MACHINE FOR BREAKING STONE FOR PURPOSE OF MAGADAMIZING ROADS, AND FOR OTHER PURPOSES.

Specification of Letters Patent No. 1,660, dated June 27, 1840.

To all whom it may concern:

Be it known that we, NICHOLAS COOPER,

Jr., and TOWNSEND MGCONNEL, of VVheel-' ing township, Belmont county, and State of Ohi0,and lVM. E. LUKENS, of Short Creek, Harrison county, and State aforesaid, have invented a new and useful Machine for Breaking Stone for the Construction of to the annexed drawings of the same, making part of this specification.

Figure 1 is a perspective view of the machine. Fig. 2 is a cross section at the line 00 w of Fig. 1. Fig. 3 is a view of the rear end of the machine, the end ties and board being omitted in order to show the several parts. Figs. 4 and 5 another description of cylinder with swinging hammers. Fig. 1 is an end view and Fig. 5 a side view.

Similar letters refer to similar parts in the several figures.

De.s'c'ripti0n.The machine consist-s of the following principal parts, viz: the frame, the cylinder, the grate, the battery, the feeding plane, and the cap or hopper.

The following is the size and construction of a machine adapted to a four horse power. The machine however may be varied to suit any power.

Part 1st, the frame, consists of four posts A of suitable sizesay 4 inches by 5-two of which are 5 feet high the remaining two 4: feet 9 inches, being 3 inches shorter, in order that the battery B, which rests thereon, may not rise higher than the top of the other posts. These are connected by four sideties C of the same size and 3 feet 6 inches long between the tenons (the two uppermost on which the cylinder rests) being placed 2 feet from their upper surface to the bottom of the machine, the other two at any convenient distance below; also four end ties D of the same size and 2 feet 1 inch between the tenons, the two front ones at the height of 19 and 38 inches from the bottom, the twoback ones at the height of 14 and 30 inches, respectively. The spaces between the two side ties on each side are filled with plank E 2 inches thick and rabbeted into the corner posts at each end. The spaces above the ties are also filled with plank two inches thick and inserted into the. corner posts by plow:

and groove in such a manner that they may be easily drawn out. Thenwhole is bound together by bolts of iron F, two running lengthwise and six crosswise of the frame.

Part 2nd, the cylinders: This consists of an axle Gr, 2 inches in diameter, on which are fastened two strong metal heads H, 14 inches.

in diameter, having four holes drilled in each. On these areplaced four metal staves. I, 2 1%. niches long, 2 inches thick, and of such a width as for each tov form one fourthof' the circumference of the cylinder. These are fastened to the heads by bolts passing through, holes corresponding with those inthe heads and by two strong iron bands (I, F ig. 3, received in rabbets formed for the purpose on each end of the cylinder. Along the center of each stave are four rectangular hol'es 2. inches long and 11}. inches wide at the surface and somewhat less at the inner.

side of the stave in which the hammers, K

are inserted. The hammers K are 2:1 inches wide, 11}- inches thick at the base, and about '1 inch at the point and rise about 4 inches from the surface of the cylinder, having the front edge faced with steel and of an oval shape. They are inserted into the staves. at. an inclination backward of 15 degrees from. the center of the cylinder and are firmly fastened by means of a key passing through the,

shank on the inside of the stave. At the back of each hammer is a triangular brace L, molded with the stave, rising about 3% inches from the surface and extending from the base of the hammer to the edge of the stave, against which the hammer .restsfor additional security. The hammers are so arranged that those only whichare on opposite sides of the cylinder run in the same orbit or circle. The most suitable velocity is about 350 revolutions of the cylinder per minute.

Part 3rd, the gate M: This is situated in' front of the cylinder and is formed of straight bars of iron, one half inch thick and one and three fourths or two inches wide, having their inner edge laid with steel to prevent its wearing and extending from the battery B down to some distance below the center of the cylinder at an inclination from the perpendicular of about 35 degrees, the ends being inserted into pieces of metal made fast to the sides of the frame.

The

bars of the grate should be placed at such a distance from the pointsof thehammers and from each other as to allow the stone' to pass. out of the machine when sufficiently broken and not before.'

Part 4th, the battery, is a rectangular. plate 13,24 by 28 inchesv and three inches thick, placed on the topof the frame to stop the stones as they are thrown up andcause .them 'to fall back on the hammers, the under; a side being plain, or set with knobs, or pros jections of the size and shape of half a i hens egg to'facilitate the operation of breakj ing. It is held in its placeby bolts N, pass-' ing from the top to the bottom of the frame.

4 Part 5th, the feeding plane. This is situated directly over the" cylinder and consists of a plate of rolled or cast iron O, having an inclination of45 degrees, over whichthe stones pass from the hopper P tofall upon the revolving hammers, and having attached to it bars 'Q,of iron, passing downward-between the hammers, so as to prevent the stone from touching the body of thecylinder. The bars have such a curvature that they always form an obtuse angle with the face of the hammers thereby removing all liability of the stones being caught between the. bars and hammers. V

Part 6th, the cap or hopper P: This is merely an addition to thefeeding plane, and consists oftwo planks pp, 3 feet long, 10

inches wide, and 2 inches thick,.eXtending lengthwise of the frame from the middle of the battery to the back part of the frame, connected by two planes R, inclines to 45 degrees in the opposite directionfrom that of the feeding plane, with which one of them" forms a right angle (nearly) so thereby .pre-

venting the stone being thrown out by the hammers; The other lies directly over the battery, and forms withthe sides a kind of hopper P, into which the stones are thrown.

It is fastened on by small iron bars extending down thesides and bolted through the sides ofthe frame. 7

Every part of the machine exposed to the action of the stones must be covered with a thick sheet,or boiler iron. V

The following is a description of a cylinder with flexible hammers, which insome respects is preferable to that before described. and may be substituted therefor; it is this: Having'onfa wrought ironshaftGr, Fig. '4: a suflicient number -of cast iron rings h, about 18 inches in-diameter and 1?}- wide .(each' ring beingbanded with "wrought iron bands)- to make thedesired length of the 'cylinderby leaving an inch space between them. The"hammersgareplaced in these spaces and are held in their places by rods 1" of iron" inch in diameter which pass through them from one endof the cylinder to theyother immediately under the rim of the ringsand through ears amolded in the angles between the rim and the arms, [a hammer ,K being placedin every other space on each rod. That part [of the hammer which presents itself outside the cylinder ismade in the same form as the stationary ones, with theexceptionof their being one inch instead of one and a half inches thick The hammers swing looseon therods and are thrown out by centrifugal force.

Operation; The stones to be broken are thrown into the hopper on the top of the machine, pass thence along the feeding plane to fall on the revolving hammers, which .move in such amanner as to strike the stones upward, throwing them against the battery, their escapebeing, prevented by a grate in front of the cylindersuntil they are broken. sufficiently smalltop'ass between the bars or at-the point of the hammers fromwhence they are conducted to the rear end of the machine byan inclined board 8, Figs. 1, 2,

and 3.
