Abstract
Abstract A mechanical squeegee apparatus directed for use with and mounted on a stencil screen printing device. The apparatus includes a longitudinal support bar and a lateral support bar which is mounted for movement along the longitudinal bar and which extends transversely thereof and over said screen. A squeegee is mounted on the lateral bar for free movement along its length and for substantially free rotational movement relative to the lateral bar on an axis vertical and perpendicular to that of the lateral bar. The free lateral movement and the substantially free rotational movement allows the squeegee to be used to sweep ink from the side edges of the screen toward the center without the use of an intermediary device such as a hand-held card or scraper.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
141 words
A squeegee apparatus for use with a printing screen and frame therefor comprising a longitudinal support mounted on said frame, a lateral support bar mounted for movement longitudinally of said longitudinal support bar and extending transversely to said longitudinal support bar and over said screen, a squeegee blade assembly, comprising a squeegee blade having a longitudinal axis and attaching means for attaching said squeegee blade to said lateral support bar for free movement along said lateral bar and for substantially free rotative movement about an axis extending vertically and perpendicularly to said lateral bar, means attached to said squeegee blade assembly for directly moving said squeegee blade relative to said longitudinal support bar and to said lateral support bar in sweeping movements over said printing screen to force ink therethrough, and mounting means for mounting said squeegee apparatus on said frame.
Claim 2
Dependent Claim
141 words
A squeegee apparatus for use with a printing screen and frame therefor comprising a longitudinal support mounted on said frame, a lateral support bar mounted for movement longitudinally of said longitudinal support bar and extending transversely to said longitudinal support bar and over said screen, a squeegee blade assembly, comprising a squeegee blade having a longitudinal axis and attaching means for attaching said squeegee blade to said lateral support bar for free movement along said lateral bar and for substantially free rotative movement about an axis extending vertically and perpendicularly to said lateral bar, means attached to said squeegee blade assembly for directly moving said squeegee blade relative to said longitudinal support bar and to said lateral support bar in sweeping movements over said printing screen to force ink therethrough, and mounting means for mounting said squeegee apparatus on said frame.
Claim 3
Dependent Claim
22 words
The apparatus of claim 1 including wherein said means for directly moving said squeegee blade comprises a handle affixed to said assembly.
Claim 4
Dependent Claim
41 words
The apparatus of claim 1 and including a pivotal connection between said squeegee blade and said attaching means permitting relative pivotal movement between said squeegee blade and said attaching means along an axis parallel to the axis of said squeegee blade.
Claim 5
Dependent Claim
37 words
The apparatus of claim 1 wherein attaching means includes a framework, upper and lower bearing elements journaled in said framework, said lateral support bar having upper and lower surfaces engaged by said upper and lower bearing elements.
Claim 6
Dependent Claim
15 words
The apparatus of claim 4 wherein said upper and lower bearing elements are roller bearings.
Claim 7
Dependent Claim
39 words
The apparatus of claim 5 wherein said framework includes a pair of side walls, said roller bearings being journaled in said side walls, the distance between said side walls being greater than the cross-sectional width of said lateral bar.
Claim 8
Dependent Claim
43 words
The apparatus of claim 4 and including a first pivotal connection between said squeegee blade and said attaching means permitting relative pivotal movement between said squeegee blade and said attaching means along an axis parallel to the longitudinal axis of said squeegee blade.
Claim 9
Dependent Claim
27 words
The apparatus of claim 7 and including stop means on said attaching means for limiting said pivotal movement between said attaching means and said squeegee blade means.
Claim 10
Dependent Claim
38 words
The apparatus of claim 7 and including a second pivotal connection connecting said first pivotal connection to said attaching means, the axis of said second pivotal connection means extending transversely to the axis of said first pivotal connection.
