A novel mounting assembly for use with a universal woodworking tool support system is the subject of the invention. First and second straight elongated support stanchions are received by tubular members of the universal tool support system. A scroll saw is mounted on top of these two straight stanchions. A drive train includes an eccentric drive for reciprocating the scroll saw arms and a concentric mass between the eccentric drive and the output of the prime mover is part of the universal tool ...

The device for cutting blocks of granite, marble, stone and other like materials by means of diamond blades displaced in a reciprocating movement by a blade carrying frame, said blade carrying frame being itself connected to a reciprocating motor unit, characterized in that at least the blade carrying frame is connected to a sliding frame by means of vibration damping means.

A trim press for severing articles differentially pressure formed in a thermoplastic sheet comprising a stationary die member and a movable trim die member mounted on a frame for movement toward and away from the stationary trim die member between a spaced apart position and a closed position in which the trim die members engage opposite sides of a sheet to sever the article from the sheet. Dynamically balanced drive mechanism is provided for moving the platen in a to-and-fro path of travel whil...

A scroll saw has a base including integral walls forming a gear casing, a frame assembly mounted on the base, and lower and upper oscillating arm members pivotally mounted on the frame assembly. The gear casing houses gear and counterweight assemblies for driving and counterbalancing the oscillating motion of the lower and upper arm members. A saw blade is removably mounted between corresponding free ends of the lower and upper arm members. The ends of the saw blade are prepositioned between a p...

An equilibrium apparatus of cut-off mechanism for high-speed nut former which includes a cutting unit carrying a cutting tool thereon, and a counterweight unit carrying a counterweight unit thereon. The cutting unit and the counterweight unit are connected pivotally to a coupling unit which is fixed on the machine table of the nut former at the central portion thereof so that the cutting unit and counterweight unit are capable of effecting straight motion. A push plate is drivable to move in a f...

A scroll saw is disclosed having a yoke with upper and lower reciprocable arms terminating in upper and lower ends having a saw blade connected therebetween. A motor, with a horizontally extending drive shaft, is mounted on the base for the saw. A connecting rod is coupled eccentrically at one end to the drive shaft and at the other end to the lower arm of the yoke. A second shaft is rotatably mounted on the base parallel to the drive shaft and is driven by intermeshing gears on the shafts. Firs...

A horizontal disc is supported on an arm on a portable saw mill carriage in a plane such that the disc is arranged to follow a horizontal saw kerf to provide vertical stabilization between a log and a carriage. Also a foot is mounted on an arm and is arranged to engage the face portion of a log to provide lateral stabilization. This arm is laterally adjustable for locating it according to the depth of cut. Furthermore, a hold-down wheel assembly is supported on a link which is urged downwardly t...

The present invention is related to a stepless transmission scroll sawing machine with saw blade fastening and micro-inch adjusting device and the related positioning device and, more particularly to a scroll sawing machine which includes a carbon brush motor controlled by means of a control circuit to drive an eccentric plate to carry the saw blade control arms to make an up-and-down reciprocating motion so as to perform sawing process, wherein a saw blade fastening and micro-inch adjusting dev...

The machine tool comprises a frame (1, 2, 3) with two fixing elements (22 and 39) for fastening a scroll saw blade. The fixing element (22) is driven by an electrical motor (5) in a vertical reciprocating movement. The two fixing elements (22 and 39) are linked to each other by a metallic ribbon (45) passing on pulleys (46 to 50). The position of the pulley (47) can be changed by means of a cam (53) acting on an arm (52) so as to stretch the ribbon (45) to the desired value.

This invention relates to gang saws and other cutting apparatus having oscillating cutters for cutting workpieces into slices. The invention provides apparatus, having two elongate spaced apart cutter supports which are driven to oscillate 180.degree. out of phase with each other. Two sets of cutters are connected to the supports. For a suitable workpiece the cutters may be of a hot wire type. Each cutter of one set is connected to the first support by a resiliently extensible connector such as ...
