Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
269 words
A window shade roller assembly adapted for use in a standard window shade cutting machine wherein said machine includes a support base having an elongated support and measuring bed for a window shade roller assembly, means for fixing one end of a window shade assembly to said base, a housing for receiving the other end of the assembly mounted on the opposite end of said support base and having an internal bore, a beveled mouth at the forward end of said internal bore, a retractable chuck mounted within said bore, and means for retracting said chuck; said assembly comprising a tubular roller member having an external diameter larger than the diameter of said bore, an end plug having a peripheral flange having a maximum dimension less than the diameter of said bore, and a minimum dimensiOn greater than the internal diameter of the tubular roller member, a gudgeon pin fixed into said plug to project fron one side thereof externally of said roller member, said plug also having a reduced diameter portion adjustably received within the interior of said tubular roller member, said reduced diameter portion having exterior peripheral projections engaging the inner wall of said roller member to retain said plug against rotation relative to the roller member at any one of several selected positions of axial adjustment, said chuck being engageable with said gudgeon pin to telescopically axially pull said plug from said roller member as said chuck is retracted into said bore, any consequent movement of said roller member being prevented by abutment of the end of said roller member with the mouth of said housing.
Claim 2
Dependent Claim

A window shade roller assembly adapted for use in a standard window shade cutting machine wherein said machine includes a support base having an elongated support and measuring bed for a window shade roller assembly, means for fixing one end of a window shade assembly to said base, a housing for receiving the other end of the assembly mounted on the opposite end of said support base and having an internal bore, a beveled mouth at the forward end of said internal bore, a retractable chuck mounted within said bore, and means for retracting said chuck; said assembly comprising a tubular roller member having an external diameter larger than the diameter of said bore, an end plug having a peripheral flange having a maximum dimension less than the diameter of said bore, and a minimum dimensiOn greater than the internal diameter of the tubular roller member, a gudgeon pin fixed into said plug to project fron one side thereof externally of said roller member, said plug also having a reduced diameter portion adjustably received within the interior of said tubular roller member, said reduced diameter portion having exterior peripheral projections engaging the inner wall of said roller member to retain said plug against rotation relative to the roller member at any one of several selected positions of axial adjustment, said chuck being engageable with said gudgeon pin to telescopically axially pull said plug from said roller member as said chuck is retracted into said bore, any consequent movement of said roller member being prevented by abutment of the end of said roller member with the mouth of said housing.
Claim 3
Dependent Claim
48 words
The window shade roller assembly of claim 1 wherein the peripheral projections of said plug of said roller assembly define interrupted helical threads and the plug has means external to said flange for rotating said plug to axially adjust the position of said plug in said roller member.
Claim 4
Dependent Claim
43 words
The window shade roller assembly of claim 2, wherein said end plug includes a generally eliptical extension, opposite said reduced diameter portion, having opposed flat surfaces permitting receipt of a tool for axial adjustment of the end plug in said tubular roller member.
