Title: Plough colter construction
IPC: A01B61/04
Filed: 1972-01-25
Abstract: 1338981 Agricultural implement DEERE & CO 12 Jan 1972 [25 Jan 1971] 3442/72 Heading A1B The front end of a colter arm 12, having a plough colter 10 at its rear end, is connected to a shaft 26 journalled in a mounting bracket 14 and is biased to a working position by either a tension spring 46 (Figs. 1, 2) or a hydraulic device (Fig. 3, not shown) acting between the mounting bracket 14 and a lever arm 38 on the shaft 26 so that if the colter 10 meets an obstruction the biasing means yields to permit the colter to surmount the obstruction. The corresponding faces 32, 30 of the colter arm and shaft are serrated and clamped in a fixed relative position by a bolt 34 which, when loosened, allows the working depth of the colter to be adjusted and which acts as a clutch which may yield to allow slip between the faces 32, 30 if the colter arm suffers a large deflection, so preventing damage to the colter itself. Constructional Details-Spring Biasing Device. The colter arm 12 is pivotally connected by shaft 26 to the mounting bracket 14 which includes a pair of vertical bearing blocks 16 rotatably mounted on the lower end of shank 18, the upper end of which is clamped to the frame of the plough. A lug 24 on the clamp 20 limits the rotational movement of the bracket 14 un the shank 18. The shaft 26 has an enlarged end 28 with a serrated face 30 and carries a lever arm 38 which is forked to receive a pin 42 and the eye of the tension link 46. A laterally projecting spring abutment piece 48 on the bracket 14 extends to the rear of the lever arm 38 and is provided with an aperture 50 through which the tension link 46 extends. A spring retainer 56 bears against the rear end of the spring 54 and is retained on the tension link 46 by nuts 58. When the colter arm is deflected upwards, the spring 54 is compressed until the deflecting force diminishes, at which time the arm 12 is returned to the working position by way of lever 38 and the expansion of the spring. Hydraulic Biasing Device (Fig. 3, not shown). In this case the forked lever arm receives a roller instead of the tension link. A cylinder is mounted on the mounting bracket in front of the lever arm and is connected to a source of fluid pressure, e.g. an accumulator, with its position engaging the roller on the lever arm. When the colter arm is deflected upwards, the roller on the lever arm forces the piston back into the cylinder, the fluid pressure returning the piston and hence the colter arm to its normal working position when the deflecting force diminishes. The rearward movement of the lever arm is limited by the engagement of two lugs on the enlarged head of the shaft and the mounting bracket respectively.

Abstract: 1443077 Feeding sheets J BOBST & FILS SA 29 Jan 1974 [28 Feb 1973] 03959/74 Heading B8R A sheet 7a is separated from the bottom of a pile 7 by a belt 1 which is intermittently advanced over a suction chamber 10 by an oscillating crank 30 operating on a belt pulley 5. The crank shaft 28 is connected to the pulley 5 by a one-way clutch so that the pulley and belt are only advanced during movement of the crank in the direction F2. During reverse movement of the crank the pulley 5 is permitted to "freewheel" whereby advancement of the sheet 7a (and thus the belt 1) by forwarding rollers 33 and 34 is possible. Following complete removal of the sheet 7a from the belt the latter is braked by the suction effect from chamber 10. The rear edge of the pile is supported on a roller 38 and the front edge abuts a stop 9 which provides a sheet feed throat. The crank 30 is driven from wheel 32 by way of link 31. Two similar separating devices of the type described above may be arranged in tandem to operate on a single pole (Fig. 4, not shown).

Title: Novel or improved means for use in counting small articles into predetermined quantities
IPC: G06M1/10
Filed: 1948-02-13
Abstract: 641,200. Counting-apparatus. GUEST, KEEN, & NETTLEFOLDS, Ltd., MONEYPENNY, H. K., TOWNEND, G. H., and BEARDSMORE, F. Feb. 13, 1948, No. 4198. [Class 106 (i)] [Also in Group XL (b)] In apparatus for counting small articles into groups of predetermined quantities, the articles are fed along a trackway A individually interrupting the light to a photo-cell d. Each interruption operates an electronic counter which, on registering the predetermined number of objects energizes an electromagnet i, Fig. 2. This magnet lifts a member j allowing a spring- loaded lever k to swing to its other end position operating a deflector plate f to direct the article from, say, track g to track h. When the lever reaches the other end position where it is again held by member j it closes contacts such as D starting a motor (not shown) which rotates an arm carrying the pin o, to which the spring is anchored, to the other side of the lever pivot l as indicated by the arrow, thereby urging lever k to its previous position. When the arm reaches an extreme end position it breaks the circuit of the motor.
