fol- Vlower Fat one end, with the permanent collar c' on the shaft C.
This arrangement constitutes the adjustment of the cutters originally, and admits of ready readjustment, to compensate for wear.
Upon the guard-plate K K, the guards L L are placed, so that the end of the sheared strip which has been depressed by the shearing-action of the cutter,- shall pass along the surface of the guard-plate, under the lips L" L", and the ends of the two contiguous sheets or strips which have been elevated by the shearing-action of the cutters, shall pass along the surfaces L L, and be carried above the rollers M M.
The middle strip, thus described as passing 'along Ythe surface of the guard-plate, enters into the grooves of the rollers M M, which rollers can be soV adjusted in the slot M M' that a straight-line direction shall be given to the strip after it emerges from the cutters; and it has been found practicable to shear up ordinary sheet-irons with the ordinary irregular edges as they come from the rolls of a sheet-mill, which edges do not aord any facility of guidance into straight parallel strips, notwithstanding inequalities of thickness, or buckles in the plates, and notwithstanding inequalities of diameters, or unequal sharpness, or irregular setting of the circular cutters, at least within the limits of their irregularities in practice.
In place of the roller at M, a groove can be formed in Ya block of metal, of hardened steel, for instance, but I prefer the construction described.
A similar disposition of guard-plates and rollers, or fixed guard, may be affixed to the back side of shears having reciprocating knives or cutters, as in ordinary plate-shears, only with several cutters, to shear two or more parallel edges at once.
What I claim as my invention, and desire to secure by Letters Patent, is-
1. Combining with the plain and spleened shaft and the cutters, the screw-threaded sleeves, for the purpose of adjusting said cutters, substantially' as described.
2. The guard-rollers; or their equivalent, back of the cutters of shears, such as are used for slitting or trimming plates, in combination with elevating-guards, to carry the contiguous strips or shearings above the rollers, forthe purpose of causing the plate to pass straight through the shears, substantially as described.
