BRICK-MACHINE.

Specification of Letters Patent.

Patented Dec. 13, 1910.

Application filed June 27, 1910. Serial No. 569,187.

To all whom it may concern:

Be it known that I, HERMAN IV. LAMP- MAN, a citizen of the United States, residing at Lagrange, in the county of Lagrange and State of Indiana, have invented a new and useful Brick-Machine, of which the following is a specification.

This invention relates to hand brick machines of the type forming the subject matter of U. S. Letters Patent No. 847,613, dated March 19, 1907, and issued on the application of F. WV. Steinhofi'.

The object of the present invention is to improve, simplify and strengthen the construction of device set forth in said patent, as well as to render it easier to manufacture and use; furthermore, to increase its durability and to decrease the expense attending its manufacture.

WVith the foregoing and other objects in View which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of the claims without departing from the spirit of the invention.

In the accompanying drawings forming part of this specification, Figure 1 is a longitudinal vertical section through a brick machine constructed in accordance with the present invention, the machine being shown in position upon a work bench adapted for convenient use therewith. Fig. 2 is a transverse vertical section through the brick machine. Fig. 3 is a side elevation, partly broken away and in section, showing the brick machine after it has been inverted and the back plate forced down toward the compartment mold box so as to discharge the molded articles therefrom. Fig. 4 is a detail view of a slight modification in the core. Fig. 5 is a sectional View taken at a right angle to Fig. 1.

Like reference numerals indicate corresponding parts in the different figures of the drawings.

The brick machine of the present invention preferably, although not essentially, is used in connection with a work bench or support consisting of the end pieces or legs 1-1 and the top piece 2, said top piece being formed in one edge thereof with a cut away portion or slot 3 into which the brick machine of the present invention can be fitted during the operation of supplying the material which is to be molded.

The brick machine proper consists of a compartment mold box which is formed preferably of sheet metal and includes the parallel side plates 4-4. Mounted between the side plates l are the cross plates 5. Each of the cross plates 5 is formed at each of the ends thereof with a plurality of extensions or lugs (S6, each of said lugs being extended through a short vertical slot 7 in the adjacent side plate and upset or otherwise secured therein. By providing the side plates 1 with a plurality of short slots 7 to receive the extensions (5, the strength of the mold machine is materially increased. The cross plates serve to separate the mold box into a plurality of mold compartments 8, 9 and 10, three of such compartments being shown in the drawings, although it is to be understood that this number may be increased or decreased at will. Extending transversely across the lower ends of each of the mold compartments 8, 9 and 10 are two cross rods 1111 said cross rods being preferably disposed adjacent the ends of the compartments in which they are located. Normally resting upon each pair of cross rods 11 in each of the compartments 8, 9 and 10 is a core plate 12 which forms the bottom of the mold box as shown in Fig. 1 and is held in proper position by the cross rods 11. Each of the core plates 12 preferably is provided on its upper surface with a plurality of knobs or projections 13 which preferably consist of bolt heads, and are adapted to contact with the inner walls of hollow core members 16 formed of cast metal or other suitable material. Each core member 16 is held in position in the mold compartment in which it is located by means such as the bolt 17 which extends through the upper surface of the hollow core 16 and through the core plate 12, said bolt 17 being provided on its lower end with a nut 18 and on its upper end with an enlarged head 19 which rests upon the upper surface of the hollow core. The bolts 17 serve to hold the hollow cores securely in position in the mold box and the projections or knobs 13 by engaging the inner walls of said cores, serve to prevent the hollow cores from rotating or being displaced upon the core plates 12. Extending downward from the lower surface of each of the core plates 12 at a point thereon approximately beneath the lower edge of the hollow core plate 16 is a pair of connecting plates 2020 each of said connecting plates having its upper end bent into the form of a flange 21 lying on the lower surface of the core plate 12 and being bolted or otherwise secured thereto by means of the bolts 13. Each of the connecting plates 20 is formed at its lower end with a laterally extending flange 23, the flanges 23 of each pair of connecting plates 20 being directed toward each other and being bolted or otherwise connected as indicated at 24 with a back plate 25 which extends in parallelism with the three core plates 12. The longitudinal or side edges of the back plate 25 preferably are formed with upstanding integral flanges 27 which are slightly separated from the outer edges of the connecting plates 20 and the flanges thereof as shown in Fig. 2.

For the purpose of facilitating the handling and unloading of the brick machine, the side plates l of the compartment mold box preferably are extended beyond the end cross plates 5-5 as indicated at 30. Mounted between the parallel extensions 30 are the cross rods 31 on which are mounted the sleeves 32 which serve as handles for use in manipulating the machine.

In operation, the machine preferably'is placed upon the work bench or stand in the position illustrated in Fig. 1 and the cement or other material is poured into the mold compartments 8, 9 and 10 and is troweled off, tamped or otherwise treated. After the material has set snfliciently, the brick machine is removed from the work bench by means of handles 32 and is inverted as indi cated in Fig. 8, after which the back plate 25 is forced downward toward the compartment mold box with the result that the core plates 12 eject the molded articles from the V compartment mold.

In the modified construction shown in Figs. 4 and 5, the core members 16 are slightly thickened as indicated at 35 at the portions thereof which are in engagement with the bolts 13'.

The device of the present invention is I strong, simple, durable and inexpensive in construction as well as thoroughly practical and eflicient in use.

Vhat is claimed as new is:

1. A brick machine including a compartment mold box made up of side plates and cross plates, the ends of the side plates being extended beyond the end cross plates and having handles mounted therebetween, cross rods in each of the compartments of the mold box, core plates mounted on said cross rods and having knobs projecting upward therefrom, hollow cores in engagement with said knobs at opposite portions and held against movement thereby, a bolt extending through each of said cores and through the core plate, a back plate, and connecting plates mounted between the core plates and said back plates.

2. A brick machine comprising a compartment mold box consisting of side plates having slots therein, a plurality of cross plates each having a plurality of lugs on each end thereof extending through the slots of the side plates and riveted therein, the ends of the side plates being extended beyond the end cross plates, handles mounted between the extended ends of the side plates, a plurality of cross rods extending across the lower ends of each compartment of the mold box, a core plate mounted in each compartment and resting normally on the cross rods, each core plate having a plurality of headed bolts, a hollow core in engagement with said headed bolts and held against movement thereby, a bolt securing each core to its core plate, a back plate having longitudinal flanges, and a pair of connecting plates mounted between each core plate and the back plate, each connecting plate having an upper flange secured to the core plate by said headed bolts, and a lower flange secured to the back plate between the longitudinal flanges thereof.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
