PETER WEGHT AND JOHN WINFIELD, OF FOSTORIA, OHIO.

MACHINE FOR MAKING CONCRETE BLOCKS.

Specification of Letters Patent.

Patented March 16, 1909.

Application filed January 24, 1908. Serial No. 412,506.

To all whom it may concern:

Be it known that we, PETER WEoHr and JOHN WINFIELD, citizens of the United States, residing at F ostoria, in the county of Seneca and State of Ohio, have invented new and useful Improvements in Machines for Making Concrete Blocks, of which the following is a specification.

This invention relates to machines for making concrete blocks. k

We desire to indicate that we use the terms concrete and block intheir broad meanings. By concrete the substance not only thus specifically known, but equivalent substances or compositions, such as cement, for making blocks of whatever form the latter may be.

We may make window sills, window caps, steps, building blocks, and other articles by the apparatus. acter that blocks of different sizes can be made thereby, and these operations can be accomplished with ease and rapidity.

The apparatus is simple in construction and capable of ready manipulation.

In the drawings accompanying and forming part of this specification we have" shown in detail one advantageous form of embodiment of the invention which, to enable those skilled in the art to practice said invention, will be set forth in detail in the following description, while the novelty of the invention will be included in the claims succeeding said description.

eferring tosaid drawings: Figure 1 is a perspective View of the machine with the mold-box set up. Fig. 2 is a cross sectional view of the upper portion of the machine with the m0ldbox in knock-down condition. Fig. 3 is a top plan view of the machine with %he parts occupying the position shown in 1g. 1. view of the same, the boX being also set up. Fig. 5 is a pers ective view of arock-shaft, actuating hand e, latches, and certain cooperating devices hereinafter more particularly described. Fig. 6 is a perspective view of an end and a supporting cross-bar therefor. Fig. 7 is a like, view of a compound core, the parts thereof being separated. Fig. 8 is a top plan view of a modified form of core.

Like characters refer to like parts throughout the several figures of the drawings.

We prefer to provide a supporting frame for the mold-box and, while said supporting we intend to include he latter is of such char-' Fig. 4 is a longitudinal sectional frame may be of any desirable character, such a one as that illustrated particularly in Figs. 1 to {i of the drawings is advantageous. This supporting frame involves in its makeup a skeleton top represented as consisting of the longitudinally-extending parallel side bars 2 and 3 and the end bars 4 and 5 joined together in any desirable way so as to form a substantially skeleton or open structure. The structure just set forth is indicated as provided with several depending legs each designated by thenumeral 6 and WlilCh'GOllstitute a convenient means for upholding said top or skeleton structure. The sidebars 2 and 3 constitute in the present case supporting means for the cross-bars 7 and'8 which are connected by bolts or in any other suitable manner with said side-bars.

The bolts connecting the cross-bar 7 with the side-bars 2 and 3 are designated by 9, and the crossbar 8 is connected 'to'the s de bars 2 and 3 by bolts 10, the latter extending through longitudinally-disposed slots as 11 in the said side-bars 2 and 3, by virtue of which the cross-bar 8 can bemoved toward and from the companion cross-bar7 and longitudinally of the sidebars 2 and 3 for the purpose of adjustment. The bolts 9 and 10 are equipped with the customary nuts and, prior to adjusting the cross-bar 8, the nuts of the bolts 10 are loosened, when the ad ustment can be easily accomplished and, when obtained, the nuts for said bolts will be set up. To aid the nuts 0f the bolts 10 in retaining the adjustment of the cross-bar 8 we prefer to roughen the engaging faces of the cross-bar 8 and the side. or longitudinallyextending bars 2 and 3, and this we may accomplish by providing teeth, designated by 12 in each instance, on said engaging faces.

To the cross-bar 7 is hinged a mold-box end 13, while to the cross-bar 8 is hinged a substantially similar mold-box end 14. By virtue of the hinge connection the two ends can be separated from their cooperating cross-bars. The bottom 15 of the mold-box is removably supported by the two cross-bars 7 and 8 and, when in operative position as shown in Fig. 4, is inclosedby the lower portions of the two ends 13 and'14 and the sides 16 and 17. The side 1 6 is represented as hinged to a longitudinally-extending bar as 18 illustrated as sustained at its opposite ends by the cross-bars igand 5. By virtue of the hinge connection of the side It? with the bar 18 the two can be separated. The bar 18 eXtends through longitudinall -disposed slots denoted in each case by 19 in the crossbars 7 and 8, as shown clearly in Fig. 1. This longitudinally-extending bar 18 is capable of adjustment transversely of the top of the frame. It may be fastened to the crossbars 4 and 5 by bolts as 20 shown as extending through longitudinally disposed slots as 21 formed in said cross-bars 4 and 5. By tightening up the nuts of the bolts 20 the longitudinally-extending bar 18 can be maintained in an adjusted position and the bolts 20 may be aided in maintaining this relation by cooperating teeth as 22 formed respectively on the cross-bars 4 and 5 and bar 18.

The cross-bars 4 and 5 are represented as provided with bearings,designated by 23 in each case, to removably receive the opposite ends of a rock-shaft as 24 extending freely through openings or perforations in the cross-bars 7 and 8, by virtue of which the bar 8 can be freely adjusted with respect to said rockshaft, whereby the latter can be operated without affecting the said bars 7 and 8.

To the rock-shaft 24 are fastened in some suitable manner the two outwardly-extending arms 25 which, when the mold-box composed of the several parts hereinbefore de scribed is in its operative relation or assem bled, stand vertically, as indicated in Fig. 1. In addition to said vertically-disposed arms 25, the rock-shaft 24 has fastened thereto horizontally-extending arms as 26 to which the mold bottom 15 may be removably fastened. The mold-bottom is shown as equipped on its under side with ribs as 27 adapted for removable connection, for eX-' ample, by means of bolts as 28, with the arms 26, such bolts preferably passing through longitudinal slots in the ribs 27 and arms 26, respectively, so as to adapt said arms 27 to mold-bottoms of varying widths. The two arms 25 are shown as connected by a bar as 29 upon which the mold-side 17 is adapted to rest, as clearly shown in Fig. 1.

It will be assumed that a mold-box of the size such as that shown in Fig. 1 is being used and that the box is knocked down or collapsed, as shown in Fig. 2, preparatory to using a box which is longer and wider than that illustrated. To use such a box the ends 13 and 14, the sides 16 and 17 and the bot tom 15 will be dismounted, after which the cross-bar 8 will be moved away from the companion cross-bar 7 in the manner previously set forth; following this the longitudinallyeextending bar 18 will be moved away from the shaft 24; or the order of procedure just outlined may be varied as it is quite clear that we provide means for effecting the variation in size of the mold-box. We may readily increase the length thereof without affecting the width, or the width can be changed without affecting the length,

or both dimensions can be altered in a ready quick manner.

The side 16 is represented as provided near its top with a longitudinally-extending cleat as 30 the ends of which project beyond the ends of said side 16 for engagement by gravity latches as 31 connected with the rockshaft or pivot 32 for swinging movement, the engaging portions of the latches 31 and pro jecting ends of the cleat 30 being notched. When the latches 31 are in engagement with the'projecting portions of the cleat 30 the mold-box consistin of the bottom, two sides, and ends will be he d in operative condition.

It will be assumed that the mold-box is set up as shown in Figs. 1, 3, and 4. In this condition the bottom 15 is connected with the rock-arms 26 then horizontally-disposed and is inclosed by the lower portions of the ends 13 and 14 and the sides 16 and 17, the side 17 resting on the supporting member 29. When the box is in such condition it can be filled with cement or concrete up to the desired level and, when the mass in the box has set or partially set, the latches 31 will be lifted. The side 16 can then be dropped down, after which the same operation will be followed with respect to the ends 13 and 14. Following this the shaft 24 will be rocked to bring the side 17 to a horizontal position, and the bottom 15 to a vertical position. The side 17 can then be removed from the arms 25 and the molded block will go with it. A new side can be substituted for that removed, or the block can be removed from the side when the former has set. The shaft 24 is provided with some suitable means for effecting its operation by hand, and a lever as 33 may be provided for this purpose.

We may, if desired, in forming a hollow block employ a core such as that shown in Fig. 7 said core consisting of a body or main portion as 34 and an auxiliary portion as 35 both represented as cylindrical although their particular shape is not material. The end 14 is shown as having a circular hole 36 through which the main core section 34 can be passed from outside the mold-box, the operation continuing until the forward end of the core portion 34 abuts against the mold end 13. The core ortion 34 may be provided with a hand e as 37 to facilitate its operation and it is also represented as having a circular opening 38 entirely through the same to receive the transversely-disposed auxiliary core portion 35 which, it will be understood, is of less diameter than the main core portion. The side 16 has a circular opening as '39 to receive the auxiliary mold portion 35 which is put in place after the main portion is positioned, by passing said auXilary portion 35 through the opening 39 and then through the opening 38 until the inner or forward end of said mold ortion 35 abuts against the side 17, at whicfi time the mold-box can be filled with cement. mold portion 35 is provided with a handle as 40 to facilitate its operation. I

We have shown as pivoted to the ends 13 and 14 core blocks designated by 41 in each case and which are arranged to hug closely the main core portion 35 near opposite ends j thereof and which form in the ends of the I block cavities. i

l-Ve show a modified form of core in Fig. 8 consisting of a main portion and an auxiliary portion 35 The core shown in Fig. 7, when the parts thereof are connected, is of approximately cruciform shape. The modilied form of core illustrated in Fig. 8, however, is approximately of L-form. The core portion 35 removably ts the core portion 34 just as is the case with the other form of core.

The various parts hereinbefore described may be made of wood, metal, or a coinbination of these materials, as deemed desirable or to meet particular conditions.

It will be apparent from the foregoing description that we provide for the adjustability of a moldbox. To adapt the latches 31 to the particular size of the mold-box we prefer that said latches be adjustable of the shaft 32. This can be accomplished by having the latches slide on the said shaft and in retaining them in their respective adjusted positions by means of pairs of collars as 31 l/Ve have fully described that form of embodiment of the invention which we have selected for illustration in the drawings accompanying this specification and have also set forth two different forms of cores. If desired, we may use the mold-box without any core or we may employ a core entirely different from either of the two shown. In like manner the lugs or blocks 41 may be of any I desirable form or shape. I11 some cases they I may, if desired, be wholly omitted. If del sired also we can open and shut the moldbox with a lever or lever mechanism.

Other details may, if desired, be adopted within the scope of our claims.
