TOOL FOR WORKING STONE AND OTHER MATERIAL.
Application filed May 24,
To aZZ whom it may concern:
Be it known that we, ANDREW S. REID and ROBERT REID, of Beverly, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Tools for Working Stone and other Material, of which the following is a specification.
Our invention relates to improvements in tools for working stone and other materials;
IO and the object is to produce a tool for drilling, pounding, cutting, polishing, and otherwise working upon stone, and the tool may also be used in various other ways.
In the accompanying drawings, which illustrate a construction embodying our invention, Figure 1 is a perspective view looking at one s1de of the machine. Fig. 2 is a side elevation of a portion of the machine. Fig. 3 is a plan view, partly in section, taken on the line 3 3, Fig. 2. Fig.4is a longitudinal sectional view on the line 4 4, Fig. 5. Fig. 5 is a side view of the tool with part of the casing removed. Fig. 6 is an end view of the tool with part of the casing in dotted lines to show the interior parts. Fig. 7 is a sectional view on the line 7 7, Fig. 5. Fig. 8 is a detail sectional view of part of the operative mechanism.
Like letters of reference refer to like parts 3 throughout the several views.
The hollow column A is suitably mounted in the base A, so as to be revolved thereon at will, and surrounding said column is a sleeve A capable of vertical adjustment on said column and is keyed thereto, preventin rotation by the spline A workin in the eyway A Figs. 1 and 3. Extending outward from said sleeve and forming a part thereof is the bracket A carrying the table A, to
4 which is secured the electric motor A, controlled by the switch A and having the usual in and out wires A A On the shaft B of said motor is a pulley B for transmitting the motion of said pulley to the operating mech-- anism. On one end of the shaft B within the casing B is located the pulley B secured thereto by a suitable set-screw, and around said pulley B and pulley B is located the belt B for communicating power from the motor A to the shaft B From one side of the sleeve A extends the arm B having the upwardly-extending branch side arms B B, which are bolted to the casing B and support the same at the inner end.

the outer end of said casing B is an eye F, with which engages the hook F secured to one end of the elevating-rope D which extends upwardly and over the pulley F on the the shaft E to the drum D, fast on the shaft D and mounted in the supports O and D of the plate O, suitably bolted to the top of the casing B. wheel D which meshes with a smaller gear O, fast on the shaft O mounted in the bearing O of the plate O.- Beyond said gearing C is another gear C, fast on said shaft G with which is adapted to en age the pawl D,
winding drum in any desired position. Beyond said gear O there is a wheel 0", fast on the shaftO and by means of which the Winddesired, the sleeve A and the casing B. Another rope D has a hook F at its upper end secured to the eye F 6 at the top of the column A, and said rope extends downwardly and around the pulley E and up around the pulley F and down to the winding-drum D, so that by means of these two ropes D and D and the cooperating mechanism the sleeve A and the casin B may be vertically adjusted to any desire position.
As shown in Fig. 6, the casing B consists of two sides and a top, and on said casing is adapted to be moved to any desired positlon the tool which forms the subject-matter of this application.
The tool has two side plates G, with inwardly-extending plates Gr inclosing the arm and the casing B at that point Where the tool is located. These plates Or have downwardly-projecting plates G and extensions G which form into the column G Figs. 5, 6, and 7. This construction covers the interior working parts of the tool and protects same from excess of dust and dirt.
The bolts J pass through the sides G and support the standards K, carrying bearingblocks K, in which is mounted the shaft B and said shaft is keyed by the spline L to the eccentric ring L, surrounded by the eccentrio-ring M, which has a hollow vertical downward collar N, in which freely Works the sleeve 1 having a pin N working in the slot N of the hollow collar N, forming a loose oint.
The screw-threaded rod N is turned at its shaft F and down and around the pulleyE on i On said shaft D is fixed the gearcarried on the shaft D, an hold the ropeing-drum D is operated to raise or lower, as j upper end into the sleeve N and at its lower end into the stud N 5 of the hub N A spring P bears at its upper end against the flange N 7 on the collar N and at its lower end against the flange N of the hub N and operates to extend the loose joint between the sleeve N and the collar N. This construction forms a longitudinally-yieldable connecting-rod that operates to give a rebound blow to the tool S, so that the latter striking the work yields through the spring P and a crushing blow to the stone is avoided. By this means such a blow is. given that its effect does not extend beyond that part of the stone directly receiving the impact of the tool. Consequently the formation of the stone adjacent to the part struck is not affected and will not crumble. The hub N is mounted on the shaft N fast in the supporting-lugs P of the slide P movable in the opposite guides G held in place by the bolts G which, with the bolts J, hold the opposite plates together, as described. The guides are adjusted by the screws P. This slide P is interiorly screwthreaded, as shown, and adapted to mesh therewith is the screw-threaded upper end P of the rod P around which is located the collar P provided with the circular flange P, which is adapted to turn in the circular slot P of the column G Forming part of or screw-threaded to said collar I is a wheel 1 which is keyed by the spline P to the rod-plunger P Fig. 7. Said rod has an extended keyway P to allow for the upward and downward adjustments of said rod by the operation of the handle P By turnin the wheel or handle P the rod P is move either upwardly into the slide P or downwardly in said slide, so that the adjustment of the tool in relation to the Work can be had asdesired, and in said adjustments the key P remains in the position shown in Fig. 7,
with the slot P7 located in different positions, depending onthe upward or downward adjustment.
The lower endof the rod P is provided with a shoulder Q, on which freely rests the chuck R, having the inner packing S, within which is located the tool S, and the upper end thereof is held firmly in place by the setscrew S which passes through the chuck and the packing and engages the upper end of said tool and holds the same firmly in place, so that the tool while fast to the chuck moves with the chuck. This construction provides the necessary features for a successfully working toolviz., the tool must be loose on the stone to'work, it must be capable of turning, and it must also be capable of being lifted from the work at each stroke, allowing the tool to free itself from the stone and to revolve freely or change position by the action of the blow in hitting the' tool against the stone.
0 In the upper ends of the side plates G are mounted the shafts H, carrying the wheels H, on which are journaled the wheels L, so that the tool may be moved along the casing L by pushing on the wheel P The ends of the shafts H are eccentric thereto and may be operated by suitable handles H so that the shafts will raise or lower the frame G and hold it in any desired position on the arm or casing B.
The operation of the eccentric L will be clearly understood,-as during one part of the operation it raises the slide P and on the other part of the movement it moves the slide P down, the movement being yielding by reason of the spring P, thus giving a rebound blow to the tool S. Along the edges of the stone light blows are given to prevent clipping the edges. For light work the tool is carried a little farther away from the surface of the stone than would be the case for heavy work. Ordinarily the casing or arm B is adjusted so that thebottom of the tool S is about three-eighths of an inch from the top of the stone, and if it be desired to make further adjustment for different classes of work the same can be accomplished by operating the wheel or handle P as previously described.
It will be observed that the rotating shaft B lunger-rod P, and tool S are all in verticafalinement, so that the movement of the shaft is communicated in a direct line to' the tool. The tool, as previously described, may be moved in any desired position, vertically, radially, or laterally, as indicated in the two dotted positions shown in Fig. 1.
The reciprocative mechanism for imparting vibratory motion to the tool comprises the eccentric L, splined on the shaft B and the ring M on the eccentric. By using the term reciprocative mechanism in the claims it is not intended to limit them to the specific construction set forth, but to include any means capable of imparting a vibratory motion.
