ErKLoR, AND CHARLES vWILLIAM GRANT,4 OF URBANA, ILLINOIS; SAID EIKLOR AND GRANT ASSIGN- ORS TO SAID LEMING.
MoLDlNG-MACHIN.
To' aZZ whaha tima/y concern: `Be it known that we, PARMENOS GRANT LMING, FRED VEIKLOR, land CHARLES WIL- LIAM GRANT., citizens of the United States, and residents of Urbana, in the county of Champaign and State of Illinois, have invented a new and Improved Molding Machine, of which the following is a full, clear, and exact description.
Our invention relates to a machine for molding purposes, and is es ecially applicable forpthe vmanufacture o hollow cement building-blocks, although it is capable of general use for molding plastic materials.
Our invention comprises a hand-operated machine provided with an automatic coreeXtractor and means whereby the molded article can be readily transferred from molding positionto a pallet and released from the mold in a rapid and efficient manner.
Refererxice is to be had to the accompanying drawings, forming a part of tliisspecification, in which similar characters of-ireference indicate corresponding parts in all the fig- 'Figure 1 is a perspective view of a machine constructed in accordance with the principle of our'invention. Fig. 2 is a longitudinal -sectional view thereof on the line 2 2 of Fig. 3.
Fig. 3 is a sectional view on the line 3 3 of Fig. 2, and. Fig. 4 is a perspective view of a portion of the end of a mold which may constitute a part of the machine.
The machine is provided with a frame l()H .providedwvitliasupport 11 for a tamping-siii` 1,2. This ltamping-sill in our preferred form 'is raised above the main part of the frame agi height substantially e ual to the heights of-L the mold which is emp oyed but this is a de- 16, which 1s preferably pivoted to these suptail that can be departed from. The main frame extends to the right for some distance and is provided with a pallet-silli13.. These two sills are located' at opposite ends of the" Uframe,'and midway between them are placed one or Vmore supports 14 for a movable frame Orts by means of a shaft or rod 16. The arme 15 is shown as comprising two bars extending from the rod 16 in the same direction and provided withhandles 17 at their-ends Specification of Letters Patent.
Application filed May 6, 1905. Serial No. 259,113.
as shown in Fig. 2.
Patented Feb. 27, 1906. v
by means of which the device can be manipulated. The frame is provided with a moldplate 1 8, which virtually constitutes the bottom plate of the mold. To this plate are secured spring-hinges 19, which are so constructed as to normally hold the several moldwalls 20 .in open position, as indicated in dotted lines in Figs. 2 and 3. Upon two opposite walls 2O are pivoted locking-bars 21, having oppositely-disposed notches 22 for engaglpment with lugs 23 upon the other moldwa s.
It will be readily observed that when the locking-bars are moved into the position shown in Fig. 4 all of the mold-Walls will spring outwardly into the position shown in dotted lines. These parts constitute the main portion of the mold; but it is preferably provided with other features, especially one or more cores 251. These cores are adapted to project through an opening 25 in the moldplate 18, so as tov enter the mold in an obvious manner. They are made in any desired shape, but are preferably tapered to facilitate drawing through the mold-plate. These cores are pivotally or otherwise movably connected with core-moving bars 26, which are pivoted upon the shaft 16 and are provided witl; extensions 27, adapted to engage'the under side of the tamping-sill 12 when the frame 15 is swung over into reverse position, The projections 27 may conveniently be provided with steel plates 28 to prevent excessive wear. A pallet 29 is vI preferably pioifided.
. The operati onlof'the device will now be described. The frame 1-5 ,`,fcarrying the cores 24 in the proper;A position infthe mold, is first placed on the tampingsill, and with the' mold walls fixed in Ca closed position the molding material is' placed in the mold and tainped.' The pallet is then placed on top of fthe mold, if desired, and the operator by grasping the handles 17n turns the whole frame over, upon its pivot and deposits the molded bleek and pallet upon the pallet-sill 13, or in certain kinds of molding the pallet can be left upon the pallet-sill and the mold deposited on that directly. As the frame' 15 approaches the position in which the mold rco with respect to the mold. The continued ro out from the molded article, and even if promotion oi the mold and frame therefore draws the cores from the molded article. If they arms 2,1 are now moved into the position shown in Fig. 4, the mold-walls will spring vided with roughened or figured mold-surfaces they will leave the article and thereby free it fromthe mold. The frame 15 is now turned back to position on the tamping-sill ,15 and the molded article is left in the position shown in Fig. 1.
` A machine constructed in accordance with rthe principle of this invention is exceedingly simple and can be manipulated by a single zo operator with great eHiciency and rapidity.
The blocks or other objects molded are left in the exact state in which the mold is designed to leave them without any marring of' the surfaces, and the delivery of the product from the mold is rendered absolutely certain and very rapid. The mold is also restored to position Jfor another operation with a minimum of trouble and a very small expenditure of energy.
Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1. l A block-molding machine having a pivoted frame, a mold thereon at a distance from the pivot of the frame, and two sills located at a distance from the pivot ol" the frame equivalent to the distance between the pivot and mold. l
2. A block-molding machine having a pivoted Jframe, a mold thereon at a distance from the pivot of the frame, and two sills located at a distance from the pivot of the frame equivalent to the distance between the pivot and mold and on opposite sides of the pivot, whereby the frame is capable of carrying the mold from one sill to the other.
3. In a molding-machine, the combination of two sills, a frame pivoted at a point midway between them, a mold on the frame, a core, and means for automatically drawing the core from the mold when the frame is swung about its pivot.
4. In a molding-machine, the combination of two sills, a frame pivoted at a point midway between them, a mold on the frame, a core, and means for automatically drawing the core from the mold when the frame is swung about its pivot toward one sill; said means being constructed and adapted to operate before the mold reaches that sill.
5. In a molding-machine, the combination of two sills, a frame pivoted at a point midway between them, a mold on the frame, a core, and means for automatically drawing the core from the mold when the frame is swung about its ivot; said mold having separable walls, an spring-hinges by which the walls are connected to the main part of the mold. p
