To all whomiz't may concern.'
Be it known that I, OLIVER ,I Moussnrrrn, citizen of the United Sta-tes, residing at Brooklyn, in the county of Kings and State of New York, 'have invented certain new and useful l Improvements in Ore-Pulif'erizers, 'of which the following is a specification.
This invention relates to Crushers or pulverizers and has for its object the provision of a comparatively simple and thoroughly etlicient machine of this character that may be used for grinding ores or reclaiming brass or other metals from. the refuse of refineries, foundries, smelters, andthe like.
A further object of the invention is to provide a crusher which Will efficiently perform the required work and Vwhich may be operated with relatively low power.
A further object of the invent-ion is to provide a crusher which by ysimple manipulation may be adapted to perform various kinds of work and which will be so constructed as to be readily assembled and possess great durability.
The stated objects, and such other incidental objects as will appear as the descrip.- tion of the invention proceeds, are attained in lan apparatus such as is illustrated in the accompanying drawings and hereinafter set forth. l A r In the drawings: Figure 1 is a side elevation of a crusher showing the preferred embodiment of my present invention; Fig. 2 is a horizontal section of the same; Fig. 3 is a side elevation showing a different adaptation of the invention, and Fig. 4 is a vertical longitudinal section showing a still further adaptation of the invention.
In carrying out my present invention, I employ a main supporting frame comprising side members 1 having horizontal ribs or flanges 2 along their upper edges to reinforce the same and connected at their ends by transverse webs or braces 3 which are formed ,integral therewith. The frame is provided with lateral feet-or supports 4 through which fastening bolts may be .inserted to secure the apparatus in position upon the floor of a work room or to any other convenient fixed support at the place where it is to-be operated. These feet 4 are also formed integral with the side members and at the ends of the said side mem- `bers and approximately at the junction of the said members and the transverse webs or braces 8, I form journal boxes 5 to receive the ends of shafts 6 as shown. The
journal boxes 5 areein the form of troughs o r cups havmgllanges 7 on their opposite sides, and mating troughs or cups 8, provided with similar flanges 9 on their oppo Y site sides, are placed over the shafts 6 and bolted to the lower journal bearing mem bers 5 by bolts y10 inserted through the flanges 9 and '7 as shown and as will be readily understood. Oil cu s 11 are preferf ably formed on the upper sldes ofthe sleeves or troughs 8 to contain lubricant which may feed by `gravity to the shaft 6 and thereby assure easy running of the machine.' Rollers 12, provided with side flanges 13, are keyed upon the shafts 6A and a shaft 6 is provided at each side of the machine as will be readily understood on reference to Fig. 2. Atthe center of one transverse web or brace 3 I secure a hollow stud 14 which prO- jects outwardly fromthe said brace and-has a casing 15 bolted to itsVy outer end. This casing 15 extends transversely of the machine and housed within the same are interi meshing gear wheels 16, the outer gear wheels of the train being fixed upon the ends form small ducts or passages 21, 22, to permit escape of the lubricant to the fast .pulley 23 and the loose pulley 24 thereon, a stop ring or collar 19 being secured on the support to prevent the pulleys working olf the same. The loose pulley 24 is mounted on the support between the fast pulley 23 and the stop 19, so that when it is desired to arrest the operation of the crusher the driving belt 26 may be slipped from the fast pulley, as will be readily understood. It will be readily understood that when the belt is in engagement with the fast pulley, the hub 17 thereof will be rotated and the intermediate gear wheel 16, keyed thereto, will consequently be set in motion so as to rotate the outer gear wheels and consequently rotate the shafts 6 with the rollers l2 thereon in` the same direction.
The drum is supported byA and upon the rollers 12 and is rotated about its own axis through its engagement with the said rollers. The driving rings 27 .are integral with the frame, as clearly shown, so that there is no possibility of the rings working loose and slipping around the drum without imparting motion thereto. The drum comprises two main members 28-29 whichare secured together at their meeting edges by flanges 30vand fastening bolts 31 inserted therethrough and tapered from the said meeting ends. The driving rings 27 are formed integral with the smalle` ends of the drum sections and are constructed with-flat outer faces, as shown at 32, against .which are fitted the terminal members 33, said members being firmly secured to the main members 28-29 by bolts 34 inserted through flanges 35 at the inner or wider, ends of said terminal lnembers into the bodyof the driving ring. The outer ends of the said terminal members are 'provided with annular flanges 36 against which I secure heads or caps which serve'as closures for the ends of the drum and which are of various constructions according to the particular use to which the drum is to be put as will now be described. In Figs. 1 and 2 I have shown the head 37 as consisting of a circular im-v perforate plate provided with a reinforcing annular rib 38 and securely bolted to the iiange 36. At the opposite end of the drum,
I secure to the flange 36 a head in the form of a mouth piece 39 having a flared portion provided with an annular fiange 40 fitting against the flange .36 and firmly secured thereto. The outer end of this mouth piece is also fiared, as shown at 41, and within the said flared outer end I insert a closure or cap 42 carrying bolts 43 having their inner ends formed into hooks 44 adapted to engage the inner edge of an annular flange or tubular neck 45 formed* in the mouth piece and preferably integral therewith. The cap 42 has beveled edges and nuts 46 are mounted von the outer ends of the bolts 43 so that if the hooks 44 be engaged over the tube 45 and the nuts thenv turned home, the cap will be drawn firmly into the outer flared portion 41 of the mouth piece and clamped within the same so as to positively close the endo the drum. To guard against leakage, packing 47 is preferably provided between the edgeof the cap and the wall1 of the mouth piece and similar packing A48 may be provided between the flanges at the inner meeting edges of the main sections of the drum.
The main sections 28 and 29 of the drum are preferably formed of comparatively soft metal to reduce the cost while the driving rings 27 formed integral therewith may have chilled peripheries to provide the necessary wearing qualities. The removable lining 49 1s tted within the main'sections of the drum and this lining is preferably of hard steel so as to resist the wear placed upon the same by the use of the apparatus as will be readily understood. The meeting edges of this lining are beveled as clearly shown in Figs. 2 and 4 so that they may meet along the central seam of the drum, and the driving ring 27 is formed with an inner shoulder 50 parallel with the outer shoulder 32 thereof against which the outer edge of the lining membermay rest as shown. By this construction the use of fastening bolts or screws to retain the lining in place is rendered un# necessary as the lining will be firmly held between the shoulders 50 of the driving rings adjacent the opposite ends of the drum and when it is necessary to renew the lining, the worn lining may be readily removed and new lining inserted through the wider ends 1 of the drum sections or members.
Within the drum are loosely mounted the crushing cones or rollers 51 having their widerv ends or faces serrated, as indicated at 52, and these cones or rollers have a taper somewhat greater than the taper of the drum so that when the rollers rest upon the bottom ofthe drum their wider ends or faces will fall away from each other somewhat, as clearly shown in Figs. 2 and 4, and be thereby adapted to catch and act upon the material within the drum so as yto thoroughly pulverize the same. The said cones or rollers are provided at the centers of their outer opposed faces or ends with cavities 53 to accommodate eyes 54 on the inner meeting ends of bolts 55 inserted axially through the cones and equipped on their outer ends with retaining nuts 56. The eyes 54 interengage, as clearly shown, so as to form a gimbal joint between the cones to permit the same. to roll or oscillate` relative to each other and the bores or passages formed through the cones for the reception of the bolts 55 are somewhat larger in diameter than the bolts so that a slight pla-y of the bolts will be permitted and the cones or rollers thereby enabled to partially accommodate unusually large particles which may the drum. This opening 57 will be utilized when the device is employed as shown in Figs. 1 and 2, this illustrated arrangement being that utilized when the device is to treat broken enamell ware or other refuse of jewelry factories or similar establishment. When treating such material it is desirable that no particles be permitted to escape until the thoroughly pulverized matter has been closely examined and for this reason l comterial will also Work into the space between A the serrated faces of the cones and will he thereby thoroughly p'ulverized so that the gold, silver and other metals or valuable particles will be separated from the less valuable particles and the pulverized material may be subsequently screened or otherwise treated to separate the valuable from the valueless elements.
My apparatus may be used in the practice of crushing as just described or may be used in the practice of the wet process'of separation which is more generally practiced. at brass foundries and similar establishments. ln this instance the imperforate head 37, shown in Figs. 1 and 2, is replaced by a head 62 similar in all respects to the head 37 except that it is providedI 'with a central opening, as indicated at 63, anda water supply pipe 64, said pipe being litt-ed with a valve (not shown) to control the supply in the said opening. The cap 42 is removed andthe material to be treated is then placed in the drum and the drum rotated after water has been caused to flow through the pipe 64: The material within the drum will now be crushed and pulverized in the same manner as the material' treated in the arrangement of the drum illustrated in Figs. 1 and 2 and before described, and light waste particles will be carried off through the mouth piece 39 by the water or other liquid flowing through the drum, the larger pieces of material sinking to and being collected at the bottom ofv the drum beneath the rollers While the smaller particles otmetal will be Washed into the angle formed between the outer flared portion of the mouth piece and the inner tubular memberd of the same. The said valuable small particles of metal will be consequently prevented from escaping so that the desired separation and reclamation of the metal will be readily and efectually ac-` complished.
ln treating ore at the mine, or previous to the treatment of the material in the reducing furnace, the mouth piece' 39is` removed from the left end of the drum and then secured at the right end as a substitute for the head 37 or the head 62, this arrangement being shown in Fig. 3. To the left end of the drum I then secure a tubular screen 65 after which the drum is rotated as before, the ore being fed in through themouth piece 39 and passing out through the screen 65 which revolves with the drum and separates the material as will be readily understood by thosev skilled in theJl art. The screen is shown in the drawings secured to the terminal member 33 but this particular arrangement may be varied without departing from the invention.
It will be readily seen from .the foregoing description taken in connection with the accompanying drawings that I have provided a crusher which may bc used in practising both wet and dry processes of pulverizing and which will operate efliciently without the application of high power thereto. As the drum is driven through smooth rollers by frictional engagen'lent the application of low horse power .will prove suiicient to-rotate the drum and accomplish -the work. The crushing rollers will have considerable movement relative to each other so that they will no-t only ride upon the material to crush the same but will also catch the material and grind it between their opposed faces. The machine is designed particularly for use in large brass foundries and similar works where there is an enormous amount of foundry ashes, skimmings, slag, sweepings,
etc., containing metal to be reclaimed, and
will rapidly and thoroughly crush all material placed within the-drum.
By forming the driving ring integral with the inner main sections of the drum l positively and effectually prevent the said rings from working loose on the drum so that the operation will be positive and certain throughout the life of the machine. Furthernore, by providing the terminal members of sections of the drum, l may utilize the opening at the end of leither main secltion to insert or remove the crushing vrollers when such operation is necessary and consequent-ly avoid disassembling the entire machine in order to repair or renew the crushing rollers. The provision of the inner tubular portion of the mouth piece is particularly advantageous as this element constitutes a base' or clamping point to facilitate the securing of the closure or cap within the mouth piece and also vconstitutes a trap to catch small valuable particles which would be otherwise washed out of the drum and lost- Particular attention is also invited to the formation of the main supportingrk frame in one integral structure as the separation and dropping apart of the frame heretofore occasioned by the `vibration or yielding of the apparatus in its operation is thereby overcome. The longitudinal webs or flanges on the inner faces of the side mem-` bers of the frame serve to stiifen the same so thatl buckling thereof will not occur and the transverse braces or webs at the, ends of the side members efectually prevent spreading apart of said members under the Weight of the drum and the crushing rollers t-herein. It will furthermore be noted that the driving elements are supported at the center of one end of the main frame so that the torsional strain on the said frame is equalized, and as the actuating train of gearing is inclosed the entrance of grit to the said 4gears is prevented and breaking of `the gear teeth or Wearing away of the gears from their centers is effectually overcome. The particular manner of supporting the driving pulleys is also advantageous as it supplies lubricant directly thereto and reduces the number of parts so that the space occupied by the complete. apparatus will not be excessive.
Having thus described my invention, what is claimed as new is:
1. In a crusher, a rotary drum comprising conical main sections having integral driving rings formed at their outer ends, said rings having plane radial faces and overhanging peripheri-es. conical terminal mem-. bers secured to the outer plane radial faces of said driving rings and extending outwardly therefrom, the annular edge of said terminal members being spaced inwardly from the peripheries of the driving rings and closures secured to and extending across the outer ends of said terminal members.
2. In a Crusher, a rotary drum comprising tapered sections secured together at their wider ends and having rings formed about their smaller ends, said rings having annular shoulders projecting within the sections, and removable linings fitted within the sections and having their inner ends abutting and their outer ends resting against the said shoulders.
3. In a Crusher, a rotary drum comprising conical sections secured together at their meet-ing ends and having driving rings vformed integrally about their outer ends,
forming a retaining pocket with the walls of the same.
5. In a crusher, the combination of a rotary drum, a mouth piece having oppositely flared ends and having one end Secured to the end of the drum, a cap fitted in the outer end of the mouth piece, a tubular member rigid with the mouth piece within the inner end of the same, hooks carried by the cap and adapted to engage the edge of said tubular member.` and nuts mounted on the` outer ends of said hooks and adapted to be turned home against the cap.
In testimony whereof I affix in presence of two witnesses.
