| 161 | Apparatus for continuous pressing of bolts, screw blanks or similar parts | US702862 | 1976-07-06 | US4052873A | 1977-10-11 | Horst Murzin; Gunter Grygo |
| Apparatus for shearing blanks from elongated workpieces and for pressing such blanks into screw blanks, bolts or the like in a continuous operation comprises a plurality of preferably cylindrical rotary elements, rotatable about parallel axes in such a manner that cooperating pairs of rotatable elements are rotated in opposite direction and so that blank receiving members on the rotary elements of each cooperating pair becomes successively aligned with each other. The plurality of rotary elements includes a central rotary element receiving sheared-off blanks and retaining the same during the pressing thereof until the final discharge, and a plurality of additional rotary elements arranged about the circumference of the central rotary element. One of the additional rotary elements serves to shear off blanks from the elongated workpieces and to transfer such blanks to the central rotary element and at least two further rotary elements cooperate with the central rotary element for forming the blanks through pressing. | ||||||
| 162 | Method of making lap pin | US43687274 | 1974-01-28 | US3868842A | 1975-03-04 | ANTHONY WILLIAM EDWARD |
| A method for forming a lap pin is disclosed, the lap pin being used with a cotton picker in one of the first stages of the processing of cotton from its baled condition into yarn. A lap pin is employed in the machine in order to roll up the first portion of the processed cotton into a lap. The lap pin is a single piece of forged steel having its end turned down to final dimensions for positioning within the picker. The sharp corners at the two ends are provided to accurately size the unit but the unit itself is completely of one piece construction to eliminate breakage at joints or securing points of a multi-piece lap pin, and the material is selected of high carbon steel to provide a spring action to accommodate foreign material which is always found present in the cotton as it passes through the picker. The method consists of a two-step forging which results in uniform molecular flow around the joint between the ends and the body portion. In addition, heat treating in a carburizing atmosphere at a temperature of not less than 1,450*F. for not less than four hours is set forth.

| A method of die-forming parts so that, in their final shape, they have a substantially continuous grain structure, whereby a cylindrical blank is shaped into a spherical part by drawing the grain line ends together in two polar areas, and the spherical part is reshaped into a ring of final dimensions without breaking any of the grain lines.

| 164 | Apparatus and process for making hollow ball bearings | US3731359D | 1972-02-24 | US3731359A | 1973-05-08 | GLENN E |
| The apparatus and process for making hollow ball bearings which comprises means to stamp round metal blanks from flat metal stock, stamping round metal blanks, forming means to form the blanks, drawing and forging the blanks to establish pairs of concavo-convex hemispheres, spaced relatively shiftable welding electrodes with hemisphere receiving welding seat, arranging the pairs of hemispheres between two electrode welding seats with their concaved surfaces in opposed relationship, urging the rim portions of the opposed hemispheres into pressure engagement with each other and welding them together to form hollow ball bearings.

| A double stroke - double blow header in which a slide is mounted in a machine frame for linear reciprocal movement, a punch attached to said slide, and a forming die fixedly secured to said machine frame in axial alignment with and in opposition to said punch and having a product ejecting knockout pin therein, a stationary cutter fixedly secured to said machine frame in parallel to and spaced from one side of said forming die and having an opening through which wire material is to be fed, a movable cutter having an opening for receiving a portion of said material and also for loosely receiving a pin therein and reciprocally movable between said stationary cutter and said forming die, a drive shaft rotatably supported in said frame and having an integral eccentric sheave thereon, a rockable slide drive lever fitted on said eccentric sheave and having one end connected to said slide through a linkage for driving the slide, a follower shaft rotatably supported in said frame to be driven by said drive shaft with a rotational speed ratio of 2:1 with respect to the drive shaft and having two integral eccentric sheaves thereon, a control level fitted on one of said eccentric sheaves on the follow shaft and pivotally connected to the other end of said slide drive lever, and an operation bar fitted on the other eccentric sheave on said follower shaft for actuating said knockout pin to eject a formed project out of said forming die.

| 166 | Hollow bearing ball and process for making them | US3660880D | 1970-03-27 | US3660880A | 1972-05-09 | GLENN EDWARD R |
| A hollow bearing ball formed from a relatively resilient steel by initially stamping a round blank from a strip, drawing the blank, and forging and flowing the drawn blank of metal to subsequently form a substantially hemispherical portion of a hollow bearing ball. The hemispherical portions are fed into a hopper which serve to place them in opposed concave relationship after which they are interposed within and between two electrode welding seats which hold the hemispherical portions under pressure and weld them to form a hollow bearing ball.
