Abstract: 128,504. Drewes, J. Dec. 12, 1918. Punching; metal-sheet feeds.-In a machine especially applicable for punching rivet holes in steel plates for ships of the kind in which the work is carried by one frame which is longitudinally movable in a second frame which is movable in a transverse direction, the frames are advanced intermittingly in the desired direction by ratchet mechanism controlled by the punching mechanism, and adapted to be put into gear with the forwarding mechanism of whichever frame it is desired to move. Spacing mechanism for the holes is also provided. As shown in Fig. 1, the work h is carried by a frame i fitted with wheels k moving over # beams l carried by a frame m formed with wheels n which can move over a track o at right-angles to the track l. The punch is carried by a slide b driven by a connecting-rod c, shaft d, clutch e and worm gear f from a shaft g. A crank-pin q on the shaft d drives a ratchet wheel on a shaft p by means of a pawl s and connecting-rod r, and this shaft p can be coupled to pinions t which drive racks u on.the frame i, or a shaft x driven by worm gearing v, w from the shaft p may be coupled to pinions y which drive racks on the frame m according to the particular direction it is desired to move the work. Near the punch 1 are two pairs of spacing pins 2, 3, each pair being at right-angles to the other and spaced from the punch the distance required between successive holes. These punches are depressed by springs 4, 5, which are adjustable by depressing sleeves 7, 8 with heads on which engage the tops of the springs, the sleeves being depressed by pinions on shafts 11, 12 which engage racks on the sleeves. When a pin is to be put out of action its sleeve is depressed sufficiently far to put a connecting-pin through holes 13, 15, or 14, 16, on the sleeve and pin extension, and the whole is then raised by the rack and pinion and held in the raised position by a pawl.

Abstract: 516,092. Electrophoresis. SEMPERIT OSTERREICHISCH - AMERIKANISCHE GUMMIWERKE AKT.-GES. July 16, 1938, No. 21143. Convention date July 27, 1937. [Class 41] A colloidal dispersion is continuously admitted by a tube G to the centre compartment of a cell separated by diaphragms M<1>, M<2> from the electrode compartments N', N<2>. A concentrated dispersion is formed at one diaphragm and is continuously removed, the aqueous phase being removed separately from the neighbourhood of the other diaphragm. In the case of a gold sol, the concentrated dispersion is formed at the diaphragm M<1> in front of the positive electrode and sinks, passing by an aperture into a container B. The aqueous phase rises into a container E provided with an outlet F. When the container B is full, a stop-cock C<1> is closed and the concentrated dispersion removed.by opening a stopcock C<2>. In the case of aqueous dispersions of polymerized vinylchorethylene the concentrated dispersed phase also sinks. The concentrated disperse phase formed when treating rubber dispersions rises into the container E; the supply tube G should in this case be extended into the lower part of the cell. Additional diaphragms may be provided. A number of cells may be provided with common collecting vessels at the top and bottom. The invention is particularly applicable to the treatment of dispersions of highly dilute disperse phase and high electrolyte concentration.

Filed: 1927-08-15
Abstract: 298,729. Stedman, R. F., Barrett, G., and Simpson, G. M. Aug. 15, 1927. Affixing stamps.-The stamps are intermittently fed, damped and severed as they travel from a roll to, and under, a vertically reciprocating head; the stamps may also be cancelled. As shown, the machine comprises an upright 12, Fig. 2, on which is mounted on opposite sides a pair of bosses 17, 18, Fig. 4, of different diameters and a vertical portion 22. The portion 22 is away from the front edge of the machine and is provided with a slot 23 through which the stamps are fed. One edge of the slot serves as one of the edges of a guillotine which cuts the stamps from a roll 24 mounted on the upright 12. A feed drum 40 normally locked to its spindle so as to be driven thereby through the medium of a lever 43 and spring catch, is provided with a number of rings with spaced teeth for engaging the perforations in the stamps, which are fed through a tubular guide 57 to the fixing and cancelling head 59, being pressed against the feed drum by a spring pressed roller 52. The roller 52 and tubular guide are suitably recessed for the teeth of the feed drum. A tank 62 is provided with an absorbent pad for damping the stamps, which are cut by a knife 68 attached to or is integral with the cancelling head. This head at one side slides along the upright 22 and is thereby prevented from rotating, and may carry dating wheels of the usual hand rotated type in a recess therein. The head also acts as a pressure pad for securing the stamp in position and, when required to cancel the stamp, may have an indiarubber or other stamp fixed to the head on one side of the rotating wheels of the dating press. An inking- roller 69 carried by a spring pressed pivoted arm 70 is shown in its position for inking the cancelling and date mechanism, and is moved away therefrom by the downward movement of the head. The main driving gear comprises a handle 86 mounted on a spindle 36 carrying ratchet gearing working between stops, which are adjustable to determine the limits of throw of the lever which carries a spring pressed pawl 74 engaging a ratchet wheel 75 integral with or fixed to a spur wheel 76 which drives a spur wheel 78 on the feed drum 40. Movement of the cancelling head is obtained from the spindle 36 by means of a driving plate 79 slotted at 80 and provided with a pin which is in part reduced to engage a vertical slot in the upright 12. The slot in the driving plate is longer than that in the upright so as to allow of the feeding movement of the stamp to be ahead of that of the cancelling head.

Filed: 1922-08-09
Abstract: 186,042. Seguin, E. Sept. 12, 1921, [Convention date]. Addition to 179,195. Fluid-pressure.-The valve described in the parent Specification is connected at a<1> to the brake exhaust and at a<2> to the brake reservoir, and operates to prevent release of the brakes when the pressure in the reservoir is low. The brake pipe exhausts past a valve d which is held on its seat by a spring d<1> and air pressure until moved by the rod c<1> of the spring-pressed piston c, which is subjected on its under side to reservoir pressure. The piston c is fitted with & cupleather c<2> and a cup c'. The valve d has a perforated tubular stem d<2> containing a spring d<7> contacting with the head of a bolt d'. In operation, as the reservoir pressure increases, the piston-rod c<1> moves the bolt d<4> upwards, compressing the spring d' until finally the valve d is opened, thus permitting the brake to be exhausted when desired.
