IPC: A21C5/08
Filed: 1929-04-30
Abstract: 334,227. Schr÷der, H. April 30, 1929. Dough dividing and working machines; rolling- machines.-The dough is placed on a working table 12, pressed flat by a pressure plate 13, cut up into separate portions by a series of knives 14 and the pieces worked into a round shape in the cells formed by the knives to which a circular movement is imparted, which movement can be varied from zero to a maximum during the working of the machine by operating a hand lever or pedal 32. The upper part 2 of the machine is hinged at 3 to the frame 1 and is turned upwards by a hand lever 4, gears 5, 6 and levers 7, 8 to insert a plate 10 carrying the dough and having recesses 11; this plate is secured to the fixed working table 12 by pins, the head 2 closed and a ring 15 with the pressure plate 13 and knives 14 moved downwards to press and divide the dough. Circular motion is then imparted to the pressure plate 13 and knives 14, the ring 15 having extensions 17 mounted in sockets 16 on a rail 20 in which are freely mounted crank pins 19 adjustable on crank discs 23 continuously rotated by worm gears 40 driven by worms on a transverse shaft. Normally each crank pin 19 is held by springs 42, Fig. 6, at the centre of the disc 23, the pressure plate and knives then being stationary, and by depressing the hand lever 32 fixed to a shaft 31 slides 25 carrying the crank pins 19 are moved to the right by links 33, 34, 35 and rods 27 sliding within the crank discs and connected with the slides 25 by links 26. The throw of the members 13, 14 working the dough depends on the amount by which the hand lever 32 is depressed. On release of the hand lever 32 the slides 25 with the crank pins 19 return to the central position and the parts come to rest with the knives 14 clear of the dough pieces, avoiding injury of the skin. The crank discs 23 are covered by caps 22 to exclude flour dust, dough, &c., the caps having slots 22<1> in which the slides 25 move. Fig. 8 shows a. modification in which operation of the lever 32 to start the gyratory motion of the pressure plate 13 and knives 14 also raises the pressure plate slightly to allow for expansion of the dough. The lever 33, Fig. 3, is connected by a link 50. Fig. 8, with a lever 51 on a shaft 52 having at the side of the machine an arm 53 connected by an adjustable rod 55, 56 with a lever 58 pivoted at 59 and acting by a forked end 58<1> on projections 60 fixed to a ring 49 carrying the pressure plate 13. To adjust the height of the pressure plate for various sizes of loaves the rod 55, 56 is adjusted by studs passing through holes. The rods 27 may have inclined surfaces acting on corresponding surfaces of the slides 25 to vary the crank length. The initial position of the slides is adjusted by a bolt 44, Fig. 6. The circular dough-working movement may be made by the working table 12 or by both the upper and under parts.

Patent GB-437661-A (GB)
Title: Improvements in articles comprising plastic compositions containing vinyl resins andprocess of making the same
IPC: B29C55/30
Filed: 1934-05-04
Abstract: Hollow articles, such as flash-lamp bodies, are produced by making a hollow preform of a vinyl resin composition, preferably by extrusion, placing said preform within a matrix which may if desired form part of the final article, expanding the heated preform by fluid pressure against the matrix, and maintaining the heat and pressure until the resin is "heat stable," i.e. until all the elastic stresses in the body are released.  The resin compositions are preferably produced by the conjoint polymerization of at least two compounds from the group comprising vinyl halides, such as vinyl chloride, vinyl esters of lower fatty acids, such as vinyl acetate, propionate, and butyrate, and vinyl benzene.  About 70 per cent to 95 per cent by weight of vinyl halide is preferred.  Basic stabilizing materials, such as calcium stearate and hydrated lime or alkaline earth metal soaps in amounts of 1 per cent to 3 per cent, may be added, also filling materials, such as cotton flock, wood flour, silica, mica, talc, asbestos or slate flour up to 50 per cent by weight of the total, and coloured pigments.  When the preform is made by extrusion lubricants, such as carnauba, candelilla or ceresin wax, halogenated diphenyl and halogenated naphthalenes, may be included in proportions up to 10 per cent by weight of the total, about 3 per cent being preferred.  As an example, 20 per cent of vinyl acetate and 80 per cent vinyl chloride were polymerized in the presence of acetone and about 1 per cent dibenzoyl peroxide as a catalyst at 30 DEG  C.  The resulting resin was compounded with 3 per cent carnauba wax and 2 per cent of alkaline calcium stearate and mixed at 125 DEG  C.  It was then extruded under a pressure of 2500 lbs. per sq. in. to form a tube of 1 in. external diameter. This was placed while hot inside a 1 1/4 in. iron pipe and expanded by compressed air at 5 to 10 lbs. per sq. in. The tube was then heated to 110 DEG  C. for 15 minutes to bring it to a "heat stable" condition.  Articles such as toys, vases, electrical parts may be formed by the process.  The finished articles may be dipped in solvents such as ketones, halogenated hydrocarbons, e.g. chlorobenzene and ethylene di-chloride, and esters, e.g. ethyl acetate, to impart a glossy surface thereto.

Title: Improvements in duplex electric welding machines
IPC: B23K11/31
Filed: 1920-05-20
Abstract: 167,873. Ledwinka, J. May 20, 1920. Welding.-A duplex electric welding machine consists of a continuously rotated powerdriven shaft mounted in a frame and having at each end a face-plate which carries an eccentric pin engaging a slotted electrode-carrier so as to reciprocate one electrode of each pair towards and from a co-operating electrode, a separate transformer for each pair of electrodes being mounted in the frame. As shown in Fig. 3. a shaft 14 mounted in the overhanging portion 21 of a frame 11 containing transformers 12, 13, is driven by worm gear from a shaft 18 driven from the main shaft by change-speed gear such as a belt and cone pulleys. A movable electrode 22 at each end of the framing is carried by a slotted slide 46 reciprocated by a bushed pin 49 adjustable in a faceplate 48 on the end of a shaft 37, which may be clutched to a shaft section 29, connected to the shaft 14 by a friction coupling 25 so as to avoid springing or bending of the shaft 14 or injury to the electrode slides due to acting on work of too great thickness and other causes. Each friction coupling consists of a collar 25 on the shaft 14, Fig. 5, connected by spring-pressed bolts 34 to a a disc 32 pressed against a flange 27 on a sleeve 28 keyed to the shaft section 29, fibre discs 33, 31 being interposed between the disc 32 and flange 27 and between the flange 27 and collar 25. Each sleeve 28 is provided with a toothed clutch member 38 engaging a similar member 39 on a sleeve splined to its shaft 37 and operated by a handle and yoke 40. In order that the clutches may be engaged only in one position of the shaft 37 so as to avoid disturbance of the timing of the welding operations, each clutch member 39 is grooved to engage, when in its stationary position, a screw 45 fixed to the framing, but to move out of engagement therewith on sliding the clutch member forward. Rotary switches 51 on the shafts 37 engage pairs of contact members 57, 58 in series in the primary circuits of the respective transformers. The switch is of the type in which two relatively adjustable contact strips are mounted on an insulating disc and engage a third contact fixed on the disc so as to permit adjustment to vary the duration of the welding-current. One terminal of each secondary is connected to its respective electrode 22 and the other to a copper bar 62 secured to and insulated from the framing 11, Fig. 7. On each bar is vertically adjustable an arm 24 carrying the fixed electrode, the part 60 contacting with the bar being of copper. Each arm is fixed in adjusted position by an insulated bolt 65.
