Description
f G i vi@ l 9 tegoed 5mm @met @time "rf W "Wwe/ JOHN T. CAMPBELL, OF ALTOONA, PENNSYLVANIA. Laim Patent No. 84,410, dated November 24, 186s.
IMPROVEMENT IN 'NUT-PLANERS The Schedule referred to in these Letters Patent and making part of the same.
To all whom it ma/y conce/m:
Beit known that I, J ons T. CAMPBELL, of Altoona, State of Pennsylvania, have invented-a Nut-Facing and Turning-Machine; and I do hereby declare the following to be afull, c lear, and exact description of the same.
My invention consists of certain mechanism, fully described hereafter, by which a number of nuts can be simultaneously faced and bevelled.
In order to enable others familiar with machinery of this class to make and use my invention, I will now proceed to describe its construction and operation, reference being had to the accompanying drawing, which forms a part of this specification, and in which- Figure l. is a vertical section of my nut-facing and turning-machine.
Figure 2, a transverse vertical section,
Figure 3, a plan view, and
Figure 4,' a detached view of part of the machine.
Similar letters refer to similar parts throughout the several views.
A and A are the two end frames of the-machine, and are connected together by a bed-plate, B, on the upper face of which are two longitudinal dovetailed ribs, a a, adapted to similarly-shaped grooves in the slide B, to which is fitted a transverse slide, E, after the plan adopted in constructing ordinary slide-rests for lathes, the last-named slide having a rack, b, into which gears a pinion, d, on a spindle, e, turningin bearings on the slide.
The slide D may be operated by hand, or by any appropriate appliances.
On each end of the bed-plate is a standard, F, andin one standard turns ythe small end of the spindle G, the large. end of the latter having a; central recess for receiving the pointed end of'a set-screw, f, in the other standard.
In the present instance the spindle is arranged for the reception of four nuts, 1, 2, 3, 4, of different sizes, each nut being screwed into the spindle, and against a shuulder on the same, as seen in iig. l.
To the slide E are screwed four tools, m, m', m, and
m, on one side` of the spindle, and a single tool, n, on
the opposite yside of the same, the arrangement of these -tools being best observed on .reference to lig. 3.
Each of the tools mmm"m has two cutting-edges, one straight and the other bevelled, so that on moving arrows, lig. 3, while the spindle and its nuts are revolving inA a contrary direction, the inclined cutting- .edge of the tool m will bevel the top of the smallest nut, while the straight cutting-edge will face the base of the adjacentnut next in size, and so on throughout the series of nuts.
A fifthtool, not shown in the drawing, may be used for facing the base of the smallest nut.
After this simultaneous facing and bevelling of the whole of the nuts, the latter must havea fiat surface formed on their tops. This is accomplished bythe tool n, which, by aproper manipulation of the slides, can be brought to bear upon each nut in succession, so as to form the desired dat surface on the tops of the nuts, round the edges of the holes in the same.
It would be needless to describe minutely the advantages of the above-described machine, as they will. be apparent to all who. are familiar with machine-shops, in which large quantities of nuts are used, and in which their rapid completion, ready for use, is an important desideratum.
It will be understood that a number of nuts `of the same size may be operated ou simultaneously, and that.
the nuts, instead of being screwed on to the spindle, may be iitted loosely to the same, with appropriate' distance-pieces between them, the series of nuts being confined between a shoulder, near one end of the spindie, and a nutonfthe other.
I claim as my invention, and desire to secure by Letters Patentl. The combina-tion of one or more tools, m m', and a revolving mandrel, G, all constructed, arranged, and operating together, substantially as and for the purpose set forth. o 2. The combination and arrangement of the revolving mandrel G, sliding tool-rest E, edge-planing tool n, and the double-edged tools 'm m, all constructed and voperating substantially in the manner described.
In testimony whereof, I have signed myname to this specification, in the presence of two subscribingwitnesses.
JOHN T. CAMPBELL. Witnesses:
JAMEs DUNN, JOHN SHOEMAKER.
