To all whom it may concern:

Be it known that I, IRA FonEMAN, a citizen' of the United States, residing at Long Beach, in the county of LosAhgelesand State of California, have invented certain new and useful Improvements'm Materlal- Compressing, Machines, of which the following is a specification. h A

v This invention relatesito improvements in material compressing machines and particularly of that type adapted for receiving Inaterials. of various kinds that it Jin ay bedesired to compress and form into compact body, mass, stick or bar, the composite piece or'stick thus formed being divided into suitable lengths and bound by a strong holding 7 much work upon the material compressing portions of the mechanism. v V r 7 It is an object of'thejinvention to provide a machine in which the mechanis'm "for controlling the breaking and twisting of the sticksformed, is driven inconjunetion with the material compressing plungermechanism, but without placing strain or twisting It is a'further object ,ofthe invention to provide, a machine of the typetmentioned in which cables are employedforoperating the twisting mechanism in twisting the binding wires between the dividedz sections o,f ;the material, in proper timed relationto the other parts of. the machine. I

7 It is. a further object of hej invention to provide. such a machine withaouickacting material separating or breaking inechanism, thus insuring .a. quick .separationlofathe parts of the compressed .materi:j1 l "as...;t'he twisting operation begins, for fastening-"the bindingwires in place, 1;;

Fig. 19 is a fragmentary detail view of a portion of a trip rod mechanism and showing a spring thereby.

The details and features of the invention pressed cam block carried will now be more specifically described reference being had to the. accompanying drawings, in which 10 indicates the frame of the machine, the central portion of said frame being provided with a platform 11 adapted to carry aforming die 12 and a receiving hopper 13. The upper portion of thefraine 10 extends considerably above the platform 11 and supportsbearings for a shaft 14, which carries a gear wheel 15 and a crank disk 16. Said crank disk 16 is provided with a wrist pin 17 which'e ngages a pitman 18 for operating it as the shaft 14 is rotated by the gear 15. The lower end of the pitman18 is connected witha plunger head 19 moving in guides 20 upon the frame 10 and carrying a compressing plunger 21 which is adapted to force materials to be compressed, into the hopper l3, and the die member 12. The gear 15 is usually driven '7 by means of a pinion 22, meshing therewith and carried by a transverse power shaft 23, which is JOUIDZLlGCl 1n suitable bearings upon the frame 10. A pulley 24 is mounted upon the shaft 23 and may be connected by belting 25with anysuitable source of power not illustrated. The said pulley 24 preferably runs freely upon the shaft 23 and may be connected therewith when the machine is I to be operated, by the manipulationof a clutch, usually of the type illustrated in .F 1, of the drawings. Such clutch usually comprisesa friction disk 26 adapted to bear upon one side'of the pulley 24. The said disk and an adjacent collar 27 are splined to the shaft 23and operating levers 23 are carried by said collar and bear against the said disk-26. The outer ends of thelevers 28 bear upon said. disk through adjustable screws 29, while the inner ends engage and are adapted to be separated by, a cone. sleeve 30 loosely :mountedupon the shaft 23. A hand lever 31' pivoted upon the frame and having a yoke portion 32, engaging studs 33 carried by the said.collar.30, is provided for operating said cone. It will be readily understood that when the lever 31 is forced inwardly to force the cone 30 between the levers 28, the friction clutch 26 will be 'broughttightly against the pulley 24, whereby the said disk will beturned with the pulley and the movement thereof be imparted to the shaft 23.

The platform 11 is formed with an opening thereinfor receiving the die member 12. Said die member is usually formed of two approximately semi-cylindrical sections 34 i and 35, the'upper ends of which are formed with. overhanging flanges 36, and 37, which rest upon the upper surface of the platform 11. ,The dissection 34is usually immovably held in position being secured to the I platform 11 by one or more bolts 38. The

other. section 35is so made as to rock slightly upon the edge 39, formed upon the platform 11. Such rocking action is valuable when thematerials compressed become too tightly wedged within the die and a. slight separation ofthe. die sections caused by the rocking of thesection 35 will relieve the extreme tightness of .the materials and permitthem to be pushed on through the die. The lower ends of the die sections are generally sup-' ported also, the section 34 resting against an abutmentfbolt 40 carrying abutment nuts 41, said bolt'being 'fixed upon the frame of the machine. The lowerend of theother die section 35, preferably rests against an adjust-able abutmentbolt 42 andvthe outer end The upper formed in the edges" of said die section flanges. t-ions together at the top but permits of the rocking of the-section 35 in expanding or contracting the die. I

This connection holds the die sec- The die sections are usually formed with lining sections 46 and 47 the inner surfaces of which form an approximately cylindrical passage large enough'to receive the plunger 21. The hopper 13 is mounted upon the upper ends of the the sections 34 and 35 and the lower contracted end thereofis made to just fit over the opening in the die lining sections 46 and 47.

The loose materials are continuously forced into the die at each reciprocation of the plunger 21 and are pushed downwardly th r'ough said"clieforf ing a continumis' sticl -''ofcompressed materials. These materials forming the s'tick being'usually sawdust,

inf'the compressed stick as otherwise-the beneath the said binding means when placed "in a fire thus permittingtoorapid disinte- "gration' of. the stick to form agoo'd fuel. This difficulty is obviated by the use of knife pieces48 and 49 mounted oppositefeach other *in "slots formed upon the inners-urfaces of Y'the lining sect-ions 46 and47. ljAs-the material is forced throughthe dieftheknife pieces will form deep kerfs in the opposite sides-of the compressed stick'as indicated at 50jin Fig. 18 of-the drawing.

Itlis" an important featuitebf this invention that the breaking of thestickand the separation of thesections thereof, is accomplished 'q'uiclrl'y' so that the 'wire' cuttingiknife or mechanism may be thrust quickly between the sectionsfor clipping" the twisted wires. iThef mechanism for accomplishing these purposes forms a novel portion ,of this 'in- 'vention.

Said lower platform is supported below the platform ll and about halfway'betwee'n the same and' th'e base of the machine. Between the rods '58 -a'nd the cylinder 55, antifriction rollers '63 are loosely mounted on the trunnions 57 and the'bifur'cated ends 64 of a yoke 65, engage'said rollers and operate to raise and lower thecylinder 55." T hesidebars of said yoke lever 65 are pivotally mo'untedon platform 62. The said yoke 65 is provided with anoperatlng projection portion 67 havng a socket 68 in'the end thereof; adapted to extend into the parts'of, and fit up'on fulcrum brackets 66 which rise fromthesaid and receive'a yoke operating stud or projec- 'tion' 69 which-is carriecl by a reciprocatingf member or rod 70, The said stu'd'69' 'is *usu'ally provided with an antifriction roller '71 as clearly shown in Fig. '1l.= Theproj'ec- 'tion 67 of the yoke is provided with a' heel "portion 72 which is struck'by the roller 71 tof fcause the'lifting and supporting of the cylinder 55 by said yoke 65. The said pro-. j'ectron 67 is also provided with an elongated guidingtoe portion 73,' which insures" the proper leading of the roller 71 to the socket 68 when it approaches the outer end of the yoke to depress the same for twisting the "cylinder 55. The movement of thestud 69 with the reciprocating member'or rod 70 "will be hereinafter more fully described.

The lower end ofthe cylinder 55 is prowided with a reduced cylindrical extension 74, the lower end'offwhich engagesa guide bearing 'T5formed in the end of a bracket 76 carried by the base of the machine; The upper larger portion of the cylinder 55 has mounted within it semicylindrical' sections 77- provided With supporting flanges 78 at was -i1 to their upper edges. The said sections 37 do not quite fillthe interior of the cylinder 55 and may thus be slightly-spread" when the-stick of compressed materials "is' 'forced throughthem'.

Y i for ed vented-from turning with respect to 1 Loosely mounted upon the lower reduced cylindrical portion 74 of the twisting cylinder is an actuating sleeve 83, the said sleeve being limited against upward movement by the shoulder 8% formed at the lower end of the larger portion of said cylinder.

recess 86 therein for accommodating a ratchet member 87 which is rigidly secured to the cylinder. Said sleeve is also provided with outwardly projecting portions 88 opposite said ratchet 87, in which are mounted pawls 89 which engage the teeth of said ratchet 87. Springs 90 bear upon said pawls for pressing them continuously against the said ratchet. The structure is thus such that when the sleeve 83 is turned in one direction the pawls will catch upon the teeth upon the ratchet 87 and turn the same together with the cylinder 55. When the sleeve is reversed and turned in the opposite direction the pawls will merely slip over the teeth and not turn the said cylinder. In this way the cylinder only turns in a direction proper for twisting'the severed portion or the stick of compressed materials, after each breaking ofi' of a stick section by the lowering of the cylinder. The bearing portion 75 of the bracket 76 is arranged so that it will not interfere with the movement of the cylinder 55 downwardly to the extent it is carried by the action of the yoke member 65, the downward movement of the inner end there of being limited by the platform 62. The sleeve 83 is rotated first in one direction and then the other by a. suitable cable mechanism operated by the movement of the reciprocating rod 7 0 and the operation of the said rod will now be described first.

The rod is preferably a rectangular bar, generally square in cross section, the upper end thereof engaging a guide bearing at 91 projecting from the upper part of the frame 10, while the lower portion of said rod passes through guide bearings 92 and 93 ,upon the platform 62 .and the base of the frame vl0 respectively The said rod is reciprocated at suitable intervals by means of a cross head 94 which slides in a vertical 'guideway 95 mounted upon the upper part :of the machine frame 10. The said cross head 94 is pivotally connected with a pitman 96 and the said pitman has a bearing upon a wrist pin 97 upon a gear wheel 98. The said gear wheel 98 is carried by a short shaft 99 which is journaled in a bearing 100 at the upper portion of the frame 10. The gear 98 meshes with the gear teeth upon the periphery of the disk 16 whereby it receives its power for driving the cross head 94. Projecting from the cross head 91 is an annular'arm 101 which extends around two sides of the rod 70 as clearlyshown in Flgs. 3, 4: and 9. At a proper point upon the rods 70 is secured an abutment block ment of a trip piece 103 which normally 'oocupies space in a depression 104 upon one side of the rod 70. The said trip pieceis pivotally connected with the rod 70 by means of links 105 and is normally locked by a latchmember 106 which is pivotally mounted on the oppositeside of the rod 70 from the trip piece 103. As indicated in dotted lines in Fig. 4 the said latch piece or member 106 is approximately s shaped, its

upper end curving outwardly so as to en-;

gage an aperture 107 in an arm 108 which extends laterally from one edge of said trip piece 103 across the rod 70. Whenlocked by the said latch member 106 the trip piece 103 will be held in the said recess 10%, so that the arm 101 may move back and forth over the same, without liftingthe rod 70. A spring 109 connecting the free end of the arm 108 with the rod 70 normally tends to throw the trip piece 103 outwardlyand into the path of the said arm 101,so that the said arm will engage the lower end of said trip piece and lift the rod'70. The lower end of the latch member 106 is curved in the opposite direction from the upper end and is engaged by a spring 110, so thatthe said latch piece will remain in looking engagement with the arm 108, until it is positively moved-against the action of thespring 110. The said latch piece is not thus moved however until the stick of compressed materials has attained a proper length and at e that time it is positively moved by the action of a trip rod 111, which is pivotally connected at its lower end to a trip lever 112, pivotally mounted at 113 upon the under side of the platform 11. One end of the trip lever 112 is curved as at 114, and is adapted to'be struck by studs 115 projecting from one side of the serrated wheel 54. The said studs 115 will operate the trip lever 112 at suitable intervalsto draw the trip rod 111 downwardly and bring a cam block 116 carried thereby, into contact with the lower end of the latch member 106. The cam block is pivoted to the trip rod 111 at 117 and is normally held against a limiting pin 118 by a spring 119. When the trip rod 111 is lowered a cam 'face 120 will move the lower end of the latch member 106, sothat the upper end will release" the trip' piece -lQir'ilndf permit the spring 109 to zthrow itfo'ut wardly. The rod 70 will then'rbekrcarried upwardly by the nextupward movementof iugflby means of a spring pressed bolt .1122

The said roller 155' insures a smooth reentry of the roller 151 into the lower end of the cam path 152 as the rod 7 0" descends. The cutting device will thus only be operated when the rod 70 is raised and lowered for the separation of thestick of material and the twisting of the wires. a

readily understood from the above description that a general reference to the operation in a connected form will probably be suflicient at this point. The machine is set in' operation by the throwing of the clutch disk 26. The plunger 21 will be caused to reciprocatecontinuously by the rotation of the crank disk 16 and the particles to be compressed such as sawdust, shavings, chips and the like that are fed into the hopper 13 I will be continuously compressed to lengthen the stick being formed in the die. Thematerials thus compressed will be forced between the wires 51 which havebeen twisted together at the bottom and as the stick passes the serrated wheel 54 it will be turned thereby. When a stick of suliicient length has been produced, the said wheel 54: will trip the lever 112 causing the unlatchingagain, the roller 71, which has left the socket 68, will descend and come into engagement with" the heel portion 72, depressing the outer end of the yoke 65, and causing the inner end thereof to raise the twisting member to its position adjacent to the die for receiving the end of the stick of compressed materials as it is lengthened and forced downwardly. The socket 68 is deep enough to allow for the rocking of the yoke without binding upon or forcing the roller 71 and its stud 69 outwardly. The cutting mechanism willhave been withdrawn from between the The operation of all the parts i thus entirely automatic when the machine is running. The completed sticks 'with the wires twlstedat their ends, will force each other out of the lower end of the twistingv member in succession;

While the machine has been. shown with only one compressing'plunger and cooperating parts, it will be evident that the parts 'may beduplicated upon the other side of themachineframe and run from the same ,7

start 14", for doubling or further increasing The operation ofthe machine will be so the capacity of the'machine withoutdeparting in the least from the spirit and scope'of through the die and twister to perform, and I that the pitman 96 and the cross head 94 by actuating the rod 90 accomplishesallthe work of breaking the stick, twisting the wires and cutting the same. The strain of operation is thus muchmore evenly dis tributed through the parts of the machine than in former mechanisms of this type and the machine itself is more simple and less likely to get out of order than wood compressing machines of this kind that have been heretofore used. It will beevident of course that the minor details of construction, of the parts of the machine may be considerably varied within the scope of the invention. 1 I
