Specification of Letters Patent.
Patented Oct. 11, 1910.
Application filed December 6, 1909. Serial No. 531,620.
To all whom it may concern:
Be it known that I, ANTHONY I-IAAG, a citizen of the United States, residing at Bronx, in the county of New York and State of New York, have invented certain new and useful Improvements in Plumbing Apparatus for Concrete-Wall Molds; and I do 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.
This invention relates to improvements in plumbing and adjusting apparatus for concrete wall molds.
The object of the invention is to provide an apparatus by means of which the molds or forms for concrete walls are adjusted and firmly held in position while being filled with concrete and which may be employed in the construction of either hollow or solid walls.
lVith the foregoing and other objects in View, the invention consists of certain novel features of construction, combination and arrangement of parts, as will be more fully described and particularly pointed out in the appended claims.
In the accompanying drawings: Figure 1 is a vertical sectional view of the lower tier of forms showing the arrangement of my adjusting apparatus before the concrete is applied to the forms. Fig. 2, is a similar view after the concrete has been applied to the lower tier of forms and the upper tier of forms arranged thereon to receive the second course of concrete. Fig. 3, is a detail perspective view of one of the plumbing standards. Fig. 4 is a similar view of one of the form holding and separating bars for maintaining the forms in place while being filled. Fig. 5 is a similar View of the plumbing and separating bar for the tiers of forms above the first tier. Fig. 6 is a similar view of one of the metal ties for holding the sections of the wall together after being formed and which also serve to hold the lower end of the plumbing standard and to separate the same while in use. Fig. 7 is a plan View of one of the washers used in connection with the tie. Fig. 8 is a detail perspective view of one of the plates for holding the ends of the forms together.
In the embodiment of the invention, I provide a suitable number of forms which are preferably in the form of steel plates 1, of suitable size and thickness, which are arranged at suitable distances apart to form a wall of the desired thickness. WVhen a solid wall is to be formed, I employ simply an inner and outer series of plates 1 and when a hollow wall is to be formed, additional plates are used and are arranged a suitable distance apart between the outer plates to form a space of the desired width between the two sections of the wall.
In forming the wall, strips 2, of wood, of suitable size are laid along on top of the concrete footing or base 3, of the wall at the proper distance apart after which tie bars 4, hereinafter more particularly described, are laid upon the footing between the strips 2. The outer forms or plates of the lower tier are then set up on the concrete footing and tie bars and against the inner edges of the strips 2, as shown. When a hollow wall is to be formed, inner plates or forms 1 are set up on the footing and tie bars at suitable distances apart and spaced from the outer plates the required distances for forming the inner and outer sections of the wall.
The tie bars 4, are in the form of strips of metal of suitable width and thickness and of sul'licient length to reach across the width of the wall to project beyond the outer sides of the same. in the projecting ends of the bars a, are formed square holes 5, in the outer edges of which are formed notches 5, the purpose of which will be hereinafter described. ln the bars, at a suitable distance from each side of the center thereof, are outwardly projecting pairs of parallel ears or lugs 5 which are preferably formed by cutting semi circular slits in the bars and bending the cut metal upwardly, as clearly shown in Fig. 6, of the drawing. When the forms 1, are set up for use, the lower edges of the inner forms are engaged with and held in position by the parallel ears 5, of the tie bars.
The outer plates or forms of one side of the mold are held or supported in an upright position by means of plumbing standards 6, the lower ends of which are reduced and are engaged with the notches 5 in one end of the tie bars at. The upper portions of the plate or form on the opposite side of the mold and the intermediate plates or forms are supported and held in spaced relation with each other by means of spacing bars 7. The bars 7, are preferably T- shaped in cross section-and in the lower portion of the same are formed a series of notches 8, which are engaged with the upper edges of the plates or forms 1, and thereby holding the same in adjusted positions. In 1 the opposite sides of one end of the bar 7,
is formed a series of notches 9, which are adapted to be engaged wlth the plumbing standards 6, adjacent to the upper edges of the plates, thereby holding the plumbing standards in close engagement with the ad- 3 In addition to the separating bars arranged opposite each of 5 the plumbing standards, I may also employ any suitable number of intermediate spacing bars arranged in between the bars which engage the standards. The plates or forms are preferably secured together by small metal plates 1 having punched from and formed thereon hooks 1 which are engaged with suitable holes formed along the adjoining edges of the plates. The lower ends 1 of the standards 6, when forming the first course of concrete, are preferably secured to the wooden strips 2, by staples or other suitable fastening devices.
After the concrete has been applied to the lower forms of the molds and has sufficiently set or hardened, the inner forms or plates and the spacing bars 7, between the standards 6, are removed. After these parts have been removed, the spacing bars, opposite each of the plumbing standards, are retie bars a, constructed as hereinbefore described. In applying the tie bars, one of the apertured ends thereof is slipped over the upper end of the plumbing standard and said bar is then brought down onto the upper edges of the outer plates or forms and onto the first course of concrete. After the bars have thus been brought down, the notch 5 of the hole 5, which is applied with 1 the standard, is engaged with a notch 11, formed in the outer edge of the standard, adjacent to the upper edge of the side plate or form, thus providing an interlocking connection between this end of the tie bar and the plumbing standard. After the tie bar has thus been engaged with the standard, a flat washer 12, which is preferably of rectangular form, is slipped to the opposite end of the bar and is forced up into engage ment with the outer side of the adjacent outer form or plate 1, of the mold by a linch pin 13, said pin having a reduced lower end which is inserted in the notch 5 of the hole 5, at this end of the bar. When the tie bars have thus been arranged, the plates or forms 1, for the second course of concrete, are set up on the tie bars. The outer plates or forms are in line with the outer plates of the lower course of concrete, while the inner plates or forms set into or between the ears 5 of the tie bars and the lower portions of the same are thereby held in proper position to form a space immediately above the space of the lower course. The outer side plates of the side of the mold, adjacent to the plumbing standards are held at their lower edges by the upper end of the vertical portion of said standards while the lower edges of the outer plates or forms of the oppo site side of the mold are held in position by the washers 12, on the tie bars lVhen the plates or forms of the second tier have been thus arranged, the upper portions thereof are adjusted and spaced the proper distance apart and plumbed perpendicular or held at any suitable angle by plumbing and spacing or separating bars 1 1, which consist of flat strips in one edge of which are formed a series of notches 15, which correspond with the notches formed in the spacing bars '7. One end of the plumbing and spacing bars 1 1, is extended and projects a suitable distance beyond the side plate or form adjacent to the plumbing standards and in said extended end is formed a slot 16, with which is engaged a clamping bolt 17, inserted through a bolt hole 18, in the end of an angular or inclined extension 19, formed on the upper end of the vertical portion of the plumbing standards 6, as shown. On the end of the bolt 17, is screwed a thumb nut 20, which is adapted to be screwed up into tight engagement with the extended end of the spacing moved and 1n place thereof, are arranged l and plumbing bar 14, after the latter has been adjusted to bring the plates or forms of the mold in proper position. In addition to the spacing or plumbing bars let, I may also, if necessary, employ any number of the spacing bars 7, in between the bars 1 1, to hold the upper edges of the second tier of forms in position and prevent the bulging of the same while being filled with concrete. After the second course of concrete has thus been laid, the inner forms and the spacing bars are removed, as hereinbefore described, and the plumbing standards are also disengaged from the lower tie bars and are moved upwardly and have their reduced lower ends engaged with the notches and apertures in the projecting end of the next row of tie bars, whereby said plumbing standards are supported and held in position in the same manner as described in connection with the forming of the first two courses of concrete. After the plumbing standards have thus been moved upwardly, the outer forms or plates of the finished lower courses of the wall are removed and the projecting ends of the tie bars are cut cit. By successively repeating the operation hereinbefore described, walls of any desired height may be quickly and easily constructed.
It will be noted by reference to Fig. 1 of the drawings that when the first course of the wall is constructed, the plates or forms 1 are braced and held in position by plumbing and separating bars 14, said bars being swung downwardly on the bolt 17 until their opposite ends are in engagement with the spacing bars 7 to the ends of which the separating bars 14 are secured by wiring as shown or by any other suitable connection. This arrangement of the plumbing and separating bars 1 1 applies only to the first round or course of forms, said plumbing or separating bars being engaged with the upper edges of the forms or plates above the first round or course, as shown in Fig. 2 of the drawings.
From the foregoing description taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.
Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention, as defined in the appended claims.
Having thus described my invention, what I claim is 1. In an apparatus of the character described, a plurality of mold plates or forms, a spacing bar, said bar having formed therein a series of vertical and horizontal disposed notches, said vertical notches being adapted to be engaged with the upper edges of the plates or forms, a plumbing standard adapted to be engaged with the horizontal notches in said bar, and having a diagonal offset end, a notched spacing and plumbing bar adapted to be engaged with the upper edges of the upper tiers of plates or forms, and means whereby one end of said bar is adjustably secured to the offset end of said plumbing standard, whereby the upper tiers of plates are held in perpendicular position or at any desired angle.
2. In an apparatus of the character described, a plurality of mold plates or forms,
footing strips adapted to be engaged by the lower edges of said plates, spacing bars adapted to hold said plates in proper position, a series of tie bars having apertured outer ends and adapted to be engaged with the upper edges of one tier of mold plates, means on said bars to hold the lower edges of the next adjacent tier of mold plates, a series of plumbing standards having vertical lower portions and obliquely disposed upper portions, said vertical portions being engaged and held in position by the apertured portions of one end of said tie bars, spacing and plumbing bars having formed therein a series of notches to engage and hold the upper edges of the upper series of mold plates in position, a slotted extension formed on one end of said spacing and plumbing bar, a clamping nut arranged in the obliquely disposed upper end of said plumbing standard and engaged with the notch in the extension of said plumbing bar, and a thumb screw on said bolt to hold said plumbing bar in its adjusted position to support the upper series of mold plates in a perpendicular position or at any desired angle.
3. In an apparatus of the character de scribed, a plurality of mold plates or forms, a series of spacing bars, said bars being T- shaped in cross-section and having formed in their side edges a series of horizontal notches, a cross bar or head arranged on one end of said spacing bars, whereby when the vertical notched portion of the bars is engaged with the upper edges in said mold plates, said cross-head will engage the upper edge of the outer plates of one side of the mold, and thereby hold said plates against bulging While the forms are being filled with concrete, plumbing standards each having a diagonal offset end and adapted to be engaged with the horizontally notched portions of the opposite ends of said bars, and a series of notched plumbing and spacing bars adapted to coact with the offset end of said plumbing standards to hold the upper edges of the upper series of plates or forms in perpendicular position or at any desired. angle.
In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
