IMPROVEMENT IN GUIDES FOR PLANING-MACHIN'ES.

The Schedule referred to in ihese Letters Patent and making part of the same To all whom it may concern Beit known that I, FRANKLIN KEAGEY, of Chambersburg, in the county ot' Franklin, andY State of Pennsylvania, have invented a new and improved Machine for Cutting Irregular Forms; and Ido hereby declare that the following is a full, clear, and exact description thereof', which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to improvements in machines for holding, adjusting, and feeding the pillars, balusters, or other articles to be dressed in irregular forms or plain sides, on a table, past a rotary cutter, by which the dressing is to be elfectved, thesaid invention consisting of a bed, with centres, for holding the blank, one ot which is adjust-able as to length, and provided with a dividing-plate, for adjusting the Blank to the cutter;` also a pattern, for governing the act-ion' of the tool on the blank. t

Figure 1 represents a longitudinal section ot' my improved machine;

Figure 2 represents a plan view of the same;

Figure 3 represents a view of one of the patterns; and

Figure 4 is a transverse section, taken on the line a: :z: ol' iig. 2.

Similar letters of reference indicate corresponding arts. D A is the bed whereon are placed two spindle or centring-heads, B and C, the former having either a.' spindle, for holding the blank I), or for special, Work it may' have a hole for the turned end of the blank.

The latter is provided with an adjustable spindle, D', and is adjustable along the bed, in the manner of lathe-heads, for blanks of different lengths.

The spindle D isprovided with a templet or dividing-plate, E, with spacing-notches, and detachably connected, vso as to permit ot intel-changing plates, with various arrangements of notches, in which a spring-catch, F, works, to hold itat any point.

G is a guide or pattern, adj ustably connected to the bed.

H represents a rotary cutting-tool, rising up through the table I, shown in dotted lines, on which the bed' A is placed, `so as to press the edges of the pattern up against the mandrel of the cutter, below the same, wherebythe depth of cutting is gauged, as the inachine is moved along past the cutter by hand. ,n

The pattern is swivelled out at the pla-ces where it is required, to prevent the cutter from acting on the blank, as at K L M.

'lhe said patterns may be of any required form for the work required, dilerent patterns being required for different work.

N is a hand-rail, placed on the bed A, to facilitate moving the same around on the table I, in moving the blank up against the work. t

The blanks, after being turned in some parts inthe ordinary turning-lathe, are pla-ced in this holding-device, for dressing the sides either in plain or irregular forms, as will be clearly understood by inspection of the drawings.

Having thus described rrnyinvention,

I` claim as new,` and desire to secure by Letters Patent- The arrangement of the pattern-guide G on the bed A, and, with respect to the centres, in the mauner described and for the purpose set forth.

FRANKLIN KEAGEY.
