1 Claim.
(Cl. 146-215)
My invention relates to butcher blocks, of the
kind generally used in butcher shops, and upon
which blocks the meat-cutting, chopping, sawing,
etc., is done, and has among its objects the pro
5 duction of such a block that will be simple in
construction, neat in appearance, sanitary, eco
nomical, and otherwise satisfactory and efficient
for use wherever deemed applicable.
The common type of butcher block wears down
10 more or less rapidly, dependent upon the amount
of work done thereon and the skill and care with
which the same is performed, and the usual prac
tice has been to saw, chop or otherwise dress the
resultant uneven working surface down to a new
15 level surface, and it is apparent that after a cer
tain number of such re-surfacings the block is too
low for safe or economical meat-cutting opera
tions thereon, and hence must be discarded al
together. These re-surfacing operations, and the
?nal discarding of the block, are relatively ex
pensive, and in those cases where the discarding
is deferred too long the loss in ef?ciency of work
ing on such blocks is great.
My invention has among its objects the pro
duction of a block of the kind described, wherein
the effective working surface, upon which the
cutting and chopping operations are performed
by the butcher, does not extend the full height
or thickness of the block, but for only a minor
fraction of such thickness, and hence this rela
tively expensive portion not only reduces the
initial cost of the block, but permits of replace
ments from time to time at a minimum of ex
Another object of my invention is to provide
a butcher block having a working surface that
may be replaced quickly, easily, and at a mini
mum of expense, and wherein the working height
of the block can be substantially maintained in
40 de?nitely.
A further object of the invention is to provide
such a block wherein not only the height, but
the weight and work surface dimensions may be
retained ?xed for the full life or use of the block,
and hence wherein the value of the block will
remain substantially constant insofar as utility
and efficiency is concerned.
A still further object of the invention is to pro
vide a replacement top for a cutting block, of
either the same or a different sized working area,
as preferred, at a reduced cost.
An added object of my invention is to provide
a replaceable work top for a block, the same to
be held in place by substantially its own weight
55 and without the use of tension bolts or the like,
and which may be lifted from its assembled posi
tion through jack means operable from beneath
the base of the block.
Other objects of the invention are to provide
a block construction of the kind described, where Ol
in the force of the cutting or chopping will be
suitably absorbed through the same, without un
due noise, or other objectionable features.
Many other objects of the construction shown,
and the method of performing the same, will be 10
obvious to‘ those skilled in the art to which this
invention appertains, from the disclosures herein
To this end, my invention consists in the novel
construction, arrangement and combination of
parts herein shown and described, and the meth
od of forming the block, as will be more particu
larly pointed out in the claim.
In the drawing, wherein like reference char
acters indicate like or corresponding parts 20
throughout the views,
Figure 1 illustrates an old block about ready
for discarding; and
Figure 2 is a cross-sectional view through a
re-built block according to my invention.
Referring more particularly to the drawing,
wherein I have illustrated one of the preferred
embodiments of my invention, there is shown an
old meat-chopping or butcher block, shown ap
proximately rectangular in working surface for 30
the sake of convenience and because most of the
blocks now in use are of that design, the main body
or base portion i being of suitable wood, such as
maple for example, and built up of a number of
layers or laminations having through bolts 2 or
the like for holding them tightly together to
prevent warping or otherwise become shifted
from their predetermined relationship. These
laminations are usually arranged on end, so that
the uppermost or work surface is cut across the 40
grain, of the wood, for well known reasons. The
legs 3 are secured to the block body to raise the
block to the desired working height.
As these blocks become worn they are sawed,
cut, or otherwise worked on to present a new 45
plane or level working surface, but it is apparent
that after a time it is impractical to cut more
material from the top because it is too close to
the through bolts 2. Further, by that time, the
height of the block will be such that it is no
longer safe or e?icient to use, because not only
will there be danger to the tools and operator
when working at such a low table, but the work
performed under these conditions is very unsatis
factory in quality and cost. Heretofore, the only
thing that could be done was to discard the old
block and obtain a new one.
The new ones, on
The thickness of the work slab is such that it
may be dressed down once or twice if so desired,
the other hand, were made purposely higher than
and then replaced with an entirely new slab, or
needed or desired, so as to provide for a maxi
thus replaced without any dressing whatsoever,
mum number of re-dressing operations, and hence
the new blocks were not truly efficient until after
a few re-dressings.
In my improved construction, in the construc
tion shown, I prefer to use the old block as a
10 foundation from which the new block is formed,
the top surface of the old block being ?rst leveled
as shown in Fig. 2. Upon the old block is posi
tioned a slab member ll of relatively heavy thick
ness, and preferably of wood, but not necessarily
15 laminated, and thereby the cost of the same is
relatively inexpensive. Superimposed on this
?ller slab is the work slab member 5, the latter
being of high-grade material and construction,
so as to withstand the usage to which it is to be
20 put, and hence may be made of a good grade of
maple or the like, the sections or laminations
standing on end, and with their uppermost ends
cut across the grain of the wood. The thickness
of this slab 5 may be less than that of the slab 4.
The ?ller slab 4 may be prevented against lat
eral shifting relatively of the base or main block
I, by dowels 6 placed therebetween, and the work
slab 5 may be similarly prevented against lateral
displacement by means of dowels l.
A band or
30 tie 8 may be secured about the sections of the
top plate 5 to clamp them together into a unitary
element, this band being preferably of metal.
Although the slabs G and 5 are relatively heavy,
so as to be able to withstand the service to
which they are subjected, yet for the purpose of
giving additional weight, and of still better hold
ing said slabs in place, I have provided an apron
member having an inwardly directed substantial
ly horizontal flange 9 resting on the top surface
of the base element, about the periphery of the
latter, said apron member having another por
tion directed downwardly therefrom at 10 and
an oppositely directed portion ii. The portion
in snugly encircles the peripheral surface of the
base member l, while the other portion ll simi
larly encircles the peripheral surface of the ?ller
slab and substantially half of that of the work
slab. The ?ller slab is provided with a cut-out
or shoulder it on its under side and along its
periphery to receive the flange 9, while the upper
edge of the portion ll may be provided with a
cut-out or shoulder it‘ to receive the band 8.
The use of the apron member of the size shown
will permit of the use of a top slab of larger effec
55 tive working area than the top of the original
block I, and hence this excess working area is
obtainable at substantially no increased cost.
inasmuch as the costs of such replacements are 5
relatively low. Thus, the original height of the
block as shown in Fig. 2 may be retained for in
de?nite periods, so that the maximum safety and
operating ei?ciency of the block may be preserved.
In order to conveniently displace the work slab, 10
for dressing or replacement, I have provided a
simple jack means l4 therefor, the same extend
ing centrally through the base or body portion I
and having an enlarged top or head l5 ?tting
within an opening [6 on the under side of the 15
?ller slab. As the jack is operated, as by a socket
wrench or the like, from beneath the block, the
pair of slabs will be lifted in unison to the desired
height, the dowels acting as guides during this
vertical movement, after which the top slab may 20
be handled as desired.
Obviously, by the construction hereinbefore
shown and described, the resultant block will be
such that the height can be retained inde?nitely,
and wherein all of the parts except the relatively 25
thin work top will retain the ?xed height, weight
dimensions and value, as there is no destruction
due to wear, except the small amount at the work
top and which can be corrected by replacements
at small cost.
Having thus described my invention, it is obvi
ous that various immaterial modi?cations may
be made in the same without departing from the
spirit of my invention; hence I do not wish to
be understood as limiting myself to the exact 35
form, arrangement, combination and construc
tion, or the method used, except as limited by the
state of the art to which this invention apper
tains or the claim hereunto appended.
What I claim as new and desire to secure by 40
Letters Patent is:
The combination with a butcher block provided
with a top surface, of a detachable top member
therefor comprising independently movable up
per and lower layers freely supported as a unit 45
on said block, a ?ange peripherally about the
top of said block and projecting above and below
thereat, said top member being received as a unit
within said ?ange so as to project thereabove and
being vertically movable as a unit past the top 50
of said ?ange while the latter remains in place
on the block, and means operable from beneath
said block free of securement with said upper
and lower layers of said top to lift said top as
a unit.
