the marking element is a roller and the roller is supplied with a marking material such as a uid by providing a container carrying a suppljT of fluid and an applicator that receives the material from the container and applies it to the roller.

The various objects and features of my invention will be fully understood from the following detailed description of typical preferred forms and applications of the invention, throughout which description reference is made to the accompanying drawings, in which:

Fig. 1 is a perspective view of a typical form of the invention, showing it in operating position on or over a pavement, and inengagement with the curb at an edge of the pavement. Fig.-

2 is an enlarged side elevation of the device. Fig. 3 is an enlarged detailed sectional view taken as indicated by line 3 3 on Fig. 2. Fig. 4 is a detailed sectional view taken as indicated by line 4 4 on Fig. 3. Fig. 5 is an enlarged detailed sectional view taken as indicated by line 5--5 on Fig. 1. Fig. 6 is an enlarged plan view of a portion of the structure taken as indicated by line 6-6 on Fig. 2, and Fig. '7 is a view illustrating a second or modified form of marker, portions thereof being shown in section.

Referring first to the form of the invention` illustrated in Figs. 1 to 6 of the drawings, the device involves, generally, a frame A, supporting means B for the frame, a handle C, preferably on the frame, guide means D on the base portion of the frame, a marker E, and means F supporting the marker from the frame.

The frame, in its preferred form, involves a body II), an elongate base I I, and elongate braces I2. The body I0 is preferably an elongate member, tubular in form, and the base II may be an elongate member likewise tubular in form. The inner end of the body I0 is joined or xed to the base and may be midway between the ends of the bas. The braces I2 are preferably elongate tubular members and their outer or forward end portions are Xed to the body III at I6, which point is intermediate the ends of the body I0 so that the body has a forwardly projecting portion I'I forward of the braces I2.

The supporting means B preferably involves inner'and outer supporting rollers and in a preferred arrangement there are two inner supporting rollers and one outer supporting roller. In the case illustrated there are two inner supporting rollers 2Q and they are located at the end portions of the base I I of the frame, or at the corners where the base connects to the braces I2. In accordance with the invention, the rollers are located below the frame and on horizontal axes in vertical planes normal to the longitudinal axis of base II. In the case illustrated, each roller 2li is carried by a bracket mounted on or secured to the base II of the frame. The bracket shown is U-shaped to partially embrace the base I I where it is 'lXed or joined thereto, and it has spaced depending arms 22 between which the roller is located, the roller being carried by a pivot pin 23 that extends between the arms.

The single outer supporting wheel 3D is preferably supported on or from the forwardly projecting portion I'I of body I Il and a preferred form of mounting means involves a collar 3| carried on thev body portion I1, an arm 32 projecting from the collar and a pivot 33 carried by the arm and supporting the roller 3Q. 'I'he collar 3l is rotatable and may be shiftable longitudinally on body portion I 'I and a suitable means such as a set screw 35`is provided for releasably setting the collarin any suitable position on or around the body portion II. Through the mounting means just described, the outer supporting roller 30 can 'be adjusted to various positions vertically relative to the frame or to the outer end portion of the frame.

The handle C may, in practice, vary widely in form and construction and is preferably a, structure carried by the frame A. In the case illustrated, the handle C involves two like elements each involving a shank 40 and a grip 4I. The shanks are shown fixed to the body III at points spaced apart longitudinally of the body, and they are shown as extending upwardly and somewhat toward the rear side of the structure, so that they carry the grips 4I so that they project toward the side of the device at which the operator is located when the device is being operated, as in the direction indicated by the arrow X in Fig. 1.

The guide means D involves curb engaging rollers and, in a preferred construction, there are two such rollers and these are located at the ends of base II of the frame or at the corner where the base I I joins the braces l2. In accordance with the invention, the curb engaging rollers 56 are on vertical axes and are arranged relative to the base I I of the frame so that the base is supported in a position spaced from e, curb 60 or other like element. In a typical situation, the apparatus is to be operated over a pavement P at one edge of which there is a curb 6I), and in such case the supporting rollers hereinabove described rest on the pavement while the curb rollers 5I) engage the face 6I of the curb,

In a preferred construction, the mounting for each curb roller 50 involves a connection between the roller and the frame which provides for adjustment of the roller relative to the frame. In the case illustrated, each roller 50 is supported by a stem B5 slidably carried in a guide I2 of the frame and the stem carries a yoke 6B in which the roller 5|] is located, the roller being supported on a pivot B'I which is carried. by the yoke. The stem is preferably slidable and may be rotatable in its supporting brace and a suitable means such as a set screw 68 is provided for setting the stem in the desired position relative to the frame or supporting brace. Through the construction just described, the curb engaging rollers 50 can be adjusted to various positions relative to the frame to meet road or working conditions, as circumstances require. In a typical case or situation, the curb engaging rollers 50 will be set so that the base I I of the frame is spaced but a short distance from the curb and is parallel therewith, in which case the body Ill of the frame is normal to the curb. If desired, however, the stems 65 of the mountings above described can be positioned so that the rollers 5I! support the base II at various angles relative to the curb, or at various distances from the curb.

The marker E is shown as kinvolving a marking element 'III and a carrier II supporting the element. -In the particular case under consideration, the marking element 'I0 is an elongate body of chalk or the like and the carrier 'II is a tubular element in which the stick of chalk is slidably mounted. A suitable means, such as a helical compression spring 12, may be provided in the carrier 'IIJ behind or at the inner end of the chalk so that the chalk is cushioned. This construction allows for shifting or variation of the chalk in the holder as the apparatus operates so that the chalk is maintained in proper marking-engagement with the pavement P. Y

The means F supporting the marker from the acceder frame preferably provides for adjustment of the marker relative to the frame so that the angle' or position of the marker relative to the pavement P can be adjusted and so that the spacing of the' marker from the frame can be adjusted. In` the form of the invention illustrated, the means F involves a rod @3' slidably carried by the frame and the rod carries the carrier ll. of the marker. In the case illustrated, the rod 8U is slidabl'y engaged in the frame body It so that it can be shifted longitudinally therein or can be' rotated therein as circumstances require.l A suitable means is provided for setting the rod. in suitable adjusted position. In the case illustrated, a releasable means in the form of a set screw 8l is provided for this purpose. The marlier above described can be mounted on or secured to the rod 89 in any suitable manner.4 In the case illustrated, a collar 33v is provided ony the marker, that is, on the carrier of the marker, and the collar 83 is slidable and rotatable on' the rod 80. Through` this construction, the marker can be slid along the rod to any desired position and can be rotated on the rod as desired. A suitable means such as a set screw S is provided for setting the collai` in the desiredposition on the rod.

In the form of marker illustrated in Fig. 7, the carrier 'Ila supports the collar 83 that receives the rod 80 and it has a lower arm 85 that carries the marking element 7&1a and it has an upper arm 8'6 that carries a means for supplying material to the marking element. The marking element 'lllai is in the form of a marking roller mounted on the arm 85 by a pivot pin 8l, The means carried by arm 86 is adapted to supply marking material to the roller and is shown as including a. container 88 carrying a suitable supply of marking material M and an applicator1 39 that may be in the nature of a brush which receives material from the container and. applies it to the roller, In the particular case illustrated the unit formed by the container 88 and the brush 39 is mounted on the arm 8G through a means 90 which provides for adjustment of this unit relative to the roller so that the desired contact or engagement may be maintained between the brush and the roller.

From the foregoing description it will be apparent that the invention provides a frame which is very simple in form and construction. The frame, together with the handle means C, may be a rigid or unitary structure formed entirely of tubing so that it is light and at the same time strong and durable. The supporting rollers of the means B are arranged or related to advantageously support the frame from or above the pavement P and by adjustment of the outer roller 30 the outer end portion of the frame can be adjusted relative to the pavement and thus vary the position of the marker-carrying portion of rod 80 above the pavement P. The guide means D is very simple in form and is highly effective in action. The curb engaging rollers can be adjusted as circumstances require and they are located so that they are spaced a substantial distance apart longitudinally of the curb and thus provide an effective guiding engagement between the device and the curb. In practice, the marker or markers that may be carried by the rod 89 can be readily set or adjusted to meet working conditions, and in the case shown in Fig. l' the marker will provide an eiective chalk mark 95 along the pavement P when the structiire is operated along the pavement and in engagemient with" the curb in the direction indicatedby the arrow Xin Fit.y l'. When the mark.

ing. means shownin Eig.y '7. is. employedv the mark applied to the pavement may be i'nlthenatureof a painted lineA or mark which is more` permanentl than a chalk. mark.
