IMPROVED STONE-CHANNELLING- MACHINE.

The Schedule referred to in these Letters Patent and making pari:` of the sama.

To all whom 'it may concern:

Be it known that GEORGE W. Brsnor, of Brooklyn, Kings county, New York, invented a newand improved Stone-Grooving Machine, for grooving pavements and other work; and that the following is a full, clear, andl exact description thereof', reference being had to the accompanying drawings, figures, and letters of reference thereon, in` whic -1 Figure l is a side elevation of his improved grooving-machine.

Figure 2 is a front elevation,

Figure 3 is a top view, and

Figure 4 is avertical section of the rotating cam, hammers, and chisels, detached fiomthe machine.

Similar letters of referencerefer to like parts in all the drawings.

The nature of the invention consists in the arrangement of a frame, which carries an engine and boiler, and a drilling or cutting-apparatus, the drills or chisels operating, on either or both sides, within or without said flame also, in providing a framerthat carries anengine, boiler, and a drilling or cutting-apparatus, with a. worm or spiral gear, to give motion to the same; and, also, in so arranging and combining a series of chisels that a rotating 'hammer may operate them all during its revolutions.

. To enable others skilled in the art to make and use the invention, its construction and operation will now 4be described.

The figures, l, 2, 3, 4, 5, 6, 7, 8, and 9, are 4parts of the frame which support various working-parts of the machinery.

A represents the boiler of an ordinary steam-engine.

B is the engine-cylinder.

C is the smoke-pipe to the boiler.

D is the connecting-rod, which is attached, in the rdinary way, to a crank-shaftfE, from which motion is imparted to the parts of the machine.

F is a bevel-gear on the crank-shaft, which drives another gear, G.

This gear Gis made fast upon an upright shaft, H,

- on the bottorn'of which there is a worm-gear, I, which works a pinion on the axle K. L is the fbrward axle of the machine.

. M M are driving-pulleys, attached to the outer ends of the crank-shaft, which drive, by means ofthe belts, the rotating hammer-shaft 0, by means of the pulleys N N. l

P Q are the .guide-plates, (through which the' chisels work,) and are made adjustable, by means ofthe slotted ears d d.

R R R are the rotating cams or hammers, which strike all the ,ohisels during the revolution of the shaft.'

It will be observed that these cams or hammers are so arranged upon the shaft that only one cam. or hammer is upon the 4chisels at a time, which arrangement contributes to the even and easy working of the maf chine, thereby requiring less power, which is a great advantage.

S S S are the chisels, which are plainly shown in all the igures.

These chisels arearranged with a collar, T, on them, which is made fast'by `means of a screw, or otherwise. Directly below this collar T, and around the chisels, are smallhelical springs, c, which bear,'at their upper ends, against the collar T, while their lower ends rest v against the guide-bar Q. p

The object and purpose of these springs are to react the chisels after receiving the blows from the hammers.

The revolving hammer-shaft O has its journals in sliding boxes, U, which are secured in the proper position, to give the requisite blow to the chisels, by the bolt and nut e, or other proper manner.

The crank-shaft is supported and has its journals in proper standards, V, attached to the frame-rails.

The shaft H has its bearings, at its upper end, in the plate 8, while the lower end rests in a cross-piece attached to the frame-work 9.

In this case is represented a series of cutters which workwithout the limits of the frame, but within the limits of' the track upon which the frame moves; but it is perfectly evident that the cutters may be worked outside of the track, by a simple transposition of the pulleys N and M, and the cam and hammers.

Should the pulleys N and M be moved within the frame, and the cutters, with their hammers or cams, be moved tothe extremities of the shaft, then could grooves `be readily cut on each side of the track, and onA the outside of both frame and track, and this, too, without any change whatever in construction of the machine. The guides which hold the cutters would, of course, have to be changed to the outside of the frame.

Motion being given to the crank-shaft, it imparts a motion, through the pulleys M and-N, by means of the belts l) b, to the rotary hammer-shaft, which, as it revolves, strikes the chisels singlygrand, as soon as the hammers have passed the chisels, they react, by means of the helical springs, ready for another blow.

The guide-bars are set in the right position to cnt deep or shallow grooves, and the hammer-shaft set to correspond for the proper blows.

0u the upper end of the upright shaft H, there is a bevel-pinion, which is worked from the gear F, on the crank-shaft, while on the lower end of the'shaft H is a worm-gear, which works a pinion on the rear axle, K, and, by their conjoint action, cause the machine to 4regularly progress forward, and a continuous feeding is hadfor the machine.

The feeding oi' the machine may be regulated, by the size of the gearing on the shaft H, to workslow or fast, at the option of the engineer.

The cams can be used instead of the hammers, or

the hammers can be substituted for the cams, the'cams giving a, sliding or gradual motion, while the hammers give a positive motion for the chisels or drills.

It will be seen that the worin, working in'fthe gear 0n the axle, turns the Wheels upon any suitable track or way, and, by means of `theweight 0f the machine resting ou thetrack, when thewheels are turned, the

friction of the wheels upon the track or way moves the machine, and thus the machine is fed at any desired speed. l

The object ot this iiictiou-feed is obvious, for the reason that, when .the machine, while in operation, is frequently obstructed and stoppedin various ways', the Wheels will turn on the track, and thus save the breaking of some part of the feed-works, whereas apositiv'e feed would break some part of the machine.

Having thus fully described the invention,

What is' claimed as new, and desired to be secured by Letters Patent, is n 1. A stone-grooving machine, upona frame, which carries an engine, and a boiler, and a stone-channelling or grooving apparatus, with reciprocating cutters, op-r erating in connection with the frame, substantially in the manner specified.

2. A frame which carries an engine, and boiler, and

a drilling, grooving, or cutting-apparatus, when provided with aworm and spiral gear, for the purpose of giving motion to said frame, upon any suitable track 0r Way, by means of friction` substantially as herein specified.

.3. Propelling a stoneLgmoving or cutting machine, or a frameof a drilling, cutting, or grooving-machine, by means of a worm, operate upon the wheels or' axles which support or carry said frame, substantially as specified.

`4. A series of vestical inclined chisels, of different lengths, placed,\one behind the other, in combination with a revolving hammer or cam, as described, whereby a positive motion is given to all the chisels, from a 'single hammer or cam for each series of chisels, substantially as set forth.

5.". The combination of a feedLmechanism, a stonechannelling or grooving machine, and a steam-engine, all operating substantially as and for the purposes set forth.

6. The combination of wheels having plane surfaces,

and which move upon a track having a plane surface, with the frame and propelling-mechanism for drilling, channelling, or cutting stone, whereby I am enabled to feed the machine without too positive a movement, substantially as and for the purposes specified.

1n testimony that lelaim the foregoing, 'I have hereunto set my hand, this 15th day of March, 1869.
