Application 'filed August 1S, .1924. y Serial vI\To,l"i5?-2,'39.

Tol all 107mm t muy concern.'-

Be it known that I, HERBERT L. GLAZE, a lcitizen of the United States,'residing at Los Angeles, the lcounty ofLos Angeles, State of California, have invented a new and useful Fuel-Forming Die, which the followditlicult to handle in theiroriginal state, and

f when thrown into a furnace in their original,

finely dividedlstate operate to smother or ychoke the tire. To overcome this disadvantage, attempts have been made `to produce a compact fuel ffrom such cellulosic material,4

In the copending application of George C.

i Humphreys, Serial No. 697,454, filed March y 7, '1924,is described a die for the continuous production of cellulosic fuel b v'means of lwhich die it is rendered possible to take finely divided cellulosic material and, by

subjecting the same to heat and pressure,

and through a suitable extruding machine,

' this material is forced through the die, where it is continuously pressed into solid sticks which may be broken up andv used as lump or stickfuel with great advantage over the f .employment of the finely divided vcellulosic fuel. 4 y An objectof the present invention is kto provide a die by which the cellulosic material. may be more readily7 bound together to form a compact fuel when the cellulosic matcrial is subjectedlfto heat and pressure and expelledr from the 'extruding machine.

Another object of the invention is to provide a die for compressing such cellulosic material into fuel, which includes certain novel means for restricting the discharge of material from the cellulose extruding inachine, which restricting means may be readily varied to control the outlet from the machine and the resulting pressure applied upon the" cellulosic fuel.

yVarious further objects and advantages of this invention will be apparent from a description of a preferred form of fuel compressing'die embodying the invention, for

which purpose reference is made to the ac companying drawings in which the invention is shown in its preferred form.

In the drawings:

VFigure 1 isa sideelevation, mainly in longitudinal section, of the die embodying the invention. f

Fig. 2 is an end view of Figure 1.

Fig. 3 is a side elevation of the segmental choke members employed in the die, and

Fig. 4 is a sectional end view, taken on the line %4 of Figure 3.

The die shown in the ydrawing embodies a member 2 through which the cellulosic material is forced in order to compress and portion of the machine illustrateddatwl te provide a means for aligning the die therewith.` charges through a plurality of segmenta choke members 8, the details of which are more clearly shown in Figures 3 and 4. The choke members have segmental, cylindrical walls 9 'Whicln togetherdefine a varying discharge bore for the'die, and through the greaterportion oftheir length, the outer walls outwardly contract, as shown 10, the.

walls being curved frusto-conically, and thev inner end of. the'segmental choke membersn.: yareffianged outwardly, as at 11,` for a purpose hereinafter to be pointed out.

The segmental choke members 8 are held together by a wire 12 extending through openings 13 in the enlarged portion 11 of the members 8, the wire 12 having one or more breaks, as indicated at 14 so that it may contract or expand to bring the members closer or further apart to vary the cylindrical discharge port formed thereby.

The segmental choke blocks 8 are held by a head 15 against the end of the member 2, the head 15 being screvvithreaded to the member 2 as indicated at 16. 17 indicates a shoulder on the head 15 engaging the The bore 4 o-f the member 2 disv me y llO

outer .-side -of the -flanges 11 of the. inembers S'to maintain the segmental `chokemeinber S against longitudinal movement. The head 1.3 is provided at its outer end with a threaded socket 1S which receives a collar 19 having an outwardly tapering bore 2O which engages the outer tapered Walls 1() of the choke members. The collar 19 is provided with gearv teeth 21.', exteriorlyy of the socket 18, by which gear teeth the collaiMlQ is screwed into or outof the socket 18 so as to contractthe choke members Sl or permit the same to'expand, said gear 21` driven by a gear 22 mountedlon a the shaft Z3-.being support-ed inbeing shaft zo, a lng -i on the head 15 at one end, and the outer end of the shaft being supported in a bracket 25 held to the lug Q4@ by suitable means, such as screws Q6. The outer end of tlie'shaft is provided ivitli suitable control means, such as the handle 2?.

The operation of the die will nouY be describel ythe cellulosic material, `preferably heated, is fed kinto the member 2 by the extruding machine ofwhicli 3 is a aart, and caused to pass through the bore 4 thereof, Which initially forms the saine into a bar or stick of fuel. ln order to properly compress and solidify the same the outlet cf the bore 4l' is restricted by means of the segmental choke members 8, these members being brought togather a desired distance by screwing thel collar 19 into the `socket 1S through opera-y tion of the handle 27. It Willbe observed that any desired restriction of opening may be readily obtained by motion ofthe handle and this `forni `of restricting the clicking' means-permits av small force/upon the handle 27 tocause constriction of the discliargebore due to the reduced form of gearing provided by the combination of parts. rlhe restriction of the discharge bore causes the cellulosic material to be thoroughly coinpressed in the die and the material leaving the segmental choke blocks 8 is firmly bound into a bar or stick of fuel, which may bebroken or sawed int-ov desirable pieces for use in furnace, stove, orthelike.

lVhile the fuel forming die hereindescribed is Well suited for accomplishing the purposesiof this invention, it is tobc understocd vthat various modifications. may be made in details of construction Without dcparting from the spirit of the invention. This invention isof the scope set forth in the appended claims.

,f claim:-

1. A fuel forming die comprising means providing a fuel forming bore, and segmental choke members operative to restrict the discharge from the bore, ther-segmental members having tapered outer surfaces, means. engaging vthe outer surfaces shiftable relative thereto toienpand or contract the segmental members and expandible .means `mounted with the segmental,members for holding the said memberstogether.

2; A fuel 'forming die having segmental choke members .forming vthe discharge opening ofthe die, a collar engaging the choke members operative on a longitudinal motion relative thereto to expand or contr ct said segmental-choke members supported in the head, the segmental choke members vdefina ing a discharge opening for the die, a Wire 'screw the same relative to the head, thereby expanding or contracting the segmental members.
