nxrnnsron JOINT. I
I application filed December-.3, 1920. Serial No. @27344. i
To all whom it may concern:
Be it known that I, Hummer R. KonsTnR,
a citizen of the United States, and a resident of Bond Hill, in the county of Hamilton, Stateof-Ohio (whose post-office address is Yarmouth and Oberlin Avenues Bond Hill,-
Cincinnati, Ohio), have invented new and useful Improvements in Expansion Joints,
2 of which the following is a specification.
My invention relates to, an improvement in expansion j omts for use in highways, con-' cret-e or otherwise. Heretofore in the use of expansion joints, more espeeiallynexpansion joints formed ofa bituminous material, or a bituminous compound and a supporting or reinforcing material, it has been found that when; in place the adjacent ends did not retain their positions. The adjacent ends Would tilt in opposite directions, would overlap, one remain vertical and the other tilt at an angle thereto, etc. This gave dissatisfactiontending to disrupt thepavement when expanding, etc. Attempts have been made to overcome these objections by i airing the joints-longer but due to the nature of the material these attempts have 7' not proven satisfactory. I have discovered adjacent joint. 7
ln the drawings in which like letters re that these defects and fobjections may be overcome by making expansion joints of two or more sections provided at the ends with means, either separate or integral withthe sections, for supporting the adjacent ends in contact and in alignment so that eachtwo or more sectitons of joint are substantially one and the position of one joint at the end is the same position as the end of the next fer to like parts:
Fig.1 is a top view of two sections of an expansion joint showing one form of my invention.
Fig. 2 is a top view of Fig. 1 showing the joint ready to be installed.
' Fig. 3 is a side view of Fig. 2.
Fig. 4 is a cross section of Fig. 2. Figures 5, 6, 7, 8, 9,10, 11, 12 and 13 are modifications of my invention. i
Referring to the drawings I have shown therein my invention applied to expansion joints using the form of expansion joints in whicha bituminous material and a reinforcing material is used but I would have it understood that my invention is equally applicable'to other forms of expansion joints as a hinge while at the same time it perature changes.
wherein similar difi'iculties are met with. In the drawings A is a bituminous compound, preferably asphalt and any suitable filler, B B 1s a reinforcing material preferably felt saturated, or impregnated, depending 4* upon the felt used, with an asphalt. Such expansion joints are shown in U. S. Patent No. 1,339,094- to Ford C. Bowman and form no part of my invention. These joints in the preferredform of my invention 1 at tach .to each other at their adjacent ends, by cementlng with any suitable cement D, althoughI prefer a waterproof cement such as an asphalt cement, strips C, 'C of flexible material such as a strip of felt saturate: with asphalt or similar material saturated or impregnated with a bituminous material. These strips C, C are preferably arranged, on both sides of the adjacent sections of expension oint and may be attached thereto at by cement D as stated, or may be stapled by staples E, E or by both cement and staples; To enable ready handling and transpertation of these joints I apply the strips C. C at the factory, leaving one end of one strip C free from one side of the end of one of the joint strips as shown in Fig. 1. This enables the joints to be folded upon one another for shipment. The strips C, C by reason of the nature of the material, it being a felt saturated or impregnated with asphalt, is flexible and elastic and readily acts also corresponds in action with the joint under moye'ment of the pavement due to expan sion. and contraction resulting from tem- In some forms of joint the bituminous material A extends above the reinforcement 13 and in such case 1 prefer to leave the strips 0, C of substantially the same Width as the reinforcing member B. When the jointhas arrived on the job and is about to be installed the workmen then coat the free end of the strip C with cement Band placing the adjacent ends of the joint together the free endof the strip C is pressed against the strip B of the joint so as to cement the strip (3 in place as shown in Fig. 2 after which the staples E, l) are driven in. Gf course the cement could here again be dispensed w and on staples used or staples omitt and 0 only used. if desired the worlnnencou is some cement between the adjacent ends the joints where they touch to cement them and prevent any objctionahlspaces.V The strip (1 could he placed on one side only of the joints in which event, on the oh,' the .woi-kman would merely have to unfold the w'ljaccnt sections of joint. v
v in the modification sl'iown in Fig; 5-1 have shownn joint with a feltoi metal strip G in the center of one end of one section of expansion joint and ettechedto the outer surface of the next adjacent section. In Fig. 6, I have shown a metal strip C embedded in the end of one section of joint and adapted to he forced into the next section.
in Fig. 7, l have show'n'e similar modification exceptthat -m place of being embedded into the joint the strip v(. IS formed at one end so as to enclose two or more sides of the hoth or in any suitable manner.
end of one section of the joint and the other endof the strip (J is adapted to be forced into the adjacent end ofthe next section of joint. n A
In Figures Send 9 the modification is in the form of-a channel C which encloses tvio sides-ct the ends of adjacent sectionsflof joint. and the bottom thereofi lirthis modi;
out of the metal or formed at the ends-of the plates by turning up the metal, adapted to be pressed into the sections of joint to support, same in desired'position. The teeth 6% may he of varyinglength or shape and either integral with or separate from the plate F. If separate any suitable staples or other means may he used forholding it in. place.
What-(I cleim- 1. An expansion joint comprising e plnrality of sections composed of a plastic mass and a strip otfiexible waterproof material 1 connecting adjacent ends of same. v Z-An expansion joint comprising a plurality of sections and a waterproof hinge connecting adjacent ends of some.
3. A i-ality ofsection'scomposed in part of a massof plastic material and a separate strip of flexible material connecting adjacent ends oi same. 4
4. An expansion joint comprising a pluralitiy of sections composed in partof a mass of p ustic material nndeparatcmeans confleeting adjacent ends of some, and means sections.
n expansionjoint cdmprising a plufor attaching, the aforesaid means t said 5'. An expansion joint composed of e phitalitrUfs'tidnSof board like" plastic mw teriel and means indcpe'ndentof'butfixediy attached to one of said sections for holding the adjacent end ofthe next section'in alignment with eztchother,
6;"An iz'piinsion joint ccmpoed of 'afphr relity of-sections' of board like plastic niw terialand'gneans arranged on each side of said sections end'fixedly attached to one-0f the two abuttingeections' for holding the adjacent ends'of with each other.
'7. An expansion joint formed of'a plurality of separate sections f plastic waterproof said sections in alignment material and means fixedly atteched to one of the two abutting sections for holding the adjacent ends of said sections together so as to reteinsaid adjacent sections in alignment.
In testimony whereof,
1 have signed my name to this cification.
