Title: Double cutting metal shears
Inventor: RICHARDS ARTHUR FRANCIS
IPC: B23D31/00
Filed: 1961-02-09
Abstract: 903,556. Shearing; consolidating scrap. RICHARDS MANUFACTURING CO. Feb. 9, 1961, No. 4829/61. Class 83 (4). A double-cutting scrap metal shear comprises a vertical frame structure, an anvil fixed to the frame and including a pair of spaced parallel cutting blades defining an elongated opening therebetween, a reciprocating cross-head above the opening, a pair of cutting blades mounted on the cross-head to coact with the blades on said anvil and power means for reciprocating said cross-head to cause scrap material positioned on said anvil to be consolidated and then sheared on two spaced lines of cleavage. The apparatus comprises a frame 13 mounted on a base consisting of two I-beams 15 and includes two reinforced side members 16, joined at the top by a member 24 which is preferably a casting. The lower ends of the side members 16 are joined by two anvils 40 and 40<SP>1</SP>. Each anvil comprises a horizontal bar 45 which has a downwardly inclined flange 46, and also has a recess 48 to seat a reversible shear blade 49 of rectangular cross-section. One anvil is preferably set slightly below the other as shown in Fig. 7. Secured to the inside faces of the members 16 are guides 50 between which reciprocates a blade carrying a cross-head 55 which has strengthening webs 57 and a bar 60 therebetween. Cutting blades 62 fit in seats formed by the webs 57 and the bar 60. In a preferred construction the cutting blades 49 are held in their seats by bolts 70 which have conical heads 74 and are clamped by nuts 73. The bolts pass through tapered holes 72 in the bars 40 and the reversible blades 49 have double conical holes 71 therein. The upper blades 62 are similarly held by bolts 70 which pass through tapered holes 76 in the cross-head members. Material to be cut is contained in a horizontal hopper leading to the shear and is advanced across the anvils so that the end portion thereof projects beyond the passage 41 by a distance substantially equal to the width of the passage. As the cross-head descends the projecting end portion is sheared off and slides down the inclined flange 46 and the portion over the passage is first compacted and then sheared off and discharged on to a guide plate 42. The crosshead 55 is operated from an hydraulic cylinder assembly 80, 81 by a piston-rod 82. The hydraulic system includes an electric motor 87x driving hydraulic pumps, storage tanks 86 and a solenoid control valve 85. The upper shearing blades may be straight and inclined at an angle to the horizontal or may be of inverted V-formation. In a modification the two anvil blades 49 are at the same height and the upper cutting blades are at different horizontal levels, Fig. 5 (not shown).

Filed: 1916-04-04
Abstract: 100,883. Farge, F. C. July 10, 1915, [Convention date]. Addition to 24223/12 and 100,307, [both in Class 135, Valves &c.]. Clock-work actuation. - Relates to clock-work switches for controlling electric lamps. A circuit closing member is connected to one end of a lever the other end of which engages an eccentric or crank pin the rotation whereof is arrested and allowed at the required intervals by a clock . train. The apparatus shown provides for the extinction of a part of the lights between the times of ignition at night and of total extinction in the morning. The head of the lever g, which is rocked bv the clock mechanism, engages between a pair of spring-pressed conducting-disks b; when the lever is moved in one direction, the corresponding disk is moved up to bridge the terminals i of the circuit fa, f<1a>; when it is moved in the other direction, the circuit f<b>, f<1b> is completed. The crank-pin, shown in dotted lines in triangular form and in contact with the tail of the lever g, projects from one face of a disk at the top of the clock case, from the other face of which projects a stop-pin. The disk tends to rotate in the direction indicated by the arrow; it is held in the position shown by the engagement of the stop-pin with the upper end of a central lever. When, by means of a face cam or circular ramp on the centre arbor of the clock, this lever is moved outwards, the stop-pin is liberated and the disk rotates until the pin is arrested bv contact with the end of a lever shown at the right-hand side. After the required interval this lever is moved aside and the disk moves on until the pin is caught by a lever on the left-hand side. This in turn is moved aside and allows the disk to return to the position shown. In the first part of the movement the triangular pin carries with it the tail of the lever g and a circuit is completed by the left-hand disk b. In the second part, the pin moves clear of the lever which is then thrown over in the opposite direction by a spring, completing the circuit by the other disk. In the third part of the movement the pin again engages the lever.
