CONCRETE-CONSTRUCTING MACHINE.

.To a/U whom, it may concern.'

Be it known that I, ALBERT A. PAULY, a citizen of the United States of America, residing at Youngstown in the` county of Mahoning and State of Ohio, have invented certain new and useful Improvements in Concrete-Constructing Machines, of which the following is a s ecication, reference being had therein to t e accompanying drawings.

This invention relates to certain new and useful improvements in concrete-constructing machines; and the primary object of this invention is to rovide a portable machine that can be easi y and quickly manipulated to construct a concrete wall, foundation, pier, abutment, or the like.

Another object of this invention is to rovide a machine of the above type that wi l be strong and durable, com aratively inexpensive to manufactui e, andp highly efficient for the pur oses for which it is intended.

Brie y described, my im roved machine comprises a base u on W ich is slidably mounted an an lar ame, and in said frame is journaled a p urality of shafts, over which chains pass to support retaining-boards, said boards being ern" oyed to form a mold or form for a foun ation or wall to be constructed. In connection with the machine I use other boards for retaining boards, which may be positioned at an angle to the first-named'boards, in order that an angle in the wall or foundation can be readily constructed.

The above construction, together with the details of the invention, will be hereinafter more fully described and then specifically pointed out in the claims, and, referring to the drawings accompanying this application, like numerals of reference designate corresponding parts throughout the several views, n which- Figure 1 is a side elevation of my improved machine. Fig. 2 is a plan. Fig. 3 is a rear elevation. Fig. 4 is a perspective view of one of the braces.

To put my invention into practice, I employ a base 1, the central portion of which is cut away, as indicated at 2. U on the base 1 I adjustably secure, by suitab e brackets 3 3, a substantially rectangular frame 4, carrying upon its front edge standards 5, the upper ends of which are provided with a cross-head 6, to which are connected rearwardly-extending bars7 7, said bars being fixed to the frame 4, as at 8 8, and serving to brace the Bpecication of Letters Patent.

Application led October 26, 1806. Serial No, 284,587.

standards 5. The front edge of the rectangular frame 4 is provided with two links 9 9, said links being connected to levers 10 19, carried by the ends of a pivotally-Inounted transverse shaft 11, said shaft being mounted upon the base-plate 1. By o erating the levers 10 1() the rectangularfiame, together with the standards 5 5 and their a purtenant parts, can be moved rearwardly.

e cross-head 6 is further braced by rear- Wardly-extending inclined rods 12 12, said rods being secured to the frame 4, as at 14 14. The standards are braced by tie-rods 15 15 and 16 16, which are connected to the sides of the rectangular frame, as at 17 17. Said tie-rods are provided with turn-buckles 18 18, in order that the standards 5 may be adjusted relatively to the rectangular frame 4. The bars 7 7 are provided with sleeves 19 19 and 20 20. In the sleeves 19 is journaled a shaft 21, while in the sleeves 20 is journaled a shaft 22. Said shafts are provided with crank-handles 23 23, a crankhandle being placed u on each side of the maccliiine, whereby the s afts can be easily rotate The cross-head 6 is provided with two T connections 24 24, andextending through said connections are angularly-disposed bars 25 25, said bars protruding over the front edge of the machine, as clearly illustrated in Figs. 1 and 2 of the drawings. Mounted in the outer ends of the bars 25 25 is a transverse bar 26. Connected to the shaft 21, as at 27 27, are chains 28 28, which pass over the transverse bai' 26 and support a retainingboard 29, said board being parallel with the front side of the machine.

Secured to the shaft 22, as at 30 30, are chains 31 31, said chains assing over the cross-head 6 of the standar s 5 and supporting a retainingboard 32 ad'acent to the standards 5 5, the board 32 an the board 29 being in horizontal alinement with one another and forming a trough in which concrete is to be placed to construct the wall.

In con'unction with the machine just described employ end boards 33 33, said boards being retained u on each side of the machine by telesco ic races 34 34, which are connected tot e rear face of the end boards, as at 35 35', and to the central standard 5, as clearly illustrated in Fig. 3 of the drawings. The boards 33 33 constitute inner retaining-boards, and in connection with these boards I employ outer retaining-boards IOO IIO

35, said boards being suspended upon chains 36 36, that pass over outriggers 37 37, carried by posts 38 38, located upon the base 1. The chains 36 36 can be .manipulated by hand or may be connected to one of the shafts 21 or 22 in order to elevate the outer retainingboards 35.

The boards 29 are connected with the boards 32, and the boards 35 are connected with the boards 33 by braces at the to s of the boards and bolts at the bottoms o the same, as illustrated in the drawin s, the braces being designated 29 and the bo ts 33.

We will assume that the machine is to be used to build a concrete foundation and that the proper position of the foundation has been determined. The machine is moved adjacent to the predetermined osition of the wall and the retaining-boar s 32 and 29 placed whereby they will form a trough to receive the concrete. After the concrete has been tamped in osition the retaining- boards 32 and 29 are e evated by the chains 28 and v 31 through the medium of the shafts 21 and 22. The boards are elevated to the top edge of the tamped concrete and are in position to receive concrete to form a top layer upon the iirst-laid concrete. This operation 1s continued until the foundation of a desired height is obtained. During the formation of the concrete between the retaininglates 32 and 29 the machine can be adjustedlby the levers 10 IO-that is, the framework of the machine can be moved relatively to the base of the machine, and in this manner the retaining-board 32 can be withdrawn from the formed concrete.

The inner and outer retainin - boards 35 and 33 are used in connection wit the retaining- boards 29 and 32 When an angle in a foundation is to be formed, these boards being positioned at any desired angle to the retain- - boards 29 and 32.

4 preferably'construct the machine of sec-v ployed capable of withstanding the rough usage to which the machines are subjected. Consequentlyr I have employed metallic pipes or tubing of a strong and durable nature which will form a framework that can be readily adjusted and transported at any time desired.

By referring to Fig. 1 of the drawin s it will be observed that the base-plate 1 o my improved machine is mounted upon rollers, whereby the machine can be easily and uickly moved from place to place as a founation-wall or the like structure is built.

Such changes in the construction and operation of the machine as Pre permissible by the appended claims may be resorted to Without departing from the spirit and scope of the invention.

What I claim, and desire to secure by Letters Patent, is

1. In a machine, the combination with a base-plate, of a rectan ular frame adjustably ymounted upon said p ate, standards carried by said frame, brace-rods connecting said standards and said frame, revoluble shafts carried by said brace-rods, a cross-head carried by said standards, a bar su ported by said cross-head, chains connectedpwith said shaft and extendin over said cross-head and said bar, retaining-boards supported by said chains, retaining-boards sup orted by said standards, retaining boar s adjustably mounted upon posts, substantially as described.

2. In a machine, the combination of abaseplate, standards adjustably mounted upon said base-plate, a crosshead carried by said standards, a bar su ported b said crosshead, retainin -boar s suspen ed from said cross-head an said bar, other retainingboards mounted adjacent to said base-plate, means to adjust said retaining-boards, substantially as described.

In testimony whereof I ax my signature in the presence of two witnesses.

ALBERT A. PAULY.
