anvils more especially designed for heavy work as, for instance, in steam or power hammers.
The primary object of this invention is to so construct the base or body of an anvil on which heavy work is to be done that said body will be able to successfully withstand the great stresses or strains to which it may be subjected and will not be liable to be broken down centrally of the body.
Another object is to form said body of substantially verticalv and "suitably contoured metal plates arranged side by side and close together and removably secured in place so that plates forming only a. portion of said bodycan be readily replaced, if required, independently of the remainder of the plates.
Another object is to form a seatfor the anvil-cap by the tops of the central portions of said plates and to clamp said plates together at such points in relation to said seat that the hereinbeforementioned body is rendered adequately strong throughout,
7 and "a further object is to have each of said plates interchangeable with any other of said plates so that should the seat-forming top edge of a plate show premature wear said plate can be interchanged with any other plate showing less or no wear, to the end of'prolonging the life of the anvil:
Another object is to render my improved anvil-body simple and durable in construction. I
lVith these ob ects inview, and to attain any other object hereinafter appearing. this invention consists 1n certain features of con Fig. 1. Figs. 3 and 4 are vertical sections taken along the line 3-3 and line H, re-
spectively, Fig. 1.
Referring to said drawings, 5 indicates the base or body of an anvil more especially adapted for use as a portion of a steam or power hammer. Said body forms a laminated base, being shown composed (see lugs. 9,. .3 and 4t) ot a substantially horizontal row of substantially vertical plates (5 preferably of steel, and said plates extend transversely of said row and are arranged on edge. Adjacent plates of said row of plates are arranged side by side and contiguous and tied or secured together as will hereinafter appear. The plates 6 extend from end to end and from top to bottom of the body The upper portion of each plate 6 is provided centrally between the ends of the plate, as shown in Fig. 1, with a. seat'which is formed by the bottom 7 of the lower portion of a recess 8 formed in said plate at the top and centrally between the ends of the plate. The recess 8 in each plate 6 extends laterally through and longitudinally of the plate, and the upper portion of said recess is shown extend ing endwise of the plate beyond the lower portion of said recess. The recesses 8 in adjacent plates 6 correspond in dimensions and register with each other and are in line "longitudinally of the row of-plates, and the bottoms 7 of the lower portions of said recesses'are flush, as shown in Fig. 3, so that said bottoms form a continuous seat extending from the outer side of one outer-most plate of the row of plates to the outer side of the other outermost plate of said row of plates, and consequently from side to side oi the body 5. The end walls 9 of the lower portion of the recess 8 in each plate are shown undercut, (see Fig. 1) and seated n the bottoms 7 of the lower portions of the recesses 8 in the plates 6 is an anvil-cap 10 on which hammer or forging operations are adapted to be performed, and the dovetailed lower portion of said anvil-cap and a gib 12 occupy saidportions of said reccsses. I
Each plate 6 (see Fig. 3) is provided, under the seat 7 formed thereon, with a bolthole 14 which extends laterally through the plate. The holes 14 in adjacent plates 6 are arranged in line endwise and correspond diametrically, and said holes are snugly occupied by the shank 15 of a bolt which has its head 16 arranged at and abutting against the outer side of one of the outermost plates of the row of plates, and said shank extends beyond the outer side of the other outermost plate of said row oit'plates, and a nut 17 is threaded onto said shank and abuts against said side oi the last-mentioned outermost plate. Said nut is tightened against the adjacent plate so that the plates are clamped together by and between said nut and the bolt-head 16.
Preferably the upper portions of the plates 6 are tied or secured together at two points spaced longitudinally of the plates at each side of the seat formed on said plates for the anvil-cap, and at each of said points a bolt having its head 18 (see Fig. l) arranged at and abutting against the outer side of one of the outermost plates of the row of plates has its shank 19 extending laterally through the plates and beyond the outer side of the other outermost plate of saidrow of plates, and a nut 20 is threaded onto said shank at and abuts against said side of the last-mentioned outermost plate,
and said nut is tightened against said lastciated bolts, at points-lower than the means comprising the nuts 17 and associated bolts, (see Figs. 1 and 2) by bolts 22 and nuts 23 which are applied to the plates in any approved manner-Q By the construction hereinbctore described it will be observed thatthe plates 6 are tied together under the anvil-cap; that said plates are tied together at the sides of the anvil-cap that theend portions of said plates are tied together-at a plurality of points; that-each of said plates: is interchangeable with any other of said plates,
and that by the hereinbefore described structural features and relative arrangements of'the parts the objects hereinbefore stated are successfully attained.-
lVhat I claim isr 1. In an anvil, a body-comprising a sub stantially horizontal row of substantially vertical rigid metal plates which extend transversely of said row and have the tops of their central portions forming a seat for an anvil-cap, and means for removably securing said plates together.
2. In an anvil, a body comprising a sub ing specification, 1
stantially horizontal row of substantially vertical separable rigid metal plates which extend transversely of said row and have the tops of their central portions forming a seat for an anvil-cap, said plates having said central portions clamped together under said seat at a point spaced from said seat and from the bottom edges of the plates, and means clamping the end portions of the plates together.
3. In an anvil, a body comprising a substantially horizontal row of substantially vertical rigid metal plates which extend transversely of-said row and have the tops of their central portions forming a seat for an anvil-cap, and means clamping the central portions of said plates togetherunder said seat and comprising a bolt extending through saidcentral portions of the plates, the end portions of .said plates being clamped together in proximity to the top and bottom edges-of the plates.
4:. In an anvil a body comprising a substantially horizontal row of substantially vertical plates which extend transversely of said row and arearranged close together and provided at the top of said row. with a seat for an anvil-cap, said plates being interchangeable and tied together at their end portions and under said seat.
In an anvil, abody comprising a substantially horlzontal row of substantially vertical separable metalplateswhich extend transversely of said rowand have their tops 'torming a seat fora-n anvil-cap, said plates being clamped together, and any one of said plates being interchangeable with any other of the said plates.
6. In an anvil, abody comprising asub' stantially' horizontal row of substantially vertical plateswhich extend transverselyof said .row, each plate having a recess formed at the top thereotcentrally between the ends of the plate and: extending laterally' through the plate,-the recesses in the plates being arranged in line. longitudinally of the row of plates and having bottoms forming aseat for an anvil-cap, and-the plates being secured together at their end portions and under said recesses.
