SPECIFICATION forming part of Letters Patent No. 298,132, dated May 6, 1884-. Application filed February 14, 1884. (No model.)
To aZZ. whom it may concern.-
Be it known that I, NELsoN J. SWAYZE, a citizen of the United States, residing at ttonwood Falls, in the county of Chase and State of Kansas, have invented certain new and useful Improvements in Stone-Dressing Machines; and I do declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, ,which form a part of this specification.
My invention has relation to stone-dressing machinery; and its object is to take the rough blocks and rapidly and expeditiously dress or plane them to given sizes;'and to that end the novelty consists in the construction, combination, and arrangement of the machine, as will be hereinafter more fully described, and particularly pointed out in the claims.
In the accompanying drawings the same letters of reference indicate the same parts of the invention.
Figure 1 is a perspective view of my improved stone-dressing machine, showing the relative position of parts. Fig. 2 is a horizontal section of the main operating-shaft be- Fig. 3 is a plan view of the main driving-shaft, with belt to the operating-shaft, and showing the belttightener in position; and Fig. 4 is a section on the line a" w of Fig. 3, showing the said Fig. 5 is an elevation of the main operating-shaft and its connected mechanism. Fig. 6 is a section of one of the forward chisel-arms with the roughing-chisels in place. Fig. 7 is a similar view of the finishing or bush-hammer chisels, and
Fig. 8 is a section of one of the carriagestandards. I
2 and 3 are heavy timbers, suitably erected to form a frame corresponding to the size of the machine.
4 is the main operating-shaft, and it is mounted in suitable bearing-boxes, 5 and 6, secured to timbers. (Not shown, but which are rigidly attached to the frame 2 and 3.)
The shaft 4 is provided with a pulley, 7,
which drives it by a belt (not shown) from the engine.
is avoided. Each eccentric l0.is provided with a strap, 11, the lower half, 12, of which is cast integral with the cutter-arm l2, and the end of the arm 12 has two socket-holes, 13, which receive the taper ends of the cutter-bits 14, which have transverse holes 15, through which are inserted the ends of the stud 16, rigidly secured to the lower end of the pitman 17 and theupp'er end of this pitman is pivoted in the socket 18 on the regulatingscrew 19, adj ustably secured tot-he girder 20 by nuts 21 22. The object of this arrangement is to regulate the depth of the cut to be taken by the bits 14, for it will readily be seen that by adjusting the pitman 17 by means of the screw 19 and nuts 21 22 the bits 14 will be raised or lowered and will cut more or less, as required.
23 is a socket cast upon the lower half, 12, of the eccentricstraps, and pivoted to it is a finishing-cutter arm, 24, which follows behind theroughing-cutters above mentioned, and the lower end of this arm is provided with taper socket-holes 25 26, which receive the correspondinglyshaped ends of the finishing-cutters 27.
28 is a pitman having rigidly secured to its end a stud, 29, which receives the cutters 27, and its other end is hinged to a socket, 30, formed integral with the regulatingscrew 31, passing through the girder 32, and provided with adjusting-nuts'33 34.
35 is a bar extending across the framefrom side to side, and it is provided with a series of angleguards, 36, secured thereto by bolts 37 in such a manner that a guard extends between each pair of the pitmen 17, so as to prevent any lateral play of the cutterarm 12. One end of a spiral spring, 38, is connected to the lower end of the pitman 17, and its other end to a stud, 39, upon the cutter-arm 12,
' The proportions of these pulleys are such that 1-2 and iii are rails, upon which slide the l bed-pieces at 4:5, and upon the tops of these bed-pieces at one end is secured a cross-rail, 46, to the under side of which is secured a screw-box, 47, through which passes the feedscrew 48, which is suitably mounted in boxes secured to the f ame-wor: 49. A similar cross-rail, 50, is mounted upon the bed pieccs it and 45, so as to be adjusted with reference to the rigid rail 46, and this may be moved to or fro to correspond to the size of the stone to be cut.
51 51 are standards upon the cross-rails +16 50, and may be adjusted thereon by means of the eye-pin 52 being set in the holes 53, said pin acting as a stop against the angle-brace block 54-, extending across the rails and rigidly secured to the standard by the bolt 56 56 are adj USblllg-SCIQWS on the standard, and serve to adjust the stone and form a firm bed for it when its surface is irregular. A similar adjusting-screw, 57, is mounted in the for ward ends of the cross-rails 46 50, to furnish a bearing for the forward edge of the stone undcrthe same condition. Of course,after one side of the stone has been dressed, these ad j Listing-screws are not necessary, as the dressed side rests evenlyupon the carriage, and they are then turned so that their ends are below the level of the carriage and standards.
58 is a pulley on the shaft 4, from which a belt, 59, runs to the pulley 60 on the countershaft- 61., journaled in boxes on the timbers 2 and 3. Upon this shalt 61 is a smaller pulley, 62, from which a cross-belt, 63, runs to a pulley, (it, on the feed-screw 48, and when the main shaft 4: is set in motion the carriage is moved forward.
(35 is a pulley on the shaft 4, from which a belt, 66, runs to the pulley 67 on the countershaft 68, journaled in boxes upon the timbers 2-and 3. On the lower end of this shaft (58 is a large pulley, 69, having a cross-belt, 70, to the smaller pulley 70 on the feed-screw 48.
in practice the stone will be fed forward at a speed of, say, twelve to eighteen inches per minute, in proportion to the solidity of the stone, and it will be run back to take a new cut at, say, twenty or thirty times the speed that it is fed forward; and, likewise, the general p roportions of the various parts of the machine will be varied according to the size of the ma; chine and the kind of work it is to perform. In Fig. l I have only shown asingle pair of cutting-arms, to avoid complication; and in the plan view I have shown five sets of them, of course it being understood that the number of these cutters will correspond, as above indicated, to the rest of the machine.
71 is a bar, one end of which is rigidly scoured to the cross rails 46, and it passes through an opening, 72, in the rail 50, and extending a suitable distance beyond. 73 is an adjustable standard sliding upon the bar 71, and it may be secured at any desired point by the pin 74 in one of the holes 76.
75 is an adjusting-screw in the top of the standard, to bear against the end of the stone.
S8 is a nut in the beam 3, through which passes a stud, 81, on the end of which is a loose steel disk, 85, which forms athrust-bearing for the end of the shaft 4.
The bolts 63 and 70 are provided with tighteners. (not shown,) which are similar to the one 82 shown in Fig. 4, which consists of a flanged roller, 81, mounted in frame 82 and pivoted to the timber by screw-bolt 83.
In Fig. 2 the line Y Y represents the surface of the stone, and 79 is a roller which bears against the face of the stone. This roller is journaled in a frame, 77, hinged to the cross timber 7S, and a spiral spring, 80, serves to keep it in contact with the face of the stone, and thereby keep the stone rigidly against the standards 51 51. A similar roller, '79, is mounted in a similar frame, '77, and it operates in the same manner as the roller 79.
, In operating the machine the carriage is 11 rst adj ustcd to suit the size of the stone about to be dressed, and the stone is then placed thereon and made solid by means of the adjusting- screws 56, 57, and 75. The regulating-screws 19 and 31 are then adjusted so that the cutters 14 and 27 are all uniform, and the belt from the engine to the pulley 7 is tightened, which starts the shaft 4 revolving and sets the cutters in motion. At the same time the belt 63 is tightened, which starts the carriage forward. While the carriage is being moved forward, the belt 70 is slack. IVhile the stone is being fed forward, the cutters let out the surface nearly to the proper size, and the following bush-hammer bits 27 take off alight cutfor finishing. After the finishingbits have reached the end of the stone, the belt 63 is slackened and the other belt, 70, tightened, which rapidly runs the carriage back to the starting-point, where another cut may be taken, or the stone turned and a new surface presented for cutting.
In practice the bed of the machine is suitably built upon a bed of masonry in such a manner that the rails 46 and 50 are at an angle of about fifteen degrees. This allows the spalls to fall by gravity to the ground. Consequently the surface of the stone is kept clean and the labor of one hand dispensed with.
Where irregular work is to be done-such as rccessing, molding, or paneling the surface of the stone-the cutter-bits are adjusted one below the other, to correspond to the design to be cut;and in fluting or otherwise ornamenting the stone, the plane-bits are removed from the cutter-arms, and fiuting or molding bits inserted; and by varying the shape of the bits and regulating the depth of their cutting it will readilybe seen that anyvariety of work can be performed.
In practice the main operating-shaft is set at an angle of about ninety degrees to the carriage; but this will be varied, under certain conditions, to suit a particular kind of work, should occasion requireas, for instance, in
cutting window-sills or other work which re quires the sides and base to be right-angular, while the top is sloping. In some cases this may be accomplished by elevating the end of the stone by the adjusting-screws 57, and in others the position of the shaft 4 may be varied, as before set forth.
Having thus fully described my invention what I claim as new and useful, and desire to secure by Letters Patent of the United States, 1s-
1. In a stone-dressing machine, a main 0perating-shaft provided with a series of eccentrics having arms 12, and pitlnen 17, having one end pivoted to the cutter-arms, and the other end pivoted to the frame of the machine, substantially as and for the purpose set forth.
2. In a stone-dressing machine, a main operatingshaft provided with a series of eccentrics having cutting-arms 12, and pitmen 17, pivoted to the cutting-arms, and having adjustable screws 19, secured to a fixed part of the frame, as and for the purposes set forth.
3. The combination, with the shaft 4, eccentric 10, and cutter-arm 12, of the pitman 17, one end connected to the cutter-arms and the other to the frame, and having guards 36 on each side thereof, as and for the purpose set forth.
eccentric 10, and cutter-arm 12, having removable bits 14 secured thereto, of the pitinan 17, one end of which is secured tosaid arm, and the other end to the adj usting-screw 19, mounted in the girder 20, and having the spring 38, removably secured to the lower end of said pitman, as and for the purposes set forth.
'6. The combination, with the main shaft4, having pulleys 58 65, and eccentric 10, rigidly secured thereto, of the cutter-arm 12, secured to said eccentric, and provided with pitman 17, its lower end connected to said arm, and its upper end to the adj Listing-screw 19, secured to the frame.
In testimony whereof I affix my signature in presence of two witnesses.
