MGLD FOR CONCRETE SIGN-POSTS.
Specification of Letters Patent.
Application filed June 24, 1908.
Patented March 16, 1909.
Serial No. 440,074.
To all whom it may concern.
Be it known that I, LEO G. HAAsE, a citizen of the United States, residing at Pasadena, in the county of Los Angeles and State of California, have invented a new and useful Moldfor Concrete Sign-Posts, of which the following is a specification.
The main object of the present invention is to )rovide an improved molding means where y the molding of such. cement posts is expedited and cheapened.
Informing sign posts as for use upon street corners and other places, it is very desirable that the be formed from material that can be readi y provided with sign or other indicating characters and also that the posts will be lasting or not readily destroyed by the elements.
It has been found that metal is liable to rust and decoloration when exposed to the weather, or it is too costly, when formed with sufficient strength and rigidity, to ada t it for use in all places, and. it has also een found that wood is too liable to decay when buried in the earth to provide a desirable means for forming a sign for streets and roadways. On the other hand I have discovered that a very neat and desirable sign post can be formed from cement with the names of the street, or other information, made a permanent part thereof at the time the post is made, either in the same or of a different color to render said name more easily distinguishable.
The accompanying drawings illustrate a street sign made in accordance with my invention, and also the means for constructing the same.
Figure 1 is a perspective view of one form of. 0st or street sign made in accordance wit my invention. Fig. 2 is a transverse sectional View of the mold or former with a post therein. Fig. 3 is a similar view of the mold with part of the side removed. Fig. 4 is a longitudinal sectional view ofthe mold Without the other side pieces. Fig. 5 is a sectional view of the post resting upon the trough, after the front pieces have been removed.
Referring more particularly to the drawings, which are for illustrative purposes, and, therefore, are not drawn to any particular scale, 1 indicates a post made in accordance Withmy invention which may be or" any desired size and height, it being shown substantially square in cross section and of a convenient height for placing it upon or adjacent to the corner of a street or sidewall 2. The post 1 is formed from concrete or similar plastic material and has its upper end pro vided with letters or clurractcrs to indicate the streets, as Oak street and Elm street, respectively. These letters or characters can be formed in the sides of the post in any desired manner, they beiir shown as 1 raised letters located within a sunfien field 3.
But it is evident that they could be formed to project from or be sunken in a plain field or surface without departing from the spirit of my invention.
In forming a street sign or post as above described, I prefer to construct a substantially rectangular box or receptacle from lower or front side pieces 4 and rear or top pieces 5, as shown in '2. The mold or former is preferably held in itsrece )tive position by means of a cradle formed from two base pieces 6, 6, which are held together by means of a clamp, as a-bolt 7 and handle nut 8. The inner or adjacent faces of the base pieces are inclined, as shown at 9, and preferably provided with teeth or projections 10 for enga ing with the side pieces 4 and holding t Lem against slippage.
The upper side )ieces are loosely mounted upon the lower si e pieces and held thereon in any suitable manner, pins 11 being shown which extend down into perforations 12 in the side pieces 4, and also latches 13 which are pivot-ally secured to the blocks 6, 6, by bolts or pins 14. The adjacent edges of the side pieces are in actual contact except the upper edges of the top side pieces 5 which are preferably located at a slight distance from each other, as indicated at 15, and said edges are preferably curved as shown at 16 to give a rounding appearance to the corners of the post as shown at 17. The side pieces 4 are preferably formed substantially as open frames with their inner faces channeled or re cessed, as shown at 18, within which are mounted the dies or matrices i9 for forming the letters or other insignia for giving the desired information. The matrices 19 rest on the shouldered portions of the bottom mcmhers, as shown, so that said matrices can be removed transversely to the planeof said bottom members. This construction has certain advantages over a construction wherein the matrices are removable by slid-:- ing them parallel to the plane of the mold members, as they can be more quickly removed and replaced. The matr1ces 19 are preferably formed in sections, as shown at 20 in Fig. 4, with the desired characters formed u on a portion of them as shown at 21 in Fig. 4, and the others left plain. A suitable cap or end piece 22 is provided for the mold or side pieces with its inner face formed into any desired shape so as to register with the the post, according-to the place the post is to occupy, and said side pieces are then laced longitudinally within the clamps 6. efore placing thematrices in the frames or side pieces 4, the cavities therein, when it is desired to form raised letters, as in the present instance, are filled with plastic material, as
cement, which is preferably of a difierent. color from that of the remaining portion of the 0st so as to be more cons icuous. Af-
ter t e matrices have been fille in this manner and the side pieces placed in the clamp to form a trough like rece tacle, as shown more particularly in Fig. 3, t e trough is then filled with the material, from which the pot is to be formed, substantially even with the up er' edges of the trough or extending asuita le leces distance above the same. The side are then-placed in position upon the sides 4 and secured as shown in Fig. 2, whereby an inclosed cavity is formed with a slight opening left at the u per edge between thetwo upper edges of t e same through which the rest of the material can be inserted to completely fill the mold or cavity and thereby complete the post. After the material, as cement, which I prefer to use, and which may be formed in accordance with any desired formula, is allowed to set or harden, the mold is then removed by taking out the bolts 11 and swinging the latches 13 down into the position shown in Fig. 3. A temporary trough like structure '26 is placedupon the post in place of the side pieces a and the post and trough are then inverted as shown in Fig. 5, and the clamps an side pieces 4 removed. The trou position for retaining the post by means of suitable supports or cradles '27 After the post has remained in this position the desired length of time for the material to become thoroughly set and hardened, the po t this manner it can -consisting oftwo bottom members, cradle gh 26 is held in its upright is' ready to be taken to the place it is to be used and inserted in the ground or otherwise properly secured. By constructing a post in e made as solid and indestructible as rock itself and the desired characters can be formed upon or within it as readily almost as the post could be formed with plain sides without such characters. As there will be no metal about the post to discolor the surface, the characters upon the post will always be plain and distinct, and as the elements can not possibly afiect the post, the requirement of painting or otherwise rotecting the post, as is necessary w th metal and wood, Willbe entirely avoided, and as the ortion of it that is buried within the ground is not affected moisture or otherwise, there will never be any occasion for replacing the post witha new one except in case of actual breakage of the portion that 5 extends above the ground.
Having described my invention, I claim 1 In a mold for forming sign posts from plastic material, basev pieces having their upper ends inclined an serrated, a clamp for holding said base ieces in en port' position, a substantia y rectan ar mol sugiported on said base pieces wit two of its si es engaged with face pieces and provided with means for forming characters on the post, upper side pieces detachably secured to the lower side pieces and having their upper edges at a distance from each other to form an openin longitudinally ofthe mold, and a cap piece or the mold.
2. 111a mold for forming sign posts from plastic material, consisting vof cradle like clamps, a mold on said supports substantially rectangular in cross sectlon and formed from separabl'eside pieces, bolts and latches for securing the top side pieces to the bottom side pieces, and a recessed ca detachably secured at one end of said mold? .3. A mold for cement posts and the like,'
