Description

Filed Aug. 16, 1927 Patented Dec. 10, 1929 UNITE FEAT-FUEL MACHINE Application filed August 16, 1927. Serial No.. 212,939.

This invention relates to peat fuel and has special reference to a novel form of machine for making same.

I have discovered that a unit of fuel in form representing a plurality of initially united hollow cylinders is an ideal form both as respects cheapness of manufacture, and efficiency and convenience in consumption, and the object of my present invention is to provide simple means for producing such units of fuel.

Other objects and advantages of the invention will appear in the further description thereof.

Referring now to the accompanying drawing, forming part of this application, and

wherein like reference characters indicate like parts:

Figure 1 is a front elevation of an improved shape of die for forming the desired fuel;

Figure 2 is a central vertical section on the line 22, Figure 1 showing in addition the outboard end of a screw feeding device to which the die is attached;

Figure 3 is a perspective view of one of the initially formed units of fuel; and

Figure 4 is a like view of the ultimate unit of fuel, being a fragmental portion of the unit shown in Figure 3.

1 represents the discharge end of a common screw or auger feeding device such. as commonly used in brick making or the like, to which is applied my improved die, and this I prefer to form in two sections 2 and 3,

the former being bolted as at t directly to the end of the auger discharge housing and the latter removably attached as by the bolts 5 to the face of the former, this being particularly for convenience in assembling or examining the interior of the die.

Recessed within the innermost shoulder of the section 2 of the die is the inverted T- shaped spider 6 for the support of the cylindrical cores 7 which extend forwardly of the end and preferably entirely through the die. There are four of these cores, one axially of the die and the other three spaced equally radially therefrom and axially of the three circular discharge orifices of the die, this being the preferred form for the results hereinafter explained. I will subsequently refer for convenience to the shape as being multiple lobe and both the receiving and discharge ends of the die are of this form, the former being in outside diameter substantially equalto the bore of the discharge end of the auger casing, and the angle of the walls of the die I have learned by experiment to give best results'if formed at an angle not to exceed 30 from the axis of the die, thus resulting in a multiple lobe die whose planes take the shape of a multiple truncated cone.

Upon the extreme outer or discharge end of the die is attached as at 8 a short sleeve or extension 9 which in cross section is the same shape and size as the discharge end of the die so that the product as formed by the latter when passing therethrough is carried horizontally for a short distance to improve the external walls of same before being final- 7 ly cut into any desired length by a common wire cutter not shown.

In Figure 3 I have shown a section or portion of the product as it comes from the machine ready for drying either artificially or 7 naturally, and as is obvious the product may be cut as desired and is in the form of three more or less delicately attached hollow cylinders which when subsequently handled are subject to fracture and found frequently separated into the form shown in Figure 4 which is the desired ultimate product.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1 A die for forming peat fuel units comprising a multiple lobe truncated cone, andv a core axially of each lobe.

2. A peat fuel die comprising a truncated cone whose'b'ore is of multiple lobe shape in cross section, and spaced cores centrally of said bore, one of said cores being axially of the cone and the others axially of the lobes.

3. A die for forming peat fuel multiple lobe units comprising a truncated cone and a cylindrical core axially of each lobe of the unit for forming a uniform thickness of lobe walls for the purpose described.

In testimony whereof I afiix my signature.
