CHARLES 1V. RAYMOND, OF DAYTON, OHIO.
BRlCK-PRESSING MACHINE.
SPECIFICATION forming part of Letters Patent No. 476,928, dated June 14, 1892.
Application filed October 1, 1891. Serial No. 407,409. (No model.)
To all whom it may concern.-
Be it known that 1, CHARLES W. RAY- MOND, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Brick-Pressing Ma chines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.
My invention is designed as an improvement upon the presses described and claimed 1n myprior patcn ts, No. 354,226, dated December 14, 1886, and No. 417,837, dated December 24, 1889; audit has for its object the improved construction and mode of operation of presses of this character, whereby their capacity is increased.
The novelty of my invention willbe herein set forth, and specifically pointed out in the claims.
In the accompanying drawings, Figure 1, Sheet 1, is a side elevation of a press embodying my invention. Fig. 2, Sheet 2, is a central sectional end elevation of the same. Fig. 2, Sheet 3, is a sectional plan view through the dotted line a: m of Fig. 1. Fig. 3, Sheet 4, is an enlarged sectional detail in elevation through the compress-box and its carrier, showing the automatic mechanism for partially dropping the movable bottom of the box. Fig. 4, Sheet 4, is a detail of the bottom of the rod and its lifting and releasing plate, looking from the left of Fig. 3. Fig. 5, Sheet 4, is a side elevation of one of the carrier-actuating gears and cams. Fig. 6, Sheet 2, is a sectional elevation of a modification in the brick-feeding mechanism. Fig. 7, Sheet 2, is a plan View of Fig. 6.
The same letters of reference. are used to indicate identical parts in all the figures.
As in my prior patents, the main frame is composed of the arch A and base 13, Fig. 1, in one strong integral casting. Pivoted, as at a, on the upper side of the base are two levers O, to the upper ends of which are pivoted two similar levers D, said levers being connected at their central pivots by a link E, to one end of which is pivoted the inner end of a horizontal pitman F. The upper ends of the levers D are pivoted, as at b, to the under side of thehorizontal carrier G, provided at its ends with guideways engaging planed ribs 0 upon the inner sides of the arch A, as shown. Upon the carrier is removably secured the mold or compress box 11, open atits top, of the usual or any suitable construction, and in which the bricks are pressed against the usual or any suitable stationary platen I, carried by and vertically adjustable on the arch A.
IVhile in operation the carrier and compress-box are given a constant vertically-reciprocating motion through the medium of the toggle-levers O D, link E, and pitman F by the following means, referring to Figs. 1,
2, and 5: In a supplemental frame .1, secured to the arch A at one side, are journaled two horizontal shafts K L, the former having fast thereon the driving-pulley M and two small pinions N, meshing with two larger gears 0, fast upon the shaft L. Upon the inner side of each of the gears O is formedacam-groove cl, Fig. 5, the one being the counterpart of and coincident with the other. In these camgrooves are confined friction-rollers journaled upon a transverse pin or studs project ing from the outer end of the pitman F, or, as shown in the present instance, from a headpiece f upon the outer end of the pitman. To support the outer end of the pitman and to maintain it in a substantially horizontal position at all times, I employ a link P, Fig. 1, pivoted at its lower end, as at 9, upon the base B and pivoted at its upperend to a pendent arm of the head-piece f. As the gears O are rotated by the pinions N the cam-grooves d cause the reciprocation of the pitman F and the raising and lowering of the carrier G and box 11, as will be readily understood.
To prevent jar on the downstroke of the carrier G, I provide the rods Q, Fig. 1, which are secured to the carrier at their lower ends and extend up into tubes R upon the arch A. Springs h surround the rods Q within the tubes and are put under tension and act as butters upon the downstroke by means of collars or nuts 71 upon the upper ends of the rods engaging the springs, as shown by the broken away portion of one of the tubes in Fig. 1.
Journaled in brackets S, Fig. 2, secured to the arch A, is a horizontal shaft T in the same plane with but at right angles to the shaft L, by which it is driven by means of the intermeshing bevel-gears j. as in my prior patent of 1889. Driven by this shaft T through the medium of the drive-chain 7a is an endless apron U, whose inner end is carried upon and vibrates with the carrier G, just as shown in my last-mentioned patent or in any other suitable manner for carrying off the bricks after they have been pressed in the box H.
Rigidly secured to the arch A, opposite the apron U, is a horizontal fceding-tableV, Figs. 1, 2, and 2. This table is supported at its outer edge by legs W, extending to the base B, and it is so located as to have its upper surface exactly flush with the top edge of the com press-box H when the latter is at its lowermost limit of stroke, as seen in Fig. 2, the compress-box having a flange on that side at its upper edge, as shown at Z.
by imposing the weight of the feeding-table and its associated parts upon the drivingpower ofthe machine. The present construction avoids this objection, as the feeding-table is stationary and carried by the frame of the machine.
The feeding-pusher is a plate 172, Figs. 2 and 2, set vertically upon the table V and supported upon the inner end of a rod n, whose outer end passes through a guide-box 0 upon the rear edge of the table. Pivoted between pendent hangersp upon the under side of the table V is a lever q, whose upper end is connect-ed by a pivoted link 7" to a pendent lug upon a collar 3, ad justably clamped upon the rod a. The lug extends down through the slot t in the table V. Fast upon the shaft T is a wheel or disk A, Figs. 2 and 2, having formed upon one side a camgroove 10, in which is confined a friction-roller 4) upon a lever B, pivoted, as at 10, upon the base B. A link or pitman O pivotally connects the upper end of the lever B and the lower end of the lever q, so that the rotation of the disk A causes the reciprocation of the rod 11 and pusher m upon the table V, as will be readily understood.
Transversely of the arch A and beneath the same and the carrier G is a supplemental arch D, secured to the base B, Figs. 1, 2, and 3. Guided through a perforated lug a in the top of the arch D is the rod or leg E, extending up through an opening in the carrier G and carrying the movable bottom F, suitably constructed and snugly fitting within the compress-box II, as in my prior patents. During the upward stroke of the carrier and compress-box the bottom F forms the bottom of the compress-box and is carried up during the act of pressing the brick; but during the downstrokc of the compress-box the leg E is arrested, as presently explained, and the bottom E expels the pressed brick from the compressbox, as in my former patents.
Supported and guided in boxes I), Fig. 3, upon and near the top of the arch D, is a horizontal rod 0, having secured upon its end In my last-mentioned patent the feeding-table was secured to and vibrated by the carrier, therenext to the lever q a pendent toe-piece d, with which at the proper time a pendent lug 6 upon the pitman 0 engages to slide the rod 0 in one direction and to put a coiled spring f upon its opposite end under tension. The spring f surrounds the rod and is confined between the box I) and a nut upon the adjacent end of the rod. Fast upon the rod 0', between the boxes I), is a plate g, Fig. 4,rest iug upon a cross-piece 7L of the arch D, and having its edge adjacent to the legs E beveled, the lower end of the leg being also beveled. The cam-groove u is so laid out and the parts for operating the pusher are so adj usted that as the carrier and compress-box descend to the position shown in Fig. 2 the plate g is directly under the leg E, while the pusher m begins its inward or feeding stroke. The bottom F has ejected the already-pressed brick, and is, with the top of the compressbox, flush with the top of the table V. At this point the rollers e of the pitman F are in the dwell of the cam-groove (Z, and remain so until the pusher at has brought the unpressed brick into contact with the pressed brick and has forced the latter far enough onto the apron U or any other transporting mechanism for the latter to complete its removal. Just as or slightly before the unpressed brick entirely registers with the mouth of the compress-box the pitman 0 draws the plate g from 11I1( er the leg E and permits it and the bottom to drop to the position shown in Fig. 3, thereby forming a slight cavity in the top of the compress-box, into which the unpressed brick falls and is arrested. The purpose of the partial dropping of the bottom F is to prevent the overshooting of the unpressed brick under the momentum of the pusher and to insure its properly registering with the mouth of the compress-box. As the pusher m recedes the lug c releases the toe d and the spring f draws back the rod 0, so that the plate 9 passes under the leg E, as in Fig. 2. Just as the leg E is dropped, as above described, the rollers c leave the dwell of the cam-grooves d, and the carrier G and the box H begin to ascend to press the brick just deposited.
H, Figs. 1 and 2, is simply a guide-gage for the unpressed brick, made adjustable upon the table V.
The modification represented in Figs. 6 and 7 consists in providing a rectangular upright support I, secured upon the table V and servin g to hold a column of unpressed bricks. The pusher in this instance is a slide J, passing under the support I and as wide as and as thick as the brick. Its upper side is ribbed so that there is but slight frictional contact between it and the brick resting upon it. At the extreme backward throw it passes from under the column of bricks, which then drops upon the table. Upon the forward movement of the slide it engages with the lowermost brick and carries it forward from under the others, which again rest upon the slide,
and deposits it in the mouth of the compressbox, as before described.
YVhile I have shown the parts so adjusted as to only partially drop the bottom F just as the unpressed brick registers with the mouth of the compress-box, it will of course be understood that myinvention in this particular is not to be limited to the degree of dropping the bottom, as the parts may be so adjusted as to drop the bottom entirely until it rests upon the fixed support.
Having thus fully described my invention, I claim- 1. In a brick-pressing machine, the combination, with the carrier having vertical reciprocating motion and a compress box carried thereon and provided with a movable bottom for expelling a pressed brick, of a stationary feeding-table arranged to j be flush with the top of the compress-box at its lowest limit of stroke and a feeding-pusher upon said table and actuated automatically by the press, substantially as described.
2. In a brick-pressing machine, the combination, with the carrier having vertical reciprocating motion and a compress-box carried thereon and provided with a movable bottom having a pendent leg, of an automatic feedingpusher, a releasing-block for the leg, and connecting mechanism so adjusted that when the feeding-pusher carries an unpressed brick over the mouth of the compress-box'the block is withdrawn and the leg and bottom permitted to drop, substantially as described.
3. In a brick-pressing machine, the combination, with the leg E and pusher-pitman 0, having the lug c, of the rod 0', carrying the toe d and plate 9', and the retracting-spring f substantially as and for the purpose specified.
4:. In a brick-pressing machine, the combination, with the carrier G, of the rods Q,arch A, tubes R, and springs h, substantially in the manner and for the purpose specified.
