PROVISIONAL SPECIFICATION.
Improvements in Guides for Stamp Mills.
I EDMUND MAJOR of Terraville in the County of Lawrence, and State of
South Dakota, United States of America, Millwright, do hereby declare the
nature of this invention to be as follows:-
This invention relates to an improved guide for stamp mills by means of which
the bearing or guide blocks for the stamp may be readily adjusted to take up wear
and a tappet may be removed from the stem without disturbing the entire guide.
The invention consists of a keeper adapted to be secured to the girt or rail and
a flange plate held removably thereon, and projecting over the front faces of the
bearing blocks.
There are vertical slots on the front of the girt into which the inner ends of the
keepers fit, the keepers, which have the shape of an open casing being secured in
place by bolts which extend through vertical slots in the girt and into the back
of the keepers. The sides of the keeper extend downward and are outwardly
inclined while the tops and bottoms of each keeper connect the sides with the
back. There are flanges on the front ends of the sides, near the middle of which
flanges there is a recess engaged by the flange plate which extends a suitable
distance beyond the said flanges, the plate being secured in place on the keepers
by means of a bolt passing through lugs or ribs on the inside of the keepers.
The rear end of the sides of the keeper is provided with lateral extensions or
flanges which are beveled to correspond to the inner faces of the flange plate,
the latter as well as the flanges of the keeper engaging the front and rear faces
of the corresponding guide block.
The inclined sides of each keeper engage the outer sides of the guide or bearing
blocks for the stems of the stamps in the usual manner, the sides of the guide
5 blocks being beveled to correspond to the inclination of the sides of the keepers,
and being also beveled at their front and rear faces to engage with the flange
plate, and the corresponding front faces of the side flange so that when the
keepers are adjusted on the girt the guide or bearing blocks are free to slide
up and out of contact with the keeper or are held firmly in place by adjusting
O the bolt which secures the flange plate.
When the guide or bearing blocks become worn, 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. The flanges and the sides of the
flange plate engage the front surface of the guide or bearing blocks, as previously.
5 described and to prevent the said blocks from working upward, each side of the
flange plate is preferably provided with a rearwardly extending rib adapted to form
its corresponding recess in the front face of the guide block when the corresponding
bolt is screwed up to firmly engage the sides of the flange plates with the front face
of the guide blocks.
There is on the lower ends of the inclined sides of the keeper an outwardly-
extending shoulder adapted to engage a correspondingly shaped notch formed in
the bearing blocks, the shoulder preventing the blocks from sliding downward and
out of engagement with the keeper.
By this construction, any one of the stems can be removed without disturbing
5 the entire guide and each individual guide block can be removed or adjusted to the
stem by simply loosening or removing its respective flange plate.

Improvements in Guides for Stamp Mills.
I, EDMUND MAJOR of Terraville, in the County of Lawrence, and State of
South Dakota, United States of America, Millwright, do hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :—
This invention relates to an improved guide for stamp mills, by means of which
the bearing or guide blocks for the stamp may be readily adjusted to take up wear,
and in which a tappet may be removed from the stem without disturbing the entire
guide.
The invention consists of a keeper adapted to be secured to the girt or rail and a
flange plate held removably thereon and projecting over the front faces of the
bearing blocks.
The invention also consists of certain parts and details and combinations of the
same as will be hereinafter described and then pointed out in the claims.
Reference is to be had to the accompanying drawings, forming a part of this
Specification, in which similar letters of reference indicate corresponding parts in
all the figures.
Figure 1 is a plan view of the improvement with parts in section;
Figure 2 is a front view of the same;
Figure 3 is a transverse section of the same on the line 3-3 of Figure 2;
Figure 4 is a transverse section of the flange plate on the line 4-4 of Figure 2;
Figure 5 is a plan view of a modified form of the improvement, parts being
shewn in section; and Figure 6 is a sectional front view of the same on the
line 6-6 of Figure 5.
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 are formed vertical slots C into which fit the inner ends of
the keepers D secured in place on the girt A by means of bolts E. Each keeper D
is formed in the shape of an open casing through the back D¹ of which passes the
bolts E, as plainly shown in the drawings. The sides D' of the keeper extend
downward and are outwardly-inclined as will be readily understood by reference to
Figure 2. The tops and bottoms D³ of each keeper connect the sides with the
back, so that the entire keeper is very strongly constructed. On the front ends of
the sides D are formed short sidewise-extending flanges D' at or near the middle
of which is formed a recess D' to receive a flange plate F extending a suitable
distance beyond the flanges D, as plainly shown in Figures 1 and 2. Each flange.
plate F is secured in place on the keepers D by means of a bolt G to a suitable lug
or rib D on the inside of the keeper, as illustrated in Figures 1 and 3. In the
modified form shown in Figures 5 and 6, the keepers D have sidewise-extending
flanges D' having their front faces bevelled oppositely to the bevel of the rear faces
of the flange plate F, so as to embrace the correspondingly bevelled faces of the
guide block. Against the inclined sides D2 of each keeper abut the correspondingly
inclined outer sides of the guide or bearing blocks H (which embrace the stem of
the stamp in the usual manner) so that when the keepers are adjusted on the girt A
by means of the bolts E, the guide or bearing blocks are free to slide up and out of
contact with the keeper or are held firmly in place by adjusting the bolt G. Ass
illustrated in Figures 1, 2, and 3, the rear flanges D' are omitted and the rear faces
of the bearing blocks H abut against the front of the girt or rail A.
In case the guide or bearing blocks become worn, they may be adjusted to the
stem by loosening the bolt G and placing a thin piece of wood or other material
between the keeper and guide block. The flanges D' and the sides of the flange &
plate F embrace the front surface of the guide or bearing blocks as previously
described, and to prevent the said blocks from working upward each flange of the

page_text: plate F is preferably provided with a rib F1, at back as shown in Figure 4 adapted
to bed itself in the guide block when the bolt G is screwed up. On the lower ends
of the inclined sides of the keeper is formed an outwardly extending shoulder (see
dotted lines in Figure 2) adapted to engage a correspondingly-shaped notch formed
in the bearing-blocks, the shoulder preventing the blocks from sliding downward
and out of engagement with the keeper.
It will be seen by this construction, that any one of the stems can be removed
without disturbing the entire guide and that each individual guide block can be
removed or adjusted to the stem by simply loosening or removing its respective
flange plate.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1. A guide for stamp mills provided with a keeper adapted to be secured to the
girt or rail and a flange plate held removably thereon and projecting over the front
faces of the bearing blocks, substantially as shewn and described.
2. As a new article of manufacture, a keeper made in the shape of a casing and
provided with downwardly and outwardly inclined connected sides, side flanges
