EMIL PRIETZ, OF OHRISTIANSTADT, PRUSSIA, GERMANY.
LATH E ATTACHM ENT.
SPECIFICATION forming part of Letters Patent No. 431,392, dated July 1, 1890..
Application filed July 18, 1889. Serial No. 317,953. (No model.)
.To all whom it may oon/cern.:
Be it known that I, EMIL PRIETZ, of Christianstadtonthe-]3ober, in the Kingdom of Prussia and German Empire, have invented new and useful Improved Means and Apparatus for Shaping Vood, Metal, and the Like,
of which the following is a specification, reference being had therein to the accompany ing drawings.
My invention consists in combining with the cutter-spindle having a driving-wheel at its end a supplemental driving means, also connected with said spindle for driving it at a different rate of speed.
In the drawings, Figure l is a plan view of the mechanism attached to a lathe; Fig. 2, a side elevation of the same; Fig. 3, a front View of part of the same; Fig. 4., a detail sectional view on line @c of Fig. 2.
In the drawings, the cutter X is held upon the main spindle fn, by nuts 0^ v". This spindle has bearings inthe ends mx of the main supporting-frame Z2, one end being engaged by the needle-pointed screw p, extending through the bearings w. The main frame h consists of the two arms b,which have the bearings a," ce thereon, said arms extending rearwardly and toward. each other to unite with the main part b of the frame. A third bearing b5 is provided for the spindle n, this also being attached to the frame b by the yoke b4, extending from the front end of the main part ZJ of said frame. The spindle has an ordinary driving-wheel o, through which motion may be communicated to it. The supplemental driving mcans consists of the bevelpinions z on the spindle n, meshing with the pinion z, which is on the supplemental spindle or shaft y, extending at right angles to the cutter-spindle andsupported by the main part of the frame. ward end of the frame is formed so that the piniona'can be con venientlypositioned within it. The properposition of the spindle can be determined by the adjustable collar q, which bears upon the bearing b5 by the screw p, while the beveled pinion z can be adjusted by the adjustable collar b. Motion is coinmunieated to the spindle y by a pinion c at its rear end, which pinion is driven by the pinion d on a spindle y', which in turn is The yoke h4 at the for-` driven by a crank t. The spindle. y of the drivingpinion (l is supported in a bracket t'. This bracket has a collar w, which fits on the outside of the rear part of the frame l). This collar has a lug or lugs Z projecting there from, adapted to be alongside of the lugs m on the frame l), the attachment being con1- pleted by a screw Z.
A bolt or projection d is fixed upon the frame 1),.and by this the entire mechanism can be attached to the carrier of a lathe by the clamp-plate c, as shown. This allows the apparatus to be placed in any position. Another bolt 7L is provided, Fig. 3, in the slotted guide g, fixed by screws to the support ZJ, and this insures secure attachment to the support of a lathe.
I claim as my invention l. In combination, the spindle, the cutter .fr thereon, the wheel 0, attached to the spindle for driving the same, the shaft y at right angles to the spindle, the beveled pinions zz on the spindle and shaft, respectively, means for driving the shaft y, and the supportingframe h, substantially as described.
2. In combination, the spindle, the cutter :r thereon, the shaft g/ at right angles to the spindle, the pinions z z, the supporting-frame I), and means for driving the said shaft y, consisting of the gear d, with the crank t, suptially as described.
4.-. In combination, the spindle with the cutter the means for driving said spindle, the frame having bearings ai ai and means for adjusting the said spindle in its bearings, and the pin d., for securing said parts to the lathe, substantially as described.
In witness whereof Ihave hereunto set my hand in presence of two witnesses.
EMIL PRIETZ.
