Die and Tool for Upsetting Tubes
|
John R. Blakeslee |
Cleveland, Cuyahoga County, OH |
Claim:
Heretofore in upsetting boiler-tubes and analogous articles in dies two difficulties have presented themselves: First, the male die becomes so tightly wedged in the article to be upset as to withdraw the article with the male die as the latter is withdrawn, and, second, it has been found almost impossible to avoid crimping, wrinkling, corrugating, or or what is known as "cold-shutting" on the part of the upset portion of the tube. |

Planing Machine
|
John R. Blakeslee Jr. |
Glenville, Cuyahoga County, OH |
J. B. Fay, patent attorney. Inventor John R. Blakeslee was deceased; John R. Blakeslee, Jr., was administrator. My invention relates to planing machines, and particularly to planing machines for operating upon large and cumbersome work. The object of the invention consists in providing a planer structure whereby the planing operation may be performed upon such large work in a manner more economical than has heretofore been practiced. I therefore particularly point out and distinctly claim as my invention: 1. In a planer, the combination of a frame constructed of four standards; and two longitudinal, parallel members supported thereby and formed with guide-ways on their upper faces, the space intermediate between said standards being open for the reception of work; an arched yoke secured to said standards at one end of such space; driving mechanism supported within said yoke; a bed-plate being fixed with respect to said frame and forming the lower limits of such space, an extended substantially flat, horizontally disposed reciprocatory head provided with a centrally arranged longitudinally extending rack and having its opposite ends resting on the guide-ways provided by said frame; a tool holder mounted on one end of said head and transversely reciprocable across the same; and means substantially as described adapted to reciprocate said head and tool holder, respectively. 2. In a planer, the combination of a frame including four standards, and two longitudinal, parallel members supported thereby and formed with guide-ways on their upper faces, the space between said standards being open for the reception of work; an arched yoke connecting the standards at one end of such space; a bed-plate for holding the work, said bed-plate being fixed with respect to said frame and forming the lower limits of such space; a reciprocating tool holding head having its opposite ends slidably resting on the guide-ways provided by said frame; a tool holder mounted on one end of said head and transversely movable across the same; a centrally arranged longitudinally extending rack borne by said head; and driving mechanism supported within said arched yoke including a gear in mesh with said rack, and means adapted to move said tool holder as stated. |

|
Leo D. Mersek |
Richmond Heights, Cuyahoga County, OH |
Claim:
The present invention relates to wire straightening units of the type comprising a series of rollers carried on a frame so as to engage opposite sides of a wire passing therebetween and flex and straighten the wire and to remove any tendency of the wire to kink. |

Wire Working Apparatus
|
Ben F. Ware |
Euclid, Cuyahoga County, OH |
Abstract:
Apparatus for performing work operations on relatively small diameter wire intermittently advanced therethrough including a frame supporting first and second slides spaced along the wire in the direction of its feed, rotatable wire working rolls carried by one slide, and a wire drawing die carried by the other slide, means for reciprocally moving the slides relative to the frame to effect working on the wire by the rolls and die in gone direction of movement, and separate wire feeding means in advance of each slide. |

Stock Transfer Mechanism
|
Albert R. Kull |
Beachwood, Cuyahoga County, OH |
Abstract:
A stock transfer mechanism for forging machines including opposed vertically movable slides each mounted on opposed horizontally movable slides, each horizontally movable slide being driven by a piston-cylinder assembly through a pressure differential device, the transfer mechanism including turn-grip segments journaled for rotation substantially about the center of the stock with pawl means being operative to rotate the segments as the supporting slide moves up and down. |

Roll Forging Machine and Method
|
Mike B Martincic |
Mentor, Lake County, OH |
Abstract:
A roll forging machine includes an automatic stock feed which receives the stock in a receptacle from a conveyor and then swings the stock to a horizontal feed position after sensing the temperature of the stock. If the stock temperature is insufficient for proper forging the receptacle swings to a dump position to return the stock to a furnace. If the stock temperature is sufficient the receptacle in the horizontal position is indexed into the forging rolls and to place the stock into a stock gripper of a transfer. The stock gripper is mounted on a grip slide for movement in the "X" direction aligned with the direction of the roll passes. The grip slide is in turn mounted on a carriage for movement in the "Y" direction transverse the direction of the roll passes. Both the grip slide and the carriage are driven electrically by respective servomotors in turn driving timing belts to which the carriage and grip slide are clamped. The servomotor for the grip slide accelerates the stock to a predetermined velocity until the stock is engaged by the forging rolls and then enters a free-wheeling mode during roll forging during which the grip slide is driven by the forging rolls, and then decelerates the stock. During the free-wheeling mode the servomotor for the grip slide may exert a slight tension or compression bias on the stock. The carriage moves the grip slide from pass to pass and may do so in any order. During the movement from pass to pass the gripper and thus the stock is rotated 90 degree. At the completion of the roll forging the grip slide accelerates the stock to an exit velocity whereupon the stock is released by the gripper to exit the machine. The grip slide returns the open gripper to receive the next stock to repeat the roll forging cycle. |
