PARTING STRIP FOR CEMENT STRUCTURES.

Application filed September 27, 1924. Serial No. 740,252.

To all whom it may concern:

Be it known that I, lVILLI'AM C. BURRELL,

a citizen of the United States, residing at Kankakee, in the county of Kankakee and State of Illinois, have invented certain new and useful Improvements in- Parting Stripsfor Cement Structures, of which the following is a specification.

The invention relates to improvements in parting strips for cement structures, having especial reference to roadways.

One of the objects of the invention is ,to provide improved means for supporting the strip in vertical position.

Another object is to provide improved means for joining adjacent ends of the strips by use of notches in the respective ends that may be keyed together by use of a strip-supporting pin. 7 e

A further object is the provision of chairs or shoes at intervals to afford a wider base surface'for the strip to better resist tamping and ,Ineans to key the shoe or chair to the strip by operation of the supporting pin.

A further object is to drive the supporting pin into the ground at an angle to a vertical plane in which the strip is located toiproduce a wider holding base forthe.

' strip.

Another object isto provide a yielding 0r resilient removable member to be tempo-- rarily supported by the strip and to be sub sequently removed to provide an opening along'the strip t9- be thereafter filled with another suitable plastic.

Other objects and advantages will become apparent from a consideration of the fo-llowing description when taken in conjunction with the drawings, wherein Fig. 1 is an elevation of a parting strip showing the manner of connecting the ends of-two adjacent sections and showing one fprm of removable member supported thereon having openings on line 4-4 similar to Fig. 5.

Fig. 2 is a similar view showing a removable memberof a slightly different form. The strip has openings on line 3-3 similar to Fig. 3.

Fig. 3; is va cross section thru the stripshowing the manner of supporting it by pins driven thru onev opening thru the wall into the ground. I

Fig. 4 is a similar'view of a broken away member showing the strip supported upon In all the views the samereference oharac ters are employed to indicate similar parts.

The parting strip for cement structures is used to define the parting line between adjacent portions of the structure, such as roadways, and the like, for substantial separation of said portions to permit independent movements of said portions due tocontraction.

I have shown an embodiment made of the strip 10 made of sheet metal having a longitudinally extending outwardly projecting channel havingan upper wall 12 and a lower wall 13 and having upper and lower vertically aligning Walls 14 and 15. i

In Figs. 2 and 3 the angular wall 12 is perforated at 16 and the wall 15 has an 'outturned lip 17 which has a perforation 17 to receive the supporting pin 18. The pin 18 is preferably. driven thru these perforations 16 and 17 into "the ground at an angle to the vertical walls 14 and 15 to thus provide abetter base support.

In Fig. 4 the perforated lip 17 is outturned from the wall 14 and the pin opening 19 is made thru the inclined wall 13.

In Fig. 4 a shoe 20 lies closely in contact with the walls 13 and 15, and has an aligning perforation to receive the pin 18. The shoe has an outturned foot 21 upon which the lower edge of the strip rests, to provide a more extended base forthe strip. The foot 211s also perforated to receive the pin 18. In Figs. 3 and 4 the strip 10 has only one perforation in thefchannel wall thru which the pin 18 passes. The lips 17,-as shown are outturned from the'vertical wall 14 or 15. 'In Fig. 5 the strip'lO has an elongated perforation at the apex of the walls 12 and 13, thru which the end 22 of'the shoe .23

the ground, to support the strip in vertical position as shown.

Brackets 32 are placed at intervals on the wall 14 to support the removable strip 33. The roadway is made flushwith the upper surface of 33. When the cement sets an'l' becomes hardened, the strip is removed and the channel left by removal of the strip 33 may be filled with another plastic substance, such for example as asphalt-um or cement of a contrasting color, to provide a distinguishing stripe along the center of the roadway.

The strip 34 is not so wide as the strip 33 and it may be mounted directly upon the metal parting strip. The strips 33 and 34 are yielding resilient compressible material, such for example as soft rubber. They may be removed conveniently and quickly and usezlover many times without 1l]]U1y.

Where the-termf'soft rubber is used in the claims, the expression is a term of definition and not limitation, as any other material having similar desirable charac-' teristics may be substituted as an equivalent. c

Having described my invention what I claim as new and desire to secure by Letters Patent, is

1. A parting strip for cementstructures having an outturned perforated lip and an aligning perforation thru the body of the strip to receive a supporting pin.

2. A parting strip for cement structures bent to form a channel, one wall of which is perforated and a spaced outturned lip having an aligning perforation, said perforations arranged to receive a strip-supporting pin. I

3. A parting srtrip for cement structures providing two a igning perforations and a shoe upon which the strip is to rest, said shoe having a perforation arranged to align with the perforations in the strip to receive a supporting pin for the strip.

l. A parting strip for cement structures providing two aligning perforations to receive a strip-supporting pin and a shoe having a perforation arranged to receive said pin and by 'which the shoe is held to the strip.

5. A parting strip for cement structures having a longitudinal channel formed in one side, one wall of said channel having a perforation and a perforated lip outturned from the body of the strip, said perforations arranged with respect to each other in a plane at an angle from a' vertical plane passing transversely thru said strip.

6. A parting strip for cement structures,

having its ends notched which notches form locking members when saidends are overlapped and a strip-supporting pin passing thru said overlapped ends to lock the strip sections together.

7. A parting strip for cement structures having a laterally extending channel, thewalls of the channel notched at its ends, each notch having a larger opening at its inner end and a pin passing thru said enlargelopenings whensaid ends of two strip sections are overlapped and said enlarged parts are in aligning register.

8. A parting strip having a laterally extending channel and having two openings out-of vertical alignment to receive a pin to anchor the strip to the ground.

9. A parting strip having a laterally extending channel providing a perforation to receive a' pin, anda pin passing thru said perforation and located in a plane'angularly related to a vertical plane in which the strip is located.

In testimony whereof I hereunto set my hand.

WILLIAM C. BURRELL.
