U N l T E D S T A RICHARD MURRAY, OF NEW YORK, N. Y.
CONCRETE MOLD.
Application filed May 24,
To all whom it may concern:
Be it known that I, RICHARD MURRAY, a citizen of the United States, and residing at New York, invthe county of New York and State of New York, have invented certain new and useful Improvements in Concrete Molds, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.
This invention relates to concrete molds and particularly to molds of this class designed for use in molding bricks or blocks to be mounted one upon another in the construction of a building wall and the like and further to a mold which may be used in forming a wall construction by intermittently forming predetermined portions of the wall structure by said mold, and the object of the invention is to provide a device of the class and for the purpose specified by means of which the representation of a plurality of bricks or blocks may be formed in' one molded body, and whereby apertures may be formed therein, meansbeing employed whereby a single brick section or a predetermined number of brick sections may be formed whenever desired; a further obj ect being to provide a mold of the class and for the purpose specified composed of separate detachably and adjustably connected parts with means for holding the separate parts in predetermined spaced relation; a further object being to provide the end portions of the mold with means whereby a continuous series of molded sections may be formed on a wall structure; a still further object being to provide means for holding the several parts of the mold in operative position and whereby parts thereof may be automatically separated in the operation of releasing the holding means; and with these 1 and other objects in view, the invention con sists in a device of the class and'for the purpose specified, which is simple in construction, efficient in use and which is constructed as hereinafter described and claimed.
The invention is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are. designated by suitable reference characters in each of the views, and in which:
Fig. 1 is a plan view of one form of mold which I employ, with part of the construction broken away and in section.
1924. Serial No. 715,522.
Fig. 2 is a transverse sectional view of the mold shown 1n Fig. 1 on an'enlarged scale and with part of the. construct-ion broken away.
Fig. 3 is a longitudinal sectional view through one end portion of the moldshowu in Fig. l and showing a modification.
Fig. 4 is a partial section on the line l-1 of Fig. 3.
Fig. 5 is a diagrammatic view showing another use of the mold shownin Figs. 1 and 2 of the drawing, with part of the construction omitted, the mold being shown in longitudinal section and mounted upon a wall construction partially formed by the use of said mold; and,
Fig. 6 is a section on the line 66 or Fig. 5, and on an enlarged scale.
a In the construction shown inFigs. 1 and 2 of the drawing, myimproved mold is composed of a bottom or base member 10 which may be composed of metal if desired, but in the construction shown is composed of strip of wood faced bya metal sheet 11. Side mold platemembers' 12 and 13 are employed in coni'iection with the base member 10 .and maybe composed of a suitably constructed metallic body, but in the construction shown are composed of wood strips faced on their inner faces by sheets of metal 14. The member 13 is provided with inwardly projecting ribmembers15 forming mold faces which represent on the concrete body formed by the moldor in one face thereof, bricksections as diagrammatically illustrated in Fig. 50f the drawing.
Pivotally mounted in connection with the top face of the member 12 substantially cen trally thereof is a gage bar 16 having spaced apertures 17 at its free endportion which are adapted to operate in connection with a. headed lock member 18 in connectionwith and 2. The gagebar l6 operates'to hold the upper end portions of the members 12 ing the members 12 and 13 inwardly to re the member 13 as clearly shown in Figs. 1
tain the same in proper position. One jaw,
the stationary jaw 20 of the clamp 19, is
adapted to seat in a keeper 21 secured to the outer face of the member 12, while the adjustable and movable jaw 22 of the clamp.
engages a similar keeper 23 on the outer face of the member 13. \Vith this construction,
by releasing the jaw 22, the members 12 and signedto form an aperture in one end of a 13 will be automatically separated to free themselves from the molded body of concrete or similar material. On inner adjacent faces of the end-portions of the members 12 and 13 are U-shaped guide members 24 to receive and support end walls or gates 25 and 26 which form a finish to the ends of the body to be formed in the mold, but these end walls or gates may be spaced intermediate the two shown in Fig, 1 of the drawing in the manner shown in Figs. 3 and l of the drawing wherein a gate or wall 27 is shown, whereby a single brick size body may be formed or a body of any. number of brick size formed, as may be desired.
At the end portion of the mold, provided with the gate 25 as shown in Fig. 1, is employed a transverse bar 28 which is secured to the top face of the member 13 and passes through a keeper 29 secured to the top face of the member .13, while the other end portion of the'mold is provided with a bar 30 secured to the outer end of the member 12 adjacent to the lower end portion thereof and the bottom edge of which is in line with the top face of the bottom member or base 10 of the mold, and the bar 30 passes through a. keeper 31 secured to the member 13 and positioned thereon to retain the bar in the position above set out.
I also employ a core member 00 in the form of an elongated bar 34 having on its lower face a plurality of depending and equally spaced core pieces 85 adapted to form apertures in the bodies formed by the mold, and as shown in Figs. 1 and 2 of the drawing the core pieces 85 rest upon the base 10, and the core member 30 is retained in proper position by transverse bars 36 positioned adjacent the end portions thereof and which cooperate with keepers37 mounted upon the members 12 and 13.
The mold shown in Figs. 1 and 2 of the drawing is designed primarily for use in forming elongated blocks or sections of concrete, which when formed represent a plurality of brick or block sections formed in one unitary body, it being understood that the concrete is inserted into the mold, when the parts thereof are assembled, through the spaces which open outwardly through the top thereof and when theconcrete section has been formed and set sufficiently, the gage bar ismoved into inoperative position, the clamp operating to separate the members and 13, 'and the concrete member removed, it being understood that the rods 28 and 30 perform no functionin the formation of concrete block sections, as above set out. It
will also be understood that the clamp 19 is removable from the keepers 21 and 23.
In the construction shown in Figs. 3 and 4, the gate or wall 2-7 is provided with a longitudinally directed core piece 27 debrick or block formed within the space between the gate or wall 25 and the gate or wall 27.
In addition to using my improved mold for forming separate brick or block sections as above set out, the same may be used in the construction of a wall or other concrete structure, in which event, the bottom or base member 10 of the mold is not employed; and in this use of the mold, the members 12 and 13 form side mold faces, which rest and bear upon the inner and outer faces of a previously formed wall or concrete structure, which however has been formed by the said mold, and in Fig. 5 of the drawing, the wall or concrete structure is shown at 38. Inworking from left to right, the mold as shown in the drawing is employed, and the bar 28 rests upon the top of a previously formed portion of the wall as indicated at the left of Fig. 5 of the drawing, while the bar'30 rests upon the top of the wall upon which the new section is to be formed as shown at the right of Fig. 5 of the drawing, it being understood that said rods retain the mold in proper position or longitudinal alinement. The clamp 29 is used for compressing the members 12 and 13 and holding the same in firm engagement with the wall structure 38 in the same manner as the engagement of said members with the base member 10 in the first named use of the mold, and the gage bar 16 serves tohold the top portions of the members 12 and 13 in proper spaced relation. lVith the use ofthe mold as shown in Figs. 5 and 6 of the drawing, the core pieces 35 extend downwardly into the apertures 3 8? previously formed in the wall structure, as clearly illustrated in Fig. 5 .ofthe drawing, whereby continuous passages are formed through the wall structure 38.
After the mold has been mounted in proper position as indicated in Figs. 5 and 6 of the drawing, the concrete is poured thereinto, and allowed to set sufficiently to permit of the removal of the mold parts, which will be a comparatively short time, es
pecially when quick setting cement or con crete is employed, and the mold may be removed and shifted to form another wall section. It will also be apparent that in the above operation or use of the mold shown in Fig. 5 of the drawing, the end wall 25 as well as the guide members 2% are removed at the left hand end portion of the mold and the wall 26 only is employed. In working from right to left however or in the reverse direction, a mold will be employed in which the rod 28 is at the right of the mold and the rod 30 at the left of the mold and the end wall 26 will be removed together with the guide members therefor. In other words, the mold will be made up in lefts and rights, building wall or other concrete body structure, it will be apparent that any desired number of the molds may be employed, and the molds may be modified to form curvatures in the wall or concrete body structure as well as corner formations, the distinctive novelty of my invention residing in the provision of a portable mold device which may be quickly mounted in position, and shifted into new positions in the formation of a wall.
In the last named use of the mold, it will be understood that the inwardly projecting rib members cooperate with the grooves previously formed by said rib members in forming predetermined sections of a wall; and in Fig. 6 of the drawing, I have shown one of the 'rib members engaging the top recess of the wall structure 38.
It will be understood that while I have shown certain details construction for carrying my invention into effect and especially in the formation of the mold parts proper and the means for operating the same, and for retaining the same in spaced relation, I am not necessarily limited to the details of construction here-in shown and described, and various changes therein and modifications thereof, may be made within the scope of the appended claims without departing from the spirit of my invention Cir or sacrificing its advantages.
