1,244,084	Oct. 23, 1917	Tapping Machine	Arthur A. Shafer	Erie, Erie County, PA	Claim: The combination in a machine of the class described, of a frame, a vertically movable sleeve mounted in the lower portion of said frame, a series of rack teeth on said sleeve, a sleeve slidably and rotatably mounted in the upper portion of said frame, a tool spindle passing through said sleeves, means to cause said spindle to rotate with said upper sleeve while permitting longitudinal movement of the spindle in the sleeve, collars secured on said spindle above and below said lower sleeve to prevent said sleeve sliding on said spindle, a friction disk around said upper sleeve, a sleeve non-slidably journaled on said upper sleeve, arms on said sleeve, a shaft journaled in said arms, a spur gear on said shaft intermeshing with the rack teeth on said lower sleeve and means to cause said shaft and spur gear to rotate.
1,345,709	Jul. 06, 1920	Threading Die Mechanism	Arthur A. Shafer	Erie, Erie County, PA	Claim: In a device of the character described, a die-holder, dies mounted therein, a rotatable cam sleeve on said die-holder for actuating said dies, an inclined plate secured thereon, a longitudinally-movable ring engaging said inclined plate to rotate paid said ring, and means to prevent the rotation of said ring on the die-holder.
1,345,744	Jul. 06, 1920	Collapsible Tap	Rudolph A. Boehm	Erie, Erie County, PA	Claim: A collapsible tap comprising a body mhember having radial slots in one end thereof and a cylindrical chamber in the opposite end thereof, chasers slidably secured in said slots, longitudinally movable means with said body member engaging the inner ends of said chasers adapted to shift the same, the diameter of said chasers being greater than the diameter of said body inem-her, rotating means mounted on said longitudinally movable means adapted to impart longitudinal movement thereto, at shank, a hub thereon slidably mounted within the cylindrical chamber in said body member. means to prevent rotary movement of said hub within said body member, and means to yieldingly press said hub inwardly in said body member.
1,345,710	Jul. 06, 1920	Collapsible Tap	Arthur A. Shafer	Erie, Erie County, PA	Claim: In a collapsible tap a body member having radial slots, chasers slidably mounted in said slots, a central shaft member in said body, cam surfaces carried thereby adapted to force said chasers outwardly at one movement, and the cam ring mounted thereon and rotatable with said central shaft to force said chasers inwardly at the reverse movement thereof.
1,415,013	May. 09, 1922	Collapsible Tap	Rudolph A. Boehm	Erie, Erie County, PA	Claim: In a collapsible tap, a body member, radial chasers slidably mounted in one end thereof, a slrank rotatably and slidably mounted in the opposite end of said body member, a longitudinally movable central member within said body and shank members adapted to control the radial movement of said chasers, cam mechanism actuated by relative rotative movement of said body and shank members to control the longitudinal movement of said central member, and interlocking means between said body and shank members adapted to prevent relative rotation and be disengaged by relative longitudinal movement.
1,470,683	Oct. 16, 1923	Screw Cutting Machine	Rudolph A. Boehm	Erie, Erie County, PA	Claim: The object of my invention is to provide suitable mechanism adapted to be placed upon a lathe, which will cut threads upon a rod at a plurality of points in the length thereof simultaneously.
1,560,487	Nov. 03, 1925	Automatic Screw Threading Machine	Arthur A. Shafer	Erie, Erie County, PA	Claim: In a machine of the class described, a hollow sleeve shaft, means to cause the same to rotate, worm threads on said sleeve shaft, a hollow shaft within said sleeve shaft, adapted to receive the shank of a threading die holder in one end thereof, key and keyway mechanism adapted to permit the hollow shaft to move longitudinally within said sleeve shaft while being revolved thereby, gear mechanism adapted to be actuated by said worm threads to cause said hollow shaft to reciprocate, and means to present a succession of work pieces to said threading die.
1,560,462	Nov. 03, 1925	Self Opening and Closing Threading Die Holder	Rudolph A. Boehm	Erie, Erie County, PA	Claim: In a device of the class described, a shank head having a radially slidable chaser mounted therein, a rotatable shaft mounted in said head, adapted to be rotated to engage said chaser to retain it in said head, a spring pressed ring longitudinally slidable on said head, coacting means in said ring and on said rotatable shaft adapted to rotate said shaft, spring pressed latch mechanism mounted in said ring, and stop mechanism adapted to be engaged by said latch mechanism to limit the longitudinal movement of said ring on said head.
1,936,274	Nov. 21, 1933	Die	George E. Shafer	Erie, Erie County, PA	Abstract: This invention is directed to that type of die which ordinarily automatically opens, or releases the chasers at a pre-determined point in the operation. Such dies commonly have a set position and with the present structure an improved form of lock is provided for locking the die in its set position. In connection with this improved look there is also provided a second latch which positions the die in released position. The latches and locks are so arranged as to permit of a third position of the locking means so as to permit. of the parts assuming a position permit-ting the removal of the chasers. The invention also contemplates the improvement of the cam means controlling the chasers and of the setting, or adjusting means for adjusting the cams operating on the chasers. Claim: In a die, the combination of a head: chasers in the head; a cam ring acting on the chasers; a catch locking the cam ring in set position comprising a floating split ring; a shoulder carried with the head against which the split ring seats; an actuator opening the ring to release the 'die; a second catch stopping the cam ring at released position; and a second shoulder engaged by the split ring when the second catch is released, the cam ring with the split ring in the last-mentioned position permitting the removal of the chasers
1,978,060	Oct. 23, 1934	Work Feeding Device	Arthur A. Rickert	Erie, Erie County, PA	Claim: In a machine of the character described, the combination of a spindle; a collet in the spindle; a collet actuating member; a reciprocating air actuating means operating the member in which the spindle is journaled; an air housing distributing air to the opposite sides of the means; an air valve controlling the air delivered to the means; and means circulating cooling fluid in cooling relation with the housing.
1,978,059	Oct. 23, 1934	Cutting Off Machine	Arthur A. Rickert	Erie, Erie County, PA	Claim: In a machine of the character described, the combination of a spindle adapted to rotate the work; tool posts, one at each side of the spindle and each having a tool support; a pivotal mounting for the posts having an axis parallel to the axes of the spindle; arms extending from the posts to the opposite sides of the mounting from the tool supports and extending in substantially direct lines from the tool supports; and cams acting on the arms for actuating the posts.
