Specification of Letters Patent.
Patented Aug. 21, 1906.
Application filed February 15, 1904. Renewed July 2. 1906. Serial No. 324,492.
To aZZ whom it may concern:
Be it known that 1, WILLIAM E. J AQUES, a citizen of the United States of America, re- Siding at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Apparatus for Making Cementitious Products or Artificial Stone; and I hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.
This invention relates to improvements in apparatus suitable for use in manufacturing cementitious products or artificial stone.
One object of this invention is to make a cementitious product or artificial stone whose constituent particles are closely compacted and which is uniform in strength and durability.
Another object is to form a vertically-arranged column of moist and unset cementitions material, to elevate the said column intermittently by successive additions of cementitious material to the lower end of the column, to remove sections successively from the upper end of the said column, and to facilitate the separation of the said sections from the upper end of the column.
Anoth r object is not only to compact cementitious material added to the lower end of the column from below, but to utilize also and largely the weight of the cementitious column in compacting the material thus added to the said column.
Another object is to prevent any waste of moisture or cementitious slurry gravitating from the lower end of the cementitious column and to utilize such moisture or cementitious slurry in connection with fresh moist and unset cementitious material fed to the lower end of the said column.
With these objects in view, and to the end of realizing other advantages hereinafter apearing, this invention consists in certain eatures of construction and combinations of parts hereinafter described, and pointed out in the claims.
My improved apparatus is illustrated in the accompanyin drawings, wherein Figure 1 is a si e elevation, largely in section, of the said apparatus. Fig. 2 is a top plan of the lower portion of the apparatus, partly in section, on line 2 2, Fig. 1. Fig. 3 is a side elevation, largely in section, of the lower portion of the apparatus. In this figure the plunger G is shown in its upper position and the plunger F appears inits inner position. Fig. 4 is a top plan of the upper portion of the apparatus. Fig. 5 is a vertica section on line 5 5 Fig. 1.
Referring to the said drawi'n s, "A designates a vertically-arranged hol ow column, shaft, or tube wherein a moist and unset cemcntitious column is formed. The art A will hereinafter in this specification e referred to as a shaft, in whose interior passage-wayB ccmentitious material is accumulated to form a cementitious column C. The passage-way B extends from within the lower end to the upper end of the shaft A. The cemcntitious column 0, composed of moist and unset ccmentitious material, is elevated and elongated within the shaft A by the addition. to the lower end of the column of moist and unset cemcntitious material. The drawings illustrate the formation of and manner of elongating the column 0, and sections or pieces are successively removed from the upper end of the said column, as will hereinafter appear.
At one side of and adjacent to the lower end ortion of the shaft A is a hop er D, whicii is supplied with the moist an unset cementitious material C, which is to be fed and added to the lower end of the cementitious column C, formed within and by the said shaft.
A desirable ccmcntitious mass used in making cemcntitious products or artificial stone is a concrete or mixture having any suitable cementitious substance-such, for instance, as hydraulic ccmentas an ingredient and comprising also sand and moisture in suitable roportions. The cement or cementitious substance and water are first mixed together so as to form a cementitious slurry. Then this slurry is added to the sand in suitable proportionsas, for instance, in the proportions of one part, by weight, of the slurry to two parts of sand. Then the cemcntitious slurry and the sand are thoroughly mixed to ether.
The hopper D is provided at its lower end with a downwardly-discharging opening or outlet (1, which connects with the interior chamber 6 of a horizontally-arran ed case E and a plunger F snugly fits witin and is capable of reciprocation endwise of the chamber c and feed. cementitious material receivcd by and within the said chamber from the hopper D into the interior passageway B .ger F; that the of the shaft A through a lateral charging aperture or inlet a, with which the said shaft is provided at the discharging end of the said chamber. The shaft A extends far enough below the case E to accommodate the location and operation of a plunger G, which fits snugly within the lower end of the said shaft and is capable of reciprocation vertically.
The charging aperture or inlet a of the shaft A extends upwardly from the bottom of the chamber a, and preferably the full width of the said chamber, as shown in Fig. 2. The aperture (1 establishes communication, therefore, between the passage-way B and the chamber e, and preferably extends upwardly far enough above the chamber e, as at 10, (see Figs. 1 and 3,) to establish communication also between the outlet cl of the ho er D and the said passageway.
The plunger F is operated 1n any ap roved manner, and preferably has outward y-projectin arlnsf, which (see Figs. 1 and 2) are proviced with rollers h, arranged horizontally and in line endwise and at a right angle to the path of the said plunger, which rollers engage with cam-forming grooves is, formed in a cam-wheel K, which is operatively mounted on a suitablysuppo' ted shaft L, arranged horizontally and at a right angle to the path of the said plunger.
The plunger G is operated in any approved manner, and preferably has 9. depending stem 9, which is proi ided at its lower and free end with a roller l, arranged horizontally and at a right angle to the path of the said plunger G. The roller l engages the cam-forming peripheral surface of a camwheel M, which is operatively mounted on a suitably-supported horizontal shaft N, arranged parallel with the shaft I) and operatively provided with a driving-wheel n. The plunger G obviously lowers by gravity and is elevated by the cam-wheel M.
An operative connection between the two shafts L and N is established and comprises, preferably, an endless chain 0, leading over and operatively engaging sprocket-wheels I and J, which are operatively mounted on the shafts L and N, respectively.
The arrangement of the parts and the trend of the cam-forming surfaces of the cam-wheels K and M are such that the plun ger G in its lower position, as shown in Fig.1, has its upper and pressure-exerting face flush with the bottom of thechamber e; that during the first position of the dwell of the said plunger in its lower position the plun er Fis 111 its outer position; that moist an unset cementitious material is fed from the hopper D into the chamber e in advance of the plunlunger F is actuated forwardly or inwar 1y to feed the material fed in advance of the said plunger through the aperture or inlet a, into the passage-Way B and onto the plunger G; that the plunger G remains in its lower position during the inwardftravelor feeding operation of the lunger F and adds the said material to the ower end of the cemeintitious column during the next-succeeding upward. movement of the plunger G; that the plunger F does not move as far as the aperture a during its feeding operations, so as to avoid interruption in the communication between the chamber e and the inlet of the hopper l) and so that any excess of material in advance of the plunger G can escape or return during the feeding operation .of the said plunger G back into the said chamber or into the hopper; that the two plungcrs F and G make their return or idle strokes preparatory to the next-succeeding feeding operation of the plunger F, and that the plunger G in its upper position, as shown in Fig. 3, does not cover the upper end of the aperture or inlet a where the said inlet communicates directly with the outlet of the hopper, so that con'lmunication between the passage-way B and the interior chamber of the hopper is never interrupted and cementitious slurry or moisture gravitating from the (GIlIGDlJltlOUS column 0 or displaced from the said passage-way during the feeding operations of the plunger G can escape into the hopper and into the chamber 0, and the cemcntitious slurry or moisture 9 thus displaced or escaping from the shaft A is not only not wasted, but actually used to great advantage in insuring the presence of the required amount of cementitious substance and moisture in the charges of material successively added to the lower end of the cementitious column.
The shaft A tapers slightly downwardly from the horizontal plane at which sections are successively removed from the cementitious column formed in the said shaft to the path of the plunger Gthat is, the passage-way B is gradually enlarged upwardly from the path of the plunger G to the hon zontal plane where sections are removed from the upper end of the cementitious column (I, so as not only to facilitate the elevation of the said column by the said plunger during the addition of fresh cementitious material to the lower end of the said column, but to seat the said column. as theparticles thereof become closely compacted upon 0 7 positely-arranged slightly upwardly (liverging walls of the said passa e-way, and thereby adequately support t e column within and from the shaft A and ositively prevent any descent of the sai( column within the said shaft.
Very desirable results have been obtained with shafts from four to six feet highabove the path of the plunger G, and the material composing the upper end of the cementitious column is in a very satisfactory condition for the severing of sections from the said end of the said column.
IIO
It will be observed that by the formation and upward feeding of a cementitious column within the shaft A the particles composing the said column are closely compacted, and the compacting of the particles of any cementitious material added to the lower end of the column is brought about not only by the plunger G in adding fresh cementitious material under pressure to the lower end of the column, but also and largely by the weight of the column.
The lower portion of the shaft A from the upper extremity of the path of the plunger G downwardly is preferably uniform in crosssection and forms a guide for the said pluner. g The cementitious column during the addition of fresh moist and unset cementitious material to the lower end of the column is lifted into an interior chamber or compartment of a reciprocating frame Q, which is movab e laterally in a horizontal plane at the upper end of the shaft A. The frame Q is provided with two corresponding chambers or compartments Q, which are arranged. a suitable distance apart longitudinally of the path of the said frame. Each chamber Q preferably has the dimensions required to iold a cementitious block or section capable of being subdivided into a predetermined number of bricks on edge, and the passageway B next below the path of the frame Q corresponds in dimensions horizontally with the dimensions transversely of the said chamher. The shaft A, next below the path of the frame Q, is provided (see Fi s. 1 and 5) with an upwardly-facing surface t, which extends around the passage-way B and forms a bottom bearing or seat for the frame Q, which is uided during its reciprocation by two guideorming walls 12, with which the shaft A is provided at opposite sides, respectively, of the path of the said frame. The chambers Q extend vertically through the frame Q, and the arran ement of the parts is such that one or the ot er of the chambers Q of the said frame is exactly in line vertically and in full registry with the passage-way B, according as the said frame is in the one or the other of its positions.
Two pallets P and p are arranged a suitable distance apart longitudinally of the path of the frame Q at opposite sides, respectively, of and in close proximity to the shaft A. Each pallet rests removably u on a vertically-movable table R, which is arge enough in dimensions horizontally to render it ca able of adequately supporting the said pal ct, and the shaft A is provided with verticallyarranged guides 13 for the said table. Each table R is provided at its under side with a roller 7", which engages the camforming peripheral surface of a cam-wheel t, operatively mounted on a horizontally-arranged shaft T, which is suitably supported from the shaft A. Each shaft T is arranged, therefore, a suitable distance below and at a right angle to the path of the frame Q. T he shafts T of the mechanism instrumental in the operation of both tables R are operatively connected with each other by an endless chain a, leading over sproelmt-whcels TV and w, mounted on the different shafts T, respectively.
In Fig. 1 the frame is shown in position with one of its chambers Q in full registry with the assage-way B and empty, ready to receive the upper end of the cementitious column (1 during the elevation of the said column during the next succeeding upward stroke of the plunger G, and the other chamber Q of the said frame is shown occupied in the said. figure by a cementitious block of section severed and removed from the said column and in position to descend from the en aging chamber of the said frame with the a let P, and in the said figure the other pallbt p is shown laden and in its lower position next preparatory to the replacing of the lastmentioned laden pallet by an unladcn pallet.
The frame Q is provided at one end (see Figs. 1 and -1) with two outwaidly-projecting arms 15, which extend longitudinally of the path of the said frame at opposite sides, respcctively, of the said path and are provided with two parallel rollers 16, which extend transversely of the said frame and are arranged a suitable distance apart longitudinally of the frame. A camwheel 17, which has a cam-forming peripheral surface arranged fo operate between the rollers 16, is operatively mounted on a shaft 18, which is arranged horizontally and transversely of and below the path of the frame Q and supported in any approved manner from the shaft A. The shaft 18 is operatively provided with a driving-wheel 20, to which power is applied in any approved manner. An end-' less chain 24 leads over a sprocket-wheel 2.3, operatively mounted on one of the shafts T, and also operatively engages a sprocket-wheel 25, o erativelymounted on the shaft 18. It will )G0l')S[\IVG(l also that the arms 15 of the frame Q (see Figs. 1 and 4) are slotted, as at 19, to accommodate the location of the shaft 18.
The parts are so arranged and timed that each chamber Q of the frame Q during the reciprocation of the said frame comes into full registry with the passage-way B when the other chamber Q of the said frame is in position over a pallet; that one of the chambers Q is brought into osition over the pallet P, or the other chain )er Q is brou ht into pdsition over the pallet p, accorr ing as the frame Q is in the one or the other of its positions; that the 11 per portion of the cementitious column. (T when lifted into either chamber Q of the frame Q, so as to fill the said chamber, is severed horizontally from the remainder of the column during the next stroke of the said frame; that the different chambers Q are filled alternately; that sec tions are removed successively from the upper end of the said column, but in opposite directions alternately; that the frame Q dclivers or feeds cementitious sections alternately onto the pallet of the different tables, respectively, and that each pallet-bearing table when the pallet thereon. is to receive the next cementitious section moves into its upper position ready to receive the said cementitious section, which may, if desired, be subdivided into bricks or predetermined products.
Each chamber of the frame Q is quadrangular in plan and is shown large enough in dimensions horizontally and deep enough vertically to hold a cementitious block or section C, divisible into ten ordinary bricks. The said chamber is therefore four inches deep vertically, about twenty inches long, and eight inches wide and arranged wlth its length widthwise of the path of the frame and of course the passage-way B of the sha t A next below the said path measures, therefore, about twenty inches transversely of the said path and eight inches longitudinally of the said path. Each chamber Q when in position, registering fully and exactly with the passage-way B, as shown in Fig. forms an upward extension of the said. passage-way and permits the cementitious column C, formed in and by the shaft A, to be lifted into, and thereby fill, the said chamber. The parts are so arranged and timed, furthermore, that fresh, moist, and unset cementitious material is added to the lower end of the column C by the plunger G, and the said column. is lifted by and durin the addition of the said material to the co umn into a chamber Q, when the said chamber is brought into full registry with the passage-way B and against the under side of a head 14, with which the shaft A is provided, which head extends transversely of and over or bridges the path of the frame Q and extends between and is rigid with the walls or guides 12. The head 14 (see Figs. 4 and 5) is large enough in dimensions horizontally to render it capable of completely covering a chamber Q when the said chamber is brou ht into full registry with the passage-wayand forms an abutment for the upper end of the elevated cementitious column and operates to trowel the top of the cementitious sections severed and removed successively by the frame Q from the said column during the reciprocation of the said frame.
The pallets P and p are large enough in dimensions to respectively receive a cementitious section C, severed from the column C and to completely cover the said section from below. A pallet suitable for receiving a cementitious section C twenty inches long and eight inches wide would therefore be at least twenty inches long and eight inches Wide and arranged transversely of and next below the path of the frame Each cementitious section (V conveyed by the frame Q onto a pallet will upon being received by the said p allot descend by gravity with the pallet during the next descent of the table bearing the said pallet; but, if desired or required, pressure by a plunger (not shown) or otherwise 1 may be exerted on top of the said cementitious section to assist gravity in loosening the said section. relative to the frame As shown in Fig. 1, the upper portion of the shaft A is preferably provided with ins as, which engage grooves y, formed in an arranged vertically of the exterior of the tables R, and the arrangement of the parts is such that the grooves y are engaged by the pins :r in any position of the said tables, and the mutually-engaging pins :0 and grooves y are obvious y instrumental in guiding the tables during the vertical reciprocation of the said tables.
1 would here remark that the cementitious slurry employed with sand in the proportion hereinbefore specified in making the desired cementitious mass contains more liquid or moisture and cement or cementitious substance than neccssary for incasing all of the particles of the sand of the original mass; that the solid particles of the cementitious column C are, more closely compacted as the said column ascends within the shaft A that obviously any quantity of cementitious slurry remaining free in the mass and not already employed in permanently incasin particlcs of sand with cement will during t e ascent of the column be spread or distributed and coat any surfaces newly formed upon particles of sand during the compacting of the solid particles of the mass within the shaft A, and any cementitious moisture not finding em loyment in coating surfaces of sand partic es will be squeezed downwardly and descend by gravity and escape at the lower end of the cementitious column, where the said moisture or thin cementitious slur is added to fresh moist and unset cementitious material next added to the lower end of the said column. I would remark also that the upper portion of the cementitious column is equally moist transversely; that the cementitious material added to the lower end of the column becomes drier as it ascends and be comes uniform in every respect transversely of the column that the sald material 11 on reaching the upper end of the column is w 'le still unset, but not too moist, in the most desirable condition for conversion into bricks or other desired cementitious roducts; that the said upper portion of the co umn is readily broken or. severed from the remainder of the column that the sections successively severed and removed from the up er end of the column are readily capable o subdivision while the material composing them has still to set and harden, and that the pallets laden with the cementitious blocks, bricks, or products are conveyed to and left in any convenient place until the bricks or products thereon ave completely set and hardened. It will be observed also that the mutually-engaging pins as and grooves y effectually prevent tipping of the tables R between the guides 13 and that the extension of the shaft 18 through the slots 19 in the arms 15 of the frame Q desirably steadies the said arms.
