ners of the top wall [8, lugs 36 supporting a pair
of parallel rods or rails 31 ?xed at the ends there 40
of to the tops of said lugs, and being spaced above .
said wall. Slidably mounted on the rods 31 is
a carriage 40 comprising a bottom corrugated
wall 4| and an upstanding wall 42 at oneend
of said corrugated wall. Fixed to the underside 45
of said corrugated wall 4| are pairs of sym
metrically disposed, angle-shaped members-A4,
each having a horizontal wall 44a ?xed to the
underside of said corrugated wall, and a down
wardly extending wall 45 formed, with an open; 50
ing 46 receiving therethrough one of the rods 31.

It will now be understood that the carriage
40 may be reciprocated parallel to the circular
cutter 28, whereby the food to be sliced mounted
on the carriage, may be brought past the cutter
for the slicing operation. Mounted on said car
riage is a member 50 for gripping the food on the
sliding carriage, to hold it rigid during the slicing
operation. The member 50 may be made of sheet
metal and comprises a vertical wall 5| parallel
I00, preferably having cut out portions IM to re
duce the weight thereof. Extending from the
lower end of the wall I00 is a lug I02 provided
with a screw threaded opening I03. Extending
from the upper end of the wall I00 on one side
thereof is a short arm I04 having a downwardly
extending ?at edge I05 parallel to the wall I00.
Extending from the other end of the wall I00 is a
longer arm I06 having a downwardly projecting
10 to the rods 31 and being formed with spurs-52; circular pin portion I01.
preferably cut from the metal thereof and pro
jecting toward the rotary blade. Extending from
the wall 5| at right angles thereto is a vertical
wall 53 contacting the wall 42 and having at the
upper end thereof a folded over edge, 55, form
ing a groove slidably receiving ‘the upper edge
56 of said wall 42. It will now be understood that
the member 50 may be moved in a direction
transverse to the direction of movement of the
carriage, whereby to press the food toward the
cutting blade.
~
Means is provided for adjusting the thickness
of the slices.
To this end, the wall I6 is formed
adjacent one end thereof with an arcuate slot
60. The end wall 20 is formed (as shown in
Fig. 5) with a boss SI, to which there is screwed
a vertical screw 62 having a smooth shank por
tion 63, and a head 64 at the lower end thereof.
Rotatably mounted on the shank portion 63 of
the screw 62 and supported by the head 64 is a
lever 65 having an arm 66 extending below the
wall 16, provided with a handle 61 extending
through the slot 60. The lever 65 is further pro
vided with an arm 68, at the other end of which
there is a cammed ?ange 69.
The walls I 9 and 20 of the base are formed
with bearing openings I9a and 20a, slidably re
ceiving therethrough a shaft ‘I0. Fixed to one
end ‘II of said shaft is a gauge or guide plate 12
disposed substantially parallel to the rotary blade
28 and having 'an arcuate edge ‘I3 substantially
conforming to the exposed edge of said blade.
Fixed to the plate ‘I2 is a guide pin ‘I5 extending
through an opening ‘I6 in wall 20.
Mounted on the rod ‘I0 is a plate 80 having an
opening 8| receiving said rod therethrough and
being ?xed thereto by a set screw 82. The plate
80 is provided at the bottom thereof with a hori
zontal lug 83 contacting the underside of the cam
60.
There is further mounted on the rod ‘I0 a
block 85 likewisehaving an opening 86 receiv
ing the rod therethrough and being ?xed thereto
by a set screw 81. The block 85 is formed with
a recess 90 receiving a spring pressed rounded
plunger 92 contacting the inner surface 69a. of
the cammed ?ange 69. The outer surface 69b of
said cammed ?ange contacts the member 80. It
will now be understood that the cammed flange
is received between the members 80 and 85.
GI)
Upon turning the handle 61, the lever 65 will
rotate about its axis 62 and will cause sliding
movement of the rod '10 by'reason of the engage
ment of the cam 69 between the members 80 and
85, which are ?xed to said rod.
7
The edge 60a of the wall I6 adjacent the arcu
ate slot 60 may be provided with a scale 93 to
indicate the position of the gauge plate ‘I2, and
hence to indicate the thickness of the slices. The
scale may he graduated to indicate the number
7
70 of slices per inch.
It will now be noted that a very ?ne adjust
ment may be obtained, since a swing of the lever
65through a substantial angle will move the rod
‘I0 a comparatively short distance.

H
.
The clamp I3 is provided with a vertical wall
The wall I6 of the base
of the machine is provided adjacent one end
thereof with a circular opening IIO rotatably re
ceiving the pin portion I0'I. The adjacent ledge
2 la. is formed with a depression I I I for receiving
the edge I05 of the arm I04 of the clamp.
15
Received within the screw threaded opening
I03 of the lug, I02 is a screw II3 having a ?nger
piece I I4 at the bottom end thereof, and a plate
H5 at the upper end thereof, adapted to contact
the underside of the table or support I0. It will
now be understood that upon screwing the screw
H3 against the underside of the table, the arms
I04 and I06 will be pressed against the ledge 2Ia
and wall I6 of the base, and the edge I05 and
pin I07 will be retained within the depression II I
and opening I I0 for clamping the machine ?rmly
to the support I0. The clamp may be released
by merely unscrewing the screw II3 sufficiently
to release the edge I05 from the recess III. It
will be noted that when the clamp is ?xed in 3O
position, the machine cannot rotate with respect
to the clamp.
Means is provided for sharpening the rotary
blade 28. Extending from the wall 23 of the
blade housing 22 and adjacent the top wall 25, 35
is a lug I20 having an opening I2I disposed in a
vertical plane, and an adjacent inclined opening
I22. The sharpening device I23 comprises a
curved member I25 having a handle portion I26
at one end and being provided with a pin I2'I at 40
the opposite end. At an intermediate portion
thereof the member I25 is formed with a bear
ing I28 receiving therethrough a shaft I29.
Mounted on one end' of the shaft is a grinding
wheel I30, and ?xed to the other end of the
shaft is a nut I3I.
'
-
It will be noted that when the pin I2'I is re
ceived within the opening I2 I, the grinding wheel
£30 will be disposed in a vertical plane and may
be moved by manipulating the handle portion I26
against the ?at surface 28b of the blade 28.
However, the member I25 may be lifted to re
move the pin I2'I from the opening I2I and said
pin may then be inserted within the inclined
opening I 22 to bring the wheel I 30 into an in 55
clined plane, as shown in Figs. 6 and 7 of the
drawings. By manipulating the handle I28, the
wheel I30 may then be brought against the in
clined surface 28a of the blade. With the grind—
ing wheel against the surface 280, or 281), rota 60
tion of the blade will cause a quick sharpening
of the blade. When the grinder is not in use, the
same may be entirely removed from the machine.
In Figs. 9 to 13, inclusive, there is shown a
modi?ed form of grinding implement. As shown‘ 65
in said ?gures, the housing 22a for the rotary
blade 28 is provided adjacent the top thereof
with a cut away portion I40. The top wall 25a
and the side wall 23a of said housing are cut
away to expose a portion of the blade 28 at the 70
top. The wall 23a of the housing is formed with
a lug I4I below the edge I40a formed by the cut
away portion I40. Said lug MI is formed with
a vertical through opening I42. The grinding de
vice I23a shown in Figs. 9 to 13, inclusive, may 75
3
2,119,760
be mounted on the lug Ill! in operative and in
operative positions, as willbe more clearly here
inafter explained. Said device I23a comprises a
vertical pin Hill, the bottom end of which is re
ceiv-cd withi‘ the opening 542 of the lug I4I.
Fixed to an intermediate portion of the pin I44
is a Z-shaped guard I45. The guard comp-rises
a bottom wall Iii‘; formed with an opening I41 1
receiving the pin hi4 therethrough and being
10 ?xed to said pin by a screw Hi8.
Extending up
wardly from the wall M5 is an inclined wall I50,
and extending from said inclined wall is an out
wardly extending wall I5I.
Said wall I5I sub—
stantially corresponds to the portion of the top
15 wall 25a which has been cut away.
Thus, in the
position shown in Fig. 12, with the grinding de
vice in inoperative position, the guard substan
tially covers the cut away portion I40, and hence
completes the housing 22a for covering the top
20 portion of the rotary blade 28.
Fixed to the upper end of'the pin I44 is a‘
housing I 55, preferably made of two parts I500.
and I682), screwed together by a screw IN. The
housing portion I'GBb may be formed with an
internal boss I62, on which is rotatablymounted
a circular vertical grinding wheel I63. Fixed to
the inside of the housing part I?ila is a boss “52a,
on which is rotatably mounted an inclined cir
cular grinding wheel "53a. The bottom of the
30 housing part ISIla is cut away as at IN, to re
ceive the top of the blade 28 when the grinding
device is in operative position.
In the position shown in Fig. 12, the guard I45
covers the cut away portion I 40 of the blade
housing 22a and the housing I50 is turned away
from the blade housing. In this position the
grinding device is not in use. However, the
grinding device may be moved to the position
shown in Fig. 10 by lifting said device, turning
all) the same 180 deg, and then reinserting the pin
I44 within the opening I42. In this position the
guard I45 is turned away from the blade and
the grinding wheels I53 and "5311 contact oppo
site surfaces of the portion of the blade. Rota
tion of the blade will then cause the outer edge
thereof to be ground and sharpened on both sur~
faces, which projects into housing I60 through
opening I61.
For turning the rotary blade, a flywheel I ‘H!
as shown in Fig. 14 of the drawings may be sub
stituted for the crank handle 32, said flywheel
being mounted on the shaft SI and having a
handle Ill adjacent the periphery. With this
construction a greater uniformity of speed of the
cutting blade 28 may be obtained.
It will thus be seen that there is provided a
device in which the several objects of this inven
tion are achieved, and which is well adapted to
meet the conditions of practical use.
As various possible embodiments might be
made of the above invention, and as’ various
changes might be made in the embodiments set
forth, it is to be understood that all matter here
in set forth or shown in the accompanyingdraw
ings is to be interpreted as illustrative and not
in a limiting sense. .
