UNITED sTATns PATENT oFFIoE.

PHILIP J'.HAAS, 0F YORK, NEBRASKA.

rENcE-ros'r MoLD To all whom 'it 'may concern:

Be it known that I, PHILIP J. HAAS, a citizen of the United States, residing at York, in the county of York and State 0f Nebraska, have invented a new and useful Fence-Post Mold, of which the following is a specification. Y

This invention relates to molds for making reinforced artificial stone fence posts, and has for its object to provide a comparatively Isimple, inexpensive mold of this character b v means of which cement fence posts, hitching posts, rail-way ties and the like Inay be conveniently and expeditiously manufactured.

A still further object of the invention is to provide meansl for supporting the reinforcing wires or rods in position preparatory to introducing the cement, concrete orother plastic material within the mold, and means for holding the wires under tension during the formation of the molded product.

A further object is to provide the tension 4device with burs or nutsV having seating notches formed at the intersection of their side walls for the receptionof the reinforcing wires, said nuts being each provided with a convex face to permit the wires to adjust themselves when subjected to longitudinal strains and having al flat face forming an extended cement engagingl surface when the nutsA are embedded in t e' cement and used as anchoring members for-the reinforcing wires.

A still further object of theinvention'is generally to improve this class of devices so as to increase their utility, durability and efficiency.

Further objects and advantages will apear in the following description, it being understood that various changes in form, proportions and minor details of construction may be resorted to within thescope of the appended claims. v

In the accompanying drawings forming. a part of this specification: Figure 1 is a top plan view of a fence post mold constructed in accordance with my invention. Fig. 2 is a longitudinal sectional view of the same. Fig. 3 is a transverse sectional view. Fig. 4.- is a perspective view of one of the wire supporting members or nuts detached. Fig. 5 is a perspective view of a fencepost constructed with the mold, a portion of one end of the post being broken away to expose the adjacent nut. Fig. 6 is a detail horizontal l Specification of Letters Patent. l Patented 0013.26, 1909. Animation mea April 2s, 190s. serialNo. 429,679.

View illustrating a modified form of the invention. Fig. is a perspective view of one of the nuts shown in Fig. 'detached.

Similar numerals of reference indicate corresponding parts inall of the figures of the drawings.

The ilnproved mold, .which may be made in different lengths' and widths, is preferably provided 'with terminal transverse compartments 5 and 6 and intermediate longitudinal compartments 7, the latter being adapted I to receive the cement, concrete or similar plastic material forming the post or other molded product. The endwalls 8 and 9 of the intermediate molding compartment 7 are provided with spaced vertically disposed kerfs .or recesses 10 adapted to receive the adjacent ends of the movable side bars or walls 11. The transverse bar or end wall 8 is rigidly secured to the base 12 while the transverse bar or end Wall 9 is slidably mounted on the base and movablejlaterally Within the compartment 6 when it is desired to release the side walls 11, as will be more fully explained hereinafter.

Mounted for rotation in the end wall S and passing through the adjacent end wall 13 of the compartment 5 are spaced tension devices preferably in the form of rods 14 each having one end thereof bent to form a terminal operating crank or handle 15 and its opposite end threaded at 16 for the reception of the supporting members or nuts 17. The nuts 17 `are formed with spaced seating grooves or recesses 18, preferably disposed at points adjacent the intersection of their side walls, for the reception of the longitudinal reinforcing wires 19, the latter being preferably in the Aform of loops, as shown, and so arranged that the wires will reinforce and strengthen the corners of the post indicated at 20. The nuts 17 are each provided with a convex face.21 thereby to permit the Wires to adjust themselves when the tension devices are operated and are also provided cach with a fiat face 22 which forms an extended bearing surface for engagement with the cement or concrete when said members are embedded in the latter.

Mounted for rotation in the -end walls 23v of the compartment 6 are tension rods 24: similar in construction to the rods 14 with the exception that the former are provided with terminal loops or eyes 25, said rods being extended through suitable bearings in the end wall 9 and having their inner ends .threaded at 26 for the reception of supporting members or nuts 27, similar in construction to the nuts 17 As a means for locking lthe end ivall 9'of the intermediate molding compartments 7 in contactwith the side bars 11V there are providedsuitable catches 27 each having one end thereof pivoted at 28 to the adjacent .end

' 29 of the compartment 6. The locking members or catches 27 are formed with laterally extending stop lugs 30 which'v bear against the end Wall 9 and are also provided with suitable finger pieces 31 bymeans of which the locking members or catches may be moved to operative and inoperative posltion.

Arranged within the intermediate compartments 7 and secured in any' suitable manner'to the base plate or side bars 11 are triangularly shaped strips 32 by meansof Which the post may be formed with inclined or beveled edges 33. The upper edges of the several end walls of the mold are preferably provided with lugs orl projections 34 adapted to engagecorrespondingly shaped seats or sockets formed in the upper section or top (not shown) o f the mold whenl the .top is positioned thereon.

In making the fence posts the reinforcing wires or loo s 19 are positioned on the nuts 17 and the fnsion of the wires adjusted by rotating the operating handles 15 after which the cement, concrete or other plastic dened the Icatches 27 are swung upwardly to material is introduced into the compart- .ments 7 thus holding the wires under tenslon during the formation of the post. Alfter the cement has sufficientlyv set or harrelease position and the end wall 9 moved `laterally, on the base plate 12 within the compartment 6 thus permitting the side walls 11 to ,be swung laterally on the 'base plate so as to permit the removal of the molded product. Before removing the posts from the mold the

rods

14 and 24 are released or disengaged from the nuts thus leaving said nuts embedded in the concrete or cement so as to form anchoring members for the reinforcing loops or wires, the openings in the opposite ends of the post formed by the rods 14' and 19 being subsequently closed by filling the same with cement or similar material.

In Figs. 6 and 7 of the drawing there is illustrated a modified form`of the invention each Aprovided with a square portion or reinforcement 38 having an opening formed therein for the receptlon of the end of the adjacent. loop 37., the loops being held in engagement with the nuts by means of suitable pins 39, which bea'r against the enlargements 38, as shown.

It Will thus be seen that the tension of the wires 19" may be eectedwithout rotating the nuts 17',

this result being accomplished by reason of the swivel connection between the rin-gs 35v for reinforcing and strengthening the post.'

Whilethe vdevice is principally designed for making fence posts, it is obvious that the same may be used with equally good results for making rail-way ties, bitching posts, w1ndows1lls, rural mail box posts,

sign posts or wherever a device of this kind is found desirable.

Having thus described the invention what is claimed is:

1.l A mold including terminal and inter mediate compartments, one of which forms a molding chamber, said intermediate compartment being provided with movable side walls and a sliding end wall, tension devices passing through the terminal compartments, and locking members pivotally mounted within one of the terminal compartments and bearing against the sliding end wall of the intermediate compartment for locking said end wall in engagement with the side walls.

2. A mold including intermediate and terminal compartments, .one of which constitutes a molding chamber, said intermediate compartment being provided with detachable side Walls and a movable end wall, a supporting member disposed within the intermediate compartment for engagement with a reinforcing wire, threaded rods passing through the terminal compartment and operatively connected with the supporting members for adjusting the tension of the reinforcing wire, locking members pivotally mounted within one of the terminal compartments and each provided with a laterally extending lug adapted to, engage the movable end wall of the intermediatecompartment,l and finger pieces carried by the locking. members for moving the latter to operative and vinoperative posltions.

In testimony that I claim the fore oing as my own, I have hereto aiiixed my signature in the presence of two witnesses.
