Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
146 words
In an apparatus for cleaning records and pickup styli, including a hollow housing (22) containing at one end a chamber (38), the upper portion of the other end of said housing containing an opening (36) communicating with said chamber for slidably receiving the handle portion (40) of a stylus brush (14), said stylus brush having an extension portion (44) which is adapted to extend within said chamber and which carries upwardly extending stylus-cleaning bristles; record cleaning means (28, 12) carried by the bottom portion (18) of said housing; and an open-topped trough-shaped closure member (16) connected with the bottom portion of said housing to enclose said record cleaning means; the improvement which comprises support means (68; 80, 82, 88) connected with the bottom wall of said chamber for supporting the extension portion of the stylus brush when the stylus brush is inserted within the housing opening.
Claim 2
Dependent Claim
146 words
In an apparatus for cleaning records and pickup styli, including a hollow housing (22) containing at one end a chamber (38), the upper portion of the other end of said housing containing an opening (36) communicating with said chamber for slidably receiving the handle portion (40) of a stylus brush (14), said stylus brush having an extension portion (44) which is adapted to extend within said chamber and which carries upwardly extending stylus-cleaning bristles; record cleaning means (28, 12) carried by the bottom portion (18) of said housing; and an open-topped trough-shaped closure member (16) connected with the bottom portion of said housing to enclose said record cleaning means; the improvement which comprises support means (68; 80, 82, 88) connected with the bottom wall of said chamber for supporting the extension portion of the stylus brush when the stylus brush is inserted within the housing opening.
Claim 3
Dependent Claim
19 words
Apparatus as defined in claim 1, wherein said support means is in frictional engagement with the stylus brush extension.
Claim 4
Dependent Claim
50 words
Apparatus as defined in claim 2, and further wherein the housing contains guide means (50) arranged or opposite sides of the opening (36) for engaging the lateral surfaces of the body portion (40) of the stylus brush to longitudinally guide the brush during the introduction thereof into the housing opening.
Claim 5
Dependent Claim
31 words
Apparatus as defined in claim 3, wherein said support means comprises a pair of laterally-spaced longitudinally-extending web elements (80, 82) for frictionally engaging the lateral surfaces of the stylus brush extension.
Claim 6
Dependent Claim
51 words
Apparatus as defined in claim 4, wherein each of said web elements terminates adjacent the free extremity of the stylus brush extension portion in a resilient tongue portion (84, 88), said tongue portions being biased inwardly toward each other into frictional engagement with the lateral surfaces of the brush extension portion.
Claim 7
Dependent Claim
90 words
Apparatus as defined in claim 3, wherein said support means includes a longitudinally extending vertical web (68) arranged beneath the brush extension portion, said vertical web having a leading upper surface (70) which is upwardly inclined in the direction of the free extremity of the stylus brush extension when the stylus brush is introduced into the housing whereby during the introduction of the stylus brush within the housing, the lower surface of the brush extension portion rides in frictional engagement with the inclined leading surface of the vertical support web.
Claim 8
Dependent Claim
50 words
Apparatus as defined in claim 6, wherein the upper surface of the vertical support web (68) terminates in a downwardly inclined trailing portion (74), the free extremity of the brush extension being in fractional engagement with said trailing web surface when the stylus brush is completely introduced into the housing.
Claim 9
Dependent Claim
35 words
Apparatus as defined in claim 3, wherein said support means (68) extends toward said other end of said housing at least to the guide means (50) which engage the lateral surfaces of the stylus brush.
Claim 10
Dependent Claim
54 words
Apparatus as defined in claim 7, wherein the brush extension portion (44) is arranged at an oblique angle to the body portion (40) of the stylus brush, said guide means (50) being parallel with the bottom portion (18) of said housing, and said support web trailing surface being parallel with the brush extension portion.
Claim 11
Dependent Claim
40 words
Apparatus as defined in claim 3, wherein said housing includes beneath the opening (36) means defining a longitudinal compartment (56) for receiving a second set of bristles carried by the lower surface of the body portion (40) of the brush.
Claim 12
Dependent Claim
41 words
Apparatus as defined in claim 1, wherein said housing is sectional, the bottom portion (18) of the housing carrying said support means (68; 80, 82, 88) comprising a bottom section that is removably connected with a top section of the housing.
