COMPLETE SPECIFICATION.
Improvements in Anvils.
We, JOSEPH O'BRIEN, Master Blacksmith, of No. 56 Yeoman Street, and JEREMIAH
CAREW, Master Stone Cutter, of No. 23 Arcadia Street, both in the City of Boston,
in the County of Suffolk and State of Massachusetts, United States of America, do
hereby declare the nature of our invention for "IMPROVEMENTS IN ANVILS," and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
This improvement in anvils, consists, in substance, in an attachable and detachable
block for the full length and width of the anvil and having a working face on its
upper side ending at the horn of the anvil, which is set slightly below it, and also
having a tongue projection on and lengthwise of the under side of and integral with
it, in combination with a recess in the body of the anvil to receive said tongue-
projection of said block and means passing through the anvil-body and said
tongue-projection at the central and opposite end portions of the projection and from
side to side of the anvil, for fastening said projection of said block in said recess
and thereby drawing and holding the block to a tight and close seat on the anvil,
said means being preferably provided with appliances for fastening them against
accidental movement, all substantially as hereafter described, and pointed out in the
claims.
In the drawings, forming part of this specification,
Figure 1 is a plan view of the anvil.
Figure 2 is a side elevation.
Figures 3 and 4 are vertical sections, lines 3-3, and 4-4, figure 2.
Figure 5 is a view of the detachable block of the anvil and at its end toward
the horn.
Figure 6 is a section in detail, line 6-6, figure 1.
In the drawings, A is the body of the anvil; B is the detachable block having a
working face B and C is the horn.
The anvil-body A and born C otherwise than in accordance with this invention are
the same as ordinary.
The anvil-body A on its upper side is cut away from end to end, terminating at
the inner end C of the horn, in a vertical shoulder A2, having its angle a of junction
with the anvil-body rounded along and concave in a direction transverse to its length,
as shown figuro 6, for the full width of the inner end C of the horn, which is of a
width slightly less than the width of the anvil-body at said shoulder and the block
laps by said rounded corner at the opposite sides of the anvil-body. The block B
seats upon the upper face of the said cut out portion of the anvil-body covering its
full width and length and projecting at one end beyond the end of the anvil-body the
farther removed from the horn C.
The block is thicker than the depth of the cut out portion of the anvil-body and
it rises above the upper face of the horn, at its end toward said block.
The block, on its under side has a longitudinal vertical projection B₁ along and
for its central portion, and the anvil-body is suitably recessed to receive it but
slightly longer to allow lengthwise movement of the block on the anvil-body to enable
it to be seated on its upper side and to be brought into close endwise bearing
against the shoulder of the body. This tongue at its opposite end-portions has
horizontal round bores or holes D, D, in line with corresponding bores of the anvil-
body, and extending horizontally through said holes and from side to side of the
anvil all so that fastening pins E, E each of a taper, end to end, can be driven there-
into from side to side of the anvil-body, figure 3.

page_text: Again the tongue B' of the block B at its central portion has a vertical slot E³ and
the opposite sides of the body has corresponding vertical slots all for the reception of
upper and lower wedge-pins F, F2. The lower wedge-pin F2 has a shoulder 3 at its
opposite ends and it is inserted in said slots and thereby engaged with the sides of
the anvil-block, holding it against lengthwise movement through the slot as the upper
wedge-pin F is driven into place over it and through the slots, all of which together
with the end taper-pins co-operate to draw the block to a firm seat and to hold it on
the anvil-block and in close bearing at all parts thereof especially at the shoulder A²
and its rounded corner a as stated.
Preferably each round taper-pin E, E² as also the wedge-pins F, F2 severally
inserted and driven into place as stated, are made secure against accidental escap
escapement
or movement the former, that is the rounding-pins by driving a bolding-pin G through
them at their smaller end, figure 3, and the latter, that is, the wedge-pins F, F² by a
clamp H applied to their ends at the smaller end of the upper pin F and fastening
said clamp by a set-screw J.
An anvil constructed with a movable working face block all as above described
is important in many respects among others that it is essentially and practically as
serviceable as it would be were it solid; that when the working-block is worn so as
to be useless, it can be removed and replaced with another at comparatively small
expense; that the joint of block and anvil-body is perfect and more particularly so
because of the round of the corner of block and corner of shoulder of anvil; that
there is no possibility of accidental loosening of the fastenings of the block; and that
as the working face rises above and projects at the opposite sides of the horn it is
free and clear from interference therewith or of it with the work being hammered or
forged on the working face of the block.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
:-
First. In an anvil, the anvil-body cut away on its upper side and across its full
length and width terminating in a vertical transverse shoulder A2 at its end toward
its horn C which is integral with the body and having a vertical recess open at its
upper side and the block shaped to fill said cut away portion of the anvil-body and
its shoulder and to rise above the horn C, and having a central longitudinal tongue-
projection B to fit said, recess of the anvil-body, in combination with detachable
wedge or taper-pins driven through the anvil-body and said tongue-projection of the
block both suitably adapted therefor and from side to side of the anvil and located
at the opposite end and central portions of said tongue-projection and recess therefor,
substantially as described, for the purpose specified.
Second. In an anvil, the anvil-body cut away on its upper side and across its full
length and width terminating in a vertical shoulder A³ having a rounded corner a
at its end toward its horn which is integral with the body and having a vertical
recess open at its upper side and the block shaped to fill said cut away portion of
the anvil-body and its shoulder and rounded corner and to rise above the horn Cand
having a central longitudinal tongue-projection to fit said recess of the anvil-body,
in combination with detachable wedge or taper-pins driven through the anvil-body
and said tongue-projection of the block both suitably adapted therefor and from side
to side of the anvil and located at the opposite end and central portions of said
tongue-projection and recess therefor, substantially as described, for the purpose
specified.
Third. In an anvil, the anvil-body cut away on its upper side and across its full
length and width terminating in a vertical transverse shoulder A² at its end toward
its horn C which ist integral with the body and having a vertical recess open at its
upper side and the block shaped-to-fill said cut-away-portion of the anvil-body and
its shoulder and to rise above the horn C, and having a central. longitudinal tongue-
projection B to fit said recess of the anvil-body, in combination with detachable

page_text: wedge or taper-pins driven through the anvil-body and said tongue-projection of the
block both suitably adapted therefor and from side to side of the anvil and located
at the opposite end and central portions of said tongue-projection and recess therefor,
and means applied to said pins for fastening them against accidental movement,
substantially as described, for the purposes specified.
