To all whom it may concern.-

Be it-known that 1, WILLIAM ATKINSON MILNE, lumbernian,'of the village of Browns Corners, in the county of York, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Peat- Presses, of which the following is a specifi-.

cation.

My invention relates to improvements in peat-presses; and the object of the invention is to produce an economically-operated machine of this class which will produce perfect briquets of peat of a superior and uniform density; and it consists, essentially, of two meshing gear -wheels secured on suitable shafts having bearings upon a suitable bed plate or frame, the one bearing being station ary and the other adjustable, and two wheels, each on opposing shafts, provided with recesses in the 'peripheries' alternately arcshaped and angular, theangular recesses on one of the wheels being designed to come opposite to the arc-shaped recession the coacting wheel, so as to make the briquet's, and the sides of the wheels at their tangential point being inclosed by suitable bands suitably supported and fitting closely to the wheel, so as to form ends for the briquets, the parts beotherwise constructed and arranged in in deiail as hereinafter more particularly eX- plained.

Figure 1 is'a perspective view of a peat-press constructedin accordance with my invention.

Fig. 2 is a plan. Fig. 3 is a sectional detail looking upon the periphery of oneof the forming-wheels. Fig. 4 is an enlarged sectional detail of the forming-wheels, showing the W mannerin which the briquets are compressed and discharged.

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

A is the bed'of the machine.

B and B are the standards, which are suitably secured to one endof the bed and provided with suitable bearings b, in which the main driving-shaft G is journaled.

C is a counter-shaft which is journaled in suitable bearings d, which are held on the hinged portion 0 of the arms E, which are pivotally supported on the bed A by studs a. The upper ends of the arms are connected by a cross-rod F. l

G is a rod which extends through the boss f, formed at the upper end of the intermediate arm E, being rigidly heldtherein by nuts at each side. of the boss. The opposite end of the rod G extends through a boss b at the upper end of the standard B. The rodG is provided with a limiting-nut g.

H H represent two braces, through the eyeshaped ends of which the rod G extends at one end,-the opposite ends of the braces extending through the lugs 1;, formed on the end sleevesl I.

J is a spiral spring extending between the boss I) and the collar j on the end of the rod G, such collar being held in position by a nutj'.

K and K are the gear-wheels, which are secured on the shafts O and C, respectively, such gear-wheels meshing, as indicated.

L and L are the forming-wheels, which are provided with peripheries, having alternative arc-shaped and angular recesses Z] and Z Z. The wheels Land L are almost tangential, and are so arranged that the angular recesses of one wheel pass into thefinal compressing position always opposite the semicircular recess'es of the other wheel. It is absolutely necessary that this should be so on account of the sweep that the angular recess takes as the wheels are rotating toward each other in compressing. If they are both angular recesses, the peat-block could not be discharged.

' MandM'arebands,preferablymadeofsteel, which abut, the faces of the forming-wheels opposite the compressing-point. The bands are endless bands and are formed of one or more layers, and in order to reduce the-frictionI provide at the back of the bands two endless chains of rollers N and N, which pass Wheels being suitably driven frem the main shaft 0 through the merlinm of the gears the pest passes clown into the recesses, which are approaching each other astlie forming-Wheels 1 the highest compressingpeintc rotate, and thereby gradually increases in density until it reaches the point directly on a, line with the lev el of the shafts, Whirl"; is As the ferns ing wheels are still caused to rotate, the of the angular recess rese'ile from the ercshaped recess, and the blocks, now som ressecl, are gradually released by means of the opening'up of the recess by which they have been formed. 'It is preferable in the 1, formation of-the blocks tnettlie projecting points. of the wheel forming the recesses slightly overlap, so as to completely separate v or cut away tile briquet when formed from the preceding one, which is silly formed.

Its'ill be seen that if the when being compressed should become so dense as to exert a breaking strain on the peripheral cavities thatsuchstrain would be relieved by means 0f the adjustable bearing-erms E, spring-held, as hereinbefore described.

I By such a machine as l descriheit will be seen that thepower needed is reduces to 2; minimum, that the machine is elwsys ceznpressing", so that there is us lest time er no- W'neels might be arc-shaped, er the recesses in one wheel be ell angular enrl the other ere-shaped "Without departing: from the spirit of my invention,

What I claim as my invention is--- 1. In a peat-press lwo forming-wheels both having their peripheries divided inte eresliepecl and angular recesses, the ercshsped recess of'one wheel being designed to come substantially opposite the enguler recess of the opposite wheel. when they are on a level with the shafts as they rotate as and for the purpose specified,

2. The enmbinetion with the-wheels supported and driven and spproechingeech other eppcsitetheir centers, of the endless bends suitably driven and lisving plain surfecessnbstsntially abutting the feces oft'ne wheels whereby thehcpper'iznus fermed is of the same Width throughout and thereby form ends for the cavities or reeesses, and hacking-supports for the bands as egecilied,

3. The cembinstion with the forming Wheels supported 2,3351%} "Yen and approaching each other opposite tle centers, of the endless bands suitably driven and substantially abutting the feces of the Wheels, so as to form. ends for the cavities recesses and sellerelm insfcrxning a, bearing to the outside of the semis and suite-ole supports for such rollercliains as encl fer the purpose speeified.
