Application filed May 28, 1902.
Serial No. 109.259. (No model.)
To a/ZZ whom, it myconcerm Beit known that I, KIRKS. BLANCHARD, of Syracuse, in the county of Onondaga, in the State of NewYrk,have invented new and useful Improvements in 4]t"resses,.o f .which the following, taken in connection with the'ac companying drawings, is afull, clear, and exact description,
This invention relates to improvements in presses of the class set forth in my former application, Serial No. 94,668, tiled February 18,1902, except that my present device is arranged in an upright position.
One of the primary objects dilering from the purposes of my former application above referred to is to provide an intermittentlymovable bedv upon which the material is com; pressed and successively removed from beneath the compression mechanism after each successive operatiom'the movable bed and the compression mechanism being synchronized to effect this intermittent and successive movement from a primary moving power. l
y Another object is to provide means for rel; y moving the adhering material from the mov.; able bed after having discharged the`comj` pressed material. i;
A further object is to feed the material by gravity to the movable bed and to provide the receptacle for the material to be compressed with suitable inlet and ldischarge.openingsV and with' closures for said openings connected to the primary moving power in such manner as to open and close automatically at regular predetermined intervals for purposes hereinafter described, and a further object is to provide means whereby bodies of unequal compressibility may be subjected to a uniform pressure for producing cakes or compact bodies of substantially uniform density, but of varying thicknesses, especially where the materials to be pressed are of varying densities in their initial state, this compression being effected by positive means without liability of impairing the utility orintegrity of the machine. i
To this end the invention consists in the combination, construction, and arrangement of the parts of a press, as hereinafter fully described, and pointed out in the claims.
Referring to the drawings, Figure 1 is a side elevation, partly broken away, of an upright,V
" the inlet-gate.

Apress embodying the various features of my invention. Fig. 2` is a front elevation, partly in section and partly broken away, of the device seeninlig.` l. Figs. 3 and 4 are sectional views taken,V respectively, ou lines 3 3 Fig. 4 is arface View of the cylinder and compression-box, showing particularly the means for raising and lowering Fig. 5 is a detail view of the means for agitating portions ot` the carrierbelt, and Fig. 6 is a perspective view of one of the detached links for carrying the slats or bed-pieces.
Similar reference characters indicate corresponding parts in all the views.
VIn thepdrawings I have shown an upright frame 1, upon which is mounted an upright .receptacle 2 for receiving the material to be compressed, horizontally-moving endless bed W3, forming the bottom wall of the receptacle,
an upright cylinder 4, verticallymovable pistous 5 and 6, anda body of liquid 7 withinA the cylinder 4, a compressor-head 8, connected to oneof the pistons, as' thelower piston 6, and forming the upper wall of the recep; tacle 2, and suitable power transmitting mechanism connected to a primary mover 9 `for transmitting motion to the endlessbed 3, pistons 5 and 6, and various other moving parts of the machine, hereinafter more fully -The frame 1 may be of any desired size, form, or constructionadapted for the purposes for which my press is used, and con sists, essentially, of upright front and rear standards lO and 1l and intermediate bars 12, said standards and bars being suitably united to each other by cross-bars 12. The receptacle 2 mayalso be of any desired form, size, or construction, dependingupon the quantityand form of the material to be compressed,
IOO
pressed automatically, I provide a chute or a hopper 16, having an inclined bottom wall discharging through the inlet-opening of the receptacle onto the movable bed 3 when the gate 14 is open.
The movable bed 3 preferably consists of an endless belt mounted upon drums orsprocketwheels 17, which are journaled upon the frame in a plane beneath the lower end of the receptacle 2, the upper section of the belt forming the movable bed or bottom wall for the receptacle. This belt is preferably made up of a series of transverse slats or bars arranged in proximity to each other and secured to special forms of links having annular anges 19 and 20, the flanges 19 receiving and supporting the several slats of the belt, and the flanges 2O travel in close proximity to the inner faces of the lower edges ot' the lengthwise walls of the receptacle.
Any form of link assembledin the form of an endless chain may be employed for supporting the slats, providing said links are formed With the flanges 2O or equivalent means for preventing the leakage or expression of the material at the endsof the slats,l
or rather at the longitudinal edges of the portions of the belt which are registered with the receptacle during the act of compression of the material.
I preferably employ two chain belts, one at each of the longitudinal edges of the receptacle, for supporting the opposite ends of the slats or endless bed proper, and in order to relieve the strain upon the chain belts and slats of the endless head I provide a transverse wall 2l beneath the lower end of the receptacle and immediately under the upper section of the belt, said wall forming a supplemental bottom of the receptacle and serves to hold the endless bed in position against the action of the compressor mechanism presently described.
The endless belt is connected to a suitable prime moving power to move in the direction indicated by the arrow Qc, Fig. 2-that is, from the closed side of the receptacle opposite the outlet-opening toward said outlet-openingfor the purpose of conveying the compressed material from the receptacle after each successive movement of the compressing mechanism, the gate or closure 15 being open during the movement of the bed. In order to maintain the belt in a substantial taut position, I usually mount one of the drums upon a moving bearing, as 23, (seen at the left hand at Fig. 2,) said bearing being normally forced outwardly for tensioning the belt by a spring 24.
The cylinder 4 and pistons 5 and (3 and also the liquid body 7 are very similar to the corresponding parts of the former application referred to, and it will therefore be unnecessary to enter into a detail description, it being sufficient to say that the pistons 5 and 6 are movable independently of each other and that the body'of the liquid serves as a means 'faenas for transmitting motion during the act of contipression from the piston 5 to the piston 6 and thence to the movable wall 8.
The movement of the piston 5 is positivo and is required to move a certain distance at each operation, while the movement of the piston 6 is variable, and in order to relieve any excessive pressure between the two pistons beyond the predetermined degree I provide a conduit 25, leading from the liquidchamber of the cylinder, and also provide a reservoir 26, connected to said conduit, for receiving the liquid, and thereby relieving such excessive pressure ofthe piston 5, this portion of my device being also similar to that set forth in my former application, and it is therefore thought to be unnecessary 'to further illustrate or describe the same.
The means for moving the piston 5 to its operative position in the act of compressing the material consists, primarily, of a cam 27 and a rock-arm 2S, having a rolling engagement with each other, the cam 27 being actuated by a train of gearing 29, driven from the prime mover 9, and the rock-arm 28 is normally held in engagement with a stop-face 30 by means of a weighted arm 31, provided on said rock-arm. v.
The means for returning the pistons and rock-arm to their normal or starting position after each compression consists of a weight 32 and a link 33, the weight 32 being connected by a cable 34 to an arm 35 on the piston 5, and the link 32 is connected at one end to the head S, its other end beingloosely connected to the arm 35 in such manner that the piston 5 may move inwardly independent of the head 8; but when the piston 5 is withdrawn a certain distance by weight 32 and cord 34 similar movement is imparted by the link 33 to the head S, so that both pistons move simultaneously for the greater part of their distance to the starting position.
It is necessary in this class of machines to operate all of the movingparts automatically, and it therefore becomes necessary to synchronize the movement of the said parts one with the otherthat is, during each successive compression or operation of the pistons the endless bed is at rest, and immediately upon the return of the pistons to the starting position the endless bed is caused to move a sufficient distance to carry the compressed material outwardly beyond the outlet-opening. .lust previous to or substantially coincident with the return movement of the pistons and just before the movementof the endless bed in the act of discharging the compressed material the gate 15 is open, it being understood that this gate is closed during the operation of compressing the material. In order to effect the upward movement ot the pistons to the endless bed and gate l5, I provide one of the gears of the train, as the larger gear, which may be designated by the numeral 35', with a cam 36, which during the revolution of the gear 35 in the direction of llO ' the arrow @l operates a plunger-rod 37, which in turn rocks a lever 38 and elevates the C'ate V15. The cam 27 is also secured to the shaft of the gear 35', and these two cams are so timed that immediately upon the release or disengagement of the cam 27 with the bearing-face of the arm 28 the advancing face of the cam 36 engages the roller end of the plunger-rod 37 and immediately elevates the gate 15, thus opening the outlet for the free discharge of the compressed material.
The means for moving the endless bed immediately after the elevation of the gate 15 is here shown as consisting of a gear 38', a clutch 39, and au operating-lever 40, the gear 38 being loose upon ashaft or spindle 41, driven from the shaft of the prime mover` 9 by a sprocket-chain42, and the clutch 39 being secured to the shaft to rotate therewith, and it is thus apparent that the shaft 41 is always rotating and that the gear 38', being loose on the shaft, is idle except when engaged by the clutch 39. This clutch is operated' automatically by means of the lever 40 and the rock-arm 38, said lever 40 having an extension projecting into the path of the upwardly-moving end of the rock-arm' 38 as the gate 15 is elevated. It will thus be seen that the rock-arm 38, elevating the gate` 15, also operates the lever 40 to engage the clutch 39 with the gear 38, thereby revolving said gear 38' and the endless bed 3, which is connected to said gear by another gear 44 on the shaft of the drum 17.
Immediately after. the discharge of the compressed material from the receptacle 1 by ginning of the operation of compression. I-
therefore provide the gear 35 with an additional cam 43, which is connected to open the gate 14 im mediatelyiafter the gate 15i`s closed and to again close the gate just before the initial movement of the pistons 5 and (l. It will be apparent from the foregoing description and the accompanying drawings .that these several cams 27, 36,-and 43 control the operation of the pistons 5 and 6 and gates 14 and 15, as well as the movable bed 3, and that although I have shown a .speciiic'mechanism for synchronizing these several Inovements it will be evident that other mechanisms may be employed with equal efiiciency.
The means cooperating with the cam43 for opening and closing theinlet-gate 14 preferably consists ot a vertically-reciprocating rod 44 and a lever 45, having one endconnected After the operation of compressing the material upon the endless belt it is desirable to provide some means for removing the material which may adhere to the lower face of the compressor-head, and I therefore provide said head with a shaker-frame 49, similar to that set forth in my former application `previously referred to, said shaker-frame being mounted upon reciprocatory rods 49', movable in `the head 8 against the action of the springs 49. The means for reciprocating these rods .49" is here shown as consisting of a rack and pinion, the shaft of the pinion being provided with rotary arms 49', which are alined with the upper ends of the rods 49" and successively engage the upper ends of said rods as the pinion is rotated along its rack by the vertical movement of the plunger G, as clearly shown in Fig. 3. It is evident, however, that `other means may be employed for reciprocating the shaker-frame 49, as I believe this part of my invention to be entirely new.
In devices of this character portions of the material adhere to the belt or bed after the discharge of the bulk of the compressed body therefrom, and in order to remove this adher-` ing material I provide one or more beaters 50 and 5l, the beater 50 consisting of abarmounted upon one end of the bell-crank 52,the other arm of said bell-crank being adapted to trail upon theflinks of one of the chains', and the beater 51 preferably consists of a brush, which is rotated against the surface of the lower section of the bed by asuitable belt 54, connected to a sprocket-wheel 55 on the shaft of the drum 17 at the discharge end of the endless bed. Owing to the fact that one ofthearms of the bell-crank` trails upon the chain, it is rocked by each cross-bar of the several links 'of the chain and causes the bar 50 to strike `and the advancing end of the cam 27 is just on the point of engaging the connecting-rod 28. As the cam 27 continues to move in rolling contact with the upper end face of the rod 28 the piston 5 is thereby moved toward the upper portion of the endless bed 3 and through the medium of the body of `liquid 7 produces a similar movement upon the piston 6, which operation compresses the `material in the receptacle 2 upon the adjacent portion of theuendless bed 3, which` duringthis IOO IIO
its movement it is automatically returned to its normal position by the weight 32 and cord 34 and simultaneously draws the piston 6 to its normal up position through the medium ofthe link 33. Immediately upon the return of the piston 6 after each compression the gate is automatically opened by the cam 36, rod 37, and lever 38, and as soon as this `gate is sufficiently elevated the clutch 4l is operated by the levers 38 and 40 to rotate the endless bed for the purpose of carrying the compressed cake of material thereon through the outlet-opening of the receptacle 2 beyond the gate 15. As soon as this operation is completed the receptacle is free to receive additional material to be compressed, and the inlet-gate is immediately opened through the medium of the cam 43, rod 44, and lever 45, and the material gravitates from the hopper 16 onto the portion of the bed 3 within the receptacle, it being understood that just before the opening of the inlet-gate 14 the outlet-gate 15 closes, and the movement ofthe endless bed 3 ceases and is at rest during the feeding of the material to be pressed into the receptacle 2. While the head 8 is being elevated after Y each compression the shakerframe 49 is agitated by the arms 49"', and when the compressed material is conveyed out of the receptacle by the bed 3 the beaters 50 are actuated to loosen any of the material adhering to the bed.
The operation of my invention will now be readily understood upon reference to the foregoing description and the accompanying d rawings.
I-Iaving thus described my invention, what I claim, and desire to secure by Letters Patent, is-
