Serial No. 425,677.
To all whom t may concern:
Be it known that I, WILLIAM It. CUNNING- HAM, a citizen of the United States, residing at Bueyrus, in the county of Crawford and State of Ohio, have invented certain new and useful Improvements in Olli-Bearing Attachments for Brick-Presses, of which the following is a specification.
This invention relates to the clay working industry and particularly to a mechanism for removing brick automatically from a dry press brick machine and depositing the same onto a conveyer.
The mechanism herein shown is in the nature of an attachment to a brick machine or press and it is capable of being applied or used in conjunction with any of the well known machines for messing brick with little or no modification of the construction shown.
The essential object of the invention is to enable the pressed brick to be handled automatically and to overcome the necessity of handlingl the brick by hand, thereby saving the exilvense of men to do the work of removing the brick from the machine and depositing the same onto the conveyor.
rVith this and other objects in view the invention consists el the parts and the constructions and combinations ol' parts which I will hereinafter describe and claim.
In the accompanying drawings forming part of this speci'lication and in which similar roteren le characters indicate like parts throughout the several views, Figure l, is a side elevation, partially in section, of an oli'- bearing attachment to a dry-press showing in outline a four-mold dry-press brick machine, which is illustrative of one of the many designs that my attachment is to be applied to. Fig. l is a detail showing the cam and bellcrank lever mechanism for the elevating rods. Fig. 2, is an enlarged detail, in section and plan of one of the lifting-heads showing the adjustable spurs. Fig. 3 is an enlarged detail of the lower portion of the elevating rod, showing the attachment of the connecting red, l5. Fig. I is a side elevation of Fig. 3. F ig. 5 is a front end elevation of the ollbearing attachment. Fig. 6 is a plan view of Fig. I showing parts broken away. Fig. 6 is a plan view of a portion of the press table and conveyor and the rack-bar and segmental bell-crank. Fig. 7 is a plan view of Fig. 8. Fig. 8 is a side elevation of a portion of a conveyor' of modified form. Fig. 9 is a modilication of the elevating and turning mechanism, which I will hereinafter' describe.
In Fig. l I show an outline of a dry-press brick machine of 'the four-mold type, although this machine may 'cpresent any form of brick press having any desirable number of molds. In presses of this type there is usually present a receiving table, l, which is shown in section, Fig. l, and a mold box, 2, in which the brick are formed. After the brick are formed they are delivered onto the table by the usual and well known charger', not shown, which pushes the brick from over the mold, after which the charger' lills the mold with loose material to be pressed. The charger is not shown but its construction and operation are well known and its function is to deliver the brick into the position shown in full lirios in Fig. l.
Iy reference to Fig. (i, it will be seen that the table is constructed with slots or openings, 3, 4l, 5 and 'for a four-mold press, but it will be understood that the number olslots or openings may be increased or decreased in accordance with the number of molds used in the press. In said lf'ig. o, the molds appear in plan in 'lull lines and the arrangement is such that one mold is used in conjunction with one oll the slots or openings in the table, through which openings suitable elevating-heads are designed to pass under the brick and to elevate the sam-e into the dotted positions shown in Fig. l, as I will hereinafter fully disclose.
As before stated, through each olI the openings 3, i.l 5 and oil the table l, designed to operate vertically a lil'ti read which is shown in the enlarged detail, Fig. 2, said heads adapted to engage and elevato the brick which have been passed or pushed over the openings, 3, -al 5 and (3 by the charger ol' the brick press, cach of said heads being provided wilh a number oll adjustable spurs, In Fig. 2, I illustrate l'our ol these spurs l'or each head, although more or less may be used, ilI desired, the spurs being threaded into the lifting-head and having pointed ends. Each lifting-head is composed ol' a plate through which the spurs are screwed, said plate having a hub, S), and being bored and tapped at l0. achlil'ting-head iscounected with an elevating-rod, ll, which is herein shown in the form of a bar square in crosssection, the upper end of said bar being of reduced thickness and being threaded, as at IIO 12, to permit the elevating-head, to be screwed the proper distance onto the elevating-rod. In order to lock the head and its rod in any position the parts have been adjusted, l employ a nut 13. As shown in Figs. 3 and 4 the lower end of the elevating-rod, 11, is turned spherical at 14, to permit the square bar to turn in the connecting-1'od, 15, said connecting-rod having a socket or being designed to fit the spherical end 14, and being slotted from side to side as shown by dotted lines 16, in Fig. 14. To the lower end of the connecting-rod, 15, is a pin, 17, which passes through the bifurcat-ed end, 18, of one arm of a bell-crank lever, 19, said lever having a hub, 20, and a short arm, 21, the outer end of which carries a roller, 22, mounted on a pin, 23.
Referring to Fig. 5, the brick are shown in full lines lying at rest on the table over the openings 3, 4, 5 and 6 after said brick have been pushed out of the brick press by the charger thereof, and it will be observed in said F ig. 5 that l use one elevating-mechanism for each brick. In the present drawings l show my improvement as used in association with a four-mold press, although two, four or siX molds are often used and any number of molds may be used without departing from the spirit of my invention.
Each of the elevating-rods, 11, passes through a sleeve, 24, shown more particularly in Fig. 1, said sleeve being provided with a square hole through its entire length to admit the corresponding elevating-rod, the upper end of said sleeve being provided with a segmental-gear, 25, better shown in Fig. 6, and the lower end of the sleeve being provided with a collar, 26, to prevent the sleeve from rising, said sleeve being also held in position by a bearing, 27, which is a part of the frame, 28, which is supported by uprights, 29 and 30, these uprights being bolted or otherwise fixed to a suitable carriage by the bolts, 31 and 32, which pass through base flanges, 33 and 34, of the uprights and corresponding flanges, 35 and 36, of the carriage, 68, as shown in Fig. 5.
The frame, 28, which is supported by the uprights, 29 and 30, is provided with bearings, 37 and 38, as shown in Fig. 6, which bearings are designed to support the horizontal transversely operating rack-bar, 39, the teeth of said rack being designed to engage with the teeth of the segments, 25, of the sleeve, 24, through which the elevating-rod operates. The rack-bar is shown as having teeth on its opposite sides, the teeth of one side engaging the aforesaid segments and the teeth on the opposite side and herein designated as 4l, being designed to mesh in the teeth, 42, of the segmental bell-crank, 43, which is located near one end of the rack-bar. The bell-crank, 43, is provided with a vertically-disposed hub, 44, through which passes the vertical pin, 45, whose lower end is secured in the hub, 46, which forms a part of the upright, 29, before described. The outer end of the arm, 47, of the bellecrank, 43, is shown enlarged as at 48, and provided with an elongated hole, 49, through which passes a shifting bar, 50, which is horizontally-disposed and has its outer end passing through a boss, 51, which forms a part of a plate, 52, as shown in F ig. 1, said bar, 50, being held in position by a set-screw passing through the boss and engaging the bar. On the shiftingbar, 50, are suitable slip-collars, 54 and 55 which are held in a desired position by screws, 56 and 67, this arrangement affording means for adjusting the collars in. proper position to cause the bellcrank, 43, to turn in a horizontal plane about the vertical pin, 45, at the proper time, as l will hereinafter describe.
The base plate, 58, of the machine is secured to an appropriate foundation by bolts, 59, or othersuitable means. To the base plate are also bolted the guide-frames 60 and 61 whose upper ends are provided with female guides, 62 and 63, these guides being made in the usual manner of providing two parallel surfaces. l prefer in the present case, to make the upper portion of the guideframe, 60, in the form of a Yflat surface, which is arranged. at right angles to form the lower wall or guide of the side frame, the upper wall of the guide being bolted parallel with the lower wall by the bolts, 64 and 65.
Bolted to the carriage-frame, 68, by bolts, 69 and 70, passing through the flanges 71 and 72, and through holes in the carriage, 68, are the male guides which are designed to work in the guides, 62 and. 63, the two sets of guides furnishing means of guiding the carri age as it travels to and from the brick press, as l will hereinafter describe.
On the vertical members, 73 and 74, of the frame or carriage, 68, are bosses 75 and 76, which support a cam shaft, 77, said bosses being bored to fit said shaft and to permit the shaft to revolve in the same. Secured to the shaft, 77, are four cams, 78, 79, and 81, which are secured to the shaft by set-screws, 82, but they may be otherwise secured if desired. lt will be noticed that four cams are herein shown, this being because the present illustration is of a four-mold brick press, and if a greater or lesser number of molds are used, the number of cams will be correspondingly varied. lt will be noticed, 1, that the cams are of different proportions, and that each of said cams operates its compan ion bell-crank by coming in contact with the roller, 23, on the outer end of the short arm, 21, of said bell-crank. The cams are ro vided with hubs which slip over the shaft, 77, and are secured by set-screws, 82, to said shaft. Projecting from the hubs of each of the aforesaid cams 78, 79, 80 and 81, are segmental-tracks 83, S4, S5 and 86, each of which has a different throw for a purpose l will hereinafter state.
Forming a part of the frame, 29, are suitable bosses, S7 and S3, which form supports for a stationary shaft, S9, said shaft passing through the hubs of the bell-cranks, 19, 19, 192, 193, thereby allowing said bell-cranks to oscillate on the stationary shaft. Also mounted on the shaft, S9, are suitable separating collars, 90, 91 and 92, which are for the purpose of holding the bell-cranks in proper position or in line with the brick-elevating heads, 9, before mentioned. By providing the cams of different throw and differential space and making` the bell-cranks independent of the shaft, 89, it is obvious that the ele-'- vating-heads can be lifted to different heights, as shown by dotted lines in F ig. 1 and the purposes of which l will presently state.
Mounted on the ends of the shaft, 77, and secured thereto by means of keys or other well known devices are cranks, 93 and 911, Fig. 5, the outer ends of which are forked or bifureated as shown at 95, 96, to receive the rollers, 101 and 102, which are mounted on pins, 97 and 98, which are in turn secured by cotter or other pins 99 and 100. The aforesaid. rollers, 101 and 102, are designed to engage suitable stationary cams, 103 and 1041, to cause the carriage, 0S, with the cam-shaft 77, and the bell-crank shaft, 39 and bellcranks, 19, to travel in thc direction of the arrow. W hen the carriage has reached the limit of its movement in the direction of the arrow, the continued revolution of the shalt, 77, will cause the rollers, 101. and 102, to come in contact with other cams, 106 and 107, which are stationary cams secured to the guide-frames, 60 and 61, by bolts, 110 and 111, whereby the carriage, (3S, with all of the parts mounted thereon is returned to its original position as shown in the side elevation, Fig. 1.
On the end of the shaft, 77, is mounted a bevel gear, 112, Figs. 5 and (i, adapted to mesh with a pinion, 113, said pinion being provided with an extended hub, 1.1-1, shown in section in Fig. G, having a shoulder, 115, and a collar, 116, said extended hub forming a bearing and being supported in a ournalbearing, 116, which forms a part of the carriage, 68. The aforesaid pinion, 113, with its extended hub `is bored to receive a shaft, 117, said shaft being provided with a spline which extends the length of the travel of the carriage plus the length of the pinion, and working in said spline is a feathered-key which is secured in the pinion, 113, whereby as the pinion is carried by the carriage along the shaft the key slides in the spline, which drives the pinion, 113, no matter what position the carriage may assume; the carriage is provided with an additional journal bearing, 11S, for supporting said shaft, 117.
Suitably bolted to the base-plate, 5S, are the pedestals, 119 and 120 the upper end of which forms ournal bearings 121 and 122 for the shaft, 117, said shaft being held from lateral movement by the collars, 123 and 121 which are secured to said shaft by suitable means, as set-screws, not shown. Secured to the shalt, 1.17, is a member of a universalcoupling, 120, a companion member, 127, of this coupling being attached to the angleshaft, 12S, on the opposite end of the angle shaft is a coupling member, 129, which is connected with a companion member, 130 attached to a shaft, 132, supported in journalbearings, 133 and 134, which form apart of a frame, 1.35, this frame being secured to a suitable foundation, 130, by bolts, 137, Fig. 5. The frame, 135, may, if convenient, be attached to or become a part of the main frame of the brick machine, but if not convenient, it can be arranged as herein described.
On the shaft, 132, is a bevel-gear, 13S, which meshes with and is driven by a pin,- ion, 139, mounted on a shaft 1-10, which in this particular case is the intermediate shaft of the brick machine. It may not always be convenient to arrange to drive the ol'- bearing attachment before described from this intermediate shaft of the brick machine as said marhines are not all designed alike. l simply show this part of the mechanism to be driven from machines to which the device is to be attached, but other arrangements for driving the olf bearing mechanism can be provided to suit conditions and without departing from the spirit of my invention.
Bolted to the fouiulation, 5S, by bolts, 1 A11-1 and 1-12, are two standards, 1113 and 1-1/1, whose upper portions are provided with flanges, 111-5 and 1416, through which pass bolts, 147 and 1li-S, which secure the plate, 52, to the uprighfs, which plate, 52, has bolted to it at proper intervals the roller-supports, 1419, 150 and 151, said supports being provided with flanges 152, through which the bolts pass to secure them to the plate, 52, said supports being also provided with hubs, 153 and 15-1, which are conuertial by overhead connections, 155, said hubs adapted as Y supports for the roller-slnifts, '1511. 'l`o the outer end of these last named shafts are mounted and secured the rollers, 157, and between the hubs or bearings, 153 and 15-1 and secured to the shafts, 150, are sprocketwheels, 15S, which are held in position by suitable means as by the set-screws, 159. 1t will be understood that each roller is provided with a shaft, sprocket and support, said sprockets being driven by a link-chain, 150, passing over the top of the same, and the lower portion of the chain being supported by rollers, 101, which revolve upon pins, 162, held in bosses 103, which form a part of the roller-supports, 1-19. rlhe chain, 1,00, is
of the link-type and is driven over a sprocket, 164, Fig. 5, which is mounted on a shaft, 165, which in turn is driven by a conveyer-belt, 166, in the usual manner. By reference to Figs. 5 and 6 it will be observed that the rollers, 157, are spaced farther apart than the rollers, 167 and 16S, which is due to the proper spacing of the rollers in relation to the brick molds and the elevating-heads, 7.
ln the detail lligs. 7 and 8 l show modification of the rollers and .vherein the intermediate rollers, 170, between the elevatingheads, 7, are made smaller and l place two side by side as shown at 169, said. rollers being provided with sprocket-wheels and being driven as previously described, and the rollers being arranged to roll by the friction of the brick as they pass over the same. rlhe advantage of the two rollers shown in Fig. 7 in place of one as shown in 6, is that if the brick has a tendency to wave as it passes over the rollers, 157, the two closely-arranged rollers, 169 and 17() will prevent this. lt will also be observed that in Fig. 8, the link chain has a slight elevation at the point marked 171, as it passes over the smaller rollers and this is for the purpose of holding tl e chain onto the small rollers. The sprockets, 180, being smaller than the sprockets, 158, and the rollers, 169 and 170, also being sma ler they should run faster so that the surface or periphery of the rollers should all travel about the same. The sin'ockets are so proportioned that they elevate the chain as shown.
Referring to Fig. 9, which is a modification showing a direct elevating and turning device, said F 9 shows the elevating bar, 11, and its hub, 7, as being immediately over the cam-shaft, 77, which is simply for the purpose of showing that the bell-cranks, 19, might be dispensed with without departing from the scope of the present invention. Such a construction as shown in F 9, would also be a very simple way to design the machine, but the objection to it is that the brick would have to receive a second plunger or in other words the charger would push out brick as shown by 13, F 9 and then the next plunger would push. the brick "13 to the opposite side of B by the brick E striking These brick being green easily crumble which dam the brick by one brick coming in contact with another to push the same out on the table, and thereby 1 deem it advisable to cons.' ruct the machine with the bell-cranks to operate the elevating-devices as shown in l? ig. 1 in preference to the construction shown in Fig. 9. It is equally apparent that the brick can be pushed forward off of the table in the direction that the charger delivers them onto the table. rlfhey could also be received upon a belt to convey them away, but the inconvenience ol' supporting and carrying a belt of sufiicient width to carry four brick abreast as shown in Fig. 5 makes it almost impracticable for the piirposes for which this attachment was designed. As the brick are to be conveyed long distances from the machine, and as this off-bearing attachment is intended. to be worked in connection with several machines located conveniently along one belt the impracticability of forcing the brick out onto a belt located in front of the machine will be apparent, and in order to get them onto narrow belt, it is necessary to reverse the brick from the direction that they are discharged from the molds by the charger.
in Fig. 1 the brick are supposed to be lying` upon the table with their long sides parallel with the axis of the rollers, 157, and the mechanism previously described is designed to elevate the first brick to the dotted position at C and the second brick at C the third brick at C;a and the fourth brick at @3. rllhis elevation of the brick one above the other permits the brick to be turned, with the heads 7, one being elevated above the other and clear of the same. After they are carried over the live rollers, they are made to assume the position of D D D2 D3 and when they are in this latter position they are ready to be lowered onto the live rollers, 157, to be carried by the same and delivered to the conveyor-belt, 166. ln order to allow the elevating-heads and their bars, 11, to pass between the rollers, 157, it is necessary to leave the ends of the rollers, 1.37, overhang leaving openings between the saine to permit the heads, 7, and their actuating rods, 11, to pass between the rollers.
The general operation of the apparatus before described may be stated as follows: The conveyer, 166, is driven from a power plant and has a fixed speed. This conveyer is adapted to carry the brick any distance out on the plant. The conveyer, 166, revolves the sprocket-wheel 164 and shaft, 165, which drives the chain, 160, and thereby imparts revolution to the rollers in the supports, 149, 150, and 151. As the shaft, 140, of the brick press revolves, it turns the pinion, 139 and this revolves the gear, 138, which in turn revolves the shaft, 132, and shaft, 128, which through the universal coupling` shown sets the shaft, 117, in motion. The revolution of the shaft, 117 gives motion to the pinion, 113 and gear, 112, which is mounted on the shaft, 77. This latter shaft carries the cams, 78, 79, SO and 81 and these coming in contact With the rollers, s3, of the bell-cranks, 19, the elevating-rods, 11, are raised carrying With them the heads, 7, until the latter come in contact with the brick lying on the table, elevating all of the brick at the same time, each cam taking care of its own elevating-rod, bellcrank, lifter-head and brick, the cam, 7S, only lifting the 'first brick sufficient to clear the table; the next cam, 70, elevates the second brick sufficiently high to clear the lirst one. The third brick is elevated by the third cam, S0, so that it clears the second one and the fourth cam, S1, clevatcs the fourth brick so that it clears the third, the several positions being shown in dotted lines in Fig. 1. Now as the shaft, 77, begins to revolve the arms, 93 and 0-1, carrying the rollers, 101 and 102 come in contact with the cams, 103 and 104, thereby causing the carriage to travel in the direction of the arrow A, in Fig. 1, thereby passing the brick from the position shown in the drawings over the center of the rollers, 157. As the carriage passes from the original position to carry the brick into the position over the rollers, 157, the enlarged portion, l1S, of the arm, 47 comes in contact with the collar, 54, and this causes the bell-crank to swing on the pin a5, thereby operating the segmentalportion 42, and causing the same to shift the rack-bar, 39, in a horizontal direction. This movement of the rack-bar through the segments 25 causes the sleeves 2st, to revolve and as these sleeves are provided with square holes in which the square lifting rods are mounted, the revolution of the sleeves is transmitted to the said lifting rods to thereby cause the lifting-heads, 7, to rotate. The spurs, S, of these heads being embedded in the brick canse the brick to be turned br {DJ (ID/?! ((Dg), ((Dl) and at the same time the arms 7S, 70, 80 and 81 being of different lifts and coming in contact with the roller of its companion bell-crank each bell-crank lifts its companion square lifting-rod, 11, elevating each brick above the other, and as the carriage passes over the roller it delivers the brick in the position shown at D, ly, D2, D3 at which time the cam 7 S, has revolved sufficient to permit the roller, 23, to pass o'fll of the cam and to assume its original position lowering the Vfirst brick onto the live rollers, 157, which carry them away. Shortly after the cam 79, allows its companion crank to drop brick D onto the live rollers to be carried which is followed by cam S0, and brick D2, which in turn is followed by brick D3, which is permitted to drop later by the cam, S1. As the last brick comes in contact with the rollers the elevating heads 7, are all lowered. to a line shown in the position in Fig. 1, and then the rollers 101 and 102 come in contact with the cams 106 and 107 and returnthe carriage to the position shown in said Fig. 1. As the carriage returns to its original position the enlarged end, 48, of the bell-crank, 47, comes in contact with the collar, 57 thereby causing it to rock on the pin, 45, to shift the rack bar 39, and revolve the heads 7 and bring them to their original position ready for the next operation.
