ence to manually operated brick making ina chines, that is to say," machines of the type which are manipulated "by hand. I
The primary objectof this invention is to provide a hand operated devicevfor making bricks or blocks which is characterized by the fact that as the'outer sides orwalls of the moldas well as anydivision. web or webs-are simultaneously drawn upwards away from the aggregate the pressure or force caused by the weight of said mold is thrust directly and evenly over the upper surface of the green aggregate. f i Another object ofmy invention is to provide an improved hand operated device. for making bricks having a series of divisions each of which contains a. number of cores, whereby bricks are produced which can be, brokenwwith facility at any desired position for filling odd spaces or completing lines of masonry work.
A further object, of this invention is the provision of ,afbrick making device by theuse which apertur'ed bricks are produced which readily lend themselves to interlocking connection wvlienbonded together either 'bythe use of ordinary mortar or by grouting, reinforced or otherwise. 7
Aetill fnrtherobect attained by th1s 111,-
vention is the provision of brick making device capable of turning out bricksofdif ferent density or porosity, and incidentally due to their apertured formation ofqrela tively less weight. Another ob ect a bridging frame having supporting legs whichwhen the flask :portionis raised to liberatethe molded. aggregate or -bricks, serve to prevent said aggregate or bricks from being crushed out of shape by the downward thrust exerted when lifting said flask and the friction ofits walls thereagainst. i A
Still further objects resulting'from my invention areeconomy inmalterial and producdischarging attained by my invention is consequent upon providing the mold w th;
t rs stion costs whilst :labor expense in building is correspondingly reduced.
With the foregoing and with bricks produced by'in y improved means other objects in view as will belmore apparent fromt-he following disclosure,this invention consists essentially in certain, novel features of construction, combinations and arrangements of :parts hereinafter fullydescribed, and-more specifically defined by the appended claims. In the further disclosure of the invention reference is to be had to the accompanying 1 sheets of explanatory drawings illustrating one practical embodiment thereof, and in which drawings corresponding or like parts are designed by the same reference, characters. k 1 Figure 1is atop plan view of my im proved brick or'block formingdeviceflf Figure 2-is a side [elevation of the same with part broken away or in section for the sake of clearness, and the raised or brick position ;being; indicated by dotted lines.
device with and v Figure Al-i's a transverse section taken substantially on, tl1elinet lin the precedingFigure.
Referring more particularly to the views which as before'stated are illustrative of the operating handles removed one practical embodiment of my invention only, l construct a rectangular frame or flask!) of suitable material which is divided. by transverse walls or integral partitions .6 to
provide a seriesofmolds? of the requisite dimensions to produce-the desired size of bricks or blocks; For ease in description the longer or side walls of the frame or flask 5' are designated by the numeral 8 andzthe shorter or end walls by the numeral 9. Upset relative to and integral. with ,the side walls 8 I provi'dea series of spaced brackets 10, the'upper; ends whereofare bossed to provide journals for rods or shaftsll on which are loosely pivoted the operatinghandles 12,-later on more specifically described;
Disposedoutside each end wall 9jof the framejorfiask 5 are standards or-lcgs 1 3 which are overhung or lnwardly deflected at their upper parts 14: so thatthey repose over said endewalls 9, and integral with the upper ends thereof are downwardly curved arms 15 having flanged ends 16 for connection to the false lbottomiplatesl 'Z by countersink screws 80 Figure 8is a. bottom plan view ofthe" use flask 5.
Securely attached by countersink screws 21 to the underside of the aforesaid crosspiece or member 19 are spaced inner and outer cam- path frame members 22, 23 respectively, which. are likewise connected securely to the aforesaid false bottom plates 17 by screws 24: and thus it will be readily seen and clearly comprehended by those conversant with the art that the standards or legs 13, cross-piece or member 19, and campath frame members 22, 23 are all rigidly connected together, with the frame or flask 5 free to be moved relative thereto as here after explained. It is to be here particularly observed that the inner cam-path t frame members have a cut away or removed part indicated most clearly in Figure 4: by the numeral 25 whereby a slight reduction in weight results. v
Disposed longitudinally of the aforesaid frame or flask-5 and seating on the inner edges thereof is what 1 term a multiple coregrid 26 having a plurality of integrally formed core pieces 27 of appropriate cross section to produce correspondingly shaped holes or apertures through the bricks or blocks produced by my novel molding device. This multiple core-grid 26 is conveniently clamped to the outer face of the frame or flask end walls 9, 9 by means of screw 28 passed through ears 29 on said grid threading into correspondingly screwed v holes provided for their reception, and it will also be noted that the core-pieces 27 are slightly tapered to ensure an easy draft when the frame or flask is withdrawn from off the finished aggregate.
Referring back againto the operating handles 12 it will be observed that each said handle is of what may be conveniently termed inverted knee-shaped pattern in side view and that they each comprise a handgrip portion 30 integral with spaced limbs 31; each of said limbs terniiinating in parallel curved forked members 32 through a which are passed the aforesaid rods or-shafts 11. The free ends of these forked members 32 are slotted at '33Figure 2-to provide bearings for anti-friction rollers 34: adapted to traverse the hereinbefore described campath frame members 22, 2-3; and the axles S5 for'said rollers 34 are securely riveted or otherwise attached to side plates 36 removably connected to the forked members -32 by screws 37. Thus it will be readily seen u that by removing'the screws 37 the side plates 36, attached axles 35 and anti-friction rollers 34 can be easily taken out and replaced whenever desired, whilst a simple means is provided for the ready assembly and dismantling of the just described parts.
In use and assuming as shown that my improved brick or block forming device is for the making of three said bricks or blocks at one and the same time the position of said device will be as shown by Figure 3. In this position it will be obvious that the ma" terial or aggregate can be filled into the three molds 7 according to prevailing practice. The device is then inverted or turned bottom side up as shown by Figures 1 and 4t and in this position it will be supported by the foot pieces 39 of the standard. or legs 13. The operator now takes hold of the hand grips 30 and draws them upwardly and in wardly with an arcuate movement towards each other as shown by the dotted lines in Figure 2, said movement causing the antifriction rollers 3a to travel downwards in the cam-path frame members 23. This downward movement of the anti-friction rollers 34 due to the pivotal connection of their supporting forked members 32 rocking on the rods or shaft 11 will result in the uniform and bodily raising as a unit of the frame or flask 5 with its integrally connected partitions 6 and attached cores 27, whilst the false bottoms 17 will remain seated on the upper surface of the molded bricks or blocks. The entire device can now be drawn off upwardly from the finished bricks or blocks or otherwise removed clear of the same without any frictional disruption or disturbance to said bricks or blocks.
From the foregoing it will be seen that by my invention 1 have evolved a very prac tical and efiicient means for molding or forming bricks or blocks of any desired shape and configuration and 1 wish it here under stood that my device may be used as a rigid or stationary mold, in which case the flask walls, core grid, and false bottom plates will be upwardly drawn simultaneously free of the molded material. When the device is used in this manner the surfaces of the inner false bottoms will be faced with sponge rubber felt-fiber or other soft cushion materials finished off with a layer of sheet rubber, leather, oil-skin canvas or such 11on porous materials as desired that will act as a cushioning means to prevent the suction of aggregate to mould bottom when loaded and thereby preventing breaking or fracturing to the edges and corners of the moulded bricks or blocks so that the same will be discharged from the mould as a ISO ' whole. This method of discharging the agsaid cam paths whereby said rectangular plurality of core members for producing gregate is effected by the shock of the rigid legs 13 striking the unloading bed Withv force, the impact forces aggregate as mould is lifted, due ,to fiber and rubber 1 cushion which breaks the suction bond. y v
l/Vhilst there has been shown anddescribed one practical embodiment of my invention the same is not to be construed in any restricted sense, as it will be obvious the same is susceptible of many structural changes without departing from its essentialfeatures or method of operation; for example, the flask may be mechanically raised, inverted or transported, and the right is therefore here by reserved to make such variations and other combinations as fairly lie within the scope of the appended claims.
Having described my invention, what I claim as new and desire to secure by Letters Patent is: y
