J. B. S'AGKET. DRESSING. M'ILLSTONES.
Patented Mar..25,'1862.
Inveni'ar:
JOEL B.
SACKET, OF LA\VTON,
MICHIGAN.
MACHINE FOR DRESSING MILLSTONES.
Specification of Letters Patent No. 34,780, dated March 25, 1862.
1 '0 all whom it may concern:
Be it known that I, J. B. SAcKEr, of Lawton, in the county of Van Buren and State of Michigan, have invented certain new and useful Improvements in Machines for Dressing Millstones; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, in which Figure (1) is a plan of the top with the lid removed, Fig. (2) is a plan of the bottom, and Fig. (3) a front end View, representing the picks.
The nature of my invention consists in the combination and arrangement of such devices as will be hereinafter fully set forth.
To enable others skilled in the art to make and use my invention, I will now describe its construction and operation.
(A) represents the box in which is inclosed the carriage (B).
(C) is a cylinder operated by means of crank (W).
It should be remarked that the box (A) has a slot cut in its side for the purpose of allowing the crank cylinder to move back and forward with the carriage.
(D) is a large cog wheel encompassing cylinder (C) as fully shown one half of said cog wheel should be just doublyas wide as the other half as shown in Fig.
(b I) b) are pick handleswhich are pivoted independently through blocks (P P).
(e e e) are hooks attached to the picks.
(f f) are cords which connect said hooks to springs (g g g). It will be observed that the springs (g g g) are formed by being wound around rod (h) as represented in Fig. (2). Each one of the pick handles is provided at its outer end with a screw thread as shown in the drawings. 7
(a a) represent clamps between which the picks (a a: a) are secured by means of nuts (0 c) and (cl cl), thus it will be seen that the picks can all be set either in a straight line with each other, or irregularly as circumstances require. The face of the carriage is provided with a sheet of metal, which is cut in vertical slots, thus acting as guides to the pick handles, as seen in Fig. (3).
(u 14) represent small levers or bars pivoted to the face of the carriage on one side of each of the slots.
(b b b) are tacks or pins, thus it will be seen that any one of the picks can be suspended from operation simply by holding the handle up and adjusting the bar or lever beneath it.
(2' 2' 2') represent pins which are secured around the periphery of cylinder (C) in a spiral form, thus in the revolution of said cylinder the pins 2' will successively operate upon the picks. Any arrangement of these pins can be made, causing the picks to operate either simultaneously or alternately.
(E E) represent two cylinders, each of which is provided with pulley blocks (F F) and connected by cord (N). i
(I) is a cog wheel on cylinder (E), which is operated by the large cog wheel (D).
(G) is also a cog wheel of wider dimensions than the other.
(H H) are gear wheels arranged upon the sliding shaft (M).
(K) is a bevel gear wheel on the screw rod (0) and between the wheels (H H). The object of this arrangement will be more fully seen hereafter.
(Y Y) represent two guides located above cylinder (E).
(w a?) are uprights secured at each end of s(a1i d 1eylinder and pass up through the guides (r r) are two thumb screws which extend through ears on uprights (w w) as fully shown in Fig. (1). The ends of the screws (7 1 rest against the cross piece (S) of the carriage (B), thus by means of this arrangement the cord (a), which connects the pulley blocks may be loosened or tightened'at pleasure.
(79) represents a rod which is attached to the sliding shaft (M) and by means of which the cogs H H can be alternately thrown into gear with cog wheel (K), thus the carriage may be forced gradually in or out simply by turning the crank (WV) which will give the picks a uniformity of action over the surface of the stone.
(J J) represent two thumb screws which extend down from a cross piece in the carriage to the piece upon which. the rod (h) is secured. There is a groove on each side of the carriage for this piece to slide up and down in. Thus it will be observed that the force of the picks may be regulated by elevating or lowering rod (72 or the piece to which it is secured. Y
(t) represents a loop for the purpose of stopping the operation of wheels (H H) by locking them.
It should be observed that the carriage is provided at its bottom with small rollers for the purpose of enabling it more easily to be moved in and out.
The operation of my invention is as follows. The machine being properly placed, motion is given to cylinder (C) by means of crank (W). As said cylinder revolves the pins i i) on its circumference operates the pick handles (6 b b) as may be seen in Figs. 1 and 2. The large cog Wheel (D) imparts motion to cylinder (E) by means of cog wheel (I). Cylinder (E) receives its motion from cylinder (E) by means of a cord or band, which passes around the pulley blocks of both. The cog wheel (G) on cylinder (13) imparts motion to the bevel gear wheels on shaft and the said gear wheels (H H) operate the Wheel (R) 011 screw shaft Thus it will be obvious that when the bevel Wheel (H) is thrown in gear by rod (p) the carriage (B) will be gradually forced out, which will enable the picks to traverse the surface of the stone Without the machine being moved. As soon as the carriage is pushed out its full length the bevel wheel (H) is thrown in gear,
which immediately reverses the motion of the carriage. The object in having the large cog wheel (D) of an unequal width as already described is to give the picks an intermittent motion by sliding the cylinder (G) to one side till only the extended portion of the cog wheel (D) shall come in contact with cog (G). Thus it will be observed that the picks will be operated upon only during a part of the revolution of cog wheel (D).
Having thus fully described my invention,
pose set forth. J. B. SAGKET.
