JULIUS G. DICKEY, OF SARATOGA SPRINGS, NEW YORK.

MILL-STEP.

Specification of Letters Patent No. 13,161, dated July 3, 1855.

To all whom it may concern:

Be it known that I, JULIUS C. DICKEY, of Saratoga Springs, in the county of Saratoga and State of New York, have invented a new and Improved Mode of Constructing Counter-Bridges and Tram-Blocks for Adjusting Grist-Mill Spindles and other Vertical Shafting; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, forming a part of this specification.

The nature of my invention consists in constructing a counter-bridge and tramblock for adjusting grist mill spindles and other vertical shafting and applying a roller to the lower end of the pot which contains the mill spindle, and also applying to the said roller a lever made wedging at the end where it comes in contact with the roller, and thus by raising the lever the roller is forced up an inclined plane and thus the spindle is raised or depressed, also securing the tube (which contains the pot) to the tram-block foundation by means of cams, said cams being pressed against the tube be tween the tube and uprights cast on the tram-block foundation, for the purpose of giving the spindle its lateral motion.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

I construct my counter-bridge and tramblock of cast or wrought iron.

Figure 1, is a perspective view, and Fig. 2, is a cross section of the same.

In Fig. 1, A, shows the mill spindle; B, the pot; C, the hollow tube; D, the roller; E, the lever; F, F, F, the cams, and H, the tram-block foundation.

In Fig. 2, A, shows the mill spindle; B, the pot; C, the hollow tube; D, the roller; F, F, the cams, and H, the tram-block foundation.

The spindle A, in Fig. 1, is inserted into the pot B, and the pot B, is inserted into the tube C, and on the lower end of the pot B,

are two flanges cast with slots in the same,

and into said slots I insert the ends of the roller D, which is provided with a tenon on both ends; and on the outside and near the lower end of the tube C, I cast a flange, and on two sides of said tube and opposite each other I make slots passing up a short distance above the flange, in the body of the tube, and forming an opening through the tube above the flange. The lever E, I make with a tenon on both sides which are inserted in the opening on both sides of the tube C, and rest on the flange cast on said tube. I also make another slot in tube C, forming an opening through the body of the tube, and the flange also, for the lever to work in; the lever being made sufliciently large to fill up the space between the flanges on the pot B, the roller D, resting on the lever E.

In securing the lever in the tube C, I pass the tenon 0n the same through the opening in the tube C, above the flange sufliciently far to allow the tenon to be passed through on the opposite side, and then raise the lever up into the slot made for that purpose. The lever where the roller rests on it is made wedging so that by raising the lever the roller is made to roll up an inclined plane, and thus raise the pot which contains the mill spindle. The lever may be raised or depressed by means of a screw, or otherwise. The tram-block foundation H, I make with an opening in the center into which the tube C, is inserted and on the edge of which the flange on the tube rests, the opening being sufliciently large to allow the tube to be moved to any desirable position, and the length of the tube below the flange being made equal to the thickness of the tram block foundation. The cams F, F, F, I make with a slot in them and make them wedging on one side of said slot securing them to the tram-block (H) by nuts and bolts (6) and by pressing them in between the tube C, and the uprights cast on the tram-block foundation which passes through said slots, I am enabled to secure the tube C, firmly to the tram-block foundation and give the spindle its lateral motion.

In Fig. 2, A, shows the mill spindle; B, the pot, C, the tube; D, the roller; F, F, the cams, and H, the tram-block foundation. The tram-block foundation H, may be secured in any desirable position by means of bolts or otherwise.

I claim- The application of the roller D, and lever E, for adjusting the height of the mill spindle when the latter rests in the tube C, and said tube is secured to the tram-block in the manner set forth.
