PEAT-HARVESTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 758,624, dated May 3, 1904,.

Application filed June 6, 1903.

To all whom it may concern.-

Be it known. that I, ALEXANDER DOBSON, millwright, of the town of Beaverton, in the county of Ontario, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Peat-Harvesting Machines, of which the following is a specification.

My invention relates to improvements in peat-harvesting machines; and the object of the invention is to devise a machine whereby the cost of digging and drying peat may be the conveyer, the parts being otherwise arranged and constructed in detail as hereinafter more particularly explained.

Figure l is a perspective view of my improved peat-harvesting machine. Fig. 2 is an end elevation from the same side, showing the conveyer and digging-wheel removed. Fig. 3 is a detail of the knife-wheel and bucket. Fig. 4 is a side elevation of the conveyer from the opposite side to that shown in Fig. 1.

In the drawings like characters of reference indicate corresponding parts in each figure.

A is the frame of the wagon; B, the wheels, which are broad, as indicated, and secured to an axle B, which is journaled on suitable bearings B depending from the frame. There are four wheels to the wagon, as indicated in Fig. -1, the-two rear wheels being not clearly shown.

C is a swinging frame, which is pivoted on the shaft C in bearings C on the main frame A. p

D represents supporting standards obliquely set and securely held in position by the braces D.

C represents the side boards of the swinging frame, which are connected together by Serial No. 160,44'7i (No model.)

the cross-boards C, on which is supported the motor E, and at the opposite end are provided with depending side bars C forming a depending frame braced by cross-bars c and diagonal bars 0 At the top of the bars G I journal in suitable bearings the shaft F, upon which is secured the pulley G, which is connected by the belt g to the pulley E of the motor.

H is a sprocket-wheel secured on the shaft F, connected by the sprocket-chain h to the sprocket-wheel I on the knife-wheel shaft J, which is journaled in suitable bearings at the bottom of the side bars G The disk K, rigidly secured to one of the bars C and through which the knife-wheel shaft J passes, acts as a shield for said knife-wheel. The disk or shieldK is provided with an offset portion K, at the upper end of which extends the arcshaped directing-chute K to which is hinged the straight chute K L is the knife-wheel, the buckets Z of which are substantially radially arranged, the buckets being U-shaped in cross-section,- as indicated in Fig. 3, and extending outwardly, as shown.

L represents the knives, which are arranged in a series along the outer side of the bucket and set obliquely, as indicated in Fig. 3.

M is a conveyer having the side boards m and the bottom boards m, such conveyer being secured in position on the front of the frame by suitable supports m and m The frame M, hereinbefore described, is the frame of an endless conveyer, comprising the endless sprocket-chains m, provided with the cross-slats of, such sprocket-chains being carried at each end by suitable sprocket-wheels m and m on the shafts 2 and 3, respectively.

N represents the lower side boards, which are suitably connected to the support m at one end and to the braces M at the opposite end, which are secured to the side boards m.

0 is a discharge-wheel comprising the substantially radial arms 0, connected together by the cross-blades 0. The discharge-wheel O is provided with a suitable shaft 0 which is journaled in bearings in the boards N at the discharge end of the endless conveyer, which moves in the direction indicated by arrow.

E is a sprocket-wheel secured on the end of the shaft Fand connected by a sprocket-chain E to a sprocket-wheel P on the end of the shaft 1), journaled in bearings on the side boards m of the conveyer-frame M.

P is a sprocket-wheel secured on the shaft 3) and connected by the sprocketchain P to the sprocket-wheel P on the end of the shaft 3.

P is a sprocket-wheel on the shaft and connected by a sprocket-chain P to the sprocketwheel 0 on the end of the shaft 0 ofv the discharge wheel or fan.

It will be noticed that the sprocket-wheel on the end of the discharge wheel or fan is much smaller than the sprocket-wheel on the end of the shaftSfor the purpose of imparting aswift beating, throwing, or spraying action on the peat when it is being discharged from the conveyer.

Q is a gear-wheel secured to the shaft q, engaged by the gear-pinion g on the spindle (1 -which is provided with the crank-handle Q3.

Q is a chain connected at one end to the shaft q and at the opposite end to one of the Gross-bars C of the wheel-frame.

Having now described the principal parts involved in my invention, I shall briefly describe its operation and utility. By the construction of my frame it will be noticed that the motor E is heavy, comparatively speaking, to the wheel-frame on the opposite end of the swinging frame, and is consequently on the short end of the frame for the purpose of balancing the swinging frame. In order to raise or lower the wheel-frame, I manipulate the crank-handle g and by this means wind up the chain Q, or let it out so as to depress the wheel-frame and bring the wheel L into the peat of the bog. It will of course be understood that the motor imparts motion through the pulley E, belt 9, and pulley G to the sprocket-wheel H, by which motion is conveyed by the sprocket-chain to the sprocketwheel I on the knife-wheel shaft, and thereby the knife and buckets are rotated. The operator of the machine by standing on the wagon can lower the knife-wheel as the peat is being cut, such knife-wheel rotating very rapidly and cutting a concentric or are-shaped cut into the bog, as indicated, the knife slicing off a side out as the machine is being propelled forward by means which it is not necessary here to describe. The knife-wheel being caused to rotate in the direction indicated by arrow cuts and pulverizes the peat and carries such pulverized peat through the arc-shaped chute K and out of the hinged chute K onto the conveyer M, the centrifugal force throwing the peat peripherally outward and tangentially onward onto the conveyor. By the conveyer M the pulverized peat is carried onto the discharge-wheel O, which revolving rapidly serves to spread the peat in very fine particles over the dried surface of the bog, and as the wagon moves forward necessarily the peat is spread. in a thin layer and will be quickly dried by the sun, and thereby relieve such peat of the greater part of the moisture, and thus reduce to a minimum the amount of artificial drying required. I wish also to draw attention to the advantages which I derive from my knife-wheel and the arrangement of the knives thereof, as I am enabled by such an arrangement to slice the peat into very thin shavings or layers, so that it is pulverized as it passes through the wheel, and when it reaches the discharge-wheel it is in fine particles for distributing onto the surface of the bog. I wish also to call attention to the manner in which the weight is distributed on the wagon. It will be noticed that the pivotpoint for the swinging frame is over the wheel on the solid bog and farthest away from the edge of the bog on which the knife-wheel is acting, and therefore the wheel on such edge, having but comparatively small weight as compared to the wheel on the opposite side of the wagon, will not be liable to break away the edge surface of the bog and ditch the wagon.
