This invention relates to striping devices particularly adapted for the purpose of applying different colored stripes to automobile bodies, such as along or adjacent the belt line' molding or around the window reveals.

An object of the invention is to provide a striping device which may be used by unskilled workmen to apply one or a plurality of stripes to the body rapidly and in an efli-- cient manner, and in which different width stripes may be applied by the same device or in which any number of stripes different distances apart may be applied at the same time.

Another object of the invention is to provide a-striping device which may be moved over the body panel more easily and rapidly while enabling a better and more clearly de fined stripe to be produced without requiring 0 any particular skill to'produce this result. One of the features of the present invention resides in the factthat the feed of paint or striping fluid to the applicator may be automatieally increased or decreased by centrifugal action during operation in proportion to the speed of movement of the device.

Other objects of this invention will appear in the following description and appended claims, reference being bad to the accompanying drawing forming a part of this specification wherein like reference characters designate corresponding parts in the several views.

Fig. 7 is a detail sectional view illustrating different types of applicators which may be interchangeably use Referring to the drawings wherein I have shown for the purpose of illustration a striplng device embodying my invention, the device may comprise a suitable support 9 provided with a suitable reservoir 10 for containing the paint or other striping fluid. This reservoir has a detachable cover 11, and the device is provided with a handle or hand grip 12. The support has a downwardly extending arm 13 provided with a passage or duct 14: communicating with the interior of the reservoir 10 and providing a gravity feed. The free end of the supporting arm 13 is turned down at 13a and threaded to provide a means whereby different types of appllcators may be interchangeably connected to the supporting arm 13.

In the construction shown in Figs. 1 and 2 the striping instrumentality comprises a rotary disk. Where a single stripe is to be made on the body panel, a single striping disk will be employed, and the construction is such that disks of different sizes may be interchangeably used depending upon the width of stripe desired or a plurality of striping disks may be connected to the sup- 1 port 13 where a plurality of parallel stripes are to be made. In Figs. 1 and 2 I have shown by way of example three disks assembled in position on the supporting arm 13, as a result of which three parallel stripes may be simultaneously made. The striping disk in the present instance is rotatably mounted on the end of the arm 13 through the medium of a ball bearing comprising a collar 15 screwed onto the threaded end 13a of the arm and a pair of revoluble members 16 and 17 having cooperating threaded portions, and between which and the collar 1 extension similar to the threaded portion 13a to which may be attached any one of the disks 18 illustrated in Figs. 1 and 2, or the modified type of disk 35 illustrated in Figs. 5 and 6. Each of the striping disks 18 comprises a central hub 19 having at one end. a tapped bore adapted to be screwed onto the threaded extension 17a of the bearing member 17 and having at the opposite end a threaded portion 20 to which may be attached another striping disk 18 in the manner shown in Fig. 2. From this construction it will be seen that each disk 18 may be interchangeably connected to the end of the bearing member 17 and to any one of-the other disks so that if desired a plurality of striping disks may be assembled together and to the end of the supporting arm 13.

A cap 22 having a tapped bore may be screwed on to the threaded end 20 of any one of the hubs 19, and this cap is conical to provide, as in the construction shown in Fig. 2, a bearing member capable of being seated in a conical recess in an adjustable bearing member 23. The latter terminates in a sleeve portion 23a drilled to receive a supporting rod 24. This rod is adjustable within acylindrical hole 25 in a tubular extension 26 of the body. The rod has a longitudinal keyway 27 and may be clamped in adjusted position by means of a set screw 27a extending into the keyway to hold the supporting rod 24 against turning.

In like manner the sleeve portion 23a of the bearing 23 may be clamped in adiusted position on the rod 24 by means of a set screw 28 proiecting into the keywav 27 to hold the bearing against turning on the rod The bearing members 15. 16 and 17 have an axial bore registering with the duct 14 and the fluid is conducted from the duct 14 into the axial bore 29 of the striping disk 18 by means of a tube 30 extending through the bearing 15-17. The uner end of this tube has a laterally extending annular flange which is clamped between the end of the arm 13 and the shoulder of the tapped counterbore of the member 15 as shown in Fig. 2. It will be seen that a continuous passage is provided from the chamber 10 to the axis of rotation of each striping disk 18 by means of the duct 14, tube 30 and duct 29. Each disk may comprise a hollow annular body fixed on the hub 19 through which extend radial ports 31 into the chamber 32 of the hollow disk body. The periphery of the disk 18 is provided with an annular applicator pad 33 which may be composed of felt, sponge, or other porous material providing a yielding pad. The fluid may pass from the hollow body 32 into the pad by means of a series of ports 34.

In Figs. 5 and 6 I have shown a. somewhat modified type of rotary striping disk. This disk 35 also comprises a central hub 35a having spaced radially projecting flanges 36 suitably spaced at the periphery thereof to enable a stripe of the'desired width to be applied. The flanges 36 are held'under tension in adjusted position by means of caps 37 screwed onto the opposite ends of the central hub member 35. striping disk 18, the hub of the disk 35 is constructed so that it may be attached to the end of the bearing member 17 by means of a tapped bore 38. This hub is also provided with a threaded extension 39 to which-may be attached another striping disk or the hearing cap 22. The hub is drilled centrally to provide an axial fluid passage 40 and fluid is conducted to the flanged nibs 36 by means of radial tubes or ducts 41.

In Fig. 7 I have illustrated the manner in As in the case of the Y which two other types of applicators 42 and 47 may be interchangeably employed if required. The applicator 42 is shown as a pen having a base 43 which is drilled to provide a fluid passage 44 communicating with the passage 14 of the support 13. This base 43 of the pen has a tapped eounterbore adapted to be screwed on to the threaded extension 1311 and also has a threaded extension 43?; to which may be attached either another striping pen as shown in Fig. 7, or a spacer member 45, or the bearing cap 22. In Fig. 7, I have illustrated a spacer member 45 interposed'between the base 43 of the pen 42 and the base 46 of a striping brush 47, this type of applicator being shown for illustrative purposes. The base 46 is also provided with a fluid passage 48 alined with the passage 49 extending through the spacer 45, the passage 49 being alined with the passage 44. The cap 22 is screwed onto the threaded end of the member 46 closing the end of the fluid passage.

The paint or fluid is conducted from the duct 44 to the pen 42 by means of a tube 75, and is conducted from the duct 48 into the brush 47 by means of a tube 76.

Referring to Fig. 4, it will be noted that the spacer 45 is drilled axially to provide a duct 49. One end is counterbored and tapped at 450 to permit the spacer to be screwed onto any of the threaded portions 13a, and 20 or to be attached to either of the parts 43 and 46 of the applicators 42 and 47. The opposite end of the spacer 45 is turned down and threaded at 45?). So that from the construction it will be understood that the proper positioning of the applicators with reference to the support 9, or the desired spacing of the stripes where more than one stripe is being made may be-obtained merely by proper interchanging of the parts.

As illustrated in Figs. 1 and 2, the striping device is provided with a guide which may be adjusted into various positions in order to determine the position of the stripe on the body. When making a stripe along or adjacent the belt line molding M the guide 50 travels along this molding and by ad-.

' the action of a spring 55 and this movement is limited by means of a suitable pin and slot connection 56. In this manner, it will be seen that the guide 50 is mounted to yield by virtue of the spring 55, and may be adjusted longitudinally within the head 52 or it may be adjusted bodily by adjusting the rod 24 within the bore 25 of the tube 26.

The flow of fluid from the reservoir 10 through the duct 14 is controlled by means of a valve 60. This valve in the present instance is of the rotary type which may be rotated into one position to close the passage or into position to open the passage and this operation is accomplished by means of a trigger device 61 located adjacent the hand grip 12 so that it may be operated by the index finger of the workman. The trigger 61 is controlled by a spring 61a and is secured to a spindle 62 to which is pinned a link 63. The link 63 has a lost motion connection, by means of apin and slot 64, to a link 65 pinned to the spindle of the valve 60. When the trigger 61 is in the full-line position shown in Fig. 3, the valve will be closed as shown in Fig. 2. When operating thestriping device to form a stripe on the body, the trigger 61 is retracted to the dotted line position shown in Fig. 3, thereby operating the mechanism as shown in dotted lines in the figure pesulting in turning the valve into open posi- It will be seen that the paint or other striping fluid is normally fed from the reservoir 10 through the conduit 14 to the axis of the striping disks by gravity. As the device is moved along the body panel, it will be understood that the disks are rotated more or less rapidly as a result of which the fluid will be spread evenly to the periphery of the disk by centrifugal action.

It is important that a proper supply of I paint be fed to the periphery of the disks and this supply should increase in proportion to the speed in which the device is moved over-the body. When the device is moved slowly over the body panel a suificient supply of fluid will be obtained by the gravity feed, and due to the rotation of the disks the paint will spread from the axis of rotation to the periphery in an even and uniform manner. As the movement of the device is increased however, the feed is increasingly assisted by centrifugal action set up by the rapid rotation of the disks. Hence it will be seen that by virtue of this construction the supply of fluid will be increased or decreased at the periphery of the striping disk in proportion to the speed of travel of the device over the body.
