To all whom it may concern.-
Be it known that I, GEORGE E. GREEN LEAF, a citizen of the United States, residing at Plainfield, Union county, New Jersey, have invented bertain new and useful Im rovements in Formers for Lathes, of which. the following is a specification.
This invention pertains to improvements in fornlers for la'thes designed to guide the turning tool in a path departing from parallelism-with the axis of the lathe for the purpose of producing longitudinally curved contours on the work produced.
The invention will be readily understood from thefollqwing description taken in conneat-ion with the accompanying drawing in which:-
Figure 1' is a -pla'n of a former exemplifying my invention: Fig.2 is aside elevation of the same: and Fig. 3 a rear elevation of the rear pivot-carrier.
'Inthe. drawing:l, indicates the lathe bed: .2, the carriage. 3,'the tool-holder: 4, the tool all "of the parts thus far referred to ha v ing no peculiarities: 5, a guideway crosswise of the lathe and disposed at the rear of the bed and fixed to the bed at any desired point along .the length of the bed: 6, a rear pivot-carrier mounted to slide freely on guideway 5: 7, a vertical pivot carried by pivot-carrier 6: 8, a vertical pivot carried by the tool'holder: 9, a link oonneoting the two pivots: 10, a former-plate rigidly secured to the carriage: 11, a longi tudinal slot in the former-plate, the slot being illustrated as having a straight portion and a curved portion: and 12,21 roller projecting from pivot-carrier 6 down into the slot of the formerplate.
Assume the carriage to be feeding in the direction of the arrow of Fig. 1. Pivot 7 partake/s of=no motion but roller 12 is traversed by the straight portionof the slot in the formerfplate. The result. is that pivot 7 is maintained at a fixed distance from the vertical'plane of the axis of thelathe and, as link 9 swings on pivot 7, the tool-holder is drawn toward the vertical plane of the- Specification of Letters Patent.

lathe-axis, and the point of the toolwill vertical plane of the lathe-axis and the curvature ofthe longitudinal contour produced upon the work by the point of the tool will be of less radius than that due to the mere length of the link, whileif the curve of the slot were in the opposite direction the curvature of the contour produced by the tool would have a radius. greater than that represented by the length of the link.
The former-plate is removably secured to the carriage and itfollows that the slot in the former-plate may be given such form as to produce any desired curved cont-our on the work being turned, and that, by employing selective. former-plates,various contours of work may be provided for, and it will at once he recognized that the .device is ex-.:
tremely simple and substantial.
I claim.
1. A former for a lathe comprising, a guideway dispo==eo transversely of the lathe bed and secured to the lathe-bed, a pivot carrier fitted to slide in said guideway, a pivot carried by the pivot-carrier, a pivot carried by the tool-holder'of the lathe, a
But when the roller reaches the link connecting the twopivots, a formerplate secured to the'carriage' and having longitudinal guiding surfaces, and a connection between the pivot-carrier and the guiding surfaces of the formenplate, combined substantially as set forth.
2. A former for a lathe comprising, a
guideway disposedtransversely of the lathe bed and secured to the lathe-bed, a pivotcarrier fitted to slide in said guideway, a gaging said slot, combined substantially as pivot carried by the pivot-carrier, a PIVOt carried by the tool-holder of the lathe, a
link connecting the two pivots, a formerplate carried by the lathe-carriage and provided with a longitudinal sl0t,;an'd a projection carried by the pivot-carrier and. e11
set forth.
