PAVEMENT JO INT CLEANING Filed April 25, 1938 ggkery INVENTOR fi'lmuel Kim ATTORN EYS claimed.

Patented Dec. 26, 1939 UNITED? STATES- ore-ice 7 This invention relates to hand operated tools especially adapted for removing foreign matter from road'surfaces and the joints of concrete roads and the like and has for the primary object the provision of a tool of the above stated character whereby'aperson may with ease and quickness condition a road joint and road surface for recementing or 'calking whereinit'is essential to have the joint or road surface free of 4 dirt and other foreign matterbefore the cement or calking material is applied.

Another object of the invention isthe provision of a portable tool holder requiring only minimum effort on the part of the operator-for its movement over'a road surface and which is equipped with cutting and scraping tools easily brought into place for use and held against loss when not in use. p I

With these and other objects. in View. this in- *vention consists in certain nov'el featuresof construction, combination and arrangement of parts to be hereinafter more fully described and For a complete understanding'of my invention,

reference is to be had to the following desoription and accompanying drawing, in which Figure 1 is a fragmentary'side-elevation'illus trating a tool constructed in accordance with the invention.

Figure 2 is a fragmentary top plan view showing the device adjusted for scraping a road surface or the like. I

Figure 3 is a sectional View taken on line .33 of Figure 1.

Figure 4 is a fragmentary vertical sectional view showing the tool adjusted for cleaning foreign matter from a cement road joint.

Figure 5 is a view similar to Figure ishowing a modification of the present invention.

Figure 6 is a fragmentary top plan view showing the modification.

Referring in detail to the drawing, the numeral I indicates a body of the tool holder and which is of elongated formation and has detachably secured on one end a handle 2.

Formed on the body I adjacent the other end thereof are pairs of shoulders or lugs 3 and cooperating with said lugs in gripping a shank 4 of a tool is,a clamp 5 consisting of a member 6 to fit between the pairs of lugs and overlie the shank of the tool. Integral withthe member 6 are oppositely arranged apertured ears I through which bolts or like fasteners 8 extend.- The fasteners 8 are secured in the body I. The pairs of lugs 3 and the member 6 cooperate in removably securing the tool on the holder orbody l and against "rlat movement thereto'du'ring a clean ing-operatiohZ-- The tools may be of various kinds a'nd shape some" of which are to operate in a road j oint 'for the p'urpose'of scraping or cutting therefrom dirt and otherforeign matter accumulated in the jointso as to prepare' 'the joint to be recementd' or- 'calkedi One of the tools'is in the form ofa' blad'e 9 and having a'shank l0 secured thereto. The blade 9' is 'ofaselected Width having' scraping or cutting edge presented for-movement over asurface' ofa road-to scrape therefrom-foreign niatten'ashoivn in Figure 1. The tools whei'inot in use are removably mounted on the body l-by a clamp II. Asubstanti'ally U- shaped member l2'is'p'ivota1ly mounted on the body-l it adj acentthe securing lugs '3 and has integral'thereu ith spaced 1egs 13 on' whicharejournald rollers" l4 to'ride'the'surface of a road during eitherthe-cutting or' scr'aping' operation.

Formed' on the U-shaped-member IZ -an'd extending upwardly therefromis anj arm [5 to pivoted a flexiblerod" I6 one end'ofwhich is" disposed angularl'y thereto to" enter any onefof' a series-"of socket's' l'l frm'e'din the'body. Said eiid of the'ro'd maybe readily moved from one somer-toanotherfo'r adjust-ingthe cutting action 'of' th'e blade 1 necessary for different joints in'a'-'roadway:- Tl'ie rod adjacent the latternamed end' iscoildto give desired resiliency to said-rod; Secured to the rod I6 is a coil spring l8 and the latter is secured on the body I and acts to urge the rod I 6 in the direction of the body to retain one of its ends in engagement with a socket.

The legs I3 move relative to the body I in accordance with the amount of manual pressure placed on the body. Thesubstantial normal position of the legs I3 is as shown in Figure 1 so as to position the rollers M in a plane slightly below the tool carried by the body so that the rollers may move over a surface with the tool in engagement with the surface. However, when cleaning a crack or joint in the roadway additionalmanual force is applied on the member I causing the legs to swing past and above the tool as shown in Figure 4, still contacting the surface of the roadway with the tool extending fully into the crack or jointso that as the device is moved along the crack or joint foreign matter will be cut, scraped or otherwise removed from the crack or joint. v

Referring to my modified form of invention a tool holder I9 is provided which consists of a member 20 having a shank 2! extending upwardly from one end. The shank 21 is secured on the body I by the clamp 5 and lugs 3. When the body I is disposed in an operating position with the rollers in engagement with the surface of the road the member 20 is disposed substan tially horizontally to the surface of the roadway and has pivoted to its forward end an arm 22. A coil spring 23 is connected to the member 20 and to the arm 22 urging the latter downwardly toward the member 2!. The member 2| is of a bifurcated construction through which a tool 24 may extend. The tool is carried by the arm 22.; The cutting end of the tool when so mounted on the body 5 is disposed in a plane below the rollers for operation in a crack or joint of a roadway and is capable of yielding upwardly if engaged and extending forwardly and downwardly on opposite sides of the body and the tool carried thereby, rollers journaled on said legs to ride the surface of the road, an arm integral with said U-shaped member and extending upwardly and forwardly with respect to the body, said body having a series of openings, a resilient rod pivoted to said arm and adapted to have an end thereof insertible in any one of the sockets.

2. A device for preparing road joints and road surfaces comprising a body, a handle for said body, means for detachably mounting on said body different types of tools, means on said body for supporting said tools when not in use, a substantially U-shaped member pivoted on. said body, legs integral with said U-shaped member and extending forwardly and downwardly on opposite sides of the body and the tool carried thereby, rollers 'journaled on said legs to ride the surface of the road, an arm integral with said U-shaped member and extending upwardly and forwardly with respect to the body, said body having a series of openings, a resilient rod pivoted to said arm and adapted to have an end thereof insertible in any one of the sockets, and

a coil spring connected to said rod and to said body and acting to urge the rod toward the body.

ing means carried by said body, rollers yieldablyand pivotally mounted on said body to engage with a surface, a shank secured on said body by the clamp and extending forwardly thereof in a plane parallel with the said surface supporting the rollers, an arm pivoted to the shank, a tool carried by the said arm, and resilient means co- .acting with the tool and the said shank to yieldably support the tool in a working position and a tool carried by said shank.

, 4. A device for preparing road surfaces and joints comprising an elongated body, a handle connected to one end of said body, clamping means carried by said body adjacent the other end thereof, rollers yieldably and pivotally mounted on said body to engage with a surface,
