An internally screw-threaded ferrule is screwed on to a metal braided hose, and then an externally screw-threaded nipple is screwed into the hose bore, so as to expand the hose into engagement with the ferrule. If the braiding of the hose is embedded in rubber the end of the hose is first turned to remove the rubber and expose the braiding. A machine for carrying out this operation comprises a support 11, Figs. 1, 2, a clamp 16, 18 for the hose, slidable on rods 12, and a self centring chuck 47 for gripping and rotating the ferrule, the nipple, or the tool for removing the rubber from the end of the hose. Clamping jaws 16, 17 of the hose clamp, are actuated by a handle 34, Fig. 2, which rotates left and right handed lead screws 24 through pinions 29-32. Chuck 47 is rotated by a reversible electric motor 41, Fig. 1, through gear-boxes 39, 35. The output shaft of gear-box 35 is splined, so that the chuck can be moved axially by a lever 52, which moves a slide 50 having an arcuate member 48 engageable with a circumferential groove formed on the chuck. Chuck 47 has two sets of jaws 53, 54, shaped to fit the ferrule and the nipple. In a modification, gear-box 39, Figs. 3, 4 (not shown), is attached directly to gear-box 35, and motor 41 is disposed at one side of gear-box 39. To remove the rubber from the end of the hose, the latter is clamped by jaws 16, 17, a tool is gripped in the chuck and rotated, so that a spiral is formed along the outside of the rubber, whereafter another part of the tool severs the base of the spiral and strips the rubber from the braiding.

Filed: 1964-12-09
Abstract: 1,024,528. Gyratory crushers. KLOCKNERHUMBOLDT-DEUTZ A.G. Dec. 9, 1964 [Dec. 11, 1963], No. 50064/64. Heading B2A. [Also in Division F2] The head 4 of a gyratory crusher rests on a hollow piston 25 containing a gaseous pressure medium and slidable in a hydraulic cylinder 24 located in the bore of a spindle 14, the piston 25 being closed at the bottom, to form a compartment 26, by a piston 28 below which is a non-return valve 29 secured to the piston 25, the space 38 below the valve being in communication with a pipe 39 secured to a liquid-pressure pump 40 in turn connected by a pipe 41 to a reservoir 42. In addition, the pipe 39 is connected through a cut-off valve 43 and pipe 44 to the reservoir 42. The valve comprises a spring- influenced seat 32 and a passage 35 adjustable by a set screw 36. The piston 28 may be replaced by a bladder filled with gaseous pressure medium. When an uncrushable body enters the crushing gap, the piston 28 and valve 29 are caused to move downwards and pressure liquid enters the valve and presses against the piston 28. As a result, the piston 28 moves upwards compressing the gaseous medium in the piston comparment 26. After the cause of overloading is removed, the pressure of the medium in the compartment 26 pushes the piston 25 upwards to its initial position. In the course of this, the pressure liquid forced into the space between the piston 28 and the valve 29 flows back into the compartment 38 until the piston 25 and hence the head 4 have been urged back into their initial positions. If it is desired to alter the width of the crushing gap, pressure liquid is supplied to or withdrawn from the compartment 38.

As described with regard to a machine vending articles at 18 cents, inserted coins are tested, then trip coin switches, and finally drop into coin tubes (11), (12), (see Fig. 1, not shown), or a cash box. Coin pay-out.-A pair of tubes (11), (12) are mounted above a fixed plate 15 (Fig. 2) so that a pile of nickels is supported on plate 15 through an aperture 30 of a plate 13, and a pile of dimes passes through an aperture 33 in the plate 15 and an aperture 32 in a plate 14 to rest on a fixed plate 16. Rotation of plate 13 about a pivot 25 slides a nickel until it drops through apertures 31 and 23 to a nickel delivery shoot; rotation of plate 14 slides a dime until it drops through apertures 16a, 22 to a delivery shoot. Plates 13 and 14 carry respective posts 34, 35 that cooperate with respective apertures 50, 54 (Fig. 3) in a pair of links 36, 37. The links 36, 37 are oscillated by respective cams 43, 46 and springs 51, 55 to produce rotation of the plates 13, 14 (Fig. 2) in response to a motor 49 (Fig. 3). Locking means.-A neck 56 in the link 36 co-operates with a T-shaped aperture 58, 59 in a keeper 39; a neck 57 in link 37 co-operates with a keeper slot 60. Energization of a solenoid 62 raises the keeper 39 to align the T-leg 59 with the neck 56, and so immobilize the link 36; simultaneously, the neck 57 is freed from the keeper slot 60, to free the link 37 for movement by the cam 46 and for dime delivery. Deenergization of the solenoid 62 drops the keeper 39 to relock the link 37, but to free the link 36 for nickel delivery by aligning the T-bar 58 with the neck 56. Change-giving.-An inserted quarter closes a switch to initiate vending, energize the solenoid 62 and activate the motor 70, resulting in a delivery of a dime as change (for a 15 cent article). Alternatively, the second of two inserted dimes closes a switch to initiate vending and activate the motor 70, the solenoid 62 remaining unenergized; a nickel is thereby delivered as change.
