MACHlN E FOR MOLDING PLASTIC BLOCKS.
SPECIFICATION formingpart of Letters Patent No. 792,151, dated June 13, 1905.
Application filed May 19, 1904. Serial No. 208,710-
To all whom it may concern:
Be it known that I, JosErH M. MoDowELL, a citizen of the United States, residing at O0- lumbus, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in Machines for Molding Plastic Blocks, of which the following is a specification.
My invention relates to a new and useful improvement in machines for molding plastic blocks.
The object of the invention is to provide a superior means whereby the block may be readily discharged from the machine and through which means the liability of cracking and chipping the block through excessive handling is obviated.
Finally, the object of the invention is to provide a device of the character described that will be strong, durable, and efficient, and comparatively simple and inexpensive to manufacture and one in which the several parts will not be liable to get out of working order.
WViththe above and other objects in view the invention consists of the novel details of construction and operation, a preferable embodiment of which is described in the specification and illustrated in the drawings, where- 1n- Figure 1 is an end elevation of the machine. Fig. 2 is a top plan view of the machine. Fig. 3 is a vertical section, and Fig. 4 is a front elevation showing the mold-box in its inverted position.
In the drawings the numeral 1 represents the frame, which comprises end standards 2. Supported in bearing-boxes 3 on the upper ends of the standards are trunnions 4, which have keyed on their outer ends the elongated hubs 6 of the gears 7, each of which meshes with a pinion 8, mounted on a stub-shaft 9, supported from the standard 2 and connected with an operating-crank 10, by the rotation of which the trunnion 4 is revolved through the pinion 8 and gear 9. The inner ends of the trunnions 4 project from the bearingboxes 3 and have keyed thereon the brackets 11. The brackets have bolted on their lower horizontal portions the opposite ends of a suitable bed-plate 12. The bed-plate 12 fixedly supports a pair of upright tapering hollow cores 13, about which is disposed a pallet 14, which rests upon the bed-plate and is provided with downwardly-projecting lugs 15, by which it is secured in place. Hinge-lugs 16 are formed on the bed-plate along its sides and ends. End doors 17, having hinge-lugs 18 registering with the hinge-lugs 16, are disposed at each end of the bed-plate. Rods 19 passing through the hinge lugs also pass through the lugs 15 of the pallet, thus pivotally securing the doors and fixedly holding the pallet in place. lugs 21 pivotally connected with the hingelugs 16, whereby the said side doors may be swung outwardly.
It will be observed that when either of the cranks 10 is turned, thus setting the pinion 8 and gear 7 in motion, the brackets 11, supporting the bed-plate and the doors, which may be termed the mold-box, are swung Side doors 20 have hingeoutward and upward, thereby inverting the mold-box, causing it to assume the position shown in Fig. 4., from which position the block may be discharged by manipulating the handle 32 to swing the doors 17 and 20 outwardly.
In order to receive the block and prevent jarring of the same in the discharge, a platform 33 is provided. The platform is supported upon the inwardly-projecting arms 3%" Of course it is to be understood that after themold-box is swung tothe inverted-position.
and before the doors are pulled-outward the platform is raised, so as'to prevent the block from falling from -the-box,andthereby being damaged. hen the platformlias been raised, the'doors are pulled outward,.,as heretofore described, thus discharging the molded block on the platform, which is then lowered to-the position shown in Fig. 4, from which pointit.
may be readily removed to-a suitable truck, which preferably would have a height equal to the lowered position of the platform, so that the block might be readily shoved from the platform onto the truck andremoved from the machine. The mold-box being returned to its normal position and the doors closed, material is placed therein and the process of molding the blocks continued.
Itis apparent that an expeditious means for discharging the blockis provided and that .the liability of damaging the block is greatly obviated. By such an arrangement much time may be saved over other methods in which it has been the practice to remove'the block from mold-box by means of grapples and the I do not wish to limit myself to the exact details of construction and operation herein set forth, as Imay make various changes in the same without departing from the spirit of my invention.
Havingnow fully described myinvention, what I claim, and desire to secure by Letters Patent, is-
1. In a machine for molding plastic blocks, the combinationawith supports,ofan invertible frame pivotally mounted upon the supports, fixed cores associated with the frame, a moldbox arranged'about the cores having side and end doors hinged adjacent to its bottom, means for inverting the frame and mold-box, and means for opening the doors outward when the mold-box and'frame have been inverted.
2. In a machine of the type set forth, the combination with a' frame, of an invertible mold-box providedwith fixed cores and having hinged side-and end doors, means for moving said doors outward; means for inverting said mold-box, and a vertically-movable platform associated with said mold-box and frame for delivering the molded blocks.
3. In a machine for molding plastic blocks, the combination Withsupports, of a frame-pivotally mounted upon the supports, cores associated with the frame, a moldbox having hinged end and side doors arranged aboutthe cores, and mechanism for opening the doors comprising shafts rotatably connected together and also connectedto the doors.
4:. Inamachine of the type set forth, the combination with a frame, of an invertible mold-box having hinged side andend doors, means for moving said doors, means for inverting said mold-box, a vertically-movable platform mounted on said frame, and means for moving said platform.
5. ha machine of the type set forth, the combination with a frame having guideways, of brackets swingingly mounted upon the frame, a mold-box having fixed cores and. hinged side and end doors supported upon'the brackets, means for moving said doors also supported from the brackets, means for swinging the brackets, sliding blocks mounted in the guideways of the frame, a platform supported by the blocks, and means for moving the blocks.
