Filed lune 27, Bull, er. No. 291,334 '7 Claims. (6i. 125-23} This invention relates to improvements in brick cutters and the like, and more particularly to a manually powered brick cutter for cutting bricks or other masonry like members such as concrete blocks and certain stones.
Various cutters have been proposed heretofore for performing such functions, but these for the most part were cumbersome and bulky, and complex in structure to perform the function intended.
The present device is so constructed that it may be readily dismantled for carrying from place to place and may be readily reassembled in a minimum of time to perform brick, stone, and masonry cutting operations, which operations heretofore required large stationary machines.
An object of this invention is to provide a device for cutting brick and the like, which device is readily adjustable to cut blocks of masonry within a wide range of dimensions.
Another object of the invention is to provide a brick cutter and the like for cutting blocks of masonry, which device is manually operated, and which exerts high cleavage pressure between two opposed masonry cutting knives.
Still another object of the invention is to provide a masonry cutting device which supports the block of masonry above the lowermost knife to enable the block to be freely slid thereover until correctly positioned.
Still a further object of the invention is to provide a masonry cutting device which is lever operated, the pressure on the knives of which is progressively increased as the knives bite into the masonry block.
Still a further object of the invention is to provide an adjustment member to readily vary the distance between the knives preparatory to the cutting of the masonry block.
Still a further object of the invention is to provide a gauging device to enable the masonry blocks to be readily gauged for length without the use of ancillary measuring devices.
Yet another object of the invention is to provide a masonry cutter which is accessible from the front and from each side.
With these objects in mind and others which will become manifest as the description proceeds, reference is to be had to the accompanying drawings in which like reference characters designate like parts in the several views thereof, in which:
FIG. 1 is a perspective view showing a front and a side and top of the device with the upper knife being shown in raised position;
FIG. 2 is a front elevational view of the device, showing the knife in a similar position to that shown in FIG. 1;
FIG. 3 is an enlarged, fragmentary, front elevational view of the cutter actuating mechanism, with parts broken away and shown in section, with the masonry block supporting table shown in full outline in normal position and dashed outline in depressed position;
FIG. 4 is a side elevational view showing one position of the masonry block cutter in full outline and showing the masonry cutter in dashed outline in a raised position;
FIG. 5 shows the detachable cutter portion of the masonry block cutter device removed from the supporting stand;
FIG. 6 is a detailed view, partly in section, of other mechanisms to actuate the cutter knife;
FIG. 7 is a sectional view taken on the line 77 of FIG. 6, looking in the direction indicated by the arrows; and
FIG. 8 is a sectional view taken on line 3-8 of FIG. 6, looking in the direction indicated by the arrows.
With more detailed reference to the drawing, numeral 1 designates generally a supporting stand for the masonry cutter device. The numeral 2 designates generally a masonry cutting device which is attachably connected to the stand 1 by a clamp screw 4, which clamp screw bindingly engages the lower surface of stationary table 6 with the upper face of support stand 1 when tightened, or the masonry cutting device 2 may be removed from the support stand 1 as indicated in FIG. 5, whereby the masonry cutting device may be attached to a suitable work bench, if desired. The support stand 1 preferably has a rectangular top member 8 welded or otherwise secured together to form a rectangular member to which legs in of the support stand are secured as by welding. The legs 1t? diverge downwardly and outwardly and braces 12 maintain the legs in spaced apart relation, and each leg It? has a support pad 1-5 on the lower end thereof.
A pair of wheels is provided, one of which wheels is secured on each of a pair of adjacent legs id, as will best be seen in FIGS. 1 and 4, so that the wheels 14 will be spaced above the lower face of support pads 16 on the lower end of the respective legs it so that the support stand ll will be stable during use, and which may be tilted onto the wheels for movement from place to place. The masonry cutting device 2, as illustrated in FIG. 5, may be readily placed in a car, pickup truck or the like, as can the support stand 1, for transportation from place to place.
The masonry cutting device 2 has a stationary table 6 forming a base which is welded or otherwise secured to an upstanding standard 13 with the base serving as an abutment to seat on the upper surface of rectangular top member 8. An arm 24? is secured near the end of the standard 13 and extends beneath the rectangular top member 8 and has a clamp screw 4 extending there through, which clamp screw bindingly engages the upper surface of rectangular top member 8 with the lower surface of stationary table 6. The stationary table or base 6 is a ertured with spaced apart apertures to receive headed pins 24 therethrough, which pins extend upward and are welded or otherwise secured to a divided, movable support table 26, which table 26 is supported on a plurality of compression springs 28 so as to normally hold the upper face of the movable support table 26 in a plane which is normally above the edge of the masonry cutting blade 34 mounted in support bar 32 on stationary table 6. in this manner, masonry may be moved over movable support table 26 without injuring the cutting edge of blade 3% The pins 24 each have a head or an abutment 34 on the lower end thereof to engage the lower side of stationary table 6 when the movable support table 26 is in the uppermost position under the influence of compression springs 28. A compression spring 28 surrounds each pin 24, as will best be seen in FIG. 3.
The movable support table 26 has a guide 3:: secured along a portion of the rear side thereof, which guide 36 indicia thereon, as will best be seen in FIG. 3, whereby an exact measurement of the masonry being cut can be determined prior to the cutting thereof. Furthermore, a stop 38 is provided on the guide 36 to enable the stop to be set at a predetermined position for cutting members of masonry into identical lengths.
The upstanding standard 18 has a tubular member 40 telescoped downward thereover, as will best be seen in FlG. 6. The upstanding standard 18 has a longitudinal keyway 42 therein to receive a key 44, which key projects upper end of tubular member 40 has an apertured cap 1 50 on the upper end thereof, which aperture is of a size to permit passage of screw threaded member .4 8 down- Ward therethrough. The, screw threaded member 48 has an annular recess 52 therearound to receive a pair of complementary U-shaped'retain-ing Washers 54 therein, which washers extend outward and are secured in place by a removable cap 56, through which cap 56 bolts 58 pass to bindingly engage the U-shaped washers 54 against longitudinal movement with respect to tubular member 46. A crank 60 is fixedly secured to the upper end of screw threaded member 4-8 to enable the turning of screw threaded member 48, which will move the-tubular member 40 relative to the upstanding standard 18.
A pair of spaced apart, outstanding brackets 62 is secured to the side of tubular member 40, each of which I brackets has an outwardly extending apertured lug'64 thereon to complementary receive an apertured member 66 .therebetween, one of which apertures registers with apertures in lug 64 to enable a'pin 68 to be passed therethrough. A further aperture is formed in member 66 and is spaced apart from pin 68 and registers with apertures in the upper end of a pair of linkages 70 in such manner as toenable a pin 72 to be passed through the apertures in linkages '70 and the further aperture in member 66. A movable knife .or cutter blade 74 is mounted, in sliding relation, between the pair of brackets 62, as will best be seen in FIGS. 6 and 7. The knife or cutter blade 74 is of a length to cut a masonry block the desired width and has an upstanding leg 76 thereon with an inturned arm 73. A bar 7 9 passes transversely through the spaced apart pair of brackets 62 and is removably secured therein and preferably has a spring retaining seat 80 on the upper face thereof, which is in aligned relation with a spring seat 82' on the upper face of arm 73; A web 86 extends between and is secured to spaced apart, outstanding brackets .62 to form a rigid brace therefor. A spring 84 is interposed between spring seats 89 and 82 and is in suflicient compression to cause the blade 74, arm 78, and a handle 96 to be raised, so the upper face of arm. 78 will abut with a face of web 86 to limit the upward movement of the blade 74. The outer face of upstanding leg 76 is in sliding relation with the inner face of a plate 88 which extends between slide brackets 62. The inner end of arm 78, as indicated at 90, is in sliding relation with the side of tubular member 40 so as to hold the blade 74- in true guided relation. 1
The blade support member 73 has an aperture 92 therethrough. The linkages 70 are apertured on their lower end to complementally register with the aperture 92 in the blade support member 73 to enable a pin 94 to v be passed therethrough to enable the blade support member 73 and the blade 74 to be moved upward and downward upon movement of the lever 96, which extends outward from member 66, which has a socket 93 therein to enable the lever 96to be inserted thereinto and removed therefrom. The angularity of the apertures in member 66 is such that, when the lever 96 is moved to urge blade 74 downward, the pins 68, 72, and 94 become morenearly The height of the movable cutter blade 74 may be varied relative .to stationary cutter blade by turning the crank 60 to either raise or lower the tubular member which carries the movable cutter blade 74 in the manner set out above.
. Operation By having the movable support table 26 supported on compression springs 28, a block of masonry may be placed thereon and moved therealong until the cutting edge of movable cutter blade 74 is directly above the portion of the masonry block to be cut, and with the tubular member 40 adjusted vertically by crank 60 until the cutting edge of the blade 74 is directly above the masonry to .be cut, the lever 96 is then moved downward, and as pin 72 approaches a straight line with pins 68 and 94, the maximum pressure of the cutter blade 74 is exerted on the masonry block, such as indicated at B, Which will cause a cleavage of the masonry. However, if the cutting edge of blade 74 cuts into the stone and the stone or masonry block does not shear or cleave, the crank 6d may be turned to screw the screw threaded member 48 in such manner as to lower the blade 74, whereupon a further action of the movable blade 74 may be had without removing the masonry from the movable support table '26.
It is to be pointed out that the device is easy to assemble and disassemble, that it is easyto removethe blades 30 and 74 by looseningscrews 100 and 102, respectively.
aligned to present a lever power that approaches or attains toggle action at the point Where it is necessary to apply the greatest pressure to the masonry being out. However, upon release of pressure, the spring 84 will return the lever 96 to the uppermost position to receive subsequent masonry pieces, such as bricks, concrete blocks, stones and the like thereunder for successive actions by the cutter blade 74 thereupon.
v by Letters Patent is:
Furthermore, the screw'threaded member 48 may be readilyremoved' by removing bolts 58, removable cap 56, and U-shaped washers 54. The various parts may be readily replaced and removed when they become worn.
