Abstract
Abstract Apparatus for coating articles with a viscous liquid in such a way that the viscous liquid coats the sides and bottoms of said articles but not the tops thereof. Objects are carried on a conveyor through openings in a free-falling curtain of the liquid, which openings are caused by placing flow-interrupting means above the liquid-discharging wall of a dam-type liquid dispenser. The vertical position of these interrupting means is selected to assure the cohesive forces of the viscous liquid will close the openings proximate the surface of the conveyor, i.e., proximate the bottom of said objects to be coated. Thus the lower portions of the articles are conveyed through the closed bottom of the curtain openings, and receive coating therefrom while the upper portions of the articles ride through the openings uncoated.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
62 words
maintaining the distance between the top of said curtain and the bottom of said articles so that the cohesive forces of the liquid form converging streams which close said opening at a point proximate the bottom of said objects and form a coating deposit through which the lower portions of said articles must pass while the top of said articles remains uncoated.
Claim 2
Dependent Claim
32 words
The article-coating apparatus of claim 1, wherein said flow-interrupting members are pins upstanding above the level of the lip of said dispenser to split the flow of said liquid over said lip.
Claim 3
Dependent Claim
43 words
The article-coating apparatus of claim 2, wherein said flow-interrupting members are pins, upstanding above the level of said lip, and pivotally carried on a transverse shaft, said pins being selectively pivotable out of the path of said liquid when split-flow is not required.
Claim 4
Dependent Claim
42 words
The article-coating apparatus of claim 1, wherein said flow-interrupting members are cylindrical pins, and said apparatus includes a set of hollow cylindrical sleeves of different diameter, each fitting over a pin to increase the diameter thereof for increasing the split caused thereby.
Claim 5
Dependent Claim
37 words
The article-coating apparatus of claim 4, wherein said flow-interrupting members are upstanding pins removably positioned in a bar and wherein said bar includes a slot for removably positioning the same on the lip of said dispensing means.
Claim 6
Dependent Claim
53 words
The article-coating apparatus of claim 5, wherein said bar includes a plurality of spaced holes, flow-interrupting pins placed in said plurality of holes, and a slot extending the full length of the bottom of said bar into which said lip of said dispensing means may fit, thereby holding said bar in operating position.
Claim 7
Dependent Claim
35 words
A process for coating candy articles with a viscous chocolate liquid whereby the top of said articles remains uncoated, but the lower portion of the sides of the articles become coated, comprising the steps of:
Claim 8
Dependent Claim
159 words
In a chocolate-coating machine of the type having an endless foraminous conveyor advancing plural lines of uncoated fillings along a longitudinal path through a laterally extending liquid curtain of viscous coating, the combination of: a laterally extending dispensing tray of viscous coating mounted above said path with the lip of the front wall thereof normally adapted to create an unbroken liquid curtain of said coating for completely covering the fillings in each line advancing therebelow, and flow-interrupting means, removably associated with said lip, said means including at least one pin upstanding above the level of said lip, in the path of viscous liquid flowing thereover, and arranged to split said flow to form an opening in said curtain through which the upper portion of a filling may pass without deposit of coating on the top thereof, while forming a closure deposit of said coating at the bottom of said opening, through which the lower portion of said filling passes.
