A machine for driving glazier's and framer's points utilizes a push plate which is effective to drive the points at both of two levels. A ramp element is incorporated, which serves to deflect the points from an upper to a lower level as they are being driven forwardly into the workpiece, and edge features of the points employed impart a rotation or turning action thereto which deflects the tail portions downwardly to bear tightly upon the glass plate or other piece that is being mounted. Features of the points cooperate with elements of the magazine to ensure proper orientation, and the machine is effective and comfortable to use.

A machine for cutting a sheet material incorporates a system for clamping the sheet material against an underlying support surface, which system employs linear arrays of clamp units, each unit including a separate clamping member having a head portion with a flat top surface and a peripheral element constructed to engage an edge portion of the sheet material. The clamping members are disposed in spaced relationship along marginal portions of the support surface, an actuator is proveded for effecting movement of the clamping members between release and clamp positions. Because of the construction of the clamping members, the top surfaces thereof will be substantially flush with the surface of the clamped material being cut, thus enabling a cutting head having an associated glide plate to pass thereover, in contact therewith, without substantial interference or impediment.

A mechanism is provided for circumscribing oval paths, wherein a pivotably mounted element is dynamically oriented so as to maintain a functional axis thereof constantly tangent to the circumscribed path. An orienting arm attached to the mounted element is arcuately reciprocated by an element moving unidirectionally in a circle, the direction of circular movement being opposite to that in which the mounted element proceeds.

A mat cutting machine utilizes a trolley which runs smoothly and accurately along a shaft mounted upon the clamping bar assembly. Means is provided for precisely adjusting the relationship between the bevel cutting blade and the edge of the clamping bar, and the blades are held by magazines which permit ready interchangeability and facile adjustment of the amount of blade protrusion so as to enable the cutting depth to be altered with considerable ease. The base of the machine includes means for accurately positioning the workpiece, and for readily controlling the travel of the trolley, to afford high volume production capability.

A mat cutting machine utilizes a trolley, which runs smoothly and stably along a shaft mounted upon the clamping bar assembly, the head assembly of the trolley including eccentric means for precisely adjusting the relationship between the cutting blade on the bevel side and the edge of the clamping bar.

A system for clamping sheet material against an underlying support surface employs linear arrays of clamp units, each unit including a separate clamping member having a head portion with a flat top surface and a peripheral element constructed to engage an edge portion of the sheet material. The clamping members are disposed in spaced relationship along marginal portions of the support surface, and an actuating device is providing for effecting movement of the clamping members between release and clamp positions. The cutting head utilizes a blade magazine-mounting slide, the travel of which is positively limited and which has a unique pin arrangement for facilitating the interchange of separate magazines adapted for specific cutting modes.

A turret assembly for a cutting head has a glass-cutting wheel and a plastic-cutting blade portion disposed at spaced peripheral locations. Rotation of the turret body brings the cutting elements into their operative positions, and cooperating detent elements ensure reliable indexing of the turret and proper orientation of the leading edge of the plastic-cutting blade portion.

A machine is provided for cutting oval shapes in planar workpieces, wherein the blade is dynamically oriented so as to maintain its cutting axis constantly tangent to the line of cutting. It utilizes a pivotably mounted cutter head, to which is attached an orienting arm that is arcuately reciprocated by an element moving unidirectionally in a circle, the direction of circular movement being opposite to that in which the cutting head proceeds.

A push-pull DIY cutter for sheet material, such as mat and foam board, utilizes a blade-mounting handle that is pivotable from a null position in both of two opposite directions, so as to alternatively bring into operative position a blade element spaced to either side of the null position center line. The blade is mounted for lateral shifting, so as to cause the elements on its opposite ends to protrude to a greater or lesser extent from either side of the cutting head. Indicia are provided along the lower boundary of the head to facilitate adjustment of the blade for optimal protrusion of the blade element that is to be utilized in any given instance.
