REINFORCING DEVICE.

Specification of Letters Patent.

Patented June 22, 1909.

To all whom it may concern:

Be it known that we, WILLIAM F. KERLIN and EDWARD W. BOWEN, citizens of the United States, residing at-Rockfield and Delphi, in the county of Carroll and State of- Indiana, have invented certain new and use-- 'ful Improvements in Reinforcing Devices;

and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the'art to which it appertains to make and use the same- This invention relates to new and useful improvements in reinforcements for plastic material when molded in various shapes.

It isfan object of the invention to provide a novel device of this character employing a reinforce consisting'of a sheet of metal provided with blades or flaps extending in varimake effective resistance to any jar or pres-- sure coming upon any part of the body when completed.

It is also an object of the invention to provide a novel reinforcement for a plastic post wherein said reinforcement projects beyond a face of the post to produce a means for the attachment of wires. It is also an object of the invention to pro: vide, in the projected portion .of the reinforcement elongated openings, each having in communication therewith a slot or slit from the outer edge of the projected portion, said elongated openings permitting the metal 'to be swung to one side so as to admit the lateral wires of the fence.

It is also an object of the invention to rovide a novel device of this character w ich be simple in construction, efiicient and advantageous in practice and comparatively inevrpenslve to manufacture.

1th the above and other objects in view the invention consists in the details of construction and in the novel arrangement and combination of parts to be hereinafter more particularly referred to.

In describing-the invention in detail reference will be had to the accom anying drawmgs forming part of this spec' cation, wherein like characters of reference denote corresponding parts in. the several views, and in which, s

Figure 1 is a view in perspective of the reinforcement constructec according to the present invention when to be applied to posts. Fig. 2 is a view in cross section of a mold for forming a plastic post with the reinforcement embedded therein. Fig; 3 is a view in cross section of a modified form of the invention. Fig. 4 is a view in perspective of the reinforcement employed in Fig. 3, and, Fig. 5 is a view in perspective illustratin a shghtly modified form of-Fig. 1.

' n the drawings 1 denotes a strip of metal of proper length and Width having a major portion 2 projected, said major portion ex tendin from the upbper end of the stri when a plied to a oint elow the center t ereof. The remaining portion of the strip, or that ortion not pro ected, is adapted to be embedded withln that portion of the post which constitutes the base thereof. At predetermined intervals the opposite portion of the strip 1 is slitted to form blades 3, said blades having their ends bent u on themselves to form eyes or sleeves 4. he blades 3 are arranged in succession one angular with relation to the other, and it is referred thatthey be bent or positionedas s IOWII' in the drawings wherein one blade is in the same plane with the body 1, while the next blade is bent to one side thereof .upon a suitable angle,

While the next blade is in thesame plane with the first named blade. bent in a direction opposite to that of the second named blade on a proximately the same degree of angle. This "arrangement continues the entire length of the body 1, and it has been found best that the blades be of such Width as to permit a straight blade to be located at both ends of the strip.

In order to permit the reinforcement to give additional strength to the post orother bodyformed of plastic material, when ap lied, there are assed through the eyes or s eeves The next blade is 4' of the b ades the wires 5, which may be secured thereto in any desired manner, but preferably. by brazing. By the use of these wires the post is very materially strengtlk ened, as it permits effective-resistance to any jar or pressure coming. u on any part of the post, as is believed to e apparent. The wires secured to the center or straight blades will Withstand any pressure or jar on the rear of the post, while the wires secured to the.

side blades will withstand any pressure or jar on the sides of the post. The reinforcement is further rovided with. the wires 6which are positioned 3, and interposed between said stra ght blades and the side blades in proximity to the junction of the side blades with the body 1. These wires 6 are also brazed to the various blades 3 with which they contact. By

the employment of these wires 6 the reinforcement is greatly strengthened the entire length thereof, but more especially, when-applied to the post, at the breakof the post or ground line when the post is set. t

It is believed well to state that the 'res 5 and 6 extend the entire length of the body 1, but it has been desired that certain of the wires-Sand 6 be projected above the top of v projected portion 1s provided wt clined slit 9., These elongated openings are for'the retention of the wires forming part of the fence and by having the slit extended from therouter edge of the projected portion '2 above the'openings 8 the slit does not in any way decrease the strength of the metal immediately in.fr0nt of the opening 8. By having the opening 8 elongated, the metal can be sprung to .one side so as to admit the lateral wires of the fence which can be readily suitable metal is slit at intervals pressed into said openings, The slits 9 being above the res ective openings and cut to the .rear edge an above the openings prevents the wires when in the o enings-froni being forced out through the s its, a feature which in the practical use of the post is found most essential.

In-Fig. 3 is shown a cross section fof a slightly modified'form of post, such post as is intended to be employed as a tele 'ra h pole, or the like, In this instance the %0 y 10, of along its opposed longitudinal id'ge to form blades 11 which are bent in almanner similar tojthat disclosed in Fig. 1. This reinforcement is also provided with reinforcing wires :12 and 13, arr an ed similar to the wires 5 and 6 (hereinbe ore referred to), respectively.

In Fig. 5 is disclosed a form offlreinforce ment somewhat similar to that in Fig. 1, ex-

' cept that there is a straight blade 14, alblade 15 bent angularly to the left thereof and then a blade 16 bent angularly to the right thereo 'when the succeeding blades'then con} to either side of the straight blades several rows of ,tinue downwardly in successionin a similar manner. In other respects the invention is the same in every way.
