Abstract
Abstract A device adapted to be fastened to slab saws or the like for holding stones or similar objects during cutting, said device comprising a generally vertical back plate, a pair of horizontal, spaced support arms extending outwardly from the back plate and adapted to cradle the object being cut, and a hold-down member pivotally connected to the back plate avove the support arms and including a pair of spaced fingers in biased engagement with the object to be cut to hold it firmly in place.

Claim 1
Independent Claim
207 words
For use with a cutting saw or the like, a device for holding generally spherical objects for cutting, said device comprising a relatively rigid, generally vertical back plate with a slot formed therein for the passage of a cutting blade, a pair of spaced, oppositely disposed support arms attached to and extending outwardly from said back plate on opposite sides of said slot such that the space between said support arms is coextensive with said slot, said support arms extending codirectionally and being perpendicular to said back plate, and including oppositely inclined surfaces which cradle the object to be cut, and means connected to said back plate for holding the object to be cut against said inclined surfaces, the holding means comprising an element pivotally connected to said back plate and means acting on the element for biasing same toward the support arms, said element being bifurcated to define a pair of hold-down fingers adapted to engage the upper regions of the object to be cut while bracketing a cutting blade, the fingers both being arranged adjacent the cutting blade and defining a space between the fingers substantially in alignment with said slot, each of the fingers being arranged opposite a respective one of the support arms.

Claim 3
Dependent Claim
29 words
The structure set forth in claim 1 wherein said biasing means influences the object to be cut in a direction against both said back plate and said support surfaces.
Claim 4
Dependent Claim
39 words
The structure set forth in claim 2 wherein each of said inclined surfaces comprises a generally planar surface perpendicular to said back plate, and each of said arms is comprised of an angle iron welded to said back plate.
Claim 5
Dependent Claim
102 words
The structure set forth in claim 1, wherein the holding means further includes a stationary hinge member and a movable hinge member, the stationary member affixed to the back plate, and a hinge pin pivotally mounting the movable hinge member on the stationary hinge member, and the element being substantially rigid and pivotally mounted on the movable hinge member for movement toward and away from the support arms, and arranged for accommodating objects of different size and configuration, and wherein the biasing means includes a coil spring connected between the hinge members and arranged for biasing the element toward the support arms.
Claim 6
Dependent Claim
102 words
The structure set forth in claim 3, wherein the holding means further includes a stationary hinge member and a movable hinge member, the stationary member affixed to the back plate, and a hinge pin pivotally mounting the movable hinge member on the stationary hinge member, and the element being substantiaLly rigid and pivotally mounted on the movable hinge member for movement toward and away from the support arms, and arranged for accommodating objects of different size and configuration, and wherein the biasing means includes a coil spring connected between the hinge members and arranged for biasing the element toward the support arms.
Claim 7
Dependent Claim
20 words
The structure set forth in claim 5, further including means connected to the back for being clamped in a vise.
