Abstract
Abstract A pattern duplicating apparatus including a large rigid frame suspended by trolleys from an I-beam and carrying longitudinally spaced tracer and cutter assemblies. The frame is manually displaceable linearly in the longitudinal and vertical directions and pivotally about the longitudinal axis. The frame suspension includes interconnected sprockets and chains to ensure a pure rectilinear vertical displacement.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
116 words
A pattern duplicator comprising: a rigid, manually displaceable frame including a pair of longitudinally spaced vertical members and means rigidly connecting the members, said frame being adapted for overhead, vertical suspension and having a longitudinal axis, tracer means depending from the frame at one longitudinal end thereof, pattern stock cutter means depending from the frame at the other longitudinal end thereof, and overhead support means for vertically suspending the frame relative to a work surface, the support means permitting linear displacement of the frame along longitudinal and vertical axes and pivotal displacement about the longitudinal axis, said overhead support means including telescopic means for permitting vertical displacement of the vertical members in unison with one another.
Claim 2
Dependent Claim
116 words
A pattern duplicator comprising: a rigid, manually displaceable frame including a pair of longitudinally spaced vertical members and means rigidly connecting the members, said frame being adapted for overhead, vertical suspension and having a longitudinal axis, tracer means depending from the frame at one longitudinal end thereof, pattern stock cutter means depending from the frame at the other longitudinal end thereof, and overhead support means for vertically suspending the frame relative to a work surface, the support means permitting linear displacement of the frame along longitudinal and vertical axes and pivotal displacement about the longitudinal axis, said overhead support means including telescopic means for permitting vertical displacement of the vertical members in unison with one another.
Claim 3
Dependent Claim
38 words
A pattern duplicator as defined in claim 1 wherein said means rigidly connecting the members includes a pair of diagonal members defining an A-shaped opening to facilitate the addressing and manual grasping of the frame by an operator.
Claim 4
Dependent Claim
33 words
A pattern duplicator as defined in claim 1 wherein the tracer means is carried by one of the vertical members and the cutter means is carried by the other of the vertical members.
Claim 5
Dependent Claim
37 words
A pattern duplicator as defined in claim 3 including means for permitting the tracer means and the cutter means to be oriented relative to the vertical members at each of several angular displacements about a longitudinal axis.
Claim 6
Dependent Claim
64 words
A pattern duplicator as defined in claim 4 wherein the means for permitting said orientations includes at each longitudinal end of the frame a plate secured to the lower end of the vertical member and having a plurality of arcuately arranged holes, a support member pivotally connected to the plate and including pin means for locking the support member to each of the holes.
Claim 7
Dependent Claim
24 words
A pattern duplicator as defined in claim 1 wherein the stock cutter includes a motor and a rotary cutting blade carried by the frame.
Claim 8
Dependent Claim
31 words
A pattern duplicator as defined in claim 1 wherein the overhead support means includes at least one trolley for permitting free displacement of the frame along a longitudinally aligned overhead beam.
Claim 9
Dependent Claim
51 words
A pattern duplicator as defined in claim 1 wherein the telescopic means includes a pair of longitudinally spaced sprockets fixed over the frame, a pair of chains connected to the frame and engaging the sprockets for rotation thereof during vertical displacement and means interconnecting the sprockets to ensure unison rotation thereof.
Claim 10
Dependent Claim
18 words
A pattern duplicator as defined in claim 8 including a counterweight connected to the chains and suspended thereby.
Claim 11
Dependent Claim
38 words
A pattern duplicator as defined in claim 1 wherein the overhead support means includes a pair of longitudinally spaced vertical brackets for receiving the vertical members, and pin members for pivotally connecting the vertical members to the brackets.
Claim 12
Dependent Claim
21 words
A pattern duplicater as defined in claim 1 including a platform disposed vertically beneath the frame for supporting the pattern stock.
