ANDREAS SENDLEIN, OF ST. LOUIS, MISSOURI.

MOLDING A'ND COMPRESSING MACHINE.

SPECIFICATION forming part of Letters Patent No. 711,883, dated October 21,1902.

Application filed March 15, 1902. Serial No. 98,L17. (No model- To all whom it may concern:

Be it known that I, ANDREAS SENDLEIN, a citizen of the United States, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in Molding and Compressing Machines, of which the fol lowing is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention has relation to improvements in molding and compressing machines; and it consists in the novel arrangement and com bination of parts more fully set forth in the specification and pointed out in the claims.

In the drawings, Figure 1 is a front elevation of the machine. Fig. 2 is a rear elevation thereof. Fig. 3 is an elevation of one side thereof. Fig. 4 is an elevation of the opposite side. Fig. 5 is a part-sectional elevation showing the cams operating the compressing-plungers. Fig. 6 is a part-sectional elevation showing the cams operating the ejecting device, the feed-head, and the male portion or tongue of the die. Fig. 7 is an enlarged sectional front elevation showing the die and cooperating parts. Fig. Sis a View at right angles to Fig. 7. Fig. 9 is a horizontal section on line 9 9 of Fig. 7. Fig. 10 is a sectional enlarged detail (corresponding to the parts as shown,) showing the cut off piston andthe feed-head. Fig. 11 is a horizontal section on line 11 11 of Fig. 10. Fig.

12 is an elevation in detail showing cam operating the cut-off piston, the latter corresponding to its position in Fig. 3. Fig. 13 is a similar View showing the cut-off piston ele-' vated and the feed-head withdrawn, this position corresponding to that occupied by the parts in Fig. 6. Fig. 14 is a sectional detail showing the material operated on in the act of compression in the die and the feed-head withdrawn. Fig. 15 is a sectional detail on line 15 15 of Fig. 6. Fig. 16 is a section on line 16 16 of Fig. 6. Fig. 17 is a vertical section on line 17 17 of Fig. 3. Fig. 18 is a transverse section on line 18 18 of Fig. 7. Fig. 19 is a section on line 19 19 of Fig. 5. Fig. 20 is a view of the reverse face of the cam-disk shown in Fig. 6, illustrating the cam-surface which actuates the feed-head; and Fig. 21 is a detail showing the last position occupied by the component parts of the die previous to the removal of the compressed block by the ejector.

The present invention relates to a class of machines designed for molding and compressing into blocks suitable composition for use as a fire-kindler, the particular object of the invention here described being to produce a machine which shall operate on a maxim um number of blocks, one the product of which shall be uniform, one which shall be compact and positive, one which is simple in construction, one producing blocks of great compactness, one which is positive in action, and one possessing further and other advantages, better apparent from a detailed description of the invention, which is as follows:

Referring to the drawings, F represents a suitable machine-frame of any approved design, the same supportingin suitable bearings the drive-shaft S, having at one end a beltpulley P, driven from any suitable source of power. (Not shown.) Mounted on said shaft is a pinion 1, which meshes with a gear-wheel 2 on a parallel shaft S. The latter is provided with a smaller gear-wheel 3, meshing with a gear-disk 4, mounted on shaft S on the upper section F of the machine-frame. The arrows in Fig. 4: represent the relative direction of rotation of the several parts, as described. Carried also by the main shaft S is a belt-pulley 5, from which passes a belt 6 over the terminal pulley 7 of a spiral con- Veyer or screw 8, mounted on the base of the trough 9, carried by the standards 10 10 on top of the machine-frame. A suitable tightening pulley or idler 11 is provided for the belt 6, as usual in this class of machines. The composition or material from which the fire-kindlers or fuel-blocks are to be formed is fed into the trough 9 from any convegient source, (not shown,) the screw conveyer carrying the material forward until the same comes opposite the opening 12, formed in the trough, where it drops, partially to the bottom of the feed-head receptacle l3 and partially on top of thecut-oif piston 14, Figs. 5, 10, where the feed-head 15 shoves it into the space formed between the inner male member or tongue 16 of the die and the outer enveloping female member or plunger 17, the compression of the material being finally eflected by c the approach of the plunger 17 and cooperating plunger 18around the tongue 16,. the result being a' hollow fuel-block B, Fig. 21.

The manner of molding and compressing the block B, the manner of expressing from it any excess of water, moisture, or liquid bydrocarbons which enter into its composition, and the manner of ejecting the block when completed are all accomplished by a series of cams, which are themselves actuated by the driving power of the machine, and while systoms of cams are in themselves not new in machines of this class, my present arrangement contemplates a compactness and simplicity of structure and positiveness of action not attained in the majority of machines of this type.

The gear-disk 4 has formed thereon a camtrack a, having concentric portions 0/ a, traversed by the pin (or roller) 19 at one end of a bent lever 20, pivoted to a bracket 21,'the opposite end of the lever being pivotally connected to the lower end of a link 22, whose upper end is hinged to the free end of an arm 23, carried at one end of a rock-shaft 24, mounted on top of the bracket 25. The opposite end of the rock-shaft 24 carries an arm 26, which in turn is pivotally coupled to the lower end of a link 27, whose opposite end is hinged to one member of a bell-crank lever 28, mounted on top of the standards 10 10, the opposite member of the bell-crank being pivotally coupled to a link 29, which is in turn connected to the plunger 18, previously referred to. It is obvious from the foregoing that with the rotation of the gear-disk 4 in the direction as indicated the cam-track will cause the plunger 18 to reciprocate up and down and assume first one and then the other of its extreme positions, Figs. 5, 8, it being temporarily at rest while the pin 19 is traversing the concentric portions a a. with the plunger 18 is the plunger 17 and tongue 16, since by their combined action the block B results. The base of the plunger 17 is coupled to a link 30, which connects it to one end of a weighted lever 31, mounted on a fulcrum-rod 32, the former being provided on opposite faces with pins 33, traversing the cam-tracks b and their concentric portions 1) "on the cam-disks 34, mounted on the shaft S. Rotating as the disks 34 do in the direction of the arrow, Fig. 5, they gradully constrain the pins 33 to move toward the center of the disks, and thus force the, plunger '17 upward to the position indicated in Fig. 5. By the time the pins 33 have reached the points a; of

their respective earns the plunger will have imparted thereto a final movement upward, (at which instant the plunger 18 has begun its receding or upward movement,) this final movement raising the block B to a plane on a level with the ledge L, by which the block is received, Fig. 21.

The tongue 16, by which the opening in the fuel-block B is formed, is operated as follows:

I The base of the tongue carries a collar 35,

Cooperating connected thereto by pins 36 36, which pass through longitudinal slots 37 37, formed in the opposite walls of the plunger 17, to allow for the necessary reciprocation between the parts. The remaining two sides of the collar are provided with arms or elongated pins 38 38, which project through the sinuous longitudinal slots 39 39 of the standards 10 10, the outer projecting end of one arm 38 being pivotally connected through a link 38' to one end of a balance-lever 40, mounted on the rod 32, the outer projecting end of the other arm being connected through a link 38" to one end of a lever 40, mounted on the same rod 32, the opposite end of said lever 40' being provided with a pin 41, traversing the cam-track c and its concentric portion 0' of the disk 42, mounted on the shaft S, Figs. 4and 6. During the passage of the pin (or roller) 41 along the concentric portion dot the trackccthere is sufficient play allowed for the lever 40 to permit the plunger 17 to carry the tongue 16 with it while the former makes its final movement in raising theblock B to thellevel of the ledge L, as previously described. In this final movement a tappet or peg 42 on the collar 35 strikes the lower end of the stem 43 of a valve 44, normally plugging the end of the cut-off piston 14, Fig. 10, allowing the water and other fluids expressed from the block to drain and be discharged from the machine,

the valve being subsequently. seated by the coiled spring 45, confined between the guidelugs 46 46, one end of the spring being connected to said stem. The opening of the valve 44 of course takes place after the formation of the block and its elevation to the plane indicated in Fig. 21 and after the cut-off piston has been elevated to a position to form a retaining-wall for the block during its compression, Figs. 5, 14, and of course after the feed-head has been retracted to a position to begin the next feed operation, Fig. 5. During the feed operation the cut-ofi piston occupies its lowest position, Fig.- 8, it being reciprocated between these two limits by the following mechanism: The cut-off piston is hollow, having confined therein a pivoted link 47, whose lower end is pivotally coupled to a balance-lever 48, having an arm 49 rigidly secured thereto, the free end of thelatter having a terminal pin 50 traversing the cam-track d, and its concentric portion cl of the cam-disk 51 mounted on shaft SC/ When the parts thus far described occupy the position shown'in Figs. 8, 10, the feed-head 15 feeds the material into the die, as indicated in Figs. 7 and 8, the composition first striking-the pyramidal apex 16 of the tongue, being subsequently well shaken down into the space around they tongue by thevibratory motion imparted to the latter during its reciprocations along the sinuous slots 39, previously referred to. The recipro cation of the feed-head is accomplished as follows: The latter has pivotally secured thereto a stem 51, whose opposite end is coupled to one arm of a lever 52, pivoted to a stud or boss 53 on a bracket 54, the opposite arm of the lever having a pin 55 traversing the camtrack e e on one face of the cam-disk 56, mounted on the shaft S". The opposite face of the disk 56 is provided with a cam-track ff, traversed by a pin 57 at the end of one arm of a lever 58, rocking about a stud 59 on a bracket 60, the free end of the opposite arm being pivotally coupled to the adjacent end of a link 61, passing through lugs 62, the opposite end of the link 61 being connected to an arm 63, projecting laterally from the crossbar of the adjacent end of the ejecting-frame 64, the latter being in the nature of an oblong frame, Fig. 9, one end of which in its retraction or outward movement comes in contact with the block B when fully elevated, drawing the latter after it and depositing it on the ledge L, Fig. 21. The lateral bars of the frame 64 are guided in suitable grooves or ways 65, formed in the standards 10 10.

It will be observed that the series of camtracks by which the movementsto the several parts are imparted are composite in their nature, having portions both eccentric to and concentric with the axes of rotation of the disks on which the cam-tracks are disposed. During the passage of any lever over the concentric portion f any cam-track no motion results to the parts connected to such lever,

and the several cams are so set relatively toone another and so proportioned that for any period of rest of those parts actuated by one cam the parts connected to other cams are being actuated, and vice versa. Thus, for example, while the cut-01f piston occupies the position shown in Fig. 10 during the brief interval that the arm 49 is traversing a concentric portion of its cam-track the feed-head is operating, and during the interval that the same cut-ofi is in the position shown in Figs. 13, 14 the cams are actuating the pistons 17 18 and tongue 16, and so on, as clearly obvious from the foregoing to those skilled in the art.

WhileI do not wish to be limited to the particular curvatures of cam-tracks here shown, I have found that the forms illustrated give very superior results both in the matter of rapid compression of the blocks and reduction of the friction incident to machines of this type. It is further apparent that I may depart in minor details of construction without in any wise afiecting the nature or spirit of my invention.
