@uiten isrs @anni @Hirn LAFIYETT BARNUM, oF BRIDGE-PennCONNECTICUT, issuance4 To' HIM; SELF, LEVI BARNUM, AND CHARLES u. ENSIGN, or 4SAME PLAGE.,
Letters Patent No. 79,627, dated July/ 7, 1.868.l
IMPROVED MACHINE FOR CUTTING AND DRESSING STONE.
TO ALL WHOM IT MAY CONCERN:
Be it known th'at I, LpFAYETT BARNUM, of the city of Bridgeport, iu the `county of Fairfield, and State of Connecticut, have invented a new and useful Improvement in Machinery for Cutting or Dressing Stone;l and I dohereby declare that the followiug`is a full, clear, and exact description of the construction, character, and
operation of the same, reference being had to the accompanying drawings, which make part of this specificav tion, in which- I -Figure 1 is a perspective view of the whole machine, showing-one of the main cam-shafts, most of the train of gear-wheels, andof the feed-motion.
Figure 2 is a section of the same, cut longitudinally and vertically through the central part of the machine,
showing the cross-section of all of the cam-shafts, and some of the cams, hammers, cutters, springs, doc.
Figure 3 is a perspective View of a double-edgedcutter fitted toiinish one of the longitudinal corners of the stone at any desired angle.
My improvement consists in constructing the machine withtwo or more shapes oT cutters, as pointed for rough'cutting on dat surfaces, wedge-shaped for smoothing, serrated surfaces for finishing, double-edged (asig.
3) foredging, &c., aud inthe manner of feeding the stone (tohe dressed) on a double carriage, all substantially as hereinafter described.
I make the bed-plate or platform, A' A,with suitable legs, as B B, of cast iron' or any other suitahle material, of sufficient size and strength for the work intended to he donc. l
On the upper surface of this platform A A, I tit two ways or Arails, as 'represented at a and a', iig 1, on whichthe sliding hed L moves, to feed the stone to the cutters, by means ofthe feed-motion. l
Near each corner ofthe platform A A, I t or erect a. standard 'or post, three of `which'are shown at C,"C',
and D, iig. I, and two ef them are indicated at C'and D'in g.-2; and centrally, in each side, I erect another y standard or post, as shown at E and E', iig. 1, and one of them is shownat E', tig. 2. These six standards or posts, by means of tongues and groovcs,-`nold thc two adjustable frames,1i' and G, which contain all of the cams, hammers, cutters, Sie. A
Y In and under the platform A A, I t two spur-wheels, one as shown at I-I, fig. 1, and the other at I, iig. 2, both heing on the same shaft or-arhor, as shown'at b, figs. 1 and 2, which, by means of the hand or dog c, worked by thejointed lever d of, (the fulcrum of which is at c, and the crank-pin which operates it is atf,) as represented in iig. 1, and the rack g en the bottom of the sliding carriage 7L, 'ser e to feed the stone longitudinally in either direction, ns is desired, hy using the proper paul, that is, either z' orj, as needed.
I make the adjustable frame G and G' of four upright parts, as shown at K, K', L, and L', in iig. 1, and e two cross-liars, G and G', as shown in iig. 1, and as indicated in section at K', L', andG', iu iig. 2; and I secure the sides together hyvhars or rods, as shown at M, M', N, land N'.
To the bars or rods M and N,`I attachvsprin'gs, as and Z, to force down the hammers, as O and 0', upon the stocks, asp, of the cutters, as g, and to the hars or rods M' and N', I attach springs, as r ands, which support the cutter-stocks, as j), und cutters, as. qi
In the un er endof the u ri'rhls L and L', I fit a shaft or arbor as shown at I), a. 1, and indicated at P,
1P P c 2 o iig. 2, to which the main or driving-power is to hc applied by means of a belt on the wheel or pulley Q; and on the other end of the'shaft P, I place a small gear-wheel, as R, which, when putin motion, works the whole train' that puts in motion the cam-shafts, to work the hmuicrs, &c.; and the crank-pin in the plain wheel S operates the feeding-apparatus.
Iiit into this frame G G' two cam-shafts, one of which is plainly shown at R', fig. 1, and both indicated at R' and U in iig. 2. On the shaft R' twoeams, 'l and T', are shown as having released the hammers O and .0', and allowed them to fall on the cutter-stocks, :is p, to strike down the cutter-points, as g," andi-on these camshaftsI-iit loosely the ends of the hammer-handles, two of whichare shown at m and m', fig. 1, and one at m", iig. 2.
The otherl cam-shafa'in the frame G', which is indicated-in section in iig. 2, at U, (and has its position indicated by the large gear-wheel Y, 1, which is on that shaft, and one of the cams is partially shown at 1V, and indicatedby dots at U', fig. 2,)`is, with its ming-hammers, and springs, substantially the same as the one described, and is in-all respects,'but a part of' the same series of means for the rough cutting of the flat surface of the stone, although the .cutters may in'one case be pointed, and in another be Wedge-shaped.
I make the adjustable frame F and F', in all essential particulars', the lsanne as G and G', before described, exceptv that the shaft or arbor P is common to both, becausethe wheel R is connected rgith both trains of wheels through the large wheel V, Sac: But in the frame Fand F21 fit cutters for finishing, either with the Workingsurface ofthe wedge-shape, or thesquare'form, with its under surface doubly serrated or notched, for the nest finish, as shownin iig. 2, att, or otherwise. I l
.I use any desired number of cutters in cachot' these-frames; and I have the frames so adjustable vertically, (by means of thetongues and grooves in the uprights,) that they will conform themselves to the thickness ofthe stone; or the adjustment may .be limited by any proper gauge or gauges, s'o as-to cut the stone to any desiredthickness. The adjustability of the two fra-mes is wholly independent of each other.
I also use cutters for dressing the edges of the stone, of the same general character as those for tbeat surface, and use revolving hammers for working them, as is=indicated in g. 1, Where #represents one of the cutters, u the cutter-stock, and w one of the hammers, which revolve horizontally on a. vertical shaft or arbor,
asrepresentcd at y, While the cutter-stock u'is represented as being sustained by the curved spring z.
l Any desired number of these cuttersvfor dressing the edges maybe used, but I would recommend using no more than tnorevolving'hammers'on oneshaft, which shaft may be revolved by a'belt', as t, from the wheel Q on t'o` the vertical Wheel k', to revolve the horizontal `wheel indicated at l', which is on the vertical shaft y, all of which is represented iu 2, and mostly in iig. 1, And when deemedbest, the edging-cutter may be made in the double form,'as represented in lig. 3, where'the edge awilldress the edge of the stone, while the cuttingedge b.will smooth and finish the upper surface, so as to form a'perfect cornerof any desired angle. And the' feeding-apparatus may be varied to suit any desired curve-line of edge, by fitting a superincumbent table, as represented atvc., figs. land 2, which' may partiallyrevolve on the centre d', While guided or steadied by the duplicate curved projections indicated ate andf, fig. 2, which may be continued toa-perfect circle, which will enable me to give any desired curve or Waving lto the edge, as for a mantel-inerte,r table, &c.
What I claim as my invention, and desireto secure by Letters Patent, 'isll Y 1. -The combination of lthe adjustable frames with the cams,hammers, cutters, and feeding-apparatus, when the Whole is constructed, arranged, and fitted to operate'substantially as herein described and set forth.
2. The apparatus for feeding the stonelongitudinally', with the method of swinging it on its centre, solas to form a curvilinear edge, and thev edge-cutters, when constructed, arranged, and fitted to operate substantially as herein Adescribed and set forth# 3. The combination of the double-edged cutters (fig. 3) with the rotary hammers, when 4they are constructed and used substantially as and-for the purpose herein described and set forth.
LAFAYETT BARNUM.
