Abstract
487,981. Cow-milkers ; supporting pipes. AKTIEBOLAGET SEPARATOR. June 29, 1937, No. 18055. Convention date, June 29, 1936. [Class 84] [Also in Group XXVIII] A milking-machine installation comprises a releaser 7 and a milk pipe 8 which extends from the milking unit or units of the installation to the releaser and includes a number of parts secured axially in pushfit connection in which they are held in engagement by axially directed pressure applied at the outer end of the pipe so that they can be dismounted from their supports and from each other without using tools. As shown, the milk pipe 8 and the vacuum pipe 6 consist each of a number of straight tubes interconnected with one another and with the milking units by T-tubes mounted on fixed holders, the parts being held in engagement by locking means consisting of a part 22, Fig. 5, which is pressed by a weight-loaded lever 23 against plugs 24, 25 closing the free ends of pipes 6, 8. The part 22 is pivotally connected to plug 25 which has two projections 26 engaging a flange 27 on the T-tube 28 whereby parts 22, 25 are secured to the tube when lever 23 is raised for the dismantling of pipe 8. The T-tube 28 is connected to a fixed holder 29 by a bayonet-like connection including a lock-ring 30 preventing unintentional removal of the T-tube 28 from holder 29. The pipes 6, 8 are pressed against a support 31, Fig. 1, and the parts thereof between support 31 and releaser 7 are held in position by wing nuts &c. The vacuum pipe 6 is connected by a T-tube 32, Fig. 6, to an equalization vessel 5 which is connected by a pipe 3 to a vacuum pump 1. The T-tube 32 is supported so that it can be moved in the axial direction of pipe 6 by a holder 33 which consists of a base portion 34 having two hooks 35 affording a support in an upward direction for pipe 6, the weight of which is balanced by that of vessel 5. At each milking point a pulsator 9 is provided which sends pulsating vacuum through pipe 10 to the teat cups 11 from which the milk flows through pipe 12 to pipe 8. Near the releaser 7 the pipe 6 has a pulsator 14 which generates pulsations in the lower chamber 17, Fig. 4, of the releaser to which it is connected by pipe 15. The milk pipe 8 extends into the upper chamber 16 of the release where it is provided with a number of holes, one or more of which are downwardly directed irrespective of the angular position of the pipe. The milk flows from chamber 16 which is under constant vacuum through a valve consisting of a body 19 having a downwardly projecting flange 20 seating in an annular pocket 21 in the housing and forming a liquid seal to the lower chamber 17 when this is under vacuum. In the alternate phase, when chamber 17 is under atmospheric pressure, the milk discharges therefrom through a flap valve 18. The pulsators are driven by impulses from a common electric circuit and are arranged so that pulsator 14 is generating a vacuum in pipe 15 when pulsators 9 convey atmospheric pressure to the teat cups to equalize the load on the vacuum pump 1. Reference has been directed by the Comptroller to Specification 460,401.
