llNrTn STATES CHARLES OBE RLE AND ERNST FALLER,
PATENT OF NORTH TARRYT OWN, NEW YORK,
' ASSIGNORS TO MAX H. O. BROMBAOHER, OF SAME PLACE.
SHEARS.
SPECIFICATION forming part of Letters Patent No. 506,371, dated October 10, 1893.
Application filed August 13, 1892.
To all whom it may concern.-
Beit known that we, CHARLES OBERLE and ERNST FALLER, both of North Tarrytown, Westchester county, and State of New York, have invented a certain new and useful Improvement in Shears, of which the following is a specification.
Our improvement is specially adapted for what are called squaring shears used by tinsmiths.
We will describe a machine embodying our improvement and then point out the novel features in the claims.
In the accompanying drawings, Figure lis a rear view of a machine embodying our improvement, certain parts being broken away. In this View the parts are shown in their normal positions. Fig. 2 is a transverse vertical section taken at the line a: w Fig. l, showing parts in the same position as in Fig. l. Fig.
ferent position. Fig. 4 is a similar section showing parts in a still different position.
Similar letters of reference designate corresponding parts in all the figures. The framework A, of the machine may be It is surmounted by a bed, B, upon which the material to be cut is placed. At the rear of the bed, a stationary knife C is fastened in any suitable manner. In the present instance, it is represented as being sustained vertically by screws c', engaging with tapped holes in lugs a extending rearwardly from the bed B and impinging against the underside of the said knife. In the upper part of the framework of the rear of the bed B are slideways A', in which a cross head O reciprocates vertically. In the cross head O arms o extend downwardly, and at the lower end are pivotally connected with the upper ends of links D, whose lower ends are pivotally connected with cranks E extending from tubular hubs e turning upon studs E', which are bolted to the side pieces of the framework A. These hubs in effect constitute rock shafts. From the tubular sleevesefrom which the cranks E extend other cranks E2 extend at about right angles to the cranks E. They may be formed integral with the cranks E. The cranks E2 have pivotally connected with them the up- Serial 110.443.058. (No model.)
per ends of links, F, whose lower ends are pivotally connected with a treadle lever G, that is fulcrumed by journals or pivots g to the said pieces of the framework A. This treadle lever G extends to the front of the machine.
From the sleeves e of the cranksE E2 arms or rods H extend. As shown, they extend in line with the center line of the cranks E2 but from diametrically opposite' portions of the v6o sleeves e, although somewhat at one side of the crank arms E2 in the direction of the length of the sleeves. To the rods His aflixed a weight I, here shown as made. in the form of a heavy bar having holes which enable it to be slipped upon the rods H and to set screws for clamping it thereon.
The combination of parts which we have described is lsuch as to produce two downward strokes of the upper knife C2 for each 7o depression ofthe treadle. 4We will now describe how this is accomplished.
When the treadle is at rest about half Way throughout its possible range of movement, the crank E will be brought to a vertigle to the vertical, as represented in Fig. 4.
Thus the upper knife C2 will be slightly raised above the lower knife. The arms H will then be elevated considerably. When the pressure on the treadle is relaxed,the weight Iacting through the arms H on the sleeves eupon 9o which the cranks E turn first depress the cranks into a vertical position, as represented in Fig. 3, thereby producing a second out of the knives and afterward will move the cranks E forward, as represented in Fig. 2, thus raising the upper knife above the lower knife and atthe same time elevating the treadle. It will th us be seen that by a single depression of the treadle, two cuts will be produced.
vWhat we claim as our invention, and desire roo to secure by Letters Patent, is
1. The combination in a cutting machine During this move- 8o of a. reciprocating knife, a treadle for causing the reciprocation of the said knife, a rock shaft, a connection between said treadle and the rock shaft, a crank operatedY simultaneously with the rock shaft, a link connecting;f the crank With the reciprocating knife and a weight connected to an arm extending from the crank and which, by the depression of the treadle, will be raised to a point enabling it to reciprocate the knife to make a cut when said weight resumes its normal position, substantially as specified.
2. The combination in zt cutting machine, of a. reciprocatingknife, a rock shaft atreadle for causing the reciprocation of the said knife,
