March 19, 1930, No. 8863. Convention date, March 20, 1929. [Class 107.] Vehicular apparatus for preparing and spreading chemical solutions, such as liquid manure or fungicides on farms, or solutions for removing grass from railway tracks or melting snow in streets comprises a reservoir 3, a vat 1 containing the chemicals, means for moistening the chemicals in the vat with liquid from the reservoir, a pump 4 for conveying the contents of the vat into the reservoir, and a pump 9 operated by the engine of the vehicle for discharging liquid from the reservoir into distributing tubes 14 which are adapted to spread a quantity of liquid proportional to the speed of the vehicle. A valve 2 provided in the reservoir 3 adjacent the vat 1 enables the contents of the latter to be moistened. The suction pipe 5 of the pump 4 leads into the vat and the discharge pipe 6 discharges into the reservoir, and these pipes are either roughened or comparatively long and distorted. The pump 9 communicates with the bottom of the reservoir by means of a suction pipe 7 and discharges to a pipe 12, connected with the tubes 14, and to a return pipe 10 for effecting an agitation of the liquid in the reservoir. The pump 4 is driven from the engine of the vehicle or by an independent motor, and the pump 9 is driven from an axle of the vehicle with the interposition of suitable speed-varying means. The distributing pipe 12 discharges into a cylinder 13 communicating with the series of horizontal longitudinally-disposed outlet tubes 14. Each tube 14 contains a spring- pressed piston 17 as shown in Fig. 2 and has on its underface a number of delivery ports, which may be constructed as so to eject the liquid with an eddying motion. A device comprising a sleeve 21, enclosing an arrangement similar to the perforated tube 14 and piston 17, may be provided in connection with each delivery tube 14 so that when any delivery tube 14 is cut off by a valve 20 liquid is fed instead to the sleeve 21 and thence to the reservoir.

Title: Improvements in or relating to crossing motion pirn winding machines
IPC: B65H54/14
Filed: 1938-03-24
Abstract: 495,618. Winding yarns. MIESCH, C., and ETABLISSEMENTS WECO, SOC. A. R. L. March 24, 1938, Nos. 9038 and 9039. Convention dates, July 7, 1937 and Jan. 4, 1938. [Class 120 (ii)] The guiding of the yarn in a crossing motion pirn winding machine is effected by crossed helical ribs or grooves on a roller or drum which can be moved longitudinally relative to the pirn and the filling of the pirn is completed during a single longitudinal stroke of the roller. The machine shown provides for the winding of two tubes 1, la mounted between the ends 2 of shafts 3, 3a and spring-pressed centres 4. The yarn is guided by helical ribs or grooves 8, 8a on traversing rollers 7, 7a slidably mounted on shafts 10, 10a driven through gearing 11, 12 from the shafts 3, 3a. Forks 13, for moving the rollers longitudinally, are secured to the rods 14 which are connected by a cross-arm 15 carrying thrust bearings for the end of the screw 18 which is engaged in a slide 20. When the pirns and the rollers are rotated for winding the yarn, the shaft 10 drives the shaft 26 through gearing 27, 28 and the tappet 30 on the wheel 29 lifts the arm 31 causing the pawl-and-ratchet mechanism 34, 35 to operate the shaft 32 by a series of steps. This shaft acts through worm gear 42, 43 to rotate the screw 18 to move the traversing rollers 7, 7a longitudinally along the pirns. At the same time the rotation of an eccentric 25 secured to the shaft 26 imparts to the screw 18 and the rollers a rapid reciprocating movement of small amplitude to facilitate the winding of the yarn upon the pirns. The handle 24 can be raised to lift the slide 20 against the force exerted by the spring 25 so as to disengage the slide from the screw 18 to enable the rollers to be set for starting. In a modification, a tapered roller 52, Fig. 5, may be used instead of a cylindrical roller, and the angle at its apex is practically equal to the angle at the end of the pirn; the roller is arranged so that its taper is opposite to that of the end of the pirn. The longitudinal movement may be applied to the pirn instead of the traversing roller.

Title: Method and Apparatus for Perforating or Cutting a Rapidly Moving Strip
Inventor: LEVY MURRAY NATHAN
IPC: B23D31/00
Filed: 1967-03-01
Abstract: 1,150,391. Dividing. E. W. BLISS CO. 1 March, 1967 [17 March, 1966], No. 9617/67. Heading B3W. [Also in Division B4] A method of removing a sample coupon from, or cutting a moving strip comprises providing a punch including a cutting edge on one side and a pressure surface on the other side and having a total height of " x," providing a pair of rolls one on each side of the strip path and rotatable on axes perpendicular to the strip path, the spacing between the rolls being equal to or less than " x," depositing the punch on the moving strip with the cutting edge facing the strip, passing the punch with the strip between the rolls, whereby the cutting edge is forced through the strip and removing the punch from the moving strip after it passes through the rolls. The punch 40 has a circular cutting edge formed by an external bevel so that the coupon is retained inside the punch, which is closed at one end and has a knock-out hole 48 in that end for dislodging the coupon. The punch is secured in a carrier 50 of flexible magnetic material, if ferrous strip is to be cut, or the carrier is electrostatically charged before it is deposited on the strip, so that it adheres and is rapidly accelerated to the strip speed. The punch assembly P is deposited on the strip from a magazine D and is carried by the strip between pressure rolls 62, 70, the peripheral speed of which is equal to the strip speed. The upper roll 62 has a hardened surface and the lower roll 70 has an outer soft-metal covering 72. The spacing between the rolls is slightly less than the height of the punch so that it is forced through the strip. On each side of the roll pass is a guide roller (90, 92), Fig. 3 (not shown), which ensures that the strip does not run on the lower roller when it is passing freely between the rolls. After passing through the rolls the punch assembly is projected from the strip by centrifugal force as the strip passes round a guide roller 10 or on to a reel E. Alternatively, the punch assembly is lifted by an air-blast through the punched hole, caught by a blade positioned just above the strip and directed to a collecting bin. The strip may be divided into lengths by substituting a blade 230 with a cutting edge 232, Fig. 14, for the punch. The magazine D, Fig. 8, comprises a series of trays 122 carried by endless chains on sprockets 114, 116 which are intermittently rotated by an indexing motor 140. The punch assembly P is discharged from a tray on to support fingers 152, 154 by a double-acting solenoid-operated push-rod. The fingers 152, 154 are secured to shafts 156 which are turned by a rotary solenoid 164 to deposit the assembly on the strip.
