ADJUSTABLE PAINT STRIPING DEVICE Filed July 29, 1952 2 Sheets-Sheet 2 Patented Nov. 19, 1935 UNHTED STATES PATENT OFFICE 4 Claims.

My device relates toan adjustable paint striping device, and is a modification of my former paint striper shown and described in my former patent application Serial No. 484,283, filed Sept.

25, 1932, and the special striping nib herein illustrated is more fully set forth in detail in said former application. The improvements herein shown and claimed are applicable to any other type of tubular paint striping unit equally as well, although I have chosen to illustrate it as applied to the specific nib as set forth in the former patent application.

The object of my invention is to produce an adjustable paint striping device that is adapted for following any irregular guide strip and operate in various positions thereon.

Another object isto produce a paint striping device that is interchangeable on position and can be reversed to operate in different directions.

A further object, is to produce an adjustable paint striper having a swiveled paint container capable of being retainer in a vertical position regardless of the position of the striping nib.

A still further object is to produce an adjustable guide means for a paint striping device that will retain the marking unit in any predetermined position along a painted wall, and with the guide members adjustable to various positions thereon.

-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.

In general, my device comprises a tubular paint 20 striping nib, of any chosen design, slidably mounted within a. tubular. casing member, and held in position by aspring member mounted therein, said tubular nib being rotatable to various positions within the casing. The striper 25 nib carries rotatably mounted thereon a swiveled paint container connected to the striper nib point by an intervening channel passage and opening therein at all positions. An adjustable guide block with adjustable guide arms is slid- 30 ably mounted on the tubular casing end and positioned to surround the nib point in all of its various positions.

I will now describe more fully the detailed construction of my device referring to the draw- 35 ings and the marks thereon.

The nib l is more fully described in my former patent application referred to, Serial No. 484,283, filed Sept. 25, 1930, and comprises a tubular body.

a flattened at the outer end point and is formed 40 with a central liquid passage b lengthwise therethrough and terminating in a cylindrical chamber c at the outer nib point. The chamber 0 carries rotatably mounted therein a pinned surface striping wheel d partially surrounded by a spring disc'shield c, said shield being designed to'regulate the flow of paint therethrough. A small adjusting screw 1 is mounted in the nib point for adjusting the spring end to the pinned surface of the wheel. The inner end of the nib I is formed with a cylindrical end collar a provided with paint groove and ports h and k which leads directly into the paint passage channel b. A small liquid paint container m formed with acylindrical end bearing 11. is rotatably nib l and is retained thereon by the end collar p. screwed within the inner end of the liquid channel b. The paint container in is'preferably positioned at an angle leaning back from the nib point and is rotatable thereon to any position about the collar end. The container m opens directly into the collar groove and ports 72. and is providing a clear passage from said container to the nib point for all positions of said container. A small airport q is formed through the container cover r and may be closed by the disc 3 pivctally attached thereto.

The cylindrical paint striping nib I is slidably mounted within the shouldered end if of the tubular casing 2, said tubular end preferably being formed by inserting the smaller tube sec- 3 in the wall slots i and 5.

tion 73' Within the casing end and fixedly attaching the same thereto by welding. A guide pin 25 is fixedly mounted on the top side of the cylindrical striping nib I, and is positioned there into engage the recess slots and 5 formed in the top and bottom walls of the casing end 77, positioned diametrically opposite each other, and retains the striping wheel (1 in a plane at right angles thereto. The nib i is firmly held in its extreme end position as shown in Fig. 1 of the drawings by a coil spring 6 mounted within the handle end of the casing 2. An adjusting operating rod i is fixedly attached to the threaded plug collarp of the nib I, or made a part thereof,

and is extended aximetrically through the casing 2 and projected out through the casing end cap 8, providing means for withdrawing the nib I within the, casing end t and reversing the nib position'and changing position of the guide pin By reversing the position of the nib I within the casing, the striping wheel d is also reversed in position and the striper may be operated in the opposite direction. As the nib i rotated within the casing 2, it also rotates within the bearing n of the paint container m, and at the same time the container in may be rotated from one side of the casing to the other through the casing wall slot 3 as indicated by the dotted positions m of Fig. 8 of ing wheel (1 of nib i.

the drawings. The wall slot 9 is formed of sufficient length to allow the Withdrawal of the assembled unit for changing position and adjusting the nib I to either of the wall slots or'5 for changing position of the striping wheel 01. In using the striping device along irregular lines of travel such as turning from a horizontal to a vertical direction, the container m may be rotated from one side to the other through the casing slot 9 by the user, forretaining the container in as nearly a Vertical position as possible, assuring constant pressure and flow of the liquid paint through the striping nib as possible. Likewise the tilting of the container m at an angle back from the nib point allows the paint to flow therethrough even though the striper is applied to a painted surface in a vertical position as when striping on a flat level surface.

Mounted over the shouldered end i of the easing is a rectangular guide block it], said block being formed with a centrally positioned cylindrical opening therethrough which fits and slides over the tubular endsection t, and is positioned thereon, at right angles to the plane of the strip- The block I0 is retained fixedly thereon by a small thumb screw i I engaging one of the parallel wall slots I2 formed in the casing tubular end, said slots I2 being preferably positioned on opposite sides of the tubular section a mounted on the inner end collar or of the striper t and in a plane through the center of the strip ing wheel at. Along opposite edges of the rectangular guide block Iii and at right angles to the surface of wheel (2, are formed parallel slot grooves i3 which extend the full length of the block walls. Within the, slotted grooves I3 is fitted'a U-shaped guide arm yoke I4 slidably mounted therein, said yoke being held in various chosen positions therein by a headed lock bolt and nut i5 and I 6, said bolt I5 being positioned 1 through the guide block I 0 adjacent the edges of the yoke I4 and tightly clamped thereon by the threaded nut I6. It is desirable to form the grooves I3 adjacent one of the side faces of the caster, said ball w being retained in the arm end by thespherical casing wall a: and supported on 25 a small bearing 'ball ,1; mounted Within. the easing'base, thus ailowing free rotation of the ball 10 in every direction. The position of the guide arms I? may be adjusted along a line at right angles to the surface of wheel d by sliding the 3 supporting yoke I l along the grooves I3. Also at the top of the guide block Iii opposite the guide arms ii ismounted a single adjustable guide arm id'and which is slidably mounted through an opening forinedin the guide block Wall and posi 3 tioned parallel to the casing axis. The arm I9 is formed with an end ball tip similar to that of the arms I? and is fixedly retained in the block a recess 2 by a small thumb screw 29 tightly screwed therein. The arm I9 may be. adjusted longitudi- 40 a .45 Inasmuch as the striping wheel d is operative in one direction only due to the inclosing adjustable spring shield e and regulating screw used therewith, it becomes necessary to reverse the position of the nib I within the casing 2 whenit 5 is' desired to operate the-striper in the opposite direction, and to accomplish this the nib I is withdrawn within the casing 2 against the compression spring 6 by the connected operating rod luntil the guide pin 3 is free from either recess 5 I or 5,-.and which allows the nib to be rotated within the casing to its opposite position and reentered in the opposite recess. The striper is then ready for use in the reverse direction. .The receding adjustment of the nib against the spring 6 6 allows for irregular surfaces and variations therefrom even though the guide arms travel a uniform path along the guiding surface.

It is apparent that my device is subject to various modifications in both design and structure 6 and without departing from the spirit of my invention, and also that my device is applicable to use with various types, of paint striping nibs, and I claim as my invention the device herein illustrated and any other structure that may be sub- 70 prising a tubular casing member, a cylindrical plug paint striping nib having a rotatably mounted marking disc slidably and rotatably mounted within one open casing end, said casing and nib being provided with pin and slot means for retaining the nib in various pre-determined positions within the casing end, spring means mounted within the casing for engaging the nib and retaining the same in some of its various end positions, a paint container mounted on said casing and rotatably connected to the striping nib in a manner capable of flowing liquid paint therethrough for all positions of said nib within the casing, and adjustable guide arms slidably mounted on the casing end positioned on opposite sides of the striping nib point.
