UNITED STATES PATENT OFFICE.
NEWTON F. ATWOOD, OF JOHNSTON CITY, ILLINOIS.
CONCRETE-IBLOCK-FORMING MACHINE.
Application filed September 19, 1919. Serial No. 324,829.
To all whom 2 2, may concern Be it known thatl, N nwroiv l Arwoon, a citizen of the United States, residing at Johnston City, in the county of Williamson. State of Illinois,,have invented a new and useful Concrete Block Forming Machine; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. i
The invention relates to concrete block forming machines and has for its object to provide a machine of this character wherein a frame is provided having a pivoted lever pivoted therein, saidlever being provided with cores adapted to be moved downwardly in an are so that said cores will enter a plastic material disposed in a collapsible form carried by one end of the frame. Also to provide means whereby the forms may be placed on the frame quickly without the necessity of gaging the form relative to the lever-carried cores.
A further object is to provide the frame with a transversely disposed bumper for limiting the downward movement of the free end of the lever and to provide means whereby the lever when raised beyond a certain point will be supported in raised position by a member pivotedtothe side of the frame.
A further object is to provide a form box comprising a bottom and a permanently fixed back, said bottom having pivoted thereto at its forward edge an upstanding front,
the back having pivoted thereto end pieces,
the forward ends of which are provided with lugs adapted to be received by apertures in the pivoted front piece. The box as a whole being maintained in open position by hooks carried by the end pieces and engaging eyes in the front piece.
With the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawings, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.
In the drawings z Figure 1 is a longitudinal sectional view through the block forming machine.
Fig. 2 is a sectional view taken on line 2-2 of Fig. 1.
Fig. 3 is a horizontal sectional view taken on line 3-3 of 1.
Fig. 4t is a front elevation of the form box.
F 1g. 6 is a perspective view of a portion of the form box.
Fig. 7 is a detail perspective view of the interengaging means between the end pieces and the front piece of the form box.
Fig.8 is a detailview of the core end of the pivoted lever.
Fig. 9 is a detail view of the core end of the pivoted lever showin different shaped cores from that shown in *ig. 8.
Fig. 10 is a. detail view showing the lever supporting means.
Referring to the drawings, the numeral 1 designates a frame which comprises the side members 2 which are held in spaced relation to each other by cross bars 3 and 4:- Pivoted in the frame 1 on a transversely disposed rod 5 is a U-shaped lever 6. y The forward end of the U-shaped lever 6 is provided with a handle member 7 adapted to be grasped by the operator during a block forming operation so that said lever may be forceddownwardly and the cores 8 which are carried by a plate 9 secured in any suitable manner to. the lever 6 may be forced and embedded in the plastic material in the form box 10. Cores 8 may be of various shapes and numhers so that if so desired it will be possible to form blocks of different shapes and ornamentation, which is particularly desirable in bricks and other plastic building materials. In Fig. 9 a series of cores 11 are shown which are particularly adapted for forming ornamentation on bricks and blocks.
The bottom rails 12 of the side frames 52 extend forwardly beyond the end of the frame as a whole thereby formin supporting means for the form box 10. ecured to the inner faces of the forwardly extending portions 13 of the rails 12 are L-shaped adjusting members 14 having one of their arms 15 extending upwardly above the upper surfaces of the portions 13 and forming abutment against which the form box 15 is adapted to engage thereby obviating thenecessity of adjusting each form box as it is used so that the cores 9 will properly register with the plastic material within the form boxes. Arms 16 of the L-shaped members 14: are provided with elongated slots 17 through which slots set screws 18 pass so that the arms may be adjusted inwardly and outwardly according to the size and shape of form boxes that are being used.
The plastic block having been formed lever 6 is raised until it assumes substantially the position shown in Fig. 1 in dotted lines, then a. pivoted arm 19 is moved inwardly on its pivotal point 20 so that its upper end 21 will engage under the side rail of the pivoted lever 6, thereby maintaining the lever in raised position. Normally lever 19 is held at an angular position by its cutaway portion 22 engaging the upper surface of the side 2 thereby allowing the lever 6 to pass between the side members 2 of the frame.
It is to be understood that a series of form boxes is to be used, and that as oneform box is used and the plastic block formed that the box is to be removed and another box placed in position on the members 13. Each form box comprises a bottom 23, which bottom has secured thereto a permanently fixed back 24. Hinged as at 25 to the forward edge of the bottom 23 is a front member 26. Sides 27 are provided, which sides are hingedly'connected to the ends of the back 24: as at 28 and are adapted to swing inwardly toward each other in a horizontal plane. The forward ends 29 of the sides 27 are provided with lugs 30 adapted to be received by apertures 31 in the ends of the front member 26, thereby locking the ends 27 against inward or outward movement. T he front member 26 is held in engagement with the ends of the sides 27 by means of hooks 32 which are pivotally secured as at 33 to the side members 27 and have their hooked ends 34: engaging eyes 25 in the ends of the front member 26. It will be seen that the sides and front member will be securelv locked together and when it is necessary to collapse the forms for removing the blocks therefrom it will only be necessary to raise hooks 32 out of engagement with the eyes then pull the front 26 forwardly after which the sides 27 may be pivoted outwardly in a horizontal plane thereby allowing the removal of the formed block. I
From the above it will be seen that a concrete block forming machine and box is provided which may be quickly and easily handled and one wherein the blocks after being formed may be quickly removed from the forms.
The invention having been set forth what is claimed as new and useful is 2- A concrete forming machine comprising a frame, said frame having pivoted in the rear end thereof a lever, the free end of said lever being provided with a series of cores, the forward end of the frame being provided with forwardly extending formsupporting members, L-shaped brackets carried on the inner faces of the form supporting members and means whereby sa1d L-shaped brackets may be adjusted inwardly and outwardly so that form boxes of a uniform size may be adjusted so that the cores carried by the free end of the pivoted lever will register with the form boxes as said lever is pulled downwardly.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
