To on whom it may concern: I
Be it known that I,-IsAAc BROOME, a citizen of the United States, residing at Trenton,
- in the county of' Mercer and State of New a rotary machine that will achieve t is purr scending pose without the rigidity common to such machines, the mechanism of my invention being so arranged that its operations are elastic. This I attain, firstly, by providing a direct parallel ressure on the faces. of movable dies place in chambers in a rotating cylinder by means of oscillating plungers p aced in the peri hery of rotating disks. Secondly, by the p ungers following the deand changing position of the dies and maintaining their dlrect line of pressure by means of uides during the rotary movement. Thir ly, by lapping the periphery of the disks over the periphery of the cylinder to the depth required for pressure, as illus trated in the accompanying drawings and specifications.
- Figure 1, is a side elevation of the machine with frame and casing omitted, displaying its princi al parts. Fig. 2, is a vertical cross section 0 the same, with frame, bearings and arts more full indicated. Fig. 3, shows in urther detail t e working parts of the cylinder, disks, plungers cams, lift-up and oiler, and their situation during operation. Fig. 4, shows in perspective view a detached die with arms, levers and exterior springs. Fig. 5, a sectional view of the oiler. Fig.6, a detached box with arms, inside springs and lift-up. Fig. 7, a view of the plunger with its slides and turn-over.
Similar letters and figures refer 'to similar parts throughout. the several views.
The following is a description of my invention.
Briefly stated, it consists of a verticallyarranged rotating cylinder, or drum, containing dies arranged peripherally and operating radially downward by pressure upon their surfaces, and upwards to alevel with the peripheral face of the cylinder, the dies operatmg between partitions forming chambers, which are part of the cylinder, placed at con- 'venient intervals. The bottom of the champlunger, preferably termed the lift-up, which receives the pressure u on its ripper end,
placed'within the die. he so ca ed lift-up serving not only to receive the ressure on the material contained within t e die, but also, by means of cams, arms and springs attached to, or acti upon its lower'part operates within the die to eject the pressed material.
In conjunction with the rotating cylinder, or drum, rovided with chambers and having mova le dies set therein are verticall arranged rotating'ldisk plates of the same d1- ameter as the cy nder, placed so as to span and overlap the cylinder, that is to say, the disk plates and cylinder overlap each other to .the depth requisite to press the material within the dies. Between these disk lates, which are braced together and mounted upon a shaft, are placed oscillating plungers pivoted by their arms at the eriphery of the disks. These press upon the aces of the spring supported dies contained in the cylinder causing them to descend in their chambers to the given depth of pressure, after which the pressing plun ers are guided by means of a fixed cam to e set in position to meet the parallel faces of the dies as the disks and cylinder rotate together. Mainly, this is the operation achieved in conjunction with several requisite and indispensable mechanical parts to successfully complete and func tion this system of obtaining an elastic pressure and to avoid the rigidity common in the action of this class of machines.
Further details ofthe invention and the relation and function of the several adjunctive parts are set forth and explained in the following specifications.
Figs. 1 and 2. (A) represents a vertically arranged rotating cylinder, or drum, radially partitioned into a series of boxes, or chambers geripherally arranged within the cylinder. etween these are open spaces covered by the peripheral face of the cylinder. the chambers are fitted dies (M) sup orted to the face of the cylinder by springs underheath them, permitting a radial movement of the dies wit in their chambers by pressure upon the springs (T). (Figs. 1,2-and 3). Lat
eral arms (J) project from the dies (M) andpass through a slot (E) in the sides of the cylinder (A). Levers (0) act exteriorl upon the arms (J) to press upward the dies (ill) by the tension 0 springs (T) upon the pivotal rods of Within bers constitutes the bearing surface for the the levers (O) placed transversely in the open spaces of the cylinder (A). (Fig. 4.)
Fitted within the open-dies (M) (Fig. 6)
and forming the bottom of the same are plungers, or lifts-up (Q) seated by a flange upon their stems on the bottom of the chambers in the cylinder (A) the lower parts of their stems passing through apertures in the bottom of the chambers permitting the stems to be raised or lowered in the dies (M) by the antifriction rollers in the ends as they rotate with the cylinder (A) around the face of a fixed cam. (P).
In addition to the action of the cam (P) upon the end of the lift-up (Q) are lateral arms (N), provided with anti-friction rollers. Said arms N extend from the lift-up (Q) through the slots (E) in the ends of the c linder (A) and fit into the groove of the ed cams (P') placed adjacent the sides of the cylinder (A) and attached to the frame of the machine. Said arms (N) operate the lift-up upwards and downwards conjointly with the cam (P) byfollowing the' cam groove in (P') as the cylinder (A) rotates. Perfect bearing upon the bottom of the chamber M is secured by the. springs (T) underneath the die (M) ressin upon the flange on the stem of the lift-up ((5). (Figs. 3 and 6.)
Disk plates (B) of the same diameters as the cylinder (A) are mounted upon a shaft and separated so that their peripheries will span and lap .over the face of the cylinder (A). Between the disks (B) are placed transversely a series of oscillating plungers (U) pivoted b their arms to the periphery of the disks (B their faces exactly parallel with the ivotal centers. (See Fig. 7.) The faces 0 these plungers (U) contact with the faces of the dies (M) by the simultaneous rotary movement of disks (B) and cylinder (A) and press the dies (M) downwards upon the springs (T) and lift-up (Q) to the depth of the overlap of the diameters of the (llSkS and cylinder.
It is evident that to accomplish the parallel meeting ofthe faces of the dies (M) with the faces of the plungers (U) at a point distant from a line connecting the shafts of the disks and cylinder, the plungers must assume a chordal position upon the disks (B) at the oint of contact, which positionis chan e by the rotating movement to a direct e with the center of the cylinder and disks, and again to a reversed chordal position upon the disks after the central line of pressure is past, the plungers following the radius of the cylinder. To securely control this movement of the oscillating plungers (U) slotted projections, or guides (Z) are placed upon the arms of the plungers (U) which engage in their slots projections (Z) placed on the exterior sides of the cylinder (A) lparallel with its radius, and guide the osc' ating motion of the plungers (U) dur- (A) am ing pressure upon the dies (M) in arallel line with the radius of the cylinder (K).
Upon the pivotal shaft of the lplunger (U) which extends-through the dis plate (B), at its peripheral line, is fixed a crank (D) provided with a wrist 1pin (X) (Figs. 2, 3 and 7). At the centra line of pressure of the plungers (U) upon the dies (M) the wrist in (X) enters the groove of a fixed cam attached to the frame of the machine, guiding by its control of the crank (D) the positionof the face of theplunger (U) to receive during its passage the cleansing and lubricating arms of the rotating oiler (F), (Fig. 5) after which the plunger(U) is set by the cam (Y), acting upon the wrist pin (X), into its chordal osition upon the disks (B) to meet square y the face of the die (M) during rotation.
To maintain the plungers (U) in position during the rotating movement of the disks, a series of notched latch gri s (W) are Bplaced upon the inner sides of t e disks and ivoted, near the periphery, to the disks. he latches (W) grip in their notches the top of the plungers u (U) at their temporary chordal position on the disks and retain them by pressure of the springs (T) also attached to the disks, upon the upper edges of the latch grips (W). At the moment of contact of the plungers (U) with the dies (M) the slots of the slides (Z) engage with the projections (Z) and ease the plungers (U) out of the notches of the latch grips (W) permitting the plungers to be guided, during pressure, in a line with the cylindrical radius and their faces parallel with the faces of the movable dies (M).
A rotating oiler (Fig. 5) placed beneath the disks (B) is rovided with arms (F) pivoted upon'the en s of a cylinder (F) bearing trans verse bars between the arms parallel with the cylinder to which are attached springs (F) that extend outwardly to and underneath the bars of the arms (F) and furnish elastic pressure, while rotating, upon the faces of the lungers (U) to cleanse and oil them, the 'aces of the plungers being guided into proper position to receive the action of the lubricating arms of the oiler by means of the crank (D) and cam (Y).
To cleanse and lubricate the peripheral face of the cylinder (A) and the face of the lift-up (Q) a rotating brush oiler (G) is attached to the frame of the machine in front of the cylinder (A);
A hopper (C), placed above the cylinder maintained in osition by a casing, or box, fixed to the ta 1e of the machine, feeds material into the dies (M) contained in and maintained level with the face of the cylinder (A). The lower end of the be per (C) is curved to fit the peripheral face 0 the cylinder (A) and is prevented from resting on the cylinder by set screws ((3') attached to the sides of the hopper and at the upper end of its receiving box. The material so fed to the dies (M) after undergoing pressure by the plungers (U) is depositedupon the carrier elt (I) operated by' the pulley (H).
Details of scrapers, brushes and surface cleaning arrangements common to all machines are consldered unnecessary, not being vital to my invention.
