An Improved Crumb Remover.
I, JAMES BENJAMIN ORIC SHEVILL, of 118, Quincy Street, Brooklyn,
New York, Importer, do hereby declare the nature of this invention to be as
follows:-
My invention is an improvement in that class of crumb removers for table use
which are provided with a revoluble brush arranged in front of a crumb receiving
pocket or compartment. My device comprises a longitudinal slotted casing which
encloses the brush together with its operating gearing, and a handle which is
pivoted to the top of the casing and arranged in alignment with it, and so
constructed as to provide stops that limit the vertical movement or oscillation of
the handle relative to the casing.
The improved casing is approximately semi-circular in cross-section, and is
closed in at the ends and provided with partitions to form compartments for the
mechanism, the partitions being connected to the ends and connected to each
other. A door is hinged to the rear edge of the bottom plate which connects the
partitions, to permit of the removal of the crumbs gathered in a pocket in the
casing by the brush, said door being furnished with a suitable catch for securing it
in position. The driving mechanism consists of internal toothed wheels meshing
with pinions secured to the outer ends of the shaft on which the brush is mounted,
the wheels being journalled on studs supported in the partition in which the shaft
is also mounted. The drive wheels project beyond the surface of the bottom
plate of the casing so as to hold the casing above the table-cloth, and their
peripheries are preferably covered by a rubber band. By forming the opening in
the casing in front of the lower part of the brush, and by cutting away part of
the lower front edge of the casing and part of the bottom, the brush, as it is
moved over the cloth, sweeps up the crumbs over a curved bottom plate into a
pocket in rear of the latter, any crumbs adhering to the brush being removed by a
scraper attached to the top of the casing.
same.
The handle is pivoted to the top of the casing in alignment with it and projects
beyond one of its ends so that it may be conveniently grasped and the inner end
of its shank is slightly curved and pivoted between lugs that project from a plate
attached to the top of the casing at a point equidistant from the ends of the
The pivotal point is slightly removed from the end of the shauk and also
from the plate so as to provide a narrow space between the latter and the shank.
Thus the vertical movement or oscillation of the handle relative to the casing is
limited by contact of the shank with said plate at a point on each side of the
pivot, and the upward movement of the handle is limited by contact of its free
end with said plate and its downward movement is limited by contact of the body
of the shank with said plate on the inner side of the pivot. Practically, therefore,
the movement of the handle and casing relative to each other is limited by stops
arranged adjacent to the pivot of the former.

1 JAMES BENJAMIN ORIC SHEVILL, of 118 Quincy Street, Brooklyn, in
the County of Kings and State of New York, United States of America,
Importer 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:-
My invention is an improvement in that class of crumb removers for table use
which are provided with a revoluble brush arranged in front of a crumb receptacle
or compartment. My device comprises a longitudinal slotted casing which encloses
the brush together with its operating gearing and a handle which is pivoted to the
top of the casing and arranged in alignment with it and so constructed as to
provide stops that limit the vertical movement or oscillation of the handle relative
to the casing, as hereinafter fully set forth.
Reference is to be had to the accompanying drawings forming a part of this
Specification, in which similar letters of reference indicate corresponding parts iu
all the figures.
Figure 1 is a perspective view of the improvement;
Figure 2 is a rear side elevation of the same;
Figure 3 is a sectional side elevation of the same;
Figure 4 is a cross section of the same on the line 4-4 of Figure 2;
Figure 5 is an inverted plan view of the same; and
Figure 6 is a transverse section of the same on the line 6-6 of Figure 2.
The improved crumb remover is provided with a casing A, made approximately
semi-circular in cross section, as indicated in Figure 4, the casing having the
ends A', A and transverse partitions A³, A* arranged near the said ends A, A²,
respectively, so as to form compartments therewith for the driving mechanism of
the remover. The partitions A³, A' are connected to the ends A', A² at their
bottom parts by the plates A³, as plainly indicated in Figure 5, and the said
partitions are rigidly connected with each other at their ends and at their bottom
edges by the bottom plate A, see Figure 5. On the rear edge of the latter is
hinged at A a door As provided with a suitable catch A' for locking the said door
to the rear end of the casing, and permitting opening of the said door to remove
the crumbs gathered by the brush, as hereinafter more fully described.
In the spaces between the partitions A³, A* and the ends A¹ A² of the casing A
are arranged driving wheels B, preferably covered at their peripheries by a rubber
baud which extends upon the rim of the wheels and below the surface of the
bottom plate A, to support the casing above the table cloth, over which the
remover is moved to gather up the crumbs.
The wheels B are journaled on studs C, supported in the partitions A³, A', and
each of the wheels B is formed with an internal gear B' in mesh with a pinion D,
secured on the respective outer end of the shaft E of the revoluble brush F, said
shaft E being journaled in the partitions A A+. The brush F has its bristles
preferably set spirally on the hub of the brush, as is plainly illustrated in
Figures 3 and 5, but I do not limit myself to this special construction of the
revoluble brush.
By forming the opening in the casing in front of the lower part of the brush,
and by cutting away part of the lower front edge of the casing and part of the
bottom, the said revoluble brush as it is moved over the table cloth, sweeps up and
removes the crumbs in the path of the casing. By the arrangements described no
additional trailing or supporting wheels are required.

page_text: The brush sweeps the crumbs upward over the curved plate G (Fig. 4) into a
receptacle in rear of the latter, and any crumbs adhering to the brush are removed
by the scraper H, attached to the top of the casing A.
The attachment and arrangement of the handle J, are as follows:
The handle is pivoted to the top of the casing in alignment with it, and projects
beyond one of its ends, so that it may be conveniently grasped for the purpose of
manipulating the crumb remover proper.
The inner end J¹ of the shank J is slightly curved and pivoted between lugs I'
that project from a plate I, attached to the top of the casing at a point equidistant
from the ends of the same.
The pivotal point is slightly removed from the end of the shank J¹ and also
from the plate I, so as to provide a narrow space between the latter and the shank.
It is apparent that by this construction and arrangement the vertical movement or
oscillation of the handle J, relative to the casing A, is limited by contact of the
shank with said plate I, at a point on each side of the pivot; thus the upward
movement of the handle J, is limited by contact of its free end with said plate,
as shown by dotted lines Figure 2, while its downward movement is limited by
contact of the body of the shank with said plate, on the inner side of the pivot, as
shown by full lines, Figure 2.
Practically, therefore, the movement of the handle and casing relative to each
other is limited by stops arranged adjacent to the pivot of the former.
The crumb remover may be swept over a table like the hand brush commonly
used without any difficulty in keeping the casing and brush in contact with the
cloth or other surface, and when the device is lifted from the table it may be held
and carried horizontally, that is to say, without danger of tilting vertically which
would permit dislodgement and escape of at least some portion of the contents of
the crumb receptacle.
".
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 crumb remover, comprising a casing having an opening in its bottom and
provided with a compartment at each end and with a receptacle at the rear, drive
wheels mounted in the compartments, a brush mounted in the casing and gearing
for operating the brush from the said wheels, substantially as described.
2. A crumb remover, comprising a casing having an opening in its bottom and
provided with end compartments and a crumb receptacle having a door, drive
wheels mounted in the end compartiments, said drive wheels having elastic
peripheries and formed with internal gears, a brush mounted in the casing and
having its shaft projecting into the end compartments, gear wheels on the brush
shaft in the end compartments and meshing with the gears of the drive wheel, and
a scraper depending from the top of the casing, and a handle pivoted on the top of
the casing, substantially as herein shown and described.
