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.

Manufactured by C. H. Bidwell Thresher Co. - Batavia, Genesee County NY

Abstract: The object of my invention is the construction of a new and improved grain-scourer in io which the scouring-blades shall be caused to act upon the grain under pressure without the use of a vertical column of grain to secure such pressure. Claim: A scouring-cylinder arranged to receive or discharge the grain at either end thereof according to the direction of rotation of the scouring-blades therein, a vibrating screen and a chute, such vibrating screen arranged to deliver the grain therefrom into one end of such scouring-cylinder, such chute arranged to deliver the grain supplied thereto to the other end of such scouring-cylinder, and a valve arranged when in its operative position to direct the grain from such vibrating screen into such chute.

Manufactured by C. H. Bidwell Thresher Co. - Batavia, Genesee County NY

Abstract: The object of my invention is to provide an improved means for the removal from the machine of the fine particles of dirt and small seeds that escape through the usual screen in the lower grain-pan of a threshing-machine, such that such fine particles of dirt and small seeds shall he carried to one end of the machine and delivered there in a pile rather than having such fine particles of dirt and small seeds delivered to a barrel by the usual worm working in a trough. I have found that the use of a barrel for catching this refuse is objectionable, in that it takes up room and the barrels when full have to be removed and replaced by empty ones. Claim: In a threshing-machine, in combination with a grain-pan having a screen therein and a trough and worm beneath such screen, a fan supported at one end of such trough and worm therein, such worm arranged to deliver the contents of such trough to such fan, and means for revolving such fan and delivering the contents emptied therein from such worm to one end of the machine, such fan supported on a sleeve revoluble on the shaft for such worm, such sleeve also carrying a pulley by means of which such fan may be driven.

Assigned to Joseph Reif - Hebron IN

Claim 1: In a wrench, the combination of a pair of members, each provided with a gripping jaw, a handle rigid with one of the members, teeth on the members respectively inter-meshing to force the jaws together by movement of the handle-member relatively to the other member, a frame for holding the members in connected relation, and a pivotal connection between the frame and the handle-member, said connection comprising lugs formed on the sides of the handle-member and slots formed in the frame, said slots having open ends to permit lateral insertion or withdrawal of the lugs. Evolved from earlier patents 883,287 and 899,805. The REIF wrench brought to market more closely resembles this patent than the earlier ones.

]]> https://www.datamp.org/patents/displayPatent.php?id=45120&pn=671,579 Self-Feeding Mechanism for Threshing Machines Patentee: Charles H. Bidwell - Medina, Orleans County NY Granted:1901-04-09
Manufactured by C. H. Bidwell Thresher Co. - Batavia, Genesee County NY

Abstract: I have found that the feeding mechanism usually employed in grain-threshing machines does not work satisfactorily in bean-threshers on account of the tendency of the bean-stalks, especially after remaining any length of time in the mow, to string and pass over the feeding mechanism in bunches. Another objection to the feeding mechanisms used in grain-threshing machines consists in the difficulty experienced in attempting to remove stone from the beanstalks just before they enter the cylinder. The present methods of harvesting beans result in quite a quantity of stones being clogged up with the beans, and frequently they get upon the table and over the feeding mechanism into the cylinder, damaging the cylinder and concave. To overcome these difficulties, I have devised a self-feeding mechanism in which the presence of stones of any size sufficient to do serious damage gives an audible signal, and the operator may then readily tip the feeding mechanism in such a way that the stone will pass off from the feeding mechanism onto the ground without entering the cylinder. Claim: In a threshing-machine, a feeding mechanism consisting in a shaking- pan having teeth formed thereon, a handle or lever and connections between such handle and shaking-pan whereby such pan may be swung upward and to the rear on its operating crank-shaft by the movement of such handle, mechanism for operating such crank-shaft and connections between such handle and mechanism whereby the operative connection between such crankshaft and mechanism may 8 be broken by the movement of such handle.
