1 Claim.

This invention aimsto provide a simple but efiicient machine, adapted for grinding toasted bread, crackers, nuts and the like, either domestically or commercially, for producing meal: although the machi-ne may be employed in connection with any substance which can be operated upon by it.

The invention aims to provide novel means for feeding the material which is to be divided, to provide rotary dividers of novel form, and to supply novel means for actuating the dividers. A further object of the invention is to provide, in a device of the class described, a simple but effective means where-by coarse and fine material, delivered by the machine, may be segregated.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

With the above and other objects in view,

which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it

being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings:

Fig. 1 shows, in vertical section, a device constructed in accordance with the invention, parts remaining in elevation;

Fig. 2 is a front elevation of the device depicted in Fig. 1;

Fig. 3 is a vertical section on the line 33 of Fig. 1;

Fig. 4 is a horizontal section on the line 4-4 of Fig. 1;

Fig. 5 is a longitudinal section showing a modified divider.

In carrying out the invention, there is provided a support I, in the form of a standard, equipped at its lower end with a table clamp 2, the support carrying a horizontal, cylindrical barrel 3, closed at its rear end, as shown at 4, the barrel being provided at its rear end with an upstanding neck or receiver 5.

A feeder block 6 is movable vertically in the receiver 5. A lid I is attached to the feeder block 6 and forms part thereof. The edge of the lid I forms a flange 8, which, cooperating with the upper end of the receiver 5, limits the downward movement of the feeder block 6. The lid I carries a handle 9, of any desired construction. In

the lower end of the feeder block 3 there is a concaved recess I3, struck on an arc, the center of which is coincided with the axis of a shaft II adapted to carry dividing instrumentalities hereinafter referred to.

A bearing member I4, in the form of a bar, is located at the forward end of the barrel 3 and abuts thereagainst, the bearing bar being provided at its ends with rearwardly extended fingers I5, carrying holding means, such as set screws I6, adapted to engage the barrel 3 and to hold the bearing member I4 in place removably.

The bearing member I4 is supplied intermediate its ends with an opening I! wherein is received a reduced tip I8 on the forward end of the shaft I I, hereinbefore mentioned.

The shaft I I is supported for rotation, not only in the bearing member I4, but in the rear end wall 4 of the barrel 3. At its rear end, the shaft I I is supplied with a polygonal foot I9, on which is fitted the socket 20 of a hand crank 2|. A screw 22 in the rear end of the socket 20, engages the end of the shaft II, and holds the crank 2| in place.

A cylindrical divider 23 is located in the barrel 3 and may be of various constructions. As shown in Fig. 4, knives 24 are struck outwardly from the body of the divider, to define openings 25. The knives 24 move in close relation to the inner surface of the barrel 3, and there is a space between the outer surface of the divider and the inner surface of the barrel, the space being designated by the numeral 26. The divider 23 has a rear end wall 21, abutting against the rear end wall 4 of the barrel 3, the shaft II being secured in the rear end wall 21. A cruciform bracket 28 is secured to the shaft I I, about midway between the ends thereof, the outer ends of the arms of the bracket engaging the divider 23, to strengthen its mounting on the shaft I I. In connection with some forms of dividers, the bracket 28 may be omitted.

The material to be divided is placed in the receiver 5, within the concaved recess II] at the lower end of the feed block 6, and the feed block is thrust down. In this way, the material to be divided is kept in close and intimate contact with the divider 23. When the material in the receiver 5 has been used up, the flange 8 of the feeder block 6 comes into contact with the upper end of the receiver 5, and the lower end of the feeder block does not come into contact with the divider.

The material which is being divided moves forwardly. Some portions of the divided material will be in the space shown at 26 in Fig. 1, and some portions of the material will be located inside th divider 23. The finer material passes through the openings 25 of Fig. 4, into the divider 23, and this finer material is discharged at the forward end of the machine, through the open, forward end of the divider. The coarser material remains in the space 26, and is segregated from the finer material, because the barrel 3 is provided near its discharge end with a depending spout 29, shown in Fig. l, the coarser material passing downwardly through the spout.

In Fig. 5, parts hereinbefore described have been designated by numerals already used, with the sufiix a. The divider 23a replaces the divider 23 when meal is to be turned out. The parts 24a, instead of being knives, as shown in Fig. 4, are outstanding burrs, adapted for the specific purpose in view.

Although the machine has been shown as being operated through the instrumentality of a hand crank 2 I, no illustration is required to support the statement that the shaft may be power operated if desired.

The machine hereinbefore described is simple in construction, but it will be found thoroughly advantageous for the ends in View, and capable of consummating the objects set forth in the opening portion of this specification.

Having thus described the invention, what is claimed is:

In a food grinder, a support, a substantially horizontal cylindrical barrel carried by the support and open at its forward end, the barrel having a rear end wall and being provided with an upstanding receiver having a rear wall in vertical alignment with the rear end wall of the barrel, a depending spout carried by the barrel and communicating with the barrel, and a cylindrical tubular divider supported coaxially in the barrel,

for rotation therein, and extended forwardly above the spout, to a place closely adjacent to the open end of the barrel, there being a space for coarsely divided material between the divider and the barrel, the divider having an open forward end, and having openings defining dividing ele ments distributed throughout the entire length of the divider and extended outwardly into close relation to the barrel; the spout being of small cross section and being disposed close to the forward end of the barrel and the barrel and the divider being extended well beyond the forward wall of the receiver whereby the dividing elements will have opportunity to work on coarsely divided material before it reaches the spout.
