Abstract
Abstract An improved mounting base is disclosed which gives added flexibility to a universal tool such as a radial saw. Included in this mounting base is an indexing turntable having a center beneath the operating range of the tool. A hinge arrangement is available to bring the turntable with the tool thereon to a position at 90* to the vertical. The radial arm thus becomes a vertical ways and with the addition of a biased lever to the motor unit, provides an efficient vertical drill press.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
176 words
In a universal radial saw tool, a base, a column extending from and supported by said base, a horizontal ways adjustably supported on said column, a movable carriage mounted on said horizontal ways for supporting a motor assembly with attachments to support simultaneously a radial saw and a drill chuck with the portion of the motor assembly which supports said chuck being positionable in a direction toward said column, the improvement comprising a table assembly consisting of a frame, and a top for said frame, said top consisting of two portions, means for pivotally attaching said portions together, means for rotatably securing one of said portions to said frame, a turntable means pivotally mounted on the other of said portions, means for attaching said base to said turntable means, whereby said base, said column, and said horizontal ways can be selectively positionable relative to said frame, with said horizontal ways assuming a vertical position so that when said drill chuck is positioned toward said column, said drill chuck can be used as a vertical drill press.
Claim 2
Dependent Claim
176 words
In a universal radial saw tool, a base, a column extending from and supported by said base, a horizontal ways adjustably supported on said column, a movable carriage mounted on said horizontal ways for supporting a motor assembly with attachments to support simultaneously a radial saw and a drill chuck with the portion of the motor assembly which supports said chuck being positionable in a direction toward said column, the improvement comprising a table assembly consisting of a frame, and a top for said frame, said top consisting of two portions, means for pivotally attaching said portions together, means for rotatably securing one of said portions to said frame, a turntable means pivotally mounted on the other of said portions, means for attaching said base to said turntable means, whereby said base, said column, and said horizontal ways can be selectively positionable relative to said frame, with said horizontal ways assuming a vertical position so that when said drill chuck is positioned toward said column, said drill chuck can be used as a vertical drill press.
Claim 3
Dependent Claim
28 words
In a universal radial saw tool as recited in claim 1, wherein the means for pivotally attaching said portions of said top together consists of a piano-type hinge.
Claim 4
Dependent Claim
27 words
In a universal radial saw tool as recited in claim 1, wherein said vertical drill press has an adjustable height adjustment to limit movement of said press.
Claim 5
Dependent Claim
43 words
In a universal radial saw tool as recited in claim 1, wherein said one of said portions of said top of said frame is horizontally disposed to receive said tool and having a block thereon adapted to engage said column of said tool.
Claim 6
Dependent Claim
54 words
In a universal radial saw tool as recited in claim 1, wherein said turntable means is circular in shape, and indexing means on the other of said portions of said top of said frame for selection of increments of rotary positioning of said turntable means by engagement of the periphery of said turntable means.
Claim 7
Dependent Claim
33 words
In a universal radial saw tool as recited in claim 1, and means located on said one of said portions of said top on said frame to limit rotation of said one portion.
Claim 8
Dependent Claim
54 words
In a universal radial saw tool as recited in claim 1, and additionally clamp-on means including a clamp positioned adjacent said horizontal ways, a lever pivoted to said clamp, and a spring opposed pushrod connecting said clamp with said motor assembly carriage, whereby said vertical drill press adaption may be sensitively controlled in operation.
Claim 9
Dependent Claim
39 words
In a universal radial saw tool as recited in claim 7, a gauge comprising a slotted member and a thumbscrew for securing said slotted member adjustably to said lever in the sliding path of the said motor assembly carriage.
Claim 10
Dependent Claim
99 words
In a universal radial saw recited in claim 8, said clamp comprising a longitudinally slotted strap having an ear at right angles thereto and a hook-shaped member pivotally affixed thereon spaced from the ear; a slide having an integral ear corresponding to the first said ear, and integral oppositely facing hook-shaped members for opposing the first said hook-shaped member; a bolt adjustably connecting the said ears to lock said clamp on said horizontal ways, and a second bolt connecting said slide to the slotted strap at the said slot, said clamp means being vertically adjustable on said horizontal ways.
