11 Claims.

This invention relates to an improved striping device.

Heretofore in applying paint stripes on articles with conventional striping devices, considerable difficulty has been encountered in starting the paint to flow at the commencement of a stroke immediately upon initial contacting of the pens of the device with the work, and in stopping the flow of paint when the pens are lifted at the end of each stroke. Attempts to remedy this condition have been made by providing valves for controlling the flow of paint which are operable by valve stems that protrude through and beyond the outlets of the pens. With such valve structures, and any other apparatus which relies upon linear movement, it is necessary to retain the nozzle in a disadvantageous position substantially normal to the surface upon which the stripes are being formed. The scraping contact of the valve stems with the work during movement through the stripe applying strokes frequently scratches ing device to be held at an inclination to the surface of the work during operation without obstructing the outlet of the pen; to provide a swiveled nozzle in a device of this character which is universally tiltable in all direction relative to the body of the device; to provide improved means for yieldably holding the swiveled nozzle in axial alignment with the body portion; and to provide paint conducting passages in the swiveled nozzle and body portion which do not communicate with each other when the nozzle is in axial alignment with the body portion, but which are adapted to be brought into communication with each other by tilting of the nozzle in any direction relative to the body portion of the device as the striping is applied to the work.

Further objects of the invention are to provide a swivel nozzle in a device of this kind which has a pair of pens for forming spaced stripes; to provide separate passages in the swiveled nozzle for feeding a different colored paint to each pen, respectively; to provide separate passages in the body portion for supplying a different colored paint to each passage of the nozzle and which communicate with their corresponding passages of the nozzle only when the latter is tilted at an inclination to the body portion so as to enable starting and stopping of the flow of paint to the pens as the latter are applied to and removed irom the surface of the work, respectively; and to provide a swivel nozzle which rotates freely relative to the body portion during application of the pens to the surface of the work so as to equalize the pressure upon the pens.

An illustrative embodiment of the invention is shown in the accompanying drawings, in which:

In the form shown in Figs. 1 to 5 inclusive, my improved striping device includes a tubular body portion 1 having a passage 2 for conducting paint, preferably fed by gravity, from a tank 3 through a flexible hose 4. The tubular body portion has an enlarged head 5 having an inner recess 6 in which a seat '7 is fixed. The seat '7 includes a convexed spherical surface 8 having an open circular groove 9 which is substantially concentric with the axis of the body portion 1. The groove 9 connected by passages 10 with the passage 2 of the body portion.

Formed at the outer end of the enlarged head 5 is a recess 11 into which a nozzle 13 is extended. The nozzle 13 has a head portion 14 on its inner extremity which is provided with a convexed spherical surface 15 that conforms with and abuts against the concaved spherical surface 8 of the seat 7 Formed in the nozzle is a passage 16 having one extremity open at the spherical surface of the head 14 and having branch passages 17 leading to the outer extremity of the nozzle. Striping pens 18 communicate with the branches 1'7 and are threaded on the outer end of the nozzle. These striping pens have outlets 19 at their extremity and adjacent tapered side portions 20.

The nozzle is tiltably mounted, or universally swiveled on the enlarged head 5 of the body portion 1 and is yieldably held against displacement by a sleeve 21 which is slidably mounted in the recess 11 and which has a radial flange 22 that bears against a shoulder 23 on the head 14 of the nozzle. The sleeve 21 is yieldably urged inwardly by a coil spring 24 which bears between the flange 22 of the sleeve and the end of a closure, or cap 25 which is externally threaded on the enlarged head 5 of the body portion. The cap 25 is provided with an opening 26 which is substantially larger than the portion of the nozzle with which the cap registers so as to permit a limited univerwith respect to the circular groove 9.

sal wobble movement of the nozzle relative to the body portion.

The spring 24 and sleeve 21 firmly hold the spherical surfaces of the head of the nozzle 14 and the seat 17 in firm contact with each other and they also yieldably hold the nozzle substantially in alignment with the body portion, as illustrated in Fig. 2, so as to retain the inner open ends of the passage 16 in non-registering relation In the form shown in Figs. 1 to 5, the inner end of the passage 16 is closed by that portion of the concaved spherical surface 8 of the surface '7 which is included within the circular groove 9.

In operation, the striping device is held at an inclination to the surface of the work upon which stripes are to be applied, as illustrated in Fig. 3, and as the striping pens 18 are urged against the work with a slight pressure, the nozzle is tilted relative to the body portion sufiiciently to bring the open inner extremity of the passage 16 into registration with the open circular groove 9. When the parts are in this relation paint flows from the passage 2 of the body portion through the passage 16 of the nozzle to the outlets 19 of the striping pens. The striping pens are held at an inclination to the surface of the work and rested upon their tapered side portions 20 and the outlets 19 of the pens are unobstructed during the movement of the devices. When the nozzle is tilted during the stripe applying strokes, the radial flange 22 of the sleeve 21 bears upon the shoulders 23 of the head of the nozzle at a substantial distance from the axis of the nozzle, as illustrated in Fig. 3, and considerable force is exerted on the nozzle, tending to return it to its normal position in alignment with the body portion of the device. When the striping pens are lifted from the surface of the work at the end of a stroke, the sleeve 21 and spring 23 rapidly return the nozzle to its normal position and immediately cut off the supply of paint to the pens so as to obviate dripping of paint upon the work or widening of the stripe at the end of each stroke of the device. The central portion 26 of the concaved spherical surface of the seat 7 forms a sufiiciently tight shell at the inner end of the passage 16 to prevent either paint or air from entering the passage 16. As a result, the paint which remains in th passage 16 after the nozzle has been returned to its normal position is prevented from flowing out of the passage and is retained in readiness for the next stroke of the device.

In Figs. 6, 7 and 8 is illustrated a modified form of my improved striping device which is adapted to simultaneously form stripes of different colors. The structure of the device is mainly identical to that shown in Figs. 1 to 5 inclusive and corresponding parts of the structure are designated by the same numerals used in the description of Figs. 1 to 5. The tubular body portion 2, however, is provided with a pair of passages 27 and 28 for conducting diiferently colored paints respectively, and the nozzle 13 has a pair of passages 29 and 36 for feeding the diiferently colored paints to the striping pens 18. Formed in the concaved spherical side of the seat 8 are a pair of spaced outer grooves 31 which communicate with the passage 27 of the body portion through passages 32 in the seat 7. An inner circular groove 33, which communicates with the passage 28 of the body portion through passages 34, is provided at the central portion of the concavedside of the seat. The passage 29 of the nozzle has an outwardly extending end portion which normally registers with that part of the concaved surface of the seat which is located between the spaced grooves 31 and the open extremity of the passage of the nozzle registers'with that portion of the concaved side of the seat '7 which is inclosed within the inner circular groove 33 when the nozzle is in its normal position.

When the nozzle is tilted downwardly to the position illustrated in Fig. 7, by application of the striping pens to the surface of the work, the open end of the passage 29 registers and communicates with the outermost groove 31 and the open end of the passage 30 communicates with the up per side of the groove 33. If the nozzle were tilted upwardly from the position shown in Fig. 6, the open end of the groove 29 would register with the inner groove 31 and the open end of the passage 39 would register with the lower side of the groove 33. Regardless of the direction in which the nozzle is tilted, the open end of the passage 29 is brought into communication with one of the grooves which is supplied with paint of a different color from the passage 28 of the body portion.

In the form shown in Figs. 9, 10 and 11, the striping device includes a body portion 35 having passages 36 and 37 for conducting differently colored paints, respectively. Seated in a recess 38 in the enlarged head 39 of the body portion 35 is a seat 40 having a concaved side 41 against which a convexed extremity of a nozzle 42 is yieldably held by a coil spring 43 and a shiftable sleeve 44. The coil spring 43 bears between a cap 45 threaded on the enlarged head 39 of the body portion and a radial flange on the shiftable sleeve 43.

Formed in the nozzle 42 are passages 46 and 4'? which communicate with striping pens 48 mountedon the outer extremity. of the nozzle. The inner end of the passage 46 has a pair of branches 49 each of which communicate with a circular groove 50 formed in the spherical convexed extremity of the nozzle. The passage 4'7 has an open extremity which communicates with a groove 51 which is also formed in the convexed extremity of the nozzle. A passage 52 in the seat 40 communicates at one end with the passage 36 of the body portion and it registers at its other end with that part of the convexed extremity of the nozzle which lies between the grooves 50 when the nozzle is in its normal position. The seat 40 also has a passage 53 which communicates at one end with the passage 37 of the body portion. The other end of the passage 53 registers with that portion of the convexed extremity of the nozzle which is inclosed within the circular groove 51, when the nozzle is in its normal position.

When the nozzle is tilted by application of the striping pens to the surface of the work at least one of the grooves 50 registers with the passage 52 of the seat 40 and permits paint of one color to flow from the passages 36 of the body portion to one of the striping pens. This tilting of the nozzle also bring the grooves 51 into registration with the outer end of the passage 53 which permits paint of a different color to flow from the passage 37 of the body portion to the other striping pen. When the striping device is lifted from the surface of the work the nozzle is returned to its normal position in alignment with the body portion and all of the grooves in the convexed extremity of the nozzle are rotated out of registration with the passages 52 and 53 and therefore the supply of paint to both nozzles is immediately discontinued.

Although but several specific embodiments of this invention have herein been shown and described, it will be understood that various changes in the size, shape and arrangement of parts may be made without departing from the spirit of my invention and it is not my intention to limit its scope other than by the terms of the appended claims.
