Feb 26, 1935. K. v. EKLOV UNIVERSAL PAINT STRIPING DEVICE Filed June 15, 1933 2 Sheets-Sheet 1 INVENTOR.

Patented Feb. 26, I935 UNITED STATES PATENT OFFICE 4 Claims.

My invention relates to a paint striping device, and is an improvement over my former striper as described in my former application Se rial No. 625,741, filed July 29, 1932.

The object of my invention is to produce a universal striper adapted for making fine striping lines on various positioned surfaces, the strip ing device being capable of functioning in several different positions.

Another object is to produce a paint striping device having the liquid paint container rotatably mounted on the striping unit and capable of complete rotation thereon to any position about the striper axis.

A further object is to produce a striping device having an angularly positioned paint container attached to the mounting collar by swiveled means, capable of inclining said container in any desired direction with the striper axis, for causing the liquid paint to flow therethrough for the various positions of the striping unit.

A still further object is to produce a universal paint striping device provided with an automatic feed valve for controlling the flow of liq- 25'- uid paint when the striper is not in use, actuated by an adjustable guide member connected thereto.

Another object is to produce a universal paint striping device that is simple in construction, 30- easily and efficiently operated and that can be manufactured at a very low cost. I

These several objects are attained in the preferred form by the construction and arrangement of parts as are more fully hereinafter set 2 forth.

It is to be pointed out that while the general principle of the striping unit per se, is similar to that of my former device referred to in the aforementioned patent application, it is im- 10 proved and modified by the universal and auto-' matic features of both the rotatable feed collar and attached swiveled paint container, together with the automatic feed valve and connected movable guide, and my invention herein resides principally in the new combination of these units and their connected operating elements.

Similar parts on all drawings are marked by similar numerals or. letters.

In general my device comprises a tubular paint striping unit, of any chosen design or type, but formed with a centrally located liquid paint passage aximetrically therethrough, and provided with an annular feed ring rotatably mounted on the inner end thereof. The feed ring carries a paintcontainer swivelly mounted thereon and formed with a liquid paint passage opening into the striper unit central passage, and is provided with a regulating valve therein actuated by displacement of a movably mounted guide unit along the striping unit nib.

I will now describe more fully the detail construotion of my device, referring to the drawings and the marks thereon.

The striping unit 1 is made of metal comprising the m'b a and the body section b which is preferably formed of a series of stepped cylindrical sections 0, d and 6, all concentric about the same axis. The nib a is formed witha short cylindrical disc chamber 1, open at the nib end, and carries rotatably mounted therein a pinned surface striping disc g, said disc having one edge projected out of the edge opening of the inclosing chamber 1. A curved disc spring h is also mounted within the disc chamber 1, partially surrounding the disc g, the spring ends coming in contact with the pinned disc surface at the chamber opening. A central paint channel k is formed lengthwise through the body section 1), positioned concentric with the striper unit axis and leads into the disc chamber ,1. A more detailed description of the preferred striper nib herein shown, is set forth in my former patent application, Ser. No. 4%,283, filed September 25, 1930, and while I illustrate a similarly constructed striping nib in this invention, it is to be understood that any other suitable type of striping nib might be substituted therefore in this described improvement. Slidably mounted on the outer surface of the striping unit body I), is a hollow guide thimble 2, also made of metal and preferably formed in a cylindrical shape having an end flanged collar 1', and formed with an inner end shoulder Z around the inner end thereof, said shoulder Z fitting over and slidably mounted on the cylindrical body section c of the striping unit, the sliding movement thereon being limited by the adjacent cylindrical body section d. The outer end of the guide thimble 2 being slidably mounted over the end body section e, and thereby forming a chamber recess m between the surfaces of the thimble 2 and the inclosed striping unit body b. Within the recess chamber m is mounted a compression coil spring 3 which engages the oppositely positioned end shoulders Z and e of the guide thimble 2 and striping unit 1 respectively, the reaction of said spring retaining the engaged members in an open position when unrestrained by manual pressure thereon, as indicated in the Fig. 5 of the drawings.

Slidably mounted over the cylindrical guide thimble 2, and splined thereto, is an adjustable guide frame l which is more specifically described in my guide patent application Serial No. 680,049, filed July 12, 1933, and is herein shown to illustrate any suitable type of adjustable striper guide as may be mounted thereon for forming contact with a guide rail or template for guiding the striping device over painted surfaces on which stripe lines are to be made. The guide unit 4 herein shown comprises a thirnble block n formed with a cylindrical hole p therethrough for fitting and sliding over the guide thiinble 2, the top edge of the block being slotted and the section tightly clamped to the thimble 2 by the threaded bolt and nut 5 and 6 mounted therein. A key '7 is formed on the outer surface of the thimble2 and engages a corresponding key recess through the thimble block n, allowing a longitudinal adjustment thereon. An adjustable guide block 7' having slide rods 8 fixedly mounted on opposite sides thereof, is slidably mounted on the lower side of the thimble block 11 and clamped thereto in any adjusted position by contact of the threaded bolt and nut 5 and 6 which engage the surface of the slide rods s when screwed together. Guide arms 8 with ball tipped ends are rigidly mounted on the outer face of the'guide block 1", positioned at right angles thereto, and adjusted, when in a released position, with the ball tips slightly back of the striping nib disc g, as shown in the Fig. 5 of the drawings. The guide block r and attached arms 8 may be adjusted as required to engage any guiding ridge or template edge u as may be used or provided on the surface to be painted. Through the inner end of the striper unit body section 0 is formed a key recess 12 and which carries a curved key bar 9 mounted therein, said key bar ends being projected outside of the body walls and engage corresponding key ways formed in the shouldered end section Z of the guide thimble 2, thus preventing any rotation of the striping unit within the thimble, yet free to slide lengthwise thereof. The inner end of the paint passage channel is is threaded and carries mounted therein a cylindrical stud hub 10 with threaded end tightly screwed therein, positioned concentric with the striping unit axis. The hub 10 is formed with a cylindrical body to having an annular feed groove :13 positioned near the center thereof, and provided with radially positioned port holes 3/ opening into a centrally positioned passage channel e which is extended aximetrically through the hub 10 and opens into the striper unit channel 7c. The hub 10 is provided with a recessed end head 11, and carries mounted therein an irregular shaped spring Washer ring 12. Rotatably mounted on the channel hub 19 is a cylindrical shaped feed collar 13, fitted thereto and free to rotate thereon to any desired position about the axis of the striper unit 1, and is retained in such chosen position by the spring pressure of the spring washer ring 12 which engages therewith. The feed collar 13 is provided With a side hub 14, and is formed with a paint passage 15 positioned radially therethrough, opening directly into the annular groove :0 of the hub channel 10 On the outer end of the hub 14 is mounted a hollow paint container 16, preferably formed pear shaped, positioned at a chosen angle with the striper unit axis, and is swivelly connected to the hub 14, preferably by a swivel joint as illustrated in Fig. 6 of the drawings, or may be connected by a threaded stud 1'7 as illustrated in Fig. 12 of the drawings, the container 16 being capable of one complete rotation about the connecting joint. The container tank 16 is provided with a threaded cap 18 at the upper end thereof for filling and closing the tank with liquid striping unit, and is formed with a small outlet port 19 through the swivel joint connection, and opening into the feed collar hub channel 15, providing a continuous passage channel from the container 16 to the striping nib disc g, for all positions of both the container 16 and feed collar 13. Through the collar 14, is slidably mounted a feed control valve 29, preferably formed of a cylindrical body section a, having a centrally positioned annular valve groove b and an end operating groove 0 formed therein, although the modified forms as illustrated in Figs. 10 and 11 may be used if desired, said control valve 20 being positioned through the hub 14 parallel to the axis of the channel hub 10, and mounted with the end operating groove 0 engaging the end collar 2 of the guide thimble 2 while the central annular valve groove 1) or port 19 is positioned at one side of the paint passage 15 when the guide thimble is unstrained, as indicated in the Fig. 5 of the drawings, the valve stem a completely closing the paint passage 15, preventing leakage of the liquid paint from the container 16 when the device is not in use.

When the paint container 16 is filled with the desired striping paint, the user in applying the device will hold the striper unit in his finger tips by grasping the sides of the guide frame 4, then placing the contact edge of the striping disc g against any painted surface t, as indicated in the Fig. of the drawings, and applying pressure thereto sufiicient to displace the striping unit body 27 within the thimble 2 as illustrated in the Fig. 6 of the drawings, and which also displaces the connected feed control valve 20 within the hub 14 by reaction of the connecting guide thimble flange 11, opening the paint passage 15, allowing the striping paint to flow through the connecting channel passages directly to the striping disc 9. The striper is operated in the ordinary manner by moving the device along the painted surface t, rolling the striping disc 9 thereon, the control valve being held open as long as pressure is applied to the guide frame unit, but closes as soon as the pressure is released, the valve andstriping unit returning to its closed position as shown in Fig. 5, under reaction of the inclosed spring 3.

The operating valve end groove 0 being fitted over the flange i of the thimble collar 2, allows the feed thimble 13 and connected paint container 16 to be rotated about the hub to any desired position so as to retain the container above the striping unit 1 causing a gravity feed for the paint liquid therethrough for any position of the striper. The swiveled paint container as connected to the hub collar 14 also provided a further adjustment of the tank 16 when the striper is being used on vertical or inclined surfaces, the container being turned to a forward position as indicated by the dotted position 16' in the Fig. 5, retaining the paint supply above the striper nib disc 9.

While I have illustrated the preferred design of my universal striping device, it is to be understood that various modifications in both general design and mechanical elements may be made without departing from the spirit of my invention, that any suitable type of paint striping nib, guide frame or operating valve may be substituted for the respective parts shown herein, and I claim the design as heretofore described and illustrated and any other design that is substantially a substitution of the various parts and units herein shown.
