'/o all iii/ioni it muy concern:

lie it known that l, Jauizs JouN Sinini.oeii, engineer, a subject of the King of ti'eat liritain, residing at Little Bentley, in the county of Fissex, linglaud, have invented certain new and useful Improvements in liriquet-Presses, of which the following is a specification. l

'lhis invention has for its object improvements in or reliitiiig to appariitiis for molding and compressing purposes such as the manufacture of briquets or the like; and although more particularly designed for molding and pressing artificial fuel material into blocks or briquets nevertheless my said invention may be employed for any other purposes to which it may be applicable, as t'or exemple, for molding and pressing ore briquets, or for molding and pressing eartheiiwai'e articles, such as tiles.

'1`he present iiiveution comprises the hereinafter described method of operating apparatus for molding and compressing purposes for use. in the manufacture of briquets or the like wherein the. firstand greater part of thc con'ipression stroke of the compression mechanism is produced by mechanical action and the final part. of the compression stroke is produced by hydraulic action siich method consisting in mechanically imparting motion to the hydraulic ram head and ram for the first and greater part of thc pressure stroke thereof by Vmechanical means and while thus mechanically imparting said motion to the ram head and rain causing or permitting water at little or no iressure (c. g. water at at mosphcrc pressure) to enter the hydraulic cylinder and keep same full asthe ram is iiiechanicallv moved outward as aforesaid Iand then admit. high pressure water to said cylinder for the final part of the compression stroke; this method producing not only considerable economy of high pressure water but also enabling the hydrau ic pressure at the end of the stroke to he maintained (i. a. dwell and follow) upon the iniiterial to be compressed for the desired period.

Apparatus for molding and compressing purposes according to the present invention comprises a molding chamber or chambers (which may bc provided with dies of any desired forni or size) a plunger adapted to be reeiprocated in each said chamber and p or operating said plunger said means L comprising n framc mounted on a hydraulic i ram, mechanical iiieaus for operating said frame aiul ram through the greater part of the pressure stroke, means for'simultancously filling the hydraulic cylinder with water at little or no pressure., and means to then admit water at high pressures for the remainder of tho pressure stroke.

In conjunction with the foregoingthe present invention also com )rises other details and im irovcmcuts al as hereinafter described and claimed. And in order that my present. invention may bc the more easily understood and readily carried into practice I will now proceed to describe saine with reference to the accompanying drawings which illustrate my invention as designed for a fuel press or fuel biiqueting press.

Similar letters of reference indicate cori responding parts throughout.

a. is a horizontally rotating mold table of the well-known type provided with a series of pockets and molding chambers o therein-which may if desired be provided with i dies to produce briquets of any desired form or size. This horizontal rotiitable mold table a is moved around step by step in any known or suitable manner for example as illustrated said mold table may be provided on the under side with n ring of bevel 1 teeth a2 which engage with a bevel toothed L wheel aa (see Figs. 1 and 3) which latter in turn is o ierated by ratchet. wheel a fixed on the spindle a". This ratchet wheel carries a pawl or pawls which in one direction engage and rotate the wheel n, and in thc other direction move idly over same` and said ratchet wheel is reciproeated by means of; the connecting rod I) which latter at one end b' is ivoted to said ratchet wheel (see Figs. 1 an 3) and at the other end is connected at b to the crank Ii on the main shaft c. This mold table is moved around step by step in thc known manner and no claim is made herein to either the mold table per .ic or the method of operating same.

Any suitable means may be ein iloycd for filling the molds or mold chambers a in the mold tiible a. and as such means of filling said molds in briquet presses are well-known and in common use therefore it is not necessary to further describe same. here.

'l`ho aforesaid shaft c is operated from anv suitable source of power as for example saiil shaft c may be operated h v means of a belt on the fast and loose pulleys o'. which rotate the shaft d aml the latter through a worm ai2 rotates the worm wheel 117 on said shaft e.

I.' and ram i (all in vertical ahncment) cam l is in its lower position as indicated in said figures. The rotation of the cam Z (by touffue m and the latter acting on the frame 1 /r orccs upward said frame r. and ram 1, attached thereto for such part of the travel during the 'g pressure stroke for example in the arrangemeut illustrated the frame l.: together with the ram i will be mechanicallymoved (by said cam action) through th'e greater part of fthe compression stroke viz. about. three-t fourths or four-fifths of said stroke and dur: l ing this mechanical movement of the ram z i water at little or no pressure is caused or permitted to enter the cylinder c from the with water during the outward mechanical movement of the ram 2' and at or toward the i i l n cisteru f so that said cylinder is thus filled i t end of this mechanical outward movement y (during which,the fuel material has been 5 partly compressed) the tappet arm t then operates the valve g and admits high pres- ,j sure water to the cylinder c so that the ont- -.j stroke of the ram i l draulic pressure and the final compression i thcrcbv im iartcd to the material in t ie mold chamber a. and this livdraulic pressure on the fuel material is maintained and allowed z` to dwell thereon for a certain period viz. 1 during the. time the caml Z is revo ving fr oui its up icrmost position into such a position as will permit the cani-piece to descend to g such au extent as to cause the tappet arm t l to close'the valve g from the high pressure supply and ierinit theI esca ie of the water from the ey inder c througi the passage z the pipe y* the valve g' and pi ie 1a. to the cistern f. After thus cutting otl high pressure water and o icning the exhaust. or escape from the cylinder c the cam Zby acting on the plate In iii the bottom of the opening /s in tlie frame 7.1 causes or assists in causing the descent of the ram z' whereby the water is forccd out of the cylinder c as aforesaid l 's now completed by l iy table ri is now moved on n step :ind the next filled mold chamber n ainl phiuger n is iaiii i and the pressure applied directly first,

inbefore described; and so on. be seen that by my invention thc hydraulic stroke of the hydraulic ram is variable owi ing to the adjustable and elastic limits of thc l mechanical device and ofthe fuel material or other materal to be compressed.

It. will be obvious that mv aforesaid iny ventioii may be ada tedto be carried into i practice or use-witi or without modificadifferent material such as ores or minerals (or materials containing orcs or minerals) 5 ing clay or earthenw'are articles, such as i tiles, etc. t Instead of employing a rotating table I containing a series of molds or molding chambers, my present invention may be carried into practice in conjunction with any other suitable form and arrangement of i mold or molding chamber` as for instance, i I may employ a reci rocatinfv table slide or idevice containing tie molds or molding i chambers, or I may employ only a single mold ory molding chamber. )Vhat I claim is 1. In an apparatus for molding and compressing purposes. tlie combination of a rotatably mounted table provided with a series of molding chambers, n lunger adapted to operate in the molding c iambers. a slidahlv mounted frame located in alinement. with the plunger, said frame being irovided with an opening. a revoluble siiaft passing through said opening, a cam qxed on the shaft and adapted to force sait frame np- 1 wardly for a part of the compression stroke of the plunger, a piston at the lower eml of l said frame, a cylinder for the piston, amt

means controlling the flow of water under pressure to tlie cylinder to complete the compression stroke of the plunger.

2. In an apparatus for molding and compressing pur ioses, a rotatablv mounted table provided wit a series of molding chambers", a plunger adapted to operate in the iiioldiug chambers, a slidably mounted frame located c into the oistern f when-"e itl can be used .l again as before described. 'I`he rotary mold brought into iosition over and in vertical` alinement witi the. aforesaid frame l.: and

mechanically and then h vdrinileally as here-r It. will thus4 pressure is not merely applied for an instant I Thus it will be seen that according to the present invention the.

tions as may bc requiredfor compressing 3 to be compressed into briquets, or for inakin :ilinenient with the plunger, said framel being provided with un opening having upwardly eonvergiiw sides, a V-sliaped member mounted in tic upper portion of said opening, a revoluble shaft passing through tbe opening, a cani on the shaft in engagement with the V-slinped member adapted t0 lift the ilunger for a part of its compression stro te, a piston at the lower end of said frame, a cylinder for the piston, and means forcontrolling the tlow of water under pressure to tbe cylinder to complete the compression stroke of the plunger.

8. In an apparatus for molding and coniprcssing purposes, a rotatably mounted table provided .with a series of molding chambers,

ber for opening a high p'ressiire valve to permit water to enter the cylinder for completing the compression stroke of the plunger. l

4. In au apparatus for molding and compressing purposes,a rotatably mounted table provided with a lseries of molding chambers, a plunger adapted to operate in the molding chambers, a slidably mounted frame located in aliiiciiient with the plunger, said frame bein f provided with an opening having upwart ly converging sides, a V. iaped meniber mounted in the upper port-ion of said opening, a reroluble s iaft passing through the opening. a cani on the shaft in engagement with the V-sliaped member adiipted lo lift the ilnuger for a mrt of its compression atroce, a piston at tlie lower end of said frame, n. cylinder for the piston, au urin exg tending from the V-shaped member for ;opening a high pressure vulve to permit; i water to enter the cylinder for completing the compression stroke of the plunger and to close said valve when the plunger has finished its stroke, and means for ermittiiig the escape of the water from tie cylinder.

In witness whereof I have hereunto set niy hand in presence of two witnesses.
