2 Claims. 1

My invention relates to a paint striping instrument especially adapted to automobile body and machinery striping, and like work.

The object of my invention is to produce a universal paint striper that will operate automatically, and will seal the paint flow channel Whenever the striper is released.

Another object is to provide a universal striper, equipped with interchangeable striping units, all connected with the paint supply channel, and operative by automatic means.

A further object is to provide a universal paint striping instrument that is simple in construction, easily and efficiently operated, and that can be manufactured at a very low cost.

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

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

Fig. 5 is another longitudinal sectional view taken on the line 5--5 of the Fig. 1, showing the channel connection between the adjoining tubular frame sections, and the closing valve therebetween.

Fig. 6 is also a cross-sectional view taken on the line (i5 of the Fig. 1, showing the clamp recesses for the respective striper units.

Fig. '7 is a cross-sectional view of the universal striper head disc taken on the line 17 of the Fig. 1, showing the radial paint passages leading therethrough to the respective striping units.

Fig. 8 is an enlarged cross-sectional view of one of the striper units also taken on the same line 'i-'i of the Fig. 1, showing the detailed construction of a striper unit assembly.

In general, my universal paint striper comprises a hollow tubular handle casing, provided with an angularly positioned striper head frame threadably mounted on one end thereof, and which carries a multiple head disc rotatably mounted on the outer end thereof, each bearing different types of striping units. The tubular casing and connected mechanism are provided with connected valve, and control means for automatically operating the striper.

I 111 now describe more fully the detailed construction of my device, referring to the drawings and the marks thereon.

The paint chamber is made of a tubular casing I, closed at one end, but having a paint channel 1* formed therethrough along the casing axis, and is provided with a closing cap 2! threadably mounted within the outer end thereof. The casing is preferably made of light m'tal, such as aluminum, or any other suitable metal. The closed casing end a is formed with a threaded end connecting nipple. b projected therefrom, positioned concentric with the casing axis, and carries threadably mounted thereon a striper head section 3, preferably designed and posi tioned at a predetermined angle with the attached casing I. The head section 3 is cylindrical in form and made of the same material as the casing, and is designed with an end slot recess 4 of uniform width, positioned symmetricallywith the section axis, cross-wise thereof, as indicated in the Fig. l of the drawings. A circular striper head disc 5 is rotatably mounted within the re cess 4 by means of the bearing pin 6 fixedly mounted cross-wise through the head section slot walls, and at right angles thereto. Suitable disc striper units 7, eachof a different width, are radially mounted on the striper head disc 5, uniformly positioned thereon, and provided with radially positioned paint channels 0 leading to each of said units I. Each channel 0 opens into the central disc head bearing d, as illustrated in the Fig. 7, showing three striper units in combination, although more striper units may be applied, if desired. Each striper unit '5 is formed of a hollow casing section e, flattened and open mounting g for fixedly mounting same in the head disc 5, by pressed fit within the disc recess, or any other suitable means, and are provided with paint passage channels 71., connecting the striper head disc channels c with the respective striper discs y". The bearing pin 6 is provided with an off-set S-shaped paint passage it formed therein, designed with the inner passage end opening along the head section 3 centerline toward the outer end thereof, positioned to coincide with one of the head disc paint passages c the respective striper units l are rotated to their operative end position, and as indicated in the Figs. 1 and l of the drawings. The striper head disc 5 is held in operative position by the thumb screw 8 threadably mounted in the head section 3 slot wall, positioned therein to engage the corresponding loci; recess in of the disc 5 opposite the chosen striper unit l, securely clamping said disc 5 in operative position. The outer end of the S-shaped paint passage is of the bearing pin is extended to one side of the head section and opens into a side paint passage p extended along the outer section wall and into the threaded head mounting re ess c; coinciding with the tubular casing paint passage r, providin" a complete and continuous paint passage from the paint chamber A to the selected operating striper unit 2 positioned at the outer head section end. A special plunger valve 9 is slidably mounted across the closed end of the tubular casing l through the cylindrical valve chamber 3 petitioned to intersect the paint passage r at right angles thereto. The valve plunger 9 is provided with a valve port t positioned cross wize thereof to coincide with and intercept the paint passage 7 when said valve 9 is fully depressed within the valve chamber, thus auto znatically opening the paint passage for striper operations, or closing said paint passage when said valve 9 is displaced by reaction of the attached coil spring EU, as shown in the 5. Along one side of the tubular casing i, near the central section thereof, is fixedly mounted a slotted bearing pin ii, and carries pivotally attached thereto, an operating lever l2 extended nearly the full casing length and is provided with a thumb plate V at the inner end thereof. Near the inner end of the lever i2 is pivotally attached the projected end of the valve plug 9, outside of the attached coil spring ill, and provides convenient means for opening the paint passage valve whenever the paint striper is to be used. The opposite end or the lever ill is pivotally attached to a special tapered air valve plug it mounted through a conical wall port 2:; positioned near the capped end or the casing, allowing air to be admitted within the paint chamber A during painting operations, for relieving any vacuum as may be caused by the paint flow therefrom. Both of the valves it and are automatically closed by release of pressure on the thumb plate V. When the proper striper unit l has been selected and positioned, the head disc locked in place, the striper is then ready for operation, and will function automatically as the thumb plate V is depressed by the operator.

Having fully described universal paint striper, what I claim as r y invention and de sire to secure by Letters Patent is:

l universal paint striper, compri ing a tubular body formed with a closable paint chainher therein, a body head section mounted on one end thereof angularly positioned thereon, a circular head disc having a central bearing recess 'rotatably mounted Within the outer end of the section on a fixed cylindrical bearing pin formed with an S-ehaped paint passage th rethrough having side inlet and outlet ports, a disc locking s-cew mounted in the head section, positioned therein to engage the head disc predetermined paint striper units fixedly mounted around the outer head disc circum- Terence, positioned radially thereon, radially positioned paint passages formed through the head disc leading from the central bearing recess to respective disc striper units, each engageable with the bear ng pin s shaped paint passage outlet port positioned along the head disc centerline when disc is rotated to the forward outer position thereon, an inlet paint passage formed lengthwise the head section connecting the paint chamber with the bearing pin S-shaped passage inlet port, and means for conlllng the paint flow through the paint passage.
