Title: Improvements in or relating to filter apparatus for dry-cleaning units
IPC: D06F43/08
Filed: 1934-03-12
Abstract: <PICT:0436585/III/1> Dry-cleaning apparatus is provided with a vacuum or suction operated filter through which the used solvent is drawn and then returned to the washing chamber.  The filter 10 contains filter elements each consisting of a reticulated corrugated framework supported in openings in a lower suction tube 13, and the whole surrounded by a bag of woven fabric.  The filter is closed with an adjustable lid 16 by which a constant static head of liquid is obtained.  Used solvent such as petroleum, carbon tetrachloride or trichlorethylene flows under gravity from the washing chambers 12 through pipes 11 to the filter from which it is drawn off through a pipe 13 by a pump 14 and returned through a pipe 15 to the washing vessels.  The volume of liquid delivered to the filter is maintained at not less than the suction capacity of the pump 14. A pump may be used to deliver the used solvent to the filter under substantially no pressure, pipes being connected to the pump to byepass excess solvent.  Storage tanks for used and purified solvent may also be provided.  By the use of a suction operated filter, the addition of silica and other filter aids to the used solvent is rendered unnecessary.  Specification 436,586 is referred to.

Title: Self-regulation device for variable discharge reciprocating pumps
IPC: F04B49/12
Filed: 1962-02-28
Abstract: 994,264. Reciprocating pumps. SOC. D'APPLICATIONS DES MACHINES MOTRICES. Feb. 28, 1962 [April 26, 1961], No. 7772/62. Heading F1A. A device for regulating the output of a pump in response to change in pressure in the delivery circuit, comprises a slide 10 coupled to the regulating member of the pump through rod 1 and acted upon by the delivery circuit pressure via an inlet 24 and a piston 23, a series of springs opposing the action of the delivery circuit pressure. Increase in pressure in the delivery circuit above a predetermined value, corresponding to maximum delivery of the pump, produces corresponding downward movement of slide 10 first against a spring 15 and then also against a spring 16 until spill ports in a piston rod 11 are covered preventing its further movement in a sleeve 12. In this position the pump is at zero delivery, corresponding to a predetermined maximum delivery circuit pressure. Should a higher pressure be required in the circuit, the circuit pressure is applied to the underside of sleeve 12 via a valve 26, previously set for connection to a reservoir. The circuit pressure acts to move sleeve 12 upwardly to engage a spring 17 and an abutment 14, thus preventing slide 10 from reaching its zero pump delivery position until a higher pressure has been developed in the circuit. Changeover of valve 26 may be effected manually or automatically. The device regulates a pump such that it may be driven by a motor of constant power output.

Title: Improvements in sheet separating mechanisms
IPC: B65H3/08
Filed: 1929-03-11
Abstract: 324,562. Marks, Sir G. C., (Harris-Seybold-Potter Co.). March 11, 1929. Sheet - separators.- Sheets are separated from piles and fed to the feed rolls 13 of a printing or like machine by means of suction separators 43 movable in suction cylinders 34 against the action of springs 37 which raise the cylinders after the sheet adheres thereto. Separators 43 acting on the front and rear edges of the pile are shown, and in the normal position the tubes 36 of the suckers 43 are kept raised by the springs 37 which act on pistons 35 moving in the cylinders 34. Each cylinder 34 is connected at its lower end to a bye-pass tube 42 connected to an upper chamber 41 fitted with a pipe 45 which intermittently lowers the air pressure in chamber 41. A controlled narrow passage 38 allows air to pass slowly from cylinder 34 to chamber 41, and when the air pressure is reduced in chamber 41 the pressure at the lower end of cylinder 34 falls more rapidly than the pressure at the upper end, and the piston 35 is drawn down to cause the nozzle 43 to contact with the sheet. The piessure at the top of cylinder 34 is gradually reduced, and the spring 37 which is compressed by the lowering of the piston, finally raises the piston and with it the separated sheet. The rear nozzles 43 coact with rising and falling combing rollers 6 operated from a cam 20 on a shaft 19 driven by gearing from a shaft 16, and a pressing device 7 blows air under the separated sheet. The front nozzles 43 are mounted in a cylinder, which is reciprocated bodily by a connecting-rod 32 and a crank. The crank is driven by bevel gearing from the shaft 16.

Abstract: 512,581. Lasting shoes. KAMBORIAN, A. March 15, 1938, No. 8014. Convention date, March 16, 1937. [Class 17 (i)] A bed-lasting machine having wipers of usual form at toe and heel ends is also provided with a gripper at each side only, adjacent to the ball portion, and heated wiper-like setting members extending to the shank on both sides of the fore part. After the toe end wipers have been advanced the grippers tension the upper as the setting members advance to cramp the upper against the edge of the insole. The grippers release the upper as the setting members advance to wipe the margin over the insole and heat it to set cement if this has been previously applied. At the heel end heat and pressure is applied to the quarter to eliminate wrinkles. A last support with a steadying member is used. The setting members 5 are heated and pivoted to a member 5x movable longitudinally of the last, these members being actuated by means similar to those usually employed for actuating wipers. At the ball on each side are grippers 14, 15 each provided with an .elongated stop 14a to guide the margin of the upper away from the insole. The grippers are opened and closed by a pin on a rod 17 engaging slots at the ends of arms 16, and are adjusted towards or away from each other by rotating a collar 61 moving with a flange having cam slots engaging pins on arms 13 supporting the pivots of the grippers. The rod 17 slides in a sleeve 12 carrying guides for the arms 13 and itself sliding in a boss carried by an arm 10 supported by the machine frame. A spring 23 urges the rod 17 downwardly, and a treadle rod 22 raises it. The plates 5 may be somewhat flexible, and are advanced by slides 9, superposed slides 9a moving faster than the slides 9 pressing the plates downwardly. The counter is smoothed by heated members 25, 26 pivoted together. The last support is provided with a steadying member 34 which is actuated by a yielding plunger 40 secured to a slide having an inclined upper surface for raising the toe rest during the lasting operation. A spring 42 allows the work to be positioned. In operation, a pulled-over upper is positioned, the margins of the upper are inserted between the jaws of the grippers, the treadle is actuated to close the jaws. The pulling-over tacks are removed and the treadle further depressed to stretch the upper. The toe end wipers 4 are then operated in the usual way, the surplus material at the toe is trimmed away and the margins of insole and upper are coated with adhesive. The support 5x is then moved rearwardly and the slides 9, 9a inwardly, the wipers 4 being forced upwardly by the underlying plates 5, 5x. As the plates 5 advance the jaws release the upper which is guided into the recess in the member 14a to prevent it adhering, at its edge to the insole. This edge is, afterwards, trimmed. At the heel end the wipers are manipulated before the members 25, 26 are swung hard against the upper. The plates 5 may extend to the shank.

Filed: 1951-04-09
Abstract: 723,768. Dough dividers. BAKER PERKINS, Ltd. March 31, 1952 [April 9, 1951], No. 8153/51. Class 87 (2). Dough is forced into adjustable measuring cavities 2, pushing pistons 7 outwardly until a head 16 of a set screw 14 on each piston engages adjustable spring-loaded plungers 18, the movement of the plungers rotates a pair of bell-crank levers 26 until a lever 24 engages an adjustable block 30, the setting position of which is indicated by a pointer 33. The dough dividing head is then moved and the dough ejected by oscillation of a shaft 20 which returns the pistons. By removal of a pin 28 the levers 26 may be swung upwardly to allow partitions to be inserted in the cavities, to alter the size of the dough pieces formed and to allow a corresponding set of pistons to be inserted. The partitions 4a, Fig. 1, are inserted in grooves 5a either in the cavities or in fixed liners. A locking bar 35 ensures that the partitions are in the correct position and is itself held in position by a catch 39 which controls a switch 40 in such a manner that the machine cannot operate unless the catch is in a locked position. In a modification, the partitions may be formed as interchangeable units, in the form of liners, each unit having a different number of fixed partitions. The units may be introduced axially, vertically or laterally. The partitions may be engaged by external means, e.g. pins, instead of fitting into grooves.
