Specification of Letters Patent.

Patented Dec. 12, 1905.

Application filed February 16, 1905. Serial No. 245,889.

1'0 a/Z w/wm t may concern:

Be it known that I, JAMES M. DENNIS, a citizen of the United States, and a resident of the city of Richmond, in the county of Wayne and State of Indiana, (whose postoffice address is Richmond, In'diana,) have invented certain new and useful Improvements in Artificial-Fuel Forming and Oompressino Machines, of which the following is a specication, which when taken in connection with the accompanying drawings, forming a part thereof, is sufliciently clear and concise as to enable others skilled in the art form, which will be strong and durable in construction, positive in action, compact and symmetrical in proportions, and capable of a wide scope of usefulness and efhciency.

Another object is the provision of an artificial-fuel forming and compressing machine composed of interdependent and cooperating elements Vso arranged and combined as to produce fuel units of the desired and predetermined density and at the same time performing the work rapidly and at a very low cost of production.

A still further object is to provide an artificial-fuel forming and compressing machine which involves simplicity of construction and operation, in which the greatest possible efficiency or working power is secured with a minimum of power and manual energy applied thereto, and whereby the attendant will be enabled to control its operations so that its work may be changed or variated when desired and in which the work will be performed with certainty and precision.

Another object of my invention is to provide a machine having very powerful compression and resistance qualities in order that the material being operated upon thereby will be formed into units of great solidity and density for the purposes both of influencing the combustion'qualities of the fuel and also view of the machine.

to admit of the finished product being handlednvithout danger of crumbling and with economy in transportation, and, finally, another obj ect is to produce an economicallyoperative machine which will produce fuel units from disintegrated and conditioned materiall of a superior and uniform density which will retain their form without liability of cracking or of being fractured either by handling or by the action of climatic conditions, which machine will be complete and simple both in construction and operation.

Other objects and specific advantages of this invention will be made manifest in the course of the following specification.

It should be noticed that the machine covered by this present patent may-be used with slight modifications for operating on a great variety of materials and substances; but primarily it is designed for the manufacture of artificial fuel briquets, blocks, lumps, or other forms of units, and a particular instance illustrating the material operated on and for which this machine is especially adapted will be found described in Letters Patent No. 773,004, dated October 25, 1904. In carrying out the general objects above referred to by the mechanical construction and arrangement constituting the .present invention I have arranged the various parts and devices and the essential elements in approXimately-that is, substantially-pro gressive succession-that is to say, whereby one of the essential steps in the process stated in the patent above referred to is accomplished in its order-that is, the compression and formation of the product into fuel units.

One manner of carrying out the obj ects of my invention and that which in practice has been found most desirable is illustrated in the accompanying drawings, in which- Figure l is a front elevation of my invention. Fig. 2 is a rear elevation of my invention. Fig. 3 is a left-hand end view of the said parts. Fig. 41E-is a right-hand elevation of the end of my invention. Fig. 5 is a plan Figs. 6 and 7" are detail views of the knockers for removing the product from the compressionchambers. Fig. 8 is a detail view of the force-feed for the machine. Fig. 9 is a horizontal longitudinal section of the machine', taken through the IOO machine on the line :z: of Fig. l2. Fig. 10 shows a vertical longitudinal section taken through the machine on the line Y Y of Fig. 5. Fig. 11 is a side elevation of one of the compressed and completed fuel units. Fig. 12 is an end elevation of one of the compressed and completed fuel units, and Figs. 13 and 14 are detail views of antifrictionbearings for closing the ends of the compression-chambers.

Similar indices refer to and denote like parts throughout the several views of the drawings.

With all of the above-designated views in mind I will now take up the description of the invention in concrete detail and will refer to the various parts as briefly and compactly as I may.

My machine has incorporated therein as the basis thereof the main frame or pedestal A, which is shown in side elevation in Figs. 1 and 2 and in end elevation in Figs. 3 and 4. The said frame is provided with the four base feet a a a a for contact with the floor and with means whereby the machine may be secured to the floor or to a foundation. 'Ihe top or upper edge of the said frame terminates in a flange forming the horizontal bedplate a, which should have a perfectlyT level upper face which extends entirely around the central hollow portion or well of the main frame.

Mounted on the bed-plate d, central of the left-hand portion thereof, are the two corresponding and oppositely-disposed ournalboxings B and C, permanently located on the front and the rear, respectively. Mounted in the said journal-boxings B and C is the comparatively heavy axle D, which axle is provided with a central channel .fl therethrough extending from end to end thereof in an axial direction, as shown. Mounted on the axle D, between the sides of the main frame, is the compressor-wheel E, which is provided with a hub e, the terminals of which are adapted to contact with the journal-boxings B and C, by which end movement or thrust of the compressor-wheel E is prevented.

The interior of the compressor-wheel E is formed hollow to provide an annular steamspace whereby it may be heated, which will be fully explained hereinafter. The rim portion of the compressor-wheel E is of less thickness 'than is the hollow steam-space portion, and in the periphery of the rim are formed a multitude of U-shaped cavities or compression-chambers, as indicated by the numeral 1, which chambers extend entirely through the rim in an axial di rection-that is, at right angles to the face of the wheel. The ends of said compression-chambers are adapted to be closed when a compression takes place by means of a frictionless mechanism, which will hereinafter be fully explained and pointed out. Each of said compressionchambers is entirely separated from all of the others by facets, each of which facets is formed of a portion of the natural peripheral curvature of the periphery of the rim of the wheel, said facets being designated by the indice at, and the size of each facet is slightly less than are the mouths of the said compression-chambers. The formation of said compression-chambers and facets is clearly shown in Fig. 10. Mounted on the front end portion of the axle D outside the frame A arev the two pulleys 1 0 and 11, the purposes of which will presently appear. Mounted on the rear end portion of the axle D is the gear 12, by which the axle D and the wheel E may be revolved, as will presently be fully explained.

Integral with and rising from the bedplate near its right-hand end are the two oppositely-disposed lugs 3 and 3. Mounted slidably on top ofthe bed-plate, central of the right-hand portion thereof, are the two corresponding and oppositely-disposed ournal-boxings F and G, located on the front and rear portions, respectively. Mounted in the journal-bearings F and G is the comparatively heavy axle II, similar to but of less length than the said axle D, which axle H is provided with a central channel 7L, extending through from end to end thereof in an axial direction. Mounted on the axle H between the sides of the main frame is the compressorwheel I, which is provided with a hub i, the terminals of which are adapted to contact with the journal-boxings F and G, by which end movement or thrust of the compressionwheel I is prevented. The interior of the compressor-wheel I is formed hollow to provide an annular steam-space whereby it may be heated, which will be fully explained hereinafter. The rim portion of the compressor-wheel I is of less thickness than is the hollow steam-space portion, and in the periphery of the rim are formed a multitude of U-shaped cavities or compression-chambers, as indicated by the numeral 2, which chambers extend entirely through the rim in an axial direction-that is, at right angles to the face of the wheel. The ends of said compression-chambers are adapted to be closed when a compression takes place by means of a frictionless mechanism, which will hereinafter be fully explained and pointed out. Each of said compression-chambers is entirely separated from all of the others by facets, each of which consists of a portion of the natural peripheral curvature of the periphery of the rim of the Wheel, said facets being denoted by the indices z, and the size of` each facet is slightly less than are the mouths of said compression-chambers. The formation of said compression-chambers and facets is clearly shown in Fig. 10;

It will have been noticed that the compressor-wheels E and I are essentially and IOS ITO

IZO

identically alike in size and construction, and they are mounted revolubly together with an approximately iifty-per-cent. fluxionary mesh-that is to say, the facets :r of the wheel E enter the cavities 2 of the wheel I.

Likewise the facets. z of the wheel I entery the cavities of the wheel E, as is clearly indicated in Fig. 10.

As before stated, the ournal-boxinvs F and G are mounted slidable on the bed-plate. This sliding movement is prevented from extending too far to the left by the following described means: The numerals 13 and 13 denote lugs integral with and extending up from the face of the bed-plate, as shown. Through each of said lugs is a horizontallydisposed adjusting- screw 14 and 14, respectively, whose points are contactible with the respective journal-boxings F and G, whereby the wheel I may be given a limit of approach to its consort the wheel E. The lateral movement of the wheel I to the right is prevented from extending too far by means of a flexible adjustment, which is described as follows: Threaded horizontally into the lugs 3 and 3' are the relatively long adjustingscrews 15 and 15', respectively, with their screw ends directed toward the journal-bearings F and G. Pivoted on the ends of the screws 15 and 15' are the bosses 16 and 16', respectively, each having a short inwardlyprojecting stem adapted to enter a short distance into its respective helical compressionsprings 17 and 17', respectively. Said springs are seated against the shoulders of the journal-bearings F and G and against the shoulders of the bosses 16 and 16', respectively, as shown.

The numeral 18 denotes a shaft, one end being ournaled in a bearing therefor on the rear side of the frame A, the other end being journaled in the double-pedestal hanger 19.

Mounted on the shaft 18is the pinion 20, which meshes with the gear 12, and also mounted on the shaft 18 is the gear 21.

The numeral 22 denotes a shaft, one end being journaled in a bearing therefor on the rear side of the frame A, the other end being journaled in the double-pedestal hanger 19. Mounted on the shaft 22 is the pinion 23, which meshes with the gear 21., and also mounted on the shaft 22 is the gear 24.

The numeral 25 denotes the driving-shaft, 011e end thereof being j ournaled in the bearing therefor on the rear side of the base A, the other end being journal'edin the singlepedestal hanger 26. Mounted on the drivingshaft 25 is a pinion 27, meshing with the gear 24.

It will now be apparent that the shaft'25 may be driven at a high rate of speed by means of suitable pulleysor the like secured thereon, which operate the various drive and driven gears and pinions and will result in the compression-wheels being operated comparatively slow, but withal at great power and positiveness. f

Secured on the center of the bedplate and projecting inwardly and upwardly and almost contacting with the sides of the rims of the wheels E and I, across the meeting portions of which they extend, are the front and rear housing- plates 28 and 29, respectively, by which the contacting and intermeshing portions of the compression-wheels are incased, substantially as indicated in the drawings. The ends of the meeting compressionchambers are retained tightly closed during compression by means of the antifrictiondisks 75 and 76,v which are loosely fitted in corresponding cavities therefor formed in the inner faces of the respective housingplates 28 and 29. `"As will be noticed, disks are located to the right (to the left, if desired) of the center in order that greater traction will be exerted on one side than on the other, whereby they may be revolved rather than counterbalanced, which would be the result if they were located centrally. The said disks 75 and 76 rest on a bank of balls which cover the bottom of the said cavities, and they bring the faces of the disks tightly in contact with the sides of the rim of the compression-wheels, and each system of said balls is denoted in the drawings by the numerals 77 and 78, front and rear, respectively.

By the above it will be apparent that the meeting compression-Chambers of the two wheels E and I will at all times have their ends tightly andsecurely closed bysaid disks, whereby as the pressure is exerted upon the material to compress it there will be none of it lost through the ends of the compressionchambers.

The tops of the housing-plates 2 8 and 29 do not extend to the height of the compression-wheels, and on top said plates are secured together, and rising therefrom is the double-wall supply-spout 30, which spout may extend to a floor above or to other points to conduct the material to the machine to be operated on.

In the process of forming and compressing the fuel the material of which it is composed is preferably previously prepared in a finelypowdered condition, and it is usually delivered to the machine in a heated state.

In order that the material may not cool in the operation of compression and in order to obtain the proper results as to compression and cohesion, it is highly material that the compression-wheels should be heated, and I have found that steam-heating gives the most satisfactory results, although hot air or hot water might be employed with discretionary aptitude.

The steam-heating system of the machine is describable as follows: A n essential part of this system is the interior spaces of the IOO compression-wheels and of the said apertures d and h, formed through the respective axles D and H. Communication is established between the interior of the compressionwheels and the said apertures of the axles, respectively, by means of the crosseapertures d d in the axle D and the cross-apertures h h in the axle H, which apertures are formed through the center of the respective axles at right angles to the axial direction and to the apertures (Z and h, respectively, as is indicated, and whereby communication is established between the interior spaces of the compression wheels and the central axial apertures of the axles. Secured in and extending out from the rear end of the aperture d is a nipple 31, having on its outer end one member of the flexible coupling 32, the other member of said coupling having the short pipe 33, extending out therefrom, and on the outer end of the latter is secured the T-fitting 34. Entering the fitting 34 is the live-steam supply-pipe 35. Secured in and extending out from the rear end of the aperture h is a nipple 36, having on its outer end one member of the flexible coupling 37, the other member of said coupling having the pipe 38 extending out therefrom, (on a line with the outer end of the pipe 33,) and on the outer end of the latter is secured the L-fitting 39. Connecting the fittings and 39 is the pipe 40. Thus it will be seen that by the above means are provided for furnishing live steam to the compression-wheels. Secured in and extending out from the front end of the aperture d is a nipple 41, having on its outer end one member of the flexible coupling 42, the other member of said coupling having the nipple 43 extending out therefrom, and on the outer end of the latter is se* cured the three-way fitting 44, which latter has the exhaust-pipe 35 extending down therefrom to the point desired for the exhaust. Secured in and extending out from the front end of the aperture 7L is a nipple 46, having on its outer end one member of the flexible coupling 47, the other member of said coupling having the pipe 48 extending out therefrom, and on the outer end of the latter is secured the L-fitting 49. The littings 44 and 49 are connected by the pipe 50. Thus it will be seen that by the above means are provided for exhausting the steam from the compression-wheels.. By means of the above-described steamheating system means are provided for passing a continuous flow of live steam or the like through the compression-wheels.

The lower end of the sup ply-spout 30 opens into the mouth of the hopper-space formed by the housingplates 28 and 29 and the peripheries of the compression-wheels, as shown in Figs. 9 and 10, and mounted centrally across through the lower portion of the supply-spout 30 is a small shaft 51, which prosoav jects a considerable distance forward, with a pulley 52 mounted on its forward end on a line with the said pulley 11, and the pulleys 52 and 11 are connected by a belt 53, whereby the shaft 51 is revolubly mounted to rotate with the axle D. Mounted directly under and at right angles to the shaft 51 and central of the spout 31 is the screw force feed 54, which is mounted in a spider carried in the lower end portion of the spout 30. On the upper end of the screw-feed shaft is a bevel gear-wheel 55, which meshes with a similar bevel gear-wheel 56, which latter is secured on the shaft 51. The gear-wheels 55 and 56 maybe covered by ahood, (not shown,) if found advisable, in order to protect said gear-wheels. By the above-described arrangement it is apparent that l have provided a force feed for the material which will be practical and efficient. 1

The lower peripheral portion of each of the compression-wheels E and I are provided with knockers M and N, respectively, which are of identical construction and are shown in detail in Figs. 6 and 7. Said knockers consist, essentially, of spring body portion to be bolted at one end to the inside wall of the interior of the well of the main frame, as shown in Figs. 5, 9, and lO, and each having a roller M and N, respectively, which are adapted to press with considerable force the sides of the rims of the compression-wheels and to enter slightly into each of the compression-charm bers l and 2, respectively, as the compression-wheels revolve.

Mounted in the lower end portion of the main frame A are the horizontal shafts 57 on the left and 58 on the right. Mounted on the shafts 57 and 58 central of the main frame are the relatively wide-faced pulleys 59 and 60, respectively, over which and between which pulleys extends the screen conveyer-belt 61. The shaft 57 extends out beyond the frame A, and on its outer portion is mounted the pulley 62. Connecting the pulleys 62 and l0 is the belt 63, by which the conveyer-belt is caused to move endwise to convey the finished product to one end of the machine or to some other point, and by means of the open-work or screen the fine particles of dust or the like are allowed to fall through to the floor or to a receptacle for that purpose, which may be deposited below the conveyer.

Numeral 64 denotes a double or two-part bracket mounted on the bed-plate at the left end of the main frame, which bracket carries a small shaft 65, on which is mounted the lubricator 66, having spurs around on its periphery to fit into and mesh in the compression chambersV l, the lubricator 66 being adapted to expurgate and lubricate the compression-chambers 1 and the facets x, and also mounted on the bed-plate, below said lubricator 66, is the lubricant-receptacle 67,

the lubricator 70, having spurs around on its periphery to lfit into and mesh in the compressionechambers 2, the lubricator 70 being adapted to expurgate and lubricate the compression-chambers 2 and the facets e, and mounted on the bed-plate, below the said lubricator 70, is the lubricant-receptacle 7l,`

throughwhich the lower segmental portion of the lubricator moves and from which the A lubricant is transmitted to the said compresthen allowed to exhaust through the pipe 45.

sion-chambers and to said facets.

The steam-space of the compressor-wheels E and I being of comparatively large dimension, I consider it at least prudent to connect the walls of said chambers by a number of strut stay-bolts S and 5, respectively, in order to guard against a possible plenum or vacuum therein.

Means for draining the interiors of the compressor-wheels E and I is provided by the apertures U and V, respectively, which apertures are ordinarily closed by a screw-plug.

The absolute essential of this machine, a

will have been surmised, is the two identical compressor-wheels E and I, which are i of novel design both as to their interior and exterior construction, and particularly as to the compression-chambers in their peripheries, the manner of their intermeshing, and the novel manner -for closing the ends of the compression-chambers, and I desire it understood that my attempts to apply the various principles involved have been highly satisfactory.

Operation: The operation of the machine is substantially as follows: The power being applied to operate the shaft 25 from right to left, the power will be transmitted through the intermediate gears above shown and described. The operation of the compressorwheels will be in the direction of the arrows, as shown in Figs. l and 10. The steam being admitted through the pipe 35`is admitted to the interiors of the compressor-wheels and The admission and exhaust o the steam is controlled by suitable valves, which are not a part of this invention. The machine being otherwise in readiness, the previously prepared and heated material is allowed to enter through the spout 30 and is fed to the machine by the force feed, the material being interjected between the approaching faces of the compressor-wheels E and I, filling the compression-chambers l and 2 as they are advanced in their proper sequence, whereby it is apparent that the facets :l: will enter the compressor-chambers 2 and the facets c will enter the compressor-chambers l, by which it will be seen that the material contained in the compression-A chambers will beV compressed, and by reason of the great pressure applied, combined with the heat maintained, it will be solidified into fuel units corresponding in contour substantially to that as shown in Figs. l1 and 12. As the machine advances the fuel units thus formed will be released as the compressionwheels pass their point of contact and the units will fall upon the constantly-InovinCr carrier 61. Should the fuel units fail to fall from the receding chambers of their own weight, then in that event the knockers M and N will press them out when they arrive at the point to be engaged thereby.

While I have shown and described the best means to me known at this time for carrying out my invention in a practical manner, I desire to have it fully understood that I do not restrict myself to the exact details of construction shown and described, but hold that any changes or variations in such details as would suggest themselves to the ordinary mechanic would clearly fall within the limits and scope of my invention.

There are no natural divisions between the variousmechanisms described, vthey all beinU operated from a single source of power, an the various parts are so nicely proportioned that the various operations of the machine follow each other in proper and harmonious order and with certainty and precision, thus producing a machine in which each of the elements thereof operate together for the production of a single result.
