EDWARD J. CONDON, OF DIXON, ILLINOIS.

CEMENT-POST MACHINE.

To (ZZZ 20.60122 it may concern:

Be it known that I, EDWARD J. Common, a citizen of the United States, residing at Dixon, in the county of Lee and State of illinois, have invented certain new and useful Improvements in Cement-Post Machines, of which the following is a specification.

My invention pertains to concrete post machines, and aims to provide a simple and novel device whereby such posts can be rapidly and cheaply produced.

In the manufacture of fence posts of the character mentioned it is usual to embody therein some reinforcing means, such as wires or rods, extending through the same, and it has been demonstrated in practice that to get the best results such reinforcing means must be located in a particular position in the post.

In my invention 1 provide a mold, and means for filling the same by two or more operations, the locating of the reinforcing means being accomplished between the operations, the amount of material delivered to the mold by each operation being predetermined, and capable of being increased or diminished, as desired.

In the accompanying drawings: Figure 1 is a plan view of my invention. Fig. 2 is a front elevation thereof. Fig. 3 is an end elevation thereof. Fig. at is a vertical crosssection, on the line 0-f6 of Fig. 1. Fig. 5 is a detail, showing one of the wedges 21.

Similar parts are indicated by corresponding figures of reference throughout the several views.

1 represents the frame of the machine, preferably constructed of metal, and to the rear part of which are pivotally attached end pieces 2-, between which is secured a hopper or receptacle 3. At each end of the machine is a bar 4:, upon which are supported cross-pieces 5 and 6, above which is supported a plate 7, such plate being also located just beneath the receptacle 3. Be tween the plate 7 and end-pieces 2 is slidably mounted a bar 8, the ends of which project beyond the end-pieces and are connected by links 9 with a pair of hand-levers 10, fulcrumed on brackets 11, fixed to the rear part of the frame 1. By the operation of the levers 10 the bar 8 can be moved forwardly or rear-wardly, as desired.

Secured to the front face of the crosspiece 6 is a plurality of brackets 12, by means of bolts 13 passing through such Specification of Letters Patent.

cross-piece and through vertical slots 14: in such brackets. Upon the brackets 12 is supported a pallet 15, of suitable shape, one edge of such pallet being in contact with the face of the cross-piece 6. The bars 4 are projected forwardly beyond the frame of the machine, and pivotally supported on such extensions is a front board 16, adapted to be swung upwardly against the outer face of the pallet 15. In such position the board 16 is held in place by means of notched arms 17, pivoted to the frame 1, and engaging plates 18 on the ends of the board 16. Upon the pallet 15 are supported endpieces 19 and 20. The upper part of the cross-piece 6, pallet 15, front board 16, and blocks 19 and 20 comprise the mold in which the post is formed.

In operation, the material from which the posts are to be produced is placed in the receptacle 3 in a plastic condition, and the bar 8 moved rear-wardly, permitting a portion of the material to pass downwardly upon the plate 7. The bar 8 is then moved forwardly, carrying the material which is between the lower end of the hopper and the plate 7 into the mold at the front of the machine. The bar is then again moved rearwardly, and the operation repeated until the mold has received the desired amount of material. Between certain of the filling operations the material in the mold is provided with suitable reinforcing means. For example, if it is deemed expedient to have such reinforcement located at a point which will equal one-fourth the thickness of the post, the first operation will fill the mold to onefourth of its depth, whereupon the strengthening rods or wires will be placed therein. With two more operations the mold is filled to within one-fourth the distance to the top thereof, and additional wires are located therein, after which the mold is filled by one more movement of the bar 8, and the material in the mold subjected to a tamping process to form the same into a compact mass. In delivering the several quantities of material to the mold, due allowance must be made for the shrinkage thereof caused by the tamping operation.

It will be apparent that the amount of the mixture which is delivered to the mold by one operation of the bar 8 is determined by the movement of such bar, and that if the rearward movement of such bar is increased, the amount of material delivered will be increased, and vice versa. the GHLjDiGCG-S 2 being piviear their rear ends, there is at all times a cieza e eenraci: between the lewer ei'ige the hopper a id the bar 8, caused by the h (11 110 hopper and centenrs.
