BRICK OR TILE CUTTER.

SPECIFICATION forming part of Letters Patent No. 488,343, dated December 20, 1892.

Application filed October 12,1891. Serial No. 408,504. (No model.)

To all whom it may concern.-

Be it known that I, A. ZELIFF WILLIAMS, a citizen of the United States, residing at Ohicago, in the county of Huron and State of Ohio, have invented a new and useful Brick- Cutting Machine, of which the following is a specification.

This invention relates to a machine for cutting brick; and the objects in view are to provide a cheap and simple machine of this class, adapted to be run with small expense and to be operated in part by the passage of the clay from the die of the brick-machine, whereby said machine may be said to be automatioin its operation, to adapt the machine for delivering the brick as cut, to be afterward manipulated for the purpose of drying; and to adapt the machine for cutting the brick cleanly and with accuracy.

Various other objects and advantages of the invention will appear in the following description, and the novel features thereof will be particularly pointed out in the claims.

Referring to the drawings:-Figure 1 is a side elevation of a brick machine constructed in accordance with my invention. Fig. 2 is a plan of the same. Fig. 3 is a longitudinal section. Fig. 4 is a transverse section, on the line 4: 4: of Fig. 1. Fig. 5 is a horizontalsection on the line 5 5 of Fig. 1. Fig. 6 is a transverse section on the line 6-6 of Fig. 3. Fig. 7 is a transverse section on the line 77 of Fig. Fig. 8 is a longitudinal section, on the line 88 of Fig.5. Fig. 9is a detail in transverse section on the line 9-9 of Fig. 2. Fig. 10 is a detail in longitudinal section on the line 101O of Fig. 5.

Like numerals of reference indicate like parts in all the figures of the drawings.

In this instance, upon the oblong base or support 1 there are bolted the four supportinglegs 2 of an oblong frame 3; which frame is provided upon its inner side and at its ends with pairs of opposite short tracks or ways 4, the ends of which are upwardly-disposed, forming stops.

Supported upon axles 5, Figs. 3 and 8 provided at their ends with flanged wheels 6, designed to ride upon the tracks 4, is an open framework or carriage 7, comprising in its make-up side, bottom, and top-walls. (See Figs. 3 and 8.)

A small framework or support 8, is supported upon the base 1, near one end of the machine; and upon the same bearing-boxes 9 are located, which boxes have mounted for rotation therein a short shaft 10, the outer end of which is operated by a rag-wheel 11, to which motion is conveyed from a brickmachine or engine for operating the same, through any suitable intermediate set of gearing.

From a cross-bar 13, Figs. 3, 5, and 6 connecting the opposite side-bars of the frame 3, rise standards 14 and 15, the same being located at opposite sides of the frame, and therefore at the longitudinal ends of the bar 13. That standard lat is provided with a vertical slot 16, while to the opposite standard there is pivoted as at 17, a transversely-disposed bar 18, the free end of which is designed to move in the vertical slot of the standard 14.. This bar is provided at its center with a bearing 19, Fig. 3 and in the same is journaled one end of a section 20 of the shaft 10, theouter end of the section 20 being connected to the section 10, by a gimbaljoint 21. Upon the shaft 20 Within the framefthere is mounted a basket-pinion 22, of considerable length.

Pairs of standards 24 Figs. 1 and 4 having a general L-shape, are secured to the opposite sides of the frame 7, near one end of the same, and each pair is connected by a transversely-disposed reciprocating-rod 25. These rods are mounted in bearings 26, formed in the upper ends of the standards 24, and in the present instance are cylindrical. incross section, though they maybe in any shape desired; and in length are about twice as long as the distance between each transversely opposite pair of standards in which they are mounted. The ends of the rods outside of the standards are connected by cross-heads 27, from the centers of which depend arms 28, said arms extending down the opposite sides of the frame 7, and are connected by upper and lower rack-

bars

29 and 30 respectively, that extend transversely through the frame 7. These rack-bars are arranged at opposite sides of the basket-pinion 22, and have: their teeth formed upon their inner sides so that each bar may be. engaged by the pinion by an alternate raising and lowering of the lat ter (see Fig. 4.) At their opposite ends the rack-bars are provided with plain untoothed portions 32, which when occupied by the basket pinion, permit of the latter running idly and without operating the rack-bar. The lower rack-bar is provided upon its front face with a series of teeth 33, Fig. 5 which engage and operate a gear-wheel 34, journaled as at 35, in the front end of the framework 7, upon a suitable cross-bar 36.

A tray 37 is secured in the front end of the frame 7, and in the same there is mounted for loose rotation a series of rollers 38, the faces of which are preferably covered by some textile or other material. In rear of the rollers there is secured to the opposite sides of the frame a series of cross-strips 39, Figs. 3, 4, and 7, which are bolted in position by bolts 40, and are located a slight distance apart. Any number of these cross-strips may be employed, in accordance with the number of brick that are to be cut simultaneously. Bolted to the cross-strips by the bolts 40 are pairs of opposite L-shaped standards 41, rising a short distance above the cross-strips. These standards are flanged at their upper ends, as shown, and are slotted at their lower ends, whereby they may be adjusted at proper distances apart. Each pair of standards is connected by an upper cross-piece 42, slotted near their ends as at 43, and adjustable upon the upper flanged ends of the standards through the medium of bolts 44. The upper cross-strips 42, the standards 41, and the lower cross-strips 39, are all alike arranged in groups or spaced from each other by narrow intervening spaces 45. (See Fig. 3.)

Sleeves 46 Fig. 2 are mounted upon each of the rods 25, and are designed to move with the rods. The sleeves are preferably adjustable, and are provided upon their upper sides with movable boxes 47, in which is journaled for rotation a transverse shaft 48. A series of in this instance three circular thin steel knives 49 are mounted upon the shaft 48 and by means of collars 50 are spaced apart so as to register with the narrow spaces 45 existing between the upper and lower cross-bars 42 and 39, and the standards 41; so that as the rods 25 reciprocate,'the cutters pass between the said upper and lower cross-strips and standards, and the latter containing a cake of clay serve as so many molds in which the series of bricks are formed by the passage of the cutters. The upper peripheries of the loose rolls 38 are about in the same plane with the lower cross-strips 39, and located between the rear roll of the series and the front crossstrip is a chute or reduced passage 51, Fig. 2 the opposite side-walls of which are inclined so that the clay is guided in a proper form into the brick-forming frames.

In rear of the pairs of standards 24, a pair of opposite parallel ways 52" are mounted upon the upper side of the frame 7; and outside of the ways a pairof transversely opposite standards 52 are located, said latter standards being slotted as at 53 Fig. 1 for the reception of bolts 54 by which the standards are longitudinally adjustable upon the frame 7.

In bearing-openings 55 Fig.9 formed in the upper ends of the standards 52, a transverse shaft- 56 is loosely mounted. This shaft is provided adjacent to one of the standards with a ratchet 57, Figs. 2 and 9 rigidly mounted upon the shaft, and a collar some distance from the ratchet also rigidly mounted upon the shaft.

Between the ratchet and collar a gear-wheel 58 is loosely mounted on the shaft, andat one side of the gear-wheel a disk 59 is likewise loosely mounted, but made rigid with'thegearwheel. A pawl 60 is pivoted to the disk and a spring 61 also secured to the disk serves as a means for pressing the operating end of the pawl yieldingly into engagement with the teeth of the ratchet-wheel. Near its center the shaft carries a radial rigid wing 62, Figs. 2 and 3 and at that end of the shaft opposite which the just previously described mechanism is located, and outside of its bearing, there is secured a weighted crank-arm 63, Figs. 1 and 2 upon which a weight 64 is adjustably mounted, and also a shoulder 65, the latter being designed to engage and interlock with a spring-catch 66 slotted and made adjustable by means of a bolt 67 which serves as an attaching means to the adjacent standard 52. At the inner side of the standard 52 just mentioned, an arm 68 Fig. 2 is located, and adapted to revolve with the shaft 56, said arm having its free end beveled, whereby it is adapted to engage with the notched end 69 of a lever or catch 70, Fig. 3 pivoted as at 71 to the inner side of the said standard 52.

In bearing brackets 73, extending rearwardly from the rear pair of standards 24, a roek-shaft 74 is mounted, and the same is provided with a pair of forwardly-disposed pins 75, and 76, located near the right and left-hand ends respectively of the said rockshaft, and in the path of the opposite beveled faces of a trip-lug 77, depending from the inner bearing-sleeve 46. A rock-arm 78 Fig. 3 also extends from the shaft 74, though disposed rearwardly,.and its free end is loosely connected by a link 79 to the free or front end of the catch-lug 70, the endsof the link being pivoted to the rock-arm 78 and catchlever 70, as indicated at 80. A coiled spring 81 is connected to the rock-arm 78 near its free end, the opposite end of said spring being connected to the sides of the frame 7. By means of this spring 81 the pins 75 and 76 are normally maintained in the path of the trip-lug 77, and the rear or shouldered end of the catch lever is maintained elevated in the path of the free end of the arm 68. Mounted for movement in the Ways 52 is a table 82, the same being provided at one side with a pair of standards 83, Figs. 4 and 9 longitudinally opposite each other and supporting a rack-bar 84, the teeth of which are upon the upper side of the bar, engage with and operate the gear-wheel of the transverse reciprocated thereover, for a portion of its movement. In the side-bars is journaled a series of loose rollers 86, and over the same an endless apron 87 passes.

A shaft 88, Figs. 5 and 10, passes transversely through and is journaled in the frame 3, in rear of the slotted standard 1 1, theinner end of the shaft being supported by a bar 89 of the frame 3; and between the outer side of the frame and the bar 89 there is mounted upon the shaft a ratchet-wheel 90, which wheel is fast upon the shaft. At one side of the rachet-wheel a disk 91 is loosely mounted upon the shaft, said disk being provided upon its outer side with a gear-wheel 92 likewise loose upon the shaft but fast upon the disk. Upon the opposite side of the disk'a pawl 93 is pivoted, and by a spring 94 the free end of the pawl is maintained in operative engagement with the teeth of the ratch et-wheel 90. Outside of the frame 3 a gear-wheel 94B is mounted upon the shaft, and also a disk 95. In front of the disk there is pivoted to a bracket 96, as at 97, a head 98, from which extends rearwardlya pair of rods 99, the rear ends of the rods being connected by a head 100, having a central perforation. A plunger-rod 101 is connected bya wrist-pin 102 to the outer face of the disk 95, passes through the perforation in the head 100, and is connected to the center of a head 103, provided near its ends with perforations for the reception'of the rods 99 upon which the head 103 is adapted to reciprocate. A coiled spring 104 is mounted upon the plunger-rod 101 and is interposed between the heads 100 and 103. These parts constitute a yielding extensible pitman, and as a spring connection for aid ing in the rotation of the disk 95 and consequently the shaft 88. (See Figs. 1 to 5.)

In the side of the frame and the bar 89, immediately in front of the shaft 88, a second transverse shaft 105 Fig. 5 is journaled, and upon the outer end of the shaft a gear 106 is located, said gear engaging with the gear 949 of the shaft 88. Upon the inner end of the shaft 105 a disk 107 is mounted, and the same by a wrist-pin 108 is connected by a pitman 109 to an L-shaped pin 110, projecting from the vibrating lever or arm 18.

From the opposite sides and the bottom of the table 82 depend brackets 111, and in the same are pivoted depending arms 112, the same being connected at their lower ends by a cross-bar or rod 113 Fig. 3. Depending from the center of the rod 113 and rigid therewith, is a lever 114C, to the lower end of which is pivoted, by a bolt 115, adjustable in anyone of the holes in the lower end of the lever,

a fulcrum-bar 116, the front end of which is pivoted as at 117, to a depending standard 118, the upper end of which is secured to the underside of the cross-bar 30 of the frame 7. A coiled-spring 119 has its rear end connected to the bolt 115, and its front end to an adj usting-rod 120, the front end of which is threaded and projects through an opening 121 formed in the front end of the frame 2 and is there provided with a nut 122. By manipulating the nut upon the rod the tension of the spring may be regulated or decreased, as may be desired. To a wrist-pin 123, projecting from the under-side or face of the gear-wheel 34 is pivoted the front end of a pitman 124, the rear end of which is flexibly and pivotally connected to a bolt 125 by means of a pair of straps 126, perforated and engaging pins 127, which extend from the opposite side of a cylindrical block 128, pivotally mounted on the bolt. This completes the construction, with the exception of a series of keepers 129, Fig.

4 which aresecured to the sides of the frame 7, and depend under and loosely engage with the longitudinal side-bars of the supportingframe 3.

This being the construction, the operation is as follows:The tray 37 containing the rollers 38 is filled with water or oil, which is absorbed by the surfaces of the rollers which become thus coated and slightly non-adhesive. The machine being set in motion, the clay is conducted from the die of the brick machine in a long blank, is forced by the machine over the rollers through the chute at the front end of the machine, and into the brick-frames between which the rotary knives are to run. When this has been accomplished, the frame 7 is pushed to the rear by hand, so as to ride upon the loose wheels and the

tracks

6 and 4. respectively. Such movement of the frame through the medium of a rack-bar 130, causes a rotation of the gear 92, the disk 94. and the ratchet-wheel 90, the latter through the medium of the pawl of the disk that is engaged with the ratchet wheel. Such movement upon the part of the shaft 88 rotates the disk 95 one half against the tension of the spring 104 of the pitman, and the remaining half or return of the pitman is caused by the tensile force of said spring. Hence the object of employing the extensible pitman is to obviate the necessity of moving the frame 7 too long a distance. The rotation of the shaft 88 is imparted to the gear 106, and the latter rotates the shaft 105, the disk 107 and through the medium of the connecting-rod 109, vibrating the bar 18 in one direction. Such vibrations of the rod serve to shift or throw the basket-gear into operative engagement with either the teeth of the upper or lower rack-

bars

29 or 30 in accordance with the movement given the shaft 20, and such movement is permissible upon the IIO part of said shaft by reason of the gimbalgagement and is rotated by its shaft, which as before stated is in operative connection with a suitable motor, as the engine that runs the brick-machine, or the brick-machine itself, it serves to reciprocate transversely the cutter-carrying frame the cutters passing through the lump of clay contained within the brick frames and cutting the same into bricks. chine is preferably made by hand, as before stated; but whether it is reciprocated by hand or means hereinafter described, the large coiled spring 119 serves to retract the frame. the incoming clay pressing against the rear end brick of the series forces said series to the rear against the delivery-table 82, and pressing against the wing 62, located above the table, serves to reciprocate the frame 7, and in the manner heretofore described shift the basket-gear, which has in the meantime been runningidly,into engagement with the opposite rack-bar; so that the cutters traverse in the opposite direction,

making the second cut. As the cutters begin to traverse, the trip-lug 77 has come into contact with the adjacent pin 75 or 76 whichever it may be, and thus the shaft 74 is rocked against the tension of the spring 81 and through the medium of the link 79 the rear end of the catch-lever is elevated so as to liberate the arm 68, and the wing 62. At this point the weight 64 dropping to a vertical position elevates the wing slightly and the delivery-table 82 makes its rearward movement, its rack-bar 84 serving to entirely rotate the shaft 56 and the wing 62, and throw the parts into locked position behind the bricks on the table 82. By the return of table 82 the bricks being on the rear side of the locked wing 62, are deposited upon the endless belt 87, and in its return rotates the gear 58 of the shaft 56 but the latter being loose on said shaft and only operating with it in one direction, does not influence the shaft, its pawl riding lightly over the ratchet wheel 57. The cutters having now passed out of the lump of clay, the freshly cut bricks are forced on the table 82, partly by the return of frame 7 caused by the tension of spring 119, and partly by the oncoming blank of clay. The rearward reciprocation and return of the delivery table is accomplished through the medium of the pitman 124, which is operated by the revolutions of the gear-wheel 34, and it in turn is operated by the side teeth of the lower rack-bar 30. It will be understood that these mechanisms are properly timed so as to combine and relatively operate at proper steps of the operation of the machine, and it will also be observed that for the purpose of facilitating such proper timing most of the parts are made adjustable.

From the foregoing description, taken in connection with the accompanying drawings, it will be seen that I have provided a machine of simple construction, that is adapted to sue- The first reciprocation of the man The bricks having been cut and cessively, accurately and rapidly cut series of bricks, the action of the machine leaving no rough edges or other objectionable features to indicate that the brick has thus been manufactured. It will be seen that the machine is entirely automatic in its operation, in that the cutting of one set of brick and their forward movement serves to throw the mechanism into operative connection in areverse manner, and thus repeat the cutting, and so on. After the delivery of the brick the basket occupies the untoothed spaces of the rack-bars, and runs idly; so that no unnecessary wear of the mechanism takes place. The brick after formation may be taken from the endless belt and placed upon trucks to be run into kilns for the purpose of burning, or if preferred the endless belt may extend into suitable drying-chambers through which the brick may be conducted.

I do not limit my invention to the exact details of construction herein shown and described, as many changes not seriously affecting the construction thereof will no doubt suggest themselves; and I therefore deem such variations of details as within the scope of myinvention.
