Manufactured by Hi-Tech Company - Kerrville TX

Latch mechanism for "snap-ring pliers" based on patent no. 4,280,265. "A convertible retaining ring pliers includes a pair of jaws and a pair of handles all rotatable independently about a common pivot. Each jaw includes a transverse bore spaced from and parallel to the pivot axis for receiving an elongated cylindrical latching pin. Each handle has an associated end plate disposed on one side of the jaws, the end plates having holes to selectively receive an end of a latching pin to selectively latch a jaw to a respective handle. The latching pin bores have elongated grooves and the latching pins have associated friction springs with projecting tabs coacting with those grooves to retain the pins within the assembled pliers. Elongated retaining ring tips have hexagonal shanks received in multi-sided jaw recesses to retain the tips against rotation and to enable selected rotational orientation of the tips. The convertible pliers includes a ratchet mechanism operative between the two handles to maintain the handles closed in a selected position against the load of the retaining ring." Both patent numbers appear on pliers produced by Hi-Tech Co. (Kerrville, TX).

Manufactured by H-Tech Compamy - Kerrville TX

"This invention relates to an improvement in pliers used to expand or contract the jaws, and is particularly suited to retaining ring pliers adapted to remove and secure snap rings and retaining rings in place. The pliers may be used to remove or replace retaining rings, fuses or small light bulbs and the like where space doesn't permit fingers to grasp same." Patent number appears together with 4,476,750 on snap ring pliers produced by Hi-Tech Co., Kerrville, TX.

Assigned to A. W. Stevens & Son - Auburn, Cayuga County NY

Abstract: The object of my invention is to provide means for more conveniently regulating or adjusting the pitch of the husking-rollers. Under certain conditions it is necessary to give a considerable angle to the husking-rollers, so that the ears will pass quickly off of the same. At other times it is desirable to have said rollers supported in a more nearly horizontal position, so that the ears may be retained longer upon the rollers to enable the latter to thoroughly strip the husks from the ear. In this class of machines it is customary to mount the husking-rollers in a frame which is pivot ally secured in the frame of the -machine at its upper end and is adjustable vertically at its lower end. The objection to this method of adjustment is that the frame holding the rollers, being separate from the frame of the machine, must be rigidly stayed to the machine-frame after it is adjusted. According to my invention the husking- rollers A are mounted in bearings supported directly by and in the main frame of the ma- chine, and I provide adjusting devices at the rear end of the machine for positively adjusting the machine-frame itself when it is necessary to adjust or vary the pitch of the husking-rolls. In this instance I have shown the rear end of the frame of the machine secured to its supporting-bolster B by a strap B', which is pivotally connected to the sill of the main frame at each side of the machine, these straps being so arranged as to permit the raising and lowering of the frame. Claim: In a cornhusking machine the combination with the main body of the machine and the husking-rollers mounted in bearings rigidly secured therein, of a supporting-truck for the machine including among its members a horizontal bolster adjacent to one end of said rollers, straps connected to said bolster and pivotally secured to the main body of the machine, and adjusting devices for raising the main body above said bolster, while leaving it connected therewith by said straps, to adjust said husking-rollers.

A "u" shaped clamping spring provides a nut gripping element on one side of the socket. To release the grip the pressure of the spring is released by an auxiliary lever. Some known examples matching this patent with the parts made of malleable castings have no visible markings. One known example has a partially visible date stamping.

Manufactured by Prentiss Vise Co. - Watertown, Jefferson County NY
Assigned to Prentiss Vise Co. - New York NY

Abstract: My invention has to do with vises for holding pipes or rods, and has been designed with to more particular reference to the needs of a vise for holding bicycle or other tubes or finished round bars. Under my invention the movable jaw of the vise-that is to say, that jaw which moves to and from the other-is actuated to move in a direction to clamp the work by means of what may conveniently be termed a "latch," adapted to engage the bar or stem which carries said jaw and capable both of an oscillatory or swinging movement by which it can be brought into and out of engagement with said stem and of a bodily movement lengthwise or in a direction to force the jaw to close tightly upon the work, in combination with means by which these several movements may be imparted to the latch. While I do not desire to be understood as limiting myself to the precise means hereinafter described for this purpose, yet I prefer to employ a pivoted lever-handle having an eccentric hub, upon which the latch is freely hung, the eccentricity of the hub determining the extent of longitudinal movement of the latch, while a pin or shoulder on the latch, against which the lever-handle brings up at a certain point in its movement, serves as a means by which the tilting or swinging of the latch is effected in a direction to disengage it from the stem, the latch being normally pressed by a spring in a direction to cause it to engage the stem. Claim: In a vise the combination with the movable jaw and the notched bar or stem carrying the same, of a lever-handle pivoted to the vise-body and provided with an eccentric hub, and a latch mounted freely upon said eccentric hub and adapted to engage and operate the notched stem.
