MACHINE FOR MOLDING BASES ON FENCE-POSTS.

To (LZZ who n'it may concern).- Be it known that I, CHARLES S. LONG, citizen of the United States, residing in Au rora, in the county of Kane and State of Illinois, have invented a new and useful Im. I provement 1n Machines for Molding Bases on Fence Posts, of which the following is a specification.

' This invention relates to the construction of machines for molding bases of cement or other material onto metallic fence-posts.

My endeavor in the invention has been to devise a construction of such machines adapted to be operated by manual power and which is so simple as to require no skilled labor inits operation and which is so cheap to manufacture as to bring it within the means of the average farmer, so that the farmer, who is the principal user of such posts, will be enabled to provide the metal posts with bases at his home.

The invention consists in the novel construction of parts and devices and novel combinations of parts and devices hereinafter set forth.

In the accompanying drawings I show at Figure 1 an end elevation of my invention, at Fig. 2 a section on the line A A of Fig. 1, and at Fig. 3 a section on the line B B of Fig. 2.

My invention employs a horizontal mold of the proper size and shape for the base of the post, and this mold is divided horizontally along its central plane. The lower half 6 of the mold is formed in the base 7 and the upper half 8 in a movable block 9. The ends of the mold are formed partly by the vertical portions 10, which are attached to or in one piece with the lower half of the mold, and by the vertical pieces 1 1, inclosing the open ends of the upper half of the mold. The pieces 11 are connected together by longitudinal pieces 12, and the pieces 11 and 12 together form a complete frame, which is adapted to rest upon the top of the lower half-mold, being coincident with the latter in shape and dimensions and also adapted to serve as a guide to the block 9 in its movements. At each side of the mold are two uprights 13, arranged opposite each other in pairs and each provided with an overhanging hook 14, the interior of which serves as a bearing for the journals 15 of the eccentric-shafts 16. These shafts extend transversely across the a paratus and are located over the ends of the Specification of Letters Patent. Application filed September 6, 1904. Serial No. 223,327-

block 9, and each shaft is provided with an eccentric 17 and with an operating handlever 18.

Arranged longitudinally of the top surface of the block 9 is a slot 19, in which I place loose rollers 20. These rollers receive the pressure from the eccentrics and communicate the pressure to the block 9, whereby the latter is forced down and creates the pressure upon the plastic material forming the base of the fence-post, and in order to create greater or less pressure it is only necessary to substitute other rollers 20 for those shown, largersized rollers increasing the pressure and smaller ones diminishing it, as will be readily understood. The rollers are seated in the ends of the slot when the eccentrics begin to bear upon them, and they are free to turn with the eccentrics.

The metal portion 21 of the fence-post is positioned in the mold by forming an opening 1n the ends 10 and 11 corresponding to the shape of the post. Thus in the instance shown the post is made of What is known as Y metal, and the ends 10 and 11 are fashioned to fit such shape. If it is desired to use different-shaped metal, of course the supportmg-opening in the end of the mold will be changed correspondingly.

In the use of the apparatus the metal post is positioned as shown and a measured quantity of the cement or other lastic material of which the base is to be formed is positioned in the lower half of the mold, the frame 1 1 12 being preferably in position upon the lower half-mold. The block 9 is then inserted in the frame, and the shafts are placed in the hooks of the uprights, with the levers thrown back from the positions shown at Fig. 2. The rollers 20 being placed in the slot of the block 9 in readiness to engage the eccentrics, the levers are then forced over to the position shown at Fig. 2. In this operation the eccentrics bear upon the rollers 20 and carrv' the block 9 down to the necessary extent to create the reqluired compression upon the plastic materia in the mold. After the compression has been retained for the necessary length of time for the setting of the material the levers are reversed from the position of Fig. 2 and the eccentric shafts removed. This leaves the frame 11 12 and the block 9 at liberty to be lifted off, so that the post, with its molded base, may be then removed.

I posts, having a lower stationary half-mold with closed ends, an upper movable halfmold with open ends, a frame closing the ends of the upper half-mold, and also serving to guide the upper mold, and means for forcing the upper mold down on the plastic material an opening being formed in the end of the lower mold and the frame at the meeting line of the same for the insertion and support of the fence-post.

2. The machine for molding bases on fenceposts, having a lower stationary half-mold with closed ends, an upper movable halfmold with open ends, a frame surrounding the upper mold and resting on the lower one, and serving both to close the ends of, and to guide the upper mold, and means for forcing the upper mold down on the plastic material.

8. The machine for molding bases on fenceposts, having a lower stationary half-mold, an upper movable half-mold, a guide-frame fitted to and resting on the top of the lower mold and serving to guide the upper mold,

and means for forcing the upper mold down upon the material.

4. The machine for molding bases on fenceposts, consisting of a lower stationary halfmold, an upper movable half-mold, a guideframe, manually-operated eccentrics for forc ing the upper mold down upon the lower one, and rollers in said upper mold engaged by the eccentrics.

5. The machine for molding bases on fenceposts, consisting of a lower stationary halfmold, an upper movable half-mold, a guideframe, manually-operated shafts carrying eccentrics for forcing the upper mold down upon the lower one, and loose rollers in said upper mold engaged by the eccentrics.

6. The machine for molding bases on fenceposts, consisting of a lower stationary halfmold, an upper movable half-mold, a guideframe, manually-operated shafts carrying eccentrics for forcing the upper mold down upon the lower one, and loose rollers located in a slot formed in the top of the upper mold and engaged by the eccentrics.

7 The machine for molding bases on fenceposts, consisting of a lower stationary halfmold, an upper movable half-mold, a guideframe, hooked uprights mounted on the lower mold, shafts supported in said uprights and carrying eccentrics, changeable rollers supported in the upper mold and engaged by v the eccentrics.
