' all in a single piece which may be plain or decorated, as desired.

Another object of the invention is to provide means for quickly molding concretecurbing in the form of a rectangular curb made in a single piece or'casting of any required size forprotecting graves or for other purposes.

These ,and other objects may be attained by the means of the construction illustrated in the accompanying drawings, in which F igure' 1 is a top plan view of a mold made in accordance with my invention, said view showing a curbing in the mold; Fig. 2 is a top plan view of the mold with the curb removed and the inner member or core of the mold collapsed or adjusted inwardly to permit its removal from the mold box or frame; Fig. 3 is a longitudinal section taken on the line 3 3 of Fig. 1 looking in the direction indicated by the arrow; Fig. 4 is a longitudinal sectional view taken on the line 4-4 of Fig. 1 looking in the direction indicated by the arrow; Fig. 5 is a longitudinal sectional view taken on the line of Fig. 2, looking in the direction indicated by the arrow; and Fig. 6 is a transverse vertical sectional view taken on'the line 66 of Fig. 1 looking in the direction indicated by the arrow.

Referring to the drawings, the numeral 1 designates a mold box or frame which may be of any required size depending upon the character of the curb to be molded, said frame being contracted at its upper side and flaring at its lower side as shown in the drawing.

The collapsible core for molding the curbs comprises four members 2, 3, 4 and said members having angularly bent ends which are beveled as at 6, said beveled ends adapt ed to be adjustable,-to expand and contract permitting adjustment.

the core. The members 2 and 3 are each provided with a lug 7. A pivot latch 8 is connected to a curved lever 9 near the pivot point 10 of the lever said lever being pivoted at 10 upon a lug 11- secured to the memhere 4 and 5 at opposite ends of the core upon the inside-thereof. Connected to the curved levers 9'are suitable links or bars- 12, said bars being pivoted at their meeting ends upon a bolt 13 which extends through a lever 14 provided with a circular head, the fulcrum of the lever being eccentric to the head. The lever 14 is pivoted at 15 upon a pin or rivet which passes through an elongated slot24 in the side 4 of the core. A link 16 is provided with a strap passing around the eccentrically mounted circular end of the lever 14, said link being provided with a shank 17 provided with notches 18 near the end thereof. The shank 17 is adjustable to regulate the initial positions of the sides 2 and 3, 4- and 5, respectively. The members 2 and. 3 are mounted to slide longitudinally one upon the other by means of the slot 20 and pins 21 while the ends of the members are also permitted to slide upon the pins 22 extending through slots 23 as shown more clearly in Fig. 6. The members 4 and 5 are mounted to slide longi tudinally one upon the other by means of the slot 2A and pins 15 and 25. The links may be provided with perforations a for The operation of my invention may be briefly described as follows :VVith the mold in the condition shown in Fig. 2 the concrete material comprising crushed rock, sand, gravel, white sand or granitoid mixed with cementand water is poured in through, the space 7) between the mold box 1, and the collapsible core. It will be understood that any desired thickness of curb may be made with this apparatus and that any size of curbing may be molded depending upon the size of the mold box 1 and the relative di mensions of the collapsible core. After the concrete has been placed in the space I), the lever 14 isoperated to expand the core and to press the material against the inner wall of the box 1. After the material has be come set, the core is collapsed by moving the lever 14 in the opposite direction after which the collapsible core may be removed. The mold box 1 may be then lifted from the curb and the latter permitted to dry.
