GUIDE FOR STAMP-MILLS.

SPECIFICATION forming part of Letters Patent No. 499,130, dated June 6, 1893. Applicationfilcd December 5, 1892- Serial No. 454,070. (No model.)

To all whom it may concern:

Be it known that I, EDMUND MAJOR, of Terraville, in the county of Lawrence and State of South Dakota, have invented a new and Improved Guide for Stamp-Mills, of which the following is a full, clear, and exact description.

The invention relates to improvements in guides for stamp mills such as are shown in the Letters Patent of the United States, No. 469,157, granted to me February 16, 1892, and in an application for Letters Patent of the United States, Serial No. 435,169, filed by me June 1, 1892, and allowed September 24, 1892.

The object of the present invention is to provide certain new and useful improvements in stamp mill guides, whereby the bearing blocks are securely held in place and can be readily adjusted Whenever desired on account of wear or other causes.

The invention consists of a keeper adapted to be fastened to the girt or rail, and formed at its rear with side flanges bearing against the front of the girt and adapted to receive the back of the bearing blocks.

Reference is to be had to theaccompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the views.

Figure 1 is a plan view of the improvement with parts in section. Fig. 2 is a transverse section of the same on the line 2-2 of Fig. 1;

and Fig. 3 is a sectional side elevation of one of the keepers, on the line 3-3 of Fig. 2.

The improved guide for stamp mills is provided with the usual girt or rail A secured by bolts or other means to the battery posts B of the stamp mill. On the front of the girt or rail A are formed vertical recesses G, into which fit ribs D projecting from the backs of the keepers E secured in place on the girt A by bolts F, passing transversely through the said girt, as plainly shown in the drawings. Each keeper E is formed in the shape of an open casing, the back E of which is engaged by the bolts F, and their heads extend into the casing, as plainly shown in the drawings. The sides E of each keeper extend downward and are outwardly inclined, as shown in Fig. 3, and the top E and the bottom E of each keeper connect the sides E with the b ack E so that the entire keeper is very strongly constructed.

On the rear of the sides E of each keeper are formed sidewise extending flanges E each having its front face beveled to receive the correspondingly-shaped rear side of the bearing block G fitting on the corresponding side E of the keeper and against the said beveled front of the corresponding flange E.

On the front ends of each side E are formed short sidewise extending flanges E, at or near the middle of which is formed a recess E engaged by a flange plate H extending a suitable distance beyond the short flanges E, as plainly shown in Fig. 1. Each flange plate H is secured in place on the respective keeper E by means of a bolt I held by suitable lugs or ribs E on the inside of the keeper and formed integral with the sides thereof, as will be plainly understood by reference to'the drawings. The inner face of each flange plate H is beveled to engage the corresponding beveled front side of the corresponding hearing block G so that the latter is engaged on three sides by the keeper and at its inner semi-circular recess by the stem of the mill. It will be seen that by screwing up the respective bol-t I for the corresponding flange plate H, the latter securely presses the bearing blocks held on opposite sides of the keeper in place thereon, and also presses the said bearing blocks in firm contact with the front beveled sides of the flanges E The sides of the guide or bearing blocks are beveled to correspond to the inclination of the sides of the keepers so that the guide or bearing blocks G are free to slide upward and out of contact with the keeper or can be held firmly in place by adjusting the flange bolt I, as above described. When the guide or bearing blocks become worn by the vertical movement of the stamp stem, they may be adjusted to the stem by loosening the flange bolt, and placing a thin piece of wood or other material between the keeper and guide block.

As shown in Fig. 1, the bevel on the front of the flange E corresponds with the bevel on the inner face of the flange plate H, so that the latter and the corresponding flange E securely hold the block in a dovetail formed by the flange E and the flange plate.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent "1. A guide for stamp mills provided with a keeper adapted to be secured to the girt or rail, and provided with inclined sides, integral flanges extending from the rear ends of the said inclined sides, the front faces of the said side flanges being beveled, and a flange plate on the front of the keeper to form with the inclined side and corresponding side flange a dovetail for the bearing block, substantially as shown and described.

2. A guide for stamp mills comprising a keeper adapted to be fastened to the girt or rail and provided with integral flanges extending sidewise from the rear ends of the inclined sides of the keeper, the front faces of the said side flanges being beveled, abearing block fitted on the adjacent inclined sides and beveled flanges of the said keeper and a flange plate held removably on the front end of the keeper and projecting over the front faces of the bearing blocks on each keeper, substantially as shown and described.

EDMUND MAJOR.
