MARBLE SAW.
No 20,981. Patented July 27, 1858.
H. L. ARNOLD, OF ELKHORN, YVISCONSIN.
STONE-SAWING- MACHINE.
Specification of Letters Patent No. 20,981, dated July 27, 1858.
To aZZ whom it may concern:
Be it known that I, HORACE L. ARNOLD, of Elkhorn, in the county of VValworth and State of Wisconsin, have invented a new and Improved Stone-Sawing Machine; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure 1, is a vertical section of my invention taken in the line 3 y, Fig. 3. Fig. 2, is also a vertical section of ditto taken in the line m, m, Fig. 1. Fig. 3 is a horizontal section of ditto, taken in the line 2, 2, Fig.1. Fig. 4:, is a detached section of a portion of the device by which the lateral feed movement is given the saws.
Similar letters of reference indicate corresponding parts in the several figures.
This invention consists in a peculiar arrangement of means for giving a lateral feed movement to reciprocating saws while the same are being operated, and also in a peculiar manner of arranging said saws in connection with their frames, the whole being arranged as hereinafter fully shown and described, whereby stone or marble blocks may be sawed either with curved or taper sides, with parallel sides, or, with irregular form, the same being used for monuments, fence posts, architectural purposes, etc.
To enable those skilled in the art to fully understand and construct my invention I will proceed to describe it.
A represents four uprights which are placed at the angles of a square and are attached to a proper base B. Each of these uprights has a rack (4, attached to it, all of which are shown in Fig. 3.
C, is a rectangular horizontal frame which is fitted within the uprights A, and at the front and back ends of the frame C, a shaft Z), is placed, a pinion a, being at the ends of each shaft, said pinions gearing into the racks a. The shafts b, are connected at one end by a shaft (Z, and gearing 6, see Fig. 3. V
In the frame C two guide parallel rods 7, are placed, one near each end, and to these rods a rectangular frame D, is suspended by plates g. The rods f, serve as guides to the frame D, the latter being a saw-frame and having a reciprocating motion given it by any proper means.
sides of' In each end of the saw-frame D, two screw rods h, it, are placed one over the other and in the same plane. The upper and lower screw rods have the same pitch, but they are rotated in reverse directions being connected at one end by gearing 2', i, the lower pinions 2", being allowed to move on their aXis so that they may be adjusted either in or out of gear with the upper ones 2', as may be desired.
In the saw frame D, at each end, two plates j are pivoted, one at each side, and to these plates rods 70, are attached, there being two rods 7c, at each end of the sawframe. On each rod is, there are placed two sliding blocks Z, Z, to the front ends of which the saws E, are attached and between which they are stained. 011 each screw rod it, it, there are placed two nuts m, m. These nuts are formed of two parts, the one part a, being merely caps which are removable at pleasure. The lower parts 0, of the nuts are each provided with lips 79, which fit into the back parts of the blocks Z, see Fig. 1. By this arrangement the saws may be properly strained without creating any bearing or pressure on the screw rods 72, it. The saws also by removing the caps 02, may be adjusted as desired. The inner ends of the plates j, are provided at the upper surfaces each with inclined planes 9, the use of which will be presently shown. To each plate j, a plate 1', is attached at right angles and to each plate 7*, two cranks s, s, are attached. The ends of these cranks are connected to slotted bars t, t, in which the ends of cranks a, are fitted, said cranks being connected to the heads 11, in which the saws are secured, said heads being so at tached to the blocks Z that they may turn freely as shown clearly in Fig. 1. To one end of each bar If, a pin a, is attached, and these pins fit in loops 5, at the inner ends of arms 0, which are attached to the frame D, at one side, said arms being rendered capable of adjustment longitudinally. The upper screw rods it, are connected at one end by gearing d, with a longitudinal shaft F, the bearings e, of which are attached to the saw-frame D.
G, is a sliding shaft which is fitted in a bearing f, attached to the frame C. The inner end of this shaft G, has a rack 9, attached, and this rack gears into a pinion k, which is fitted loosely on a shaft H, placed in a bearing 2', on the frame C.
The ends of the shaft H, are bent at right angles with each other as shown at j, 70,
i Fig. 3, the end j, projecting within and the end 70, being at the outer side of frame C On the end j, of the shaft H, a sliding collar Z, is placed, and to this collar a rack m, is attached which also gears into the pinions h. A rack '11,, is also attached to the collar Z, the latter rack being in a vertical position. The rack 11, gears into a wheel 0, which has a double pawl I, attached to it, and these pawls gear into a ratchet p, which is placed on the shaft F. The wheel 0, and ratchet p, are allowed to slide on the shaft F, but are made to turn with it, the usual feather and groove being employed to effect such result. To the axis of the ratch p, an arm 1", is attached and a rod 8, is attached to the upper end of said arm, the outer ends of the rod .9, and shaft G, are connected by a bar t. The lower end of the arm 70, of the shaft II has one end of a connecting rod 1/, attached. The opposite end of this arm is secured to a crank Q2, which is connected by gearing w, on the frame G, with a pinion a which gears into a vertical rack J, said rack being attached to a post 6", the lower end of which is secured to the base B.
The operation is as follows: The marble block to be sawed is placed on the base or bed B, below the frame D, the saws E, resting on the block. A reciprocating motion. is given the frame D, by any proper means and the saws E, are fed to their work by the weight of the frames C, D, and the parts attached to them, the frames being kept perfectly horizontal in consequence of the pinions 0, gearing into the racks a. As the frames C, D, descend a reciprocating or rock motion is given the shaft H, through the medium of the gearing a, and the pinion a", which gears into the rack J. The arm j, of the shaft H, gives a reciprocating motion to the rack n, and this rack actuates the wheel 0, and the double pawl I, rotates the shaft F, the latter rotating the screw rods h, h, at each end of frame D, so that said rods will be moved gradually toward or from each other according to the direction in which the shaft F, is rotated. A pattern K, is attached to the base B, and the outer end of shaft G, bears against said pattern. If double inclined sides are to be given the block the pattern is of the form shown in Fig. 1. This pattern as the frames C, D, descend, gradually draws the shaft G, outward, and the rack g, rotates the pinion 7L, the latter actuates the rack m, and gradually draws the collar Z, inward on the arm j, so as to decrease the length of the stroke of the rack n, and when the motion of the rack 14, ceases or nearly ceases in consequence of the end of shaft G being at the angle of the pattern, the pawl I, is changed or turned and a reverse motion is given the shaft F, the shaft G, being then pressed inward and the saws gradually fed toward each other. By this means the block will be sawed with curved or double inclined sides, the line a 2* Fig. 2, shows the form of the saw cut. once be seen that curved and irregular forms may be sawed by using corresponding shaped patterns. The saws E, may be set more or less inclined by adjusting the slotted bars t, through the medium of the arms 0. At the termination of each stroke of the frame D, the saws E, are slightly raised or tilted in consequence of the inclined planes 9, striking against the ends of the frame C.
It will at By this means the drip is permitted to carry 7 the sand below the saws. Blocks may be sawed with one side curved and the other straight, by shoving the lower pinions 6, out of gear with the upper ones i.
I do not claim the employment or use of screws h, h, for giving saws a lateral movement, for they have been previously used; but,
I claim as new and desire to secure by Letters Patent,
1. The particular means employed for operating the screws h, h, to wit, the rack J, and pinion a", gearing a, rack shaft I-I, rack n, and the wheel 0', pawl I, and pinion p, placed on the shaft F, the whole being arranged to operate as set forth.
2. I also claim in combination with the above, the racks m, g, attached respectively to the collar Z, and shaft G, and
used in connection with the pinion h, and
