W. L. ROSS. SUB'AQUEOUS ROCK BREAKING CHISEL:
No. 531,334. Patented Dec. 25,189
UNITED ST TES PATENT QFFIICE.
.1 WILLIAM L. ROSS, or NEWARK, NEW JERSEY, ASSIGNOR To P. SANFORD ROSS, OF SAME PLACE.
SUBAQUEOUS ROCK- BREAKING CHISEL.
SPECIFICATION forming part of Letters Patent No. 531,334, dated December 25, 1894.
Applicatio'nfiled July 11, 1894. Serial No. 517,176. (No model.) I
To all whom. it may concern.-
Be it known that I, WILLIAM L. Ross, a citizen of the United States, and a resident of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Subaqueous Rocka vide a removable point for the body of the chisel.
In the patent fora subaqueous rock breaker, No. 517,556, granted to P. Sanford Ross April 3, 1894, there is described a series of iron chisels weighing each about six tons, which are hoisted by means of a derrick to a considerable height and dropped upon the rock below. The enormous force of the blow disintegrates the rock, and although these chisels are provided with steel cores welded in at their points as referred to in the said patents, nevertheless the points will of course wear out in time and require to be renewed. It has been found that there is great inconvenience and expense, both of time and money, involved in renewing the points on account of the great weight, and size of the chisels. They have to be unmounted from the derrick equipped to effect the needed repair. This takes several weeks of'valuable time from the working period of the chisels and adds to the expense of shipment and actual repair. To save this expense and trouble I provide according to my invention each chisel with a removable point, which, when repair is needed,
may be detached and sent to the shop without unmounting the chisel. Eachchisel moreover may have more than one point, so that while one point is at the shop another may go fixed in its place and the chisel thuskept The invention consists of the construction hereinafter set forth.
In the drawings, in which like letters designate similar parts throughout the several views, Figure 1 is a side elevation of the lower end of a rock-breaking chisel embodying my invention. Fig. 2 is a longitudinal sectional elevation of the point of the chisel as connected to the body of the chisel. Fig. 3 is a longitudinal sectional elevation taken on the line 3- 3 of Fig. 2. Fig. 4. is a similar view to Fig. 2, the parts being disconnected and the lower end of the body of the chisel being ,turned through a right angle. Fig. 5 isa transverse sectional view on the lines 5-5, of Fig. 3, showing the parts in locked position, and Fig. 6 is a sectional view on the same line as Fig. 5 but showing the parts in unlocked position. I
Referring more specifically to the drawings, A is the removable point and B is the shank of a chisel embodying myinvention.
of the point Ayis provided with a socket D, v
adapted to receive the stud E of the shank B. The stud and socket are provided with corresponding projections and recesses, which when the stud is inserted within the socket and turned through a right angle, interlock and unite the shank and point rigidly together. As shown in the drawings, the stud has four segmental projections, b b, c c. The projections b and e are on one side of the stud and separated by the recess cl, and the projections b and c are on the opposite side and separated by the recess (1'. Theextreme lower end 6 of thestud is tapered or made conical. The socket D, which is made to correspond with the stud has a tapering socket f to receive the end 6, and four segmental projections g, g, h, h. The stud has an aperture is V and. the socket has corresponding countersunk apertures Z and Z" for the reception of a locking bolt F. In connecting the point and shank of th chisel, the stud E is brought opposite the 7 bottom the shank and stud are turned through a right angle, so that the projections 19, c and b, c fit respectively beneath projections 9, h and g, h, the projections g, g of the socket filling the recesses (Z d of the stud. This brings the apertures 70, Z and Z into register and the bolt can then be passed through them to firmly lock. the parts together. I prefer to solder the head and nut of the bolt in their eountersinks, to hold the bolt rigidly in place and prevent wear.
By means of the projections and recesses with which the stud and socket are provided as herein shown and described, it will be seen that avery large extent of wearing surface is provided for these parts which will effectually distribute the impact when the chisel falls.
Various changes which will readily suggest themselves to one skilled in the art might be made without departing from the spirit of my invention.
What I claim as new, and desire to secure by Letters Patent, is-
1. In a sub-aqueous rock-breaking chisel, the combination of a long heavy shank provided with a stud at its lower end, a removable point provided with a socket adapted to receive the stud of the shank, the socket and stud having projections and" recesses which, when the stud is inserted within the socket and turned through a given angle, are adapted to interlock, and means for maintaining the parts in locked position whereby the point and shank are rigidly and detachably united, substantially as set forth.
2. In a sub-aqueous rock-breaking chisel, the combination of a long heavy shank provided with a stud at its lower end, a removable point having at one end a cutting tip and provided with a welded in steel core extending upward from the tip and at its other end provided with a socket adapted to receive the stud of the shank, the socket and stud having projections and recesses which, when the stud is inserted within the socket and turned through a given angle, are adapted to inter lock, and means for maintaining the parts in locked position whereby the point and shank are rigidly and det-achably united, substantially as set forth.
3. In a sub-aqueous rock breaking chisel, the combination of a long heavy shank provided with a stud at its lower end, a removable point provided with a socket adapted to receive the stud of the shank, the socket and stud having projections and recesses which, when the stud is inserted within the socket and turned through a given angle, are adapted to interlock, and a removable bolt passing through the socket and stud for maintaining the parts in locked position whereby the point and shank are rigidly and detachably united, substantially as set forth.
4. In a sub-aqueous rock breaking chisel, the combination of a long heavy shank provided with a stud at its lower end, a removable point having at one end a cutting tip and provided with a welded in steel core extending upward from the tip and at its other end provided with a socket adapted to receive the stud of the shank, the socket and stud having projections and recesses which, when the stud is inserted within the socket and turned through a given angle, are adapted to interlock, and a removable bolt passing through the socket and stud for maintaining the parts in locked position whereby the point and shank are rigidly and detachably united, substantially as set forth.
5. In a sub-aqueous rock-breaking chisel, the combination of a long, heavy shank provided with a stud E at its lower end, a removable point A provided with a socket D adapted to receive the stud of the shank, the socket having projections g g and h h and corresponding recesses, and the stud having projections b b, and c o and recesses 61 d which, when the stud is inserted within the socket and turned through a given angle,are adapted to lock, and a removable bolt F passing through the socket and stud for maintaining the parts in a locked position whereby the point and shank are rigidly and adjustably united, substantially as set forth.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
