UNITED STATES PATENT OFFFICE.
HENRY C. DOLE, OF ADRIAN, MICHIGAN.
SHEARS FOR SHEET METAL.
Specication of Letters Patent No. 15,069, dated June 10, 1856.
To all whom it may concern Be it known that I, HENRY C. DOLE, of the city of Adrian, in the county of Lenawee, in the State of Michigan, have invent-ed a new and useful Machine for Cutting Sheet Iron, Tin, and other Like Materials; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l is a general view of the machine; Fig. 2 represents the top blade of the shears; Fig. 3 represents the eccentric; Fig. 4 represents the bottom part of the shears; Fig. 5 represents the blade, or knife; Fig. 6 represents the rod which attaches the two motions made by the eccentric; Fig. 7 represents a top view of the shears and of the table on which and by which iron is cut into any size desired without the inconvenience of marking.
The following is the explanation of the construction and operation of the machine.
Fig. l shows an elevation of the machine with the shears partly closed, when it will be seen by raising the handle or lever e to a perpendicular position that the blade Z will be raised clear of the lower blade C by reason of the upper part of b being made to slide in the groove f, as the wheel works on its aXis at a. It will also be seen that when the handle is brought down to a horizontal position that the shears will be quite closed by pressing the lower edge of the eccentric wheel upon the top of the blade at b. At the other end of the shears will be seen another eccentric wheel seen at N, which works on its aXis y in the same manner, with this difference: the pitman y', lo, being attached farther from the aXis in N than it is in its moving power H it will therefore not move N as far as H is moved, and consequently the shears will not raise and fall at the back end as much as they will at the front end. The holes seen at v o o' are to adjust the shears .at this end. The shears move as seen at z', at which point a slot is cut, as seen at Z, Fig. 2. This slot is covered with a Washer, seen at R, Fig. 1. The slot allows the joint z' to move up or down to suit the movements of the blade made by the eccentric wheel. It will now be seen that by this movement a shear is maintained the entire length of the blade, whereas without this movement the shear angle would be lost at the front end where the shears were near closing, as the two edges would become nearly parallel. In Fig. l Kscrew-heads are seen at 3, 3, 3, 3, 3, &c., which fasten the steel blades to the cast iron beds, and 1cm/,mm &c., are screws which serve to regulate and adjust the edges of the blade by bringing them to a cutting position t-he entire length of the shears.
Fig. 6 shows a plan of the pitman seen in Fig. l at j, le.
Fig. 3 shows an elevation of the eccentric wheel and lever seen at H, Fig. l. y
Fig. i shows an elevation for the bed for the lower blade, attached to which are guide arms or posts of an inch apart, between which the eccentric wheel is placed, its aXis being at a, and the upper blade is made to slide between these posts, as seen in Fig. l and Fig. 7
Fig. 7 shows a plan of Fig. l. e shows the lever; a, a, the arms or posts. K, K, Fig. 7, are cast iron tables, one placed each side of the shears, on which to place the sheets of iron while cutting. Q is a movable slide set to any given length by means of the thumb screws seen at al and inserted into a block that slides in the channels seen at t, t. On the other side of the shears is another slide or gage, seen at M, adjusted the same as Q.. 0, 0, o are short slides adjusted with thumb screws the same as M and Q, and slide in the channels m, m, m.. These small gages are for the purpose of squaring sheets of iron on the table of any width.
The Figs. 1, 2, 3, 4, 5 and so o-n are inches figured on the tables for adjusting the gages for cutting sheet-iron any desired width or length.
C, Fig. 7 shows the thickness of the blades as set in the shears.
Fig. 5 shows an elevation of a steel blade and X shows a section of the same.
I claim as my invention- The employment of pitman J, K, levers and eccentric wheels N, H, constructed as described for operating the blades, C, D, in connection with the adjustable gage Q, in the manner and for the purpose set forth, and I disclaim all other improvements in the premises.
HENRY o. DOLE.
