To all whom it may concern:

lie it known that we. FRANK l-l. Enswon'rri and CHEUILES L. Dom-31.1.. residents of Anderson, in the county of Madison and State oi Indiana, have invented certain new and useful lin n'ove rents in l-lrioueting- Mochines; and we do hereby-declare the following to he :1 full, clear, and exact descriptioi'i of the invention, such. as will enable others skilled in the art. to which it nppertziins to make and use the some.

Our invention relates to improvements in hriqneting machines. the object of the invention being to provide Wheels having peripheral molds with improved means for heating the molds, improved means for applying end ressure t0 the briquets in the molds, and improved means for compensating for overcharge of the molds and maintaining the machine in gear.

With these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts as will he more fully hereinafter described and pointed out in the claim.

In the accompanyingdrawings, Figure l is a view in side elevation illustrating our improvements. Fig. 2 is it view in cross section. Fig. 3 iso section through a mold Wheel. Fig. at shows the form of hriquets and Figs. 5 and 6 are modified shapes of mold wheel peripheries.

represents a supporting frning'provided with fixed hearings for a shaft 3, and movable hearings 4 are also secured on frame 1 and in which nshnt't is mounted.

These bearings 4::318 provided with slots to I reeeive bolts 6. tosecnre them to the frame and the slots permit movement of the beerings on the frame Within certain limits, for a purpose which will hereinafter appear.

On shafts 3 and 5, mold wheels '2 andtl respectively are secured. These mold Wheels are provided in their peripheries with curved pockets 9 or moldseut at any angle to the axis of the Wheel and curved teeth 10 between the pockets to fit in the pockets of the other Wheel and complete the molds in which the hriqnets are pressed, material heing' supplied from a. hopper 11, located above and between the Wheels.

The shafts 3 and 5 are bored to receive hollow cylinders 12, and the latter are divided by a partition 12 into steam inlet and exhaust chambers. These steam ehnmbers with ducts leading to annular steam.

have revolving joints 1:? connected by .13 to convey steam thereto and there. on,

and inlet and exhaust pipes ll and nee-t the respective chmnbers of the cylinders sages in the rim portions of the mold w. and by this means the molds are kept warm to prevent sticking of: the hi'iqnets therein and steam hoods b shops in cross section. en 6;"; compass the greater portion'of the Wheels to keep them heated. V

To give the necessary end..pressnre to v hriqnets in the molds, blocks 16 are ad ust ably secured to the frame 1 by oolts l? and have curved or rounded enlargements 18 at their inner ends located against. the'ineeting edges of the mold Wheels, and as the latter carry the briqnets down between the curved or rounded enlargements 18. the hriquets Will be given the necessary end pressure to press them into pro er f'rni." The enlargements 1S h-sve steam connected to the pipes 13, and Wheels 19 are. located at the hotjt Wheels 7 and 8 and are provided with {in gers 20 to move through, the .molds and eject any briquets that may stick.

The shafts 3 and 5 are connected by large gear wheels 21, oneof'which being driven by any desired ineeher' n ind the teeth or these 21 are Sllll'lt 37 lonu to thshafts 3 and 5 to he moved so thor than normal distance apart on overcharge of material. in the molds rompensete for this movement of the shafts,

the sliding hearings 4 are provided. and are engaged by the short arms of he levers 2-2, pivoted. in brackets and the long; arms of the levers are con ed by a cross her and held down e co? spring 24. which letter will he i' when the hearings 4: move beckon will drew the hearings heel: to norn .1 ing position, when the excess of passed through.

Figs. 5 end 5 illustrate slightly modified forms of mold wheel eripheries.

Sli ht changes migit'be made in the generi l 'orrn end. arrangement of the ports described withont departing from our invention and hence we would have it understood that we do not restrict ourselves to oise details set forth hut consider ourselves at liberty to moire sneh slight chooses and alterations fairly fell witiin the spirit 'and scope of our invention.
