Description
WILLIAM NEWSHAM, 0F PHILADELPHIA, PENNSYLVANIA, ASSIGNOR T l MORRIS, TASKER, & UO., OF SAME PLACE.
Letters Patent No. 104,985, dated July 5, 1870.
IMPRCVBD MACHINE POR CUTTING DIES.
The Schedule referred to in these 'l'.ettexs Patent and making paxt of the lme I, WILLIAM N EWsHAM, of the city ofPhiladelphia and State of Pennsylvania, have invented a new and improved Mode of Cutting Dies Eccentrically, of which the following is a specification.
The nature of my invention consistsin giving cccentricity to the cutters by means of a vibratory movement imparted to a bed-plate on which the die is confined, the said movement being effected by means of a revolving eccentric shaft, while the tap is advanced through the die, as hereinaiter describedj y To enable others skilled in the art to which my iinprovement appertains to make and use my invention, I will now give a detailed descriptionthereofl In the accompanying drawing which makes a part of this specilication- Figure 1 is a front elevation of a machine having the improvements'.
Figure 2 is a vertical section through the line :c a: of g. 1. i
Figure 3 is a plan of the machine.
Figure 4 is a cross-section at the line y y of Iig. 1.
Figure 5 is an end view of the leccentric shaft K.
Figure 6 is a plan of the reciprocating bed-plate B and cross-section of the lower end of the tap H and shaft K.
Like letters in all the figures indicate the'same' parts.
A is the permanent part of the machine. A B is a reciprocating bed-plate which receives the hub a of the gear-wheel D, on which the die E to be gli; is secured by means of the clamp F and bolts The tap H is connected at its upper end in the socket b of the vertical shaft J, which is elevated and depressed by anysui-table mechanism.
The lower endlof the tap has a projection, d, wlnch lslides in the socket e, seen in fig.- 2.
. The pinion D on the'vertical shaft K gears linto the wheel Dabove described, and the said shaft, be.- ing rotated in any convenient manner, the wheel 1s rotated with the die E as the tap H .is advanced through the die.
The eccentricity is given to the die by means of the eccentricity of the shaft K within the eye f ot' the bed-plate Bas the shaft revolves. The eccentric formationis represented in figs. 4 and 5.
The hub of the pinion D is also concentric, as seen in fig. 2, so as to increase or decrease the vibration of the bed-plate B.
What I claim as my invention, and desireV to secure by Letters Patent, is-l The combination of the eccentric shaft K, reciprocating bed-plate B, gear-wheel D, and pinion D', the
several parts being constructed, arranged, and operating in relation to theftap H, substantially in the manner and for the' purpose above described.
In testimony that the above is my invention, I have hereunto set my hand und aixed my seal this 12th day of May, 1870.
