DAVID E. BAUGHEY, OF ST. THOMAS PENNSYLVANIA.

MACHINE FOR LEVl-ILING MILLSTONES AND TRAMMING SPINDLES.

SPECIFICATION forming part of Letters Patent No. 224,812, dated February 24, 1880.

Application filed December '8, 1879.

To all whom at may concern:

Be it known that I, DAVE) E. BAUGHEY, of St. Thomas, in the county of Franklin and State of Pennsylvania, have inventedcertain new and useful Improvements in Machines for Leveling Millstones and-Tramming Spindles; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specij the same; and it consists in certain improvements in the construction of the parts, which Will be hereinafter more fully described, and particularly pointed out in the claims.

In the drawings hereto annexed, Arepresents the bed-stone, and B the spindle, which is journaled in the usual manner in the bridgetree 0. i

D represents a cylindrical tube, provided on four sides with set-screws E, by which the said tube or cylinder may be adjusted and firmly secured upon the upper end of the millspindle.-

The tube. D is provided at its upper end with radial flanges F F, supporting a disk or plate, G, of sufficient size and strength to support the runner-stone while the bed-stone is being leveled and the spindle trammed.

The plate G is provided with slots H H, ex-

' tending from near the center in diametricallyoppositedirections.

I I are clamps sliding in the said slots, and provided upen the under side of plate G with plates J J, slidingin suitable grooves or guides, and having set-screwsK K, by which the said plates and clamps may be secured in any desired position.

The plate G is provided with an opening, L,

below which slides a plate, M, adjustable by a set-screw, N, and forming an adjustable bearing for a vertical rod, 0, having at its upper end a handle, P, and provided at its lower end' with a screw-thread, so as to be vertically adjustable in an arm or bracket, Q, projecting laterally from the tube or cylinder D. Below the bracket Q, and connected to the latter by a vertical rod, R, is another bracket, S.

Upon the rod It is adjusted a spring, T, which serves to press a socket, U, sliding upon said rod, in an upward direction against the lower end of the adjustable rod 0, by which the said socket may thus be adjusted vertically to any desired position.

The socket U is provided with a horizontal arm, V, adjustable by a set-screw, W, and provided at its outer end with a slot, X, in which a slotted arm, Y, is horizontally and vertically adjustable by a thumb-screw and nut, Z A:

The arm Yhas at its lower end aholder, B, in which the pointed whalebone O, which serves as a trainniing and leveling tool, is adjustable by a set-screw, D.

E E F represent the supports for a swinging crane, G, by which the runner-stone may be lifted upon or off the machine.

The operation of my invention will be readily understood by those skilled in the art to which it appertains. It is simple, efficient, inexpensive, and easily operated; and it will be observed that while the machine is in use, owing to the arrangement of the plate G, the weight of the runner-stone is supported on tirely upon the bridge-tree, as when the mill is running, thereby preventing any damage to the floor, where the stoueis usually deposited, and also any deviation from the level and tram when the stone is replaced for operation.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States-- set-screws E, brackets Q S, and rod R, having spring T, with the socket U, having arm 5 V and start Y, and the threaded rod 0, working in bracket Q, all combined and operating substantially as and for the purpose herein set forth.

2. In a device for leveling millstones com structed substantially as described, the comown I have hereto affixed my signature in bination of the tube D, adapted to be adjusted presence of two witnesses. upon the spindle with the disk or plate G secured at the upper end of said tube, to support DAVID BAUGHEY' 5 the runner-stone during the operation of the Witnesses:

machine, as set forth. HIRAM BYERS,

'In testimony that I claim the foregoing as my EDWIN C. PATTON.
