464,687. Filling milk bottles. DAIRY ACCESSORIES CO., Ltd., MARTIN, E. A., and CADMAN, E. A. Oct. 21, 1935, No. 28944. [Class 125 (ii)] In apparatus for filling milk bottles or like receptacles from a container having a valve opened by upward pressure by the. mouth of the receptacle which is lifted by a yoke adapted to embrace the neck or top portion thereof and bear upwardly against a rim at the mouth thereof, the yoke comprises two side ledges over which the rim or tapering portion of the receptacle engages by lateral movement of the receptacle. A milk container A mounted on stand B has valves C comprising an inner shell c forming part of a fitting c<4> in the bottom of the container, and a valve c<1> mounted on a stem c<2> secured to a bridge c<3> also secured to fitting c'. An outer shell c<5> slides over shell c and is urged downwardly by spring c<6>. At its bottom is a seating to engage valve c<1>. A rubber seat around the bottom of shell c<5> receives the mouth of the bottle, which, moving upwardly, lifts the housing from the valve and permits milk to flow from the receptacle. A yoke D has a hole d large enough to receive the mouth of the bottle E, with ledges d<1> at its forward part to bear upwardly against the rim e of the bottle mouth. The yoke forms the forward part of a lever F pivoted at f to a transverse bar G. A rearward extension f of the lever is engaged by cam H on shaft h rotatable by handle h<1>. A pair of valves is provided, so set that when one yoke is lifted to open its valve the other is down. Thus a full bottle is removed and replaced by an empty one while another bottle is filling. In a modification the lever F has a forward extension fitted with a handle passing through a guide slot in a plate secured to the underside of the container A. A notch at the top of the slot permits the handle to be secured in the raised position, while a bottle is being filled. A modified form of yoke is open at one side to permit lateral insertion of the bottle and a plate is provided as a register against which the mouth of the bottle may be held to ensure the engagement of the rim e over the ledges d<1>. Instead of mounting the yokes on levers they may be guided for vertical movement and actuated by a cam. The Provisional Specification describes also a support for bottles not adapted for support by means of a yoke and a slightly modified form of lever for lifting the bottles against the valves.
