Filed: 1916-02-22
Abstract: 100,111. United Shoe Machinery Co., (Assignees of Standish, J. F.). Feb. 23, 1915, [Convention date]. Heels, machines for.-A machine for attaching wooden or other heels is provided with means for gripping the tread and rear face of the heel, and with means for adjustably retaining and guiding the gang of tools which operate upon the heel. The invention is described as applied to a heelattaching machine of the type described in United States Specification 1,081,917, the shoe being supported on a jack 4 secured to a stationary frame 3 and being adapted to be clamped by members 20, 28 carried by a reciprocating head 6, which is actuated by a cam 8 and a treadle rod 10. The tread-engaging member 20 is adjustable by a worm and wheel 22, 24 at the lower end of a shank piece 18, while the side-engaging member 28, which is fork-ended and padded, is pivoted for swinging adjustment to a shank piece 26. These two shank pieces are located in an horizontally adjustable table 12, and are geared together by rack teeth and a pinion 40 for equalizing adjustment, the member 20 being normally pressed downwards by a spring 38. For supporting the shoe from the inside, a shank-engaging member 68 is adjustably bolted to the jack 4. The jack 4 has secured to its upper end a pair of spaced plates 50, 52, shaped to the inside of the heel of the smallest shoe and provided with parallel slots through which extend guide-tubes 54 for drivers 48. The lower ends of the drivers, of which there are five arranged pentagonally, carry blocks 49, Fig. 5, for adjustment in slots 45 in a plate 44, which is spaced from a reciprocating plunger 42, while the upper ends of the drivers are bevelled slightly to cause the nails to enter the heel in a converging manner. Eachof the side tubes 54, Figs. 3 and 4, is rigidly set in a gauge block 56 located between the plates 50, 52, these blocks being adapted to be adjusted simultaneously by a slotted frame 58 provided with an adjusting-screw 60. The outer edges of the blocks 56, by contacting with the sides of the shoe, serve to locate the shoe symmetrically with respect to the drivers, and also to determine the distance of the nails from the edge of the work. The rear driver may be adjusted longitudinally in a slot 53, Fig. 3, and is then clamped by a set-nut 62. At their upper ends, the tubes 54 are provided with conical heads to ensure that the nails will be driven with their heads flush with the insole.

Title: Improvements in methods of forcing or raising liquid and of producing power from liquid under pressure and in apparatus therefor
IPC: F04F7/02
Filed: 1922-01-28
Abstract: 196,985. Rusdell, W. J. Jan. 28, 1922. L i q u i d - pressure engines, - A method of producing power from liquid under pressure by means of a piston and column of liquid consists in causing the liquid column alternately to gain velocity at substantially constant acceleration during the working strokes and to lose velocity at substantially constant retardation during the intervening periods. The constant acceleration may be imparted by causing a reciprocating piston, during a considerable part of the strokes in the direction of flow, to exert substantially constant pressure against the liquid column. In the case of forcing the liquid, the piston 6 may be actuated by a specially shaped cam 1 engaging a roller 3 on the piston rod. The piston rod may be controlled by a radius arm. In other forms the cam engages a curved lever connected to the piston; or two pistons are actuated by the cam through two bell-crank levers, or the piston rod is adjustably connected to a lever acted on by two cams; or the piston is connected to a lever actuated by a crank, and the movement of the lever is controlled by a cam engaging its end. The piston may be replaced by a reciprocating or oscillating tube provided with inlet valves, cushioning springs &c., such as are described in Specification 160,120. [Class 102 (i), Pumps &c.], may be used to permit the piston to follow the motion of the liquid column without shock.

Title: Improvements in and connected with cisterns for flushing purposes
IPC: E03D1/30
Filed: 1920-01-30
Abstract: 162,400. Gillespie, A., Dunbar, J., and Gillespie, J. Jan. 30, 1920. Cistern discharge valves.-The discharge valve B, Fig. 2, is connected by a link D with a notched disc E pivoted in a bracket P secured to a side of the cistern. A second pivoted notched disc J works at right angles to the first. Both discs are attached to floats. When the cistern fills with water the float K rotates the disc J until a notch L registers with the edge of the disc E, thus allowing the disc E to rotate under the action of its float and raise the valve B. The float K then descends, locking the other float in raised position, where it remains until the registering of other notches allows it to fall. In a non-automatic form shown in Fig. 5 the upper disc is actuated by the pull chain instead of a float and the stem R of the usual ball-float passes through a slot in the rod Q. When the chain is pulled the upper disc is rotated until two notches register, when the valve B is raised. In another non-automatic form, Fig. 7, the rod Q is replaced by a slotted rod R<5> and the disc R<1> has an angular projection. When the rod is moved so as to bring a slot opposite the projection the valve is raised or the float R' allowed to fall as the case may be. Means for operating the rod R<5> are shown in Fig. 8. A bellcrank lever F<2> is pivoted at 2 and is fitted with a knee-jointed piece F<3>, the rod being depressed by pressure on the knob F<1>. A spring F' restores the original position after actuation.

Title: Improvements in method of and means for magnetically separating solid magnetic particles from a fluid current
IPC: B03C1/032
Filed: 1959-01-28
Abstract: 883,347. Magnetic separators. JONES, G. H. Jan. 1, 1960 [Jan. 28, 1959], No. 3116/59. Class 117. In separating magnetic particles from a fluid current, one or more pulses of short duration is/are imparted in the flow of water used for washing and removing magnetic particles collected on grooved plates situated in a magnetic field. Water for washing the collected magnetic particles is admitted to a chamber 15 of a fluid control unit 5 via a non-return valve 14, and scouring water at a higher pressure, for removing the magnetic particles, passes into the chamber through an inlet 11 and valve 12. An exit from the chamber connects with a housing 7 for grooved collector plates 8 and is controlled by a valve 10. One or more rams 21 extend into the chamber and create a pulsating movement in the water within the chamber; the rams are actuated by spring and cam means, Fig. 3 (not shown). The fluid to be treated passes from a hopper 6 into the housing 7 under the control of a feed valve 9 and the magnetic field is provided by electro-magnets. A funnel 16 is rockable to divert the fluid issuing from the housing 7, and permits non-magnetic particles, washings, and magnetic particles to be collected in separate containers. During operation of the apparatus and whilst a washing period is taking place, the scour valve 12 and the feed valve 9 are closed and the valve 10 to the housing 7 is open so that wash water passes through the non-return valve 14 and through the housing. The rams are released, preferably consecutively, and produce a surge of water past the valve 10. The rams may also be operated when the valve 12 is open, to increase the effectiveness of the scouring. A diaphragm may be used in place of a ram, and the ram or rams may be operated by solenoids, hydraulically or by compressed air. Specification 768,451 is referred to.

A bottle capping or stoppering machine comprises a compound starwheel having plates 16-18, Fig. 1, with peripheral axially aligned notches 19 . . . 21 for engagement with plastics &c. bottles B advanced tangentially past the starwheel by a straight chain conveyer 4, Fig. 2, a top plate 22 of the starwheel having peripheral notches 23 which pick-up bottle caps &c. C one at a time from a cap &c. feed 6. Above each cap &c. receiving notch 23 a vacuum holder 25 is mounted on the top plate 22, and is connected by a pipe (31), Fig. 3 (not shown), to an automatic valve 32, 33 operated by rotation of the starwheel, and thence connected to a source of vacuum. The valve 32, 33 opens as a notch 23 picks-up a cap &c. C from the feed, so that the vacuum holder 25 retains the cap &c. and closes when the cap &c. has been carried round by the starwheel 16-18 and applied to the bottle B. As the cap &c. C is aligned with the neck of a bottle B, Fig. 1, a roller 26 at the top of the vacuum holder 25 engages a cam 27 on a fixed machine support 14 and slides the vacuum holder 25 downwardly through the top plate 23 against spring bias; the cap &c. is thus forced on to the bottle. During this capping &c. process, arcuate guide surfaces on fixed plates 11-13 are engaged by the bottle B and slide it slightly sideways on the conveyer 4, thus maintaining the bottle aligned with the cap &c. receiving notch 23. When the cap &c. C has been pushed home, the cam 27 releases the holder 25, which is no longer connected through the automatic valve 32, 33 to the vacuum source, and the holder is spring-raised clear of the bottle B, which continues on its straight path X<SP>1</SP>-X<SP>1</SP> along the conveyer 4. With continued rotation of the starwheel, the notch 23 picks up another cap C &c. Plastics bottles.-The plastics bottles B, Fig. 1, are shaped as shown, with a lower part 1 of reduced diameter and a narrowed waist 2.

IPC: C08B11/08
Filed: 1930-01-30
Abstract: Mixed ethers are produced by acting upon alkali cellulose with a mixture of a simple or a substituted alkyl, alkylene or aralkyl halide and ethylene oxide or a homologue thereof, if desired in the presence of a diluent and a catalyst.  In an example, 1 molecule of alkali cellulose is mixed with 6 molecules of benzyl chloride and 1 molecule of ethylene oxide in an autoclave heated to 50 DEG  C.; the temperature rises to 120 DEG  C. and is maintained for 2-3 hours. After disappearance of fibres, the mass is cooled and kneaded and extracted with ethanol to remove excess of benzyl chloride, and is then washed with water.  The benzyl-oxyethyl-cellulose obtained is soluble in chloroform, diethylenoxide and benzene, but insoluble in benzine, ethanol, methanol and ether.  In further examples, benzyl-oxybutyl-cellulose, and propyl-oxyethyl-cellulose are similarly obtained.  Chlorbenzene is instanced as a diluent and dimethylaniline as a catalyst.  The invention is distinguished from two-stage processes involving (1) further etherification of alkyl cellulose by ethylene oxide or its homologues, and (2) alkylation of oxyalkyl ethers obtained by treating cellulose with ethylene oxide.
