M. DE CAMP.
Millstone Bush.
Patented May 24, 1859.
M. DE CAMP, OF SOUTH BEND, INDIANA.
MILLSTONE-BUSI-I.
Specification of Letters Patent No. 24,106, dated May 24, 1859.
To all whom it may concern:
Be it known that I, M. DE CAMP, of South Bend, in the countyof St. Joseph and State of Indiana, have invented a new and Im; proved Millstone-Bush; 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 specifica-tion, in which- Figure l, is a vertical section of my invention taken in the line w, at', Fig. 2. F ig. 2, is a horizontal section of the same,vtaken in the line y, y, Fig. l.
Similar letters of reference indicate corresponding parts in the two gures.
The object of this invention is to obtain a durable bush for the spindle of the bed stone, one that will admit of a certain degree of adjustability so as to conform in itself to the position of the spindle and be selfadjusting to a certain extent, one that will also insure a perfect lubrication of the spindle and admit of an easy adjustment of the followers to the collar of the same, and also protect the spindle from foreign substances that might otherwise work between the collar and followers and produce unnecessary friction and wear.
To enable those skilled in the art to fully understand and construct my invention I will proceed to describe it.
A, represents a rectangular metal box, which is fitted in the eye of the bed stone and secured therein by any proper means. This box has a tubular vertical projection B, at its center through which the spindle C, passes and in which it is allowed to rotate freely. On the spindle C, a collar D, is secured. This collar is cylindrical, is also hollow and fits loosely over the central tube B, of the box A, as shown clearly in Fig. l. 'Ihe lower edge of the collar D, is rounded or beveled at its inner side as shown at a. On the top of the box A, and between it and a cover E, a piece of leather or other suitable packing is placed, the cover E, being secured to the box A, by screws c. The collar D, extends upward through the center of the cover E, and it is encompassed by an annular flanch d, on the cover E, the flanch and collar being covered by a plate F, which is placed on a polygon ax, o-n the spindle C.
Within the box A, four vertical plates e, are placed, said plates being fitted between projections 7, on the inner sides of the box and resting on ledges g, on the inner sides of the box a short distance above its bottom. To the inner side of each plate e, two vertical and parallel guides z, it, are placed which receive the followers F. These followers may be of Babbitt or other similar metal and their inner surfaces are concave corresponding inversely to the surface of thc collar D, as shown clearly in Fig. 2. The backs of the followers F, as well as their sides are made of convex form, as shown clearly in Fig. l. Through each plate e, a screw z', passes horizontally and bears against the backs of the followers. Each screw i, has a serrated or toothed wheel z", on its outer end into which stops j, catch, said stops being attached to plates la, which lit in the top of the box and behind the plates e, see' Fig. l.
The box A, is supplied with oil which as the spindle C, `rotates, lubricates the followers F, and collar D, the oil passing up between the followers and the collar. The `oil is prevented from passing up between the tube B, and collar D, on account of the inner sides of the collar at its bottom being` rounded, and also by the space between the tube and collar being too eat to permit the oil to ascend freely. The followers F, are adjusted to the collar D, by removing the plate if, and turning the wheels vl, of the screws i, the stops j, of the plate 7c, preventing the wheels z", from casually turning. On account of having the followers F, of convex form they are allowed to adjust themselves to the spindle in case the latter is out of line. All heating of the spindle is thereby avoided.
The box A, may be of cast metal, the spindle C, of course being of wrought metal with a properly turned collar.
I do not claim broadly the employment or use of a hollow collar D, encompassing a tube B, in a box A, for such device has been previously used, but I am not aware that followers provided with convex sides have been used in connection with a collarD, to permit'the followers to conform to the position of the spindle in the event of the latter being out of line. Neither am-I aware that regulating or adjusting screws z', have been employed with serrated wheels e", at their ends and used in connection with stops j, to prevent the casual turning of the screws and the consequent misplacement of the followers. -I do not claim therefore broadly, irrespective of construction and arrangement flle employment 'or use of fadjstable f2. 'The sernated or .notched lwheels i, at-
followers. Neither do I claim adjusting l tached to the outer ends of the screws z, screws z', in themselves consderedgbut, When used in connection with the stops j,
I do claim as new and desire to secure by attahed Jto "the plates 70,' substantially as 5 Letters Patent, Eand .for the purpose specied.
1. The adjustable followers F, provided with convex sides and backs fitted Within, M DE CAMP 1, an oil box A, and arranged in relation with, Witnesses:
the collar D, of the spindle to operate as CHARLES M. HEATON, l0 and for thepurpose 'setf'forth I CHAS. B. CHANDONAI.
