APPARATUS FOR THE MANUFACTURE OF PEAT FUEL.
SPECIFICATIQN forming part of Letters Patent No. 390,545, dated October 2, 1888.
Application filed July 9, 1857. Serial No. 243,888. (No model.)
I aZZ whom it may concern.-
Be it known that 1, DAVID AIKMAN, of the city of Montreal, in the district of Montreal and Province of Quebec, Canada, have invented new and useful Improvements in the Machine for llIanufacturing Peat Fuel and in the Mechanism Used Therefor; and I do hereby declare that the following is a full, clear, and exact description of the same.
This invention relates to a particular con struction of mechanism adapted for producing peat fuel, which is arranged not only on a scow, which can be moved about over the peat-bog and thus out the peat and deliver it on board the scow, but also so that the peat so cut and delivered on board of the scow is passed by the apparatus from one part of the mechanism to the other without any manual labor until it is discharged from the mechanism in a state ready for the market. This is looked upon as an important feature of theinvention, because of the large amount of manipulation required to be given the peat to render it asuitable or a desirable fuel in the market, and the low price at which it is necessary to vend it to render it an economical fuel, so that it cannot be manufactured with profit if much manual labor is required.
The particular construction or combination of mechanism or parts in the apparatus about to be described which form my present invention will be hereinafter fully set forth and claimed.
In the drawings hereunto annexed similar letters of reference and numerals indicate like parts.

Fig. 19 is a plan, and Fig. 20 is a side elevation, of the ratchet-lever by which the ratchet-wheel d is operated. Fig. 21 is a double diagram comparing the positions of the plungers 6 k", and 1- at different positions as the shaft 0 revolves. Fig. 22 is a side eleva' tion of a portion of the plungers k and i", showing grooves a therein. Fig. 23 is a section on line on, Fig. 22.
Letter a is a scow of suitable dimensions for carrying the apparatus or mechanism hereinafter described. This is provided with an upper deck, b. The front end ofv the scow is provided with excavating-screws c and an elevator, d. e is a steam-engine arranged with an ordinary system of shafting (not shown) to operate the excavating screws c, elevator 01. and other moving mechanisms, to be hereinafter described, by gear-wheels or pulleys and belts in an ordinary manner. The said elevator conveys the material excavated by the screws 0 and delivers it into a hopper,f. The whole of this is constructed and arranged substantially the same or in a similar manner to What is described in patents granted to James Hodges, as follows: Patent of the United States No. 53,985, granted April 10, A. D. 1866, and patent of the Province of Canada, No. 1,928, granted November 27, A. D. 1865. The raw peat received in the hopperf falls through it into the transverse troughs g and h, provided with what are called and known as stick-catchers. These stick-catchers are fully described in the aforesaid patents granted 'to the said James Hodges, only that in this case they are arranged as right and left handed screws to convey the peat to the longitudinal distributing-spouts 2',- otherwise they would convey the peat to only one of the said spouts i.
In the troughs g and h steam-pipes 7c are situated for the purpose of discharging live steam into the peat as it passes through the troughs of the stick-catcher. This is one of the important features of my invention, as it reduces the amount of manipulation required to extract the sticks, &c.; it reduces the peat by the addition of water thereto; it also heats the peat, and the said heating of the peat reduces the amount of condensation of the steam in the rollers by which such pulp is afterward treated, as will be hereinafter described.
In the spouts 13 (see Figs. 6 and 7) conveyers are placed. These consist of a shaft, Z, supported at intervals by bearers m and provided with screw blades or vanes at, so that by turning the shaft and vanes in the proper direction the peat will be propelled in the spouts from the troughsg and it toward the aft end of the scow.
In the bottoms of each of the spouts i openings m are formed (see Figs. 5 and 7) at suitable intervals to have one of the openings perpendicularly situated over each pair of rollersn 12, located, as shown in Figs. 1 and 5, below the spouts i.
By Figs. 1 and 2 it will be understood that a number of the pairs of rollers n n are situated under each of the spouts t', the number of these pairs of rollers being according to the amount of work to be accomplished in agiven time.
The rollers n n consist of hollow corrugated cylinders of equal diameter andsize and number of corrugations, arranged together so that the elevations of the corrugations of the one roller will bear upon the depressions of the corrugations of the other roller. These rollers revolve in the directions as shown by the arrows in Fig. 5, and are set close up to each other, so that as the peat falls from the openings m" in a semi-liquid state it fills, partly,the space 0 between the two rollers n n,and, being taken or caught by the corrugations, is continuously fed between the rollers and adheres to the face ofeach roller in a thin film. As the rollers revolve, these films are carried round on their faces, and before they reach the scrap ers q are dried by the heat of the rollers.
I would here explain that the rollers n n are not for the purpose of crushing or grinding the peat, for it has been hereinbefore stated that the peat is reduced to a pulp before it reaches the rollers; but they are for the purpose of drying the peat and reducing it also to a suitable form for being delivered to a press or presses, as hereinafter described. The employment of a means of thus drying the peat at this stage of the process and the means are both important features in the present invention, for, again, plain cylindrical rollers will not answer my purpose, for from actual practice I have found that they will either not work or if they do so they do it by fits and starts, and as the peat falls continously from the openings m the rollers are at times overflowed with peat, causing much manual labor and loss of time to get cleaned up and started again.
Each of the rollers n is provided with a scraper, g, which may consist of a plate of steel extending the length of the roller and situated in relation thereto as shown in Fig. 5. These scrapers are held in place by springarms T, which are sufficiently flexible and set with such tension that they yield to and follow the corrugations passing under their edges, while said edges are at all times kept to a fair bearing upon the rollers. By this means the dried films of peat are removed from the rollers and fall into an elongated hopper, 8, thus cleaning the surface of the rollers as they revolve to receive continuously a film of pulped peat which has before been cleared of sticks and reduced to a pulp or homogeneous mass.
The scrapers q need not be formed in one plate if it is desired to form them in sections, each section being attached on one or more spring-arms, r.
The ordinary arrangements will be made, as shown, where, by a pipe, t, steam will be introduced into each roller n, and by a pipe, at, the steam and water of condensation will be carried off. Each pair of rollers is further provided with a pair of gearwheels, 1), to cause them to revolve equally and steadily with one another. This is arranged in an ordinary manner.
10 are bearings for carrying thejournals of the rollers. (See Fig. 4.) A suitable frame work or support (not shown) will be formed in the scow for these bearings 10.
The hopperssare preferably formed through out of sheet metal, and must at the top be sufficiently wide and long to receive the dry peat falling down from the rollers 12 it. Under the bottoms to ofthe hoppers systems of heatingpipes b are placed. These and the hoppers are carried by any suit-able supports, 0, (see Figs. 8 and 9,) from the bottom of the seow. The sides of the hoppers s are placed at such an angle that the dried peat will not rest thereon, but will slide down freely to the bottoms a.
Over the bottoms a conveyers d are caused to travel continuously. These consist. each of two endless chains, 0, to which are secured transverse metallic slatsf at suitable intervals.
The conveyors d are carried upon and op- IIO erated by revolving rollers g 9, (see Fig. 1,) situated beyond the ends of the hoppers, an opening being formed in each end of the hoppers for the chains 0 and slats f to pass in at the forward end and out at the aft end of the hoppers, the motion being in the direction of the arrow shown in Fig. 1, whereby the peat is brought toward the aft end of the scow, passes over the aft rollers, g, and falls off.
Were the height at which the peat falls off the roller 9 sufficient it might fall at once into the receiver of a press, hereinafter to be described; but as,shown,itis not. Therefore an elevator, h, is interposed todischarge it into the receiver i of a press or a number of p resses, It. When the elevator h is used, it must be provided with a system of heater-pipes, Z, to prevent the temperature to which the peathas been raised from being lowered at the said elevator, and thus delivered to the receiver t" not in a properly-heated condition. Ishould say that the heat at which the peat should be delivered to the receiver t" must not be less than about 120 Fahrenheit, and it would be U better to be far above that point.
0 is a boiler of ordinary construction by which the steam for the engine e, stea1n-jets 7c, and rollers a, and systems of heater-pipes b and l is provided. Of this n is the chimney, a sufficient space bcingleft between the engine and boiler to form a proper stoke-hole.
We now come to the construction and arrangement of the receiver 2" and press 7c,which are arranged for further heating the peat by pressing it to separate the natural tarry matter, as will be hereinafter described, and then pressing it into blocks or masses, or else carbonizing the peat and so pressing it. In either case the peat is discharged. from the press ready for the market.
In constructing the press it must be remembered that before beginning this work the s ze and shape of the blocks or masses into which the peat is to be pressed must be determined and the construction made according thereto. The said construction and operation of the receiver z" and press it are shown by Figs. 11 to 23, inclusively. Here (6 is the frame of the press, in which are formed bearings b for the journals of a revolving horizontal shaft, 0, on which are secured a cam, cl, two eccentrics, 6 a gear-wheel, it, by which motion is imparted to the press, and a crank-bearing hav ing a crank-pin, On the upper part of the frame a a face, If, is formed, which is trued up, and to it is attached, by bolts and nuts P, a cap, 01 thus forming a guide to a neck, 0 This neck is made integral with a crosshead, 1), through which passes a shaft, 1
The shaft q is provided with journals 1*, on which are placed blocks 8*. On the eccentrics e are placed strong eccentric-straps a, which are united together and with the blocks 3 by rods t passed through suitable openings or eyes formed in the said eccentric-straps and through the blocks 5 and secured with nuts u, as shown, whereby the distance that will be left between the plungers 7t and i may be easily adjusted, as will be understood by reference to Figs. 12 and 21.
@218 a frame having an opening, aflin itfor the center portion of the shaft 0 to pass through transversely, and the two sides of the frame being sufficiently apart (see Fig. 14) for the cam d to revolve freely between them. In the frame o is pivoted a roller, b the periphery of which is arranged, as shown in Fig. 12, to roll upon the periphery of the cam (1 The frame 12 is also provided with an upper extending neck, 0 and lower extending neck, The neck a is guided by a face, 0, formed on the frame at", and cap f attached to the said face by bolts and nuts, as shown. Similarly the neck d is guided by a face, g, and cap h, so that by the revolution of the cam cl the frame 12 is moved up and down and is securely guided in such motion.
On the top of the neck 0" is attached a plunger, i of the configuration and size that the blocks or masses of peat are to be pressed into. In this case we will suppose it to be round or cylindrical. On the end of the neck 0" is secured a plunger, is, of equal diameter to the plunger 2' These two plungers i and form the opeiative followers of the press.
To the frame a are attached two disks, Z and m. These are horizontally situated, the disk Z" being made integral with flanges a and the diskm being made integral with flanges 0. These flanges extend backward over the sides of the frame (l to which they are securel y attached.
The disks 1 and m must be faced up true and placed at a suitable distance apart to re ceive between them and fit closely upon a perfectly true and parallel cylinder or table, Q3.
The disk Z is provided with openings at 1 and 2, Fig. 13, for the plunger is and plunger '1', hereinafter described, to pass through. The disk at is provided with an opening at 1 for the plunger 2' to pass through, and with an opening, 3, situated immediately below 2, but is somewhat larger, as shown. The openings at l in these two disks closely fit their respective plungers, which they assist in guiding.
The table q consists of a disk or cylinder formed witha number of cylindrical openings, at. As shown, these are six in number, (see Figs. 16 and 17;) but a greater or less number may be used. These openings must be equally distant from the center of the cylinder or table qi and equally distant from one another, being also equal in diameter to the plungers i and k being further situated to come immediately over and under the plungers, so that the plungers move and pass through the disks l" and m and both pass into one of the openings a", and thereby form a mold in which to compress the peat. ably provided with bushes b", of brass or noncorrosive metal, to prevent the openings a from being eaten by rust.
c is a vertical shaft passing through the disks Z 112. and table g the said shaft being The openings at are preferformed, suitable either for the application of securely fastened in the said table, while the said shaft is fitted to revolve freely through the said disks. On the shaft c is secured a ratchet-wheel, d". The lower end of the shaft 0 is provided with a stuffingbox, f, to receive a steam-pipe, a A passage, 9, is formed in the shaft to the height as shown. (see Fig. 12,) and by a horizontal passage, it, connects with an annular chamber, 1?, formed in the cylinder or table g. This is for the purpose of introducing superheated steam into the said annular chamber and keeping it and the plungers hot.
As hcreinbefore stated, z" is the receiver, situated, as shown in Figs. 11, 13, and 15, partly over the disk Z". This receiver consists, as shown in said figures, of a cylindrical vessel provided with a double bottom, leaving a space, Z, for the introduction of steam for heat- On the bottom of the receiver t is formed a shoe or bearing for the foot of the shaft m to revolve in. This shaft is provided with arms a, of the configuration shown, so that by revolving the arms a'flwith the shaft m, in the direction of the arrow in Fig. 13 the peat placed in the receiver is forced downward upon the heated bottom of the receiver t" and outward into a projection, 0 of the receiver t. Here it falls through an opening, 6, formed in the bottom of the projection 0, and through the disk i into one of the openings at in the cylinder or table q, one of which will be always set to receive it,while another of the openings a, at 1, is having the charge of peat contained in it pressed, the revolution of the table being in the direction of from 6 to 1.
When it is desired to carry the heating of the peat to such an extent that it will be carbonized or reduced to a charcoal, the receiver 2", instead of being formed as hereinbefore described and as shown in Figs. 11 and 15, will be constructed as shown in Fig. 15, where a represents a cylindrical vessel, into which the peat falls from the elevator h, as before. Under this vessel a is arranged a second vessel, a, and in this case the projection 0 for the passage of the peat into the table q is formed in connection with the vessel a. Under the bottom a of the vessel a a chamber, a, is
fire direct to the bottom a or for the application of very highly superheated steam. In this modification the shaft m will pass t-h rough both the vessels or chambers a and a and be provided with arms a at about the bottom of each of them, as shown. In the bottom a an opening, a is formed. By this arrangement the free circulation of air in the vessel or chamber a is prevented by the peat at the bottom of the vessel or chamber a and its falling through the opening a. The shaft m is in this case carried by any suitable bearing, a", formed above, as shown.
On the lower end of the shaft 0, and arranged to revolve it by, as before stated, a ratchet-Wheel, d", is secured. This is operated in an ordinary way by a lever and pawl, z,
(shown only detached in Figs. 19 and 20;) but vention.
cr" is a guide situated over the opening 2 in the disk Z for guiding the plunger W. This guide is preferably made integral with the wall of the receiver 6.
b is a lever pivoted at c to any fixed body attached under the deck I) of the scow. Atits opposite extremity is attached a connectingrod, d of ordinary construction, connecting with the cranlcpin i which thus causes the lever b to vibrate in the manner indicated and impart through a link, 6 the required amount of motion to the plunger r The parts ofthe press being in the position shown in Figs. 11 and 12, and the peat from the hoppers introduced into the receiver 1'', Where its heatis very considerably augmented, one of the openings a of the cylinder or table q is charged with the heated peat by the retation ofthe shaft in" and arms it. These arms also break up and thoroughly mix the peat. As soon as the first hole is full, the table q is turned and the next opening a brought to the position 6 and filled, and the table q is again rotated. The plungers it, i and 1" must now be put in motion, and when the third opening a is being filled the first one filled will have been moved to the position 1, Fig. 13, where the charge of peat in it will be pressed by the plungers 7c and i, and as the table g rotates and brings the compressed charges of peat round to the position 2 they are expelled by the plunger 0".
A double diagram of the act onof the plungers 7c, '6", and r is given in Fig'. 21. In the left-hand side of this figure the parts are in the same position asthatshown in Figs. 11 and 12,in which position the said plungers k and i have just pressed a charge and the plunger 0' has just expelled a charge. Ifthe shaft 0 is rotated one-half of a revolution,it will cause the said three plungers to come to the positions shown in the right-hand part of Fig. 21, at which time the cylinder or table g is 1'0- tated, as hereinabove described.
In Figs. 22 and 23 it is shown (but not elsewhere) that the plungers 7c and i are provided with longitudinal peripheral grooves at. These are an important feature in my invention, as without them,although the plungers are made smaller than the recesses a, yet the air in the peat will not eseape,but will be locked in,and when the pressure is withdrawn it will expand and the solidity of the mass be destroyed.
The peat treated as above described is produced in the form of very hard blocks of specific gravity approaching that of coal ata very slight expense, as no manual labor is required in handling it until it is expelled from the press, and by having the mechanism situated on a scow the whole apparatus is able to follow up its own work by moving it about in the canals cut by it.
\Vhat I claim, and Wish to secure by Letters Patent, is as follows:
1. The combination, in a peatfuel-nianufacturing apparatus, of the troughs gand h,in which the peat is received, having stick-removing apparatus, as described, and pipes is, arranged, as shown, to admit jets of live steam at the bottom of the troughs g and h, spouts 6, having conveyers m and openings m", hollow corrugated steam'heated rollers a it, having pipes a and L, upon which the semi-fluid peat is received, spread out, and dried in the form of thin films, and scrapers q, the whole sub- 7 stantially as described.
2. The combination, in a press for pressing hot peat into blocks for fuel, of the revolving table or cylinder q, provided with a recess, 1', for heating it by steam, as described,with the operating-plungers k and i, operated as described, and provided with grooves a, as described, whereby the said openings a and said plungers form a heated mold having passages for the escape of the air contained in the peat that is being pressed within the said mold, the whole substantially as described.
3. The combination, in a press for pressing peat into blocks for fuel, of the revolving table or cylinder q, provided with a recess, 2'', for heating it by steam, as described, also having opening a", as described, with the operating-plungers k and i operated as described, whereby the said openings a and said plungers form a mold in which the peat is pressed into the desired blocks or masses, the whole substantially as described.
