SPECIFICATION forming part of Letters Patent No. 741,511, dated October 13, 1903. Application filed February 11, i903. Serial No. 142,918. (No model.)

To all whom it may concern:

'Be it known that I, HENRY GRANT LAYNG, a citizen of the United States, and a resident of the borough of Manhattan, city, county, and

State of New York, have invented certain new and useful Improvements in Briqueting- Machines, of which the following is a specification, accompanied by drawings.

My invention relates to briquetingmachines, but more particularly to rotary briqueting-machines; and the objects of my invention are to improve upon the construction of such machines and decrease the shearing efiect upon the briquets in process of formation without unduly increasing the diameter of the wheels provided with the molds.

Another object of the invention is to obviate excessive strains upon the machinery and obtain the maximum efficiency with as simple and strong a construction as possible.

Further objects of my invention will hereinafter appear; and to these ends my invention consists of a briqueting-machine embodying the features of construction, combinations of elements, and arrangement of parts having the general mode of operation substantially as hereinafter fully described and claimed in this specification, and shown in the accompanying drawings, in which- Figure 1 is a side view of my improved bri-.

quoting-machine. Fig. 2 is an end view of the same. Fig.3 is aplan view, partly in horizontal section. Fig. 4 is a side view of a portion of the operating machinery; and Fig. 5 is a detail view of the beveled wheels provided with the racks and molds, a portion of the rims of the wheels being in section.

Referring to the drawings, the wheels A are provided with the cooperating molds B, arranged in the inner beveled edges of the wheels. The wheels, as shown, are set at an angleto each other, with their rims at a tangent, and the material is fed downwardly from the hopper 0 into the molds,-which form the briquets under pressure as the wheels are revolved toward each other and drop them beneath the wheels. By arranging two wheels as shown, with beveled inner surfaces provided with the mold-sections B, it will be seen that two rotating beveled surfaces are obtained, which, in efiect, are equal to the surfaces of wheels of very much larger diameter than are the actual diameters of the beveled wheels used. The great advantage of wheels of large diameter is obvious in that the shearing effect upon the material compressed in the molds in the form of briquets is greatly decreased and much better results are'obtained than with wheels of small diameter, as is Well known in the art. The outward pressure between the rims of the wheels when the material is being formed into briquets is necessarily very great, and suitable means are provided for rotating the wheels, while at'the same time provision is afforded for resisting the outward pressure, and thus obviatingstrains upon the machinery. I'have found that by driving the wheels from the rims instead of from center shafting much better results are obtained than heretofore, and according to myconstruction I provide the outer beveled edges of the rims of the wheels with teeth forming circular racks D, meshing with the beveled pinions E, connected to be actuated from a suitable source'of power.

Suitable means are provided for rotatably supporting the wheels A, as shown in this instance they being supported upon the grooved rollers F, carried upon the frames G and H. The frame H, as shown, also carries the hopper C, which in this instance is provided with an adjustable plate I for limiting the size of the hopper and the amount of material fed in a given time. The-plate I, as shown, is provided with ears J, and the sides of the hopper'are provided with rows of holes K, so thatthe plate I may be adjusted into different Vertical positions and maintained in a given position by means of suitable pins L. In dismounting the machine it will be seen that the wheels A may be readily lifted from their supporting bearing-rollers F, and

the parts may thus readily be reassembled.

Power is applied to the pulley 0 upon the driving-shaft P, which is provided with the pinion Q, meshing with the gear R upon the shaft S, which gear in turn meshes with another gear T upon the shaft U. The beveled pinions E are also carried upon the shafts S and U, to which shafts are also connected the guide-rollers V, adapted to bear upon flattened portions of the rims of the wheels A and press the rims together. The guiderollers V also aid in taking the outward thrust from the rims of the wheels A.

Any suitable bearings may be provided for the shafts S and U; but as shown in this instance I have provided roller bearings. (Illustrated more particularly in end view in Fig. 2.) These roller-bearings may be of any suitable construction; but I have found that roller-bearing particularly applicable which is fully disclosed in the application of Fred E. Brooks, Serial No. 110,339, filed June 5, 1902. The bearings for the shaft S, as shown, are stationary and form a part of the frame W of the machine, while the bearings X for the shaft U are movable along the slides Y transversely of the machine. This construction is provided in order that the beveled pinions E may be kept firmly in mesh with the circular racks D upon the wheels A.

Rods Z extend transversely through the bearings of the shafts S and U and also through adjustable blocks or abutments a. The rods Z are provided with screw-threaded portions, upon which the nuts I) are screwed, firmly clamping the bearings of the shaft S. Between the bearings X of the shaft U and the movable blocks a are arranged the coiled springs 0 under constant compression. The nuts d serve to adjust the blocks a upon the rods Z. Suitable stopsf are provided upon the rods Z adjacent the bearings X and at the opposite sides of said bearings from the springs 0. According to the construction shown it will be seen that the springs a constantly tend to press the bearings X and the shaft U, together with the beveled pinion E and roller V, upon the shaft U against the rim of the wheel A, thus afiording means for firmly grasping the rims of both wheels A between the beveled pinions E and rollers V. The tension upon the springs 0 may be varied as desired, according to the construction shown, and the distance between the bearings of the shafts S and U may be varied by adjusting the nuts 1).

Obviously some features of my invention may be used without others, and my invention may be embodied in widely-varying forms.

Therefore, Without limiting myself to the construction shown and described nor enumerating equivalents, I claim, and desire to obtain by Letters Patent, the following:

1. In a briqueting-machine, the combination of cooperating wheels having beveled edges provided with molds, and mechanism for driving said wheels from the outer sides of the rims and for taking up and resisting spreading strain on the wheels at the moldingpoint, forsubstantially the purposes set forth.

2. In a briqueting-machine, the combination of cooperating wheels having beveled edges provided with molds, circular racks upon the outer sides of said wheels, pinions meshing with said racks at the molding-point,

and means for actuating said pinions, for subracks at the molding-point for taking up spreading strain on the wheels, and means for actuating said pinions, for substantially the purposes set forth.

4. In a briqueting-machine, the combination of wheels having beveled edges and being provided with molds, said wheels being rotatably supported at an angle to each other and with their rims at a tangent, and operative mechanism connected at each side of the tangent portions of the wheels to drive said wheels from the outer sides of the rims, for substantially the purposes set forth.

5. In a briqueting-machine, the combination of wheels having beveled edges provided with molds, said wheels being rotatably supported at an angle to each other with their rims at a tangent, circular racks upon the outer sides of said rims, and pinions meshing with said racks at each side of the tangent portions of the wheels opposite the moldingpoint for taking up spreading strain on the wheels, for substantially the purposes set forth.

6. In a briqueting-machine, the combination of cooperating wheels having molds and arranged at an angle to each other, circular racks upon the outer sides of the rims of said wheels, pinions meshing with said racks at the molding-point, and guide-rollers at each side of the wheels at the molding-point for taking up outward thrust, for substantially the purposes set forth.

In testimony whereof I have signed this specification in the presence of two subscrihing witnesses.

HENRY GRANT LAYNG.
