WILLIAM MEYER, OF GLADBROOK, IOWA.

CEMENT-BLOGK-MAKING MACHINE.

Application filed February 23-, 1923. Serial No. 620,734.

of a novel machine for making the cement blocks shown and described in my allowed application Serial No. 505,299.

An important object is the provision of a machine of this character provided with lever operated means for withdrawing the cores and other lever operated means adapted to be subsequently operated to move the face plates away from the completed block whereby to permit removal of the block.

An additional object is the provision of a machine of this character which will be comparatively simple and inexpensive in manufacture, easy to operate, positive in action, durable in service and a general improvement in the art.

With the above and other objects and advantages in view the invention consists in the details of construction to be hereinafter more fully described and claimed and illustrated in the accompanying drawings, in which:

Figure 1 is a side elevation of the machine showing the parts in initial position and showing a pallet placed upon the supporting table,

Figure 2 is a top plan view,

Figure 3 is an end view,

Figure 4 is a longitudinal section showing the levers operated to bring the face plates against the pallet and to bring the cores in operative position,

' Figure 5 is a detail plan view showing the use of a partition plate for forming half blocks,

Figure 6 is a horizontal section showing the usual cores replaced by thin cores for making corner blocks,

Figure 7 is a detail view of one of the face plates,

Figure 8 is a detail cross section through the mounting for the lever connecting links, Figure 9 is a perspective view of a completed block.

Referring more particularly to the drawings the numeral 10 designates the top of a supporting table mounted on suitable legs 11, reinforced by transverse bars or braces 12 located'at any desired point found suit able. 'It is intended that the block to be built be formed upon a pallet 13 which is slidably disposed upon. the table top and which is preferably provided at its underside with cleats. 14: which extend transversely.

Secured upon the top of the table near the ends thereof are bearing members 15 through which are slida'ble rods 17 which have their inner ends passing through core plates 18 and terminating in reduced eXten sions 19 screwed into holes in face plates 20 which constitute the sides of the mold. ,The lower edges of these face plates are rabbeted at 21'for engagement upon the upper side edges of the pallet and the ends of the face plates are formed with grooves 22 which receive the side edges of end plates 23 which are carried by angular leaves 24: hinged at 25 at the sides of the table,

The side plates 20 are formed with openings 26 within which are slidably disposed core plugs 27 which are all connected, at each plate, by a plate 28 on which the core plates 18 are secured. By this construction it will be seen that by moving the plates 28 all the core plugs are moved with respect to the face plates and that by moving the rods 17 the face plates themselves are moved.-

The top of the enclosure formed by the side plates 20 and end plates 23 is adapted to be closed by a top plate 29. It should be stated that the active or inner faces of the side plates, end plates and the top of the pallet and underside of the top plate may be ridged, grooved or otherwise formed to give the finished bloclr the desired ornamental surface, but no restriction is 'made as to the exact configuration. I

Pivoted at 30 on the ends of longitudinal bars 31- carried by "the table structure are levers 32 and 33 equipped with grip released locking pawls 34 and 35 respectively which cO-Operate with notched segments 36 and 37. Each lever 33 has pivotally connected therewith at 38 a link 39 which is pivoted at 40 upon a bracket 11 carried by the adjacent face plate. Pivotally connect-V ed at l2 with each lever 32 is a link 43 which 44 carried by a cross bar 45 which is secured upon the outer ends of each pair of rods 17 by means of suitable nuts L6.

Instead of having the levers independently operable it is well to provide means whereby the action of the machine may be controlled from either side alone and to aceomplish this I provide a pair of levers 47 and 48 pivoted at 49 on one or more brackets 50 rising from the center of the supporting frame. The levers 33 have connected there With, links which are pivotally connected by the pivots 51 and 52 with the upper and lower ends of the lever 4E7. Pivotally connected at. 53 with the levers 32 are links 54: which are pivotally connected at 55 with the upper and lower ends of the lever 48. The locking pawls are operated by squeezing grips 32 and 33 on the levers 32 and 33 respectively. When a grip is squeezed toward its associated lever it is apparent that the locking pawl will be drawn from the notched segment. Carried by the levers are loops 32 and 33 which, are adapted to be engaged with the grips for holding the pawls at either side of the machine out of engagement with the notched segments so that by moving the levers at the other side of the machine the levers at both sides may be simultaneously operated. Probably a right handed operator would engage the loops over the grips of the levers on the left side of the machine while a left handed operatorwould engage the loops over the grips at the right side of the machine; 7

In theioperation the pallet is placed upon the table at the center thereof, the end plates 23 are swung up into vertical position and the-levers 32, or one thereof, are swung to move the rods 17 toward each other and consequently bring the face plates 20 against thepallet. The rabbets 21 on the face plates and 23 on the end plates engage the pallet and center it properly. One or both levers 33 may then be swung to move all the core plugs through the openings in the face plates until they meet at the center of the form. The levers are locked in .their proper positions bythe grip released latch devices disclosed. The plastic material is then poured into the mold and tamped down, after which the top plate 29 is applied for properly forming the top of the block. Subsequently to this, the top plate is removed, the levers 33 are gripped to effect release of the locking pawls and are pulled outwardly to remove the core plugs from the finished block, the levers 32 arethen gripped to release the pawls and moved outwardly to withdraw the face plates from engagement with the block, and the end plates 23 are swung down wardly and outwardly, which will leave the pallet and the block thereon entirely free so thatthe block may be removed from thetable and-placed at some desired point for dry ing. Qbyiously, the grips at one side ofthe machine must be held by the loops or some equivalent device as explained above to permit the operation of all the levers from one side of the machine.

lVhen it is desired to make half blocks, I make use of a partition plate 56 which is located at the center of the form and which enables two half blocks to be made at one time.

When making corner blocks, in which instance the holes through the major portion of the block are undesired, I remove four of the core plugs at one end of the block and replace them with small plugs 57 which are of a thickness equal only to the thickness of the face plates and which are for the purpose, merely, of closing the openings in the face plates so that the sides of the completed block will be purely flush.

From the foregoing description and a study of the drawings it will be apparent that I have thus provided a simply eonstrueted and consequently inexpensive machine which will eflicieutly operate to make cement blocks of various kinds in addition to the specific form of block disclosed in my above mentioned allowed application, it being of course apparent that various modifications may be resorted to to widen the field of adaptability and scope of utility of the device, provided such variations constitute no departure from the spirit of the invention or the scope of the claims.

Having thus described my invention I claim:

1. In a block machine, a supporting table adapted to carry a pallet, pairs of bearing members mounted upon the table, rods slidable through said bearing members and having their outer ends connected, face plates carried by the inner ends of said rods, end plates hinged upon the sides of the table and adapted to be received between the face plates, said face plates being formed with openings, and a plurality of core plugs slidably mounted through said openings.
